[0044] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0045] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0046] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0048] It should be noted that the automatic winding machine C10 can be set on the RFID code chip automatic assembly equipment to perform winding processing on the coil of the RFID code chip, wherein the RFID code chip automatic assembly equipment can be sequentially provided with a PCB board loading station, a coil winding station, a welding station, a wire cutting station, a waste wire clamping station, etc., wherein the automatic winding machine C10 is set at the coil winding station for winding processing, and the carrier D10 after the winding processing is transferred to the next station for welding the coil and the PCB board, waste wire cutting processing and waste wire clamping processing, etc.

[0049] The embodiment of the present invention provides an automatic winding machine C10, such as Figures 1 to 9 As shown, it includes a carrier D10 and a winding device C1;

[0050] The carrier D10 includes a first carrier D1 and a second carrier D2; the first carrier D1 is provided with a first bearing part D11; the second carrier D2 is provided with a second bearing part D22, and the second carrier D2 is provided with a through hole D21, and the second carrier D2 can be detachably arranged on the first carrier D1; when the second carrier D2 is assembled on the first carrier D1, the first bearing part D11 of the first carrier D1 is passed through the through hole D21, and the second carrier D2 is provided with a first end column D26 and a second end column D27 at a side edge near the through hole D21; that is, the through hole D21 is arranged between the second bearing part D22 and the two end columns.

[0051] The second carrier D2 can be loaded on the winding device C1 , and the winding device C1 sequentially winds the first end column D26 , the second carrying portion D22 , and the second end column D27 of the second carrier D2 .

[0052] Specifically, when winding processing is required, the second carrier D2 is separated from the first carrier D1, and the second carrier D2 is transferred and loaded on the winding device C1. The winding device C1 performs winding processing on the first end column D26 of the second carrier D2, and fixes the wire end of the coil on the first end column D26. Then the winding device C1 performs winding processing on the second bearing part D22 of the second carrier D2 to form a coil. Finally, the winding device C1 performs winding processing on the second end column D27 of the second carrier D2, and fixes the wire tail end of the coil on the second end column D27. Then, the second carrier D2 after winding is completed is assembled on the first carrier D1 for the next step of other processes, such as subsequent PCB board welding and waste wire cutting after welding. Among them, by setting a structure of two end columns on one side of the second carrier D2, the wire head and tail ends of the coil can be led out and fixed. Combined with the structure that the second carrier D2 can be detachably placed on the first carrier D1, the first carrier D1 can carry a PCB board for soldering with the coil. Therefore, when the second carrier D2 is separated from the first carrier D1 for winding processing, the PCB board is not affected by the movement of the second carrier D2 and is still stably placed on the first carrier D1. When the winding of the second carrier D2 is completed, the second carrier D2 is placed back on the first carrier D1. At this time, the PCB board on the first carrying part D11 corresponds to the bottom of the wire head and tail ends on the coil, that is, the two copper wires of the coil span the PCB board, and the carrier D10 is further transferred to the welding station of the RFID code chip automatic assembly equipment. At this time, the welding device of the welding station can directly weld the PCB board on the carrier D10 and the wire head and tail ends of the coil, thereby welding the two copper wires of the wire head and tail on the coil to the PCB board. After welding is completed, it can be directly moved to the wire cutting station to cut off the excess copper wire on the two end columns, and then transferred to the waste wire clamping station to take out the waste copper wire cut off from the two end columns.

[0053] Therefore, the automatic winding machine C10 cooperates with the carrier D10 and the winding device C1, wherein the carrier D10 is provided with a detachable second carrier D2 on the first carrier D1, the second carrier D2 having a second bearing portion D22, a through hole D21 and two end posts, the first bearing portion D11 of the first carrier D1 is passed through the through hole D21 of the second carrier D2, and the winding device C1 can automatically wind the second carrier D2 to obtain a coil, wherein by providing a structure with two end posts on one side of the second carrier D2, the wire head and wire tail ends of the coil can be led out and fixed, after the winding of the second carrier D2 is completed, the wound second carrier D2 is placed back on the first carrier D1, at this time, the PCB board on the first bearing portion D11 can be just corresponding to the bottom of the wire head and wire tail ends on the coil, which is convenient for the subsequent welding of the PCB board with the wire head and wire tail ends of the coil, the cutting of the waste wire after welding, and the removal of the waste wire, thereby effectively improving the automation process of FRID code chip assembly.

[0054] In some embodiments, such as Figures 1 to 8 As shown, the automatic winding machine C10 includes a machine base 100 and a transfer device C2. The machine base 100 has a placement position 101 and a winding position 102. It should be noted that the placement position 101 is set on the workstation disk of the machine base 100. Specifically, the first carrier D1 is fixed on the placement position 101. When the carrier D10 is carried on the placement position 101 and transferred from the previous workstation to the winding device C1 of the coil winding workstation, the second carrier D2 is transferred from the placement position 101 to the winding position 102 for winding processing by the transfer device C2. After the winding processing, the second carrier D2 is transferred to the placement position 101 of the workbench and then transferred to the next workstation for other processing.

[0055] The winding position 102 is provided with a winding device C1; the transfer device C2 transfers the second carrier D2, and the transfer device C2 has a first position and a second position, the first position is set corresponding to the placement position 101, and the second position is set corresponding to the winding position 102.

[0056] Specifically, when winding processing is required, the second carrier D2 in the placement position 101 is transferred to the winding position 102 through the transfer device C2, and the winding device C1 performs winding processing on the first end column D26 of the second carrier D2, and fixes the wire head end of the coil on the first end column D26, and then the winding device C1 performs winding processing on the second bearing part D22 of the second carrier D2 to form a coil, and finally the winding device C1 performs winding processing on the second end column D27 of the second carrier D2, and fixes the wire tail end of the coil on the second end column D27, and then transported to the placement position 101 through the transfer device C2 for assembly with the first carrier D1 to perform the next step of other processes such as subsequent PCB board welding and waste wire cutting after welding.

[0057] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 As shown, the machine base 100 also has a heating position 103, and the heating position 103 is provided with a first heating device C3, and the winding position 102 is provided with a second heating device C4; the transfer device C2 has a third position, and the third position is provided corresponding to the heating position 103. When the transfer device C2 transfers the second carrier D2 to the heating position 103, the first heating device C3 heats the second bearing portion D22 of the second carrier D2. When the second carrier D2 reaches the winding position 102, the second heating device C4 performs secondary heating on the second bearing portion D22 of the second carrier D2, and the winding device C1 simultaneously winds the second carrier D2. Specifically, the transfer device C2 can move between the placement position 101, the heating position 103, and the winding position 102 to transfer the second carrier D2 to the placement position 101, the heating position 103, or the winding position 102. Among them, the existing automatic winding machine C10 usually adopts a single hot air structure to complete the heating in one go during the winding process. However, it is found that the operation of completing the heating in one go will cause the instantaneous temperature difference of the adhesive material of the coil to be too large. The adhesive material will produce internal stress due to rapid solidification, which will reduce the bonding strength. In addition, it takes a long time to heat to the preset temperature in one go. Therefore, in this embodiment, two heating devices are set up, wherein the first heating device C3 is set at the heating position 103, and the second heating device C4 is set at the winding position 102. The first heating device C3 can gradually heat the second carrier part D22 of the second carrier D2 from room temperature in a step-by-step heating mode, so that the second carrier part D22 is preliminarily preheated, and then the preheated second carrier D2 is transferred to the winding position 102 for winding operation. At the same time, the second heating device C4 continues to perform secondary heating in the winding synchronization stage to ensure the optimal melting fluidity of the adhesive material, while avoiding local overheating and improving the winding effect of the coil. When one second carrier D2 is preheated at the heating position 103, the winding position 102 can simultaneously perform secondary heating on the second carrier part D22 of another second carrier D2. The use of double-station alternating heating operation can effectively improve processing efficiency and improve heat utilization.

[0058] In some embodiments, two first heating devices C3 can be provided, and two heating positions 103 can be adapted to be provided on the machine base 100. Specifically, a heating position 103 can be provided at the loading position of the machine base 100 corresponding to the second carrier D2, and another heating position 103 can be provided on one side of the placement position 101. The two first heating devices C3 can be adapted to be provided on the two heating positions 103, so that the second carrier D2 can be heated three times by three heating devices, which can have a better heating effect, further reduce the heating time, and improve the processing efficiency.

[0059] In some embodiments, the first heating device C3 includes a first hot air blower; the first hot air blower is positioned on one side of the heating position 103, with its air outlet facing the heating position 103. The second heating device C4 includes a second hot air blower; the second hot air blower is positioned on one side of the winding position 102, with its air outlet facing the winding position 102. The hot air blower blows hot air toward the heating position 103 or the winding position 102, allowing the hot air to flow within the space, achieving non-contact heating and ensuring a more uniform temperature on the second carrier portion D22 of the second carrier D2.

[0060] In some embodiments, as Figure 3 and Figure 4As shown, the winding device C1 includes a power source device C11 and a first fixing part C12 and a second fixing part C13 connected to the power source device C11, a loading position is provided on the first fixing part C12, and the end of the second carrier D2 away from the second bearing part D22 can be detachably assembled at the loading position, and the second fixing part C13 has a third position and a fourth position. When the second fixing part C13 is in the third position, the second fixing part C13 abuts against the second bearing part D22 of the second carrier D2 assembled on the first fixing part C12, and when the second fixing part C13 is in the fourth position, the second fixing part C13 is detached from the second carrier D2 assembled on the first fixing part C12. When winding is required, the transfer device C2 transfers the second carrier D2 to the first fixed portion C12, and assembles the end of the second carrier D2 away from the second bearing portion D22 at the loading position on the first fixed portion C12. At this time, the second bearing portion D22 of the second carrier D2 extends out of the loading position of the first fixed portion C12, and the power source device C11 drives the first fixed portion C12 to move forward, backward, left, and right to wind the wire end around the first end column D26 of the second carrier D2. After the wire end is wound, the power source device C11 drives the second fixed portion C13 to move from the fourth position to the third position. At this time, the second fixed portion C13 abuts against the second bearing portion D22 of the second carrier D2, thereby abutting against the opposite ends of the second carrier D2 through the first fixed portion C12 and the second fixed portion C13. , so as to dynamically lock the second carrier D2 and limit the second bearing part D22 between the second carrier D2 and the second fixed part C13, so as to facilitate the winding process of the second bearing part D22. Subsequently, the power source device C11 drives the first fixed part C12 to rotate and the second fixed part C13 to move synchronously, so as to drive the second carrier D2 to rotate and perform the winding process on the second bearing part D22 of the second carrier D2 to obtain a coil. When the winding is completed, the second fixed part C13 moves from the third position to the fourth position. At this time, the second fixed part C13 is separated from the second carrier D2. Then, the power source device C11 drives the first fixed part C12 to move forward, backward, left and right to wind the tail end of the wire around the second end column D27 of the second carrier D2. Then, the wire is cut to obtain a coil structure with an annular ring and two lead-out end wires.

[0061] In some embodiments, as Figure 5 and Figure 6As shown, the loading position is a plurality of positioning columns C121 arranged at the end of the first fixing part C12, and the second carrier D2 is provided with a plurality of positioning holes adapted to the positioning columns C121. The second carrier D2 is assembled on the first fixing part C12 through the plug-in cooperation with the positioning columns C121 through the positioning holes, and the end of the first fixing part C12 is also provided with a magnetic part C122 that is magnetically attracted to the second carrier D2. The plug-in fit of the positioning posts C121 and the positioning holes allows the second carrier D2 to be quickly and accurately positioned on the first fixing portion C12, avoiding the misalignment or installation difficulties that may occur in traditional assembly methods. This simplifies the assembly process and improves work efficiency. The magnetic member C122 provided on the first fixing portion C12 provides additional attraction between the second carrier D2 and the first fixing portion C12, effectively preventing the risk of the second carrier D2 accidentally falling off due to factors such as vibration and impact during winding, thereby improving connection stability. Furthermore, because the first fixing portion C12 and the second carrier D2 utilize a plug-in fit of the positioning posts C121 and the positioning holes, coupled with magnetic attraction, the second carrier D2 can be easily separated from and assembled with the first fixing portion C12. The number of positioning posts C121, positioning holes, and magnetic members C122 can be set to multiple as needed and is not particularly limited herein. Specifically, in this embodiment, the positioning posts C121 are evenly spaced around the end of the first fixing portion C12. The positioning holes of the second carrier D2 adapt to the position of the positioning column C121 and are evenly spaced around the four sides of the end of the second carrier D2. The magnetic part C122 can be a magnet. The second carrier D2 can be directly made of ferromagnetic metal materials such as iron, nickel, cobalt, etc. or a mixed material, so that when the second carrier D2 is assembled to the first fixing part C12, it can be magnetically adsorbed to the end of the first fixing part C12. The second carrier D2 can also be made of insulating material, but a material that is magnetically attracted to the magnetic part C122 is provided at the end of the second carrier D2. No special restrictions are imposed here.

[0062] In some embodiments, as Figure 3 and Figure 4As shown, the power source device C11 includes a three-dimensional moving device C111, a first rotation drive device C112, a linear moving device C113 and a second rotation drive device C114; the output end of the three-dimensional moving device C111 is connected to the first rotation drive device C112 and the linear moving device C113 through a moving frame, the output end of the first rotation drive device C112 is connected to the first fixed part C12 and drives the first fixed part C12 to rotate around its own center axis, the output end of the linear moving device C113 is connected to the second rotation drive device C114 and drives the second rotation drive device C114 to move between the third position and the fourth position, and the output end of the second rotation drive device C114 is connected to the second fixed part C13 and drives the second fixed part C13 to rotate around its own center axis. Among them, the coordinated use of the three-dimensional moving device C111, such as a three-dimensional linear module, and the first rotary drive device C112, such as a rotary motor, can realize complex movements such as translation and rotation of the second carrier D2, thereby driving the second carrier D2 to realize a complex three-dimensional winding path, thereby being able to obtain a coil structure with an annular ring and two lead-out end wires. Specifically, the three-dimensional moving device C111 drives the first fixed portion C12 to move forward, backward, left, and right to wind the wire end around the first end column D26 of the second carrier D2. After the wire end is wound, the linear moving device C113 drives the second fixed portion C13 to move from the fourth position to the third position. At this time, the second fixed portion C13 abuts against the second bearing portion D22 of the second carrier D2. Subsequently, the first rotary drive device C112 and the second rotary drive device C114 respectively drive the first fixed portion C12 to rotate and the second fixed portion C14 to rotate. 3 rotates synchronously to drive the second carrier D2 to rotate and perform winding processing on the second carrier part D22 to obtain a coil. When the winding is completed, the linear motion device C113 drives the second fixing part C13 to move from the third position to the fourth position. At this time, the second fixing part C13 is separated from the second carrier D2. The three-dimensional motion device C111 then drives the first fixing part C12 to move forward, backward, left and right to wind the tail end of the wire around the second end post D27 of the second carrier D2. The wire is then cut to obtain a coil structure with an annular ring and two lead-out wires.It should be noted that since the first fixed part C12 and the second fixed part C13 need to be always arranged relative to each other, the three-dimensional moving device C111 is connected to the first rotation drive device C112 and the linear moving device C113, so that the first fixed part C12 and the second fixed part C13 can be driven to move synchronously during the process of winding the end line, so that the first fixed part C12 and the second fixed part C13 can always be in a relatively set position, and the moving direction of the second rotation drive device C114 driven by the linear moving device C113 is the extension direction from the first fixed part C12 to the second fixed part C13. Through the linear moving device C113, such as a linear module, the second fixed part C13 can be driven individually to approach or move away from the first fixed part C12, so as to form a state of abutment or separation with the second carrier D2 on the first fixed part C12.

[0063] In some embodiments, as Figure 1 、 Figure 3 and Figure 4As shown, the automatic winding machine C10 further includes a tensioning device C14 and a clamping device C15; the tensioning device C14 is disposed on a first side of the winding device C1, and the clamping device C15 is disposed on a second side of the winding device C1. Specifically, the tensioning device C14 is disposed on a first side of the winding position 102, and the clamping device C15 is disposed on a second side of the winding position 102. The tensioning device C14 is a conventional device capable of providing the necessary tension to the wire being wound to achieve wire tensioning. Specifically, the wire tensioning device C14 can be achieved through a series of mechanical structures or elastic elements (such as springs, pneumatic cylinders, or rollers driven by electric motors). When the wire passes through the tensioning device C14 from the wire supply source, the tensioning device C14 will apply a constant pulling force to the wire to ensure that the wire remains taut throughout the winding process. In combination with the wire clamping device C15 provided on the second side of the winding position 102, it accurately and firmly clamps the wire end before or at the start of wire winding. Before the start of winding, the wire clamping device C15 first fixes the wire end in a predetermined position to provide a stable foundation for subsequent winding, ensuring that the starting point of winding is accurate. After the winding is completed, the wire clamping device C15 acts again to clamp the wire tail and perform the cutting operation to ensure the integrity and safety of the wire harness. Specifically, the wire clamping device C15 includes a wire clamping rotating motor C151 and a clamping mechanism C152, wherein the clamping mechanism C152 can be a pneumatic clamp or an electromagnetic clamp, etc., which can automatically open or clamp. The output end of the wire clamping rotating motor C151 is connected to the clamping mechanism C152 and drives the clamping mechanism C152 to rotate, so as to control the clamping mechanism C152 to rotate to the active area of the fixed part, so as to facilitate the first fixed part C12 to perform the winding process of the wire end, and when the fixed part starts the coil winding process on the second carrier D2, the clamping mechanism C152 releases the wire, and the wire clamping rotating motor C151 controls the clamping mechanism C152 to rotate to the bottom to avoid the active area of the fixed part, so as to facilitate the winding process of the fixed part. After the winding process of the wire tail, the wire clamping rotating motor C151 controls the clamping mechanism C152 to rotate to the active area of the fixed part to clamp the wire tail, so as to facilitate the winding operation of the next carrier, and at this time the wire with the coil can be cut to ensure the integrity and safety of the wiring harness. It should be noted that the clamping mechanism C152 can be a mechanism that integrates clamping and shearing, or an additional scissors can be set on one side of the clamping mechanism C152 to cut the wire end, or the clamping mechanism C152 and the transfer mechanism can directly interact to form a pulling force on the wire so that the wire end is directly disconnected. There is no special restriction here.

[0064] In some embodiments, as Figure 3 and Figure 4As shown, the loading position is provided on one side of the first fixing portion C12, and the second carrier D2 is laterally assembled to the loading position. It can be understood that when the second carrier D2 is placed on the first carrier D1 of the machine base 100, the bottom end of the second carrier D2 is arranged on the first carrier D1, and the second bearing portion D22 is located at the top of the second carrier D2. When the transfer device C2 transfers the second carrier D2 to the loading position of the winding device C1 for assembly, the second carrier D2 is transformed from a vertical setting state to a lateral setting state, that is, the bottom end of the second carrier D2 is docked with the lateral loading position of the first fixing portion C12, and the second bearing portion D22 of the second carrier D2 is laterally arranged on the first fixing portion C12, thereby optimizing the winding path and facilitating subsequent winding processing.

[0065] In some embodiments, as Figure 3 and Figure 4 As shown, the transfer device C2 includes a transfer drive device C21 and two manipulators C22 connected to the transfer drive device C21. The transfer drive device C21 drives the manipulators C22 to move between the placement position 101 and the winding position 102. Specifically, the two manipulators C22 cooperate with each other. When one manipulator C22 transfers the second carrier D2 from the placement position 101 to the winding position 102, the other manipulator C22 can simultaneously transfer the wound second carrier D2 from the winding position 102 to the placement position 101 for unloading or preparation for unloading. This effectively reduces the waiting time of the workpiece, significantly shortens the production cycle, and improves the overall production capacity. Specifically in this embodiment, the transfer drive device C21 includes a first transfer drive member, two second transfer drives and two rotating drives; the first transfer drive member is arranged along the extension direction from the placement position 101 to the winding position 102, and further, the first transfer drive member is arranged along the extension direction from the placement position 101, the winding position 102 to the heating position 103, and the two second transfer drives are arranged on the first transfer drive member, and the first transfer drive member drives the two second transfer drives to move synchronously along the extension direction of the placement position 101, the winding position 102 and the heating position 103, the two second transfer drives are respectively connected to the two rotating drives, and the two rotating drives are respectively connected to the two manipulators C22, wherein the second transfer drive member drives the corresponding manipulator C22 to move up and down to approach or move away from the placement position 101 or the winding position 102 in the height direction, and the rotating drive member drives the manipulator C22 to rotate 90 degrees in the vertical direction to switch the second carrier D2 between the flat state and the side state, so that the two manipulators C22 can cooperate in the operation of transferring the second carrier D2, thereby improving work efficiency. Of course, in other embodiments, the two robots C22 can also be individually controlled by an independent transfer drive device C21, which can further improve the flexibility of transfer, and the transfer drive device C21 can be a three-dimensional linear module, etc., and there is no special limitation here.

[0066] An embodiment of the present invention further provides a winding method, which includes the following steps:

[0067] Assemble the second carrier D2 of the carrier D10 on the winding device C1;

[0068] The winding device C1 performs winding processing on the first end post D26 of the second carrier D2, and fixes the end of the coil on the first end post D26;

[0069] After the wire end is wound, the winding device C1 winds the second supporting portion D22 of the second carrier D2 to form a coil.

[0070] After the coil winding is completed, the winding device C1 performs a winding process on the second end post D27 of the second carrier D2 to fix the tail end of the coil on the second end post D27.

[0071] For ease of understanding, the following provides a specific embodiment of the winding process of the automatic winding machine C10:

[0072] The transfer device C2 transfers a second carrier D2 from the first carrier D1 on the work station disk to the heating position 103, and the first hot air blower preheats the second bearing part D22 of the second carrier D2. After the preheating is completed, the second carrier D2 is transferred to the winding position 102 and assembled on the first fixed part C12. Then the three-dimensional moving device C111 drives the first fixed part C12 to move forward, backward, left and right to wind the wire end tightened by the tensioning device C14 and the clamping device C15 around the first end column D26 of the second carrier D2. After the wire end is wound, the clamping mechanism C152 releases the wire, and the clamping rotary motor C151 controls the clamping mechanism C152 to rotate to the bottom to avoid the active area of the fixed part. The linear moving device C113 drives the second fixed part C13 to abut against the second bearing part D22 of the second carrier D2, thereby respectively abutting against the second carrier D2 through the first fixed part C12 and the second fixed part C13. The two opposite ends of the base D2 are used to dynamically lock the second carrier D2, and then the first fixed part C12 and the second fixed part C13 are driven to rotate synchronously by the first rotation drive device C112 and the second rotation drive device C114 respectively, so as to drive the second carrier D2 to rotate and perform winding processing on the second bearing part D22 to obtain a coil. When the winding is completed, the linear movement device C113 drives the second fixed part C13 to separate from the second carrier D2, and then the three-dimensional movement device C111 drives the first fixed part C12 to move forward, backward, left and right to wind the tail end of the wire around the second end column D27 of the second carrier D2. The wire clamping rotation motor C151 then controls the clamping mechanism C152 to rotate to the active area of the fixed part to clamp the wire tail, and then cuts the wire to obtain a coil structure with an annular ring and two lead-out end wires. The robot C22 transfers the second carrier D2 after winding to the first carrier D1 of the placement position 101 for the next step of welding and other processes.

[0073] In some embodiments, as Figure 9As shown, a receiving groove D24 is provided on the second carrier D2, and the second bearing portion D22 is elastically arranged in the receiving groove D24. The side walls of the second bearing portion D22 slide in conjunction with the groove walls of the receiving groove D24. The second bearing portion D22 at least partially protrudes from the surface of the second carrier D2 in a normal state. Preferably, the gap between the second bearing portion D22 and the receiving groove D24 needs to be sufficiently small and tightly fitted, that is, the side walls of the second bearing portion D22 are tightly and slidingly fitted with the groove walls of the receiving groove D24 to prevent the coil on the second bearing portion D22 from being stuck in the gap between the two when detached. Specifically, the top of the second carrier D2 is recessed downward to form the receiving groove D24, wherein the second bearing portion D22 has a cylindrical structure, and the receiving groove D24 is adapted to have a circular groove structure. Understandably, since the coil is tightly wound and adhered to the peripheral wall of the second carrier portion D22 during winding on the second carrier D2 to prevent loosening during the winding process, this enhanced adhesion makes it difficult for the coil to be smoothly removed from the second carrier portion D22. Therefore, in this embodiment, the second carrier portion D22 is elastically mounted on the second carrier D2. The portion of the second carrier portion D22 that protrudes from the surface of the second carrier D2 in its normal state is used for winding the coil. When the coil needs to be removed for the next step, an external force can be applied to the second carrier portion D22 to cause it to move downward and retract into the receiving groove D24. At this point, the coil can be removed from the second carrier portion D22 and transferred to the next workstation for processing. After the external force is removed, the second carrier portion D22 can return to its normal state under the elastic action.

[0074] Specifically in this embodiment, an elastic member D25 is disposed within the receiving groove D24, and the second supporting portion D22 is connected to the second carrier D2 via the elastic member D25. Specifically, the elastic member D25 may be a spring or other elastic component. The second supporting portion D22 elastically abuts against the bottom of the receiving groove D24 via the elastic member D25, enabling the second supporting portion D22 to move up and down along the receiving groove D25 under the elastic action of the elastic member D25, thereby facilitating the removal of the coil from the second supporting portion D22.

[0075] In some embodiments, the first supporting portion D11 is a vertical rod. The structure of the vertical rod can be a square rod, a cylindrical rod, or the like, without particular limitation. Specifically, in this embodiment, the vertical rod is a square rod so that the top of the vertical rod can fit over the PCB. Furthermore, the top of the vertical rod can be provided with a groove to retain the PCB at the top of the vertical rod.

[0076] In some embodiments, the portion of the second bearing portion D22 exposed from the second carrier D2 when in a normal state is a winding portion for winding a coil, and the winding portion is a cylindrical body. Specifically, the second bearing portion D22 is formed into a stepped column with a smaller upper portion and a larger lower portion. The upper portion of the second bearing portion D22 serves as the winding portion, and the lower portion of the second bearing portion D22 is located within the receiving groove D24. The diameter of the notch end of the receiving groove D24 is smaller than the diameter of the receiving groove, and the diameter of the notch end of the receiving groove D24 is adapted to the diameter of the upper portion of the second bearing portion D22. The stepped surface of the second bearing portion D22 restricts the lower portion of the second bearing portion D22 from escaping from the receiving groove D24.

[0077] The above embodiments are not exhaustive and may include many other embodiments not listed above. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
