Description

Technical Field

[0001] This invention belongs to the field of battery electrode processing technology, and in particular relates to a slitting machine. Background Technology

[0002] A slitting machine is a mechanical device that can longitudinally cut strips into strips of several required specifications. It can be used in the slitting and processing of battery electrodes. Battery electrodes are usually required during battery processing, and the quality of the battery electrodes affects the quality and service life of the battery.

[0003] When existing slitting machines slit lithium battery electrodes, the slit electrodes are pulled to the winding mechanism for winding. The winding rollers on these machines are usually separate, detachable units mounted on the main body. A pressing mechanism then compresses the slit strips of battery electrodes onto the rotating winding roller. Once the winding roller has wound a sufficient amount of electrode strips, the operator must manually remove it from the main body and install a new one. This process not only reduces the continuous slitting efficiency of the slitting machine but also requires frequent manual removal and installation of the winding roller to ensure continuous and efficient slitting, thus affecting the overall slitting efficiency of the lithium battery electrodes.

There is an arc-shaped block, and the outer side of the arc-shaped block is in contact with the outer ring of the locking post that is engaged in the U-shaped mounting groove. The side of the arc-shaped block corresponding to the bottom of the groove is connected to one end of the support spring. The other end of the support spring is fixed to the bottom of the shrinkage groove. An elastic hose is inserted into the support spring, and the two ends of the elastic hose are respectively sealed and connected to the arc-shaped block and the bottom of the shrinkage groove. Each arc-shaped guide groove is provided with a fitting limit component, which is used to fit and limit the locking post that is engaged in the U-shaped mounting groove.

[0006] Preferably, the fitting and limiting component includes an elastic cavity strip and an elastic retaining strip. Each arc-shaped guide groove is provided with an elastic cavity strip, and one end face of the elastic cavity strip is connected to the bottom of the arc-shaped guide groove, while the other end face is connected to an elastic retaining strip. The elastic retaining strip is slidably inserted into the arc-shaped guide groove. The tail ends of the elastic retaining strips slidably disposed in the two arc-shaped guide grooves are fitted with the outer ring surface of the engaging post inserted into the U-shaped mounting groove. The elastic cavity strip is connected to the elastic flexible tube through a flow guide groove, and the four sides of the elastic cavity strip are slidably fitted with the four sides of the arc-shaped guide groove. A control valve is provided in the flow guide groove.

[0007] Preferably, a contact groove is provided at the part where the locking post fits with the arc-shaped block and the elastic locking strip, and a metal block is insulated and installed in the contact groove. An electromagnet block is insulated and installed on the surface where the arc-shaped block and the elastic locking strip fit with the locking post, and the electromagnet block fits correspondingly with the metal block.

[0008] Preferably, a support block is sleeved on the connecting shaft on the inner side of the symmetrical take-up reel via a bearing. An electric push rod is fixedly installed on the lower surface of each of the symmetrical support blocks. An arc-shaped push block is installed on the piston rod end face of the electric push rod. The arc-shaped push block, which slides up and down on the inner side of the take-up reel, slides and contacts the positioning ring on the inner side.

[0009] Preferably, the pressing mechanism includes a support shaft, a support frame, a shaft sleeve, a rotating shaft, and pressing rollers. The support shaft is rotatably mounted on the main body and is located above the take-up reel. Multiple support frames are equidistantly and obliquely fixed on the support shaft. Each support frame is fixed with a shaft sleeve, and the center holes of the multiple shaft sleeves are located on the same horizontal line.

The two ends of the take-up rollers can be detachably limited and fixed in the U-shaped mounting slots by the set fastening limiting components. This allows multiple take-up rollers to be rotatably installed at the take-up mechanism of the main body, thereby enabling the slitting machine to continuously cut the battery electrode sheets into strips and store them. This eliminates the need to frequently replace the take-up roller installed on the front of the main body, allowing the slitting machine to continuously slit and wind the battery electrode sheets, thus improving the efficiency of the slitting machine in cutting battery electrode sheets.

[0014] 2. This invention, by setting a snap-fit ​​limiting component in the U-shaped mounting groove, and cooperating with the arc-shaped block and the elastic locking strips symmetrically extending from the outer side of the snap-fit ​​column, can limit and fix the snap-fit ​​column in the U-shaped mounting groove. The positioning rings on both ends of the snap-fit ​​column can play an axial limiting role in snapping into the take-up roller, thereby preventing the take-up roller from axially shifting or jumping in the U-shaped mounting groove when it is installed on the take-up reel to take up the slit battery electrode sheets.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-6As shown, the present invention is a slitting machine, including a main body 1, on which an unwinding mechanism, a traction mechanism and a slitting mechanism are sequentially arranged; a winding mechanism 2 is arranged on the front side of the main body 1, and a pressing mechanism 7 is arranged above the winding mechanism 2. The winding mechanism 2 includes a winding reel 21, and the symmetrical winding reels 21 are respectively rotatably arranged on the main body 1, and the winding reels 21 are connected to each other by a connecting shaft 22. Multiple U-shaped mounting grooves 211 are arranged in a circumferential array on the symmetrical winding reels 21. A winding roller 23 is detachably installed in each U-shaped mounting groove 211 by means of a fastening limiting component 3. A winding sleeve 24 is installed at equal intervals on each winding roller 23.

[0026] In the design scheme of this invention, two take-up reels 21 are symmetrically rotated on the main body 1, and the two take-up reels 21 are connected by a connecting shaft 22. When the slitting machine needs to work to slit the battery electrode sheets, the operator can use a robotic arm to insert the two ends of the take-up roller 23 into the U-shaped mounting grooves 211 opened on the two take-up reels 21. Then, the take-up roller 23 is locked and fixed by the fastening and limiting component 3 set in the U-shaped mounting groove 211. Then, the take-up reels 21 are continuously driven to rotate by the servo motor fixed on the main body 1, so that the installed take-up roller 23 rotates clockwise. Then, new take-up rollers 23 are continuously installed in the empty U-shaped grooves. Inside the mounting slot 211, when the take-up reel 21 drives the mounted take-up roller 23 to rotate below the pressing mechanism 7, the traction mechanism assists in fixing the slit battery electrode sheets onto the take-up sleeves 24 fixed at equal intervals on the take-up roller 23. Then, other servo motors fixed on the main body 1 drive the corresponding take-up roller 23 to rotate on the take-up reel 21, thereby facilitating the winding of the slit battery electrode sheets. When the take-up roller 23 has wound up a sufficient number of slit battery electrode sheets, the existing cutting mechanism or slitting mechanism is controlled to cut multiple battery electrode sheets from the taking-up sleeves 24. Then, the servo motor is disengaged from the take-up roller 23, and the pressing mechanism 7 is controlled to move from above the take-up roller 23. The oscillation disengages the take-up reel 21, causing it to continue rotating clockwise and rotate the take-up roller 23, which is wrapped with the strip-shaped battery electrode sheet, downwards. Meanwhile, the unused take-up roller 23 mounted on the take-up reel 21 rotates to below the pressing mechanism 7. At this point, the take-up reel 21 stops rotating, and the cut strip-shaped electrode sheet is then attached to the take-up sleeve 24. A new take-up roller 23 rotates on the take-up reel 21 to continue winding the slit battery electrode sheet. When the take-up reel 21 drives the wound take-up roller 23 to its lowest position, the locking and limiting assembly 3 disengages from the locking and securing assembly of the take-up roller 23 fixed in the U-shaped mounting groove 211, thus winding the take-up roller 23 with the electrode sheet. 3 will detach from the take-up reel 21, and the detached take-up roller 23 can be clamped and transferred out by a robotic arm or auxiliary machine. When the take-up reel 21 rotates and rotates the empty U-shaped mounting groove 211 to the outer side of the main body 1, the new take-up roller 23 is inserted and locked into the U-shaped mounting groove 211. This allows the slitting machine to continuously cut the battery electrode sheets into strips and store them. As a result, there is no need to frequently replace the take-up roller 23 installed separately on the front of the main body 1, so that the slitting machine can continuously slit and rewind the battery electrode sheets. The two sets of take-up mechanisms 2 set on the front of the main body 1 will not interfere with each other.

[0027] In one embodiment of the present invention, the fastening and limiting assembly 3 includes a locking post 31, a positioning ring 32, an arc-shaped block 33, a support spring 34, an elastic hose 35, and a fitting and limiting assembly. The two ends of the take-up roller 23 are respectively rotatably mounted with locking posts 31 via bearings, and each locking post 31 is slidably engaged into a U-shaped mounting groove 211. Positioning rings 32 are installed on both ends of each locking post 31, and the two positioning rings 32 are slidably attached to the two sides of the take-up reel 21. The bottom of the U-shaped mounting groove 211 has a shrinkage groove 213, and the two side walls of the groove have arc-shaped guide grooves 212. Each U-shaped mounting groove 211... Each arc-shaped block 33 is slidably arranged inside the U-shaped mounting groove 211, and the outer side of the arc-shaped block 33 is in contact with the outer ring surface of the locking post 31 that is engaged in the U-shaped mounting groove 211. The side of the arc-shaped block 33 corresponding to the bottom of the groove is connected to one end face of the support spring 34. The other end face of the support spring 34 is fixed to the bottom of the shrinkage groove 213. An elastic hose 35 is inserted into the support spring 34, and the two ends of the elastic hose 35 are respectively sealed and connected to the arc-shaped block 33 and the bottom of the shrinkage groove 213. Each arc-shaped guide groove 212 is provided with a fitting limiting component, which is used to fit and limit the locking post 31 that is engaged in the U-shaped mounting groove 211.

[0028] In the design of this invention, when the two ends of the clamped take-up roller 23 approach the opening of the U-shaped mounting groove 211, the locking pins 31 on the take-up roller 23 will slide into the U-shaped mounting groove 211, and the positioning rings 32 at both ends of the locking pins 31 will fit against the two openings of the U-shaped mounting groove 211, thereby limiting the axial direction of the take-up roller. When the locking pins 31 slide towards the bottom of the U-shaped mounting groove 211, the locking pins 31 will squeeze the arc-shaped block 33, causing the arc-shaped block 33 to move towards the bottom of the groove. At this time, the support spring 34 will be compressed, and the elastic hose 35 will also be compressed. The fluid filled in the elastic hose 35 will enter the fitting limit installed in the arc-shaped guide grooves 212 opened on the upper and lower walls of the U-shaped mounting groove 211. Inside the mounting assembly, the bonding limiting assembly will adhere to the outer side of the locking post 31, thereby facilitating the locking post 31 to be fixed in the U-shaped mounting groove 211. This prevents the strip electrode sheet wrapped around the take-up roller 23 from being pulled too far, causing the take-up roller 23 to detach from the U-shaped mounting groove 211. When the take-up reel 21 rotates the take-up roller 23 with the strip electrode sheet to directly below the take-up reel 21, the bonding limiting assembly is controlled to disengage from the front side of the locking post 31. Then, the elastic restoring force of the support spring 34 will push the locking post 31 to detach from the U-shaped mounting groove 211, thereby facilitating the automatic detachment of the detached take-up roller 23 from the take-up reel 21. Then, the robotic arm clamps and transfers the detached take-up roller 23 for storage.

[0029] In one embodiment of the present invention, the fitting and limiting component includes an elastic cavity strip 36 and an elastic retaining strip 37. Each arc-shaped guide groove 212 is provided with an elastic cavity strip 36, and one end face of the elastic cavity strip 36 is connected to the bottom of the arc-shaped guide groove 212, and the other end face is connected to the elastic retaining strip 37. The elastic retaining strip 37 is slidably inserted into the arc-shaped guide groove 212. The tail ends of the elastic retaining strips 37 slidably disposed in the two arc-shaped guide grooves 212 are fitted with the outer ring surface of the engaging post 31 inserted into the U-shaped mounting groove 211. The elastic cavity strip 36 is connected to the elastic hose 35 through the flow guide groove 214, and the four sides of the elastic cavity strip 36 are slidably fitted with the four sides of the arc-shaped guide groove 212 respectively. A control valve is provided in the flow guide groove 214.

[0030] In the design of this invention, when the locking post 31 slides into the U-shaped mounting groove 211, when the middle part of the locking post 31 passes the opening of the arc-shaped guide groove 212, the ring surface of the locking post 31 continuously presses the arc-shaped block 33 towards the bottom of the U-shaped mounting groove 211. At this time, the flowing liquid in the elastic hose 35 will enter the elastic cavity strip 36 through the guide groove 214. The Cishousi control valve is in the open state, and the continuous flow of flowing liquid into the elastic cavity strip 36 will cause it to extend along its length in the arc-shaped guide groove 212. At this time, the spring in the elastic cavity strip 36 will be stretched, which will push the free end of the elastic locking strip 37 to extend from the arc-shaped guide groove 212 and approach the front side of the locking post 31. This facilitates the upper and lower symmetrical elastic locking strips 37 to limit and fix the locking post 31 in the U-shaped mounting groove 211. After the locking post 31 is limited and installed in the U-shaped mounting groove 211, this... When the control valve in the flow guide groove 214 is closed, the flowing liquid in the elastic cavity strip 36 will not flow back into the elastic hose 35, and the elastic hose 35 can then pull the compressed support spring 34. When the take-up reel 21 drives the take-up roller 23 with the electrode sheet to rotate directly downwards, the control valve opens, and the elastic restoring force of the spring in the elastic cavity strip 36 will pull the elastic cavity strip 36 to retract into the arc-shaped guide groove 212. At this time, the elastic locking strip 37 will retract into the arc-shaped guide groove 212, and the flowing liquid will enter the elastic hose 35, causing the elastic hose 35 to expand and stretch. At this time, the elastic thrust of the support spring 34 will push the arc-shaped block 33 towards the opening of the U-shaped mounting groove 211, so that the locking pins 31 at both ends of the take-up roller 23 can quickly move out of the U-shaped mounting groove 211, thus facilitating the automatic disassembly and detachment of the take-up roller 23 from the take-up reel 21.

[0031] In one embodiment of the present invention, a contact groove 311 is provided at the part where the locking post 31 is in contact with the arc-shaped block 33 and the elastic locking strip 37, and a metal block 39 is insulatedly installed in the contact groove 311. An electromagnet block 38 is insulatedly installed on the surface where the arc-shaped block 33 and the elastic locking strip 37 are in contact with the locking post 31, and the electromagnet block 38 is correspondingly in contact with the metal block 39.

[0032] In the design of this invention, to prevent the locking post 31 from pressing the arc-shaped block 33 too deeply, which would prevent the extended elastic strip 37 from fitting tightly against the locking post 31, when the elastic strip 37 extends from the arc-shaped guide groove 212 and approaches the outer side of the locking post 31, the electromagnet block 38 on the arc-shaped block 33 and the elastic strip 37 is energized. This allows the electromagnet block 38 to have magnetic attraction force and adhere to the outer side of the metal block 39. Consequently, the symmetrical elastic strip 37 and arc-shaped block 33 can adhere to and wrap around the locking post 31, further limiting and fixing the locking post 31 within the U-shaped mounting groove 211, preventing the winding drum from jumping within the U-shaped mounting groove 211 when rotating to wind up the battery electrode. This phenomenon affects the precise winding of the slit battery electrode sheets by the take-up drum. When the take-up drum needs to be disengaged from the U-shaped mounting groove 211, the electromagnet block 38 is de-energized to demagnetize it, so that the elastic clip 37 only contacts the locking post 31. Then, under the elastic push of the support spring 34, the locking post 31 will move towards the opening of the U-shaped mounting groove 211. At this time, the elastic cavity strip 36 is pulled into the arc-shaped guide groove 212 by the spring, which will drive the elastic clip 37 of the elastic material to retract into the arc-shaped guide groove 212. This makes it easier for the locking post 31 to disengage and be fixed from the U-shaped mounting groove 211, and thus makes it easier to quickly pick up and transfer the wound take-up roller 23 from below the take-up reel 21.

[0033] As one embodiment of the present invention, a support block 4 is sleeved on the connecting shaft 22 on the inner side of the symmetrical take-up reel 21 through a bearing. An electric push rod 5 is fixedly installed on the lower surface of each of the symmetrical support blocks 4. An arc-shaped push block 6 is installed on the piston rod end face of the electric push rod 5. The arc-shaped push block 6, which slides up and down on the inner side of the take-up reel 21, slides and contacts the positioning ring 32 on the inner side.

[0034] In the design of this invention, to prevent excessive resistance in the engagement of the locking post 31 within the U-shaped mounting groove 211, which would prevent the counterforce of the support spring 34 from disengaging the locking post 31 from the U-shaped mounting groove 211, when the take-up reel 21 drives the completed take-up roller 23 to rotate downwards, the piston rod of the electric push rod 5 fixed on the inner side support block 4 of the symmetrical take-up reel 21 extends, causing it to drive the arc-shaped push block 6 towards the inner side positioning ring 32. Then, under the push of the telescopic rod, the arc-shaped push block 6 generates a downward thrust on the positioning ring 32, thereby... The locking post 31 is stably pushed out of the U-shaped mounting groove 211 for disassembly. After the take-up roller 23 is disengaged from the U-shaped mounting groove 211, the piston rod of the electric push rod 5 is retracted, causing it to drive the arc-shaped push block 6 to slide upward. This facilitates the take-up reel 21 to drive the take-up roller 23 to continue rotating downward for disassembly. Since the support block 4 is rotatably connected to the connecting shaft 22 through a bearing, the rotation of the connecting shaft 22 will not drive the electric push rod 5 to rotate. This allows the arc-shaped push block 6 to always face downward to push the take-up roller 23, which has rotated to the downward position, to disengage.

[0035] In one embodiment of the present invention, the pressing mechanism 7 includes a support shaft 71, a support frame 72, a shaft sleeve 73, a rotating shaft 74, and pressing rollers 75. The support shaft 71 is rotatably mounted on the main body 1 and is located above the take-up reel 21. Multiple support frames 72 are equidistantly and obliquely fixed on the support shaft 71. Each support frame 72 is fixed with a shaft sleeve 73, and the center holes of the multiple shaft sleeves 73 are located on the same horizontal line. A rotating shaft 74 is inserted into the multiple shaft sleeves 73. Multiple pressing rollers 75 are rotatably mounted on the rotating shaft 74 at equal intervals. Each pressing roller 75 is in rolling contact with and aligned with each take-up sleeve 24.

[0036] In the design of this invention, when the take-up roller 23 continuously drives the take-up sleeve 24 to take up the slit electrode sheets, the support shaft 71 is slowly rotated by other servo motors fixed on the main body 1. This allows the distance between the multiple pressure rollers 75 and the take-up sleeve 24 to be adjusted through the support frame 72, shaft sleeve 73, and rotating shaft 74, ensuring that the pressure rollers 75 are always pressed tightly against the battery electrode sheets being taken up. When the take-up reel 21 needs to drive the take-up roller 23 to rotate, the support shaft 71 drives the support frame 72 to swing at a large angle, causing the multiple pressure rollers 75 to disengage from the surface of the battery electrode sheets after winding, without affecting the normal rotation of the take-up roller 23 driven by the take-up reel 21. When the take-up reel 21 drives the take-up roller 23 to rotate below the strip-shaped battery electrode sheets, the support shaft 71 is controlled to rotate, causing it to drive the multiple pressure rollers 75 to swing to the take-up sleeve 24 through the support frame 72, thus facilitating the continued winding of the slit strip-shaped battery electrode sheets.

[0037] In one embodiment of the present invention, the support shaft 71 is connected to two fixed seats 76 near the outer ring surface of the main body 1 by bearing sleeves, and each fixed seat 76 is fixedly connected to the inner side surface of the main body 1. Each fixed seat 76 is fixedly installed with an electric push rod 5. The piston rod end face of the electric push rod 5 is equipped with an elastic sealing plug 77. The symmetrical elastic sealing plugs 77 slide and squeeze into the U-shaped mounting groove 211.

[0038] In the design of this invention, when the take-up reel 21 drives the new take-up roller 23 to rotate below the pressing mechanism 7, the piston rods of the electric push rods 5 fixed at both ends of the control support shaft 71 through the fixed seat 76 extend, so that they push the elastic sealing plugs 77 fixed at the end face of the piston rods to elastically squeeze and insert into the corresponding U-shaped mounting groove 211, thereby enabling the elastic sealing plugs 77 to further lock into the U-shaped mounting groove 211 and play a limiting and fixing role in the take-up roller 23; when the take-up roller 23 finishes winding, it is necessary to control the piston rods of the electric push rods 5 on the fixed seat 76 to retract, so that they drive the elastic sealing plugs 77 to disengage from the corresponding U-shaped mounting groove 211, thereby facilitating the take-up reel 21 to drive the wound strip battery electrode sheet to rotate directly downwards for disassembly and disassembly.

[0039] As one embodiment of the present invention, a square insertion hole 231 is provided on one end face of the take-up roller 23, and a square rod 8 is slidably inserted into the square insertion hole 231. The outer end face of the square rod 8 is connected to the piston rod end face of the electric push rod 5, and the fixed section of the electric push rod 5 is connected to the output shaft of the servo motor fixed on the main body 1.

[0040] In the design of this invention, when the take-up reel 21 drives the take-up roller 23 to rotate below the pressure mechanism 7, the piston rod of the electric push rod 5 fixed on the output shaft of the servo motor on the main body 1 will extend, causing the square rod 8 to be inserted into the square insertion hole 231 opened on the end face of the aligned take-up roller 23. This facilitates the take-up roller 23 to rotate between the two take-up reels 21 to take up the strip-shaped battery electrode sheets. When the take-up roller 23 has taken up a sufficient amount of battery electrode sheets, and the take-up reel 21 needs to drive the take-up roller 23 to rotate downward, the piston rod of the electric push rod 5 fixed on the output shaft of the servo motor needs to be retracted first, causing the square rod 8 to disengage from the square insertion hole 231. This facilitates the take-up reel 21 to drive the take-up roller 23 to rotate downward to the bottom for disassembly and disassembly.
