Automatic shearing and welding integrated machine for pins of circuit boards

Abstract

The invention discloses an automatic shearing and welding integrated machine for pins of circuit boards. The automatic shearing and welding integrated machine comprises an auxiliary box, a main box body and a lower cutting box, an injection box is fixedly arranged at the bottom end of the lower cutting box, a tin liquid cavity is formed in the injection box, an injection supporting rod cavity witha downward opening is formed in the upper end of the tin liquid cavity, an injection lead screw cavity with a downward opening is formed in the upper end of the injection supporting rod cavity, an injection motor with a rightward rotating shaft is fixedly arranged in an injection motor cavity, and the rotating shaft of the injection motor is an injection lead screw. According to the automatic shearing and welding integrated machine, pin shears are connected to a tin liquid injection device, so that the pin shearing process is automatic, meanwhile, tin liquid injection can be automatically conducted on the positions where the pins need to be sheared by utilizing protrusions of the pins, the manual tin soldering process is reduced, the welding efficiency of the circuit boards is improved, the labor cost and the financial cost are lowered, meanwhile, the integrated machine is handheld, small and convenient to carry, use and store, and the manufacturing cost of the integrated machine is also lowered.

Description

technical field [0001] The invention relates to an all-in-one machine for automatically cutting off and welding circuit board pins, and mainly relates to the technical field of circuit boards. Background technique [0002] After the circuit board is installed, there are often pins. In order to prevent electric shock and comply with IPC standards, these pins must be removed. At the same time, before cutting the pins, the circuit board also needs to be soldered. These two steps are carried out separately. Separate devices and steps are required, but both are indispensable, but the two steps must be separated and independent, which is very troublesome to carry out separately. In fact, the two can be combined into one in the process of welding and cutting corners. [0003] In summary, the sand mold shearing pin and the welding process are independent, but both are indispensable, and can be combined, which is improved by the present invention.
