[0032] Due to the irregular structure of the motor coil, especially when welding the terminals and wiring harnesses of special-shaped motor coils, specific tooling fixtures are required for positioning. The existing tooling fixtures are unstable and can easily cause the coil to loosen, resulting in poor welding results. Since the coil terminals are small in size and the welding area is limited, inaccurate coil positioning can easily cause the welding position to shift, affecting product yield.

[0033] To solve the above technical problems, please refer to Figures 1 to 4 As shown, according to some embodiments of the present application, a special-shaped motor coil welding tool is provided, including a substrate 1, a contour seat 2, a support seat 3 and a clamping mechanism 4, the contour seat 2 is movably connected to the substrate 1, a coil 211 is installed on the contour seat 2, the support seat 3 is movably connected to the substrate 1, a bottom mold 31 and a stopper 32 are installed on the support seat 3, the bottom mold 31 is used to support the terminal 212 of the coil, one side of the terminal 212 abuts against the stopper 32, the terminal is limited by the clamping mechanism 4 and the stopper 32, and the wiring harness is abutted against the terminal for welding.

[0034] According to some embodiments of the present application, a clamping mechanism 4 is disposed on the substrate 1, and the clamping mechanism 4 includes a driving part and a clamping block 44. The driving part is transmission-connected to the clamping block 44, and the clamping block 44 is pressed against the terminal 212. Since the motor coil is a special-shaped part, the terminal of the coil is small in size, and the area available for clamping on the terminal is limited. According to the size of the wiring harness and the position of the special-shaped structure of the coil, damage to the protruding special-shaped structure on the end surface is avoided. A welding position is formed between the clamping block 44 and the stop block 32, and the wiring harness 5 is placed in the welding position for welding the terminal and the wiring harness into shape.

[0035] According to some embodiments of the present application, a pressing cylinder 23 is installed on the contour seat 2 , and the output end of the pressing cylinder 23 is connected to a pressing rod 24 .

[0036] Furthermore, the contour seat 2 is provided with a contour groove 21 and a through hole 22, a coil 211 is installed in the contour groove 21, an output end of the clamping cylinder 23 passes through the through hole 33 and is connected to a clamping rod 24, and the clamping rod 24 is used to clamp the coil 211 in the contour groove 21, so that the coil can be stably installed without loosening, thereby ensuring the stability of the coil terminal.

[0038] According to some embodiments of the present application, the clamping block 44 has a bent portion, which is used to abut against the terminal, and a welding position is formed between the bent portion and the stopper 32. Specifically, the bottom surface of the bent portion abuts against the terminal and is pressed against the terminal, and a welding position is formed between the side wall of the bent portion and the stopper, and is used to place the wiring harness, which can achieve accurate positioning of the terminal and the wiring harness to avoid deviation of the welding position of the terminal, thereby improving the welding effect and product yield.

[0039] According to some embodiments of the present application, the driving unit includes a first cylinder 41 and a second cylinder 42. The first cylinder 41 is installed on the substrate 1.

[0041] According to some embodiments of the present application, two electrically controlled valves 11 are installed on the substrate 1, and the two electrically controlled valves 11 are electrically connected to the first cylinder 41 and the second cylinder 42 respectively. The two electrically controlled valves 11 can control the output displacement of the first cylinder 41 and the second cylinder 42, thereby controlling the specific moving distance of the clamping block 44 in the up and down directions and the left and right directions, thereby improving the positioning accuracy.

Finally, place the wiring harness in the welding position for welding the wiring harness and the terminal.
