Fig. 4c is an enlarged view of part B of Fig. 4a; FIG. 4D is an enlarged view of part C of FIG. 4B, showing the coupling of the circuit board 109 with components proximate the first side transfer channel 211 in the clamping process of the circuit board. Since the components close to the second side 402 opposite the first side 401 of the circuit board 109 are similar to the components close to the first side 401 in an almost symmetrical structure, the circuit board 109 The process of clamping is described by taking as an example the coupling between components proximate the first side 401 of the circuit board 109 of FIGS. 4C and 4D. 4C, the inner edge 405 of the lower conveying portion 314 on the first side upper conveyor belt 201.1 and the inner edge 407 of the upper conveying portion on the first side lower conveying conveyor belt 202.1. ) Are staggered with respect to each other. That is, in the horizontal direction shown in FIG. 4C, the inner edge 405 of the first side upper conveyor belt 201.1 is closer to the inner side than the inner edge 407 of the first side lower conveyor belt 202.1, that is, the first 2 close to the side track assembly, and thus 0.5 between the two inner edges, the inner edge 405 of the first side upper conveyor belt 201.1 and the inner edge 407 of the first side lower conveyor belt 202.1 There is a distance (D) of mm to 5 mm. According to some embodiments of the present application, the range of D is from 0.5 mm to 5 mm. In some embodiments of the present application, the distance D is about 2 mm. The clamping plate 321 is located under the first side upper conveyor belt 201.1, whereby the clamping plate 321 is an inner edge of the upper conveying part 318 on the first side lower conveyor belt 202.1 when moving up and down. It may pass 407 and may not exceed the lower transfer portion 314 of the first side upper conveyor belt 201.1. Before the circuit board 109 is clamped, that is, when the clamping plate 321 is in the resting state of the initial position as shown in FIG. 4C, the edge on the first side 401 of the circuit board 109 is the first It is in contact with the upper conveying portion 318 of the side lower conveyor belt 202.1 and is spaced a certain distance from the lower conveying portion 314 of the first side upper conveyor belt 201.1.
