[0002] The on-board charger is a device used to charge electric vehicles, and its main function is protection. The on-board charger is an accessory that allows digital products to be charged anytime and anywhere using the on-board power supply. It is widely used in the field of lithium battery charging for various portable and handheld devices, such as powering car batteries (12V for cars and 24V for trucks). The main function of the on-board charger is to connect the grid voltage to the on-board charger via the ground AC charging pile and AC charging port, thereby charging the electric battery. The control transformer composed of three connected skeletons is the core component of the on-board charger. Three coils are wound on the three skeletons respectively, and the two adjacent coils are connected to each other. The cross-line segments between the two adjacent skeletons need to be covered with Teflon tubes for isolation and protection. Since Teflon tubes need to be covered on the cross-line between the two skeletons, the traditional method is to manually cover the required number of Teflon tubes on the wire heads, and then manually push the Teflon tubes to position them on the cross-line segments during the winding process before automatic winding. The manual positioning of the Teflon tube (referred to as the sleeve) has the problems of inaccurate positioning, low positioning efficiency, high labor intensity of workers and high labor costs of enterprises.

The process of putting the wire through the casing and the process of transferring each section of the casing to the cross-line segment in the skeleton are all realized without manual operation, so that it can reduce the labor intensity of workers and reduce the labor cost of the enterprise. It effectively solves the traditional method of using manual operation to first put the required number of Teflon tubes on the wire head and then manually position the Teflon tubes on the cross-line segment of the skeleton during the skeleton winding process, resulting in inaccurate casing positioning, low casing positioning efficiency, high labor intensity of workers and high labor cost of the enterprise.

[0014] Through the above technical scheme, the wire is first passed through the first wire feeding tube, the second wire feeding tube, the third wire feeding tube and the fourth wire feeding tube in the first wire feeding assembly in sequence. When winding the wire, the first wire pressing cylinder pushes the first slide seat and then pushes the first wire pressing wheel to move in the direction of the damping wheel, so that the wire can be pressed onto the damping wheel. When the damping wheel rotates in the opposite direction to the wire feeding direction under the drive of the damper, it can provide resistance to the wire, so as to achieve tensioning of the wire, which improves the tightness and smoothness of the winding and ensures good quality of the winding. When it needs to feed or reel in the wire, the second wire pressing cylinder pushes the second slide and then jointly pushes the second wire pressing wheel and the third wire pressing wheel to move in the direction of the first wire feeding wheel and the second wire feeding wheel, and the second wire pressing wheel and the third wire pressing wheel can press the wire onto the first wire feeding wheel and the second wire feeding wheel respectively; when the wire feeding motor drives the second wire feeding wheel to rotate forward, the wire of the skeleton can be fed, and when the wire feeding motor drives the second wire feeding wheel to rotate reversely, the wire of the skeleton can be recovered (i.e., retracted or reeled in) and tensioned, so that it can realize automatic wire feeding and retracting or reeling in.

[0017] Through the above technical solution, the first sleeve push seat in the single sleeve threading assembly can move back and forth linearly along the first sleeve push sliding assembly under the drive of the first sleeve push cylinder, so that the first sleeve push tube can move forward and backward in the first sleeve reserve tube through the first sleeve push frame along with the movement of the first sleeve push seat; when the first sleeve push tube retreats a length of a sleeve (i.e., the first sleeve section) in the first sleeve reserve tube through the first sleeve push frame with the first sleeve push seat and driven by the first sleeve push cylinder, it can make room for the first sleeve section to be stored in the first sleeve reserve tube. The first sleeve section is transmitted from the port at the front end of the first sleeve reserve tube into the first sleeve reserve tube, and the wire can be automatically fed when each wire feeding wheel rotates under the drive of the wire feeding motor. When the wire is transported through the through hole in the first sleeve push tube and passes through the first sleeve section stored in the first sleeve reserve tube, the wire is threaded through the first sleeve section. When the first section of the casing needs to be transported with the wire, the first casing push cylinder drives the first casing push seat and then drives the first casing push tube to move forward to push out the first section of the casing stored in the first casing reserve tube, so that the first section of the casing can be transported with the wire.

[0019] Through the above technical scheme, the second sleeve pushing seat in the double sleeve threading assembly can reciprocate along the second sleeve pushing sliding assembly under the common drive of the second sleeve pushing cylinder and the third sleeve pushing cylinder, so that the second sleeve pushing tube can move forward and backward in the second sleeve reserve tube along with the movement of the second sleeve pushing seat through the second sleeve pushing rack; when the second sleeve pushing tube retreats in the second sleeve reserve tube by the sum of the lengths of two sections of sleeve (the second section of sleeve and the third section of sleeve) through the second sleeve pushing rack along with the second sleeve pushing seat and under the common drive of the second sleeve pushing cylinder and the third sleeve pushing cylinder, it can make room in the second sleeve reserve tube for the two sections of sleeve.

Since each wire feeding wheel can automatically feed the wire when driven by the wire feeding motor, the wire is transmitted through the through hole in the second casing push tube and passes through the two sections of casing stored in the second casing reserve tube, the casing of the wire is completed. When the casing section (i.e., two sections of casing) needs to be conveyed with the wire, the second casing pushing cylinder drives the second casing pushing seat and then drives the second casing pushing tube to move forward, so that the front section casing (the second section casing) stored in the second casing reserve tube can be pushed out from the front end port of the second casing reserve tube, so that the front section casing can be conveyed with the wire; similarly, when the third casing pushing cylinder drives the second casing pushing seat and then drives the second casing pushing tube to move forward, the rear section casing (the third section casing) stored in the second casing reserve tube can be pushed out from the front end port of the second casing reserve tube, so that the rear section casing can be conveyed with the wire, which realizes the automatic pushing and loading of the casing, and has the advantages of high work efficiency, good wire feeding and casing threading effect, and can reduce the labor intensity of workers and reduce the labor cost of the enterprise.

Since the wire is transported through the through hole of the first casing push tube and passes through the casing in the first casing reserve tube, the casing passing of the wire is completed. When the two casing positioning clamp fingers are closed, the wire through groove on each casing positioning clamp finger can form a through hole that only allows the wire to pass freely, and the two closed casing positioning clamp fingers can block the casing to prevent the casing from being brought out from the port at the front end of the first casing reserve tube as the wire is transported during the process of the wire passing through the casing; when the wire passes through the casing, the operation of the wire passing through the casing is completed. When the cross-line on the skeleton needs casing isolation, the casing clamp finger cylinder drives the two casing positioning clamp fingers to open, and each casing push tube is driven by the casing push cylinder connected to it to move toward the direction of the casing reserve tube opposite to it, and can push the casing out from the port at the front end of the casing reserve tube opposite to it. Then, the casing clamp finger cylinder drives the two casing positioning clamp fingers to close and clamp the casing, and under the joint drive of the first casing threading and feeding linear module, the casing feeding transverse linear module and the casing feeding lifting linear module, it can clamp the casing and slide it along the wire to the position where the cross-line segment on the skeleton needs casing isolation protection, so that it can automatically complete the positioning of the casing on the wire and automatically transmit the casing to the position where the cross-line on the skeleton needs casing isolation protection.

[0056] In one embodiment, the automatic Teflon tube wire feeding mechanism is used in conjunction with a winding machine for winding the frame, and the specific structure of the winding machine and its winding principle for the frame are common knowledge and will not be explained in detail here. The operating process of the automatic Teflon tube wire feeding mechanism is as follows: first, the wire is led into the first wire feeding assembly 7 through the first horizontal limiting wire assembly 6 and into the second wire feeding assembly 14 through the second horizontal limiting wire assembly 13. When the wire passes through the first horizontal limiting guide column 63 and the first horizontal limiting guide wheel 61 and the second horizontal limiting guide column 64 and the second horizontal limiting guide wheel 62 in each horizontal limiting wire assembly in turn, the first horizontal limiting guide column 63 in each horizontal limiting wire assembly presses the wire onto the first horizontal limiting guide wheel 61. Similarly, the second horizontal limiting guide column 64 presses the wire onto the second horizontal limiting guide wheel 62, so that the wire pay-off and transmission can be horizontally limited to prevent the wire from shaking in the horizontal direction, which ensures the constant wire feeding tension and thereby improves the quality of the skeleton winding.

[0057] When the wires are respectively transmitted from the first horizontal limit wire assembly 6 to the first wire feeding assembly 7 and from the second horizontal limit wire assembly 13 to the second wire feeding assembly 14, the wires transmitted from the first horizontal limit wire assembly 6 sequentially pass through the first wire feeding tube 705, the second wire feeding tube 706, the third wire feeding tube 707 and the fourth wire feeding tube 708 in the first wire feeding assembly 7 and are then transmitted to the single sleeve threading assembly 8; and the wires transmitted from the second horizontal limit wire assembly 13 sequentially pass through the first wire feeding tube 705, the second wire feeding tube 706, the third wire feeding tube 707 and the fourth wire feeding tube 708 in the second wire feeding assembly 14. The wire feeding tube 706, the third wire feeding tube 707 and the fourth wire feeding tube 708 are then transmitted to the double-tube threading assembly 15; the first wire pressing cylinder 7031 in each wire feeding assembly pushes the first wire pressing wheel 77 to move toward the damping wheel 74 through the first slide 703 to press the wire onto the damping wheel 74, and the damping wheel 74 can provide resistance to the wire when rotating under the drive of the damper 72, so as to achieve tensioning of the wire for skeleton winding, which improves the tightness and flatness of the skeleton when winding on the winding machine and ensures the good quality of the skeleton winding. When each wire feeding assembly needs to feed or reel in wire, the second wire pressing cylinder 73 in each wire feeding assembly jointly pushes the second wire pressing wheel 78 and the third wire pressing wheel 79 to move toward the direction of the first wire feeding wheel 75 and the second wire feeding wheel 76 respectively through the second slide 704, and the second wire pressing wheel 78 and the third wire pressing wheel 79 can press the wire onto the first wire feeding wheel 75 and the second wire feeding wheel 76 respectively; when the wire feeding motor 71 drives the second wire feeding wheel 76 to rotate forward, it can feed the wire for the skeleton winding, and when the wire feeding motor 71 drives the second wire feeding wheel 76 to rotate reversely, it can reel in (or withdraw) and tension the skeleton winding, so that it can automatically feed, withdraw or reel in wire. The first wire feeding tube 705, the second wire feeding tube 706, the third wire feeding tube 707 and the fourth wire feeding tube 708 are used to conduct the wires to prevent the wires from bending and deviating from the wire feeding path during the wire feeding process, thereby improving the constancy of the wire feeding tension and the quality of the skeleton winding.

[0058] When the wire is transmitted into the single-tube threading assembly 8 through the first wire feeding assembly 7, the first tube pushing seat 81 in the single-tube threading assembly 8 can move back and forth linearly along the first tube pushing sliding assembly 85 under the drive of the first tube pushing cylinder 86, so that the first tube pushing tube 83 can move forward and backward in the first tube reserve tube 87 along with the movement of the first tube pushing seat 81 through the first tube pushing frame 82; when the first tube pushing tube 83 retreats a distance of the length of a tube (i.e., the first section of tube) in the first tube reserve tube 87 through the first tube pushing frame 82 along with the first tube pushing seat 81 and driven by the first tube pushing cylinder 86, it can actually make room in the first tube reserve tube 87 for the first section of tube to be reserved. The first section of casing is transferred into the first casing reserve tube 87 from the port at the front end of the first casing reserve tube 87. When the second wire feeding wheel 76 rotates forwardly under the drive of the wire feeding motor 71, the wire can be automatically fed. When the wire is transferred through the through hole in the first casing push tube 83 and passes through the first section of casing stored in the first casing reserve tube 87, the wire is threaded through the first section of casing.

[0059] Similarly, when the wire is transmitted into the double-tube threading assembly 15 through the second wire feeding assembly 14, the second tube pushing seat 151 in the double-tube threading assembly 15 can reciprocate along the second tube pushing sliding assembly 155 under the joint drive of the second tube pushing cylinder 156 and the third tube pushing cylinder 157, so that the second tube pushing tube 153 can move forward and backward in the second tube reserve tube 1592 along with the movement of the second tube pushing seat 151 through the second tube pushing frame 152; when the second tube pushing tube 153 retreats in the second tube reserve tube 1592 by the sum of the lengths of the two sections of tube (i.e., the second section of tube and the third section of tube) through the second tube pushing frame 152 along with the second tube pushing seat 151 and under the joint drive of the second tube pushing cylinder 156 and the third tube pushing cylinder 157, it can actually make room in the second tube reserve tube 1592 for the two sections of tube to be stored. The two sections of casing are respectively transmitted into the second casing reserve tube 1592 from the port at the front end of the second casing reserve tube 1592 (the second section of casing transmitted into the front end of the second casing reserve tube 1592 is also called the front section of casing, and the third section of casing transmitted into the rear end of the second casing reserve tube 1592 is also called the rear section of casing); when the wire is transported through the through hole in the second casing push tube 153 under the joint action of each wire feeding wheel and the wire feeding motor 71 and passes through the two sections of casing stored in the second casing reserve tube 1592, the wire is threaded through the two sections of casing.

[0060] When the wire is passing through the casing, the casing positioning motor assembly 102 in each casing positioning assembly drives the casing clamp finger cylinder 106 to move to the port at the front end of each casing reserve tube through the casing positioning screw assembly 104. At the same time, the casing clamp finger cylinder 106 in each casing positioning assembly drives the two casing positioning clamp fingers 107 connected thereto to close, so as to tighten the port at the front end of each casing reserve tube and block the casing, so as to prevent the casing from being brought out from the port at the front end of each casing reserve tube as the wire is conveyed during the process of the wire passing through the casing.

[0061] When the cross-wire segment on the skeleton in the winding machine needs to be isolated by a sleeve, the sleeve clamp finger cylinder 106 in each sleeve positioning assembly drives the two sleeve positioning clamp fingers 107 to open; for example, when the first section of the sleeve needs to be transported with the wire, the first sleeve push cylinder 86 drives the first sleeve push seat 81 and then drives the first sleeve push tube 83 to move forward to push out the first section of the sleeve stored in the first sleeve reserve tube 87, so that the first section of the sleeve can be transported with the wire. When the sleeve section (i.e., two sections of the sleeve) needs to be transported with the wire, the second sleeve push cylinder 156 drives the second sleeve push seat 151 and then drives the second sleeve push tube 153 to move forward to push out the front section of the sleeve (the second section of the sleeve) stored in the second sleeve reserve tube 1592 from the front end port of the second sleeve reserve tube 1592, so that the front section of the sleeve can be transported with the wire. Similarly, when the third sleeve push cylinder 157 drives the second sleeve push seat 151 and then drives the second sleeve push tube 153 to move forward, the rear sleeve (third sleeve) stored in the second sleeve reserve tube 1592 can be pushed out from the front end port of the second sleeve reserve tube 1592, so that the rear sleeve can be transmitted with the wire. Then, the sleeve clamp finger cylinder 106 in each sleeve positioning assembly drives the two sleeve positioning clamp fingers 107 connected thereto to close and clamp the sleeve, and under the joint drive of the first sleeve threading and feeding linear module 11 and the sleeve threading and feeding displacement assembly 4, the sleeve can slide along the wire and be transmitted to the position where the cross-line segment on the skeleton needs sleeve isolation protection, so that the sleeve segment can be automatically positioned to the position where the cross-line segment on the skeleton needs sleeve isolation protection. At this time, the skeleton continues to wind the sleeve transmitted to the cross-line segment and winds it tightly at the position where the sleeve needs to be put on the skeleton, which makes the sleeve have the advantages of high positioning accuracy and good positioning effect.

[0062] In the wire blocking assembly 9, the baffle 95 can move back and forth along the wire blocking sliding assembly 93 through the baffle connecting rod 94 and driven by the wire blocking cylinder 92, and the baffle 95 can extend into or out of the skeleton in the winding machine when moving forward or backward, and the baffle 95 can move arbitrarily in the space under the joint drive of the first sleeve threading and wire feeding linear module 11 and the sleeve threading and wire feeding shifting assembly 4, and when the baffle 95 extends into the skeleton, it can block the winding of the skeleton, which ensures that the winding of the skeleton has the advantages of tight and neat winding, firm winding, high winding efficiency and good winding effect.

[0063] The overall structural design can realize the ability to feed two groups of wires separately, damp and tension the wires being fed, automatically pass the first section of the casing on one group of wires being fed, automatically pass the second section and the third section of the casing on the other group of wires being fed, automatically block the wires during winding of the skeleton, automatically withdraw the wires from the skeleton, and automatically transfer the first section, second section and third section of the casing that have been threaded to the positions in the cross-line section of the skeleton that need to be isolated and protected by the casing or to the positions in the skeleton that need to be isolated and protected by the casing, which ensures that the winding of the skeleton has good wire feeding effect, high wire feeding efficiency and high wire feeding tension. The invention has the advantages of constant force, high wire feeding accuracy, tight and smooth winding, high winding efficiency and good winding effect, and the process of threading the wire through the casing and transmitting each section of the casing to the cross-line segment in the skeleton can be achieved without manual operation, so that it can reduce the labor intensity of workers and reduce the labor cost of the enterprise, and effectively solves the traditional method of manual operation, which is to first put the required number of Teflon tubes on the wire head and then manually position the Teflon tubes on the cross-line segment of the skeleton during the skeleton winding process, resulting in inaccurate casing positioning, low casing positioning efficiency, high labor intensity of workers and high labor cost of the enterprise.
