Rather, they are merely examples of methods and apparatuses consistent with some aspects of the present application as detailed in the appended claims.

[0081] The terms "first", "second", "third", "fourth" and the like in the description and in the claims of the present application, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of the terms so construed herein is merely for convenience and brevity and in no way a limitation on the scope of the application. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0082] At present, with the battery in short supply in the new energy industry, the related equipment involved in battery production also needs to improve the capacity, for example, the glue sticking equipment for battery cells usually includes glue feeding mechanism, glue pulling mechanism, glue preparing mechanism, glue cutting mechanism, etc., wherein the glue preparing mechanism can also be called glue sticking mechanism, which can perform glue sticking after preparing glue. However, these mechanisms in the related art are generally driven by separate power units, and the action sequence is more, and more complex control logic is needed to ensure that they do not interfere with each other. Because the control logic becomes complex, more uncertain factors are caused, and the reliability of the equipment is reduced.

[0083] In view of the above problems existing in the prior art, the present application provides a glue sticking equipment. The glue sticking equipment provided by the present application comprises a device body and a unwinding unit, a glue sticking unit, a glue cutting unit and a driving unit arranged on the device body. The glue pulling station and the glue sticking station are arranged on the device body to perform glue pulling and glue sticking operations. The unwinding unit is used for conveying adhesive tape, the glue sticking unit has a glue fixing part, and the glue cutting unit is in transmission connection with the glue sticking unit. The driving unit is in transmission connection with the glue sticking unit to drive the glue sticking unit to move between the glue pulling station and the glue sticking station. In the glue pulling station, the driving unit drives the glue sticking unit to move away from the battery cell, drives the glue cutting unit to move away from the glue fixing part, and drives the glue fixing part to rotate by a preset angle. In the glue sticking station, the driving unit drives the glue sticking unit to move close to the battery cell, drives the glue cutting unit to move close to the glue fixing part, cuts the adhesive tape to form a glue piece, and enables the glue fixing part close to the battery cell to stick the glue piece to the battery cell. Thus, the single driving unit drives the glue sticking unit and the glue cutting unit to move at the same time, the logic control is simpler and more reliable, the overall structure of the equipment is more compact, and the space occupied is smaller.

[0084] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described in detail in some examples.

[0085] Please refer to Figures 1-5As shown, the embodiment of the present application provides a taping device for taping the battery cell 20 with the adhesive tape 10, which comprises a device body 100, and a tape unwinding unit 200, a taping unit 300, a tape cutting unit 400 and a driving unit 500 arranged on the device body 100.

[0086] The device body 100 is provided with a tape pulling station 110 and a taping station 120, the tape unwinding unit 200 is used for conveying the adhesive tape 10, the taping unit 300 is provided with a tape fixing part 301, and the tape cutting unit 400 is drivingly connected with the taping unit 300.

[0087] The driving unit 500 is drivingly connected with the taping unit 300 to drive the taping unit 300 to move between the tape pulling station 110 and the taping station 120.

[0088] At the tape pulling station 110, the driving unit 500 drives the taping unit 300 to move away from the battery cell 20, and drives the tape cutting unit 400 to move away from the tape fixing part 301, and the driving unit 500 drives the tape fixing part 301 to rotate by a preset angle θ.

[0089] At the taping station 120, the driving unit 500 drives the taping unit 300 to move close to the battery cell 20, and drives the tape cutting unit 400 to move close to the tape fixing part 301 to cut the adhesive tape 10 into a tape piece, so that the tape fixing part 301 close to the battery cell 20 can tape the tape piece on the battery cell 20.

[0090] The adhesive tape 10 in the embodiment can be a thin strip or sheet material in a strip shape, such as an insulating adhesive tape, and the battery cell 20 can be a plate or block structure in a cuboid shape, and the taping device can be used to cut the adhesive tape 10 into a tape piece of a determined length along the width direction, and then tape the tape piece on a surface of the battery cell 20 for the next production process.

[0091] The device body 100 in the embodiment is used for supporting and providing a mounting base, which can be in a frame shape, a shell shape or the like, and can be formed by integral molding or splicing. The device body 100 is provided with the tape pulling station 110 and the taping station 120, wherein the tape pulling station 110 and the taping station 120 correspond to two working state intervals, the tape pulling station 110 is used for preparing before taping, and the taping station 120 is used for completing taping.

[0092] It should be noted that the battery cell 20 can be sequentially sent to the taping station 120 by another conveying mechanism, and the conveying mechanism is not shown in the figure, and of course another workbench can be provided, and the battery cell 20 can be placed on the workbench by hand for taping, and then the battery cell 20 can be taken down.

[0093] The unwinding unit 200 in the embodiment is used to deliver the adhesive tape 10 to the taping unit 300. The taping unit 300 can be a driving unwinding mechanism such as a motor, and the rotation speed of the motor is controlled to be consistent with the taping speed. Alternatively, the taping unit 300 can be a passive unwinding mechanism such as a rotary damper, which ensures that the adhesive tape 10 is not tangled during the delivery process.

[0094] The taping unit 300 in the embodiment is used to pull and tape the adhesive tape 10. The taping unit 300 can be a taping mechanism such as a rotating disc. The taping unit 300 has a taping part 301 arranged in a ring shape. The taping part 301 is rotatable relative to the center of the ring. The taping part 301 is used to tightly hold one side of the adhesive tape 10. The taping part 301 can be fixed by negative pressure adsorption, small adhesive force bonding, or other taping structures that do not affect the taping of the adhesive tape 10 to the battery cell 20.

[0095] The cutting unit 400 is used to cut the adhesive tape 10 on the taping unit 300 into adhesive pieces of a certain length. The length is matched with the range of the battery cell 20 that needs to be taped. The cutting unit 400 can be a cutter mechanism or a laser cutting mechanism. The cutting unit 400 is in transmission connection with the taping unit 300. The movement of the taping unit 300 drives the cutting unit 400 to cut the adhesive tape 10.

[0096] The driving unit 500 is used to drive the taping unit 300 to move between the taping position 110 and the taping position 120. The driving unit 500 can be a linear driving mechanism such as a motor-crank slider mechanism, a telescopic mechanism, a screw mechanism, or a gear and rack mechanism.

[0097] Specifically, as shown in Figure 1 , Figure 4 , at the taping position 110, the driving unit 500 drives the taping unit 300 to move away from the battery cell 20, and drives the cutting unit 400 to move away from the taping part 301. The driving unit 500 drives the taping part 301 to rotate by a preset angle θ, and completes the preparation before taping. At the taping position 120, the driving unit 500 drives the taping unit 300 to move close to the battery cell 20, and drives the cutting unit 400 to move close to the taping part 301. The adhesive tape 10 is cut into adhesive pieces. The taping part 301 close to the battery cell 20 tapes the adhesive pieces to the battery cell 20, and completes the taping. Then, the next taping cycle is continued.

[0098] It should be noted that the arc length of the preset angle θ of the taping part 301 corresponds to the length of the taped adhesive pieces. The length can be determined according to the length of the battery cell 20 that needs to be taped.

[0099] Compared with the operation of driving each mechanism on the taping device by a separate power unit, the application of the taping device in the embodiment drives the taping unit 300 and the cutting unit 400 to move simultaneously by a single driving unit 500. The logical control is simpler and more reliable. The overall structure of the device is more compact, and the occupied space is smaller.

[0100] Thus, the gluing device provided in the embodiments of the present application comprises a device body 100 and a unwinding unit 200, a gluing unit 300, a cutting unit 400 and a driving unit 500 arranged on the device body 100. The gluing and gluing operations are performed by arranging a pulling work station 110 and a gluing work station 120 on the device body 100. The unwinding unit 200 is used to convey the adhesive tape 10, the gluing unit 300 is provided with a gluing part 301, and the cutting unit 400 is drivingly connected with the gluing unit 300. The driving unit 500 is drivingly connected with the gluing unit 300 to drive the gluing unit 300 to move between the pulling work station 110 and the gluing work station 120. In the pulling work station 110, the driving unit 500 drives the gluing unit 300 to move away from the battery cell 20, and drives the cutting unit 400 to move away from the gluing part 301, and the driving unit 500 drives the gluing part 301 to rotate by a preset angle θ. In the gluing work station 120, the driving unit 500 drives the gluing unit 300 to move close to the battery cell 20, and drives the cutting unit 400 to move close to the gluing part 301, cuts the adhesive tape 10 to form a piece of adhesive tape, and makes the gluing part 301 close to the battery cell 20 to glue the piece of adhesive tape on the battery cell 20. Thus, the single driving unit 500 is used to drive the gluing unit 300 and the cutting unit 400 to move simultaneously, the logic control is simpler and more reliable, the overall structure of the device is more compact, and the device occupies less space.

[0101] In a possible design, the driving unit 500 comprises a driving mechanism 510 and an intermittent rotation mechanism 520. The driving mechanism 510 is drivingly connected with the gluing unit 300 and is used to drive the gluing unit 300 to move.

[0102] The intermittent rotation mechanism 520 is arranged on the device body 100 and is drivingly connected with the gluing unit 300. The intermittent rotation mechanism 520 is used to drive the gluing part 301 to rotate intermittently.

[0103] Specifically, as shown in Figure 3 the driving mechanism 510 is used to drive the gluing unit 300 to move, and the intermittent rotation mechanism 520 is used to drive the gluing part 301 to rotate intermittently, i.e. to rotate by a preset angle θ each time, and to rotate through an arc length corresponding to a piece of adhesive tape.

[0104] For example, in the embodiments of the present application, the intermittent rotation mechanism 520 comprises a ratchet wheel 521, a pawl 522 and a limiting assembly 523. The ratchet wheel 521 is coaxially connected with the gluing part 301.

[0105] The pawl 522 is rotationally connected on the device body 100 and abuts against the ratchet wheel 521. In the pulling work station 110, the pawl 522 is used to drive the ratchet wheel 521 to rotate, so as to drive the gluing part 301 to rotate.

[0106] The limiting assembly 523 is movably arranged on the gluing unit 300 and is used to provide a preset rotation resistance for the gluing part 301.

[0107] Specifically, as shown in Figure 2 、 Figure 3 , the ratchet wheel 521 is coaxially connected with the gluing part 301, i.e., the ratchet wheel 521 rotates synchronously with the gluing part 301, and one tooth of the ratchet wheel 521 can stick one piece of glue. The pawl 522 can be connected to the equipment body 100 through a rotating structure such as a rotating shaft, and the pawl 522 can be ensured to be in contact with the ratchet wheel 521 through a spring or the like. The limiting assembly 523 is used to provide a preset rotation resistance for the gluing part 301 to prevent the gluing part 301 from rotating freely, which can be a jacking limiting structure, a rotation damper, etc.

[0108] More specifically, as shown in Figure 3 、 Figure 4 , when the driving mechanism 510 drives the gluing unit 300 to rise, as in the processes a, b, and c in Figure 4 , the ratchet wheel 521 moves upward and starts to keep from rotating, and when continuously rising, the pawl 522 pushes the ratchet wheel 521 to rotate counterclockwise by one tooth pitch after overcoming the preset rotation resistance. When the driving mechanism 510 drives the gluing unit 300 to descend, as in the processes c, d, and e in Figure 4 , the ratchet wheel 521 moves downward, and the limiting assembly 523 keeps the ratchet wheel 521 from rotating all the time.

[0109] It should be noted that the number of teeth on the ratchet wheel 521 is consistent with the number of pieces of glue to be stuck, which can be determined according to actual needs, and is not specifically limited in the embodiment.

[0110] Further, in the embodiment, the limiting assembly 523 includes a limiting piece 5231 and an elastic piece 5232, and the limiting piece 5231 is connected to the gluing unit 300 through the elastic piece 5232.

[0111] The gluing unit 300 has a rotating part 302 coaxially rotating with the gluing part 301, and the limiting piece 5231 abuts against the rotating part 302.

[0112] Specifically, as shown in Figure 3 , the limiting piece 5231 can be a limiting rod, which can be movably arranged on the gluing unit 300, and the elastic piece 5232 can be a spring. The limiting piece 5231 is connected to the gluing unit 300 through the elastic piece 5232, and the gluing unit 300 has a rotating part 302 coaxially rotating with the gluing part 301, such as a rotary disc, etc. The limiting piece 5231 abuts against the rotating part 302.

[0113] That is, the limiting member 5231 and the elastic member 5232 move together with the adhesive unit 300, but the limiting member 5231 elastically abuts against the rotating part 302 to limit the free rotation of the rotating part 302 and the adhesive part 301. Among them, the elastic member 5232 is related to the preset rotation resistance, which can be determined according to actual needs. In addition, a guide rod or the like can also be arranged between the limiting member 5231 and the adhesive unit 300 to ensure that the limiting member 5231 moves stably, and this embodiment is not limited specifically.

[0114] Further, in the embodiment, a first limiting part 5201 is arranged on one side of the limiting member 5231 facing the rotating part 302, and a plurality of second limiting parts 303 are arranged on the rotating part 302 in intervals.

[0115] The included angle between the adjacent two second limiting parts 303 and the rotation center of the rotating part 302 is a preset angle θ, and the first limiting part 5201 abuts against each second limiting part 303 to limit the adhesive part 301 at the current position.

[0116] In one example, as shown in Figure 3 the first limiting part 5201 is a protrusion, and the second limiting part 303 is a groove, and when the protrusion is inserted into one of the grooves, the adhesive part 301 can be limited at the current position.

[0117] In another example, not shown in the figure, the first limiting part 5201 can also be a groove, and the second limiting part 303 is a protrusion, and when one of the protrusions is inserted into the groove, the adhesive part 301 can also be limited at the current position.

[0118] It should be noted that the groove is a relatively shallow V-shaped groove to ensure that the protrusion can slide out of the groove after overcoming the preset rotation resistance, so as to avoid the situation of being stuck, which can be determined according to actual needs, and this embodiment is not limited too much.

[0119] Further, in the embodiment, the driving mechanism 510 includes a first driving assembly 511 and a transmission assembly 512, and the first driving assembly 511 is connected with the adhesive unit 300 through the transmission assembly 512.

[0120] Specifically, the first driving assembly 511 can be a motor, and the transmission assembly 512 can be a crank slider assembly, so that the motor drives the reciprocating movement of the adhesive unit 300 through the crank slider assembly.

[0121] Of course, the driving mechanism 510 can also be replaced by other types of driving components, and components capable of driving linear reciprocating movement can be used, and this embodiment is not limited too much.

[0122] In some embodiments, the adhesive applying unit 300 comprises a first mounting base 310 and a rotating disc 320, the first mounting base 310 is arranged on the device body 100 and moves between the adhesive pulling station 110 and the adhesive applying station 120.

[0123] The rotating disc 320 is rotationally connected to the first mounting base 310, and the adhesive fixing part 301 is located at the circumferential side of the rotating disc 320.

[0124] Specifically, as shown in Figure 2 , the first mounting base 310 can be block-shaped, plate-shaped or the like, which can be connected to the device body 100 through a guide rail, a sliding structure, and the like. The driving unit 500 is drivingly connected to the first mounting base 310, and can drive the first mounting base 310 to move between the adhesive pulling station 110 and the adhesive applying station 120. The rotating disc 320 is rotationally connected to the first mounting base 310 through a rotating shaft or the like, and the rotating direction thereof is perpendicular to the moving direction of the first mounting base 310. The adhesive fixing part 301 is arranged on the circumference of the rotating disc 320.

[0125] In this way, when the first mounting base 310 is at the adhesive pulling station 110, the rotating disc 320 moves away from the battery cell 20 first and then rotates by a preset angle θ to realize the adhesive pulling. When the first mounting base 310 is at the adhesive applying station 120, the rotating disc 320 moves close to the battery cell 20 to realize the adhesive applying.

[0126] Further, in the present embodiment, the adhesive fixing part 301 is composed of a plurality of adhesive fixing segments 3011 arranged at intervals, and a cutting groove 3012 is arranged between two adjacent adhesive fixing segments 3011. The cutting groove 3012 is used for the cutting knife 400 to cut the adhesive tape 10.

[0127] Specifically, the plurality of adhesive fixing segments 3011 are arranged at intervals around the circumference of the rotating disc 320, and the cutting groove 3012 between two adjacent adhesive fixing segments 3011 is opened along the radial direction of the rotating disc 320, facilitating the cutting knife to cut the adhesive tape. Each adhesive fixing segment 3011 corresponds to the length of one piece of adhesive, and the number of adhesive fixing segments 3011 is the same as the number of teeth of the ratchet wheel 521.

[0128] Further, in the present embodiment, the adhesive applying unit 300 further comprises a negative pressure piece 330, and a plurality of negative pressure parts 3013 are opened on the adhesive fixing segment 3011, and the negative pressure parts 3013 are in communication with the negative pressure piece 330.

[0129] Specifically, in combination with Figure 2 , Figure 5As shown, the negative pressure device 330 can be a negative pressure pump or a negative pressure suction system, and a plurality of negative pressure portions 3013, i.e. negative pressure suction holes, can be arranged on each adhesive segment 3011 in an interval manner. The negative pressure portions 3013 can be communicated with the negative pressure device 330 through pipelines or flow channels, so as to suck the adhesive tape on the adhesive segment 3011. For example, two rows of negative pressure portions 3013 are arranged on each adhesive segment 3011 in a radial direction, and a clearance is left between the two rows of negative pressure portions 3013.

[0130] Further, the adhesive taping unit 300 further comprises an air slide ring 340 and a control valve 350. The rotating disc 320 has a plurality of channels 321, and each channel 321 is communicated with the negative pressure portion 3013 on each adhesive segment 3011.

[0131] Each channel 321 is connected with the negative pressure device 330 through the air slide ring 340 and the control valve 350. The control valve 350 is configured to control the corresponding channel 321 to be communicated with the outside when the current adhesive segment 3011 tapes the adhesive film on the battery cell 20.

[0132] Specifically, a plurality of channels 321 are arranged in the rotating disc 320 and the rotating shaft thereof, and the number of the channels 321 is the same as the number of the adhesive segments 3011. The air slide ring 340 is connected to the rotating shaft on one side of the rotating disc 320. Each channel 321 is connected with the negative pressure device 330 through the air slide ring 340 and the control valve 350. The air slide ring 340 can ensure continuous suction when the rotating disc 320 rotates. The control valve 350 can selectively control the opening and closing of each channel 321, and can control each channel 321 to be communicated with the outside air to break the vacuum.

[0133] In this way, when the current adhesive segment 3011 tapes the adhesive film on the battery cell 20, the control valve 350 controls the corresponding channel 321 of the adhesive segment 3011 to be communicated with the outside, so as to release the negative pressure on the adhesive film, thereby avoiding the adhesive film taped on the battery cell 20 to be sucked up again.

[0134] The specific models of the air slide ring 340, the control valve 350 and the negative pressure device 330 can be determined according to actual needs, which are not limited in the embodiment.

[0135] In some embodiments, the adhesive cutting unit 400 comprises a cutter assembly 410, a second mounting seat 420 and a transmission mechanism 430, and the cutter assembly 410 is connected to the second mounting seat 420.

[0136] The second mounting seat 420 is movably arranged on the first mounting seat 310 and is connected with the equipment body 100 through the transmission mechanism 430.

[0137] Specifically, as shown in FIG. 4, the second mounting seat 420 is movably arranged on the first mounting seat 310, and the cutter assembly 410 is connected to the second mounting seat 420 through the transmission mechanism 430. Figure 1As shown, the cutter assembly 410 can be in a sheet, plate or other structure, which is connected to the second mounting seat 420, and the cutting edge is arranged along the radial direction of the rotating disc 320 and faces one side of the rotating disc 320.

The transmission mechanism 430 is used to ensure that the second mounting seat 420 and the cutter assembly 410 move in the direction of approaching or moving away from the rotating disc 320 while moving with the first mounting seat 310, and the transmission mechanism 430 is connected to the second mounting seat 420 and the device body 100.

[0138] Exemplarily, in the embodiment, the transmission mechanism 430 includes a first transmission member 431 and a second transmission member 432 which is in sliding connection with the first transmission member 431, and the first transmission member 431 is connected to the device body 100.

[0139] The second transmission member 432 is connected to the second mounting seat 420 and moves with the first mounting seat 310 to drive the second transmission member 432 and the second mounting seat 420 to slide relative to the first transmission member 431, so as to make the cutter assembly 410 approach or move away from the glue fixing part 301.

[0140] Specifically, as shown, Figure 3 the first transmission member 431 is a fixed block or a fixed block which is fixedly connected to the device body 100, and the second transmission member 432 is a connecting block or a connecting column which is connected to the second mounting seat 420, and the first transmission member 431 is in sliding connection with the second transmission member 432, so as to limit the moving direction of the second transmission member 432 through the first transmission member 431.

[0141] In one example, a sliding groove is formed on the first transmission member 431, and the second transmission member 432 has a protrusion matched with the sliding groove, and the protrusion is in sliding connection with the sliding groove. In another example, the first transmission member 431 is provided with a protrusion, and the second transmission member 432 has a sliding groove matched with the protrusion, and the protrusion is in sliding connection with the sliding groove.

[0142] In this way, as shown, Figure 3 when the first mounting seat 310 moves upward, the second mounting seat 420 and the cutter assembly 410 are driven to move upward, and under the limitation of the first transmission member 431, the second transmission member 432 also drives the second mounting seat 420 and the cutter assembly 410 to move away from the radial direction of the rotating disc 320, so as to realize the retreat of the cutter assembly 410 and avoid the interference of the cutter assembly 410 with the rotation of the rotating disc 320.

[0143] Similarly, when the first mounting base 310 moves downward, the second mounting base 420 and the cutter assembly 410 are driven to move downward, and under the restriction of the first transmission member 431, the second transmission member 432 also drives the second mounting base 420 and the cutter assembly 410 to move radially towards the rotating disc 320, so as to cut the adhesive tape 10.

[0145] The second driving assembly 220 is in transmission connection with the winding clamp 210 and is configured to drive the winding clamp 210 to rotate, so as to deliver the adhesive tape 10 on the winding roll 30 to the taping unit 300 through the material guiding members 230.

[0146] Specifically, as shown in Figure 1 、 Figure 2 the winding clamp 210 is rotationally connected to the device body 100 and can clamp the winding roll 30 in a disc shape, the second driving assembly 220 can be an unwinding motor or a rotation damper, which is in transmission connection with the winding clamp 210 to control the rotating speed of the winding clamp 210 and meet the unwinding requirement, and the material guiding members 230 can be material guiding rollers for guiding the adhesive tape 10, and the positions and the number of the material guiding members 230 can be arranged according to actual requirements, which are not specifically limited in the present embodiment.

[0147] In addition, a tensioning mechanism can be further arranged between the winding clamp 210 and the taping unit 300, which can comprise a swing arm, a tensioning wheel and a tension spring, the swing arm is rotationally connected to the device body 100, the tensioning wheel is rotationally connected to the swing arm, and the tension spring connects the swing arm and the device body 100.

[0148] In this way, the adhesive tape 10 winds around the tensioning wheel and is pulled tight by the tension spring through the swing arm, so that the adhesive tape 10 is in a tensioned state and avoids being in disorder. The specific structure, position, etc. of the tensioning mechanism can be determined according to actual requirements, which are not excessively limited in the present embodiment.
