[0051] A second aspect of the present invention provides an automatic RFID chip assembly method, the automatic RFID chip assembly method comprising the following steps:

[0052] The PCB board is loaded onto the first support part of the carrier, and then the workstation rotates to move the carrier to the area where the winding machine is located;

[0053] The transfer device transfers the second carrier on the workstation to the winding position of the winding machine, and the winding machine winds the second bearing part of the second carrier to obtain the coil structure.

[0054] The transfer device transfers the second carrier, after the winding is completed, to the workstation and assembles it onto the first carrier;

[0055] The rotating workstation panel moves the winding and assembled carrier to the area where the welding device is located, and the welding device welds the coil to the PCB board.

[0056] The workstation continues to rotate, moving the welded carrier to the area where the wire cutting device is located. The wire cutting device cuts off the waste wire of the welded coil.

[0057] The technical solution provided by this invention has the following advantages and effects:

[0058] (1) The RFID chip automatic assembly equipment has a rotating workstation on the base. Multiple carriers are set on the workstation along the circumferential direction of the workstation. When the workstation drives the carriers to rotate, it can drive the carriers to the winding machine, welding device and wire cutting device in sequence to perform the automated operation of coil winding, PCB board and coil welding and coil waste wire removal in sequence. There is no need for manual winding, welding and coil waste wire treatment, which effectively improves production efficiency and product quality. In addition, the carriers are of a split structure. The first carrier and the second carrier can be in a separate state or an assembled state. The first carrier carries the PCB board and the second carrier can be transferred to the winding machine for winding. The movement of the second carrier will not affect the state of the PCB board. When the second carrier is wound and then assembled back onto the first carrier, it is convenient for the subsequent PCB board and coil welding operation.

[0059] (2) By setting two heating devices, the first heating device can preheat the second bearing part of the second carrier, and then transfer the preheated second carrier to the winding machine for winding operation. At the same time, the second heating device continues to perform secondary heating during the winding synchronization stage to ensure the best melt flow of the adhesive material, while avoiding local overheating and improving the winding effect of the coil. When one second carrier is preheated by the first heating device, the winding machine can simultaneously perform secondary heating of the other second carrier. The dual-station alternating heating operation can effectively improve processing efficiency and heat utilization.

[0060] (3) The second carrier has a structure with through holes and two end posts. The structure with two end posts can produce a coil structure with an annular ring and two lead-out ends after the winding machine winds the coil. When the through hole structure is assembled back onto the first carrier after the second carrier is wound, the PCB board on the first carrier can be exposed on the second carrier and located exactly below the beginning and end of the coil. This facilitates the subsequent soldering operation of the PCB board and the beginning and end of the coil. It also facilitates the processing steps of cutting off excess copper wire and removing waste wire after soldering, thus meeting the requirement of continuous assembly of various components in the RFID chip.

[0061] (4) The first carrier is also provided with a third carrier for supporting the housing. The third carrier includes a first clamping member, a second clamping member and a first moving member. The first clamping member and the second clamping member enclose a clamping space for clamping the housing. The first clamping member is disposed on the first carrier, the second clamping member is disposed on the first moving member, and the first moving member is elastically disposed on the first carrier. The base is provided with a guide member, and the guide member is provided with an arc-shaped guide groove. The cam moves along the arc-shaped guide groove. When the workstation rotates and drives the carrier to move, the cam can enter the arc-shaped guide groove of the guide member during the rotation process and drive the cam to move along the arc-shaped guide groove during the rotation process. There is no need to set up an additional power mechanism to drive the movement of the first moving member.

[0062] (5) A receiving groove is provided on the second carrier, and the second bearing part is elastically disposed in the receiving groove. The part of the second bearing part that protrudes from the surface of the second carrier in normal state is used to wind the coil. When it is necessary to remove the coil for the next step, the second bearing part can be subjected to force by the coil assembly device to move the second bearing part toward the receiving groove to form displacement. This causes the coil wound on the second bearing part to be squeezed against the end face of the receiving groove, so that the coil is separated from the second bearing part and transferred to the housing for assembly without damaging the coil. This ensures the performance of the coil and the quality of the final product. After the external force is removed, the second bearing part can return to normal under the elastic action.

[0063] (6) The welding device sets an adjacent first and second support part on the carrier so that when the coil and PCB board are respectively supported by the two support parts, the two end wires of the coil can be just mounted on the two welding points of the PCB board. The welding component outputs a stable DC welding current to the electrode through the power supply. The resistance heat generated at the electrode pressing point welds the welding point and the end wire of the PCB board together to complete the welding operation. Compared with the existing tin soldering method, the use of solder can be omitted, thereby effectively preventing the problem of solder melting and splashing everywhere during welding, improving the product appearance and welding quality.

[0064] (7) The vibratory feeder filters shells that do not meet the expected orientation through the gaps in the screening track, and a conveyor track is set up. The conveyor track twists outward to pre-filter stacked shells, so that the shells are arranged one by one. A screening table is set at the connection between the screening track and the conveyor track. The screening table is tilted outward, and a side wing with a sharp angle is set at the exit of the conveyor track to deflect the arched parts of the shells as far back as possible, changing them to face forward. This achieves the forward-oriented orientation of the shells for feeding, which facilitates subsequent processing steps.

[0065] (8) By controlling the palletizing support assembly to switch between the first and second positions, the pallet lifting assembly drives the pallet and pallet to rise or fall. Thus, the two work together to remove the pallet from the first pallet at the upper pallet position and stack the pallet into the second pallet at the lower pallet position. There is no need to move the pallets to the upper pallet position one by one, nor is there a need to remove the pallets one by one at the lower pallet position for palletizing, which improves production line efficiency and reduces production costs.

Detailed Implementation

[0117] To facilitate understanding of the present invention, specific embodiments of the invention will be described in more detail below with reference to the accompanying drawings. Unless otherwise specified or defined, the terms "first," "second," etc., used herein are merely for distinguishing names and do not represent a specific number or order. Unless otherwise specified or defined, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. It should be noted that "fixed to" or "connected to" in this document can refer to being directly fixed to or connected to an element, or indirectly fixed to or connected to an element.

[0118] It should be noted that the structure of an RFID chip (RFID tag chip) includes a housing, a coil, and a PCB board. Therefore, this RFID chip automatic assembly equipment is suitable for automatically assembling the housing, coil, and PCB board to obtain a shaped RFID chip. Specifically, it includes automated operation steps such as PCB board punching and feeding, automatic housing shaping and feeding, coil winding, PCB board and coil welding, coil waste wire removal, coil assembly, waste wire clamping, finished product inspection, and unloading. It features low operation difficulty, high efficiency, and fully automated operation.

[0119] like Figures 1 to 41 As shown, the RFID chip automatic assembly equipment 1000 includes, but is not limited to, a base A100, a workstation A200, a PCB board loading device H10, a vibratory feeder B10, a winding machine C10, a welding device E10, a wire cutting device J10, a coil assembly device F10, a waste wire clamping device K10, a coil shaping device L10, a detection device M10, a palletizing device, and carriers D10. The workstation A200 is rotatably mounted on the base A100. Multiple carriers D10 are arranged on the workstation A200 along its circumferential direction. Adjacent to the workstation A200, the base A100 and the workstation A200 are sequentially arranged along the circumferential direction of the workstation A200, including a PCB board loading position, a housing loading position, a winding position, a welding position, a wire cutting position, a coil assembly position, a waste wire clamping position, a coil shaping position, a detection position, and a unloading position. The PCB board loading device H10, vibratory feeder B10, winding machine C10, welding device E10, wire cutting device J10, coil assembly device F10, waste wire clamping device K10, coil shaping device L10, detection device M10, and palletizing device are sequentially arranged at appropriate positions on the machine base A100, thus forming a ring around the workstation plate A200 on the machine base A100. This allows the workstation plate A200 to rotate the carrier D10, thereby rotating the carrier D10 sequentially to... The PCB board loading device H10, vibratory feeder B10, winding machine C10, welding device E10, wire cutting device J10, coil assembly device F10, waste wire clamping device K10, coil shaping device L10, inspection device M10, and stacking device perform automated operations sequentially, including PCB board punching and loading, automatic housing shaping and loading, coil winding, PCB board and coil welding, waste wire cutting, coil assembly, waste wire clamping, coil shaping, finished product inspection, and unloading. The workstation plate A200 is driven to rotate by a servo motor.

[0120] This invention provides an automatic RFID chip assembly device 1000, which includes:

[0121] Machine base A100, with workstation plate A200 rotatably mounted on machine base A100;

[0122] Multiple carriers D10 are arranged on the workstation A200 along the circumferential direction of the workstation A200.

[0123] The carrier D10 includes a first carrier D1 and a second carrier D2. The first carrier D1 is mounted on the workstation A200, and the second carrier D2 is detachably mounted on the first carrier D1. The first carrier D1 has a first support portion D11 for placing the PCB board; the second carrier D2 has a second support portion D22 for winding the coil. The carrier D10 is a split-type carrier, meaning that the first carrier D1 and the second carrier D1 can be in a separate or assembled state. The PCB board is loaded onto the first support portion D11 of the first carrier D1, and the first carrier D1 is fixed to the workstation A200. The second carrier D2 can be detached from the first carrier D1 for winding.

[0124] A winding machine C10 is mounted on a base A100. The winding machine C10 is used to wind a coil on the second bearing part D22 of the second carrier D2.

[0125] The welding device E10 is mounted on the base A100 and is used to weld the PCB board and the coil together.

[0126] The wire cutting device J10 is installed on the base A100. The wire cutting device J10 is used to cut off the waste wire of the coil after welding.

[0127] Transfer device C2, which is in conjunction with at least carrier D10 and winding machine C10.

[0128] Among them, the winding machine C10, the welding device E10 and the cutting device J10 are arranged sequentially along the circumferential direction of the workstation plate A200.

[0129] Based on the aforementioned RFID chip automatic assembly equipment 1000, the RFID chip automatic assembly method includes the following steps:

[0130] The PCB board is loaded onto the first bearing part D11 of the carrier D10, and then the station plate A200 rotates to move the carrier D10 to the area where the winding machine C10 is located.

[0131] The transfer device C2 transfers the second carrier D2 on the workstation plate A200 to the winding position of the winding machine C10. The winding machine C10 winds the second bearing part D22 of the second carrier D2 to obtain the coil structure.

[0132] The transfer device C2 transfers the second carrier D2, after the winding is completed, to the workstation A200 and assembles it onto the first carrier D1;

[0133] The workstation plate A200 rotates, driving the winding and assembled carrier D10 to the area where the welding device E10 is located. The welding device E10 welds the coil to the PCB board.

[0134] The workstation plate A200 continues to rotate, driving the welded carrier D10 to the area where the wire cutting device J10 is located. The wire cutting device J10 cuts off the waste wire of the welded coil.

[0135] In summary, the RFID chip automatic assembly equipment 1000 has a rotating workstation plate A200 mounted on a base A100. Multiple carriers D10 are positioned on the workstation plate A200 along its circumferential direction. A winding machine C10, a welding device E10, and a cutting device J10 are sequentially positioned at appropriate locations on the base A100. This ensures that when the workstation plate A200 rotates the carriers D10, it sequentially rotates the carriers D10 to the positions of the winding machine C10, welding device E10, and cutting device J10. The system automates the winding, PCB board and coil soldering, and coil waste wire removal processes sequentially, eliminating the need for manual winding, soldering and waste wire disposal. This effectively improves production efficiency and product quality. The carrier D10 is a split carrier, and the first carrier D1 and the second carrier D2 can be in a separate or assembled state. This allows the second carrier D2 to be transferred to the winding machine C10 for winding. After winding, it is reassembled onto the first carrier D1, facilitating subsequent PCB board and coil soldering operations.

[0136] In some embodiments, such as Figures 3 to 7As shown, the second carrier D2 has a through hole D21, and two end posts D23 protruding from the second carrier D2 are provided on one side edge of the second carrier D2 near the through hole D21. When the second carrier D2 is assembled with the first carrier D1, the first bearing part D11 of the first carrier D1 passes through the through hole D21, and the through hole D21 is located between the end posts D23 and the second bearing part D22. Understandably, the carrier D10 is a split-type carrier, meaning that the first carrier D1 and the second carrier D2 can be in a separate or assembled state. The PCB board is loaded onto the first support portion D11 of the first carrier D1, and the first carrier D1 is fixed on the workstation tray A200. The second carrier D2 can be detached from the first carrier D1 for winding processing. Since the first support portion D11 of the first carrier D1 is a through hole D21 in the second carrier D2, the detachment of the second carrier D2 from the first carrier D1 will not affect the placement of the PCB board on the first support portion D11, and will allow the first carrier D2 to be assembled in the first carrier D1. The second carrier D2 can be positioned on the first carrier D1, and the PCB board on the first support part D11 can be exposed on the second carrier D2. The PCB board and the coil are arranged side by side on the surface of the second carrier D2. Therefore, the coil can be directly wound on the carrier D10 to obtain the coil. The PCB board and the coil are soldered, and the waste wire is cut off and removed. Therefore, the carrier D10 can at least adapt to the PCB board loading, coil winding, soldering, wire cutting and waste wire removal processes in the automatic assembly of RFID chips, and meet the continuous work of assembling various components in RFID chips.

[0137] Based on the aforementioned RFID chip automatic assembly equipment 1000, the RFID chip automatic assembly method includes the following steps:

[0138] The PCB board is loaded onto the first bearing part D11 of the carrier D10, and then the station plate A200 rotates to move the carrier D10 to the area where the winding machine C10 is located.

[0139] The transfer device C2 transfers the second carrier D2 on the workstation plate A200 to the winding position of the winding machine C10. The winding machine C10 sequentially winds one end post D23, the second bearing part D22 and the other end post D23 of the second carrier D2 to obtain a coil structure with two end wires.

[0140] The transfer device C2 transfers the second carrier D2 after the winding is completed to the work station plate A200 and assembles it on the first carrier D1. The first bearing part D11 passes through the through hole D21 of the second carrier D2. At this time, the two solder points of the PCB board are located below the two end lines of the coil.

[0141] The workstation plate A200 rotates, driving the winding and assembled carrier D10 to the area where the welding device E10 is located. The welding device E10 then welds the two ends of the coil to the two welding points on the PCB board in sequence.

[0142] The workstation plate A200 continues to rotate, driving the welded carrier D10 to the area where the wire cutting device J10 is located. The wire cutting device J10 cuts off the waste wire of the welded coil.

[0143] In summary, this RFID chip automatic assembly equipment 1000, by setting a rotating workstation plate A200 on a base A100, and multiple carriers D10 arranged circumferentially on the workstation plate A200, and the winding machine C10, welding device E10, and wire cutting device J10 sequentially arranged in appropriate positions on the base A100, allows the workstation plate A200 to rotate the carriers D10, thereby sequentially rotating the carriers D10 to the positions of the winding machine C10, welding device E10, and wire cutting device J10, to perform automated operations of coil winding, PCB board and coil welding, and coil waste wire removal in sequence, eliminating the need for manual winding, welding, and... The waste wire treatment of the coil effectively improves production efficiency and product quality. Combined with the fact that the carrier D10 is a split carrier D10, the first carrier D1 and the second carrier D2 can be in a separate or assembled state, and the structure of the through hole D21 and the two end posts D23 of the second carrier D2, when the second carrier D2 is wound and assembled back onto the first carrier D1, the PCB board on the first bearing part D11 can be exposed on the second carrier D2 and located exactly below the beginning and end of the coil wire. This facilitates the subsequent soldering operation of the PCB board and the beginning and end of the coil wire. In addition, the structure of the two end posts D23 can facilitate the removal of excess copper wire after soldering.

[0144] In some embodiments, such as Figures 8 to 13As shown, the RFID chip assembly equipment 100 also includes a first heating device C3 and a second heating device C4. The first heating device C3 is located on the base A100 adjacent to the winding machine C10, and the second heating device C4 is located on the winding machine C10. When the transfer device C2 transfers the second carrier D2 to the first heating device C3, the first heating device C3 heats the second carrier D22. When the second carrier D2 is loaded onto the winding machine C10, the second heating device C4 heats the second carrier D22 a second time, and the winding machine C10 simultaneously winds the second carrier D22. Currently, the winding machine C10 typically uses a single hot air structure to complete heating in one go during the winding process. However, it has been found that this one-time heating operation leads to excessive instantaneous temperature differences in the coil's adhesive material. The adhesive material generates internal stress due to rapid curing, reducing the bonding strength, and heating to the preset temperature in one go requires a considerable amount of time. Therefore, in this embodiment, two heating devices are provided. The first heating device C3 is located at the machine base A100, and the second heating device C4 is located on the winding machine C10. The first heating device C3 can gradually heat the second carrier part D22 of the second carrier D2 from room temperature in a stepped heating mode, so that the second carrier part D22 is preheated. Then, the preheated second carrier D2 is transferred to the winding machine C10 for winding operation. At the same time, the second heating device C4 continuously performs secondary heating during the winding synchronization stage to ensure the best melt flow of the adhesive material, while avoiding local overheating and improving the winding effect of the coil. When one second carrier D2 is preheated by the first heating device C3, the winding machine C10 can simultaneously perform secondary heating of the other second carrier D2. The dual-station alternating heating operation can effectively improve processing efficiency and heat utilization.

[0145] In some embodiments, two first heating devices C3 may be provided, and two heating positions may be adapted to be provided on the machine base A100, so that the second carrier D2 can form three heatings through the three heating devices, which can have a better heating effect, further reduce the heating time, and improve the processing efficiency.

[0146] In some embodiments, the first heating device C3 and the second heating device C4 are both hot air blowers. The hot air blows hot air toward the second support part D22 of the second carrier D2. The hot air flows in the space to achieve non-contact heating, which can make the temperature of the second support part D22 of the second carrier D2 more uniform.

[0147] For ease of understanding, the specific structure and functions of each component of the RFID chip automatic assembly equipment 1000 of the present invention will be described in detail below with reference to the accompanying drawings.

[0148] Winding machine C10:

[0149] The winding machine C10 includes a winding device C1, such as... Figures 8 to 13 As 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. The first fixing part C12 is provided with a loading position. The end of the second carrier D2 away from the second bearing part D22 is detachably assembled to the loading position. The second fixing part C13 has a first position and a second position. When the second fixing part C13 is in the first 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. When the second fixing part C13 is in the second position, the second fixing part C13 disengages 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 fixing part C12, and assembles the end of the second carrier D2 away from the second bearing part D22 onto the loading position on the first fixing part C12. The power source device C11 drives the first fixing part C12 to move forward, backward, left, and right, winding the wire end onto one of the end posts D23 of the second carrier D2. After the wire end is wound, the power source device C11 drives the second fixing part C13 to move from the second position to the first position. At this time, the second fixing part C13 abuts against the second bearing part D22 of the second carrier D2. Thus, the first fixing part C12 and the second fixing part C13 abut against the opposite ends of the second carrier D2, dynamically locking the second carrier D2 and ensuring... The second bearing part D22 is positioned between the second carrier D2 and the second fixing part C13, facilitating the winding of the second bearing part D22. Subsequently, the power source device C11 drives the first fixing part C12 to rotate and the second fixing part C13 to move synchronously, thereby driving the second carrier D2 to rotate and wind the second bearing part D22 of the second carrier D2 to obtain a coil. After the winding is completed, the second fixing part C13 moves from the first position to the second position. At this time, the second fixing part C13 is detached from the second carrier D2. Then, the power source device C11 drives the first fixing part C12 to move forward, backward, left, and right to wind the end of the wire onto the other end post D23 of the second carrier D2. The wire is then cut to obtain a coil structure with a ring and two lead wires.

[0150] In some embodiments, the loading position is a plurality of positioning posts C121 disposed at the end of the first fixing part C12, and the second carrier D2 is provided with a plurality of fixing holes adapted to the positioning posts C121. The second carrier D2 is assembled to the first fixing part C12 by inserting and engaging with the positioning posts C121 through the fixing holes, and the end of the first fixing part C12 is also provided with a magnetic element C122 that is magnetically attracted to the second carrier D2. The insertion and engagement of the positioning post C121 with the fixing hole allows the second carrier D2 to be quickly and accurately positioned on the first fixing part C12, avoiding misalignment or installation difficulties that may occur in traditional assembly methods. This simplifies the assembly process and improves work efficiency. Combined with the structure of the magnetic component C122 on the first fixing part C12, it provides additional attraction between the second carrier D2 and the first fixing part C12, effectively preventing the second carrier D2 from accidentally falling off during winding due to vibration, impact, or other factors, thus improving connection stability. Furthermore, because the first fixing part C12 and the second carrier D2 employ the insertion and engagement of the positioning post C121 and fixing hole, along with magnetic adsorption, the second carrier D2 can be easily separated and assembled from the first fixing part C12. The number of positioning posts C121, fixing holes, and magnetic components C122 can be configured as needed, without any particular limitation. Specifically, in this embodiment, the positioning posts C121 are evenly spaced around the perimeter of the end of the first fixing part C12. The fixing holes of the second carrier D2 are adapted to the position of the positioning post C121 and are evenly spaced around the end of the second carrier D2. The magnetic component C122 can be a magnet. The second carrier D2 can be made directly from ferromagnetic metal materials such as iron, nickel, cobalt, or mixed materials, so that when the second carrier D2 is assembled to the first fixing part C12, it can be magnetically attracted to the end of the first fixing part C12. Alternatively, the second carrier D2 can be made of insulating material, but the end of the second carrier D2 is provided with a material that is magnetically attracted to the magnetic component C122. No special restrictions are made here.

[0151] In some embodiments, the power source device C11 includes a three-dimensional moving device C111, a first rotary driving device C112, a linear moving device C113, and a second rotary driving device C114. The output end of the three-dimensional moving device C111 is connected to the first rotary driving device C112 and the linear moving device C113 via a moving frame. The output end of the first rotary driving device C112 is connected to the first fixed part C12 and drives the first fixed part C12 to rotate around its own central axis. The output end of the linear moving device C113 is connected to the second rotary driving device C114 and drives the second rotary driving device C114 to move between a first position and a second position. The output end of the second rotary driving device C114 is connected to the second fixed part C13 and drives the second fixed part C13 to rotate around its own central axis. The three-dimensional moving device C111, such as a three-dimensional linear module, and the first rotary driving device C112, such as a rotary motor, work together to realize complex movements such as translation and rotation of the second carrier D2, thereby driving the second carrier D2 to achieve a complex three-dimensional winding path, thus obtaining a coil structure with a ring and two lead-out ends. Specifically, the three-dimensional moving device C111 drives the first fixed part C12 to move forward, backward, left, and right to wind the wire end onto one of the end posts D23 of the second carrier D2. After the wire end is wound, the linear moving device C113 drives the second fixed part C13 to move from the second position to the first position. At this time, the second fixed part C13 abuts against the second bearing part D22 of the second carrier D2. Subsequently, the first rotary driving device C112 and the second rotary driving device C114 respectively drive the first fixed part C12 to rotate and the second fixed part C112 to rotate. 3. The synchronous rotation drives the second carrier D2 to rotate and wind the second carrier part D22 to obtain a coil. After the winding is completed, the linear moving device C113 drives the second fixed part C13 to move from the first position to the second position. At this time, the second fixed part C13 is separated from the second carrier D2. Then, the three-dimensional moving device C111 drives the first fixed part C12 to move forward, backward, left and right to wind the end of the wire onto the other end post D23 of the second carrier D2. Then the wire is cut to obtain a coil structure with a ring and two lead wires.It should be noted that, since the first fixed part C12 and the second fixed part C13 need to be always positioned relative to each other, the three-dimensional moving device C111 is connected to the first rotary driving device C112 and the linear moving device C113. During the winding of the end line, the first fixed part C12 and the second fixed part C13 can be moved synchronously, so that the first fixed part C12 and the second fixed part C13 are always in a relative position. The direction of movement of the linear moving device C113 driving the second rotary driving device C114 is the extension direction from the first fixed part C12 to the second fixed part C13. Through this linear moving device C113, such as a linear module, the second fixed part C13 can be moved closer to or away from the first fixed part C12, so as to form a contact or separation state with the second carrier D2 on the first fixed part C12.

[0152] In some embodiments, the winding machine C10 further includes a tensioning device C14 and a clamping device C15; the tensioning device C14 and the clamping device C15 are disposed opposite to each other on both sides of the winding machine C1. The tensioning device C14 is a conventional device capable of providing the necessary tension to the wire being wound, specifically achieved through a series of mechanical structures or elastic elements (such as springs, pneumatic cylinders, or electric motor-driven rollers). When the wire passes through the tensioning device C14 from the wire supply source, the tensioning device C14 applies a constant tension to the wire, ensuring that the wire remains taut throughout the winding process. Combined with the wire clamping device C15 located on the other side of the winding device C1, it accurately and firmly clamps the wire end before or at the end of the winding. Before the winding begins, the wire clamping device C15 first fixes the wire end in a predetermined position, providing a stable foundation for subsequent winding and ensuring that the starting point of the winding is accurate. After the winding is completed, the wire clamping device C15 acts again to clamp the wire end and perform a cutting operation, ensuring the integrity and safety of the wire bundle. Specifically, the wire clamping device C15 includes a wire clamping rotary motor C151 and a clamping mechanism C152. The clamping mechanism C152 can be a pneumatic gripper or an electromagnetic chuck, or other device capable of automatically opening or clamping. The output end of the wire clamping rotary motor C151 is connected to the clamping mechanism C152 and drives the clamping mechanism C152 to rotate, thereby controlling the clamping mechanism C152 to rotate to the movable area of ​​the fixed part, facilitating the winding of the wire end by the first fixed part C12. When the fixed part starts the coil winding process for the second carrier D2, the clamping mechanism C152 releases the wire, and the wire clamping rotary motor C151 controls the clamping mechanism C152 to rotate downward to avoid the movable area of ​​the fixed part, facilitating the winding process of the fixed part. After the winding process of the wire end, the wire clamping rotary motor C151 controls the clamping mechanism C152 to rotate to the movable area of ​​the fixed part to clamp the wire end, so as to facilitate the winding operation of the next carrier. At this time, the wire with the wound coil can be cut to ensure the integrity and safety of the wire bundle. It should be noted that the clamping mechanism C152 can be a mechanism that integrates clamping and cutting, or an additional pair of scissors can be set on one side of the clamping mechanism C152 to cut the end of the wire, or the clamping mechanism C152 and the transfer mechanism can interact to form a pulling force on the wire so that the end of the wire is directly broken. No special restrictions are made here.

[0153] In some embodiments, a loading position is provided on one side of the first fixing part C12, and the second carrier D2 is laterally assembled to the loading position. Understandably, when the second carrier D2 is placed on the first carrier D1 on the workstation A200, the bottom end of the second carrier D2 is positioned on the first carrier D1, and the second bearing part D22 is located at the top end of the second carrier D2. After the transfer device C2 transfers the second carrier D2 to the loading position of the winding device C1 for assembly, the second carrier D2 changes from a vertically positioned state to a laterally positioned state, that is, the bottom end of the second carrier D2 is aligned with the lateral loading position of the first fixing part C12, and the second bearing part D22 of the second carrier D2 is laterally positioned on the first fixing part C12. This optimizes the winding path and facilitates subsequent winding processing.

[0154] In some embodiments, the transfer device C2 includes a transfer drive device C21 and two transfer robots C22 connected to the transfer drive device C21. Specifically, the two transfer robots C22 cooperate, and while one transfer robot C22 transfers the second carrier D2 from the first carrier D1 of the workstation A200 to the winding machine C10, the other transfer robot C22 can simultaneously transfer the wound second carrier D2 from the winding machine C10 to the first carrier D1, effectively reducing the waiting time of the workpiece, significantly shortening the production cycle, and improving the overall production capacity. Specifically, in this embodiment, the transfer robot C22 is driven to move by a transfer drive device C21. Specifically, the transfer drive device C21 includes a first transfer drive component, two second transfer drive components, and two rotation drive components. The first transfer drive component is arranged along the extension direction from the first carrier D1 to the winding machine C10. Further, the first transfer drive component is arranged along the extension direction from the first heating device C3 and the first carrier D1 to the winding machine C10. The two second transfer drive components are disposed on the first transfer drive component, and the first transfer drive component drives the two second transfer drive components along the first carrier D1. 1. The winding machine C10 and the first heating device C3 move in the extending direction. Two second transfer drive components are respectively connected to two rotation drive components, and the two rotation drive components are respectively connected to two transfer manipulators C22. The second transfer drive components drive the corresponding transfer manipulators C22 to move up and down to move closer to or further away from the second carrier D2 in the height direction. The rotation drive components drive the transfer manipulators C22 to rotate 90 degrees vertically to switch between a flat and side-lying position for the second carrier D2, enabling the two transfer manipulators C22 to cooperate in transferring the second carrier D2, thus improving work efficiency. Of course, in other embodiments, the two transfer manipulators C22 can also be individually controlled by a separate transfer drive device C21, which can further improve the flexibility of transfer. The transfer drive device C21 can be a three-dimensional linear module, etc., and no particular limitation is made here.

[0155] Vehicle D10:

[0156] like Figures 3 to 7 As shown, the first carrier D1 of the carrier D10 is also provided with a third carrier part D14 for supporting the housing. This third carrier part D14 supports the housing of the RFID chip, ensuring stable placement and precise positioning of the housing. Therefore, the carrier D10 can integrate three carrier parts to respectively hold the PCB board, coil, and housing of the RFID chip. After the coil is soldered to the PCB board to form a shaped coil, and after soldering and cutting off the waste wire, it can be directly transferred to the third carrier part D14 for precise alignment and assembly with the housing. The housing has an annular storage slot adapted to the coil and a square storage slot adapted to the PCB board, and the annular and square storage slots are connected. This results in a formed RFID chip, achieving high efficiency, integration, and flexibility in the RFID chip assembly process.

[0157] In some embodiments, the third support portion D14 includes a first clamping member D141, a second clamping member D142, and a first moving member D143. The first clamping member D141 and the second clamping member D142 enclose a clamping space for the RFID chip housing. The first clamping member D141 is disposed on the first carrier D1, and the second clamping member D142 is disposed on the first moving member D143. The first moving member D143 is elastically disposed on the first carrier D1. When the first moving member D143 is in a third position, the second clamping member D142 is close to the first clamping member D141. When the first moving member D143 is in a fourth position, the second clamping member D142 is away from the first clamping member D141. Thus, the third support portion D14, through the cooperation of the first clamping member D141, the second clamping member D142, and the movable first moving member D143, jointly achieves stable clamping and convenient release of the RFID chip housing. Specifically, the second clamping member D142 is disposed on the first moving member D143, serving as the moving end of the clamping system. Driven by the first moving member D143, it can achieve relative movement with the first clamping member D141. The first moving member D143 is elastically disposed on the first carrier D1 and can move freely within a certain range. The movement trajectory and position of the first moving member D143 can be precisely controlled by a sophisticated mechanical structure or control system to ensure the accuracy and reliability of the clamping action. For example, in this embodiment, the base A100 is provided with a guide member A210, which has an arc-shaped guide groove A211. The first moving member D143 is provided with a cam D16, which cooperates with the arc-shaped guide groove A211 to position the first moving member D143 in a third or fourth position. Specifically, the movement trajectory and position of the first moving member D143 are guided and controlled by the guide member A210 on the machine base A100. The guide member A210 forms an arc-shaped guide groove A211. The cam D16 moves along the arc-shaped guide groove A211. When the workstation plate A200 rotates, driving the carrier D10 to move, the cam D16 can follow the rotation and enter the arc-shaped guide groove A211 of the guide member A210. During the rotation, the cam D16 moves along the arc-shaped guide groove A211, so that the first moving member D143 drives the second clamping member D142 to move to the third or fourth position, so as to move closer to or away from the first clamping member D141. No additional power mechanism is required to drive the movement of the first moving member D143. In addition, the rolling cam D16 is designed to form a rolling engagement with the guide member A210, which greatly reduces the friction and resistance during the movement.Specifically, in this embodiment, the first moving member D143 is elastically connected to the first carrier D1 via a spring, wherein the direction of the elastic potential energy of the spring is consistent with the direction of movement of the first moving member D143, so that the first moving member D143 can move relative to the first carrier D1, while ensuring good restoring force and stability. When the cam D16 moves out of the guide A210 of the base A100, it can restore its original shape through its elastic force.

[0158] In some embodiments, the first moving member D143 is further provided with a positioning member D145; the first carrier D1 is provided with a positioning hole D121, and the second carrier D2 is provided with a positioning groove D29. When the first moving member D143 is in the third position, the positioning member D145 passes through the positioning hole D121 and is limited to the positioning groove D29. When the first moving member D143 is in the fourth position, the positioning member D145 disengages from the positioning groove D29. Specifically, through the positioning function of the positioning component D145, when the second carrier D2 is assembled onto the first carrier D1, the position of the first moving component D143 is adjusted to the third position. At this time, the positioning component D145 can be inserted into the positioning groove D29 of the second carrier D2 to fix the position of the second carrier D2 onto the first carrier D1. When it is necessary to detach the second carrier D2 from the first carrier D1, the position of the first moving component D143 is adjusted to the fourth position. At this time, the positioning component D145 disengages from the positioning groove D29, and the position of the second carrier D2 is in an movable state, which can be quickly detached from the first carrier D1. Since both the second clamping member D142 and the positioning member D145 are mounted on the first moving member D143, when the first moving member D143 moves to the third position, the second clamping member D142 is clamped relative to the first clamping member D141. Simultaneously, the positioning member D145 is inserted into the positioning groove D29 of the second carrier D2 to fix the position of the second carrier D2 onto the first carrier D1. When the first moving member D143 moves to the fourth position, the second clamping member D142 is open relative to the first clamping member D141, allowing the housing to be easily removed or inserted. At the same time, the positioning member D145 disengages from the positioning groove D29, and the second carrier D2 becomes movable, allowing it to be quickly detached from the first carrier D1. Therefore, multiple guide members A210 can be set at appropriate positions on the base A100. Specifically, the guide member A210 can be set at the position where the housing is loaded, the position where the automatic winding is performed, the position where the coil is assembled, and the position where the assembled RFID chip is unloaded. When the workstation plate A200 rotates to the position of the guide member A210, the first clamping member D141 and the second clamping member D142 move away from each other to release the housing and the second carrier D2. Specifically, one side of the second carrier D2 is provided with a long strip-shaped positioning groove D29, and the first moving member D143 is provided with two positioning members D145, such as positioning pins. Through the positioning cooperation of the two positioning pins and the positioning groove D29, the second carrier D2 can be stably fixed on the first carrier D1.

[0159] In some embodiments, the first carrier D1 is provided with a guide device D17 along the moving direction of the first moving member D143, and the first moving member D143 moves linearly along the guide device D17. The guide device D17 can be a sliding pair structure. Through the tight cooperation between the slider E162 and the slide rail of the sliding pair structure, the movement trajectory of the first moving member D143 is restricted, ensuring that it can only move along a predetermined linear direction. This effectively prevents the first moving member D143 from deviating, wobbling, or rotating during movement, thereby ensuring the accuracy and stability of its movement. Alternatively, the guide device D17 can also be a rolling pair structure, etc., without particular limitation.

[0160] In some embodiments, the clamping space formed by the first clamping member D141 and the second clamping member D142 is adapted to the shape of the housing, wherein the first clamping member D141 has a groove structure with an opening on one side, and the second clamping member D142 is correspondingly disposed at the opening of the first clamping member D141.

[0161] In some embodiments, the first carrier D1 is provided with a limiting groove D15, and the second carrier D2 is assembled onto the limiting groove D15 of the first carrier D1. It can be understood that the structure of the first carrier D1 with the limiting groove D15 facilitates the precise insertion of the second carrier D2, avoids deviations during assembly, ensures the stability and accuracy of the overall structure, and effectively prevents the first carrier D1 and the second carrier D2 from misaligning due to vibration, impact, or other factors during use.

[0162] Specifically, in this embodiment, the first carrier D1 is provided with at least two limiting members with an L-shaped cross-section, and the limiting members are provided with positioning holes D121. Each limiting member cooperates to form a limiting groove D15, and there is a gap between adjacent limiting members. Specifically, in this embodiment, four limiting members are provided, each corresponding to one of the four corners of the second carrier D2, so that the corners of the limiting members fit the corners of the second carrier D2, ensuring that the second carrier D2 can be accurately positioned and fixed in both the horizontal and vertical directions. The gap between adjacent limiting members saves material costs and makes the entire system more compact and lightweight. Of course, in other embodiments, the limiting member can be a one-piece molded square ring, and no particular limitation is made here.

[0163] In some embodiments, the second carrier D2 includes a top plate D26, a bottom plate D27, and a connecting post D28; the top plate D26 and the bottom plate D27 are connected by the connecting post D28, and the cross-sectional area of ​​the connecting post D28 is smaller than the cross-sectional areas of the top plate D26 and the bottom plate D27. Since the second carrier D2 needs to be gripped by a transfer robot C22 for winding operations, a gripping point needs to be formed at the top plate D26 to facilitate gripping by the transfer robot C22. Therefore, in this embodiment, by setting the cross-sectional area of ​​the connecting post D28 to be small, the connecting post D28 will not become an obstacle during the gripping process. When the transfer robot C22 grips the top plate D26, it can more easily bypass the connecting post D28 and directly act on the top plate D26, improving the ease of gripping.

[0164] In some embodiments, the thickness of the top plate D26 is less than the thickness of the bottom plate D27. Understandably, the greater thickness of the bottom plate D27 than the top plate D26 results in a larger mass and volume in the bottom structure, creating a bottom-heavy, top-light structure. This allows the center of gravity to be located in the lower half of the second support D2, enabling better distribution and bearing of loads from above or the sides, thereby effectively improving overall stability.

[0165] In some embodiments, a receiving groove D24 is formed on the second carrier D2, and the second supporting part D22 is elastically disposed in the receiving groove D24. Preferably, the sidewall of the second supporting part D22 is tightly and slidably engaged with the groove wall of the receiving groove D24, and the second supporting part D22 normally protrudes at least partially from the surface of the second carrier D2. The state of tight and slidable engagement between the second supporting part D22 and the groove wall of the receiving groove D24 is such that the second supporting part D22 can move up and down relative to the receiving groove D24, either exposed or retracted within the second carrier D2, and the gap between the second supporting part D22 and the receiving groove D24 must also be sufficiently small and tightly fitted to prevent the coil on the second supporting part D22 from getting stuck in the gap when disengaged. Specifically, the top end of the second carrier D2 is recessed downwards to form the receiving groove D24. Understandably, because the coil is tightly wound and adhered to the peripheral wall of the second support 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 detach smoothly from the second support portion D22. Therefore, in this embodiment, the second support portion D22 is elastically disposed on the second carrier D2. Specifically, a first elastic element D25 is provided in the receiving groove D24 of the second carrier D2, and the second support portion D22 is connected to the second carrier D2 through the first elastic element D25. The second support portion D22, normally protruding from the surface of the second carrier D2, is used for winding coils. When it is necessary to remove the coil for the next operation, the coil assembly device F10 can apply force to the second support portion D22 to move it toward the receiving groove D24 and create displacement. During the movement of the second support portion D22 relative to the carrier D10, the coil wound on the second support portion D22 will be squeezed against the end face of the receiving groove D24, thereby causing the coil to detach from the second support portion D22 and be transferred to the housing for assembly. After the external force is removed, the second support portion D22 can return to its normal state under elastic action.

[0166] In some embodiments, when the second support portion D22 is in its normal state, the portion exposed outside the second carrier D2 is a winding portion for winding a coil, and the winding portion is a cylinder. Specifically, the second support portion D22 forms a stepped cylinder with a smaller upper part and a larger lower part. The upper part of the second support portion D22 is the winding portion, and the lower part of the second support portion D22 is located in the receiving groove D24. The diameter of the groove opening end of the receiving groove D24 is smaller than the diameter of the receiving groove D24, and the diameter of the groove opening end of the receiving groove D24 is adapted to the diameter of the upper part of the second support portion D22. The stepped surface of the second support portion D22 restricts the lower part of the second support portion D22 from disengaging from the receiving groove D24.

[0167] Coil assembly device F10:

[0168] like Figure 6 , Figure 7 , Figures 20 to 25 As shown, the coil assembly device F10 includes a pushing device F1 and a conveying device F2 movably mounted on the base A100; the conveying device F2 cooperates with at least the second support portion D22 and the third support portion D14. The pushing device F1 has a fifth position or a sixth position. When the pushing device F1 is in the fifth position, it is separated from the second support portion D22, and the second support portion D22 is in its normal state and at least partially exposed to the second carrier D2. When the pushing device F1 is in the sixth position, it abuts against the second support portion D22, and the second support portion D22 is displaced towards the receiving groove D24. Specifically, when the pushing device F1 is in the fifth position, the pushing device F1 is separated from the second support portion D22, and the second support portion D22 is in its normal state and at least partially exposed to the second carrier D2, preferably partially exposed. The portion of the second support portion D22 that protrudes from the surface of the carrier D10 in its normal state is used for winding the coil. When the pushing device F1 switches to the sixth position, it abuts against the second support part D22, thereby driving the second support part D22 to move towards the receiving groove D24. During the movement of the second support part D22 relative to the second carrier D2, the coil wound on the second support part D22 will be pressed against the end face of the receiving groove D24, thereby causing the coil to detach from the second support part D22. The coil is then transferred to the housing for assembly. The detached coil and PCB board are transported to the third support part D14 where the housing is located by the conveying device F2. Therefore, the coil assembly device F10 can quickly and smoothly detach the coil attached to the second support part D22 and automatically transfer the coil and PCB board to the housing to complete the assembly without damaging the coil, thus ensuring the performance of the coil and the quality of the final product.

[0169] In some embodiments, the jacking device F1 includes a lifting drive device F11 and a jacking member F12. The jacking member F12 is located above the second support portion D22 and is at least partially opposite to the second support portion D22. The lifting drive device F11 is mounted on the base A100, and its output end is connected to the jacking member F12, driving the jacking member F12 to move up and down to the fifth or sixth position, so that the jacking member F12 leaves or abuts against the second support portion D22. The jacking member F12 may be partially opposite to the second support portion D22, or it may be entirely opposite to the second support portion D22, as long as it abuts against the second support portion D22 during downward movement. No particular limitation is imposed, and there is no need for precise structural correspondence between the two, thus reducing structural accuracy and cost. The lifting drive device F11 controls the pusher F12 to move downward to the sixth position. At this time, the pusher F12 abuts against the second support part D22, and the second support part D22 moves towards the receiving groove D24. At this time, the coil can be detached from the second support part D22. After the lifting drive device F11 controls the pusher F12 to leave the second support part D22, the second support part D22 returns to its normal state under its own elasticity.

[0170] In some embodiments, the handling device F2 includes a coil moving mechanism F21 and a clamping device F22. The clamping device F22 includes a connecting frame F221 and a first clamping structure F222 for clamping the PCB board and a second clamping structure F223 for clamping the coil, both disposed on the connecting frame F221. The coil moving mechanism F21 is connected to the connecting frame F221 and drives the connecting frame F221 to move between the second support portion D22 and the third support portion D14. By providing two clamping structures, the two clamping structures can independently clamp the coil and the PCB board respectively. Therefore, the clamping state of the clamping structures can be adjusted according to the specific shapes of the coil and the PCB board to securely clamp the coil and the PCB board, avoiding clamping damage. The clamped coil and the PCB board are then simultaneously transferred from the second support portion D22 to the third support portion D14 for assembly.

[0171] In some embodiments, the second clamping structure F223 has a clamping space for accommodating the coil, and the connecting frame F221 is also provided with a guide tube F3 communicating with the clamping space at the position corresponding to the clamping space. When the connecting frame F221 is located above the second bearing part D22, the pusher F12 is movably inserted through the guide tube F3. Understandably, on the one hand, the guide tube F3 can provide a precise movement path for the pusher F12, ensuring that the pusher F12 maintains a straight line during movement, effectively preventing the pusher F12 from deviating or swaying during movement. On the other hand, the guide tube F3 is located above and connected to the clamping space of the second clamping structure F223, allowing the pusher F12 to pass through the middle of the second clamping structure F223. The second clamping structure F223 and the pusher F12 will not interfere with each other. Therefore, the pusher F12 can enter the second clamping structure F223 along the guide tube F3 to push the second bearing part D22. After the pusher F12 pushes the second bearing part D22 back into the receiving groove D24, and the second clamping structure F223 clamps the coil and moves upward, the pusher F12 releases the second bearing part D22.

[0172] Specifically, in this embodiment, both the first clamping structure F222 and the second clamping structure F223 include a clamping drive device F2231, a first clamping member F2232, and a second clamping member F2233. The clamping drive device F2231 is connected to at least one of the first clamping member F2232 and the second clamping member F2233 to drive the first clamping member F2232 and the second clamping member F2233 to be in a clamping state or an open state. The clamping drive device F2231 can be a pneumatic drive device, an electric drive device, or a hydraulic drive device, etc. The clamping drive device F2231 enables the opening and closing of the two clamping members to achieve clamping or opening. The structure by which the clamping drive device F2231 drives the clamping members to clamp or open can be a conventional structure, such as using a linkage mechanism, a gear and rack meshing transmission, or the movement of the slider E162 to drive the clamping members to clamp or open, etc., which will not be specifically described here.

[0173] In some embodiments, the clamping device F22 further includes a first driving device F211, a second driving device F212, and a fixing frame F213; the first driving device F211 is disposed on the connecting frame F221; the output end of the first driving device F211 is connected to the second driving device F212 and drives the second driving device F212 to move along the intersection direction of the extension directions of the first clamping structure F222 to the second clamping structure F223; the output end of the second driving device F212 is connected to the fixing frame F213 and drives the fixing frame F213 to move along the extension direction of the first clamping structure F222 to the second clamping structure F223, and the first clamping structure F222 is disposed on the fixing frame F213. Specifically, both the first driving device F211 and the second driving device F212 can be devices capable of driving linear movement, such as linear motors. Understandably, the extension direction of the first clamping structure F222 to the second clamping structure F223 can be the X-axis direction of the three-dimensional coordinate system, and the intersection direction of the extension directions of the first clamping structure F222 to the second clamping structure F223 is the Y-axis direction of the three-dimensional coordinate system. By setting the first driving device F211 and the second driving device F212 to cooperate in driving the first clamping structure F222, the distance of the first clamping structure F222 can be finely adjusted with the second clamping structure F223 as a fixed point, so as to flexibly and accurately clamp the PCB board. The fixing frame F213 can be a U-shaped frame, with the second clamping structure F223 located in the hollow position of the fixing frame F213. The first driving device F211 and the second driving device F212 are located on one side of the second clamping structure F223, while the first clamping structure F222 is located on the other side of the second clamping structure F223, to improve space utilization.

[0174] In some embodiments, the coil moving mechanism F21 includes a third driving device F214 and a fourth driving device F215. The third driving device F214 is mounted on the base A100. The output end of the third driving device F214 is connected to the fourth driving device F215 and drives the fourth driving device F215 to move along the extension direction from the second support portion D22 to the third support portion D14. The output end of the fourth driving device F215 is connected to the connecting frame F221 and drives the connecting frame F221 to move up and down in the height direction of the workstation plate A200. Specifically, both the third driving device F214 and the fourth driving device F215 can be devices capable of driving linear movement, such as linear motors. The extension direction of the second bearing part D22 to the third bearing part D14 can be the X-axis direction, and the height direction is the Z-axis direction of the three-dimensional coordinate system. Through the cooperation of the third driving device F214 and the fourth driving device F215, the two clamping structures can be driven to reciprocate between the second bearing part D22 and the third bearing part D14, and the two clamping structures can be driven to move up and down to perform clamping or releasing operations.

[0175] In some embodiments, the opposing side of the first clamping member F2232 and the second clamping member F2233 in the second clamping structure F223 is the clamping side, and the surface of the clamping side has an arc-shaped surface structure that adapts to the outer edge of the coil. Specifically, the clamping side of the two clamping members of the second clamping structure F223 is the side surface that contacts the coil during clamping. By having an arc-shaped clamping side, the clamping side of the two clamping members can match the shape of the outer edge of the coil, thereby better fitting the coil surface and effectively preventing coil deformation or damage.

[0176] In some embodiments, the first carrier D1 is suspended on the workstation plate A200 on the side near the first bearing part D11; the coil assembly device F10 also includes a support device F4 disposed below the workstation plate A200, the support device F4 includes a support drive device F41 and a support plate F42; the output end of the support drive device F41 is connected to the support plate F42 and drives the support plate F42 to move up and down, and the part of the carrier D10 suspended outside the base A100 is disposed opposite to the support plate F42. Specifically, the first carrier D1 is partially suspended from the work station plate A200 near the first support part D11. Since the suspended area is used to support the coil and PCB board, the partially suspended structure facilitates the soldering, cutting, and removal of waste wires of the coil and PCB board on the machine base A100. However, since the pushing device F1 exerts downward pressure on the second carrier D2 during the process of detaching the coil from the second support part D22, the support plate F42 is driven to move by the support drive device F41 to move upward to support the part of the first carrier D1 suspended on the frame, which can ensure the overall stability of the carrier D10.

[0177] Welding device E10:

[0178] like Figures 14 to 19 As shown, the welding device E10 includes a welding assembly E1, which includes a power supply, a welding drive device E11, and a welding head E12. An electrode E121 is provided on the welding head E12. The power supply is connected to the electrode E121. The output end of the welding drive device E11 is connected to the welding head E12 and drives the electrode E121 on the welding head E12 to move closer to or away from the first support part D11.

[0179] Specifically, during the welding operation, the PCB board is located on the first support part D11, and the coil is located on the second support part D22. The welding drive device E11 drives the welding head E12 to move the electrode E121 to a welding point on the PCB board on the first support part D11. The power supply outputs stable DC power or AC power. The power conversion device rectifies the input AC power into DC power, and then converts it into high-frequency current through the inverter circuit. Finally, a stable DC welding current is output and conducted through the electrode E121 to one of the welding points on the PCB board. The resistance heat generated when the current flows through the welding point on the PCB board welds one welding point on the PCB board to one end wire of the coil. After the welding point is completed, the welding drive device E11 drives the welding head E12 to move the electrode E121 to another welding point on the PCB board on the first support part D11. The current is guided to the welding point through the electrode E121, and the resistance heat generated welds the welding point on the PCB board to the other end wire of the coil, completing the welding operation.

[0180] Therefore, by setting adjacent first support part D11 and second support part D22 on the carrier D10, the two end wires of the coil can be precisely mounted on the two solder points of the PCB board when the coil and the PCB board are respectively supported by the two support parts. The welding component E1 outputs a stable DC welding current to the electrode E121 through the power supply E3. The resistance heat generated at the pressing point of the electrode E121 welds the solder point and the end wire of the PCB board together to complete the welding operation. Compared with the existing tin soldering method, the use of solder can be omitted, thereby effectively preventing the problem of solder melting and splashing everywhere during welding, improving the product appearance and welding quality.

[0181] In some embodiments, the welding apparatus E10 includes a clamping assembly E2. The clamping assembly E2 includes a clamping drive device E21 and a clamping member E22. The output end of the clamping drive device E21 is connected to the clamping member E22 and drives the clamping member E22 to move to clamp or release the workpiece on the first support portion D11. Specifically, during the welding operation, the PCB board is located on the first support portion D11, and the coil is located on the second support portion D22. The clamping drive device E21 drives the clamping member E22 to clamp the PCB board on the first support portion D11, and then the welding drive device E11 drives the welding head E12 to drive the electrode E121 to complete the welding operation.

[0182] In some embodiments, electrode E121 has a partition slit E122 along its axial direction, so that electrode E121 is isolated on both sides of the partition slit E122 to form an independent first electrode E1211 and a second electrode E1212. The power supply has a positive terminal and a negative terminal. The first electrode E1211 is connected to the positive terminal of the power supply, and the second electrode E1212 is connected to the negative terminal of the power supply. Specifically, the partition slit E122 is formed axially at the central axis of electrode E121 to isolate the two sides of electrode E121 into two independent structures. Current flows into the first electrode E1211, passes through the solder joints on the PCB board, and returns to the power supply through the second electrode E1212 to form a closed loop. The function of the partition slit E122 is to isolate the current paths on both sides, ensuring that energy is accurately applied to the solder joints on the PCB board.

[0183] In some embodiments, electrode E121 has a first side and a second side. The first and second sides of electrode E121 near its own end are inclined toward the central axis of electrode E121, so that the end of electrode E121 has a tapered structure. Since the soldering points of PCB board and copper wire are very small, the tapered tip design of electrode E121 can reduce the contact area, increase the current density, concentrate energy on the tiny solder joint, and further improve the soldering effect.

[0184] In some embodiments, the welding assembly E1 further includes a welding frame E13 and a first clamping arm E14 and a second clamping arm E15 disposed on the welding frame E13; the output end of the welding drive device E11 is connected to the welding frame E13 and drives the welding frame E13 to move closer to or away from the first support portion D11, and the first clamping arm E14 and the second clamping arm E15 together clamp the welding head E12. It should be noted that the welding head E12 is cylindrical, and the electrode E121 is also cylindrical, with the electrode E121 fixed to the bottom end of the welding head E12. By setting two clamping arms to jointly clamp the welding head E12, the clamping effect of the welding head E12 can be improved, and the contact point position between the electrode E121 and the PCB board can be fixed, avoiding displacement caused by mechanical vibration or pressure changes during the welding process.

[0185] In some embodiments, the second clamping arm E15 is movably connected to the welding frame E13; the welding assembly E1 also includes an adjustment mechanism E16, which is connected to the second clamping arm E15. The adjustment mechanism E16 adjusts the position of the second clamping arm E15 to adjust the clamping distance between the second clamping arm E15 and the first clamping arm E14. Understandably, precisely adjusting the clamping distance between the first clamping arm E14 and the second clamping arm E15 through the adjustment mechanism E16 not only ensures stable clamping of the workpiece during welding, avoiding welding deviations or workpiece damage due to insecure clamping, but also makes it easier to replace or disassemble the welding head E12 for maintenance, eliminating the need for complex disassembly and assembly operations on the entire welding assembly E1. Of course, in other embodiments, this adjustment structure can also be connected to the first clamping arm E14 and the second clamping arm E15 to simultaneously adjust the positions of both arms to adjust the clamping distance between them; no particular limitation is made here.

[0186] Specifically, in this embodiment, the adjusting mechanism E16 includes a guide rod E161, a slider E162, and an adjusting screw E163. The guide rod E161 is mounted on the welding frame E13 along the moving direction of the second clamping arm E15. The second clamping arm E15 is slidably mounted on the guide rod E161 via the slider E162. The adjusting screw E163 is rotatably mounted on the welding frame E13 and is threadedly connected to the slider E162. Specifically, when a user applies force to the adjusting screw E163, the adjusting screw E163 rotates, thereby causing the slider E162 to slide left and right along the guide rod E161, achieving the effect of moving the second clamping arm E15 relative to the welding frame E13, thus quickly adjusting the clamping distance between the first clamping arm E14 and the second clamping arm E15.

[0187] In some embodiments, the end of the clamping member E22 has a tapered structure. To improve the clamping effect on the PCB board, the clamping member E22 is pressed between two solder joints on the PCB board. Since the PCB board is a small PCB board, the tapered tip design of the clamping member E22 reduces the contact area, effectively avoiding interference with the soldering operation of the solder joints.

[0188] In some embodiments, the welding drive device E11 includes a first welding drive element E111 and a second welding drive element E112. The output end of the first welding drive element E111 is connected to the second welding drive element E112 and drives the second welding drive element E112 to move along the extension direction of the two welding points on the PCB board. The output end of the second welding drive element E112 is connected to the welding head E12 and drives the welding head E12 to move closer to or further away from the first support portion D11 in the height direction. Both the first welding drive element E111 and the second welding drive element E112 can be linear drive devices such as linear motors or linear modules. Specifically, in this embodiment, the two welding points on the PCB board are laterally distributed. Similarly, the driving direction of the first welding drive element E111 is also adapted to be laterally, and the driving direction of the second welding drive element E112 is vertical, to cooperate in forming a two-dimensional motion drive device to drive the electrode E121 to perform welding operations at different welding points. Of course, in other embodiments, the welding drive device E11 can also be a three-axis motion platform or other multi-axis motion platform, without particular limitation.

[0189] PCB board loading device H10:

[0190] like Figure 26 As shown, the PCB board loading device H10 includes a punching mechanism H1, a punching conveyor mechanism H2, and a transfer device. The punching mechanism H1 includes a punching module H11 and a punching table H12; the punching conveyor mechanism H2 is disposed between the punching module H11 and the workstation A200, and the punching table H12 is disposed on the punching conveyor mechanism H2 and is moved by the punching conveyor mechanism H2; the transfer device cooperates with at least the punching conveyor mechanism H2 and the workstation A200. The punching module H11 is a conventional structure capable of punching PCB boards. Through the cooperation of high-precision molds and stamping machinery, high pressure is applied in a short time to cut the PCB board into blocks of a specific shape. The PCB board is placed on the punching table H12. The punching conveyor, such as a linear motion module, adjusts the PCB board to align with the bottom of the punching module H11. The punching module H11 cuts the PCB board into multiple block-shaped PCB boards of a specific shape. Specifically, in this embodiment, the punching module H11 punches the PCB board in three stages to cut it into 195 individual PCB boards. Subsequently, the punching conveyor transports the punching table H12 and the cut PCB boards to one side near the workstation A200. The transfer device sequentially loads the PCB boards onto the carrier D10 of the workstation A200, wherein the transfer device is a conventional robotic arm structure.

[0191] In some embodiments, the PCB board loading device H10 further includes a storage device H3 and a suction device H4. The storage device H3 includes a storage body with a storage slot. A lifting drive device and a lifting push rod H31 connected to the lifting drive device are disposed within the storage slot. The PCB board is placed in the storage slot and positioned on the lifting push rod H31. The lifting drive device drives the lifting push rod H31 to rise, pushing the PCB board to a preset position so that the suction device H4 can pick up the PCB board and transfer it from the storage slot to the punching table H12. The storage slot can automatically fill empty spaces after a previous PCB board is removed. The suction device H4 includes a suction drive module and a suction cup. The suction drive device drives the suction cup to move between the punching table H12 and the storage slot.

[0192] In some embodiments, the punching mechanism H1 further includes a centering and shaping mechanism; the centering and shaping mechanism includes a shaping block and a side-push shaping assembly; the shaping block has a shaping groove for placing the punched PCB board, and the side-push shaping assembly includes a first abutment block, a second abutment block and a side-push driving device; the first abutment block and the second abutment block are disposed on opposite sides of the shaping groove, the output end of the side-push driving device is connected to the second abutment block and drives the second abutment block to move closer to or away from the first abutment block, and the transfer device has two jaws for gripping the PCB board, and the two jaws of the transfer device cooperate with the first abutment block and the second abutment block to center and shape the four sides of the PCB board. When the transfer device clamps the PCB board into the shaping groove, the first and second abutting blocks are located on the left and right sides of the PCB board, and the two grippers of the transfer device are located on the front and rear sides of the PCB board. Therefore, by driving the second abutting block relative to the first abutting block through the side push drive device, the position of the PCB board in the left and right directions can be shaped. By clamping the two grippers of the transfer device with each other, the position of the PCB board in the front and rear directions can be shaped. Therefore, by cooperating with the first and second abutting blocks, the two grippers of the transfer device can center and shape the four sides of the PCB board. After the PCB board is centered and shaped, it is transferred to the carrier D10 of the workstation tray A200, so that the PCB board can be accurately transferred to the first bearing part D11 of the carrier D10. The groove shape of the shaping groove is consistent with the bearing position shape of the first bearing part D11 of the carrier D10.

[0193] In some embodiments, a waste collection device H5 is also provided on one side of the punching conveyor H2. The suction device H4 moves between the punching table H12 and the waste collection device H5 to transfer the waste material after punching the PCB board from the punching table H12 to the waste collection device H5.

[0194] Vibrating plate B10:

[0195] like Figures 37 to 41As shown, the first end of the housing B100 of the ring RFID chip is an arched part B110, and the second end is a circular part B120. The diameter of the arched part B110 is smaller than the diameter of the circular part B120.

[0196] With the direction of travel of the housing B100 as forward, the directional arrangement in this embodiment results in the arched portion B110 of the housing B100 facing forward. This embodiment improves upon the existing spiral feeding track B200 of the vibratory feeder, such as... Figure 2 As shown, the spiral feeding track B200 conveys the housing B100 spirally upwards from the bottom of the vibratory feeder. To orient these housings B100 during loading, a screening track B210 is provided within the spiral feeding track B200. Housings B100 with their arched portions B110 facing backwards fall into the vibratory feeder's trough as they pass through the screening track B210, then re-enter the spiral feeding track B200. Only housings B100 with their arched portions B110 facing forwards can pass through the screening track B210 for use by the automated assembly line. The spiral feeding process of the spiral feeding track B200 and the structure of the vibratory feeder are conventional technologies in the field and will not be described in detail here.

[0197] Specifically, such as Figure 3 As shown, the screening track B210 in this embodiment has an L-shaped cross-section, including a first wall B211 and a second wall B212. The width of the first wall B211 is smaller than the width of the second wall B212. For ease of description, with the shell B100 placed in a planar position as a reference, the top and bottom walls of the shell B100 are collectively referred to as the planar wall B130, and the annular sidewall of the shell B100 is referred to as the vertical wall B140. When the shell B100 moves on the screening track B210, the vertical wall B140 of the shell B100 abuts against the first wall B211, and the planar wall B130 of the shell B100 abuts against the second wall B212.

[0198] To filter out incorrectly oriented housing B100, a notch can be made in the second wall. A baffle is provided between the bottom edge of the notch and the bottom edge of the second wall, and a horn is provided above the notch. Furthermore, the two ends of the notch have different dimensions. For example, to filter out housing B100 with the arched portion B110 facing backwards, the dimension of the first end of the notch at the rear is smaller than the dimension of the second end at the front; conversely, to filter out housing B100 with the arched portion B110 facing forwards, the dimension of the first end of the notch at the rear is larger than the dimension of the second end at the front. By providing the baffle, the horn, and the different dimensions of the first and second ends, it is ensured that only correctly oriented housing B100 can pass through the notch.

[0199] Specifically, in this embodiment, a quadrilateral notch B213 is cut out on the second wall B212. The bottom of the notch B213 has a first included angle B2131 and a second included angle B2132, and the top has a third included angle B2133 and a fourth included angle B2134. The second included angle B2132 is located in front of the first included angle B2131. The first included angle B2131 is an acute angle, the second included angle B2132 is an obtuse angle, and the fourth included angle B2134 is an acute angle, forming an angle on the second wall B212. The distance between the vertices of the second included angle B2132 and the fourth included angle B2134 is greater than the diameter of the circular portion B120 of the shell B100, and a retaining strip B214 is provided between the bottom edge of the second wall B212 and the bottom edge of the notch B213. If the arched portion B110 faces forward, when the housing B100 reaches the notch B213, the arched portion B110 of the housing B100 abuts against the stop bar B214, and part of the circular portion B120 of the housing B100 abuts against the stop bar B214 and part against the corner. At this time, the housing B100 will not fall off the notch B213. As the housing B100 continues to move, the circular portion B120 of the housing B100 disengages from the corner. At this time, the arched portion B110 of the housing B100 abuts against the second wall B212 in front of the second included angle B2132. Furthermore, a portion of the circular portion B120 adjacent to the arched portion B110 also abuts against the second wall B212 in front of the second included angle B2132, preventing the shell B100 from falling off the notch B213. However, if the arched portion B110 faces backward, since the first included angle B2131 is an acute angle and is located behind the second included angle B2132, when the shell B100 travels to a certain position in the notch B213, the shell B100 will only abut against the stop bar B214. At this point, under the influence of gravity, the shell B100 will fall off the notch B213. Therefore, directional feeding of the shell B100 is achieved.

[0200] To prevent the arched portion B110 from impacting the rearward-facing shell B100 when the shells B100 are arranged adjacently and passing through the notch B213, causing the rearward-facing shell B100 to also pass through the notch B213 smoothly, this embodiment provides two notches B213 spaced apart on the second wall B212, improving the reliability of the directional arrangement and feeding of the shells B100. Obviously, the specific number of notches is not limited, and there can be two or more.

[0201] To ensure that multiple housings B100 do not stack when traveling on the screening track B210, the screening track B210 is designed with inclined walls, at least at the notch B213, such that the first wall B211 is inclined outward and the second wall B212 is inclined inward. "Outward" and "inward" refer to the exterior or interior of the vibrating disk, respectively. In this embodiment, at the entrance of the screening track B210, the second wall B212 is horizontally positioned. Near the notch B213, the second wall B212 is inclined inward, meaning the end of the second wall B212 facing the vibrating disk is higher than the end facing away from the vibrating disk. From the entrance B215 to the notch B213, at least a portion of the screening track B210 gradually twists outward. By twisting at least part of the screening track B210 from a horizontal state to an outward tilted state, if the housings B100 are stacked, the screening track B210 is tilted, and only one housing B100 can be supported by the first wall B211 and the second wall B212, while the other housings B100 will fall off, ensuring that the housings B100 are fed one by one.

[0202] In some embodiments, after the screening track B210 is twisted outward, it remains tilted until its outlet B216, facilitating the processing of the screening track B210. For example... Figure 4 As shown, the outlet B216 of the screening track B210 is located on the discharge platform B220. The discharge platform B220 is horizontally arranged, and the inner end of the discharge platform B220 is connected to the discharge channel B221. At the outlet B216 of the screening track B210, the screening track B210 is vertically arranged. The discharge platform B220 is inclined inward, that is, the height of the end of the discharge platform B220 away from the center of the vibratory feeder is greater than the height of the end closer to the center of the vibratory feeder, so that the housing B100 can tilt after traveling to the discharge platform B220, changing from a vertical to a horizontal position. In order to effectively tilt the housing B100, a long lever B222 is installed on the discharge platform B220 at the outlet B216 of the screening track B210. The axial direction of the lever B222 is parallel to the extension direction of the outlet B216 of the screening track B210. That is, when the housing B100 slides out of the outlet B216 of the screening track B210, the bottom of the housing B100 abuts against the lever B222. Since the discharge platform B220 is tilted inward, the lever B222 causes the housing B100 to tilt to a horizontal position and slide to the inside of the discharge platform B220.

[0203] Because the shells B100 can take on various shapes on the screw feed track, such as stacked together, one shell B100 partially resting on another, or two shells B100 standing side by side, etc., to ensure the shells B100 are arranged sequentially, the shape of the shells B100 entering the screening track B210 is made more consistent with expectations. An L-shaped conveyor track B230 and a conveyor table B240 are also installed on the screw feed track. For example... Figure 2 and Figure 5 As shown, the conveyor platform B240, the conveyor track B230, and the screening track B210 are connected in sequence. The conveyor platform B240 is horizontally arranged, and the housing B100 is in a horizontal state when it enters the conveyor platform B240. The conveyor track B230 has a third wall B231 and a fourth wall B232. The width of the third wall B231 is smaller than the width of the fourth wall B232. The vertical wall B140 of the housing B100 abuts against the third wall B231, and the planar wall B130 of the housing B100 abuts against the fourth wall B232. Furthermore, at least a portion of the conveyor track B230 gradually twists outward, causing at least a portion of the conveyor track B230 to be inclined, thereby causing the housing B100 to gradually change from a horizontal state when it enters the conveyor platform B240 to an inclined state. The outer side of the conveyor track B230 is connected to the outer side of the conveyor platform B240. At least the part of the conveyor platform B240 adjacent to the conveyor track B230 is tilted outward, so that the housing B100 on the conveyor platform B240 slides to the outer side and thus smoothly moves to the conveyor track B230.

[0204] The purpose of tilting the conveyor track B230 and the screening track B210 is to prevent the housing B100 from stacking or overlapping. Therefore, the width of the third wall B231 and the first wall B211 should not be too wide or too narrow. The ratio between the width of the third wall B231, the width of the first wall B211 and the thickness of the housing B100 is between 0.8 and 1.2. Preferably, the width of the third wall B231 and the width of the first wall B211 are approximately equal to the thickness of the housing B100.

[0205] In some embodiments, the conveying track B230 and the screening track B210 are spirally descending tracks, and the height of the conveying track B230 is higher than that of the screening track B210. The housing B100 can also slide down using gravity while traveling on the conveying track B230 and the screening track B210, making the travel smoother.

[0206] In this embodiment, after the conveyor track B230 becomes inclined, the housing B100 maintains its inclined position until it reaches the outlet B233 of the conveyor track B230. The housing B100 at the inlet B215 of the screening track B210 is horizontal; therefore, an L-shaped screening table B250 is also provided. The screening table B250 is horizontally positioned, and the outlet of the conveyor track B230 is located in the middle of the screening table B250. Since the outlet B233 of the conveyor track B230 is inclined relative to the screening table B250, when the housing B100 slides from the outlet B233 of the conveyor track B230 to the screening table B250, without the clamping of the third wall B231 and the fourth wall B232, it will lie down, changing from an inclined position to a horizontal position.

[0207] The screening track B210 connects to the outer side of the screening table B250. A sliding section B251 is formed on the screening table B250 between the screening track B210 and the conveying track B230. The sliding section B251 is inclined outwards, meaning the height of the end of the sliding section B251 near the center of the vibrating plate is greater than the height of the end away from the center of the vibrating plate. This allows the housing B100 to automatically slide to the outer side on the sliding section B251, smoothly entering the screening track B210.

[0208] In order to allow more of the arched portion B110 of the housing B100 to face forward at the exit of the conveyor track B230, at the exit B233 of the conveyor track B230, the third wall B231 of the conveyor track B230 widens, that is, it extends in a direction away from the fourth wall B232 to form a side wing B234. Furthermore, the side wing B234 protrudes from the exit B233 of the conveyor track B230, and the bottom of the front end of the side wing B234 has a sharp corner B2341. When the arched portion B110 slides along the side wing B234 with the rearward-facing shell B100, the circular portion B120 is in front. When the pointed corner B2341 abuts at the intersection of the circular portion B120 and the arched portion B110, the center of gravity of the shell B100 protrudes beyond the pointed corner B2341. As the circular portion B120 slides outward, the pointed corner B2341 acts as a fulcrum, causing most of these shells B100 to deflect, changing from the arched portion B110 facing rearward to the arched portion B110 facing forward. As for the shell B100 with the arched part B110 facing forward, when it slides along the side wing B234, even when the arched part B110 is completely protruding from the sharp corner B2341, the center of gravity of the shell B100 is still within the range of the side wing B234. The side wing B234 still supports the shell B100, and most of the shell B100 is not affected by the sharp corner B2341 and will not deflect.

[0209] To ensure that the housing B100 becomes horizontal when sliding from the outlet B233 of the conveyor track B230 to the screening table B250, this embodiment also cuts the fourth wall B232 of the conveyor track B230 at the outlet B233: first longitudinally and then obliquely, forming a cut B235. The cut B235 has a first side B2351 and a second side B2352. The angle between the first side B2351 and the second side B2352 is obtuse, and the second side B2352 forms a sharp angle with the bottom edge of the fourth wall B232. When the housing B100 slides to the position of the cut B235, part of the housing B100 overlaps the screening table B250, and the other part overlaps the fourth wall B232 behind the sharp angle, preventing the housing B100 from rolling on the screening table B250. As it continues to move, another part falls from the sharp corner onto the screening table B250, the shell B100 becomes horizontal, and the flat wall B130 abuts against the screening table B250.

[0210] In summary, the vibratory feeder of this embodiment filters shells whose orientation does not meet expectations through the notches in the screening track, and sets up a conveyor track. The conveyor track twists outwards to pre-filter stacked shells, arranging them one by one. A screening platform is set at the connection between the screening track and the conveyor track, tilting outwards. A side wing with a sharp angle is provided at the exit of the conveyor track to deflect shells whose arched portions are facing backwards, changing them to face forwards. This achieves forward-oriented directional feeding of the shells, facilitating subsequent processing steps.

[0211] Tangent device J10:

[0212] like Figure 28 As shown, the wire cutting device J10 includes a wire cutting bracket J1, a cutter drive device J2, and a cutter J3 connected to the cutter drive device J2. The wire cutting bracket J1 is mounted on the machine base A100, the cutter drive device J2 is mounted on the wire cutting bracket J1, and the cutter J3 is correspondingly mounted above the workstation A200. When the workstation A200 rotates, moving the soldered carrier D10 below the wire cutting device J10, the cutter J3 is aligned with the waste wire area adjacent to the solder joint on the PCB board. The cutter drive device J2, such as a lifting motor, moves the cutter J3 downwards to cut the soldered coil waste wire.

[0213] In some embodiments, the wire cutting device J10 further includes a wire cutting guide rod J4, a wire cutting slide J5, and a wire cutting elastic element J6. The wire cutting guide rod J4 is disposed on the wire cutting bracket J1, the wire cutting slide J5 is slidably disposed on the wire cutting guide rod J4, the cutter J3 is disposed on the wire cutting slide J5, the output end of the cutter driving device J2 is connected to the wire cutting slide J5, and the wire cutting bracket J1 is connected to the wire cutting slide J5 through the wire cutting elastic element J6. The sliding cooperation between the wire cutting guide rod J4 and the wire cutting slide J5 enables the cutter J3 to move stably up and down, and the wire cutting elastic element J6, such as a spring, can buffer the cutter J3, effectively preventing excessive cutting force from damaging the PCB board.

[0214] In some embodiments, the tangent support J1 is further provided with a tangent positioning sensor. When the tangent positioning sensor detects that the carrier D10 has reached the tangent position of the tangent device J10, the cutter J3 is activated to cut off the waste wire of the coil.

[0215] Waste wire clamping device K10:

[0216] like Figure 27 As shown, the waste wire clamping device K10 includes a waste wire clamping drive device K1, a waste wire clamping component K2, a waste wire pushing drive device K3, and a waste wire pushing rod K4. The waste wire clamping component K2 has a waste wire clamping space. The output end of the waste wire clamping drive device K1 is connected to the waste wire clamping component K2 and drives the waste wire clamping component K2 to move and rotate. The output end of the waste wire pushing drive device K3 is connected to the waste wire pushing rod K4 and drives the waste wire pushing rod K4 to extend into or out of the waste wire clamping space of the waste wire clamping component K2. Specifically, the waste wire clamping component K2 is a conventional pneumatic gripper or electric gripper, etc., capable of clamping and cutting coil waste wire. No special restrictions are made here. The two grippers cooperate to form the waste wire clamping space. The waste wire clamping component K2 is located on the outside of the workstation plate A200. The waste wire clamping drive device K1 drives the waste wire clamping component K2 to move back and forth, so as to insert into the position of the carrier D10 to clamp the waste wire ends wrapped on the two end posts D23 on the carrier D10 and detach the waste wire ends from the end posts D23. Then, the waste wire clamping drive device K1 drives the jaws of the waste wire clamping component K2 to rotate, so that the jaws that are distributed vertically rotate to the left and right distributed jaws. Then, the two jaws open to expand the waste wire clamping space. The waste wire pushing drive device K3, such as a lifting cylinder, drives the waste wire pushing rod K4 to descend and extend into the waste wire clamping space between the two jaws, thereby pushing the waste wire ends on the jaws away so that the waste wire ends fall into the waste wire end storage box below. Specifically, the waste wire clamping drive device K1 includes a linear module and a rotary motor. The output end of the linear module is connected to the rotary motor and drives the rotary motor to move closer to or further away from the two end posts D23 of the carrier D10 along the lateral direction of the workstation plate A200. The output end of the rotary motor is connected to the waste wire clamping component K2.

[0217] Coil shaping device L10:

[0218] like Figure 27 As shown, the RFID chip automatic assembly equipment 1000 also includes a coil shaping device mounted on the base A100.

[0219] L10; The coil shaping device L10 is located on the inner side of the machine base A100 corresponding to the workstation plate A200, and is positioned opposite to the waste wire clamp K2. The coil shaping device L10 includes a shaping bracket L1, a shaping drive device L2, and a shaping head L3. The shaping drive device L2 is mounted on the shaping bracket L1, which is mounted on the machine base A100. The shaping head L3 is shaped to fit the structure of the coil and PCB board, and is configured as a shaping ring and a square clamp connected to the shaping ring. The shaping ring and the square clamp are arranged side-by-side. The output end of the shaping drive device L2 is connected to the shaping head L3 and drives the shaping head L3 to move up and down to extend into or out of the carrier D10. After the coil and PCB board are assembled into the housing, the shaping head L3 compresses and shapes the coil and PCB board to ensure accurate assembly within the housing.

[0220] In some embodiments, a spring is provided between the shaping head L3 and the shaping bracket L1 to buffer the shaping head L3 and effectively prevent the excessive squeezing force of the shaping head L3 from damaging the coil and PCB board.

[0221] Detection device M10;

[0222] like Figure 29 As shown, the detection device M10 is mounted on the base A100 and is used to detect the assembly status of the assembled RFID chips. The detection device M10 includes a detection bracket M1, a detection lifting drive device M2, and a detection module M3. The detection bracket M1 is mounted on the base A100, and the detection lifting drive device M2 is mounted on the detection bracket M1. The output end of the detection lifting drive device M2 is connected to the detection module M3 and drives the detection module M3 to move up and down. When the workstation plate A200 rotates, driving the carrier D10 carrying the assembled RFID chips to the area where the detection device M10 is located, the detection lifting drive device M2 (such as a lifting motor) drives the detection module M3 to descend to the position of the carrier D10. Through the detection module M3, the assembly status of the assembled RFID chips is detected without contact to determine if it is qualified.

[0223] Palletizing equipment:

[0224] To achieve automatic palletizing of the product conveyor line and improve its efficiency, a palletizing device is designed when the assembled RFID chips are detected as qualified. This automatic RFID chip assembly equipment also includes a feeding robot that moves between the workstation tray and the palletizing device. When the assembled RFID chips are detected as qualified, the workstation tray rotates, causing the carrier to move to the area where the palletizing device is located. Then, the feeding robot picks up the assembled RFID chips and places them sequentially into the storage location of the workstation tray.

[0225] This palletizing device can automatically depalletize pallets at the loading position and automatically stack pallets at the unloading position. Depalletizing at the loading position refers to the process of removing pallets from a neatly stacked pile of empty or raw material pallets in a specific order and conveying them to a designated location on the production line. Pallet stacking at the unloading position refers to the process of stacking pallets containing finished products after processing or assembly at the unloading position for subsequent centralized storage or transportation. By integrating pallet stacking and depalletizing into the product conveyor line, the efficiency of the product conveyor line can be improved, and the need for manual or robotic arm handling of individual pallets can be eliminated, reducing production costs.

[0226] like Figures 30 to 36 As shown, the palletizing device includes a tray support G10 and a tray moving assembly G20. The tray support G10 can be part of or part of the entire product conveyor line. The tray support G10 is rectangular, with an upper tray position G11 and a lower tray position G12 at its two ends. At the upper tray position G11, a first stack G13 formed by stacking empty or raw material-filled trays is placed on the tray support G10; at the lower tray position G12, a second stack G14 formed by stacking product-filled trays is placed on the tray support G10. The tray support G10 is openwork, and the tray moving assembly G20 is located below the tray support G10 and can slide horizontally between the upper tray position G11 and the lower tray position G12. A tray is unpacked from the first pallet G13 and transported to the processing station via the tray moving assembly G20 along the tray support G10. The processed product is placed in the tray, and then the tray is transported to the unloading tray position G12 via the tray moving assembly G20. This tray is then stacked together with the trays in the second pallet G14 to form a new second pallet G14. It should be noted that although the tray support G10 between the upper tray position G11 and the lower tray position G12 is straight in this embodiment, it is not limited to this. The tray support G10 can also have corners or bends, which can be set according to the requirements of the product conveyor line.

[0227] In this embodiment, the tray G30 is a square tray with a positioning post G31 at each of the four top corners and a groove (not shown in the figure) at each of the four bottom corners. The positioning posts G31 and the grooves allow two trays G30 to be stacked together. It should be noted that the shape of the tray G30 can also be a triangular or polygonal tray, and the specific shape is not limited.

[0228] To enable automatic destacking at the loading tray position G11 and automatic stacking at the unloading tray position G12, a tray lifting assembly G40 and four stacking support assemblies G50 are provided at both the loading tray position G11 and the unloading tray position G12. The tray lifting assembly G40 is installed on the inner side of the tray support G10, located between the two stacking support assemblies G50. The tray lifting assembly G40 is used to destacking a tray G30 from the first stack 11 at the loading tray position G11; and at the unloading tray position G12, to stack the tray G30 together with the tray G30 in the second stack G14 to form a new second stack G14. The palletizing support assembly G50 is mounted on the pallet bracket G10, and the vertical gap between it and the pallet lifting assembly G40 is greater than the height of one pallet G30. That is, at the unloading position G12, the pallet moving assembly G20 can transport one pallet G30 into the gap between the pallet lifting assembly G40 and the palletizing support assembly G50; and at the loading position G11, the pallet lifting assembly G40 can unload one pallet G30 from the first pallet G13 into the gap between the pallet lifting assembly G40 and the palletizing support assembly G50.

[0229] Specifically, the tray lifting assembly G40 includes two lifting mechanisms G41, which are symmetrically distributed on both sides of the frame 10. Each lifting mechanism G41 includes a cylinder G411 and a lifting platform G412. The lifting platform G412 is plate-shaped and fixed to the output end of the cylinder G411. Driven by the cylinder G411, the lifting platform G412 can move up and down, thereby stacking the trays G30 into the second stack G14 or removing a tray G30 from the first stack G13. Obviously, the tray lifting assembly G40 can also include three lifting mechanisms G41, which are respectively abutted against the three sides of the tray G30, thereby driving the tray G30 to rise or fall at three positions.

[0230] The palletizing support assembly G50 is movably mounted on the frame 10 and has a first position and a second position. In the first position, the palletizing support assembly G50 is disengaged from the first pallet G13 or the second pallet G14. In the second position, the palletizing support assembly G50 at least partially abuts against the lower surface of the first pallet G13 or the second pallet G14. The palletizing support assembly G50 cooperates with the tray lifting assembly G40 to realize the palletizing and depalletizing of the tray G30. Specifically, at the loading tray position G11, the tray lifting component G40 rises, supporting the first stack G13, and the stacking support component G50 is controlled to the first position. Then, the tray lifting component G40 drives the first stack G13 to descend. When the distance the first stack G13 descends is equal to the sum of the height of one tray G30 and the gap distance between two trays G30, the stacking support component G50 is controlled to the second position. At this time, the stacking support component G50 abuts against the lower surface of the second-to-last tray (the direction from the bottom of the stack to the top is the reciprocal direction), preventing the second-to-last tray from descending further. At this time, the first-to-last tray is not restricted, and the tray lifting component G40 continues to descend, driving the first-to-last tray to continue descending, thereby separating one tray G30 from the first stack G13; at the unloading tray... Position G12: The tray moving component G20 moves the tray G30 containing the finished product to the unloading tray position G12. Then, the tray lifting component G40 raises the tray G30 until it engages with the last tray in the second stack G14. At this point, the stacking support component G50 is moved to the first position, and the tray lifting component G40 continues to rise, lifting the second stack G14. When the distance the second stack G14 is raised is equal to the sum of the height of one tray G30 and the gap between the two trays G30, the stacking support component G50 is moved to the second position. At this point, the stacking support component G50 abuts against the lower surface of the last tray, supporting the second stack G14. Then, the tray lifting component G40 descends to the initial position, waiting for the tray moving component G20 to bring the next tray G30.

[0231] The palletizing support assembly G50 includes a base G51 and a support member G52. Specifically, the base G51 has a first plate G511 and a second plate G512 disposed opposite to each other, with a clearance groove G53 formed between the first plate G511 and the second plate G512. The support member G52 is embedded in the clearance groove G53. Bearings G54 are mounted on both the first plate G511 and the second plate G512. The support member G52 has a fixed shaft G56, which is rotatably connected to the bearings G54. Thus, the support member G52 is rotatably mounted on the base G51, so that the palletizing support assembly G50 has a first position (i.e., the top of the support member is parallel to the horizontal plane) and a second position (i.e., the top of the support member is inclined). A second elastic member G55 is also mounted on the side of the support member G52 facing the pallet bracket G10. The second elastic member G55 is located below the fixed shaft G56. When the top of the control support member G52 tilts, the second elastic member G55 is compressed, and the four palletizing support assemblies G50 are pushed outwards towards the tray support G10, allowing the tray G30 to move up and down without obstruction. When it is necessary to support the first pallet G13 or the second pallet G14, the second elastic member G55 returns to its original position, making the top of the support member G52 horizontal. The support member G52 then abuts against the bottom surface of the first pallet G13 or the second pallet G14, allowing the first pallet G13 or the second pallet G14 to be stably supported on the palletizing support assembly G50. It should be noted that the palletizing support assembly is not limited to the rotating structure of this embodiment; it can also be a sliding structure, such as a sliding structure that can slide inwards and outwards from the tray support G10.

[0232] The material tray moving assembly G20 includes a belt conveyor G21, a slide rail G22, and a second moving component G23. The second moving component G23 is mounted on the slide rail G22. The belt conveyor G21 can drive the second moving component G23 to move horizontally reciprocally. It should be emphasized that the horizontal reciprocating movement is not limited to horizontal linear movement, as long as the material tray G30 can be moved horizontally between the upper tray position G11 and the lower tray position G12. Specifically, there are two slide rails G22 spaced apart, extending along the longitudinal direction of the material tray support G10, and sliders G221 are mounted on the slide rails G22. The belt conveyor G21 includes a motor G211, a pulley G212, and a belt G213. The belt conveyor G21 is a conventional device in the art and will not be described in detail here. The bottom of the second moving part G23 has two bases G231 and a slot G232. One base G231 is fixed on a slider G221. The slot G232 has serrations, and part of the belt G213 of the belt conveyor device G21 is clamped and fixed in the slot G232. The motor G211 drives the pulley G212 to rotate, and the second moving part G23 is clamped and fixed on the belt G213. Thus, when the belt G213 moves back and forth, it drives the second moving part G23 to move back and forth.

[0233] In this embodiment, the top of the second moving member G23 is provided with a positioning pin G233, and the middle array of the tray G30 is provided with multiple through slots G32. The positioning pin G233 is inserted into the through slot G32, thereby causing the second moving member G23 to move, which in turn moves the tray G30. Obviously, the tray G30 may not have through slots G32, but at least multiple blind holes are arranged in the bottom array to form positioning grooves, thereby moving the tray through the cooperation of the positioning grooves and the positioning pins. Preferably, multiple through slots / blind holes are provided, making the control of the tray moving component G20 simpler and more convenient.

[0234] To ensure smoother and more reliable movement of the pallets during stacking and destacking, this embodiment includes a pallet support platform G60 mounted on the pallet bracket G10. Specifically, the pallet bracket G10 has a first side and a second side extending longitudinally. A first support plate G61 is mounted on the inner side of the first side, and a second support plate G62 is mounted on the inner side of the second side. The first support plate G61 and the second support plate G62 are at the same height, together forming the pallet support platform G60. When the pallet G30 moves, its bottom surface abuts against the first support plate G61 and the second support plate G62. It is easily understood that the first support plate G61 and the second support plate G62 can also be mounted on the outer side of the pallet bracket G10 as needed.

[0235] In some embodiments, when the second moving member G23 can stably support the tray G30 and move the tray G30, the tray support platform G60 may not be required. However, since the upper tray position G11 and the lower tray position G12 involve the stacking and destacking of the tray G30, it is preferable to provide the tray support platform G60 at the upper tray position G11 and the lower tray position G12. Furthermore, the top of the tray support platform G60 needs to be flush with the top of the tray lifting assembly G40 in its initial position so that the tray G30 can remain stable in these two positions.

[0236] To ensure the safety and stability of the palletizing, this embodiment also includes clamping components G70 at the loading tray position G11 and the unloading tray position G12. Specifically, the clamping component G70 includes four uprights G71, which are fixed to the tray support G10. All the uprights G71 enclose the palletizing space, and all the uprights G71 limit the palletizing at the four corners. Obviously, the number of uprights G71 is not limited to four; it can also be three, five, etc.

[0237] In summary, in this embodiment, by controlling the palletizing support assembly to switch between a first position and a second position, the pallet lifting assembly drives the pallet and pallet to rise or fall. This, in conjunction with the pallet lifting assembly, enables the unloading of pallets from the first pallet at the upper pallet position and the stacking of pallets into the second pallet at the lower pallet position. This eliminates the need to move pallets one by one to the upper pallet position and to remove them one by one from the lower pallet position for palletizing, thus improving production line efficiency and reducing production costs.

[0238] A specific workflow of the RFID chip automatic assembly equipment 1000 includes the following:

[0239] The PCB board loading device H10 punches and cuts PCB materials to obtain multiple individual PCB boards, and then conveys and transfers them to the first support part D11 of the first carrier D1 located on the work station tray A200;

[0240] Rotate the workstation plate A200 to rotate the carrier carrying the PCB board to the corresponding position of the vibratory feeder. The vibratory feeder automatically feeds and screens the shells, so that the arched parts of the individual shells are oriented forward and then transferred to the third bearing part D14 of the first carrier D1.

[0241] Rotate workstation A200 to move the carrier D10, which carries the PCB board and housing, to the winding machine C10. Transfer the second carrier D2 on the carrier D10 to the first heating device C3. The first heating device C3 heats the second carrier part D22 of the second carrier D2. Then, load it onto the winding machine C10. The winding machine C10 winds the second carrier part D22 of the second carrier D2 to obtain a coil. At the same time, the second heating device C4 heats the second carrier part D22. After winding, load the second carrier D2 onto the first carrier D1 of workstation A200.

[0242] Rotate the workstation plate A200 to transfer the carrier D10, which carries the PCB board, housing and coil, to the welding device E10. The welding device E10 welds the two solder points of the PCB board and the two end wires of the coil together on the carrier D10.

[0243] Rotate the workstation plate A200 to transfer the welded carrier D10 to the wire cutting device J10, which cuts off the waste wire of the welded coil.

[0244] Rotate the workstation plate A200 to transfer the cut-wire carrier D10 to the coil assembly device F10. The coil assembly device F10 smoothly detaches the coil from the second carrier part D22 and transfers the coil and PCB board to the housing of the third carrier part D14 to complete the assembly.

[0245] Rotate the workstation plate A200 to transfer the assembled carrier D10 between the waste wire clamping device K10 and the coil shaping device L10. The waste wire clamping device K10 takes out the waste coil wire cut off from the carrier D10. At the same time, the coil shaping device L10 squeezes and shapes the coil and PCB board to make the coil and PCB board accurately assembled in the housing.

[0246] Rotate the workstation plate A200 to transfer the shaped carrier D10 to the detection device M10. The detection device M10 performs non-contact detection to check whether the assembly status of the assembled RFID chip is qualified.

[0247] Rotate workstation tray A200 to transfer carrier D10 loaded with qualified RFID chips to palletizing device, transfer RFID chips to reading module for identification and recording, and after identification and recording, place RFID chips into material tray in sequence.

[0248] In summary, the 1000 RFID chip automatic assembly equipment can perform automated cyclic operations including PCB board punching and feeding, automatic shell shaping and feeding, coil winding, PCB board and coil welding, coil waste wire removal, coil assembly, waste wire clamping, coil shaping, finished product inspection, finished product identification and recording, and unloading.
