Description

Technical Field

[0001] The utility model relates to the technical field of circuit board welding foot cutting equipment, in particular to a circuit board welding foot cutting device. Background Art

[0002] In order to facilitate the cutting of circuit board soldering feet, it is often necessary to use circuit board soldering foot cutting equipment. The utility model patent with patent application number CN202120063799.4 discloses an integrated circuit board soldering foot cutting machine. The integrated circuit board is fixed by the cooperation of the provided clamping blocks, and then the angle of the connecting plate is rotated by the second motor, the electric lifting rod is contracted, and then the electric slide moves on the first slide slot to cut the soldering feet of the integrated circuit board. In this process, the soldering feet can be cut without the staff touching the integrated circuit board, which avoids injuries to the staff's fingers. In the cutting process, the ejection range of the soldering feet is limited by the baffle, and then part of the soldering feet are directly cut through the through hole. Into the dust box, after cutting, the staff only needs to use a tool to sweep the welding feet at the edge of the baffle into the through hole, which avoids the welding feet from scattering everywhere and is very easy to clean, thereby improving the use efficiency of the welding foot cutting machine. According to the technical scheme disclosed by it, when using the existing circuit board welding foot cutting device, on the one hand, it is unable to effectively control the clamping force of the circuit board, which may easily cause damage to the circuit board due to the large force, or looseness during cutting due to insufficient clamping force, which is not conducive to ensuring the cutting quality of the circuit board welding feet. On the other hand, when cutting the circuit board welding feet, it is easy to cause the circuit board to be unevenly placed due to the inconsistent height of the devices on the circuit board, which is not conducive to ensuring the uniform cutting thickness of the circuit board welding feet.
