[0057] In related technologies, during battery assembly, the battery casing and battery cell are typically positioned separately using tooling and assembled at designated assembly points, resulting in poor assembly accuracy. Integrating the battery casing and battery cell into a single tooling involves rotation during assembly, making it impossible to prevent contact with the battery cell or battery body, thus leading to a higher assembly defect rate. Simultaneously, the battery casing needs precise positioning and a consistent appearance, while minimizing manual intervention.

[0058] Based on the above concepts and problems, this invention proposes an assembly fixture 100. The assembly fixture 100 is used in the battery assembly process to position and place battery components. It is understood that a battery includes a battery casing and battery cells, and of course, other components, which are not limited here.

[0059] Please refer to the reference. Figures 1 to 4 As shown, in this embodiment of the invention, the assembly fixture 100 includes a base 1, a flipping mechanism 2, and a protective cover 3. The base 1 is provided with a placement groove 11 for placing a battery casing. The flipping mechanism 2 is movably disposed on the base 1 and is disposed adjacent to the placement groove 11. The side of the flipping mechanism 2 facing the placement groove 11 is provided with a receiving groove 231 for placing a battery cell. The protective cover 3 is detachably connected to the flipping mechanism 2 and covers the opening of the receiving groove 231.

[0060] In this embodiment, the base 1 is used to install, fix, and support components such as the flipping mechanism 2 and the protective cover 3; that is, the base 1 provides an installation foundation for components such as the flipping mechanism 2 and the protective cover 3. It can be understood that the base 1 can be a mounting seat, support seat, support frame, base plate, tooling platform, or plane, etc.

[0061] It should be noted that the assembly fixture 100 is used in battery assembly equipment. The assembly fixture 100 is located in the output belt or conveyor channel of the production line to position and transport the battery casing and battery cell to the assembly station for assembly. Understandably, the base 1 has a support surface that contacts or abuts against the flow channel and a mounting surface facing away from the support surface. The support surface and the mounting surface are located on opposite sides of the base 1. The mounting surface of the base 1 is provided with a placement groove 11.

[0062] Understandably, the placement groove 11 can be a recessed structure on the mounting surface of the base 1, or it can be a groove structure formed by a boss protruding from the mounting surface of the base 1; this is not limited here. Optionally, the placement groove 11 can be a circular groove, an elliptical groove, a square groove, a triangular groove, or other polygonal or irregularly shaped groove; this is not limited here. Specifically, the shape and outline of the placement groove 11 are consistent with the shape and outline of the battery casing.

[0063] In this embodiment, the placement slot 11 is used to place and position the battery casing placed in the placement slot 11. The flipping mechanism 2 is disposed on the mounting surface of the base 1 and located on one side of the placement slot 11, adjacent to the side wall of the placement slot 11. This ensures the relative position of the battery cell in the receiving slot 231 on the flipping mechanism 2 and the battery casing in the placement slot 11, thereby improving the assembly accuracy during assembly, and also avoids interference of the flipping mechanism 2 with the placement of the battery casing in the placement slot 11.

[0064] Optionally, the flipping mechanism 2 is perpendicular to the mounting surface of the base 1. In this embodiment, the flipping mechanism 2 is movably mounted on the base 1, for example, the flipping mechanism 2 is rotatably connected, swing-connected, or slidably connected to the base 1, etc., which is not limited here. It can be understood that by movably mounting the flipping mechanism 2 on the mounting surface of the base 1, the flipping mechanism 2 can drive the battery cell in the receiving slot 231 to move relative to the base 1, so as to facilitate the battery to avoid obstacles or adjust the assembly position during the assembly process, etc., which is not limited here.

[0065] In this embodiment, by providing a protective cover 3, the protective cover 3 is detachably connected to the flipping mechanism 2 and covers the opening of the receiving groove 231. This allows the protective cover 3 to protect the battery cell inside the receiving groove 231, and also makes it easy to disassemble the protective cover 3 to assemble the battery cell with the battery casing.

[0066] Optionally, the protective cover 3 can be a plate-like structure or a cover structure, etc., and there is no limitation here.

[0067] The assembly fixture 100 of the present invention provides a placement groove 11 on the base 1, thereby placing and positioning the battery casing using the placement groove 11. The flipping mechanism 2 is movably disposed on the base 1 and disposed adjacent to the placement groove 11, so that the position between the flipping mechanism 2 and the placement groove 11 is consistent. A receiving groove 231 is provided on the side of the flipping mechanism 2 facing the placement groove 11, thereby placing and positioning the battery cell using the receiving groove 231, ensuring the positional accuracy requirements of the battery cell and the battery casing during the assembly process. At the same time, by detachably connecting the protective cover 3 to the flipping mechanism 2, the protective cover 3 covers the opening of the receiving groove 231, thereby protecting the battery cell in the receiving groove 231 and effectively preventing contact with the battery cell during the assembly process.

[0068] In one embodiment, the flipping mechanism 2 includes a rotating arm 21 and a support plate 23. One end of the rotating arm 21 is rotatably connected to the base 1 and is disposed adjacent to the placement slot 11. The support plate 23 is connected to the end of the rotating arm 21 away from the base 1. On the side of the support plate 23 facing the placement slot 11, there are multiple support blocks 232, which together form a receiving slot 231. The periphery of the protective cover 3 is detachably connected to the support blocks 232 to cover the opening of the receiving slot 231.

[0069] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the flipping mechanism 2 is movably connected to the base 1 via the rotating arm 21, so that the rotating arm 21 supports the support plate 23 and is located above the mounting surface of the base 1, thereby effectively avoiding interference between the support plate 23 and the battery casing in the placement slot 11 when it is placed or removed.

[0070] Understandably, the rotating arm 21 can be a long, narrow plate, column, or other structure. Optionally, there are two rotating arms 21, spaced apart, with both ends of the support plate 23 connected to the two rotating arms 21 respectively. This arrangement can improve the connection stability between the flipping mechanism 2 and the base 1 using the two rotating arms 21, and also ensure the stability of the flipping mechanism 2 when folding relative to the base 1.

[0071] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, a rotating seat 12 is also provided near the placement slot 11 on the base 1. One end of the rotating arm 21 is rotatably connected to the rotating seat 12, and the other end of the rotating arm 21 is connected to the support plate 23. It can be understood that the rotating seat 12 has a rotating groove, and one end of the rotating arm 21 extends into this rotating groove and is connected by a rotating shaft, so that the rotating arm 21 is rotatably connected to the rotating seat 12. Optionally, the rotating groove has a through-slot structure, and the rotation direction of the rotating arm 21 is perpendicular to the plane of the support plate 23.

[0072] Optionally, the two rotating arms 21 are located on opposite sides of the placement groove 11, and the support plate 23 is opposite to the sidewall between the opposite sides of the placement groove 11. In this embodiment, by providing a support block 232 on the support plate 23, the protective cover 3 is supported by the support block 232, and the battery cell is positioned and installed at the same time.

[0073] In this embodiment, multiple support blocks 232 are disposed around the periphery of the support plate 23, forming a receiving groove 231. It is understood that the periphery of the protective cover 3 is detachably connected to the support blocks 232 to cover the opening of the receiving groove 231. It should be noted that the detachable connection between the protective cover 3 and the support plate 23 can be a snap-fit ​​connection, a plug-in fit, a screw connection, a pin connection, or a magnetic connection, etc., and is not limited here.

[0074] Optionally, at least one of the support block 232 and the protective cover 3 is provided with a magnetic attractor 234, and the protective cover 3 is magnetically connected to the support block 232 through the magnetic attractor 234. In this embodiment, the magnetic attractor 234 can be a magnet, a magnetic adsorption structure, etc. The magnetic attractor 234 can be disposed on the support plate 23, or on the protective cover 3, or simultaneously on both the support plate 23 and the protective cover 3. It is understood that when the magnetic attractor 234 is disposed on one of the support block 232 and the protective cover 3, the other component is made of ferrous or magnetic material, which is not limited here.

[0075] In order to achieve the positioning of the protective cover 3, ensure that the protective cover 3 is installed on the support plate 23 and avoid contact or collision with the battery cell, in this embodiment, one of the support block 232 and the protective cover 3 is provided with a positioning post 235, and the other is provided with a positioning hole 31. When the protective cover 3 is connected to the support block 232, the positioning post 235 is limited to the positioning hole 31.

Optionally, there are multiple positioning posts 235 and multiple positioning holes 31, and the multiple positioning posts 235 are provided in a one-to-one correspondence with the multiple positioning holes 31.

[0077] Optionally, the bottom wall of the receiving groove 231 is provided with an adsorption member 233, which is used to adsorb and fix the battery cell. In this embodiment, as... Figure 2 As shown, by providing an adsorption element 233 on the support plate 23, the adsorption element 233 is positioned within the receiving groove 231, thereby using the adsorption element 233 to adsorb and fix the battery cell. Optionally, the adsorption element 233 can be a suction cup structure, a magnetic structure, etc., which is not limited here.

[0078] In one embodiment, the base 1 is also provided with a rotating seat 12 near the placement slot 11. One end of the rotating arm 21 is rotatably connected to the rotating seat 12, and the end of the rotating arm 21 away from the rotating seat 12 is provided with a guide post. The base 1 is also provided with a column 13 near the rotating seat 12. The end of the column 13 away from the base 1 is provided with an adjustment hole 131, and the guide post is movably inserted into the adjustment hole 131. When the rotating arm 21 rotates relative to the rotating seat 12, the guide post moves along the adjustment hole 131.

[0079] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, by providing an adjustment hole 131 on the column 13 and a guide post on the rotating arm 21, the rotation angle of the rotating arm 21 driving the support plate 23 can be adjusted and limited using the adjustment hole 131. Optionally, the adjustment hole 131 is provided in an arc shape.

[0080] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the adjustment hole 131 has a first end 132 and a second end 133. When the guide post is located at the first end 132, the support plate 23 is perpendicular to the base 1. When the guide post is located at the second end 133, the support plate 23 rotates toward the side away from the placement groove 11.

[0081] It should be noted that the included angles formed by the first end 132 and the second end 133 of the adjusting hole 131 and the rotation center of the rotating arm 21 are respectively greater than 0° and less than 45°. Optionally, the rotation angle of the support plate 23 relative to the base 1 is greater than 0° and less than 45°. In this embodiment, when the guide post is located at the first end 132, the support plate 23 is perpendicular to the base 1; when the guide post is located at the second end 133, the support plate 23 rotates toward the side away from the placement groove 11.

[0082] To achieve locking of the rotation angle, in one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the flipping mechanism 2 also includes a handwheel 22, which is connected to one end of the guide post that passes through the adjustment hole 131 and is used to lock the rotating arm 21.

[0083] Understandably, the handwheel 22 is designed to both facilitate the user's rotation of the rotating arm 21 around the rotating base 12 and to lock the rotation angle of the rotating arm 21. It should be noted that the specific structure of the handwheel 22 can refer to existing technologies that enable adjustment and locking, and is not limited here.

[0084] In one embodiment, the base 1 is further provided with a mounting cavity 141 and a plurality of movable holes 142 connecting the mounting cavity 141 and the placement groove 11. The plurality of movable holes 142 are distributed on at least two side walls of the placement groove 11. The assembly fixture 100 further includes a positioning mechanism 4. The positioning mechanism 4 includes a linkage component 41 and a plurality of grippers 42. The linkage component 41 is movably disposed in the mounting cavity 141. One end of each gripper 42 is connected to the linkage component 41. The other end of each gripper 42 moves through a movable hole 142 and protrudes from the opening of the placement groove 11.

[0085] In this embodiment, as Figures 1 to 3 , Figure 5 and Figure 6As shown, by setting the positioning mechanism 4, the gripper 42 of the positioning mechanism 4 is used to position and lock the battery casing in the placement slot 11, so as to prevent the battery casing from leaving the placement slot 11 or shifting within the placement slot 11.

[0086] Understandably, the base 1 includes a base plate and a cover plate, which are connected and form a mounting cavity 141 between them. In this embodiment, the side of the base plate facing away from the cover plate forms a support surface, and the side of the cover plate facing away from the base plate forms a mounting surface. Optionally, the cover plate has a through hole at the position corresponding to the placement groove 11, so that the cover plate and the base plate cooperate to form the placement groove 11.

[0087] In this embodiment, the cover plate of the base 1 is provided with a plurality of movable holes 142 communicating with the mounting cavity 141 and the placement groove 11, and the plurality of movable holes 142 are arranged around the placement groove 11. Optionally, the plurality of movable holes 142 are located on at least two side walls of the placement groove 11. One end of each gripper 42 is connected to the linkage component 41, and the other end moves through a movable hole 142 and protrudes from the opening of the placement groove 11. It can be understood that by providing the linkage component 41 in the mounting cavity 141, the linkage component 41 can simultaneously drive the plurality of grippers 42 to simultaneously lock or release the battery casing in the placement groove 11.

[0088] In one embodiment, the placement slot 11 has a first sidewall 111 and a second sidewall 112 that are adjacent and arranged at an angle. The linkage assembly 41 includes a connecting rod 411 and a plurality of reset members 412. The connecting rod 411 includes a first connecting rod 4111 and a second connecting rod 4112 disposed in the mounting cavity 141. The first connecting rod 4111 extends along the first sidewall 111 and is connected to at least one gripper 42. The second connecting rod 4112 extends along the second sidewall 112 and is movably connected to at least one gripper 42. One end of the first connecting rod 4111 and the second connecting rod 4112 are rotatably connected, and the end of the second connecting rod 4112 adjacent to the first connecting rod 4111 is rotatably connected to the inner wall of the mounting cavity 141. Each reset member 412 is disposed on the cavity wall of the mounting cavity 141 and a gripper 42 on the side facing away from the placement slot 11.

[0089] In this embodiment, as Figure 3 As shown, the placement groove 11 has an adjacent first sidewall 111 and a second sidewall 112, which are arranged at an angle. Optionally, the first sidewall 111 and the second sidewall 112 are arranged perpendicularly.

[0090] Understandably, the first link 4111 and the second link 4112 of the connecting rod 411 are movably disposed within the mounting cavity 141. The first link 4111 extends along the first side wall 111 and is connected to at least one gripper 42, while the second link 4112 extends along the second side wall 112 and is movably connected to at least one gripper 42. In order for the first link 4111 and the second link 4112 to cooperate with each other to enable the simultaneous operation of multiple grippers 42, one end of the first link 4111 and the second link 4112 are rotatably connected, and the end of the second link 4112 adjacent to the first link 4111 is rotatably connected to the inner wall of the mounting cavity 141.

[0091] In this embodiment, the reset member 412 can be an elastic structure, such as a reset spring, a telescopic spring, or a spring sheet, etc., and is not limited thereto. The reset member 412 is disposed between the side of the gripper 42 facing away from the placement groove 11 and the cavity wall of the mounting cavity 141.

[0092] It should be noted that the positioning mechanism 4 has a clamping state in which multiple grippers 42 approach the placement groove 11 to clamp the battery casing, and a releasing state in which multiple grippers 42 move away from the placement groove 11 to release the battery casing. Understandably, in the clamping state, the reset member 412 pushes the multiple grippers 42 back to their original position and closer to the placement groove 11; that is, the elasticity of the reset member 412 pushes the grippers 42, causing the grippers 42 to lock or clamp the battery casing within the placement groove 11. In the releasing state, the connecting rod 411 moves the multiple grippers 42 away from the placement groove 11. That is, when the first connecting rod 4111 drives the grippers 42 on the first sidewall 111 away from the placement groove 11, the first connecting rod 4111 drives the second connecting rod 4112 to swing, causing the second connecting rod 4112 to push the grippers on the second sidewall 112 away from the placement groove 11, thereby releasing the battery casing within the placement groove 11.

[0093] In order to enable the connecting rod 411 to drive the multiple grippers 42 away from the placement slot 11 and keep the grippers 42 in the state of releasing the battery casing in the placement slot 11, so as to facilitate the user to put or take the battery casing in the placement slot 11 or to perform other work.

[0094] In one embodiment, the base 1 is further provided with a locking hole 144 communicating with the mounting cavity 141. The first connecting rod 4111 is provided with a locking groove 4113 and an opening 4114 communicating with the locking groove 4113 at one end adjacent to the second connecting rod 4112. The linkage assembly 41 also includes a locking rod 413 and an elastic member 414. The locking rod 413 includes a first segment 4131 and a second segment 4132 connected to each other. The cross-sectional area of ​​the second segment 4132 is larger than the cross-sectional area of ​​the first segment 4131. The end of the first segment 4131 away from the second segment 4132 is movably inserted through the locking hole 144. The elastic member 414 is disposed between the second segment 4132 and the cavity wall of the mounting cavity 141.

[0095] Understandably, by setting a locking element, the connecting rod 411 is locked in place to keep the gripper 42 in a state where it is released from the battery casing in the placement slot 11. In this embodiment, the locking element includes a locking rod 413 and an elastic element 414. Of course, in other embodiments, the locking element may be an electromagnetic lock or other structures capable of locking, which are not limited here.

[0096] In this embodiment, in the clamped state, the locking rod 413 is pressed to disengage the second segment 4132 from the locking groove 4113, and the first segment 4131 moves from the locking groove 4113 to the opening 4114; in the released state, the first segment 4131 moves from the opening 4114 to the locking groove 4113, and the elastic member 414 pushes the second segment 4132 into the locking groove 4113 to lock the first connecting rod 4111.

[0097] It should be noted that the locking rod 413 can be a cylindrical structure. The first segment 4131 and the second segment 4132 of the locking rod 413 are cylindrical, and the diameter of the first segment 4131 is smaller than the diameter of the second segment 4132. In this embodiment, the diameter of the opening 4114 is larger than the diameter of the first segment 4131 but smaller than the diameter of the second segment 4132, and the diameter of the locking groove 4113 is greater than or equal to the diameter of the second segment 4132. That is, the opening 4114 only allows the first segment 4131 to pass through, and does not allow the second segment 4132 to pass through.

[0098] In the released state, the first segment 4131 moves from the opening 4114 to the locking groove 4113, and the elastic member 414 pushes the second segment 4132 into the locking groove 4113, so that the locking rod 413 uses the second segment 4132 to cooperate with the locking groove 4113 to lock the first link 4111, so that the first link 4111 is in a stationary state.

[0099] To facilitate the operation of the locking lever 413, such as Figures 1 to 3 , Figure 5 and Figure 6 As shown, the locking lever 413 also includes a button part 4133, which is connected to the end of the first segment 4131 that passes through the locking hole 144. Understandably, the user can unlock the first link 4111 by pressing the button part 4133.

[0100] In this embodiment, in the released state, the second segment 4132 is located within the locking groove 4113 and engages with the locking groove 4113 to lock the first connecting rod 4111, thus keeping the first connecting rod 4111 stationary. By pressing the button 4133, the second segment 4132 compresses the elastic member 414, causing the first segment 4131 to be located within the locking groove 4113. At this time, the diameter of the first segment 4131 is smaller than the diameter of the opening 4114. The first connecting rod 4111 is reset and moved under the elastic action of the reset member 412, so that the first segment 4131 moves relative to the first connecting rod 4111 from the locking groove 4113 toward the opening 4114.

[0101] To prevent the locking rod 413 from fully disengaging from the first connecting rod 4111 and thus returning to its original position under the elastic action of the elastic member 414, preventing the second segment 4132 of the locking rod 413 from entering the locking groove 4113 through the opening 4114, in this embodiment, a sliding platform 4134 is formed at the connection between the first segment 4131 and the second segment 4132, and the sliding platform 4134 slides against the surface of the first connecting rod 4111.

[0102] Understandably, after pressing the button 4133, when the first link 4111 moves to its reset position under the elastic action of the reset member 412, the surface of the first link 4111 moves along the sliding table 4134 but does not disengage from the sliding table 4134, so that the locking rod 413 is always in the state of compressing the elastic member 414. Thus, when the first link 4111 is driven to compress the reset member 412 and the gripper 42 is driven away from the placement groove 11, the surface of the first link 4111 moves along the sliding table 4134, so that the first segment 4131 moves from the opening 4114 toward the locking groove 4113 relative to the first link 4111. When the first segment 4131 is in the locking groove 4113, the locking rod 413 rises under the elastic action of the elastic member 414, so that the second segment 4132 is located in the locking groove 4113 and cooperates with the locking groove 4113 to lock the first link 4111, so that the first link 4111 is in a stationary state.

[0103] Optionally, such as Figure 2 As shown, the bottom wall of the mounting cavity 141 is provided with a clearance groove 146 corresponding to the elastic member 414. The end of the elastic member 414 away from the second section 4132 is accommodated and confined within the clearance groove 146. It can be understood that the setting of the clearance groove 146 is beneficial to provide clearance space for the pressing and moving of the locking rod 413, and at the same time provides installation and limiting space for the elastic member 414.

[0104] In this embodiment, as Figures 1 to 3 , Figure 5As shown, the base 1 is also provided with an unlocking hole 145 communicating with the mounting cavity 141. The linkage component 41 also includes an unlocking button 415, which passes through the unlocking hole 145 and is connected to the first connecting rod 4111. It is understood that the unlocking button 415 is designed to allow the user to pull or move the first connecting rod 4111 within the mounting cavity 141, thereby enabling the linkage component 41 to move within the mounting cavity 141 and thus driving the movement of multiple grippers 42.

[0105] Optionally, such as Figure 2 and Figure 5 As shown, the bottom wall of the mounting cavity 141 is provided with a slide rail 143 corresponding to each gripper 42, and each gripper 42 is provided with a slide groove 421, which slides in cooperation with the slide rail 143.

[0106] In one embodiment, such as Figure 2 and Figure 3 As shown, the base 1 is also provided with a contoured baffle 15. The contoured baffle 15 is located below the flipping mechanism 2 and is flush with the side wall of the placement groove 11. The contoured baffle 15 is arc-shaped on the side facing the placement groove 11 and partially protrudes from the opening of the placement groove 11.

[0107] Understandably, by setting the contoured baffle 15, which is located on the side wall opposite to the first side wall 111 of the placement groove 11, the battery casing can be placed into the placement groove 11 when the gripper 42 moves away from it, and the contoured baffle 15 can limit the positioning of the battery casing. In this embodiment, the contoured baffle 15 and the gripper 42 cooperate to lock and position the battery casing in the placement groove 11.

[0108] In this embodiment, the contoured retaining wall 15 is arc-shaped on the side facing the placement groove 11 and extends partially toward the center of the placement groove 11 to protrude from the opening of the placement groove 11. Optionally, the gripper 42 is arc-shaped on the side facing the placement groove 11 and extends toward the center of the placement groove 11 to protrude from the opening of the placement groove 11.

[0109] The present invention also proposes an assembly equipment, which includes an equipment body and the aforementioned assembly fixture 100, the assembly fixture 100 being connected to the equipment body.
