[0002] A pay-off reel is an automatic pay-off device for copper coils during the stamping of lead frames. A rotating shaft is provided on one side of the pay-off reel for connecting with the core of the copper coil, so that the copper coil moves synchronously with the rotating shaft, thereby realizing the automatic pay-off of the copper coil. When loading the copper coil, the output end of the hoisting equipment usually passes through the core of the copper coil, and the core of the copper coil is inserted onto the rotating shaft of the pay-off reel.
[0003] However, when the hoisting equipment hoists and rotates the copper coil, both sides of the connecting piece are vertically connected to the hoisting equipment along both sides of the copper coil. During the hoisting process, the outer ring of the copper coil is easily squeezed by the connecting piece, causing the outer ring copper coil to deform and resulting in material waste. In addition, when the core of the copper coil is inserted into the rotating shaft of the pay-off reel, it is inconvenient to remove the connecting piece, which affects the operation efficiency. Content of the Utility Model

Detailed implementation manners
[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0027] As Figures 1-7 shown, this embodiment provides a copper coil transfer device, including: a transfer cart 10 and a suction cup assembly 20 provided on the transfer cart 10.
[0028] Specifically, a lifting mechanism is provided on the transfer cart 10, and the output of the lifting mechanism is connected to one end of the connecting arm 11, so that the connecting arm 11 can move up or down along the height direction of the transfer cart 10. The cylinder 12 is rotatably connected to the connecting arm 11.
[0029] Specifically, as Figures 1-4 shown, the suction cup assembly 20 includes a suction cup 21, a set of connecting seats 22, a support 23, a gear ring 24, a gear 25, a motor 26, a positioning plate 27, and a mounting plate 28. A set of connecting seats 22 is provided on one side of the suction cup 21, and the set of connecting seats 22 are symmetrically located on both sides of a diameter of the suction cup 21 respectively. The end of the set of connecting seats 22 far from the transfer cart 10 is rotatably connected to the connecting arm 11. The support 23 is provided at one end of the diameter, and the output end of the cylinder 12 is rotatably connected to the support 23.
[0030] As Figures 4-7As shown in the figure, an annular groove 211 is recessed on the outer periphery of the suction cup 21. An annular strip 242 protrudes inward from the inner wall of the gear ring 24. The annular strip 242 is rotatably connected to the annular groove 211. The gear ring 24 is provided with waist-shaped holes 241 in a circumferential array. A positioning hole 212 is provided on the outer periphery of the suction cup 21. The length direction of the positioning hole 212 is set towards the center of the suction cup 21, and the positioning hole 212 is located below the annular groove 211. A positioning plate 27 is slidably arranged in the positioning hole 212. The positioning plate 27 has an inverted L-shaped structure. The vertical part of the positioning plate 27 is slidably connected to the positioning hole 212, and the horizontal part is vertically downward. A cambered surface is provided on the surface of the horizontal part facing the center of the suction cup 21, and a layer of rubber pad is covered on the cambered surface to avoid damaging the outer ring of the copper coil 1 and increase the friction with the copper coil 1 at the same time, so as to better fit the outer wall of the copper coil 1. One end of the positioning plate 27 is slidably connected to the waist-shaped hole 241.
[0031] The mounting plate 28 is mounted on one side of the suction cup 21. One end of the mounting plate 28 is vertically connected to one side of the suction cup 21, and the other end extends above the gear ring 24. The motor 26 is vertically mounted on the other end of the mounting plate 28, and the output end of the motor 26 vertically penetrates the other end of the mounting plate 28. The gear 25 is mounted on the output end of the motor 26, and the gear 25 meshes with the gear ring 24.
[0032] During use, start the transfer vehicle 10 to drive the suction cup 21 to move to the copper coil 1 to be transferred. Start the motor 26 to drive the gear 25 to rotate, thereby driving the gear ring 24 to rotate. The waist-shaped hole 241 on the gear ring 24 pushes the positioning plate 27 to slide along the positioning hole 212. The positioning plate 27 acts on the outer periphery of the copper coil 1. During the process of pressing the positioning plate 27 against the outer periphery of the copper coil 1, adjust the position of the moving vehicle 10, so that the center of the suction cup 21 is concentric with the center of the copper coil 1, so that the contact area between the suction cup 21 and the copper coil 1 is the largest when sucking the copper coil 1, and the force stability of the copper coil 1 during the transfer process is better.
[0033] After the suction cup 21 sucks the copper coil 1, start the lifting mechanism to drive the connecting arm 11 to move upward. At the same time, start the cylinder 12 to make the output end of the cylinder 12 move towards the transfer vehicle 10, so that the suction cup 21 drives the copper coil 1 from a horizontal state to a vertical state, and then move the copper coil 1 to one side of the unwinding machine, and insert the core of the copper coil 1 along the rotating shaft of the unwinding machine, thus completing the transfer of the copper coil 1.
[0034] Specifically, as Figures 1-3 shown in the figure, in order to avoid shaking during the transfer of the copper coil 1, the connecting arm 11 is set as a U-shaped structure. The outer ends of the two vertical parts on both sides are respectively rotatably connected to a set of connecting seats 22. A sliding seat 111 is provided on the horizontal part of the connecting arm 11. The sliding seat 111 is slidably connected to the transfer vehicle 10, so that the lifting mechanism drives the connecting arm 11 to move up or down through the sliding seat 111.
[0035] To increase the connection area between a set of connecting seats 22 and the suction cup 21, the set of connecting seats 22 is in an inverted T-shaped structure, and the length of the horizontal part of the set of connecting seats 22 is greater than its vertical part length. The bottom surface of the horizontal part of the set of connecting seats 22 is connected to one side of the suction cup 21, and the vertical part is connected to the outer end of the vertical part of the connecting arm 11, so that the connection between the set of connecting seats 22 and the suction cup 21 is more stable.
[0036] Specifically, as Figure 4 、 Figure 7 , a connecting pin 271 is rotatably provided above the connection between the vertical part and the horizontal part of the positioning plate 27. A limiting plate is provided after the upper end of the connecting pin 271 passes through the kidney-shaped hole 241, and the connecting pin 271 is rotationally matched with the kidney-shaped hole 241. Thus, the rotation of the gear ring 24 drives the synchronous movement of the kidney-shaped hole 241, so as to control the length of the positioning plate 27 extending out of the positioning hole 212 at different positions of the connecting pin 271 in the kidney-shaped hole 241 to adapt to the transfer of copper coils 1 of different sizes.
[0037] The above are only the preferred embodiments of the present invention and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
