Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a chip mounter for circuit board processing. Background Art

[0002] Surface mount technology is an assembly technology that directly attaches and solders surface-mount components to specified positions on the surface of a printed circuit board. It has the characteristics of high assembly density, small size and light weight of electronic products, high reliability, strong vibration resistance, low solder joint defect rate, and good high-frequency characteristics. It can reduce electromagnetic and radio frequency interference, easily realize automation, improve production efficiency, reduce costs by 30% to 50%, and save materials, energy, equipment, manpower and time. In surface mount technology SMT, a circuit board placement machine is required.

[0003] The Chinese patent with the announcement number CN216218578U discloses a chip placement machine for processing integrated circuit boards, including a workbench, with side panels connected to the left and right sides of the top surface of the workbench, and a chip placement structure is provided at the lower ends of the two side panels close to each other. Four adjustment grooves are provided on the left and right sides of the top surface of the workbench, and the insides of the two groups of adjustment grooves are slidably connected to adjustment blocks through adjustment springs, and the upper ends of the two groups of adjustment blocks close to each other are provided with side grooves that penetrate the adjustment blocks longitudinally. The design of the adjustment blocks, when used in conjunction with the adjustment grooves, can adjust the distance between the adjustment blocks so that the adjustment blocks can be adjusted. It can clamp and fix PCB boards of different sizes horizontally, and the roller can clamp and fix the PCB boards vertically, so that the PCB boards are more stable during the patch process, reducing the possibility of affecting the normal patch process and the patch effect. However, after the above patent completes the patching of the circuit board, the staff needs to take out the circuit board and put the circuit board to be patched again before the operation can be carried out, which will waste a lot of time and greatly reduce the equipment's patching efficiency for the circuit board. Therefore, those skilled in the art provide a patch machine for circuit board processing to solve the problems raised in the above background technology. Utility Model Content
