[0002] Bearings are an important component in modern mechanical equipment, used to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] Before leaving the factory, bearings undergo visual inspection. This inspection is crucial because surface quality significantly impacts bearing performance. Surface roughness and smoothness affect operating efficiency and lifespan. Defects such as cracks, inclusions, bubbles, and burrs can cause fatigue spalling during high-speed operation, ultimately leading to bearing failure. Therefore, visual inspection is a vital component of bearing quality control. Rigorous visual inspection ensures that bearing surface quality meets standards, reducing bearing failures caused by surface defects and thus guaranteeing the safe operation and extended service life of machinery.

[0004] Currently, the visual inspection of bearings is usually carried out manually by inspecting each bearing one by one. This manual inspection method has low inspection efficiency, and the eyes are prone to fatigue after working for a long time, which may lead to misjudgment of the bearing's appearance. Therefore, it needs to be improved. Utility Model Content

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0022] Please refer to the following: Figures 1 to 3 As shown, Figure 1 A schematic diagram of the overall structure of the bearing visual inspection device 100; Figure 2 This is a structural schematic diagram of the lead screw module 30 and the material tray 40; Figure 3 for Figure 2 Enlarged structural diagram at point A in the middle.

[0023] This utility model provides the following technical solution: a bearing appearance inspection device 100, including a base 10, three sets of vision inspection components 20, a lead screw module 30, and a detection computer 50; the three sets of vision inspection components 20 are arranged sequentially at the top of the base 10; the lead screw module 30 is disposed on the base 10 and is located at the bottom of the three sets of vision inspection components 20, and three material trays 40 are sequentially connected to the lead screw module 30; the detection computer 50 is disposed on the side of the base 10, and the detection computer 50 is electrically connected to the three sets of vision inspection components 20 respectively.

[0024] In the bearing appearance inspection device 100 provided in this embodiment, when performing visual inspection of the bearings, the lead screw module 30 drives three trays 40 to move to the side of the base 10 near the user. The user then places three bearings into the three trays 40 respectively. Next, the lead screw module 30 drives the three trays 40, each loaded with bearings, to move to the bottom of the three sets of visual inspection components 20. Then, the three sets of visual inspection components 20 simultaneously capture images of the bearings loaded in the three trays 40. Finally, the three sets of visual inspection components 20 transmit their respective captured images to... On the inspection computer 50, the bearing images captured by each visual inspection component 20 are compared with pre-stored standard bearing images to determine whether each bearing has any appearance defects. After inspection, the lead screw module 30 moves three trays 40, each loaded with bearings, to the side of the base 10. The user can then manually remove the inspected bearings from the three trays 40. Based on the inspection feedback from the inspection computer 50, the user can categorize and place the defective and qualified bearings. This process is repeated to sequentially inspect each bearing. In this invention, by setting three sets of visual inspection components 20 on the base 10 and connecting the three trays 40 with the lead screw module 30, the transmission components can move the bearings loaded on the three trays 40 to the bottom of the three sets of visual inspection components 20 for visual inspection. This method effectively improves inspection efficiency and saves manual labor.

[0025] In some embodiments, the visual inspection component 20 includes a bracket 201 and a visual camera 202; the bracket 201 is fixedly disposed on the top of the base 10, the visual camera 202 is fixedly disposed on the bracket 201, and the visual camera 202 is electrically connected to the inspection computer 50.

[0026] In practice: When the vision inspection component 20 performs visual inspection on the bearings loaded on the tray 40, the vision camera 202 on the bracket 201 captures images of the bearings. The vision camera 202 then transmits the captured bearing images to the inspection computer 50, which compares the bearing images with pre-stored standard bearing images to determine if the bearings have any appearance defects. This setup allows the vision inspection component 20 to effectively perform appearance inspection of the bearings.

[0027] In some embodiments, the lead screw module 30 includes a base plate 301, a drive motor 302, a ball screw 303, and a bearing seat 304; the drive motor 302 is fixedly disposed at one end of the base plate 301, the bearing seat 304 is fixedly disposed at the other end of the base plate 301, the output end of the drive motor 302 is drivenly connected to one end of the ball screw 303, and the other end of the ball screw 303 is rotatably connected to the bearing seat 304; a material tray 40 is drivenly connected to the ball screw 303.

[0028] In specific implementation: When the lead screw module 30 moves the material tray 40 to the bottom of the vision inspection component 20, the drive motor 302 drives the rotation of one end of the ball screw 303, and the other end of the ball screw 303 is supported by the bearing seat 304. When the ball screw 303 rotates, it drives the material tray 40 to move linearly, so that the material tray 40 corresponds to the bottom of the vision inspection component 20. With this setting, the lead screw module 30 can effectively drive the material tray 40 to move to the bottom of the vision inspection component 20, so that the bearings mounted on the material tray 40 can be captured and inspected by the vision inspection component 20.

[0029] In some embodiments, a nut seat 401 is provided at the bottom of the material tray 40, and a sliding groove 4011 is provided on both sides of the bottom end of the nut seat 401; a slide rail 3011 is provided on both sides of the base plate 301, and the sliding grooves 4011 on both sides of the bottom end of the nut seat 401 are slidably connected to the slide rails 3011 on both sides of the base plate 301; and the ball screw 303 is threadedly connected to the nut seat 401 at the bottom of the material tray 40.

[0030] In specific implementation: When the drive motor 302 drives the ball screw 303 to rotate, the ball screw 303 can thread-drive the nut seat 401 to move linearly. When the nut seat 401 moves linearly, the sliding grooves 4011 on both sides of the bottom end of the nut seat 401 slide on the sliding rails 3011 on both sides of the base plate 301 to achieve linear guidance of the nut seat 401. When the nut seat 401 is driven by the ball screw 303 to move linearly, the nut seat 401 also moves the material tray 40 linearly, so that the material tray 40 reaches the bottom end of the vision inspection component 20 during linear movement. With this setting, when the drive motor 302 drives the ball screw 303 to rotate, the ball screw 303 can effectively drive the material tray 40 to move to the bottom end of the vision inspection component 20.

[0031] In some embodiments, a control panel 101 is provided on the side of the base 10. The control panel 101 has several control keys 1011 and is electrically connected to the vision inspection component 20 and the lead screw module 30, respectively.

[0032] In practice: the control buttons on the control panel 101 are for manual operation by the user to control the operation of the vision inspection component 20 and the lead screw module 30. This configuration allows the user to conveniently control the operation of the vision inspection component 20 and the lead screw module 30.

[0033] In some embodiments, a plurality of rollers 102 are distributed on the bottom of the base 10.

[0034] In practice: when the user needs to move the bearing visual inspection device 100, they only need to manually push the base 10, which in turn allows the rollers 102 at the bottom of the base 10 to rotate, thus moving the bearing visual inspection device 100. This design makes the bearing visual inspection device easy for the user to move.

[0035] In some embodiments, a placement plate 103 is fixedly connected to the side of the base 10, and the detection computer 50 is located on the placement plate 103.

[0036] In practice: the testing computer 50 is placed on the placement plate 103 on the side of the base 10, so that when performing bearing appearance inspection on the base 10, the user can operate the testing computer 50 at close range to assist in completing the inspection. This setting makes the testing computer 50 easy for the user to operate.
