[0019] Please see Figures 1 to 4The present invention provides an embodiment of an automatic coil welding device, which includes a base 1, a support platform 2, a spot welder 3, a motor 4, a turntable 5, a positioning component 6, and a pushing component 7. The support platform 2 is disposed on one side of the upper surface of the base 1, the motor 4 is mounted and fixed on the other side of the upper surface of the base 1, the spot welder 3 is mounted and fixed on the top of the support platform 2, the turntable 5 is disposed on the top of the output end of the motor 4, the positioning component 6 is located on the top of the turntable 5, and the pushing component 7 is disposed on the bottom of the turntable 5. The positioning component 6 includes a positioning frame 61, a connecting groove 62, a square groove 63, a spring 64, and a silicone plate 65. The positioning frame 61 is fixed on the upper surface of the turntable 5. The positioning frames 61 are arranged in a circular array with the turntable 5 as the center. The positioning frame 61 is a hollow structure with an inner opening. The connecting groove 62 is opened in the middle of the positioning frame 61. The square groove 63 is opened at the bottom of the positioning frame 61. The spring 64 is fixed inside the positioning frame 61. The silicone plate 65 is fixed on the surface of the spring 64 and is located inside the connecting groove 62.

[0020] The base 1 serves as the foundation for the entire device, providing a mounting base and stability for all components. The support platform 2 is mounted on the base 1 to support and fix the spot welding machine 3. The spot welding machine 3 is the executor of the welding function. When the coil rotates to its lower position with the turntable 5, the welding torch of the spot welding machine 3 presses down to complete the welding. The motor 4 drives the turntable 5 to rotate. The surface of the turntable 5 integrates positioning components 6 and pushing components 7. By rotating, the coil is sequentially transported to the welding station and other auxiliary stations. The hollow structure with an opening on the inner side of the positioning frame 61 can accommodate the coil body and limit its radial displacement. The connecting groove 62 cooperates with the silicone plate 65 to form a flexible clamping channel, allowing slight deformation of the coil to adapt to coils of different diameters. The square groove 63 prevents the coil from sagging or sliding laterally due to its own weight, ensuring axial positioning stability. The spring 64 pushes the silicone plate 65 with elastic force to always keep it in contact with the outer wall of the coil, compensating for the coil size tolerance and achieving adaptive clamping. The soft material of the silicone plate 65 protects the coil insulation layer from damage and enhances friction to prevent slippage.

[0021] The pusher 7 includes a first movable groove 71 and a second movable groove 72. The first movable groove 71 and the second movable groove 72 are opened inside the turntable 5, and the first movable groove 71 and the second movable groove 72 are arranged in a circle with the turntable 5 as the center. The first movable groove 71 and the second movable groove 72 are respectively on the same horizontal line as the two sets of silicone plates 65 inside the positioning frame 61.

[0022] The first movable groove 71 and the second movable groove 72 respectively guide the horizontal movement of the connecting plate 79 and the connecting column 75.

[0023] A mounting plate 73 is fixed to the lower surface of the turntable 5, and a first linear guide rail 74 is fixed to the surface of the mounting plate 73. The first linear guide rail 74 is located at the bottom of the second movable groove 72.

[0024] Mounting plate 73 is used to support and install the first linear guide rail 74 and the second linear guide rail 76. The first linear guide rail 74 is responsible for driving the connecting column 75 to move.

[0025] A connecting post 75 is fixed on the upper surface of the slider of the first linear guide 74. The connecting post 75 is located inside the second movable groove 72 and is used to hold one end of the coil.

[0026] A second linear guide rail 76 is also fixed to the surface of the mounting plate 73, and the second linear guide rail 76 is located at the bottom of the first movable groove 71.

[0027] The second linear guide 76 is responsible for driving the horizontal movement of the electric push rod 77.

[0028] An electric push rod 77 is mounted and fixed on the upper surface of the slider of the second linear guide 76.

[0029] The electric push rod 77 serves two purposes: first, it drives the connecting block 78 and the connecting plate 79 to move vertically; second, it cooperates with the second linear guide rail 76 to move horizontally.

[0030] A connecting block 78 is fixedly installed at the output end of the electric push rod 77. The connecting block 78 is located inside the first movable groove 71, and a connecting plate 79 is fixed on the upper surface of the connecting block 78.

[0031] The connecting block 78 is a component that connects the electric push rod 77 and the connecting plate 79. The connecting plate 79 directly contacts the end of the coil, thereby confining the coil to the desired position.

[0032] Working principle: When the coil needs to be welded, the coil is first guided to the top of the turntable 5 by the conveying mechanism. Then, the first linear guide rail 74 pushes the connecting column 75 to move linearly inside the second movable groove 72. During this process, the coil is in contact with the silicone plate 65, and the coil moves more flexibly and reliably under the action of the spring 64. The square groove 63 prevents the coil from being unable to move inside the positioning frame 61. Then, the electric push rod 77 pushes the connecting block 78 to move upward, so that the connecting plate 79 is exposed from inside the first movable groove 71. Under the action of the second linear guide rail 76, the electric push rod 77 is pushed to move horizontally, and then the connecting plate 79 moves inside the first movable groove 71, thereby completing the fixation of the other end of the coil. Then, the turntable 5 drives the coil to the bottom of the spot welding machine 3, and the gun head of the spot welding machine 3 moves downward to realize the welding work of the coil.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
