On the other hand, the second inspection station 120 is adjacent to the first inspection station 110, and the second inspection station 120 includes a second camera 122, wherein the rotating pin device 112 rotates about the first axis a1 and conveys the workpiece 10 to the second inspection station 120, and the second camera 122 is used to inspect the second face 10b of the workpiece 10 to obtain a second image. The second side 10b of the workpiece 10 may be opposite the first side 10 a. It should be noted that, in the present embodiment, the workpiece 10 may be transferred in the direction of the arrow shown in fig. 1, however, the present invention is not limited thereto. Further, the workpiece 10 may be a hollow workpiece having a hole, such as a sleeve, a washer, a nut, a box or a box having a hole, but the present invention is not limited thereto, and the workpiece 10 may be any suitable workpiece requiring surface inspection.
The first camera 114 and the second camera 122 are, for example, infrared image capturing devices, for example, the first camera 114 and the second camera 122 are, for example, line scan cameras or area scan cameras. Further, the first image and the second image of the workpiece 10 may be transmitted to the inspection module 130 for surface inspection, wherein the inspection module 130 is electrically connected to the first camera 114 and the second camera 122, but the invention is not limited thereto, and the combination of the first camera 114, the second camera 122 and the inspection module 130 may be any other device suitable for having a surface inspection function.
The detection module 130 is, for example, a Central Processing Unit (CPU), other Programmable general purpose or special purpose microprocessor (microprocessor), a Digital Signal Processor (DSP), a Programmable controller, an Application Specific Integrated Circuit (ASIC), a Programmable Logic Device (PLD), other similar Processing devices, or a combination thereof, and may be embedded in or externally connected to a memory, but the invention is not limited thereto.
In the present embodiment, the workpiece inspection system 100 can obtain images of different surfaces of the workpiece 10 by the first camera 114 and the second camera 122 through the configuration of the first inspection station 110 and the second inspection station 120, and then obtain corresponding surface inspection results through the inspection module 130. Furthermore, the workpiece 10 can be picked up by rotating the needle device 112 without using a manual or robot, thereby reducing the difficulty of picking up the workpiece 10. In addition, the workpiece 10 can be turned rapidly by rotating the rotary needle device 112 to drive the workpiece 10, so as to increase the turning speed, and therefore, the workpiece inspection system 100 of the embodiment can achieve a comprehensive surface inspection of the workpiece 10 and can effectively improve the inspection efficiency of the workpiece 10.
