[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-10 As shown, the assembly line circuit board testing device provided in this embodiment includes a support 2, two sets of conveying components 1, a positioning component 3 equipped with a photoelectric sensor 37, multiple sets of carrier plates 4, and a motor 5 equipped with a control circuit board (not shown in the figure). The two sets of conveying components 1 are arranged parallel to each other on both sides of the top of the support 2. The positioning component 3 is fixed on the support 2. The two sides of the carrier plate 4 are respectively placed on the two conveying components 1. The end of the carrier plate 4 is provided with a notch 41. Both sets of conveying components 1 are connected to the motor 5 for transmission. The photoelectric sensor 37 is electrically connected to the control circuit board. Those skilled in the art will understand that when the carrier plate 4 is running on the conveying component 1, when the notch 41 of the carrier plate 4 reaches the photoelectric sensor 37, the photoelectric sensor 37 responds and sends a signal to the control circuit board. The control circuit board controls the motor 5 to stop, thereby stopping the conveying component 1. This ensures that the circuit board on the carrier plate 4 is below the detection device, thereby improving the detection efficiency of the circuit. The photoelectric sensor 37 is prior art and will not be described in detail here.

[0024] Furthermore, the positioning component 3 also includes a first substrate 32, two sets of first fixing blocks 31 and a first connecting block 33; the two sets of first fixing blocks 31 are respectively fixed at both ends of the top of the first substrate 32; the photoelectric sensor 37 is fixed to the top of the first substrate 32 through the first connecting block 33; the first substrate 32 is fixed across the bracket 2 through the two first fixing blocks 31; the photoelectric sensor 37 is close to the bottom of the carrier plate 4.

[0025] Furthermore, the positioning component 3 also includes a telescopic cylinder 36 with a push rod 38 and a first positioning block 34; the first base plate 32 is provided with a shaft hole; the telescopic cylinder 36 is fixed to the bottom of the first base plate 32; the push rod 38 passes through the shaft hole and is fixed to the first positioning block 34; the telescopic cylinder 36 is electrically connected to the control circuit board. Those skilled in the art will understand that when the notch 41 of the support plate 4 moves to the photoelectric sensor 37, the control circuit board simultaneously sends an electrical signal to the telescopic cylinder 36, which pushes out the push rod 38, causing the first positioning block 34 to slide upwards. The first positioning block 34 pushes out from the notch 41 of the support block to block and position the support plate.

[0026] Furthermore, the positioning component 3 also includes a second positioning block 35; the second positioning block 35 is fixed on the first substrate 32 and slidably disposed with respect to the first positioning block 34. Those skilled in the art will understand that the second positioning block 35 can improve the stability of the sliding motion of the first positioning block 34, thereby further improving the positioning accuracy of the first positioning block 34.

[0027] Furthermore, the number of positioning components 3 is multiple sets. Those skilled in the art will understand that this increases the number of inspection stations, thereby improving inspection efficiency. Two positioning components 3 can be combined into a pair, so that the two ends of the support plate can be fixed by two sets of first positioning blocks 34, thereby further improving the positioning accuracy of the support plate.

[0028] Furthermore, the conveying assembly 1 also includes a first conveyor belt 11, a first tensioning roller 12, a second tensioning roller 13, a third tensioning roller 15, and a mounting plate 14; the first tensioning roller 12, the second tensioning roller 13, and the third tensioning roller 15 are all mounted on the mounting plate 14; the mounting plate 14 is fixed to the bracket 2; the first conveyor belt 11 and the motor 5 are connected in a driving connection; the first tensioning roller 12, the second tensioning roller 13, and the third tensioning roller 15 are all slidably disposed with respect to the first conveyor belt 11. Those skilled in the art will understand that by adjusting the first tensioning roller 12, the second tensioning roller 13, and the third tensioning roller 15, the transmission effect of the first conveyor belt 11 can be improved.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
