[0026] In this embodiment, the first pressing wheel 208 is disposed on the fixing rod 207 between the paging unit 1 and the detection unit 2 , so as to facilitate the smooth transition of the silk-screen label from the paging unit 1 to the detection unit 2 .

[0027] In this embodiment, the slide rail adjustment knob 218 is disposed on the slide rail adjustment seat 217 and can be used to adjust and lock the positions of the industrial camera 221 and the light source 222 to facilitate debugging of the detection device.

[0028] In this embodiment, the light source fixing plate 223 is connected and fixed to the light source distance adjustment plate 224, and a waist hole is provided on the light source fixing plate 223 to facilitate adjustment of the horizontal spacing position of the light source 222. The light source fixing plate 223 is set to a 45-degree bending angle to avoid the incident direction of the light source 222 causing reflections on the silk-screen label product and affecting the shooting effect of the industrial camera 221.

[0029] In this embodiment, the detection box baffle 209 is fixed to the four sides and the top of the detection box frame 210 to avoid interference from ambient light when the device is working, thereby preventing the visual shooting effect from being affected.

[0030] In this embodiment, the sensor 220 and the industrial camera 221 are fixed in parallel on the camera fixing plate 219. When the sensor 220 detects the labeled product on the conveyor belt 211 at the detection position below, it promptly provides a signal to the industrial camera 221 to facilitate timely shooting, transmission, analysis and provision of detection results.

[0031] In this embodiment, the transition plate 301 is connected to the lifting cylinder 304 through a short rod 302. The movement of the lifting cylinder 304 will directly act on the transition plate 301. When the label is qualified, it will not move. When it is unqualified, the transition plate 301 will be lifted.

[0032] In this embodiment, the transition plate 301 is designed to be in the shape of an inverted triangle. When the label is inspected to be qualified, the upper plane provides a smooth transition effect. When the label is inspected to be defective, the side slope will guide the defective label through the waste inclined plate 303 at the bottom into the waste box 306.

[0033] In this embodiment, the second pressure wheel 411 and the third pressure wheel 413 are fixed on the rectangular rod 412, and the second pressure wheel 411 is arranged at the front position of the transition plate 301.

After the transition plate 301 is lifted, it is conducive to the smooth sliding of the silk-screen label into the waste box 306. The third pressure wheel 413 is arranged at the end position of the unloading unit 4, which is conducive to the smooth delivery of the silk-screen label to the unloading plate 403.

[0034] In this embodiment, the expansion flat plate 402 is connected to the blanking plate 403, and the waist holes arranged on both sides of the expansion platform 402 can flexibly adjust the blanking storage space according to the size of the silk-screen label.

[0035] In this embodiment, the motor adjustment module 205 and the light source adjustment module 204 are fixed in the control box 203, and the control box 203 is set in the middle position of the frame 5, which is convenient for adjusting the speed of the conveyor belts in the paging unit 1, the detection unit 2 and the unloading unit 4, and the light source adjustment module 204 is convenient for adjusting the brightness of the light source 222.

[0036] The working process and principle of the device: Before the detection device is used, the positions of the light source 222 and the industrial camera 221 are adjusted according to the labels to be detected, and the paging unit 1, the detection unit drive motor 227, and the unloading unit drive motor 405 are started to put the stacked silk-screen label products into the paging unit 1. At this time, under the action of the paging unit 1 and the first pressure wheel 208, the silk-screen labels are output one by one to the detection position conveyor belt 211. When passing through the detection unit 2, the sensor 220 detects the silk-screen label below and gives a feedback signal to the industrial camera 221. The industrial camera 221 receives the signal to trigger the photo action, and the taken photos are transmitted to the industrial computer 202 After analysis and processing, the pictures and results are transmitted to the display screen 201 for the operating staff to view. If the test result is good, the silk-screen label is transported to the unloading unit 4 through the upper surface of the transition plate 301 under the action of the second pressure wheel 411, and the qualified label products are finally stacked on the unloading plate 403. If the test result is unqualified, the transition plate 301 is lifted by the lifting cylinder 304, and the silk-screen label product can be pushed directly to the inclined waste inclined plate 303 at the bottom under the action of the second pressure wheel 411. At this time, the transition plate 301 falls, and the silk-screen label finally slides into the waste bin 306, and the automatic detection process of a single silk-screen label is completed.
