Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to an edge grinding device for the production and processing of copper-clad laminates for printed circuit boards. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), copper-clad laminates (CCLs) are the core substrate, and the quality of their edge processing directly affects the etching accuracy, lamination effect, and overall performance of the subsequent PCB. Therefore, precise and efficient edge polishing is one of the key steps in the production and processing of CCLs.

[0003] Traditional copper clad laminate (CCL) edge grinding equipment has many limitations in practical applications. For CCL materials of different thicknesses, it is often necessary to change to a suitable edge grinding device or make complex mechanical adjustments, resulting in poor versatility. This not only increases equipment investment costs but also reduces production changeover efficiency. During the feeding process of CCL materials, manual pushing or simple transmission mechanisms are often relied upon, which can easily lead to movement deviations, resulting in uneven edge grinding and difficulty in ensuring edge accuracy, thus affecting the quality of subsequent processing. When multiple sides of the CCL need to be ground, the orientation of the CCL material must be manually adjusted, which is not only cumbersome to operate and prone to introducing positioning errors due to manual intervention, but also time-consuming to change sides, which seriously restricts the overall processing efficiency.

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.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-5 A grinding device for processing copper-clad laminates for printed circuit boards includes a base 1 and a mounting plate 9. A first electric push rod 10 is mounted on the mounting plate 9, and the output end of the first electric push rod 10 is connected to the base 1. A through groove is formed on the base 1, and a first support plate 11 is slidably connected in the through groove. The first support plate 11 is connected to the mounting plate 9 by multiple bolts. A second motor 12 is mounted on the first support plate 11, and the output end of the second motor 12 passes through the first support plate 11 and is connected to a first transmission wheel 13. A certain feature is formed on the first support plate 11. A first slide groove contains a first slider 14, which has a threaded hole. A second screw 15 is threaded into the threaded hole. The bottom end of the second screw 15 is rotatably connected to the first slide groove, and the top end of the second screw 15 passes through a first support plate 11 and is connected to a knob 16. A second drive wheel 17 is rotatably connected to the first slider 14. A grinding belt 18 is fitted onto the first drive wheel 13 and the second drive wheel 17, allowing the first electric push rod 10 to drive the grinding belt 18 through the mounting plate 9 to adjust its height to accommodate different thicknesses. The copper-clad laminate material is simultaneously driven by a second motor 12 to rotate the first transmission wheel 13, so that the first transmission wheel 13 and the second transmission wheel 17 cooperate to drive the grinding belt 18 to grind the burrs on the copper-clad laminate material. A knob 16 drives a second screw 15 to rotate, so that the second screw 15 drives the second transmission wheel 17 to move via a first slider 14, thereby adjusting the tension of the grinding belt 18. A second support plate 26 is slidably fitted on the base 1, and the second support plate 26 is connected to the mounting plate 9 by multiple bolts. A drive wheel 13 is rotatably engaged with a second support plate 26. A second groove is provided on the second support plate 26, and a second slider 27 is slidably connected in the second groove. The second slider 27 is rotatably engaged with the second drive wheel 17. A limit block 28 is bolted to the second slider 27. The second support plate 26 is connected to the mounting plate 9, which enhances the stability of the installation of the first drive wheel 13 and the second drive wheel 17. The setting of the second slider 27 and the limit block 28 further assists in fixing and adjusting the position of the second drive wheel 17, ensuring that the grinding belt 18 runs smoothly.

[0029] It should be noted that the base 1 has a strip groove, and a connecting post 3 is set in the strip groove. The connecting post 3 is rotatably connected to the disc 2. The bottom end of the connecting post 3 is fixedly connected to a limit plate 4. The bottom end of the limit plate 4 is fixedly connected to an adjusting plate 5. The bottom end of the base 1 is fixedly connected to two fixing plates 6. A first motor 7 is installed on the fixing plate 6. The output end of the first motor 7 passes through the fixing plate 6 and is connected to a first screw 8. The other end of the first screw 8 passes through the adjusting plate 5 and is rotatably connected to another fixing plate 6. The first screw 8 and the adjusting plate 5 are threaded together. The first motor 7 drives the adjusting plate 5 to move through the first screw 8, thereby driving the copper-clad laminate material on the disc 2 to move and control the copper-clad laminate material to move towards the grinding belt 18 for grinding. The adjusting plate 5 has two guide holes, and a guide rod 30 is slidably connected in the guide holes. The two ends of the guide rod 30 are fixedly connected to the two fixing plates 6. The guide rod 30 cooperates with the guide holes to provide guidance for the movement of the adjusting plate 5, ensuring the stability and accuracy of the movement of the adjusting plate 5.

[0030] It should also be noted that the support frame 19 is fixedly connected to the limiting plate 4, and a top plate 20 is fixedly connected to the top of the support frame 19. A second electric push rod 21 is installed on the top plate 20. The output end of the second electric push rod 21 is connected to a pressure block 22, and a rotating block 23 is rotatably connected to the bottom end of the pressure block 22. This causes the second electric push rod 21 to drive the pressure block 22 to move, so that the rotating block 23 and the disc 2 cooperate to clamp and fix the copper-clad laminate material. A third motor 24 is installed at the top of the pressure block 22, and a gear 25 is connected to the output end of the third motor 24 through the pressure block 22. The rotating block 23 has multiple toothed grooves that mesh with the gear 25, so that the third motor 24 drives the rotating block 23 to rotate through the engagement of the gear 25 and the toothed grooves, so as to cooperate with the disc 2 to drive the copper-clad laminate material to rotate. The top plate 20 has multiple anti-rotation holes, and an anti-rotation rod 29 is slidably connected in the anti-rotation hole. The anti-rotation rod 29 is fixedly connected to the pressure block 22. The anti-rotation rod 29 slides in the anti-rotation hole, which can prevent the pressure block 22 from rotating when it extends and retracts with the second electric push rod 21, ensuring that the pressing direction of the pressure block 22 and the rotating block 23 on the copper-clad laminate material is stable and improving the fixing effect.

[0031] In summary, the working principle and process of the edge grinding device for copper-clad laminate production and processing of printed circuit boards are as follows: First, the copper-clad laminate to be processed is placed on the disc 2. Then, the second electric push rod 21 is activated, causing the pressure block 22 to move downwards, gradually bringing the rotating block 23 closer to the copper-clad laminate until the rotating block 23 cooperates with the disc 2 to firmly clamp and fix the copper-clad laminate. Then, according to the thickness of the copper-clad laminate, the first electric push rod 10 is activated. The first electric push rod 10, through the mounting plate 9, drives the grinding belt 18 to adjust its height, aligning the grinding belt 18 with the edge height position of the copper-clad laminate to be ground. If the tension of the grinding belt 18 is not appropriate, the knob 16 is rotated, causing the second screw 15 to rotate, which in turn causes the first slider 14 to move the second transmission wheel 17 up and down, thereby adjusting the tension of the grinding belt 18. Then, the second... Motor 12 drives the first transmission wheel 13 to rotate, and the cooperation of the first transmission wheel 13 and the second transmission wheel 17 drives the grinding belt 18 to drive. Then, the first motor 7 is started, and the first motor 7 drives the adjusting plate 5 to move through the first screw 8, so as to drive the copper-clad laminate material on the disc 2 to move, so as to control the copper-clad laminate material to move towards the grinding belt 18 for grinding. When one edge of the copper-clad laminate material is ground, the first motor 7 drives the copper-clad laminate material to reset. Then, the third motor 24 is started. The third motor 24 drives the rotating block 23 to rotate through the cooperation of the gear 25 and the rotating block 23. The rotating block 23 drives the clamped copper-clad laminate material to rotate synchronously, rotating the next edge of the copper-clad laminate material to be ground to the position corresponding to the grinding belt 18. Then, the third motor 24 is turned off, and the first motor 7 is started again. The steps are repeated to grind the next edge of the copper-clad laminate material.

[0032] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
