Description

Technical Field

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

[0002] A placement machine, also known as a "mounting machine" or "surface mount system," is located after a dispensing machine or screen printer in a production line. It accurately places surface mount components on PCB pads by moving a placement head. These machines are available in both manual and fully automatic versions. Conventional placement machines often fail to accurately or incorrectly position components on printed circuit boards, often leading to processing errors.

[0003] For example, patent application number CN202110191231.5 discloses a flexible circuit board placement machine. The invention enhances the fixing effect of the circuit board, reduces the possibility of its position deviation during the placement process, and improves the accuracy of the components in the placement process to a certain extent, thereby improving the product qualification rate. Through five sets of cylinders and nozzles, the material can be sucked and placed continuously, which improves the continuity of the placement and the speed of placement. To a certain extent, the work efficiency of the placement is improved, the pressure on the circuit board during the placement process is reduced, and the possibility of the circuit board being crushed is reduced, which reduces the production cost to a certain extent. During use, when the circuit board is being placed, because the designated position of the circuit board cannot be placed, positioning errors or positioning is not accurate enough, resulting in processing errors.

[0004] For example, patent application number CN202122706938.3, the utility model provides a flexible circuit board placement machine, which relates to the technical field of placement machines. The utility model fixes the flexible circuit board on a pad, and then moves the support plate so that the first slider slides inside the first slide groove, so that the support plate can move up and down at will, thereby facilitating the movement of the support plate, and then the clamping block clamps the flexible circuit board inside the engaging groove to fix it. By moving the second slider, the second slider slides inside the second slide groove, and then the connecting rod drives the clamping block to move, so that the engaging groove and the flexible circuit board are more stably engaged, thereby facilitating the operation of the placement machine and improving the stability and work efficiency of the device. During use, when performing placement work on the circuit board, positioning errors or inaccurate positioning usually occur because the specified position of the circuit board cannot be placed. This causes processing errors. Utility Model Content
