A Laser Template Polishing Fixture

Abstract

The invention discloses a laser template polishing fixture which comprises a rack, a template lifting device and template clamping devices.An empty cavity is formed in the rack; a fixing plate is transversely arranged in the rack; the template lifting device comprises a central transfer block, a threaded rod and a template containing unit; the template lifting device is vertically arranged in the center of the rack; the upper portion of the threaded rod is connected with a template containing box in a threaded mode, and the lower portion of the threaded rod is connected in a threaded hole formed in the middle of the central transfer block in a threaded mode; the template clamping devices are distributed at the four corners of the upper end face of the rack and comprise the lower end face clamping devices and the upper end face clamping devices.The laser template polishing fixture has the advantages that the template is lifted to a certain height through the template lifting device and then fixed at the height through the template clamping devices, therefore, the template can be suspended over the rack, and great convenience is brought to the subsequent polishing work.

Description

technical field [0001] The invention relates to the technical field of SMT laser templates, in particular to a laser template polishing fixture. Background technique [0002] In the process of SMT laser stencil production, when the stainless steel sheet is laser cut, there will be burrs and oxides on the hole wall, which will seriously affect the quality of SMT laser stencil printing solder paste and cannot meet customer requirements. In order to solve this problem, the hole wall of the steel sheet after laser cutting must be processed. The treatment method is electrochemical polishing process. In order to perform electrochemical polishing, a polishing jig must be used, and the laser-cut steel sheet must be mounted on the polishing jig, so that it can cooperate with the polishing equipment to complete the electrochemical polishing. [0003] In the existing SMT laser template manufacturing process, the fixture is usually fixed by screws. The disadvantage is that an addition...

Problems solved by technology

[0005] The existing technology realizes the automatic clamping of the SMT laser template through the gear system, which saves the time waste caused by manual participation and improves work efficiency. However, this solution is to tightly attach the SMT laser template to the fixture plate, so that The lower end surface of the SMT laser template is in a non-exposed state. If the lower end surface of the SMT laser template needs to be polished later, then the SMT laser template should be turned over again, which will cause a waste of time and increase the cost.
