[0067] To better understand the embodiments of this application, the following is combined with... Figures 1 to 14 The embodiments of this application will be described in detail.

[0068] like Figures 1 to 13 As shown, this application provides a battery cover closing device 1 for covering a cap 2 onto a housing 3. The battery cover closing device 1 includes a pressure head assembly 11, a lifting assembly 12, a turntable 13, and a guide assembly 14. The pressure head assembly 11 includes a holding member 111 and a first protrusion 112. The holding member 111 is disposed at one end of the pressure head assembly 11 along the vertical direction X and is used to hold the cap 2. The lifting assembly 12 is disposed corresponding to the pressure head assembly 11 along the vertical direction X. The lifting assembly 12 includes a limiting member 121 and a second protrusion 122. The limiting member 121 is disposed at one end of the lifting assembly 12 near the pressure head assembly 11 and is used to limit the housing 2. The pressure head assembly 11 and / or the lifting assembly 12 are movably disposed on the turntable 13 along the vertical direction X. The guide assembly 14 includes a first guide groove 141 and / or a second guide groove 142. The first guide groove 141 and the second guide groove 142 are respectively used to drive the first protrusion 112 and the second protrusion 122 to move along the vertical direction X.

[0069] During battery production, the cap 2 is placed on the casing 3 to ensure the battery's interior is isolated from the external environment, preventing electrolyte leakage and the entry of external contaminants, thus ensuring battery safety and performance. In this application, the battery can be a lithium-ion battery, lithium-sulfur battery, sodium-lithium-ion battery, sodium-ion battery, or magnesium-ion battery, etc., and this application embodiment does not limit this. The casing 3 can be cylindrical, flat, cuboid, or other shapes, etc., and this application embodiment also does not limit this.

[0070] The gripper 111 refers to a component used to grip and fix materials. Specifically, the gripper 111 can be a claw, which clamps and releases materials by opening and closing the claw; in addition, the gripper 111 can also be an adsorption component, which uses adsorption force to adsorb and fix materials.

[0071] The limiting member 121 refers to a component used to limit the housing 3. Specifically, the limiting member 121 can also be a gripper, suction member, or other holding member. In this case, the limiting member 121 and the holding member 111 can be the same type of holding mechanism or different types of holding mechanisms. This application embodiment does not impose any restrictions on this. In addition, the limiting member 121 can also be a limiting hole, which limits the housing 3 to the end of the lifting assembly 12 near the pressure head assembly 11.

[0072] The turntable 13 is a component used to support and fix the pressure head assembly 11 and the lifting assembly 12. The pressure head assembly 11 and / or the lifting assembly 12 are movably disposed on the turntable 13 in the vertical direction X. That is, in some embodiments, either the pressure head assembly 11 or the lifting assembly 12 is movably disposed on the turntable 13 in the vertical direction X, and the cap 2 and the housing 3 gradually approach each other until they are closed together by the movement of one of them in the vertical direction X; while in other embodiments, both the pressure head assembly 11 and the lifting assembly 12 are movably disposed on the turntable 13 in the vertical direction X, and the cap 2 and the housing 3 are closed by the joint movement of both. By movably disposing the pressure head assembly 11 and / or the lifting assembly 12 in the vertical direction X on the turntable 13, when the turntable 13 rotates, the pressure head assembly 11 and the lifting assembly move closer or further apart in the vertical direction X under the guidance of the guide assembly 14, thereby closing the cap 2 onto the housing 3.

[0073] It should be noted that the relative movement between the pressure head assembly 11 and the turntable 13 can be achieved through a guide rail slider mechanism, a ball screw mechanism, or a gear and rack mechanism, etc., and this application embodiment does not impose any limitation on this. Similarly, the relative movement between the lifting assembly 12 and the turntable 13 can also be achieved through a guide rail slider mechanism, a ball screw mechanism, or a gear and rack mechanism, etc., and this application embodiment also does not impose any limitation on this.

[0074] The guide component 14 includes a first guide groove 141 and / or a second guide groove 142. That is, in some embodiments, the guide component 14 includes one of the first guide groove 141 and the second guide groove 142; while in other embodiments, the guide component 14 includes both the first guide groove 141 and the second guide groove 142.

[0075] In some embodiments, the first guide groove 141 can be a closed-loop guide groove formed end-to-end on the guide assembly 14. In this way, when the first protrusion 112 moves in the first guide groove 141, it can circulate along the closed-loop path of the first guide groove 141 and return to the starting position, thereby achieving continuous reciprocating motion. That is, driven by the first guide groove 141, the pressure head assembly 11 can reciprocate along the vertical direction X, allowing the cap 2 and housing 3 to close continuously, improving the closing efficiency of the battery closing device 1. Similarly, the second guide groove 142 can also be a closed-loop guide groove formed end-to-end on the guide assembly 14, which can drive the lifting assembly 12 to reciprocate along the vertical direction X.

[0076] By setting the first guide groove 141 and / or the second guide groove 142, the first protrusion 112 and the second protrusion 122 are driven to move continuously and reciprocally in the vertical direction, thereby causing the cap and the housing, which are clamped on the holding member 111 and the limiting member 121, to gradually move closer in the vertical direction X until the cap 2 is closed on the housing 3. In addition, since the first guide groove 141 and the second guide groove 142 are closed-loop guide grooves connected end to end, after the cap 2 is closed on the housing 3, the pressure head assembly 11 and the lifting assembly 12 can automatically return to the initial position, preparing for the next capping process. This makes the cap 2 and housing 3 closing action continuous, improving the capping efficiency and the battery production efficiency.

[0077] like Figure 1 , 4 As shown in Figures 7 to 13, in some embodiments, the battery cover closing device 1 further includes a positioning member 15, which is disposed vertically between the pressure head assembly 11 and the lifting assembly 12, and the positioning member 15 is provided with a positioning hole 151 extending in the vertical direction X.

[0078] The positioning hole 151 extends vertically and its shape corresponds to the shape of the cap 2 and the housing 3.

[0079] By setting the positioning element 15, when the cap 2 and the housing 3 approach each other along the vertical direction X, the cap 2 and the housing 3 are respectively inserted into the positioning hole 151 along the vertical direction X, so that the cap 2 and the housing 3 are positioned at both ends of the positioning hole 151 along the vertical direction X, which can ensure the concentricity between the cap 2 and the housing 3, so that the cap 2 can accurately cover the housing 3.

[0080] In some embodiments, the positioning element 15 is a three-jaw chuck.

[0081] By setting the positioning component 15 as a three-jaw chuck, on the one hand, the three symmetrically distributed jaws of the three-jaw chuck can apply force evenly to achieve precise positioning and stable clamping of the cap 2 and the housing 3, avoiding displacement or tilting of the two during the closing process; on the other hand, the jaws of the three-jaw chuck can be adjusted according to the cap 2 and housing 3 of different sizes to meet the production needs of various specifications of batteries.

[0082] like Figure 4 As shown in 6 to 9 and 13, in some embodiments, the battery cover device 1 further includes a housing positioning assembly 16 disposed in the vertical direction X between the lifting assembly 12 and the positioning member 15.

[0083] The housing positioning assembly 16 is disposed between the lifting assembly 12 and the positioning member 15. When the housing 3 moves in the vertical direction X, the housing positioning assembly 16 can position the housing 3 to ensure that it is accurately inserted into the positioning hole 151 in the vertical direction X. By setting the housing positioning assembly 16 to position the housing 3, it is possible to effectively prevent the housing 3 from shifting or tilting during movement, thereby improving the sealing accuracy between the cap 2 and the housing 3, and further improving the quality and efficiency of battery production.

[0084] like Figure 6 and Figure 9 As shown, in some embodiments, the housing positioning assembly 16 includes a positioning part 161, which is movably disposed on the turntable 13 in the vertical direction X, so that the positioning part 161 can move together with the housing 3 in the vertical direction X.

[0085] The positioning part 161 is movably disposed on the turntable 13 along the vertical direction X. Specifically, the movable connection between the positioning part 161 and the turntable 13 can be achieved by a guide rail slider mechanism, or by a lead screw mechanism or a gear rack mechanism. This application embodiment does not limit this.

[0086] By configuring the positioning part 161 as a structure that can move along the vertical direction X, when the housing 3 moves along the vertical direction X, the positioning part 161 can move along the vertical direction X together, so that the positioning part 161 and the housing 3 remain relatively stationary. While ensuring the positioning accuracy of the housing 3, it also avoids friction between the positioning part 161 and the housing 3 due to relative movement, thereby effectively preventing the surface of the housing 3 from being scratched and further improving the production quality of the battery.

[0087] like Figure 6 and Figure 9 As shown, in some embodiments, the housing positioning assembly 16 further includes a magnetic part 162 disposed on the positioning part 161 for adsorbing and fixing the housing 3.

[0088] The magnetic part 162 can be a permanent magnet or an electromagnet, and the embodiments of this application do not limit it.

[0089] By setting up the magnetic part 162, the housing 3 is fixed by magnetic attraction, which can ensure that the housing 3 is accurately positioned on the housing positioning component 16. This not only improves the positioning accuracy of the housing 3, but also simplifies the fixing operation and avoids damage to the surface of the housing 3 caused by mechanical clamping, thereby further improving the production efficiency and product quality of the battery.

[0090] like Figure 6 and Figure 9 As shown, in some embodiments, the housing positioning assembly 16 further includes a positioning roller 163, which is rotatably disposed on the positioning part 161, so that the positioning roller 163 makes rolling contact with the housing 3.

[0091] By rotatably setting the positioning roller 163 on the positioning part 161, when the positioning part 161 abuts against the positioning member 15 and cannot continue to move in the vertical direction X, the positioning roller 163 can convert the sliding friction between the housing 3 and the housing positioning assembly 16 into rolling friction, effectively reducing the frictional resistance between the two and avoiding scratching the surface of the housing 3, thereby improving the battery production quality.

[0092] like Figure 4 and Figure 6 As shown, in some embodiments, the housing positioning assembly 16 further includes a spring 164, one end of which is connected to the positioning part 161, and the other end is connected to the turntable 13. By setting the spring 164, after the cap 2 and housing 3 are closed, the positioning part 161 can return to its initial position by the elastic force provided by the spring 164, preparing for the next closing process.

[0093] like Figure 1 , 4 As shown in 7, 8, 12 and 13, in some embodiments, the second protrusion 122 is a roller disposed on the end of the lifting assembly 12 away from the limiting member 121, and the second guide groove 142 is an end face disposed along the vertical direction X toward the roller. When the roller moves along the end face, it drives the lifting assembly 12 to approach the pressure head assembly 11 along the vertical direction X.

[0094] The change in distance of the end face along the vertical direction X can drive the second protrusion 122 to move along the vertical direction X. In addition, by setting the second protrusion 122 as a roller at one end of the lifting assembly 12 and setting the second guide groove 142 as the end face facing the vertical direction X, it can be ensured that the driving force between the end face and the second protrusion 122 coincides with the extension direction of the housing 3, providing the housing 3 with the maximum driving force and completing the closing process of the cap 2 and the housing 3 more efficiently.

[0095] like Figure 7 , 8As shown in 12 and 13, in some embodiments, the lifting assembly 12 further includes a third protrusion 123, and the guide assembly 14 includes a third guide groove (not shown in the figure). The third protrusion 123 moves along the third guide groove to drive the lifting assembly 12 away from the pressure head assembly 11 in the vertical direction X.

[0096] By setting the third protrusion 123 and the third guide groove, after the cap 2 and the housing 2 complete the capping process, the lifting component 12 can be driven away from the positioning component 15, so as to facilitate the unloading of the housing 2 and the cap 2 after the capping process is completed, and at the same time provide sufficient space for the subsequent loading of the housing 3, thereby realizing the continuity and efficiency of the production process and further improving the overall efficiency of battery production.

[0097] like Figure 8 , 9 and Figure 13 As shown, in some embodiments, the lifting assembly 12 further includes a lifting body portion 124 and an ejection portion 125. The lifting body portion 124 is a hollow structure, and the limiting member 121 is a holding hole provided at one end of the lifting body portion; the ejection portion 125 is movably disposed within the lifting body portion 124 along the vertical direction X.

[0098] The limiting member 121 is a holding hole located at one end of the lifting body section, used to receive the housing 3 and ensure the accurate positioning of the housing 3. In addition, the lifting body section 124 is configured as a hollow structure, and the ejector section 125 can be disposed within the hollow structure and can move vertically in the X direction within the hollow structure. By moving the ejector section 124 vertically in the X direction, the housing 3 can be ejected from the holding hole of the lifting assembly 12, thereby achieving rapid and precise unloading of the housing 3.

[0099] like Figure 8 , 9 and Figure 13 As shown, in some embodiments, the lifting assembly 12 further includes a fourth protrusion 126 connected to the ejector portion 125, and the guide assembly 14 includes a fourth guide groove (not shown in the figure). The fourth protrusion 126 moves along the fourth guide groove to drive the ejector portion 125 to move in the vertical direction X.

[0100] The connection between the ejector portion 125 and the fourth protrusion 126 can be a detachable connection such as bolt connection or snap-fit, or a non-detachable connection such as welding or bonding. This application embodiment does not limit this. By providing the fourth protrusion 126 and the fourth guide groove, the ejector portion 125 can be driven to move vertically by X to complete the unloading of the housing 3 from the holding hole.

[0101] like Figure 8 , 9 and Figure 11As shown, in some embodiments, the pressure head assembly 11 includes a pressure head body 113 and a pressure head 114. The pressure head 114 is disposed along the vertical direction X at one end of the pressure head body 113 near the lifting assembly 12. The pressure head 114 and the pressure head body 113 are hollow structures, and the holding member 111 is movably disposed within the pressure head body 113 and the pressure head 114 along the vertical direction X.

[0102] The pressure head 114 is located at one end of the pressure head body 113 near the lifting assembly 12. When the pressure head assembly 11 approaches the lifting assembly in the vertical direction X, the pressure head 114 presses the cap 2 onto the housing, ensuring that the cap 2 and the housing 3 are firmly closed.

[0103] By making the pressure head 114 and the pressure head body 113 hollow, when the holding member 111 puts the cap 2 into the positioning hole 151, the holding member 111 can retract into the hollow structure of the pressure head 114 and the pressure head body 113 in the vertical direction X, ensuring that the pressure head 114 can effectively abut against the cap 2, and improving the firmness of the cap 2 and the housing 3.

[0104] like Figure 3 As shown, in some embodiments, the pressure head assembly 11 further includes a fifth protrusion 115 connected to the holding member 111, and the guide assembly 14 includes a fifth guide groove 143. The fifth protrusion 115 moves along the fifth guide groove 143 to drive the holding member 111 to move in the vertical direction X.

[0105] Similarly, the connection between the fifth protrusion 115 and the holding member 111 can be a detachable connection such as bolt connection or snap-fit, or a non-detachable connection such as welding or bonding. This application embodiment does not limit this.

[0106] By setting the fifth protrusion 115 and the fifth guide groove 143, the holding member 111 can be driven to move in the vertical direction X, so that the holding member 111 can extend from the pressing head 114 and the pressing head body 113 to complete the loading of the cap 2, and can also retract into the pressing head 114 and the pressing head body 113 to ensure effective contact between the pressing head 114 and the cap 2.

[0107] like Figure 8 and Figure 11 As shown, the pressure head assembly 11 also includes a connector 116, an elastic element 117, and a pressure sensor 118. The connector 116 is movably disposed along the vertical direction X at one end of the pressure head body 113 opposite to the pressure head 114, and a first protrusion 112 is disposed on the connector 116. The elastic element 117 is disposed along the vertical direction X between the connector 116 and the pressure head body 113. The pressure sensor 118 is disposed between the elastic element 117 and the pressure head body 113 for measuring the pressure of the pressure head body 113.

[0108] The elastic element 117 can be a component made of elastic material such as rubber, or it can be a spring. By setting the elastic element 117, on the one hand, the elastic element 117 can be compressed to transmit the pressure received by the pressure head assembly 11 to the pressure sensor 118, which facilitates the measurement of the pressure of the pressure head 114; on the other hand, it can also avoid rigid contact between the connector 116, the pressure head body 113 and the pressure sensor 118, which would damage the pressure sensor 118.

[0109] By setting the elastic element 117 and the pressure sensor 118, the first protrusion 112 drives the pressure head assembly 11 to gradually approach the lifting assembly 12, so that when the pressure head 114 abuts against the cap 2, it can drive the pressure head body 113 and the connecting piece 116 to compress the elastic element 117 and transmit the pressure to the pressure sensor 118, which facilitates the measurement of the pressure received by the pressure head 114 and prevents excessive pressure from damaging the cap 2 or the housing 3.

[0110] like Figure 7 , 8 As shown in Figures 10 and 11, in some embodiments, the pressure head assembly 11 further includes a pressure head roller 11 disposed at one end of the pressure head assembly 11 away from the holding member 111, and the guide assembly 14 includes a guide surface (not shown in the figure) disposed along the vertical direction X toward the pressure head roller 119.

[0111] By setting the pressure head roller 119, on the one hand, the movement freedom of the pressure head assembly 11 in the vertical direction X can be restricted, thereby improving the stability of the pressure head assembly 11; on the other hand, when the first cam 112 moves along the first closed groove 141, the friction between the end of the pressure head assembly 11 away from the holding member 111 and the guide assembly 14 can be converted into rolling friction, thereby reducing the wear of the pressure head assembly 11.

[0112] like Figure 2 As shown, in some embodiments, the guide assembly 14 further includes a first cam 144 and a second cam 145, which are spaced apart along the vertical direction X to form a first guide groove 141 between them. The battery cover closing device 1 also includes a monitoring assembly 17, which is disposed along the vertical direction X on the side of the pressure head assembly 11 opposite to the lifting assembly 12. The monitoring assembly 17 includes a monitoring mounting member 171, a proximity sensor 172, a monitoring element 173, and an alarm (not shown in the figure). Specifically, the first cam 144 is movably disposed on the monitoring mounting member 171 along the vertical direction X; the proximity sensor 172 is disposed on the first cam 144; the monitoring element 173 is disposed corresponding to the proximity sensor 172 along the vertical direction X; when the distance between the proximity sensor 172 and the monitoring element 173 along the vertical direction X is less than a preset value, the alarm sounds.

[0113] The movable arrangement between the first cam 144 and the monitoring mounting component 171 can be achieved through a guide rail slider mechanism, or through a lead screw mechanism or a gear and rack mechanism. This application embodiment does not limit this.

[0114] By setting up the monitoring component 17, when the cap 2, pressure head 114, or positioning hole 151 is misaligned, resulting in excessive frictional resistance between the cap 2 or pressure head 114 and the positioning hole 151, the squeezing force between the first protrusion 112 and the first cam 144 will be excessive, driving the first cam 144 to move in a direction away from the vertical direction X. This, in turn, drives the monitoring component 173 to gradually approach the proximity sensor 172, ultimately causing the distance between the two along the vertical direction X to be less than a preset value, triggering an alarm and alerting the operator that the equipment is malfunctioning. In this way, the cap 2 or pressure head 114 can be prevented from being forcibly inserted into the positioning hole 151 and damaging the battery cap device 1.

[0115] like Figure 14 As shown, this application also provides a battery production apparatus, including a battery capping device 1, a feeding device 4, and a discharging device 5. The feeding device 4 is disposed on one side of the battery capping device 1 and includes a first feeding component 41 and a second feeding component 42, respectively used to feed the cap 2 and the housing 3 to the battery capping device 1. The discharging device 5 is disposed on one side of the battery capping device 1 and is used to unload the cap 2 and the housing 3 after they are capped.

[0116] The feeding device 4 is located on one side of the battery cover device 1. Specifically, the feeding device 4 is located on one side of the turntable 13. When the turntable 13 rotates, different pressure head assemblies 11 located on the outer periphery of the turntable 13 can be sequentially transported to the position corresponding to the feeding device 4 to complete the feeding of the cap 2 and the shell 3 in sequence.

[0117] The feeding device 4 includes a first feeding component 41 and a second feeding component 42, which are spaced apart on the outer side of the turntable 13. They respectively feed the cap 2 and the housing 3. In this way, the feeding process of the cap 2 and the housing 3 can be set at different positions on the outer periphery of the turntable 13, which can prevent interference between the first feeding component 41 and the second feeding component 42.

[0118] Specifically, such as Figure 14As shown, the first feeding assembly 41 includes a first feeding disk 411 rotatable about its own axis and a plurality of first feeding positions 412 spaced apart on the outer periphery of the first feeding disk 411, with the cap 2 accommodated in the first feeding position 412. Furthermore, the first feeding positions 412 are correspondingly arranged with the holding member 111. Therefore, when the first feeding disk 411 rotates, the cap 3 on the first feeding position 412 can be sequentially transferred to the holding member 111 in the battery capping device 1.

[0119] Similarly, the second feeding assembly 42 includes a second feeding tray 421 rotatable about its own axis and a plurality of second feeding positions 422 spaced apart on the outer periphery of the second feeding tray 421, with the housing 3 housed in the second feeding position 422. Furthermore, the second feeding positions 412 are correspondingly arranged with the limiting member 121. Therefore, when the second feeding tray 421 rotates, the housing 3 on the second feeding position 422 can be sequentially transferred to the limiting member 121 in the battery closing device 1.

[0120] like Figure 14 As shown, the unloading device 5 is located on the outside of the turntable 13 and is used to remove the cap 2 and the housing 3 after they have been closed from the battery closing device 1. The specific structure of the unloading device 5 is similar to that of the first loading assembly 41 and the second loading assembly 42, and will not be described in detail here.

[0121] In some embodiments, the battery production equipment further includes a welding device (not shown in the figure) for welding the cap 2 and the housing 3 together after the cap is closed. The welding device is located downstream of the battery capping device 1, that is, the cap 2 and the housing 3 first pass through the battery capping device 1, and the capping process of the cap 2 and the housing 3 is completed on it before reaching the welding device, and finally the cap 2 and the housing 3 are welded together.

[0122] Specifically, such as Figures 1 to 14 As shown, during loading, the cap 2 and the housing 3 are respectively loaded into the holding member 111 and the limiting member 121, and the cap 2 and the housing 3 are respectively inserted into the two ends of the positioning hole 151 along the vertical direction X to ensure their concentricity. Subsequently, the fifth protrusion 115, guided by the fifth guide groove 143, drives the holding member 111 back into the pressing head 114. At the same time, the first protrusion 112 and the second protrusion 122 respectively drive the pressing head 114 and the lifting body part 124 to move closer to each other, thus covering the cap 2 onto the housing 3. Finally, the first protrusion 112 and the third protrusion 123 drive the pressing head 114 and the lifting body part 124 away from each other to complete the unloading of the cap 2 and the housing 3 after the covering process is completed.

[0123] 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.

[0124] 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.
