It is not satisfactory in terms of detection speed, efficiency and cost control, bringing difficulties to the large-scale integrated production of enterprises. Therefore, it is necessary to design a PCB board testing device to solve the above problems. Content of the Utility Model

[0022] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions 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] The present invention provides the following embodiments:

[0024] A PCB board detection device includes a manipulator 3 for grasping a PCB board 4. On one side of the manipulator 3, there is a detection platform 1. On the detection platform 1, there are two sets of detection mechanisms 2 that are centrosymmetric. The two sets of detection mechanisms 2 have the same structure. The detection mechanism 2 includes a clamping component 21 for fixing the PCB board 4 and a driving component 22 for detecting the PCB board 4. By setting two sets of detection mechanisms 2 that cooperate with the manipulator 3, the manipulator 3 drives the PCB board 4 to reach the detection mechanism 2, the clamping component 21 clamps the PCB board 4, and then the driving component 22 approaches the PCB board 4. The driving component 22 abuts against the PCB board 4 to detect the PCB board 4, improving the detection efficiency and detection accuracy of the PCB board 4.

[0025] The clamping component 21 includes a placement table 211 fixedly connected to the detection platform 1. On one side of the placement table 211 close to or away from the manipulator 3, there is a support block 212. On the side of the support block 212 close to the placement table 211, a connecting plate 214 is slidably connected through a first module 213. A positioning plate 215 is fixed on the connecting plate 214. On the placement table 211, there is a placement plate 16. On the placement plate 16, there are several transition blocks 2161 that abut against the bumps 41 of the PCB board 4. At the bottom end of the positioning plate 215, there is a positioning column 217. The bottom end of the positioning column 217 abuts against the placement plate 16. The first module 213 drives the positioning plate 215 to rise, the robotic arm drives the PCB board 4 to be placed on the placement plate 16, and the first module 213 drives the positioning plate 215 to descend until the positioning column 217 abuts against the placement plate 16. At this time, the transition blocks 2161 and the bumps 41 abut against each other.

[0026] The driving component 22 is arranged on the detection platform 1 on the side close to the transition block 2161. The driving component 22 includes a second module 221 fixedly connected to the detection platform 1. The output end of the second module 221 is fixed with a connecting block 222. On the connecting block 222, there are several groups of detection pieces 223. The second module 221 drives the detection pieces 223 to approach the placement table 211 until the detection pieces 223 abut against the transition block 2161, which is equivalent to the detection pieces 223 being connected to the bumps 41 to detect the PCB board 4.

[0027] A reinforcing rib 218 is fixed between the top end of the positioning plate 215 and the connecting plate 214. The reinforcing rib 218 helps to fix between the positioning plate 215 and the connecting plate 214.

[0028] A slide rail 11 and a driving cylinder 12 are provided on the detection platform 1. A slider 2121 is fixed to the bottom end of the support block 212. The slider 2121 is slidably connected to the slide rail 11. A screw rod 13 is provided at the output end of the driving cylinder. The support block 212 is threadedly connected to the screw rod 13. The driving cylinder drives the support block 212 to slide to adjust the distance between the positioning plate 215 and the placement table 211, preventing deviation of the positioning plate 215.
