DETAILED DESCRIPTION

[0029] The technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0030] Embodiment one With reference to Figures 1 to 3 The embodiments of the present application disclose an automobile glass lifter 3 detection device, comprising: A positioning base plate 2 is arranged obliquely on the workbench 1, and the positioning base plate 2 is provided with a positioning mechanism 21 for fixing the automobile glass lifter 3; A movable mounting conversion mechanism 4 is disposed in front of the positioning base plate 2 and is used to mount the oiling assembly 6 and the simulated glass load 5 on the glass bracket 31 of the automobile window lifter 3 in a predetermined sequence. The oiling assembly 6 is used to apply lubricant to the slide rail 32 of the automobile window lifter 3 that is adapted to the glass bracket 31 while the automobile window lifter 3 is in operation, following the movement of the glass bracket 31. The lifting speed detection mechanism 7 is used to monitor the speed of the load 5 driven to rise by the glass bracket 31 when the automobile window lifter 3 is in operation.

[0031] Among them, reference Figures 1 to 3 The positioning substrate 2 is arranged obliquely on the workbench 1, providing an inclined operating plane for the entire detection process, which is convenient for simulating the actual working state of the automobile window lifter 3; the mobile mounting conversion mechanism 4 is fixed in front of the positioning substrate 2, and the oiling assembly 6 and the simulated glass load 5 are mounted on the glass bracket 31 of the automobile window lifter 3 according to the set sequence, realizing the functions of oiling and simulating the load 5, improving the automation level of the detection and reducing manual operation; the speed detection mechanism 7 is used to monitor the speed of the load 5 driven by the glass bracket 31 when the automobile window lifter 3 is running, so as to judge whether the performance of the automobile window lifter 3 meets the requirements.

[0032] Specifically, refer to Figures 2 to 4 The positioning base 2 is provided with a positioning mechanism 21 for securing the automobile window lifter 3. This positioning mechanism 21 includes a clamping jaw 212 positioned on the positioning base 2 at a predetermined position. A clamping base 211 is provided on the positioning base 2. The middle portion of the clamping jaw 212 is hingedly connected to the clamping base 211, and the rear portion of the clamping jaw 212 is hingedly connected to the operating end of a first electric telescopic rod 213. The clamping jaw 212 is generally made of a high-strength metal material, such as stainless steel, to ensure sufficient strength and durability. The shape of the clamping jaw 212 is designed to fit the automobile window lifter 3. The clamping portion at the front end can closely fit the surface of the automobile window lifter 3 to prevent the lifter from shaking during the inspection process. The first electric telescopic rod 213 can be hydraulic or electric, and it provides power to the clamping claw 212. When the first electric telescopic rod 213 is extended or retracted, it drives the clamping claw 212 to rotate around the hinge point of the clamping seat 211, so that the clamping part at the front end of the clamping claw 212 fixes the automobile window lifter 3 on the positioning seat provided on the positioning base 2; the positioning seat can be a groove or protrusion with a specific shape, which is adapted to the bottom shape of the automobile window lifter 3, further improving the accuracy of positioning.

[0033] Reference Figures 2 to 4The combined logic of the positioning mechanism 21 is realized by the telescopic action of the first electric telescopic rod 213, which drives the clamping jaw 212 to rotate around the clamping seat 211 to fix the automobile glass lifter 3. This combined mode makes the positioning process more stable and reliable, and can effectively avoid inaccurate detection results caused by the movement of the lifter during detection. The combined effect is to firmly fix the automobile glass lifter 3 on the positioning base plate 2, providing a stable basis for subsequent oiling and load 5 detection. The reason for this combined effect is that the clamping jaw 212 is reasonably designed and the first electric telescopic rod 213 is accurately controlled, so that the clamping force can uniformly act on the lifter, ensuring the stability of the positioning.

[0038] With reference to Figures 5 to 7, the combination logic of the moving mounting conversion mechanism 4 is to realize the two-dimensional movement of the sliding table 42 by the horizontal moving assembly 411 and the vertical moving assembly 412, realize the reverse movement of the first support frame 45 and the second support frame 46 by the reverse mechanism 47, and control the movement distance of the first support frame 45 by the abutting piece 48; the combination mode makes the oil coating assembly 6 and the load 5 be accurately mounted on the glass cradle 31 of the automobile glass lifter 3 according to the set sequence. The combination effect is to improve the automation degree of the oil coating and the load 5 mounting, and reduce the error of manual operation. The reason for the combination effect is that the precise cooperation and transmission relationship between the components make the whole moving mounting process more efficient and accurate.
