[0030] like Figure 1-7As shown, an automatic casing feeding winding machine includes a winding machine body, the winding machine body includes a frame 1, a mounting plate 2 is fixedly installed in the frame, a reducer 3 is fixedly installed on the mounting plate, the input shaft of the reducer 31 is fixedly connected to the output shaft of the first servo motor 4, the output shaft of the reducer is fixedly connected to the linear slide 5, two linear sliders 6 are slidably matched on the linear slide, the linear slider is fixedly connected to the mounting frame 8 through a cushion block 7, and a wire mold (not shown) is fixedly installed on the mounting frame; it also includes a position adjustment structure for driving the two wire molds to move closer or farther from each other; a moving structure is installed on the mounting plate, and the moving structure is used to drive the pipe feeding assembly 9 to move;

[0031] The pipe delivery assembly includes a pipe delivery support 10, which is sequentially provided with a copper wire guiding structure, a sleeve limiting structure and a sleeve shaping structure, and the sleeve shaping structure is arranged close to the wire mold.

[0032] In this way, before winding, according to the winding requirements, the distance between the two wire dies is adjusted through the position adjustment structure, the linear slide rail, the linear slider and the pad are set to provide a guide for the movement of the wire die and provide an installation basis for the wire die, and the wire die is fixedly connected to the mounting frame by screws, which is convenient for disassembly and replacement; then, after the copper wire passes through the copper wire guide structure, the sleeve is sleeved on the outside of the copper wire, and the sleeve is located between the sleeve limiting structure and the copper wire guide structure. After the sleeve passes through the sleeve shaping structure, it is wound with the copper wire, and the first servo motor is started, and the linear slide rail is driven to rotate through the output shaft of the reducer, thereby realizing the rotation of the two wire dies, so that the copper wire is wound on the wire die;

[0033] When the sleeve needs to be wound at a specified position of the copper wire, the sleeve limiting structure releases the limit, the sleeve closest to the wire mold abuts against the sleeve shaping structure, the sleeve limiting structure is reset, and the sleeve located at the rear is limited, and then the sleeve shaping structure bends the sleeve and the copper wire. When the copper wire is wound, the sleeve moves along the copper wire and is fixed at the bend of the copper wire to achieve a unified position of the sleeve, and then the sleeve shaping structure is reset;

[0034] During the winding process, the moving structure drives the feeding tube assembly to move back and forth to realize the winding of the copper wire on the wire die;

[0035] After the winding is completed, the position adjustment structure drives the two wire dies closer to each other, and then the operator removes the wound copper wire. The position adjustment structure drives the two wire dies to reset, and then the next winding can be carried out.

[0036] During implementation, the position adjustment structure includes a second servo motor 11 fixedly mounted on a mounting plate, a connecting rod 12 being fixedly mounted on the output shaft of the second servo motor, a through hole being provided through the output shaft of the reducer for allowing the connecting rod to pass through, a first bevel gear 13 being fixedly mounted on the end of the connecting rod away from the second servo motor, a connecting seat 14 being fixedly mounted on the linear slide rail, a forward and reverse screw 15 being mounted on the connecting seat through a bearing, the threads of the forward and reverse screws on both sides of the connecting seat being left-handed and right-handed respectively, a second bevel gear 16 meshing with the first bevel gear being fixedly mounted on the forward and reverse screws, and nuts threadedly connected to the two ends of the forward and reverse screws being mounted on the two pads respectively.

[0037] In this way, the second servo motor drives the connecting rod to rotate, the connecting rod passes through the through hole of the output shaft of the reducer, drives the second bevel gear and the forward and reverse screws to rotate through the first bevel gear, and drives the two pads to move closer or farther away from each other through the forward and reverse screws, thereby realizing the position adjustment of the two wire dies.

[0038] During implementation, a counter 18 is fixedly mounted on the output shaft of the reducer, so as to count the number of rotations of the output shaft of the reducer.

[0039] During implementation, the moving structure includes a third servo motor 19 fixedly mounted on a mounting plate and a moving guide rail 20, a moving slider 21 slidingly fitted on the moving guide rail, a nut block 22 fixedly mounted on the moving slider, the output shaft of the third servo motor is fixedly connected to one end of a one-way screw 23 through a coupling, the end of the one-way screw away from the output shaft of the third servo motor is fixedly connected to the guide rail block through a bearing, the guide rail block is fixedly mounted on the guide rail, the nut block is threadedly connected to the one-way screw, a moving rod 24 is fixed to the upper end of the nut block, and the moving rod is fixedly connected to a pipe delivery support.

[0040] In this way, the third servo motor drives the one-way screw to rotate, the moving guide rail and the moving slider provide a 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, and then drives the pipe delivery bracket to move. The setting of the guide rail block provides stable support for the end of the one-way screw.

[0041] During implementation, the pipe delivery support should be tilted downwardly close to the line mold. The tilted pipe delivery support allows the casing to abut against the casing limit structure under its own weight, which facilitates the delivery of the casing.

[0042] During implementation, the copper wire guiding structure includes a guide frame 25, on which three guide wheels 26 are rotatably mounted, and a conveying channel is formed between two adjacent guide wheels. The provision of two conveying channels facilitates improving efficiency.

[0043] During implementation, it also includes a wire pressing structure 27, which includes a wire pressing bracket, on which a V-shaped groove opening upward is provided, a rotating arm is rotated on one side of the wire pressing bracket, a wire pressing screw is threadedly connected to the rotating arm, a wire pressing block is fixed at the lower end of the wire pressing screw facing the V-shaped groove opening upward, and a clamping arm is rotated on the other side of the wire pressing bracket, and the clamping arm can be clamped with the rotating arm. The wire pressing bracket is used to tension the copper wire, which belongs to the existing structure. The copper wire passes through the V-shaped groove, and the wire pressing block is fixed with felt, which applies friction to the copper wire, so that the copper wire can be wound better.

[0044] During implementation, the casing limiting structure includes a limiting seat 28, which is slidably matched with the pipe delivery support. A clamping bolt (not shown) is also installed on the limiting seat. A limiting cylinder 29 is fixedly installed on the limiting seat. The cylinder rod of the limiting cylinder is downwardly arranged and fixedly installed with an upper limit block 30. A limiting arm 32 is fixed to the end of the upper limit block away from the casing shaping structure. A V-shaped groove opening downward is formed at the lower end of the limiting arm. The top end of the V-shaped groove opening downward is located below the upper limit block. A lower limit block 33 is fixedly installed on the limiting seat, and the lower limit block is arranged directly below the upper limit block.

[0045] In this way, the position of the limit seat and the tube delivery bracket is fixed by the compression bolt after sliding into place, so as to adjust the distance between the limit seat and the casing shaping structure to adapt to casings of different lengths, and the limit arm blocks the casing. When the casing needs to be delivered, the cylinder rod of the limit cylinder shrinks, the casing abuts against the casing shaping structure, and then the cylinder rod of the limit cylinder is reset to compress and limit the rear casing.

[0046] During implementation, the casing shaping structure includes a shaping frame 34 fixedly connected to the pipe delivery support, on which a shaping cylinder 35, an upper cylinder 36 and a lower cylinder 37 are fixedly installed, the cylinder rod of the shaping cylinder is arranged upward and fixed with an upper support block 38, and a limiting block 39 is fixedly installed on the shaping frame, the cylinder rod of the upper cylinder and the cylinder rod of the lower cylinder are arranged opposite to each other and are respectively fixedly installed with an upper block 40 and a connecting plate 42, and the connecting plate 42 is fixedly installed with a lower block 41 opposite to the upper block 40, and guide frames 43 are fixed on both sides of the connecting plate, and the guide frames are provided with guide grooves, and the upper end openings of the guide grooves are inclined outwards.

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

[0048] In the initial state, the cylinder rods of the upper cylinder and the lower cylinder are in an extended state, the upper block and the lower block limit the copper wire, and the sleeve is abutted against the lower block. When the sleeve is needed, the cylinder rod of the shaping cylinder is extended to drive the upper support block to move upward. Due to the setting of the limit block, the sleeve and the copper wire can be bent. Afterwards, the cylinder rod of the shaping cylinder, the cylinder rod of the lower cylinder and the cylinder rod of the upper cylinder are contracted at the same time. During the copper wire winding process, the sleeve is wound on the wire mold synchronously with the copper wire; afterward, the cylinder rods of the upper cylinder and the lower cylinder are extended and reset to continue to limit the copper wire.

[0049] When implemented, it also includes a protection structure, which is arranged on one side of the winding machine body and includes a protection frame 45. A clearance opening is opened on the side of the protection frame away from the winding machine body, and a safety grating 46 is fixedly installed on the protection frame to improve operation safety.

[0050] Specifically, the delivery pipe 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 through hole of the output shaft of the reducer, and drives the second bevel gear and the forward and reverse screws to rotate through the first bevel gear, and drives the two pads to move closer or farther from each other through the forward and reverse screws to adjust the positions of the two wire dies;

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

[0054] 3. The first servo motor drives the linear guide rail to rotate through the reducer, and then drives the two wire dies to rotate. At the same time, the third servo motor drives the one-way screw to rotate. The mobile guide rail and the mobile slider provide an installation basis for the nut block and limit the rotation of the nut block. The movement of the nut block drives the movement of the moving rod, and then drives the movement of the pipe delivery bracket. The pipe delivery bracket drives the copper wire to move, so that the copper wire is wound in the wire groove of the wire die in sequence;

[0055] 4. When the casing needs to be moved, the specific operations are as follows:

[0056] 4.1. According to the length of the casing, adjust the position of the limit seat relative to the pipe delivery support so that the distance between the lower limit block and the lower block is greater than the length of a single casing and less than 1.5 times the length of a single casing, and fix the limit seat on the pipe delivery support by tightening the bolts;

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

[0058] 4.3. When the casing is needed, first the cylinder rod of the limiting cylinder contracts, driving the limiting arm to move upward. Due to the inclined setting of the pipe delivery support, when the copper wire moves, the casing moves to abut against the lower block, and then the cylinder rod of the limiting cylinder extends, driving the upper limit block and the limiting arm to move downward, and the upper limit block and the lower limit block clamp and limit the casing located at the rear; then, the cylinder rod of the shaping cylinder extends upward, driving the upper support block to move upward, and the upper support block and the limiting block are staggered, so that the copper wire and the casing can be bent synchronously, so that when the copper wire moves, the casing can be driven to move synchronously; then, the cylinder rods of the upper cylinder, the lower cylinder and the shaping cylinder contract synchronously, and when the copper wire is wound, it drives the casing to move into place, completing the casing operation; finally, the cylinder rods of the upper cylinder and the lower cylinder extend and reset, so as to facilitate the next casing operation;

[0059] 5. After the winding is completed, the second servo motor drives the connecting rod to rotate in the opposite direction, and then drives the two wire dies closer to each other through the forward and reverse screws. The operator removes the wound copper wire, and then the second servo motor drives the two wire dies to reset, and then the next winding can be carried out.

[0060] Automatic pipe delivery is accomplished by the cooperation of 4 solenoid valves:

[0061] 1. The clamping solenoid valve cooperates with the limit cylinder to control the length of the casing. When multiple sections of casing are waiting, only one section is allowed to pass through each time (multiple sections within the range of 5-25 cm can be divided into multiple sections to the specified position);

[0062] 2. The shaping solenoid valve cooperates with the shaping cylinder. Its function is to make the copper wire and the casing move and bend at the same time before sending the casing so that the copper wire takes the casing away;

[0063] 3. The blocking solenoid valve and the sleeve releasing solenoid valve cooperate with the lower cylinder and the upper cylinder respectively, work and release at the same time, and leave enough space for the sleeve on the forward copper wire to pass smoothly.

[0064] Input numbers on the screen and start with one key. At the same time, the inward and outward movement distances are equal, which has the advantages of fast demoulding and accurate return to the original position. 18 slots can be set for sequential winding, plus 5, 6, 8, 9, 10 slots cross winding function, which solves the problem that the wire mold with a large middle and small ends cannot be demoulded.

[0065] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
