[0023] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Please refer to Figure 2 and Figure 3 This utility model provides a DC motor grounding terminal welding device 100, including a carrier frame 10, a spot welding machine 20, a clamping assembly 30, a pushing cylinder 40, and a feeding module 50. The carrier frame 10 is used to hold the DC motor 200. The welding head 21 of the spot welding machine 20 faces the DC motor 200. Specifically, in this embodiment, the welding head 21 is driven by the driving mechanism of the spot welding machine 20, which is not shown in the figure. In this embodiment, the type of driving mechanism of the spot welding machine 20 is not limited, and the spot welding machine 20 is prior art; its specific working principle will not be described in detail in this embodiment.

[0025] Please refer to Figure 6 The clamping assembly 30 includes a rotary motor 31 and a rotating shaft 32 disposed at the output end of the rotary motor 31. A receiving block 33 is slidably connected to the rotating shaft 32. The receiving block 33 is provided with a receiving groove 331. The rotary motor 31 is used to drive the grounding terminal 201 to rotate to correspond with the DC motor 200. Furthermore, a limiting part 3311 is provided on the groove wall of the receiving groove 331, which is used to limit the grounding terminal 201.

[0026] As a specific implementation, in order to achieve two states, namely, the receiving block 33 moves along the axial direction of the rotating shaft 32 and the rotating shaft 32 drives the receiving block 33 to rotate, the rotating shaft 32 and the receiving block 33 are connected by a guide key.

[0027] The receiving block 33 is connected to a movable cylinder 34, which drives the receiving groove 331 to align with the discharging groove 511 and drives the receiving block 33 to move to correspond with the DC motor 200. Specifically, in this embodiment, the clamping assembly 30 also includes a first support frame 35 for supporting the movable cylinder 34.

[0028] Please refer to Figure 2 and Figure 3 The feeding module 50 has an output plate 51 at its output end, and an output groove 511 on the output plate 51. The feeding module 50 is used to drive the grounding terminal 201 to move along the output groove 511. Specifically, in this embodiment, the feeding module 50 is a linear vibrator.

[0029] Please refer to Figure 3 and Figure 4 The output end of the pusher cylinder 40 is provided with a pusher block 41. The pusher cylinder 40 is used to drive the pusher block 41 to push the grounding terminal 201 to slide into the receiving groove 331.

[0030] As one specific implementation, the DC motor grounding terminal welding device 100 also includes a second support frame 60 for supporting the pusher cylinder 40.

[0031] By setting up corresponding receiving blocks 33 and discharging blocks, as well as pushing cylinders 40 and moving cylinders 34, the grounding terminal 201 is pushed from the discharging groove 511 into the receiving groove 331 in sequence. Then, the receiving block 33 is driven by the rotary motor 31 to rotate the grounding terminal 201 to the state corresponding to the DC motor 200, thereby facilitating the welding of the grounding terminal 201.

[0032] For further details, please refer to Figure 3 and Figure 4 The DC motor grounding terminal welding device 100 also includes a guide cylinder 70, which is fixedly connected to the second support frame 60. The output end of the guide cylinder 70 is provided with a guide block 71, and the guide block 71 is provided with a guide groove 711. The guide cylinder 70 is used to drive the guide groove 711 to move between the discharge trough 511 and the receiving trough 331, and to correspond with the discharge trough 511 and the receiving trough 331. The guide block 71 guides the grounding terminal 201 as it moves from the discharge trough 511 to the receiving trough 331, thereby improving the accuracy of the grounding terminal 201's movement.

[0033] Please refer to Figure 3Before welding, the feeding module 50 delivers the horizontally positioned grounding terminal 201 to the end of the discharge slot 511 of the discharge plate 51. The guide cylinder 70 and the moving cylinder 34 respectively drive the guide groove 711 on the guide block 71 and the receiving slot 331 on the receiving block 33 to align. At this time, the receiving slot 331 and the guide groove 711 correspond. The pushing cylinder 40 drives the pushing block 41 to slide the grounding terminal 201 sequentially through the discharge slot 511 and the guide groove 711 into the receiving slot 331. Then, the rotary motor 31 drives the receiving block 33 to rotate the receiving terminal to a vertical position, i.e., as shown in the image. Figure 1 As shown, the vertically positioned grounding terminal 201 is eventually moved to correspond with the welding head 21 of the spot welding machine 20 by the moving cylinder 34, so that the welding head 21 of the spot welding machine 20 can move to weld the grounding terminal 201.

[0034] For further details, please refer to Figure 5 The guide groove 711 includes a first groove 7111 and a second groove 7112 that are interconnected. The width of the first groove 7111 is smaller than the width of the grounding terminal 201, and the width of the second groove 7112 is adapted to the width of the grounding terminal 201.

[0035] For further details, please refer to Figure 6 The output end of the moving cylinder 34 is provided with a limiting bracket 341 slidably connected to the rotating shaft 32. The limiting bracket 341 has a limiting groove 3411, and the receiving block 33 is located in the limiting groove 3411. Specifically, the limiting bracket 341 is U-shaped in general, and a through hole 3412 adapted to the rotating shaft 32 is opened on the limiting bracket 341. The rotating shaft 32 is embedded in the through hole 3412. The groove wall of the limiting groove 3411 is in contact with both ends of the receiving block 33 in the width direction. The output end of the moving cylinder 34 drives the receiving block 33 to move along the axial direction of the rotating shaft 32 through the limiting bracket 341.
