Description

Pcb bonding pad welding auxiliary device Technical Field The utility model relates to the technical field of pcb bonding pad welding, in particular to a pcb bonding pad welding auxiliary device. Background The bonding pad is a basic component unit of surface mounting assembly and is divided into a surface mount type and a through hole type, wherein when the through hole type bonding pad is connected with components, the components are usually connected in a wave soldering mode, but in the wave soldering process, the height of an electronic component is limited to a certain extent, if the size of the component is too large, the component cannot pass wave soldering, or the electronic component is too close to the edge of the board, the edge of the equipment is touched, normal soldering is affected, and therefore, partial components are suitable for manual soldering treatment. In the manual welding process, firstly, components are required to be inserted into a through hole bonding pad and then welded from the back of a circuit board, in order to improve the working efficiency, workers often directly support the components from the back of the circuit board, namely the bottom of the circuit board, and then directly weld the components, but part of tin liquid drops from the through hole to cause harm to hands of the workers, so that the pcb bonding pad welding auxiliary device is provided for solving the problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a pcb bonding pad welding auxiliary device, which solves the problems in the background art. In order to achieve the purpose, the pcb bonding pad welding auxiliary device comprises a mounting frame, a servo motor and an electric push rod which are respectively and fixedly arranged on two sides of the mounting frame, wherein a first clamping frame and a second clamping frame are respectively arranged on output shafts of the servo motor and the electric push rod, elastic clamping modules are respectively arranged on inner sides of the first clamping frame and the second clamping frame, and the pcb bonding pad welding auxiliary device further comprises: The positioning module comprises an I-shaped sliding block arranged on the first clamping frame and the second clamping frame and a guide pillar fixedly arranged on the I-shaped sliding block, wherein a pressing plate is arranged on the outer surface of the guide pillar, a spring column is arranged on the pressing plate, and the spring column is used for positioning components by pressing the pressing plate. Optionally, the elastic clamping module comprises telescopic springs fixedly arranged on the upper side and the lower side of the inner cavities of the first clamping frame and the second clamping frame, and clamping plates fixedly connected to the other ends of the telescopic springs. Optionally, the self-locking device further comprises a self-locking assembly, wherein the self-locking assembly comprises a ratchet bar fixedly installed on one side of the I-shaped sliding block and a second adjusting groove formed in the pressing plate, and an interference bar is movably arranged in the second adjusting groove.
