Suction nozzle device for welding head of chip mounting equipment

Abstract

The invention relates to a suction nozzle device for a welding head of chip mounting equipment, which is applied to the technical field of suction nozzles on a chip mounter, and comprises a connecting arm, a fixing block fixed on the connecting arm and a suction nozzle rod vertically arranged in the fixing block, wherein an L-shaped cavity is formed in the fixing block, the suction nozzle rod is fixed in a vertical section of the cavity, an air pipe is connected with the horizontal section of the cavity in a sealed mode, and two clamping plates are integrally arranged on the fixing block; and the suction nozzle rod sequentially penetrates through the space between the two clamping plates to be inserted into the cavity, bolts are arranged on the clamping plates in a penetrating mode, and the suction nozzle rod is fixed to the fixing block by rotating the bolts. The suction nozzle device has the advantages that the air pipe is perpendicular to the suction nozzle rod, so that the position of the suction nozzle rod can be observed conveniently, the suction nozzle rod is clamped and fixed by the two clamping plates, and when the suction nozzle rod inclines, the suction nozzle rod can be disassembled and assembled quickly and again conveniently.

Description

technical field [0001] The present invention relates to the technical field of the suction nozzle on the placement machine, more specifically, it relates to a suction nozzle device used for the welding head of the placement equipment. Background technique [0002] The placement machine is also called "mounting machine" and "surface mount system". In the production line, it is configured after the dispensing machine or screen printing machine, and the surface mount components are accurately placed on the PCB by moving the placement head. A device on a pad. The fully automatic placement machine picks up chips and other mounted components pneumatically and places them on the PCB. [0003] Such as Figure 5 As shown, a suction nozzle device of an existing SMT equipment welding head includes a fixed block 3 fixed on the SMT equipment body, a suction nozzle rod 2 placed in the fixed block 3, and a suction nozzle rod 2 placed on the fixed block. Air pipe 42, the air pipe is conne...

Problems solved by technology

[0004] Since the nozzle rod is used to pick up and mount components, the mounted components are arranged in a horizontal array, so the nozzle rod must be set up vertically. One end of the nozzle rod is used to pick up the mounted components, and the other end is used to connect the air pipe. Due to the high accuracy of placement, the position accuracy of the nozzle rod will also be very high. It is necessary to check the position of the nozzle rod frequently. During the inspection process, the trachea needs to be pulled out, and the nozzle rod can only be seen through the light. Whether it is in the center position, the disassembly and assembly of the air pipe will affect the efficiency of inspection, and at the same time, it will need to stop, which will affect the processing efficiency
