Description

Technical Field

[0001] This utility model relates to the field of stepper motor driver circuit board processing technology, and in particular to a side trimming and cutting device for processing stepper motor driver circuit boards. Background Technology

[0002] A circuit board, also known as a flexible circuit board, is a type of printed circuit board made of polyimide or polyester film as the substrate. It is highly reliable and extremely flexible, featuring high wiring density, light weight, thinness, and bendability. Circuit boards are classified into three main categories according to the number of layers: single-sided, double-sided, and multilayer circuit boards. Circuit boards are mainly composed of pads, vias, mounting holes, wires, components, connectors, fillers, and electrical boundaries. Drilling equipment is required during the processing of circuit boards.

[0003] In the production process of circuit boards, cutting equipment is needed to trim their sides. Conventional cutting equipment is often cumbersome to operate when positioning circuit boards of different sizes, and it is not convenient to adjust the position of the trimmed side of the circuit board to correspond with the cutting machine so that it can be cut quickly and accurately. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a side trimming and cutting device for processing stepper motor driver circuit boards, thereby solving the problems mentioned in the background art.

[0005] A side trimming and cutting device for processing a stepper motor driver circuit board includes a worktable and a positioning mechanism and a cutting mechanism mounted on the worktable. The positioning mechanism includes a fixed platform, an adjusting plate, a screw, a second motor, a bidirectional lead screw, a connecting part, and a limiting part. The fixed platform is vertically mounted on the upper plate of the worktable. The adjusting plate slides along a short slot in the fixed platform. The screw is positioned opposite the upper and lower end faces of the fixed platform and passes through the upper and lower ends of the adjusting plate, respectively. The adjusting plate's freedom of movement to one side can be limited by a nut on the screw. The second motor is fixed to the bottom surface of the fixed platform. The bidirectional lead screw is fixedly mounted at the output end of the second motor. There are two sets of limiting parts, each set consisting of two opposing sliding parts in a long groove on the fixed platform. The two adjacent limiting parts are connected to the bidirectional lead screw through the connecting part.

[0006] By adopting the above technical solution, it is convenient to position circuit boards of different sizes, and accurate adjustments can be made according to the length of the side trimming of the circuit board before trimming.

[0007] The cutting mechanism is mounted on the workbench via a bracket and includes a motor, a lead screw, a slide block, and a cutting machine. The lead screw is fixedly mounted at the output end of the motor. The slide block is connected to the lead screw and slides along the bracket. The cutting machine is fixedly mounted on the slide block.

[0008] The circuit board is cut by adopting the above technical solution.

[0009] The workbench has a collection trough in the middle of its base plate, and baffles are installed on both sides of the base plate.

[0010] By adopting the above technical solution, debris can be collected.

[0011] A measuring ruler is also installed on the upper surface of the fixed platform.

[0012] By adopting the above technical solution, it is possible to locate the circuit board according to the length of the trimmed edge and with reference to a measuring ruler.

[0013] The limiting part has a trapezoidal opening in the middle, and a rubber pad is installed at the opening of the limiting part.

[0014] By adopting the above technical solution, it is possible to clamp circuit boards of different thicknesses, and the rubber pad can avoid damage to the circuit boards by hard clamping.

[0015] The advantages of this utility model of a side trimming and cutting device for processing stepper motor driver circuit boards are:

[0016] 1. Place the circuit board inside the fixed platform. Referring to the measuring ruler, align the cutting position of the circuit board edge with the cutting blade position of the cutting machine. Push the adjusting plate to move so that the side of the adjusting plate fits against the side of the circuit board. Turn the nut on the screw to restrict the degree of freedom of the adjusting plate in the direction away from the circuit board. Then drive motor 2 to drive the two sets of connecting parts to move relative to each other through the double-acting screw. The connecting parts can be clamped and limited on both sides of the circuit board through the limiting part. Then drive motor 1 to drive the slide to move along the bracket through the screw. The slide then drives the cutting machine to cut and trim the side of the circuit board. This makes it easy to position circuit boards of different sizes. And according to the length of the trimmed side of the circuit board, it can be accurately adjusted before trimming.

[0017] 2. A collection groove is provided in the middle of the bottom plate of the workbench, and baffles are also installed on both sides of the bottom plate of the workbench. The baffles on both sides of the workbench serve to protect the workbench and prevent the debris generated by the cutting machine from splashing everywhere when cutting the circuit board. The groove at the bottom of the workbench can be used to collect the debris. Attached Figure Description

The connecting parts 14 can limit and clamp the two sides of the circuit board through the limiting part 15. Then, the first drive motor 4 drives the slide 6 to move along the bracket 3 through the lead screw 5. The slide 6 drives the cutting machine 7 to cut and repair the side of the circuit board.

[0026] A collection groove is provided in the middle of the bottom plate of the workbench 1. Baffles 2 are also installed on both sides of the bottom plate of the workbench 1. The baffles 2 on both sides of the workbench 1 can serve as a protective measure and can also prevent the debris generated by the cutting machine 7 from splashing everywhere when cutting the circuit board. A groove is provided at the bottom of the workbench 1 for collecting debris.

[0027] The cutting mechanism is mounted on the workbench 1 via the bracket 3, and includes a motor 4, a lead screw 5, a slide 6, and a cutting machine 7.
