In addition, there are about 7 types of heat sinks and filters used in one optical module (4*4*2, 5*5*0.5, 9.5*5*0.5, 11*11*1, 12*14*1, 13*1.1*0.75, 15*7*2), and the number of patches required is about 9. Manual operation is difficult. At present, the patch process of one module requires 3 people to complete, and each person is responsible for 2-3 types of heat sinks. , requiring more manpower; (2) The patch position is mainly determined by the naked eye and experience, and there is a problem of rework due to unqualified labeling position; (3) New employees do not control the force properly when clamping the heat sink with tweezers, resulting in many problems of scrapped materials; (4) The entire process requires continuous manual operation, which consumes a long time and has a low labor time utilization rate; (5) Due to the softness of the heat sink material and the control of material costs, the heat sink incoming material is distributed without gaps in the front, back, left and right. The conventional sheet material auxiliary feeding equipment on the market cannot meet the use requirements. In addition, due to the high viscosity between the heat sink and the base paper, the method of directly sucking the heat sink from the base paper on the market is not applicable.

[0029] Specifically, in this embodiment, six groups of alignment and positioning units 3 are provided on the fixed material box 2 for respectively fixing six different types of flaky heat sinks, which can meet all specifications of flaky heat sinks required by existing optical modules.

[0030] As a specific implementation method, Figure 2 , Figure 3 and Figure 4 As shown, the alignment and positioning unit 3 includes a unit material box 5, a pressure cover 7 and a base 6.
