The detection mechanism is located at the outer end of the main body mechanism, and the auxiliary mechanism is located at the lower end of the main body mechanism. The main body mechanism includes a detection table, a support rod, a limit groove, a rear support seat, a front support seat and a control panel. The support rod is fixedly installed at the lower end of the detection table. For this circuit board detection device, through the parameter adjustment of the control panel, the rotational detection of the detection camera can be positioned directly above the limit groove each time, facilitating the adjustment of the detection camera to the closest position above the circuit board for shooting, facilitating the taking of complete and clear pictures of the circuit board, improving the practicability of the device. The taken pictures are transmitted to an external processor through the control panel to analyze the soldering condition of the circuit board, thus eliminating the deficiencies of manual detection and improving the practicability of the device.

[0004] The above patent has the following problems:

[0005] After the circuit board detection is completed, it is necessary to first pause the shooting of the camera, replace the detected circuit board, and then continue the detection, which reduces the detection efficiency. Therefore, we have introduced a detection device for bare circuit boards. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0024] A detection device for a bare circuit board, comprising a workbench 2. A support box 7 is fixedly arranged at the upper end of the workbench 2. There is an opening on the front side of the support box 7. A detection camera 1 is fixedly installed on the top of the support box 7. A displacement mechanism is arranged on the detection camera 1. The detection camera 1 can be driven to displace through the displacement mechanism, so as to detect the bare circuit boards in a plurality of placement grooves 5. Below the detection camera 1, there are an upper slide plate 4 and a lower slide plate 8. A plurality of placement grooves 5 are arranged on the tops of the upper slide plate 4 and the lower slide plate 8. Strip-shaped grooves are opened on the inner side walls of the support box 7 at the positions of the upper slide plate 4 and the lower slide plate 8. Push rods 3 are fixedly arranged on the sides of the upper slide plate 4 and the lower slide plate 8 away from the magnet 11. The push rods 3 are U-shaped, and the push rods 3 are convenient for staff to pull the upper slide plate 4 or the lower slide plate 8.

[0025] A sliding mechanism is arranged between the side walls of the upper slide plate 4 and the lower slide plate 8 and the strip-shaped grooves. The sliding mechanism comprises sliding rods 6. The sliding rods 6 are fixedly arranged in the strip-shaped grooves, and the sliding rods 6 are horizontally arranged. Sliders 10 are fixedly arranged on the side walls of the upper slide plate 4 and the lower slide plate 8. The sliders 10 are slidably connected with the rod walls of the sliding rods 6. The sliders 10 are located on the sides of the side walls of the upper slide plate 4 and the lower slide plate 8 close to the magnet 11.

[0026] A linkage unit capable of pushing in the reverse direction is arranged between the upper slide plate 4 and the lower slide plate 8. The linkage unit comprises a rotating shaft 13 and a gear 14. The rotating shaft 13 is arranged between the upper slide plate 4 and the lower slide plate 8, and both ends of the rotating shaft 13 are rotatably connected with the support box 7 through rolling bearings. The gear 14 is fixedly arranged on the rotating shaft 13. Rack bars 12 meshing with the gear 14 are fixedly arranged on the sides of the upper slide plate 4 and the lower slide plate 8 close to each other. The two rack bars 12 are centrosymmetric with the rotating shaft 13 as the center.

[0027] Magnets 11 are fixedly arranged on the inner side walls of the support box 7 at the positions of the upper slide plate 4 and the lower slide plate 8. Metal blocks 9 are fixedly arranged at the positions corresponding to the magnets 11 on the side walls of the upper slide plate 4 and the lower slide plate 8.

[0028] Anti-slip blocks are fixedly arranged at the four corners of the bottom of the workbench 2. The anti-slip blocks are wear-resistant rubber blocks. The anti-slip blocks can increase the friction between the bottom of the workbench 2 and the ground, and can reduce the probability of the workbench rotating when the staff pulls the push rod.

[0029] Through holes are arranged at the bottom of the placement grooves 5. By inserting fingers from the bottom up into the through holes, it is convenient to take out the bare circuit boards in the placement grooves 5.

[0030] During use, if multiple circuit bare boards are respectively placed into the multiple placement slots 5 of the upper slide plate 4, push the push rod 3 of the upper slide plate. The push rod 3 drives the upper slide plate 4 to move and drives the multiple circuit bare boards to move into the interior of the support box 7. While the upper slide plate 4 is moving into the interior of the support box 7, the lower slide plate 8 is driven to move outside the support box 7 through the gear 14 and the rack 12. When the metal block 9 is attracted to the magnet 11, the upper slide plate 4 and the lower slide plate 8 are limited in position. At this time, turn on the detection camera 1, and the detection camera 1 sequentially detects the multiple circuit bare boards. When the detection camera 1 is detecting, the lower slide plate 8 is located outside the support box 7. At this time, the staff can place the multiple circuit bare boards into the placement slots 5 of the lower slide plate 8. When the detection by the detection camera 1 is completed, pull out the upper slide plate 4. While pulling out the upper slide plate 4, the lower slide plate 8 is driven to slide in through the linkage unit. The detection camera 1 can immediately detect the circuit bare boards on the lower slide plate 8. By alternately sliding in the upper slide plate 4 and the lower slide plate 8, feeding and discharging can be carried out while the detection camera 1 is detecting, greatly improving the detection efficiency.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
