Description

Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to a welding platform adapter plate positioning clamping claw mechanism. Background Art

[0002] The power battery generally includes a winding core, an electrolyte, a battery shell containing the winding core and the electrolyte, and a top cover assembled on the battery shell. When the winding core is assembled into the shell, the winding core and the adapter sheet need to be welded together by ultrasonic welding first, and then the adapter sheet and the top cover need to be welded together by laser welding.

[0003] However, the prior art is unable to fix the adapter during the adapter welding process, and the adapter will warp and shift under the action of external force. The adapter shift causes it to be misaligned with the pole, resulting in problems such as a crooked top cover, scrapped battery cells, or poor press-fitting into the shell. Utility Model Content

[0008] Furthermore, the outer side of the lower pressing block is also downwardly connected with a side limit block, and the side limit block abuts against the outer side of the adapter plate.

[0009] By adopting the above technical solution, the clamping claws can stably abut against the two sides of the adapter sheet to be welded, further preventing the adapter sheet from warping or deflecting under the action of external force.

[0012] Furthermore, a positioning hole is provided on the positioning plate, and the positioning hole corresponds to the moving space of the end side limit block when the clamping claw moves downward and opens to place the adapter plate.

[0013] By adopting the above technical solution, it is convenient for the clamping claw to move downward and open to place the adapter, thereby reducing the possibility of the adapter falling directly at a higher position and causing bouncing and deviation.

[0014] Furthermore, the said giving way holes are provided in a plurality, corresponding to different positions of the pressing block pressed on the adapter plate.

[0015] By adopting the above technical solution, it is convenient to weld different positions, especially to weld the adapter plates to different poles.

[0017] By adopting the above technical solution, the placement position of the battery is limited, making it easier to weld the adapter to the pole.

[0018] Furthermore, the battery limiting seat includes a limiting plate with three sides distributed in a U shape, and the battery is pushed or placed in the opening side of the limiting plate by a push plate or a robot.

[0019] By adopting the above technical solution, the limiting plate limits the placement position of the battery, the push plate or the manipulator pushes or places the battery, and pushes and limits the battery to the three-side limiting plates.

[0020] Furthermore, a lifting assembly is provided at the bottom of the battery limiting seat to drive it to move up and down so that the battery pole is close to or away from the welding position with the adapter.

[0021] By adopting the above technical solution, the battery is driven to rise and fall, so that the battery is pushed into the limiting plate at the lower position, and then the battery rises upward until its corresponding pole part is located in the corresponding contoured hole.

[0029] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation of the utility model. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] A welding platform adapter plate positioning clamping mechanism, such as Figure 1 As shown, it includes a positioning plate 1 and a positioning clamp 2, and a battery is placed under the positioning plate 1; Figure 2As shown, the positioning plate 1 is detachably connected to the machine body by screws, and can also be connected to a lifting mechanism to drive it to rise and fall; a plurality of through holes are provided on the positioning plate 1, and corresponding profiling sheets are detachably connected by screws, and profiling holes 11 are provided on the profiling sheets, and the bottom height of the profiling sheets is lower than or flush with the positioning plate 1, and the profiling holes 11 are adapted to the shape of the adapter sheet to be welded, so as to place the adapter sheet;

[0031] The positioning clamp 2 includes a clamping claw body 21 and a pneumatic / electric finger that drives the clamping claw body 21 to move closer to or away from each other. The clamping claw body 21 reciprocates between the profiling hole 11 and the loading position, and clamps the adapter on the loading position in turn and places it in the profiling hole 11. In this embodiment, the positioning clamp 2 is driven by multiple linear modules to move along three directions of XYZ (not shown in the figure) to achieve horizontal and vertical displacement. Its specific structure is existing technology and will not be described in detail here.

[0032] like Figure 2 and Figure 3 As shown, the outer end of the clamping claw body 21 is connected to the lower pressing block 22, and the lower pressing block 22 presses the adapter plate above the battery pole; the outer side of the lower pressing block 22 is also connected downward to a side limit block 23, and the side limit block 23 abuts against the outer side of the adapter plate to further prevent the adapter plate from warping or deflecting under the action of external force;

[0033] Correspondingly, the outer periphery of the contoured hole 11 of the positioning plate 1 is also connected with a clearance hole 12 for the side limit block 23 to be inserted downwardly, so as to facilitate the partial positioning and insertion of the side limit block 23; the clearance hole 12 is determined according to the welding position. For example, when the adapter is only welded on one pole, a pair of clearance holes 12 is set to facilitate subsequent connection through the adapter; when directly welded on two or more poles, a plurality of clearance holes 12 are provided, and the corresponding number and position are set according to the position of the pole, and the corresponding lower pressing block 22 is pressed on different positions of the adapter, and the corresponding welding positions are finally directly realized through the adapter to realize the series or parallel connection between the batteries.

[0034] like Figure 2 As shown, a positioning hole 13 is also provided on the positioning plate 1. The positioning hole 13 corresponds to the moving space of the side limit block 23 at the end of the clamping claw body 21 when it moves downward and opens to place the adapter. In this embodiment, the positioning hole 13 is in the shape of a long groove, and a pair of side limit blocks 23 are allowed to move inside the two ends of the positioning hole 13; the clamping claw body 21 moves downward to a position close to the contour piece and opens to place the adapter, thereby reducing the possibility of the adapter falling directly at a higher position and causing a bounce-up deviation, and its side limit block 23 can have space to enter to reduce interference.

[0035] like Figure 1As shown, a battery limiting seat 3 for placing the battery is provided below the positioning plate 1; specifically, the battery limiting seat 3 includes a limiting plate 31 with three sides being U-shaped, and the two sides of the limiting plate 31 are detachably connected to the top of the battery limiting seat 3 by bolts, etc., so as to facilitate replacement according to the battery size, and the battery is pushed in or placed by a push plate or a manipulator on the opening side of the limiting plate 31 (through holes can be provided on the outer sides of the limiting plates 31 on both sides to make way), and the pushed in or placed state is maintained until the welding is completed, and the pushed in or placed position is in the middle or upper part of the battery, which is convenient for the battery limiting seat 3 to be lifted and lowered; the limiting plate 31 can also be directly set to a rectangle, and the manipulator clamps the battery and moves it to the top of the limiting plate 31 and then puts it down, and then the manipulator can retract;

[0036] A lifting assembly is provided at the bottom of the battery limit seat 3 to drive it to move up and down so that the battery pole is close to or away from the welding position with the adapter. In this embodiment, the lifting assembly includes two symmetrically arranged lifting screws 32 and a plurality of lifting guide posts. The lifting screws 32 are threadedly connected to the battery limit seat 3, and the lifting guide posts guide the lifting of the battery limit seat 3.

[0037] The battery limit seat 3 limits the placement position of the battery. The placement position of the battery is limited by the limit plate 31. The push plate or manipulator pushes or places the battery, and pushes and limits the battery in the three-side limit plates 31; the lifting assembly drives the battery to lift, so that the battery is pushed into the limit plate 31 at the lower position, and then the battery rises upward until its corresponding pole part is located in the corresponding contoured hole 11.
