[0002] In today's battery manufacturing industry, automated production lines have become an irreversible trend in order to further improve production efficiency and ensure high-quality product standards. In this process, fully automated adhesive application technology plays a crucial role, serving as an indispensable key step in battery production. Currently, the industry commonly employs two main adhesive application solutions: the first is the fully automated solution, which uses a roll-to-roll mechanism for peeling and feeding adhesive, a variable-pitch mechanism for precise battery positioning, and a suction cup mechanism for adhesive pickup and application, achieving efficient and precise adhesive application; the second is the manual adhesive application solution used in the early stages of pilot production lines for prototyping. However, in practice, the manual adhesive application solution has many shortcomings, such as alignment deviations, inaccurate coverage areas, and bending or wrinkling of the foam adhesive. These problems not only affect the product's appearance but may also lead to thickness deviations during PACK pre-pressing, thus impacting the overall product quality.

[0003] Therefore, how to effectively solve these problems and improve the accuracy and efficiency of manual adhesive application has become an important issue that urgently needs to be addressed in the battery manufacturing industry. Utility Model Content

[0048] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0049] This utility model provides an adhesive applicator, comprising:

[0050] The positioning unit 1 includes a base 11 and a pushing component 12. The pushing component 12 is fixedly placed on the base 11 and is used to adjust the position of the battery on the base 11. The base 11 is provided with a rotating shaft 111, which is located at one end of the base 11 away from the pushing component 12.

[0051] The adhesive application unit 2 is rotatably connected to one side of the base 11 via a rotating shaft 111. The adhesive application unit 2 can move closer to or away from the base 11 with the rotating shaft 111 as the fulcrum.

[0052] The magnetic suction unit 3 is placed at the end of the adhesive unit 2 away from the base 11 and is used to peel off the release paper 41 on the foam adhesive 4 in the adhesive unit 2.

[0053] The base 11 is the foundation of the adhesive application device, supporting the entire device and the battery. The pushing component 12 is fixed to the base 11 and is used to adjust the battery's position on the base 11. By pushing the component 12, precise positioning of the battery during the adhesive application process is ensured, reducing errors caused by manual alignment. A rotating shaft 111 is located at one end of the base 11, away from the pushing component 12. It acts as a fulcrum, allowing the adhesive application unit 2 to rotate around this shaft.

[0054] The adhesive application unit 2 is connected to one side of the base 11 via a rotating shaft 111, allowing it to move around the rotating shaft 111 as a fulcrum. By moving closer to or further away from the base 11, the adhesive application operation on the battery surface can be achieved, making the adhesive application process more flexible and precise.

[0055] The magnetic unit 3 is located at the end of the adhesive unit 2 away from the base 11. Its function is to peel off the release paper 41 from the foam adhesive 4 in the adhesive unit 2. During the adhesive application process, the foam adhesive 4 is usually covered by a layer of release paper 41. The function of the magnetic unit 3 is to easily peel off this layer of paper so that the foam adhesive 4 can be attached to the battery.

[0056] Furthermore, the pushing component 12 includes a first fixing member 121, a push plate 122, and a fixing shaft 123.

[0057] The push plate 122 is vertically placed on the base 11; the first fixing member 121 is placed on the side of the push plate 122 away from the rotating shaft 111; the fixing shaft 123 is fixed on the side of the push plate 122 away from the rotating shaft 111, passes through the first fixing member 121, and is threadedly connected to the first fixing member 121.

[0058] Specifically, the first fixing member 121 provides a fixed point for connection to the push plate 122 via the fixing shaft 123. The push plate 122 is part of the pushing assembly 12 and is vertically mounted on the base 11. The push plate 122 is in direct contact with the battery and adjusts the position of the battery on the base 11 by moving the pushing assembly 12. The fixing shaft 123 is the element connecting the push plate 122 and the first fixing member 121. It is fixed to the side of the push plate 122 away from the rotation shaft 111 and passes through the first fixing member 121. The fixing shaft 123 and the first fixing member 121 are connected by a thread, which allows for precise adjustment and fixation of the push plate 122.

[0059] When the battery position needs to be adjusted, the operator can rotate the fixing shaft 123. Due to the threaded connection between the fixing shaft 123 and the first fixing member 121, rotating the fixing shaft 123 causes the push plate 122 to move along the direction of the fixing shaft 123 (usually vertically). This movement can precisely push the battery, causing it to move back and forth or up and down on the base 11 until the desired positioning position is reached. Once the battery position is determined, the fixing shaft 123 can be locked to ensure that the push plate 122 and the battery remain fixed and do not move during the adhesive application process.

[0060] Furthermore, it also includes a second fixing member 124 and a guide shaft 125; the second fixing member 124 is fixedly placed on the base 11 and is located on the same horizontal line as the first fixing member 121, and the guide shaft 125 passes through the second fixing member 124; the second fixing member 124 is provided with an adjusting member 126, which is used to adjust the length of the guide shaft 125 passing through the second fixing member 124.

[0061] Specifically, the second fixing member 124 is another fixing element, fixed to the base 11 and located on the same horizontal line as the first fixing member 121. This design aims to provide a stable support structure that works in conjunction with the first fixing member 121 to ensure stable and precise movement of the push plate 122. A guide shaft 125 passes through the second fixing member 124 to guide the movement of the push plate 122. An adjusting member 126 is located on the second fixing member 124, and its function is to adjust the length of the guide shaft 125 passing through the second fixing member 124. By adjusting the length of the guide shaft 125, the position of the push plate 122 can be finely adjusted, thereby achieving precise adjustment of the battery position.

[0062] Since the fixed shaft 123 and the push plate 122 are fixedly connected, when the battery position is determined, the operator can use the adjusting member 126 to change the length of the guide shaft 125 passing through the second fixing member 124, thereby adjusting the push plate 122 to a horizontal position. This adjustment allows for precise control of the battery position, ensuring high consistency in the adhesive application process. Once the battery position is adjusted, the adjusting member 126 can be fixed to maintain the relative position of the push plate 122 and the battery until the adhesive application is complete.

[0063] Furthermore, a protective plate 127 is provided on the side of the push plate 122 away from the push assembly 12, and the protective plate 127 is fixedly connected to the push plate 122.

[0064] Specifically, the protection plate 127 is a component attached to the side of the push plate 122 away from the push assembly 12, and it is fixedly connected to the push plate 122. The main function of the protection plate 127 is to protect the battery from damage during the pushing process, and at the same time, it can also ensure the stability of the push plate 122 during operation.

[0065] In one possible embodiment of this invention, during the process of pushing the battery to adjust its position, the protective plate 127 can prevent the battery surface from directly contacting the push plate 122 or other components, reducing potential scratches or wear on the battery surface. The flat surface of the protective plate 127 helps to provide uniform pressure when the push plate 122 pushes the battery, thereby ensuring smooth battery movement and avoiding battery displacement or damage due to uneven pressure. The fixed connection between the protective plate 127 and the push plate 122 enhances the stability of the entire push plate 122 structure, making the push plate 122 more robust and less prone to deformation during operation. In other possible embodiments of this invention, the protective plate 127 may also have an auxiliary positioning function, helping the operator to more accurately judge the position of the battery, especially in adhesive application operations that require precise alignment.

[0066] Furthermore, the adhesive application unit 2 includes two flip bars 21. One end of each flip bar 21 is rotatably connected to the rotating shaft 111 and is limited by an elastic element 25; the other end extends away from the rotating shaft 111. The two flip bars 21 are respectively placed at both ends of the rotating shaft 111, and the two flip bars 21 are also fixedly connected by multiple connecting bars 26.

[0067] Specifically, the flip strip 21 is part of the adhesive application unit 2. One end of each flip strip 21 is fixed to the rotating shaft 111 via a rotatable connection, while the other end extends away from the rotating shaft 111. The design of the flip strip 21 allows it to flip around the rotating shaft 111. Connecting strips 26 are used to fix two flip strips 21 together, and they are located between the two flip strips 21. Through these connecting strips 26, the two flip strips 21 form a stable structure and participate in the adhesive application action together. When the adhesive application unit 2 needs to move closer to or further away from the base 11 for adhesive application, the flip strip 21 can flip around the rotating shaft 111, which allows the adhesive application unit 2 to flexibly adjust its position to adapt to batteries of different thicknesses or different adhesive application requirements.

[0068] The elastic element 25 is used to limit the rotation strip 21. It can be a spring, a rubber pad, or other elastic component. The function of the elastic element 25 is to ensure that the rotation strip 21 does not move excessively during rotation, maintaining the stability and consistency of the adhesive application unit 2. In one possible embodiment of this invention, the elastic element 25 is a steel wire elastic ring. The position of the rotation strip 21 is limited by the steel wire elastic ring. Every two steel wire elastic rings limit the position of one rotation strip 21, thereby achieving separate positioning of the four positions of the two foam adhesive strips.

[0069] The flip bars 21 on both sides are fixedly connected by multiple connecting bars 26, forming a sturdy frame. This helps maintain the stability of the adhesive application unit 2 and ensures the accuracy of the adhesive application process. Since the two flip bars 21 are respectively located at both ends of the rotating shaft 111 and connected by the connecting bars 26, this symmetrical design helps to evenly distribute force during adhesive application, avoiding deviations caused by unilateral force application. In one possible embodiment of this invention, the flip bars 21 can be adjusted according to the width of the battery, allowing the adhesive application unit 2 to adapt to batteries of different sizes.

[0070] In one possible embodiment of this utility model, the adhesive unit 2 also has a passive limiting function. When the flip bar 21 is flipped to 90°, the edge of the base 11 will prevent the flip bar 21 from continuing to flip. At this time, the foam adhesive 4 is completely adhered to the battery surface, and since the depth of the first slot 241 is 0.5mm less than the foam adhesive 4, when the flip bar 21 is flipped to 90°, the foam adhesive 4 is just compressed by 0.5mm, which can ensure that the foam adhesive 4 can be firmly attached to the heat insulation pad 5 on the battery.

[0071] Furthermore, it also includes a bottom support plate 22 and a middle support plate 23; the bottom support plate 22 is placed on the connecting strip 26 near the rotating shaft 111; the middle support plate 23 is placed on the connecting strip 26 located in the middle, and is used to place the heat insulation pad 5.

[0072] Specifically, the bottom support plate 22 is located on the connecting strip 26 near the rotating shaft 111. The bottom support plate 22 provides a supporting surface to support the bottom of the heat insulation pad 5, ensuring that the heat insulation pad 5 remains stable during adhesive application and does not move due to gravity or operating force. The middle support plate 23 is located in the middle of the connecting strip 26 and is designed to hold the heat insulation pad 5. The position and size of the middle support plate 23 should match the heat insulation pad 5 to ensure accurate placement during adhesive application. The presence of the bottom support plate 22 ensures the stability of the heat insulation pad 5 during adhesive application, reducing adhesive placement deviations caused by movement of the heat insulation pad 5. The middle support plate 23 provides a fixed placement position for the heat insulation pad 5, helping the operator to accurately align the heat insulation pad 5 and improve the accuracy of adhesive application.

[0073] By using a dedicated support plate, the operation process can be simplified, reducing the operator's preparation work when placing the heat insulation pad 5, thereby improving the overall adhesive application efficiency. The support plate design helps ensure the accurate placement of the heat insulation pad 5 and the foam adhesive 4, thus improving the adhesive quality of the final product.

[0074] Furthermore, a positioning plate 24 is provided on the surface of the flip bar 21 near the base 11. The positioning plate 24 is fixedly connected to the flip bar 21 and is used to place the foam adhesive 4.

[0075] Furthermore, the positioning plate 24 is recessed downward on the surface away from the flip strip 21 to form a first groove 241, which is used to fix the foam adhesive 4; the positioning plate 24 is recessed inward on the side near the middle support plate 23 to form a second groove 242, which is used to fix the heat insulation pad 5.

[0076] The positioning plate 24 is fixedly connected to the surface of the flip bar 21 near the base 11. Its main function is to provide a flat surface for placing the foam adhesive 4. The positioning plate 24 ensures the correct position of the foam adhesive 4 during the adhesive application process, facilitating subsequent adhesive application operations.

[0077] The first slot 241 is located on the surface of the positioning plate 24 away from the flip strip 21 and is recessed downwards. This slot is designed to fix the foam adhesive 4, ensuring that the foam adhesive 4 will not shift during the application process. When the foam adhesive 4 is placed in the first slot 241, it can be accurately positioned and fixed, thus maintaining consistency and stability during application. The second slot 242 is located on the side of the positioning plate 24 near the central support plate 23 and is recessed inwards. This slot is used to fix the heat insulation pad 5, ensuring that the heat insulation pad 5 is accurately positioned during the application process. By placing the heat insulation pad 5 in the second slot 242, the relative position of the heat insulation pad 5 and the battery can be kept unchanged, improving the accuracy of the application.

[0078] The design of the first slot 241 and the second slot 242 allows for precise fixation of the foam adhesive 4 and the heat insulation pad 5, reducing positional deviations during the adhesive application process. Fixing the materials with the slots enables rapid adhesive application without additional alignment steps, thus improving production efficiency. The fixed slots help ensure consistency in each adhesive application, reducing defects caused by material displacement and improving overall product quality.

[0079] In one embodiment of this utility model, the foam adhesive 4 is inserted into the first slot 241. The release paper 41 on the surface of the foam adhesive 4 is peeled off, and then the heat insulation pad 5 is placed on the middle support plate 23. At this time, the edge of the heat insulation pad 5 is inserted into the second slot 242, and the PET film sealing edge of the heat insulation pad 5 is just adhered to the foam adhesive 4.

[0080] Furthermore, the magnetic suction unit 3 is placed at the end of the flip bar 21 away from the rotating shaft 111; the magnetic suction unit 3 includes a clamping member 31, one end of which is rotatably fixed to the flip bar 21 via a movable shaft 32; the surface of the clamping member 31 away from the movable shaft 32 and close to the positioning plate 24 is provided with a first adsorption member 311, and the surface away from the positioning plate 24 is provided with a gripping member 312.

[0081] The magnetic suction unit 3 is located at the end of the flip bar 21 furthest from the rotating shaft 111, meaning it is located at the operating end of the adhesive application unit 2 for easy use during adhesive application. The clamping member 31 is part of the magnetic suction unit 3, with one end rotatably fixed to the flip bar 21 via a movable shaft 32. This allows the clamping member 31 to rotate around the movable shaft 32, thereby adjusting its position and angle. The movable shaft 32 serves to fix the clamping member 31 to the flip bar 21 while allowing the clamping member 31 to rotate within a certain range, providing operational flexibility.

[0082] The first adsorption element 311 is located at the end of the clamping element 31 away from the movable shaft 32 and close to the surface of the positioning plate 24. Its function is to magnetically attract the release paper 41 on the foam adhesive 4, allowing for easy peeling off of the release paper 41 during application, exposing the adhesive side of the foam adhesive 4. The gripping element 312 is located on the surface of the clamping element 31 away from the positioning plate 24; it is the part used by the operator to hold and operate the magnetic unit 3. The gripping element 312 is designed to facilitate the operator's application of force, thereby effectively using the magnetic unit 3. The design of the first adsorption element 311 makes peeling off the release paper 41 from the foam adhesive 4 quick and convenient, improving application efficiency.

[0083] Since the clamping member 31 can rotate around the movable axis 32, the operator can adjust the position and angle of the magnetic suction unit 3 as needed to adapt to different adhesive application scenarios. The grip member 312 provides a good grip, allowing the operator to precisely control the magnetic suction unit 3 and ensure the accuracy of the adhesive application process.

[0084] Furthermore, the positioning plate 24 has a groove 243 at one end away from the rotating shaft 111, and a second adsorption member 313 is provided in the groove 243; the second adsorption member 313 cooperates with the first adsorption member 311 to fix the release paper 41 on the foam adhesive 4.

[0085] The groove 243 is located at the end of the positioning plate 24 away from the rotating shaft 111, and is designed to accommodate the second adsorption member 313. The position and shape of the groove 243 should match the second adsorption member 313 so that the second adsorption member 313 can be stably placed in the groove 243. The second adsorption member 313 is placed in the groove 243 of the positioning plate 24, and its function is to cooperate with the first adsorption member 311 to fix the release paper 41 on the foam adhesive 4.

[0086] Through the combined action of the first adsorption member 311 and the second adsorption member 313, the release paper 41 on the foam adhesive 4 can be more firmly fixed, reducing possible deviations or damage during the peeling process.

[0087] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
