[0028] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0029] Example 1, see Figures 1 to 9 A coil production conveyor includes a stand 1, a controller is installed on the stand 1, and further includes:

[0030] A pre-lifting structure 2 connected to the stand 1, the pre-lifting structure 2 includes a rotating lifting mechanism 3 connected to the stand 1, a coil limiting mechanism 4 is installed on the rotating lifting mechanism 3, the rotating lifting mechanism 3 is used to adjust the height of the coil limiting mechanism 4, the coil limiting mechanism 4 is used to support the coil, and the rotating lifting mechanism 3 is connected to a locking mechanism 5, which is used to provide limiting protection for the rotating lifting mechanism 3;

[0031] The lifting and loading structure 6 is connected to the vertical frame 1, and the lifting and loading structure 6 includes two sets of rails 7 connected to the vertical frame 1, and a carrying trolley 8 is installed on the rails 7, and a wheel block is installed on the rails 7. The carrying trolley 8 is installed on the transporting trolley 8, and the height adjustment mechanism 9 is connected to a coil clamping mechanism 10 adapted to the pre-lifting structure 2.

[0032] When in use, the transport vehicle is parked at the lower part of the stand 1 and transports the coil to the coil limiting mechanism 4. The transport method can be selected as follows: the coil limiting mechanism 4 is set at the end of the assembly line to receive the coil, or a forklift is used for active transport. Then, the rotating lifting mechanism 3 is used to lift the coil limiting mechanism 4, and the locking mechanism 5 limits the rotating lifting mechanism 3 to prevent the rotating lifting mechanism 3 from accidentally falling. The transport trolley 8 on the track 7 drives the height adjustment mechanism 9 to move, and the height adjustment mechanism 9 drives the coil clamping mechanism 10 to move toward the coil limiting mechanism 4, and the coil clamping mechanism 1 0 performs a coil clamping operation, and the height adjustment mechanism 9 lifts the coil clamping mechanism 10, thereby allowing the coil to separate from the coil limiting mechanism 4. The carrying trolley 8 then drives the height adjustment mechanism 9 away from the coil limiting mechanism 4. Under the height adjustment mechanism 9, the coil clamping mechanism 10 is adjusted in height, and the coil clamping mechanism 10 places the coil on the carrying vehicle. During this period, the locking mechanism 5 releases the limit on the rotating lifting mechanism 3, and the rotating lifting mechanism 3 is reset, thereby allowing the lifting and loading structure 6 to perform the loading operation while the pre-lifting structure 2 preloads and lifts the next group of coils to be loaded. The present invention, through the cooperation between the pre-lifting structure 2 and the lifting and loading structure 6, allows the lifting and loading operations to be performed simultaneously, thereby improving the work efficiency of the present invention. By preventing the forklift from directly transporting the coils to the vehicle, the coil loading operation can be completed while the personnel are away from the coils and the loading vehicle. Even if the coils roll off, the safety of the personnel can be guaranteed, and the safety of the coils when they are transported to the vehicle can be improved.

[0033] In one case of this embodiment, the rotating and lifting mechanism 3 includes a frame 11 fixedly connected to the stand 1, the frame 11 fixedly connected to a base 12, two sets of parallel hinged plates 13 are hinged on both sides of the base 12, the hinged plates 13 are hinged together with a platform 14, the platform 14 is connected to the coil limiting mechanism 4, one set of hinged plates 13 is fixedly connected to a power-assisting frame 15, the power-assisting frame 15 is hinged with a second active telescopic rod 16 hinged to the frame 11, the second active telescopic rod 16 can be an electric telescopic rod or a hydraulic telescopic rod. The second active telescopic rod 16 pulls the power-assisting frame 15 to drive a set of hinged plates 13 to rotate, so that the hinged plates 13 drive the platform 14 to move, and the platform 14 drives the coil limiting mechanism 4, thereby adjusting the height of the coil limiting mechanism 4.

[0034] In one aspect of this embodiment, the coil limiting mechanism 4 includes a first motor 17 fixedly connected to the platform 14. The output shaft of the first motor 17 is fixedly connected to a V-shaped support platform 18, which is rotatably connected to the platform 14. The V-shaped support platform 18 is used to support the coil. The first motor 17 drives the V-shaped support platform 18 to rotate, thereby adjusting the orientation of the V-shaped support platform 18, thereby improving the convenience of loading the coil onto the V-shaped support platform 18.

[0035] In one case of this embodiment, the locking mechanism 5 includes an extension frame 19 fixedly connected to the platform 14, an L-shaped rod 20 is slidably installed on the extension frame 19, the L-shaped rod 20 is fixedly connected to a pressure plate 21, a first spring is installed between the pressure plate 21 and the extension frame 19, the first spring is ferromagnetic, and a first electromagnet 22 is fixedly installed at one end of the L-shaped rod 20, the L-shaped rod 20 is slidably connected to a hinge seat 23, the hinge seat 23 is rotatably connected to a bayonet frame 24 hinged to the extension frame 19, a bayonet 25 is provided on the bayonet frame 24, and an arc-shaped groove 26 is provided on the extension frame 19 that is slidably connected to the hinge seat 23, one group of the hinge plates 13 is installed with a card shaft 27 adapted to the card shaft 25, and the bayonet frame 24 is provided with an arc surface that matches the card shaft 27. When the hinge plate 13 is rotated and laid flat, the card shaft 27 squeezes the card frame 24, causing the card frame 24 to rotate and the hinge seat 23 to rotate accordingly. Under the pressure of the first spring on the pressure piece 21, the L-shaped rod 20 drives the hinge seat 23, causing the card frame 24 to return to its original position, so that the card slot 25 is engaged with the card shaft 27, thereby completing the limit of the hinge plate 13. The locking mechanism 5 is used to limit the hinge plate 13 when the hinge plate 13 is laid flat, thereby preventing the table 14 and the coil limiting mechanism 4 from performing a pendulum-like drop when an unexpected power outage occurs, protecting personnel safety. When the first electromagnet 22 magnetically attracts the first spring, the first spring contracts, and the first spring drives the L-shaped rod 20 through the pressure piece 21. The L-shaped rod 20 drives the card frame 24 to rotate through the hinge seat 23, so that the card slot 25 is separated from the card shaft 27, thereby releasing the limit of the hinge plate 13 by the locking mechanism 5.

[0036] In one aspect of this embodiment, the transport trolley 8 includes a body 28 on which four sets of wheels 29 are rotatably mounted. A power unit 30 is mounted on the body 28. The power unit 30 can be a servo motor or a stepper motor. The power unit 30 is connected to the two sets of wheels 29. The power unit 30 is specifically a second motor 31 fixedly connected to the body 28. The second motor 31 is connected to a transmission 32 connected to the body. The transmission 32 can be a continuously variable transmission or a stepped transmission. The output shaft of the transmission 32 is coaxially connected to the two sets of wheels 29. The body 28 is connected to the height adjustment mechanism 9. The power of the power unit 30 is transmitted to the two sets of wheels 29 through the transmission 32, thereby enabling the transport trolley 8 to move on the track 7.

[0037] In one aspect of this embodiment, the height adjustment mechanism 9 includes multiple sleeves 34 fixedly connected to the vehicle body 28. A first active telescopic rod 35 is fixedly mounted within the sleeves 34. The first active telescopic rod 35 can be an electric or hydraulic telescopic rod. A slide bar 36 slidably connected to the sleeves 34 is fixedly mounted at the movable end of the first active telescopic rod 35. The slide bar 36 is fixedly connected to the coil clamping mechanism 10. The first active telescopic rod 35 adjusts the height of the coil clamping mechanism 10 by driving the slide bar 36 to move.

[0038] In one aspect of this embodiment, the coil clamping mechanism 10 includes a clamping seat 37 fixedly connected to a slide bar 36. A dual-shaft motor 38 is fixedly mounted in the middle of the clamping seat 37. A screw 39 is fixedly connected to the output shaft of the dual-shaft motor 38. The screw 39 is threadedly connected to a clamping arm 40 that is slidably connected to the clamping seat 37. Driven by the dual-shaft motor 38, the screw 39 rotates, driving the clamping arms 40 to slide along grooves in the clamping seat 37, thereby adjusting the spacing between the clamping arms 40. The clamping arms 40 are used to clamp the coil.

[0039] Example 2, based on Example 1, refer to Figure 2 、 Figure 3 、 Figure 9 The platform 14 is fixedly connected to a chassis 41. The chassis 41 is rotatably connected to a rotating shaft 42 coaxially connected to the wheel 29. The rotating shaft 42 is fixedly connected to a center disk 43. A second electromagnet 44 is installed in the chassis 41. The second electromagnet 44 is connected to a friction plate 45 via a second spring. The second spring is ferromagnetic. The friction plate 45 is slidably installed in the chassis 41. The base 12 is fixedly connected to a limit frame 46 that is compatible with the hinge plate 13. During normal operation, the second electromagnet 44 magnetically attracts the second spring, causing the friction plate 45 to separate from the center disk 43. Once a power outage occurs, the friction plate 45, pushed by the second spring, squeezes the center disk 43, thereby applying resistance to the rotating center disk 43, thereby reducing the return speed of the rotating lifting mechanism 3. Under the limitation of the hinge plate 13 by the limit frame 46, the rotating lifting mechanism 3 is prevented from swinging back and forth.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
