[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 7 As shown, this utility model provides a product appearance visual inspection device, including an inspection table 1 and an inspection head 2. The inspection head 2 is located above the inspection table 1 and is fixedly connected to the inspection table 1 by a bracket. A cavity is opened at the bottom of the inspection head 2, a protective component 3 is arranged inside the cavity, an inspection instrument 4 is installed at the top of the cavity, and a cleaning component 5 is arranged at the bottom of the cavity.
[0029] The cleaning component 5 includes a disassembly ring 53 threaded onto the bottom of the detection head 2. An airbag ring 54 is fixedly connected to the inner side of the disassembly ring 53, and a polishing cotton 55 is fixedly connected to the inner side of the airbag ring 54. The airbag ring 54 has an inverted "L" shaped cross-section, and its top abuts against the detection head 2. Due to the design of the cleaning component 5, the surface of the protective component 3 can be polished when it is raised or lowered to achieve a bright and transparent state, facilitating observation during the detection process. With the airbag ring 54, the inner surface of the polishing cotton 55 can be controlled to contact the outer surface of the visual protective cover 31 through the disassembly ring 53 in cooperation with the detection head 2, thereby achieving a controllable polishing effect. Moreover, rotating the disassembly ring 53 in the reverse direction makes it easy to remove it, the airbag ring 54, and the polishing cotton 55 as a whole, facilitating the replacement of the cleaning agent.
[0030] The cavity is also fitted with a feed pipe 51 located above the airbag ring 54. The inner side of the feed pipe 51 is fixedly connected with several evenly distributed discharge nozzles 52, and the discharge nozzles 52 are all connected to the feed pipe 51. Due to the setting of the discharge nozzles 52, the feed pump can spray polishing agent onto the surface of the visual protective cover 31 through the feed pipe 51 and the discharge nozzles 52, so that the visual protective cover 31 can be polished with the help of the polishing cotton 55 when it spirals up and down.
[0031] The detection head 2 is equipped with a controller, an air pump and a material pump located above the cavity. One end of the air pump is connected to the outside air, and the other end of the air pump is connected to a T-junction.
[0032] The top of the detector 4 is connected to a pneumatic rod, the top of which is connected to the top of the cavity. The upper end of the pneumatic rod is connected to the air pump tee through a pipe with a solenoid valve. The top of the conveying pipe 51 is connected to the conveying pump through a pipe.
[0033] The protective component 3 includes a visual protective cover 31 that is movably fitted inside the cavity polishing cotton 55 and several discharge nozzles 52. The outer surface of the upper end of the visual protective cover 31 is movably fitted inside the cavity, and the outer surface of the lower end of the visual protective cover 31 is movably fitted inside the polishing cotton 55.
[0034] Among them, a number of limiting telescopic rods 32 are evenly distributed around the detector 4 above the visual protective cover 31. The top of the limiting telescopic rod 32 is connected to a connecting ring 33. The top of the connecting ring 33 is connected to the air pump tee through a pipe with a solenoid valve. The bottom of the movable end of the limiting telescopic rod 32 is connected to a linkage component 34.
[0035] The linkage component 34 includes a linkage sleeve 341 that is movably fitted between the cavity and the detector 4. The linkage sleeve 341 is fixedly connected to the top of the visual protective cover 31. A linkage ring 342 is movably fitted inside the linkage sleeve 341. The top of the linkage ring 342 extends to the top of the linkage sleeve 341 and is fixedly connected to the bottom of several limiting telescopic rods 32. Due to the setting of the linkage component 34, the cooperation of the linkage sleeve 341 and the linkage ring 342 can ensure the connection between the lower end of the limiting telescopic rod 32 and the visual protective cover 31, so that the visual protective cover 31 can be driven to descend or rise when the limiting telescopic rod 32 extends or retracts. Moreover, the cooperation of the linkage component 34 and the guide slide 35 ensures that the visual protective cover 31 is not restricted by the limiting telescopic rod 32 when it rotates.
[0036] The cavity has several evenly distributed guide grooves 35 on its inner wall. Several evenly distributed guide balls 36 are movably installed inside the guide grooves 35. The guide balls 36 are movably embedded in the outer side of the upper end of the visual protective cover 31. Due to the setting of the guide grooves 35, with the cooperation of the guide balls 36, when the limiting telescopic rod 32 drives the visual protective cover 31 to move up and down along the inside of the detection head 2, the visual protective cover 31 can be rotated, thereby allowing the polishing agent sprayed by the nozzle 52 onto its surface to be spread evenly, ensuring that the polishing cotton 55 and the visual protective cover 31 can be fully filled with polishing agent, thus ensuring the polishing effect.
[0037] Working principle and usage process of this utility model:
[0038] After placing the product to be tested directly below the testing head 2 on the testing platform 1, turn on the equipment so that the air pump injects air into the interior of several limiting telescopic rods 32 through the connecting ring 33, causing the several limiting telescopic rods 32 to extend synchronously. This allows the lower end of the limiting telescopic rods 32 to push the visual protective cover 31 to move slowly downward through the linkage component 34. During the downward movement of the visual protective cover 31, the cooperation of the guide slide 35 and the guide ball 36 causes the visual protective cover 31 to slowly spiral down along the inner wall of the testing head 2, so as to cover the product to be tested placed on the testing platform 1 with the cooperation of the testing platform 1.
[0039] The air pump extracts the air from the connecting ring 33, which shortens the limiting telescopic rod 32. Then, with the cooperation of the guide groove 35 and the guide ball 36, the visual protective cover 31 slowly spirals upward in the opposite direction so as to retract the visual protective cover 31.
[0040] When the visual protective cover 31 needs to be polished and cleaned, rotate the bottom of the disassembly ring 53 so that it rises with the cooperation of the detection head 2 and squeezes the airbag ring 54. This causes the inner ring of the airbag ring 54 to expand inward, thereby reducing its inner diameter until the inner surface of the polishing cotton 55 inside the airbag ring 54 is in contact with the surface of the visual protective cover 31. At the same time, the feed pump sprays polishing agent onto the surface of the visual protective cover 31 through the feed pipe 51 and the discharge nozzle 52. Later, as the visual protective cover 31 spirals up and down, the surface of the visual protective cover 31 can be polished and ground with the polishing cotton 55.
[0041] Rotating the disassembly ring 53 in the reverse direction will release the pressure on the upper end of the airbag ring 54, thereby expanding its inner diameter and moving the polishing cotton 55 away from the visual protective cover 31; continuing to rotate the disassembly ring 53 in the reverse direction will allow it to be removed as a whole along with the airbag ring 54 and the polishing cotton 55 for cleaning or replacement.
