Description

Technical Field

[0001] This utility model relates to the field of metal ultra-fine wire production technology, and in particular to an automatic metal ultra-fine wire take-up and wire laying device. Background Technology

[0002] Extremely fine metal wires play a crucial role as bonding wires in semiconductor packaging and LED packaging. Here's a detailed explanation of their functions: 1) Current Conduction: One of the main functions of extremely fine metal wires as bonding wires is to connect pins to chips or silicon wafers, forming a current path. They ensure that electrical signals can be smoothly transmitted between the chip and external devices, thus guaranteeing the normal operation of the entire electronic device. 2) Heat Dissipation: Metal bonding wires, especially those made of metals with high thermal conductivity, can effectively dissipate heat, ensuring that the chip does not overheat during operation, thereby improving its performance and lifespan. 3) Process Flexibility: Although some metals are expensive, their stability allows for greater flexibility in wire bonding processes. At the same time, the fineness of the metal wires allows for more precise wiring during the packaging process to accommodate chips with higher integration levels.

[0003] Traditional automatic take-up and winding devices for ultra-fine metal wires have shortcomings in use. First, they cannot automatically change the wire roll after take-up is complete; second, they cannot achieve uniform wire routing during the take-up process. Therefore, it is necessary to optimize and improve traditional automatic take-up and winding devices for ultra-fine metal wires. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-6 As shown, this embodiment is an automatic take-up and winding device for ultra-fine metal wires, including a roll feeding assembly 1, a roll adsorption and rotation assembly 2, a bonding wire conveying assembly 3, a wiring assembly 4, and an adhesive strip bonding assembly 5. The roll feeding assembly 1 and the roll adsorption and rotation assembly 2 are arranged opposite to each other. The roll feeding assembly 1 is used to push rolls 6 one by one to the roll adsorption and rotation assembly 2. The roll adsorption and rotation assembly 2 is used to receive the rolls 6 and drive them to rotate and take up the wires. The bonding wire conveying assembly 3 is used to convey the bonding wires 7 to the rolls 6 in the take-up state. The wiring assembly 4 is used to drive the bonding wires 7 to reciprocate horizontally during the take-up process. The adhesive strip bonding assembly 5 is used to bond and fix the initial wire ends and broken wire ends of the bonding wires 7.

[0031] In this embodiment, the material roll 6 is composed of a take-up roller 601 and take-up baffles 602 located on both sides thereon. The take-up roller 601 and the take-up baffles 602 are provided with communicating inner holes, and the take-up baffles 602 are annular plates.

[0032] In this embodiment, the material roll feeding assembly 1 includes a material roll storage box 101, a feeding push rod 102, and a push plate 104. The material roll storage box 101 has a material roll storage chamber 103 inside, and the feeding push rod 102 is fixed on the outside of the material roll storage box 101. The movable end of the feeding push rod 102 is equipped with a push plate 104 that extends into the material roll storage chamber 103.

[0033] In this embodiment, the outer diameter of the material roll storage chamber 103 is matched with the outer diameter of the take-up baffle 602.

[0034] In this embodiment, the material roll storage box 101 is located at one end near the material roll adsorption and rotation assembly 2 as the material roll ejection port, and the other end of the material roll storage box 101 is provided with a through hole to facilitate the displacement of the movable rod in the feeding push rod 102.

[0035] In this embodiment, the material roll adsorption and rotation assembly 2 includes a first substrate 201, a take-up drive motor 202 and a vacuum suction cup 203. The take-up drive motor 202 is mounted on the first substrate 201, and the vacuum suction cup 203 for adsorbing and fixing the material roll 6 is mounted on the output end of the take-up drive motor 202.

[0036] In this embodiment, the shape of the vacuum suction cup 203 matches the shape of the take-up baffle 602. The distance between the vacuum suction cup 203 and the roll storage box 101 is 0.2 to 0.5 mm larger than the overall axial length of the roll 6. This way, when the roll 6 is pushed by the pusher plate 104 to a position close to the vacuum suction cup 203, the vacuum suction cup 203 can use suction to attract the roll 6 and completely detach it from the roll storage box 101. When the take-up drive motor 202 drives the roll 6 to rotate via the vacuum suction cup 203, it will not collide with the roll storage box 101.

[0037] In this embodiment, the bonding wire transport assembly 3 includes a second substrate 301, a tangent push rod 302, a cutting head 303, a pressure block 304, and guide rollers 305. The tangent push rod 302 is mounted on the second substrate 301, and the cutting head 303 is mounted on the movable end of the tangent push rod 302. The pressure block 304 is disposed opposite to the cutting head 303, and the area between the pressure block 304 and the cutting head 303 serves as the bonding wire transport area. The bonding wire 7 is linearly displaced along the bonding wire transport area under the guidance of multiple sets of guide rollers 305.

[0038] In this embodiment, the wiring assembly 4 includes a slide rail 401, a slider 402, a wiring support plate 403, and wiring wheels 404. The slide rail 401 is fixed to the outside of the roll storage box 101. The slider 402, which forms a linear guide pair with the slide rail 401, is installed on the slide rail 401. One end of the wiring support plate 403 is fixed to the outer wall of the slider 402, and two wiring wheels 404 are installed on the other end of the wiring support plate 403.

[0039] In this embodiment, the adhesive strip bonding assembly 5 includes a third substrate 501, an adhesive supply push rod 502, a mounting block 503, and adhesive strips 504. The adhesive supply push rod 502 is mounted on the third substrate 501. Several layers of adhesive strips 504 are mounted on the movable end of the adhesive supply push rod 502 via the mounting block 503. The two sides of the adhesive strips 504 are the adhesive surface and the release surface, respectively. The length of the adhesive strips 504 is equal to the length of the take-up roller portion 601 in the roll 6. To make it easier for the outermost adhesive strip 504 to detach, auxiliary separation components such as cutters and blowers can be added as needed.

[0040] A specific application of this embodiment is as follows: This device mainly consists of a roll feeding assembly 1, a roll adsorption and rotation assembly 2, a bonding wire conveying assembly 3, a wiring assembly 4, and an adhesive strip bonding assembly 5. The roll feeding assembly 1 pushes rolls 6 one by one to the roll adsorption and rotation assembly 2. The roll adsorption and rotation assembly 2 receives the rolls 6 and drives them to rotate and take in the wire. The bonding wire conveying assembly 3 conveys the bonding wires 7 to the rolls 6 in the take-in state. The wiring assembly 4 drives the bonding wires 7 to reciprocate horizontally during the take-in process. The adhesive strip bonding assembly 5 bonds and fixes the initial wire ends and broken wire ends of the bonding wires 7. In this way, the automatic roll replacement operation can be realized after the rolls 6 are taken in, and uniform wiring can be achieved during the take-in process of the rolls 6.
