Description

Technical Field

[0001] This invention relates to the field of ceramic resistor manufacturing technology, and more specifically to a ceramic resistor surface polishing device. Background Technology

[0002] Ceramic resistors are fixed resistors with ceramic as the matrix and metal oxide as the resistive element. They have advantages such as small size, high stability, and high temperature resistance, and are widely used in various electronic devices, such as radios, power amplifiers, power modules, and LED driver circuits. During the production of ceramic resistors, the surface needs to be polished, which requires the use of polishing equipment.

[0003] Currently, existing polishing equipment has been found to have a polishing box that can only rotate in one direction. This causes the polishing ball and ceramic resistor to rotate in the same direction during polishing, resulting in unsatisfactory polishing results, the creation of polishing dead corners, and poor chip removal. Therefore, improvements are needed.

[0011] Preferably, an L-shaped frame is fixedly connected to the top of the movable plate, and a pipe is fixedly connected between the second box and the L-shaped frame. One end of the pipe is embedded in the top of the first box and connected to it through a sealed bearing.

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See attached document Figure 1 -Appendix Figure 11 The present invention provides a ceramic resistor surface polishing device, including a frame 1 and a support 2 fixedly connected to the top of the frame 1. A bottom shell 3 is fixedly embedded on the frame 1, and a flow guide 4 is provided on the bottom inner wall of the bottom shell 3. Inside the bottom shell 3, a ring 5 is connected by a bearing. A polishing box 6 is placed on the ring 5. A mesh plate 7 is fixedly embedded at the bottom of the polishing box 6, and an annular guide block 8 is fixedly connected to the inner wall of the bottom of the polishing box 6. Four hydraulic cylinders 9 are fixedly embedded on the bracket 2, and a moving plate 10 is fixedly connected to the bottom of the four hydraulic cylinders 9. A pressure block 11 is fixedly connected to the bottom of the moving plate 10. The movable plate 10 is equipped with a driving component, and the pressure block 11 is equipped with a flipping component, with the lower half of the flipping component located inside the polishing box 6; In this embodiment, when polishing the ceramic resistor sheet, the ceramic resistor sheet and polishing ball are placed in the polishing box 6, with a volume ratio of 7:3 for the ceramic resistor sheet and polishing ball 47. Then, four electric push rods are controlled to move the moving plate 10, the pressure block 11, and the flipping component downwards. In this way, the pressure block 11 presses against the top of the polishing box 6, and the lower half of the flipping component moves into the polishing box 6. The driving component controls the pressure block 11, the flipping component, and the polishing box 6 to reciprocate to polish the ceramic resistor sheet. At the same time, the driving component can also make the flipping component work to flip the ceramic resistor sheet to avoid the ceramic resistor sheets being piled up in the same state, thus avoiding polishing dead corners. During polishing, debris is generated. Since a mesh plate 7 and annular guide block 8 are set at the bottom of the polishing box 6, the debris moves towards the mesh plate 7 under the action of the annular guide block 8, and then falls into the bottom shell 3 through the mesh plate 7. This can prevent the debris from staying in the polishing box 6 for a long time, so as to avoid the debris from repeatedly rubbing the surface of the resistor sheet with the polishing ball and causing secondary scratches. In this embodiment, a conveying box 48 is fixedly embedded inside the bottom shell 3, and a material trough is opened between the conveying box 48 and the bottom shell 3. A servo motor 49 is fixedly connected to one side of the conveying box 48, and a rotating shaft 50 is fixedly connected to the output shaft of the servo motor 49. The rotating shaft 50 passes through the conveying box 48, and a spiral blade 51 is fixedly sleeved on the outside of the rotating shaft 50. The spiral blade 51 is set inside the conveying box 48, and a discharge pipe 52 is fixedly embedded at the bottom of the conveying box 48. The rotating shaft 50 is connected to the conveying box 48 through a sealed bearing. It should be noted that the bottom inner wall of the bottom shell 3 is provided with a guide section 4. When the debris falls into the bottom shell 3, it can enter the material trough under the action of the guide section 4 and then enter the conveying box 48. At this time, the servo motor 49 can be controlled to make the rotating shaft 50 and the spiral blade 51 rotate, thereby conveying the debris to the right. In this way, the debris can be discharged through the discharge pipe 52. Specifically, the driving component includes a U-shaped frame 12, which is fixedly connected to the bottom of the moving plate 10. A servo motor 13 is fixedly connected to the front side of the U-shaped frame 12. A reciprocating screw 14 is fixedly connected to the output shaft of the servo motor 13, and the reciprocating screw 14 passes through the U-shaped frame 12. A slider 15 is sleeved on the outside of the reciprocating screw 14 for use with it. A crossbar 16 is fixedly connected to one side of the pressure block 11, and a groove is opened on the crossbar 16. A protruding rod 17 is fixedly connected to the top of the slider 15, and the protruding rod 17 passes through the groove. A limiting rod 18 is fixedly connected to the inner wall of the bottom of the U-shaped frame 12. The limiting rod 18 passes through the slider 15 and slides in contact with it. The reciprocating screw 14 and the U-shaped frame 12 are connected by bearings. It should be noted that during polishing, controlling the servo motor 13 will cause the reciprocating screw 14 to rotate. The rotation of the reciprocating screw 14 drives the slider 15 to move back and forth. The back and forth movement of the slider 15 drives the protruding rod 17 to move back and forth. Since the protruding rod 17 passes through the groove on the crossbar 16, the back and forth movement of the protruding rod 17 will cause the pressure block 11 to rotate back and forth. Because the pressure block 11 presses against the polishing box 6, and the pressure block 11 is connected to the moving plate 10 through a bearing, the back and forth rotation of the pressure block 11 will cause the polishing box 6 to rotate back and forth, instead of rotating in one direction. By driving the polishing box 6 to perform reciprocating forward and reverse motion, the inertial motion trajectory of the polishing ball and the ceramic resistor sheet in a single direction can be broken. When the polishing box 6 is changed... When the device rotates, the polishing balls and ceramic resistors inside the box will briefly slide in opposite directions due to inertia. At the same time, the lower half of the flipping component is located in the polishing box 6. When the polishing box 6 turns, it disturbs the material inside. The flipping component will push and disperse the gathered polishing balls and ceramic resistors, causing the ceramic resistors that were originally in the gaps between the polishing balls or on the surface to be stirred to different positions. The resistors that were originally attached to the inner wall of the polishing box 6 will be replaced to the middle layer of the material. This allows each ceramic resistor to collide and rub against different polishing balls in multiple directions and angles during the polishing process, avoiding local over-polishing or blind spots caused by a fixed direction of movement, and effectively improving the uniformity and overall quality of the ceramic resistor surface polishing. Specifically, the flipping component includes a housing 19 fixedly embedded in the pressure block 11. A through groove is provided at the bottom of the housing 19. A piston 20 is slidably disposed inside the housing 19, and a moving rod 21 penetrating the through groove is fixedly connected to the bottom of the piston 20. The moving rod 21 slides in contact with the through groove. A moving block 22 is fixedly connected to the bottom end of the moving rod 21. The bottom of the moving block 22 has a sharp point 23, and the top of the moving block 22 has an inclined portion 24. The flipping component also includes a turntable 25 fixedly connected to the rear end of a reciprocating screw 14 and a vertical rod 26 fixedly connected to the bottom of the U-shaped frame 12. A housing is fixedly connected to the rear side of the vertical rod 26. The top of the housing 27 is fixedly connected to a guide frame 28. Inside the housing 27, a piston 29 is slidably installed. The top of the piston 29 is fixedly connected to a moving rod 30 that passes through the guide frame 28 and slides in contact with it. The rear side of the turntable 25 and the top of the moving rod 30 are both fixedly connected to a connecting rod 31. The two connecting rods 31 are fitted with a pull rod 32, and the pull rod 32 is connected to the two connecting rods 31 through a bearing. The top of the moving plate 10 is fixedly connected to an L-shaped frame 33. A pipe 34 is fixedly connected between the housing 27 and the L-shaped frame 33. One end of the pipe 34 is embedded in the top of the housing 19 and connected to it through a sealed bearing. It should be noted that when the reciprocating screw 14 rotates, the turntable 25 can also rotate. Since the pull rod 32 is connected to the two connecting rods 31 through bearings, they can move. Thus, under the action of the pull rod 32, the rotation of the turntable 25 can continuously pull the second moving rod 30 and the second piston 29 to move up and down. Then, under the action of the first pipe 34, the second piston 29 moves up and down, which can make the air in the second housing 27 and the first housing 19 flow back and forth. When the air flows back and forth, it can make the first piston 20, the first moving rod 21 and the moving block 22 move up and down. When the moving block 22 moves up and down, it moves up and down in the grinding ball and the ceramic resistor. Thus, when it moves, it can flip the grinding ball and the ceramic resistor. In addition, the bottom of the moving block 22 is provided with a sharp part 23 and the top of the moving block 22 is provided with an inclined part 24. That is to say, the bottom of the moving block 22 is sharp and the top is inclined from the middle to the four sides. The sharp point 23 at the bottom of the moving block 22 can easily pierce the gap between the stacked grinding balls and ceramic resistors. When moving downwards, it can quickly break up any clumps of material, preventing the material from forming a fixed pile due to compression. The inclined part 24 at the top of the moving block 22, which slopes from the center to the surrounding areas, will push the surrounding grinding balls and ceramic resistors to the surrounding areas and divert the material during the upward movement. This will lift the ceramic resistors that were originally at the bottom layer to the middle or surface layer, while the material on the surface will be squeezed into the bottom layer. Combined with the reciprocating rotation of the polishing box 6, the movement trajectory of the material can be further disrupted. This dual effect of downward piercing and dispersion combined with upward diversion ensures that each ceramic resistor can fully contact the grinding balls, effectively reducing the polishing blind zone, significantly improving the uniformity and efficiency of the turning, and thus increasing the polishing quality. During polishing, debris is continuously generated and adheres to the inner wall of the polishing box 6. Therefore, in this embodiment, striking components are provided on both sides of the moving rod 21. Each striking component includes a housing 35, with a connecting block 36 fixedly connected between the housing 35 and the box body 19. A transverse moving rod 37 is slidably embedded on the side of the housing 35 closest to the moving rod 21, and a transverse moving rod 38 is slidably embedded on the side away from the moving rod 21. A protruding plate 39 is fixedly sleeved on the outside of the transverse moving rod 38, and the protruding plate 39 is slidably disposed inside the housing 35. The protruding plate 39 and the housing 35 are located away from the moving rod 21. A spring 40 is fixedly connected between one side of the horizontal moving rod 38 and the horizontal moving rod 37. A spring 41 is fixedly connected between the horizontal moving rod 38 and the horizontal moving rod 37. The elastic force of the spring 41 is greater than that of the spring 40. A slot is provided inside the horizontal moving rod 38. A plug rod 42 is fixedly connected to one end of the horizontal moving rod 37. The plug rod 42 is slidably inserted into the slot. The spring 40 is sleeved on the outside of the horizontal moving rod 38. The spring 41 is sleeved on the outside of the plug rod 42. A vertical rod 43 is fixedly connected to one side of the moving rod 21. A wave part 44 is provided on the side of the vertical rod 43 near the horizontal moving rod 37. The end of the horizontal moving rod 37 is in sliding contact with the wave part 44. It should be noted that when the moving rod 21 moves up and down, it can drive the vertical rod 43 to move up and down. Since the vertical rod 43 is provided with a wave part 44, and the elastic force of the second spring 41 is greater than that of the first spring 40, when the vertical rod 43 moves up and down, the convex end of the wave part 44 can squeeze the components such as the first horizontal moving rod 37, the second spring 41, the second horizontal moving rod 38, the convex plate 39, and the insert rod 42, causing them to move towards the inner wall of the polishing box 6. In this way, the end of the second horizontal moving rod 38 can impact the inner wall of the polishing box 6. At the same time, the first spring 40 is compressed. When the end of the first horizontal moving rod 37 contacts the concave end of the wave part 44, the above parts can be reset under the action of the spring 40. This cycle can continuously strike the inner wall of the polishing box 6, thereby causing the polishing box 6 to produce slight vibrations, which can prevent debris from adhering. As described above, the synergistic effect of the reciprocating rotation of the polishing box 6, the flipping of the moving block 22, and the tapping of the inner wall can achieve rapid discharge of debris from three aspects: disturbance, separation, and guidance. In terms of disturbance, the reciprocating rotation of the polishing box 6 breaks the unidirectional inertia of the material, and the tapping of the inner wall generates high-frequency vibration, both of which shake off debris adhering to the box wall and disrupt the material's accumulation state. In terms of separation, the moving block 22 uses its sharp part 23 to break up material clumps and its inclined part 24 to divert the grinding balls and resistance sheet, peeling away debris wrapped in the material. In terms of guidance, the reciprocating rotation drives the debris to migrate to the bottom, and the vibration transmission not only accelerates the migration efficiency but also prevents the mesh plate 7 from becoming clogged, allowing the debris to be smoothly discharged along the mesh plate 7. This prevents debris from remaining in the polishing box 6 for a long time and causing secondary damage to the ceramic resistance sheet. In addition, to ensure the striking effect, the distance between the end of the second horizontal moving rod 38 and the inner wall of the polishing box 6 is less than the length of the convex end of the wave section 44. This arrangement would result in the end of the first horizontal moving rod 37 not completely passing over the convex end of the wave section 44 after the end of the second horizontal moving rod 38 contacts the inner wall. Therefore, a second spring 41 and a plug rod 42 that can be inserted into a slot are provided between the first horizontal moving rod 37 and the second horizontal moving rod 38. In this way, when striking, that is, after the end of the second horizontal moving rod 38 contacts the inner wall, the distance between the second horizontal moving rod 38 and the first horizontal moving rod 37 will shrink, thus ensuring that the end of the first horizontal moving rod 37 smoothly passes over the convex end of the wave section 44. Among them, the elastic force of the second spring 41 is greater than that of the first spring 40, so that the second spring 41 is not compressed before the first spring 40 during striking, thereby avoiding insufficient striking force. In this device, the pressure block 11 needs to be pressed on the polishing box 6 when in use. In order to ensure the pressing effect of the bracket 2 and to ensure that the polishing box 6 rotates synchronously with the pressure block 11, in this embodiment, the bottom of the pressure block 11 is provided with an annular groove, and an annular air cushion 45 is fixedly connected inside the annular groove. The top of the polishing box 6 extends into the annular groove, and the top of the polishing box 6 is provided with a plurality of circumferentially evenly distributed protrusions 46. It should be noted that when the pressure is applied, the annular air cushion 45 contacts multiple protrusions 46, and the elastic deformation of the annular air cushion 45 fits tightly with the protrusions 46, thus ensuring that the polishing box 6 rotates synchronously with the pressure block 11. During polishing, the polishing box 6 needs to be rotated back and forth. In order to reduce the friction between the polishing box 6 and the bottom shell 3, in this embodiment, a plurality of circumferentially evenly distributed spheres 47 are movably embedded in the inner wall of the bottom shell 3, and the plurality of spheres 47 are in contact with the outer side of the polishing box 6. It should be noted that the polishing box 6 is placed on the ring 5, and the ring 5 is connected to the bottom shell 3 through a bearing. When pressed, it can ensure that the polishing box 6 can rotate normally back and forth. In addition, a ball 47 is set on the bottom shell 3, and the ball 47 is in active contact with the bottom shell 3 and the polishing box 6. This can reduce the friction between the polishing box 6 and the bottom shell 3 during reciprocating rotation.

[0024] After polishing is completed, control the servo motor 13 to stop the moving block 22 at the highest point, and then control the four hydraulic cylinders 9 to move the moving plate 10, the pressure block 11 and the flipping parts out of the polishing box 6. Then remove the polishing box 6, place a new polishing box 6 on the polishing box 6, and finally repeat the above steps to polish again.

[0025] The above are merely preferred embodiments of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
