[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] like Figure 1 , Figure 2 As shown, this utility model discloses an automatic coil turning device. The technical solution includes a turning device 100 and a feeding platform 200, which are positioned correspondingly. The turning device 100 includes a base frame 1, with a guide rail frame on the top surface of the base frame 1. Two sets of patterned plates are laid on the top surface of the guide rail frame, forming a sliding groove 6 between the two sets of patterned plates. A track 7 is inside the guide rail frame. One side of the base frame 1 has a motor base plate and a reducer base plate, which are connected to the reducer base plate. A drive wheel seat is bolted to the reducer base plate, and a driven wheel seat is bolted to the other side of the base frame 1. A drive sprocket 3 is connected to the upper shaft of the drive wheel seat, and a driven sprocket 5 is connected to the upper shaft of the driven wheel seat. A reducer is also bolted to the reducer base plate, and a servo motor is bolted to the motor base plate. The output shaft of the servo motor is keyed to the input end of the reducer, and the reducer output shaft 4 is keyed to the drive sprocket 3. A chain is fitted between the drive sprocket 3 and the driven sprocket 5.

[0017] Track 7 has a flipping mechanism 2, such as Figure 3 As shown, the flipping mechanism 2 includes a main frame 201. The main frame 201 has two shafts connecting a movable wheel 208 and a guide wheel 209. The movable wheel 208 has a horizontal axis and sits on the track 7. The guide wheel 209 has a vertical axis and is connected to the inner wall of the guide rail frame. The movable wheel 208 can move along the track 7, while the guide wheel 209 can maintain the stability of the flipping mechanism 2 during movement. The main frame 201 is bolted to a vertically upward-facing support 202. A pressure rod 204 is axially connected to the upper end of the support 202. The hinge point between the pressure rod 204 and the support 202 is located at a non-end position of the pressure rod 204. A first hydraulic cylinder 203 controls the movement of the pressure rod 204. The cylinder body of the first hydraulic cylinder 203 is axially connected to the support 202, and the piston rod end is axially connected to the end of the pressure rod 204. A rotating seat 213 is also axially connected to the end of the pressure rod 204 away from the first hydraulic cylinder 203. When the pressure rod 204 is horizontal, the seat surface of the rotating seat 213 faces vertically downwards, and a polyurethane buffer pad is installed on the seat surface. The first hydraulic cylinder 203 is connected to a downward-pressing hydraulic circuit control system.

[0018] To accommodate coils 300 with different outer diameters, two sliding plates are bolted to the main frame 201. These two sliding plates are longitudinally mounted on the main frame 201, and longitudinal tracks are formed on their opposing surfaces. A lifting plate 206 slides within these tracks. A beam is bolted between the two sliding plates, and a second hydraulic cylinder 205 is bolted to the beam. The piston rod of the second hydraulic cylinder 205 is bolted to the lifting plate 206. A crossbeam 211 is bolted to the lifting plate 206. A mounting plate 212, a V-shaped plate, is welded to the crossbeam 211, and a rotating assembly 207 is attached to its top surface. Figure 4 As shown, the rotating assembly 207 includes a support frame 2074, which is bolted to the mounting plate 212. The support frame 2074 has a through hole, and a rotating cylinder 210 is bolted to its bottom surface. The rotating shaft of the rotating cylinder 210 passes through the through hole, and the outer ring of a support bearing 2073 is interference-fitted to the inner wall of the through hole. The inner ring of the support bearing 2073 is interference-fitted to the rotating shaft of the rotating cylinder 210. A bracket 2072 is keyed to the rotating shaft of the rotating cylinder 210. A buffer pad 2071, made of polyurethane, is bolted to the top surface of the bracket 2072. The buffer pad 2071 has a countersunk hole, and the countersunk head of the mounting bolt is located in the countersunk hole to prevent scratching or damaging the copper pipe. The rotating cylinder 210 is connected to a rotating hydraulic circuit control system, and the second hydraulic cylinder 205 is connected to a lifting hydraulic circuit control system.

[0019] like Figure 5 , Figure 6 As shown, the unloading platform 200 includes a base plate 21 with bolt holes for fixing to the ground with anchor bolts. A base 22 is welded to the base plate 21, and a tilting seat 23 is shaft-connected to the base 22. A material platform 24 is mounted on the tilting seat 23. The tilting action of the tilting seat 23 is driven by a third hydraulic cylinder 25. The cylinder shaft of the third hydraulic cylinder 25 is connected to the base 22, and the piston rod is connected to the shaft of the tilting seat 23. When the third hydraulic cylinder 25 extends, it can make the material platform 24 horizontal; when the third hydraulic cylinder 25 retracts, it can make the material platform 24 vertical. In order to provide stable support for the tilting seat 23 at both working positions, the base 22 is also equipped with... There are two support positions: a first support position 28 and a second support position 29. The two support positions have identical structures. Taking the first support position 28 as an example, it includes a through-tube with an integrally formed fixing plate. The fixing plate is mounted on the base 22 by fixing bolts. A support bolt passes through the through-tube, and two positioning nuts engage with the support bolt. The two positioning nuts are located at both ends of the through-tube, clamping the through-tube to position the support bolt. When the material platform 24 is in a horizontal state, the base 22 sits on the countersunk head of the support bolt in the first support position 28. When the material platform 24 is in a vertical state, the base 22 sits on the countersunk head of the support bolt in the second support position 29. The third hydraulic cylinder 25 is connected to the first tilting hydraulic oil circuit control system.

[0020] To transfer the coil 300 from the tilting device 100 to the material platform 24, the material platform 24 is an annular plate with a circular outer shape and a square inner shape. A support plate 27 is shaft-connected to the inner square hole. The change in the working position of the support plate 27 is driven by a fourth hydraulic cylinder 26. The cylinder body of the fourth hydraulic cylinder 26 is shaft-connected to the base 22, and the piston rod is shaft-connected to the support plate 27. The fourth hydraulic cylinder 26 is connected to a second tilting hydraulic circuit control system. A polyurethane buffer pad is provided on the support plate 27. The slide groove 6 of the flipping device 100 is equipped with a first proximity switch and a second proximity switch. When the flipping mechanism 2 moves to the first proximity switch, the rotating component 207 reaches directly below the coil 300 after winding. When the flipping mechanism 2 moves to the second proximity switch, the coil 300 corresponds to the position of the tray 27.

[0021] like Figure 8 As shown, it also includes a PLC controller, which is electrically connected to a host computer, a servo controller, a first proximity switch, a second proximity switch, a downward hydraulic circuit control system, a rotary hydraulic circuit control system, a lifting hydraulic circuit control system, a first tilting hydraulic circuit control system, a second tilting hydraulic circuit control system, and a communication module.

[0022] The working principle of this utility model: After the copper tube is coiled into coil 300, the control device of the front winding process sends a signal to the PLC controller communication module. The PLC controller drives the servo motor through the servo controller. After the servo motor is decelerated by the reducer, it drives the drive sprocket 3 to rotate. Then, it moves the flipping mechanism 2 towards coil 300 through the chain traction. When the flipping mechanism 2 moves, it moves along the track 7 through the moving wheel 208 to reduce the moving friction. The guide wheel 209 ensures that the movement of the flipping mechanism 2 does not deviate. When the PLC controller receives the electrical signal from the first proximity switch, it stops the servo motor. At this time, the rotating assembly 207 is located below the coil 300. The PLC controller controls the lifting hydraulic circuit control system and the pressing hydraulic circuit control system to operate, causing the second hydraulic cylinder 205 to extend and lift the rotating assembly 207, so that its buffer pad 2071 contacts the lower part of the coil 300. At the same time, the first hydraulic cylinder 203 extends, the pressure rod 204 presses down, and the rotating seat 213 presses against the upper part of the coil 300. The rotating assembly 207 and the rotating seat 213 together clamp the coil 300. Figure 7 As shown.

[0023] The PLC controller controls the first tilting hydraulic circuit control system to shorten the third hydraulic cylinder 25 and tilting seat 23 to tilt 90 degrees until the material platform 24 is vertical. At this time, the tilting seat 23 is connected to the support bolt of the second support position 29.

[0024] The PLC controller drives the servo motor to reverse through the servo controller. The flipping mechanism 2 moves towards the lower material table 200. When it leaves the winding station but has not yet reached the unloading table 200, it continues to move if flipping is not required according to the process requirements. If flipping is required, the PLC controller controls the rotary hydraulic circuit control system to drive the rotary cylinder 210 to drive the rotary component 207 to rotate. The rotary seat 213 follows the rotation, causing the coil 300 to rotate 180 degrees.

[0025] When the PLC controller receives the electrical signal from the second proximity switch, it stops the servo motor and controls the second tilting hydraulic circuit control system to activate the fourth hydraulic cylinder 26, pushing out the pallet 27. The pallet 27 rotates 90 degrees and flips out from the inner ring of the coil 300. The PLC controller controls the lifting hydraulic circuit control system and the pressing hydraulic circuit control system to reverse their actions, causing the rotating component 207 to descend, the pressure rod 204 to move onto the platform, and the coil 300 to be released. Under the action of gravity, the coil 300 falls onto the polyurethane buffer pad of the pallet 27. The PLC controller controls the first tilting hydraulic circuit control system to activate the third hydraulic cylinder 25, causing the tilting seat 23 to tilt 90 degrees until the platform 24 is horizontal. At this time, the tilting seat 23 is connected to the support bolt of the first support position 28, and the coil 300 falls onto the platform 24 under the action of gravity.

[0026] The PLC controller controls the second tilting hydraulic circuit control system to activate the fourth hydraulic cylinder 26, retracting the pallet 27 until it is level with the material table 24. This completes the unloading process.
