Description

Technical Field

[0001] This utility model belongs to the field of lithium battery technology, and specifically relates to a gripper for Mylar film in lithium battery packs and a Mylar film packing device. Background Technology

[0002] In battery manufacturing, Mylar film, a polyester polymer film, is widely used for wrapping the outer layer of battery cells due to its high strength, heat resistance, weather resistance, and excellent insulation properties, achieving insulation protection, enhanced sealing, and improved performance. In existing technologies, square power batteries require two bare cells connected in series before being wrapped with a Mylar film. The Mylar film is then heat-sealed to an insulating sheet to form an integrated packaging sheet, ensuring structural stability and safety of the cell. The process of wrapping the cells with Mylar film typically employs a vertical placement method. The cells are gripped by claws and lowered vertically onto a wrapping platform. The wrapping assembly then wraps the Mylar film from the bottom of the cell upwards to the top cover and completes the heat sealing. However, during the vertical descent, the outer Mylar film at the bottom of the cell is easily lifted due to air resistance, exposing the electrode. Exposed negative electrode electrodes are prone to scratches, powder shedding, and even metal layer damage, seriously threatening cell quality and safety. Reducing the cell descent speed leads to substandard production efficiency, wasted capacity, and increased costs.

[0003] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem this invention aims to solve is how to effectively avoid electrode damage caused by the Mylar film being lifted during the cell descent process while improving production efficiency.

[0005] To address the aforementioned technical problems, this utility model provides a gripper for Mylar film in lithium battery packs. The gripper includes a driver, a clamping part, and a pressure applying part. The clamping part includes two symmetrically arranged clamping arms, each connected to the driver. The driver drives the two clamping arms to move closer or further away. The pressure applying part includes two claw heads, each corresponding to one of the two clamping arms. When a battery cell covered with Mylar film is located between the two clamping arms, the claw heads extend obliquely from the clamping arms toward the battery cell, and the contact position between the claw heads and the Mylar film is located between the top and bottom sides of the battery cell. The driver drives the two clamping arms to move closer, causing the two claw heads to clamp the Mylar film onto the battery cell.

[0006] Optionally, the ratio of the distance between the contact point of the claw and the Mylar film and the bottom side of the battery cell to the distance between the top side and the bottom side of the battery cell is between one-sixth and one-fifth.

[0007] Optionally, the clamping arm includes a first clamping member connected to the driver and a second clamping member connected to the first clamping member and the claw head, respectively.

[0008] Optionally, the first clamping member includes an inner cylinder, an outer cylinder, and a pusher disposed inside the outer cylinder. The inner cylinder is connected to the second clamping member, and the outer cylinder is sleeved outside the inner cylinder. The inner cylinder and the outer cylinder are connected by a linear guide rail. The push rod of the pusher is connected to the inner cylinder to drive the inner cylinder to extend and retract the second clamping member along the length extension direction of the linear guide rail.

[0009] Optionally, the claw head forms an acute angle with respect to the bottom side surface of the battery cell.

[0010] Optionally, an elastic buffer layer is provided on the side of the claw head closest to the battery cell.

[0011] Optionally, the gripper also includes a pressure sensor covering the side of the gripper head near the battery cell.

[0012] Optionally, the gripper further includes a displacement mechanism connected to the driver, the displacement mechanism being used at least to drive the driver and the gripped battery cell to move up and down.

[0013] Optionally, the displacement mechanism includes a lateral motion module and a vertical motion module connected to the lateral motion module and the driver respectively. The lateral motion module is used to drive the vertical motion module to move laterally along the length extension direction of the lateral motion module, and the vertical motion module is used to drive the driver to move up and down along the length extension direction of the vertical motion module. The length extension direction of the lateral motion module is perpendicular to the length extension direction of the vertical motion module.

[0014] According to another aspect of the present invention, the present invention also provides a Mylar film coating device, including the aforementioned grippers for Mylar film coating lithium battery packs.

[0015] Beneficial effects:

[0016] This invention provides a gripper for Mylar film in lithium battery packs. Two gripping arms of the gripping part are connected to a driver, which drives the two gripping arms to move closer or further apart. Two claws of the pressure-applying part are correspondingly positioned to each of the two gripping arms. When a battery cell covered with Mylar film is positioned between the two gripping arms, the claws extend at an angle from the gripping arms towards the battery cell, with the contact point between the claws and the Mylar film located between the top and bottom sides of the battery cell. The driver drives the two gripping arms to move closer, clamping the Mylar film onto the battery cell. Thus, when the battery cell is placed between the two gripping arms, the driver drives the two gripping arms to move closer, clamping the Mylar film onto the battery cell. This ensures that as the battery cell descends, the claws maintain pressure on the Mylar film, preventing the Mylar film from lifting during descent, maintaining the integrity of the battery cell, and improving production efficiency. This achieves the technical effect of improving production efficiency while effectively avoiding electrode damage caused by the Mylar membrane being lifted during cell descent.

[0026] This utility model provides a gripper for Mylar film 6 in a lithium battery pack, as shown in Embodiment 1. Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of a gripper for Mylar film in a lithium battery pack, provided by an embodiment of this utility model. Figure 2This is a schematic diagram of the clamping arm in a gripper for Mylar film in a lithium battery pack, provided by an embodiment of this utility model. Figure 3 This is a schematic diagram of the jaw head structure of a gripper for a Mylar film in a lithium battery pack according to an embodiment of the present invention. The gripper for a Mylar film in a lithium battery pack according to this embodiment includes a driver 1, a clamping part 2, and a pressure applying part 3. The clamping part 2 includes two clamping arms 21, which are symmetrically arranged and connected to the driver 1. The driver 1 drives the two clamping arms 21 to move closer to or further away from each other. The pressure applying part 3 includes two jaw heads 31, which are correspondingly arranged with the two clamping arms 21. The jaw heads 31 are connected to the corresponding clamping arms 21. When a battery cell 5 covered with a Mylar film 6 is located between the two clamping arms 21, the jaw heads 31 extend obliquely from the clamping arms 21 towards the battery cell 5, and the contact position between the jaw heads 31 and the Mylar film 6 is located between the top side 51 and the bottom side 52 of the battery cell 5. The driver 1 drives the two clamping arms 21 to move closer to each other, which in turn drives the two claws 31 to clamp the Mylar membrane 6 onto the cell 5.

[0027] The driver 1 may include a motor, cylinder, etc. For example, the driver 1 may include a lead screw and nut transmission mechanism driven by a servo motor. The lead screw in the lead screw and nut transmission mechanism is connected to the output shaft of the servo motor, and the nut can reciprocate linearly along the lead screw. The two clamping arms 21 of the clamping part 2 are fixedly connected to the nut through connecting parts. When the servo motor is running, the rotation of the lead screw will drive the nut to move along the lead screw axis, thereby driving the two clamping arms 21 to move closer or further apart.

[0028] Mylar film 6 is wrapped around the outer surface of cell 5. When the driver 1 drives the two clamping arms 21 to move closer to each other, it will drive the two claws 31 to move together, and finally clamp Mylar film 6 to the surface of cell 5.

[0029] In this embodiment, the two clamping arms 21 of the clamping part 2 are respectively connected to the driver 1. The driver 1 is used to drive the two clamping arms 21 to move closer to each other or further away from each other. The two claws 31 of the pressure part 3 are arranged one-to-one with the two clamping arms 21. The claws 31 are connected to the corresponding clamping arms 21. When the battery cell 5 covered with Mylar film 6 is located between the two clamping arms 21, the claws 31 extend at an angle from the clamping arms 21 toward the battery cell 5. The contact position between the claws 31 and Mylar film 6 is located between the top side 51 and the bottom side 52 of the battery cell 5. By driving the two clamping arms 21 to move closer to each other through the driver 1, the two claws 31 can clamp the Mylar film 6 onto the battery cell 5. When the battery cell 5 is placed between the two clamping arms 21, the driver 1 drives the two clamping arms 21 to move closer, causing the two claws 31 to clamp the Mylar film 6 onto the battery cell 5. This ensures that as the battery cell 5 descends, the claws 31 maintain pressure on the Mylar film 6, preventing the Mylar film 6 from lifting during descent and maintaining the integrity of the battery cell 5, thus improving production efficiency. This achieves the technical effect of improving production efficiency while effectively preventing electrode damage caused by the lifting of the Mylar film 6 during the descent of the battery cell 5.

[0030] In one implementation, the ratio of the distance between the contact point of the claw 31 and the Mylar film 6 and the bottom side surface 52 of the battery cell 5 to the distance between the top side surface 51 and the bottom side surface 52 of the battery cell 5 ranges from one-sixth to one-fifth. The contact point between the claw 31 and the Mylar film 6 refers to the position where the end of the claw 31 contacts the bottom side surface 52 of the battery cell 5. For example, the position where the end of the claw 31 contacts the bottom side surface 52 of the battery cell 5 is a straight line parallel to the bottom side surface 52 of the battery cell 5. The distance between the top side surface 51 and the bottom side surface 52 of the battery cell 5 refers to the height of the battery cell 5 in the vertical direction. Assuming the distance between the contact point of the claw 31 and the Mylar film 6 and the bottom side surface 52 of the battery cell 5 is A, the distance between the bottom side surface 52 and the distance between the top side surface 51 and the bottom side surface 52 of the battery cell 5 is... If B is the value of the electrode, then A / B = H, and the value of H ranges from one-sixth to one-fifth, i.e., 1 / 6 ≤ H ≤ 1 / 5. This ensures that when the claw 31 clamps the Mylar film 6, as the cell 5 descends, the direction and position of the pressure applied by the claw 31 to the Mylar film 6 will ensure that the claw 31 always maintains effective pressure on the Mylar film 6. This also prevents the Mylar film 6, located at the bottom of the cell 5, from being lifted up during the descent due to uneven force or insufficient pressure. This helps to ensure the integrity of the cell 5 and reduces the damage to the electrode caused by the lifting of the Mylar film 6.

[0031] In some embodiments, the clamping arm 21 includes a first clamping member 211 and a second clamping member 212. The first clamping member 211 is connected to the driver 1, and the second clamping member 212 is connected to both the first clamping member 211 and the claw head 31. For example, the claw head 31 can be fixed to the second clamping member 212 by welding. The first clamping member 211 and the second clamping member 212 can also be detachably connected to facilitate maintenance and replacement of either the first clamping member 211 or the second clamping member 212. Alternatively, the first clamping member 211 and the second clamping member 212 can be integrally formed.

[0032] In some embodiments, the first clamping member 211 includes an inner cylinder, an outer cylinder, and a pusher. The pusher includes a motor or a cylinder and is disposed inside the outer cylinder. The inner cylinder is connected to the second clamping member 212, and the outer cylinder is sleeved on the outside of the inner cylinder. The inner cylinder and the outer cylinder are connected by a linear guide rail. The push rod of the pusher is connected to the inner cylinder to drive the inner cylinder to move the second clamping member 212 along the length extension direction of the linear guide rail. Those skilled in the art will understand that the specific structure of the inner cylinder, outer cylinder, pusher, and linear guide rail in the gripper for Mylar film of lithium battery pack provided in Embodiment 1 of this utility model is not limited. It is only necessary to realize that the outer cylinder is sleeved on the outside of the inner cylinder, the inner cylinder can slide inside the outer cylinder, and one end of the linear guide rail can be fixed inside the outer cylinder away from the inner cylinder. The outside of the inner cylinder can be toothed with the guide rail. After the push rod of the pusher fixed inside the outer cylinder away from the inner cylinder is connected to the inner cylinder, the extension and retraction of the push rod of the pusher will drive the inner cylinder to extend and retract along the length extension direction of the linear guide rail. Pushing the inner cylinder will drive the second clamping member 212 to extend and retract along the length extension direction of the linear guide rail, so that the position of the gripper head 31 can be finely adjusted, which can adapt to the battery cell 5 of different heights and effectively clamp the Mylar film 6 of the battery cell 5 of different heights.

[0033] In some embodiments, the claw 31 forms an acute angle with respect to the bottom side surface 52 of the battery cell 5, i.e., as shown in the figure. Figure 2 As shown, the angle between the claw head 31 and the horizontal plane is an acute angle, which ensures that when the claw head 31 clamps the Mylar film 6, as the cell 5 descends, the direction of the pressure applied by the claw head 31 to the Mylar film 6 can always ensure that the claw head 31 can always apply stable pressure to the Mylar film 6, preventing the Mylar film 6 from being lifted due to improper force, ensuring the integrity of the cell 5, and helping to reduce electrode damage.

[0034] In some embodiments, an elastic buffer layer 311, comprising silicone, is provided on the side of the claw 31 closest to the battery cell 5. When clamping the Mylar membrane 6, the elastic buffer layer 311 on the side of the claw 31 closest to the battery cell 5 can buffer the impact force on the Mylar membrane 6 during clamping, preventing damage to the Mylar membrane 6 due to excessive clamping force. When the battery cell 5 begins to descend, due to the presence of the elastic buffer layer 311, the claw 31 can adaptively adjust itself according to the force changes on the Mylar membrane 6 during descent, maintaining pressure on the Mylar membrane 6 at all times, thus preventing the Mylar membrane 6 from being lifted during descent.

[0035] In some embodiments, the gripper also includes a pressure sensor 312, which is located on the side of the gripper head 31 near the battery cell 5. The pressure sensor 312 is used to collect the pressure applied to the Mylar membrane 6 by the gripper head 31 in real time. The pressure sensor 312 outputs the collected pressure applied to the Mylar membrane 6 to an external display, which allows the operator to check in real time whether the pressure applied to the Mylar membrane 6 is within the normal range. If an abnormal pressure is detected, the operator can adjust the clamping force of the gripping arm 21 by adjusting the operating parameters of the servo motor according to the preset pressure range, so that the gripper head 31 always maintains a suitable pressure on the Mylar membrane 6.

[0036] In some embodiments, the gripper also includes a displacement mechanism connected to the driver 1. The displacement mechanism is at least used to drive the driver 1 and the clamped battery cell 5 to move up and down. For example, the displacement mechanism can drive the driver 1 to move up and down in the vertical direction, or the displacement mechanism can drive the driver 1 to move left and right in the horizontal direction.

[0037] In some embodiments, the displacement mechanism includes a lateral motion module and a vertical motion module. The vertical motion module is connected to both the lateral motion module and the driver 1. The lateral motion module drives the vertical motion module to move laterally along its length extension direction, and the vertical motion module drives the driver 1 to move vertically along its length extension direction. The length extension directions of the lateral and vertical motion modules are perpendicular to each other. Those skilled in the art will understand that the specific structure of the lateral and vertical motion modules in the gripper for Mylar film in a lithium battery pack provided in Embodiment 1 of this utility model is not limited. For example, the lateral motion module may include a motor and a lead screw, with the lead screw extending horizontally in a left-right direction within the horizontal plane. The lead screw is threadedly connected to the vertical motion module, and the motor drives the lead screw to move the vertical motion module left and right in the horizontal plane. The vertical motion module may also include a motor and a lead screw, with the lead screw extending vertically. The lead screw is threadedly connected to the driver 1, and the motor drives the lead screw to rotate, thereby driving the driver 1 to move vertically. Alternatively, the driver 1 can be a linear motor, with its mover connected to the two clamping arms 21 of the clamping part 2, driving the two clamping arms 21 to move closer together and clamp the battery cell 5 covered with Mylar film 6. The lateral motion module of the displacement mechanism can be a ball screw type lateral guide rail, with the ball screw driven by a stepper motor, and the vertical motion module can be a chain-type lifting mechanism. The lateral motion module is used to drive the vertical motion module to move laterally along the length extension direction of the lateral motion module, and the vertical motion module is used to drive the driver 1 to move up and down along the length extension direction of the vertical motion module. The length extension direction of the lateral motion module is perpendicular to the length extension direction of the vertical motion module, causing the battery cell 5 covered with Mylar film 6, held by the two claws 31, to move up and down or left and right laterally.

[0038] To provide a detailed description of the Mylar film coating device provided by this utility model, the above embodiment 1 provides a detailed description of a gripper for Mylar film coating of lithium battery packs. Based on the same utility model concept, this application also provides a Mylar film coating device, as detailed in embodiment 2.

[0039] Embodiment 2 of this utility model provides a Mylar film packing device, including the grippers described above for Mylar film packing of lithium batteries.

[0040] This utility model provides a Mylar film coating device. The two clamping arms 21 of the clamping part 2 are respectively connected to the driver 1. The driver 1 is used to drive the two clamping arms 21 to move closer or further apart. The two claws 31 of the pressure application part 3 are arranged one-to-one with the two clamping arms 21. The claws 31 are connected to the corresponding clamping arms 21. When the battery cell 5 covered with Mylar film 6 is located between the two clamping arms 21, the claws 31 extend at an angle from the clamping arms 21 toward the battery cell 5. The contact position between the claws 31 and the Mylar film 6 is located between the top side 51 and the bottom side 52 of the battery cell 5. By driving the two clamping arms 21 to move closer together through the driver 1, the two claws 31 can clamp the Mylar film 6 onto the battery cell 5. When the battery cell 5 is placed between the two clamping arms 21, the driver 1 drives the two clamping arms 21 to move closer, causing the two claws 31 to clamp the Mylar film 6 onto the battery cell 5. This ensures that as the battery cell 5 descends, the claws 31 maintain pressure on the Mylar film 6, preventing the Mylar film 6 from lifting during descent and maintaining the integrity of the battery cell 5, thus improving production efficiency. This achieves the technical effect of improving production efficiency while effectively preventing electrode damage caused by the lifting of the Mylar film 6 during the descent of the battery cell 5.

[0041] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
