Description

Technical Field

[0001] The present application relates to the technical field of battery processing, and in particular to a gluing device, a battery cell gluing apparatus, and a battery cell gluing method. Background Art

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the sustainable development of the automotive industry. For electric vehicles, battery technology is a key factor in their development.

[0003] Batteries typically consist of multiple cells. During the battery production process, glue is applied to the surface of each cell to allow it to adhere to other components. In the prior art, this process involves workers applying glue to the cells, which is slow and affects battery production efficiency. Summary of the Invention

[0004] The present application aims to solve at least one of the technical problems in the background art. To this end, one object of the present application is to provide a gluing device, a battery cell gluing apparatus, and a battery cell gluing method to improve the gluing efficiency of battery cells.

[0005] An embodiment of the first aspect of the present application provides a gluing device, which includes: a base, configured to place the workpiece to be glued; a positioning mechanism, configured to fix the workpiece to be glued at a first preset position of the base; a gluing mechanism, including a placement platform and a gluing component, the placement platform is configured to place glue, the glue component is configured to absorb glue, and move from the placement platform to the first preset position to attach the glue to the workpiece to be glued.

[0006] In the technical solution of the embodiment of the present application, the gluing device can fix the workpiece to be glued using a positioning mechanism. Then, the gluing assembly attaches the glue placed on the placement platform to the workpiece to be glued on the base, thereby achieving automatic gluing of the workpiece to be glued. The gluing speed is fast and the gluing efficiency is high, thereby improving battery production efficiency. At the same time, automatic gluing reduces manual operations and saves labor costs.

[0007] In some embodiments, the base includes: a bracket; a conveying platform located on the bracket and configured to place the adhesive-applied component; and a power assembly connected to the bracket, configured to drive the conveying platform to move the adhesive-applied component to a first preset position. The power assembly drives the conveying platform to move the adhesive-applied component to the first preset position. After the adhesive-applied component reaches the first preset position, the power assembly is controlled to stop, allowing the adhesive-applied component to move to the first preset position. This provides more convenient control over the movement of the adhesive-applied component.

[0008] In some embodiments, the side of the surface of the support with the conveying platform has an anti-falling bar. The provision of the anti-falling bar can reduce the risk of the adhesive-bonded piece falling and improve the safety of the adhesive-bonded piece during the adhesive bonding process.

[0009] In some embodiments, the positioning mechanism is configured to block movement of the adhesive-applied member and secure it at a first predetermined position. The positioning mechanism blocks movement of the adhesive-applied member, so that even after the adhesive-applied member moves to the first predetermined position, the power assembly continues to operate, and the positioning mechanism secures the adhesive-applied member at the first predetermined position, thereby achieving positioning of the adhesive-applied member.

[0010] In some embodiments, the movement direction of the adhesive-applied member is a first direction, and the positioning mechanism includes: a first drive assembly connected to the bracket; and a first stopper connected to the first drive assembly; wherein the first drive assembly is configured to drive the first stopper to move so that at least a portion of the first stopper is located at a second preset position to block the adhesive-applied member, thereby positioning the adhesive-applied member at the first preset position, with the first preset position and the second preset position being adjacent to each other along the first direction. During the adhesive-applied process, the first drive assembly drives the first stopper to move to the second preset position. When the adhesive-applied member moves to the first preset position adjacent to the second preset position, the first stopper can block the movement of the adhesive-applied member, thereby preventing the adhesive-applied member from continuing to move due to inertia, thereby affecting the accuracy of the positioning mechanism in positioning the adhesive-applied member.

[0011] In some embodiments, one of the side of the glue assembly facing the first stopper and the side of the first stopper facing the glue assembly has a positioning hole, and the other of the side of the glue assembly facing the first stopper and the side of the first stopper facing the glue assembly has a positioning pin. During the process of gluing the glue assembly to the part to be glued, the positioning pin is located in the positioning hole. The positioning pin and the positioning hole are provided, and the positioning pin is located in the positioning hole during gluing. During each gluing process, the relative position of the glue assembly and the first stopper remains unchanged. Since the relative position of the first stopper and the part to be glued is constant, the relative position of the glue assembly and the part to be glued remains unchanged. For battery cells of the same model, the shapes of the battery cells are the same, so the glue assembly can glue the same position of the battery cells during the gluing process, which increases the accuracy of gluing the battery cells and provides a better gluing effect.

[0012] In some embodiments, the first stopper includes: a first stopper connected to the first drive assembly; a second stopper connected to the first stopper, and the first stopper and the second stopper intersect, and when the part to be glued is located at the first preset position, the first stopper and the second stopper respectively fit with two adjacent side edges of the part to be glued. The first stopper includes the first stopper and the second stopper, and the first stopper and the second stopper respectively fit with two adjacent side edges of the part to be glued, so that the contact area between the first stopper and the part to be glued is larger, and the positioning mechanism has a better positioning effect on the part to be glued. At the same time, when the part to be glued moves toward the first stopper, the first stopper can block the movement of the part to be glued, or when the part to be glued moves toward the second stopper, the second stopper can block the movement of the part to be glued, so that the part to be glued can be better fixed and the subsequent gluing effect can be improved.

[0013] In some embodiments, the positioning mechanism further comprises: a second drive assembly connected to the bracket, the second drive assembly and the first drive assembly being located on opposite sides of the bracket arranged along a second direction, the second direction intersecting the first direction; and a second stopper connected to the second drive assembly; wherein the second drive assembly is configured to drive the second stopper to move so that when the part to be glued is located in the first preset position, the part to be glued is located between the first stopper and the second stopper. When the part to be glued is located in the first preset position, the part to be glued is located between the first stopper and the second stopper, so that both opposite sides of the part to be glued are blocked, thereby improving the positioning effect of the part to be glued, reducing the possibility of movement of the part to be glued, and improving the subsequent gluing effect.

[0014] In some embodiments, the second stopper includes a third stopper connected to the second drive assembly; and a fourth stopper connected to the third stopper, with the third and fourth stopper intersecting. When the adhesive-applied component is in the first predetermined position, the third and fourth stopper respectively engage two adjacent side edges of the adhesive-applied component, with the third stopper opposing the first stopper and the fourth stopper opposing the second stopper. The first, second, third, and fourth stopper form a frame-like structure, with the battery cell positioned within the frame. This restricts the movement of the battery cell in four directions, thereby better securing the adhesive-applied component and improving subsequent adhesive application.

[0015] In some embodiments, the adhesive laminating device further comprises: a distance sensor located on the bracket, the distance sensor being configured to detect the distance between the distance sensor and the workpiece to be adhesively applied; and a controller communicatively connected to both the distance sensor and the power assembly. The distance sensor is further configured to transmit the distance between the distance sensor and the workpiece to be adhesively applied to the controller, and the controller is configured to control the power assembly to stop operating if the distance between the distance sensor and the workpiece to be adhesively applied is less than or equal to a preset distance value. The controller controls the operation of the power assembly based on the distance between the distance sensor and the workpiece to be adhesively applied, thereby achieving automated control of the position of the workpiece to be adhesively applied, reducing labor costs, and making the adhesive laminating device more automated.

[0016] In some embodiments, the placement platform includes: a support plate having a first end and a second end relative to each other; wherein the adhesive includes a plurality of adhesive strips arranged side by side, the arrangement direction of the plurality of adhesive strips being the same as the arrangement direction of the first end and the second end, the plurality of adhesive strips being located between the first end and the second end, and the adhesive strips closer to the second end of the plurality of adhesive strips being equidistant from the second end. Placing the adhesive strips on the support plate provides space for placement of the adhesive strips, and at the same time, the adhesive strips closer to the second end of the plurality of adhesive strips are equidistant from the second end, i.e., multiple adhesive applications are performed, and the relative positions of the adhesive strips closer to the second end of the plurality of adhesive strips are constant. The adhesive application component can always adhere to the adhesive strips at the second end during the process of adsorbing the adhesive strips, so that the trajectory of each movement of the adhesive application component is the same, making it easier to control the movement of the adhesive application component.

[0017] In some embodiments, the placement platform further comprises: a stop bar located on the same side of the support plate as the adhesive strip, the stop bar being proximal to the second end, a plurality of adhesive strips being located between the first end and the stop bar, and adhesive strips proximal to the stop bar abutting against the stop bar; a first elastic element located on a side of the support plate facing away from the stop bar and connected to the support plate; wherein the adhesive further comprises release paper, the plurality of adhesive strips being located on the release paper, a portion of the release paper having the adhesive strips being in contact with the surface of the support plate, and another portion of the release paper extending through the second end and connected to the first elastic element. After the adhesive strips are attached to the adhesive strips by the adhesive application assembly, a gap exists between the adhesive strips and the stop bar, such that the stop bar cannot restrict their movement. Under the elastic force of the first elastic element, the release paper moves toward the second end, and the adhesive strips on the release paper follow the movement of the release paper, causing the adhesive strips proximal to the stop bar to abut against the stop bar. The distance between the stop bar and the second end is constant, thereby maintaining a constant distance between the adhesive strips proximal to the second end. This eliminates the need for manual control of the adhesive strip movement, reduces labor costs, and achieves automated adhesive application.

[0018] In some embodiments, the first elastic element is connected to the support plate via a first adjusting bolt, and the first adjusting bolt is used to adjust the distance between the first elastic element and the second end. The first elastic element pulls the release paper to move by elastic force. As the number of adhesive applications increases, the release paper moves toward the first elastic element, and the first elastic element gradually recovers its deformation. When the first elastic element returns to a non-elastic state, the first elastic element can no longer provide elastic force to pull the release paper to move. At this time, the distance between the first elastic element and the second end can be adjusted by screwing the first adjusting bolt, so that the distance between the first elastic element and the second end increases. The release paper will pull the first elastic element, and the first elastic element can regenerate elastic force, so that the first elastic element can pull the release paper to move by elastic force.

[0019] In some embodiments, the placement platform further includes a second elastic element located on the same side of the support plate as the rubber strip, the second elastic element being connected to the support plate and abutting against an end of the rubber strip away from the second end. The second elastic element exerts a spring force that pushes the rubber strip toward the second end, thereby ensuring that the rubber strips closest to the second end of the plurality of rubber strips are always at an equal distance from the second end.

[0020] In some embodiments, the second elastic element is movably connected to the support plate via a second adjusting bolt, and the second adjusting bolt is used to adjust the distance between the second elastic element and the second end. The second elastic element pulls the release paper through elastic force. As the number of adhesive applications increases, the release paper moves toward the first elastic element. The second elastic element pushes the adhesive strip through elastic force. As the number of adhesive applications increases, the adhesive strip moves toward the second end, and the second elastic element gradually recovers its deformation. When the second elastic element returns to a state without elastic force, the second elastic element may not be able to push the adhesive strip to move. At this time, the distance between the second elastic element and the second end can be adjusted by screwing the second adjusting bolt, thereby increasing the deformation of the second elastic element and the elastic force provided by the second elastic element, so that the second elastic element can push the adhesive strip to move.

[0021] In some embodiments, the placement platform further includes: limit strips located on the support plate, the limit strips being located on opposite sides of the adhesive strip along its length. The limit strips can limit movement of the adhesive strip along its extension direction, thereby reducing movement of the adhesive strip and improving the effect of subsequent adhesive application.

[0022] In some embodiments, the gluing assembly includes: a sliding element including a first slide rail and a second slide rail, the second slide rail being connectable to the first slide rail and movable along the track of the first slide rail, the track of the first slide rail being parallel to the arrangement direction of the placement platform and the first preset position, and the track of the second slide rail being perpendicular to the surface of the part to be glued; and a gluing element connected to the second slide rail and movable along the track of the second slide rail. The provision of the first and second slide rails allows the gluing element to move in at least two directions, allowing the gluing element to absorb glue from the placement platform, transport the glue from the placement platform to the first preset position, and adhere the glue to the battery cell.

[0023] In some embodiments, the gluing element includes: a connector connected to the second slide rail; a gluing plate located on the side of the connector facing the part to be glued; a connecting rod, the ends of which are respectively connected to the connector and the gluing plate; a buffer spring sleeved on the connecting rod, the ends of the buffer spring respectively abutting against the gluing plate and the connector. When the gluing plate is gluing the battery cell, the gluing plate moves along a third direction and applies pressure to the battery cell so that the glue is attached to the battery cell. The buffer spring can form a buffer when the gluing plate applies pressure to the battery cell, thereby reducing the pressure applied by the gluing plate on the battery cell. This prevents damage to the battery cell caused by excessive pressure.

[0024] In some embodiments, the gluing device further includes an image capture mechanism configured to capture an image of the workpiece after gluing. The image capture mechanism captures the image of the workpiece after gluing, and the gluing quality can be determined based on the image, allowing staff to understand the gluing quality in real time without affecting the gluing process to a certain extent.

[0025] An embodiment of the second aspect of the present application provides a battery cell gluing device, the gluing device comprising any one of the gluing devices of the above embodiments, the gluing device being used to gluing the battery cell.

[0026] In some embodiments, the battery cell comprises a prismatic battery cell, and the gluing device comprises two gluing mechanisms; one of the two gluing mechanisms is used to apply glue to two opposing sides of the prismatic battery cell, and the other of the two gluing mechanisms is used to apply glue to two other opposing sides of the prismatic battery cell. The large surface of the prismatic battery cell has four sides, and two opposing sides of the four sides extend in the same direction. By providing two gluing mechanisms, one of the gluing mechanisms can be used to apply glue to two opposing sides of the prismatic battery cell, while the other gluing mechanism can be used to apply glue to the other two opposing sides of the prismatic battery cell, thereby achieving gluing of all four sides of the large surface of the prismatic battery cell.

[0027] An embodiment of the third aspect of the present application provides a method for gluing a battery cell, the method comprising: using a positioning mechanism to fix the battery cell to a first preset position of a base; controlling the gluing component to absorb glue from a placement platform, and moving from the placement platform to the first preset position to attach the glue to the battery cell.

[0028] In some embodiments, a positioning mechanism is used to fix the battery cell at a first preset position of the base, including: placing the battery cell on a conveying platform; controlling a power assembly to drive the conveying platform to move the battery cell to the first preset position.

[0029] In some embodiments, controlling the power assembly to drive the conveying platform to move so that the battery cell moves to a first preset position includes: detecting the distance between the distance sensor and the battery cell through a distance sensor, and transmitting the distance between the distance sensor and the battery cell to a controller; in response to the distance between the distance sensor and the battery cell being less than or equal to a preset distance value, the controller controls the power assembly to stop working.

[0030] In some embodiments, a positioning mechanism is used to fix the battery cell at a first preset position of the base, and also includes: controlling the first drive component to drive the first block to move so that at least a portion of the first block is located at a second preset position to block the battery cell, so that the battery cell is located at the first preset position, and the first preset position and the second preset position are adjacent along the moving direction of the battery cell.

[0031] In some embodiments, when the battery cell is located at the first preset position, a positioning mechanism is used to fix the battery cell to the first preset position of the base, and the method further includes: controlling the second drive assembly to drive the second block to move so that the battery cell is located between the first block and the second block.

[0032] In some embodiments, the glue component is controlled to absorb glue from the placement platform and move from the placement platform to a first preset position to attach the glue to the battery cell, including: controlling the second slide rail to move along the track of the first slide rail, so that the glue component moves to the placement platform to absorb glue; controlling the second slide rail to move along the track of the first slide rail, so that the glue component moves to the battery cell; controlling the glue component to move along the track of the second slide rail, so that the glue component moves toward the battery cell to attach the glue to the battery cell.

As power battery applications continue to expand, market demand is also growing.

[0063] Batteries consist of multiple cells, each of which is covered with adhesive to facilitate connection with other components and ensure battery integrity. Traditionally, double-sided tape has been applied to the surfaces of the cells, but this method is inefficient and can hinder battery production.

[0064] An embodiment of the present application provides a gluing device, which includes a base, a positioning mechanism, and a gluing mechanism. The base is configured to place the part to be glued, and the positioning mechanism is configured to fix the part to be glued at a first preset position on the base. The gluing mechanism includes a placing platform and a gluing assembly, the placing platform is configured to place glue, and the gluing assembly is configured to absorb glue and move from the placing platform to the first preset position to attach the glue to the part to be glued. The gluing device can fix the part to be glued by the positioning mechanism, and then the gluing assembly attaches the glue placed on the placing platform to the part to be glued located on the base, thereby realizing automatic gluing of the part to be glued, with a faster gluing speed and higher gluing efficiency, thereby improving the production efficiency of the battery. At the same time, automatic gluing reduces manual operations and saves labor costs.

[0065] The gluing device disclosed in the embodiment of the present application can be used to glue battery cells, and can also be used to glue other components. For example, the gluing device provided in the embodiment of the present application can be used to glue end plates.

[0066] The embodiment of the present application provides a glue applying device, Figure 1 This is a schematic structural diagram of the glue application device in some embodiments of the present application. Figure 2 This is a front view of the gluing device of some embodiments of the present application. Figure 3 This is a top view of the adhesive laminating device according to some embodiments of the present application. Figure 4 This is a right side view of the adhesive laminating device in some embodiments of the present application. Figures 1 to 4 The gluing device includes a base 10, a positioning mechanism 20 and a gluing mechanism 30. The base 10 is configured to place a workpiece 100 to be glued, and the positioning mechanism 20 is configured to fix the workpiece 100 to be glued at a first preset position of the base 10.

[0067] Figure 5 This is a schematic structural diagram of the glue-applying mechanism of some embodiments of the present application. Figure 6This is a structural schematic diagram of the gluing mechanism of some embodiments of the present application from another perspective. Figure 7 This is a front view of the adhesive bonding mechanism of some embodiments of the present application. Figures 5 to 7 The glue-applying mechanism 30 includes a placement platform 31 and a glue-applying component 32. The placement platform 31 is configured to place glue, and the glue-applying component 32 is configured to absorb glue 200 and move from the placement platform 31 to a first preset position to attach the glue 200 to the part 100 to be glued.

[0068] In the embodiments of the present application, the adhesive-applying component 100 can be any component requiring adhesive application, for example, a battery cell. The adhesive 200 can be of any type, for example, single-sided tape, double-sided tape, or latex. To facilitate explanation of the adhesive-applying device provided in the embodiments of the present application, the following description uses the battery cell as the adhesive-applying component 100 and double-sided tape as the adhesive. It is understood that the adhesive-applying components 100 and adhesive 200 can also be of other types.

[0069] In the embodiment of the present application, the base 10 is used to place the piece 100 to be glued, provide support for the piece 100 to be glued, and facilitate subsequent gluing of the piece 100 to be glued.

[0070] In the embodiment of the present application, the positioning mechanism 20 secures the workpiece 100 to be glued, so that the workpiece 100 is fixed to the first preset position on the base 10 during the gluing process, preventing the workpiece 100 from moving and affecting the gluing quality. Furthermore, different workpieces 100 can be fixed to the same first preset position during the gluing process, allowing the gluing assembly 32 of the gluing mechanism 30 to glue workpieces 100 in the same position, simplifying the operation.

[0071] In the embodiment of the present application, the first preset position is the position of the member to be glued 100 on the base 10 when gluing is being performed on the member to be glued 100 .

[0072] In the embodiment of the present application, the placement platform 31 is used to place the glue 200 and provides a placement space for the glue 200. The glue applying assembly 32 is movable. The glue applying assembly 32 can move to the placement platform 31 and absorb the glue 200 placed on the placement platform 31; the glue applying assembly 32 can also move to a first preset position and attach the glue 200 to the object 100 to be glued.

[0073] The adhesive application device of the embodiment of the present application can fix the adhesive-applied part 100 through the positioning mechanism 20, and then the adhesive application assembly 32 applies the adhesive 200 placed on the placement platform 31 to the adhesive-applied part 100 located on the base 10, thereby automatically applying adhesive to the adhesive-applied part 100. This achieves a fast and efficient application speed, thereby improving battery production efficiency. Furthermore, the automatic application reduces manual operations and saves labor costs.

[0074] According to some embodiments of the present application, see Figures 1 to 4 The base 10 includes a support 11, a conveying platform 12, and a power assembly 13. The conveying platform 12 is located on the support 11 and is configured to place the adhesive-bonded object 100. The power assembly 13 is connected to the support 11 and is configured to drive the conveying platform 12 to move the adhesive-bonded object 100 to a first predetermined position.

[0075] In an embodiment of the present application, the bracket 11 forms the overall frame of the base 10, the conveying platform 12 is located on the bracket 11, and the bracket 11 provides support for the conveying platform 12. At the same time, the power component 13 is connected to the bracket 11 to ensure the stability of the power component 13.

[0076] In some embodiments of the present application, the shape of the bracket 11 can be set according to requirements. For example, the bracket 11 can be a rectangular frame.

[0077] In some embodiments of the present application, the conveying platform 12 may include a conveyor belt, or the conveying platform 12 may include a chain.

[0078] In an embodiment of the present application, the power assembly 13 may include a motor, or the power assembly 13 may include a cylinder.

[0079] See also Figure 1 、 Figure 2 and Figure 4 The bottom of the bracket 11 is provided with a support foot 111, which can adjust the height of the bracket 11. At the same time, the levelness of the base 10 can be adjusted by adjusting part of the support foot 111.

[0080] In an embodiment of the present application, the conveying platform 12 is driven to move by the power component 13 so that the piece to be glued 100 can be moved to the first preset position. After the piece to be glued 100 moves to the first preset position, the power component 13 is controlled to stop working so that the piece to be glued 100 can be moved to the first preset position, thereby realizing more convenient control over the movement of the piece to be glued 100.

[0081] According to some embodiments of the present application, see Figures 1 to 4 The side of the bracket 11 having the surface of the conveying platform 12 is provided with an anti-falling blocking rod 14.

[0082] In an embodiment of the present application, when the mounting device is in normal use, the anti-falling bar 14 protrudes from the conveying surface of the conveying platform 12 , and the anti-falling bar 14 can prevent the adhesive-bonded piece 100 from falling from the conveying surface of the conveying platform 12 to a certain extent.

[0083] In some embodiments of the present application, the surface of the bracket 11 with the conveying platform 12 is rectangular, and anti-fall bars 14 can be arranged at the four sides of the rectangular surface, that is, the anti-fall bars 14 can surround the surface of the bracket 11, and can reduce the risk of the glued part 100 falling from multiple directions.

[0084] In the embodiment of the present application, the anti-fall blocking rod 14 is provided to reduce the risk of the adhesive-bonded component 100 falling, thereby improving the safety of the adhesive-bonded component 100 during the adhesive bonding process.

[0085] According to some embodiments of the present application, the positioning mechanism 20 is configured to block the movement of the adhesive-coated member 100 and fix the adhesive-coated member 100 at a first preset position.

[0086] In the embodiment of the present application, the positioning mechanism 20 can block the movement of the adhesive member 100 to be applied. In this way, even if the adhesive member 100 to be applied moves to the first preset position, the power assembly 13 does not stop working. The positioning mechanism 20 can fix the adhesive member 100 to be applied at the first preset position, thereby achieving the positioning of the adhesive member 100 to be applied.

[0087] According to some embodiments of the present application, the moving direction of the adhesive member 100 to be applied is the first direction X. Figure 1 and Figure 3 The positioning mechanism 20 includes a first drive assembly 21 and a first stopper 22. The first drive assembly 21 is connected to the bracket 11, and the first stopper 22 is connected to the first drive assembly 21. The first drive assembly 21 is configured to drive the first stopper 22 to move so that at least a portion of the first stopper 22 is located at the second preset position to block the adhesive-applied member 100, so that the adhesive-applied member 100 is located at the first preset position, and the first preset position and the second preset position are adjacent to each other along the first direction X.

[0088] In the embodiment of the present application, the conveying platform 12 conveys the adhesive-bonded member 100 to move, and the moving direction of the conveying platform 12 is the first direction X.

[0089] In the embodiment of the present application, the first preset position and the second preset position are adjacent to each other along the first direction X, and the second preset position is located downstream of the moving path of the member to be glued 100 .

[0090] In the embodiment of the present application, the first driving assembly 21 is connected to the bracket 11 to ensure the stability of the first driving assembly 21 .

[0091] In an embodiment of the present application, the first driving assembly 21 may include a motor, or the first driving assembly 21 may include a cylinder.

[0092] In the embodiment of the present application, the first stopper 22 is connected to the output shaft of the first driving assembly 21 , and the movement of the first stopper 22 can be controlled by the extension and retraction of the output shaft.

[0093] In an embodiment of the present application, during the gluing process, the first driving component 21 drives the first stop block 22 to move to the second preset position. When the piece 100 to be glued moves to the first preset position adjacent to the second preset position, the first stop block 22 can block the movement of the piece 100 to be glued, preventing the piece 100 to be glued from continuing to move under the action of inertia, thereby affecting the accuracy of the positioning mechanism 20 in positioning the piece 100 to be glued.

[0094] According to some embodiments of the present application, Figure 8 This is a partial structural diagram of the adhesive application assembly and the parts to be adhesive-applied in some embodiments of the present application. Figure 8 One of the sides of the glue component 32 facing the first stopper 22 and the side of the first stopper 22 facing the glue component 32 has a positioning hole 33, and the other of the sides of the glue component 32 facing the first stopper 22 and the side of the first stopper 22 facing the glue component 32 has a positioning pin 25. During the process of gluing the glue component 32 to the part 100 to be glued, the positioning pin 25 is located in the positioning hole 33.

[0095] In some embodiments of this application, see Figure 8 The side of the adhesive component 32 facing the first stopper 22 has a positioning hole 33, and the side of the first stopper 22 facing the adhesive component 32 has a positioning pin 25. In other embodiments of the present application, a positioning pin can be provided on the side of the adhesive component 32 facing the first stopper 22, and a positioning hole can be provided on the side of the first stopper 22 facing the adhesive component 32.

[0096] In an embodiment of the present application, during the process of gluing the part to be glued 100 by the gluing component 32, the positioning pin 25 is located in the positioning hole 33. This can be characterized as, during the entire process of gluing the part to be glued 100 by the gluing component 32, there is at least one time period during which the positioning pin 25 is located in the positioning hole 33.

[0097] In the embodiment of the application, positioning pins 25 and positioning holes 33 are provided. During adhesive application, positioning pins 25 are located within positioning holes 33. During each adhesive application process, the relative position of adhesive application assembly 32 and first stopper 22 remains unchanged. Since the relative position of first stopper 22 and object 100 to be adhesively applied is constant, the relative position of adhesive application assembly 32 and object 100 to be adhesively applied remains unchanged. For battery cells of the same model and shape, adhesive application assembly 32 can apply adhesive to the same position of each battery cell during the adhesive application process, resulting in higher accuracy and better adhesive application results.

[0098] According to some embodiments of the present application, Figure 9 This is a partial structural diagram of the first stopper and the adhesive member to be applied in some embodiments of the present application. Figure 1 、 Figure 6 and Figure 9 The first stopper 22 includes a first stopper 221 and a second stopper 222. The first stopper 221 is connected to the first driving assembly 21, and the second stopper 222 is connected to the first stopper 221. The first stopper 221 and the second stopper 222 intersect with each other. When the part to be glued 100 is located in the first preset position, the first stopper 221 and the second stopper 222 are respectively in contact with two adjacent side edges of the part to be glued 100.

[0099] In the embodiment of the present application, the extension direction of the first blocking rod 221 and the extension direction of the second blocking rod 222 can be determined according to the shape of the part 100 to be glued. For example, if the part 100 to be glued is a battery cell, and the two adjacent sides of the battery cell are perpendicular to each other, then the extension direction of the first blocking rod 221 and the extension direction of the second blocking rod 222 are perpendicular.

[0100] Figure 10 This is a partial structural diagram of the first stopper and the adhesive-coated part in some other embodiments of the present application. Figure 10 A chamfer can be set at the end of the second stop rod 222 away from the first stop rod 221, and the opening formed by the first stop rod 221 and the second stop rod 222 is larger, making it easier for the part 100 to be glued to enter the space enclosed by the first stop rod 221 and the second stop rod 222.

[0101] In the embodiment of the present application, the first stopper 22 includes a first stopper 221 and a second stopper 222, and the first stopper 221 and the second stopper 222 are respectively in contact with two adjacent side edges of the workpiece 100 to be glued, so that the contact area between the first stopper 22 and the workpiece 100 is larger, and the positioning mechanism 20 has a better positioning effect on the workpiece 100 to be glued. At the same time, when the workpiece 100 to be glued moves toward the first stopper 221, the first stopper 221 can block the movement of the workpiece 100 to be glued, or when the workpiece 100 to be glued moves toward the second stopper 222, the second stopper 222 can block the movement of the workpiece 100 to be glued, which can better fix the workpiece 100 to be glued and improve the subsequent gluing effect.

[0102] According to some embodiments of the present application, see Figure 1 、 Figures 4 to 7 The positioning mechanism 20 further includes a second drive assembly 23 and a second stopper 24. The second drive assembly 23 is connected to the bracket 11. The second drive assembly 23 and the first drive assembly 21 are located on opposite sides of the bracket 11 along a second direction Y, where the second direction Y intersects the first direction X. The second stopper 24 is connected to the second drive assembly 23. The second drive assembly 23 is configured to drive the second stopper 24 to move so that when the adhesive-applied member 100 is located in the first predetermined position, the adhesive-applied member 100 is located between the first stopper 22 and the second stopper 24.

[0103] In an embodiment of the present application, when the member 100 to be glued is a battery cell, the second direction Y may be perpendicular to the first direction X. In other implementations, the angle between the second direction Y and the first direction X may be less than 90 degrees.

[0104] In the embodiment of the present application, the second driving assembly 23 is connected to the bracket 11 to ensure the stability of the second driving assembly 23 .

[0105] In an embodiment of the present application, the second driving assembly 23 may include a motor, or the second driving assembly 23 may include a cylinder.

[0106] In the embodiment of the present application, the second stopper 24 is connected to the output shaft of the second driving assembly 23, and the movement of the second stopper 24 can be controlled by the extension and retraction of the output shaft.

[0107] In the embodiment of the present application, along the first direction X, the member to be glued 100 is located between the first stopper 22 and the second stopper 24 .

[0108] In an embodiment of the present application, the controller 50 may be communicatively connected to both the first drive assembly 21 and the second drive assembly 23 , and the controller 50 may control the first drive assembly 21 and the second drive assembly 23 to start or stop working.

[0109] In an embodiment of the present application, when the part to be glued 100 is located at the first preset position, the part to be glued 100 is located between the first stop block 22 and the second stop block 24, so that the opposite sides of the part to be glued 100 are blocked, the positioning effect of the part to be glued 100 is better, the possibility of movement of the part to be glued 100 is reduced, and the subsequent gluing effect is improved.

[0110] According to some embodiments of the present application, see Figure 9 As shown in FIG10 , the second stop block 24 includes a third stop rod 241 and a fourth stop rod 242. The third stop rod 241 is connected to the second driving assembly 23, and the fourth stop rod 242 is connected to the third stop rod 241. The third stop rod 241 and the fourth stop rod 242 intersect with each other. When the piece 100 to be glued is located in the first preset position, the third stop rod 241 and the fourth stop rod 242 are respectively in contact with two adjacent side edges of the piece 100 to be glued. The third stop rod 241 is opposite to the first stop rod 221, and the fourth stop rod 242 is opposite to the second stop rod 222.

[0111] In some embodiments of the present application, the extension direction of the first gear rod 221 can be the same as the extension direction of the third gear rod 241, and the extension direction of the first gear rod 221 is parallel to the first direction X, the extension direction of the second gear rod 222 can be the same as the extension direction of the fourth gear rod 242, and the extension direction of the second gear rod 222 is parallel to the second direction Y, and the first direction X is perpendicular to the second direction Y.

[0112] See also Figure 10 A chamfer can be set at the end of the fourth stop rod 242 away from the third stop rod 241, so that the opening formed by the third stop rod 241 and the fourth stop rod 242 is larger, making it easier for the part 100 to be glued to enter the space enclosed by the third stop rod 241 and the fourth stop rod 242.

[0113] In an embodiment of the present application, the first gear rod 221, the second gear rod 222, the third gear rod 241 and the fourth gear rod 242 form a structure similar to a square frame, and the battery cell is located in the square frame, that is, the movement of the battery cell is restricted from four directions, which can better fix the adhesive component 100 and improve the subsequent adhesive effect.

[0114] According to some embodiments of the present application, Figure 11 This is a block diagram of the adhesive laminating device in some other embodiments of the present application. Figure 11The adhesive laminating device further includes a distance sensor 40 and a controller 50. The distance sensor 40 is located on the bracket 11 and is configured to detect the distance between the distance sensor 40 and the workpiece 100 to be adhesively laminated. The controller 50 is communicatively connected to both the distance sensor 40 and the power assembly 13. The distance sensor 40 is further configured to transmit the distance between the distance sensor 40 and the workpiece 100 to the controller 50. The controller 50 is configured to control the power assembly 13 to stop operating if the distance between the distance sensor 40 and the workpiece 100 is less than or equal to a preset distance value.

[0115] In the embodiment of the present application, the distance sensor 40 is located on the bracket 11 to ensure the stability of the distance sensor 40. The distance sensor 40 can be arranged downstream along the moving direction of the adhesive-bonded member 100. In this way, as the adhesive-bonded member 100 moves, the distance between the distance sensor 40 and the adhesive-bonded member 100 detected by the distance sensor 40 gradually decreases.

[0116] In the embodiment of the present application, the preset distance value may be the distance between the first preset position and the distance sensor 40. When the distance between the distance sensor 40 and the workpiece 100 to be glued is equal to the preset distance value, it indicates that the workpiece 100 to be glued has moved to the first preset position. At this time, the control power assembly 13 stops working to prevent the workpiece 100 from continuing to move and affecting the positioning of the workpiece 100 to be glued. When the distance between the distance sensor 40 and the workpiece 100 to be glued is less than the preset distance value, it indicates that the position of the workpiece 100 to be glued has exceeded the first preset position. At this time, the control power assembly 13 stops working and fine-tunes the position of the workpiece 100 to be glued via the first and second gear levers 221 and 222 to achieve positioning of the workpiece 100 to be glued.

[0117] In an embodiment of the present application, the preset distance value can be set according to demand. For example, the preset distance value can be 200 mm.

[0118] In an embodiment of the present application, the controller 50 may be in communication with the power assembly 13 , and the controller 50 may control the power assembly 13 to start or stop working.

[0119] In an embodiment of the present application, the distance between the distance sensor 40 and the workpiece 100 to be glued is detected by the distance sensor 40, and the controller 50 controls the operation of the power component 13 based on the distance between the distance sensor 40 and the workpiece 100 to be glued, thereby realizing automatic control of the position of the workpiece 100 to be glued, reducing labor costs, and making the glue application device more automated.

[0120] According to some embodiments of the present application, see Figure 1 、 Figure 5 and Figure 6The placement platform 31 includes a support plate 311 having a first end 3111 and a second end 3112. The adhesive includes a plurality of adhesive strips 201 arranged side by side. The arrangement direction of the plurality of adhesive strips 201 is the same as the arrangement direction of the first end 3111 and the second end 3112. The plurality of adhesive strips 201 are located between the first end 3111 and the second end 3112, and the adhesive strips 201 closer to the second end 3112 are equidistant from the second end 3112.

[0121] In some embodiments of the present application, the first end 3111 and the second end 3112 can be arranged along the second direction Y, that is, multiple adhesive strips 201 are arranged along the second direction Y, and the adhesive strips 201 extend along the first direction X, so that the sides of the battery cell extending along the first direction X can be glued.

[0122] In other embodiments of the present application, the first end 3111 and the second end 3112 can be arranged along the first direction X, that is, multiple adhesive strips 201 are arranged along the first direction X, and the adhesive strips 201 extend along the second direction Y, so that the sides of the battery cells extending along the second direction Y can be glued.

[0123] In an embodiment of the present application, each time the glue is applied, the glue assembly 32 can absorb one of the multiple glue strips 201 and attach it to the battery cell. After the glue is applied, the remaining glue strips 201 can move toward the second end 3112, so that the distance between the glue strip 201 close to the second end 3112 and the second end 3112 among the multiple glue strips 201 is always consistent.

[0124] In an embodiment of the present application, the rubber strip 201 is placed on the support plate 311 to provide a placement space for the rubber strip 201. At the same time, the distance between the rubber strip 201 close to the second end 3112 and the second end 3112 among the multiple rubber strips 201 is equal, that is, multiple glue application is performed, and the relative position of the rubber strip 201 close to the second end 3112 and the second end 3112 among the multiple rubber strips 201 is certain. The glue application component 32 can always adsorb the rubber strip 201 at the second end 3112 during the process of adsorbing the rubber strip 201, so that the trajectory of the glue application component 32 is the same each time it moves, and it is simpler to control the movement of the glue application component 32.

[0125] According to some embodiments of the present application, Figure 12 This is a partial bottom view of the adhesive application assembly and the part to be adhesive-applied in some embodiments of the present application. Figure 12The placement platform 31 also includes a baffle 312 and a first elastic element 313. The baffle 312 and the rubber strip 201 are located on the same side of the support plate 311, with the baffle 312 close to the second end 3112. Multiple rubber strips 201 are located between the first end 3111 and the baffle 312. The rubber strips 201 close to the baffle 312 among the multiple rubber strips 201 are against the baffle 312. The first elastic element 313 is located on the side of the support plate 311 away from the baffle 312, and the first elastic element 313 is connected to the support plate 311. The adhesive also includes release paper 202, and multiple rubber strips 201 are all located on the release paper 202. The portion of the release paper 202 with the rubber strip 201 is in contact with the surface of the support plate 311, and the other portion of the release paper 202 passes through the second end 3112 and is connected to the first elastic element 313.

[0126] In an embodiment of the present application, the side of the baffle 312 can be connected to the side of the support plate 311, and there is a gap between the middle of the baffle 312 and the middle of the support plate 311, so that the release paper 202 can pass through the gap between the baffle 312 and the support plate 311 and then pass through the second end 3112 to connect with the first elastic element 313.

[0127] In one implementation of the present application, the first elastic element 313 may be a spring, and one end of the spring connected to the release paper 202 has a hook to facilitate the connection between the spring and the release paper 202 .

[0128] In the embodiment of the present application, the first elastic element 313 has elastic force, and another portion of the release paper 202 is connected to the first elastic element 313. The first elastic element 313 can pull the release paper 202 toward the second end 3112, keeping the release paper 202 flat and facilitating the adsorption of the adhesive strip on the release paper 202. Simultaneously, the adhesive strip 201 on the release paper 202 can move with the release paper 202, so that the adhesive strip 201 near the stop bar 312 abuts against the stop bar 312. The abutment between the adhesive strip 201 and the stop bar 312 limits the movement of the adhesive strip 201, thereby limiting the movement of the release paper 202.

[0129] In the embodiment of the present application, after the adhesive strip 201 is attached to the adhesive strip 201 by the adhesive application assembly 32, a gap exists between the adhesive strip 201 and the stop bar 312. At this point, the stop bar 312 cannot restrict the movement of the adhesive strip 201. Under the elastic force of the first elastic element 313, the release paper 202 moves toward the second end 3112, and the adhesive strip 201 on the release paper 202 moves along with the release paper 202, causing the adhesive strip 201 near the stop bar 312 to abut against the stop bar 312. The distance between the stop bar 312 and the second end 3112 is constant, thereby ensuring a constant distance between the adhesive strip 201 near the second end 3112. This eliminates the need for manual control of the movement of the adhesive strip 201, reduces labor costs, and enables automated adhesive application.

[0130] After the gluing is completed, the release paper 202 can be directly recovered from the first elastic element 313 , which is convenient and quick.

[0131] According to some embodiments of the present application, see Figure 12 The first elastic element 313 is connected to the support plate 311 through a first adjusting bolt 314 , and the first adjusting bolt 314 is used to adjust the distance between the first elastic element 313 and the second end 3112 .

[0132] Illustratively, a mounting protrusion 3113 may be provided on the surface of the support plate 311 facing away from the blocking bar 312 , and the first adjusting bolt 314 is connected to the mounting protrusion 3113 to achieve connection between the first adjusting bolt 314 and the support plate 311 .

[0133] Exemplarily, one end of the first adjusting bolt 314 connected to the first elastic element 313 has a mounting hole, and one end of the first elastic element 313 connected to the first adjusting bolt 314 has a hook, which extends into the mounting hole to realize the connection between the first adjusting bolt 314 and the first elastic element 313.

[0134] In the embodiment of the present application, the distance between the first adjusting bolt 314 and the second end 3112 can be adjusted by screwing the first adjusting bolt 314 , thereby adjusting the distance between the first elastic element 313 and the second end 3112 .

[0135] In the embodiment of the present application, the first elastic element 313 uses elastic force to pull the release paper 202 to move. As the number of adhesive applications increases, the release paper 202 moves toward the first elastic element 313, and the first elastic element 313 gradually recovers its deformation. When the first elastic element 313 returns to a non-elastic state, the first elastic element 313 can no longer provide elastic force to pull the release paper 202 to move. At this time, the distance between the first elastic element 313 and the second end 3112 can be adjusted by screwing the first adjustment bolt 314, thereby increasing the distance between the first elastic element 313 and the second end 3112. The release paper 202 will pull the first elastic element 313, and the first elastic element 313 can regenerate elastic force, so that the first elastic element 313 can use this elastic force to pull the release paper 202 to move.

[0136] According to some embodiments of the present application, see Figure 5 and Figure 6 The placement platform 31 also includes a second elastic element 315, which is located on the same side of the support plate 311 as the rubber strip 201. The second elastic element 315 is connected to the support plate 311, and the second elastic element 315 abuts against one end of the rubber strip 201 away from the second end 3112.

[0137] In one implementation of the present application, the second elastic element 315 may include a spring and a push rod, with both ends of the spring respectively abutting against the first end 3111 and the rubber strip 201 , and the spring pushes the push rod so that the push rod abuts against the rubber strip 201 .

[0138] In the embodiment of the present application, the second elastic element 315 has elastic force to push the rubber strip 201 to move toward the second end 3112 , so that the distance between the rubber strip 201 close to the second end 3112 and the second end 3112 is always equal.

[0139] According to some embodiments of the present application, the second elastic element 315 is movably connected to the support plate 311 via a second adjusting bolt 316 , and the second adjusting bolt 316 is used to adjust the distance between the second elastic element 315 and the second end 3112 .

[0140] In some embodiments of the present application, the second elastic element 315 can be placed on the support plate 311. The second elastic element 315 has a threaded hole. From the side of the second elastic element 315 away from the support plate 311, a second adjustment bolt 316 is threadedly connected to the threaded hole and then passes through the threaded hole to abut against the support plate 311. The second elastic element 315 and the support plate 311 are connected by friction between the second adjustment bolt 316 and the support plate 311. When it is necessary to adjust the distance between the second elastic element 315 and the second end 3112, the second adjustment bolt 316 is tightened so that the second adjustment bolt 316 does not abut against the support plate 311. After moving the second elastic element 315 to the desired position, the second adjustment bolt 316 is tightened again in the opposite direction so that the second adjustment bolt 316 abuts against the support plate 311, thereby reconnecting the second elastic element 315 and the support plate 311.

[0141] In other embodiments of the present application, the second elastic element 315 has a through hole, and the support plate 311 has multiple threaded holes at corresponding positions. The second adjustment bolt 316 passes through the through hole and is threadedly connected to the threaded hole to achieve the connection between the second elastic element 315 and the support plate 311. When it is necessary to adjust the distance between the second elastic element 315 and the second end 3112, the second adjustment bolt 316 is screwed to disconnect the second elastic element 315 from the support plate 311. After the second elastic element 315 is moved to the desired position, the second adjustment bolt 316 is then passed through the through hole and is threadedly connected to the threaded hole to reconnect the second elastic element 315 and the support plate 311.

[0142] In the embodiment of the present application, the second elastic element 315 pushes the rubber strip 201 through elastic force. As the number of adhesive applications increases, the rubber strip 201 moves toward the second end 3112, and the second elastic element 315 gradually recovers its deformation. When the second elastic element 315 returns to a state without elastic force, the second elastic element 315 may be unable to push the rubber strip 201. In this case, the distance between the second elastic element 315 and the second end 3112 can be adjusted by screwing the second adjustment bolt 316, thereby increasing the deformation of the second elastic element 315 and the elastic force provided by the second elastic element 315, so that the second elastic element 315 can push the rubber strip 201 to move.

The power assembly is connected to the support and configured to drive the conveying platform to move.

[0180] In an embodiment of the present application, the conveying platform is driven to move by a power component so that the battery cell can be moved to a first preset position. After the battery cell moves to the first preset position, the power component is controlled to stop working so that the battery cell can be moved to the first preset position, thereby realizing more convenient control over the movement of the adhesive-bonded part.

[0184] In the embodiment of the present application, the distance sensor is located on the bracket to ensure the stability of the distance sensor.

[0193] In an embodiment of the present application, when the battery cell is located at the first preset position, the battery cell is located between the first block and the second block, so that the opposite sides of the battery cell are blocked, which has a better positioning effect on the battery cell, reduces the possibility of battery cell movement, and improves the subsequent gluing effect.
