Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a bearing image detection device. Background Art

[0002] As a basic precision component widely used in manufacturing equipment, once there are appearance defects such as pits and scratches on the surface of the bearing, it will affect the mechanical properties of the bearing. Therefore, the appearance detection of the bearing is very important. In the early stage, most of the appearance detections were carried out manually. By visually inspecting the appearance of each component of the bearing manually, this method not only requires a large amount of labor, but also it is difficult to guarantee the measurement accuracy.

[0003] The existing Chinese patent document CN202021563548.4, a bearing image detection device, is characterized in that: it includes a bearing clamp, a light source and a camera arranged on a workbench; the bearing clamp is used to clamp and position the bearing to be observed; the light source is used to irradiate the bearing to be observed; the camera is used to capture the reflection point of the bearing to the light source and identify the captured image through a processing system. The beneficial effect of the utility model is that: through the setting of the upper and lower two light sources, it is detected whether the bearing is facing upwards before entering the greasing process, avoiding misfinding the greasing point and causing poor greasing; at the same time, it can detect whether the steel balls are missing in the bearing to eliminate defective products.

[0004] However, there are certain defects in the use of the above patent. This device can only detect one bearing at a time and cannot detect multiple bearings in large quantities and continuously, so the working efficiency is relatively low. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a bearing image detection device.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A bearing image detection device includes a workbench and a display controller. A buffer area is provided at the upper right end of the workbench. A rework area and a finished product area are provided on the left side of the workbench, and the finished product area is arranged below the rework area;

[0008] Feeding channels are respectively provided at both ends of the buffer area. One end of the feeding channel extends into the buffer area and is communicated with it, and the other end extends out of the workbench. A first conveyor belt is provided on the left side of the buffer area. One end of the first conveyor belt extends into the buffer area, and the other end extends into the finished product area. A gravity sensor is provided on the first conveyor belt;

[0013] The detection device is fixed on the upper surface of the workbench, and the second conveyor belt penetrates through the inlet and outlet of the detection device.

[0014] Through the above technical solution, the camera inside the detection device cooperates with the lens to detect unqualified bearings for the second time, further analyze the reasons for the unqualified bearings and display them above the real controller. Finally, the unqualified bearings are sent to the rework area, and the workers can quickly and accurately find the reasons for the unqualified and make rectifications, greatly improving the working efficiency.

[0015] A rotating device is provided inside the buffer. The rotating device includes a motor. A rotating shaft is provided at the output end of the motor.

[0017] The shape of the push plate is "L" - shaped, and the push plate is directly below the gravity detector.

[0018] Through the above technical solution, the "L" - shaped push plate can limit the bearings and prevent the bearings from deviating from the route during the movement.

[0019] A baffle is provided between the first conveyor belt and the second conveyor belt, and a baffle is provided on the upper side of the second conveyor belt.

[0020] Through the above technical solution, the baffle ensures that the bearings can move along the established route and will not deviate from the conveyor belt.

[0021] The utility model has the following beneficial effects compared with the prior art:

[0022] 1. By setting a buffer zone and feeding channels above and below the buffer zone, feeding is carried out in a two-station manner.

A gravity sensor 42 is provided on the first conveyor belt 41; the bearing 33 is conveyed into the buffer 2 through the feeding channel 22. The setting of the buffer 2 is to prevent the problem of blockage caused by excessive one-time input of the bearing 33. The buffer 2 is set to be circular, and enclosures 21 are provided around it to ensure that the bearing 33 does not fall onto the workbench 1, causing the detection to stagnate.

[0032] Above the first conveyor belt 41, a second conveyor belt 4 is provided. The second conveyor belt 4 is arranged in parallel with the first conveyor belt 41. One end of the second conveyor belt 4 extends into the rework area 7;

[0033] At the lower end of the first conveyor belt 41, an electric hydraulic cylinder 8 is provided. The output end of the electric hydraulic cylinder 8 is provided with a push plate 81.

[0034] The gravity sensor 42 on the first conveyor belt 41 can detect the weight of the bearing 33 and can accurately screen out unqualified bearings 33.

[0035] As Figure 2 As shown, in order to further ensure the accuracy of the detection result and find out the cause of the problem, a detection device 6 is provided above the second conveyor belt 4. The detection device 6 includes a housing. At the top end inside the housing, a detection light source 61 is provided. On the side wall inside the housing, a fixed rod 62 is fixedly provided.
