Description

Technical Field

[0001] This utility model belongs to the field of bonding silver wire technology, and in particular relates to a winding device for the production of bonding silver wire. Background Technology

[0002] With the increasing density, speed, and miniaturization of electronic packaging, gold bonding wires can no longer meet the requirements due to cost and performance issues. Copper and silver bonding wires, which are more cost-effective, are gradually becoming alternatives to gold wires. However, copper bonding wires have problems such as high hardness, easy oxidation, and complex manufacturing processes.

[0003] Silver is inexpensive and has excellent electrical and thermal conductivity when used as a bonding wire, making it one of the most promising materials for the future development of high integration, high density, and high speed in electronic packaging.

[0004] During production, the bonded silver wire is wound up using a winding device.

[0005] However, existing technologies have some problems: when using existing winding devices, the bonding silver wires are prone to become disordered during the winding process, making it impossible for the winding device to keep them neat. Therefore, we propose a winding device for the production of bonding silver wires. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a winding device for producing bonded silver wire, which uses an auxiliary mechanism to position and wind the bonded silver wire, thereby maintaining the neatness of the bonded silver wire during winding.

[0007] This utility model is implemented as follows: a winding device for producing bonding silver wire includes an auxiliary mechanism; the auxiliary mechanism includes a column fixed on a positioning base plate, a movable ring sleeved on the column, positioning cylinders fixed on both sides of the movable ring, a first movable rod and a second movable rod movably connected inside the positioning cylinders on both sides, a pressing wheel mounted on the end of the first movable rod through a wheel frame, a push block fixedly connected to the end of the second movable rod, and a bonding knife fixedly provided at the bottom of the push block.

[0008] Specifically, limit rings are welded onto the first moving rod and the second moving rod respectively, and a spring is connected between the limit ring and the positioning cylinder. The spring is respectively sleeved on the first moving rod and the second moving rod.

[0010] Specifically, an extension rod is fixedly provided on one side of the push block, and a connecting plate is fixedly provided on one side of the extension rod. The connecting plate is movably connected to two support wheels through a first rotating component.

[0011] Specifically, it also includes a positioning base plate, on which a rotating plate is provided, and on which a winding mechanism is provided, the winding mechanism including a winding rod fixedly mounted on the rotating plate, and the winding rod having embedded grooves on both sides.

[0012] Specifically, a servo motor is fixedly installed on the lower part of the positioning base plate, and the output shaft of the servo motor passes through the positioning base plate and is movably connected to the rotating plate.

[0013] Specifically, a positioning ring is fixedly provided at the upper end of the rotating plate in the middle of the winding rod. A lead screw is movably connected inside the positioning ring. A threaded ring is threaded to the upper end of the lead screw. Crank rods are respectively connected to both sides of the positioning ring and the threaded ring. A push plate is movably connected between the upper and lower crank rods. An arc-shaped plate is fixedly provided on the outer side of the push plate.

[0014] Specifically, the crank rod, the push plate, and the arc plate are movably positioned within the embedded groove, and a nut is fixedly connected to the upper end of the lead screw, with a second rotating component fixedly connected to the upper end of the nut.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In use, this utility model uses an auxiliary mechanism to restrict the winding of the bonding silver wire, so that the bonding silver wire can be neatly wound on the take-up drum.

[0017] Furthermore, a push block is connected to the auxiliary mechanism via a second moving rod, and a bonding knife is provided at the lower part of the push block. The bonding knife enables the bonding silver wires to be bonded together sequentially, preventing the bonding silver wires from tangling together during the winding process.

[0018] In the auxiliary mechanism, a pressing wheel is connected via a first moving rod. The bonding silver wires are sequentially bonded by the action of the push block and the bonding knife, and the pressing wheel applies negative pressure to the bonding silver wires to maintain the tightness of the winding of the bonding silver wires.

[0027] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] like Figures 1 to 5 As shown in the figure, the present invention provides a winding device for producing bonding silver wire, including an auxiliary mechanism 5. The auxiliary mechanism 5 includes a column 501 fixed on a positioning base plate 1. A movable ring 507 is sleeved on the column 501. Positioning cylinders 502 are fixed on both sides of the movable ring 507. A first movable rod 503 and a second movable rod 504 are movably connected inside the positioning cylinders 502. A pressing wheel 511 is installed at the end of the first movable rod 503 through a wheel frame 510. A push block 512 is fixedly connected at the end of the second movable rod 504. A bonding knife 513 is fixedly provided at the bottom of the push block 512.

[0029] In this embodiment, preferably, a limiting ring 505 is welded to the first moving rod 503 and the second moving rod 504 respectively, and a spring 506 is connected between the limiting ring 505 and the positioning cylinder 502. The spring 506 is respectively sleeved on the first moving rod 503 and the second moving rod 504.

[0030] It should be noted that the setting of the limiting ring 505 and the spring 506 facilitates adaptive adjustment according to the winding size when winding the bonding silver wire.

[0031] In this embodiment, preferably, sliding grooves 508 are respectively provided on both sides of the column 501, and sliding blocks 509 are fixed on both sides of the inner wall of the moving ring 507, with the sliding blocks 509 movably located inside the sliding grooves 508.

[0032] It should be noted that the sliding groove 508 and the sliding block 509 are designed to maintain the stability of the moving ring 507 and prevent it from rotating while restricting the delivery of the bonding silver wire.

[0033] In this embodiment, preferably, an extension rod 514 is fixedly provided on one side of the push block 512, and a connecting plate 515 is fixedly provided on one side of the extension rod 514. The connecting plate 515 is movably connected to two support wheels 516 through the first rotating member 517.

[0034] It should be noted that the support rollers 516 are installed via the extension rod 514, and the two support rollers 516 are rotated and adjusted via the first rotating component 517, so that the angle of the two support rollers 516 can be adjusted, which facilitates the stable delivery of the bonding silver wire.

[0035] In this embodiment, preferably, it also includes a positioning base plate 1, a rotating plate 2 is provided on the positioning base plate 1, a winding mechanism 4 is provided on the rotating plate 2, and the winding mechanism 4 includes a winding rod 401 fixedly disposed on the rotating plate 2, with embedded grooves 402 on both sides of the winding rod 401.

[0036] It should be noted that the positioning base plate 1 facilitates the installation of the auxiliary mechanism 5 and the winding mechanism 4, and the winding rod 401 rotates with the rotating plate 2, which facilitates the rotation of the winding drum and the winding of the bonding silver wire.

[0037] In this embodiment, preferably, a servo motor 3 is fixedly installed on the lower part of the positioning base plate 1, and the output shaft of the servo motor 3 passes through the positioning base plate 1 and is movably connected to the rotating plate 2.

[0038] It should be noted that the servo motor 3 drives the rotating plate 2 to rotate, which in turn drives the winding rod 401 and the winding drum to wind the bonding silver wire.

[0039] In this embodiment, preferably, a positioning ring 404 is fixedly provided at the upper end of the rotating plate 2 in the middle of the winding rod 401. A lead screw 403 is movably connected inside the positioning ring 404. A threaded ring 405 is threadedly connected to the upper end of the lead screw 403. Crank rods 406 are respectively connected to both sides of the positioning ring 404 and the threaded ring 405. A push plate 407 is movably connected between the upper and lower crank rods 406. An arc-shaped plate 408 is fixedly provided on the outer side of the push plate 407.

[0040] It should be noted that the positioning ring 404 and the threaded ring 405 facilitate the connection between the crank rod 406 and the push plate 407. By rotating the lead screw 403, the position of the threaded ring 405 can be adjusted, so that the crank rod 406, the push plate 407 and the arc plate 408 can be unfolded, which facilitates the fixing of the winding drum.

[0041] In this embodiment, preferably, the crank 406, push plate 407 and arc plate 408 are movably located in the embedded groove 402, and the upper end of the lead screw 403 is fixedly connected to the nut 409, and the upper end of the nut 409 is fixedly connected to the second rotating member 410.

[0042] It should be noted that the second rotating component 410 and the nut 409 enable the lead screw 403 to be rotated and adjusted, which facilitates the unfolding and retraction of the crank 406, push plate 407 and arc plate 408, and makes it easier to place and remove the winding drum.

[0043] The specific operational steps for this application are as follows:

[0044] In use, the lead screw 403 is rotated by the second rotating component 410 and the nut 409, which facilitates the upward movement of the threaded ring 405, and the retraction of the crank 406, push plate 407 and arc plate 408 into the embedded groove 402, so that the take-up drum can be placed on the take-up rod 401. Then, the lead screw 403 is rotated again by the second rotating component 410 and the nut 409, which facilitates the downward movement of the threaded ring 405, and the retraction of the crank 406, push plate 407 and arc plate 408, so as to fix the take-up drum. Then, the servo motor 3 drives the rotating plate 2 to rotate, so as to wind the bonding silver wire.

[0045] Furthermore, during the winding of the bonding silver wire, the push block 512 adheres to the take-up drum, and the bonding knife 513 adheres to one side of the bonding silver wire already wound on the take-up drum, so that the bonding silver wire being wound can adhere tightly to one side of the bonding silver wire already wound on the take-up drum, maintaining the tightness of the bonding silver wire winding. During the winding of the bonding silver wire, the pressing wheel 511 can adhere to the already wound bonding silver wire, so that the bonding silver wire can maintain the tightness of the winding and prevent it from unraveling.

[0046] An extension rod 514 is provided on one side of the push block 512, and two support wheels 516 are installed at the end via a first rotating member 517. The bonding silver wire is passed between the two support wheels 516, and the angle of the two support wheels 516 is adjusted by rotating the first rotating member 517 to maintain the stable delivery of the bonding silver wire.

[0047] As the bonding silver wire is wound, the size of the bonding silver wire on the take-up drum gradually increases. At this time, the structure in the auxiliary mechanism 5 is adaptively adjusted by the springs 506 on the first moving rod 503 and the second moving rod 504 to accommodate the gradually increasing size of the bonding silver wire on the take-up drum.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
