Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing technology, specifically to an automatic SMT solder paste spraying machine. Background Technology

[0002] SMT (Surface Mount Technology) is an abbreviation for a series of processes performed on a PCB (Printed Circuit Board). SMT is a popular technology and process in the electronics assembly industry. During the placement process, an automatic solder paste sprayer is used to apply solder paste. However, existing SMT automatic solder paste sprayers do not have limiters for the circuit board; if the circuit board moves during the spraying process, the spraying position will deviate. Utility Model Content

[0003] The purpose of this invention is to provide an automatic SMT solder paste spraying machine, which solves the problem that existing automatic SMT solder paste spraying machines do not limit the circuit board, and the spraying position will deviate if the circuit board moves during the spraying process.

[0004] Technical solution

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic SMT solder paste spraying machine, comprising a placement plate, two side plates fixedly connected to the side of the placement plate, a slide rail fixedly connected between the two side plates, a movable ring slidably connected to the surface of the slide rail, an electric telescopic rod fixedly connected to the lower surface of the movable ring, a spraying mechanism fixedly connected to the bottom end of the electric telescopic rod, a placement groove formed on the upper surface of the placement plate, grooves formed on the inner walls of the left and right sides of the placement groove, springs fixedly connected to the inner walls of the two grooves, and limit blocks fixedly connected to the opposite ends of the two springs.

[0006] Furthermore, the lower surface of the placement plate is provided with a movable hole that communicates with the interior of the placement slot, and a push rod is movably connected inside the movable hole.

[0007] Furthermore, a movable plate is fixedly connected to the bottom end of the top rod, and a spring is fixedly connected to the upper surface of the movable plate.

[0008] Furthermore, the top end of the spring is fixedly connected to the lower surface of the placement plate.

[0009] This utility model provides an automatic SMT solder paste spraying machine. It has the following beneficial effects:

[0010] This automatic SMT solder paste spraying machine uses the interaction of placement slots, limiting blocks, grooves, and springs to facilitate the positioning of circuit boards. The interaction of springs, movable holes, push rods, and movable plates facilitates the upward lifting of the processed circuit boards for easy removal. This solves the problem of existing automatic SMT solder paste spraying machines that do not limit the circuit board position, causing misalignment during spraying if the circuit board moves.
