Description

Technical Field

[0001] The utility model relates to the technical field of flexible disk detection, in particular to an automatic detection and anti-misoperation device for flexible disk assembly. Background Art

[0002] With the continuous strengthening of quality control by the host factory, we need to continuously explore and improve the corresponding quality inspection means and methods in on-site production.

[0003] On the flexible disk assembly production line, after assembly, the products need to be inspected to see if the gaskets are attached properly and whether the welding directions of the gear rings are correct. The inspection adopted is manual visual inspection. This method requires the operator to visually observe the workpiece to determine the correct welding direction of the gear ring and the proper attachment of the gasket by eyesight. The disadvantages are that it is impossible to ensure accurate inspection by visual observation, and in the long-term visual inspection process, visual fatigue may lead to overlooking defects and allowing them to pass. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides an automatic detection and anti-misoperation device for flexible disk assembly, which not only reduces the visual inspection time of operators, reduces the labor intensity, but also eliminates the need for operators to visually judge the results. Instead, the sensor automatically measures and outputs the results, improving the reliability of the detection.

[0005] In order to achieve the above object and other related objects, the technical solution provided by the utility model is as follows:

[0006] An automatic detection and anti-misoperation device for flexible disk assembly includes a base body, a vision sensor and a laser displacement sensor. The base body includes a support seat and support feet. The support seat is arranged above the support feet. A plurality of external bolt hole positioning columns are arranged on the outer circumference of the support seat. A workpiece support column is arranged between adjacent external bolt hole positioning columns.

A second anti-misoperation pin is arranged between adjacent internal bolt hole positioning columns. A first anti-misoperation pin is arranged on the outer circumference of the support seat. A connector is arranged at the bottom of the support seat. The connector is connected with a sensor bracket.

[0023] Embodiment: As Figure 1 or Figure 2 or Figure 3 shown, a flexible disk assembly automatic detection and anti-misalignment device includes a matrix 100, a vision sensor 201, and a laser displacement sensor 202. The matrix 100 includes a support base 109 and support feet 101. The support base 109 is provided above the support feet 101. A plurality of outer bolt hole positioning posts 102 are provided on the outer circumference of the support base 109. Workpiece support posts 106 are provided between adjacent outer bolt hole positioning posts 102. Special-shaped hole positioning blocks 103 are provided corresponding to the inner sides of the outer bolt hole positioning posts 102. Inner bolt hole positioning posts 104 are provided corresponding to the inner sides of the special-shaped hole positioning blocks 103.

[0031] Working principle: As Figure 4 shown, the assembly of the flexible frisbee includes a gasket 500, a gear ring 400, and a flexible disc 300. When the workpiece arrives at this process after the previous process is completed, the operator places the flexible frisbee on this device. At this time, the laser displacement sensor 202 will judge whether the gasket 500 is missing or overloaded by measuring the distance to the gasket 500, and output the result to the relay 1; when the operator presses the start button, the vision camera starts, and judges whether the direction of the gear ring 400 is correct by taking pictures of the workpiece image. When the direction is correct, it will output a pulse signal lasting for one second to start the operation of the next process. When the direction is incorrect, it will output a beep and will not start the operation of the next process.

[0032] In summary, the utility model not only reduces the visual inspection time of the operator and reduces the labor intensity, but also eliminates the need for the operator to visually judge the result. The sensor automatically measures and outputs the result, improving the reliability of the detection.
