[0035] After the winding is completed, the position adjusting structure drives the two wire forms to approach each other, then an operator takes down the wound copper wire, the position adjusting structure drives the two wire forms to reset, and the next winding can be performed.

[0036] In implementation, the position adjusting structure comprises a second servo motor 11 fixedly installed on the mounting plate, an output shaft of the second servo motor is fixedly connected with a connecting rod 12, the output shaft of the speed reducer is provided with a through hole allowing the connecting rod to pass through, and an end of the connecting rod away from the second servo motor is fixedly installed with a first bevel gear 13; the linear slide rail is fixedly installed with a connecting seat 14, the connecting seat is installed with a reversible lead screw 15 through a bearing, the reversible lead screw is provided with left and right threads on two sides of the connecting seat; the reversible lead screw is fixedly installed with a second bevel gear 16 meshing with the first bevel gear; and two pads are respectively installed with nuts threadedly connected with two ends of the reversible lead screw.

[0038] In implementation, the output shaft of the speed reducer is fixedly installed with a counter 18, so as to facilitate counting of the number of rotations of the output shaft of the speed reducer.

[0039] In implementation, the moving structure comprises a third servo motor 19 and a moving guide rail 20 fixedly installed on the mounting plate, the moving guide rail is slidably connected with a moving block 21, the moving block is fixedly installed with a nut block 22, an output shaft of the third servo motor is fixedly connected with one end of a unidirectional screw rod 23 through a shaft coupling, one end of the unidirectional screw rod away from the output shaft of the third servo motor is fixedly connected with a guide block through a bearing, the guide block is fixedly installed on the guide rail, the nut block is threadedly connected with the unidirectional screw rod, an upper end of the nut block is fixedly installed with a moving rod 24, and the moving rod is fixedly connected with a pipe feeding support.

The guide block is provided to provide stable support for the end of the unidirectional screw rod.

[0041] In implementation, the pipe feeding support is downwardly inclined to the direction close to the wire die. The inclined pipe feeding support allows the sleeve to abut against the sleeve limiting structure under the self weight, so as to facilitate transportation of the sleeve.

[0042] In implementation, the copper wire guide structure comprises a guide frame 25, three guide wheels 26 are rotatably installed on the guide frame, and a conveying channel is formed between two adjacent guide wheels. The two conveying channels are provided to facilitate improvement of efficiency.

[0043] In implementation, the wire pressing structure 27 further comprises a wire pressing support with an upward V-shaped slot, a rotating arm on one side of the wire pressing support, a wire pressing screw threadedly connected to the rotating arm, a wire pressing block fixed to the lower end of the wire pressing screw and opposite to the upward V-shaped slot, a clamping arm rotating on the other side of the wire pressing support, and the clamping arm capable of being clamped with the rotating arm. The wire pressing support is used for tensioning the copper wire, and belongs to the prior art. The copper wire passes through the V-shaped slot, and the wire pressing block is fixed with a felt to apply friction to the copper wire, so that the copper wire is better wound.

[0044] In implementation, the sleeve limiting structure comprises a limiting seat 28 slidably connected with the pipe feeding support, a compression bolt (not shown) mounted on the limiting seat, a limiting cylinder 29 fixedly installed on the limiting seat, a cylinder rod of the limiting cylinder downwardly arranged and fixedly installed with an upper limiting block 30, a limiting arm 32 fixed to the end of the upper limiting block away from the sleeve shaping structure, a downward V-shaped slot formed at the lower end of the limiting arm, a top end of the downward V-shaped slot located below the upper limiting block, a lower limiting block 33 fixedly installed on the limiting seat and oppositely arranged below the upper limiting block.

[0045] In this way, the limiting seat and the pipe feeding support are slidably connected, and after being slid into position, the compression bolt fixes the positions of the limiting seat and the pipe feeding support, so as to facilitate adjustment of the distance between the limiting seat and the sleeve shaping structure to adapt to sleeves of different lengths, and the limiting arm blocks the sleeve. When the sleeve needs to be fed, the cylinder rod of the limiting cylinder is retracted, the sleeve abuts against the sleeve shaping structure, and then the cylinder rod of the limiting cylinder is reset to compress and limit the sleeve on the rear side.

[0046] In implementation, the sleeve shaping structure comprises a shaping frame 34 fixedly connected with the pipe feeding support, a shaping cylinder 35, an upper cylinder 36 and a lower cylinder 37 fixedly installed on the shaping frame, a cylinder rod of the shaping cylinder upwardly arranged and fixed with an upper supporting block 38, a limiting block 39 fixedly installed on the shaping frame, an upper block 40 and a connecting plate 42 fixedly installed on the cylinder rod of the upper cylinder and the cylinder rod of the lower cylinder respectively, a lower block 41 fixedly installed on the connecting plate 42 opposite to the upper block 40, guide frames 43 fixed to the two sides of the connecting plate, guide grooves formed in the guide frames, and the upper ends of the guide grooves outwardly and obliquely opened.

[0047] In this way, in order to better move the sleeve along with the copper wire, the cylinder rod of the shaping cylinder is extended to drive the upper supporting block to move upward, and due to the arrangement of the limiting block, the sleeve and the copper wire can be bent.

[0048] Initially, the cylinder rods of the upper and lower cylinders are extended, and the upper and lower blocks limit the copper wire. The sleeve abuts against the lower block. When the sleeve is needed, the cylinder rod of the shaping cylinder extends, driving the upper support block to move upward. Due to the setting of the limiting block, the sleeve and copper wire can bend. Then, the cylinder rods of the shaping cylinder, the lower cylinder, and the upper cylinder retract simultaneously. During the copper wire winding process, the sleeve is wound synchronously on the mold with the copper wire. Afterward, the cylinder rods of the upper and lower cylinders extend and reset, continuing to limit the copper wire.

[0049] In practice, a protective structure is also included, which is located on one side of the winding machine body. The protective structure includes a protective frame 45, with a clearance opening on the side of the protective frame away from the winding machine body. A safety light curtain 46 is fixedly installed on the protective frame, thereby improving operational safety.

[0050] Specifically, the pipe delivery assembly also includes a protective cover.

[0051] The specific operation includes the following steps:

[0052] 1. Before winding, according to the winding requirements, the second servo motor drives the connecting rod to rotate. The connecting rod passes through the hole of the output shaft of the reducer and drives the second bevel gear and the positive and negative screw to rotate through the first bevel gear. The positive and negative screw drives the two pads to move closer or further apart, thereby adjusting the position of the two wire molds.

[0053] 2. Pass the copper wire through the conveying channel, put the sleeve on the copper wire, and then after the copper wire passes through the sleeve limiting structure and the sleeve shaping structure, it is fixed on one of the wire molds;

[0054] 3. The first servo motor drives the linear slide rail to rotate through the reducer, which in turn drives the two wire molds to rotate. At the same time, the third servo motor drives the unidirectional screw to rotate. The moving guide rail and the moving slider provide the mounting base for the nut block and limit the rotation of the nut block. The movement of the nut block drives the moving rod to move, which in turn drives the tube feeding bracket to move. The tube feeding bracket drives the copper wire to move, so that the copper wire is wound into the wire groove of the wire mold in sequence.

[0055] 4. When the sleeve needs to be moved, the specific operation is as follows:

[0056] 4.1. Adjust the position of the limiting seat relative to the pipe delivery support according to the length of the sleeve, so that the distance between the lower limiting block and the lower block is greater than the length of a single sleeve and less than 1.5 times the length of a single sleeve. Fix the limiting seat to the pipe delivery support with the locking bolt.

[0057] 4.2. In the initial state, the cylinder rod of the limiting cylinder is in the state of extending downward, the cylinder rods of the upper and lower cylinders are in the state of extending, the outer sides of the upper block and the lower block are wrapped with felt, the outer sides of the upper limiting block and the lower limiting block are wrapped with felt, and the copper wire passes between the upper limiting block and the lower limiting block and between the upper block and the lower block;

[0058] 4.3. When the sleeve is needed, first, the cylinder rod of the limiting cylinder is retracted, driving the limiting arm to move upward. Since the pipe feeding support is inclined, when the copper wire moves, the sleeve moves to abut against the lower block. Then, the cylinder rod of the limiting cylinder is extended, driving the upper limiting block and the limiting arm to move downward. The upper limiting block and the lower limiting block clamp and limit the sleeve located at the rear. Then, the cylinder rod of the shaping cylinder is extended upward, driving the upper supporting block to move upward. The upper supporting block is arranged in a staggered manner with the limiting block, so that the copper wire and the sleeve can be bent synchronously. In this way, when the copper wire moves, the sleeve can be driven to move synchronously. Then, the cylinder rods of the upper cylinder, the lower cylinder and the shaping cylinder are retracted synchronously. When the copper wire is wound, the sleeve is driven to move in place, and the sleeve setting operation is completed. Finally, the cylinder rods of the upper cylinder and the lower cylinder are extended to reset, so as to facilitate the next sleeve setting operation.

[0059] 5. After winding is completed, the second servo motor drives the connecting rod to reverse rotation, and then drives the two wire molds to move close to each other through the lead screw. The operator takes down the wound copper wire, and then the second servo motor drives the two wire molds to reset, so that the next winding can be performed.

[0060] The automatic pipe feeding is completed by cooperation of the four electromagnetic valves:

[0061] 1. The compression electromagnetic valve cooperates with the limiting cylinder, and the function is to control the length of the sleeve. When multiple sleeves are waiting, only one section is allowed to pass each time (5-25 cm range can be segmented to the specified position).

[0062] 2. The shaping electromagnetic valve cooperates with the shaping cylinder, and the function is to bend the copper wire and the sleeve simultaneously before the sleeve is fed, so that the copper wire drives the sleeve to move.

[0063] 3. The blocking electromagnetic valve and the sleeve releasing electromagnetic valve cooperate with the lower cylinder and the upper cylinder respectively, and work simultaneously and loosen. The copper wire leaves enough space for the sleeve to pass smoothly.

[0064] The screen input number one-key start moves inward and outward by equal distance, which has the advantages of rapid demolding and precise returning to the original position. The sequential winding can set 18 grooves, and add the cross winding functions of 5, 6, 8, 9 and 10 grooves, which solves the problem that the wire mold with large middle and small ends cannot be demolded.

[0065] It should be understood, however, that even though particular embodiments of the application have been disclosed, the application includes all modifications and equivalents of the methods and materials described. It is intended that the application cover any and all variations of the preferred embodiments of the application.
