Description

Technical Field

[0001] This utility model relates to the field of PCB film cutting technology, specifically a cutting device for PCB film production. Background Technology

[0002] PCB film is a key material used in the PCB manufacturing process. It mainly plays a role in pattern transfer, circuit protection, and manufacturing assistance. PCB film plays a vital role in the PCB manufacturing process. It is not only related to the accurate transfer of circuit patterns and the protection of circuits, but also directly affects the performance and reliability of the PCB.

[0003] In actual use, current PCB film cutting equipment typically cuts the PCB film directly with a cutting blade. Because the PCB film is thin, it may shift or be blown away by wind, leading to cutting failure or inability to cut. Therefore, improvements are needed. Summary of the Invention

[0004] This utility model provides a cutting device for PCB film production, which can be equipped with a drive mechanism to drive the pressure plate to gradually approach the conveyor belt, so that the pressure plate presses the PCB film on the conveyor belt, making the cutting knife more stable during cutting.

[0005] To achieve the above objectives, a cutting device for PCB film production is provided, comprising a mounting base, a conveyor belt fixedly mounted on the inner side of the upper end of the mounting base, a mounting shell fixedly connected to the upper surface of the mounting base, a pressure cylinder fixedly mounted at the middle of the upper surface of the mounting shell, a telescopic end of the pressure cylinder passing through the mounting shell and extending to the inner side of the mounting shell, a cutting blade fixedly connected to the telescopic end of the pressure cylinder, a pressure plate provided on both sides of the cutting blade, and two sliding grooves provided on both sides of the mounting shell, corresponding to the pressure plates, with sliding blocks fixedly connected to both ends of the pressure plates, the sliding blocks slidably connected to the inner side of the sliding grooves, and a driving mechanism fixedly connected to one side of the mounting base, the driving mechanism being fixedly connected to the sliding blocks. The driving mechanism and the sliding blocks are designed to cooperate, allowing the driving mechanism to drive the sliding blocks to slide within the sliding grooves, thereby driving the pressure plates to gradually approach the conveyor belt, thus pressing the PCB film on the conveyor belt firmly, making the cutting more stable.

[0006] According to the aforementioned cutting device for PCB film production, the driving mechanism includes a connecting plate, a sliding rod, a driving column, a limiting plate, a driving slot, a fixing block, a lead screw, a fixing frame, and a setting slot. The connecting plate is disposed on one side of the mounting housing, and the connecting plate is fixedly connected to one end of the surface of the sliding block. By configuring the cooperation between the connecting plate and the sliding block, the connecting plate can drive the sliding block to move synchronously when it moves.

[0007] According to the cutting device for PCB film production, the sliding block is rectangular, the sliding rod is fixedly connected to the lower surface of the connecting plate, and the fixing frame is fixedly connected to the side of the mounting base near the connecting plate. By setting the sliding block to a rectangular shape, the sliding block is limited and rotation is prevented when it moves.

[0008] According to the cutting device for PCB film production, the upper end of the connecting plate is provided with a setting groove, and the lower end of the sliding rod is slidably connected to the inner side of the setting groove, with the lower end of the sliding rod extending to the inner side of the fixed frame. By setting the sliding rod and the setting groove to cooperate with each other, the sliding rod is limited, making its movement more stable.

[0009] According to the cutting device for PCB film production, the sliding rod is rectangular, and the contact surface between the sliding rod and the setting groove is smooth. By making the contact surface between the sliding rod and the setting groove smooth, friction is reduced, making the movement of the sliding rod more stable.

[0010] According to the cutting device for PCB film production, the drive plate is slidably connected to the inner side of the fixed frame, the drive groove is formed on the surface of the drive plate, the drive column is fixedly connected to the side of the sliding rod away from the mounting base, and the drive column is slidably connected to the inner side of the drive groove. By moving the drive plate, the drive column moves within the drive groove, thereby driving the sliding rod to move up and down.

[0011] According to the aforementioned cutting device for PCB film production, the limiting plate is fixedly connected to the end of the drive column away from the sliding rod, the fixing block is fixedly connected to the lower side of the drive plate, the lead screw is threadedly connected to the inner side of the fixing block, and both ends of the lead screw pass through the fixing block and are rotatably connected to both sides of the fixing frame. A motor is fixedly installed on the lower outer side of the fixing frame, and the output end of the motor passes through the fixing frame and is fixedly connected to one end of the lead screw. The lead screw drives the drive plate to move through the fixing block, and the threads on the surface of the lead screw simultaneously move the drive plate and lock it, reducing the problem of the drive plate moving on its own if the motor fails.

[0012] According to the cutting device for PCB film production, a limiting plate is fixedly connected to the end of the sliding block away from the connecting plate, and the limiting plate is in contact with the outer surface of the mounting shell. By setting the limiting plate and the mounting shell to cooperate with each other, the limiting plate limits the sliding block, making the movement of the sliding block more stable.

[0013] The beneficial effects of this utility model are as follows: By setting up the cooperation between the drive mechanism, the pressure plate and the sliding block, the drive mechanism drives the sliding block to slide inside the sliding groove, thereby driving the pressure plate to gradually move closer to the conveyor belt, and then the pressure plate presses the PCB film on the conveyor belt, reducing the problem of the PCB film being blown away or deviated by the wind, and making the cutting blade more stable when cutting the PCB film.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
