Description

Technical Field

[0001] The invention relates to the technical field of cutting machines, and in particular to a lead-acid battery plate cutting machine. Background Art

[0002] A lead-acid battery is an acidic battery that uses metallic lead as an electrode and manganese dioxide or nickel sulfate as a positive electrode active material. During the battery production process, the plates are usually cast, resulting in certain scraps around the plates, and cutting equipment is needed to repair the plates. For example, patent announcement number CN215091012U discloses a cutting device for bipolar plate processing, comprising a base plate, one side of the base plate is provided with an inclined section, the top of the base plate is fixedly connected to a mounting frame near the inclined section, the top of the mounting frame is fixedly connected to a hydraulic cylinder, the output end of the hydraulic cylinder passes through the mounting frame and is fixedly connected to a connecting plate, a buffer structure is provided between the connecting plate and the mounting frame, the middle end of the bottom of the connecting plate is fixedly connected to a mounting plate, and the two mounting plates are perpendicular to the connecting plate and are symmetrically arranged. The utility model pre-clamps the bipolar plate from the rear end and clamps it at the front end to prevent the bipolar plate from displacement during cutting. At the same time, it cooperates with a stamping and cutting mechanism with a buffer to improve the shearing accuracy of the bipolar plate. The clamping piece slides on the bottom plate to expand the clamping range of the bottom plate, and effectively tightens and cuts bipolar plates of different specifications.

[0003] Existing cutting machines generally cut the edges and corners of the electrode plates in sequence during cutting. Not only do they need to process the four sides continuously during processing, but they also cut the electrode plates independently during processing, resulting in discrepancies in the cut positions of the four sides of the electrode plates, causing deviations in the sizes of multiple electrode plates, which is not conducive to subsequent welding combinations, resulting in problems such as cold welding or loose welding. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By turning the first knob, the rotating rod rotates, the transmission gear rotates, and the transmission gear engages with the teeth, driving the rotating seat to rotate on the connecting plate. When the upper surface of the rotating seat rotates, the matching thread can move with the guide thread, so that the slide seat slides inside the slide groove, and the surrounding slide seats cooperate with the pressing plate to fix the current plate, ensuring the accurate placement of the plate to avoid the problem of deviation in the cutting position caused by the displacement of the plate position, resulting in deviation in the size of the plate, thereby ensuring the stability of the subsequent plate assembly and avoiding the occurrence of cold welding.

[0021] 2. By installing a supporting spring between the pressing plate and the movable groove, the pressing plate can be pushed to fit the electrode plate under the action of the supporting spring, ensuring that the electrode plate is fixed and avoiding the situation where the electrode plate scraps are too large and cannot be fixed. In addition, when the hydraulic rod is started to control the extension column to move downward, the grid positioning block can be aligned with the grid on the electrode plate. The above structure allows the electrode plate to move within a certain range, so that the placement of the electrode plate can be accurately positioned, thereby ensuring the subsequent cutting effect. During cutting, the electrode plate can be fixed by moving the extension column downward to avoid the movement of the electrode plate during cutting.

[0022] 3. The mounting plate can be pressed down by starting the hydraulic rod, and the mounting plate can be rotated by starting the motor, so that the extension column can be moved to the slide bar required for downward cutting, and the slide bar can be docked with the positioning card seat and the positioning hole can be interlaced with the positioning rod to make the driving of the hydraulic rod more stable and avoid air pressure. The motor can be used to switch the downward cutting of the cutting blades on both sides. After completion, the hydraulic rod is reset, and the first reset spring is used to reset the current cutting blade to facilitate the next cutting. The present application can perform synchronous cutting on both sides through a single cutting, thereby reducing the time required for cutting the electrode plate and speeding up the cutting efficiency. In addition, the above structure can ensure that the size of the electrode plate after each cutting is the same, so that there will be no deviation when multiple electrode plates are combined.

[0023] 4. In order to ensure the cutting effect, it is necessary to extend the length of each cutting blade to ensure that the plate scraps can be removed. In order to avoid the vertical and horizontal cutting blades from being blocked during cutting, a sliding plate is slidably installed inside the sliding groove using a second return spring, and then the first guide protrusion and the second guide protrusion are slidably matched, so that the sliding plate can drive the tool holder on the corresponding side to move to a certain position, so that when the horizontal cutting blade cuts downward, the vertical cutting blade can be staggered with the horizontal cutting blade to ensure the cutting effect of the present application.

[0043] The cutting assembly 5 for trimming the electrode plate comprises a support frame 501, the support frame 501 is fixedly mounted on the column body of the mounting column 3, a placement frame 502 is fixedly mounted on one side of the support frame 501, slide rails 503 are respectively mounted on the four sides of the placement frame 502, a slide rod 506 is slidably mounted inside each slide rail 503, and a cutting blade 505 for cutting the electrode plate is connected to one end of the slide rod 506.

[0044] In this embodiment, a movable groove 2032 is opened inside the slide 203, a pressing plate 2034 is slidably installed inside the movable groove 2032, a supporting spring 2033 is fixedly installed between the pressing plate 2034 and the inner wall of the movable groove 2032, and a matching thread 2031 is set at the bottom of the slide 203.

[0045] The operating table 1 has a rotating groove 205 formed inside, a connecting plate 207 is movably mounted on the bottom of the rotating groove 205 through a cylinder 206, a rotating seat 208 is rotatably mounted on the upper surface of the connecting plate 207, a guide thread 2081 is arranged on the upper surface of the rotating seat 208, the guide thread 2081 is threadedly matched with the matching thread 2031, and a tooth 2082 is fixedly mounted on the outer side of the rotating seat 208;

[0046] A rotating rod 204 is rotatably mounted on one side of the placement table 201 , and a transmission gear 2041 and a first knob 2042 are fixedly mounted on both ends of the rotating rod 204 , respectively. The transmission gear 2041 is meshed with the teeth 2082 .

[0047] By turning the first knob 2042, the rotating rod 204 is driven to rotate, the transmission gear 2041 is rotated, and the transmission gear 2041 is meshed with the tooth 2082, driving the rotating seat 208 to rotate on the connecting disk 207. When the upper surface of the rotating seat 208 rotates, the matching thread 2031 can move along with the guide thread 2081, so that the slide 203 slides inside the slide groove 202, and the surrounding slides 203 cooperate with the pressing plate 2034 to fix the current electrode plate, ensuring the accurate placement of the electrode plate to avoid the problem of electrode plate position deviation causing the cutting position to be offset and the electrode size to be deviated, thereby ensuring the stability of the subsequent electrode plate assembly and avoiding the occurrence of cold welding.

[0048] It should be noted that an extension seat 402 is fixedly installed at the output end of the hydraulic rod 401, a motor 403 is fixedly installed inside the extension seat 402, a mounting plate 404 is fixedly installed at the output end of the motor 403, an extension column 4041 is fixedly installed at the lower end of the mounting plate 404, and a grid positioning block 4042 for positioning with the pole plate grid is fixedly installed on the lower surface of the extension column 4041.

[0049] By installing a support spring 2033 between the pressing plate 2034 and the movable groove 2032, the pressing plate 2034 can be pushed to fit the electrode plate under the action of the support spring 2033, ensuring that the electrode plate is fixed and avoiding the situation where the electrode plate scraps are too large and cannot be fixed. In addition, when the hydraulic rod 401 is started to control the extension column 4041 to move downward, the grid positioning block 4042 can be aligned with the grid on the electrode plate. The above structure allows the electrode plate to move within a certain range, so that the placement of the electrode plate can be accurately positioned, thereby ensuring the subsequent cutting effect.

The positioning hole 5061 is inserted and matched with the positioning rod 4044, and the slide rod 506 is connected to the positioning seat 4045.

[0052] By starting the hydraulic rod 401, the mounting plate 404 can be pressed down. By starting the motor 403 to drive the mounting plate 404 to rotate, the extension column 4041 can be moved to the slide bar 506 required for downward cutting. By docking the slide bar 506 with the positioning seat 4045 and interlacing the positioning hole 5061 with the positioning rod 4044, the driving of the hydraulic rod 401 can be more stable to avoid air pressure. The motor 403 can be used to switch the downward cutting of the cutting blades 505 on both sides. After completion, the hydraulic rod 401 is reset, and the first reset spring 5031 is used to reset the current cutting blade 505 to facilitate the next cutting. The present application can perform synchronous cutting on both sides through a single cutting, thereby reducing the time required for cutting the electrode plate and speeding up the cutting efficiency.

[0053] In the present application, a knife holder 504 is fixedly installed on the outside of each slide bar 506, and a cutting blade 505 is fixedly installed inside each knife holder 504, wherein first guide protrusions 5041 are fixedly installed on both ends of the knife holders 504 on both sides, and second guide protrusions 5042 are fixedly installed on both sides of the back of the knife holders 504 on the other two sides, respectively, and the first guide protrusions 5041 and the second guide protrusions 5042 are slidably matched;

[0055] In order to ensure the cutting effect, it is necessary to extend the length of each cutting blade 505 to ensure that the plate scraps can be removed. In order to avoid the vertical and horizontal cutting blades 505 from being blocked during cutting, a sliding plate 5063 is slidably installed inside the sliding groove 5062 using the second return spring 5064, and then the first guide protrusion 5041 and the second guide protrusion 5042 are slidably matched, so that the sliding plate 5063 can drive the tool holder 504 on the corresponding side to move to a certain position, so that when the horizontal cutting blade 505 cuts downward, the vertical cutting blade 505 can be staggered with the horizontal one, thereby ensuring the cutting effect of the present application.

[0056] In the present application, a notch is provided on one side of one of the cutting blades 505 and an extended cutter 5051 is fixedly installed at the notch, an adjustment slot 5052 is provided on the upper side of the extended cutter 5051, an adjustment blade 5055 is slidably installed inside the adjustment slot 5052, a screw rod 5053 is rotatably installed on the upper side of one of the extended cutters 5051, the shaft of the screw rod 5053 is threadedly matched with the adjustment blade 5055, and a second knob 5054 is fixedly installed on one end of the screw rod 5053.

[0057] The screw rod 5053 is driven to rotate by rotating the second knob 5054, and the adjusting blade 5055 is slidably installed inside the adjusting groove 5052, so that the adjusting blade 5055 can be adjusted in position under the threaded cooperation between the screw rod 5053 and the adjusting blade 5055, so that the size of the connecting part of the electrode plate is uniformly fixed, so that multiple electrode plates can be stably welded together when connected later.

[0058] The working principle of this lead-acid battery plate cutting machine:

[0059] When in use, first place the electrode plate on the surface of the placement table 201, then turn the first knob 2042 to drive the rotating rod 204 to rotate, so that the transmission gear 2041 rotates, and the transmission gear 2041 is meshed with the teeth 2082, driving the rotating seat 208 to rotate on the connecting plate 207. When the upper surface of the rotating seat 208 rotates, the matching thread 2031 can move along with the guide thread 2081, so that the slide seat 203 slides inside the slide groove 202, so that the surrounding slide seats 203 cooperate with the pressing plate 2034 to fix the current electrode plate;

[0060] After the fixation is completed, the hydraulic rod 401 is started to control the extension column 4041 to move downward, so that the extension column 4041 moves to the slide bar 506 required for downward pressing and cutting, thereby driving the cutting blades 505 on both sides to press down and cut and reset. After the cutting on both sides is completed, the motor 403 is started to drive the mounting plate 404 to rotate, so that the extension column 4041 is switched to the other two side slide bars 506, and the cutting on the other two sides is carried out;

[0061] After cutting, in order to facilitate personnel to quickly remove the plates, the height of the connecting plate 207 is adjusted by the cylinder 206, so that the guide thread 2081 and the matching thread 2031 are disconnected, thereby releasing the fixation of the surrounding slide seats 203.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
