[0037] The following description, in conjunction with the accompanying drawings, describes a tooling and welding device for producing batteries according to an embodiment of the present invention.

[0038] This utility model aims to provide an embodiment of a welding device for battery production, the welding device including... Figures 1 to 3 The welding fixture shown.

[0039] In this embodiment, the welding fixture can fix the shell without flanges, which meets the needs of the welding process in battery manufacturing and overcomes the defects of the prior art.

[0040] In some specific embodiments of this utility model, welding fixtures can be applied to other production processes or equipment of batteries to address the defect that the casing is difficult to fix due to the lack of flange edges.

[0041] Therefore, referring to Figures 1 to 3 This utility model also aims to provide an embodiment of a tooling for battery production, wherein the welding fixture is the application of the tooling for battery production in the welding process or welding procedure.

[0042] In this embodiment, the tooling for producing batteries includes a mounting plate 250, and the mounting plate 250 is provided with a housing clamp 100.

[0043] In some specific embodiments of this utility model, the mounting plate 250 may also be provided with a battery cell clamp 200 to form a combined tooling, which facilitates the processing and assembly of the battery cell and the housing, thereby improving production efficiency.

[0044] For the housing clamp 100, the housing clamp 100 includes a first base 110 and a first fixing mechanism.

[0045] The first base 110 is mounted on the mounting plate 250. The first base 110 has a positioning groove 120 for placing the housing. The inner surface of the positioning groove 120 matches and positions with the outer surface of the housing. The positioning groove 120 has a first open side 130, which allows the battery cell to be installed into the housing.

[0046] In some specific embodiments of this utility model, the positioning groove 120 may have a second open side 240, the second open side 240 being located at the top of the positioning groove 120, and the first open side 130 being located on one side of the positioning groove 120. The first open side 130 and the second open side 240 cooperate to allow the housing to be inserted into the positioning groove 120.

[0047] That is, the first seat 110 is set vertically, and the positioning groove 120 is set on one side of the first seat 110, and is open to the upward and to the horizontal side.

[0048] To fix the housing, the first fixing mechanism includes a first fixing component, which includes a pressure block 141. The pressure block 141 is positioned on the first open side 130 and is used to abut and press against the edge of the housing and the first seat 110.

[0049] It is easy to understand that by setting the positioning groove 120 in this embodiment, the inner surface of the positioning groove 120 can match the outer surface of the housing to accurately position the housing, which facilitates the reprocessing of the housing, such as welding the electrode sheet to the housing, and also facilitates the assembly of the housing, such as installing the battery cell into the housing.

[0050] In this embodiment, by setting up a pressure block 141, the pressure block 141 can press down on the edge of the shell, thereby fixing the shell and preventing it from moving, for example, preventing the shell from tipping over when it is standing upright.

[0051] In this embodiment, by setting a pressure block 141, the pressure block 141 simultaneously presses the solid body forming the positioning groove 120 on the first seat body 110, and also makes the solid body forming the positioning groove 120 on the first seat body 110 share the force of the pressure block 141, so as to avoid the force of the pressure block 141 being concentrated on the edge of the shell and reduce the risk of deformation of the edge of the shell.

[0052] Meanwhile, the inner surface of the positioning groove 120 contacts the outer surface of the housing, which can support the edge of the housing and further reduce the risk of deformation of the edge of the housing.

[0053] In some specific embodiments of this utility model, the pressure block 141 can be moved closer to the edge of the shell, which satisfies the need for fixing and also allows for a loading space to be reserved between the pressure block 141 and the first seat 110.

[0054] In some specific embodiments of this utility model, the pressure block 141 can move parallel to the first base 110, thereby moving the pressure block 141 away from the first open side 130 of the positioning groove 120, reducing obstruction, facilitating material loading, and also facilitating the insertion of the battery cell into the housing.

[0055] In some specific embodiments of this utility model, the first fixing component may include a swing arm 140, one end of which is provided with a pressure block 141. The swing arm 140 swings to drive the pressure block 141 to press and release the pressure.

[0056] That is, by rotating, the pressure block 141 generates a composite displacement, which includes both displacement perpendicular to the first base 110 and displacement parallel to the first base 110, simplifying the structure and control difficulty, and making it low-cost and easy to implement.

[0057] It is easy to understand that this embodiment uses rotation and pressing, and therefore, by controlling the angle of rotation and pressing, it can adapt to the manufacturing error of the edge of the shell, and avoid the pressure block 141 acting on the first seat 110 without contacting the edge of the shell.

[0058] In some specific embodiments of this utility model, the pressure block 141 and the swing arm 140 can be integrated into a plate-shaped component, reducing the number of parts and lowering manufacturing costs.

[0059] In some specific embodiments of this utility model, the widths of the pressure block 141 and the swing arm 140 can be different. For example, the width of the pressure block 141 can be smaller than the width of the swing arm 140, so that the pressure block 141 presses a part of one side edge of the housing without affecting the processing of the housing, such as welding the battery cell tab to the housing.

[0060] In some specific embodiments of this utility model, the swing arm 140 can be connected to a motor, and the motor can directly drive the swing arm 140 to rotate, thereby meeting the need to drive the swing arm 140 to swing.

[0061] In some specific embodiments of this utility model, the other end of the swing arm 140 can be connected to a rotating shaft 150 and a transmission arm 160, and the transmission arm 160 is used to drive the swing arm 140 to rotate around the rotating shaft 150.

[0062] In other words, the swing arm 140 can be driven to swing by moving the transmission arm 160, which can reduce the space occupied and reduce manufacturing costs compared with directly setting the motor.

[0063] In some specific embodiments of this utility model, the first fixing mechanism may include a control member 170, a drive shaft 180 is provided at the end of the transmission arm 160 and one of the control members 170, and a transmission hole 190 is provided at the end of the transmission arm 160 and the other of the control members 170 to accommodate the drive shaft 180. An external force is applied to the control member 170, and the control member 170 drives the swing arm 140 to rotate through the drive shaft 180 and the transmission hole 190.

[0064] It is easy to understand that in this embodiment, by setting up the control component 170, the control component 170 can be pushed by the push rod to make the control component 170 displace, thereby changing the position of the transmission shaft 180 and the transmission hole 190, which can drive the transmission arm 160 to rotate, and then drive the swing arm 140 to rotate.

[0065] In this embodiment, the drive shaft 180 is disposed on the drive arm 160, and the drive hole 190 is disposed on the control component 170, which can reduce the manufacturing difficulty.

[0066] In some specific embodiments of this utility model, the transmission hole 190 can be semi-enclosed, so that the radial connection of the transmission shaft 180 to the transmission arm 160 does not need to be connected from both ends of the transmission shaft 180, thereby improving the connection strength and reducing the axial space occupied by the transmission shaft 180.

[0067] In some specific embodiments of this utility model, the control component 170 can be connected to a return spring. When the push rod moves away from the control component 170, the return spring can drive the control component 170 to move in the opposite direction, causing the swing arm 140 to rotate in the opposite direction.

[0068] In some specific embodiments of this utility model, the control component 170 can be connected to two transmission arms 160, which facilitates the rotation of the two swing arms 140. At the same time, the control component 170 can be installed through the two transmission arms 160, simplifying the installation structure.

[0069] At the same time, it has two swing arms 140 and two pressure blocks 141, which make it easy to press the two edges of the shell and distribute the force evenly. This can prevent the shell from tilting up and also eliminate the need for the pressure blocks 141 to span the shell, so as not to affect the processing and assembly of the shell.

[0070] In some specific embodiments of this utility model, the control member 170 can be located on the side of the first seat 110 facing away from the positioning groove 120, and the first seat 110 is provided with a channel that allows the swing arm 140 to pass through.

[0071] It is easy to understand that by placing the control component 170 on the side of the first base 110 facing away from the positioning groove 120, this embodiment not only facilitates the control component 170 to control the two pressure blocks 141 at the same time, but also avoids occupying the space around the first open side 130, and does not affect the processing and assembly of the housing.

[0072] In some specific embodiments of this utility model, the two pressure blocks 141 controlled by the control member 170 can abut against and press the two opposite edges of the housing, which satisfies the fixing requirements and reduces the number of pressure blocks 141.

[0073] In some specific embodiments of this utility model, the pressure block 141 can press the junction of the two edges of the shell to increase the strength of the edge of the shell against the pressure of the pressure block 141.

[0074] In some specific embodiments of this utility model, the battery cell clamp 200 and the housing clamp 100 can be rotated relative to each other so that the battery cell of the battery cell clamp 200 can be inserted into the housing of the housing clamp 100.

[0075] It is understood that the cell clamp 200 and the housing clamp 100 can rotate relative to each other. The housing clamp 100 can be fixed while the cell clamp 200 rotates, as in this embodiment. Alternatively, the housing clamp 100 can rotate while the cell clamp 200 is fixed. Or, the housing clamp 100 and the cell clamp 200 can rotate simultaneously to meet the need for the cell to be installed in the housing.

[0076] In some specific embodiments of this utility model, the battery cell clamp 200 may include a flipping frame 210 and an adjustment frame 220 disposed on the flipping frame 210. The adjustment frame 220 is used to install the battery cell and can be adjusted in position relative to the flipping frame 210. The adjustment direction of the adjustment frame 220 is perpendicular to the rotation axis of the flipping frame 210.

[0077] It is easy to understand that in this embodiment, by setting the adjustment frame 220, when the battery cell rotates into the housing, the adjustment frame 220 generates a radial displacement, causing the position of the edge of the battery cell to change height, adjusting the posture of the battery cell, and facilitating the battery cell to enter the housing.

[0078] Specifically, when the battery cell rotates, its diagonal is nearly vertical, and one top edge of the battery cell is higher than the other, making the height of the battery cell approximately the same as its diagonal. This makes it difficult to install the battery cell into the housing. The adjustment bracket 220 then moves to adjust the position of the battery cell, causing the highest top edge to drop. Since there is also a height difference between the two bottom edges of the battery cell, the gap between the higher bottom edge of the battery cell and the housing can be used to lower the height of the battery cell, making it easier for the higher top edge of the battery cell to enter the housing and meet the housing installation requirements.

[0079] In some specific embodiments of this utility model, the battery production equipment can be equipped with a track, and the adjustment frame 220 has rollers that abut against the track. The adjustment frame 220 can be dynamically adjusted by the track to meet the requirements of casing insertion.

[0080] In some specific embodiments of this utility model, the flipping frame 210 can be mounted on the first base 110 to simplify the structure. At the same time, the relative positions of the housing clamp 100 and the cell clamp 200 are accurate, reducing installation and adjustment.

[0081] In some specific embodiments of this utility model, the adjustment frame 220 may be provided with a side push block 230, which limits the battery cell in a direction perpendicular to the rotation axis of the flipping frame 210.

[0082] It is easy to understand that by setting the side push block 230, this embodiment can restrict the top of the upright battery cell and prevent the battery cell from tipping over and affecting the inlet operation.

[0083] In some specific embodiments of this utility model, the adjustment frame 220 can have a recess to avoid the pressure block 141, so that the pressure block 141 can be opened when it is inserted into the shell, avoiding the pressure block 141 from blocking and not affecting the entry of the battery cell into the shell.

[0084] In some specific embodiments of this utility model, the mounting plate 250 may be provided with two sets of housing clamps 100 and cell clamps 200 to improve output.

[0085] In some specific embodiments of this utility model, the mounting plate 250 can be equipped with guide rails to facilitate the transfer of tooling between various processes.

[0086] In some specific embodiments of this utility model, the mounting plate 250 can have a V-groove 260, and the insertion rod can be inserted into the V-groove 260 in a direction perpendicular to the guide rail, which can position the tooling and make the tooling in each station position accurately.
