Description

Technical Field

[0001] This utility model belongs to the field of electronic component processing equipment, specifically relating to a split carrier and RFID chip assembly equipment. Background Technology

[0002] RFID chips, or RFID tag chips, are a crucial component of RFID (Radio Frequency Identification) systems. The structure of an RFID chip includes a housing, a coil, and a PCB board housed within the housing. The coil and PCB board are connected by soldering. Therefore, RFID chip assembly typically involves first producing the coil using a winding machine, then manually soldering the PCB board, and finally manually placing the coil with the soldered PCB board into the housing to obtain the finished RFID chip. Due to the large production volume, numerous processes, and repetitive, error-prone manual operations, the error rate exceeds 20%, resulting in inconsistent product quality and severely impacting production efficiency and product quality.

[0003] Currently, there are automated assembly equipment for RFID chip assembly, but there is no suitable carrier for such automated RFID chip assembly equipment to accommodate the continuous work of assembling the various components in the RFID chip, which makes it impossible to meet production needs.

[0007] In some embodiments, when the second carrier is assembled onto the first carrier, the first carrier portion and the second carrier portion are disposed adjacent to each other.

[0008] In some embodiments, the second carrier has two end posts protruding from the second carrier at one edge near the through hole, and the through hole is located between the end posts and the second bearing portion.

[0013] In some embodiments, the first carrier includes a first carrier body and a second carrier body connected to the first carrier body. The first carrier body is provided with the first carrier portion, and the second carrier is detachably disposed on the first carrier body; the second carrier body is provided with a third carrier portion.

[0014] In some embodiments, the third bearing portion includes a first clamping member, a second clamping member, and a movable member; the first clamping member and the second clamping member enclose a clamping space; the first clamping member is disposed on the second bearing body, the second clamping member is disposed on the movable member, the movable member is movably disposed on the second bearing body, when the movable member is in a first position, the second clamping member is close to the first clamping member, and when the movable member is in a second position, the second clamping member is away from the first clamping member.

[0015] In some embodiments, the movable member is further provided with a positioning member on the side near the first support body; the first support body has a positioning hole corresponding to the position of the positioning member, and the second carrier has a positioning groove. When the movable member is in the first position, the positioning member passes through the positioning hole and is confined in the positioning groove. When the movable member is in the second position, the positioning member disengages from the positioning groove.

[0016] In some embodiments, the movable element is elastically disposed on the second support body, and the movable element is provided with a rotatable guide wheel.

[0032] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0033] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0034] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0035] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0036] It should be noted that the RFID chip includes a housing, coil, and PCB board. The split carrier D10 is suitable for the automated assembly process of RFID chip assembly. It can be used to carry the components in the RFID chip and transfer them to different workstations to adapt to the continuous work of assembling the various components in the RFID chip.

[0037] This utility model embodiment provides a split-type vehicle D10, such as Figures 1 to 5As shown, the split-type carrier D10 includes a first carrier D1 and a second carrier D2. The first carrier D1 has a first support portion D11, the top of which is a support position for the PCB board. The second carrier D2 has a second support portion D22 and a through hole D21. The second carrier D2 is detachably mounted on the first carrier D1. When the second carrier D2 is assembled on the first carrier D1, the first support portion D11 of the first carrier D1 passes through the through hole D21. The support position of the first support portion D11 can be exposed on the side of the second carrier D2 corresponding to the side where the second support portion D22 is located, or it can be hidden in the through hole D21 of the second carrier D2. The key is that when the PCB board is supported by the support position of the first support portion D11, it is either flush with or exposed to the surface of the second carrier D2. No particular restrictions are imposed here. Specifically, the top end of the first carrier D1 is provided with a first bearing portion D11, and the top end of the second carrier D2 is provided with a second bearing portion D22. The second carrier D2 has a through hole D21 extending from its bottom end to its top end. When the second carrier D2 is assembled on the first carrier D1, the first bearing portion D11 of the first carrier D1 passes through the through hole D21. The first bearing portion D11 of the first carrier D1 and the through hole D21 of the second carrier D2 cooperate and fix the second carrier D2 to position and fix it on the first carrier D1, and allow the workpiece carried by the first bearing portion D11 to be exposed on the second carrier D2. The first carrier D1 has a first carrier portion D11 for supporting a PCB board, and the second carrier D2 has a second carrier portion D22 for supporting a coil. The coil is wound on the second carrier portion D22. The second carrier D2 and the first carrier D1 are detachably coupled, allowing the second carrier D2 to be separated from the first carrier D1 for winding. Wires, such as copper wires, are wound on the second carrier portion D22 of the second carrier D2. The coil is then reassembled onto the first carrier D1, so that both the coil and the PCB board on the first carrier portion D11 are located on the surface of the second carrier portion D22 for soldering.

[0038] Specifically, the split-type carrier D10 can be set on the workbench of an RFID chip automatic assembly equipment. The workbench of this equipment is sequentially equipped with a PCB board loading station, a coil winding station, a soldering station, a wire cutting station, and a waste wire clamping station. When the split-type carrier D10 moves to the PCB board loading station, it loads the PCB board onto the first carrier D11. Then, the split-type carrier D10 moves to the coil winding station, where an external robotic arm picks up the second carrier D2, removes it from the first carrier D1, and moves it to the winding device for winding. During this process, the PCB board remains stably placed on the first carrier D1, unaffected by the movement of the second carrier D2. After the second carrier D2 is wound, the robotic arm places it back onto the first carrier D1. Because the second carrier D2 has a through hole D21, the first carrier D11 of the first carrier D1 passes through the through hole D21 and its end protrudes from the second carrier. D2 allows the second carrier D2 to be positioned on the first carrier D1, and the PCB board on the first support part D11 to be exposed on the second carrier D2. Therefore, the PCB board and the coil are placed side by side on the second carrier D2. The split carrier D10 is then transferred to the welding station. At this time, the welding device at the welding station can weld the PCB board and the coil on the split carrier D10, so that the two copper wires on the coil can be easily soldered to the PCB board. After welding, it is moved to the wire cutting station to cut off the excess copper wire on the split carrier D10, and then transferred to the waste wire clamping station to remove the cut waste copper wire on the split carrier D10.

[0039] Therefore, the split-type carrier D10, by providing a detachable second carrier D2 on the first carrier D1, allows for flexible use of either the first carrier D1 or the second carrier D2 as needed for PCB board loading, coil winding, and PCB board and coil soldering. When the PCB board is loaded onto the first bearing portion D11 of the first carrier D1, the second carrier D2 can detach from the first carrier D1 for winding. Since the first bearing 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 does not affect the placement of the PCB board on the first bearing portion D11. The first carrier D11 is positioned on the first carrier D1 during assembly, and the PCB board on the first carrier D11 is 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 PCB board and the coil can be directly soldered on the split carrier D10, and the subsequent waste wire cutting and removal can be performed. Thus, the split 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.

[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, when the second carrier D2 is assembled on the first carrier D1, the first carrier portion D11 and the second carrier portion D22 are arranged adjacent to each other, which facilitates the soldering operation of the PCB board and the coil. Furthermore, the second carrier portion D22 is located at the center of the second carrier D2, and the first carrier portion D11 is located near the edge of the second carrier D2, so that after the PCB board and the coil are soldered, it is convenient to cut off and remove excess soldered wires from the PCB board.

[0041] In some embodiments, such as Figure 1 As shown, two end posts D23 protruding from the second carrier D2 are provided on one side edge near the through hole D21. The end posts D23 extend vertically outward from the edge of the second carrier D2 where the second support portion D22 is located, and the surface of the end posts D23 is flush with the surface of the second carrier D2. The through hole D21 is located between the end posts D23 and the second support portion D22. Specifically, when the second carrier D2 detaches from the first carrier D1 and is transferred to an external winding device for winding, by providing these two end posts D23, the winding device winds one end post D23 of the second carrier D2, fixing the end of the coil to that end post D23. Then, the winding device winds the second support portion D22 of the second carrier D2 to form a coil. Finally, the winding device winds the other end post D23 of the second carrier D2, fixing the end of the coil to... On the end post D23, after the second carrier D2 is wound, when the second carrier D2 is placed back on the first carrier D1, the PCB board on the first carrier D11 can be exposed on the second carrier D2 and located exactly below the beginning and end of the coil, which facilitates the subsequent soldering operation of the PCB board and the beginning and end of the coil. In addition, the structure of the two end posts D23 can facilitate the movement to the wire cutting station to cut off the excess copper wire after the soldering is completed, and then to the waste wire clamping station to take out the cut waste copper wire.

[0042] In some embodiments, such as Figure 3 and Figure 4As shown, the second carrier D2 has a receiving groove D24, and the second supporting part D22 is elastically disposed in the receiving groove D24. The side wall of the second supporting part D22 is movably engaged with the groove wall of the receiving groove D24. Normally, the second supporting part D22 at least partially protrudes from the surface of the second carrier D2. Preferably, the gap between the second supporting part D22 and the receiving groove D24 needs to be sufficiently small and tightly fitted, i.e., the side wall of the second supporting part D22 and the groove wall of the receiving groove D24 are tightly and slidingly engaged to prevent the coil on the second supporting part D22 from getting stuck in the gap when disengaged. Specifically, the top of the second carrier D2 is recessed downwards to form the receiving groove D24, wherein the second supporting part D22 has a cylindrical structure, and the receiving groove D24 is adapted to have a circular groove structure. Understandably, when the second carrier D2 is used for winding, the coil is tightly wound and adhered to the peripheral wall of the second carrier portion D22 to prevent loosening during the winding process. This enhanced adhesion makes it difficult for the coil to be easily detached from the second carrier portion D22. Therefore, in this embodiment, by elastically setting the second carrier portion D22 on the second carrier D2, the portion of the second carrier portion D22 that protrudes from the surface of the second carrier D2 in its normal state is used for winding the coil. When it is necessary to remove the coil for the next operation, an external force can be applied to the second carrier portion D22 to move it downwards into the receiving groove D24. At this time, the coil can be detached from the second carrier portion D22 and transferred to the next processing station. After the external force is removed, the second carrier portion D22 can return to its normal state under elastic action.

[0043] Specifically, in this embodiment, a first elastic element D25 is provided inside the receiving groove D24, and the second supporting part D22 is connected to the second carrier D2 through the first elastic element D25. Specifically, the first elastic element D25 can be a spring or other component with elastic properties. The second supporting part D22 elastically abuts against the bottom of the receiving groove D24 through the first elastic element D25, allowing the second supporting part D22 to move up and down along the receiving groove D24 under the elastic action of the first elastic element D25, facilitating the release of the coil from the second supporting part D22.

[0044] In some embodiments, the first support portion D11 is a vertical rod, which can be a square rod, a cylindrical rod, etc., without particular limitation. Specifically, in this embodiment, the vertical rod is a square rod so that the top of the vertical rod can fit the PCB board. In addition, the top of the vertical rod may be provided with a groove to confine the PCB board to the top of the vertical rod.

[0045] In some embodiments, when the second support portion D22 is in its normal state, the portion exposed above 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 within 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.

[0046] In some embodiments, such as Figure 1 As shown, the first carrier D1 includes a first carrier body D12 and a second carrier body D13 connected to the first carrier body D12. The first carrier body D12 is provided with a first carrier portion D11, and the second carrier D2 is detachably disposed on the first carrier body D12. The second carrier body D13 is provided with a third carrier portion D14. The third carrier portion D14 is used to support the housing in the RFID chip, ensuring stable placement and precise positioning of the housing. Therefore, three carrier portions can be integrated in this split carrier D10 to respectively hold the PCB board, coil, and housing in the RFID chip. After the coil is soldered to the PCB board to form a shaped coil, it can be directly transferred to the third carrier portion D14 for precise alignment and assembly with the housing, thereby obtaining a shaped RFID chip. This achieves high efficiency, integration, and flexibility in the RFID chip assembly process.

[0047] In some embodiments, such as Figure 1As shown, the third bearing portion D14 includes a first clamping member D141, a second clamping member D142, and a moving member D143; the first clamping member D141 and the second clamping member D142 enclose a clamping space; the first clamping member D141 is disposed on the second bearing body D13, the second clamping member D142 is disposed on the moving member D143, and the moving member D143 is movably disposed on the second bearing body D13. When the moving member D143 is in a first position, the second clamping member D142 is close to the first clamping member D141, and the second clamping member D142 is in a clamping state relative to the first clamping member D141. When the moving member D143 is in a second position, the second clamping member D142 is away from the first clamping member D141, and the second clamping member D142 is in an open state relative to the first clamping member D141. The third support unit D14, through the cooperation of the first clamping member D141, the second clamping member D142, and the movably mounted moving member D143, achieves stable clamping and convenient release of the RFID chip housing. Specifically, the second clamping member D142 is disposed on the moving member D143, serving as the moving end of the clamping system. Driven by the moving member D143, it can achieve relative movement with the first clamping member D141. The moving member D143 is movably mounted on the first carrier D1 and can move freely within a certain range. The movement trajectory and position of the 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, such as... Figure 5 As shown, a guide A210 can be set on the worktable, forming an arc-shaped guide groove A211. A movable component D143 moves along this arc-shaped guide groove A211 to move the second clamping component D142 relative to the first clamping component D141. When the movable component D143 is in the first position, it drives the second clamping component D142 closer to the first clamping component D141 until the gap between them is small enough to clamp the housing. At this time, the second clamping component D142 is in a clamping state relative to the first clamping component D141, and the housing is securely fixed between them. When the moving part D143 is in the second position, it drives the second clamping part D142 away from the first clamping part D141 until the gap between the two is large enough to allow the housing to be released. At this time, the second clamping part D142 is in an open state relative to the first clamping part D141, and the housing can be easily taken out or put in. This enables fast and stable clamping and release of the housing, thereby greatly shortening the assembly cycle and reducing production costs.

[0048] In some embodiments, such as Figure 1 and Figure 2As shown, the movable component D143 is also provided with a positioning component D145 on the side near the first supporting body D12; the first supporting body D12 is provided with a positioning hole D121 corresponding to the position of the positioning component D145, and the second carrier D2 is provided with a positioning groove D29. When the movable component D143 is in the first position, the positioning component D145 passes through the positioning hole D121 and is limited to the positioning groove D29. When the movable component D143 is in the second position, the positioning component D145 disengages from the positioning groove D29. Specifically, through the positioning function of the positioning component D145, when the second carrier D2 is assembled on the first carrier body D12, the position of the moving component D143 is adjusted to the first 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 on the first carrier body D12. When it is necessary to detach the second carrier D2 from the first carrier body D12, the position of the moving component D143 is adjusted to the second position. At this time, the positioning component D145 is disengaged from the positioning groove D29, and the position of the second carrier D2 is in an active 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 moving member D143, when the moving member D143 moves to the first 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 supporting body D12. When the moving member D143 moves to the second 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.

[0049] Specifically, the second carrier D2 has an elongated positioning groove D29 on one side, and the movable component D143 has two positioning components D145, such as positioning pins, on the side near the second carrier D2. 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 bearing body D12.

[0050] In some embodiments, such as Figure 2 As shown, the movable component D143 is elastically mounted on the second supporting body D13, and the movable component D143 is provided with a rotatable guide wheel D16. The movement trajectory and position of the movable component D143 can be precisely controlled by a sophisticated mechanical structure or control system to ensure the accuracy and reliability of the position movement. For example, in this embodiment, such as... Figure 5As shown, guide members A210 can be installed at different workstations on the workbench. Guide members A210 form arc-shaped guide grooves A211. Guide wheels D16 move along these arc-shaped guide grooves A211 to move the movable member D143 relative to the second support body D13 to either the first or second position, eliminating the need for an additional power mechanism to drive the movement of the movable member D143. Furthermore, the arc-shaped guide grooves A211 of the guide members A210 provide a clear and stable movement path for the movable member D143. The guide wheels D16 can be rotatably connected to the movable member D143 via a rotating shaft. When the guide wheels D16 roll along the arc-shaped guide grooves A211, they ensure that the movable member D143 moves smoothly forward or backward at a predetermined angle and speed, thus ensuring that the movable member D143 can move accurately relative to the second support body D13. The rolling guide wheels D16 also allow for a rolling engagement with the guide members A210, significantly reducing friction and resistance during movement. Specifically, in this embodiment, the movable component D143 is elastically connected to the second bearing body D13 through a second elastic component D18, such as a spring. The elastic potential energy direction of the second elastic component D18 is consistent with the moving direction of the movable component D143, so that the movable component D143 can move relative to the second bearing body D13, while ensuring good restoring force and stability. When the guide wheel D16 moves out of the guide component A210 of the worktable, it can restore its original shape through its elastic force.

[0051] In some embodiments, such as Figure 1 As shown, the second supporting body D13 is provided with a guide device D17 along the moving direction of the moving member D143, and the 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 and the slide rail of the sliding pair structure, the movement trajectory of the moving member D143 is restricted, ensuring that it can only move along a predetermined linear direction. This effectively avoids unexpected movements such as deviation, swaying, or rotation of the moving member D143 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.

[0052] In some embodiments, the clamping cavity 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 one end open, and the second clamping member D142 is correspondingly disposed at the open end of the first clamping member D141.

[0053] In some embodiments, such as Figure 1As shown, 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. Understandably, 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.

[0054] Specifically, in this embodiment, the first carrier D1 is provided with at least two limiting members with an L-shaped cross-section. Each limiting member cooperates to form the 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 precise positioning and fixation of the second carrier D2 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; no particular limitation is made here.

[0055] In some embodiments, such as Figure 3 As shown, 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 to another location by an external robotic arm or clamp for winding operations, a gripping point needs to be formed at the top plate D26 to facilitate gripping by the robotic arm or clamp. 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 using a robotic arm clamp to grip the top plate D26, it is easier to bypass the connecting post D28 and directly act on the top plate D26, improving the ease of gripping.

[0056] 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 compared to the top plate D26 results in a larger mass and volume in the bottom structure, creating a bottom-heavy, top-light structure. This positions the center of gravity in the lower half of the second support D2, allowing for better distribution and bearing of loads from above or the sides, thereby effectively improving overall stability.

[0057] The second aspect of this utility model provides an RFID chip assembly device, including a rotating workstation and multiple split-type carriers D10 as described above. The first carrier D1 is fixedly mounted on the workstation. Guide members A210 are provided at different workstations on the workstation. Specifically, along the circumferential direction of the workstation, there are sequentially arranged PCB board loading positions, housing loading positions, winding positions, welding positions, cutting positions, coil assembly positions, waste wire clamping positions, detection positions, and unloading positions. By moving the split-type carriers D10 to different workstations via the workstation, PCB board loading, coil winding, welding, cutting, and waste wire removal can be performed, satisfying the continuous operation of assembling various components in the RFID chip. The above embodiments are not an exhaustive list based on this utility model; in addition, there may be several other embodiments not listed. Any substitutions and improvements made without departing from the concept of this utility model are within the protection scope of this utility model.
