Description

Technical Field

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

[0002] Bonding wires are fine metal wires used in the assembly of semiconductor devices and integrated circuits to electrically connect the input / output bonding points of the chip's internal circuitry to the internal contact points of the lead frame. Currently, the main types include gold wire, alloy gold wire, copper wire, and palladium-plated copper wire. Silver has the lowest resistivity and the best conductivity among all metals, and its heat dissipation is better than that of gold. However, pure silver wire is unstable in forming balls and is easily oxidized, so its use still faces great challenges. In order to reduce packaging costs and meet the needs of LED bonding, bonding alloy silver wire has emerged.

[0003] In the existing technology, bonded silver wire needs to be wound up when used. However, the existing bonded silver wire is wound into rolls, which is not convenient to use and is not easy to disassemble from the winding machine. This makes it difficult for workers to operate the bonded silver wire and is inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing bonding silver wires are all wound into rolls, which is inconvenient to use and difficult to disassemble from the winding machine, resulting in troublesome operation and inconvenience for workers when handling bonding silver wires. Therefore, a bonding silver wire production material handling mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding mechanism for producing bonded silver wire includes a worktable and a take-up roller, and further includes: a chute formed on the top of the worktable, wherein a slider is slidably installed in the chute, a support plate is fixedly connected to the top of the slider, the take-up roller is mounted on the support plate, and a translation part for driving the slider to move laterally is provided on the worktable; and a locking block rotatably mounted on the support plate via a rotating shaft, wherein locking grooves matching the locking block are formed on both sides of the take-up roller.

[0007] In order to drive the support plate to move laterally to remove the card block from the slot, preferably, there are two sliders arranged symmetrically. The translation part includes a first motor fixedly connected to the side wall of the workbench. The output end of the first motor is fixedly connected to a bidirectional lead screw. The slider is threadedly connected to the bidirectional lead screw.

[0008] To improve movement stability, preferably, a limit rod is fixedly connected above the worktable, and the support plate is slidably connected to the limit rod.

[0009] In order to drive the take-up roller to rotate, preferably, a second motor is fixedly connected to the outer side of one of the support plates, and a rotating shaft is fixedly connected to the output end of the second motor. A turntable is fixedly connected to the rotating shaft, and the turntable is fixedly connected to the locking block through a connecting rod.

[0010] For easier access, preferably, a cylinder is fixedly connected to the top of the workbench, a support plate is fixedly connected to the telescopic end of the cylinder, a support rod is fixedly connected to the bottom of the support plate, and the support rod is slidably connected to the workbench.

[0011] To improve the tightness of the connection with the take-up roller, preferably, the locking block is threadedly connected to a threaded rod, and a first wedge block is mounted on the threaded rod via a bearing. The locking block has a sliding groove inside, and the first wedge block is slidably installed in the sliding groove. The locking block has a groove on its outer side, and a second wedge block is slidably installed inside the groove. The inclined surface of the second wedge block contacts the inclined surface of the first wedge block. A spring is installed between the second wedge block and the inner wall of the groove. The take-up roller has a connecting groove inside that matches the second wedge block.

[0012] Compared with the prior art, this utility model provides a material feeding mechanism for the production of bonded silver wire, which has the following beneficial effects:

[0013] 1. The connecting rod blank cutting and punching device drives two sliders to move away from each other along the slide groove through the translation part. The sliders drive two support plates to move away from each other. The support plates drive the locking block to disengage from the locking groove through the rotating shaft, so that the bonding silver wire wound on the winding roller can be removed. The operation is simple and convenient.

[0014] 2. The connecting rod blank cutting and punching device, through the start cylinder, drives the support plate to rise and support the take-up roller with bonding silver wire, preventing the take-up roller from falling when it is picked up. When installing the take-up roller, it can free up the hands and does not require manual support of the take-up roller, thus improving convenience. Attached Figure Description

[0022] Example:

[0023] Reference Figures 1-4 This utility model provides a feeding mechanism for producing bonded silver wire, including a workbench 1 and a winding roller 301 for winding bonded silver wire. It also includes a chute 201 located on the top of the workbench 1, where two sliders 202 are slidably mounted. A support plate 203 is fixedly connected to the top of each slider 202. The winding roller 301 is mounted on the support plate 203. A translation part for driving the sliders 202 to move laterally is provided on the workbench 1. A locking block 8 is rotatably mounted on the support plate 203 via a rotating shaft 302. Both sides of the winding roller 301 have slots 9 matching the locking block 8. Both the locking block 8 and the slots 9 are rectangular, allowing the locking block 8 to rotate synchronously with the winding roller 301.

[0024] During operation, the translation unit drives the two sliders 202 to move away from each other along the slide groove 201. The sliders 202 drive the two support plates 203 to move away from each other. The support plates 203 drive the locking block 8 to disengage from the locking groove 9 through the rotating shaft 302, so that the bonding silver wire wound on the winding roller 301 can be removed. The operation is simple and convenient.

[0025] The translation unit includes a first motor 204 fixedly connected to the side wall of the worktable 1. A bidirectional lead screw 205 is fixedly connected to the output end of the first motor 204. The bidirectional lead screw 205 is rotatably connected to the worktable 1 through bearings. The bidirectional lead screw 205 is located in the slide groove 201. The slider 202 is threadedly connected to the bidirectional lead screw 205. A horizontally set limit rod 206 is fixedly connected above the worktable 1. There are two limit rods 206, which are used to provide auxiliary support for the support plate 203 to improve the stability of the support plate 203 and the take-up roller 301. The support plate 203 is slidably connected to the limit rod 206. A second motor 303 is fixedly connected to the outer side of one of the support plates 203. A rotating shaft 302 is fixedly connected to the output end of the second motor 303. A turntable 7 is fixedly connected to the rotating shaft 302. The turntable 7 is fixedly connected to the locking block 8 through a connecting rod. There is a certain space between the turntable 7 and the locking block 8.

[0026] During operation, the second motor 303 is started, and its output end drives the shaft 302 connected to it to rotate. The shaft 302 drives the turntable 7 to rotate, the turntable 7 drives the locking block 8 to rotate, and the locking block 8 drives the take-up roller 301 to rotate to take up the bonding silver wire. After the take-up is completed, the first motor 204 is started, and its output end drives the bidirectional lead screw 205 to rotate. The bidirectional lead screw 205 drives the two sliders 202 to move away from each other along the slide groove 201. The sliders 202 drive the two support plates 203 to move away from each other, thereby driving the locking block 8 to disengage from the slot 9, making it easy to disassemble the take-up roller 301.

[0027] A cylinder 4 is fixedly connected to the top of the workbench 1. The cylinder 4 is vertically positioned, and a support plate 5 is fixedly connected to the telescopic end of the cylinder 4. The top of the support plate 5 is arc-shaped to accommodate the limitations of the take-up roller 301 and increase the contact area. A vertically positioned support rod 6 is fixedly connected to the bottom of the support plate 5. The support rod 6 is slidably connected to the workbench 1 and is used to support the support plate 5 to improve the stability of the support plate 5 in lifting the take-up roller 301. A threaded rod 10 is threadedly connected to the locking block 8. The threaded rod 10 is horizontally positioned, and a first wedge block 11 is mounted on the threaded rod 10 via a bearing. The first wedge block 11 has two inclined surfaces. The inside of the locking block 8 is provided with a sliding groove 12. The first wedge block 11 is slidably installed in the sliding groove 12. The outside of the locking block 8 is provided with a groove 13. The second wedge block 14 is slidably installed inside the groove 13. The inclined surface of the second wedge block 14 is in contact with the inclined surface of the first wedge block 11. In the initial state, the second wedge block 14 is completely in the groove 13. A spring 15 is installed between the second wedge block 14 and the inner wall of the groove 13. The inside of the take-up roller 301 is provided with a connecting groove 16 that matches the second wedge block 14.

[0028] During operation, the cylinder 4 is activated, and its telescopic end drives the support plate 5 to rise and support the take-up roller 301 with bonded silver wires, preventing the take-up roller 301 from falling when it is picked up. When installing the take-up roller 301, hands can be freed up, and there is no need to manually support the take-up roller 301 for installation, which improves convenience. By rotating the threaded rod 10, the threaded rod 10 drives the first wedge block 11 to slide in the sliding groove 12. The first wedge block 11 drives the second wedge block 14 to slide out of the locking block 8 and compress the spring 15, moving the second wedge block 14 into the connecting groove 16, so that the connection with the take-up roller 301 is tighter. By reversing the threaded rod 10, the spring 15 is reset, so that the second wedge block 14 is moved out of the connecting groove 16.

[0029] In use, the bonding silver wire production material handling mechanism works by starting the cylinder 4, which causes the extension end to lift the support plate 5 to hold the take-up roller 301 containing the bonding silver wire, preventing it from falling off when being taken out. Then, the first motor 204 is started, and its output end drives the bidirectional lead screw 205 to rotate. The bidirectional lead screw 205 drives the two sliders 202 to move away from each other along the slide groove 201. The sliders 202 drive the two support plates 203 to move away from each other, thereby causing the locking block 8 to disengage from the locking groove 9, so that the bonding silver wire wound on the take-up roller 301 can be removed. The operation is simple and convenient.

[0030] By rotating the threaded rod 10, the threaded rod 10 drives the first wedge block 11 to slide in the sliding groove 12. The first wedge block 11 drives the second wedge block 14 to slide outward of the locking block 8 and compress the spring 15, moving the second wedge block 14 into the connecting groove 16, so that it is more tightly connected with the take-up roller 301. By reversing the threaded rod 10, the spring 15 is reset, so that the second wedge block 14 is moved out of the connecting groove 16.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
