High-precision chip mounting head capable of flight identification

Abstract

The invention provides a high-precision chip mounting head capable of flight identification. The chip mounting head comprises a chip mounting head support, chip mounting shafts mounted in the chip mounting head support, a direction-Z elevation mechanism, a direction-R turning mechanism and a vacuum module group; the chip mounting head is characterized in that an integrated control assembly is mounted in the back side of the upper portion of the chip mounting head support, the vacuum module group is mounted in the front side of the upper portion of the support, a direction-R stepping motor which drives the direction-R turning mechanism and a CCD camera collecting images are mounted in the middle of the front side of the support, direction-Z driving motors are mounted in the back side of the support, and the directions of output shafts of the direction-Z driving motors are vertical to the axis-Z; and a flight camera device is mounted in the lower portion of the back side of the chip mounting head support, and comprises a light source assembly below a nozzle, a camera assembly, a camera support provided with the light source assembly and the camera assembly and a driving mechanism which enables the camera support to move along the axis-X, and an acute angle is formed between the direction of a lens of the camera assembly and the vertical direction in the XY plane. The chip mounting head is minimized and low-cost, and stable, accurate, rapid and high-precision chip mounting is realized.

Description

technical field [0001] The invention relates to a placement head, in particular to a placement head with high precision and flight recognition function. Background technique [0002] At present, there are many kinds of placement machines, but whether it is a fully automatic high-speed placement machine or a manual low-speed placement machine, its overall layout is similar. The automatic placement machine is a high-precision automation equipment that is controlled by a computer and integrates optics, mechanics and electronics. The identification system is composed of sensors and computer control system, which includes the functions of picking-displacement-positioning-placement, etc., and realizes the fast and accurate placement of SMD components. As an important part of the whole machine, the placement head of the placement machine is very critical to the performance of the whole machine. After picking up the components, the placement head can automatically correct the posit...

Problems solved by technology

Both of the above-mentioned latest technologies have obvious defects. One will limit the number of identifiable nozzles, and the other is more complex in optical path matching, and both of them are costly, and the size of the patch head is relatively large. Therefore, a simple structure, miniaturization, Low-cost placement heads with flight recognition function urgently need to be developed
