Description

Technical Field

[0001] This application relates to the field of lithium battery production technology, and in particular to the design of a tape module, a roll changing device, and processing equipment. Background Technology

[0002] As the new energy vehicle market continues to expand, the demand for power batteries is also increasing, requiring power battery die-cutting equipment to achieve higher production capacity. For die-cutting equipment, when the working strip is nearly depleted, the start of a spare strip needs to be attached to the end of the working strip to continue die-cutting. The speed and quality of the strip connection significantly impact the production speed and quality of the die-cutting equipment.

[0003] During tape splicing, the adhesive preparation module pulls a section of tape (e.g., single-sided tape) from the tape roll and cuts it to separate it from the roll. Then, the splicing module aligns the end of the working tape with the beginning of the spare tape. The adhesive application module then applies one section of tape to the same side of both the working tape's end and the spare tape's beginning. Finally, another section of tape is applied to the opposite side of both ends, completing the tape splicing.

[0004] In related technologies, when the adhesive application module adheres the tape to the working material belt and the spare material belt, the cutter of the tape receiving module is prone to damaging the adhesive application module, resulting in high maintenance costs for the adhesive application module.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] Reference Figures 1 to 4According to a first aspect embodiment of this application, the tape receiving module includes a connecting base 110, an adsorption component 200, a cutting component 300, and a limiting component 400. The adsorption component 200 includes a first suction cup 210 and a second suction cup 220, both mounted on the connecting base 110. The first and second suction cups 210 are arranged side-by-side, with a receiving slot 230 formed between them. The first suction cup 210 is used to adsorb a first tape 521, and the second suction cup 220 is used to adsorb a second tape 522.

[0054] The cutting assembly 300 includes a cutter 310 and a first drive member 320 (see reference). Figure 3 The cutter 310 is mounted on the connecting seat 110, and at least a portion of the cutter 310 is located in the receiving slot 230. The cutter 310 extending from the receiving slot 230 is used to cut the first material strip 521 adsorbed by the first suction cup 210, and the cutter 310 extending from the receiving slot 230 is also used to cut the second material strip 522 adsorbed by the second suction cup 220. The first driving member 320 is used to drive the first suction cup 210 and the second suction cup 220 away from the connecting seat 110 so that the cutter 310 extending from the receiving slot 230 is completely returned to the receiving slot 230.

[0055] The limiting assembly 400 includes a second driving member 410 and a limiting member 420. The second driving member 410 is mounted on the connecting base 110 and is used to drive the limiting member 420 to move to a first position or a second position. When the limiting member 420 is in the first position (refer to...), Figure 3 , Figure 3 The limiting member 420 is in the first position. The limiting member 420 can restrict the movement of the first suction cup 210 and the second suction cup 220 towards the connecting seat 110, so that the cutter 310 is completely in the receiving slot 230. When the limiting member 420 is in the second position (refer to...), Figure 4 , Figure 4 The limiting member 420 is in the second position. The limiting member 420 can not restrict the movement of the first suction cup 210 and the second suction cup 220 close to the connecting seat 110, so that the cutter 310 has the condition to extend from the accommodating slit 230.

[0056] The tape-attaching module according to the embodiments of this application has at least the following beneficial effects: When the limiting member 420 is in the second position, under the push of the adhesive-attaching module 600, the first suction cup 210 and the second suction cup 220 can normally approach the connecting seat 110, thereby allowing the cutter 310 to protrude from the receiving seam 230, completing the cutting of the first material tape 521 adsorbed by the first suction cup 210 and the cutting of the second material tape 522 adsorbed by the second suction cup 220, thereby aligning the first material tape 521 and the second material tape 522; when the limiting member 420 is in the first position, the adhesive-attaching module 600 can attach the tape to the first material tape 521 adsorbed by the first suction cup 210 and the second material tape 522 adsorbed by the second suction cup 220, and the first suction cup 210 and the second suction cup 220 will not approach the connecting seat 110, and the cutter 310 is completely in the receiving seam 230 and not exposed, thereby effectively reducing the probability of the cutter 310 damaging the adhesive-attaching module 600.

[0057] Specifically, the first material strip 521 can be a working material strip, and the second suction cup 220 can be a spare material strip, and the material strip can be an electrode or a diaphragm.

[0058] Specifically, the second driving component 410 can be one of the following: a second cylinder, a second linear motor, a hydraulic cylinder, an electric cylinder, a motor-driven lead screw and nut mechanism, a motor-driven gear and rack mechanism, a motor-driven sprocket and chain mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven crank and slider mechanism. Preferably, the second driving component 410 is a second cylinder.

[0059] It should be noted that the tape splicing module usually also includes a third suction cup 240, which is used to pick up the tape 530 (see reference). Figure 8 The third suction cup 240 is also mounted on the connecting base 110, which can rotate relative to the mounting base 120 about a front-rear axis, thereby switching the positions of the third suction cup 240, the first suction cup 210, and the second suction cup 220. For example, Figure 2 The third suction cup 240, the first suction cup 210, and the second suction cup 220 are, in fact, Figure 1 The third suction cup 240, the first suction cup 210, and the second suction cup 220 rotate counterclockwise around the axis in the front-back direction (see reference). Figure 2 (Viewed from front to back) Rotated 90° to the position.

[0060] Reference Figure 1 and Figure 3 In some embodiments of this application, when the limiting member 420 is in the first position, one end of the limiting member 420 is located between the first suction cup 210 and the connecting seat 110, and the other end of the limiting member 420 is located between the second suction cup 220 and the connecting seat 110.

[0061] By positioning the limiting member 420 between the first suction cup 210 and the connecting seat 110, and between the second suction cup 220 and the connecting seat 110, the first suction cup 210 and the second suction cup 220 can be well limited, reducing the probability that the first suction cup 210 and the second suction cup 220 will approach the connecting seat 110 due to vibration or other reasons, thereby better ensuring that the cutter 310 is completely within the receiving slot 230.

[0062] Furthermore, the limiting member 420 provides stable positioning for the first suction cup 210 and the second suction cup 220, which facilitates the coplanarity and alignment of the first material strip 521 and the second material strip 522. During adhesive application, the adhesive tape 530 (refer to...) Figure 8 It can evenly cover the connection part of the first material strip 521 and the second material strip 522, and improve the firmness of the connection between the first material strip 521 and the second material strip 522.

[0063] In another embodiment, when the limiting member 420 is in the first position, two limiting members 420 may be provided, with the two limiting members 420 respectively located on opposite sides of the first suction cup 210 and the second suction cup 220. The two limiting members 420 clamp the opposite ends of the first suction cup 210 (e.g., clamp the front end and rear end of the first suction cup 210), and at the same time, the two limiting members 420 clamp the opposite ends of the second suction cup 220 (e.g., clamp the front end and rear end of the second suction cup 220), thereby also restricting the movement of the first suction cup 210 and the second suction cup 220 toward the connecting seat 110.

[0064] Reference Figure 4 In the improved embodiment described above, two limiting members 420 are provided. When the limiting members 420 are in the first position, the two limiting members 420 can respectively abut against the opposite ends of the first suction cup 210 (e.g., the front end and the rear end of the first suction cup 210), and the two limiting members 420 can also respectively abut against the opposite ends of the second suction cup 220 (e.g., the front end and the rear end of the second suction cup 220).

[0065] By having two limiting members 420 respectively abut against the opposite ends of the first suction cup 210, the force on the first suction cup 210 can be balanced, thereby providing stable support for the first suction cup 210; similarly, the two limiting members 420 can provide stable support for the second suction cup 220. This is beneficial for making the first material strip 521 and the second material strip 522 coplanar and aligned.

[0066] Reference Figure 3 In some embodiments of this application, the first drive member 320 includes one of an elastic member, a first cylinder, and a first linear motor.

[0067] The elastic element, the first cylinder, and the first linear motor can all drive the first suction cup 210 and the second suction cup 220 away from the connecting seat 110. They are simple in structure and low in cost, which helps to reduce the equipment cost of the tape module.

[0068] In another embodiment, the first driving member 320 may also be one of the following: hydraulic cylinder, electric cylinder, motor-driven screw and nut mechanism, motor-driven gear and rack mechanism, motor-driven sprocket and chain mechanism, motor-driven synchronous pulley and synchronous belt mechanism, and motor-driven crank and slider mechanism.

[0069] Reference Figure 3 In the improved embodiment described above, the elastic element includes a compression spring 321. One end (e.g., the upper end) of the compression spring 321 abuts against the connecting seat 110, and the other end (e.g., the lower end) of the compression spring 321 abuts against at least one of the first suction cup 210 and the second suction cup 220.

[0070] The compression spring 321 is inexpensive to obtain and reliable in function, which helps to reduce the equipment cost of the tape module.

[0071] In other embodiments, the elastic element may also be an elastic rubber column, an elastic silicone column, a gas spring, a wave spring, or other parts.

[0072] It should be noted that the other end (e.g., the lower end) of the compression spring 321 abuts against at least one of the first suction cup 210 and the second suction cup 220 because when the other end of the compression spring 321 abuts against the first suction cup 210, the second suction cup 220 may be abutted by other types of elastic elements, such as a gas spring. Other cases follow the same principle.

[0073] Reference Figure 3 In the improved embodiment described above, there are two or more compression springs 321, and at least one of the first suction cup 210 and the second suction cup 220 is held against the other end of the two or more compression springs 321.

[0074] By setting two or more compression springs 321, it can be ensured that at least one of the first suction cup 210 and the second suction cup 220 is subjected to uniform force during the reset process, and will not tilt due to excessive elasticity on one side. This helps to reduce the probability of alignment deviation of the first material strip 521 and the second material strip 522 due to tilting.

[0075] Specifically, the first suction cup 210 can be held abutted by the other end of two, three, four or other numbers of compression springs 321, and the second suction cup 220 can be held abutted by the other end of two, three, four or other numbers of compression springs 321.

[0076] Reference Figure 5In some embodiments of this application, the cutter 310 is detachably mounted on the connector 110.

[0077] When the blade of the cutter 310 experiences wear, chipping, or other problems, its cutting accuracy will decrease (for example, the cut edges of the first or second strip 521 will be rough, or the cut dimensions will be off). When the cutter 310 is detachably installed on the connector 110, maintenance can be completed by removing and replacing only the cutter 310, without disassembling the entire strip assembly. This significantly reduces maintenance time and thus lowers repair costs.

[0078] Reference Figure 6 and Figure 7 In the improved embodiment described above, the cutting assembly 300 further includes a fixing member 340. The connecting seat 110 has a groove 111, and one end of the cutter 310 is inserted into the groove 111. The fixing member 340 is connected to the connecting seat 110, and the fixing member 340 can move relative to the connecting seat 110 to a third position or a fourth position. When the fixing member 340 is in the third position (refer to...), Figure 6 , Figure 6 The fixing member 340 is located in the third position. The fixing member 340 can abut against the cutter 310 to limit the movement of the cutter 310 away from the groove 111. When the fixing member 340 is in the fourth position (refer to...), Figure 7 , Figure 7 The fixing member 340 is located in the fourth position. The fixing member 340 can disengage from the cutter 310 so that the cutter 310 can disengage from the groove 111.

[0079] The cutter 310 can be quickly removed by switching the retainer 340 from the third position to the fourth position and by pulling the cutter 310 out of the groove 111. Then, a new cutter 310 can be quickly installed by inserting it into the groove 111 and switching the retainer 340 from the fourth position to the third position. In other words, by setting up the retainer 340 and the groove 111, it is convenient to quickly replace the cutter 310.

[0080] Specifically, the cutter 310 includes a base 311 and a blade 312, with the blade 312 fixed to the base 311 by fasteners. The groove 111 is T-shaped, and the base 311 has a T-shaped boss 313. After the boss 313 is inserted into the groove 111, the blade 312 is positioned relative to the connecting seat 110 along the width direction of the blade 312 (refer to...). Figure 6 (i.e., the left-right direction) and the thickness direction (refer to) Figure 6 The movement of the blade 312 (i.e., in the vertical direction) is restricted, and the blade 312 can only move relative to the connecting seat 110 along the length direction of the blade 312 (refer to...). Figure 6 (i.e., forward and backward movement).

[0081] After the fixing member 340 is rotated to the third position, the movement of the blade 312 relative to the connecting seat 110 along the length direction of the blade 312 can be restricted.

[0082] Specifically, the fixing member 340 can be rotatably connected to the connecting seat 110, thereby switching between the third and fourth positions. When the fixing member 340 is rotated to the third position, it can be pre-tightened by the wing bolt 330 that is threaded into the connecting seat 110 to prevent the fixing member 340 from loosening accidentally. In addition, the fixing member 340 can also be slidably connected to the connecting seat 110, for example, the fixing member 340 can slide relative to the connecting seat 110 in the left and right direction.

[0083] In some embodiments of this application, the first suction cup 210 and the second suction cup 220 are fixedly connected.

[0084] By fixing the first suction cup 210 and the second suction cup 220 together, the first suction cup 210 and the second suction cup 220 can move synchronously, which facilitates the alignment of the first material strip 521 and the second material strip 522. In addition, the first driving member 320 can simultaneously push the first suction cup 210 and the second suction cup 220, thereby simplifying the structure of the receiving module and reducing the production cost of the receiving module.

[0085] Reference Figure 8 According to a second aspect embodiment of the present application, the roll changing device includes a tape splicing module and an adhesive application module 600. The adhesive application module 600 is used to attach adhesive tape to a first tape 521 adsorbed by a first suction cup 210 and a second tape 522 adsorbed by a second suction cup 220.

[0086] The roll changing device according to the embodiments of this application has at least the following beneficial effects: by using the above-mentioned tape splicing module, the probability of damage to the adhesive application module 600 can be effectively reduced, thereby helping to reduce the maintenance cost of the roll changing device.

[0087] It should be noted that the adhesive application module 600 has a structure that is basically the same as the tape attaching module (the adhesive application module 600 does not have the first driving component 320, but the other structures are the same). The adhesive application module 600 attaches the adhesive tape 530 to the first material tape 521 adsorbed by the first suction cup 210 and the second material tape 522 adsorbed by the second suction cup 220 through the third suction cup 240. This is prior art and will not be described in detail here.

[0088] Reference Figure 8 The processing apparatus according to a third aspect embodiment of the present application includes a roll changing device and a processing device 510, the processing device 510 being used to process a first strip 521 and a second strip 522 connected by a tape.

[0089] The processing equipment according to the embodiments of this application has at least the following beneficial effects: by using the above-described roll changing device, it is beneficial to reduce the maintenance cost of the processing equipment.

[0090] Specifically, the processing device 510 can be a die-cutting device to cut tabs on the first strip 521 and the second strip 522. Alternatively, the processing device 510 can be a cell winding device to wind up the cell.

[0091] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
