Description

Technical Field

[0001] This utility model relates to the field of electronic circuit manufacturing technology, and in particular to a thick copper circuit edge grinding device. Background Technology

[0002] In the field of electronic circuit manufacturing, thick copper circuit boards are widely used in industries with high requirements for current transmission, such as power supplies and automotive electronics, due to their excellent current carrying capacity and mechanical strength. Grinding the edges of the circuit boards is a key process to ensure their dimensional accuracy and surface quality, directly affecting subsequent assembly and electrical performance.

[0003] Currently, most existing thick copper circuit board edge grinding equipment on the market uses a fixed-gap grinding wheel structure or only has a single manual adjustment function. Such equipment struggles to achieve rapid and precise adaptive adjustments when dealing with circuit boards of different batches, thicknesses, and sizes. On one hand, fixed-gap grinding wheels cannot meet the processing needs of diverse products, leading to over- or under-grinding of some circuit boards due to inappropriate wheel spacing, affecting product yield. On the other hand, manual adjustment is not only inefficient but also lacks precision, failing to meet the processing requirements of high-precision circuit boards.

[0004] Therefore, there is an urgent need to develop an edge grinding device that can flexibly adjust the spacing of the grinding wheels to adapt to circuit boards of different specifications. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this utility model provides a thick copper circuit edge grinding device.

[0006] The technical solution of this utility model is as follows: a thick copper circuit edge grinding device, comprising a base, a support frame, a conveyor wheel, a first motor, a grinding wheel, a baffle, a lifting frame, a connecting wheel, a lifting component, and an adjusting component. The top of the base is symmetrically connected to the support frame, and multiple conveyor wheels are rotatably connected between the two support frames at intervals. The left side of each support frame is slidably connected to the first motor via a slider. A grinding wheel is connected to the output shaft of each first motor, and the two grinding wheels are located on the front and rear sides of the conveyor wheel, respectively. A baffle is connected to the top of each support frame, and the two baffles are arranged opposite each other. A lifting frame is slidably connected between the two baffles. Multiple connecting wheels are rotatably connected to the bottom of the lifting frame. A lifting component is provided on the baffle, and an adjusting component is provided on the support frame.

[0007] As a preferred option, the grinding wheel is made of a high-hardness abrasive material.

[0008] Preferably, the connecting wheel is made of elastic rubber material.

[0009] Preferably, the lifting assembly includes a second motor and a screw. The second motor is installed between the tops of the two baffles, and the screw is connected to the output shaft of the second motor. The screw is threadedly connected to the lifting frame.

[0010] Preferably, the adjustment assembly includes an electric push rod, a first piston rod, a cylinder, and a second piston rod. An electric push rod is installed between the bottom right sides of the two support frames. The first piston rod is connected to the telescopic rod of the electric push rod. A cylinder containing liquid is connected between the bottom left sides of the two support frames. The cylinder has a T-shaped structure. The second piston rod is slidably connected to the front and rear sides of the cylinder. The outer ends of the second piston rod are connected to the slider on the first motor. The first piston rod is slidably connected to the right side of the cylinder.

[0011] Preferably, the device also includes a frame, a dustproof net, and a connecting pipe. The left side of the slider on the first motor is equipped with a frame, the outside of the frame is connected to and communicates with a connecting pipe, and the inside of the frame is connected to a dustproof net.

[0012] Beneficial effects: 1. The adjustment component adopts an electric push rod and a hydraulic transmission mechanism, which can precisely control the distance between the two grinding wheels; the lifting component is driven by a second motor and a screw, which can flexibly adjust the height of the connecting wheel, so that the equipment can be adapted to circuit boards of different thicknesses and sizes, significantly enhancing the versatility of the equipment.

[0013] 2.

At the same time, the dustproof net prevents debris from clogging the air passage, extending the service life of the equipment and reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example: A thick copper circuit edge grinding device, such as Figures 1-4 As shown, the circuit board includes a base 1, a support frame 2, conveyor wheels 3, a first motor 8, a grinding wheel 9, a baffle 10, a lifting frame 13, a connecting wheel 14, a lifting assembly, and an adjusting assembly. The support frames 2 are symmetrically connected to the top of the base 1, and multiple conveyor wheels 3 are rotatably connected between the two support frames 2 for conveying the circuit board. The first motor 8 is slidably connected to the left side of each support frame 2 via a slider. Grinding wheels 9 are connected to the output shaft of each first motor 8. The two grinding wheels 9 are located on the front and rear sides of the conveyor wheels 3, respectively, for grinding the edges of the circuit board. The grinding wheels 9 are made of a high-hardness abrasive material, such as silicon carbide. Silicon carbide abrasive has… With its high hardness and sharpness, it is suitable for grinding materials with high hardness, such as thick copper circuit boards. The top of the support frame 2 is connected to a baffle 10, and the two baffles 10 are set opposite each other. A lifting frame 13 is slidably connected between the two baffles 10. Multiple connecting wheels 14 are rotatably connected to the bottom of the lifting frame 13. The connecting wheels 14 are made of elastic rubber material, which can not only provide sufficient friction to ensure the limiting and auxiliary movement of the circuit board, but also buffer the vibration generated by the circuit board during movement to a certain extent, protecting the surface of the circuit board from damage. The baffle 10 is equipped with a lifting component, and the support frame 2 is equipped with an adjustment component.

[0021] like Figure 1 and Figure 4 As shown, the lifting assembly includes a second motor 11 and a screw 12. The second motor 11 is bolted between the tops of the two baffles 10. The screw 12 is connected to the output shaft of the second motor 11. The screw 12 is threadedly connected to the lifting frame 13. The second motor 11 drives the screw 12 to rotate, thereby realizing the up and down movement of the lifting frame 13.

[0022] like Figure 3 As shown, the adjustment assembly includes an electric push rod 4, a first piston rod 5, a cylinder 6, and a second piston rod 7. The electric push rod 4 is bolted between the bottom right sides of the two support frames 2. The first piston rod 5 is connected to the telescopic rod of the electric push rod 4. The cylinder 6, which contains liquid, is connected between the bottom left sides of the two support frames 2. The cylinder 6 has a T-shaped structure. The second piston rod 7 is slidably connected to the front and rear sides of the cylinder 6. The outer ends of the second piston rod 7 are connected to the slider on the first motor 8. The first piston rod 5 is slidably connected to the right side of the inside of the cylinder 6. The electric push rod 4 drives the first piston rod 5 to move, and the liquid pressure pushes the second piston rod 7 to adjust the spacing of the grinding wheels 9.

[0023] When performing edge grinding on thick copper circuit boards, the circuit boards are sequentially conveyed onto the conveyor wheel 3 by the conveyor equipment. The conveyor wheel 3 assists the circuit board to move to the left by its own rotation. The first motor 8 is started, and its output shaft drives the grinding wheel 9 to rotate at high speed. After the circuit board moves to the left and enters the grinding area, the two sides of the circuit board contact the grinding wheel 9, and the top surface contacts the connecting wheel 14. The connecting wheel 14 rotates under the action of friction with the circuit board, which not only limits the circuit board but also assists the circuit board to move stably. As the circuit board continues to move, the abrasive grains on the surface of the grinding wheel 9 rub against the edge of the circuit board, thereby removing excess copper material from the edge of the circuit board and achieving the purpose of edge trimming. The ground circuit board continues to move to the left for subsequent collection or transfer to the next process. Through this continuous conveying method, the orderly grinding of the circuit board can be achieved. To accommodate the thickness and size of different batches of circuit boards, this equipment can flexibly adjust the distance between the two grinding wheels 9 and the height of the connecting wheel 14. When the distance between the grinding wheels 9 needs to be adjusted, the electric push rod 4 is activated, controlling its extension rod to extend, driving the first piston rod 5 to move to the left. The first piston rod 5 pushes the liquid inside the cylinder 6, and the liquid pressure causes the second piston rods 7 on the front and rear sides to move outward, thereby driving the slider, the first motor 8, and the grinding wheels 9 to move synchronously, thus increasing the distance between the grinding wheels 9. Conversely, controlling the extension rod of the electric push rod 4 to shorten, the first piston rod 5 moves to the right to pump liquid, and under the action of internal pressure, the second piston rods 7 on the front and rear sides move inward, thus decreasing the distance between the grinding wheels 9. If the height of the connecting wheel 14 needs to be adjusted, the second motor 11 is activated, and its output shaft drives the screw 12 to rotate. Under the action of threaded transmission, the lifting frame 13 and the connecting wheel 14 move in the vertical direction. By controlling the forward and reverse rotation of the output shaft of the second motor 11, the lifting and lowering of the connecting wheel 14 can be precisely controlled. After the height adjustment is completed, the second motor 11 is turned off.

[0024] like Figure 2 As shown, the system also includes a frame 15, a dustproof net 16, and a connecting pipe 17. The left side of the slider on the first motor 8 is bolted to the frame 15. The outer side of the frame 15 is connected to and connected to the connecting pipe 17. The inner side of the frame 15 is connected to the dustproof net 16. During the operation of the equipment, when the circuit board is being ground, the external air pump is connected to the connecting pipe 17 through a quick connector. After the air pump is started, it uses airflow to suck the debris generated by the grinding wheel 9 during the grinding of the circuit board to both sides, so that the debris is quickly removed from the surface of the circuit board and the working area of ​​the grinding wheel 9. This effectively avoids the accumulation of debris on the grinding contact surface, thereby preventing the problem of reduced grinding accuracy caused by debris clogging. At the same time, the dustproof net 16 set on the inner side of the frame 15 can form a physical interception barrier. When the airflow carries the debris, it effectively prevents the debris from entering the interior of the connecting pipe 17, avoiding blockage of the connecting pipe 17 and failure of the air path, and ensuring the stable operation of the equipment's dustproof system.
