Description

Technical Field

[0001] This utility model relates to the field of ignition coil testing technology, specifically a testing device for factory testing of ignition coils. Background Technology

[0002] As a core component of the automotive engine ignition system, the ignition coil's performance and stability directly affect the engine's power output, fuel economy, and emissions. Conducting comprehensive quality testing on the ignition coil before it leaves the factory is a crucial step in ensuring the reliability of the entire vehicle. The testing mainly includes the integrity of its appearance, the accuracy of its structural dimensions, and the consistency of its assembly.

[0003] The CN115569854B publication discloses a testing device for factory testing of ignition coils. The marking gear and fixed toothed plate work together to move a marking pen, causing one end of the pen to contact the side wall of the ignition coil, thus marking the coil. Compared to common ignition coil testing devices, this device can separately mark the recesses and protrusions on the side wall of the ignition coil, making it easier for the operator to adjust the coil based on the markings. Furthermore, the device is simple and convenient to operate, saving the operator a significant amount of time.

[0004] The testing equipment used for factory testing of ignition coils can clamp and fix the ignition coils through the clamping ring. However, the curvature of the inner side of the clamping ring cannot be adjusted, so the clamping ring can only clamp the same type of ignition coil. When it is necessary to clamp ignition coils of other sizes, the equipment needs to be replaced, which affects the work efficiency. Therefore, it needs to be improved. Utility Model Content

[0028] The rotating mechanism 2 includes a fixed plate 22, which is fixedly connected to the left and right sides of the top of the processing table 1. A first hydraulic cylinder 21 is fixedly connected to the left side of the fixed plate 22, and a moving table 201 is fixedly connected to the right side of the first hydraulic cylinder 21. A limit rod 29 is slidably connected to the inner side of the moving table 201, and the limit rod 29 is fixedly connected to the inner side of the fixed plate 22. Vertical plates 27 are fixedly connected to the front and rear sides of the top of the moving table 201. A second hydraulic cylinder 26 is fixedly connected to the outer side of the vertical plate 27. A fixed frame 202 is fixedly connected to the inner side of the second hydraulic cylinder 26. A servo motor 28 is fixedly connected to the inner side of the fixed frame 202. A rotating shaft 203 is fixedly connected to the inner side of the servo motor 28. A rotating plate 24 is fixedly connected to the inner side of the rotating shaft 203. A support member 204 is fixedly connected to the outer side of the rotating plate 24. A V-shaped clamp 23 is fixedly connected to the inner side of the rotating plate 24. A sliding rod 25 is fixedly connected to the outer side of the fixed frame 202.

[0029] Furthermore, there are two limiting rods 29, which are fixedly connected to the front and rear sides of the inner side of the fixed plate 22 respectively. The limiting rods 29 can limit the movement of the moving platform 201, making the moving platform 201 more stable during movement.

[0030] Furthermore, there are two slide rods 25. The two slide rods 25 are fixedly connected to the outside of the fixed frame 202, and the two slide rods 25 are slidably connected to the inside of the vertical plate 27. The slide rods 25 can limit the fixed frame 202, making the fixed frame 202 more stable during the back and forth movement.

[0031] Furthermore, a circular groove corresponding to the movement trajectory of the support member 204 is provided on the inner side of the fixed frame 202, and the support member 204 is slidably connected to the inside of the circular groove. Through the circular groove, the support member 204 can rotate inside the fixed frame 202, and the support frame can support the rotating plate 24.

[0032] Furthermore, the ignition coil body 4 is disposed inside the V-shaped clamp 23, and the outer side of the ignition coil body 4 is in close contact with the inner side of the V-shaped clamp 23. The V-shaped clamp 23 can clamp and fix the ignition coil body 4, making the ignition coil more stable during the testing process.

[0033] Example 2

[0034] Please see Figure 1-4 Furthermore, based on Embodiment 1, the detection mechanism 3 includes a connecting frame 33, which is fixedly connected to the front and rear sides of the processing table 1. A camera 32 is fixedly connected to the inner side of the connecting frame 33, a lighting lamp 31 is fixedly connected to the top of the inner side of the connecting frame 33, and a support column 34 is fixedly connected to the bottom of the connecting frame 33.

[0036] In actual operation, when this device is used to test the ignition coil body 4, the ignition coil body 4 is first placed inside the V-shaped clamp 23. The second hydraulic cylinder 26 is turned on. By controlling the extension and retraction of the second hydraulic cylinder 26, the second hydraulic cylinder 26 drives the fixing frame 202 and the inner V-shaped clamp 23 to move synchronously until the inner side of the V-shaped clamp 23 is tightly attached to the outer side of the ignition coil body 4, thus completing the clamping and fixing of the ignition coil body 4.

[0037] According to the testing requirements, the position of the moving platform 201 can be adjusted by the first hydraulic cylinder 21. The moving platform 201 slides along the limit rod 29, driving the clamped ignition coil body 4 to move to the right. The two cameras 32 inside the connecting frame 33 take multi-angle pictures of the ignition coil body 4 during the rotation process from the top and the back. The lighting lamp 31 provides sufficient light to ensure the clarity of the pictures. The appearance and related parameters of the ignition coil body 4 can be tested by the image information captured by the camera 32.

[0038] When it is necessary to rotate the ignition coil body 4, the servo motor 28 is started. The servo motor 28 drives the rotating shaft 203 and the rotating plate 24 to rotate, so that the ignition coil body 4 fixed by the V-shaped clamp 23 rotates synchronously, so that the camera 32 can capture and detect the other positions of the ignition coil body 4.

[0039] The image information captured by camera 32 can be used to inspect the appearance and related parameters of the ignition coil body 4, realizing the automated inspection process of the ignition coil body 4 before leaving the factory. Camera 32 model: RVC-I5140.
