Automatic solder robot

Abstract

The invention relates to an automatic solder robot comprising a soldering bit, an X-axis module, a Y-axis module, a Z-axis module, a carrying board, a wire feeding mechanism and an electric control box as well as a soldering bit motion mechanism and an accurate solder wire positioning mechanism. The soldering bit motion mechanism comprises a moving device which is connected with the soldering bit and comprises a connecting block, an air cylinder, a sliding plate and a linear sliding rail; the connecting block is used for connecting the upper end of the soldering bit with the cylinder body of the air cylinder together and connected with the sliding plate which is glidingly connected with the linear sliding rail; a solder wire nozzle of the accurate solder wire positioning mechanism is connected with the connecting block through a connecting rod, the connecting block is connected with a connecting shaft which is fixedly connected with a deflection block and is in rotating connection with an elevation block, a clamping block is connected with the elevation block and fixed at the upper end of the soldering bit, a horizontal adjusting screw is in rotating connection with the deflection block, and the front end of the horizontal adjusting screw is glidingly connected with the elevation block. The invention can accurately solder melted tin solder in a needed position and improve the efficiency, the product quality consistency and stability.

Description

technical field [0001] The invention relates to an automatic soldering robot. Background technique [0002] Automatic soldering technology has attracted more and more attention because it can solve the low-quality and low-efficiency problems of manual soldering due to human factors. The soldering machine is mainly used for tinning on PCB boards with electronic components inserted Let the liquid tin stick to the insertion hole of the PCB board on the tin surface of the tin furnace, so that the electronic components can be soldered to the PCB board. Soldering machines mainly include immersion welding machines and wave soldering machines: 1. Immersion welding machines, which are about to fix the container for storing tin liquid, let the circuit board move downward, so that the welding surface reaches below the surface of the tin liquid, so as to achieve soldering the goal of. The disadvantage of this is that if the circuit board is moved up and down, it is prone to short circ...

The control of the gimbal arm with this structure is not precise and stable enough

The soldering iron head of the automatic soldering robot disclosed in Japanese patent document JP 3226370 is controlled by an up-down direction movement mechanism and a left-right direction movement mechanism, which can control the position of the soldering iron head more accurately. The soldering iron head with this structure cannot deflect the angle and is still not flexible enough

At the same time, there is an obvious defect in the above two kinds of soldering equipment: when the soldering iron head moves to the soldering working position for soldering, it will rise to move to the next soldering working position, so when performing a large number of soldering at the same horizontal working position , the soldering iron head still needs to be driven by the universal arm or the up and down movement mechanism, so that on the one hand, it is difficult to control the small travel distance accurately, on the other hand, the frequent movement of the universal arm or the up and down movement mechanism is easy to cause wear and affect the service lif
