Terminal and its high-precision manufacturing method

Abstract

The invention provides a terminal and a high-precision manufacture method thereof. According to the invention, the problems that the low final terminal product precision can not conform to the subsequent production requirement because each assembly line production program of the traditional terminal has errors can be solved. The terminal comprises a flakey body, wherein the body is provided with an extruded part and a bending part used for assisting a product to be clamped. The high-precision manufacture method for the terminal comprises the following manufacture steps: 1) pushing materials into a die; 2) stamping a positioning hole; 3) trimming to cause the material to be subjected to scalarization; 4) cutting the product shape; and 5) detecting a formed product. The terminal and the high-precision manufacture method for the terminal aim at the high-precision requirement on the terminal in the subsequent moulding injection molding processing, the traditional terminal production method is improved, a series of processing flows of feeding, punching, trimming, cutting the shape, carrying out buoyancy lift, guiding the position and detecting are subjected to targeted modification one by one, the modification step is practical and effective, and the high-precision level of the final finished product of the terminal is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of electronic component processing, and relates to a terminal product and its production method, in particular to a terminal and its high-precision manufacturing method. Background technique [0002] With the rapid development of my country's social economy and technology, the technology of electronic products is becoming more and more technological and advanced, and people are more inclined to the demand direction of multiple functions, concentrated performance and convenient portability. Therefore, the physical development trend of electronic products is smaller and smaller, more sophisticated and integrated. Therefore, all the important electronic components inside are also developing towards the direction of thin, small and light, and require high precision at the same time. [0003] In order to match the development of one mold with multiple holes of the mold, and to consider the high precision of the ...

AI Technical Summary

Problems solved by technology

[0004] In the current industry, there are errors in the various assembly line production procedures of the terminal, which leads to the low precision of the final terminal product and cannot meet the subsequent production requirements.

The errors in each production procedure are as follows: Firstly, the width of the materials purchased each time is inconsistent, which leads to an excessive gap between the feeding and positioning, which affects the accuracy of shearing and punching; further affects the size of the shearing edge

Then, because the gap between the positioning hole and the positioning pin is 0.01mm, which has exceeded the required tolerance of the terminal product, it is impossible to carry out plastic injection molding production

The appearance of the re-cut product is processed by light bending grinding. The stripping insert and the lower mold insert required for the processing are each divided into 5 pieces and assembled, and this assembly form is a necessary condition for the light bending grinding processing method, but The assembly of each piece of parts brings a processing error of + / -0.002~0.003mm, thus forming the accumulation of processing errors of the whole part. Obviously, the precision of the products processed by this method is poor and does not meet the requirements.

Finally, use a 50x microscope to measure the size of the finished product, resulting in poor finished product size due to measurement errors
