Description

Technical Field

[0001] The present invention relates to the technical field of cylindrical battery sealing, and in particular to a cylindrical battery sealing processing device and a use method thereof. Background Art

[0002] Cylindrical battery is a common battery form, and its sealing technology is a key link to ensure the normal operation and safety of the battery. Cylindrical battery sealing technology is designed to effectively seal the inside of the battery to ensure that the internal positive electrode, negative electrode, electrolyte and other substances are not interfered with and leaked from the outside world, thereby ensuring the performance and life of the battery.

[0003] The prior art, such as a cylindrical lithium-ion battery disclosed in the announcement number CN214957083U, includes a shell and a battery cell unit contained in the shell. The shell is composed of a tubular cylinder, a positive electrode cover plate and a negative electrode cover plate at both ends. The periphery of the positive electrode cover plate is coated with a positive electrode sealing ring, and the periphery of the negative electrode cover plate is coated with a negative electrode sealing ring. The two ends of the cylinder are respectively coated on the positive electrode sealing ring and the negative electrode sealing ring by mechanical rolling to form the battery shell. At the same time, the existing technology, such as the steel shell cylindrical battery sealing machine device disclosed in the announcement number CN215834567U, includes a mold frame, a pressing plate driven by a lifting mechanism is arranged on the mold frame, a pair of modules are slidably connected on the bottom plate of the mold frame, and a positioning structure for clamping the steel shell cylindrical battery after the pair of modules move towards each other is arranged on the module, and a linkage structure is arranged on the pressing plate to cooperate with the module to realize the pair of modules moving towards each other when the pressing plate moves downward. However, the above technology still has problems in use due to structural limitations: In the prior art, the sealing operation of cylindrical batteries is usually completed by secondary mold stamping. However, after the first sealing operation, the machine needs to be stopped to disassemble and replace the mold, which undoubtedly reduces the working rate of the cylindrical battery sealing operation. In addition, when sealing a cylindrical battery that needs to be sealed at both ends as disclosed in CN214957083U, both ends of the cylindrical battery are first grooved, and then the two ends of the cylindrical battery are sealed. However, the prior art lacks components for sealing the two ends of the cylindrical battery in sequence, so that the secondary sealing operation can only be completed on one end of the cylindrical battery, and then the cylindrical battery is disassembled and the sealing processing position is changed before the secondary sealing operation can be performed on the other end, which further reduces the working rate of the sealing operation at both ends of the cylindrical battery.

When the first sealing mold 19 is used, the two ends of the battery base shell 2 are electrically The battery base shell 2 is bent at the center of the circle, and when the second sealing mold 20 is used, the two ends of the battery base shell 2 are flattened and are in close contact with a group of cap plates 4 respectively to complete the sealing operation. At the same time, since the sealing mold is a mature technical means in the field to which the present application belongs, it is not described in detail. A sealing hydraulic cylinder 21 fixedly connected to the mobile base block 9 is fixedly installed in the first guide groove 8. The mobile base block 9 is provided with a clamping drive mechanism, and it is used to drive two groups of clamping semicircular arc plates 13 to clamp the two rolling grooves 3 of the battery base shell 2 respectively, as shown in the attached Fig.13 As shown, when the two limiting arc plates 12 move downward, the two limiting arc plates 12 are away from the two rolling grooves 3, and the two groups of clamping semi-arc plates 13 are moved relatively close to clamp the two rolling grooves 3, and when the two limiting arc plates 12 move upward, the two groups of clamping semi-arc plates 13 are moved away from each other in the opposite direction to release the clamping of the two rolling grooves 3. At the same time, the two limiting arc plates 12 are respectively located below the two rolling grooves 3, and the positions of the two rolling grooves 3 are limited again. A conversion drive mechanism is provided in the body 1 and the cavity, and it is used to rotate the two first sealing molds 19 or the two second sealing molds 20 by 90 degrees to align with the clamped battery base shell 2, so that the two first sealing molds 19 and the two second sealing molds 20 perform the first sealing and the second sealing on a group of cap plates 4 of the battery base shell 2 in turn, thereby completing the sealing operation at both ends of the battery base shell 2.

[0018] Preferably, as attached Figure 5 As shown, the clamping drive mechanism includes a vertical through groove 22 opened in the movable base block 9, a vertical movable block 23 is provided in a sliding sleeve in the vertical through groove 22, a lifting cylinder 24 is fixedly installed at the lower end of the semicircular placement plate 10, and the output end of the lifting cylinder 24 is fixedly connected to the vertical movable block 23, and the vertical movable block 23 is allowed to move vertically and linearly through the limiting of the lifting cylinder 24 and the vertical through groove 22, and the left and right ends of the movable base block 9 are respectively integrally formed with inclined long rods 25 fixedly connected to the mounting platform 11, so that the two mounting platforms 11 are located at the same height, and the two inclined long rods 25 are both provided with inclined limit grooves 26.

[0019] Preferably, the clamping drive mechanism also includes two connecting long rods 27 respectively fixedly connected to the left and right ends of the vertical moving block 23, the two connecting long rods 27 are respectively slidably sleeved in the two inclined limit grooves 26, and the two connecting long rods 27 are respectively fixedly connected to the lower ends of the two limit arc plates 12, a mounting platform 11 is provided with a sliding through groove 28 at the middle end, the two limit arc plates 12 are respectively slidably sleeved in the two sliding through grooves 28, a mounting platform 11 is provided with clamping guide grooves 29 at both upper and lower ends, and the two clamping guide grooves 29 of a mounting platform 11 are a group, and a group of clamping semi-circular arc plates 13 are respectively slidably sleeved in a group of clamping guide grooves 29; the clamping drive mechanism also includes two rotating connecting rods 30 respectively pin-mounted at the upper and lower ends of a limit arc plate 12, and the other ends of the two rotating connecting rods 30 are respectively pin-connected to a group of clamping semi-circular arc plates 13, as shown in the attached Figure 5 and attached Fig.13 As shown, when the limiting arc plate 12 moves downward, the limiting arc plate 12 drives the rotating connecting rod 30 to move downward, and deflects the rotating connecting rod 30 in the vertical direction. At the same time, through the limiting of the clamping guide groove 29, the two clamping semi-circular arc plates 13 are relatively moved closer. When the limiting arc plate 12 moves upward, the limiting arc plate 12 drives the rotating connecting rod 30 to move upward, and deflects the rotating connecting rod 30 in the horizontal direction, so that the two clamping semi-circular arc plates 13 move away from each other in the opposite direction. The upper and lower ends of the moving base block 9 are provided with vertical guide grooves 46, and the upper and lower ends of the vertical moving block 23 are Both are fixedly connected with a pushing and telescopic rod 31 which is slidably connected to the vertical guide groove 46, and the two pushing and telescopic rods 31 are respectively slidably sleeved in the two horizontal through grooves 43, and the lower ends of the two pushing and telescopic rods 31 are fixedly installed with friction long blocks 32. The left and right ends of the movable base block 9 are provided with locking holes 33. A locking cylinder can be arranged at the locking hole 33 of the movable base block 9, and the output end of the locking cylinder can be sleeved in the locking hole 33. When the two groups of clamping semi-circular arc plates 13 are clamped or released, the output end of the locking cylinder can be extended and moved, and abutted against the vertical movable block 23 to lock the two groups of clamping semi-circular arc plates 13.

[0020] Preferably, the conversion drive mechanism includes a driving motor 34 fixedly installed in the cavity, and the output end of the driving motor 34 is fixedly connected to a rotating shaft 35, and a driving gear 36 is keyed on the rotating shaft 35. The driving motor 34 drives the rotating shaft 35 and the driving gear 36 to rotate. Two transverse long grooves 45 are provided on the inner wall of the cavity, and the two transverse long grooves 45 are both slidably sleeved with moving racks 37. The transverse long grooves 45 are used to move the moving racks 37 laterally. Since the two moving racks 37 are respectively meshed and connected with the upper and lower ends of the driving gear 36, when the driving gear 36 rotates, the two moving racks 37 move relatively close to each other or move away from each other in the opposite direction. The two moving racks 37 are respectively fixedly connected to the lower ends of the two mounting base blocks 16.

[0021] It is particularly noted that when both ends of the battery base shell 2 enter the first sealing mold 19 or the second sealing mold 20, the battery base shell 2 is allowed to remain in the first sealing mold 19 or the second sealing mold 20, and the sealing operation time of both ends of the battery base shell 2 is increased to maintain the shape of the two ends of the battery base shell 2 after the sealing operation. Fig.11 and attached Fig.12 As shown, the push telescopic rod 31 is started, and the output end of the push telescopic rod 31 is moved downward from the highest point of the push telescopic rod 31, so that the friction block 32 is against the rotating shaft 35, and the pressure of the friction block 32 on the rotating shaft 35 can be increased according to the downward movement of the output end of the push telescopic rod 31, and the friction between the friction block 32 and the rotating shaft 35 is increased to prevent the rotating shaft 35 from rotating freely at this time. If the first sealing mold 19 and the second sealing mold 20 rotate during the sealing operation, the movement seriously affects the sealing quality of the battery base shell 2. After completing the first or second sealing operation, the push telescopic rod 31 is moved upward to move away from the rotating shaft 35, and then the battery base shell 2 is taken away from the first sealing mold 19 and the second sealing mold 20; and when the push telescopic rod 31 is located at the lowermost end of the vertical guide groove 46, if the output end of the push telescopic rod 31 is located at the highest point of the push telescopic rod 31, the friction block 32 does not contact the rotating shaft 35; Preferably, the conversion drive mechanism further includes two conversion gears 38 respectively connected to the lower ends of the two rotating shafts 17 by keys, and the left and right ends of the machine body 1 are fixedly connected to fixed racks 39 meshing with the conversion gears 38. When the mounting base 16 moves, since the fixed racks 39 are fixedly arranged, the fixed racks 39 provide a reverse thrust to the conversion gears 38 to allow the conversion gears 38 to rotate. Fig. 9 and attached Fig.10 As shown, the lower ends of the two rotating shafts 17 are fixedly connected to a rotating long plate 40, and a first limit block 41 and a second limit block 42 are fixedly installed on the upper end of a mounting base block 16, and the first limit block 41 and the second limit block 42 are arranged at 90 degrees. After the first sealing mold 19 is aligned with the battery base shell 2, the rotating long plate 40 abuts against the first limit block 41 to prevent the rotating shaft 17 from continuing to rotate toward the first limit block 41, and after the second sealing mold 20 is aligned with the battery base shell 2, the rotating long plate 40 and the second limit block 42 movably abut against each other to prevent the rotating shaft 17 from continuing to rotate toward the second limit block 42.

[0022] It is particularly noted that before the first sealing operation and the second sealing operation are performed, the movable base block 9 is first positioned at the middle end of the first guide groove 8, and then the movable base block 9 is driven to move to perform the first sealing operation and the second sealing operation; Figure 1 and attached Fig.11As shown, when the first sealing mold 19 is aligned with the battery base shell 2, the first sealing mold 19 is located at the outermost end of the second guide groove 44, and when the second sealing mold 20 is aligned with the battery base shell 2, the second sealing mold 20 is located at the middle end of the second guide groove 44. At the same time, after the battery base shell 2 completes the first sealing operation, the two ends of the battery base shell 2 are bent to reduce the overall length, so that the overall length of the battery base shell 2 that has not been sealed is longer than the overall length of the battery base shell 2 that has completed the first sealing operation. Therefore, through the position difference between the aligned first sealing mold 19 and the aligned second sealing mold 20, the distance between the to-be-sealed position of the battery base shell 2 that has not been sealed and the first sealing mold 19 is the same as the distance between the to-be-sealed position of the battery base shell 2 that has completed the first sealing operation and the second sealing mold 20, and then the secondary sealing operation is completed under the same conditions to control the quality after sealing.

[0023] The present invention can be explained by the following operation mode: First, place the middle end of the battery base shell 2 on the semicircular arc placement plate 10, and then place the two first arc bars 14 into the two rolling grooves 3 of the battery base shell 2 respectively to perform preliminary positioning of the battery base shell 2. Figure 1 As shown, at this time, the two first sealing molds 19 are aligned with the battery base shell 2, and the lifting cylinder 24 is started, so that the lifting cylinder 24 drives the vertical moving block 23 to move downward in the vertical through groove 22, as shown in the attached Fig.13 and attached Fig.14 As shown, the vertical moving block 23 drives the two limiting arc plates 12 to move downward together through the two connecting long rods 27, so that the two first arc strips 14 are away from the two rolling grooves 3, and the one limiting arc plate 12 drives the two rotating connecting rods 30 to move downward, so that the two rotating connecting rods 30 are deflected in the vertical direction, thereby driving the two clamping semi-arc plates 13 to move relatively close, and at the same time, the two second arc strips 15 are placed in a rolling groove 3, so that the two groups of clamping semi-arc plates 13 clamp and limit the two rolling grooves 3 of the battery base shell 2; Start the sealing hydraulic cylinder 21 afterwards, as shown in the attached Figure 1 As shown, the sealing hydraulic cylinder 21 drives the movable base block 9 to move in the first guide groove 8 toward the first sealing mold 19 at the left end, until the left end of the battery base shell 2 enters the first sealing mold 19 at the left end, so as to perform the first sealing operation on the left end of the battery base shell 2, so that the left end of the battery base shell 2 is bent toward the center of the battery base shell 2, and then the right end of the battery base shell 2 is moved toward the first sealing mold 19 at the right end by the sealing hydraulic cylinder 21, until the right end of the battery base shell 2 enters the first sealing mold 19 at the right end, so as to perform the first sealing operation on the right end of the battery base shell 2, so that the right end of the battery base shell 2 is bent toward the center of the battery base shell 2; When both ends of the battery base shell 2 have completed the first sealing operation, the movable base block 9 is moved to the middle end of the first guide groove 8, and then the driving motor 34 is started to drive the rotating shaft 35 to rotate. Fig.11 and attached Fig.12 As shown, the rotating shaft 35 drives the driving gear 36 to rotate clockwise, and at the same time, the driving gear 36 meshes with the two moving racks 37 to make the two moving racks 37 move relatively close to each other, and the two moving racks 37 drive the two mounting base blocks 16 to move relatively close to each other, and because the conversion gear 38 meshes with the fixed rack 39 to drive, and the fixed rack 39 is fixedly arranged, the fixed rack 39 provides a reverse thrust to the conversion gear 38, so that the left end conversion gear 38 rotates counterclockwise, and the left end conversion gear 38 drives the L-shaped rotating rod 18 to rotate counterclockwise through the left end rotating shaft 17, so that the left end second sealing mold 20 is aligned with the battery base shell 2, and the right end conversion gear 38 rotates clockwise, so that the right end second sealing mold 20 is aligned with the battery base shell 2; Restart the sealing hydraulic cylinder 21, as shown in the attached Fig.11 As shown, the sealing hydraulic cylinder 21 drives the movable base block 9 to move toward the second sealing mold 20 at the left end until the left end of the battery base shell 2 enters into the second sealing mold 20 at the left end, so as to perform a second sealing operation on the left end of the battery base shell 2, so that the left end of the battery base shell 2 is flattened and in close contact with the positive electrode cap plate, and then the right end of the battery base shell 2 is moved toward the second sealing mold 20 at the right end until the right end of the battery base shell 2 enters into the second sealing mold 20 at the right end, so as to perform a second sealing operation on the right end of the battery base shell 2, so that the right end of the battery base shell 2 is flattened and in close contact with the negative electrode cap plate, thereby completing the sealing operation at both ends of the battery base shell 2.
