Description

Technical Field

[0001] This utility model belongs to the technical field of film cutting devices, and in particular relates to a film cutting device used in PCB laminating machines. Background Technology

[0002] The film cutting device in a PCB laminating machine is mainly used for high-precision cutting and bonding of cover film, protective film or adhesive materials during the production of printed circuit boards (PCBs).

[0003] Traditional circular blade cutting of dry film involves rotating a circular blade and moving it linearly to make contact cuts. During cutting, film debris is generated and falls onto the product, causing poor film pressing and affecting the film pressing yield. Utility Model Content

[0004] The purpose of this invention is to provide a film cutting device for PCB laminating machines, which solves the problem that traditional circular blades cut dry film by rotating and moving linearly to make contact cuts. During the cutting process, film debris is generated and falls onto the product, causing poor lamination and affecting the lamination yield.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a film cutting device for a PCB laminating machine, comprising a cutting mechanism and a laser head. The cutting mechanism includes two sets of supporting plates, with a connecting rod fixedly connected between the two sets of supporting plates. A mounting base is slidably connected to the periphery of the connecting rod. A supporting plate is fixedly connected to one end of the mounting base, and a mounting plate is fixedly connected to the top of the supporting plate. The laser head is mounted on the mounting plate. A connecting plate is fixedly connected to one side of each of the two sets of supporting plates. A transmission wheel is rotatably connected to the upper surface of the connecting plate. A transmission belt is installed between the two sets of transmission wheels, and the three together form a belt pulley transmission structure. The mounting base is located on the periphery of one end of the transmission belt and is fixedly connected to the transmission belt.

[0007] A crossbar is fixedly connected between the two sets of support plates. The crossbar is located above the connecting rod and at the bottom of the mounting plate, and slides with the mounting plate.

[0008] A servo motor is mounted on the bottom of one of the connecting plates, and the output end of the servo motor is fixedly connected to one of the transmission wheels.

[0009] A baffle is fixedly connected to the other side of the support plate, and the baffle is set on one side of the mounting plate; by setting the baffle, the mounting seat is prevented from moving excessively and colliding with the support plate, thereby improving the safety of the device.

[0010] This utility model has the following beneficial effects:

[0011] This invention features a cutting mechanism and a laser head. A servo motor drives a transmission wheel to rotate, which in turn drives a belt pulley transmission structure to slide the mounting base on a connecting rod. This causes the mounting plate to slide on a crossbar, which in turn moves the laser head to perform the film cutting operation. The invention uses laser cutting of dry film and heat-melting cutting, which does not produce film debris and improves the film pressing yield.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
