[0004] In the entire production process of a battery, one or more stations are involved in adhesive application to the battery, such as adhesive application to the corner of a pole piece and to the tab of a pole piece to reduce the probability of contact short circuit between adjacent pole pieces, or direct adhesive application to the surface of a battery to protect the surface of the battery by the adhesive film.

[0005] In the adhesive application equipment for a battery, the adhesive tape is generally stored in the form of a roll on a reel, and the roll on the reel needs to be pulled out to a predetermined length and cut off to obtain a small piece of adhesive film for pasting to the corresponding part of the battery.

[0014] The adhesive tape preparation device has at least the following beneficial effects:

[0015] In some embodiments, the driving member has an extension shaft connected to the first over roller, the extension shaft is extended when the adhesive tape is fixed by the pressing mechanism, and the extension shaft is retracted when the pulling mechanism pulls the adhesive tape.

[0016] In this way, the preset length of the adhesive tape is stored, and the tension on the adhesive tape is maintained within a stable range during the pulling process, thereby reducing the probability of wrinkles and tears caused by relaxation and excessive tension of the adhesive tape.

[0018] In this way, the driving force of the extension shaft of the driving member on the first over roller and / or the adhesive tape is effectively reduced, thereby reducing the risk of tearing and breaking of the adhesive tape.

[0019] In some embodiments, the driving member is configured as a pneumatic execution structure, the adjusting member is configured as an electrical proportional valve in communication with the driving member, and the adjusting member is arranged at an air inlet end of the driving member to adjust the air inlet pressure or air outlet pressure of the air inlet end.

[0020] In this way, the electric proportional valve adjusts the air inlet pressure or the air outlet pressure of the air inlet end of the driving member to adjust the driving force of the telescopic shaft on the adhesive tape, effectively reducing the risk of tearing and breaking of the adhesive tape due to excessive tension change.

[0021] In some embodiments, the driving member has a piston cavity, the telescopic shaft is movably arranged in the piston cavity, and the adjusting member is arranged at the air inlet end of the piston cavity.

[0022] The adjusting member is used to input a first preset air pressure into the piston cavity when the adhesive tape is fixed by the pressing member, so that the telescopic shaft drives the first passing roller to move from the first position to the second position.

[0023] In addition, the adjusting member is also used to release the pressure of the piston cavity when the adhesive tape is pulled by the pulling mechanism.

[0024] In this way, the adhesive tape on the adhesive disc is continuously outputted with a preset length, and the tension on the adhesive tape is maintained within a stable range, effectively reducing the probability of wrinkling and tearing of the adhesive tape due to relaxation and excessive tension during the pulling process of the adhesive tape roll, and improving the smoothness and stability of the adhesive tape.

[0025] In some embodiments, the adhesive opening mechanism further comprises a sliding rail and a sliding block slidingly installed on the sliding rail, the first passing roller is rotatably arranged on the sliding block, and the driving end of the driving member is connected to the sliding block.

[0031] In some embodiments, the adhesive storage mechanism further comprises a detector configured to detect the winding radius of the adhesive tape on the adhesive disc, and send an alarm signal when the winding radius of the adhesive tape is less than a preset radius.

[0035] The gluing device of the application has the same technical effects as the adhesive preparation device, i.e., through the cooperation of the adhesive storage mechanism, the adhesive opening mechanism and the adhesive pulling mechanism, the change in tension caused by the movement of the first roller is balanced by the change in tension caused by the decrease in the winding radius of the adhesive tape on the adhesive disc during the process in which the driving member of the adhesive opening mechanism drives the first roller to move towards the direction of tensioning the adhesive tape to pull out the adhesive tape on the adhesive disc to a preset length; and the adhesive pulling mechanism does not cause large changes in tension of the adhesive tape during the process in which the adhesive tape is pulled out to the preset length relative to the pressing member. In this way, the tension of the adhesive tape can be maintained within a stable range during the output of the adhesive tape on the adhesive disc, effectively reducing the probability of wrinkles and tears caused by relaxation and excessive tension during the pulling out of the adhesive tape, improving the smoothness and stability of the adhesive tape, and enabling the adhesive preparation device to stably complete the adhesive preparation and adhesive supply actions, thereby improving the efficiency of gluing the corresponding parts of the battery and the production efficiency of the battery.

[0052] At present, from the development of market situation, the application of battery is more and more widely. The battery is not only applied to the energy storage power supply system of hydropower, thermal power, wind power and solar power station, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of battery, the demand of its market is also increasing.

[0053] The battery is composed of one or more battery monomers. For each battery, the plurality of battery monomers constituting it can be connected in series or in parallel or in mixed connection. Among them, mixed connection means that there are series connection and parallel connection in the plurality of battery monomers.

[0054] The battery monomer is the smallest unit to constitute the battery, and in the structure of the battery monomer, it includes the shell, the electrolyte and the electrode assembly. The electrode assembly is the component where the electrochemical reaction occurs in the battery monomer, and the electrode assembly includes the positive plate, the negative plate and the separator. The shell can include one or more electrode assemblies, and the electrode assembly is mainly formed by winding or stacking the positive plate and the negative plate, and the separator is usually arranged between the positive plate and the negative plate.

[0055] The housing is an open-end, hollow structure. The electrode assembly is disposed inside the housing, and an end cap is placed over the opening. By closing the opening with the end cap, the internal environment of the battery cell is formed. Alternatively, the end cap and housing can be integrated. In some embodiments, the end cap and housing can form a common connection surface before other components are inserted into the housing. When it is necessary to encapsulate the interior of the housing, the end cap is then closed. The housing can have various shapes and sizes, such as cuboid, cylindrical, hexagonal prism, etc. In some embodiments, the shape of the housing can be determined according to the specific shape and size of the electrode assembly. The housing can be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this application does not impose any special limitations on these materials.

[0056] Throughout the battery production process, there are one or more workstations that involve applying adhesive to the battery, such as applying adhesive to the corners of the electrode sheets and to the tabs of the electrode sheets, to reduce the probability of short circuits caused by contact between adjacent electrode sheets; or applying adhesive directly to the surface of the battery to protect the battery surface with the adhesive film, etc.

[0057] In battery adhesive application equipment, the tape is usually stored in roll form on a spool. The roll needs to be pulled out to a preset length and then cut to obtain a small piece of tape for pasting to the corresponding part of the battery.

[0058] In related technologies, as the tape roll on the reel is pulled out, the winding radius of the tape roll continuously decreases, causing the tension on the pulled-out tape to change continuously, increasing the risk of tape wrinkling and tearing, resulting in poor smoothness and stability of tape delivery.

[0059] Based on this, addressing the problem of wrinkling and tearing during the pulling process of adhesive tape rolls, resulting in poor smoothness and stability of the tape, one or more embodiments of this application provide a glue preparation device. Through the coordinated arrangement of a glue storage mechanism, a glue opening mechanism, and a glue pulling mechanism, the drive component in the glue opening mechanism moves the first guide roller towards the direction of tensioning the tape to pull the tape from the reel to a preset length. The tension change caused by the movement of the first guide roller on the tape is roughly balanced by the tension change caused by the reduction in the tape's winding radius on the reel. The glue pulling mechanism does not cause significant tension changes to the tape during the pulling process relative to the pressure component. Thus, the tension on the tape is maintained within a stable range during tape output from the reel, effectively reducing the probability of wrinkling and tearing caused by excessive slack or tension during the pulling process. This improves the smoothness and stability of the tape, enabling the glue preparation device to stably complete the glue preparation and supply operations, thereby improving the efficiency of applying adhesive to corresponding parts of the battery and consequently increasing battery production efficiency.

[0060] Referring to FIG. 1, FIG. 2 and FIG. 3, the embodiment of the present application provides a glue preparation device, which comprises a glue storage mechanism 100, a glue opening mechanism 200 and a glue pulling mechanism 300.

[0061] The glue storage mechanism 100 comprises a glue disc 110 for winding the adhesive tape 400, and the glue disc 110 is capable of rotating around its own axis.

[0062] The glue opening mechanism 200 comprises a driving member 210, a first passing roller 220 and a glue pressing member 230, the adhesive tape 400 is wound around the first passing roller 220 and is turned at the first passing roller 220 to extend to the glue pressing member 230 to be fixed by the glue pressing member 230, and the driving member 210 is used to drive the first passing roller 220 to move towards the direction of tensioning the adhesive tape 400 when the adhesive tape 400 is fixed by the glue pressing member 230, so as to pull out the adhesive tape 400 on the glue disc 110 by a preset length.

[0063] The glue pulling mechanism 300 is used to pull the adhesive tape 400 to move along the first direction X when the adhesive tape 400 is released by the glue pressing member 230, so as to pull out the adhesive tape 400 by a preset length relative to the glue pressing member 230.

[0064] It should be noted that the glue storage mechanism 100 refers to the mechanism capable of storing or storing the adhesive tape in the form of roll stock. The glue disc 110 on the glue storage mechanism 100 can be but is not limited to a component capable of rotating around its own axis, such as a reel, a spool and the like. The glue disc 110 is driven by an external force source and can rotate around its own axis. The external force source can be a motor, an electric motor or other rotating driving member in transmission connection with the glue disc 110, or can be a pulling force acting on the adhesive tape 400, or can be other structure capable of driving the glue disc 110 to rotate around itself.

[0065] The glue opening mechanism 200 refers to the component capable of pulling out the adhesive tape 400 on the glue disc 110 by a preset length, and capable of maintaining the tension of the adhesive tape 400 stable during the process of pulling out the adhesive tape 400 by a preset length.

[0066] In the glue opening mechanism 200, the driving member 210 and the first passing roller 220 can be installed on the frame 500 of the glue preparation device. The first passing roller 220 is freely rotatable, and the driving member 210 can be a pneumatic cylinder, a hydraulic cylinder, an electric push rod or the like. In some embodiments, the driving member 210 is configured as a pneumatic cylinder with a telescopic shaft 211, the telescopic shaft 211 of the driving member 210 is connected with the first passing roller 220, and the telescopic shaft 211 of the driving member 210 drives the first passing roller 220 to move through the telescopic mode.

[0067] In the glue opening mechanism 200, the glue pressing member 230 can be a clamping cylinder, which can fix or loosen the adhesive tape 400 by clamping or releasing the adhesive tape 400. Of course, in other examples, the glue pressing member 230 can also include a pressing part and a supporting part oppositely arranged on the frame 500 of the glue preparation device, and a glue passing channel for the adhesive tape 400 to pass through is formed between the pressing part and the supporting part, and the extension direction of the glue passing channel corresponds to the first direction X in the embodiment of the application. The pressing part can move towards or away from the supporting part to fix or loosen the adhesive tape 400.

[0068] It can be understood that the first passing roller 220 and the glue pressing member 230 of the glue opening mechanism 200 are arranged at intervals in the adhesive tape 400 passing mode, and the first passing roller 220 is located upstream of the glue pressing member 230. It can be easily understood that the free end of the adhesive tape is drawn out from the glue disc 110, wound around the first passing roller 220 and turned at the first passing roller 220, and then extended to the glue pressing member 230 to be fixed by the glue pressing member 230. At this time, the adhesive tape 400 completes the initial assembly, so that the adhesive tape 400 can pass in a subsequent meandering track.

[0069] It should be noted that in the present application, the glue pulling mechanism 300 refers to a component that can pull the free end of the adhesive tape 400 to pull the adhesive tape 400 out of the glue pressing member 230 by a predetermined length. The glue pulling mechanism 300 can be a structure in which a clamping cylinder clamps the adhesive tape 400 of the glue pressing member 230, and when the glue pressing member 230 loosens the adhesive tape 400, a linear drive member drives the clamping cylinder to move along the first direction X, thereby pulling the adhesive tape 400 out of the glue pressing member 230 by a predetermined length. The linear drive member can be a cylinder, a hydraulic cylinder, an electric push rod, etc., or can be in the form of a motor and a transmission assembly.

[0070] In combination with the above description, referring to FIGS. 1, 2 and 3, the glue preparation device of the embodiment of the application performs the following glue preparation action:

[0071] The glue pressing member 230 fixes the free end of the adhesive tape 400, and the drive member 210 drives the first passing roller 220 to move towards the direction of tensioning the adhesive tape 400. Since one end of the adhesive tape 400 is in a fixed state at this time, and the outer periphery of the first passing roller 220 abuts against the adhesive tape 400, the force of the first passing roller 220 tensioning the adhesive tape 400 can be transmitted to the glue disc 110 through the adhesive tape during the process of the drive member 210 driving the first passing roller 220 to move towards the direction of tensioning the adhesive tape 400, so as to rotate the glue disc 110 around itself, thereby pulling the adhesive tape 400 on the glue disc 110.

[0072] When the driving member 210 drives the first passing roller 220 to move from the initial first position to the second position, the adhesive tape 400 on the adhesive disc 110 is pulled out by a preset length. It is easy to understand that the displacement amount of the first passing roller 220 from the first position to the second position is positively correlated with the preset length, that is, the greater the displacement amount of the first passing roller 220 moving towards the direction of tensioning the adhesive tape 400, the greater the preset length of the adhesive tape 400 on the adhesive disc 110 is pulled out, and the preset length corresponds to the length of a single piece of adhesive tape, which is not limited in particular and can be set according to the actual length of the adhesive tape to be attached to the corresponding part of the battery.

[0073] It should be noted that during the process in which the driving member 210 drives the first passing roller 220 to move towards the direction of tensioning the adhesive tape 400 to pull out the adhesive tape 400 on the adhesive disc 110 by a preset length, the tension change of the adhesive tape 400 caused by the movement of the first passing roller 220 can be approximately balanced with the tension change of the adhesive tape 400 caused by the decrease of the winding radius of the adhesive tape 400 on the adhesive disc 110, so that the tension on the adhesive tape 400 is maintained within a stable range, and the probability of wrinkles and tears caused by excessive tension and relaxation of the adhesive tape 400 when being pulled out from the adhesive disc 110 is reduced.

[0074] After the driving member 210 drives the first passing roller 220 to move from the initial first position to the second position to pull out the adhesive tape 400 on the adhesive disc 110 by a preset length, the adhesive pressing member 230 releases the free end of the adhesive tape 400, and at the same time, the adhesive pulling mechanism 300 clamps the free end of the adhesive tape 400 and pulls the adhesive tape 400 to move relative to the adhesive pressing member 230 by a preset length in the first direction X, completing the entire adhesive preparation action, so that the corresponding cutting member can cut the adhesive tape 400 pulled out by a preset length, and the single piece of adhesive tape is discharged.

[0075] It should be noted that during the process in which the adhesive pulling mechanism 300 pulls the adhesive tape 400 relative to the adhesive pressing member 230 by a preset length, the driving member 210 drives the first passing roller 220 to move in the direction opposite to tensioning the adhesive tape 400, so that the first passing roller 220 is reset from the second position to the initial first position. During this process, the displacement amount of the first passing roller 220 from the second position to the first position is positively correlated with the preset length of the adhesive tape 400 pulled relative to the adhesive pressing member 230.

[0076] It can be understood that, since the driving member 210 pulls the adhesive tape 400 out of the preset length on the adhesive disc 110 by driving the first over roller 220 to move in the direction of tensioning the adhesive tape 400, when the tape pulling mechanism 300 pulls the adhesive tape 400 out of the preset length relative to the pressing member 230, the winding radius of the adhesive tape 400 on the adhesive disc 110 only has slight fluctuation, and thus the action of pulling the adhesive tape 400 out of the preset length relative to the pressing member 230 by the tape pulling mechanism 300 does not cause large tension change of the adhesive tape 400. In this way, the tension of the adhesive tape 400 can also be maintained within the stable range, and the probability of wrinkles and tearing caused by relaxation and over-tensioning when the adhesive tape 400 is pulled out of the preset length relative to the pressing member 230 is also reduced.

[0077] Through the above description, it can be easily understood that, by the cooperation of the adhesive storage mechanism 100, the adhesive opening mechanism 200 and the tape pulling mechanism 300, the adhesive device can maintain the tension of the adhesive tape 400 within a stable range during the output of the adhesive tape 400 on the adhesive disc 110, effectively reduce the probability of wrinkles and tearing caused by relaxation and over-tensioning during the pulling of the adhesive tape roll, improve the smoothness and stability of the adhesive tape, and enable the adhesive device to stably complete the adhesive preparation and adhesive supply actions, thereby improving the efficiency of the adhesive tape application to the corresponding parts of the battery and the production efficiency of the battery.

[0078] In some embodiments of the present application, referring to FIGS. 2 and 3, the driving member 210 has a telescopic shaft 211 connected to the first over roller 220, which is extended when the adhesive tape 400 is fixed by the pressing member 230, and is retracted when the tape pulling mechanism 300 pulls the adhesive tape 400.

[0079] In some embodiments, the driving member 210 is configured as a pneumatic cylinder.

[0080] It can be understood that, when the adhesive device is preparing adhesive, the free end of the adhesive tape 400 is fixed by the pressing member 230, the telescopic shaft 211 of the driving member 210 is extended by a preset distance, thereby driving the first over roller 220 to move upward from the initial first position to the second position, so as to pull the adhesive tape 400 on the adhesive disc 110 out of the preset length, complete the adhesive opening action, and reserve the adhesive tape of the preset length in advance.

[0081] The extension of the telescopic shaft 211 of the driving member 210 drives the first over roller 220 to extend, which can dynamically change the tension of the adhesive tape 400 by the first over roller 220, so as to adapt to the tension change of the adhesive tape 400 caused by the decrease of the winding radius of the adhesive tape 400 on the adhesive disc 110, thereby maintaining the tension of the adhesive tape 400 within a stable range during the reservation of the adhesive tape of the preset length, and reducing the probability of wrinkles and tearing caused by relaxation and over-tensioning of the adhesive tape 400.

[0082] Then, the adhesive releasing member 230 releases the free end of the adhesive tape 400, and the adhesive tape releasing mechanism 300 pulls the free end of the adhesive tape 400 out by a preset length in the first direction X. In this process, the extension shaft 211 of the driving member 210 is retracted downward by a preset distance to drive the first over roller 220 to move downward from the second position to reset to the first position, completing the adhesive tape releasing action, so as to pull out the adhesive tape with a preset length of reserve.

[0083] Meanwhile, the extension shaft 211 of the driving member 210 drives the first over roller 220 to reset when the adhesive tape releasing mechanism 300 pulls the adhesive tape 400, so that the first over roller 220 dynamically changes the tension of the adhesive tape 400, and self-adapts to the tension change of the adhesive tape 400 caused by the adhesive tape releasing mechanism 300 pulling the adhesive tape 400, and also does not cause the winding radius of the adhesive tape 400 on the adhesive disc 110 to have a large fluctuation, so as to maintain the tension of the adhesive tape 400 within a stable range during the adhesive tape releasing process, and also reduces the probability of wrinkles and tears of the adhesive tape 400 caused by relaxation and excessive tension.

[0084] It should be noted that the extension shaft 211 of the driving member 210 directly generates a force on the first over roller 220 when it is extended, and indirectly generates a driving force on the adhesive tape 400 through the first over roller 220, so as to increase the tension of the adhesive tape 400. When the driving force of the extension shaft 211 of the driving member 210 on the first over roller 220 and / or the adhesive tape 400 is too large, the adhesive tape is easy to be torn or broken.

[0085] Similarly, since the adhesive tape releasing mechanism 300 continuously generates a pulling force on the adhesive tape 400, and the driving force of the extension shaft 211 of the driving member 210 on the adhesive tape 400 still exists when it is retracted, the adhesive tape 400 needs to overcome the driving force of the extension shaft 211 on the adhesive tape 400 to be stably pulled out by the adhesive tape releasing mechanism 300, and at the same time, the winding radius of the adhesive tape 400 on the adhesive disc 110 does not have a large fluctuation. When the driving force of the extension shaft 211 of the driving member 210 on the adhesive tape 400 is too large, the adhesive tape is also easy to be torn or broken.

[0086] Based on the above problems, in some embodiments, referring to FIGS. 2 and 3, the adhesive releasing mechanism 200 further comprises an adjusting member 240, which is configured to adjust the driving force of the extension shaft 211 on the first over roller 220 and / or the adhesive tape 400 when the extension shaft 211 is extended or retracted.

[0087] In some embodiments, the adjusting member 240 is connected with the driving member 210, and the adjusting member 240 adjusts the driving force of the extension shaft 211 of the driving member 210 on the first over roller 220 and / or the adhesive tape 400, so that the tension change of the adhesive tape 400 caused by the movement of the first over roller 220 in the direction of tensioning the adhesive tape 400 can substantially balance the tension change of the adhesive tape 400 caused by the winding radius of the adhesive tape 400 on the adhesive disc 110 becoming smaller.

[0088] Similarly, by adjusting the driving force of the telescopic shaft 211 of the driving member 210 on the first over roller 220 and / or the adhesive tape 400 through the adjusting member 240, the tension change of the adhesive tape 400 caused by the movement resetting process of the first over roller 220 can be substantially balanced with the tension change of the adhesive tape 400 caused by the movement of the adhesive tape 400 by the pulling mechanism 300.

[0089] In this way, the risk of the adhesive tape 400 being torn or broken due to the driving force of the telescopic shaft 211 of the driving member 210 on the first over roller 220 and / or the adhesive tape 400 being too large can be effectively reduced.

[0090] In some embodiments, referring to FIGS. 2 and 3, the driving member 210 is configured as a pneumatic actuator, the adjusting member 240 is configured as an electrical proportional valve in communication with the driving member 210, and the adjusting member 240 is arranged at the air inlet end of the driving member 210 to adjust the air inlet pressure or the air outlet pressure of the air inlet end.

[0091] In some embodiments, the pneumatic actuator can be a pneumatic cylinder, and the electrical proportional valve is arranged at the air inlet end of the pneumatic cylinder. In some embodiments, the driving member 210 is a low-friction pneumatic cylinder.

[0092] It should be noted that when the telescopic shaft 211 of the driving member 210 is extended, the adjusting member 240 adjusts the air inlet pressure of the air inlet end of the driving member 210 to control the extension amount of the telescopic shaft 211 of the driving member 210, so that the driving force of the telescopic shaft 211 of the driving member 210 on the adhesive tape 400 is within a controllable range, and the risk of the tension of the adhesive tape 400 changing too much and being torn or broken can be reduced.

[0093] When the telescopic shaft 211 of the driving member 210 is retracted, the air inlet end of the driving member 210 serves as an air outlet, and the driving member 210 discharges air outward through the air inlet end. At this time, the adjusting member 240 adjusts the air outlet pressure of the air inlet end of the driving member 210, so that the first over roller 220 can be stably reset, and at the same time, the driving force of the telescopic shaft 211 of the driving member 210 on the adhesive tape 400 can also be within a controllable range, and the risk of the tension of the adhesive tape 400 changing too much and being torn or broken can be reduced.

[0094] It is not difficult to understand that the electrical proportional valve adjusts the air inlet pressure or the air outlet pressure of the air inlet end of the driving member 210 to achieve the effect of adjusting the driving force of the telescopic shaft 211 of the driving member 210 on the adhesive tape 400, and effectively reduce the risk of the tension of the adhesive tape 400 changing too much and being torn or broken.

[0095] In some embodiments, referring to FIG. 2 and FIG. 3, the driving member 210 has a piston cavity (not shown in the figures) in which the telescopic shaft 211 is movably arranged, and the adjusting member 240 is arranged at the air inlet end of the piston cavity. The adjusting member 240 is used to input a first preset air pressure into the piston cavity when the adhesive tape 400 is fixed by the pressing member 230, so as to drive the telescopic shaft 211 to push the first roller 220 to move from the first position to the second position; and the adjusting member 240 is also used to release the pressure of the piston cavity when the adhesive tape 400 is pulled by the pulling mechanism 300.

[0096] In some embodiments, the adhesive tape preparation device further comprises a controller (not shown in the figures), which can be a computer based on PLC logic program control. The driving member 210, the adjusting member 240, the pressing member 230 and the pulling mechanism 300 are all communicatively connected with the controller.

[0097] In some embodiments, the driving member 210 is configured as a cylinder, the adjusting member 240 is an electric proportional valve arranged at the air inlet end of the cylinder, and the electric proportional valve has an air inlet, an air outlet and an air outlet. The pressing member 230 is an opening and closing mechanism, such as a jaw cylinder, and the pulling mechanism 300 is a structure in which the jaw cylinder and the linear driving member are matched.

[0098] When the adhesive tape is opened, the controller controls the pressing member 230 to fix the free end of the adhesive tape 400, controls the air inlet of the electric proportional valve to be communicated with the air inlet end of the driving member 210, and controls the electric proportional valve to input a first preset air pressure into the piston cavity of the driving member 210. The first preset air pressure drives the telescopic shaft 211 to extend, so as to drive the first roller 210 to move from the initial first position to the second position, and the opening of the adhesive tape is completed.

[0099] It should be noted that, under the action of the first preset air pressure, the telescopic shaft 211 can just drive the first roller 210 to move from the initial first position to the second position, and can balance the change of the tension of the adhesive tape 400 caused by the movement of the first roller 220 with the change of the tension of the adhesive tape 400 caused by the decrease of the winding radius of the adhesive tape 400 on the adhesive disc 110. The first preset air pressure can be obtained by debugging the adhesive tape preparation device in advance, and can be set according to actual needs.

[0100] When the adhesive tape is pulled, the controller obtains a signal that the first roller 210 has moved to the second position according to the position feedback of the telescopic shaft 211 on the driving member 210 (i.e. the adhesive tape 400 on the adhesive disc 110 has been pulled out by a preset length), so as to control the pressing member 230 to release the free end of the adhesive tape 400 and control the pulling mechanism 300 to hold the free end of the adhesive tape 400. At the same time, the controller controls the air outlet of the electric proportional valve to be communicated with the air inlet end of the driving member 210 based on the action of the pulling mechanism 300 holding the free end of the adhesive tape 400, and sets the air outlet of the electric proportional valve to be opened when the air pressure value of the piston cavity in the driving member 210 is greater than a second preset air pressure, so as to release the pressure of the piston cavity.

[0101] It should be noted that the second preset air pressure is less than the first preset air pressure, and at this time the electric proportional valve functions as an overflow valve. The second preset air pressure can also be obtained during the debugging of the rubber preparation device in advance, and is set according to actual needs. The second preset air pressure can be 0.

[0102] After the controller completes the setting and control of the electric proportional valve, the rubber pulling mechanism 300 is controlled to pull the rubber belt 400 out of the rubber belt 400 by a preset length along the first direction X. During this process, the telescopic shaft 211 of the driving member 210 is retracted under the action of the rubber belt 400, and at the same time, the gas in the piston cavity is discharged through the electric proportional valve to achieve pressure relief, so as to reduce the reaction force of the telescopic shaft 211 of the driving member 210 on the rubber belt 400 in real time. In this way, the tension change caused by the movement of the first over roller 220 to the rubber belt 400 can be roughly balanced with the tension change caused by the movement of the rubber belt 400 pulled by the rubber pulling mechanism 300, effectively reducing the risk of tearing and breaking of the rubber belt 400 due to excessive tension change.

[0103] The above rubber opening and rubber pulling actions are repeated, so that the rubber belt 400 on the rubber disc 110 is continuously output by a preset length while the tension on the rubber belt 400 is maintained within a stable range, effectively reducing the probability of wrinkling and tearing of the rubber belt due to relaxation and excessive tension during the pulling of the rubber belt, and improving the smoothness and stability of the rubber belt.

[0104] It should be noted that the controller obtains the position feedback of the rubber pulling mechanism 300 to determine that the rubber belt 400 has been pulled out of the rubber belt 400 by a preset length along the first direction X, and the controller controls the rubber pressing member 230 to fix the position of the rubber belt 400 at the rubber pressing member 230 at this time, and controls the cutting member to cut the rubber belt 400 pulled out by a preset length, thereby reducing the risk of loosening of the rubber belt 400 after being cut due to the loss of tension source, and stably completing the discharge of a single rubber sheet.

[0105] Referring to FIGS. 2, 3 and 4, in some embodiments of the present application, the rubber opening mechanism 200 further comprises a sliding rail 250 and a sliding block 260 slidingly installed on the sliding rail 250, and the first over roller 220 is rotatably arranged on the sliding block 260, and the driving end of the driving member 210 is connected to the sliding block 260.

[0106] In some embodiments, the sliding rail 250 is fixed on the rack 500, the first over roller 220 is installed on the sliding block 260 through a rotating shaft or a bearing, and the telescopic shaft 211 of the driving member 210 is connected to the sliding block 260.

[0107] It can be understood that when the telescopic shaft 211 of the driving member 210 is extended or retracted, the slider 260 drives the first passing roller 220 thereon to slide along the slide rail 250 under the action of the telescopic shaft 211 of the driving member 210. In this way, the linearity of the movement of the first passing roller 220 is improved, the risk of deviation of the first passing roller 220 and dislocation of the adhesive tape 400 wound thereon is reduced, and the tension on the adhesive tape 400 is further maintained within a stable range.

[0108] In some embodiments of the present application, referring to FIGS. 1 and 2, the adhesive opening mechanism 200 further comprises a plurality of second passing rollers 270 arranged at intervals, and all the second passing rollers 270 are arranged between the first passing roller 220 and the adhesive pressing member 230. The adhesive tape 400 extends to the adhesive pressing member 230 after being wound around the first passing roller 220 and all the second passing rollers 270 in sequence.

[0109] In some embodiments, the second passing rollers 270 are two, one of which is in a straight line perpendicular to the first direction X with the first passing roller 220, and the other is in a straight line along the first direction X with the adhesive pressing member 230, and the connecting line of the two second passing rollers 270 is inclined relative to the first direction X.

[0110] It can be understood that the adhesive tape 400 on the adhesive disc 110 extends to the adhesive pressing member 230 after being wound around the first passing roller 220 and the two second passing rollers 270 in sequence and is fixed by the adhesive pressing member 230. In this way, the running track of the adhesive tape 400 is turned several times.

[0111] In this way, the stress of the adhesive tape 400 extending from the adhesive disc 110 can be adjusted, and a certain length of the adhesive tape is in excess between the first passing roller 220 and the adhesive pressing member 230. The tension on the adhesive tape 400 during the opening and pulling of the adhesive tape 400 by the adhesive preparation device can be buffered depending on the length of the adhesive tape itself, the tension on the adhesive tape 400 is further maintained within a stable range, the probability of wrinkles and tears caused by relaxation and excessive tension during the pulling of the adhesive tape roll is reduced, and the smoothness and stability of the adhesive tape running are improved.

[0112] In other embodiments, the positions of the adhesive pressing member 230 and all the second passing rollers 270 relative to the first passing roller 220 can be adjusted. On the one hand, the stress of the adhesive tape 400 is conveniently adjusted during the early stage; on the other hand, the running track of the adhesive tape 400 meets the on-site adhesive application requirements.

[0113] In some embodiments of the present application, referring to FIGS. 1 and 2, the adhesive opening mechanism 200 further comprises a third passing roller 280 arranged between the adhesive disc 110 and the first passing roller 220, and the third passing roller 280 has a height difference with the adhesive disc 110 and the first passing roller 220.

[0114] In some embodiments, the adhesive tape 400 extending from the adhesive disc 110 sequentially passes through the third passing roller 280 and turns at the third passing roller 280, passes through the first passing roller 220 and turns at the first passing roller 220, and then extends to the adhesive pressing member 230 after passing through all the second passing rollers 270 and is fixed by the adhesive pressing member 230.

[0115] Since the third passing roller 280 is arranged between the adhesive disc 110 and the first passing roller 220, and there is a height difference between the third passing roller 280 and the adhesive disc 110 and the first passing roller 220, the adhesive tape 400 turns twice when passing through the first passing roller 220, so that the wrap angle of the adhesive tape 400 on the first passing roller 220 is large enough to enable the adhesive disc 110 to rotate around itself by the pulling force of the adhesive tape 400 when the driving member 210 drives the first passing roller 220 to move towards the direction of tensioning the adhesive tape 400, thereby stably pulling out the adhesive tape 400 on the adhesive disc 110 by a preset length and improving the smoothness and stability of the adhesive opening operation.

[0116] Similarly, the position of the third passing roller 280 relative to the first passing roller 220 and / or the adhesive disc 110 can be adjusted, on the one hand, to facilitate the early-stage adjustment of the stress of the adhesive tape 400, and on the other hand, to make the adhesive tape 400 meet the on-site adhesive application requirements.

[0117] In some embodiments of the present application, referring to FIGS. 1 and 5, the adhesive storage mechanism 100 further comprises a detector 120 for detecting the winding radius of the adhesive tape 400 on the adhesive disc 110 and sending an alarm signal when the winding radius of the adhesive tape 400 is less than a preset radius.

[0118] In some embodiments, the detector 120 is configured as an ultrasonic sensor.

[0119] The step of measuring the winding radius of the adhesive tape 400 on the adhesive disc 110 by the ultrasonic sensor can be: installing the ultrasonic sensor at a position perpendicular to the central axis of the adhesive disc 110, so that there is a proper distance between the ultrasonic sensor and the winding surface of the adhesive tape 400 to allow the propagation and reflection of ultrasonic waves, sending an ultrasonic pulse signal to the adhesive disc 110, receiving a return signal generated by the reflection of the ultrasonic waves on the adhesive disc 110 by the sensor, and calculating the winding radius of the adhesive tape 400 on the adhesive disc 110 by measuring the time delay or oscillation period of the return signal and combining the propagation speed of the ultrasonic waves.

[0120] When it is detected that the winding radius of the adhesive tape 400 on the adhesive disc 110 is less than the preset radius, the detector 120 can prompt the user that the adhesive tape 400 is about to run out by sending an alarm signal, so that the user can replace the adhesive tape 400 in time. The alarm signal can be but is not limited to a color signal light, a buzzer emitting a buzzing sound, etc., and the specific implementation is not limited.

[0121] It is understandable that the winding radius of the adhesive tape 400 on the adhesive disc 110 is detected in real time by the detector 120, and an alarm signal is sent when the winding radius of the adhesive tape 400 is less than the preset radius, so that the user can replace the adhesive tape 400 in time, and the continuity of the adhesive tape 400 unloading is improved.

[0122] In some embodiments, referring to FIG. 5, the adhesive storage mechanism 100 further comprises a limiting piece 130 arranged on opposite sides of the adhesive disc 110 in the axial direction and abutting against the corresponding side surface of the adhesive tape roll, for limiting the adhesive tape roll in the axial direction of the adhesive disc 110, reducing the probability of the adhesive tape roll deviating in the axial direction of the adhesive disc 110 during the pulling process, and further improving the stability of the adhesive tape 400 being pulled out.

[0123] In some embodiments, the application also provides a gluing device and a battery production line, wherein the gluing device comprises the adhesive storage device of any of the above embodiments.

[0124] It is understandable that the gluing device and the battery production line of the application have the same technical effects as the adhesive storage device because the gluing device is configured with the adhesive storage device. That is, during the process in which the driving piece 210 in the adhesive opening mechanism 200 drives the first over roller 220 to move towards the direction of tensioning the adhesive tape 400 to pull out the adhesive tape 400 on the adhesive disc 110 by a preset length, the tension change caused by the movement of the first over roller 220 to the adhesive tape 400 can be balanced with the tension change caused by the decrease of the winding radius of the adhesive tape 400 on the adhesive disc 110. During the process in which the adhesive pulling mechanism 300 pulls out the adhesive tape 400 relative to the pressing piece 230 by a preset length, the adhesive pulling mechanism 300 does not cause a large tension change to the adhesive tape 400. In this way, the tension on the adhesive tape 400 can be maintained within a stable range during the output process of the adhesive tape 400 on the adhesive disc 110, effectively reducing the probability of wrinkles and tears caused by relaxation and excessive tension during the pulling process of the adhesive tape roll, improving the smoothness and stability of the adhesive tape, enabling the adhesive storage device to stably complete the adhesive storage and glue supply actions, and further improving the efficiency of gluing the corresponding parts of the battery, thereby improving the production efficiency of the battery.

[0125] Referring to FIGS. 1-5, in some embodiments of the application, an adhesive storage device, a gluing device, and a battery production line are provided.

[0126] The adhesive preparation device comprises a storage mechanism 100, a first adhesive opening mechanism 200, and a second adhesive opening mechanism 300.

[0127] The adhesive preparation device comprises a storage mechanism 100, a first adhesive opening mechanism 200, and a second adhesive opening mechanism 300.

[0128] The adhesive preparation device, the adhesive preparation device, and the battery production line can balance the tension change of the adhesive tape 400 caused by the movement of the first adhesive opening mechanism 200 and the movement of the second adhesive opening mechanism 300, so that the tension of the adhesive tape 400 can be maintained within a stable range during the output of the adhesive tape 400 on the adhesive disc 110, effectively reducing the probability of wrinkles and tears caused by relaxation and excessive tension during the output of the adhesive tape, improving the smoothness and stability of the adhesive tape, and enabling the adhesive preparation device to stably complete the adhesive preparation and supply of the adhesive tape, thereby improving the efficiency of the adhesive tape on the corresponding part of the battery, and improving the production efficiency of the battery.

[0129] The technical features of the above-described embodiments can be combined in any manner, and to simplify the description, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present application.

[0130] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
