[0024] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] An embodiment of the present utility model provides an appearance detection device, such asFigures 1-7 As shown in Figures 1-7 , the appearance detection device includes: a base 1 and a conveying mechanism 2 disposed on the top of the base 1; a fixing frame 3 fixedly installed on the top of the base 1, and the fixing frame 3 covers the conveying mechanism 2; a photoelectric detection device 4 installed in the fixing frame 3, and the photoelectric detection device 4 is located above the conveying mechanism 2; a set of detectors 5 disposed in the fixing frame 3 for detecting the burrs at the water inlet of the lithium battery cover plate. The end diameter of the detection probe of a set of the detectors 5 is the same as the end face diameter of the burrs at the water inlet. A set of the detectors 5 are all located on one side of the photoelectric detection device 4; a sliding mechanism disposed on the fixing frame 3 for driving the set of detectors 5 to slide up and down; a fixing mechanism disposed on the fixing frame 3 for fixing the lithium battery cover plate.

[0026] In this embodiment, during use, first place the lithium battery cover plate on the conveying mechanism 2, and then start the conveying mechanism 2 to convey the material. When the material is conveyed to the detection area of the photoelectric detection device 4, after the photoelectric detection device 4 detects the material, the conveying mechanism 2 automatically shuts down, and at the same time the material stops being conveyed. At this time, the material slides to the lower part of a set of detectors 5. Then start the fixing mechanism to clamp the material, so as to fix it. Then start the sliding mechanism to drive the detectors 5 to slide down, press down the detection probes of the detectors 5, and make the ends thereof contact the end face of the burrs at the water inlet to determine whether the size of the burrs at the water inlet is standard, and complete the detection operation of the material. Through the detectors 5 and the photoelectric detection device 4, accurate identification and determination of the burrs at the water inlet of the lithium battery cover plate are realized, the missed detection rate and over-detection rate are reduced. At the same time, the automated conveying and detection processes reduce manual intervention and improve the detection speed and efficiency.

[0027] In a further preferred embodiment of the present utility model, the sliding mechanism includes: a first threaded barrel 6 rotatably installed on the top inner wall of the fixing frame 3; a first threaded rod 7 threadedly installed on the first threaded barrel 6; two connecting plates 8 disposed below the first threaded rod 7, and a buffer spring 9 is installed between the two connecting plates 8. The connecting plate 8 located above is fixedly connected to the first threaded rod 7; a first motor 10 fixedly installed on the top inner wall of the fixing frame 3; a set of bevel gears 11 respectively fixedly sleeved on the output shaft of the first motor 10 and the first threaded barrel 6, and the set of bevel gears 11 are meshed with each other.

[0028] In this embodiment, when it is necessary to drive the detector 5 to slide down, first start the first motor 10, so that the output shaft of the first motor 10 drives the bevel gear 11 to rotate, and the bevel gear 11 drives the first threaded barrel 6 to rotate synchronously. When the first threaded barrel 6 rotates, it drives the first threaded rod 7 to slide downward, thereby driving the connecting plate 8 to slide down synchronously to perform a driving operation on the detector 5. Through the cooperation of the first threaded barrel 6 and the first threaded rod 7, and the precise control of the first motor 10, the lifting height of the detector 5 is adjusted, improving the accuracy and reliability of detection. At the same time, the setting of the connecting plate 8 and the buffer spring 9 can effectively enhance the stability of the detector 5, reduce the impact and vibration during the lifting process, and protect the detector 5 from damage.

[0029] In a further preferred embodiment of the present utility model, the fixing mechanism includes: a bidirectional screw rod 12 rotatably installed in the fixing frame 3; sliders 13 threadedly sleeved on the bidirectional screw rod 12; a clamping plate 14 fixedly installed at the bottom of the slider 13, and a buffer pad is installed on one side of the clamping plate 14; a driving mechanism provided on one side of the fixing frame 3.

[0030] In this embodiment, before detecting the material, first start the driving mechanism, so that the driving mechanism drives the bidirectional screw rod 12 to rotate, and the bidirectional screw rod 12 drives the slider 13 to slide, and then a group of sliders 13 slide close to each other, so that a group of clamping plates 14 clamp the material to clamp and fix the material. Through the setting of the bidirectional screw rod 12 and the slider 13, it is convenient to clamp and fix the material, thereby ensuring that it will not move during the detection operation.

[0031] In a further preferred embodiment of the present utility model, the driving mechanism includes: a driven gear 15 fixedly sleeved on one end of the bidirectional screw rod 12; an electric telescopic rod 16 fixedly installed on one side of the fixing frame 3; a rack 17 installed on the output rod of the electric telescopic rod 16, and the rack 17 meshes with the driven gear 15.

[0032] In this embodiment, when driving the bidirectional screw rod 12 to rotate, first start the electric telescopic rod 16, so that the output rod of the electric telescopic rod 16 drives the rack 17 to slide, so that the rack 17 drives the driven gear 15 to rotate, and the driven gear 15 drives the bidirectional screw rod 12 to rotate. Through the combination of the electric telescopic rod 16, the rack 17 and the driven gear 15, the precise driving of the bidirectional screw rod 12 is realized, and then the rapid fixing operation of the material is realized.

[0033] In a further preferred embodiment of the present utility model, a U-shaped plate is fixedly installed in the fixing frame 3, and the U-shaped plate covers the bidirectional screw rod 12 and is slidably connected to the slider 13.

[0034] In this embodiment, when the bidirectional screw 12 rotates, the slider 13 is driven to move along its axial direction through the threaded connection. At this time, the U-shaped plate acts as a guide to limit the lateral movement of the slider 13, ensuring that the slider 13 can only slide in a straight line along the inner wall of the U-shaped plate. This arrangement not only improves the smoothness of the movement of the slider 13, but also reduces the friction and wear caused by lateral deviation, thereby extending the service life of the equipment. The U-shaped plate provides stable support and guidance for the bidirectional screw 12 and the slider 13, thereby enhancing the stability of the entire sliding mechanism and reducing position deviations caused by vibration or impact.

[0035] In a further preferred embodiment of the utility model, a group of fixing plates 18 are fixedly installed on one side of the inner wall of the fixing frame 3, a group of the fixing plates 18 are rotatably installed with a second threaded cylinder 19, a group of the second threaded cylinders 19 are threadedly installed with a second threaded rod 20, a group of the bottom ends of the second threaded rods 20 are respectively installed with limiting plates 21, a group of the top ends of the second threaded cylinders 19 are installed with a sprocket 22, a group of the sprockets 22 are sleeved with a chain 23, the chain 23 is meshed with the sprocket 22, a second motor 24 is installed on one side of the inner wall of the fixing frame 3, and the output shaft of the second motor 24 is fixedly connected to any output rod of the sprocket 22.

[0036] In this embodiment, after the material slides into the fixed frame 3, the second motor 24 is started so that the output shaft of the second motor 24 drives the sprocket 22 to rotate, and the sprocket 22 drives the chain 23 to rotate, so that a group of sprockets 22 rotate synchronously, so that a group of sprockets 22 synchronously drives a group of second threaded cylinders 19 to rotate, so that the second threaded cylinder 19 drives the second threaded rod 20 to slide, and the second threaded rod 20 drives the limit plate 21 to slide down, so that the limit plate 21 slides down and approaches the conveying mechanism 2. When the material is conveyed to the bottom of the photoelectric detection device 4, the material contacts the limit plate 21 at the same time, so that the limit plate 21 limits a group of materials conveyed simultaneously, thereby facilitating the subsequent detection operation of the material by the detector 5. Through the combined design of the sprocket 22, the chain 23 and the second motor 24, the synchronous lifting and lowering of multiple second threaded rods 20 is realized, ensuring the smooth adjustment of a group of limit plates 21 in the vertical direction.

[0037] In a further preferred embodiment of the utility model, guide rods 25 are fixedly installed on the fixed frame 3 and the fixed plate 18, and an L-shaped plate 26 is slidably installed on a group of the guide rods 25, and a group of the L-shaped plates 26 are fixedly connected to the connecting plate 8 and the limiting plate 21 respectively.

[0038] In this embodiment, the provision of the guide rod 25 and the L-shaped plate 26 provides stable guidance and support for the movement of the connecting plate 8 and the limiting plate 21, thereby reducing errors and wear caused by offset or shaking.

[0039] In summary, compared with the related art, the device accurately identifies and determines whether the flash on the water inlet of the lithium battery cover plate exceeds the standard through the detector, effectively solving the problems of possible missed inspection or over-inspection in manual visual inspection.
