Description

Technical Field

[0001] This utility model relates to the field of oil seal production technology, and in particular to an oil seal lip spring detection device. Background Technology

[0002] In the existing oil seal manufacturing industry, springs are commonly used to reinforce the lip of the oil seal to enhance its sealing performance. By continuously applying radial force to the lip, the spring effectively compensates for sealing gaps caused by material wear or fluctuations in operating conditions, thereby significantly enhancing the reliability and service life of the seal.

[0003] However, accurate installation of the lip spring is a prerequisite for ensuring its effectiveness. During the later assembly process, defects such as missing springs, extra springs (multiple springs), or installation damage (e.g., wire drawing) will directly lead to substandard oil seals, subsequently causing serious quality problems such as early oil leakage and equipment failure. Therefore, inspecting the assembly condition of the lip springs before the oil seals leave the factory is an indispensable and critical step in the production process.

[0004] Currently, the industry mainly relies on contact conductivity detection and sensor-based induction detection for testing oil seal lip springs, both of which have the following drawbacks: The contact conductivity detection method is considered to have a "spring present" because the circuit is conductive as long as one spring is present. However, it cannot distinguish between two or more springs (multiple springs) when they are mistakenly installed, and will be incorrectly judged as a qualified product. At the same time, it cannot detect the wire breakage of the spring itself and has no ability to detect the quality of the spring. Sensor-based induction detection is similar to contact detection. As long as the sensor detects a metal signal, it determines that there is a spring. However, it cannot distinguish the quantity and quality of the springs, and therefore cannot determine whether the product is qualified. Utility Model Content

[0020] Please see Figures 1 to 3 The oil seal lip spring testing device includes: a support platform 8 capable of supporting and rotating the oil seal lip spring, a rotary station capable of rotating the spring, and a camera testing component for taking pictures of the spring.

[0021] Specifically, the first is the support platform 8, which is stably supported by the support plate 1. It can not only stably place the oil seal lip spring to be tested, but also cooperate with the subsequent claw structure to achieve the orderly flow of the spring.

[0022] Secondly, there is a rotary workstation, including a rotary platform 12, a rotary spindle 9, and a rotary motor 3. The rotary platform 12 is located at the center of the support platform 8, and the center of the rotary platform 12 is connected to the top of the rotary spindle 9. The output end of the rotary motor 3 is connected to the bottom of the rotary spindle 9 for transmission.

[0023] To ensure the stable operation of the rotary motor 3, a motor fixing plate 2 is provided below the rotary platform 12. The motor fixing plate 2 is connected to the bearing platform 8 by at least four support columns 5. The four support columns 5 are arranged in a rectangular shape to ensure that the motor fixing plate 1 is subjected to uniform force and further ensures the transmission stability.

[0024] Based on the above structure, the bearing platform 8 is provided with at least one set of claws 7 on both sides for clamping the oil seal lip spring and moving it to the rotary station, as well as transferring the spring after inspection from the rotary station to the unloading area.

[0025] Furthermore, the claw 7 is an adjustable claw, and its clamping specifications can be adapted to oil seal lip springs of different sizes. Different sizes of claws can be replaced according to the inner diameter of the spring to be tested, thereby achieving stable clamping of springs with different outer diameters and effectively improving versatility.

[0026] Furthermore, there is a camera-based image detection component used to perform visual detection of springs on a rotating workstation. This component includes a detection camera 17, a light source 16 that provides illumination for the detection camera 17, and a multi-dimensional adjustment unit for adjusting the detection positions of the detection camera 17 and the light source 16.

[0027] Furthermore, the multi-dimensional adjustment unit includes left and right slides 4, upper and lower slides 6, and front and rear slides 10. The upper and lower slides 6 are mounted on the left and right slides 4, and the front and rear slides 10 are mounted on the upper and lower slides 6. Through the cooperation of the three slides, the positions of the detection camera 17 and the light source 16 in the X, Y, and Z dimensions can be adjusted to the optimal detection position according to the size of different springs.

[0028] In order to achieve stable installation of the detection camera, a camera fixing plate 13 is provided on the front and rear slides 10, and the detection camera 17 is connected to the camera fixing plate 13 through a camera fixing seat 14.

[0029] To ensure the relative position of the light source and the detection camera is stable, a light source fixing plate 15 is provided on the front and rear slides 19, and the light source 16 is mounted on a light source fixing seat 11, which is connected to the light source fixing plate 15.

[0032] The working process of this utility model oil seal lip spring detection device is as follows: After the device is started, the adjustable claws 7 located on both sides of the bearing platform 8 clamp the oil seal lip spring to be tested according to the preset action, and transfer and place it on the rotating platform 12 of the rotating station. After the product positioning is completed, the rotary motor 3 starts and drives the rotary platform 12 and the oil seal lip spring on it to rotate at a constant speed through the rotary spindle 9. At the same time, the detection camera 17, with the help of the light source 16, collects images of the rotating product lip area. After the photo is taken, the rotary motor 3 stops, the claw 7 moves again, clamps the product that has been inspected, removes it from the rotary platform 12, and transfers it to the corresponding transfer area according to the inspection result (pass / fail) (such as qualified products flowing out or unqualified products being rejected). Finally, the claw 7 returns to its initial position, ready for the next operation.

[0033] The beneficial effects of this utility model oil seal lip spring detection device are: By introducing camera vision inspection, the accuracy of inspection is achieved through the synergy and multi-dimensional flexible adjustment of industrial CCD cameras and ring shadowless light sources, fundamentally overcoming the inherent defects of traditional contact and sensor-based inspection methods.
