Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically a multi-degree-of-freedom detection device. Background Technology

[0002] Inspecting the produced workpieces is one of the important processes in the production process. Traditional inspection is done manually, which requires a large number of experienced workers. However, errors can still occur during the production process, resulting in a decrease in the quality of the produced workpieces.

[0003] Traditional testing devices mainly consist of a base, a testing platform, sensors, a mechanical transmission mechanism, a control system, and a data processing unit. The base provides stable support; the testing platform carries the workpiece; the sensors collect physical quantity signals; the mechanical transmission mechanism drives the movement of the testing components; the control system coordinates the operation of each module; and the data processing unit analyzes the signals and outputs the results. During testing, the workpiece is first placed on the testing platform. The testing program is set through the control system, and the mechanical transmission mechanism drives the sensors to move along a preset path. The data processing unit compares and analyzes the results with standard values, ultimately generating a test report to complete the testing of items such as dimensional accuracy or defects.

[0004] In high-precision testing scenarios for 3C products, due to the small size and complex structure of components, multiple platforms are required to achieve multi-station linkage testing. This places high demands on the positioning accuracy of the platforms. To obtain multi-directional features of the workpiece, the platform needs to rotate the material at multiple angles to meet the multi-viewpoint testing requirements. However, traditional testing devices are limited by mechanical structure. When adjusting multiple angles, operators need to manually operate knobs or wrenches to adjust the tilt angle and rotation position of the material one by one. This is not only time-consuming but also relies on human experience. Uneven force and reading deviations can easily lead to angle positioning errors. Frequent manual adjustments can also reduce the stability of the platform. Especially when testing multiple batches of materials, the cumulative error will significantly affect the consistency of the test data. Utility Model Content

[0033] Reference Figures 2-4 An adjusting plate 62 is fixedly installed on the outer circumferential surface of the positioning rod 4. Two parallel guide grooves 63 are opened on the adjusting plate 62. An electrode plate is fixedly installed on the inner wall of the guide groove 63.

The fixing plate 22 is used to store and fix the material to be detected. Operation begins when the fixing plate 22 is moved directly below the detection rod 9. When the operator starts the reducer 61, it drives the adjusting frame 7 to rotate laterally. Then, by controlling the reducer 71, the adjusting frame 8 rotates longitudinally, thereby controlling the multi-angle tilt of the detection rod 9 to achieve multi-directional detection of the material. The positional relationship between the adjusting frame 7 and the adjusting frame 8 ensures that the device will not jam during operation. When the adjusting frame 7 rotates, the connecting plate 73 drives the slide rod to slide along the guide groove 63, thereby controlling the contact point between the slide rod and the electrode plate. During the movement of the slide rod, the lighting lamp 3 can adjust its illumination intensity according to the tilt angle of the detection rod 9, making it easier for the operator to observe it.
