[0054] With reference to Figure 5 The abutting anvil 65 is arranged on the side wall of the material pulling arm 63, and the abutting anvil 65 can move synchronously with the material pulling arm 63. The side wall of the abutting anvil 65 abuts against the carrier 42 to ensure that when the material pulling arm 63 drives the carrier 42 to move, the carrier 42 can move along the direction of the side wall of the abutting anvil 65, so that the movement track of the carrier 42 is a straight line, thereby improving the processing accuracy.

[0055] With reference to Figure 5 The conveying line 3 is provided with a welding device 7 above for welding chips on the circuit board. In the embodiment, the welding gun of the welding device 7 can move in three directions of X, Y and Z, so that the circuit board on the surface of the conveying line 3 can be soldered, and the degree of automation is high.

[0056] With reference to Figure 5 The conveying line 3 is provided with two lifting cylinders 31 on one side, and the two lifting cylinders 31 are symmetrically arranged about the welding device 7. The piston rod of the lifting cylinder 31 moves in the vertical direction, and the end wall of the piston rod of the lifting cylinder 31 is connected with a supporting rod 32 through bolts. The supporting rod 32 is arranged in the horizontal direction, and the end wall of the supporting rod 32 is connected with a pressing block 33 through bolts. Through the movement of the lifting cylinder 31, the pressing block 33 can abut against the surface of the circuit board, so that the circuit board can be kept stable when the welding device 7 works, thereby improving the processing accuracy.

[0057] The implementation principle of the circuit board loading device of the optical module is as follows: the circuit board loaded with chips on the surface is installed into the carrier 42, and a plurality of carriers 42 are sequentially and slidably inserted into the limiting slide 411 of the material box 4. The material box 4 that has completed loading is placed into the material bin 2, and the transmission belt 22 in the material bin 2 moves the material box 4 towards the direction of the material taking assembly 5 until the material box 4 abuts against the stop block 21.

[0058] After the adjustment of the sliding rail 51, the adjusting cylinder 53, the pneumatic module 54 and the driving screw rod 62, the driving table 55 and the clamping arm 58 on the adjusting block 56 can abut against the lower surface and the upper surface of the material box 4, so as to clamp the material box 4 between the clamping arms 58 on both sides. At this time, the material box 4 is attracted by the magnetic block 59, and the sliding opening 412 thereof can face the material conveying groove 91 of the baffle. The material taking assembly 5 is started again, drives the material box 4 to abut against the baffle, and keeps one of the carriers 42 facing the material conveying groove 91. At this time, the material pulling mechanism 6 is started, pulls the carrier 42 out of the material box 4, and transports the carrier 42 along the length direction of the conveying line 3. When the carrier 42 moves to the lower side of the welding device 7, the welding device 7 welds and fixes the circuit board and the chip on the surface of the circuit board. With the start of the carrier 42, the material taking assembly 5 drives the material box 4 to adjust the position, so that the material pulling mechanism 6 can pull all the carriers 42 out of the material box 4. The tools with high automation capacity, such as the material taking assembly 5, the material pulling mechanism 6, the conveying line 3 and the welding device 7, are arranged to replace the manual work, improve the continuous soldering capacity of the circuit board, save the working time, reduce the failure rate, and improve the overall production efficiency.

[0059] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
