Description

Technical Field

[0001] The invention relates to the technical field of lithium battery cell processing, and in particular to a lithium battery cell production slicing device and method. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. Lithium battery cells are composed of multiple layers of lithium battery chips. Lithium battery cells need to go through a process during production - slicing.

[0003] The traditional lithium battery cell slitting process usually relies on manual operation or semi-automatic equipment, resulting in low efficiency, large errors in manual operation, and cumbersome operation process, which is prone to human errors. In the traditional slitting process, the installation and adjustment of the slitting blades often rely on manual labor, making it difficult to ensure the accuracy and consistency of each slitting. In addition, the positioning and pushing of materials may also lead to deviations in the slitting process. The traditional slitting process often has resistance and unsmoothness when transferring materials between different links, resulting in material retention, accumulation or delay. The slitting equipment is often large in size, complex in structure, and occupies a large space. The transmission between different equipment may require multiple independent workstations, which increases the floor space and operating costs. Summary of the invention

[0020] Preferably, a cutting method of a lithium battery cell cutting device capable of automatically replacing a lithium battery cell comprises the following steps:

[0021] S1: Material input and preparation

[0022] The lithium battery material is placed in the feeding frame of the linkage feeding mechanism and arranged longitudinally along the frame. The bottom layer of the material is placed on the material placement table and aligned between the guide rail wall 1 and the guide rail wall 2. The belt transmission part starts to operate, driving the linkage rod and the traction rod, and pushing the material to the working bearing table through the slider 1 and the slider 2, ready for slitting.

[0023] S2: Slitting process

[0024] When the material reaches the work platform, the push grid and the rear push frame push the material to the slitting blade to complete the slitting process of the lithium battery cell. The belt transmission member drives the linkage rod to make the push grid and the rear push frame return. At this time, the slitting lithium battery cell is pushed into the cutting area.

[0025] S3: Material pushing and discharging

[0026] The pusher grid continues to push the lithium battery material to the outside of the operating platform and contacts the lever of the linkage discharge mechanism. The lever pushes the arc-shaped contact rod, which in turn rotates the wheel, thereby opening the opening and closing plate on the operating platform, and the cut lithium battery material slides out smoothly and is unloaded;

[0027] S4: System reset and preparation for next round of operations

[0028] After completing the cutting and unloading of the material, the lever and the push frame continue to return, and return to the top of the material placement table through the belt transmission and the traction rod. Slide block 1 and slide block 2 slide along the trapezoidal limiting groove, triggering the reverse guide mechanism to ensure that the system returns to the starting position and prepares for the next round of material processing.

[0029] The present invention provides a lithium battery cell production slicing device, which has the following beneficial effects:

[0030] 1. The present invention has an efficient automated process: the system automatically completes the slitting, pushing, and discharging of lithium batteries through the cooperation of a series of linkage mechanisms, greatly reducing the need for manual operation. Various parts such as the static slitting mechanism, linkage feeding mechanism, operating carrier, linkage discharging mechanism, etc., work closely with each other to ensure efficient material processing. The static slitting mechanism accurately slits lithium batteries by stacking multiple groups of slitting blades in an equidistant manner. Since the contact between the slitting blades and the lithium batteries is controlled by the linkage output mechanism, this ensures the accuracy and consistency of each slitting and avoids errors in the slitting process.

[0031] 2. The present invention has a precise linkage effect between material pushing and cutting: the design of the linkage output mechanism and the belt transmission member enables the lithium battery material to flow efficiently between different devices. For example, the belt transmission member drives the push grid and the rear push frame to the target position through the linkage rod and the traction rod, effectively pushing the material into the working platform and cutting it. This design ensures the precise transmission between the pushing force and the cutting force. In the equipment, the setting of multiple trapezoidal limiting grooves ensures the precise guidance and positioning of each slider and the push grid. This not only improves the stability of the equipment, but also avoids the deviation of the material during the processing process. The moving path and sliding mode of slider one and slider two accurately control the motion trajectory of the entire system, so that each action is carried out on a predetermined path, thereby avoiding errors during operation.

[0032] 3. The present invention has an effective reverse guiding mechanism: The reverse guiding mechanism is designed to solve potential problems in the material pushing process. When the slider rises along the trapezoidal limiting groove, the reverse guiding mechanism is triggered, and the relative movement of the inclined slider avoids the misalignment of the material during pushing. This design improves the safety and stability of the system and prevents errors or jams during reverse pushing. The operating support platform can automatically flip and discharge the lithium battery material after the lithium battery material is cut through the automatic operation of the opening and closing plate. This automated opening and closing plate design not only improves the material circulation efficiency, but also reduces manual intervention, ensuring the efficiency and safety of the entire operation process.

[0047] Please refer to the attached Figure 1 -Attached Figure 5The linkage feeding mechanism 5 is located on the base 1, and cooperates with the limiting groove 34 for feeding lithium batteries. The linkage feeding mechanism 5 includes a guide wall 1 51 and a guide wall 2 52.

The guide wall 2 52 is fixedly connected to the side frame 21 and is adjacent to the side wall of the guide wall 1 51. A feeding frame 53 is fixedly connected to the top of the guide wall 2 52. A material placement table 54 is fixedly connected to the side wall of the guide wall 1 51 facing the guide wall 2 52. The material placement table 54 is connected to the guide wall There is a gap between the guide rail wall 1 and the guide rail wall 51 as the operating space of the linkage output mechanism 6, the material placement table 54 is provided with two embedding grooves 55 that pass through from top to bottom, and the feeding frame 53 is slidably connected to the top surface of the material placement table 54 and is located between the two embedding grooves 55. The inner side walls of the guide rail wall 1 51 and the guide rail wall 2 52 are both provided with a trapezoidal limiting groove 56, and the through opening of the trapezoidal limiting groove 56 is aligned with the limiting groove 34. The trapezoidal limiting groove 56 is set to an inverted isosceles trapezoidal structure, and the lithium battery material is pre-placed in the feeding frame 53 included in the linkage feeding mechanism 5, along the feeding frame 53. The material frame 53 is stacked longitudinally, and the bottom layer of lithium battery materials falls on the material placement table 54 and is located between the guide rail wall 1 51 and the guide rail wall 2 52. The two sets of sliders 69 slide in the trapezoidal limiting grooves 56 set on the guide rail wall 1 51 and the guide rail wall 2 52 respectively, and move linearly along the inverted trapezoidal top edge slide of the trapezoidal limiting groove 56. The rear push frame 64 also slides along the top surface of the material placement table 54 to push out the lithium battery coating that falls on the top surface of the material placement table 54 along the feed frame 53, and the lithium battery is also pushed along the material placement table 54 to the working support table 3. Slider 2 69 and slider 1 66 also enter the trapezoidal limiting groove 56. Slider 1 66 first enters the inclined slide of the trapezoidal limiting groove 56 and moves along the bottom slide of the trapezoidal limiting groove 56 until it enters another inclined surface and rises. At the same time, it drives the rear push frame 64 to descend along the embedded groove 55 to the bottom of the loading platform 54, and moves under the loading platform 54 and crosses the feed frame 53. Slider 1 66 rises along the oblique side of the trapezoidal limiting groove 56 and triggers the reverse guide mechanism 7.

[0048] Please refer to the attached Figure 1 -Attached Figure 8The linkage output mechanism 6 is located on the base 1, and cooperates with the material placement table 54 and the trapezoidal limiting groove 56 for overall transmission output. The linkage output mechanism 6 includes a belt transmission member 61 and a pushing grid 610. One end of the belt transmission member 61 is rotatably connected to the inner end of the convex shaft 25, and the other end of the belt transmission member 61 is rotatably connected to a linkage rod 62, and the other end of the linkage rod 62 is rotatably connected to a traction rod 63, and the other end of the traction rod 63 is rotatably connected to a rear push frame 64. The rear push frame 64 and the pushing grid 610 are set to an L-shaped structure, and the side wall of the rear push frame 64 opposite to the direction of the rear push frame 64 is fixedly connected with an additional rod 65, and the two ends of the additional rod 65 are rotatably connected with a slider 66, and the slider 66 is respectively slidably connected to the guide rail wall 51 and the guide rail wall The pusher grille 610 is slidably connected to the top surface of the material placement table 54 in the trapezoidal limiting groove 56 set in the guide rail wall 52. The pusher grille 610 is slidably connected to the top surface of the material placement table 54. The pusher grille 610 is connected to the side wall of the guide rail wall 51 and is rotated to connect the additional rod 68. The end of the additional rod 68 away from the pusher grille 610 is rotatably connected to the slider 69. The slider 69 is slidably connected in the trapezoidal limiting groove 56 set in the guide rail wall 51. The lateral length of the slider 69 is greater than the lateral length of the slider 66. As the belt transmission member 61 included in the linkage output mechanism 6 operates, the displacement of the belt end of the belt transmission member 61 guides the drag force to the linkage rod 62, driving the linkage rod 62 to also displace and unfold. The linkage rod 62 also guides the drag force to the traction rod 63, so that the traction rod 63 and the end of the traction rod 63 are increased. The installed slider 1 66 is dragged toward the inside of the side frame 21, and the slider 2 69 simultaneously drives the rear push frame 64 and the additional rod 1 65 installed on the inner side of the rear push frame 64 and the slider 2 69 on the other side end to drag toward the inside of the side frame 21. The two groups of sliders 2 69 slide in the trapezoidal limiting groove 56 provided on the guide rail wall 1 51 and the guide rail wall 2 52 respectively, and move linearly along the inverted trapezoidal top edge slide of the trapezoidal limiting groove 56. The rear push frame 64 also slides along the top surface of the material placement table 54 to push out the lithium battery cell paint that falls on the top surface of the material placement table 54 along the feeding frame 53, and the lithium battery cell is also pushed along the material placement table 54 to the working support table 3. When the additional rod 1 65 moves, it pushes the additional rod 2 68 through the installed drag rod 67. The slider 69 installed at one end of the second rod 68 slides along the trapezoidal limiting groove 56 set on the guide rail wall 51, and the pushing grid 610 installed at one end of the additional rod 68 and the lever 611 installed on the side wall of the pushing grid 610 are displaced accordingly. The pushing grid 610 is displaced along the top surface of the material placement platform 54 to the working support platform 3. At this time, the lever 611 will contact the linkage discharging mechanism 4 for the first time, and the lever 611 and the rear push frame 64 will continue to return to the displacement. After the arc contact rod 47 is separated from the lever 611, the opening and closing plate 41 is also rotated again to a position parallel to the working support platform 3 under the action of the return spring, and the lever 611 and the rear push frame 64 are pushed back to the top surface of the material placement platform 54 by the belt transmission member 61, the traction rod 63 and the linkage rod 62.Slider 2 69 and slider 1 66 also enter the trapezoidal limiting groove 56. Slider 1 66 first enters the inclined slideway of the trapezoidal limiting groove 56 and moves along the bottom slideway of the trapezoidal limiting groove 56 until it enters another inclined surface and rises, while driving the rear push frame 64 to descend along the embedded groove 55 to the bottom of the material placement table 54.

[0049] Please refer to the attached Figure 1 -Attached Fig. 9 The reverse guiding mechanism 7 is located on the linkage feeding mechanism 5, and can be slidably diverted and restricted in cooperation with the trapezoidal limiting groove 56. The reverse guiding mechanism 7 includes an inlay groove 71, which is arranged at an outer corner position of the trapezoidal limiting groove 56 away from the working bearing platform 3, and is located at the end of the top angle of the trapezoidal limiting groove 56. An inclined slider 72 is slidably connected inside the inlay groove 71, and a bayonet 73 is arranged at the bottom of the inclined slider 72. A positioning block 74 is fixedly connected to the bottom wall of the inlay groove 71, and the positioning block 74 is slidably connected in the bayonet 73. A retaining spring 75 is arranged between the inner side wall of the inclined slider 72 and the inner side wall of the inlay groove 71. The inclined surface of the inclined slider 72 faces the outer inclined surface of the trapezoidal limiting groove 56, and the inclined surface angle is greater than the inclined side of the trapezoidal limiting groove 56. The inclined slider 72 is pushed by the slider 1 66 to slide inside the inlay groove 71 because its own angle is greater than the bevel of the trapezoidal limiting groove 56. The inclined slider 72 completely enters the inlay groove 71 and squeezes the retaining spring 2 75. The slider 1 66 can pass through the bevel slide and enter the top slide of the trapezoidal limiting groove 56. The inclined slider 72 is also ejected by the retaining spring 2 75 until the bayonet 73 catches the positioning block 74. The inclined slider 72 returns to its original position and blocks the bevel slide of the trapezoidal limiting groove 56 to prevent the slider 1 66 from entering the bevel slide when pushing and feeding. With the linkage operation of the slitting blade 23, the operation processes of pushing, slitting and discharging are completed in sequence.

[0050] Please refer to the attached Figure 1 -Attached Fig. 9 The embodiment of the present invention provides a cutting method of a lithium battery cell cutting device capable of automatically replacing a lithium battery cell, comprising the following steps:

[0051] S1: Preparation and feeding process

[0052] The base 1 is carried on the ground as a carrier of the equipment structure. The static slitting mechanism 2 is installed on the base 1. The static slitting mechanism 2 includes a side frame 21 and a fixed knife frame 22. A plurality of slitting blades 23 are installed on the fixed knife frame 22 in an equidistant stacking form. The lithium battery material is pre-placed in the feeding frame 53 of the linkage feeding mechanism 5 and arranged in a longitudinal stacking manner. The bottom layer of lithium battery material is pushed to the material placement table 54 and is located between the guide rail wall 1 51 and the guide rail wall 2 52. The linkage output mechanism 6 starts to operate, and the belt transmission member 61 starts to drive. The displacement of the belt end of the belt transmission member 61 transmits the drag force to the linkage rod 62. The linkage rod 62 further transmits the drag force to the traction rod 63, driving the slider 1 66 and the slider 2 69 to move toward the inner direction of the side frame 21.

[0053] S2: Material pushing and cutting

[0054] The slider 2 69 simultaneously drives the rear push frame 64 and the additional rod 1 65 and the additional rod 2 68 to perform linear displacement along the trapezoidal limiting groove 56. The lithium battery material is pushed to the working carrier 3 by the push of the rear push frame 64. The lithium battery material is pushed to the working carrier 3 through the push grid 610, contacts the slitting blade 23, and is slitting. The push grid 610 embeds the material into its interval gap and slitting is performed uniformly.

[0055] S3: Cutting completion and return process

[0056] The belt transmission member 61 continues to operate, driving the linkage rod 62 to return, and the pusher grid 610 and the rear push frame 64 begin to return along the work platform 3 toward the direction of the linkage feeding mechanism 5. The pusher grid 610 is used to push the lithium battery material. When the pusher grid 610 reaches the linkage discharging mechanism 4, the lever 611 contacts the arc contact rod 47 for the second time. The lever 611 pushes the arc contact rod 47 to rotate along the limit slot 45, and pulls the sliding sleeve 44 and the hinge shaft 43 to open the opening and closing plate 41, discharge the material, and the lithium battery material slides out along the inclined work platform 3 and falls.

[0057] S4: Recovery and re-feeding preparation

[0058] Under the action of the return spring, the opening and closing plate 41 rotates again to a position parallel to the working support platform 3 and returns to the initial state. As the pushing grid 610 returns, the slider 66 enters the trapezoidal limiting groove 56 and triggers the reverse guide mechanism 7. The inclined slider 72 of the reverse guide mechanism 7 is pushed and enters the inlay groove 71. The slider 66 returns to the top slide through the bottom slide to prevent the slider 66 from entering the inclined slide. The slider 66, the slider 2 69, the lever 611 and the rear push frame 64 are driven by the belt transmission member 61 and are pushed back to the top surface of the material loading platform 54 to prepare for the next round of material feeding.

[0059] Working principle: First, the base 1 is used as a carrier of all equipment structures and is carried on the ground. A static slitting mechanism 2 for opposing cutting is installed on the top. The side frame 21 included in the static slitting mechanism 2 is fixed as a whole on the top side wall of the base 1. At the same time, the fixed knife holder 22 included in the static slitting mechanism 2 is installed on the base 1, and a multi-group cutting blade 23 is installed in an equidistant stacking form. The linkage output mechanism 6 in contact with it starts to operate on the linkage feeding mechanism 5, and then the working platform 3 and the linkage discharging mechanism 4 are started in linkage. The working platform 3 is also provided with an openable linkage discharging mechanism 4, and the lithium battery material is pre-placed in the feeding frame 53 included in the linkage feeding mechanism 5, and the lithium battery material on the bottom layer is stacked along the longitudinal direction of the feeding frame 53. It falls on the material placement table 54 and is located between the guide rail wall 1 51 and the guide rail wall 2 52. As the belt transmission member 61 included in the linkage output mechanism 6 operates, the belt end of the belt transmission member 61 is displaced to guide the dragging force to the linkage rod 62, driving the linkage rod 62 to also be displaced and unfolded. The linkage rod 62 also guides the dragging force to the traction rod 63, so that the traction rod 63 and the slider 1 66 installed at the end of the traction rod 63 are dragged toward the inside of the side frame 21. The slider 2 69 simultaneously drives the rear push frame 64 and the additional rod 1 65 installed on the inner side of the rear push frame 64 and the slider 2 69 on the other side end to be dragged toward the inside of the side frame 21. The two groups of sliders 2 69 slide in the trapezoidal limiting grooves 56 set on the guide rail wall 1 51 and the guide rail wall 2 52 respectively, and slide along the trapezoidal limiting grooves 56. The inverted trapezoidal top edge slide of the groove 56 moves linearly, and the rear push frame 64 also slides along the top surface of the material placement table 54 to push out the lithium battery cell paint that falls on the top surface of the material placement table 54 along the feeding frame 53, and the lithium battery cell is also pushed along the material placement table 54 to the working support platform 3. When the additional rod 1 65 moves, it pushes the additional rod 2 68 through the added drag rod 67, and the slider 2 69 installed at one end of the additional rod 2 68 slides along the trapezoidal limiting groove 56 set on the guide rail wall 1 51, and the pushing grille 610 installed at one end of the additional rod 2 68 and the lever 611 installed on the side wall of the pushing grille 610 are displaced. The pushing grille 610 moves along the top surface of the material placement table 54 to the working support platform 3. At this time, the lever 611 will contact the linkage output for the first time. The displacement of the lever 611 will first contact the arc contact rod 47 included in the linkage discharging mechanism 4, and push the arc contact rod 47 and the rotating wheel 46 fixed at the end of the arc contact rod 47 to rotate inside the sliding sleeve 44. The limiting slot 45 provided on the side wall of the outer shell of the sliding sleeve 44 directly limits the rotation angle of the arc contact rod 47 and the rotating wheel 46. When the arc contact rod 47 is pushed, the lever 611 will pass over the arc contact rod 47 and continue to move, and the arc contact rod 47 will be rebounded to the top bayonet 73 of the limiting slot 45 by the retaining spring 1 48, so as to avoid the arc contact rod 47 of the same height as the lever 611 causing the movement interference of the lever 611, and the slider 2 69 and the slider 1 66 will then enter the limiting slot 34 of the trapezoidal limiting slot 56.The pushing grid 610 and the rear pushing frame 64 also begin to push the lithium battery material to move on the working support platform 3, directly contact the slitting blade 23, and embed into the interval gap of the pushing grid 610, and uniformly cut the lithium battery. After the cutting is completed, the belt transmission member 61 continues to operate to drive the linkage rod 62 to return, and the pushing grid 610 and the rear pushing frame 64 begin to return along the working support platform 3 toward the direction of the linkage feeding mechanism 5. At this time, the pushing grid 610 mainly plays the role of pushing the material back. When the lever 611 reaches the linkage discharging mechanism 4 structure with the pushing grid 610, it contacts the arc contact rod 47 for the second time, and the lithium battery material is just on the opening and closing plate at this time. 41, the lever 611 pushes the arc contact rod 47, so that the arc contact rod 47 pulls the sliding sleeve 44 and the hinge shaft 43 to rotate along the limit slot 45, and the hinge shaft 43 pulls the opening and closing plate 41 along the fixed hinge 42 to rotate and open on the working carrier 3, and the lithium battery material on the top surface of the working carrier 3 slides out along the inclined working carrier 3, and the lever 611 and the rear push frame 64 continue to return to the displacement. After the arc contact rod 47 is separated from the lever 611, the opening and closing plate 41 is also rotated again to a position parallel to the working carrier 3 under the action of the return spring, and the lever 611 and the rear push frame 64 are driven by the belt transmission member 61, the traction rod 63 and the linkage The rod 62 is pushed back to the top surface of the material placement table 54, and the slider 2 69 and the slider 1 66 also enter the trapezoidal limiting groove 56. The slider 1 66 first enters the inclined slide of the trapezoidal limiting groove 56 and moves along the bottom slide of the trapezoidal limiting groove 56 until it enters another inclined surface and rises, while driving the rear push frame 64 to descend along the embedded groove 55 to the bottom of the material placement table 54, and moves under the material placement table 54 and crosses the feed frame 53 from another embedded groove 55 to the top of the material placement table 54. The slider 1 66 rises along the oblique side of the trapezoidal limiting groove 56 and triggers the reverse guide mechanism 7. The slider 1 66 contacts the reverse guide mechanism 7. The reverse guide mechanism 7 includes Because the angle of the inclined slider 72 is greater than the bevel of the trapezoidal limiting groove 56, it is pushed by the slider 1 66 to slide inside the inlay groove 71. The inclined slider 72 completely enters the inlay groove 71 and squeezes the second retaining spring 75. The slider 1 66 can pass through the bevel slide and enter the top slide of the trapezoidal limiting groove 56. The inclined slider 72 is also ejected by the second retaining spring 75 until the bayonet 73 clamps the positioning block 74. The inclined slider 72 returns to its original position and blocks the bevel slide of the trapezoidal limiting groove 56 to prevent the slider 1 66 from entering the bevel slide when pushing and feeding. With the linkage operation of the slitting blade 23, the operation processes of pushing, slitting, and discharging are completed in sequence.
