A kind of SMT step template welding method and device

Abstract

The invention relates to the technical field of welding equipment, in particular to a method and device for welding an SMT ladder template, including processing equipment, the inner top surface of the processing equipment is fixedly connected with a positioning slide rail, and the front surface of the positioning slide rail is internally slidably connected There is a positioning slider, the left and right sides of the positioning slider are movably connected with a crank connecting rod, the lower surface of the positioning slider is fixedly connected with a laser head, and the lower front surface of the crank connecting rod is movably connected with a Auxiliary turntable, by ensuring that the working thickness is different, the distance between the positioning slider and the workpiece surface is the same, so as to ensure the normal operation of the equipment, thereby increasing the use range of the equipment, thereby improving the working efficiency of the equipment, and purifying the irritating gas. So as to avoid polluting the environment, and at the same time accelerate the flow rate of the gas on the surface of the workpiece, so that the temperature on the workpiece will be lowered, so that the warping and deformation of the workpiece can be well prevented, and the workpiece can be well protected.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an SMT step template welding method and device. Background technique [0002] With the progress of SMT, the requirements for SMT templates are also getting higher and higher. Because the electronic components soldered on a circuit board are different, and different components have different requirements for the thickness of tin, the requirements for different components are different. The SMT template undergoes local thinning or local thickening, resulting in a "step" on the template. [0003] However, the existing equipment cannot well control the height of the laser head according to the thickness of the SMT step template, which may cause the laser head to cause breakdown of the work, which may cause the waste of the workpiece, and can not be well adjusted to the equipment. The generated thermal effect is processed, which may cause the warpage and deformation of the ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing equipment cannot control the height of the laser head well according to the thickness of the SMT step template itself, which may cause the laser head to cause a breakdown of the work, which may cause waste of workpieces, and it cannot properly control the equipment. The thermal effect produced may cause warping and deformation of the workpiece, affecting the use of the work, and at the same time, the irritating gas cannot be processed well; therefore, those skilled in the art provide a SMT step template welding method and device, To solve the problems raised in the above-mentioned background technology
