Problems solved by technology

[0002] In the reproduction of digital tubes, it is necessary to put the pins on the circuit board, fix the chip on the circuit board, bake, inspect, glue, and general inspection, and connect the positive and negative electrodes by welding. During this process, circuit boards often appear The weak fixation leads to poor welding accuracy, the problem of virtual welding or excessive solder joints, which greatly affects the product quality of the digital tube.

Abstract

The invention belongs to the technical field of Nixie tube manufacturing, and particularly relates to a clamping device for Nixie tube pin welding. The clamping device comprises a left clamping plate,a right clamping plate and connecting rods. Adjusting sleeves are arranged on the right clamping plate. The adjusting sleeves are arranged in a thread manner on the right clamping plate. End portionsof the connecting rods are arranged in a thread manner in the left clamping plate and are arranged in the adjusting sleeves in a smooth manner. Springs are also arranged between the left clamping plate and the right clamping plate. The tops of the springs are connected to the left clamping plate and the right clamping plate. The connecting rods are also provided with connecting rod retaining rings thereon for restricting the outward movement of the adjusting sleeves. The clamping device in the invention is convenient to use, achieves the clamping of a Nixie tube PCB with different shape structures through coarse adjustment and fine adjustment, has a wide range of use and good clamping stability, and thus ensures the precision and consistency of welding quality.

Description

technical field [0001] The invention belongs to the technical field of digital tube production and manufacturing, and in particular relates to a clamping device for welding digital pins. Background technique [0002] In the reproduction of digital tubes, it is necessary to put the pins on the circuit board, fix the chip on the circuit board, bake, inspect, glue, and general inspection, and connect the positive and negative electrodes by welding. During this process, circuit boards often appear Insufficient fixation leads to poor welding accuracy, false welding or excessive solder joints, which greatly affects the product quality of the digital tube. Contents of the invention [0003] In view of this, the present invention aims to provide a clamping device for digital pin welding to solve the problems in the prior art and ensure the goodness and stability of the welding quality of the digital tube PIN pins. [0004] In order to achieve the above object, technical solution ...
