Description

Technical Field

[0001] This application relates to the field of battery cap production equipment technology, and in particular to a conveying device for battery cap production. Background Technology

[0002] The lithium battery cap is one of the core safety components of a lithium battery. Its main functions are to seal the battery, prevent electrolyte leakage, and integrate safety structures such as overcurrent protection (e.g., PTC) and overvoltage protection (e.g., explosion-proof valve). Its production process includes basic component processing, safety element assembly, sealing integration, and performance testing. The basic component processing mainly includes the cap shell forming stage and the conductive component forming stage. In the cap shell forming stage, aluminum strip coils need to be punched through a multi-station stamping machine to complete the following steps in sequence: punching (cutting into round blanks), stretching (forming the cover groove to accommodate the safety element), and punching (punching conductive holes for the lower cover and explosion-proof holes for the upper cover).

[0003] Currently, the production process of lithium battery caps typically uses a punching machine to punch the aluminum strip coil. For example, the utility model with publication number CN212822043U discloses a slicing device for processing lithium battery caps. This slicing device includes a feeding mechanism, a slicing mechanism, and a waste recycling mechanism. The feeding mechanism includes a first drive motor, a first upper drive wheel, and a first lower drive wheel. When the slicing device is working, the aluminum sheet required for processing the lithium battery cap is first passed between the first upper drive wheel and the second lower drive wheel. At this time, the first drive motor drives the first upper drive wheel to rotate, which in turn drives the aluminum sheet to move and transport the aluminum sheet to the slicing mechanism. Then, the slicing mechanism punches the aluminum sheet.

[0004] Because rolling oil is used during the rolling process of aluminum strip coils, oil stains will form on the surface of the aluminum strip. However, when the feeding mechanism of the slicing device for lithium battery cap processing is working, it directly transports the aluminum strip coil to the slicing mechanism for punching. The rolling oil on the surface of the aluminum strip coil easily mixes with residual aluminum powder and dust from rolling to form an abrasive. During punching, these mixtures will repeatedly rub against the die edge and the aluminum strip, accelerating the wear of the cutting edge and thus affecting the service life of the die. Furthermore, in the subsequent welding process of lithium battery cap production, the smoke generated by the burning of oil stains can cause porosity and incomplete welding in the weld, affecting the welding quality. Utility Model Content

[0005] The purpose of this application is to provide a conveying device for battery cap production, which solves the problem in the related art where the feeding mechanism of the slicing device for lithium battery cap processing directly conveys the aluminum strip coil to the slicing mechanism for punching, which easily affects the service life of the mold and the welding quality.

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below.

[0018] This application discloses a conveying device for producing battery caps.

[0019] A conveying device for producing battery caps includes a frame 10, a cleaning component 20, a transfer mechanism 30, a replacement component 40, an unwinding mechanism 60, a winding mechanism 70, and a roller 80.

[0020] Reference Figures 1 to 3 An unwinding mechanism 60 is mounted on the frame 10 and is used to mount and release the aluminum strip coil 90. More specifically, the unwinding mechanism 60 includes an unwinding reel 61 and an unwinding motor 62. The unwinding reel 61 is rotatably mounted on the frame 10, and the unwinding motor 62 is fixedly mounted on the frame 10 and is used to drive the unwinding reel 61 to rotate. An idler roller 80 is rotatably mounted on the frame 10 and is used to wind and support the aluminum strip coil 90 released by the unwinding mechanism 60. A winding mechanism 70 is mounted on the frame 10 and is used to wind the aluminum strip coil 90 that has passed over the idler roller 80. More specifically, the winding mechanism 70 includes a winding reel 71 and a winding motor 72. The winding reel 71 is rotatably mounted on the frame 10, and the winding motor 72 is fixedly mounted on the frame 10 and is used to drive the winding reel 71 to rotate.

[0021] During the punching production of the battery cap, the aluminum strip coil 90 is wound onto the unwinding reel 61, then the aluminum strip coil 90 is wrapped around the idler roller 80 and connected to the take-up reel 71, and the aluminum strip coil 90 passes through the punching mechanism 50 required for punching the aluminum strip coil 90. In related technologies, the punching mechanism 50 can adopt the following structure: the punching mechanism 50 includes a worktable 51, an upper die holder 52, a lower die holder 53, a pressure plate 54, and a compression spring 55. The upper die holder 52 is slidably mounted vertically on the worktable 51. More specifically, the worktable 51 is provided with a guide post 511, and the upper die holder 52 is slidably sleeved on the outside of the guide post 511. The worktable 51 is equipped with a punching drive for driving the upper die holder 52 to move vertically back and forth. The punching drive can be a hydraulic cylinder module 56. A support plate 512 is provided on the guide column 511. The hydraulic cylinder module 56 is fixed on the support plate 512. The upper die holder 52 is fixedly connected to the piston rod of the hydraulic cylinder module 56.

[0022] The upper die holder 52 has a punch 521 at its bottom, and the lower die holder 53 is fixed on the worktable 51. The lower die holder 53 has a die hole 531 corresponding to the punch 521. The pressure plate 54 has a connecting rod 541, which slides through the upper die holder 52. The connecting rod 541 has a flange 542 for limiting the separation of the connecting rod 541 from the upper die holder 52. A compression spring 55 is sleeved on the outside of the connecting rod 541, and the two ends of the compression spring 55 abut against the pressure plate 54 and the upper die holder 52, respectively. The pressure plate 54 has a through hole 543, through which the punch 521 passes. The worktable 51 has a pair of limiting posts 513 with a spacing adapted to the width of the aluminum strip coil 90. The upper die holder 52 has clearance holes 522 corresponding to the limiting posts 513.

[0023] At the start of the punching process, the aluminum strip coil 90 rests against the upper surface of the lower die base 53. Then, the upper die base 52 is driven downwards along the guide post 511 by the hydraulic cylinder module 56. During this downward movement, the pressure plate 54 first contacts the aluminum strip coil 90, pressing it firmly. Next, the compression spring 55 is compressed, and the punch 521 moves downwards and inserts into the die hole 531 to punch the aluminum strip coil 90. The upper die base 52 is then reset, and the winding motor 72 drives the winding reel 71 to rotate, winding the aluminum strip coil 90. Simultaneously, the unwinding motor 62 drives the unwinding reel 61 to rotate, unwinding the aluminum strip coil 90, allowing it to be conveyed forward a certain distance. The punching process is then repeated, and the above steps are executed again.

[0024] Reference Figures 4 to 9 The replacement assembly 40 includes a replacement chamber 41 fixed to the frame 10. Multiple cleaning assemblies 20 are provided and can be detachably placed within the replacement chamber 41. The transfer mechanism 30 can be detachably connected to the cleaning assemblies 20 located within the replacement chamber 41 via a locking mechanism, and moves the cleaning assemblies 20 from the replacement chamber 41 to contact the upper and lower sides of the aluminum strip coil 90 wound on the idler roller 80. Thus, when the aluminum strip coil 90 is conveyed by the winding mechanism 70 and the unwinding mechanism 60, the cleaning assemblies 20 are located on the upper and lower sides of the aluminum strip coil 90 and remain in contact with the upper and lower sides of the aluminum strip coil 90. The cleaning assemblies 20, in contact with the upper and lower sides of the aluminum strip coil 90, wipe and clean the aluminum strip coil 90, thereby achieving a certain cleaning effect on the oil stains adhering to the surface of the aluminum strip coil 90. After a period of use, the cleaning effectiveness of the cleaning assembly 20 decreases. At this time, the cleaning assembly 20 is detached from the transfer mechanism 30 via the locking mechanism. The transfer mechanism 30 is then connected to the unused cleaning component 20 located in the exchange chamber 41, and the cleaning component 20 is moved out of the exchange chamber 41 to contact the upper and lower sides of the aluminum strip coil 90 to clean the aluminum strip coil 90. This continuously provides a good cleaning effect on the aluminum strip coil 90, extends the service life of the punching mechanism 50, and reduces the impact on the welding quality in the subsequent production process of the lithium battery cap.

[0025] In an optional embodiment, the transfer mechanism 30 has the following specific structure: The transfer mechanism 30 includes a horizontal moving module, a vertical moving module, a tilting seat 35, and a base 36. The horizontal moving module is mounted on the frame 10. The vertical moving module is connected to the horizontal moving movable end of the horizontal moving module. The horizontal moving module can be a horizontal moving linear screw module 31, and the horizontal moving movable end of the horizontal moving module is the horizontal moving slide 32 of the horizontal moving linear screw module 31. The tilting seat 35 is rotatably mounted on the vertical moving movable end of the vertical moving module. The vertical moving module can be a vertical moving linear screw module 33, and the vertical moving movable end of the vertical moving module is the vertical moving slide 34 of the vertical moving linear screw module 33. The tilting seat 35 is rotatably connected to the vertical moving slide 34 of the vertical moving linear screw module 33 via a pivot 351. The vertical moving end of the vertical moving module is provided with a flipping drive for driving the flipping seat 35 to rotate. The flipping drive can be a flipping drive motor 38. The flipping drive motor 38 is fixed on the vertical moving slide 34 of the vertical moving linear screw module 33. The output shaft of the flipping drive motor 38 is connected to the pivot 351.

[0026] The base 36 is connected to the flip seat 35 via a buffer spring 37. More specifically, the base 36 is provided with a connecting post 361, which slides through the flip seat 35. The connecting post 361 is provided with a protruding plate 362 for limiting the separation of the connecting post 361 and the flip seat 35. The buffer spring 37 is sleeved on the outside of the connecting post 361, and the two ends of the buffer spring 37 abut against the base 36 and the flip seat 35 respectively.

[0027] The cleaning component 20 is detachably connected to the base 36 via a locking mechanism. In an optional embodiment, the structure of the cleaning component 20 and the locking mechanism, and the connection relationship between the cleaning component 20, the locking mechanism, and the transfer mechanism 30 are as follows: The cleaning component 20 includes a cleaning seat 21 and a cleaning block 22 fixedly connected to the cleaning seat 21. The cleaning block 22 may be a sponge block. The locking mechanism includes a locking block 39 and a locking spring 310. The base 36 is provided with a groove 363. The cleaning seat 21 is provided with a boss 211 that can engage with the groove 363. The side of the boss 211 is provided with a locking groove 212. The base 36 is provided with a guide groove 364. The locking block 39 is slidably disposed in the guide groove 364 on the base 36. The locking block 39 is provided with a wedge-shaped block 391 that can engage with the locking groove 212. The locking block 39 has a frame-shaped structure, and the wedge-shaped block 391 is disposed on the inner side wall of the frame-shaped locking block 39.

[0028] One end of the locking block 39 is provided with a column 392, and the other end of the locking block 39 is provided with an unlocking column 393. The locking spring 310 is sleeved on the outside of the column 392. The two ends of the locking spring 310 abut against the inner wall of the locking block 39 and the guide groove 364 respectively. The locking spring 310 is used to push the locking block 39 to slide in the direction where the wedge block 391 engages with the locking groove 212. The frame 10 is provided with a baffle 11 that can abut against the end of the unlocking column 393 away from the locking block 39.

[0029] After the cleaning seat 21 engages with the groove 363 via the boss 211, the wedge block 391 engages with the locking groove 212 under the elastic force of the locking spring 310. At this time, the cleaning assembly 20 is fixedly connected to the transfer mechanism 30. When it is necessary to separate the cleaning assembly 20 from the transfer mechanism 30, when the cleaning assembly 20 is in a vertically downward state, the transfer mechanism 30 drives the base 36 to move until the unlocking post 393 abuts against the baffle 11, and causes the unlocking post 393 to retract relative to the base 36, thereby causing the locking block 39 to slide, so that the wedge block 391 separates from the locking groove 212. Then, under the action of gravity, the cleaning assembly 20 falls off and can be disassembled and separated from the transfer mechanism 30.

[0030] In an optional embodiment, the cleaning component 20 can be placed in the replacement chamber 41 by a limiting mechanism to prevent the cleaning component 20 from falling out of the replacement chamber 41. Simultaneously, the replacement component 40 can be provided with a push plate 42 and a push spring 43 within the replacement chamber 41. The push plate 42 is driven by the elastic force of the push spring 43 to push the cleaning component 20, so that multiple cleaning components 20 are tightly arranged within the replacement chamber 41. The specific structure of the limiting mechanism, and the connection relationship between the push plate 42, the push spring 43, and the replacement chamber 41, are as follows: The limiting mechanism includes a limiting block 25 and a linkage component. The limiting block 25 is retractably mounted on the cleaning seat 21. Limiting grooves 411 are provided on both side walls of the replacement chamber 41. The cleaning components 20 located within the replacement chamber 41 are slidably engaged with the limiting block 25 and the limiting grooves 411, thereby preventing the cleaning component 20 from falling out of the replacement chamber 41.

[0031] A linkage component is mounted on the cleaning seat 21 and connected to the limiting block 25. When the boss 211 engages with the groove 363, it acts on the linkage component and drives the limiting block 25 to retract relative to the cleaning seat 21, causing the limiting block 25 to exit from the limiting groove 411, thereby removing the cleaning component 20 from the replacement chamber 41. More specifically, the linkage component includes a linkage column 26 and an extension spring 27. The linkage column 26 is telescopically slidably mounted on the cleaning seat 21 and has a protrusion 261. The cleaning seat 21 has a sliding groove 213 for avoiding the protrusion 261. The extension spring 27 is sleeved on the outside of the linkage column 26, with both ends of the extension spring 27 abutting against the end face of the protrusion 261 and the end face of the sliding groove 213, respectively. The extension spring 27 is used to push the linkage column 26 to extend relative to the boss 211. The linkage column 26 is connected to the limiting block 25. Furthermore, the protrusion 261 is provided with a pin 262, the limiting block 25 is provided with a plate 251, and the plate 251 is provided with a groove 252, through which the pin 262 passes. When the linkage column 26 retracts relative to the cleaning seat 21, it can drive the limiting block 25 to retract relative to the cleaning seat 21.

[0032] The push plate 42 is slidably disposed in the replacement chamber 41. The two sides of the push plate 42 are provided with sliders 421 that are slidably locked in the limiting grooves 411. The push spring 43 acts on the push plate 42 and is used to drive the push plate 42 to push the cleaning component 20. More specifically, the push plate 42 is provided with a slide rod 422 that slides through the wall of the replacement chamber 41. The push spring 43 is sleeved on the outside of the slide rod 422. The two ends of the push spring 43 abut against the push plate 42 and the wall of the replacement chamber 41, respectively.

[0033] The implementation principle of the conveying device for battery cap production in this embodiment is as follows: When the aluminum strip coil 90 is conveyed by the winding mechanism 70 and the unwinding mechanism 60, the cleaning component 20 is located on the upper and lower sides of the aluminum strip coil 90, and the cleaning block 22 is in contact with the upper and lower sides of the aluminum strip coil 90, wiping and cleaning the aluminum strip coil 90 through the cleaning block 22. After the cleaning block 22 has been used for a period of time, its cleaning effectiveness decreases. At this time, the unused cleaning component 20 in the replacement chamber 41 is replaced by the transfer mechanism 30 to maintain the cleaning effect. The specific replacement steps are as follows: The rotating base 35 is driven to rotate by the rotating drive motor 38, which flips the cleaning component 20 so that the cleaning block 22 faces down. Then, the base 36 is raised and lowered by the vertical linear screw module 33 until the unlocking post 393 is level with the baffle 11. Then, the base 36 is moved laterally by the horizontal linear screw module 31, so that the unlocking post 393 abuts against the baffle 11 and slides relative to the base 36, thereby pushing the wedge block 391 out of the locking groove 212. Then, the cleaning component 20 falls off under the action of gravity and is disassembled from the base 36. Next, the position of the base 36 is adjusted by the vertical linear screw module 33 and the horizontal linear screw module 31. Then, the flipping drive motor 38 drives the flipping seat 35 to rotate until the groove 363 of the base 36 faces the cleaning component 20 in the replacement chamber 41. Then, the vertical linear screw module 33 drives the base 36 to move towards the replacement chamber 41, so that the base 36 engages with the boss 211 through the groove 363. At the same time, the wedge block 391 engages with the locking groove 212, fixing the base 36 and the cleaning seat 21 in place. After the base 36 engages with the boss 211 through the groove 363, the linkage column 26 is pushed to retract relative to the cleaning seat 21. Then, the pin 262 pushes the inclined groove 252, causing the limiting block 25 to retract relative to the cleaning seat 21 and exit from the limiting groove 411, allowing the cleaning component 20 to be removed from the replacement chamber 41. Next, the cleaning component 20 is transferred by the vertical linear screw module 33, the horizontal linear screw module 31 and the flip drive motor 38, so that the replaced cleaning component 20 contacts the upper and lower sides of the aluminum strip roll 90 through the cleaning block 22, thereby continuously achieving a good cleaning effect on the aluminum strip roll 90.
