Description

Technical Field

[0001] The utility model belongs to the technical field of bearing preparation, and in particular relates to oil pollution cleaning equipment for video detection. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are key components for the rotation of various electromechanical equipment. The quality of their technical parameters has a direct impact on the continuous, stable and safe operation of electromechanical equipment.

[0003] Bearings are generally composed of inner rings, outer rings, rolling elements and cages. Cages are bearing parts that partially wrap all or part of the balls and move with them. They are used to isolate the balls and usually guide the balls and keep them in the bearings. In mechanized bearing production lines, workpieces (cages, etc.) need to be quality inspected, and video inspection of workpieces is undoubtedly an efficient and fast inspection method.

[0004] The detection platform of existing video detection equipment is usually made of smooth translucent materials such as glass, and a lighting device is provided at the bottom of the detection platform. When inspecting a workpiece, it is necessary to move the workpiece to the detection platform and shoot the workpiece through a camera located above the workpiece to perform shadow imaging inspection on the workpiece. However, during the production process of the workpiece, the workpiece will be contaminated with lubricating oil on the equipment. After a long period of work, the translucent surface of the detection platform will have oil marks and become non-translucent, affecting the video detection effect. Utility Model Content

The to-be-inspected area 21 is provided with a first push rod mechanism 23 and a sensor 24 for controlling the first push rod mechanism 23. The first push rod mechanism 23 can push the workpiece from the to-be-inspected area 21 to the detection area 22. The detection area 22 is provided with a light-transmitting plate 25 and a camera 26. The camera 26 is mounted directly above the light-transmitting plate 25 through a support frame 27 to perform shadow imaging detection on the workpiece. The cleaning mechanism 3 is installed to the detection area 22, and the cleaning mechanism 3 includes an elastic T-shaped bracket, a second push rod mechanism 32, an oil-wiping rod 33 and an assisting tension spring 34. The second push rod mechanism 32 is installed to the elastic T-shaped bracket, the oil-wiping rod 33 is installed to the head end of the second push rod mechanism 32 and abuts against the light-transmitting plate 25, and the assisting tension spring 34 connects the end of the second push rod mechanism 32 and the top of the support frame 27. The assisting tension spring 34 has an inclined upward pulling force on the second push rod mechanism 32, so that the oil-wiping rod 33 abuts against the light-transmitting plate 25, thereby cleaning the stains on the surface of the light-transmitting plate 25.

[0032] In one embodiment, the workpiece to be tested is moved to the inspection area 21 of the workpiece bottom plate 2 through the conveying mechanism. Specifically, the motor 12 drives the workpiece on the conveyor belt 11 to move to the inspection area 21 of the workpiece bottom plate 2. The workpiece hits the sensor to trigger the first push rod mechanism 23, and the first push rod mechanism 23 performs a reciprocating motion to push the workpiece from the inspection area 21 to the inspection area 22. The camera 26 performs imaging detection on the workpiece above the light-transmitting plate 25 in the inspection area 22 to realize the detection of the workpiece. It should be noted that the imaging detection of the workpiece by the camera 26 belongs to the prior art, and the specific imaging detection principle of the camera 26 is not within the protection scope of this application, and the camera detection principle is no longer summarized.

[0033] In one embodiment, the second push rod mechanism 32 can reciprocate once within a set time interval, that is, the second push rod mechanism 32 pushes the oil-wiping rod 33 to reciprocate once along the light-transmitting plate 25 to wipe the stains on the light-transmitting plate 25. It should be noted that the timer in the second push rod mechanism 32 belongs to an existing timer switch and will not be described in detail.

[0034] In one embodiment, when the oil-wiping rod 33 wipes the oil stains on the light-transmitting plate 25, there is often a gap between the oil-wiping rod 33 and the light-transmitting plate 25, that is, the area of ​​the light-transmitting plate 25 wiped by the oil-wiping rod 33 is incomplete. Therefore, a booster spring 34 is provided at the tail of the second push rod mechanism 32, and the booster spring 34 applies a pulling force to the tail of the second push rod mechanism 32 in an inclined upward direction. Since the body of the second push rod mechanism 32 is mounted on the elastic T-shaped bracket, the oil-wiping rod 33 at the front end of the second push rod mechanism 32 has a certain squeezing force on the light-transmitting plate 25, thereby enabling the oil-wiping rod 33 to squeeze and wipe the light-transmitting plate 25 to improve the cleaning effect.

[0043] Preferably, a sensing pressure plate 241 is provided on the side of the sensor 24 facing the conveying device 1 to increase the triggering area of ​​the sensor 24 .

[0044] In one embodiment, when the conveying mechanism conveys the workpiece to the test area, the workpiece touches the sensing plate 241 and is blocked by the sensing plate 241, and the sensing plate 241 transmits a signal to the sensor 24, and the sensor 24 again transmits the data signal to the first push rod mechanism 23, and the first push rod mechanism 23 is started to realize the pushing of the workpiece.

[0045] Preferably, a supporting frame 4 is installed at the bottom of the conveying device 1 and the bottom plate 2 , and the supporting frame 4 has a variety of supporting heights to adjust the heights of the conveying device 1 and the bottom plate 2 .
