Problems solved by technology

If we follow the traditional positioning method relying on gravity, the deformation size and direction of each device's mounting frame will be infinitely magnified under a 170 times microscope during laser edge sealing, resulting in a deviation of the coordinates of each device relative to the zero point of the housing after positioning More than 0.3mm, and the positioning accuracy of laser edge sealing requires a deviation of no more than 0.02mm, otherwise the device’s sealing performance will be unqualified due to the deviation of the laser track, and the traditional gravity positioning method can no longer meet the precise positioning of the contactor in laser welding technology
[0004] The current gravity positioning method is to support the bottom surface of the edge-sealing contactor of the L-shaped mounting frame with a fixture. Due to the influence of the resistance welding deformation of the L-shaped mounting frame, the deviation after positioning and locking is relatively large

Embodiment Construction

[0024] Herein, the technical solutions provided by the present invention will be further introduced in detail with reference to the accompanying drawings and specific embodiments.

[0025] In order to solve the problem that the existing gravity positioning method has low positioning accuracy and cannot meet the precise positioning of the contactor in the laser welding technology, the present invention provides a gravity-removing positioning method with an L-shaped mounting frame contactor. The method Position the edge contactor with the L-shaped mounting bracket so that the bottom surface is suspended.

[0026] The positioning method can be implemented by any positioning fixture. The specific steps are to first position the edge-to-be-sealed contactor with the L-shaped mounting bracket in the fixture, and then lift the edge-to-be-sealed contactor with the L-shaped mounting bracket. The bottom surface is suspended in the air to complete the positioning, and then the edge is wel...

Abstract

The invention provides a gravity-removing positioning method and a positioning jig for a contactor with an L-shaped mounting frame. When positioning the contactor to be sealed with an L-shaped mounting frame, the bottom surface of the contactor is suspended. In the invention, the bottom surface of the contactor to be sealed with the L-shaped mounting frame is positioned in the air, and the welding surface after the matching of the cover and the base is directly positioned, thereby improving the precision of the laser focal length in the welding process; The influence of welding deformation on the positioning accuracy ensures precise positioning; the positioning accuracy deviation ranges from 0.01 to 0.04 mm, and the positioning accuracy is increased by more than 10 times.

Description

technical field [0001] The invention relates to an edge banding fixture, in particular to a gravity-removing positioning method with an L-shaped mounting frame contactor and a positioning fixture. Background technique [0002] With the rapid development of my country's military science and technology, the overall sealing quality level of military sealed electronic components is getting higher and higher. Since the positioning accuracy of the sealing device directly determines the accuracy of the laser operation, the precise positioning of the laser sealing of the components is required. put forward higher requirements. In particular, some sealed devices with special installation methods, such as contactors with L-shaped mounting brackets, such as figure 1 As shown, the structure of the L-shaped mounting bracket is as follows figure 2 shown. [0003] At present, the installation method of the contactor mounting frame is mainly realized by laser welding technology. The spec...
