Problems solved by technology

[0004] First, the accumulation of operator fatigue will lead to the inability of operators to inspect bad boards stably for a long time, which will easily cause bad outflows;
[0005] Second, there is a stress welding place in the board card during the process of being held by the operator, which has an adverse effect on the welding reliability;
[0006] Third, in order to facilitate visual inspection, it is often necessary to rotate the board to adjust the viewing angle, which is prone to hidden dangers such as collisions and electrostatic damage

Embodiment 1

[0025] A method for designing a load-carrying jig for inspection of large-sized boards, said method fixes a board to be inspected by setting a board carrier 1, and sets the board carrier 1 on the board support column 2 On the workbench: by setting the rotating device, the board carrier 1 can be rotated in the horizontal direction, which is convenient for inspectors to adjust the viewing angle during inspection.

[0026] The method content also includes:

[0027] The carrier board support column 2 is provided with a steering device 4, which can make the carrier board support column 2 adjust the angle in the vertical direction. By setting the steering device 4 in the vertical direction, the position and angle of the board card carrier board 1 can be further adjusted to facilitate Inspectors observe.

[0028] The method also includes:

[0029] The carrier support column 2 is set on the worktable through the jig base 5 . By arranging a carrier base 5, on the one hand, the jig c...

Embodiment 2

[0031] Such as figure 1 As shown, a load-bearing jig structure for large-scale board inspection, the structure of the jig includes a board carrier 1, a carrier support column 2, and a carrier rotating disk 3, wherein the carrier rotating disk 3 is set Between the board carrier 1 and the carrier support column 2 , the board carrier 1 can be rotated by the carrier rotating disk 3 .

[0032] The support column 2 of the carrier board is divided into two parts, and a steering device 4 is arranged between the two parts. The purpose of designing the steering device 4 is to adjust the horizontal angle of the carrier board when the carrier board faces the operator. Perspective change.

[0033] The structure of the jig also includes a carrier base 5 , and the board carrier 1 is arranged on the carrier base 5 through the carrier support column 2 .

[0034] The steering device 4 provided between the two parts of the carrier support column 2 is a rotating shaft with damping, which can fi...

Abstract

The invention discloses a design method and structure of a bearing jig for checking a large-size plate card. The method comprises the following steps: arranging a plate card bearing plate to fix a plate card to be checked; arranging the plate card bearing plate on a worktable through a carrying plate supporting column; arranging a rotary device to enable the plate card bearing plate to rotate in the horizontal direction. By adopting the design method and structure, disclosed by the invention, the fatigue accumulation of workers can be reduced, the detection rate of defective plate cards is improved and stabilized and the yield of unit time is increased; a phenomenon that stress acts on a welding part in a process of holding the plate card by the worker and bad influences on the welding reliability are caused is avoided, and hidden dangers that the plate card is rotated in a visual checking process, and part collision and electrostatic damages are easy to generate and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of circuit board processing technology, in particular to a design method and structure of a load-carrying jig for large-scale board card inspection. Background technique [0002] Electronic products need to go through many links from design to product realization, among which electronic product processing is an important link. SMT is Surface Mounted Technology (abbreviation for Surface Mounted Technology), which is the most popular technology and process in the electronic assembly industry. . With the increase in the number of processing and the difficulty of design, the risk of processing quality increases accordingly. In order to control the processing quality of boards and cards, the industry continues to develop and introduce advanced inspection equipment and interception methods. However, in the actual processing process, these inspection equipment and The method still cannot completely replace manual ...
