An inspection workbench for smt steel mesh production

Abstract

The invention discloses an inspection workbench for SMT steel mesh production, which comprises a workbench, a feed box is fixed on the upper end of the workbench, and a lower pressing part is arranged on the feed box. A second cylinder is fixed on the upper end of the workbench, and a push plate is fixed on the side end of the second piston rod on the second cylinder, and the push plate can push the steel mesh onto the fixture. A bracket is fixed at the side end of the fixing member, a lamp bead board is fixed on the bracket, and a plurality of lamp beads are arranged on the lamp bead board. The present invention presses the steel mesh to the bottom of the feeding box through the lower pressing part after feeding, and then drives the second cylinder to push the steel mesh into the fixing part with the push plate, basically realizing the automatic operation, and the steel mesh after fixing The net is directly under the light, effectively using the light, and the inspection effect is better; at the same time, the distance between the stencil and the light is designed in the present invention, and when the distance is closer, the stencil can be inspected more clearly.

Description

technical field [0001] The invention relates to the field of SMT stencils, in particular to an inspection workbench for SMT stencil production. Background technique [0002] SMT stencil is a special mold for SMT. Its main function is to aid in the deposition of solder paste, the purpose is to transfer the exact amount of solder paste to the exact location on the empty PCB. After the stencil is produced, it is necessary to test the mesh of the stencil to prevent the stencil from missing printing or lack of tin during use, which will affect product quality and production efficiency. [0003] In the prior art, with the development of science and technology, and with the miniaturization of electronic product components, the openings of SMT stencils are getting smaller and smaller. Hole clogged. In the existing inspection of blocked holes by light, when the steel mesh is inspected in batches, the labor intensity is increased. When the blocked holes are small and cannot be disp...

AI Technical Summary

Problems solved by technology

After the stencil is produced, it is necessary to test the mesh of the stencil to prevent the stencil from missing printing or lack of tin, which will affect product quality and production efficiency.

[0003] In the existing technology, with the development of science and technology, and with the miniaturization of electronic product components, the openings of SMT stencils are getting smaller and smaller. The phenomenon of clogging

In the existing inspection of blocked holes by light, when the steel mesh is inspected in batches, the labor intensity is increased. When the blocked holes are small and cannot be displayed by light irradiation, the steel mesh needs to be moved to a closer distance to the light. Observing in different places is time-consuming and labor-intensive
