Problems solved by technology

[0003] In order to improve the accuracy of the center position of tiny components, a common method is to design a side positioning mechanism on the fixture. However, due to the large size tolerance of the substrate of tiny components, the center position accuracy produced by the side positioning method still cannot meet the test requirements.

Abstract

The invention provides a central locating mechanism and device, and relates to the technical field of locating of micro parts. The central locating mechanism comprises a power mechanism, a cam mechanism, a base, elastic parts and clamping parts, wherein the cam mechanism comprises a cam and at least two driven parts oppositely arranged on the edge of the outer side of the cam; an output end of thepower mechanism is in transmission connection with a rotating shaft of the cam; the base is erected above the cam; at least two oppositely arranged connecting seats are arranged on the base; each connecting seat is connected with one driven part; the clamping parts which extend in the direction away from the base are arranged on the connecting seats; the elastic parts are arranged on the connecting seats; and the driven parts abut the edge of the outer side of the cam under the action of the elastic parts, and the clamping parts move towards the center to clamp a to-be-detected product. According to the central locating mechanism, precision of a central position of the to-be-detected product can be improved, and stability and reliability of testing data acquisition are guaranteed.

Description

technical field [0001] The present application relates to the technical field of positioning of tiny parts, in particular to a center positioning mechanism and equipment. Background technique [0002] In the process of optical testing of micro components, whether the selection of positioning reference is reasonable or not determines the accuracy of the center position of micro components, and the accuracy of the center position of micro components affects the stability and reliability of test data collection. [0003] In order to improve the accuracy of the center position of tiny components, a common method is to design a side positioning mechanism on the fixture. However, due to the large size tolerance of the substrate of tiny components, the center position accuracy produced by the side positioning method still cannot meet the test requirements. . Contents of the invention [0004] In view of this, the purpose of the present application is to provide a center position...
