Description

Technical Field

[0001] This invention relates to the field of grinding and positioning technology, specifically to a mechanical grinding and positioning fixture for a cathode plate surface. Background Technology

[0002] Before use, the cathode plate needs to be ground to improve its flatness and surface quality. When grinding the cathode plate surface, a cathode plate surface grinding machine is required. The grinding machine is usually equipped with a simple positioning fixture to position the cathode plate.

[0003] When existing positioning fixtures limit the cathode plate, they generally place the tabs at both ends of the cathode plate between the stop bars on the positioning fixture. The stop bars limit the tabs, thereby limiting the cathode plate. Then, the positioning fixture pushes the cathode plate closer to the double-sided polishing machine, so that the cathode plate is inserted into the feed port of the double-sided polishing machine.

[0004] However, in actual operation, there may be quality defects in the cathode plate after grinding and polishing.

[0005] Analysis revealed that when the cathode plate was pushed into the double-sided polishing machine, the positioning fixture could only support one side of the cathode plate with the mounting tabs, leaving the other side suspended. As a result, the cathode plate would sag and bend due to its own weight, causing its lower surface to scrape against the equipment's support track or platform. This would scratch the cathode plate surface before polishing. The suspended part would also generate unstable vibrations during the pushing process, which could cause the cathode plate to get stuck or shift its position when it enters the machine.

[0006] Furthermore, by using a stop bar to simply limit the tabs on both sides of the cathode plate, when the cathode plate enters the double-sided polishing machine for grinding, the cathode plate will slide and drift on the support platform under the driving force of the rotating friction of the grinding disc, resulting in quality defects in the grinding of the cathode plate surface.

[0007] In addition, it was found that the cathode plate could not be effectively clamped. Without clamping force to press the cathode plate onto the positioning fixture, the cathode plate would experience high-frequency vibration or low-frequency jumping when subjected to the periodic pressure and unbalanced grinding force of the grinding disc. This high-frequency vibration would hinder smooth polishing, leading to deterioration of surface roughness, resulting in micro-vibration marks, pits or "orange peel" defects, and even causing subsurface damage such as microcracks.

[0008] Based on this, the present invention provides a mechanical grinding and positioning fixture for the cathode plate surface to solve the above problems. Summary of the Invention

[0020] The present invention has the following technical effects.

[0021] 1. This invention provides overall support for the cathode plate through an active pusher plate and an auxiliary pusher plate, ensuring that it remains flat during transportation and reducing bending deformation caused by suspension. Through the cylinder, tension spring, guide rod and adjusting baffle, the active pusher plate and the auxiliary pusher plate can move closer to each other, thereby smoothly pushing the cathode plate to the grinding station in the double-sided polishing machine.

[0022] 2. The present invention, through the support, fixing bolts, adjusting groove and fixing groove, can flexibly adjust the distance between the active push plate and the auxiliary push plate according to the processing requirements of cathode plates of different sizes.

[0023] 3.

[0024] 4. This invention uses a motor, a drive wheel, a belt, and a driven wheel to drive the active push plate and the auxiliary push plate to move synchronously toward the double-sided polishing machine, thereby achieving stable and automatic feeding of the cathode plate and improving the continuity and positioning accuracy of the feeding process.

Detailed Implementation

[0038] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 11 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0039] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0040] This invention relates to a mechanical grinding and positioning fixture for a cathode plate. Existing positioning fixtures are prone to bending, scratching, and jamming during the transport and positioning stage due to the cathode plate being suspended on one side. Furthermore, unstable positioning causes the cathode plate to slide and rotate during grinding, resulting in uneven thickness and out-of-tolerance dimensions.

[0041] During the grinding and pressurization stage, the cathode plate vibrates due to the lack of effective clamping, which disrupts the polishing stability and leads to defects such as vibration marks, pitting, orange peel texture, and even microcracks on the surface.

[0042] As an example, such as Figure 1 , Figures 3-6As shown, the present invention includes a base 1, a double-sided polishing machine 2, a support frame 5, a bearing frame 6, and a track 7. An active push plate 8 and an auxiliary push plate 9 are slidably connected on the track 7. Two cylindrical bodies 39 are fixedly connected to the bottom of the active push plate 8. Each of the two cylindrical bodies 39 has an installation groove 40 on the side away from the auxiliary push plate 9 and a through hole 42 on the side closer to the auxiliary push plate 9. The two installation grooves 40 are respectively connected to the two through holes 42. Guide rods 43 are fixedly connected to both sides of the bottom of the auxiliary push plate 9. The two guide rods 43 are slidably connected in the two through holes 42 and pass through the cylindrical bodies 39. A fixed baffle 44 and an adjusting baffle 45 are fixedly connected to each of the two guide rods 43. The fixed baffle 44 is located between the auxiliary push plate 9 and the cylindrical bodies 39. The adjusting baffle 45 is circular and matches the shape of the installation groove 40. The cylindrical bodies 39 can slide on the guide rods 43 between the fixed baffle 44 and the adjusting baffle 45. A tension spring 41 is provided in each of the two installation grooves 40.

[0043] In this embodiment, during the polishing operation, the cathode plate is placed on the active push plate 8 and the auxiliary push plate 9. During the advancement process, the active push plate 8 and the auxiliary push plate 9 drive the cathode plate to move towards the double-sided polishing machine 2 until the slide rail of the auxiliary push plate 9 contacts the support frame 5 and is blocked. At this time, the active push plate 8 continues to move forward, driving the cylinder 39 below the active push plate 8 to slide on the guide rod 43 and contact the fixed baffle 44 on the guide rod 43. At this time, the cathode plate has been smoothly pushed into the polishing machine for polishing.

[0044] During the closing process of the active push plate 8 and the auxiliary push plate 9, the cylinder 39 slides along the guide rod 43 and works with the adjusting baffle 45 to stretch the tension spring 41, allowing it to store elastic potential energy. This ensures that after grinding, when the active push plate 8 reverses and resets, it can first separate from the auxiliary push plate 9. When the tension spring 41 returns to its initial state, the auxiliary push plate 9 will then retract accordingly, restoring the initial distance between the active push plate 8 and the auxiliary push plate 9, thus preparing for the subsequent placement and pushing of the cathode plate.

[0045] During this process, the active push plate 8 and the auxiliary push plate 9 provide excellent support for the cathode plate during initial placement and before it enters the double-sided polishing machine 2, preventing one end of the cathode plate from sagging. When the cathode plate just enters the double-sided polishing machine 2, the auxiliary push plate 9 continues to provide support to ensure that the cathode plate remains flat and stable before polishing.

[0046] As an example, such as Figure 5 and Figure 6As shown, one end of each of the two tension springs 41 is fixedly connected to one side of the mounting groove 40, and the other end of each of the two tension springs 41 is fixedly connected to one side of the adjusting baffle 45. The top of each of the two guide rods 43 is provided with an adjusting groove 48, which is rectangular. The bottom of the adjusting groove 48 is provided with multiple fixing grooves 49, which are circular and match the bottom of the fixing bolts 47. One side of each of the two adjusting baffles 45 is fixedly connected with a support 46, and each of the two supports 46 is provided with a fixing bolt 47. The two fixing bolts 47 respectively cooperate with the fixing grooves 49 in the two adjusting grooves 48. The adjusting baffles 45 are fixed to the guide rods 43 by the fixing bolts 47.

[0047] As an example, such as Figure 2 and Figure 7 As shown, the auxiliary push plate 9 has a working groove 50 on the side away from the active push plate 8. The working groove 50 is rectangular. Two support plates 51 are fixedly connected to the bottom of the auxiliary push plate 9. A fixed rod 54 is fixedly connected between the two support plates 51. A rotating frame 52 is rotatably connected to the fixed rod 54. A torsion baffle 53 is fixedly connected to one side of the rotating frame 52. The torsion baffle 53 is located in the working groove 50. Two torsion springs 55 are provided on the fixed rod 54. One end of the two torsion springs 55 is fixedly connected to the opposite side of the two support plates 51, and the other end of the two torsion springs 55 is fixedly connected to both sides of the rotating frame 52. The two support plates 51 limit the rotating frame 52 through the torsion springs 55.

[0048] In this embodiment, to accommodate cathode plates of different sizes, the operator can loosen the fixing bolts 47 on the support 46 and push the adjusting baffle 45 to slide along the guide rod 43, thereby adjusting the distance between the fixing baffle 44 and the adjusting baffle 45. After adjustment, the fixing bolts 47 are reinstalled on the support 46 so that their ends are embedded in the corresponding fixing grooves 49, thus locking the position of the adjusting baffle 45. This ensures that the positioning fixture is suitable for cathode plates of different widths. When the cathode plate is placed on the active push plate 8 and the auxiliary push plate 9 for feeding, one side of the cathode plate... The cathode plate will contact the torsion baffle 53. As the active push plate 8 moves towards the double-sided polishing machine 2, the cathode plate pushes the torsion baffle 53, which in turn moves the auxiliary push plate 9 forward in sync. When the auxiliary push plate 9 is blocked by the support frame 5, the active push plate 8 continues to push the cathode plate forward, forcing the torsion baffle 53 to rotate around the fixed rod 54 and be stored in the working groove 50 to avoid collision. At this time, the rotating frame 52 compresses the torsion spring 55 to store energy. After the cathode plate is polished and returns to its original position, the torsion spring 55 releases energy and drives the torsion baffle 53 to automatically reset, preparing for the next round of cathode plate placement.

[0049] When the cathode plate is initially placed, the twisting baffle 53 can limit and stabilize the limit. During the limit movement, the twisting baffle 53 can make the auxiliary push plate 9 and the active push plate 8 move synchronously.

[0050] As an example, such as Figure 3 and Figure 8 As shown, fixed stop bars 17 are fixedly connected to both sides of the top of the active push plate 8. Two limit frames 18 are fixedly connected to the side of the active push plate 8 near the auxiliary push plate 9. Both limit frames 18 are annular and inclined. Adjustable stop bars 19 are slidably connected inside the two limit frames 18. The fixed stop bars 17 and the adjustable stop bars 19 have the same shape. The bottom of the adjustable stop bars 19 is provided with a fixed seat that can slide inside the limit frame 18. The two adjustable stop bars 19 cooperate with the two fixed stop bars 17 respectively.

[0051] As an example, such as Figure 8 and Figure 9 As shown, an arc-shaped push rod 20 is rotatably connected to the bottom of one side of each of the two adjusting levers 19. The top of the arc-shaped push rod 20 is lower than the top of the active push plate 8 to avoid the pressure of the cathode plate affecting the movement and adjustment of the arc-shaped push rod 20. Two sliding grooves 21 are opened on the top of the active push plate 8. The two sliding grooves 21 are located on the same straight line on the top of the active push plate 8. Sliding seats 22 are slidably connected in both sliding grooves 21. The other ends of the two arc-shaped push rods 20 are rotatably connected to one side of the two sliding seats 22 respectively. Straight push rods 23 are rotatably connected to the top of the two sliding seats 22.

[0052] As an example, such as Figure 3 and Figure 9 As shown, a top plate 16 is fixedly connected to the side of the active push plate 8 near the auxiliary push plate 9. The top plate 16 is rectangular. A fixing plate 24 is fixedly connected to the top of the top plate 16. An electric push rod 25 is fixedly connected to the side of the fixing plate 24 away from the auxiliary push plate 9. A push frame 26 is fixedly connected to the output end of the electric push rod 25. The other ends of the two straight push rods 23 are rotatably connected to the bottom of the push frame 26.

[0053] In this embodiment, after the cathode plate is placed on top of the active push plate 8 and the auxiliary push plate 9, its two tabs are located between the fixed stop rod 17 and the adjusting stop rod 19. Then, the electric push rod 25 is operated, and the output end of the electric push rod 25 extends, pushing the push frame 26 to move away from the fixed plate 24. Thus, the push frame 26 pulls the two straight push rods 23 to move synchronously, driving the connected sliding seat 22 to move inward along the slide groove 21. When the two sliding seats 22 slide close together in the slide groove 21, they drive the arc-shaped push rod 20 on one side to move closer to each other. The arc-shaped push rod 20 then pulls the adjusting stop rod 19 to slide along the limiting frame 18, making it move towards the fixed stop rod 17. During this process, the adjusting stop rod 19 not only clamps the tabs longitudinally, but also moves inward synchronously, applying a lateral clamping force to the cathode plate, thereby forming a bidirectional positioning constraint, effectively preventing the cathode plate from shifting during the grinding process and ensuring the processing position.

[0054] After processing, the output end of the electric push rod 25 is shortened, which drives the two straight push rods 23 to push the two sliding seats 22 to slide in opposite directions in the two sliding grooves 21 respectively. The two sliding seats 22 move away from each other, which drives the two arc push rods 20 to push the two adjusting rods 19 away from each other, thereby loosening the clamped cathode plate and electrode ear, making it easy to remove the cathode plate.

[0055] It should be noted that the electric actuator 25 is connected to a power supply and a controller.

[0056] As an example, such as Figures 8-10 As shown, an active pull rod 27 is fixedly connected to the bottom of the push frame 26, and a driven pull rod 28 is rotatably connected to the bottom of the active pull rod 27. A frame 36 is fixedly connected to the bottom of the top plate 16. A wedge block 37 is slidably connected inside the frame 36 via a limiting slider. The cross-section of the wedge block 37 is triangular. The other end of the driven pull rod 28 is fixedly connected to one side of the wedge block 37. Three limiting grooves 38 are provided on the top of the wedge block 37. The limiting grooves 38 are parallel to the top inclined surface of the wedge block 37.

[0057] As an example, such as Figures 9-11 As shown, the top of the top plate 16 has three storage slots 29, which are cylindrical. Each of the three storage slots 29 has a suction cup 30, and each of the three suction cups 30 is fixedly connected to a limiting plate 31. The limiting plate 31 is annular and matches the shape of the storage slot 29. The three suction cups 30 are fixed in the storage slots 29 by the limiting plate 31. Each of the three suction cups 30 has an air outlet pipe 32 fixedly connected to its bottom. The bottom end of the air outlet pipe 32 is located above the wedge block 37. Each of the three air outlet pipes 32 has a piston 33 slidably connected to its bottom. Each of the three pistons 33 has an extension rod 34 fixedly connected to its bottom. The bottom ends of the three extension rods 34 pass through the bottom of the three air outlet pipes 32 and are located below the three air outlet pipes 32. Each of the three extension rods 34 has a limiting block 35 fixedly connected to its bottom. The three limiting blocks 35 are slidably engaged in the three limiting slots 38.

[0058] In this embodiment, when the cathode plate is placed on top of the active push plate 8, the upper surface of the suction cup 30 set in the receiving groove 29 on the active push plate 8 is in close contact with the bottom of the cathode plate (the surface that does not need to be polished). After the electric push rod 25 is started, it drives the push frame 26 to move away from the fixed plate 24. The active pull rod 27 and the driven pull rod 28 at the bottom of the push frame 26 are linked and cooperate to pull the wedge block 37 to slide smoothly in the frame 36. As the wedge block 37 moves laterally, the limiting block 35 in the limiting groove 38 at its top is driven by the limiting groove 38, so that the limiting block 35 moves downward along the trajectory of the limiting groove 38. The limiting block 35 pulls down the extension rod 34 connected to it, which drives the piston 33 to move downward in the air outlet pipe 32. The downward movement of the piston 33 causes the cavity inside the suction cup 30 to generate negative pressure, thereby generating a stable adsorption force, which helps to firmly adsorb the bottom of the cathode plate onto the surface of the active push plate 8. This effectively reduces the local warping or vibration of the cathode plate caused by the fluctuation of the grinding force during the polishing process, and ensures that the cathode plate is generally attached and stable.

[0059] When the grinding is complete and the cathode plate needs to be removed, the electric push rod 25 drives the push frame 26 to move in the opposite direction, and synchronously drives the wedge block 37 to slide in the opposite direction within the frame 36. The wedge block 37 pushes the limit block 35 to rise along the limit groove 38 through the limit groove 38, and then lifts the extension rod 34 and the piston 33 to move upward within the air outlet pipe 32. The piston 33 moves upward and re-presses the gas into the cavity of the suction cup 30, quickly breaking the internal negative pressure state, so that the cathode plate can be smoothly separated from the suction cup 30, making it easy for the operator to remove it safely and conveniently.

[0060] As an example, such as Figure 1 and Figure 3 As shown, a motor 10 is fixedly connected to the bottom of the support frame 6. The output shaft of the motor 10 passes through the support frame 6 and is fixedly connected to the drive wheel 11. A rotating shaft 14 is fixedly connected to the bottom of the inner wall of the support frame 6. A driven wheel 15 is rotatably connected to the rotating shaft 14. A belt 12 is sleeved on the drive wheel 11 and the driven wheel 15. A sliding frame 13 is fixedly connected to the bottom of the active push plate 8. The bottom of the sliding frame 13 is fixedly connected to the belt 12.

[0061] As an example, such as Figure 1 As shown, a maintenance door 3 is fixedly connected to the side of the double-sided polishing machine 2 near the support frame 6. A feed inlet 4 is provided on the maintenance door 3. The track 7 is fixedly connected to the support frame 6, and one end extends through the feed inlet 4 into the double-sided polishing machine 2.

[0062] In this embodiment, when the cathode plate needs to be transported to the double-sided polishing machine 2 for grinding, the motor 10 is started to drive the drive wheel 11 at the output shaft end to rotate. Synchronous transmission is achieved through the belt 12, and the driven wheel 15 rotates accordingly, driving the sliding frame 13 and its active push plate 8 to move smoothly along the track 7 towards the double-sided polishing machine 2, so as to stably and accurately feed the cathode plate into the working area of ​​the double-sided polishing machine 2, effectively ensuring the feeding of the cathode plate. After the grinding operation is completed, the motor 10 rotates in the reverse direction, and the active push plate 8 is driven by the belt 12 to move smoothly back along the track 7, automatically removing the processed cathode plate from the double-sided polishing machine 2, and preparing for the next working cycle.

[0063] It should be noted that motor 10 is connected to a power supply and a controller.

[0064] Working principle of this invention:

[0065] During use, the operator places the cathode plate to be ground on top of the active push plate 8 and the auxiliary push plate 9, so that the tabs on both sides of the cathode plate are located between the fixed stop rod 17 and the adjusting stop rod 19, respectively. Then, the electric push rod 25 is activated, which pushes the adjusting stop rod 19 towards the fixed stop rod 17 to achieve longitudinal clamping of the tabs. At the same time, the two adjusting stop rods 19 move towards each other synchronously to apply lateral constraint to the cathode plate, effectively preventing the cathode plate from shifting or deflecting during the grinding process and ensuring the processing position.

[0066] After the cathode plate is placed in place, its bottom is in close contact with the suction cup 30 set on the active push plate 8. While the electric push rod 25 drives the adjusting stop rod 19 to move, it drives the wedge block 37 to slide in the frame 36, and drives the extension rod 34 to press down the piston 33 in the air outlet pipe 32 to draw out the air inside the suction cup 30 and generate negative pressure adsorption. This can reliably fix the bottom of the cathode plate to the surface of the active push plate 8 and the auxiliary push plate 9, effectively suppressing the cathode plate warping caused by uneven force during the polishing process.

[0067] Driven by motor 10, the active push plate 8 moves the cathode plate toward the double-sided polishing machine 2. During the movement, the cathode plate pushes the torsion baffle 53 and the auxiliary push plate 9 forward synchronously until the auxiliary push plate 9 first contacts the support frame 5 and is blocked. At this time, the active push plate 8 continues to move forward under the push of motor 10. The cylinder 39 below the auxiliary push plate 9 slides on the guide rod 43 and stretches the tension spring 41, so that the active push plate 8 and the auxiliary push plate 9 gradually approach each other, and finally send the cathode plate into the processing area of ​​the double-sided polishing machine 2.

[0068] The present invention has the following technical effects.

[0069] 1. The present invention provides overall support for the cathode plate through the active push plate 8 and the auxiliary push plate 9, ensuring that it remains flat during transportation and reducing bending deformation caused by suspension. Through the cylinder 39, tension spring 41, guide rod 43 and adjusting baffle 45, the active push plate 8 and the auxiliary push plate 9 can move closer to each other, thereby smoothly pushing the cathode plate to the grinding station in the double-sided polishing machine 2.

[0070] 2. The present invention, through the support 46, fixing bolt 47, adjusting groove 48 and fixing groove 49, can flexibly adjust the distance between the active push plate 8 and the auxiliary push plate 9 according to the processing requirements of cathode plates of different sizes. Through the support plate 51, fixing rod 54, torsion baffle 53 and torsion spring 55, the distance can be reliably limited, which facilitates the placement and separation of the cathode plate and also facilitates its smooth push into the double-sided polishing machine 2.

[0071] 3. The present invention uses a limiting frame 18, an adjusting stop 19, an arc-shaped push rod 20, and a straight push rod 23 to drive the adjusting stop 19 to move towards the fixed stop 17, thereby clamping the tabs on both sides of the cathode plate and further applying lateral constraints to prevent the cathode plate from shifting during the grinding process. Through the suction cup 30, piston 33, wedge block 37, and limiting groove 38, the bottom of the cathode plate is tightly adsorbed onto the surfaces of the active push plate 8 and the auxiliary push plate 9, ensuring stable adhesion and improving the grinding quality.

[0072] 4. The present invention uses a motor 10, a drive wheel 11, a belt 12 and a driven wheel 15 to drive the active push plate 8 and the auxiliary push plate 9 to move synchronously toward the double-sided polishing machine 2, thereby achieving stable and automatic feeding of the cathode plate and improving the continuity and positioning accuracy of the feeding process.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
