Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board detection, and particularly relates to a forming detection device for a printed circuit board without positioning pin holes. Background Technique

[0002] The printed circuit board without positioning pin holes is a special circuit board manufacturing process, and its main feature is that traditional positioning pin holes are not used for positioning during the manufacturing process. The forming detection of the printed circuit board without positioning pin holes is an important link to ensure its quality. Through means such as appearance inspection, dimension inspection, electrical performance testing, and advanced detection methods, the quality of the circuit board can be comprehensively evaluated. When performing an appearance inspection on a printed circuit board without positioning pin holes, a visual detection device is required.

[0003] In the existing patent application with the application number CN202322690727.4, a visual detection device for a printed circuit board is proposed. Although it can effectively realize the function of turning over the printed circuit board, thereby realizing the double-sided visual detection of the printed circuit board, due to the lack of components for limiting and fixing the printed circuit board without positioning pin holes on its conveyor belt, when the printed circuit board without positioning pin holes is placed on the conveyor belt for transportation, it is easy to be placed obliquely, so that it cannot effectively pass through the detection range of the visual detection camera. At the same time, when the printed circuit board without positioning pin holes is transported on the conveyor belt, it is prone to move under external force, which will further cause the printed circuit board without positioning pin holes to not be effectively identified and detected by the visual detection camera, and ultimately reduce the efficiency of the forming detection of the printed circuit board without positioning pin holes. Therefore, it needs to be improved. Content of the Utility Model

[0004] The embodiment of the utility model provides a forming detection device for a printed circuit board without positioning pin holes, aiming to solve the problem that when the existing printed circuit board without positioning pin holes is placed on the conveyor belt for transportation, it is easy to be placed obliquely, so that it cannot effectively pass through the detection range of the visual detection camera. At the same time, when the printed circuit board without positioning pin holes is transported on the conveyor belt, it is prone to move under external force, which will further cause the printed circuit board without positioning pin holes to not be effectively identified and detected by the visual detection camera, and ultimately reduce the efficiency of the forming detection of the printed circuit board without positioning pin holes.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown in the figures, a forming detection device for a printed circuit board without positioning pin holes includes a belt conveyor 1. A bracket 5 is fixedly installed at the lower end of the belt conveyor 1, and a gantry 6 is fixedly installed at the upper end of the belt conveyor 1. A vision detection camera 7 is fixedly installed on the gantry 6.

[0023] A number of mounting brackets 2 are fixedly installed on the conveyor belt of the belt conveyor 1 in pairs symmetrically. The mounting bracket 2 is composed of a mounting plate 8, a mounting guide rod 9, and an anti - detachment baffle 10. The mounting guide rod 9 is fixedly installed at the front end of the mounting plate 8, and the anti - detachment baffle 10 is fixedly installed at the front end of the mounting guide rod 9. The mounting plate 8 on the mounting bracket 2 is fixedly installed on the conveyor belt of the belt conveyor 1. A first hole 11 is opened on the mounting plate 8, and the first hole 11 penetrates the mounting plate 8 inside and outside.

[0024] A clamping structure 3 is movably installed on the mounting plate 8. The clamping structure 3 is composed of a mounting rod 12, a return spring 13, a rigid support plate 14, a rubber pad 15, and a contact block 16. The return spring 13 is sleeved on the mounting rod 12. The rigid support plate 14 is fixedly installed at the inner end of the mounting rod 12. The rubber pad 15 is fixedly installed at the inner end of the rigid support plate 14. The contact block 16 is fixedly installed at the outer end of the mounting rod 12. The mounting rod 12 on the clamping structure 3 is slidably installed in the first hole 11 opened on the mounting plate 8. The rigid support plate 14 is located inside the mounting plate 8, and the return spring 13 is located outside the mounting plate 8.

[0025] A limiting structure 4 is slidably mounted on two symmetrically arranged mounting brackets 2. The limiting structure 4 is composed of a connecting rod 17 and limiting rods 20. There are two limiting rods 20 which are symmetrically and fixedly mounted at the rear end of the connecting rod 17. The limiting rods 20 on the limiting structure 4 can contact the contact blocks 16 on the clamping structure 3. Two receiving grooves 18 are symmetrically formed at the front end of the connecting rod 17, and two second holes 19 are symmetrically formed at the rear end of the connecting rod 17, and the receiving grooves 18 and the second holes 19 communicate with each other. The connecting rod 17 is slidably mounted on the anti-detachment baffle 10 and the mounting guide rod 9 through the receiving grooves 18 and the second holes 19 formed thereon. By arranging the mounting brackets 2 on the conveyor belt of the belt conveyor 1, arranging the clamping structure 3 on the mounting brackets 2, and simultaneously arranging the limiting structure 4 on the mounting brackets 2, the printed circuit board without positioning pin holes to be detected can be fixed on the conveyor belt of the belt conveyor 1, so that the printed circuit board without positioning pin holes will not be placed obliquely, and when the printed circuit board without positioning pin holes is conveyed by the belt conveyor 1, it is not easy to move under external force. Furthermore, the printed circuit board without positioning pin holes can effectively pass through the detection range of the vision detection camera 7, and finally the printed circuit board without positioning pin holes can be effectively and quickly detected, thereby improving the efficiency of the forming detection of the printed circuit board without positioning pin holes.

[0026] It should be noted that the present invention is a forming detection device for a printed circuit board without positioning pin holes. When performing forming detection on the printed circuit board without positioning pin holes, the circuit board to be detected can be placed on the conveyor belt of the belt conveyor 1, and at the same time, the circuit board is located between two adjacent clamping structures 3. Then, the limiting structure 4 can be pushed backward, so that the limiting structure 4 slides backward on the anti-detachment baffle 10 and the mounting guide rod 9 on the mounting bracket 2. At this time, the limiting rods 20 will squeeze the contact blocks 16 on the clamping structure 3. Furthermore, the contact blocks 16, the mounting rods 12, the rigid support plates 14, and the rubber pads 15 will move inward. At this time, the return spring 13 will be compressed by the contact blocks 16. When the clamping structure 3 is completely inside the limiting rods 20, the two adjacent clamping structures 3 will clamp and fix the circuit board. Then, as the conveyor belt on the belt conveyor 1 moves, the circuit board will pass under the vision detection camera 7. At this time, the vision detection camera 7 will detect the circuit board; when the circuit board is detected, the limiting structure 4 can be pulled forward, and then under the elastic force of the return spring 13, the contact blocks 16, the mounting rods 12, the rigid support plates 14, and the rubber pads 15 will move outward. At this time, the fixation of the circuit board is released, and then the circuit board can be removed from the conveyor belt.
