[0002] In the current field of battery technology, attaching a glue frame to the solid-state battery stack is one of the solutions to solve the edge insulation of the solid-state battery.

[0003] In the relevant technical scheme, the glue frame is currently bonded to the edge of the battery electrode. Although this process can complete the bonding of the electrode edge and the glue frame, the glue frame structure is usually thin and fine, and the texture is relatively soft. It is easy to deform during the bonding process, which ultimately leads to poor insulation effect of the glue frame. Summary of the invention

[0004] The embodiments of the present application provide a bonding system, a bonding method for a pole piece and a rubber frame body, and a battery production system, which can reduce the deformation of the rubber frame body during the bonding process and retain the insulation properties of the rubber frame body itself.

[0005] In the first aspect, according to an embodiment of the present application, a bonding system is proposed, including a rubber frame release component and a patch assembly, the rubber frame release component including a support, a unwinding component and a rewinding component, the unwinding component is configured to release the rubber frame substrate, the rubber frame substrate including a rubber frame body and a packaging film adhered to the rubber frame body, the rewinding component is arranged downstream of the unwinding component and is configured to peel the packaging film from the rubber frame body and rewind the peeled packaging film, the support component is arranged downstream of the unwinding component, the support component is configured to support the rubber frame body from which the packaging film is at least partially peeled off; the patch assembly is arranged downstream of the unwinding component, the patch assembly is configured to move the electrode to the support component, and bond the electrode to the rubber frame body after the packaging film is peeled off.

[0006] In this embodiment, the unwinding component in the bonding system is used to release the rubber frame substrate, and the rubber frame substrate is placed on the support. The packaging film in the rubber frame substrate is connected to the winding component and the packaging film is rolled up by the rotation of the winding component, so as to gradually peel off the packaging film on the rubber frame substrate until the rubber frame body is exposed on the support. Then, the electrode is moved to the support by the patch assembly in the bonding system and bonded to the exposed rubber frame body, thereby completing the bonding process of the electrode and the rubber frame body. This process can place the rubber frame body statically on the support while moving the electrode and the rubber frame body to complete the bonding, thereby reducing the risk of deformation of the rubber frame body during the bonding process. After the two are bonded, the rubber frame body can form better insulation protection for the electrode, and retain the insulation properties of the rubber frame body to the greatest extent. At the same time, the above system also facilitates the staff to complete the bonding of the electrode and the rubber frame body.

[0007] According to one aspect of the embodiment of the present application, the bonding system also includes a collector and a controller; the collector is configured to obtain the actual position parameters of the plastic frame body to be bonded with the electrode; the controller is configured to control the patch assembly to move the electrode to the support and bond it with the plastic frame body according to the actual position parameters. By setting the collector and the controller in the bonding system, the position of the plastic frame body can be obtained in real time by using the collector, so that the controller can control the patch assembly to drive the electrode to move and complete the bonding according to the actual position of the plastic frame body, thereby improving the bonding accuracy of the bonding process, having higher bonding accuracy, reducing the risk of bonding deviation, and facilitating the precise bonding of the electrode and the plastic frame body, and better exerting the insulation performance of the plastic frame body.

[0008] According to one aspect of the embodiment of the present application, the controller is configured to determine the movement trajectory of the patch assembly according to the actual position parameters, and control the patch assembly to move according to the movement trajectory until the support member and the plastic frame body are in contact. By providing a movement trajectory for the patch assembly, the controller can further control the movement of the patch assembly, complete the mobile patch process of the patch assembly with higher precision, and further improve the accuracy of the overall patch.

[0009] According to one aspect of the embodiment of the present application, the controller is configured to determine the displacement of the rubber frame body to be bonded with the pole piece according to the deviation between the actual position parameter and the preset position parameter corresponding to the predetermined bonding position on the support, and control the rotation of the unwinding component and the winding component to adjust the rubber frame body to be bonded with the pole piece to the predetermined bonding position. By numerically comparing the actual position parameter obtained with the preset position parameter, the data is used to more accurately reflect the position deviation of the rubber frame body, and the controller is used to more accurately drive the unwinding component and the winding component to rotate and adjust, and the position adjustment is completed more specifically, providing guarantee for the subsequent precise bonding of the pole piece.

[0010] According to one aspect of the embodiment of the present application, the packaging film includes a first film layer adhered to the upper surface of the plastic frame body and a second film layer adhered to the lower surface of the plastic frame body, and the winding assembly includes a first reel and a second reel, the first reel is configured to wind up the first film layer, and the second reel is configured to wind up the second film layer and drive the plastic frame body to move relative to the support member along the first direction. By setting the first reel and the second reel to respectively drive the first film layer and the second film layer of the plastic frame substrate to wind up, the upper and lower packaging films of the plastic frame substrate can be wound up at the same time, which better adapts to the winding process of the two packaging films, improves the automation capability of substrate film removal, and has higher film removal efficiency.

[0011] According to one aspect of the embodiment of the present application, the support member includes a first surface and a second surface arranged relatively along a second direction, the first surface is configured to carry the rubber frame body, the second film layer and the pole piece, the first reel is arranged on the side of the first surface away from the second surface, the second reel is arranged on the side of the second surface away from the first surface, and the second direction intersects with the first direction. By arranging the first reel on the side where the first surface is located and the second reel on the side where the second surface is located, the first reel is closer to the first film layer on the upper side and the second reel is closer to the second film layer on the lower side, so that the first reel is easier to connect and roll up with the first film layer, and the second reel is easier to connect and roll up with the second film layer, which improves the convenience of rolling up the packaging film and has a higher rolling efficiency.

[0012] According to one aspect of the embodiment of the present application, the support member has a first end and a second end relative to each other along a first direction, the rubber frame body can move from the first end to the second end, the first scroll is located on the side of the first end away from the second end, and the projection of the support member in the second direction covers the second scroll. By arranging the first scroll on the side close to the first end of the support member, the first scroll can complete the peeling of the first film layer before the rubber frame substrate enters the support member, and the rubber frame body can be more fully exposed on the support member. At the same time, the second scroll is arranged on the lower side of the support member, which is conducive to the separation between the rubber frame body and the second film layer, making it easier to complete the peeling of the second film layer, and overall more conducive to the removal of the packaging film.

By arranging the first guide shaft between the support member and the second reel, the second film layer is connected to the second reel after bypassing the first guide shaft, so that the second film layer at the bottom of the support member is closer to the bottom surface of the support member, and the rubber frame body is more easily separated from the second film layer at the end of the support member, which is more conducive to completing the film removal of the rubber frame body.

[0014] According to one aspect of the embodiment of the present application, the rubber frame release assembly includes a guide member, which is arranged on a side of the support member close to the unwinding assembly, and the guide member and the support member are located in the same horizontal plane, so that the rubber frame substrate released by the unwinding assembly can bypass the guide member and be placed on the support member. By arranging a guide member on the side close to the unwinding assembly, the rubber frame substrate is guided by the guiding function of the guide member, so that the rubber frame substrate can be unwound more smoothly and placed on the support member, ensuring that the rubber frame substrate remains in a horizontal state on the support member, providing a stable basic guarantee for the subsequent bonding of the electrode piece.

[0015] According to one aspect of the embodiment of the present application, the guide member includes a second guide shaft and a third guide shaft that are spaced apart, the second guide shaft and the third guide shaft are located on the same horizontal plane as the support member, and the rubber frame substrate can pass through the gap between the second guide shaft and the third guide shaft and be placed on the support member. By setting the guide member in the structural form of the second guide shaft and the third guide shaft, on the basis of utilizing the gap between the two to provide stable unwinding for the rubber frame substrate, it can also better cooperate with the first reel to complete the winding of the first film layer, provide guidance for the winding of the first film layer, thereby better cooperating with the overall winding and unwinding process.

[0016] According to one aspect of the embodiment of the present application, the bonding system further includes a frame, and the support, the unwinding assembly, and the winding assembly are respectively connected to the frame.

[0048] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0049] For the anode electrode in the power battery, it is necessary to fit a rubber frame on its edge, so as to utilize the insulating properties of the rubber frame to make the anode electrode have an insulated edge, and then stack it with the cathode electrode to complete the preparation process of the anode and cathode in the battery.

[0050] In the related art, the rubber frame is usually directly put on the edge of the pole piece. However, since the rubber frame is made of a rubber insulating material, its texture is relatively soft, and the rubber frame is thin and fine, the rubber frame is easily deformed or even damaged during the process of fitting it to the edge of the pole piece, affecting the insulation performance of the edge of the pole piece.

[0051] Based on the above considerations, in order to solve the problem that the rubber frame is easily deformed during the bonding process of the electrode and the rubber frame, the present application provides a bonding system, a bonding method for the electrode and the rubber frame body, and a battery production system. The bonding system includes a rubber frame release component and a patch assembly. The rubber frame release component includes a support, a reeling component and a reeling component. The reeling component is configured to release the rubber frame substrate, the rubber frame substrate includes a rubber frame body and a packaging film adhered to the rubber frame body. The reeling component is arranged downstream of the unwinding component and is configured to peel the packaging film from the rubber frame body and reel up the peeled packaging film. The support is arranged downstream of the unwinding component, and the support is configured to support the rubber frame body from which the packaging film is at least partially peeled off; the patch assembly is arranged downstream of the unwinding component, and the patch assembly is configured to move the electrode to the support component and bond the electrode to the rubber frame body after the packaging film is peeled off.

[0052] The unwinding component in the bonding system is used to release the rubber frame substrate and place the rubber frame substrate on the support. The packaging film in the rubber frame substrate is connected to the winding component and the packaging film is rolled up by the rotation of the winding component, thereby gradually peeling off the packaging film on the rubber frame substrate until the rubber frame body is exposed on the support. Subsequently, the electrode is moved to the support by the patch assembly in the bonding system and bonded to the exposed rubber frame body, thereby completing the bonding process of the electrode and the rubber frame body. This process enables the rubber frame body to be placed statically on the support while the moving electrode is bonded to the rubber frame body, thereby reducing the risk of deformation of the rubber frame body during the bonding process. After the two are bonded, the rubber frame body can provide better insulation protection for the electrode, thereby retaining the insulation properties of the rubber frame body to the greatest extent. At the same time, the above system also facilitates the staff to complete the bonding of the electrode and the rubber frame body.

[0053] It should be noted that the bonding system provided in this application is not limited to the battery field. The bonding system in this application can also be applied to other different technical fields. This application does not limit the technical field to which the bonding system is located.

[0054] The bonding system described in the embodiments of the present application is not limited to the battery field described above, but for the sake of simplicity, the following embodiments are described using power batteries as examples.

[0055] See also Figures 1 to 4 According to an embodiment of the present application, a bonding system is proposed, including a rubber frame releasing component 10 and a patch assembly, the rubber frame releasing component 10 includes a support 11, a unwinding component 12 and a rewinding component 13, the unwinding component 12 is configured to release a rubber frame substrate 30, the rubber frame substrate 30 includes a rubber frame body 32 and a packaging film 31 bonded to the rubber frame body 32, the rewinding component 13 is arranged downstream of the unwinding component 12 and is configured to peel the packaging film 31 from the rubber frame body 32 and rewind the peeled packaging film 31, the support 11 is arranged downstream of the unwinding component 12, the support 11 is configured to support the rubber frame body 32 from which the packaging film 31 is at least partially peeled; the patch assembly is arranged downstream of the unwinding component 12, the patch assembly is configured to move the electrode to the support 11, and bond the electrode to the rubber frame body 32 after the packaging film 31 is peeled.

[0056] Typically, during the bonding process between the rubber frame body 32 and the electrode, the incoming material is often the rubber frame substrate 30 , that is, the rubber frame body 32 is packaged using a packaging film 31 . Optionally, the packaging film 31 may be made of a base paper material, thereby packaging and protecting the rubber frame body 32 .

[0057] In the present embodiment, the incoming rubber frame substrate 30 is wound in the unwinding assembly 12, and the rubber frame substrate 30 is released by the rotation of the unwinding assembly 12, wherein the support member 11 in the rubber frame release assembly 10 can support the released rubber frame substrate 30, and optionally, the support member 11 can be a plate-like structure.

[0058] At the same time, the winding component 13 in the rubber frame releasing component 10 is connected to the packaging film 31 in the rubber frame substrate 30. This is because before the rubber frame body 32 is bonded, the covering packaging film 31 needs to be removed. The rotation of the winding component 13 can drive the packaging film 31 connected thereto to be rolled up, thereby realizing the peeling of the packaging film 31, so that the rubber frame body 32 is exposed on the support member 11.

[0059] Subsequently, when the winding component 13 gradually peels off the packaging film 31, the patch assembly can be used to adsorb the electrode and drive the electrode to fit with the rubber frame body 32 exposed on the support member 11 to complete the final fitting process. Optionally, the patch assembly can be a robotic arm structure and the electrode can be an anode electrode.

[0060] In the above-mentioned bonding process, since the rubber frame body 32 is always located on the support member 11, when the electrode is bonded to the rubber frame body 32 using the patch assembly, the support member 11 can provide support for the bonding process. The rubber frame body 32 always remains stationary compared to the support member 11, and therefore will not be deformed due to the movement of the rubber frame body 32. Bonding the electrode to the stationary rubber frame body 32 reduces the risk of deformation of the rubber frame body 32, thereby providing better structural protection for the rubber frame body 32.

[0061] The embodiment of the present application provides a bonding system, which releases the plastic frame substrate 30 by using the unwinding component 12 in the bonding system, places the plastic frame substrate 30 on the support 11, connects the packaging film 31 in the plastic frame substrate 30 with the winding component 13 and winds the packaging film 31 by rotating the winding component 13, thereby gradually peeling off the packaging film 31 on the plastic frame substrate 30 until the plastic frame body 32 is exposed on the support 11, and then moves the electrode to the support 11 through the patch assembly in the bonding system and bonds it. On the exposed rubber frame body 32, the bonding process of the pole piece and the rubber frame body 32 is completed. This process enables the rubber frame body 32 to be placed statically on the support 11 while the pole piece and the rubber frame body 32 are moved to complete the bonding, thereby reducing the risk of deformation of the rubber frame body 32 during the bonding process. After the two are bonded, the rubber frame body 32 can provide better insulation protection for the pole piece, retaining the insulation properties of the rubber frame body 32 to the greatest extent. At the same time, the above system also facilitates the staff to complete the bonding of the pole piece and the rubber frame body 32.

[0062] As an optional embodiment, the bonding system also includes a collector 40 and a controller; the collector 40 is configured to obtain actual position parameters of the plastic frame body 32 to be bonded with the electrode; the controller is configured to control the patch assembly to move the electrode to the support 11 and bond it with the plastic frame body 32 according to the actual position parameters.

[0063] Optionally, the collector 40 can be a frame positioning camera, which illuminates the frame body 32 on the support 11 through the emitted light, thereby obtaining the actual position parameters of the frame body 32 on the support 11, so as to position the frame body 32 and improve the fitting accuracy with the electrode.

[0064] Specifically, a signal transmission can be formed between the collector 40 and the controller, and the collector 40 transmits the acquired actual position parameters to the controller. The controller can control the movement of the patch assembly according to the actual position parameters, so that the patch assembly drives the electrode to move to the corresponding position of the frame body 32 for bonding.

[0065] The embodiment of the present application provides a bonding system, by setting a collector 40 and a controller in the bonding system, the collector 40 can be used to obtain the position of the frame body 32 in real time, so that the controller controls the patch assembly according to the actual position of the frame body 32 to drive the electrode to move and complete the bonding, thereby improving the bonding accuracy of the bonding process, having higher bonding accuracy, reducing the risk of bonding deviation, and facilitating the precise bonding between the electrode and the frame body 32, thereby better exerting the insulation performance of the frame body 32.

[0066] As an optional embodiment, the controller is configured to determine the moving trajectory of the patch assembly according to the actual position parameters, and control the patch assembly to move according to the moving trajectory until the support member 11 is in contact with the frame body 32 .

[0067] Considering that multiple rubber frame bodies 32 may be arranged on the support member 11 at the same time, when the collector 40 is used to obtain the actual position parameters of one of the rubber frame bodies 32, the information corresponds to the controller controlling the patch assembly to move according to the moving trajectory of the corresponding position to achieve the fitting of the electrode and the rubber frame body 32.

[0068] When the collector 40 obtains the actual position parameters of the next plastic frame body 32, the controller can control the patch assembly to drive the electrode to fit with the plastic frame body 32 at the corresponding position according to another moving trajectory. It can be understood that the plastic frame body 32 at different positions determines the different moving trajectories of the patch assembly.

[0069] An embodiment of the present application provides a bonding system, which provides a moving trajectory for the patch assembly, so that the controller can further control the movement of the patch assembly, complete the moving patch process of the patch assembly with higher precision, and further improve the accuracy of the overall patch.

[0070] As an optional embodiment, the controller is configured to determine the displacement of the rubber frame body 32 to be bonded with the pole piece based on the deviation between the actual position parameter and the preset position parameter corresponding to the predetermined bonding position on the support member 11, and control the rotation of the unwinding assembly 12 and the winding assembly 13 to adjust the rubber frame body 32 to be bonded with the pole piece to the predetermined bonding position.

[0071] Optionally, the controller in this embodiment can also compare the actual position parameters of the obtained rubber frame body 32 with the preset position parameters, thereby controlling the rotation of the unwinding assembly 12 and the winding assembly 13. This is because the unwinding assembly 12 and the winding assembly 13 can determine the movement of the rubber frame body 32 on the support member 11, and then control the rubber frame body 32 to move to the preset position to complete the bonding with the electrode.

[0072] When the rubber frame body 32 is not in the preset position, the controller controls the unwinding assembly 12 and the winding assembly 13 to control the rotation of the two so that the rubber frame body 32 is in the preset position to form a precise fit with the electrode.

[0073] The embodiment of the present application provides a bonding system, which performs numerical comparison between the actual position parameters obtained and the preset position parameters, and more accurately reflects the position deviation of the frame body 32 by using the data. The unwinding assembly 12 and the winding assembly 13 are driven to rotate and adjust more accurately by using the controller, and the position adjustment is completed in a more targeted manner, thereby providing guarantee for the precise bonding of the subsequent electrode.

[0074] As an alternative embodiment, see Figures 1 to 4 The packaging film 31 includes a first film layer 31a adhered to the upper surface of the frame body 32 and a second film layer 31b adhered to the lower surface of the frame body 32. The winding assembly 13 includes a first reel 13a and a second reel 13b. The first reel 13a is configured to wind up the first film layer 31a, and the second reel 13b is configured to wind up the second film layer 31b and drive the frame body 32 to move relative to the support member 11 along the first direction X.

[0075] Optionally, the packaging film 31 in this embodiment can be a two-layer film structure, that is, a first film layer 31a on the upper surface of the packaging frame body 32 and a second film layer 31b on the lower surface of the packaging frame body 32, so that the winding component 13 in this embodiment needs to remove the two film layers separately.

[0076] Therefore, the first film layer 31a and the second film layer 31b are specifically rolled up by the first reel 13a and the second reel 13b in the rolling assembly 13. After the first reel 13a rolls up the first film layer 31a, the rubber frame body 32 is exposed on the support member 11. After the bonding with the electrode is completed, the second reel 13b is used to roll up the second film layer 31b, and finally the rubber frame body 32 is obtained after the packaging film 31 is removed.

[0077] When the second reel 13b is winding the second film layer 31b, it can drive the rubber frame body 32 to move along the first direction X on the support 11 until the second film layer 31b is separated from the rubber frame body 32, and the rubber frame body 32 is also separated from the support 11. At this time, the next rubber frame body 32 on the rubber frame substrate 30 is located on the support 11 to be bonded with the electrode.

[0078] The embodiment of the present application provides a bonding system, which realizes the simultaneous winding of the upper and lower packaging films 31 of the plastic frame substrate 30 by setting a first reel 13a and a second reel 13b to respectively drive the first film layer 31a and the second film layer 31b of the plastic frame substrate 30, thereby better adapting to the winding process of the two packaging films 31, improving the automation capability of substrate film removal, and having higher film removal efficiency.

[0079] As an alternative embodiment, see Figure 1 The support member 11 includes a first surface 11a and a second surface 11b arranged opposite to each other along a second direction Z, the first surface 11a is configured to carry the rubber frame body 32, the second film layer 31b and the pole piece, the first reel 13a is arranged on the side of the first surface 11a away from the second surface 11b, and the second reel 13b is arranged on the side of the second surface 11b away from the first surface 11a, and the second direction Z intersects with the first direction X.

[0080] Optionally, the first surface 11a in this embodiment is the upper surface of the support member 11, and the second surface 11b is the lower surface of the support member 11. The first reel 13a can be arranged on the upper side of the first surface 11a, so that it is convenient to wrap and connect with the first film layer 31a in the frame substrate 30, and the second reel 13b can be arranged on the lower side of the second surface 11b, so that it is convenient to wrap and connect with the second film layer 31b in the frame substrate 30.

[0081] When the packaging film 31 is rolled up by the rolling assembly 13, the first reel 13a rolls up the first film layer 31a before the frame substrate 30 enters the support member 11. After the subsequent bonding with the electrode is completed, the second film layer 31b is wound from the first surface 11a to the second surface 11b and connected with the second reel 13b. When the second reel 13b is rolled up, it can not only roll up the second film layer 31b, but also drive the frame body 32 to move along the first direction X until it is separated from the support member 11.

[0082] The embodiment of the present application provides a bonding system, which arranges the first reel 13a on the side where the first surface 11a is located and the second reel 13b on the side where the second surface 11b is located, so that the first reel 13a is closer to the first film layer 31a on the upper side and the second reel 13b is closer to the second film layer 31b on the lower side, so that the first reel 13a is easier to connect with and roll up the first film layer 31a, and the second reel 13b is easier to connect with and roll up the second film layer 31b, thereby improving the convenience of rolling up the packaging film 31 and having a higher rolling efficiency.

[0083] As an alternative embodiment, see Figure 1 The support member 11 has a first end 11c and a second end 11d opposite to each other along the first direction X. The frame body 32 can move from the first end 11c to the second end 11d. The first scroll 13a is located on the side of the first end 11c away from the second end 11d. The projection of the support member 11 in the second direction Z covers the second scroll 13b.

[0084] Optionally, the first reel 13a for rolling up the first film layer 31a is arranged on a side close to the first end 11c of the support member 11, that is, the side where the rubber frame body 32 is located before entering the support member 11, so that the first film layer 31a can be directly removed so that it can be subsequently bonded to the exposed rubber frame body 32 on the support member 11.

[0085] In this embodiment, the second reel 13b is located directly below the support member 11, so that after the second film layer 31b needs to be folded on the upper surface of the support member 11, it is wrapped around its lower surface and connected with the second reel 13b, so that at the second end 11d of the support member 11, the rubber frame body 32 and the second film layer 31b can be better separated by the moving inertia, reducing the possibility of continuous adhesion between the two.

[0086] The embodiment of the present application provides a bonding system, which arranges the first reel 13a on a side close to the first end 11c of the support member 11, so that the first reel 13a can complete the peeling of the first film layer 31a before the frame substrate 30 enters the support member 11, and the frame body 32 can be more fully exposed on the support member 11. At the same time, the second reel 13b is arranged on the lower side of the support member 11, which is conducive to the separation between the frame body 32 and the second film layer 31b, and it is easier to complete the peeling of the second film layer 31b, which is more conducive to the removal of the packaging film 31 as a whole.

[0087] As an optional embodiment, the frame release assembly 10 further includes a first guide shaft 1, the first guide shaft 1 is located between the support member 11 and the second reel 13b, and the second film layer 31b can bypass the first guide shaft 1 and then connect to the second reel 13b.

[0088] Optionally, the first guide shaft 1 is arranged between the support member 11 and the second scroll 13b, so that it can be closer to the support member 11, so that the second film layer 31b first bypasses the first guide shaft 1 after being folded from the upper surface of the support member 11 to the lower surface, so that the second film layer 31b is closer to the lower surface of the support member 11 and tends to be flatter, which is more conducive to separating the second film layer 31b from the rubber frame body 32 by inertia, and further reducing the risk of the two sticking together at the second end 11d.

[0089] The embodiment of the present application provides a bonding system, which disposes a first guide shaft 1 between the support member 11 and the second reel 13b, so that the second film layer 31b is connected to the second reel 13b after bypassing the first guide shaft 1, so that the second film layer 31b is closer to the bottom surface of the support member 11 at the bottom of the support member 11, and it is easier to separate the rubber frame body 32 from the second film layer 31b at the end of the support member 11, which is more conducive to completing the film removal of the rubber frame body 32.

[0090] As an optional embodiment, the rubber frame release component 10 includes a guide member 50, which is arranged on a side of the support member 11 close to the unwinding component 12. The guide member 50 and the support member 11 are located in the same horizontal plane. The rubber frame substrate 30 released by the unwinding component 12 can bypass the guide member 50 and be placed on the support member 11.

[0091] Optionally, the guide member 50 in this embodiment can be a guide shaft structure, which is arranged on the side of the support member 11 close to the unwinding component 12, so that in the process of the unwinding component 12 gradually releasing the rubber frame substrate 30, it can be guided by bypassing the guide member 50, so that the rubber frame substrate 30 moves along the side where the support member 11 is located.

[0092] Optionally, the guide member 50 and the support member 11 are arranged at the same horizontal plane, so that when the frame substrate 30 passes through the guide member 50 , its moving direction is changed and it is at the same horizontal plane as the support member 11 , providing guidance for the frame substrate 30 to be placed smoothly on the support member 11 .

[0093] The embodiment of the present application provides a bonding system, which provides a guide member 50 on a side close to the unwinding component 12, and utilizes the guiding effect of the guide member 50 to guide the rubber frame substrate 30, so that the rubber frame substrate 30 can be unwound more smoothly and placed on the support member 11, ensuring that the rubber frame substrate 30 maintains a horizontal state on the support member 11, providing a stable basic guarantee for the subsequent bonding of the electrode.

[0094] As an optional embodiment, the guide member 50 includes a second guide shaft 2 and a third guide shaft 3 that are spaced apart, the second guide shaft 2 and the third guide shaft 3 are located in the same horizontal plane as the support member 11, and the rubber frame substrate 30 can pass through the gap between the second guide shaft 2 and the third guide shaft 3 and be placed on the support member 11.

[0095] In this embodiment, the guide member 50 is set to a structural form in which the second guide shaft 2 and the third guide shaft 3 are spaced apart. At this time, the unwinding component 12 passes the released frame substrate 30 through the gap between the two shafts, thereby providing horizontal guidance for the frame substrate 30 with the help of the third guide shaft 3, so that it remains flat on the support member 11. At the same time, the first film layer 31a can be peeled off with the help of the second guide shaft 2, and the first film layer 31a can be guided to the first reel 13a for winding.

[0096] The embodiment of the present application provides a bonding system, which, by setting the guide member 50 as a second guide shaft 2 and a third guide shaft 3, can better cooperate with the first reel 13a to complete the winding of the first film layer 31a on the basis of utilizing the gap between the two to provide stable unwinding for the rubber frame substrate 30, and provide guidance for the winding of the first film layer 31a, thereby better cooperating with the overall winding and unwinding process.

[0097] As an optional embodiment, the laminating system further includes a frame 60, and the support member 11, the unwinding assembly 12 and the rewinding assembly 13 are respectively connected to the frame 60.

[0098] Optionally, the frame 60 may be a plate-like structure, which functions to provide support for the entire rubber frame release assembly 10. The support member 11, the unwinding assembly 12 and the winding assembly 13 may be connected to the frame 60 respectively to form a relatively stable overall structure.

[0099] The embodiment of the present application provides a bonding system, which provides a stable structural load for the frame release assembly 10 by setting a frame 60 in the bonding system, improves the stability of the entire structure, and provides a reliable load-bearing basis for the subsequent electrode bonding process.

[0107] After completing the above preparation work, the process proceeds to step S3, where the winding assembly 13 is driven to start rotating and winding, so that the packaging film 31 is gradually wound and peeled off from the substrate. At this time, the plastic frame body 32 is gradually exposed on the support member 11, and the removal of the packaging film 31 is completed.

[0108] Finally, in step S4, the patch assembly is used to absorb the electrode to complete the bonding of the exposed frame body 32. This process ensures the relative stillness of the frame body 32 on the support 11.
