The invention relates to the technical field of screen printing and discloses a screen printing method. The screen printing method includes: providing a screen, wherein the screen comprises a screen frame and screen cloth stretching tight on the screen frame, the screen cloth is provided with a pressing figure mold forming a plurality of grids by cross arrangement of a plurality of parallel warps and a plurality of parallel wefts, and the warps and the wefts are mutually vertical; providing a substrate, attaching the screen to the upper surface of the substrate, applying coating materials on the position corresponding to the pressing figure mold of the screen cloth, and using a scraper to press down to abut against the screen cloth prior to moving the scraper so as to enable the coating materials to be distributed according to the pressing figure mold, wherein the latitude line of the scraper and the pressing figure mold forms a first included angle, the longitude line of the scraper and the pressing figure mold forms a second included angle, and neither the first included angle or the second included angle is zero degree; removing the screen to form printing patterns on the substrate. The invention further provides a screen structure and a pressing marker, and reject ratio of screen printing can be reduced.

The invention discloses a connector pin and a production process thereof and belongs to the automobile fitting field. The connector pin comprises a material belt and a pin, wherein the material belt comprises a sheet material and a U-shaped clip arranged on the sheet material, and the pin is embedded into the clip. The production process comprises sheet material stamping, cutting and folding to form the material belt, pin cutting, inserting the pin into the clip and molding. The connector pin is advantaged in that the connector pin can be widely utilized, square needles, circular needles and flat needles which are applied to all the connectors can be processed, production precision is high, a smooth surface and stable profile dimensions are realized, production cost is low, and efficiency is high.

The invention relates to a preprocessing method of a flexible substrate. The flexible substrate includes a flexible substrate body and a glass base material; one side of the flexible substrate body isprovided with a protection film. The preprocessing method of the flexible substrate includes the following steps that the flexible substrate body is adopted, the side, away from the protection film,of the flexible substrate body is attached to the glass base material, a precut position is formed on the flexible substrate body, and the protection film covers the precut position; cutting is conducted at the precut position to form a cut; the protection film is removed, and the surface of the flexible substrate body is exposed; a structure film layer is produced on the surface of the flexible substrate body. It is unnecessary to add other production processes and conduct other processing operation on the cut, and thus the problem is effectively solved that in traditional technologies, burrsexist at the cut; after precutting, the protection film is removed, contamination caused by cutting chippings on the flexible substrate body can be effectively prevented, the process of washing a cutting line is omitted, technical production processes are reduced, the production time is saved, the product yield of a whole production procedure is increased, and the production efficiency of the whole production procedure is improved.

The invention provides a foaming-assisted sheet metal laser precision boring method. The method includes: (1) mounting a sheet metal workpiece on a machining base plate, coating with a layer of high-temperature foaming agent between the sheet metal workpiece and the machining base plate, and covering the upper surface of the sheet metal workpiece with a sealed suction hood; (2) sucking air outwards through the suction hood to enable the sealed suction hood to be always kept in a negative-state internally; (3) outputting a laser boring pulse through a laser device; (4) keeping a laser beam to continue irradiating for 1ms-500ms, and then ending the laser boring pulse; (5) moving a focus position of the laser beam to a next position needing boring, and repeating the steps (3) and (4) till all holes are machined; (6) after all the holes are machined, taking down the workpiece. Since the method is adopted for laser boring, good hole roundness, no burr at edges of outlets and small hole diameter deviation between hole inlets and the outlets can be guaranteed. The invention further provides a foaming-assisted sheet metal laser precision boring device.

The invention discloses a serging method for a warp-knitted spacer fabric, which relates to a serging technique for a fabric article and provides the serging method for the warp-knitted spacer fabric and a serging device for the warp-knitted spacer fabric. The covering device thereof is provided with two sets of sewing-machine folders. The first sewing-machine folder is provided with a fixing bracket, upper and lower ribbon slots, a zipper locating slot and upper and lower belt guides. The second sewing-machine folder is provided with a fixing bracket, a directing plate, a U-shaped pulling plate and a belt guide. The first sewing-machine folder is arranged on a sewing machine; one half of a zipper is fixed in the zipper locating slot and two ribbons are installed in the upper and lower ribbon slots; then the sewing machine sews one half of the zipper and the two ribbons together to obtain an edge-covered ribbon with one half of the zipper; the second sewing-machine folder is arranged on the sewing machine; the edge-covered ribbon with one half of the zipper is arranged into the second sewing-machine folder and pulled out through the belt guide; the core material of the warp-knitted spacer fabric is clung to the U-shaped pulling plate and the internal wall of the directing plate. The serging is finished under the traction of the sewing machine.

The invention belongs to the punch processing area, which especially relates to a method and specific terrace die for eliminating the burr of through hole at the bottom of cylinder work-piece. The inventive method comprises: using the specific terrace die to extrude a round groove with certain taper at the bottom of cylinder work-piece, while the open of said groove and the bottom of said cylinder chamber are arc transition; and processing a through hole which is through with said round groove at the bottom of said cylinder work-piece, while the diameter of the open of said round groove is larger 5-25% of the diameter of the hole processed by cutting process. The invention utilizes terrace die to eliminate the burr of through hole at the bottom of cylinder work-piece, which can reduce the process of removing burr with high producing efficiency and lower cost.

The invention provides a wind generating set blade inner reinforcing preparation method and a wind generating set blade. The wind generating set blade inner reinforcing preparation method comprises the following steps: laying a first vacuum film on a mold; paving a material for forming an blade inner reinforcing on the first vacuum film; laying a second vacuum film on the material for forming theblade inner reinforcing; sealing the second vacuum film on the mold; vacuumizing for the first time to form a first prefabricated part; attaching the first prefabricated part to the inner surface of ablade to be reinforced, wherein the second vacuum film is located between the blade to be reinforced and the first prefabricated part; removing the second vacuum film; sealing the first vacuum film on the inner surface; vacuumizing for the second time; pouring resin into the material for forming the blade inner reinforcing by adopting a vacuum pouring method, and heating and curing to form the blade inner reinforcing. The preparation method disclosed by the invention has the advantages of ensuring the product quality, improving the production efficiency and the like.
