Description

Technical Field

[0001] The invention relates to the field of PCB circuit board production, in particular to a chip mounting table and a chip mounting machine. Background Art

[0002] The placement machine is also called the placement machine or surface mount system. In the production line, it is configured after the dispensing machine or screen printing machine. It is a device that accurately places surface mount components on the PCB pads by moving the placement head. The placement machine is used to achieve high-speed, high-precision and fully automatic placement of components. It is the most critical and complex equipment in the entire SMT production. The placement machine is the main equipment in the SMT production line. The placement machine has developed from the early low-speed mechanical placement machine to the high-speed optical alignment placement machine, and has developed towards multi-functional, flexible connection modularization.

[0003] The existing patent (CN103635030B) is a new type of chip mounter platform and chip mounter, including a platform, a Y-axis moving device arranged on the platform, an X-axis moving device connected to the Y-axis moving device and driven by the Y-axis moving device to move in the Y-axis direction of the platform, and a chip mounter head connected to the X-axis moving device and driven by the X-axis moving device to move in the X-axis direction of the platform, wherein the platform is polished from stone as a whole. The chip mounter platform and the chip mounter are provided with a chip mounter head, which can move in the X-axis direction and the Y-axis direction, so as to realize the chip mount processing of the electronic circuit board by the device. Although the device can reduce the overall difficulty of the chip mount work, the platform is polished from stone, has low strength, is easy to break when used, is heavy, and does not move. The chip mounter has only one chip mounter head, which is difficult to adapt to the needs of processing multiple circuit boards at the same time, and cannot effectively improve the overall work efficiency of the chip mount work.
