Description

Technical Field

[0001] This utility model relates to the field of shock absorber dust cover testing technology, specifically to a shock absorber dust cover light transmittance testing device. Background Technology

[0002] In the production of automotive shock absorbers, a dust cover (such as...) needs to be installed around the piston rod of the shock absorber. Figure 5 As shown, a dust cover protects critical components of the shock absorber from external environmental factors. The dust cover includes a corrugated tubular cover 14 and a reinforcing ring 15 located at the bottom of the cover 14. After the dust cover is injection molded, the light transmittance of the cover 14 needs to be tested. The light transmittance test aims to verify whether there are any defects or pinholes in the cover 14 within its circumference. These defects not only affect the appearance of the product but also adversely affect the function of the dust cover.

[0003] While the widely used manual visual inspection method in the industry can visually identify some obvious defects, it relies heavily on the operator's experience, making the results susceptible to individual influences and leading to inconsistent inspection standards. This increases the difficulty of controlling product consistency. Some manufacturers also use vision camera inspection solutions, which require specific light sources for the dust covers during visual inspection. However, lighting conditions in the workshop are not constant, especially when ambient light mixes with the inspection light source. Ambient light can interfere with the inspection, thus affecting its accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a device for detecting the light transmittance of a shock absorber dust cover, which can replace manual inspection of the dust cover, improve the consistency of inspection, reduce the interference of external light on visual inspection, and improve the accuracy of inspection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a light transmittance testing device for a shock absorber dust cover, comprising a machine base and a vision camera testing assembly. The machine base is provided with a sealed chamber, and an operating port is provided on one side of the sealed chamber. A light transmittance testing mechanism is provided inside the sealed chamber. The light transmittance testing mechanism includes a cover rotation assembly, a light source lifting assembly, and the vision camera testing assembly that cooperates with the cover rotation assembly. The cover rotation assembly includes a placement seat for vertically placing the cover, and the light source lifting assembly includes a light source located above the placement seat. The light source can be inserted into the vertically placed cover.

[0006] A further improvement of this utility model is that the light source lifting assembly includes a horizontal plate, a telescopic rod is vertically provided on one side of the horizontal plate, the horizontal plate is fixedly mounted on the telescopic end of the telescopic rod, and the light source is located at the lower end of the horizontal plate.

[0007] A further improvement of this utility model is that the light source lifting assembly further includes a shielding plate, which is disposed on one side of the horizontal plate and can shield the operating port after the light source lifting assembly descends.

[0008] A further improvement of this utility model is that the cover rotation assembly includes a motor disposed at the lower end of the placement seat and driving it to rotate.

[0009] A further improvement of this utility model is that the upper end of the placement base is provided with a positioning port that cooperates with the reinforcing ring of the dust cover.

[0010] A further improvement of this invention is that the inner wall surface of the sealed chamber is an opaque surface with low reflectivity.

[0011] A further improvement of this utility model is that guide rods are vertically provided on both sides of the horizontal plate, and the horizontal plate is slidably connected to the guide rods through a connector.

[0012] A further improvement of this utility model is that the light source is a strip-shaped light-emitting element, and the length of the strip-shaped light-emitting element does not exceed the length of the cover.

[0013] A further improvement of this utility model is that the operating port is located on one side of the sealed chamber, one side of which is a personnel operating position, and the other side of which is provided with the placement seat.

[0014] A further improvement of this utility model is that photoelectric sensors are provided outside the sealed chamber on both sides of the operating port. The photoelectric sensors are electrically connected to the telescopic rod. When the photoelectric sensors detect an object, the shield cannot be lowered.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes a rotating cover assembly, a lifting light source assembly, and a visual camera detection assembly, which work together to replace manual inspection of the dust cover, improving the consistency of inspection. By setting up a sealed chamber, it reduces the interference of external light on visual inspection, thereby improving the accuracy of inspection.

[0017] This invention incorporates a cover rotation component. By placing the dust cover on a mounting base and rotating the base, the dust cover rotates, enabling the vision camera inspection component to perform 360° inspection of the product. This reduces blind spots and improves the accuracy and efficiency of the inspection.

[0018] This invention, by setting up a light source lifting component, enables the light source to be raised and lowered. Compared to fixing the light source in a fixed position inside a sealed chamber, the light source can be inserted into the dust cover and emit light inside the dust cover, making defects on the dust cover more obvious, facilitating the detection of small flaws, and improving the accuracy of detection.

[0019] This invention can shield the operating port by setting a baffle plate, reducing the interference of external light on the detection. Furthermore, the baffle plate and the light source are raised and lowered by the same telescopic rod, achieving synchronous operation and improving resource utilization.

[0020] The operating port of this utility model is located on one side of the sealed chamber. One side of this side is the operator's position, and the other side of this side is provided with a placement seat. In actual use, it can facilitate workers to place or take the dust cover, improve detection efficiency, and detect through photoelectric sensors to avoid the shield from pinching hands, thus improving the safety of use.

Detailed Implementation

[0027] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1: Combination Figures 1-5It is understood that a light transmittance testing device for a shock absorber dust cover includes a machine base 1 and a vision camera testing component 2. The machine base 1 has a sealed chamber 3, with an operating port 4 on one side. A light transmittance testing mechanism is located inside the sealed chamber 3. The light transmittance testing mechanism includes a cover rotation component, a light source lifting component, and the vision camera testing component 2, which cooperates with the cover rotation component. The cover rotation component includes a mounting base 5 for vertically placing the cover, and the light source lifting component includes a light source 6 located above the mounting base 5. The light source 6 can be inserted into the vertically placed cover. The vision camera testing component 2 is a conventional vision camera testing component for visual inspection in the prior art, and this utility model does not involve any improvement thereto.

[0029] The light source lifting assembly includes a horizontal plate 7, with a telescopic rod 8 vertically mounted on one side of the horizontal plate 7. The horizontal plate 7 is fixedly mounted on the telescopic end of the telescopic rod 8, and the light source 6 is mounted at the lower end of the horizontal plate 7.

[0030] The light source lifting assembly also includes a shielding plate 9, which is located on one side of the horizontal plate 7 and can block the operation port 4 after the light source lifting assembly descends. Preferably, the horizontal plate 7 is also provided with side plates on both sides. The side plates cooperate with the shielding plate 9 to surround and block the three sides of the light source, thereby improving the accuracy of detection.

[0031] The cover rotation assembly includes a motor 10 disposed at the lower end of the placement base 5 and driving it to rotate. Preferably, the table surface of the machine tool is provided with a through hole, and the motor 10 is disposed below the table surface, with its output shaft passing through the through hole and connected to the placement base 5.

[0032] The upper end of the placement base 5 is provided with a positioning opening 11 that mates with the reinforcing ring of the dust cover. The positioning opening 11 is a recess provided on the placement base 5, which mates with the reinforcing ring of the dust cover to position it. Preferably, the depth of the recess is less than the height of the reinforcing ring to avoid the recess obstructing the cover body of the dust cover.

[0033] The inner wall of the sealed chamber 3 is an opaque, low-reflectivity surface. This opaque, low-reflectivity surface reduces the likelihood of light emitted from the light source within the chamber being reflected back by the chamber walls. The low-reflectivity surface helps prevent light from being reflected back by the chamber walls, thus avoiding false readings or affecting test accuracy.

[0034] Preferably, the inner wall of the sealed chamber 3 is a black, opaque surface. Black is the color that absorbs light the most, and it can effectively absorb light of various wavelengths. This helps to prevent light from the light source inside the bellows from being reflected back by the chamber wall, causing false readings or affecting the accuracy of the test.

[0035] Guide rods 12 are vertically provided on both sides of the horizontal plate 7, and the horizontal plate 7 is slidably connected to the guide rods 12 through a connector. Preferably, the connector is a slider, and the slider is connected to the side plate.

[0036] Light source 6 is a strip-shaped light-emitting element, and the length of the strip-shaped light-emitting element does not exceed the length of the cover.

[0037] The operating port 4 is located on one side of the sealed chamber 3. One side of this side is the personnel operating position, and the other side of this side is provided with a placement seat 5.

[0038] Photoelectric sensors 13 are installed outside the sealed chamber 3 on both sides of the operating port 4. The photoelectric sensors 13 are electrically connected to the telescopic rod 8. When the photoelectric sensors 13 detect an object, the baffle 9 cannot descend. The photoelectric sensors are conventional photoelectric sensors in the prior art. An invisible network of light beams can be formed at the operating port using these sensors. If a hand or other object passes through these light beams, the sensor will immediately detect it and send a signal to prevent the baffle 9 from moving.

[0039] The working principle of the shock absorber dust cover light transmittance detection device provided by the utility model is as follows: In use, the dust cover is placed into the sealed chamber 3 through the operation port 4. The dust cover is positioned and placed vertically through the placement seat 5. The telescopic rod 8 is activated, which drives the horizontal plate 7 to descend, thereby driving the shielding plate 9 to block the operation port 4 and simultaneously driving the light source 6 to descend and insert into the dust cover. Then, the light source 6 and the motor 10 are activated. The motor 10 drives the dust cover to rotate at a constant speed. At this time, the visual camera detection component 2 can continuously capture images from multiple angles during the rotation of the dust cover, thereby covering the entire circumferential surface and realizing a comprehensive detection of the dust cover body.
