Description

Technical Field

[0001] This utility model relates to the field of edge grinding technology, and in particular to an edge grinding device. Background Technology

[0002] Copper clad laminate (CCL) is a crucial basic material in the electronics manufacturing industry, widely used in the production of printed circuit boards (PCBs). During the CCL cutting process, due to the limitations of mechanical cutting, burrs or unevenness may appear on the edges of the cut CCL. These burrs and unevenness not only affect the accuracy of subsequent processing but may also lead to poor adhesion of printing ink or defects during etching. Edge grinding can effectively remove these burrs, making the edges smoother and thus improving the processing results of subsequent steps.

[0003] In existing technologies, traditional production lines use manual flipping or multiple robotic arms to change the edge of copper-clad laminates. This operation is time-consuming and requires interruption of continuous production, which severely restricts the overall processing efficiency. Therefore, we propose an edge grinding device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an edge grinding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An edge grinding device includes a corner frame and four frames. A rotating seat is placed inside the corner frame. Two transmission rollers are rotatably connected to the inner wall of the rotating seat. Two transmission belts are sleeved on the outer walls of the two transmission rollers. An electric motor is fixedly connected to the outer wall of the rotating seat. One end of the output shaft of the electric motor is fixedly connected to the outer wall of one of the transmission rollers. A microwave induction sensor is fixedly connected inside the rotating seat. Two brackets are fixedly connected inside the corner frame. The top of the two brackets is fixedly connected to the same support ring. A servo motor is fixedly connected inside the corner frame. The top of the output shaft of the servo motor is fixedly connected to the bottom of the rotating seat. An adjustment component is provided at the bottom of the corner frame.

[0007] Preferably, the adjustment component includes four threaded rods, the tops of which are fixedly connected to the bottom of the corner frame, and the bottoms of which are threaded with foot sleeves. By setting the adjustment component, the height of the transmission belt can be adjusted to meet the same horizontal height as the belt conveyor.

[0008] Preferably, each of the four frames is equipped with a belt conveyor and a belt sander. A copper-clad laminate is placed on top of one of the belt conveyors. When the belt conveyor transports the copper-clad laminate, one side of the copper-clad laminate comes into contact with the sanding belt on the belt sander. The operation of the belt sander polishes the copper-clad laminate through its own rotating sanding belt. The copper-clad laminate moves due to the friction between the belt on the belt conveyor and the copper-clad laminate.

[0009] Preferably, the outer wall of the rotating seat has a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the electric motor, so that the electric motor drives the transmission belt to rotate.

[0010] Preferably, a baffle is fixedly connected to the outer wall of the rotating seat to prevent the copper-clad laminate from deviating.

[0011] Preferably, the top of the support ring contacts the bottom of the rotating seat, and the support ring assists the rotating seat in stable rotation.

[0012] Preferably, an encoder is fixedly sleeved on the outer wall of the servo motor output shaft to detect the rotation angle of the servo motor output shaft.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution enables continuous automatic reversal of the board material, completing four-sided grinding without manual intervention, which greatly improves production efficiency. By using corner frames set between the four frames, the copper-clad board is reversed, completing the four-sided cyclic grinding process, reducing the intensity of manual operation and improving production efficiency.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, an edge grinding device is disclosed, comprising a corner frame 5 and four frames 1. Each of the four frames 1 is equipped with a belt conveyor 2. The belt conveyor 2 uses a non-slip and wear-resistant belt, and the surface can be coated with rubber stripes or silicone to enhance the stability of the sheet material during conveying and prevent slippage and deviation. Each of the four frames 1 is equipped with a belt sander 3. The belt sander 3 is equipped with an automatic tensioning mechanism to prevent the sander belt from loosening and affecting the grinding accuracy. A copper-clad board 4 is placed on top of one of the belt conveyors 2, and a rotating seat 6 is placed inside the corner frame 5.

[0023] An existing pneumatic clamping device or vacuum suction hole can be added to the top of the belt conveyor 2 to fix the plate during processing and prevent displacement caused by the grinding force of the sander 3.

[0024] Two drive rollers 7 are rotatably connected to the inner wall of the rotary seat 6. Two drive belts 9 are sleeved on the outer wall of the two drive rollers 7. The drive belts 9 are made of a high friction coefficient material such as polyurethane synchronous belt to ensure that they do not slip on the contact surface with the board. An electric motor 8 is fixedly connected to the outer wall of the rotary seat 6. A circular hole is opened on the outer wall of the rotary seat 6. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the electric motor 8. One end of the output shaft of the electric motor 8 is fixedly connected to the outer wall of one of the drive rollers 7. A microwave induction sensor 10 (WTL580) is fixedly connected inside the rotary seat 6. The microwave induction sensor 10 (WTL580) is used to detect the position and rotation angle of the board. The signal is fed back to the existing PLC controller to control the rotation angle of the servo motor 14 to realize the corner grinding.

[0025] A baffle 11 is fixedly connected to the outer wall of the rotating base 6. Two brackets 13 are fixedly connected to the inside of the corner frame 5. The top of the two brackets 13 is fixedly connected to the same support ring 12. The top of the support ring 12 is in contact with the bottom of the rotating base 6. A servo motor 14 is fixedly connected to the inside of the corner frame 5. An encoder 15 (e100h) is fixedly sleeved on the outer wall of the output shaft of the servo motor 14. The encoder 15 (e100h) determines the rotation angle by detecting the physical change in rotation on the output shaft of the servo motor 14. The top of the output shaft of the servo motor 14 is fixedly connected to the bottom of the rotating base 6.

[0026] The bottom of the corner frame 5 is provided with an adjustment component, which includes four threaded rods 16. The top of each of the four threaded rods 16 is fixedly connected to the bottom of the corner frame 5, and the bottom of each of the four threaded rods 16 is threaded with a foot sleeve 17.

[0027] Working principle: In use, additional corner frames 5 are added, located at the corners between the four frames 1. After the copper-clad laminate 4 is polished on one side, it is conveyed into the corner frame 5 by the belt conveyor 2. The microwave induction sensor 10 detects the position of the copper-clad laminate 4, and the operation of the electric motor 8 drives the connected transmission roller 7 to rotate, causing the transmission belt 9 to rotate, so that the copper-clad laminate 4 is positioned on top of the rotating seat 6. The baffle 11 prevents the copper-clad laminate 4 from moving out of position. The servo motor 14 drives the rotating seat 6 to rotate. The rotating seat 6 rotates, causing the copper-clad laminate 4 to rotate at a 90-degree angle. The encoder 15 detects the rotation angle of the output shaft of the servo motor 14, and the electric motor 8 rotates in the opposite direction to cause the transmission belt 9 to rotate in the opposite direction, conveying the copper-clad laminate 4 outward to another belt conveyor 2. By rotating and changing the side, the other side of the copper-clad laminate 4 is placed on the side of the sander 3, which performs the sanding process. The overall sanding process has a U-shaped structure. By changing the side at the four corners, it is convenient to perform four-sided sanding on the copper-clad laminate 4.

[0028] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the belt conveyor 2, belt sander 3, electric motor 8, microwave sensor 10, servo motor 14, and encoder 15 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that this hardware structure improvement can achieve, based on common knowledge.
