Description

Technical Field

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

[0002] Chip mounter: also known as "chip placer" and "Surface Mount System", in the production line, it is configured after the dispensing machine or screen printer, and is a device that accurately places surface mount components on the PCB pads by moving the placement head.

[0003] When producing and processing computer main boards, a chip mounter is needed to perform chip placement on the computer main boards. When using a chip mounter to produce and process computer main boards, first, the main board needs to be conveyed to the chip placement position, and then the chip placement mechanism is used to perform chip placement processing on the main board.

[0004] For example, the Chinese patent publication number "CN211063895U" in the prior art provides a chip mounter for main board production and processing, including a bottom plate. On both sides of the upper surface of the bottom plate, a sleeve and a sliding rod are respectively fixed. The upper surface of the bottom plate is rotatably connected with a threaded rod located inside the sleeve. The top end of the threaded rod is sleeved with a driven wheel. The outer wall of the sleeve is fixed with a first motor. The output end of the first motor is fixed with a driving wheel. The driving wheel is in transmission connection with the driven wheel through a belt. A through hole is opened on the left side of the sleeve. A first slider is threadedly connected to the threaded rod. A second slider is slidably connected to the sliding rod. A moving plate is fixed between the first slider and the second slider. One side of the moving plate is fixed with a fixed block. The top end of the fixed block is rotatably connected with a second driven wheel.

[0005] Compared with traditional chip mounters, this device can perform chip placement on two main boards simultaneously, greatly improving the production efficiency and facilitating popularization.

[0006] For the existing chip mounters for main board production and processing, after the main board moves below the chip mounter head, the placement is not stable enough and is prone to shaking, and no stable setting is carried out, which is not conducive to chip placement on the main board. Moreover, according to the different chip placement positions on the main board surface, the chip placement position of the main board cannot be adjusted. Content of the Utility Model
