Description

Technical Field

[0001] The invention relates to the technical field of electrode preparation, in particular to a corrosion-resistant titanium oxide electrode preparation device. Background Art

[0002] Battery refers to a cup, trough or other container or part of a composite container that contains electrolyte solution and metal electrodes to generate electric current. It is a device that can convert chemical energy into electrical energy. It has positive and negative electrodes, including positive and negative electrode sheets. The electrode sheets are usually made of conductive metal sheets. During the processing of the electrode sheets, they need to be stamped and shaped by a stamping device.

The rubber bristles connected to the cleaning roller are used to clean the stamping table. After stamping, there is no need to manually remove the workpiece, which improves the processing efficiency of the battery electrode sheet. Despite this, the existing electrode sheet stamping device still has shortcomings. For example, after the device stamps the electrode sheet, it fails to solve the problem of the smoothness of the edge cut of the stamped electrode sheet, resulting in the stamped electrode sheet cut being too sharp and easily leaving burrs, which poses a risk of scratching the battery tissue in subsequent use.

[0017] As a preferred solution of the present invention, the centers of the punching hole, the punch, the upper chuck and the lower chuck are on the same vertical line.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the blank plate is placed outside the punching hole on the top of the stamping table, and the blank plate is punched by pushing the punch downward through the output rod of the stamping cylinder to obtain an electrode sheet blank. As the stamping cylinder continues to apply downward pressure to the punch, the punch is pushed into the inside of the punching hole, the blank is clamped up and down by the upper clamping part and the lower clamping part, and then the blank is trimmed by the trimming part to improve the smoothness of the edges and corners of the electrode sheet after stamping.

[0020] 2. In the present invention, downward pressure is applied to the punch by the stamping cylinder to push the punch into the inside of the punching hole, and after the punched blank is pressed against the top of the lower chuck, the lower chuck is pushed downward until the bottoms of the two crowbars are in contact with the top of the punching hole. As the punch moves downward, the extrusion crowbars are flipped along the two positioning axes, and the two L-row force plates together with the telescopic rods are pushed downward, so that the upper chuck extends from the bottom of the countersunk hole, and the blank is pushed downward and separated from the bottom of the punch, and the blank is moved down to the trimming component station. At the same time, since the blank is pushed out from the bottom of the punch through the upper chuck, the blank is separated from the punch, which can ensure that the blank is in contact with the trimming component, while avoiding interference caused by direct contact between the punch and the trimming component, thereby improving the service life of the punch.

[0021] 3. In the present invention, the punch is driven by the punching cylinder to push the lower chuck downward, and the lower chuck moves downward, driving the telescopic sleeve to move together, and the telescopic sleeve moves downward to drive the adapter hoop, the two connecting rods and the two sliding pins to move downward. Due to the sliding connection between the sliding pin and the thrust chute, the left and right thrust seats are pushed toward the middle during the downward movement of the sliding pin, and the two trimming seats, the trimming slider and the sandpaper are further moved toward the middle under the connection action of the guide rod. When the punch is pushed by the punching cylinder to move downward to the end position, the inner walls of the two sandpapers just contact the outer edge of the blank, and the servo motor is started. The output shaft of the servo motor drives the active pulley to rotate, and further under the connection action of the power belt The driven pulley and the torsion bar are driven to rotate, and the torsion bar drives the telescopic sleeve together with the lower chuck to rotate, and the blank is further driven to rotate under the upper and lower clamping action of the lower and upper chucks on the blank, and rubs against the two sandpapers to trim the blank. At the same time, the lower chuck drives the rotating cam to rotate, thereby alternately shifting the front and rear L-shaped levers, so that the front and rear two escapement pendulum bars swing back and forth around the two locating pins, and under the sliding connection between the bar groove and the pendulum pin and the connection action of the trimming slider, the two trimming sliders are pushed to swing up and down along the two arc-shaped slide grooves, thereby chamfering and trimming the top and bottom edges of the blank, further improving the smoothness of the edge of the blank.

[0022] 4. In the present invention, after the stamping and trimming is completed, the punch is driven to reset upward by the stamping cylinder, and the second reset spring is elastically released, pushing the lower clamp and the torsion bar to reset upward, driving the adapter hoop, the two connecting rods and the two sliding pins to move upward. Due to the sliding connection between the sliding pin and the thrust bevel, the left and right thrust seats are pushed to both sides during the upward movement of the sliding pin, so that the sandpaper is separated from the trimmed electrode sheet, which can ensure that the electrode sheet will not contact the two sandpapers again during the process of the lower clamp driving the electrode sheet to move upward, thereby avoiding damage to the electrode sheet and ensuring the quality of the stamping and trimming of the electrode sheet.

[0037] Specifically, the present embodiment places a blank plate on the periphery of the punching hole 102 on the top of the stamping table 101, and pushes the punch 3 downward by the output rod of the stamping cylinder 2 to move and stamp the blank plate to obtain an electrode sheet blank. As the stamping cylinder 2 continues to apply downward pressure to the punch 3, the punch 3 is pushed into the inside of the punching hole 102, and the blank is clamped up and down by the upper clamping component and the lower clamping component, and then the blank is trimmed by the trimming component to improve the smoothness of the edges and corners of the electrode sheet after stamping.

[0038] Embodiment 2:

[0039] The upper clamping component includes a telescopic rod 401 slidably mounted inside the telescopic circular hole 302, an upper chuck 402 is fixedly mounted at the bottom of the telescopic rod 401, and the upper chuck 402 is located inside the countersunk hole 303, L-row force plates 403 are fixedly mounted on the upper left and right walls of the telescopic rod 401, and a limiting groove 405 is provided at one end of the L-row force plate 403 away from the telescopic rod 401, and two L-row force plates 403 are respectively located inside the two thrust grooves 301, and a positioning shaft 406 is fixedly mounted between the front wall and the rear wall of the two thrust grooves 301, and a crowbar 407 is rotatably mounted on the outer wall of the positioning shaft 406, and one end of the crowbar 407 close to the L-row force plate 403 abuts against the inside of the limiting groove 405;

[0040] The lower clamping component includes a U-shaped positioning frame 501 fixedly installed at the bottom of the punching machine 1, the U-shaped positioning frame 501 is located at the bottom of the punching hole 102, a telescopic sleeve 502 is slidably installed at the bottom of the U-shaped positioning frame 501, and a lower clamp 503 is fixedly installed on the top of the telescopic sleeve 502. The centers of the punching hole 102, the punch 3, the upper clamp 402 and the lower clamp 503 are on the same vertical line;

[0041] Specifically, the present embodiment applies downward pressure to the punch 3 through the stamping cylinder 2, pushes the punch 3 into the interior of the punching hole 102, and after the punched blank is pressed against the top of the lower clamp 503, pushes the lower clamp 503 downward until the bottom of the two crowbars 407 contacts the top of the punching hole 102, as the punch 3 moves downward, the extrusion crowbar 407 flips along the two positioning axes 406, pushes the two L-row force plates 403 together with the telescopic rod 401 downward, so that the upper clamp 402 extends from the bottom of the countersunk hole 303, pushes the blank downward and separates it from the bottom of the punch 3, moves the blank down to the trimming component station, and at the same time, because the blank is pushed out from the bottom of the punch 3 through the upper clamp 402, the blank is separated from the punch 3, which can ensure that the blank contacts the trimming component, while avoiding direct contact and interference between the punch 3 and the trimming component, thereby improving the service life of the punch 3.

[0042] Furthermore, a first return spring 404 is fixedly installed at the bottom of the L-row force plate 403, and the bottom of the first return spring 404 is fixedly installed to the bottom wall of the thrust groove 301. When the L-row force plate 403 moves downward, it causes a compression effect on the first return spring 404, causing the first return spring 404 to generate elastic force and store energy. When the stamping is completed, the stamping cylinder 2 drives the punch 3 to move upward, and the two crowbars 407 are separated from the top of the stamping machine 1. The first return spring 404 is elastically released, pushing the L-row force plate 403, the telescopic rod 401 and the upper clamp 402 to move upward and reset, waiting for the next stamping.

[0043] Furthermore, a plurality of key slots 5002 with equal angles are provided on the inner wall of the telescopic sleeve 502, a torsion bar 506 is slidably installed inside the telescopic sleeve 502, a plurality of key blocks 5006 with equal angles are fixedly installed on the outer wall of the torsion bar 506, the outer wall of the key block 5006 is slidably connected to the inner wall of the key slot 5002, and by setting the sliding connection between the key slot 5002 and the key block 5006, a torque limiting effect can be performed between the telescopic sleeve 502 and the torsion bar 506 while ensuring the sliding telescopicity between the telescopic sleeve 502 and the torsion bar 506, so that the torsion bar 506 can further drive the telescopic sleeve 502 to rotate, thereby realizing the transmission of torque.

[0044] Furthermore, a driven pulley 507 is fixedly installed at the bottom of the torsion bar 506, a servo motor 508 is fixedly installed on the bottom wall of the stamping table 101, and a driving pulley 509 is fixedly installed on the outer wall of the servo motor 508. A power belt 5010 is commonly connected between the driving pulley 509 and the driven pulley 507. The driving pulley 509 is driven to rotate by the output shaft of the servo motor 508, and the driven pulley 507 and the torsion bar 506 are further driven to rotate under the connection action of the power belt 5010. The torsion bar 506 drives the telescopic sleeve 502 to rotate together with the lower chuck 503, and further drives the blank to rotate under the upper and lower clamping action of the lower chuck 503 and the upper chuck 402 on the blank, so that the blank and the trimming parts rub to smooth the edges and corners after stamping.

[0045] Furthermore, an adapter ring 504 is rotatably installed on the upper part of the outer wall of the telescopic sleeve 502, and a second return spring 505 is fixedly installed on the bottom of the adapter ring 504. The bottom of the second return spring 505 is fixedly connected to the bottom wall of the U-shaped positioning frame 501. By setting the adapter ring 504 and the torsion bar 506 for conversion, the torsion bar 506 cannot drive the second return spring 505 to rotate. After the stamping cylinder 2 drives the punch 3 to cause the lower clamp 503 to move downward, the torsion bar 506 moves downward along the U-shaped positioning frame 501 and gradually slides to the outside of the torsion bar 506. During this period, the second return spring 505 is continuously compressed and energy is stored. After the stamping is completed, the stamping cylinder 2 drives the punch 3 to move upward, and the second return spring 505 is elastically released, pushing the lower clamp 503 and the torsion bar 506 to reset upward to facilitate the next stamping.

[0046] Embodiment three:

[0047] The trimming component includes two guide seats 601 distributed on the left and right, two guide rods 602 distributed up and down are slidably installed inside the two guide seats 601, the inner ends of the two guide rods 602 are commonly connected to a trimming seat 603, an arc-shaped slide groove 604 is provided on the inner side of the trimming seat 603, and a trimming slider 6010 is slidably installed inside the two arc-shaped slide grooves 604. Positioning pins 6011 are fixedly installed on the front wall and the rear wall of the U-shaped positioning frame 501, and an escapement pendulum bar 6014 is rotatably installed on the outer wall of the positioning pin 6011. The middle of the escapement pendulum bar 6014 An L-shaped lever 6012 is fixedly installed at the bottom, a rotating cam 6019 is fixedly installed at the bottom of the lower clamp 503, and the rotating cam 6019 corresponds to the position of the L-shaped lever 6012. Both ends of the escapement swing bar 6014 are provided with a strip groove 6015. The front and back sides of the trimming slider 6010 are fixedly installed with a coupling plate 6016. The side away from the two coupling plates 6016 is fixedly installed with a swing pin 6017. The position of the swing pin 6017 corresponds to the position of the strip groove 6015. The swing pin 6017 is slidably connected inside the strip groove 6015.

[0048] The two guide rods 602 are connected to a thrust seat 605 at one end away from the trimming seat 603. A thrust inclined slot 606 is provided through the front of the thrust seat 605. A transfer collar 607 is rotatably installed at the lower part of the outer wall of the telescopic sleeve 502. A connecting rod 608 is fixedly installed on the left and right walls of the transfer collar 607. A sliding pin 609 is fixedly installed at one end of the connecting rod 608 away from the transfer collar 607. The sliding pin 609 is slidably located inside the thrust inclined slot 606.

[0049] Specifically, the punch 3 is driven by the stamping cylinder 2 to push the lower chuck 503 downward, and the telescopic sleeve 502 is moved together with the lower chuck 503 during the downward movement. The telescopic sleeve 502 moves downward and drives the adapter hoop 607, the two connecting rods 608 and the two sliding pins 609 to move downward. Due to the sliding connection between the sliding pin 609 and the thrust chute 606, the sliding pin 609 pushes the left and right thrust seats 605 toward the middle during the downward movement, and further moves the two trimming seats 603, the trimming slider 6010 and the sandpaper 6018 toward the middle under the connection action of the guide rod 602. When the stamping cylinder 2 pushes the punch 3 to move downward to the end position, the inner walls of the two sandpapers 6018 just contact the outer edge of the blank, and the servo motor 508 is started. The output shaft of the servo motor 508 drives the active pulley 509 to rotate, and further at the connection of the power belt 5010 Under the action, the driven pulley 507 and the torsion bar 506 are driven to rotate, and the torsion bar 506 drives the telescopic sleeve 502 together with the lower clamp 503 to rotate, and further drives the blank to rotate under the upper and lower clamping action of the lower clamp 503 and the upper clamp 402 on the blank, and rubs with the two sandpapers 6018 to trim the blank. At the same time, the lower clamp 503 drives the cam 6019 to rotate, thereby alternately shifting the front and rear L-shaped levers 6012, so that the front and rear escapement pendulum bars 6014 swing back and forth around the two positioning pins 6011, and under the sliding connection between the bar groove 6015 and the pendulum pin 6017 and the connection action of the trimming slider 6010, the two trimming sliders 6010 are pushed to swing up and down along the two arc-shaped slide grooves 604, thereby chamfering and trimming the top and bottom edges of the blank, further improving the smoothness of the edge of the blank.

[0050] It should be noted that after the stamping and trimming is completed, the punch 3 is driven to reset upward by the stamping cylinder 2, and the second reset spring 505 is elastically released, pushing the lower clamp 503 and the torsion bar 506 to reset upward, driving the adapter hoop 607, the two connecting rods 608 and the two sliding pins 609 to move upward. Due to the sliding connection between the sliding pin 609 and the thrust bevel 606, the sliding pin 609 pushes the left and right thrust seats 605 to both sides during the upward movement of the sliding pin 609, so that the sandpaper 6018 is separated from the trimmed electrode sheet, which can ensure that during the process of the lower clamp 503 driving the electrode sheet to move upward, the electrode sheet will not contact the two sandpapers 6018 again, avoiding damage to the electrode sheet and ensuring the quality of the stamping and trimming of the electrode sheet.

[0051] Furthermore, the periphery of the positioning pin 6011 is sleeved with a torsion spring 6013, which is fixedly installed between the U-shaped positioning frame 501 and the escapement pendulum 6014. When the escapement pendulum 6014 is flipped over, the torsion spring 6013 is compressed and stores energy, so that after the stamping is completed, the escapement pendulum 6014 is driven to rotate and reset by the rebound force of the torsion spring 6013 to facilitate the next use.

[0052] Furthermore, the inner side of the trimming slider 6010 is bonded with sandpaper 6018 via Velcro. By bonding the sandpaper 6018 and the trimming slider 6010 via Velcro, the worn sandpaper 6018 can be easily replaced at a later time, thereby improving the convenience of use.

[0053] When the corrosion-resistant titanium oxide electrode preparation device of the present scheme is working, the blank plate is placed on the periphery of the punching hole 102 on the top of the punching table 101, and the punch 3 is pushed downward by the output rod of the punching cylinder 2 to move and punch the blank plate to obtain an electrode sheet blank. As the punching cylinder 2 continues to apply downward pressure to the punch 3, the punch 3 is pushed into the inside of the punching hole 102, and after the punched blank is pressed against the top of the lower clamp 503, the lower clamp 503 is pushed downward until the bottom of the two crowbars 407 contacts the top of the punching hole 102. As the punch 3 moves downward, the extrusion crowbar 407 is flipped along the two positioning axes 406, and the two L-shaped force plates 403 are pushed downward together with the telescopic rod 401, so that the upper clamp 402 extends from the bottom of the countersunk hole 303, and the blank is pushed downward and separated from the bottom of the punch 3. When the blank moves down to the middle of the two sandpapers 6018, the stamping cylinder 2 stops.

[0054] During the downward movement of the lower chuck 503, the telescopic sleeve 502 is driven to move together. The downward movement of the telescopic sleeve 502 drives the adapter hoop 607, the two connecting rods 608 and the two sliding pins 609 to move downward. Due to the sliding connection between the sliding pin 609 and the thrust chute 606, the sliding pin 609 pushes the left and right thrust seats 605 toward the middle during the downward movement, and further moves the two trimming seats 603 together with the trimming slider 6010 toward the middle under the connection action of the guide rod 602. When the stamping cylinder 2 pushes the punch 3 downward to the terminal position, the inner walls of the two sandpapers 6018 just contact the outer edge of the blank, and the servo motor 508 is started. The output shaft of the servo motor 508 drives the active pulley 509 to rotate, and further drives the driven pulley 507 and the torsion bar 506 under the connection action of the power belt 5010. The torsion bar 506 rotates, and the telescopic sleeve 502 rotates together with the lower clamp 503, and further drives the blank to rotate under the upper and lower clamping action of the lower clamp 503 and the upper clamp 402 on the blank, rubs against the two sandpapers 6018, and trims the blank. At the same time, the lower clamp 503 drives the rotating cam 6019 to rotate, thereby alternately shifting the front and rear two L-shaped levers 6012, so that the front and rear two escapement pendulum bars 6014 swing back and forth around the two positioning pins 6011, and under the sliding connection action of the bar groove 6015 and the pendulum pin 6017 and the connection action of the trimming slider 6010, the two trimming sliders 6010 are pushed to swing up and down along the two arc-shaped slide grooves 604, thereby chamfering and trimming the top and bottom edges of the blank, further improving the smoothness of the edge of the blank.
