[0082] At present, as the battery supply in the new energy industry exceeds the demand, the related equipment involved in battery production also urgently needs to increase production capacity. For example, the glue sticking equipment used for battery cells usually includes a glue feeding mechanism, a glue pulling mechanism, a glue preparation mechanism, a glue cutting mechanism, etc. Among them, the glue preparation mechanism can also be called a glue sticking mechanism, which can be glued after the glue is prepared. However, these mechanisms in the related technology are generally driven by a separate power unit, with multiple action sequences, and require more complex control logic to ensure non-interference. As the control logic becomes complicated, there are more uncertain factors, which reduces the reliability of the equipment.

[0083] In view of the above problems existing in the prior art, the present application provides a glue sticking device. The glue sticking device provided by the present application includes a device body and an unwinding unit, a glue sticking unit, a glue cutting unit and a driving unit arranged on the device body. By setting a glue pulling station and a glue sticking station on the device body, glue pulling and glue sticking operations can be performed. Among them, the unwinding unit is used to convey the tape, the glue sticking unit has a solid glue part, and the glue cutting unit is connected to the glue sticking unit by transmission. The driving unit is connected to the glue sticking unit by transmission to drive the glue sticking unit to move between the glue pulling station and the glue sticking station. At the glue pulling station, the driving unit drives the glue sticking unit away from the battery cell, and drives the glue cutting unit away from the solid glue part, and the driving unit drives the solid glue part to rotate a preset angle. At the glue sticking station, the driving unit drives the glue sticking unit to approach the battery cell, and drives the glue cutting unit to approach the solid glue part, cuts the tape to form a film, so that the solid glue part close to the battery cell sticks the film to the battery cell. Therefore, the glue sticking unit and the glue cutting unit are driven simultaneously by a single driving unit, making the logic control simpler and more reliable, and making the overall structure of the equipment more compact and occupying less space.

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

[0085] Please refer to Figure 1-Figure 5As shown, an embodiment of the present application provides a gluing device for applying a tape 10 to a battery cell 20 , and the gluing device includes a device body 100 , and an unwinding unit 200 , a gluing unit 300 , a gluing cutting unit 400 and a driving unit 500 arranged on the device body 100 .

[0086] The device body 100 is provided with a glue drawing station 110 and a glue sticking station 120 , the unwinding unit 200 is used to convey the adhesive tape 10 , the glue sticking unit 300 is provided with a glue fixing part 301 , and the glue cutting unit 400 is transmission-connected with the glue sticking unit 300 .

[0087] The driving unit 500 is transmission-connected to the gluing unit 300 to drive the gluing unit 300 to move between the gluing station 110 and the gluing station 120 .

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

[0089] At the glue sticking station 120 , the driving unit 500 drives the glue sticking unit 300 to approach the battery cell 20 , and drives the glue cutting unit 400 to approach the glue fixing portion 301 , cutting the tape 10 to form a glue sheet, so that the glue fixing portion 301 close to the battery cell 20 can stick the glue sheet to the battery cell 20 .

[0090] The tape 10 in this embodiment can be a thin strip or sheet material in a band shape, such as an insulating tape, and the battery cell 20 can be a rectangular plate or block structure. The glue sticking equipment can be used to cut the tape 10 into films of a certain length along the width direction, and then stick the film to a surface of the battery cell 20 for the next production process.

[0091] The device body 100 in this embodiment is used for support and provides an installation foundation. It can be a frame-shaped, shell-shaped structure, etc., and can be formed by integral molding or splicing. The device body 100 has a glue pulling station 110 and a glue sticking station 120, wherein the glue pulling station 110 and the glue sticking station 120 are equivalent to two working state intervals. The glue pulling station 110 is used for preparation before glue sticking, and the glue sticking station 120 is used for completion of glue sticking.

[0092] It should be noted that the battery cells 20 can be sequentially delivered to the gluing station 120 through another conveying mechanism, which is not shown in the figure. Of course, another workbench can also be set up, and the battery cells 20 can be manually placed on the workbench for gluing, and then the battery cells 20 can be removed.

[0093] The unwinding unit 200 in this embodiment is used to convey the adhesive tape 10 to the gluing unit 300. It can be an active unwinding mechanism, such as a motor, which controls the motor speed to keep consistent with the gluing speed, or it can be a passive unwinding mechanism, such as a rotary damper, to ensure that the adhesive tape 10 will not be disordered during the conveying process.

[0094] The glue sticking unit 300 in this embodiment is used for glue pulling and glue sticking, and it can be a glue sticking mechanism such as a turntable. The glue sticking unit 300 has a glue fixing portion 301, which is arranged in a ring shape and can rotate relative to the center of the ring. The glue fixing portion 301 is used to suck one side of the tape 10 tightly, and it can be fixed by negative pressure adsorption, small bonding force, etc., without affecting the glue fixing structure that sticks the tape 10 to the battery cell 20.

[0095] The glue cutting unit 400 is used to cut the entire tape 10 on the glue sticking unit 300 into pieces of tape of a certain length, which matches the range of glue sticking required on the battery cell 20. It can be a cutting mechanism or a laser cutting mechanism, etc. The glue cutting unit 400 is connected to the glue sticking unit 300 by transmission, so that the glue cutting unit 400 can be driven to cut glue by the movement of the glue sticking unit 300.

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

[0097] Specifically, combined Figure 1 , Figure 4 As shown, at the glue pulling station 110, the driving unit 500 drives the glue sticking unit 300 away from the battery cell 20, and drives the glue cutting unit 400 away from the glue fixing part 301, and the driving unit 500 drives the glue fixing part 301 to rotate by a preset angle θ, completing the preparation before glue sticking. At the glue sticking station 120, the driving unit 500 drives the glue sticking unit 300 close to the battery cell 20, and drives the glue cutting unit 400 close to the glue fixing part 301, cuts the tape 10 to form a film, so that the glue fixing part 301 close to the battery cell 20 sticks the film to the battery cell 20, completes the glue sticking, and then continues the next glue sticking cycle.

[0098] It should be noted that the arc length of the preset angle θ corresponding to the adhesive portion 301 is the length of the adhesive sheet to be pasted, which can be determined according to the length of the adhesive sheet to be pasted on the battery cell 20 .

[0099] Compared with a separate power unit driving the operation of each mechanism on the glue laminating device, the application of the glue laminating device in the embodiment of the present application uses a single drive unit 500 to simultaneously drive the glue laminating unit 300 and the glue cutting unit 400, making the logic control simpler and more reliable, and making the overall structure of the device more compact and occupying less space.

[0100] Thus, the glue sticking device provided in the embodiment of the present application includes a device body 100 and an unwinding unit 200, a glue sticking unit 300, a glue cutting unit 400 and a driving unit 500 arranged on the device body 100. By setting a glue pulling station 110 and a glue sticking station 120 on the device body 100, glue pulling and glue sticking operations can be performed. Among them, the unwinding unit 200 is used to convey the tape 10, the glue sticking unit 300 has a solid glue portion 301, and the glue cutting unit 400 is connected to the glue sticking unit 300 by transmission. By connecting the driving unit 500 to the glue sticking unit 300 by transmission, the glue sticking unit 300 is driven to move between the glue pulling station 110 and the glue sticking station 120. At the glue pulling station 110, the driving unit 500 drives the glue sticking unit 300 away from the battery cell 20, and drives the glue cutting unit 400 away from the solid glue portion 301, and the driving unit 500 drives the solid glue portion 301 to rotate a preset angle θ. At the glue sticking station 120, the driving unit 500 drives the glue sticking unit 300 to approach the battery cell 20, and drives the glue cutting unit 400 to approach the glue fixing part 301, cuts the tape 10 to form a glue sheet, so that the glue fixing part 301 close to the battery cell 20 sticks the glue sheet to the battery cell 20. Thus, the glue sticking unit 300 and the glue cutting unit 400 are driven to operate simultaneously by a single driving unit 500, making the logic control simpler and more reliable, making the overall structure of the device more compact and occupying less space.

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

[0102] The intermittent rotating mechanism 520 is disposed on the equipment body 100 and is in driving connection with the glue sticking unit 300. The intermittent rotating mechanism 520 is used to drive the glue fixing part 301 to rotate intermittently.

[0103] Specifically, Figure 3 As shown, the driving mechanism 510 is used to drive the glue laminating unit 300 to move, and the intermittent rotating mechanism 520 is used to drive the glue fixing part 301 to rotate intermittently, that is, each time it rotates by a preset angle θ, it also rotates by an arc length corresponding to a piece of film.

[0104] Illustratively, in this embodiment, the intermittent rotating mechanism 520 includes a ratchet 521 , a pawl 522 and a limiting assembly 523 , and the ratchet 521 is coaxially connected to the adhesive fixing portion 301 .

[0105] The ratchet 522 is rotatably connected to the device body 100 and abuts against the ratchet 521 . At the glue pulling station 110 , the ratchet 522 is used to push the ratchet 521 to rotate, thereby driving the glue fixing part 301 to rotate.

[0106] The limiting assembly 523 is movably disposed on the glue applying unit 300 and is used to provide a preset rotation resistance to the glue fixing portion 301 .

[0107] Specifically, Figure 2 , Figure 3 As shown, the ratchet 521 is coaxially connected to the adhesive part 301, that is, the ratchet 521 rotates synchronously with the adhesive part 301, and one film can be attached every time the ratchet 521 rotates one tooth. The pawl 522 can be connected to the device body 100 through a rotating structure such as a rotating shaft, and the pawl 522 can be ensured to contact with the ratchet 521 through components such as a spring. The limiting component 523 is used to provide a preset rotation resistance to the adhesive part 301 to prevent the adhesive part 301 from rotating freely. It can be a top-tightening limiting structure, a rotation damper, etc.

[0108] More specifically, if Figure 3 , Figure 4 As shown, when the driving mechanism 510 drives the glue sticking unit 300 to rise, as shown in FIG. Figure 4 In the processes a, b, and c in the figure, the ratchet wheel 521 moves upward and initially remains stationary. When the ratchet wheel 521 continues to rise and overcomes the preset rotation resistance, the ratchet pawl 522 pushes the ratchet wheel 521 to rotate counterclockwise by one tooth pitch. Figure 4 In the processes c, d, and e, the ratchet wheel 521 moves downward, and the limiting assembly 523 keeps the ratchet wheel 521 from rotating.

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

[0110] Furthermore, in this embodiment, the limiting assembly 523 includes a limiting member 5231 and an elastic member 5232 , and the limiting member 5231 is connected to the glue laminating unit 300 via the elastic member 5232 .

[0111] The glue laminating unit 300 has a rotating portion 302 that rotates coaxially with the glue fixing portion 301 , and the stopper 5231 abuts against the rotating portion 302 .

[0112] Specifically, Figure 3 As shown, the limit member 5231 can be a limit rod, which can be movably set on the upper glue unit 300, and the elastic member 5232 can be a spring. The limit member 5231 is connected to the glue unit 300 through the elastic member 5232. The glue unit 300 has a rotating part 302 that rotates coaxially with the solid glue part 301, such as a turntable, and the limit member 5231 abuts against the rotating part 302.

[0113] That is, the limiting member 5231 and the elastic member 5232 move together with the glue sticking unit 300, but the limiting member 5231 elastically contacts the rotating part 302 to limit the free rotation of the rotating part 302 and the glue fixing 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 be provided between the limiting member 5231 and the glue sticking unit 300 to ensure the stable movement of the limiting member 5231, which is not specifically limited in this embodiment.

[0114] Furthermore, in this embodiment, a first limiting portion 5201 is provided on the limiting member 5231 on a side facing the rotating portion 302 , and a plurality of second limiting portions 303 are provided at intervals on the rotating portion 302 .

[0115] The angle formed by the line connecting two adjacent second limiting portions 303 and the rotation center of the rotating portion 302 is a preset angle θ, and the first limiting portion 5201 abuts against each second limiting portion 303 to limit the adhesive fixing portion 301 at the current position.

[0116] In one example, Figure 3 As shown, the first limiting portion 5201 is a protrusion, and the second limiting portion 303 is a groove. When the protrusion is inserted into one of the grooves, the adhesive fixing portion 301 can be limited to the current position.

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

[0118] It should be noted that the groove is a shallow V-shaped groove to ensure that after overcoming the preset rotational resistance, the protrusion can slide out of the groove to avoid getting stuck. It can be determined according to actual needs and is not excessively restricted in this embodiment.

[0119] Furthermore, in this embodiment, the driving mechanism 510 includes a first driving component 511 and a transmission component 512 , and the first driving component 511 is connected to the glue laminating unit 300 via the transmission component 512 .

[0120] Specifically, the first driving component 511 may be a motor, and the transmission component 512 may be a crank slider component, so that the motor drives the reciprocating movement of the glue laminating unit 300 through the crank slider component.

[0121] Of course, the driving mechanism 510 may also be replaced by other types of driving components, as long as the components can drive linear reciprocating motion, and no excessive restrictions are imposed in this embodiment.

[0122] In some embodiments, the glue laminating unit 300 includes a first mounting seat 310 and a turntable 320 . The first mounting seat 310 is disposed on the device body 100 and moves between the glue pulling station 110 and the glue laminating station 120 .

[0123] The rotating disk 320 is rotatably connected to the first mounting base 310 , and the adhesive fixing portion 301 is located on the peripheral side of the rotating disk 320 .

[0124] Specifically, Figure 2 As shown, the first mounting seat 310 can be a block-shaped, plate-shaped or other structure, which can be connected to the device body 100 through a guide rail or a sliding structure, and the driving unit 500 is in transmission connection with the first mounting seat 310, and can drive the first mounting seat 310 to move between the glue pulling station 110 and the glue sticking station 120. The turntable 320 can be rotatably connected to the first mounting seat 310 through a rotating shaft or other components, and its rotation direction is perpendicular to the movement direction of the first mounting seat 310, and the glue fixing part 301 is arranged on the circumference of the turntable 320.

[0125] Thus, when the first mounting seat 310 is at the glue pulling station 110, the turntable 320 first moves away from the battery cell 20 and then rotates by a preset angle θ to achieve glue pulling. When the first mounting seat 310 is at the glue sticking station 120, the turntable 320 moves close to the battery cell 20 to achieve glue sticking.

[0126] Furthermore, in this embodiment, the adhesive fixing portion 301 is composed of a plurality of adhesive fixing segments 3011 disposed at intervals, and a cutting groove 3012 is disposed between two adjacent adhesive fixing segments 3011 . The cutting groove 3012 is used for the adhesive cutting unit 400 to cut the adhesive tape 10 .

[0127] Specifically, a plurality of adhesive segments 3011 are arranged at intervals around the circumference of the rotating disk 320, and the cutting groove 3012 between two adjacent adhesive segments 3011 is opened along the radial direction of the rotating disk 320, so as to facilitate the cutter to cut the tape. Each adhesive segment 3011 corresponds to the length of a film, and the number of adhesive segments 3011 is the same as the number of teeth of the ratchet 521.

[0128] Furthermore, in this embodiment, the glue sticking unit 300 further includes a negative pressure member 330 , and a plurality of negative pressure portions 3013 are provided on the glue fixing section 3011 , and the negative pressure portions 3013 are in communication with the negative pressure member 330 .

[0129] Specifically, combined Figure 2 , Figure 5As shown, the negative pressure member 330 may be a negative pressure pump or a negative pressure suction system, and a plurality of negative pressure parts 3013, i.e., negative pressure suction holes, may be arranged at intervals on each adhesive solid segment 3011, and the negative pressure parts 3013 may be connected to the negative pressure member 330 through a pipeline or a flow channel, so as to suck the adhesive tape tightly onto the adhesive solid segment 3011. For example, two rows of negative pressure parts 3013 are arranged radially on each adhesive solid segment 3011, and an escape groove is left between the two rows of negative pressure parts 3013.

[0130] Furthermore, the glue sticking unit 300 further includes an air slip ring 340 and a control valve 350 . The rotating disk 320 has a plurality of channels 321 , and each channel 321 is correspondingly connected to a negative pressure portion 3013 on each glue solidifying section 3011 .

[0131] Each channel 321 is connected to the negative pressure member 330 via an air slip ring 340 and a control valve 350 . The control valve 350 is configured to control the corresponding channel 321 to communicate with the outside when the current adhesive solidifying section 3011 attaches the adhesive to the battery cell 20 .

[0132] Specifically, a plurality of channels 321 are provided in the rotating disk 320 and in the rotating shaft, and the number of the channels 321 is the same as the number of the solid glue sections 3011. The air slip ring 340 is connected to the rotating shaft on one side of the rotating disk 320, and each channel 321 is connected to the negative pressure member 330 through the air slip ring 340 and the control valve 350. The air slip ring 340 can ensure continuous air extraction when the rotating disk 320 rotates, and the control valve 350 can selectively control the on-off of each channel 321, and can control each channel 321 to communicate with the outside atmosphere to break the vacuum.

[0133] In this way, when the current solid glue segment 3011 sticks the film to the battery cell 20, the control valve 350 controls the channel 321 corresponding to the solid glue segment 3011 to connect with the outside world, releases the negative pressure on the film, and thus avoids the film stuck on the battery cell 20 being sucked up again.

[0134] The specific models of the gas slip ring 340 , the control valve 350 and the negative pressure member 330 can be determined according to actual needs and are not specifically limited in this embodiment.

[0135] In some embodiments, the rubber cutting unit 400 includes 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 disposed on the first mounting seat 310 and is connected to the device body 100 via a transmission mechanism 430 .

[0137] Specifically, Figure 1As shown, the cutter assembly 410 can be a sheet-like, plate-like structure, etc., which is connected to the second mounting seat 420, and the blade is arranged along the radial direction of the rotating disk 320 and faces one side of the rotating disk 320. The second mounting seat 420 can be a block-like, plate-like structure, etc., which can be set on the first mounting seat 310 through a guide rail and a sliding structure, that is, it moves with the first mounting seat 310. The transmission mechanism 430 is used to ensure that the second mounting seat 420 and the cutter assembly 410 move with the first mounting seat 310, and move in a direction close to or away from the rotating disk 320. The transmission mechanism 430 connects the second mounting seat 420 and the device body 100.

[0138] Illustratively, in this embodiment, the transmission mechanism 430 includes a first transmission member 431 and a second transmission member 432 slidably connected to 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 the first mounting seat 310 moves to drive the second transmission member 432 and the second mounting seat 420 to slide relative to the first transmission member 431 , so that the cutter assembly 410 is close to or away from the adhesive fixing portion 301 .

[0140] Specifically, Figure 3 As shown, the first transmission member 431 is a fixed block or a fixed block, which is fixedly connected to the equipment 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 slidably connected to the second transmission member 432, so that the moving direction of the second transmission member 432 is limited by the first transmission member 431.

[0141] In one example, a slide groove is provided on the first transmission member 431, and a protrusion matching the slide groove is provided on the second transmission member 432, and the protrusion is slidably connected to the slide groove. In another example, a protrusion is provided on the first transmission member 431, and a slide groove matching the protrusion is provided on the second transmission member 432, and the protrusion is slidably connected to the slide groove.

[0142] In this way, if Figure 3 As shown, when the first mounting seat 310 moves upward, it drives the second mounting seat 420 and the cutter assembly 410 to move upward. At the same time, under the limiting action 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 radially away from the turntable 320, thereby retracting the cutter and preventing the cutter assembly 410 from interfering with the rotation of the turntable 320.

[0143] Similarly, when the first mounting seat 310 moves downward, it drives the second mounting seat 420 and the cutter assembly 410 to move downward. At the same time, under the limiting action 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 radially toward the turntable 320 to cut the tape 10.

[0144] In some embodiments, the unwinding unit 200 includes a winding clamp 210 , a second driving assembly 220 and a plurality of material guides 230 . The winding clamp 210 and the plurality of material guides 230 are rotatably connected to the device body 100 . The winding clamp 210 is used to clamp the film 30 .

[0145] The second driving assembly 220 is in driving connection with the winding clamp 210 and is configured to drive the winding clamp 210 to rotate so as to transport the adhesive tape 10 on the film roll 30 to the adhesive laminating unit 300 through the material guides 230 .

[0146] Specifically, Figure 1 , Figure 2 As shown, the winding clamp 210 is rotatably connected to the device body 100, on which the disc-shaped film 30 can be clamped. The second driving component 220 can be an unwinding motor or a rotation damper, which is connected to the winding clamp 210 in a transmission manner to control the rotation speed of the winding clamp 210 to meet the unwinding requirements. The guide member 230 can be a guide roller for guiding the tape 10. The position and number of the guide members 230 can be arranged according to actual needs, and are not specifically limited in this embodiment.

[0147] In addition, a tensioning mechanism can be set between the winding clamp 210 and the glue laminating unit 300, which can include a swing arm, a tensioning wheel and a tension spring. The swing arm is rotatably connected to the device body 100, the tensioning wheel is rotatably 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 passes around the tension wheel and the swing arm is tightened by the tension spring, so that the adhesive tape 10 is in a tensioned state to avoid disorder of the adhesive tape 10. Among them, the specific structure and position of the tensioning mechanism can be determined according to actual needs, and no excessive restrictions are made in this embodiment.
