Description
Technical Field
[0001] This application relates to the field of battery processing technology, and more specifically, to a welding positioning device. Background Technology
[0002] With the rapid development of electronic products such as mobile phones and fitness trackers, higher demands are being placed on the batteries that power them. To improve charging speed and battery life, many batteries adopt a dual-cell structure, with two cells arranged in a V-shape and welded to the top cover. Among these, the dual-cell V-shaped welding is widely adopted because it can improve battery capacity and energy density, optimize battery layout, and adapt to irregularly shaped products.
[0003] In dual-cell V-welding, controlling the angle between the two cells is crucial, as the angle directly affects the battery capacity. Current technology uses a cell-lifting device to support the two cells during welding, maintaining a constant angle. However, the angle of this existing device is not adjustable, resulting in poor consistency in the cell angle and making it difficult to verify a suitable angle. Utility Model Content

A top cover placement area is provided between the sides of the two battery cell trays that are close to each other.
[0007] Optionally, the drive assembly includes: a first drive member and a support slider connected to the output end of the first drive member.

[0008] Optionally, the base plate is provided with a second driving member and a limiting slider connected to the output end of the second driving member. The output end of the second driving member reciprocates along a second linear direction, which is parallel to the rotation axis of the cell tray. The limiting slider extends into or out of the two cell trays under the drive of the second driving member. When the limiting slider extends into the two cell trays, one limiting surface of the limiting slider abuts against one cell and the other limiting surface abuts against the other cell.

[0013] Optionally, the base plate is provided with a top cover positioning plate, and the surface of the top cover positioning plate opposite to the base plate is provided with a top cover positioning groove. The top cover positioning groove is located between two battery cell support plates and is used to accommodate the top cover. The top cover positioning groove is adapted to the top cover.
[0014] Optionally, the top cover positioning plate is provided with two second clearance slots. One second clearance slot is used to avoid a set of drive components and a cell tray that is driven and connected to the drive components. The other second clearance slot is used to avoid another set of drive components and a cell tray that is driven and connected to the drive components.
[0015] Optionally, the top cover positioning plate is provided with at least two sets of second baffle assemblies. The second baffle assembly includes two tray side baffles.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] Please refer to Figure 1 This application provides a welding positioning device 10 for welding an adapter piece 30 connecting two battery cells 20 to a top cover 40. Previously, the tabs 21 of the two battery cells 20 had already been welded to the adapter piece.
[0029] Please refer to the reference. Figure 2The welding positioning device 10 includes: a base plate 11, two battery cell support plates 12 disposed on the base plate 11, and two sets of drive components. The two battery cell support plates 12 are arranged in a V-shape. The sides of the two battery cell support plates 12 that are close to each other are rotatably connected to the base plate 11. One set of drive components is driven connected to one battery cell support plate 12, and the other set of drive components is driven connected to the other battery cell support plate 12 to drive the battery cell support plates 12 to rotate respectively. A top cover 40 placement area is provided between the sides of the two battery cell support plates 12 that are close to each other.
[0030] The cell support plate 12 supports the cell 20, and the top cover 40 placement area is used to place the top cover 40. The top cover 40 placement area can be located on the base plate 11 or on other parts set on the base plate 11. Before welding, the top cover 40 must be placed in the top cover 40 placement area, and then the two cells 20 are placed on the upper surfaces of the two cell support plates 12 respectively, so that the connecting piece between the two cells 20 is aligned with the welding area of the top cover 40. Driven by the drive assembly, the cell support plate 12 rotates around the connecting axis between the cell support plate 12 and the base plate 11 (that is, the rotation axis of the cell support plate 12). In this way, the included angle between the two cell support plates 12 can be adjusted, and thus the included angle between the two cells 20 can be adjusted.
[0031] The two cell support plates 12 of the aforementioned welding positioning device 10 are arranged in a V-shape and are rotatably mounted on the base plate 11. Driven by the drive assembly, the two cell support plates 12 can rotate around the connecting axis between themselves and the base plate 11, thereby adjusting the included angle between the two cells 20. Therefore, the aforementioned welding positioning device 10 can improve the consistency of the included angle of the cells during batch welding, reduce the difficulty of verifying the included angle of the cells, and verify the appropriate angle more quickly.
[0032] It should be noted that in this embodiment, the structure of the drive component is not limited, as long as it can adjust the included angle between the two cell support plates 12.
[0033] Optionally, the drive assembly includes: a first drive member 131 and a support slider 132 connected to the output end of the first drive member 131. The output end of the first drive member 131 reciprocates along a first linear direction X. The first linear direction X is perpendicular to the rotation axis of the cell support plate 12 and parallel to the surface of the base plate 11. The support slider 132 abuts against the surface of the cell support plate 12 facing the base plate 11.
[0034] The output end of the first driving member 131 drives the support slider 132 to reciprocate along the first linear direction X. It can be understood that the first linear direction X includes two opposite linear directions: one is a linear direction close to the rotation axis of the cell tray 12, and the other is a linear direction away from the rotation axis of the cell tray 12.
[0035] When the support slider 132 moves along a straight line close to the rotation axis of the cell support plate 12, the support slider 132 lifts the cell support plate 12 upward. At this time, the included angle between the two cell support plates 12 decreases, and correspondingly, the included angle between the two cells 20 decreases. When the support slider 132 moves along a straight line away from the rotation axis of the cell support plate 12, the cell support plate 12 falls downward. At this time, the included angle between the two cell support plates 12 increases, and correspondingly, the included angle between the two cells 20 increases.
[0036] The first driving component 131 can be a cylinder, and the supporting slider 132 is connected to the piston rod of the cylinder. The extension and retraction of the piston rod can drive the supporting slider 132 to move. Alternatively, the first driving component 131 can be a linear motor, and the supporting slider 132 can be fixed on the output slider of the linear motor.
[0037] In other embodiments, the drive assembly may also include a rotary motor and a rotating shaft. The rotating shaft is fixed on the cell support plate 12 and driven by the output shaft of the rotary motor. The rotary motor drives the rotating shaft to rotate, thereby driving the cell support plate 12 to rotate, so as to adjust the cell angle.
[0038] Because the two cell trays 12 are tilted, after the cell 20 is placed on the cell tray 12, if the friction between the cell 20 and the cell tray 12 is insufficient, the cell 20 will slide down the surface of the cell tray 12 under the action of gravity. To avoid this situation, optionally, please refer to... Figure 1 The base plate 11 is provided with a second driving member 141 and a limiting slider 142 connected to the output end of the second driving member 141. The output end of the second driving member 141 reciprocates along the second linear direction Y, which is parallel to the rotation axis of the cell support plate 12. The limiting slider 142 extends into or out between the two cell support plates 12 under the drive of the second driving member 141.
[0039] When the limiting slider 142 extends between the two cell support plates 12, one limiting surface 1421 of the limiting slider 142 abuts against one cell 20, and the opposite limiting surface 1421 abuts against the other cell 20. This prevents the cell 20 from sliding downwards along the surface of the cell support plate 12 under gravity, improving cell position consistency during batch welding. After welding is completed, the limiting slider 142 retracts from between the two cell support plates 12, allowing the welded cell 20 and top cover 40 to be removed.
[0040] The second driving component 141 can also be a driving structure such as a cylinder or linear motor whose output end reciprocates in a straight line.
[0041] To further improve the limiting accuracy and prevent the cell 20 from deflecting, optionally, there are two second driving members 141 and two limiting sliders 142. One limiting slider 142 is connected to the output end of one second driving member 141, and the other limiting slider 142 is connected to the output end of the other second driving member 141. The two limiting sliders 142 are symmetrically distributed along the second straight line direction Y, and the two second driving members 141 are symmetrically distributed along the second straight line direction Y.
[0042] When a limiting action is required, both limiting sliders 142 extend between the two cell support plates 12, simultaneously limiting the cell 20 from both sides. After welding is completed, both limiting sliders 142 retract from between the two cell support plates 12.
[0043] Optionally, please refer to the following: Figure 3 The limiting surface 1421 of the limiting slider 142 is inclined relative to the base plate 11 so as to fit against the side of the battery cell 20.
[0044] The surface on the limiting slider 142 that abuts against the battery cell 20 is the limiting surface 1421. Since the sides of the two battery cells 20 that are close to each other are inclined relative to the base plate 11, the limiting surface 1421 is also set to be inclined relative to the base plate 11. When the limiting surface 1421 is parallel to the side of the battery cell 20, the limiting surface 1421 can be fitted to the side of the battery cell 20 to further improve the limiting effect.
[0045] The limiting slider 142 moves between the two cell support plates 12, and the top cover 40 is also placed between the two cell support plates 12. In order to avoid interference between the limiting slider 142 and the top cover 40, optionally, the limiting slider 142 is provided with a first clearance groove 1422 on the side away from the second driving member 141. The first clearance groove 1422 is used to avoid the top cover 40 placed between the two cell support plates 12.
[0046] In the aforementioned embodiment, a limiting slider 142 is provided to limit the end of the battery cell 20 in order to prevent the battery cell 20 from sliding down. However, the battery cell 20 can still move on the battery cell support plate 12 in a direction parallel to the rotation axis of the battery cell support plate 12.
[0047] Therefore, in order to further limit the position of cell 20 and improve the welding quality, optionally, please refer to Figure 1 The cell support plate 12 is provided with at least one set of first baffle assembly. The first baffle assembly includes two cell side baffles 15. The sides of the two cell side baffles 15 that are close to each other abut against the two opposite sides of the cell 20 in the second straight direction Y. The second straight direction Y is parallel to the rotation axis of the cell support plate 12.
[0048] Preferably, the two cell-side baffles 15 are spaced apart along the second straight line direction Y, that is, symmetrically arranged on opposite sides of the cell 20. Of course, the two cell-side baffles 15 can also be staggered on opposite sides of the cell 20.
[0049] When there are two or more sets of first baffle assemblies, the two or more sets of first baffle assemblies are distributed along a direction parallel to the upper surface of the baffle of the cell 20 and perpendicular to the rotation axis of the baffle of the cell 20.
[0050] Optionally, a top cover positioning plate 16 is provided on the base plate 11. The surface of the top cover positioning plate 16 opposite to the base plate 11 is provided with a top cover positioning groove. The top cover positioning groove is located between two battery cell support plates 12. The top cover positioning groove is used to accommodate the top cover 40. The top cover positioning groove is adapted to the top cover 40.
[0051] It can be understood that the top cover positioning groove is the placement area of the top cover 40, and the inner wall of the top cover positioning groove is adapted to the outer wall of the top cover 40, thereby limiting the position of the top cover 40. The top cover positioning plate 16 should avoid interference with the cell support plate 12, the drive assembly, the second drive component 141 and the limiting slider 142.
[0052] Optionally, the top cover positioning plate 16 is provided with two second clearance slots 161. One second clearance slot 161 is used to avoid a set of drive components and the cell support plate 12 driven by the drive components, and the other second clearance slot 161 is used to avoid another set of drive components and the cell support plate 12 driven by the drive components.
[0053] Optionally, the top cover positioning plate 16 is provided with at least two sets of second baffle assemblies. The second baffle assembly includes two tray side baffles 162. The two sides of the two tray side baffles 162 that are close to each other abut against the two opposite sides of the cell tray 12 in the second straight direction Y. The second straight direction Y is parallel to the rotation axis of the cell tray 12. At least one set of second baffle assemblies abuts against one cell tray 12, and at least one set of second baffle assemblies abuts against another cell tray 12.
[0054] The side baffle 162 can limit the side of the battery cell tray 12 during rotation, and can also position the battery cell tray 12 during installation.
[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
