Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board cutting technology, and in particular to a dimensional cutting device for circuit board processing. Background Technology
[0002] Circuit boards, also known as printed circuit boards, are made of copper or plastic. The main advantages of using circuit boards are significantly reduced wiring and assembly errors, improved automation levels, and higher labor productivity. During circuit board production, cutting is necessary. Cutting divides large circuit board substrates into smaller pieces to ensure each board conforms to design specifications, facilitating standardized production. Simultaneously, cut circuit boards are easier to handle and transport, improving production efficiency. Existing circuit board cutting equipment typically places the circuit board on a worktable, where a high-speed rotating cutting tool cuts it. During this process, the circuit board is subjected to pressure and friction from the cutting tool, causing it to wobble or tilt, resulting in positional shifts that significantly affect cutting accuracy and reduce dimensional uniformity in mass production. Therefore, a dimensional cutting device for circuit board processing is proposed. Utility Model Content

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] Example 1:
[0033] Reference Figures 1 to 3This utility model provides a circuit board processing dimensional cutting device, including a worktable 10, a cutting assembly 20, and a fixing assembly 30. The worktable 10 is provided with a positioning plate 11 and a support frame 12. The positioning plate 11 is used for positioning the circuit board; that is, when the circuit board to be cut is placed on the worktable 10, one side (or both sides) of the circuit board abuts against the side of the positioning plate 11, and the circuit board is cut to the required size. The cutting assembly 20 includes a telescopic cylinder 21 mounted on the support frame 12, a drive motor mounted on the telescopic end of the telescopic cylinder 21, and a cutter 22 mounted on the output shaft of the drive motor. The support frame 12 has a vertical plate on the worktable 10 and a horizontal support plate mounted on the vertical plate. The telescopic cylinder 21 is mounted on the horizontal support plate. The horizontal support plate has a fourth through hole through which the output shaft of the telescopic cylinder 21 passes. When the telescopic cylinder 21 is working, it drives the drive motor to move up and down, thereby moving the cutter 22 up and down; the drive motor drives the cutter 22 to rotate, thereby cutting the circuit board. A fixing component 30 is positioned between the worktable 10 and the drive motor. The fixing component 30 includes a hollow telescopic rod 31, within which a compression spring 32 is installed. A pressure plate 33 is located at the end of the telescopic rod 31 closest to the worktable 10. It should be noted that the compression spring 32 is always compressed; that is, the telescopic rod 31 is at its longest length when not subjected to external pressure. Furthermore, when the telescopic cylinder 21 is in the retracted state, the distance between the pressure plate 33 and the worktable 10 is less than the distance between the cutter 22 and the worktable 10. Therefore, during the downward movement of the drive motor and cutter 22 driven by the telescopic cylinder 21, the pressure plate 33 first contacts the circuit board. That is, before the cutter 22 cuts the circuit board, the drive motor moves the telescopic rod 31 and the pressure plate 33 downwards and presses down to fix the circuit board. This ensures that the circuit board is fixed during cutting, preventing it from shaking or tilting, and thus preventing positional displacement during the cutting process. This effectively improves the cutting accuracy of the circuit board and enhances the dimensional uniformity of circuit boards in mass production.
[0034] Furthermore, the positioning plate 11 is provided with mounting holes, and the worktable 10 is provided with multiple threaded holes corresponding to the mounting holes. That is, the positioning plate 11 and the worktable 10 are connected by bolts, which facilitates the operator to adjust the position of the positioning plate 11, thereby adjusting the size of the cut circuit board. The worktable 10 is provided with cutting holes, and the cutting tool 22 can be embedded into the cutting holes when cutting the circuit board. The bottom surface of the worktable 10 is provided with support columns 14.
[0035] Optionally, a motor housing 25 is fixedly installed at the telescopic end of the telescopic cylinder 21. The drive motor is installed inside the motor housing 25, and the output shaft of the drive motor passes through the housing wall of the motor housing 25 and extends to the outside of the motor housing 25. The fixing component 30 of this embodiment is fixed to the bottom surface of the motor housing 25. Specifically, the fixing component 30 also includes a base plate 34 disposed on the bottom surface of the motor housing 25, and the base plate 34 is bolted to the motor housing 25. The end of the telescopic rod 31 away from the pressure plate 33 is fixedly connected to the base plate 34, that is, one end of the compression spring 32 is connected to the pressure plate 33, and the other end is connected to the base plate 34. Since the compression spring 32 is always in a compressed state, when the compression spring 32 applies pressure to the circuit board through the pressure plate 33, it can generate greater pressure, thereby fixing the circuit board. Moreover, during the process of the cutter 22 cutting the circuit board, the force applied by the pressure plate 33 to the circuit board is always the spring force, thereby avoiding excessive pressure and damage to the circuit board.
[0036] This utility model discloses a dimensional cutting device for circuit board processing. The specific implementation is as follows: When cutting a circuit board, the circuit board is placed on a worktable 10 and abutted against a positioning plate 11, thereby positioning the circuit board according to the required dimensions. A telescopic cylinder 21 and a drive motor are activated. The telescopic cylinder 21 drives the drive motor to move towards the worktable 10, and the drive motor drives the cutter 22 and the telescopic rod 31 to move towards the circuit board. Since the fixing component 30 is fixed to the bottom surface of the motor housing 25, the motor housing 25 synchronously drives the cutter 22, the telescopic rod 31, and the pressure plate 33 to move downwards. The pressure plate 33 first contacts and fixes the circuit board. When the cutter 22 contacts and cuts the circuit board, the circuit board is fixed, thus preventing it from shaking or tilting.
[0037] Example 2:
[0038] Reference Figures 4 to 6This utility model provides a dimensional cutting device for circuit board processing. The difference between this embodiment and Embodiment 1 lies in the fixing component 30. Specifically, a first horizontal plate 13 is provided on the support frame 12, and the first horizontal plate 13 has a first through hole. The fixing component 30 also includes a base plate 35 disposed on the first horizontal plate 13, and the base plate 35 is bolted to the first horizontal plate 13. The base plate 35 has a second through hole, and the axis of the first through hole and the axis of the second through hole are on the same straight line. A telescopic rod 31 passes through the first through hole and the second through hole. A movable plate 36 is provided at the end of the telescopic rod 31 away from the pressure plate 33, that is, one end of the compression spring 32 is connected to the pressure plate 33, and the other end is connected to the movable plate 36. A return spring 37 is provided between the base plate 35 and the movable plate 36. In the initial state, the return spring 37 causes the movable plate 36 to move away from the base plate 35, thereby preventing the pressure plate 33 from contacting the worktable 10, so that the operator can place the circuit board to be cut on the worktable 10. A second horizontal plate 38 is provided on the bottom surface of the motor housing 25, and the first horizontal plate 13 is parallel to the second horizontal plate 38. When the telescopic cylinder 21 drives the drive motor to move downward, the drive motor drives the second horizontal plate 38 and the cutter 22 to move downward. During the downward movement of the second horizontal plate 38 and the cutter 22 by the drive motor, the second horizontal plate 38 first contacts the moving plate 36 and presses down on the moving plate 36. At this time, the return spring 37 is compressed, the telescopic rod 31 and the pressure plate 33 move downward, and before the cutter 22 contacts the circuit board, the pressure plate 33 contacts the circuit board first and applies pressure to the circuit board, thereby fixing the circuit board.
[0039] Furthermore, a mounting plate 23 is fixedly installed at the telescopic end of the telescopic cylinder 21, and a linear motor 24 is installed on the bottom surface of the mounting plate 23. The motor housing 25 is installed on the linear motor 24. When the circuit board is large, the linear motor 24 drives the cutter 22 to move along the cutting line of the circuit board through the drive motor, thereby cutting the circuit board.
[0040] In this embodiment, when the linear motor 24 drives the drive motor to move so that the cutter 22 moves along the cutting line of the circuit board, the moving plate 36 is always subjected to the pressure applied by the second horizontal plate 38, that is, the pressure plate 33 always applies pressure to the circuit board, so that the pressure plate 33 can still fix the circuit board during the process of the cutter 22 moving to cut the circuit board.
[0041] Furthermore, the support frame 12 has a third through hole 15 on its upright plate. When the linear motor 24 drives the drive motor to move, the second horizontal plate 38 can pass through the third through hole 15.
[0042] Furthermore, a roller 39 is provided on the movable plate 36. Specifically, the movable plate 36 has a fifth through hole, and a rotating shaft is provided on the side wall of the fifth through hole, with the roller 39 mounted on the rotating shaft. It should be noted that the roller 39 is rotatably connected to the movable plate 36 via the rotating shaft, and the rolling direction of the roller 39 is the same as the moving direction of the mover of the linear motor 24. When the second horizontal plate 38 exerts pressure on the movable plate 36, and the linear motor 24 drives the second horizontal plate 38 to move via the drive motor, the roller 39 rolls, that is, the second horizontal plate 38 applies pressure to the movable plate 36 through the roller 39 and the rotating shaft, thereby reducing the friction between the second horizontal plate 38 and the movable plate 36.
[0043] It should be noted that the circuit board processing size cutting device in Embodiment 1 is suitable for cutting small-sized circuit boards, that is, the linear motor 24 does not need to move, and the cutter 22 can complete the cutting of the circuit board. The circuit board processing size cutting device in Embodiment 2 is suitable for cutting large-sized circuit boards, that is, the linear motor 24 needs to drive the cutter 22 to move along the cutting line of the circuit board to complete the cutting of the circuit board.
[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
