Therefore, by fixing a plurality of loading mechanisms 23 on the rotating disk 21 at equal intervals in the circumferential direction, the rotation of the rotating disk 21 drives the loading mechanisms 23 to rotate, so that different loading mechanisms 23 correspond to the vision camera module 3. While improving the detection efficiency, it also ensures that the vision camera module 3 is directly opposite to the circuit board to be detected, ensuring the detection accuracy.

[0041] Specifically, as shown by Figures 1-3 , the loading mechanism 23 includes: a bottom plate 231 and a tray 232. The bottom plate 231 is fixed on the rotating disk 21, the tray 232 is placed on the bottom plate 231, and a stepped groove 2321 is formed in the tray 232 for placing the circuit board to be detected. The tray 232 is placed on the bottom plate 231, which has the characteristic of being easy to install and disassemble, facilitating the replacement of different trays 232 according to different circuit boards.

[0042] Preferably, as shown by Figures 1-3 , in this embodiment, it further includes: a first magnetic sheet 233 and a second magnetic sheet 234. The first magnetic sheet 233 is fixed on the top surface of the bottom plate 231, and the second magnetic sheet 234 is fixed on the bottom surface of the tray 232 and attracted to the first magnetic sheet 233. After the tray 232 is placed on the bottom plate 231, the first magnetic sheet 233 and the second magnetic sheet 234 are attracted to each other, ensuring the stability of the placement of the tray 232.

[0043] Preferably, as shown by Figures 1-3 , in this embodiment, it further includes: a positioning block 2323. The positioning block 2323 is fixed on the bottom surface of the tray 232, and a positioning groove 2311 for the positioning block 2323 to be embedded is formed on the top surface of the bottom plate 231. After the tray 232 is placed on the bottom plate 231, the positioning block 2323 is embedded in the positioning groove 2311 to position the placement position of the tray 232, ensuring the accuracy of the placement position of the tray 232, so as to facilitate the vision camera module 3 to be directly opposite to the circuit board to be detected.

[0044] Optionally, as shown by Figures 1-3 , in this embodiment, a disassembly and assembly groove 2322 is formed at the top end of the tray 232, and it is easy to take and place the circuit board through the disassembly and assembly groove 2322.

[0045] Optionally, as shown by Figure 1 and Figure 4 In this embodiment, the vision camera module 3 includes: a lifting plate 31, a CCD camera 33, and a light source 34. The lifting plate 31 is movably arranged on the machine body 1 and can move freely in the vertical direction. The CCD camera 33 is fixed on the lifting plate 31 by a fixing bracket 32. The light source 34 is fixed on the lifting plate 31 and is located directly below the CCD camera 33. The CCD camera 33 can clearly collect the appearance image of the circuit board with the help of the light source 34 and transmit the image information to the image processing system for detection.

[0046] Optionally, as shown by Figure 1 and Figure 4 In this embodiment, the vision camera module 3 further includes: a top plate 35, a threaded column 37, and a second servo motor 38. The top plate 35 is supported and fixed on the machine body 1 by a support column 36. The threaded column 37 is rotatably installed between the machine body 1 and the top plate 35, and the threaded column 37 passes through the lifting plate 31 and is connected to the lifting plate 31 in a threaded engagement manner. The second servo motor 38 is fixed on the top plate 35 and is used to drive the threaded column 37 to rotate. By starting the second servo motor 38 to drive the threaded column 37 to rotate, under the action of the threaded engagement, the lifting plate 31 drives the CCD camera 33 and the light source 34 to lift, adjusts the heights of the CCD camera 33 and the light source 34, and adjusts the distance between the CCD camera 33 and the light source 34 and the circuit board to ensure the detection accuracy.

[0047] Preferably, as shown by Figure 1 and Figure 4 In this embodiment, there are two symmetrically distributed support columns 36, and the support columns 36 pass through the lifting plate 31 to ensure the stability of the top plate 35, and the support columns 36 are also used to guide the lifting plate 31 to improve the stability of the lifting plate 31.

[0048] It should be noted that the first servo motor 22, the CCD camera 33, the light source 34, and the second servo motor 38 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to the usage needs. Their working principles are common knowledge well-known to those skilled in the art and have been fully disclosed by the prior art, so no more details will be described herein.

[0049] The circuit connection involved in the present utility model is a common means adopted by those skilled in the art and can obtain technical inspiration through a limited number of experiments, belonging to the prior art widely used.

[0050] The components not described in detail herein are prior art.

[0051] Working principle and usage process of the present utility model: For the detection platform of the present utility model, during use, a tray 232 of a suitable specification is placed on the bottom plate 231, and the positioning block 2323 is inserted into the positioning groove 2311 to position the placement position of the tray 232, ensuring the accuracy of the placement position of the tray 232. At this time, the first magnetic sheet 233 and the second magnetic sheet 234 are attracted to each other, ensuring the stability of the placement of the tray 232;

[0052] The circuit board to be detected is placed in the stepped groove 2321. The CCD camera 33 and the light source 34 are turned on, and the first servo motor 22 is started to drive the rotating disk 21 to rotate. The rotation of the rotating disk 21 drives the material loading mechanism 23 to rotate, so that different material loading mechanisms 23 correspond to the vision camera module 3. While improving the detection efficiency, it also ensures that the vision camera module 3 is directly opposite to the circuit board to be detected, ensuring the detection accuracy;

[0053] When the circuit board reaches directly below the CCD camera 33, the first servo motor 22 pauses. The CCD camera 33 can clearly collect the appearance image of the circuit board with the help of the light source 34, and transmit the image information to the image processing system for detection;

[0054] After the detection is completed, the first servo motor 22 is restarted to transfer the next circuit board to directly below the CCD camera 33;

[0055] The staff removes the detected circuit board and places the qualified products and unqualified products separately;

[0056] When necessary, the second servo motor 38 is started to drive the threaded column 37 to rotate. Under the action of thread screwing, the lifting plate 31 drives the CCD camera 33 and the light source 34 to lift, adjusting the heights of the CCD camera 33 and the light source 34, and adjusting the distance between the CCD camera 33 and the light source 34 and the circuit board to ensure the detection accuracy.

[0057] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
