[0039] Reference Figure 1-Figure 7, wherein the detection component 400 includes a limit slide box 401, the limit slide box 401 is fixedly connected to the side wall of the mounting frame 300, the inner wall of the limit slide box 401 is slidably connected to a detection slide bar 402, and the detection slide bar 402 is fixedly connected to a side close to the conveyor belt 102 with a visual detection probe 403, the visual detection probe 403 adopts the existing mature technology, the specific model is acA1920-150um, and is electrically connected to an external computer terminal, so as to compare the detection result image data with the qualified product data, In order to complete the visual inspection of the outside of the material, the side wall of the mounting frame 300 is rotatably connected to a driven shaft 404, and the side wall of the driven shaft 404 is fixedly connected to a toggle rod 405, and the toggle rod 405 is movably fitted with the side wall of the detection slide bar 402, and the driven shaft 404 is connected to the transmission roller 101 through a pulley group 4041. The axis of the driven shaft 404 deviates from the central axis of the limit slide box 401, and the toggle rod 405 sweeps and pushes the detection slide bar 402 to a distance that is less than the distance that the detection slide bar 402 slides in the limit slide box 401. The maximum length of the transmission belt 102 is fixedly connected to the side wall of the transmission belt 102, and a driving rod 4061 is fixedly connected to the bottom of the positioning plate 200. The driving rod 4061 penetrates into the driving box 406 and is fixedly connected to the driving blade 4062. The side wall of the driving box 406 is fixedly connected to a connecting seat 4063, and an oblique spray groove 4064 is provided in the connecting seat 4063. The side wall of the visual detection probe 403 is fixedly connected to a synchronization rod 407, and the end of the synchronization rod 407 away from the visual detection probe 403 is in contact with the connecting seat 4063. The mounting frame 300 is connected to the side wall of the mounting frame 300, and an airflow box 408 is fixedly connected to the side wall of the airflow box 408. An airflow blade 4081 is rotatably connected inside the airflow box 408. The rotating shaft of the airflow blade 4081 is fixedly connected to the end of the driven rotating shaft 404. An airflow hose 4082 is fixedly connected to the side wall of the airflow box 408. One end of the airflow hose 4082 away from the airflow box 408 is connected to the inner cavity of the synchronization rod 407. Anti-blocking grooves 1011 are provided in the middle of the transmission rollers 101 on both sides. The internal dimensions of the anti-blocking grooves 1011 are larger than the external dimensions of the driving box 406.

[0040] By the arrangement of the above structure, the servo motor 103 is turned on, and the transmission roller 101 will drive the driven shaft 404 to rotate through the pulley group 4041, so that the toggle rod 405 is swept along the driven shaft 404, and thereby the detection slide bar 402 is pushed to slide in the limit slide box 401, thereby bringing the visual detection probe 403 to move synchronously. At the same time, during the rotation of the driven shaft 404, the airflow blade 4081 in the airflow box 408 will also be driven to rotate, so as to generate airflow thrust in the airflow box 408, and the thrust is transmitted to the airflow hose 4082 through the airflow hose 4082. The synchronous rod 407 is inside the synchronous rod 407, and at this time the synchronous rod 407 is just connected to the oblique spray slot 4064, so the airflow thrust will enter the drive box 406 along the oblique spray slot 4064, and impact the drive blade 4062, thereby pushing the drive blade 4062 to rotate, so that the drive rod 4061 drives the positioning plate 200 to rotate, so that during the material movement process, the material rotates, and at this time the visual inspection probe 403 moves synchronously with the material, thereby realizing a comprehensive inspection of the material all around, effectively improving the inspection effect, and ensuring the qualified rate of the material.

[0041] Reference Figure 3 , Figure 5 , wherein a reset cylinder 409 is fixedly connected to the side wall of the mounting frame 300, an extrusion plate 4091 is slidably connected to the inner wall of the reset cylinder 409, the extrusion plate 4091 is fixedly connected to the side wall of the detection slide bar 402, a second spring 4092 is fixedly connected to the inner wall of the reset cylinder 409, an auxiliary flushing groove 4093 is provided on the side wall of the reset cylinder 409, an auxiliary flushing piston 4094 is slidably connected in the auxiliary flushing groove 4093, a third spring 4095 is fixedly connected between the auxiliary flushing piston 4094 and the auxiliary flushing groove 4093, an auxiliary flushing pipe 4096 is connected to the side wall of the auxiliary flushing groove 4093, and one end of the auxiliary flushing pipe 4096 away from the auxiliary flushing groove 4093 is connected to the inner cavity of the airflow hose 4082;

[0042] Through the arrangement of the above-mentioned structure, when the detection slide bar 402 slides in the limit slide box 401, its side wall will squeeze the auxiliary piston 4094, causing the auxiliary piston 4094 to retract into the auxiliary groove 4093, thereby compressing the airflow in the auxiliary groove 4093 and allowing the airflow to enter the airflow hose 4082 along the auxiliary pipe 4096, thereby increasing the impulse of the airflow entering the drive box 406, thereby ensuring the rotation effect of the positioning plate 200 and improving the detection efficiency; then when the material moves out of the work station below the mounting frame 300, the toggle rod 405 will rotate out of the area that fits with the detection slide bar 402. At this time, under the rebound action of the second spring 4092, the detection slide bar 402 will be pushed back and reset, and this reciprocating motion does not require manual auxiliary detection, effectively improving the detection efficiency.

[0043] Reference Figure 7, Figure 8 , wherein a fixed plate 600 is fixedly connected to the inner wall of the telescopic sleeve 201, the fixed plate 600 is slidably connected to the side wall of the telescopic sleeve rod 202, a sliding plate 601 is fixedly connected to the side wall of the telescopic sleeve rod 202, the side wall of the sliding plate 601 is slidably connected to the inner wall of the telescopic sleeve 201, an air guide pipe 602 is connected to the side wall of the telescopic sleeve 201, an air guide groove 603 is opened in the inner cavity of the driving rod 4061, the air guide groove 603 is connected to the inner cavity of the driving box 406, and one end of the air guide pipe 602 away from the telescopic sleeve 201 is connected to the air guide groove 603;

[0044] Through the arrangement of the above structure, after the airflow continuously rushes into the driving box 406 to drive the driving blade 4062 to rotate, a part of the airflow will enter the telescopic sleeve 201 along the air guide groove 603 and the air guide tube 602, thereby increasing the air pressure in the telescopic sleeve 201, thereby pushing the sliding plate 601 to move toward the side of the compressed first spring 203, thereby pulling the telescopic sleeve rod 202 to retract, so that the clamping plate 204 fits more closely with the side wall of the material, thereby improving the stability of the material during the rotation detection process.

[0045] Reference Figure 3-Figure 5 , wherein the buffer mechanism 500 comprises a buffer main cylinder 501, the buffer main cylinder 501 is fixedly connected to the side wall of the limit slide box 401, a buffer main rod 502 is slidably connected to the inner wall of the buffer main cylinder 501, the buffer main rod 502 penetrates into the limit slide box 401 and is sleeved with a fourth spring 503, a cleaning nozzle 504 is connected to the side wall of the buffer main cylinder 501, a buffer auxiliary groove 505 is provided on the side wall of the detection slide bar 402, a buffer auxiliary rod 506 is slidably connected to the inner wall of the buffer auxiliary groove 505, a fifth spring 507 is fixedly connected between the buffer auxiliary rod 506 and the buffer auxiliary groove 505, a dustproof tube 508 is connected to the side wall of the visual detection probe 403, and one end of the dustproof tube 508 away from the visual detection probe 403 is connected to the inner cavity of the buffer auxiliary groove 505, wherein the side of the buffer main rod 502 in contact with the buffer auxiliary rod 506 is made of wear-resistant silicone material;

[0046] By setting the above structure, when the second spring 4092 pushes the detection slide rod 402 to move back and reset, under the action of the final thrust inertia, the detection slide rod 402 will rush toward the buffer main rod 502, and the buffer main rod 502 will collide with the buffer auxiliary rod 506. At this time, the buffer main rod 502 will retract into the buffer main cylinder 501, and will squeeze the airflow in the buffer main cylinder 501, so that the airflow is sprayed outward along the cleaning nozzle 504, so as to blow and clean the surface of the material under the cleaning nozzle 504, ensuring that the surface of the material is not covered with dust and impurities that affect visual detection, thereby improving visual inspection. The accuracy of measurement will be improved; and the buffer auxiliary rod 506 will also retract into the buffer auxiliary groove 505, which will squeeze the airflow in the buffer auxiliary groove 505, so that the airflow will blow along the dustproof tube 508 to the inner wall of the end of the visual detection probe 403, thereby cleaning the dust and impurities on the inner wall of the end of the visual detection probe 403, effectively improving the detection effect of the visual detection probe 403, and ensuring the accuracy of the final detection result; and under the buffering effect of the fourth spring 503 and the fifth spring 507, the impact force received by the visual detection probe 403 during rebound reset is effectively reduced, thereby improving the protection effect of the visual detection probe 403.

[0047] Specifically, when the material visual inspection device is working / in use, the following steps are specifically included:

[0048] The material to be inspected is placed on the positioning plate 200 from one side of the transmission frame 100. During the process of placing the material, the side wall of the material will squeeze the clamping plate 204, so that the telescopic sleeve 202 is pulled outward. Then, under the rebound effect of the first spring 203, the material is stably clamped between the three clamping plates 204. Then, the servo motor 103 is operated to drive the positioning plate 200 to the next station. After each station, the servo motor 103 will pause to facilitate material placement and material collection, thereby improving the convenience of the inspection operation.

[0049] When the material enters the station below the mounting frame 300, the synchronization rod 407 will fit exactly with the connecting seat 4063 and be connected with the inclined spray slot 4064. At this time, the servo motor 103 will start again, and the transmission roller 101 will drive the driven shaft 404 to rotate through the pulley group 4041, so that the toggle rod 405 can sweep along the driven shaft 404. When the toggle rod 405 rotates to the upper side, it will fit with the side wall of the detection slide bar 402, and thereby push the detection slide bar 402 to slide in the limit slide box 401, thereby carrying out visual detection. The probe 403 moves synchronously. At the same time, during the rotation of the driven shaft 404, the airflow blade 4081 in the airflow box 408 will also be driven to rotate, thereby generating airflow thrust in the airflow box 408, and transmitting the thrust to the synchronization rod 407 through the airflow hose 4082. At this time, the synchronization rod 407 is connected to the oblique nozzle slot 4064. Therefore, the airflow thrust will enter the drive box 406 along the oblique nozzle slot 4064 and impact the drive blade 4062, thereby pushing the drive blade 4062 to rotate. The driving rod 4061 drives the positioning plate 200 to rotate, so that the material rotates during the movement of the material, and the visual detection probe 403 moves synchronously with the material at this time, so as to achieve a comprehensive detection of the material around, effectively improve the detection effect, and ensure the qualified rate of the material; and in the process of the detection slide bar 402 sliding in the limit slide box 401, its side wall will also squeeze the auxiliary piston 4094, so that the auxiliary piston 4094 retracts into the auxiliary groove 4093, thereby compressing the auxiliary groove 4094. 093, and make the airflow enter the airflow hose 4082 along the auxiliary flushing pipe 4096, thereby increasing the airflow impulse entering the driving box 406, thereby ensuring the rotation effect of the positioning plate 200 and improving the detection efficiency; then when the material moves out of the station below the mounting frame 300, the toggle rod 405 will rotate out of the area that fits the detection slide bar 402. At this time, under the rebound effect of the second spring 4092, the detection slide bar 402 will be pushed back to reset, and this reciprocating movement does not require manual auxiliary detection, which effectively improves the detection efficiency;

[0050] After the airflow continuously rushes into the driving box 406 to drive the driving blade 4062 to rotate, a part of the airflow will enter the telescopic sleeve 201 along the air guide groove 603 and the air guide tube 602, thereby increasing the air pressure in the telescopic sleeve 201, thereby pushing the sliding plate 601 to move toward the side of the compressed first spring 203, thereby pulling the telescopic sleeve rod 202 to retract, so that the clamping plate 204 fits more closely with the side wall of the material, thereby improving the stability of the material during the rotation detection process;

[0051] When the second spring 4092 pushes the detection slide rod 402 to move back and reset, under the action of the final thrust inertia, the detection slide rod 402 will rush toward the buffer main rod 502. At this time, the buffer main rod 502 will collide with the buffer auxiliary rod 506. Under this collision force, the buffer main rod 502 and the buffer auxiliary rod 506 will retract into the buffer main tube 501 and the buffer auxiliary groove 505 respectively. When the buffer main rod 502 retracts into the buffer main tube 501, it will squeeze the airflow in the buffer main tube 501, so that the airflow will be sprayed outward along the cleaning nozzle 504, thereby The material surface below the cleaning nozzle 504 is cleaned by blowing air to ensure that the material surface is not covered by dust and impurities that affect visual detection, thereby improving the accuracy of visual detection. When the buffer auxiliary rod 506 retracts into the buffer auxiliary groove 505, the airflow in the buffer auxiliary groove 505 will be squeezed, so that the airflow blows along the dustproof tube 508 toward the inner wall of the end of the visual detection probe 403, thereby cleaning the dust and impurities on the inner wall of the end of the visual detection probe 403, effectively improving the detection effect of the visual detection probe 403 and ensuring the accuracy of the final detection result.
