This invention relates to a method for getting wafers thinner including: providing a wafer with an active side and a back, setting several hump elements on the active side and putting the wafer in a die and forming a macromolecular material in the die to cover the active side of the wafer at least, solidifying the macromolecular material and removing the die, grinding the back of the wafer to get the wafer thinner, finally, removing the material to expose the active side of the wafer and the hump elements on it, which utilizes the die to enable the macromolecular material to cover the active side of the wafer and wrap the hump elements, in this way, stress generated in grinding the wafer is distributed on the wafer uniformly so as to avoid warp, break, crack of the wafer or peel off of the hump elements.

The base plate transfer device includes one pedestal; one rotation shaft unit with one support shaft and one rotation shaft seat fixed on the pedestal and pivoted with the support shaft to support the support shaft and control the rotation of the support shaft; and one base plate bearing unit fixed to the other end of the support shaft and including one bearing base connected to the support shaft, several bearing elements on the surface of the bearing base, one top bearing base on one side of the bearing elements and at least one telescopic element. The top bearing base has several vacuum sucking nozzles for sucking and detecting the base plate; the telescopic element is for regulating the interval between the top bearing base and the bearing base; and the rotation shaft seat controls the inclination of the base plate bearing unit indirectly. The present invention can detect the fault in base plate, correct the position of the base plate and convey base plate in inclined mode.

The invention discloses a mechanical arm. The mechanical arm comprises a moving arm, a first adsorption device and a second adsorption device. The moving arm is horizontally arranged and moves in the horizontal direction or vertical direction to be away from or close to a first object to be adsorbed, and the first object is in tight contact with a panel; the first adsorption device is fixedly arranged on the moving arm and used for adsorbing the non-edge of the first object in contact with the first adsorption device under the vacuum effect; and the second adsorption device is movably arranged on the edge position of the moving arm, can vertically move in the vertical direction, is used for adsorbing the edge of the first object in contact with the second adsorption device under the vacuum effect, and can vertically move to enable the edge of the first object to be adsorbed, so that the edge of the first object is separated from the panel. Through the manner, adhesive force between the first object and the panel can be reduced, and it is ensured that the first object and the panel are separated very easily.

A storage box includes a box body, two door leaves, a fixed frame, a handle portion and two pairs of gears, wherein the box body has an accommodating space, of which the inner wall is provided with a plurality of slots for accommodating base materials, and each door leaf has an opening for a door shaft to be pivoted into the accommodating space. The handle portion includes a first U-shaped member, a second U-shaped member and a handle, wherein both ends of the first U-shaped member are respectively pivoted onto the fixed frame and are near the opening of the accommodating space, both ends of the second U-shaped member are respectively pivoted onto the fixed frame, and both ends of the handle are respectively pivoted onto the first U-shaped member and the second U-shaped member. Each pair of gears has two gear assemblies respectively situated at the end of the door shaft and the end of the first U-shaped member. Two gear assemblies are orthogonally connected, so that the two door leaves are driven to rotate when the first U-shaped member is rotated.

This invention relates to an anti-explosion blanket. The anti-explosion rail is covered with anti-explosion blanket. The anti-explosion rail is through-hole cylinder structure. The bottom of the said anti-explosion rail is covered with leak protection rail. The said anti-explosion rail moves in axial direction inside of the leak protection rail and is limited by connecting belt. One end of the said connecting belt connects to the leak protection rail. The other end connects to the anti-explosion rail. Unloading gaps are opened in the middle of the said anti-explosion blanket. One end of all the unloading gaps lead to the center of the blanket and are bonded together through connecting round buckle. The other end of all the said unloading gaps open out and form irradiation structure. This invention is convenient and has strong unloading capability. It has good protection effect in close distance.

The invention provides a display module and an assembling method thereof. The display module comprises a display panel, a front frame and a first polarizer film, wherein the display panel comprises afirst base plate and a second base plate which are arranged oppositely; the front frame is arranged at one side of the first base plate corresponding to the second base plate and is provided with a first surface and a second surface which are arranged oppositely, and the second surface of the front frame faces the display panel; and the first polarizer film is fixedly arranged on the front frame and is provided with a third surface and a fourth surface which are arranged oppositely, and the third surface faces the display panel.

The invention is used in rotating a cartridge, and then fixing it. It consists of: a rotating unit located at one side of the cartridge used in rotating the cartridge; a base; movable locating unit containing a locating unit and a rolling component located at one side of rotated cartridge, and the locating component and rolling component are fixed on the base; the rolling component is pops out from the place between locating component and cartridge, used in providing positioning in vertical direction for the rotated cartridge; the location component provides the positioning in horizontal direction for the rotated cartridge.

The invention discloses a corrosion method for germanium substrate sheet of solar battery, comprising the following steps of: preparing No.1 corrosion liquid medicine by 1200-1300ml of pure water and 140-150ml of hydrofluoric acid with mass concentration of 48-50%, orderly placing the germanium sheet in a clamping plug, showering the clamping plug with the pure water and then dipping the clamping plug into the No.1 corrosion liquid medicine, shaking the clamping plug, after corroding the germanium sheet for 7-10 seconds, taking out the germanium sheet, quickly placing the germanium sheet into a pure water tank for washing, and showering the germanium sheet with the pure water; preparing a No.2 corrosion liquid medicine by 150-160ml of glacial acetic acid with mass concentration of not less than 99.7%, 3-5ml of bromine water with mass concentration of 99.5% and 250-260ml of hydrogen nitrate with mass concentration of 98%; dipping the clamping plug with the germanium sheet into the No.2 corrosion liquid medicine, shaking the clamping plug, taking out the germanium sheet after corroding for 20-30 seconds, placing the germanium sheet into the pure water tank for washing, showering the germanium sheet with the pure water, and finally, placing the clamping plug and the germanium sheet into a flowing water tank. By corrosion according to the method provided by the invention, the strength of the germanium sheet is enhanced, the strength is more than 18bf, and the breakage rate of the germanium sheet is greatly reduced.
