[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figures 1-4 This utility model provides a feeding and turning device for an automated spool production line, comprising: The frame support unit is used to support the overall load of the equipment. The frame support unit includes a fixed frame 1, a connecting frame 2, and a flipping bracket 3. The flipping bracket 3 is rotatably connected to the connecting frame 2 and is used to carry the wire reel for feeding and flipping. The spool clamping mechanism is mounted on the flip bracket 3 and is used to clamp both ends of the spool. The wire spool clamping mechanism includes clamping block 1 5, clamping block 2 6, and electric push rod 7; The center positioning mechanism includes a movable seat 4 and a positioning shaft 8, which is used to push the positioning shaft 8 into the inner hole of the wire reel to center the wire reel.

[0019] Both the fixed frame 1 and the tilting bracket 3 are equipped with columns and beams. Reinforcing ribs 9 are provided at the connection between the columns and beams to improve the torsional strength of the frame and prevent the beams from deforming during tilting.

[0020] Adjustable feet are welded to the four corners of the bottom of the fixed frame 1. A level is installed on the surface of the fixed frame 1 with an accuracy of 0.02mm / m. When installing the equipment, the level of the frame is adjusted by the feet to ensure that the horizontal error is ≤0.1mm / m, so as to prevent the frame from tilting and slipping when the coil is turned over.

[0021] Clamping blocks 5 and 6 are provided with two sets of arc-shaped edges corresponding to both ends of the coil. The arc between clamping blocks 5 and 6 matches the outer circle of the coil. The clamping claws are made of high-strength aluminum alloy, model 6061-T6, and a 5mm thick silicone buffer pad is attached to the inside to avoid damage to the surface of the coil during clamping. The clamping claws can adaptively adjust the clamping position according to the diameter of the coil. After clamping, the radial displacement of the coil is ≤0.1mm.

[0022] The inner wall of the flip bracket 3 is fixedly connected to a connecting seat 1 for mounting an electric push rod 7. The telescopic end of the electric push rod 7 is fixedly connected to a connecting seat 2 that is fixed to clamping block 1 5 and clamping block 2 6. The connecting seat 2 is horizontally slidably connected to the surface of the flip bracket 3. When the electric push rod 7 is activated, the distance between the two sets of clamping blocks 1 5 and clamping block 2 6 can be adjusted to clamp the edge of the coil.

[0023] Furthermore, a clamping detection component is set up, with a pressure sensor installed on the inside of the clamping jaws. The sensor has a range of 0-2000N and an accuracy of ±3N to detect the clamping force in real time. When the clamping force reaches a preset threshold, such as 1200N for a 500kg spool, a clamping signal is sent to the control unit to prevent over-clamping or under-clamping.

[0024] It also includes a flip drive unit, which is the core of the coil flip power, enabling precise flipping at any angle from 0 to 180°. It includes a flip spindle, which runs through the two vertical plates of the flip bracket 3, has a diameter of 100-140mm, and is made of 35CrMo material. One end of the spindle is fixed to the bearing seat of the flip bracket 3, and the other end is connected to the drive assembly. It adopts a two-stage reduction structure with a servo motor power of 5.5kW and a speed of 3000rpm, a planetary reducer with a reduction ratio of 1:40 and a harmonic reducer with a reduction ratio of 1:50. It is connected to the rotating spindle through a coupling. The rotating angular velocity can be adjusted from 0.3-3° / s, and the angle control accuracy is ±0.05°. It can achieve arbitrary angle stopping, such as 30°, 90° and 180°.

[0025] The flipping bracket 3 adopts a U-shaped steel plate structure with a thickness of 20mm. The two side uprights of the flipping bracket 3 are connected to the flipping main shaft through bearings. The bottom inner wall of the flipping bracket 3 is equipped with a crossbeam for rigid fixation to ensure no shaking during flipping. A guide rail 11 is fixedly connected to the lower surface of the flipping bracket 3. A sliding seat 10 is slidably connected through and limited by the guide rail 11. The sliding seat 10 is fixedly connected to the movable seat 4. The positioning shaft 8 is fixed on the movable seat 4 and corresponds to the center of the wire reel. The diameter of the positioning shaft 8 is 50-150mm, which is adapted to the inner hole of the wire reel. A telescopic electric cylinder is fixedly connected to the lower surface of the flipping bracket 3. The telescopic end of the telescopic electric cylinder is fixedly connected to the movable seat 4.

[0026] The working principle and usage process of this utility model are as follows: By fixing the adjustable feet at the bottom of the frame 1 and using the level on the surface, the level of the frame is adjusted to an error of ≤0.1mm / m to ensure the stability of the equipment reference. According to the specifications of the wire reel to be fed, such as diameter, inner hole size and weight, the parameters are set in the control unit, and the shaft diameter that matches the inner hole of the wire reel is selected, such as the inner hole of the wire reel is 80mm, and the corresponding positioning shaft 8 shaft diameter is 80mm. Check that the silicone buffer pad of the clamping block is intact, that the pressure sensor is zeroed, and that the rotating spindle bearing is properly lubricated to ensure that all components are fault-free. The reel is conveyed to the preset bearing position of the tilting bracket 3 by a conveying mechanism, such as a roller conveyor, to ensure that the reel is centered; The control unit sends a positioning start signal, the telescopic electric cylinder drives the moving seat 4 to slide along the guide rail 11, the positioning shaft 8 is slowly inserted into the inner hole of the wire spool until the positioning shaft 8 is completely in contact with the inner hole wall, the telescopic electric cylinder stops moving, and the positioning completion signal is fed back by the displacement sensor. After positioning is completed, the control unit triggers the electric push rod 7 to move, and the connecting seat 2 drives the clamping block 5 and clamping block 6 to move closer to both ends of the coil, and the silicone buffer pad first contacts the surface of the coil; The pressure sensor provides real-time feedback on the clamping force. When the value reaches a preset threshold, the control unit sends a clamping command, the electric push rod 7 stops extending and retracting, and the coil is fixed. At this point, the radial displacement of the coil is ≤0.1mm. After the operator confirms that the clamping is in place, click the flip start button on the control unit to start the servo motor of the flip drive unit. After two-stage reduction, the servo motor drives the flip spindle to rotate. The flip bracket 3 flips with the spindle at a set angular velocity, such as 1° / s. During the process, the control unit monitors the flip angle in real time. When the set angle of 90° is reached, the servo motor brakes precisely to stop the coil angle. Once the coil is flipped into place, subsequent mechanisms on the production line, such as robotic arms, can grab or transfer the coil to complete the loading and docking. After the spool is transferred, the control unit sends a release signal, the electric push rod 7 moves in the opposite direction, the clamping blocks 5 and 6 disengage from the spool, and at the same time the telescopic electric cylinder drives in the opposite direction, the positioning shaft 8 exits from the inner hole of the spool, and the moving seat 4 returns to the initial position. The servo motor rotates in the opposite direction, causing the flipping bracket 3 to return to its initial horizontal position of 0°, waiting for the next reel to be loaded. If the specifications of the next reel change, repeat the above steps; otherwise, proceed directly to the next feeding cycle.

[0027] If the pressure sensor detects that the clamping force is below the threshold or exceeds the upper limit, the control unit will issue an alarm signal. It is necessary to check whether the position of the clamping block is offset or whether the electric push rod 7 is faulty. After troubleshooting, re-clamp. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
