[0056] To better understand the embodiments of this application, the following is combined with... Figures 1 to 11 The embodiments of this application will be described in detail.

[0057] like Figures 1 to 8As shown, this application provides a folding device 1, including a positioning component 11 and a folding component 12. The folding component 12 is disposed on one side of the positioning component 11, and includes a folding element 121 and a pressing element 122. The folding element 121 includes a first through hole 1211 and a second through hole 1212 that are connected together. The diameter of the first through hole 1211 is smaller than the diameter of the second through hole 1212, so as to form a folding surface 1213 between the first through hole 1211 and the second through hole 1212. The pressing element 122 is movably disposed in the first through hole 1211.

[0058] The positioning component 11 refers to the component used to position the cylindrical battery 2, which is the product awaiting adhesive bonding. Specifically, the positioning component 11 can be a fixing device such as a gripper, a negative pressure adsorption component, or a magnetic adsorption component, or a positioning device such as a V-shaped positioning block. By setting the positioning component 11, the cylindrical battery 2, which is the product awaiting adhesive bonding, has a definite position in the adhesive bonding device 1, which facilitates the subsequent adhesive bonding operation.

[0059] The folding component 121 includes a first through hole 1211 and a second through hole 1212 that are connected together, specifically, as shown in the figure. Figure 3 , 4 As shown in Figures 7 and 8, a first through hole 1211 and a second through hole 1212 are disposed through the folding assembly 121 along a first direction, and the geometric centers of the first through hole 1211 and the second through hole 1212 coincide along the first direction X. The diameter of the first through hole 1211 is smaller than the diameter of the second through hole 1212, so as to form a folding surface 1213 between the first through hole 1211 and the second through hole 1212. In addition, the second through hole 1212 is a cylindrical hole with a diameter larger than the outer surface of the cylindrical battery 2. In this way, when the positioning assembly 11 and the folding assembly 12 approach each other, the end of the cylindrical battery 2 wrapped with tape 3 gradually approaches the folding assembly 12 and enters the second through hole 1212. The part of tape 3 extending out of the end of the cylindrical battery 2 gradually bends inward and gathers under the obstruction of the folding surface 1213, realizing the bending function of tape 3 at the end of the cylindrical battery 2.

[0060] The pressing component 122 is movably disposed in the first through hole 1211. Specifically, the pressing component 122 passes through the first through hole 1211, so that the pressing component 122 can move in the first through hole 1211. Thus, the end of the pressing component 122 is used to press and stick the inwardly bent and gathered tape 3 to the end face of the cylindrical battery 2, thereby improving the adhesion of the tape 3 at the end of the cylindrical battery 2.

[0061] The distance between the positioning component 11 and the folding component 12 is adjustable, meaning that the positioning component 11 and the folding component 12 can move closer to or further away from each other along the first direction X to achieve the folding and loading / unloading of the cylindrical battery 2. Specifically, in some embodiments, either the positioning component 11 or the folding component 12 is movable along the first direction X; while in other embodiments, both the positioning component 11 and the folding component 12 are movable along the first direction X. It should be noted that the movable setting of the positioning component 11 and / or the folding component 12 along the first direction X can be achieved by a guide rail slider mechanism or by a lead screw mechanism; this application embodiment does not limit this.

[0062] By setting up a positioning component 11 and a folding component 12, when the positioning component 11 and the folding component 12 approach each other, the cylindrical battery 2 positioned on the positioning component 11 gradually approaches the folding component 12, causing the adhesive tape 3 extending from the end of the cylindrical battery 2 to enter the second through hole 1212. Under the obstruction of the folding surface 1213, it is bent inward. Then, the pressing component 122 moves along the first through hole 1211 towards the positioning component 11, squeezing and applying the bent adhesive tape 3 to the end of the cylindrical battery 2. That is, the folding and pressing actions can be performed continuously in the same station without the need to switch workpieces, which greatly improves the end-face adhesive application efficiency of the cylindrical battery 2.

[0063] like Figure 3 , 4 As shown in Figures 7 and 8, in some embodiments, the diameter of the second through hole 1212 gradually increases in the direction away from the first through hole 1211.

[0064] The diameter of the second through hole 1212 gradually increases along the direction away from the first through hole 1211. That is, the second through hole 1212 is in the shape of a trumpet with a gradually increasing opening along the first direction X. In this way, the inclined setting of the hole wall of the second through hole 1212 gradually narrows inward can guide the tape 3 extending from the end of the cylindrical battery 2 to gradually bend and narrow inward under the guidance of the hole wall of the second through hole 1212, thereby improving the quality of the adhesive on the end of the cylindrical battery 2.

[0065] like Figure 3 and Figure 7 As shown, in some embodiments, the first through hole 1211 and the second through hole 1212 are provided with an arc transition to form an arc-shaped folded surface 1213.

[0066] By setting the folding surface 1213 as an arc-shaped surface, the bent part formed after the tape 3 is bent can be arc-shaped, which can prevent the tape 3 from crease or even tear due to excessive stress at the bending position, and further improve the adhesive quality of the end face of the cylindrical battery 2.

[0067] like Figures 1 to 3As shown, in some embodiments, the folding assembly 12 further includes a folding mounting member 123, with the folding member 121 disposed on the folding mounting member 123 and the pressing member 122 passing through the folding mounting member 123.

[0068] The folding component 121 is disposed on the folding mounting component 123. Specifically, the folding component 121 is disposed on the side of the folding mounting component 123 near the positioning component 11, so that the cylindrical battery 2 on the positioning component 11 can smoothly enter the second through hole 1212 of the folding component 121 without obstruction.

[0069] The pressing component 122 passes through the folded adhesive mounting component 123, allowing the pressing component 122 to move relative to the folded adhesive mounting component 123 along the first direction X, thereby approaching the positioning component 11 and realizing the pressing function of the cylindrical battery 2.

[0070] like Figure 3 As shown, in some embodiments, the pressure-adhesive member 122 includes a body portion 1221 and a pressure-adhesive portion 1222 disposed at one end of the body portion 1221, the diameter of the pressure-adhesive portion 1222 being larger than the diameter of the body portion 1221; the folding adhesive mounting member 123 includes a mounting hole 1231, the body portion 1221 passing through the mounting hole 1231, the diameter of the mounting hole 1231 being smaller than the diameter of the first through hole 1211, so as to limit the pressure-adhesive portion 1222.

[0071] The mounting hole 1231 is a through hole provided in the folded adhesive mounting member 123 along the first direction X, and the mounting hole 1231 and the first through hole 1211 are concentrically arranged along the first direction X, so that the body part 1221 of the adhesive pressing member 122 can move along the first direction X in the mounting hole 1231, thereby pushing the adhesive pressing member 1222 to move along the first direction in the first through hole 1211, thereby approaching the positioning component 11 and realizing the adhesive pressing function of the cylindrical battery 2.

[0072] The diameter of the mounting hole 1231 is smaller than the diameter of the first through hole 1211, so that a step portion for limiting is formed between the mounting hole 1231 and the first through hole 1211. In addition, the pressure-adhesive part 122 is configured as two parts: a body part 1221 and a pressure-adhesive part 1222, so that when the pressure-adhesive part 1222 moves in the first through hole 1211, it can be limited in the step portion and will not come out of the first through hole 1211.

[0073] In some embodiments, the pressing part 1222 can be made of an elastic material such as rubber, which can reduce the impact on the end of the cylindrical battery 2 during the pressing process and ensure the production quality of the cylindrical battery 2.

[0074] like Figures 1 to 3 As shown, in some embodiments, the folding assembly 12 further includes a sleeve 124 disposed on the side of the folding mounting member 123 away from the folding member 121, and the pressing member 122 passes through the sleeve 124.

[0075] The sleeve 124 is located on the side of the folding and mounting component 123 away from the folding component 121. By setting the sleeve 124 and inserting the pressing component 122 into the sleeve 124, the guiding and limiting ability of the pressing component 122 in the first direction X can be improved, ensuring that it moves smoothly along the first direction X and avoiding blockage or jamming caused by the skewness of the pressing component 122 during the movement.

[0076] like Figures 1 to 3 As shown in Figures 11 and 12, in some embodiments, the folding assembly 12 further includes a pressing mounting member 125 disposed on the side of the folding mounting member 123 away from the folding member 121, and a pressing member 122 disposed on the side of the pressing mounting member 125 near the folding mounting member 123.

[0077] By setting the pressure-adhesive mounting component 125, both ends of the pressure-adhesive component 122 are limited, which can further improve the limiting ability of the pressure-adhesive component 125 and ensure that it moves strictly along the first direction X.

[0078] like Figure 1 , 9 As shown in Figures 1 and 10, in some embodiments, the folding device 1 further includes a frame 13, a connector 14, and a first drive member 15. The frame 13 is provided with a first guide rail 131; the connector 14 is slidably disposed on the first guide rail 131, and the folding assembly 12 is disposed on the connector 14; the first drive member 15 is fixedly disposed on the frame 13, and the first drive member 15 is drivenly connected to the connector 14.

[0079] The frame 13 is provided with a first guide rail 131. Specifically, the frame 13 is provided with a first guide rail extending along the first direction X. The connector 14 is slidably disposed on the first guide rail 131, so that the connector 14 can be moved along the first direction X.

[0080] The folding component 12 is disposed on the connector 14. Specifically, the folding component 12 and the connector 14 can be connected by non-removable methods such as welding or bonding, or by detachable methods such as bolt connection or snap-fit ​​connection. This application embodiment does not limit this. By setting the connector 14, the folding component 12 can be moved along the first direction X, and the positioning component 12 and the folding component 12 can move closer and further away from each other along the second direction X.

[0081] The first driving component 15 can be a power-providing component such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder; this embodiment does not limit this. The first driving component 15 is fixedly mounted on the frame 13 and is drivenly connected to the connecting component 14. Specifically, the body of the first driving component 15 is fixedly mounted on the frame 13, while its output end is connected to the connecting component 14 to drive the connecting component 14 and the folding assembly 12 to move relative to the frame 13 along the first direction X.

[0082] During the folding process, since the cylindrical battery 2 is positioned in the positioning component 11, compared with the movable setting of the positioning component 11, the movable setting of the folding component 11 can make the cylindrical battery 2 stationary in the folding device 1, thereby enhancing the positioning accuracy of the cylindrical battery 2 in the folding device 1 and improving the accuracy and quality of its folding.

[0083] like Figure 1 and 2 As shown, in some embodiments, the connector 14 is provided with a second guide rail 141, the adhesive pressing mounting component 125 is slidably disposed on the second guide rail 141, and the adhesive folding assembly 12 further includes a second driving component 126, the second driving component 126 is fixedly disposed on the connector 14, and the second driving component 126 is drivenly connected to the adhesive pressing mounting component 125.

[0084] The connector 14 is provided with a second guide rail 141. Specifically, one side of the connector 14 is slidably mounted on the first guide rail 131, while the other side is provided with a second guide rail 141 extending along the first direction X. The adhesive mounting component 125 is movably mounted on the second guide rail 141. In this way, the adhesive mounting component 125 can move along the first direction X, thereby driving the adhesive mounting component 122 to move along the first direction X on the first through hole 1211, thereby pressing and pasting the bent tape 3 onto the end face of the cylindrical battery 2.

[0085] The second driving component 126 can also be a driving component such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder; this application does not limit this. The second driving component 126 is fixedly disposed on the connecting component 14 and is drivenly connected to the pressure-adhesive mounting component 125. Specifically, the body of the second driving component 126 is fixedly disposed on the connecting component 14, while its output end is connected to the pressure-adhesive mounting component 125, thereby driving the pressure-adhesive mounting component 125 and the pressure-adhesive component 122 to move relative to the connecting component 14 along the first direction X.

[0086] like Figures 1 to 3 As shown in 9 to 11, in some embodiments, an elastic element 127 is provided between the second driving member 126 and the pressure-adhesive mounting member 125.

[0087] The elastic element 127 can be a spring or an elastic component made of elastic material such as rubber; this embodiment does not limit this. The elastic element 127 is disposed between the second driving member 126 and the adhesive mounting member 125. Specifically, one end of the elastic element 127 abuts against the output end of the second driving member 126, and the other end abuts against the adhesive mounting member 125. In this way, when the adhesive mounting member 122 moves along the first direction X and contacts the end face of the cylindrical battery 2, the elastic element 127 can be compressed to buffer the impact force between the adhesive mounting member 126 and the cylindrical battery 2, reducing the collision force on the cylindrical battery 2 and improving the production quality of the cylindrical battery 2.

[0088] like Figure 1 , 9 As shown in Figure 11, in some embodiments, the positioning component 11 includes a positioning member 111 and a pressing member 112. The positioning member 111 is disposed on one side of the folding member 121; the pressing member 112 is disposed at a distance from the positioning member 111, and the pressing member 112 is movable relative to the positioning member 111.

[0089] The positioning component 111 refers to a component that limits the cylindrical battery 2 to maintain a relatively definite position of the cylindrical battery 2 in the folding device 1. Specifically, the positioning component 111 can be a V-shaped positioning block or a semi-circular groove corresponding to the outer cylindrical surface of the cylindrical battery. This application embodiment does not limit this.

[0090] The pressing member 112 and the positioning member 111 are spaced apart. Specifically, the pressing member 112 is spaced apart on one side of the positioning member 111 along the third direction Z. The cylindrical battery 2 is clamped and released in the positioning assembly 11 by its movement along the third direction Z. The movable arrangement between the pressing member 111 and the positioning member 111 can be achieved by a guide rail slider mechanism or a lead screw mechanism. This embodiment of the application does not limit this.

[0091] By setting the positioning component 111 and the pressing component 112, when the pressing component 112 approaches the positioning component 111, the cylindrical battery 2 can be fixed in the positioning component 11, so that the tape 3 extending from the end face of the cylindrical battery 2 can smoothly enter the second through hole 1212, thereby realizing the folding and pressing of the cylindrical battery 2.

[0092] like Figure 1 , 9 As shown in Figure 11, in some embodiments, the positioning component 11 further includes a limiting member 113 disposed on the side of the positioning member 111 opposite to the folded adhesive member 121.

[0093] The limiting member 113 is disposed on the side of the positioning member 111 opposite to the folding member 121, that is, the folding member 121 and the limiting member 113 are respectively disposed on both sides of the positioning member 111 along the first direction X. When the folding member 121 approaches the cylindrical battery 2 on the positioning member 111, the limiting member can abut against the end of the cylindrical battery 2 away from the folding member 121, further restricting the movement of the cylindrical battery 2 along the first direction X, ensuring that the adhesive end face of the cylindrical battery 2 can smoothly enter the second through hole 1212, realizing the folding and pressing of the cylindrical battery 2.

[0094] like Figure 1 , 9 As shown in Figure 11, in some embodiments, the positioning component 11 further includes a positioning frame 114 and a third drive member 115, the third drive member 115 being disposed on the positioning frame 114 and drivenly connected to the limiting member 113.

[0095] The third driving component 115 can be a driving component such as an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and this application embodiment does not limit this. The third driving component 115 is disposed on the positioning frame 114 and is drivenly connected to the limiting component 113. Specifically, the body of the third driving component is disposed on the positioning frame 114, and its output end is connected to the limiting component 113, thereby driving the limiting component 113 to move along the first direction X to realize the limiting function of the cylindrical battery 2.

[0096] By setting the third driving component 115, the position of the limiting component 113 in the first direction X can be adjusted, thereby making it suitable for cylindrical batteries 2 of different lengths and improving the applicability of the folding device 1.

[0097] like Figure 1 , 9 As shown in Figure 11, in some embodiments, the pressing member 112 includes a pressing drive unit 1121, a pressing part 1122, and an elastic washer 1123. The pressing drive unit 1121 is fixedly mounted on the positioning frame 114, and the pressing part 1122 is drivenly connected to the pressing drive unit 1121; the elastic washer 1123 is disposed between the pressing drive unit 1121 and the pressing part 1122.

[0098] The pressing drive unit 1121 can be a driving component such as an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and this application embodiment does not limit this. The pressing drive unit 1121 is fixedly mounted on the positioning frame 114, and the pressing part 1122 is drivenly connected to the pressing drive unit 1121. Specifically, the body of the pressing drive unit 1121 is mounted on the positioning frame 114, and the output end of the pressing drive unit is connected to the pressing part 1122 to drive the pressing part 1122 to move relative to the positioning frame 114 in the third direction Z, thereby fixing the cylindrical battery 2 between the pressing part 1122 and the positioning member 111.

[0099] The elastic washer 1123 can be a spring or an elastic element made of elastic material such as rubber. The elastic washer 1123 is positioned between the pressing drive part 1121 and the pressing part 1122. When the pressing part 1122 contacts the cylindrical battery 2, the elastic washer 1123 can act as a buffer, reducing the impact force on the cylindrical battery 2, thereby improving the production quality of the cylindrical battery 2.

[0100] like Figures 9 to 11 As shown, this application also provides a glue-folding device, including a plurality of glue-folding devices 1, which are arranged at intervals.

[0101] Multiple adhesive bending devices 1 are arranged at intervals, specifically multiple adhesive bending devices 1 are arranged at intervals along the second direction Y, so that the adhesive bending equipment can simultaneously apply adhesive to the end faces of multiple cylindrical batteries 2, thereby improving the production efficiency of cylindrical batteries 2.

[0102] In some embodiments, the pressing drive unit 1121 includes a drive plate extending along the second direction Y, so that one pressing drive unit 1121 can simultaneously position multiple cylindrical batteries 2, saving resources while improving the production efficiency of cylindrical batteries 2.

[0103] Specifically, such as Figures 1 to 6 As shown, during the feeding process, the cylindrical battery 2 is fed into the positioning member 111, and the pressing drive unit 1121 drives the pressing part 1122 to move closer to the positioning member 111 along the third direction Z, thereby fixing the cylindrical battery 2 between the positioning member 111 and the pressing part 1122.

[0104] Subsequently, the first driving member 15 drives the connecting member 14 to move along the first direction X, causing the folding adhesive member 121 to gradually approach the cylindrical battery 2 positioned on the positioning assembly 11 along the first direction X. Then, the adhesive tape 3 extending from the end of the cylindrical battery 2 gradually enters the second through hole 1212 and, guided by the adhesive surface 1213, gradually bends and gathers inward. Finally, the second driving member 126 drives the pressing adhesive mounting member 125 and its pressing adhesive member 122 to move along the first direction X, thereby squeezing and pasting the bent and gathered adhesive tape 3 to the end of the cylindrical battery 2, realizing the folding and pressing adhesive functions of the cylindrical battery 2.

[0105] Finally, the first driving component 15 and the pressing driving part 1121 drive the adhesive pressing assembly 12 and the pressing part 1122 away from the cylindrical battery 2, so that the cylindrical battery 2 with end face adhesive is unloaded from the positioning assembly 11, and the cylindrical battery 2 to be adhesive is loaded.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
