[0043] The thin glue wrapping unit 6 includes a glue pulling hand 61 and a glue pulling drive 62 that drives it to move up and down inside and outside the magnetic ring. A retractable first glue pressing part 63 is provided on the outer side of the glue outlet nozzle 52, and a retractable second glue pressing part 64 is provided on the output end of the glue pulling drive 62.

[0044] In the present invention, the winding magnetic ring 100 is sent by the material transfer unit 2 to the wide glue wrapping unit to complete the wide glue wrapping, and then transferred to the fine glue wrapping unit 6 for wrapping, and then sent out, realizing the automatic wide glue and fine glue wrapping process of the winding magnetic ring, and realizing rapid automated production.

[0045] In a preferred embodiment of the present invention, the magnetic ring motion drive 21 includes a linear motion drive 211 and a rotation drive 212 provided at the output end of the linear motion drive, the opening and closing drive 221 of the magnetic ring clamping hand 22 is connected to the output end of the rotation drive 212, the material transfer unit 2 includes two magnetic ring motion drives 21 and two magnetic ring clamping hands 22, the two magnetic ring clamping hands 22 correspond to the wide rubber encapsulation station and the thin rubber wrapping station respectively, and the frame 1 is also provided with a material transfer manipulator 23 capable of grabbing the magnetic ring and moving between the two magnetic ring clamping hands 22. Each magnetic ring clamping hand 22 corresponds to a set of magnetic ring motion drives 21, which can realize the simultaneous operation of two stations, further improving the rubber encapsulation production efficiency.

[0046] In order to better position the magnetic ring for automated action, the frame 1 is provided with a magnetic ring positioning loading platform 7, which is provided with a concave wall 71 for accommodating the position of the positioning magnetic ring and a clearance groove 72 for the magnetic ring clamping hand 22 to enter and exit. The magnetic ring positioning loading platform 7 is connected to a lifting drive, which can be lifted and lowered to facilitate the magnetic ring clamping hand 22 to take the material. The concave wall 71 matches the outer periphery of the magnetic ring, and the clearance groove 72 matches the magnetic ring clamping hand 22, which can be quickly positioned when loading and transferring materials.

[0047] Furthermore, the wide glue clamping assembly 32 includes a wide glue discharge nozzle 321 and a wide glue clamping hand 322. The wide glue clamping hand 322 is provided with a glue clamping moving drive for driving it to move relative to the wide glue discharge nozzle 321 and an opening and closing drive for driving it to open and close. A guide roller 34 is provided between the wide glue discharge tray 31 and the wide glue discharge nozzle 321, and the wide glue cutting knife 33 is provided on one side of the wide glue discharge nozzle 321.

[0048] The wide rubber-coated unit in the present invention includes a plurality of rubber-coated push handles 4 , and the rubber-coated push piece 42 of each rubber-coated push handle 4 is rectangular or waist-shaped. The rubber-coated push piece 42 includes two oppositely arranged rubber-coated push arms 421 and an elastic piece sleeved on the outer periphery of the two rubber-coated push arms 421 .

[0049] In a preferred embodiment of the present invention, there are four rubber-wrapped pushers 4, and the long straight side of the rubber-wrapped pusher 42 of the main rubber-wrapped pusher 401 is consistent with the length direction of the wide tape, and is located on the back of the clamped wide tape, opposite to the end circumference of the magnetic ring. When the wide tape is clamped, the main rubber-wrapped pusher 401 on the back is driven to move to the end of the magnetic ring together with the wide tape, and then the main rubber-wrapped pusher 401 is driven by the independent movement to push the main rubber-wrapped pusher 401 to stick to the back of the wide tape and further stick it to the end face of the magnetic ring, and its rubber pushing surface 43 completely aligns the wide tape with the outer circumferential surface of the end of the magnetic ring. Fully covered, the wide adhesive cutter 33 cuts the wide adhesive tape. At this time, the width direction of the wide adhesive tape exceeds the upper and lower surfaces of the magnetic ring. The long straight sides of the other three rubber-wrapped pushers 4 are perpendicular to the length direction of the wide adhesive tape, and are respectively located on both sides and ends of the magnetic ring, called side rubber-wrapped pushers 402 and end rubber-wrapped pushers 403. Each rubber-wrapped pusher 4 moves and drives independently, and presses the wide adhesive tape against the outer periphery of the magnetic ring from the middle and both ends of the wide adhesive tape that is attached to the outer periphery of the magnetic ring, and at the same time, the edge of the wide adhesive tape that exceeds the upper and lower surfaces of the magnetic ring is attached to the enameled wire on the upper and lower surfaces of the winding magnetic ring. Of course, for the compactness of the structure, the two ends of the wide adhesive tape can be coated first, and then the middle part can be coated, or the middle part can be coated first and then the two ends, so that the wide adhesive coating process is smoother and more reasonable. After wrapping one end of the magnetic ring, the rotation drive 212 of the magnetic ring motion drive 21 drives the magnetic ring to rotate, so that the other end of the magnetic ring is opposite to the wide glue wrapping unit main element, and wide glue wrapping is carried out. After the wide glue wrapping is completed, the magnetic ring is sent to the fine glue wrapping unit 6 for fine glue wrapping.

[0050] The present invention is a preferred embodiment for wrapping the thin glue head end, the glue pulling hand 61 includes an inner glue pulling arm 611 and an outer glue pulling arm 612 that can be opened and closed, the relative clamping surfaces of the inner glue pulling arm 611 and the outer glue pulling arm 612 are staggered and matched to prevent the thin glue from slipping, the outer end of the glue pulling arm 612 has a convex arc portion 613 for pressing the end of the thin glue against the enameled wire on the outer side of the magnetic ring 100, the glue pulling drive 62 is preferably a two-dimensional linear motion drive, the glue pulling hand 61 can be extended and raised into the inner ring of the magnetic ring and docked with the glue outlet nozzle 52 to clamp the thin glue, and then the glue pulling hand 61 is lowered and retracted away from the inner ring of the magnetic ring, so that the thin glue is attached to the lower surface of the magnetic ring 100 and then extended, and then rises along the outer side surface of the magnetic ring 100, so that the back of the thin glue is attached to the convex arc portion 613, the glue pulling hand 61 continues to pull the thin glue up and the convex arc portion 613 simultaneously presses the thin glue to the outer side surface of the magnetic ring, to complete the wrapping of the thin glue head end, such as Figure 6-8 shown.

[0051] For the glue wrapping of the thin adhesive tape at the tail end of the present invention, the first glue pressing member 63 has an integrally formed glue pressing arc surface 631 and a glue pressing plane 632. When the first glue pressing member 63 moves to the outside of the magnetic ring, it is located between the magnetic ring and the glue outlet nozzle 52. The glue pressing arc surface 631 can press the thin adhesive tape on the enameled wire outside the magnetic ring and move along the length direction of the thin adhesive tape under the drive of the movement of the first glue pressing member 63. The thin adhesive cutting knife 53 is located on the other side of the glue outlet nozzle 52. The glue pressing plane 632 can press the thin adhesive tape against the enameled wire outside the magnetic ring. The glue outlet 52 tightens the thin tape to facilitate the thin tape cutter 53 to cut the thin tape. The first glue pressing piece 63 continues to move downward, and its glue pressing arc surface 631 presses the tail end of the thin tape against the back of the head end of the thin tape. The second glue pressing piece 64 has a smooth convex surface 641 opposite to the outer peripheral surface of the magnetic ring. Driven by its telescopic drive 640, the second glue pressing piece 64 extends out to contact the thin tape on the outer periphery of the magnetic ring, and is raised and lowered by the glue pulling hand drive 62 to press the thin tape. In order to further reduce the positioning precision of the automated action, the first glue pressing piece 63, the second glue pressing piece 64 and the convex arc portion 613 of the glue pulling hand 61 are all elastic or flexible parts, which can adhere to the tape without damaging the enameled wire on the magnetic ring. Preferably, the contact parts that contact the back of the tape and stick it to the enameled wire are all glue-planted to form a flexible glue pressing part.

[0052] For the motion drive of each structural unit, the goal is to improve the work efficiency of each drive, maximize the application of kinetic energy and simplify the structure. For example, multiple rubber-coated pushers 4 have separate telescopic drives and also share a total motion drive, shortening the drive stroke; the opening and closing drive and telescopic drive of the material transfer manipulator 23 are arranged on the material transfer drive 231 to achieve horizontal movement, and the base of the fine glue unloading unit 5 is also arranged on the material transfer drive 231 to reciprocate horizontally; the glue outlet nozzle 52, the fine glue cutter 53 and the first glue pressing part 63 share a lifting drive, which is slidably arranged on the material transfer drive 231; the glue pulling hand 61 and the second glue pressing part 64 share the glue pulling drive 62. The control system unit 200 controls the operation of each structural unit.

[0053] The working process of the rubber encapsulation of the present invention is as follows: the control system unit 200 is activated, the magnetic ring that has completed the winding is placed in the concave wall 71 of the magnetic ring positioning loading platform 7, the magnetic ring clamping hand 22 is moved to the bottom of the magnetic ring positioning loading platform 7 and is opposite to the give way groove 72, the magnetic ring clamping hand 22 is opened and located on both sides of the magnetic ring, the magnetic ring positioning loading platform 7 is lowered, so that the magnetic ring is located in the clamping position of the magnetic ring clamping hand 22, and then the magnetic ring clamping hand 22 is tightened to clamp the magnetic ring, the magnetic ring positioning loading platform 7 continues to descend, the magnetic ring clamping hand 22 moves to move the magnetic ring to the wide rubber encapsulation station, the arc-shaped outer periphery of the magnetic ring is opposite to the clamping position of the wide rubber clamping assembly 32, the head end of the wide tape is pre-clamped at the wide rubber discharge nozzle 321, the wide rubber clamping hand 322 moves to the wide rubber discharge nozzle 321, clamps the free end of the wide tape, and then retracts. The wide adhesive tape of a predetermined length is pulled out, and the adhesive surface of the wide adhesive tape is opposite to the magnetic ring. The main adhesive wrapping pusher 401 on the back of the wide adhesive tape moves so that its adhesive pushing surface 43 contacts the wide adhesive tape and pushes the wide adhesive tape to stick to the outer peripheral surface of the magnetic ring. In order to avoid pulling the adhesive too long during sticking, the wide adhesive feeding unit 3 moves together with the wide adhesive wrapping unit to be close to the magnetic ring, and the main adhesive wrapping pusher 401 is then pushed by its independent telescopic drive to stick the wide adhesive tape to the outer periphery of the magnetic ring 100, and the wide adhesive cutting knife 33 cuts the material, and the main adhesive wrapping pusher 401 retreats, and the side adhesive wrapping pushers 402 on both sides of the magnetic ring work to stick the two side edges of the two end portions of the wide adhesive tape to the upper and lower surfaces of the magnetic ring 100, and the side adhesive wrapping pushers 402 return to their positions, and the end adhesive wrapping pushers 403 work to stick the two side edges of the middle portion of the wide adhesive tape to the upper and lower surfaces of the magnetic ring 100, completing a The enameled wire at one end of the end magnetic ring is coated with wide glue, and the magnetic ring 100 is rotated so that its other end is in the coating station for the same wide glue coating. After the wide glue coating is completed, the material transfer robot 23 grabs the magnetic ring to the magnetic ring clamping hand 22 of the corresponding fine glue wrapping unit, and positions and clamps the magnetic ring for fine glue wrapping. The fine glue unloading unit 5 moves under the drive of the material transfer drive 231 so that the glue nozzle 52 is located above the inner periphery of the magnetic ring 100, and the end of the fine tape clamped by the glue nozzle 52 is downward, and the clamping part of the glue pulling hand 61 is opposite to the clamping part of the glue nozzle 52. The glue pulling drive 62 drives the glue pulling hand 61 to move to the bottom of the inner periphery of the magnetic ring 100, and then rises to dock with the glue nozzle 52 and clamp the end of the fine tape, and then pulls the fine tape downward to the bottom of the magnetic ring 100, and then moves to the outer periphery of the magnetic ring 100 and rises, and During the lifting process, the convex arc portion 613 of the glue pulling hand 61 is in contact with the enameled wire on the outer periphery of the magnetic ring, and at the same time, the end of the thin adhesive tape is loosened, and the thin adhesive tape is pulled from the inner periphery to the outer periphery of the magnetic ring, wrapped around the enameled wire, and the thin adhesive feeding unit 5 moves again to make the first glue pressing piece 63 be located at a position where its glue pressing arc surface 631 can be in contact with the enameled wire on the outer periphery of the magnetic ring. The first glue pressing piece 63 extends and descends to its glue pressing plane 632 to press against the back of the thin adhesive tape, and continues to descend until the thin adhesive tape bypasses the upper surface of the magnetic ring and partially adheres to the enameled wire on the outer periphery of the magnetic ring. At this time, the thin adhesive tape between the first glue pressing piece 63 and the glue outlet nozzle 52 is tightened, and the thin adhesive cutter 53 moves from the other side of the glue outlet nozzle 52 to cut off the thin adhesive tape. When the glue outlet nozzle 52 is loosened, the first glue pressing piece 63 continues to move downward to attach the tail end of the thin adhesive tape to the outer periphery of the magnetic ring.It is preferred to overlap or partially overlap with the head end of the thin tape, and finally the second glue pressing member 64 moves to its convex surface 641 to press the thin tape, further compressing the thin tape, and then rotating the magnetic ring clamping hand 22 to wrap the other end with glue. After the magnetic ring is wrapped with glue, it is sent to the magnetic ring positioning loading platform 7 at the unloading position for unloading, that is, the glue wrapping process of the winding magnetic ring is completed.
