[0002] To meet the ever-increasing functional demands of electronic products, circuit boards, as core components of electronic products, have become increasingly complex in design and manufacturing. This has led to the development of multi-panel PCB (printed circuit board) designs, which integrate multiple circuit boards onto a single large board and then separate them into individual boards through subsequent depaneling processes. V-grooves can guide the subsequent manual breaking process, making it smoother and more accurate, reducing damage to the circuit board. While some circuit board V-groove cutting devices exist on the market, these devices still have limitations in performance and functionality. Some cutting devices have fixed cutting blade positions, making it impossible to adjust them for different sizes and specifications of circuit boards, resulting in poor cutting versatility. When facing V-groove cutting requirements of different widths and spacings, frequent changes of cutting devices or complex adjustments are necessary, increasing production costs and time.

[0003] The existing device cannot adjust the cutting angle and depth during use. When cutting different materials, the blade needs to be changed frequently, which affects the processing efficiency. Therefore, we need to propose a circuit board V-groove cutting device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution:

[0022] A circuit board V-groove cutting device includes: a conveyor belt 1, a mounting frame 2 fixedly connected to the outer side of the conveyor belt 1, an electric push rod 3 fixedly connected inside the mounting frame 2, a lifting frame 4 fixedly connected to the output end of the electric push rod 3, a bidirectional lead screw 5 rotatably connected inside the lifting frame 4, a first motor 6 fixedly connected to one end of the bidirectional lead screw 5 through the lifting frame 4, two symmetrically distributed moving frames 7 threadedly connected to the outer side of the bidirectional lead screw 5, the lifting frame 4 slidably connected to the two moving frames 7 respectively, a rotating plate 8 rotatably connected inside each of the two moving frames 7, a second motor 9 fixedly connected to the rotating shaft of the rotating plate 8 through the moving frame 7, the lifting frame 4 fixedly connected to the first motor 6 and the second motor 9 respectively, a cutting blade 10 rotatably connected inside the rotating plate 8, and a third motor 11 fixedly connected to the rotating shaft of the cutting blade 10 through the rotating plate 8.

[0023] Through the cooperation of conveyor belt 1 and mounting frame 2, the technical effect of cutting V-grooves of different shapes on circuit boards is realized, which solves the technical problem that the device is not convenient for processing V-grooves of different shapes. Conveyor belt 1 is the key component in the whole device for transporting circuit boards. It operates continuously, transporting the circuit boards to be cut from one station to the cutting station, ensuring the continuity of the production process. The material and strength of conveyor belt 1 are carefully designed to withstand the weight of the circuit boards and the friction generated during transportation, ensuring stable operation for a long time.

[0024] A mounting frame 2 is fixedly connected to the outside of the conveyor belt 1. The mounting frame 2 provides a stable support structure for the entire cutting device. It not only supports important components such as the electric push rod 3, but also ensures the stability and accuracy of these components during operation.

[0025] The mounting bracket 2 is made of high-strength material and is precisely processed and installed to ensure that its connection with the conveyor belt 1 is firm and reliable. The electric push rod 3 is the power source for the lifting and lowering movement of the cutting blade 10. By controlling the extension and retraction of the electric push rod 3, the height of the cutting blade 10 can be precisely adjusted to meet the cutting needs of circuit boards of different thicknesses.

[0026] The lifting frame 4 serves as the mounting base for the cutting actuator. It is fixedly connected to the electric push rod 3 and moves up and down under the action of the electric push rod 3. When the first motor 6 starts, it drives the bidirectional lead screw 5 to rotate. Due to the special thread design of the bidirectional lead screw 5, the two moving frames 7 can move in opposite directions at the same time, thereby adjusting the distance between the two cutting blades 10 to adapt to the cutting requirements of V-grooves of different widths.

[0027] The lifting frame 4 is fixedly connected to the first motor 6 and the second motor 9 respectively, and is also slidably connected to the two moving frames 7 respectively. This connection method ensures that the moving frames 7 can move smoothly and accurately under the drive of the bidirectional lead screw 5. The second motor 9 can drive the rotating plate 8 to rotate, thereby adjusting the cutting angle of the cutting blade 10 to achieve the cutting of V-grooves at different angles.

[0028] The third motor 11 is the power source for the rotation of the cutting blade 10. It drives the cutting blade 10 to rotate at high speed to cut the circuit board. The cutting blade 10 is made of high-hardness and high-wear-resistant material, which can ensure the sharpness and precision of the cut and extend its service life. The two third motors 11 rotate in the same direction. The recommended model of the electric push rod 3 is Linak LA36-CB, the recommended model of the first motor 6 is Panasonic MINAS A6 series (MHMF042L1 U2M), the recommended model of the second motor 9 is Yaskawa SGM7G-1EA6C, and the recommended model of the third motor 11 is Kollmorgen AKM52E-ACCN2-00.

[0029] Multiple rubber plates 12 are evenly distributed and fixedly connected to the outer side of the conveyor belt 1. Through the cooperation of the conveyor belt 1 and the rubber plate 12 structure, the rubber plate 12 is fixed to the outer side of the conveyor belt 1. Due to the elasticity of the rubber plate 12, it is easy to fix the rubber plate 12 to the outer side of the conveyor belt 1, which in turn facilitates the fixing of the support plate 13. This solves the technical problem that the support plate 13 is inconvenient to install during the rotation of the conveyor belt 1.

[0030] Support plates 13 are fixedly connected to the outer sides of multiple rubber plates 12, and the support plates 13 are in contact with the conveyor belt 1. Through the cooperation of the rubber plates 12 and the support plates 13, the support plates 13 provide a stable support platform for the circuit board. It can bear the weight of the circuit board and maintain the flatness of the circuit board during transportation. The surface of the support plates 13 is specially treated to be smooth and flat, which will not scratch the circuit board. This solves the technical problem that the circuit board is not easy to place.

[0031] The interior of the multiple support plates 13 is provided with two symmetrically distributed sliding grooves 14. The interior of each sliding groove 14 is slidably connected to a slider 15. The upper end of each slider 15 is fixedly connected to a screw 16. The screw 16 is slidably connected to the multiple sliding grooves 14 respectively.

[0032] Through the cooperation of the slide groove 14, slider 15 and screw 16 structure, multiple screws 16 are slidably connected to multiple slide grooves 14 respectively. The design of slide groove 14 and slider 15 enables the screw 16 to move horizontally on the support plate 13, thereby adjusting the position of the pressure plate 17 to meet the positioning requirements of circuit boards of different sizes. This solves the technical problem that the device is not convenient for installing circuit boards of different shapes.

[0033] Multiple screws 16 have pressure plates 17 on their outer sides, and multiple pressure plates 17 are in contact with multiple support plates 13 respectively. Multiple screws 16 have fixing nuts 18 threadedly connected to their outer sides, and multiple fixing nuts 18 are in contact with multiple pressure plates 17 respectively.

[0034] By cooperating with the screw 16, pressure plate 17, and fixing nut 18, the position of the pressure plate 17 can be adjusted by moving the screw 16 after the circuit board is placed on the support plate 13, so that it presses against the circuit board. Then, the fixing nut 18 is tightened to fix the pressure plate 17, thereby achieving a firm positioning of the circuit board, preventing the circuit board from moving during the cutting process, ensuring the cutting accuracy, and solving the technical problem of instability of the circuit board during cutting.

[0035] Working principle: When using this utility model, loosen the fixing nut 18 to release the limit on the pressure plate 17 and the slider 15, move the slider 15 by the screw 16 to facilitate the fixing of circuit boards of different widths, tighten the fixing nut 18 to fix the pressure plate 17, the pressure plate 17 presses on the upper end of the circuit board to fix the circuit board, and the conveyor belt 1 drives the support plate 13 and the circuit board to move.

[0036] The electric push rod 3 drives the lifting frame 4 to rise and fall. The second motor 9 adjusts the angle of the rotating plate 8, which in turn adjusts the angle of the cutting blade 10. The first motor 6 drives the bidirectional lead screw 5 to rotate. The bidirectional lead screw 5 and the moving frame 7 undergo threaded movement, controlling the moving frame 7 to move and adjusting the distance between the cutting blades 10 after the angle is adjusted. The third motor 11 drives the cutting blade 10 to rotate, and the cutting blade 10 cuts V-grooves on the circuit board.

[0037] In this application, the electric push rod 3, the first motor 6, the second motor 9, and the third motor 11 are controlled automatically by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
