Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a battery cell adhesive bonding device and battery cell adhesive bonding equipment. Background Technology

[0002] The battery cell is one of the most important components of a battery. To prevent the layers of material (including the separator and electrode sheets) from loosening, adhesive tape needs to be applied to the outer layer of the cell. In related technologies, the tape is first pulled by a tape-pulling mechanism, then cut by a cutting mechanism, and finally transferred to an adhesive-applying mechanism for application. Adhesive-applying devices using this method require numerous mechanisms, resulting in high costs, large space requirements, and low efficiency due to the multiple application steps. Summary of the Invention

[0003] Therefore, it is necessary to provide a battery cell adhesive application device that has the characteristics of low cost, small space occupation and high adhesive application efficiency.

[0005] Unwinding mechanism;

[0006] The adhesive application mechanism can fix the adhesive tape unwound from the unwinding mechanism onto the adhesive application mechanism;

[0007] A cutting mechanism for cutting the tape on the adhesive applicator; and

[0008] A support mechanism is used to abut the cylindrical battery cell located on the support mechanism against the adhesive application mechanism so that the cut adhesive tape is applied to the outer periphery of the cylindrical battery cell.

[0009] In one embodiment, the adhesive applicator includes an adhesive applicator roller.

[0010] In one embodiment, the unwinding mechanism unwinds the tape at the adhesive receiving station, the cutting mechanism cuts the tape at the adhesive cutting station, and the cylindrical battery cell located on the support mechanism abuts against the adhesive applying mechanism at the adhesive applying station. In the circumferential direction of the adhesive applying mechanism, the adhesive cutting station is located between the adhesive receiving station and the adhesive applying station.

[0011] In one embodiment, the adhesive receiving station and the adhesive application station correspond to the two ends of half the circumference of the adhesive application mechanism, respectively.

[0012] The adhesive receiving station corresponds above the adhesive application mechanism, and the adhesive application station corresponds below the adhesive application mechanism; and / or

[0013] The glue-cutting station corresponds precisely to the center of half the circumference of the glue-applying mechanism.

[0014] In one embodiment, the adhesive applicator has a vacuum adsorption section that can fix the adhesive tape.

[0015] In one embodiment, the vacuum adsorption section extends circumferentially along the adhesive application mechanism.

[0016] In one embodiment, the adhesive applicator has a cutter clearance groove, and the cutting mechanism cuts the tape at the cutter clearance groove.

[0017] In one embodiment, there are multiple cutter clearance slots, which are arranged at intervals along the circumference of the adhesive applicator.

[0019] The cutting mechanism and the supporting mechanism are respectively arranged facing the two adjacent cutter clearance slots; and / or

[0020] The cutter has four clearance grooves.

[0021] In one embodiment, the support mechanism is used to provide rolling support for the cylindrical battery cell, so that when the cylindrical battery cell abuts against the adhesive applicator, the rotation of the adhesive applicator causes the cylindrical battery cell to rotate in the opposite direction so that the cut adhesive tape is applied to the outer periphery of the cylindrical battery cell.

[0022] In one embodiment, the support mechanism includes a first rolling support and a second rolling support arranged at intervals. The arrangement direction of the first rolling support and the second rolling support is parallel to the rotation axis of the adhesive applicator. The first rolling support and the second rolling support are respectively used to roll support both ends of the cylindrical battery cell.

[0023] In one embodiment, both the first rolling support and the second rolling support include two side-by-side rolling support columns that are capable of rolling.

[0024] In one embodiment, a lifting mechanism is further included, and the support mechanism is disposed on the lifting mechanism and is positioned opposite to the adhesive applicator.

[0025] In one embodiment, the lifting mechanism includes a base plate, a first slide rail, a first slider, a lifting arm, and a lifting drive component. The first slide rail is disposed on the base plate, the first slider is disposed on the lifting arm, the first slider is slidably engaged with the first slide rail, the lifting drive component is connected to the lifting arm, and the support mechanism is disposed on the lifting arm.

[0026] In one embodiment, the lifting mechanism further includes a slide block, a second slide rail, and a second slider. The first slider is disposed on the slide block, the second slide rail is disposed on the side of the slide block away from the first slider, the second slider is disposed on the lifting arm, and the second slider slides in cooperation with the second slide rail.

[0027] In one embodiment, the lifting mechanism further includes a first limiting member and a second limiting member. The first limiting member is disposed on the first slide rail and located at the end of the slide block near the support mechanism to limit the end of the slide block near the support mechanism. The second limiting member is disposed on the second slide rail and located at the end of the lifting arm away from the support mechanism to limit the end of the lifting arm away from the support mechanism.

[0028] In one embodiment, a positioning mechanism is further included, comprising a first positioning member and a second positioning member arranged at intervals, the arrangement direction of the first positioning member and the second positioning member being parallel to the rotating shaft of the adhesive applicator, and the spacing between the first positioning member and the second positioning member being adjustable so as to abut against the two ends of the cylindrical battery cell respectively.

[0029] In one embodiment, the first positioning member includes a rotatable first rotating abutment block, and the second positioning member includes a rotatable second rotating abutment block, wherein the first rotating abutment block and the second rotating abutment block are respectively used to abut against both ends of the cylindrical battery cell.

[0030] In one embodiment, the positioning mechanism further includes a first positioning drive and / or a second positioning drive, wherein the first positioning drive is connected to the first positioning member to drive the first positioning member to move toward or away from the second positioning member, and the second positioning drive is connected to the second positioning member to drive the second positioning member to move toward or away from the first positioning member.

[0031] In one embodiment, the positioning mechanism further includes a first transmission member, which includes a first transmission segment and a second transmission segment. The first transmission segment includes a driving wheel disposed on the first positioning drive member, a driven wheel disposed on the second transmission segment, and a synchronous belt connecting the driving wheel and the driven wheel. The end of the second transmission segment away from the driven wheel is connected to the first positioning member. The second transmission segment is used to convert the rotational motion of the driven wheel into linear motion to drive the first positioning member to move toward or away from the second positioning member.

[0032] In one embodiment, the cell bonding device further includes a lifting mechanism, the lifting mechanism includes a base plate and a lifting arm movably disposed on the base plate, the support mechanism is disposed on the lifting arm, and the first positioning member and the second positioning member are both disposed on the lifting arm;

[0033] The positioning mechanism further includes a first transmission member, the first positioning drive member being disposed on the base plate, the first transmission member connecting the first positioning drive member and the first positioning member, wherein, in the lifting direction of the lifting arm, the first positioning member and the first transmission member are detachably connected; and / or

[0034] The positioning mechanism further includes a second transmission component, the second positioning drive component is disposed on the lifting arm, and the second transmission component connects the second positioning drive component and the second positioning component; and / or

[0035] The first positioning drive component includes a motor, and the second positioning drive component includes a cylinder.

[0036] The present invention also provides a battery cell adhesive bonding device, comprising:

[0037] The aforementioned battery cell adhesive bonding device; and

[0038] A battery cell conveying device includes a battery cell conveying mechanism and a battery cell frame for placing cylindrical battery cells. There are multiple battery cell frames, which are arranged at intervals along the conveying direction on the battery cell conveying mechanism. When a battery cell frame is located between the adhesive application mechanism and the support mechanism, the support mechanism can move toward or away from the adhesive application mechanism to press the cylindrical battery cell on the battery cell frame against the adhesive application mechanism.

[0039] When applying adhesive using the above-described battery cell adhesive applicator, the roll of adhesive tape can be first mounted on the unwinding mechanism, then the end of the roll of adhesive tape can be fixed on the adhesive applicator. The adhesive applicator can then rotate, causing the unwound adhesive tape to be fixed onto the adhesive applicator. Next, a cutting mechanism can be used to cut the adhesive tape on the adhesive applicator. Then, the cylindrical battery cell on the support mechanism can be brought into contact with the adhesive applicator. This allows the cut adhesive tape (located on the adhesive applicator) to be applied to the outer circumference of the cylindrical battery cell. In some embodiments, the rotation direction of the cylindrical battery cell can be controlled to be opposite to the rotation direction of the adhesive applicator, thereby causing the cut adhesive tape (adhesive strip) to be applied to the outer circumference of the cylindrical battery cell.

[0040] In the aforementioned battery cell adhesive applicator, the adhesive applicator can hold the adhesive tape unwound from the unwinding mechanism and can rotate. This allows the unwinding mechanism and the adhesive applicator to work together to unwrap the tape (pull the tape), enabling the cutting mechanism to cut the tape into an adhesive strip on the adhesive applicator. The resulting adhesive strip is positioned on the adhesive applicator and does not require a transfer mechanism to be transferred back to it for application. Therefore, this battery cell adhesive applicator does not require an additional tape-pulling mechanism, which not only reduces the cost but also the size of the device, resulting in a smaller footprint. Furthermore, the adhesive strip can be applied without transfer, reducing the number of steps and improving efficiency. Therefore, the aforementioned battery cell adhesive applicator features low cost, small footprint, and high application efficiency. Attached Figure Description

[0054] like Figure 1 As shown, an embodiment of the present invention provides a battery cell bonding apparatus 10. The battery cell bonding apparatus 10 includes a battery cell bonding device 12 and a battery cell conveying device 14. The battery cell conveying device 14 conveys cylindrical battery cells 20 to the battery cell bonding device 12. The battery cell bonding device 12 retrieves the cylindrical battery cells 20 from the battery cell conveying device 14, applies adhesive to the cylindrical battery cells 20, and then places the bonded cylindrical battery cells 20 onto the battery cell conveying device 14. Simultaneously conveying the bonded cylindrical battery cells 20, the battery cell conveying device 14 can also convey the next cylindrical battery cell 20 to the battery cell bonding device 12 for the next bonding operation. Thus, the battery cell bonding apparatus 10 can continuously apply adhesive, making it highly suitable for battery production.

[0055] like Figures 1-5 As shown, an embodiment of the present invention provides a battery cell adhesive applicator 12. The battery cell adhesive applicator 12 includes an unwinding mechanism 100, an adhesive applicator 200, a cutting mechanism 300, and a supporting mechanism 400. The unwinding mechanism 100 includes a method for unwinding adhesive tape 30 onto the adhesive applicator 200. The adhesive applicator 200 can hold the adhesive tape 30 unwound from the unwinding mechanism 100 onto the adhesive applicator 200. The cutting mechanism 300 is used to cut the adhesive tape 30 on the adhesive applicator 200. The supporting mechanism 400 is used to support the cylindrical battery cell 20. The supporting mechanism 400 is also used to abut the cylindrical battery cell 20 located on the supporting mechanism 400 against the adhesive applicator 200, so that the cut adhesive tape 30 is applied to the outer periphery of the cylindrical battery cell 20.

[0056] When applying adhesive using the aforementioned battery cell adhesive applicator 12, the rolled adhesive tape 30 can be first mounted on the unwinding mechanism 100, and then the end of the rolled adhesive tape 30 can be fixed on the adhesive applicator 200. The adhesive applicator 200 can then rotate, causing the unwound adhesive tape 30 to be fixed on the adhesive applicator 200. The cutting mechanism 300 can then cut the adhesive tape 30 on the adhesive applicator 200. Next, the cylindrical battery cell 20 on the support mechanism 400 can be brought into contact with the adhesive applicator 200, allowing the cut adhesive tape 30 (located on the adhesive applicator 200) to be applied to the outer periphery of the cylindrical battery cell 20. In some embodiments, the rotation direction of the cylindrical battery cell 20 can be controlled to be opposite to the rotation direction of the adhesive applicator 200, thereby allowing the cut adhesive tape (adhesive strip) to be applied to the outer periphery of the cylindrical battery cell 20.

[0057] In the aforementioned battery cell adhesive applicator 12, the adhesive applicator 200 can fix the adhesive tape 30 unwound from the unwinding mechanism 100 onto the adhesive applicator 200. The adhesive applicator 200 is rotatable, allowing the unwinding mechanism 100 and the adhesive applicator 200 to cooperate in unwinding the adhesive tape 30 (pulling the tape). This enables the cutting mechanism 300 to cut the adhesive tape 30 onto the adhesive applicator 200 to form an adhesive strip. The formed adhesive strip is located on the adhesive applicator 200 and does not require a transfer mechanism to transfer it back to the adhesive applicator 200 for adhesive application. Therefore, the aforementioned battery cell adhesive applicator 12 does not require an additional pulling mechanism, which not only reduces the cost of the battery cell adhesive applicator 12 but also reduces its size, resulting in a smaller footprint. Furthermore, the formed adhesive strip can be applied without transfer, reducing adhesive application steps and improving efficiency. Therefore, the aforementioned battery cell adhesive applicator 12 features low cost, small footprint, and high adhesive application efficiency.

[0058] In this embodiment, the support mechanism 400 provides rolling support for the cylindrical battery cell 20. When the cylindrical battery cell 20 comes into contact with the adhesive applicator 200, the rotation of the adhesive applicator 200 causes the cylindrical battery cell 20 to rotate in the opposite direction, allowing the adhesive tape to adhere to the outer circumference of the cylindrical battery cell 20. That is, in this embodiment, the rotation of the adhesive applicator 200 causes the cylindrical battery cell 20 to rotate in the opposite direction, thus achieving a rotation direction opposite to that of the adhesive applicator 200. It is understood that in other embodiments, the rotation of the cylindrical battery cell 20 can also cause the adhesive applicator 200 to rotate in the opposite direction, thereby achieving a rotation direction opposite to that of the adhesive applicator 200.

[0059] In this embodiment, the unwinding mechanism 100 includes a main unwinding component 110. The main unwinding component 110 can be an unwinding roller. This greatly facilitates the unwinding of the tape 30. It is understood that in other embodiments, a disc can be used instead of an unwinding roller.

[0060] In this embodiment, the unwinding mechanism 100 further includes an auxiliary unwinding component 120 located between the adhesive application mechanism 200 and the main unwinding component 110. The auxiliary unwinding component 120 assists in unwinding the adhesive tape 30. The number of auxiliary unwinding components 120 is greater than or equal to one. The auxiliary unwinding component 120 can be a guide roller. This facilitates the unwinding mechanism 100 in unwinding the adhesive tape 30. It is understood that in other embodiments, the auxiliary unwinding component 120 may be omitted.

[0061] In this embodiment, the adhesive application mechanism 200 includes an adhesive application roller. This makes adhesive application easier. It is understood that in other embodiments, a disc may be used instead of the adhesive application roller.

[0062] In this embodiment, the unwinding mechanism 100 unwinds the adhesive tape 30 at the adhesive receiving station 200a. The cutting mechanism 300 cuts the adhesive tape 30 at the adhesive receiving station 200a to form an adhesive strip. The cylindrical battery cell 20 located on the support mechanism 400 abuts against the adhesive application mechanism 200 at the adhesive application station 200b. In the circumferential direction of the adhesive application mechanism 200, the cutting station 200c is located between the adhesive receiving station 200a and the adhesive application station 200b. Thus, when the rotation direction of the adhesive application mechanism 200 is the same as the arrangement direction of the adhesive receiving station 200a, the cutting station 200c, and the adhesive application station 200b, the adhesive tape 30 can be controlled to be located only in the area defined by the adhesive receiving station 200a, the cutting station 200c, and the adhesive application station 200b of the adhesive application mechanism 200. Specifically, in Figure 1 In the illustrated embodiment, the adhesive applicator 200 rotates clockwise, and the adhesive tape 30 is located only on the right half of the adhesive applicator 200. Furthermore, the simultaneous installation of the adhesive receiving station 200a, the adhesive cutting station 200c, and the adhesive applicator 200b allows for simultaneous unwinding of the adhesive tape 30, cutting, and applicating, eliminating the need for sequential operations and resulting in higher applicability.

[0063] It is understood that in other embodiments, the glue cutting station 200c and the glue application station 200b can be combined into one, that is, the glue cutting station 200c and the glue application station 200b can be the same station, where glue can be cut first and then glued. Specifically, in Figure 1In the illustrated embodiment, when both the cutting station 200c and the applying station 200b correspond to the lowest point of the applying mechanism 200, the applying mechanism 200 can first rotate three-quarters of a turn clockwise, so that the end of the tape 30 on the applying mechanism 200 moves from the highest point of the applying mechanism 200 to the leftmost point of the applying mechanism 200. Then, the cutting mechanism 300 cuts the tape 30 at the lowest point of the applying mechanism 200, obtaining a strip of tape with a length of one-quarter of the circumference of the applying mechanism 200. Next, the applying mechanism 200 can rotate one-quarter of a turn counterclockwise, so that one end of the strip is located at the lowest point of the applying mechanism 200 and the other end is located at the rightmost point of the applying mechanism 200. Then, the applying mechanism 200 is controlled to rotate clockwise, while the cylindrical battery cell 20 on the support mechanism 400 is controlled to abut against the applying mechanism 200. The rotation of the applying mechanism 200 drives the cylindrical battery cell 20 to rotate counterclockwise so that the strip of tape is applied to the outer circumference of the cylindrical battery cell 20, completing the first application.

[0064] After the first application of adhesive is completed, the end of the tape 30 on the adhesive application mechanism 200 is located at the lowest point of the adhesive application mechanism 200. The adhesive applicator 200 continues to rotate clockwise, completing a quarter turn, so that the end of the adhesive tape 30 on the adhesive applicator 200 is at the leftmost point of the adhesive applicator 200. During this process, the cylindrical battery cell 20 after adhesive application can be separated from the adhesive applicator 200. Then, the cutting mechanism 300 cuts the adhesive tape 30 again at the lowest point of the adhesive applicator 200, obtaining an adhesive strip with a length of one-quarter of the circumference of the adhesive applicator 200. Next, the adhesive applicator 200 can rotate counterclockwise by one-quarter turn, so that one end of the adhesive strip is at the lowest point of the adhesive applicator 200 and the other end is at the rightmost point of the adhesive applicator 200. Then, the adhesive applicator 200 is controlled to rotate clockwise, while the next cylindrical battery cell 20 on the support mechanism 400 is controlled to abut against the adhesive applicator 200. The rotation of the adhesive applicator 200 drives the cylindrical battery cell 20 to rotate counterclockwise, so that the adhesive strip is applied to the outer circumference of the cylindrical battery cell 20, completing the second adhesive application. Repeating the above second adhesive application can achieve continuous adhesive application.

[0065] In this embodiment, the adhesive applicator 200 includes a vacuum adsorption section 210. The vacuum adsorption section 210 can fix the tape 30 by vacuum adsorption. This makes it very convenient for the adhesive applicator 200 to fix the tape 30. Specifically, in this embodiment, the adhesive side of the tape 30 is fixed to the adhesive applicator 200, and the adhesive side of the tape 300 is exposed on the adhesive applicator 200. It can be understood that in other embodiments, when the tape 30 is a double-sided adhesive tape with one side having high adhesion and the other side having low adhesion, the tape 30 is fixed to the adhesive applicator 200 with the side having low adhesion, and the side with high adhesion is exposed on the adhesive applicator 200. In this case, the vacuum adsorption section 210 can be omitted.

[0066] In this embodiment, the adhesive applicator 200 has a cavity. The vacuum adsorption unit 210 has an adsorption hole 212. The adsorption hole 212 is located on the outer peripheral wall of the adhesive applicator 200 and communicates with the cavity. Thus, after the cavity is connected to an external vacuum device, a vacuum is created by the external vacuum device, and the vacuum adsorption unit 210 can vacuum-adsorb the adhesive tape 30.

[0067] In this embodiment, the vacuum adsorption unit 210 extends circumferentially around the adhesive applicator 200. Thus, the adhesive applicator 200 can adsorb and fix the tape 30 along its entire circumference, facilitating continuous adhesive application and allowing the adhesive applicator 200 to continuously vacuum-adsorb the tape 30 without changing its rotation direction.

[0068] Specifically, with Figure 1 In the illustrated embodiment, the length of the adhesive strip is one-quarter of the circumference of the adhesive application mechanism 200. This length of adhesive strip perfectly matches the adhesive application length required for a cylindrical battery cell 20. Thus, when the adhesive application mechanism 200 rotates clockwise (pulling the adhesive), causing the end of the tape 30 unwound from the adhesive application mechanism 200 to reach the adhesive application station 200b (corresponding to the lowest point of the adhesive application mechanism 200), the cutting mechanism 300 can cut the tape 30 on the adhesive application mechanism 200 at the cutting station 200c (corresponding to the rightmost point of the adhesive application mechanism 200) to obtain an adhesive strip (cutting the adhesive). Simultaneously, the cylindrical battery cell 20 on the support mechanism 400 can be controlled to abut against the adhesive application mechanism 200 at the adhesive application station 200b. The rotation of the adhesive application mechanism 200 drives the cylindrical battery cell 20 to rotate in the opposite direction, so that the adhesive strip is applied to the outer circumference of the cylindrical battery cell 20, completing the first adhesive application. After the first application of adhesive, the new end of the tape 30 is positioned at the application station 200b. At this point, the application mechanism 200 can be stopped from rotating. After the cylindrical battery cell 20 with adhesive is separated from the application mechanism 200, the application mechanism 200 can be rotated clockwise again. Simultaneously, the cutting mechanism 300 can cut the tape 30 on the application mechanism 200 again to obtain an adhesive strip (cut tape). At the same time, the next cylindrical battery cell 20 on the support mechanism 400 can be brought into contact with the application mechanism 200 for the second application of adhesive. By repeating the second application, continuous application of adhesive can be achieved. During the cycle, the rotation direction of the application mechanism 200 does not need to be changed and remains clockwise.

[0069] It is understood that in other embodiments, the length of the vacuum adsorption section 210 may also be less than the circumference of the adhesive applicator 200. For example, when the length of the vacuum adsorption section 210 is greater than the sum of the lengths of the two adhesive strips (it can be the sum of the lengths of three adhesive strips; in the initial position, one end of the vacuum adsorption section 210 is located at the adhesive receiving station 200a, and the other end is located at the adhesive cutting station 200c after passing the leftmost point of the adhesive applicator 200 and the adhesive applicator station 200b), the adhesive applicator 200 can be controlled to rotate clockwise first, forming two adhesive strips with adjacent ends on the adhesive applicator 200, and making the beginning and end (middle) of the two adhesive strips located at the adhesive applicator station 200b (at this time, the vacuum adsorption section 210...). One end of 210 is located at the glue-receiving station 200a, and the other end, after passing through the glue-cutting station 200c and the glue-applying station 200b, is located at the leftmost point of the glue-applying mechanism 200. Then, the glue-applying mechanism 200 can be reversed, so that the beginning and end (middle) of the two glue strips are located at the glue-cutting station 200c, thereby placing the other end (front end) of the first glue strip at the glue-applying station 200b. Next, the glue-applying mechanism 200 is controlled to rotate clockwise, while simultaneously controlling the cylindrical battery cell 20 on the support mechanism 400 to abut against the glue-applying mechanism 200 for the first glue application. After the first glue application is completed, the glue-applying mechanism 200 can be stopped rotating. After the glued cylindrical battery cell 20 separates from the glue-applying mechanism 200, the glue-applying mechanism 200 can be controlled to rotate clockwise again, while simultaneously controlling the next cylindrical battery cell 20 on the support mechanism 400 to abut against the glue-applying mechanism 200 for the second glue application. After the second application of adhesive, the adhesive application mechanism 200 can be reversed to its initial position, and then the two applications can be repeated. This cycle can be repeated to achieve continuous adhesive application, but the rotation direction of the adhesive application mechanism 200 needs to be changed during the cycle.

[0070] In this embodiment, the adhesive applicator 200 has a cutter clearance groove 220. The vacuum suction unit 210 disconnects at the cutter clearance groove 220. The cutting mechanism 300 cuts the tape 30 at the cutter clearance groove 220. Thus, when the cutting mechanism 300 uses a solid cutter 310 to cut the tape 30, the cutter clearance groove 220 can avoid the solid cutter 310 moving towards the adhesive applicator 200 and acting on the tape 30, which greatly facilitates the solid cutter 310 cutting the tape 30 on the adhesive applicator 200. It can be understood that in other embodiments, when the cutting mechanism 300 does not use a solid cutter 310 to cut the tape 30, but uses a non-contact cutter such as a laser cutter, the cutter clearance groove 220 can be omitted.

[0071] In this embodiment, the cutting mechanism 300 further includes a cutter drive 320. The cutter drive 320 is connected to the physical cutter 310. The cutter drive 320 is used to control the movement of the physical cutter 310 toward or away from the adhesive application mechanism 200. Specifically, in this embodiment, the cutter drive 320 includes a cylinder.

[0072] In this embodiment, there are multiple (two or more) cutter clearance grooves 220. These multiple cutter clearance grooves 220 are arranged at intervals along the circumference of the adhesive application mechanism 200. This facilitates continuous adhesive application. It is understood that in other embodiments, there may be only one cutter clearance groove 220. Specifically, with... Figure 1 Taking the illustrated embodiment as an example, firstly, the tape 30 is unwound at the adhesive receiving station 200a (corresponding to the highest point of the adhesive applicator 200). At this time, the cutter clearance groove 220 is set corresponding to the leftmost point of the adhesive applicator 200. Then, after the adhesive applicator 200 rotates clockwise (pulls the tape) half a turn, when the end of the tape 30 unwound from the adhesive applicator 200 reaches the adhesive applicator station 200b, the cutter clearance groove 220 moves to the cutting station 200c of the adhesive applicator 200. At this time, the cutting mechanism 300 can cut the tape applicator. The tape 30 on the structure 200 is used to obtain a strip of adhesive (cutting adhesive). At the same time, the cylindrical battery cell 20 on the support mechanism 400 can be controlled to abut against the adhesive application mechanism 200. The rotation of the adhesive application mechanism 200 drives the cylindrical battery cell 20 to rotate in the opposite direction so that the adhesive strip is applied to the outer periphery of the cylindrical battery cell 20, thus completing the adhesive application. At this time, the cutter clearance groove 220 is located at the adhesive application station 200b. At the same time, the unwinding mechanism 100 and the adhesive application mechanism 200 can be wound in opposite directions. After the cutter clearance groove 220 is set to correspond to the leftmost point of the adhesive application mechanism 200 again, the above adhesive application process is repeated.

[0073] In this embodiment, the multiple cutter clearance grooves 220 are arranged at equal intervals along the circumference of the adhesive applicator 200. This not only facilitates continuous adhesive application but also ensures that the adhesive strip applied each time is of consistent length without requiring the adhesive applicator 200 to change its rotation direction. It is understood that in other embodiments, the multiple cutter clearance grooves 220 may be arranged at unequal intervals along the circumference of the adhesive applicator 200.

[0074] In this embodiment, the cutting mechanism 300 and the supporting mechanism 400 are respectively positioned directly opposite to the two adjacent cutter clearance grooves 220. Thus, only one cutting mechanism 300 is needed to ensure that the length of the adhesive strip applied each time is consistent. It is understood that in other embodiments, multiple cutting mechanisms 300 may be provided.

[0075] In this embodiment, there are four cutting blade clearance slots 220. Thus, an adhesive application station 200b can be provided below the adhesive application mechanism 200, an adhesive receiving station 200a can be provided above the adhesive application mechanism 200, and an adhesive cutting station 200c can be provided between the adhesive application station 200b and the adhesive receiving station 200a. It is understood that in other embodiments, there may be two or three, or five or more, cutting blade clearance slots 220.

[0076] In this embodiment, the adhesive-feeding station 200a and the adhesive-applying station 200b correspond to the two ends of half the circumference of the adhesive-applying mechanism 200, respectively. That is, the circumferential distance between the adhesive-feeding station 200a and the adhesive-applying station 200b of the adhesive-applying mechanism 200 matches half the circumference of the adhesive-applying mechanism 200. Thus, when the rotation direction of the adhesive-applying mechanism 200 is the same as the arrangement direction of the adhesive-feeding station 200a, the adhesive-cutting station 200c, and the adhesive-applying station 200b, the tape 30 can be controlled to be located only on half of the adhesive-applying mechanism 200, which greatly facilitates unwinding the tape 30, cutting the tape, and applying the tape. Specifically, in Figure 1 In the illustrated embodiment, the adhesive applicator 200 rotates clockwise, and the tape 30 is applied only to the right half of the adhesive applicator 200. It can be understood that in other embodiments, the distance between the adhesive receiving station 200a and the adhesive applying station 200b in the circumferential direction of the adhesive applicator 200 can also be greater than half the circumference of the adhesive applicator 200. For example, the distance between the adhesive receiving station 200a and the adhesive applying station 200b can also match three-quarters of the circumference of the adhesive applicator 200.

[0077] In this embodiment, the adhesive application station 200a corresponds to the upper part of the adhesive application mechanism 200 (corresponding to the highest point of the adhesive application mechanism 200), and the adhesive application station 200b corresponds to the lower part of the adhesive application mechanism 200 (corresponding to the lowest point of the adhesive application mechanism 200). This facilitates the unwinding of the tape 30, cutting of the tape, and application of the tape. It is understood that in other embodiments, the specific orientation of the stations is not limited to the above orientation and can be adjusted accordingly based on the actual application.

[0078] In this embodiment, the cutting station 200c corresponds precisely to the center of half the circumference of the adhesive application mechanism 200 (corresponding to the rightmost or leftmost point of the adhesive application mechanism 200). That is, in this embodiment, the distance between the cutting station 200c and the receiving station 200a in the circumferential direction of the adhesive application mechanism 200 matches one-quarter of the circumference of the adhesive application mechanism 200, and the distance between the cutting station 200c and the adhesive application station 200b in the circumferential direction of the adhesive application mechanism 200 also matches one-quarter of the circumference of the adhesive application mechanism 200. This facilitates not only unwinding the tape 30, cutting, and applying the tape, but also the formation of an adhesive strip with a length one-quarter of the circumference of the adhesive application mechanism 200. It is understood that in other embodiments, when the required length of the adhesive strip changes, the distance between the cutting station 200c and the adhesive application station 200b can be changed accordingly.

[0079] In this embodiment, the glue-receiving station 200a, the glue-cutting station 200c, and the glue-applying station 200b are all corresponding to the cutting knife clearance groove 220.

[0080] In this embodiment, the support mechanism 400 includes a first rolling support member 410 and a second rolling support member 420 arranged at intervals. The arrangement direction of the first rolling support member 410 and the second rolling support member 420 is parallel to the rotation axis of the adhesive applicator 200. The first rolling support member 410 and the second rolling support member 420 are respectively used to roll and support the two ends of the cylindrical battery cell 20. In this way, the contact area between the cylindrical battery cell 20 and the support mechanism 400 can be reduced, the friction can be reduced, and thus it is easier for the support mechanism 400 to roll and support the cylindrical battery cell 20.

[0081] Furthermore, when the aforementioned cell adhesive applicator 12 is applied to the cell adhesive applicator 10 to construct a cell production line, the cell conveying mechanism 14a of the cell conveying device 14 can be used to convey the cylindrical cell 20. The cylindrical cell 20 can be placed on the cell frame 14b of the cell conveying device 14, while the two ends of the cylindrical cell 20 can be located outside the cell frame 14b and suspended in the air. When a cylindrical cell 20 is conveyed between the adhesive applicator 200 and the support mechanism 400, the first rolling support member 410 and the second rolling support member 420, which are arranged at intervals, can first support the two ends of the cylindrical cell 20 during their movement toward the adhesive applicator 200, and then separate the cylindrical cell 20 from the cell frame 14b (that is, take the cylindrical cell 20 from the cell frame 14b), and finally make the cylindrical cell 20 located on the support mechanism 400 come into contact with the adhesive applicator 200, thereby enabling adhesive application. After the adhesive is applied, the first rolling support 410 and the second rolling support 420, which are arranged at intervals, can place the coated cylindrical battery cell 20 on the battery cell frame 14b as they move away from the adhesive application mechanism 200. While the battery cell conveying mechanism 14b is conveying the coated cylindrical battery cell 20, it can also convey the next cylindrical battery cell 20 between the adhesive application mechanism 200 and the support mechanism 400 to prepare for the above-mentioned adhesive application operation on the next cylindrical battery cell 20.

[0082] Because the first rolling support 410 and the second rolling support 420 are arranged at intervals, the support mechanism 400 can pick up and place cylindrical battery cells 20 on the battery cell holder 14b without interfering with the battery cell holder 14b. It is understood that in other embodiments, when a robotic arm or similar means is used to pick up and place cylindrical battery cells 20 on the support mechanism 400, the first rolling support 410 and the second rolling support 420 may be connected as a continuous whole without any gap.

[0083] In this embodiment, both the first rolling support 410 and the second rolling support 420 include two side-by-side rolling support columns 412 that are capable of rolling. Thus, the support mechanism 400 not only facilitates the rolling support of the cylindrical battery cell 20 but is also very easy to manufacture. It is understood that in other embodiments, both the first rolling support 410 and the second rolling support 420 may also be arc-shaped structures with smooth inner walls.

[0084] In this embodiment, the two rolling support columns 412 arranged side by side are spaced apart in the arrangement direction. This reduces the requirement for the outer diameter of the rolling support columns 412, allowing for the rolling support columns 412 with smaller outer diameters to support the cylindrical battery cell 20 with a larger outer diameter. It is understood that in other embodiments, the two rolling support columns 412 arranged side by side may also be in contact in the arrangement direction.

[0085] In this embodiment, the battery cell adhesive applicator 12 further includes a lifting mechanism 500. A support mechanism 400 is mounted on the lifting mechanism 500 and directly opposite the adhesive applicator 200. Thus, when the cylindrical battery cell 20 on the support mechanism 400 comes into contact with the adhesive applicator 200, the lifting mechanism 500 can control the support mechanism 400 to move towards the adhesive applicator 200. It is understood that in other embodiments, this can also be achieved by controlling the adhesive applicator 200 to move towards the support mechanism 400, or by controlling both the support mechanism 400 and the adhesive applicator 200 to move towards the support mechanism 400.

[0086] In this embodiment, the lifting mechanism 500 includes a base plate 510, a first slide rail 520, a first slider 530, a lifting arm 540, and a lifting drive member 550. The first slide rail 520 is disposed on the base plate 510. The first slider 530 is disposed on the lifting arm 540. The first slider 530 is slidably engaged with the first slide rail 520. The lifting drive member 550 is connected to the lifting arm 540 (the lifting drive member 550 can be directly or indirectly disposed on the base plate 510, or it can be disposed on the frame of the battery cell adhesive applicator 12, wherein the frame is used to support the various mechanisms of the battery cell adhesive applicator 12). A support mechanism 400 is disposed on the lifting arm 540. The slidable engagement between the first slider 530 and the first slide rail 520 makes the lifting movement of the support mechanism 400 disposed on the lifting arm 540 smoother and more precise. It can be understood that in other embodiments, the first slide rail 520 and the first slider 530 may be omitted.

[0087] In this embodiment, the lifting mechanism 500 further includes a slide block 560, a second slide rail 570, and a second slider 580. A first slider 530 is disposed on the slide block 560. The second slide rail 570 is disposed on the side of the slide block 560 away from the first slider 530. The second slider 580 is disposed on the lifting arm 540. The second slider 580 and the second slide rail 570 are in sliding engagement. By providing a sliding engagement between the first slider 530 and the first slide rail 520, and the second slider 580 and the second slide rail 570, a two-layer sliding structure is adopted, which can prevent the support mechanism 400 from rising too quickly and impacting the cylindrical battery cell 20. It is understood that in other embodiments, only a single-layer sliding structure may be used.

[0088] In this embodiment, the lifting mechanism 500 further includes a first limiting member 590a and a second limiting member 590b. The first limiting member 590a is disposed on the first slide rail 520 and located at the end of the slide block 560 near the support mechanism 400, thereby limiting the end of the slide block 560 near the support mechanism 400. The second limiting member 590b is disposed on the second slide rail 570 and located at the end of the lifting arm 540 away from the support mechanism 400, thereby limiting the end of the lifting arm 540 away from the support mechanism 400. Thus, the first limiting member 590a cooperates with the slide block 560 to limit the maximum distance the lifting arm 540 can move toward the adhesive applicator 200, while the second limiting member 590b cooperates with the lifting arm 540 to limit the maximum distance the lifting arm 540 can move away from the adhesive applicator 200, thereby ensuring that the lifting of the lifting arm 540 is within a preset range.

[0089] Furthermore, the second limiting member 590b is located at the end of the lifting arm 540 away from the support mechanism 400. Conversely, if the second limiting member 590b is located at the end of the lifting arm 540 closer to the support mechanism 400, interference between the second limiting member 590b and the support mechanism 400 can be avoided. The first limiting member 590a is located at one end of the slide 560, and the second limiting member 590b is located at one end of the lifting arm 540. Conversely, if the first limiting member 590a and the second limiting member 590b are located at opposite ends of the slide 560 or opposite ends of the lifting arm 540, the installation space of the lifting mechanism 500 can be fully utilized, avoiding interference between the limiting members and other components. It is understood that in other embodiments, the above-described other solutions are also acceptable when the interference problem can be overcome.

[0090] In this embodiment, the battery cell adhesive applicator 12 further includes a positioning mechanism 600. The positioning mechanism 600 includes a first positioning member 610 and a second positioning member 620 arranged at intervals. The arrangement direction of the first positioning member 610 and the second positioning member 620 is parallel to the rotation axis of the adhesive applicator 200, and the spacing between the first positioning member 610 and the second positioning member 620 is adjustable to abut against both ends of the cylindrical battery cell 20 respectively. This facilitates the positioning of the cylindrical battery cell 20, ensuring that the adhesive tape 30 is applied to the correct position.

[0091] Specifically, during positioning, the position of the first positioning member 610 can be determined first, so that the first positioning member 610 is in a preset position. Then, the second positioning member 620 is controlled to move toward the first positioning member 610, pushing the cylindrical battery cell 20, and finally bringing the cylindrical battery cell 20 abutting against the first positioning member 610, thereby achieving the positioning of the cylindrical battery cell 20. That is, in this embodiment, the first positioning member 610 is the main positioning member, and the second positioning member 620 is the auxiliary positioning member. It should be noted that when determining the position of the first positioning member 610, the first positioning member 610 can be controlled to move toward or away from the second positioning member 620 so that the first positioning member 610 is in a preset position. At this time, the first positioning member 610 can move toward or away from the second positioning member 620. When determining the position of the first positioning member 610, the first positioning member 610 can also be directly installed in the preset position. In this case, the first positioning member 610 may not be able to move toward or away from the second positioning member 620.

[0092] In this embodiment, the first positioning member 610 includes a rotatable first rotating abutment block 612. The second positioning member 620 includes a rotatable second rotating abutment block 622. The first rotating abutment block 612 and the second rotating abutment block 622 are respectively used to abut against both ends of the cylindrical battery cell 20. Thus, since the first rotating abutment block 612 and the second rotating abutment block 622 abut against the cylindrical battery cell 20 can roll synchronously with the cylindrical battery cell 20, after positioning, the first positioning member 610 and the second positioning member 620 do not release the cylindrical battery cell 20, and the cylindrical battery cell 20 can also be rolled and glued. Therefore, during the rolling and glued process, the first positioning member 610 and the second positioning member 620 can also position the cylindrical battery cell 20, thereby further ensuring that the tape 30 is applied to the correct position. It is understood that in other embodiments, the first rotating abutment block 612 and the second rotating abutment block 622 may also be omitted. In this case, before rolling the adhesive, the first positioning member 610 and the second positioning member 620 can be controlled to release the cylindrical battery cell 20.

[0093] In this embodiment, both the first rotating abutment block 612 and the second rotating abutment block 622 are bearings. This facilitates synchronous rolling with the cylindrical battery cell 20. It is understood that in other embodiments, the first rotating abutment block 612 and the second rotating abutment block 622 may also be other components capable of synchronous rolling with the cylindrical battery cell 20.

[0094] In this embodiment, the positioning mechanism 600 further includes a first positioning drive 630 and a second positioning drive 640. The first positioning drive 630 is connected to the first positioning member 610 to drive the first positioning member 610 to move toward or away from the second positioning member 620. The second positioning drive 640 is connected to the second positioning member 620 to drive the second positioning member 620 to move toward or away from the first positioning member 610. The simultaneous provision of both the first positioning drive 630 and the second positioning drive 640 facilitates positioning. It is understood that in other embodiments, the positioning mechanism 600 may also include only the first positioning drive 630 or the second positioning drive 640. In this case, the second positioning member 620 cannot move toward or away from the first positioning member 610, or the first positioning member 610 cannot move toward or away from the second positioning member 620.

[0095] In this embodiment, the positioning mechanism 600 further includes a first transmission member 650. The first transmission member 650 includes a first transmission segment 652 and a second transmission segment 654. The first transmission segment 652 includes a driving wheel 652a mounted on the motor, a driven wheel 652b mounted on the second transmission segment 654, and a synchronous belt 652c connecting the driving wheel 652a and the driven wheel 652b. The end of the second transmission segment 654 away from the driven wheel 652b is connected to the first positioning member 610. The second transmission segment 654 is used to convert the rotational motion of the driven wheel 652b into linear motion, so as to drive the first positioning member 610 to move toward or away from the second positioning member 620. The first positioning member 610 is the main positioning member, and the driving positioning member uses the synchronous belt 652c for transmission, which can make the positioning very accurate.

[0096] In this embodiment, the first positioning drive 630 includes a motor. The motor and the timing belt 652c can work well together. It is understood that in other embodiments, the first positioning drive 630 may also use other power drive components.

[0097] In this embodiment, the second transmission segment 654 includes a transmission rod 645a, a gear, and a rack. A driven wheel 652b is fitted onto one end of the transmission rod 645a. The gear is fitted onto the other end of the transmission rod 645a. One end of the rack meshes with the gear, and the other end is connected to the first positioning member 610. This facilitates the conversion of the rotational motion of the driven wheel 652b into linear motion, driving the first positioning member 610 to move towards or away from the second positioning member 620. It is understood that in other embodiments, other structures can be used to convert the rotational motion of the driven wheel 652b into linear motion.

[0098] In this embodiment, both the first positioning member 610 and the second positioning member 620 are disposed on the lifting arm 540. That is, in this embodiment, the first positioning member 610 and the second positioning member 620 can move with the lifting arm 540. It can be understood that in other embodiments, the first positioning member 610 and the second positioning member 620 may not be disposed on the lifting arm 540. In this case, after the support mechanism 400 receives the cylindrical battery cell 20, the first positioning member 610 and the second positioning member 620 can first position the cylindrical battery cell 20. After the positioning is completed, the lifting arm 540 controls the lifting and lowering of the support mechanism 400.

[0099] In this embodiment, the first positioning drive member 630 is disposed on the substrate 510. In the lifting direction of the lifting arm 540, that is, in the arrangement direction of the support mechanism 400 and the adhesive applicator 200, the first positioning member 610 and the first transmission member 650 are detachably connected. Thus, after the support mechanism 400 receives the cylindrical battery cell 20, the first positioning member 610 and the second positioning member 620 can first position the cylindrical battery cell 20. At this time, the first positioning member 610 is connected to the first transmission member 650, and the first positioning drive member 630 can drive the first positioning member 610 to move closer to or away from the second positioning member 620 through the first transmission member 650. After positioning is completed, the lifting arm 540 controls the lifting and lowering of the support mechanism 400 so that the cylindrical battery cell 20 abuts against the adhesive applicator 200. At this time, the first positioning member 610 can follow the lifting and lowering of the support mechanism 400 and separate from the first transmission member 650. During the positioning process described above, components such as the substrate 510 and the first positioning drive member 630 do not move up or down with the support mechanism 400, thereby reducing the requirements on the lifting mechanism 500 and saving energy. It is understood that in other embodiments, the substrate 510 and the first positioning drive member 630 may also move up and down with the support mechanism 400.

[0100] In this embodiment, the second transmission segment 654 has one of a slot and a plug. The first positioning member 610 has the other of a slot and a plug. In the lifting direction of the lifting arm 540, that is, in the arrangement direction of the support mechanism 400 and the adhesive applicator 200, the slot and the plug engage in a plug-in / plug-out manner. This makes it very easy to achieve a separable connection between the first positioning member 610 and the second transmission segment 654 (first transmission member 650).

[0101] In this embodiment, the second positioning drive member 640 is disposed on the lifting arm 540. Thus, both the second positioning member 620 and the second positioning drive member 640 can move up and down with the support mechanism 400, and can be positioned before or after the lifting. Specifically, in this embodiment, the second positioning drive member 640 is a cylinder. That is, in this embodiment, the first positioning drive member 630 and the second positioning drive member 640 are different. It can be understood that in other embodiments, the first positioning drive member 630 and the second positioning drive member 640 can be the same; they can both be cylinders, or they can both be a motor + synchronous belt 652c.

[0102] In this embodiment, the battery cell bonding equipment 10 further includes a battery cell conveying device 14. The battery cell conveying device 14 includes a battery cell conveying mechanism 14a and a battery cell holder 14b for placing cylindrical battery cells 20. Multiple battery cell holders 14b are arranged at intervals along the conveying direction on the battery cell conveying mechanism 14a. When a battery cell holder 14b is located between the bonding mechanism 200 and the support mechanism 400, the support mechanism 400 can move toward or away from the bonding mechanism 200 to press the cylindrical battery cells 20 on the battery cell holder 14b against the bonding mechanism 200. This greatly facilitates continuous bonding.

[0103] like Figure 6 As shown, the present invention also provides an adhesive application method. This adhesive application method includes the following steps:

[0104] Step S710: Control the unwinding mechanism to rotate the unwinding tape and fix the unwound tape on the adhesive applicator.

[0105] Step S720: Cut the tape on the adhesive applicator.

[0106] In step S730, the cylindrical battery cell on the support mechanism is brought into contact with the adhesive application mechanism, and the rotation direction of the adhesive application mechanism is controlled to be opposite to the rotation direction of the cylindrical battery cell, so that the cut adhesive tape is applied to the outer periphery of the cylindrical battery cell.

[0107] In this embodiment, the step of cutting the tape on the adhesive applicator is performed simultaneously with the step of controlling the cylindrical battery cell on the support mechanism to abut against the adhesive applicator.

[0108] The present invention also provides a continuous adhesive application method. This continuous adhesive application method includes multiple adhesive application methods described above. In the above adhesive application method, when the cylindrical battery cell comes into contact with the adhesive application mechanism, the rotation of the adhesive application mechanism drives the cylindrical battery cell to rotate in the opposite direction, so that the cut adhesive tape is applied to the outer periphery of the cylindrical battery cell.

[0109] The following steps are also included between two consecutive adhesive application methods:

[0110] Control the adhesive application mechanism to stop rotating; and

[0111] The cylindrical battery cell is separated from the adhesive application mechanism after the adhesive is applied.

[0112] In this embodiment, the step of controlling the adhesive application mechanism to stop rotating is performed simultaneously with the step of controlling the cylindrical battery cell after adhesive application to separate from the adhesive application mechanism.

[0113] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0114] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
