Positioning cutting mechanism and high-precision chip mounter

Abstract

The invention relates to the technical field of chip mounters, and in particular relates to a positioning cutting mechanism and a high-precision chip mounter. The positioning cutting mechanism comprises a connecting plate; connecting protrusions are integrally formed at the left end and the right end of the connecting plate; the connecting protrusions and the chip mounter body are fixedly mountedthrough bolts; the left end and the right end of the connecting plate are fixedly provided with an unwinding device and a winding device through bolts correspondingly; the unwinding device and the winding device are fixedly provided with winding drum driving motors through bolts correspondingly; and the output ends of the winding drum driving motors drive winding drums facilitating installation ofreinforcing sheet strips. The beneficial effects are that: the positioning cutting mechanism of the chip mounter can use a straightener to straighten a reinforcing sheet strip, and then use a conveying device and a cutting device to automatically position and cut the reinforcing sheet; and in addition, the device can cut reinforcing sheets of different shapes by replacing different cutting templates, so that the reinforcing requirements of different chip mounting operations are met, and the automation degree and usability of the chip mounter are greatly improved.

Description

technical field [0001] The invention relates to the technical field of placement machines, in particular to a positioning and cutting mechanism of a high-precision placement machine. Background technique [0002] Since the circuit board needs to be disassembled and cut in various ways during the design process of the circuit board, areas with low strength are prone to appear on the circuit board. These areas are prone to breakage during future use and affect normal operations. The chip machine installs the corresponding shape of the reinforcement sheet through the patch operation at the corresponding position. The existing reinforcing sheets generally need to be cut and formed on the reinforcing sheet strip according to the different circuit boards to be installed, but the cutting mechanism on the traditional placement machine can only cut one shape of the reinforcing sheet. It is difficult to be effectively applied to the reinforcement and placement of different circuit bo...

Problems solved by technology

The existing reinforcing sheets generally need to be cut and formed on the reinforcing sheet strip according to the different circuit boards to be installed, but the cutting mechanism on the traditional placement machine can only cut one shape of the reinforcing sheet. It is difficult to be effectively applied to the reinforcement and placement of different circuit boards, and due to the lack of a corresponding straightening mechanism for the reinforcement sheet, the reinforcement sheet is still prone to bending after cutting, which affects the reinforcement sheet. installation quality
