[0022] The detection assembly 2 includes a ring 201, an external gear ring 202 is rotatably installed on the inner ring surface of the ring 201, and a CCD camera 203 is fixedly installed on the inner ring surface of the external gear ring 202;

[0023] The feeding assembly 3 includes a linear motor 301, two sliders are threadedly sleeved on the threaded rod of the linear motor 301, vertical plates 302 are fixedly installed on the top surfaces of the two sliders, a feeding frame plate 303 is fixedly installed at the top edge of the opposite surfaces of the two vertical plates 302, square grooves are formed on the top surfaces of the two feeding frame plates 303, and support pads 304 are fixedly installed at the four corners of the square grooves.

[0024] In this embodiment, the driving gear 105 is located above the ring 201, an opening is formed at the top of the outer ring surface of the ring 201, the bottom of the driving gear 105 is located in the opening, and the bottom of the driving gear 105 is meshed with the external tooth surface of the external gear ring 202. The rotation of the driving gear 105 can drive the external gear ring 202 to rotate in the ring 201, and the rotation of the external gear ring 202 can drive the CCD camera 203 to rotate, so as to detect the stainless steel plate 305 of the mobile phone back plate from different angles.

[0025] A mobile phone back plate stainless steel plate 305 is placed between the four support pads 304. The feeding frame plate 303 and the support pads 304 are both made of transparent glass materials, which can facilitate the CCD camera 203 to detect the surface of the mobile phone back plate stainless steel plate 305.

[0026] On both sides of the outer ring surface of the ring 201, connection blocks 204 are fixedly installed, and the inner sides of the two vertical parts of the C-shaped frame 102 are respectively fixedly connected to one end of the two connection blocks 204.

[0027] The linear motor 301 is fixedly installed on the top surface of the bottom plate 101. When the linear motor 301 is started, the linear motor 301 rotates to drive the two sliders to move. By moving the two sliders, the two vertical plates 302 can be driven to move. When the vertical plates 302 move, the loading frame plate 303 can be driven to move. By moving the loading frame plate 303, the stainless steel plate 305 of the mobile phone backplane placed in the loading frame plate 303 can be driven to move, so that the stainless steel plate 305 of the mobile phone backplane can be controlled to move into the detection component 2.

[0028] During use, the stainless steel plate 305 of the mobile phone backplane to be detected is taken out and then placed flat between the four support pads 304.

When the driving gear 105 rotates, the outer gear ring 202 can be driven to rotate within the ring 201. By rotating the outer gear ring 202, the CCD camera 203 can be driven to rotate, and thus the stainless steel plate 305 of the mobile phone backplane can be detected from different angles, and the outer surface of the stainless steel plate 305 of the mobile phone backplane can be conveniently detected in all directions. While the stainless steel plate 305 of the mobile phone backplane located at the detection position is being detected, another loading frame plate 303 will move out of the detection component 2. Therefore, while the stainless steel plate 305 of the mobile phone backplane located at the detection position is being detected, the staff can synchronously perform unloading and loading operations on the stainless steel plate 305 of the mobile phone backplane placed on the top surface of the other loading frame plate 303 outside, reducing the idle time of the detection device and improving the detection efficiency.

[0029] In summary, the surface defect detection device can facilitate the loading and unloading of the stainless steel plate 305 of the mobile phone backplane. The steps are simple. At the same time, the rotation of the driving gear 105 can drive the external gear ring 202 to rotate within the ring 201. The rotation of the external gear ring 202 can drive the CCD camera 203 to rotate, so as to detect the stainless steel plate 305 of the mobile phone backplane from different angles, and can conveniently perform a full-range detection on the outer surface of the stainless steel plate 305 of the mobile phone backplane. While detecting the stainless steel plate 305 of the mobile phone backplane located at the detection position, another loading frame plate 303 will move out of the detection assembly 2. Therefore, while detecting the stainless steel plate 305 of the mobile phone backplane located at the detection position, the staff can synchronously perform the unloading and loading operations on the stainless steel plate 305 placed on the top surface of another loading frame plate 303 outside, reducing the idle time of the detection device and improving the detection efficiency.
