Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and more specifically, to a gripper quick-release mechanism and a sealing device. Background Technology

[0002] During the battery manufacturing process, after the battery cell casing and cover are closed, a stamping process is required to further press the two together. The cover closes the opening of the casing and encloses the electrode assembly inside the casing.

[0003] To improve the sealing accuracy of individual battery cells, a gripper is used to circumferentially clamp the housing, and then a pressure head is used to press down the cover. However, since the gripper is installed on the turntable using threaded parts, it needs to be repeatedly installed and removed during maintenance. This not only easily leads to stripping of the threaded holes, but also makes the installation and removal process time-consuming and laborious, increasing the difficulty of maintenance. Utility Model Content

[0004] Therefore, this application proposes a quick-release gripper mechanism and a sealing device, wherein the gripper is easy to install and remove, thereby facilitating inspection and maintenance.

[0005] The quick-release mechanism for the gripper according to a first aspect of this application includes: a mounting plate; a gripper housing, the outer peripheral surface of which has a first protrusion, the first protrusion having a first abutting side and a locking side on its two sides in the circumferential direction of the gripper housing, respectively; a first limiting member disposed on the mounting plate; and an unlocking button disposed on the first limiting member or the mounting plate. When the gripper housing is installed, the first abutting side of the first protrusion abuts against the first limiting member, and the unlocking button is configured to abut against the locking side of the first protrusion to circumferentially fix the gripper housing to the mounting plate. When the gripper housing is disassembled, the unlocking button is configured to release the locking side of the first protrusion by pressing, allowing the gripper housing to circumferentially rotate relative to the mounting plate.

[0006] Optionally, the unlock button includes a blocking member, an elastic member, and a button. The elastic member is disposed between the mounting plate and the blocking member. The bottom surface of the button abuts against the top surface of the blocking member. The blocking member is used to abut against the locking side of the first protrusion.

[0007] Optionally, the first limiting member is provided with a mounting hole, and the button is slidably mounted in the mounting hole.

[0008] Optionally, the first protrusion has an unlocking gap with the mounting plate, and the blocking member is configured to move into the unlocking gap to release the locking side of the first protrusion.

[0009] Optionally, the first limiting member includes a first limiting surface and a first guiding surface, the first guiding surface being configured to slide in cooperation with the first protrusion to guide the first abutting side toward the first limiting surface.

[0010] Optionally, the outer peripheral surface of the gripper housing further includes a second protrusion, the second protrusion having a second abutting side in the circumferential direction of the gripper housing, the second abutting side being disposed on the same side as the first abutting side of the first protrusion in the circumferential direction of the gripper housing, and the gripper quick-release mechanism further includes: a second limiting member disposed on the mounting plate; when the gripper housing is installed, the second abutting side of the second protrusion abuts against the second limiting member.

[0011] Optionally, the second limiting member includes a second limiting surface and a second guiding surface, the second guiding surface being configured to slide in cooperation with the second protrusion to guide the second abutting side toward the second limiting surface.

[0012] Optionally, the outer peripheral surface of the gripper housing is further provided with a third protrusion, the third protrusion including a third abutting side in the circumferential direction of the gripper housing, the third abutting side and the first abutting side of the first protrusion being disposed on the same side in the circumferential direction of the gripper housing;

[0013] When multiple quick-release gripper mechanisms are spaced apart on the same mounting plate, a first limiting member is disposed between two adjacent gripper housings. The first limiting member abuts against the first abutting side of the first protrusion of one of the gripper housings on one side in the circumferential direction, and abuts against the third abutting side of the third protrusion of the adjacent gripper housing on the other side.

[0014] Optionally, the first limiting member further includes a top side limiting portion, and when the first abutting side of the first protrusion abuts against the first limiting member, the first protrusion is located between the mounting plate and the top side limiting portion in the thickness direction of the mounting plate.

[0015] The sealing device according to the second aspect of this application includes the quick-release claw mechanism described in the first aspect of this application, wherein a plurality of the quick-release claw mechanisms are spaced apart on the same mounting plate.

[0016] Compared with existing technologies, this solution has the following advantages:

[0017] The quick-release mechanism for grippers in this embodiment has a first protrusion on the outer circumferential surface of the gripper housing, and a first limiting member on the mounting plate. The gripper housing rotates clockwise until the first abutting side of the first protrusion abuts against the first limiting member, and the unlock button abuts against the locking side of the first protrusion to prevent the gripper housing from rotating relative to the mounting plate in the circumferential direction. During disassembly, pressing the unlock button releases the abutment relationship with the locking side of the first protrusion, allowing the gripper housing to rotate counterclockwise, enabling simple and quick disassembly of the gripper housing from the mounting plate. This quick-release mechanism for grippers is used in assembling gripper assemblies, which not only facilitates inspection and maintenance but also maintains good reliability and a long service life even after repeated assembly and disassembly.

[0018] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] like Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the sealing device 200 of some embodiments of this application includes a plurality of quick-release gripper mechanisms 100, which are spaced apart on the same mounting plate 110.

[0033] Specifically, the sealing device 200 is a turntable structure, and the sealing device 200 includes a rotation drive module 210, a pressing mechanism 220, a gripper mechanism 230 and a lifting mechanism 240.

[0034] Mounting plate 110 has a disc structure, with its central axis being a second axis Q, which is parallel to direction Z. Multiple quick-release gripper mechanisms 100 are circumferentially spaced around the second axis Q on the mounting surface 111 of mounting plate 110. A pressing mechanism 220 is located above the quick-release gripper mechanisms 100, and a gripper mechanism 230 is located below them. A lifting mechanism 240 is located below the gripper mechanism 230, which is used to hold the battery. The pressing mechanism 220, quick-release gripper mechanisms 100, gripper mechanism 230, and lifting mechanism 240 constitute a sealing module 250. A rotation drive module 210 drives multiple sealing modules 250 to rotate around the second axis Q. When a sealing module 250 reaches its corresponding sealing position, the lifting mechanism 240 pushes the battery upwards into the gripper assembly 160, which circumferentially grips the battery. The pressing mechanism 220 then seals the battery.

[0035] like Figure 2 , Figure 3 and Figure 6 As shown, the quick-release mechanism 100 of the gripper in some embodiments of this application includes a mounting plate 110, a gripper housing 120, a first limiting member 130, and an unlocking button 140. The outer peripheral surface 124 of the gripper housing 120 is provided with a first protrusion 121, with a first abutting side 1211 and a locking side 1212 on either side of the first protrusion 121 in the circumferential direction of the gripper housing 120; the first limiting member 130 is disposed on the mounting plate 110; and the unlocking button 140 is disposed on either the first limiting member 130 or the mounting plate 110. When the gripper housing 120 is installed, the first abutting side 1211 of the first protrusion 121 abuts against the first limiting member 130, and the unlocking button 140 is configured to abut against the locking side 1212 of the first protrusion 121 to circumferentially fix the gripper housing 120 to the mounting plate 110; when the gripper housing 120 is removed, the unlocking button 140 is configured to release the locking side 1212 of the first protrusion 121 by pressing, so as to allow the gripper housing 120 to rotate circumferentially relative to the mounting plate 110.

[0036] The thickness direction of the mounting plate 110 is direction Z, and the side of the mounting plate 110 along direction Z is the mounting surface 111; the claw housing 120 has a cylindrical structure, and the claw assembly 160 is installed inside the claw housing 120 (please refer to...). Figure 9 The central axis of the gripper housing 120 is the first axis P, which is parallel to the direction Z. The outer peripheral surface 124 of the gripper housing 120 extends around the first axis P. The side of the first protrusion 121 along the clockwise direction N1 is the first abutting side 1211, and the side along the counterclockwise direction N2 is the locking side 1212.

[0037] The quick-release gripper mechanism 100 is applied to the sealing device 200. The gripper assembly 160 circumferentially grips the battery casing, and the pressing mechanism 220 presses down on the battery cover from above to complete the sealing action of the battery. In other embodiments, the quick-release gripper mechanism 100 can also be applied to other occasions.

[0038] like Figure 2 and Figure 6 As shown, the quick-release mechanism 100 of this application has a first protrusion 121 on the outer peripheral surface 124 of the claw housing 120, and a first limiting member 130 on the mounting plate 110. The claw housing 120 rotates clockwise in the direction N1 until the first abutting side 1211 of the first protrusion 121 abuts against the first limiting member 130, and the unlocking button 140 abuts against the locking side 1212 of the first protrusion 121 to prevent the claw housing 120 from rotating relative to the mounting plate 110 in the circumferential direction. During disassembly, pressing the unlocking button 140 releases the abutting relationship with the locking side 1212 of the first protrusion 121, allowing the claw housing 120 to rotate counterclockwise in the direction N2, thus enabling the claw housing 120 to be easily and quickly disassembled from the mounting plate 110. This quick-release mechanism 100 is used to assemble the claw assembly 160, which not only facilitates inspection and maintenance, but also maintains good reliability and has a long service life after repeated assembly and disassembly.

[0039] like Figure 3 As shown, in some embodiments of this application, the unlock button 140 includes a blocking member 141, an elastic member 142, and a button 143. The elastic member 142 is disposed between the mounting plate 110 and the blocking member 141. The bottom surface of the button 143 abuts against the top surface of the blocking member 141. The blocking member 141 is used to abut against the locking side 1212 of the first protrusion 121.

[0040] The bottom surface of button 143 refers to the surface of button 143 along the Z direction that is close to the mounting surface 111 of mounting plate 110, and the top surface of blocking member 141 refers to the surface of blocking member 141 along the Z direction that is away from mounting surface 111. The bottom surface of button 143 and the top surface of blocking member 141 abutting each other means that their projections on the XY plane coincide.

[0041] The blocking member 141 has a groove inside, and a spring seat is provided on the mounting surface 111 of the mounting plate 110. The elastic member 142 is a straight spring extending along the Z direction. One end of the elastic member 142 is fixed to the spring seat, and the other end extends into the groove of the blocking member 141, elastically supporting the blocking member 141 from inside. The button 143 is positioned further away from the claw housing 120 relative to the blocking member 141, so as not to occupy the space required for the circumferential rotation of the claw housing 120.

[0042] This configuration simplifies the construction of each component of the unlock button 140, and pressing the button 143 separates the blocking member 141 from the first protrusion 121 in the Z direction.

[0043] In other embodiments, the blocking member 141 and the button 143 may also be integrated into a single component; the elastic member 142 may also extend in other directions, the blocking member 141 may be displaced in other directions to release the first protrusion 121, and the blocking member 141 may also move away from the first protrusion 121 radially along the gripper housing 120, allowing the gripper housing 120 to rotate in a counterclockwise direction N2.

[0044] Furthermore, the first limiting member 130 is provided with a mounting hole 131, and the button 143 is slidably mounted in the mounting hole 131.

[0045] In other words, the projection of button 143 on the XY plane falls within the projection range of the first limiting member 130. The mounting hole 131 penetrates the first limiting member 130 along the Z direction. Button 143 presses against the blocking member 141 along the Z direction, or is reset and lifted along the Z direction under the elastic force of the elastic member 142. The first limiting member 130 includes a top side limiting part 135, which has a gap with the mounting surface 111. The bottom edge of button 143 may be provided with an anti-detachment boss, which abuts against the bottom surface of the top side limiting part 135 to prevent button 143 from detaching from the first limiting member 130.

[0046] This arrangement reduces the shared area of ​​the first limiting member 130 and the unlock button 140 on the mounting plate 110, improving the compactness of the layout. It also limits the direction of movement of the button 143 when subjected to external force, thus improving the reliability of the pressing action.

[0047] Preferably, the blocking member 141 is at least partially disposed on the lower side of the top limiting part 135, which can further reduce the common area occupied by the first limiting member 130 and the unlocking button 140 on the mounting plate 110.

[0048] In other embodiments, the unlock button 140 can be set independently relative to the first limiting member 130. The unlock button 140 is fixed to the mounting plate 110 and does not coincide with the projection of the first limiting member 130 on the XY plane.

[0049] like Figure 2 As shown, in some embodiments of this application, the first protrusion 121 has an unlocking gap 132 between it and the mounting plate 110, and the blocking member 141 is configured to move to the unlocking gap 132 to release the locking side 1212 of the first protrusion 121.

[0050] When the bottom surface of the gripper housing 120 is in contact with the mounting surface 111 of the mounting plate 110 along the Z direction, there is an unlocking gap 132 between the bottom surface of the first protrusion 121 and the mounting surface 111. The blocking member 141 switches between a locked position and an unlocked position. When the blocking member 141 is in the locked position, the blocking member 141 at least partially abuts against the first protrusion 121 in the Z direction to prevent the gripper housing 120 from rotating in the counterclockwise direction N2. When the blocking member 141 is pressed and reaches the unlocked position, the blocking member 141 is in the unlocking gap 132 in the Z direction, avoiding the movement trajectory of the first protrusion 121 and allowing the first protrusion 121 and the gripper housing 120 to rotate in the counterclockwise direction N2.

[0051] This configuration allows space for the movement of the blocking element 141 and simplifies the construction of the mounting plate 110, enabling the unlock button 140 to function normally with a simple design.

[0052] In other embodiments, the unlocking gap 132 may not be provided, and a relief groove may be formed in the mounting plate 110 to ensure that the blocking member 141 reaches the unlocking position after being pressed.

[0053] like Figure 6 As shown, in some embodiments of this application, the first limiting member 130 includes a first limiting surface 133 and a first guiding surface 134. The first guiding surface 134 is configured to slide in cooperation with the first protrusion 121 to guide the first abutting side 1211 to approach the first limiting surface 133.

[0054] The first limiting surface 133 and the first guiding surface 134 are both located on the side of the first limiting member 130 facing the claw housing 120. The first limiting surface 133 and the first guiding surface 134 are arranged approximately perpendicularly to each other. One end of the first guiding surface 134 is connected to the first limiting surface 133 along the periphery of the claw housing 120, and the other end gradually moves away from the claw housing 120 in a direction away from the first limiting surface 133.

[0055] By setting the first guide surface 134, the position of the gripper housing 120 can be assisted in correcting during the clockwise rotation of the gripper housing 120 in the direction N1, and the first abutting side 1211 of the first protrusion 121 can be guided to abut against the first limiting surface 133.

[0056] In other embodiments, the first guide surface 134 may be omitted to simplify the construction of the first limiting member 130.

[0057] like Figure 6As shown, in some embodiments of this application, the outer peripheral surface 124 of the gripper housing 120 further includes a second protrusion 122. The second protrusion 122 includes a second abutting side 1221 in the circumferential direction of the gripper housing 120. The second abutting side 1221 and the first abutting side 1211 of the first protrusion 121 are disposed on the same side in the circumferential direction of the gripper housing 120. The gripper quick-release mechanism 100 also includes a second limiting member 150 disposed on the mounting plate 110; when the gripper housing 120 is installed, the second abutting side 1221 of the second protrusion 122 abuts against the second limiting member 150.

[0058] The first abutting side 1211 is disposed on one side of the first protrusion 121 along the clockwise direction N1, and the second abutting side 1221 is disposed on one side of the second protrusion 122 along the clockwise direction N1. The first protrusion 121 and the second protrusion 122 are spaced apart around the first axis P on the outer peripheral surface 124 of the gripper housing 120. The first limiting member 130 and the second limiting member 150 are spaced apart circumferentially around the gripper housing 120. When the first protrusion 121 abuts against the first limiting member 130, the second protrusion 122 also abuts against the second limiting member 150.

[0059] This configuration allows for multi-point circumferential fixation of the gripper housing 120, improving the uniformity of force distribution on the gripper housing 120.

[0060] In some embodiments of this application, one second protrusion 122 is provided; in other embodiments, two, three, etc., the second protrusion 122 may be provided, and the multiple second protrusions 122 are circumferentially spaced from the first protrusion 121 on the outer peripheral surface 124 of the claw housing 120.

[0061] In some embodiments of this application, the first limiting member 130 and the second limiting member 150 are both fixed to the mounting plate 110 by threaded parts; in other embodiments, the above-mentioned components can also be fixed to the mounting plate 110 by snap-fit ​​or riveting, or formed integrally on the mounting plate 110.

[0062] like Figure 6 As shown, in some embodiments of this application, the second limiting member 150 includes a second limiting surface 151 and a second guiding surface 152. The second guiding surface 152 is configured to slide in cooperation with the second protrusion 122 to guide the second abutting side 1221 toward the second limiting surface 151.

[0063] The second limiting surface 151 and the second guiding surface 152 are both located on the side of the second limiting member 150 facing the claw housing 120. The second limiting surface 151 and the second guiding surface 152 are arranged approximately perpendicularly. One end of the second guiding surface 152 is connected to the second limiting surface 151 along the periphery of the claw housing 120, and the other end gradually moves away from the claw housing 120 in a direction away from the second limiting surface 151.

[0064] By setting the second guide surface 152, the position of the gripper housing 120 can be assisted in correcting during the clockwise rotation of the gripper housing 120 in the direction N1, and the second abutting side 1221 of the second protrusion 122 can be guided to abut against the second limiting surface 151.

[0065] In other embodiments, the second guide surface 152 may be omitted to simplify the construction of the second limiting member 150.

[0066] like Figure 6 As shown, in some embodiments of this application, the outer peripheral surface 124 of the gripper housing 120 is further provided with a third protrusion 123. The third protrusion 123 includes a third abutting side 1231 in the circumferential direction of the gripper housing 120. The third abutting side 1231 and the first abutting side 1211 of the first protrusion 121 are disposed on the same side in the circumferential direction of the gripper housing 120.

[0067] When multiple quick-release gripper mechanisms 100 are spaced apart on the same mounting plate 110, the first limiting member 130 is disposed between two adjacent gripper housings 120. The first limiting member 130 abuts against the first abutting side 1211 of the first protrusion 121 of one of the gripper housings 120 on one side in the circumferential direction, and abuts against the third abutting side 1231 of the third protrusion 123 of the adjacent gripper housing 120 on the other side.

[0068] The first abutting side 1211 is disposed on one side of the first protrusion 121 along the clockwise direction N1, and the third abutting side 1231 is disposed on one side of the third protrusion 123 along the clockwise direction N1. The first protrusion 121, the second protrusion 122, and the third protrusion 123 are spaced apart around the first axis P on the outer peripheral surface 124 of the gripper housing 120. The two gripper housings 120 share the same first limiting member 130. When the first protrusion 121 of one gripper housing 120 abuts against the first limiting member 130 from one side, the third protrusion 123 of the adjacent gripper housing 120 abuts against the first limiting member 130 from the other side.

[0069] The first limiting member 130 also includes a third limiting surface 136 and a third guiding surface 137 corresponding to the third protrusion 123. Their structures are similar to those of the first limiting surface 133 and the first guiding surface 134 corresponding to the first protrusion 121, and will not be described in detail here.

[0070] By setting the third protrusion 123, the gripper housing 120 can be fixed at multiple points in the circumference, improving the uniformity of force on the gripper housing 120; two adjacent gripper housings 120 share the same first limiting member 130, and the first limiting member 130 has limiting surfaces that cooperate with the first protrusion 121 and the third protrusion 123 respectively, which can reduce the number of components arranged on the mounting plate 110 and simplify the assembly process of the entire device.

[0071] In other embodiments, a limiting member corresponding to the third protrusion 123 may also be provided to simplify the construction of the first limiting member 130.

[0072] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments of this application, the first limiting member 130 further includes a top side limiting portion 135. When the first abutting side 1211 of the first protrusion 121 abuts against the first limiting member 130, the first protrusion 121 is located between the mounting plate 110 and the top side limiting portion 135 in the thickness direction (i.e., direction Z) of the mounting plate 110.

[0073] In other words, the side of the first limiting member 130 facing the claw housing 120 is recessed to form a groove, the first limiting surface 133 and the first guiding surface 134 respectively form the sidewalls of the groove, and the top limiting part 135 forms the top wall of the groove. When the first protrusion 121 abuts against the first limiting surface 133, the first protrusion 121 at least partially enters the groove, and the top limiting part 135 abuts against the top surface of the first protrusion 121.

[0074] This configuration allows the position of the first protrusion 121 to be fixed in the Z direction, preventing the gripper housing 120 from becoming loose relative to the mounting plate 110 in the Z direction.

[0075] In other embodiments, a separate component may be provided to press the claw housing 120 against the mounting plate 110 in the Z direction.

[0076] The second limiting member 150 has a top side limiting portion corresponding to the second protrusion 122, which is used to fix the position of the second protrusion 122 in the Z direction; the first limiting member 130 also has a top side limiting portion corresponding to the third protrusion 123, which is used to fix the position of the third protrusion 123 in the Z direction, which will not be described in detail here.

[0077] Due to the characteristics of the quick-release gripper mechanism 100 in this embodiment, the gripper assembly 160 is installed using the quick-release gripper mechanism 100. During maintenance and repair of the quick-release gripper mechanism 100, pressing each unlock button 140 allows for the removal of the corresponding gripper housing 120. The sealing device 200 using the quick-release gripper mechanism 100 not only facilitates maintenance and repair but also maintains good reliability and a long service life even after repeated loading and unloading.
