Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of insulating board surface polishing, and more specifically, to an insulating board surface polishing apparatus. Background Technology

[0002] In many fields such as electronics, aerospace, and electronics, insulating boards are widely used due to their excellent electrical insulation and mechanical properties. The quality of their surface polishing directly affects the electrical performance, appearance, and subsequent performance of the insulating board.

[0003] Currently, traditional insulating board surface polishing equipment has significant drawbacks in the processing. Existing polishing equipment typically processes insulating boards by feeding and clamping them one by one. Each time a board is fed, operators need to spend a significant amount of time and effort precisely positioning and complex clamping operations to ensure its stability during polishing. This cumbersome feeding process not only consumes a large amount of labor but also greatly reduces production efficiency, making it difficult to meet the needs of large-scale, batch production. In addition, frequent clamping operations can easily damage the surface of the insulating board, affecting product quality; furthermore, the complex clamping structure increases the equipment's maintenance costs and operational difficulty.

[0004] Therefore, developing a surface polishing device for insulating boards that can reduce the fixing and clamping process and improve the feeding efficiency has become an urgent need to improve the production efficiency and product quality of insulating board polishing and reduce production costs. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an insulating board surface polishing device, which solves the technical problem that existing polishing equipment in the prior art usually processes insulating boards by feeding and fixing them one by one. Each time the boards are fed, the operator needs to spend a lot of time and effort to accurately position and perform complex fixing and clamping operations.

[0006] According to one aspect, at least one embodiment of the present disclosure provides an apparatus for polishing the surface of an insulating board, comprising:

[0007] The equipment rack and the top frame, wherein the top frame is fixed to the equipment rack;

[0008] A polishing assembly, the polishing assembly being mounted on the top frame;

[0009] A pair of side frames and a clamping and pushing assembly, wherein the side frames are fixed on both sides of the equipment frame and the clamping and pushing assembly is disposed on the equipment frame and the side frames;

[0010] The clamping and pushing assembly includes a pair of guide rods, both of which are fixed between the inner side of the side frame and the equipment frame. A side support frame is slidably connected to the guide rod, and a number of conveying wheels are provided at the bottom of the side support frame. The conveying wheels at the front and rear ends are driven to rotate by electricity.

[0011] As a further technical solution, a drive screw is rotatably connected inside the equipment frame, and both ends of the drive screw are rotatably connected to the side frame. The drive screw is rotated by electric control, and the side support frame is connected to the drive screw by a threaded connection.

[0012] As a further technical solution, a horizontal shaft is rotatably connected inside the equipment frame, and several support wheels are provided on the horizontal shaft. One end of the horizontal shaft passes through the side frame and is connected to one side of the side frame. The horizontal shaft is driven to rotate by electricity.

[0013] As a further technical solution, the polishing assembly includes a pair of drive shafts, both of which are rotatably connected within the top frame. One of the drive shafts is driven to rotate by electricity, and each drive shaft has a transmission gear at one end, with the transmission gears meshing with each other.

[0014] As a further technical solution, two sets of vertical shafts are rotatably connected in the top frame. Each vertical shaft is provided with a driven gear at its upper end. Several drive gears are provided on the drive shaft. All drive gears mesh with the driven gears. A polishing disc is provided at the lower end of the vertical shaft.

[0015] As a further technical solution, the adjacent polishing discs are arranged in a staggered manner from left to right.

[0016] As a further technical solution, the conveying wheel and the supporting wheel are at a 90° angle to each other, and the surface of the conveying wheel is an anti-slip structural surface with high friction.

[0017] As a further technical solution, the polishing disc is inserted into the lower end of the vertical shaft, and the connection between the polishing disc and the vertical shaft is fixed by bolts.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the clamping and pushing assembly automatically adjusts the spacing between the conveyor wheels to accommodate insulating boards of different widths through the threaded engagement of the drive screw and the side support frame. This eliminates the need for precise manual positioning and complex clamping, solving the problem of cumbersome feeding in traditional equipment. The conveyor wheels and support wheels are distributed at 90°, and the anti-slip structure on the surface of the conveyor wheels provides stable driving force. The support wheels support the insulating boards, ensuring that the boards do not slip or warp during conveying, achieving continuous automatic feeding, reducing manual intervention, improving production efficiency, and lowering labor costs and operational difficulty.

[0020] In this disclosure, the polishing assembly uses a drive shaft and transmission gears to drive two sets of vertical shafts, which in turn rotate the polishing discs at high speed. Adjacent polishing discs are staggered left and right, achieving blind-spot-free polishing of the insulating board surface, improving polishing uniformity and surface finish. The polishing discs are inserted into and fixed to the vertical shafts with bolts, facilitating quick replacement of discs with different abrasives. This meets the multi-stage processing requirements from coarse to fine polishing, improves the equipment's process adaptability, ensures the polishing quality of the insulating board, reduces the risk of surface damage due to clamping, and is suitable for polishing various insulating materials.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-3 As shown, it illustrates an insulating board surface polishing apparatus according to an embodiment of the present disclosure, comprising:

[0033] Equipment frame 1 and top frame 2, wherein the top frame 2 is fixed on the equipment frame 1;

[0034] Polishing assembly 5, which is mounted on the top frame 2;

[0035] A pair of side frames 3 and a clamping and pushing assembly 4, wherein the side frames 3 are fixed on both sides of the equipment frame 1, and the clamping and pushing assembly 4 is disposed on the equipment frame 1 and the side frames 3;

[0036] The clamping and pushing assembly 4 includes a pair of guide rods 4-1, both of which are fixed between the inner side of the side frame 3 and the equipment frame 1. A side support frame 4-2 is slidably connected to the guide rod 4-1. Several conveying wheels 4-3 are provided at the bottom of the side support frame 4-2. The conveying wheels 4-3 at both ends are driven to rotate by electricity. A drive screw 4-4 is rotatably connected inside the equipment frame 1. Both ends of the drive screw 4-4 are rotatably connected to the side frame 3. The drive screw 4-4 is controlled to rotate by electricity. The side support frame 4-2 and the drive screw 4-4 are connected by a threaded connection. A horizontal shaft 4-5 is rotatably connected inside the equipment frame 1. Several support wheels 4-6 are provided on the horizontal shaft 4-5. One end of the horizontal shaft 4-5 passes through the side frame 3 and is connected to one side of the side frame 3. The horizontal shaft 4-5 is driven to rotate by electricity.

[0037] In some examples, to achieve stable conveying of the insulating board and a stable polishing effect, a clamping and pushing assembly 4 is designed. This assembly includes a pair of guide rods 4-1 fixed between the equipment frame 1 and the side frame 3, providing a horizontal sliding guide for the side support frame 4-2. The conveying wheels 4-3 at the bottom of the side support frame 4-2 are arranged in two rows. The conveying wheels 4-3 at the front and rear ends are driven by a motor, forming a stable friction force to drive the insulating board forward. The threads at both ends of the drive screw 4-4 are opposite in direction and have a threaded engagement structure with the side support frame 4-2. The spacing of the side support frame 4-2 can be precisely controlled by forward and reverse rotation to accommodate insulating boards of different widths.

[0038] The horizontal shaft 4-5 and support wheel 4-6 within the equipment frame 1 form the bottom support. The horizontal shaft 4-5 is rotated by a motor, ensuring that the linear speed of the support wheel 4-6 is consistent with that of the conveyor wheel 4-3. When the insulating board is clamped by the side support frame 4-2, the support wheel 4-6 rotates synchronously to provide upward support, preventing the board from sagging due to its own weight. The conveyor wheel 4-3 rotates synchronously with the support wheel 4-6, allowing the board to pass smoothly through the polishing area, providing a fundamental guarantee for high-quality polishing.

[0039] like Figures 1-3 As shown in the figure, the polishing assembly 5 in this embodiment includes a pair of drive shafts 5-1, both of which are rotatably connected to the top frame 2. One of the drive shafts 5-1 is driven to rotate by electricity. One end of each drive shaft 5-1 is provided with a transmission gear 5-2, which meshes with each other. Two sets of vertical shafts 5-3 are rotatably connected in the top frame 2. Each vertical shaft 5-3 is provided with a driven gear 5-4 at its upper end. Several drive gears 5-5 are provided on the drive shaft 5-1, and each drive gear 5-5 meshes with the driven gear 5-4. A polishing disc 5-6 is provided at the lower end of the vertical shaft 5-3.

[0040] In some examples, to achieve efficient polishing of the insulating board surface, a polishing assembly 5 is designed. This assembly includes a pair of drive shafts 5-1 disposed within the top frame 2. One of the drive shafts is driven by a motor, and the drive shaft 5-1 drives the other shaft to rotate in the opposite direction via a transmission gear 5-2, forming a symmetrical power output. The drive gear 5-5 on the drive shaft 5-1 meshes with the driven gear 5-4 at the upper end of the vertical shaft 5-3, converting the horizontal rotational motion into high-speed rotation of the vertical shaft 5-3, causing the polishing disc 5-6 at the lower end to generate a grinding force.

[0041] Two sets of vertical shafts 5-3 are arranged in a staggered pattern, allowing for rough or fine polishing of the insulating board surface. For example, when the insulating board passes under the polishing discs 5-6, the front polishing discs 5-6 first remove surface burrs and scratches, while the rear polishing discs 5-6 further improve the surface finish. The module-matched design of the drive gear 5-2 and driven gear 5-4 ensures uniform pressure distribution on the polishing discs 5-6, preventing localized overheating that could lead to deformation of the insulating material. This design is suitable for surface treatment of various insulating boards, including those made of phenolic resin and epoxy resin.

[0042] For example, such as Figure 3 As shown, the adjacent polishing discs 5-6 are staggered from left to right.

[0043] In some examples, adjacent polishing pads 5-6 are arranged in a staggered manner, achieving blind-spot-free polishing of the insulating board surface through the overlapping of their coverage areas. This layout makes the grinding trajectories of the polishing pads 5-6 distributed in a mesh pattern, avoiding polishing streaks caused by straight-line arrangement.

[0044] For example, such as Figure 1 As shown, the conveying wheel 4-3 and the support wheel 4-6 are at a 90° angle to each other, and the surface of the conveying wheel 4-3 is an anti-slip structure with high friction.

[0045] In some examples, the conveyor wheel 4-3 and the support wheel 4-6 are distributed perpendicularly at 90°. The anti-slip structure on the surface of the conveyor wheel 4-3 and the smooth surface of the support wheel 4-6 form a clamping support system. The two conveyor wheels 4-3 provide forward driving force through the anti-slip surface, and the bottom support wheel 4-6 simultaneously lifts the plate. The 90° force layout ensures that the plate does not slip or warp during the conveying process. With the spacing adjustment of the drive screw 4-4, it can adapt to the stable conveying of plates of different specifications and provide a precise position reference for the polishing process.

[0046] For example, such as Figure 2 As shown, the polishing disc 5-6 is inserted into the lower end of the vertical shaft 5-3, and the connection between the polishing disc 5-6 and the vertical shaft 5-3 is fixed by bolts.

[0047] In some examples, the polishing disc 5-6 is connected to the lower end of the vertical shaft 5-3 by an insert and is secured with bolts. This detachable design facilitates quick replacement of polishing discs 5-6 with different abrasives. When it is necessary to switch from coarse polishing to fine polishing, the old polishing disc 5-6 can be removed by loosening the bolts, and the new disc can be installed and then tightened again. The replacement process only takes 5 to 10 minutes, which significantly improves the process adaptability of the equipment and can meet the multi-stage processing needs of the insulation board surface from rough processing to mirror polishing.

[0048] In actual use: The insulating board is placed on the support wheels 4-6 inside the equipment frame 1. The electric drive device of the drive screw 4-4 is started, and the drive screw 4-4 rotates, causing the side support frame 4-2 to slide along the guide rod 4-1. This causes the conveying wheels 4-3 at the bottom of the side support frame 4-2 to fit against both sides of the insulating board. The conveying wheels 4-3 at both ends are electrically driven to rotate, clamping the insulating board forward through friction. At the same time, the drive shaft 5-1 of the polishing assembly 5 is electrically driven to rotate, driving another drive shaft 5-1 to rotate in the opposite direction through the transmission gear 5-2. The drive gear 5-5 on the drive shaft 5-1 meshes with the driven gear 5-4 at the upper end of the vertical shaft 5-3, causing the polishing disc 5-6 at the lower end of the vertical shaft 5-3 to rotate at high speed. The adjacent staggered polishing discs 5-6 polish the surface of the insulating board in sequence. The polished insulating board is then sent out of the equipment frame 1 by the conveying wheels 4-3, completing the polishing operation.
