Automatic placement machine

Abstract

The invention discloses an automatic chip mounter, which comprises a plate loading mechanism, a feeding mechanism, an element taking and mounting mechanism, a vision system and a control system, wherein the plate loading mechanism is used for loading, positioning and unloading a PCB (printed circuit board); the feeding mechanism is used for automatically primarily sorting, positioning, directionally correcting and unloading electronic elements in bulk; the element taking and mounting mechanism comprises a first taking head and is used for controlling the first taking head to rotate and to move horizontally and vertically; the control system is used for positioning the PCB and the electronic elements on the first taking head through the PCB mounting position and the position information of the first taking head collected by the vision system, so that the electronic elements can be accurately mounted on the corresponding positions on the PCB. By adopting the automatic chip mounter, the mechanical operation range can be greatly shortened, the process flow can be simplified, and the mechanical efficiency can be improved.

Description

technical field [0001] The invention relates to the field of surface mounting, in particular to an automatic placement machine. Background technique [0002] The placement machine is one of the key equipment in the SMT (Surface Mounted Technology) industry. Its main function is to quickly and accurately place the integrated electronic components on the corresponding pads on the PCB. In the contemporary electronics industry, the main technical indicators to measure the performance of placement machines are speed and accuracy. [0003] At present, commonly used automatic placement machines include: mechanical system, vision system and control system. The mechanical system and vision system work through the command of the control system. The mechanical system can be regarded as the body of the placement machine, which provides the placement machine The working platform includes various mechanisms to complete the functions of the placement machine, such as the board loading mec...

Problems solved by technology

[0004] In the above technical solution, the invalid action of the placement machine is large, especially, the suction path of the electronic components is large, resulting in low mechanical efficiency of the placement machine, and under this condition, the requirements for mechanical hardware are relatively high, which increases the cost; in addition , the existing placement machine must first tape the electronic components through the feeder, and only the components that meet the requirements of the tape can be uniformly absorbed by the paste head, which increases the transfer process and increases the cost
