[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0053] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0054] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0056] When manufacturing batteries, in order to prevent short circuits or contamination of the battery cells, a layer of protective glue or tape is applied to the side of the battery cells. This not only keeps the battery cells clean but also increases the mechanical strength of the battery cells, reducing damage to the battery cells caused by vibration, collision, etc. during transportation or use.

[0057] In the related art, some glue laminating equipment includes a glue preparation device and a glue laminating device. After the tape is unwound, the glue preparation device cuts the tape into films. The process of cutting the films involves setting the glue, pulling the glue and cutting the glue. The process is complicated and time-consuming, which affects the glue laminating efficiency of the glue laminating device and leads to low overall efficiency of the glue laminating device. In addition, when the tape is exhausted, the glue laminating device needs to be shut down to replace the tape in the unwinding reel, which not only affects the working efficiency of the glue laminating device, but also affects the production efficiency of subsequent processes.

[0058] Based on the above, the embodiment of the present application provides a gluing device that can complete tape replacement without stopping the machine, and the gluing device in the gluing device is configured with at least two glue preparation devices, thereby improving the overall working efficiency of the gluing device.

[0059] Figure 1 and Figure 2 A glue sticking device 100 provided in an embodiment of the present application is shown, and the glue sticking device 100 includes at least two glue preparation devices 1 and a glue sticking device 2. The at least two glue preparation devices 1 can work independently and are arranged along a first direction. Each glue preparation device 1 includes a glue sticking station A that can accommodate battery cells; at least part of the glue sticking device 2 can move between at least two glue sticking stations A along the first direction, and each glue preparation device 1 is used to provide a film C2 to the glue sticking device 2, and the glue sticking device 2 sticks the film C2 to the battery cell in the corresponding glue sticking station A.

[0060] The glue sticking device 100 may have a length direction, a width direction and a height direction, wherein the first direction may be the length direction or the width direction of the glue sticking device 100. Specifically, the glue sticking device 100 is used to glue the battery cells transported to the glue sticking station A by the conveyor belt, wherein the extending direction of the conveyor belt is the first direction. Figure 1 The X direction shown in FIG. 1 and the height direction of the adhesive laminating device 100 are Figure 1 and Figure 2 The Z direction is shown in FIG.

[0061] The glue preparation device 1 is used to cut the coiled adhesive tape C1 into films C2 of a preset length. In order to facilitate gluing of the battery cells transported along the first direction, at least two glue preparation devices 1 are arranged at intervals along the first direction. Each glue preparation device 1 includes a gluing station A, that is, the gluing device 100 includes at least two gluing stations A arranged along the first direction, and the gluing device 2 completes the gluing operation of the battery cells at the gluing stations A. For the sake of description, the embodiment of the present application is described by taking the glue device 100 including two glue preparation devices 1 as an example.

[0062] like Figure 1 As shown, the two glue preparation devices 1 extend along the first direction, so the two glue sticking stations A also extend along the first direction. At least part of the glue sticking device 2 (such as the glue sticking assembly 21 used for glue sticking) can reciprocate along the first direction, thereby switching positions between the two glue sticking stations A to stick the glue sheets C2 cut from the two glue preparation devices 1 to the side walls of the battery cell.

[0063] It should be noted that the glue preparation device 1 needs to go through the process of setting glue, pulling glue and cutting glue to cut the adhesive tape C1 into films C2 of preset length, which is a complex process and takes a long time, while the gluing action of the gluing device 2 is relatively simple and time-saving. Therefore, two glue preparation devices 1 are configured for each gluing device 2, and the two glue preparation devices 1 can alternately provide the cut films C2 to the gluing device 2. At least part of the gluing device 2 (such as the gluing component 21 used for gluing) can greatly improve the working rhythm of the gluing device 2 by quickly switching positions at two gluing stations A along the first direction and completing gluing, thereby improving the gluing efficiency of the gluing device 100.

[0064] It is worth noting that each glue preparation device 1 in the glue laminating device 100 can work independently, that is, the two glue preparation devices 1 can be started and stopped separately, the two glue preparation devices 1 can work at the same time, and one of the glue preparation devices 1 can be stopped by the control device of the glue laminating device 100. At the same time, the glue laminating device 2 works independently of each glue preparation device 1, that is, the glue laminating device 2 can be stopped regardless of the shutdown of the glue preparation device 1, so that the glue laminating device 100 can perform a tape change operation without stopping.

[0065] For example, when the adhesive tape C1 in the two glue preparation devices 1 is about to run out, the group of glue preparation devices 1 can be controlled to stop so as to perform a tape change (replace a new tape roll) operation on the group of glue preparation devices 1. At the same time, the other glue preparation device 1 is working normally, and the glue application device 2 no longer needs to switch positions along the first direction, and stays at the glue application station A of the working glue preparation device 1, and pastes the film C2 cut by the normally working glue preparation device 1 to the side wall of the battery cell at the glue application station A, so that the glue application device 100 can realize the tape change operation without stopping. When the tape change operation is completed, the two glue preparation devices 1 work at the same time, and the glue application device 100 resumes the efficient glue application work on the battery cell.

[0066] In this way, the glue sticking device 100 provided in the embodiment of the present application is equipped with at least two glue preparation devices 1 for the glue sticking device 2, and at least two glue preparation devices 1 can alternately provide the cut film C2 to the glue sticking device 2, and the glue sticking device 2 can switch between the glue sticking stations A of each glue preparation device 1 and complete the glue sticking operation on the battery cell, thereby improving the working rhythm of the glue sticking device 2 and the working efficiency of the glue sticking device 100. In addition, since at least two glue preparation devices 1 can work relatively independently, when one of the glue preparation devices 1 stops to change the roll, the other glue preparation devices 1 can continue to provide the cut film C2 to the glue sticking device 2, so that the glue sticking device 100 can still maintain the glue sticking operation when changing the tape, realizing the non-stop tape change of the glue sticking device 100, and further ensuring the production efficiency of the glue sticking device 100 and the entire production line.

[0067] In order to implement the gluing device 100 to glue the two side walls of the battery cell at the same time, in some embodiments, such as Figure 2 As shown, the glue sticking device 100 also includes a cell positioning mechanism 30 for fixing the cell, and each glue preparation device 1 includes two glue preparation mechanisms 10 for providing glue sheets C2 to the glue sticking device 2. The two glue preparation mechanisms 10 are respectively located on both sides of the cell positioning mechanism 30 along the second direction, and the second direction is perpendicular to the first direction. For example, the second direction is Figure 2 in the Y direction.

[0068] In addition, the two glue preparation devices 1 are arranged at intervals along the first direction, and each glue preparation device 1 extends along the second direction as a whole. In order to cooperate with the glue preparation device 1, the glue application station A also extends along the second direction.

[0069] Take the glue sticking equipment 100 including two glue preparation devices 1 as an example, each glue preparation device 1 includes two glue preparation mechanisms 10 arranged along the second direction, that is, one glue sticking equipment 100 includes four glue preparation mechanisms 10, and the two glue preparation mechanisms 10 arranged at intervals along the second direction are located in the same glue sticking station A, and each glue preparation mechanism 10 can cut the film C2 and provide the film C2 to the glue sticking device 2 respectively. Two glue preparation mechanisms 10 arranged at intervals along the second direction form a group and are respectively located on both sides of the battery cell positioning mechanism 30, so as to provide the film C2 for sticking to the two side walls of the battery cell in one glue sticking station A.

[0070] like Figure 2 As shown, the two gluing devices 2 are respectively located on both sides of the battery cell positioning mechanism 30 along the second direction. The gluing devices 2 include a gluing component 21 for picking up and pasting the film C2. The two gluing components 21 can move simultaneously along the first direction to synchronously enter the same gluing station A.

[0071] The two glue sticking components 21 can move simultaneously along the first direction, so as to enter a glue sticking station A at the same time. The glue sticking components 21 pick up and stick the glue C2 to the side wall of the battery cell to ensure the synchronization of gluing the two side walls of the battery cell.

[0072] In this way, each glue preparation device 1 includes two glue preparation mechanisms 10 arranged along the second direction, and the two glue preparation mechanisms 10 can simultaneously provide two glue sheets C2 for the two glue sticking devices 2 to stick the two glue sheets C2 to the two side walls of the battery cell respectively. In this way, when the battery cell passes through a glue sticking station A, the glue sticking device 100 can simultaneously complete the glue sticking operation on the two side walls of the battery cell, further improving the glue sticking efficiency of the glue sticking device 100.

[0073] In order to realize that the glue sticking assembly 21 of the glue sticking device 2 switches positions in at least two glue sticking stations A along the first direction, thereby maintaining a high-beat glue sticking operation, in some embodiments, as Figure 3 As shown, the glue sticking device 2 also includes a glue sticking driving mechanism 22, which is used to drive the glue sticking component 21 to move along a first direction to switch positions between at least two glue sticking stations A. The glue sticking driving mechanism 22 can also drive the glue sticking component 21 to move along a second direction to approach or move away from the battery cell.

[0074] Specifically, the glue sticking driving mechanism 22 is connected to the glue sticking assembly 21, and the glue sticking driving mechanism 22 can drive the glue sticking assembly 21 to move along the second direction to approach the battery cell positioning mechanism 30, so that the glue sticking assembly 21 can stick the film C2 cut by the glue preparation mechanism 10 to the battery cell. When the glue sticking assembly 21 completes the sticking operation of the film C2, the glue sticking driving mechanism 22 drives the glue sticking assembly 21 to return to the initial position along the second direction, so that the glue sticking assembly 21 moves to another glue sticking station A and prepares for the next glue sticking operation, while avoiding interference with the tape C1 pulled out of the glue preparation mechanism 10.

[0075] The glue sticking driving mechanism 22 can also drive the glue sticking assembly 21 to move along the first direction, so that the glue sticking assembly 21 switches positions between the two glue sticking stations A. After the two glue sticking assemblies 21 complete the glue sticking operation at one glue sticking station A, the glue sticking driving mechanism 22 drives the two glue sticking assemblies 21 to move along the first direction to another glue sticking station A, and then the glue sticking driving mechanism 22 continues to drive the glue sticking assembly 21 to move along the second direction at the other glue sticking station A, so that the glue sticking assembly 21 picks up the film C2 and sticks glue to the side wall of the battery cell.

[0076] Optionally, the glue sticking device 2 may further include a control component, which is electrically connected to the glue sticking driving mechanism 22 and can control the glue sticking driving mechanism 22 to operate so as to enable the glue sticking component 21 to move in a controlled manner along the first direction or the second direction.

[0077] In order to realize the glue taking and glue sticking actions of the glue sticking component 21, in some embodiments, as Figure 3 As shown, the glue sticking station A includes a glue taking sub-station a2 and a pasting sub-station a3. The glue taking sub-station a2 and the pasting sub-station a3 are arranged at intervals along the second direction. The pasting sub-station a3 is closer to the battery cell positioning mechanism 30 than the glue taking sub-station a2. The glue sticking driving mechanism 22 can also drive the glue sticking assembly 21 to move along the second direction and pass through the glue taking sub-station a2 and the pasting sub-station a3.

[0078] Specifically, the glue taking substation a2 is configured for the pasting substation a3, and the film C2 cut by the glue preparation mechanism 10 is in the glue taking substation a2, and the glue pasting component 21 needs to move to the glue taking substation a2 to pick up the film C2. The glue pasting equipment 100 includes two glue pasting devices 2, so there are at least two pasting substations a3 and glue taking substation a2, respectively, and they are arranged at intervals along the second direction. In each group of glue taking substation a2 and pasting substation a3, the pasting substation a3 is closer to the battery cell positioning mechanism 30 than the glue taking substation a2, and each glue preparation mechanism 10 is used to provide the film C2 to the glue taking substation a2. After the glue pasting component 21 picks up the film C2 at the glue taking substation a2, the film C2 is pasted to the side wall of the battery cell at the pasting substation a3.

[0079] After the glue sticking driving mechanism 22 drives the glue sticking component 21 to move along the first direction and enter a glue sticking station A, the glue sticking driving mechanism 22 drives the glue sticking component 21 to move along the second direction to pass through the glue taking sub-station a2 and the pasting sub-station a3 in sequence. The glue sticking component 21 picks up the cut film C2 and pastes the film C2 on the side wall of the battery cell.

[0080] In some embodiments, Figure 3 As shown, the gluing station A also includes a position-changing substation a1, and the position-changing substation a1, the glue-removing substation a2 and the adhesive substation a3 are sequentially arranged in intervals along the second direction. When the gluing assembly 21 switches between different gluing stations A along the first direction under the drive of the gluing driving mechanism 22, the gluing assembly 21 is in the position-changing substation a1 in the previous gluing station A, thereby avoiding interference between the gluing assembly 21 and the glue preparation mechanism 10 and the adhesive tape C1.

[0081] The position-changing substation a1 avoids the glue-taking substation a2 along the second direction, so as to avoid the glue-applying component 21 interfering with the adhesive tape C1 when the adhesive preparation mechanism 10 draws the adhesive, resulting in the adhesive preparation mechanism 10 being unable to smoothly cut the adhesive tape C1. After the adhesive preparation mechanism 10 cuts the adhesive tape C1, the adhesive-applying driving mechanism 22 drives the adhesive-applying component 21 to move from the position-changing substation a1 to the glue-taking substation a2 to pick up the adhesive tape C2.

[0082] In order to realize that the glue sticking driving mechanism 22 drives the glue sticking assembly 21 to move, in some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the glue sticking driving mechanism 22 includes a glue sticking telescopic assembly 221 and a glue sticking translation assembly 222. The glue sticking telescopic assembly 221 is connected to the glue sticking assembly 21, and can drive the glue sticking assembly 21 to move along the second direction; the glue sticking translation assembly 222 is connected to the glue sticking telescopic assembly 221, and can drive the glue sticking telescopic assembly 221 to move along the first direction, so that the glue sticking assembly 21 moves between at least two glue sticking stations A.

[0083] The rubber telescopic assembly 221 can be any one of a cylinder drive assembly, a gear rack drive assembly, a pulley drive assembly, or a reciprocating screw assembly. Similarly, the rubber translation assembly 222 can also be any one of a cylinder drive assembly, a gear rack drive assembly, a pulley drive assembly, or a reciprocating screw assembly. The embodiment of the present application does not limit the specific forms of the rubber telescopic assembly 221 and the rubber translation assembly 222.

[0084] In an implementation of the rubber-attached telescopic assembly 221, the rubber-attached telescopic assembly 221 may include a telescopic electric cylinder, which includes a drive motor, a transmission assembly, and a guide rail. The rubber-attached assembly 21 is movably disposed on the guide rail, and the guide rail extends along the second direction. The transmission assembly is connected to the drive motor and the rubber-attached assembly 21 to convert the rotational kinetic energy generated by the drive motor into a driving force for driving the rubber-attached assembly 21 to move along the guide rail, thereby causing the rubber-attached assembly 21 to reciprocate along the second direction.

[0085] Specifically, the driving motor drives the glue sticking assembly 21 to move along the guide rail from the position-changing substation a1 to the glue-taking substation a2. After the glue sticking assembly 21 picks up the film C2, the driving motor drives the glue sticking assembly 21 to move along the guide rail to the pasting substation a3 to paste the film C2. After the glue sticking operation is completed, the glue sticking telescopic assembly 221 drives the glue sticking assembly 21 back to the position-changing substation a1 to prepare to enter the next glue sticking station A to perform glue taking and glue sticking operations.

[0086] The gluing translation assembly 222 is used to drive the gluing telescopic assembly 221 to reciprocate along the first direction. Since the gluing assembly 21 is arranged on the gluing telescopic assembly 221, the gluing translation assembly 222 drives the gluing telescopic assembly 221 to reciprocate along the first direction so that the gluing assembly 21 can switch between at least two gluing stations A.

[0087] In an implementation of the glue-applying translation assembly 222, the glue-applying translation assembly 222 may include a driving member 2221 and a guiding member 2222. The driving member 2221 is connected to the glue-applying telescopic assembly 221; the guiding member 2222 extends along the first direction, and the glue-applying telescopic assembly 221 is movably disposed on the guiding member 2222, and the guiding member 2222 is used to guide the movement of the glue-applying telescopic assembly 221.

[0088] Optionally, the driving member 2221 may be a motor, a cylinder or a motor. The guiding member 2222 may be a slide rail and extends along the first direction so that the adhesive telescopic assembly 221 keeps reciprocating along the first direction.

[0089] In order to realize the function of the adhesive sticking component 21 picking up and sticking the film C2, in some embodiments, as Figure 3 As shown, the glue sticking assembly 21 includes a clamping claw cylinder 211, a first suction cup 212 and a second suction cup 213. The clamping claw cylinder 211 is arranged on the glue sticking driving mechanism 22.

[0090] Specifically, the clamping claw cylinder 211 is arranged on the guide rail in the glue sticking telescopic assembly 221, and can slide along the guide rail under the drive of the driving motor. The clamping claw of the clamping claw cylinder 211 is provided with a first suction cup 212 and a second suction cup 213, and the first suction cup 212 and the second suction cup 213 are arranged at intervals along the height direction of the glue sticking device 100, so as to adsorb the two ends of the film C2.

[0091] The clamping claws of the clamping claw cylinder 211 are respectively connected to the first suction cup 212 and the second suction cup 213, so that the clamping claw cylinder 211 can adjust the distance between the first suction cup 212 and the second suction cup 213 along the height direction (Z direction) of the glue sticking device 100, so that the first suction cup 212 and the second suction cup 213 can maintain the two ends of the film C2. In this way, when the glue sticking device 100 is used for glue sticking different battery cell models, the length of the film C2 cut by the glue preparation mechanism 10 changes accordingly, and the clamping claw cylinder 211 adjusts the distance between the first suction cup 212 and the second suction cup 213, so that the first suction cup 212 and the second suction cup 213 can stably absorb the two ends of the film C2 of different lengths, thereby improving the adaptability and versatility of the glue sticking assembly 21.

[0092] In addition, the first suction cup 212 and the second suction cup 213 have adsorption force to stably adsorb and move the film C2. At the same time, the first suction cup 212 and the second suction cup 213 use the adsorption force to pick up the film C2, which causes less damage to the film C2 and is beneficial to protecting the integrity and bonding strength of the film C2.

[0093] In order to enable the film preparation mechanism 10 to cut the film C2 of a preset length, in some embodiments, for example Figure 6 As shown, the glue assembly mechanism 10 includes: an unwinding reel 101, which is used to output the adhesive tape C1; a glue fixing component 102, which is used to guide and clamp the adhesive tape C1 output from the unwinding reel 101; a glue pulling component 103, which can clamp the free end of the adhesive tape C1 output from the glue fixing component 102 and pull the adhesive tape C1 into the glue taking sub-station a2; a glue cutting component 104, which is located between the glue fixing component 102 and the glue pulling component 103, and is used to cut the adhesive tape C1 clamped by the glue fixing component 102 and the glue pulling component 103 to form a film C2.

[0094] Specifically, the unwinding reel 101 is used to install the tape roll. When the tape roll is about to run out, the adhesive preparation device 1 needs to be shut down, and the operator replaces the tape roll in the unwinding reel 101, removes the old tape roll and installs a new tape roll.

[0095] The adhesive fixing assembly 102 is used to guide the adhesive tape C1 output from the unwinding reel 101, so that the adhesive tape C1 is stably transmitted along a preset path and the tightness of the adhesive tape C1 during transmission is ensured. The adhesive pulling assembly 103 is used to clamp the free end of the adhesive tape C1 output from the adhesive fixing assembly 102, and then pull the adhesive tape C1 away from the unwinding reel 101, and pull at least part of the adhesive tape C1 into the above-mentioned adhesive sub-station a2.

[0096] It should be noted that the stretching length of the tape C1 by the glue pulling component 103 can be determined according to the model of the battery cell. The longer the required film C2 size is, the greater the distance that the glue pulling component 103 can move away from the unwinding reel 101 can be, so as to pull out a sufficiently long tape C1 from the unwinding reel 101.

[0097] When the glue pulling component 103 pulls the adhesive tape C1 to the required length, the glue setting component 102 clamps the adhesive tape C1, and the adhesive tape C1 is clamped by the glue setting component 102 and the glue pulling component 103 respectively. The glue cutting component 104 located between the glue setting component 102 and the glue pulling component 103 can cut the adhesive tape C1 to form the above-mentioned adhesive film C2. After the glue sticking component 21 absorbs the adhesive film C2 at the adhesive taking sub-station a2, the glue pulling component 103 can release the adhesive film C2, and the glue sticking driving mechanism 22 drives the glue sticking component 21 to move along the second direction to the adhesive sticking sub-station a3 to complete the glue sticking operation of the battery cell.

[0098] The adhesive cutting component 104 may include a cutter, and the cutter can move along the second direction, so as to cut the adhesive tape C1 between the adhesive setting component 102 and the adhesive pulling component 103 into adhesive sheets C2 of a preset length.

[0099] In some embodiments, Figure 2 and Figure 6 As shown, the glue laminating device 100 includes a support plate 40, which is used to support components such as the unwinding reel 101, the glue fixing assembly 102 and the glue cutting assembly 104. Therefore, the support plate 40 has a certain structural strength and can be made of a material with a certain supporting force.

[0100] Furthermore, the unwinding reel 101, the glue setting assembly 102 and the glue cutting assembly 104 are arranged on one side of the support plate 40, and the glue pulling assembly 103, the glue sticking device 2 and the battery cell positioning mechanism 30 are arranged on the other side of the support plate 40. In this way, the space layout of the glue sticking equipment 100 can be reasonably utilized, making the glue sticking equipment 100 more compact and miniaturized, thereby improving the space utilization rate of the entire production line.

[0101] In order to realize the positioning and guiding of the adhesive tape C1 by the adhesive preparation device 1, as shown in FIG. Figure 6As shown, the glue fixing component 102 includes: a glue preparation component 1021, which includes a plurality of guide rollers 10211 for guiding the adhesive tape C1 and arranged at intervals; a glue changing lifting component 1022, which is connected to the unwinding disk 101 and can drive the unwinding disk 101 to perform a lifting action; and a glue fixing jaw 1023, which is arranged on the glue changing lifting component 1022, and the glue fixing jaw 1023 can allow the adhesive tape C1 to pass through and clamp part of the adhesive tape C1.

[0102] The adhesive preparation member 1021 may include a support rod 10212, and the support rod 10212 is arranged on the support plate 40 to ensure the stability of the support rod 10212. A plurality of guide rollers 10211 are arranged at intervals on the support rod 10212, and the guide rollers 10211 can rotate relative to the support rod 10212 through bearings. After the adhesive tape C1 is output from the unwinding disk 101, it is passed between the plurality of guide rollers 10211. The setting positions and spacings of the plurality of guide rollers 10211 ensure the stability and directionality of the adhesive tape C1 during the transmission process, and can also ensure that the adhesive tape C1 has a suitable tightness.

[0103] The glue changing lifting member 1022 is also arranged on the support plate 40. The glue changing lifting member 1022 can drive the unwinding disk 101 to move up and down. In this way, when the glue preparation device 1 needs to stop for reel change, the glue changing lifting member 1022 can drive the unwinding disk 101 to move up and down to facilitate the replacement of a new tape roll.

[0104] The glue fixing jaw 1023 is arranged on the base 1037 of the glue changing lifting member 1022, that is, the glue changing lifting member 1022 provides structural support and positioning for the glue fixing jaw 1023, so that the position of the glue fixing jaw 1023 relative to the unwinding disk 101 can be relatively fixed, and the adhesive tape C1 can be output from a fixed position to the glue drawing component 103 after being guided by the glue preparation component 1021. At the same time, the position of the glue fixing jaw 1023 is fixed, and it can also ensure that the glue fixing jaw 1023 corresponds to the jaw of the glue drawing component 103 in the height direction, thereby ensuring the verticality of the glue drawing.

[0105] When the adhesive pulling component 103 pulls the adhesive tape to a required length, the adhesive fixing jaws 1023 can clamp the adhesive tape C1 , so that the adhesive cutting component 104 can subsequently perform an adhesive cutting operation on the adhesive tape C1 clamped at both ends.

[0106] In order to realize the glue pulling function of the glue pulling component 103, in some embodiments, as Figure 7 , Figure 8 and Fig. 9As shown, the glue pulling component 103 includes a bracket 1031; a lifting slide rail, which is arranged on the bracket 1031, and the lifting slide rail includes a first sliding part 10321 that can be lifted and lowered relative to the bracket 1031; a glue pulling clamp 1033, which is connected to the first sliding part 10321, and the first sliding part 10321 drives the glue pulling clamp 1033 to approach or move away from the glue fixing component 102 to take glue and stretch the tape C1.

[0107] Specifically, the bracket 1031 extends along the height direction of the adhesive laminating device 100. The lifting assembly 1032 is disposed on the bracket 1031, and the lifting assembly 1032 includes a first sliding portion 10321, which can be lifted relative to the bracket 1031, and the adhesive pulling clamp 1033 is disposed on the first sliding portion 10321 to be lifted along with the first sliding portion 10321.

[0108] Optionally, the lifting assembly 1032 may further include a lifting rail 10322 and a glue pulling cylinder 1035, the lifting rail 10322 extends along the height direction of the glue laminating device 100, and the first sliding part 10321 may be slidably matched with the lifting rail 10322. The glue pulling cylinder 1035 is connected to the first sliding part 10321 to drive the first sliding part 10321 to reciprocate on the lifting rail 10322.

[0109] Exemplarily, when the glue pulling component 103 needs to pull glue, the glue pulling cylinder 1035 drives the first sliding part 10321 to move along the lifting rail 10322 in the direction close to the glue fixing jaw 1023, so that the glue pulling jaw 1033 clamps the free end of the adhesive tape C1 from the glue fixing jaw 1023. Then the glue clamping cylinder makes the glue pulling jaw 1033 clamp the adhesive tape C1, and the glue pulling cylinder 1035 drives the first sliding part 10321 to move along the lifting rail 10322 in the direction away from the adhesive fixing jaw 1023 to pull the adhesive tape C1 out of the unwinding disk 101. When the adhesive tape C1 is pulled out to a suitable length, the glue pulling cylinder 1035 stops working, and the glue pulling jaw 1033 remains in this position, so that the subsequent glue cutting component 104 can perform glue cutting operations.

[0110] In order to ensure the stability of the movement of the first sliding part 10321 along the lifting rail 10322, in some embodiments, as Figure 7 and Fig. 9 As shown, the glue pulling assembly 103 also includes: two limiting buffer components 1034, which are arranged on the bracket 1031, and the two limiting buffer components 1034 are respectively located at two ends of the moving path of the first sliding part 10321 to buffer and limit the first sliding part 10321.

[0111] It can be understood that the first sliding part 10321 reciprocates along the lifting rail 10322 to drive the glue pulling claw 1033 to take and pull the glue, so the moving path of the first sliding part 10321 can limit the glue pulling length of the glue pulling component 103, thereby ensuring that the glue C2 of the preset length is obtained. The limiting buffer components 1034 set at both ends of the first sliding part 10321 can not only limit the stroke of the first sliding part 10321, so that the glue pulling length is within a controllable range, but also the limiting buffer components 1034 can buffer the movement of the first sliding part 10321 to prevent the first sliding part 10321 from having hard contact with other components when moving to the extreme position, thereby generating an impact force on the structural parts in the glue sticking device 100.

[0112] Each limiting buffer member 1034 includes a limiting member 10341 and a buffer member 10342 arranged at intervals, the limiting member 10341 and the buffer member 10342 both extend along the height direction of the glue laminating device 100, and the limiting member 10341 and the buffer member 10342 can be arranged at intervals along the first direction. The free end of the limiting member 10341 is farther away from the first sliding portion 10321 than the free end of the buffer member 10342.

[0113] Exemplarily, two position-limiting buffer members 1034 may be respectively arranged on the bracket 1031 or the lifting rail 10322 , wherein the free ends of one group of position-limiting buffer members 1034 face upward, and the free ends of one group of position-limiting buffer members 1034 face downward.

[0114] When the first sliding part 10321 moves toward the glue fixing assembly 102 on the lifting rail 10322 and is about to reach the glue taking position, the buffer 10342 with the free end facing downward abuts against the first sliding part 10321; when the first sliding part 10321 moves away from the glue fixing assembly 102 on the lifting rail 10322 and is about to reach the glue pulling position, the buffer 10342 with the free end facing upward abuts against the first sliding part 10321. In this way, the impact force and vibration between the first sliding part 10321 and the bracket 1031 or the lifting rail 10322 can be reduced, and a stable buffering effect can be achieved.

[0115] It can be understood that the free end of the limiting member 10341 is farther away from the first sliding part 10321 than the free end of the buffer member 10342. If the first sliding part 10321 continues to slide after abutting against the buffer member 10342, it will be limited by the limiting member 10341. Therefore, the limiting member 10341 can further ensure that the first sliding part 10321 is within a controllable sliding stroke.

[0116] In order to facilitate daily cleaning and maintenance of the glue pulling assembly 103, in some embodiments, as Figure 8 and Fig. 9As shown, the glue pulling assembly 103 also includes: a base 1037; a fixed plate 1038, the bracket 1031 is arranged on the fixed plate 1038, and the fixed plate 1038 is movably arranged on the base 1037; a translation driving member, which is arranged on the base 1037, and the translation driving member 1039 can drive the fixed plate 1038 to reciprocate along the first direction.

[0117] The base 1037 can extend in the horizontal direction, and a translation linear rail 10392 extending in the first direction is provided on the base 1037. The fixed plate 1038 is movably provided on the base 1037 through the translation linear rail 10392, and can reciprocate in the first direction relative to the base 1037. In addition to the translation linear rail 10392, the translation driving member 1039 also includes a translation cylinder 10391, the driving end of the translation cylinder 10391 is connected to the fixed plate 1038, and the translation cylinder 10391 is used to provide a driving force for the fixed plate 1038 to reciprocate in the first direction.

[0118] When it is necessary to perform routine maintenance on the glue pulling assembly 103, the fixed plate 1038 can be pushed out along the first direction by the translation driving member 1039, and the glue pulling clamp 1033 and the limit buffer member 1034 provided on the bracket 1031 are all moved along the first direction to a maintenance area with relatively sufficient space along with the fixed plate 1038, so that the operator can perform routine maintenance on the glue pulling clamp 1033, for example, replacing the granular glue on the glue pulling clamp 1033. In this way, the inconvenience of daily maintenance of the glue pulling assembly 103 caused by the space limitation of the glue pulling area can be avoided, so that the glue sticking device 100 has sufficient safe maintenance space.

[0119] In some embodiments, Fig.10 and Fig.11 As shown, the glue laminating equipment 100 also includes a battery cell positioning mechanism 30 including: a positioning cylinder 301, the output end of the positioning cylinder 301 can be extended and retracted along the second direction; a connecting plate 302, connected to the output end of the positioning cylinder 301; a positioning gauge 303, used to clamp the battery cell, and the positioning gauge 303 is arranged on the connecting plate 302.

[0120] Specifically, the battery cell positioning mechanism 30 can be set on the support plate 40 and used to fix the battery cell transported from the conveyor belt. The battery cell positioning mechanism 30 is located in the middle area of ​​the gluing equipment 100 along the second direction, so that the gluing device 2 located on both sides of the battery cell positioning mechanism 30 can glue the side walls of the battery cell.

[0121] The battery cell positioning mechanism 30 includes two connecting plates 302 and a positioning cylinder 301 . The driving end of the positioning cylinder 301 is connected to a connecting plate 302 . A positioning gauge 303 is provided on each connecting plate 302 . The two positioning gauges 303 are used to abut against the battery cells.

[0122] By driving a connecting plate 302 to move closer to or away from another connecting plate 302 through the positioning cylinder 301, the distance between the two positioning regulating parts 303 can be adjusted, so that the position of the battery cells picked up from the conveyor belt can be regulated. The battery cells are in the regulated state to ensure the accuracy of the gluing position and the quality of the gluing of the battery cells.

[0123] like Fig.12 and Fig.13 As shown, the second aspect of the embodiment of the present application discloses a glue laminating system 200, and the glue laminating system 200 includes a glue laminating device 100 as described in any of the above embodiments.

[0124] It can be understood that the glue laminating system 200 using the glue laminating device 100 of the above embodiment has all the technical effects of the glue laminating device 100 of the above embodiment, which will not be described in detail here.

[0125] In order to improve the overall gluing efficiency of the gluing system 200, and to ensure that the entire gluing system 200 does not stop when the glue preparation device 1 of one of the gluing devices 100 changes the tape, and can continuously perform gluing operations on a group of battery cells, in some embodiments, the gluing devices 100 in the gluing system 200 are configured to be at least four, at least four gluing devices 100 are arranged along a first direction, and at least four gluing devices 100 are used to glue at least four battery cells.

[0126] It should be noted that in the scenario of bundling and pairing battery cells, four battery cells are usually grouped together, so the embodiment of the present application takes four gluing devices 100 to glue four battery cells as an example for explanation, but it does not mean that the embodiment of the present application limits the number of battery cells. The number of gluing devices 100 configured in the gluing system 200 can be adjusted according to the actual needs of the production line and the number of battery cells in a group of battery cells. The at least four gluing devices 100 configured in the gluing system 200 include a first gluing device 100a, a second gluing device 100b, a third gluing device 100c, and a fourth gluing device 100d.

[0127] Furthermore, the four gluing devices 100 are arranged at intervals along the first direction, which further ensures the compactness of the gluing system 200, reduces the space requirement of the gluing system 200, and realizes the arrangement of the gluing system 200 in a limited space.

[0128] The first gluing device 100a, the second gluing device 100b, the third gluing device 100c and the fourth gluing device 100d are used to perform gluing operations on the second battery cell, the fourth battery cell, the first battery cell and the fourth battery cell respectively. In the first direction of transmission of the conveyor belt, the first battery cell, the second battery cell, the third battery cell and the fourth battery cell are arranged in sequence. In this way, the gluing system 200 can perform continuous gluing operations on at least four battery cells in a group of battery cells by configuring at least four gluing devices 100, thereby improving the gluing efficiency of the gluing system 200.

[0129] Furthermore, the four gluing devices 100 perform gluing operations on the battery cells at intervals in order to ensure that the spacing between adjacent gluing devices 100 matches the spacing between the corresponding battery cells.

[0130] Exemplarily, the distance between the first gluing device 100a and the second gluing device 100b can be adapted to the distance between the second battery cell and the fourth battery cell. In this way, when the conveyor belt is at a preset transmission speed, a group of battery cells are transmitted along the first direction. When passing through the first gluing device 100a, the second battery cell corresponds to the first gluing device 100a. When the group of battery cells continues to be transmitted and passes through the second gluing device 100b, the fourth battery cell corresponds to the second gluing device 100b, so that the gluing device 100 performs the gluing operation for the corresponding battery cell.

[0131] In addition, the four glue sticking devices 100 perform glue sticking operations on the second battery cell, the fourth battery cell, the first battery cell, and the third battery cell at intervals, respectively, so that when some of the glue preparation devices 1 in the four glue sticking devices 100 are stopped for tape change operations, a certain glue sticking device 100 can continuously stick glue to two adjacent battery cells, thereby improving the glue sticking rhythm and efficiency. For details, see the detailed description of how the glue sticking system 200 sticks glue to four battery cells when the glue sticking system 200 is stopped for tape change operations below.

[0132] As described above, each glue laminating device 100 includes two glue laminating stations A, and the four glue laminating devices 100 are arranged along the first direction, so the glue laminating system 200 includes eight glue preparation devices 1 and eight glue laminating stations A arranged along the first direction. In order to ensure the safety when the glue preparation device 1 is changed, the glue laminating system 200 provided in the embodiment of the present application divides the above eight glue preparation devices 1 and eight glue laminating stations A into three independent tape changing areas, and provides an isolation protective cover 50 for each tape changing area, so as to meet the safety requirements of the glue laminating system 200 when changing tapes.

[0133] Specifically, the glue laminating system 200 includes three tape changing areas, namely the first tape changing area B1, the second tape changing area B2 and the third tape changing area B3, wherein the first glue laminating station A1 and the second glue laminating station A2 of the first glue laminating device 100a and the third glue laminating station A3 of the second glue laminating device 100b are located in the first tape changing area B1, the fourth glue laminating station A4 of the second glue laminating device 100b and the fifth glue laminating station A5 of the third glue laminating device 100c are located in the second tape changing area B2, and the sixth glue laminating station A6 of the third glue laminating device 100c and the seventh glue laminating station A7 and the eighth glue laminating station A8 of the fourth glue laminating device 100d are located in the third tape changing area B3.

[0134] When it is necessary to perform a tape change operation on the glue preparation device 1 in the first tape change area B1, the control device of the glue laminating system 200 shuts down the first glue laminating device 100a in the first tape change area B1, and controls the second glue laminating device 100b and the glue preparation device 1 corresponding to the third glue laminating station A3 to shut down, and the glue laminating device 2 in the second glue laminating device 100b moves to the fourth glue laminating station A4 in the second tape change area B2 to perform a glue laminating operation. At this time, all the glue preparation devices 1 in the first tape change area B1 are in a shutdown and power-off state, ensuring the safety of the operator when performing the tape change operation.

[0135] At the same time, although all the glue preparation devices 1 in the first tape changing area B1 are shut down for tape changing, the glue sticking equipment 100 does not shut down. Specifically, when all the glue preparation devices 1 in the first tape changing area B1 are powered off and shut down, the control device controls the conveyor belt to slow down. At this time, the glue sticking device 2 of the second glue sticking equipment 100b can stick glue to the fourth battery cell at the fourth glue sticking station A4, the glue sticking device 2 of the third glue sticking equipment 100c can stick glue to the first battery cell at the fifth glue sticking station A5 or the sixth glue sticking station A6, and the fourth glue sticking equipment 100d can stick glue to the adjacent second battery cell and the third battery cell continuously at the seventh glue sticking station A7 or the eighth glue sticking station A8. The fourth glue sticking equipment 100d does not need to stick glue to the two separated battery cells, thereby reducing the waiting time and improving the efficiency of the glue sticking operation. Thereby, the glue sticking system 200 can change the tape of part of the glue preparation device 1 without stopping, and keep sticking glue to multiple battery cells continuously.

[0136] Similarly, when it is necessary to perform a tape change operation on the glue preparation device 1 in the second tape change area B2, the control device of the glue system 200 shuts down the glue preparation device 1 corresponding to the second glue device 100b and the fourth glue station A4 in the second tape change area B2, and shuts down the glue preparation device 1 corresponding to the third glue device 100c and the fifth glue station A5, moves the glue device 2 in the second glue device 100b to the third glue station A3 in the first tape change area B1 to perform a glue operation on the fourth battery cell, and moves the glue device 2 in the third glue device 100c to the sixth glue station A6 in the third tape change area B3 to perform a glue operation on the first battery cell. At this time, all the glue preparation devices 1 in the second tape change area B2 are in a shutdown and power-off state, ensuring the safety of the operator when performing tape change operations.

[0137] At the same time, although all the glue preparation devices 1 in the second tape changing area B2 are shut down for tape changing, the glue sticking equipment 100 does not shut down. Specifically, when all the glue preparation devices 1 in the second tape changing area B2 are powered off and shut down, and the conveyor belt does not need to slow down. At this time, the glue sticking device 2 of the second glue sticking equipment 100b can glue the fourth battery cell at the third glue sticking station A3, and the glue sticking device 2 of the third glue sticking equipment 100c can glue the first battery cell at the sixth glue sticking station A6. The first glue sticking equipment 100a and the fourth glue sticking equipment 100d can glue the second battery cell and the third battery cell normally. Not only does the glue sticking system 200 change the tape of part of the glue preparation device 1 without stopping, but the transmission speed of the conveyor belt remains unchanged, so that the glue sticking efficiency of the glue sticking system 200 is not reduced due to tape changing.

[0138] Similarly, when it is necessary to perform a tape change operation on the glue preparation device 1 in the third tape change area B3, the control device of the glue laminating system 200 shuts down the fourth glue laminating device 100d in the third tape change area B3, shuts down the glue preparation device 1 corresponding to the third glue laminating device 100c and the sixth glue laminating station A6, and moves the glue laminating device 2 in the third glue laminating device 100c to the fifth glue laminating station A5 in the second tape change area B2 for glue laminating operation. At this time, all the glue preparation devices 1 in the third tape change area B3 are in a shutdown and power-off state, ensuring the safety of the operator when performing tape change operations.

[0139] At the same time, although all the glue preparation devices 1 in the third tape changing area B3 are shut down for tape changing, the glue sticking equipment 100 does not shut down. Specifically, when all the glue preparation devices 1 in the third tape changing area B3 are powered off and shut down, the control device controls the conveyor belt to slow down. At this time, the glue sticking device 2 of the third glue sticking equipment 100c can stick glue to the first battery cell at the fifth glue sticking station A5, the glue sticking device 2 of the second glue sticking equipment 100b can stick glue to the fourth battery cell at the third glue sticking station A3 or the fourth glue sticking station A4, and the first glue sticking equipment 100a can stick glue to the adjacent second battery cell and the third battery cell continuously at the first glue sticking station A1 or the second glue sticking station A2. The first glue sticking equipment 100a does not need to stick glue to the two separated battery cells, thereby reducing the waiting time and improving the efficiency of the glue sticking operation. The glue sticking system 200 is implemented to change the tape of part of the glue preparation device 1 without stopping, and to keep sticking glue to multiple battery cells continuously.

[0140] In some embodiments, the glue laminating system 200 further includes a conveyor belt for transporting the battery cells, and the conveyor belt passes through the multiple glue laminating devices 100 of the glue laminating system 200, so that the battery cells to be glued pass through the multiple glue laminating devices 100 and complete the glue laminating.

[0141] The conveyor belt extends along the first direction, and the battery cell positioning mechanism 30 of each glue laminating device 100 is arranged corresponding to the conveyor belt to facilitate the battery cell to enter the battery cell positioning mechanism 30 .

[0142] In order to ensure the safety of the tape changing of the adhesive laminating system 200, in some embodiments, as Fig.12 As shown, the glue laminating system 200 further includes a protective cover 50 , and the plurality of protective covers 50 are respectively used to isolate the first tape changing area B1 , the second tape changing area B2 , and the third tape changing area B3 .

[0143] The protective cover 50 is used to achieve electrical isolation between the first tape-changing area B1, the second tape-changing area B2 and the third tape-changing area B3, so as to ensure that the adhesive preparation devices 1 in each tape-changing area can be powered off and tape-changed independently of each other. A plurality of isolation plates can be arranged around a tape-changing area, that is, a plurality of isolation plates are arranged around a tape-changing area in the front and back and left and right directions, so as to safely and reliably electrically isolate the first tape-changing area B1, the second tape-changing area B2 and the third tape-changing area B3.

[0144] In some embodiments, each protective cover 50 includes a safety door lock and an unlocking button for unlocking the safety door lock. Each protective cover 50 includes a safety door lock and an unlocking button, which can further ensure that only authorized operators can perform a tape change operation on the glue sticking system 200, thereby further ensuring the safety of tape change of the glue sticking system 200.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
