Referring to fig. 1 to 5, the present invention provides a new energy vehicle battery post welding device 100, which includes a frame 110, a tray 120, a welding part, and a clamping assembly 130;
the tray 120 is movably connected with the frame 110, and the tray 120 is used for bearing the battery cover plate 10; the welding member is movably connected to the frame 110, and is used for welding the post 20 placed on the battery cover plate 10 to the battery cover plate 10;
the clamping assembly 130 comprises a bearing table 131 and a clamping arm 132; the bearing table 131 is connected with the frame 110, and the bearing table 131 is used for placing the tray 120; the holding arm 132 is movably connected to the frame 110 and is used to abut against the post 20 on the battery cover plate 10 to press the post 20 against the battery cover plate 10;
here, when the weld member rotates around the central axis of the pole 20 to perform the annular welding of the pole 20, the clamp arm 132 rotates around the central axis of the pole 20 in synchronization with the weld member.
It should be noted that, in this embodiment, firstly, since the battery cover plate 10 is provided with the positive and negative poles 20, the new energy vehicle battery pole welding device 100 includes two clamping arms 132, the two clamping arms 132 are respectively used for clamping the positive and negative poles 20, and the two clamping arms 132 are relatively located at two ends of the bearing platform 131 along the direction in which the tray 120 moves relative to the frame 110; the connecting position of the clamping assembly 130 and the rack 110 is a welding station for welding the pole 20 by the new energy automobile battery pole welding device 100, and the tray 120 is movably connected with the rack 110, so that the battery cover plate 10 can be driven to move towards the welding station or the battery cover plate 10 can be driven to be separated from the welding station along the moving direction of the tray 120 relative to the rack 110, namely, the support plate can supplement materials to the welding station and can also perform the blanking function from the welding station in the moving process;
next, the welding member is not shown in the form of the drawings, and in the present embodiment, the welding member may adopt a welding structure in the related art, which is capable of welding the post 20 on the battery cover plate 10 located in the above-described welding station during operation, and performs ring welding of the post 20 by rotating the welding member with respect to the post 20 during welding.
In addition, in the embodiment, when the clamping arm 132 in the clamping assembly 130 is provided, the clamping arm 132 plays a role in clamping the pole 20 and a role in abdicating the welded part in the process of welding the pole 20; therefore, when the holding arm 132 is installed, the holding arm 132 needs to be movably connected to the frame 110, so that the position of the holding arm 132 relative to the platform 131 can be changed by the movement of the frame 110 relative to the frame 110, and further, the holding arm 132 can move in a direction approaching the platform 131 and abut against the post 20 on the battery cover plate 10, so that the post 20 can be pressed against the battery cover plate 10 and the battery cover plate 10 can be pressed against the platform 131; when the pole 20 is welded in a ring shape by a welding part rotating relative to the pole 20, the clamping arm 132 can rotate relative to the frame 110, and because the clamping arm 132 needs to be kept in a state of abutting against the pole 20 when the pole 20 is welded by the welding part, the axis of the clamping arm 132 rotating relative to the frame 110 can be consistent with the central axis of the pole 20, and further, the position of the pole 20 welded by the welding part is different from the position of the clamping arm 132 by such a mode, and the relative position between the clamping arm 132 and the welding part can be adjusted by the rotation of the clamping arm 132 when the welding part rotates relative to the pole 20, so that the clamping arm 132 can be prevented from interfering with the movement of the welding part, and further, the welding efficiency can be improved and the welding quality can be improved;
it should be further noted that, in this embodiment, in the process of welding the terminal post 20, the clamping arm 132 needs to apply a certain clamping force to the terminal post 20 and the battery cover plate 10, and in order to avoid the battery cover plate 10 from deforming under the clamping force, therefore, in the process of clamping the battery cover plate 10, what is adopted is a manner of placing the tray 120 on which the battery cover plate 10 is placed on the bearing table 131, so that the supporting force for the battery cover plate 10 can be increased through the bearing table 131, and further, the battery cover plate 10 can be prevented from deforming in the processes of clamping and welding. Specifically, in the present embodiment, to increase the stability of the support, a plurality of support blocks 133 are disposed at intervals on the bearing table 131 along the direction in which the tray 120 moves relative to the frame 110, and the plurality of support blocks 133 are all used for surface contact with the tray 120.
