Description

Technical Field

[0001] This utility model belongs to the field of microelectronics technology, and specifically relates to a high-efficiency drying device for bonding wire processing. Background Technology

[0002] Ball bonding wire, also known as bonding wire, is a type of gold wire whose tip is burned into a small ball with a flame and then ball-bonded to the chip electrode. High-efficiency drying equipment for bonding wire processing is used to dry the wire during the process. However, traditional bonding wire drying equipment often results in inconsistent wire tension, messy wiring, and wire twisting and deformation during winding, affecting the quality of subsequent bonding processes. Furthermore, the fixed hot air outlet in traditional equipment leads to a single heating surface, causing uneven drying on both sides. Localized overheating can also cause oxidation or lattice distortion on the wire surface, directly affecting subsequent bonding strength and conductivity, making it difficult to improve product quality stability and process efficiency. To address the problems mentioned above, we propose a high-efficiency drying device for bonding wire processing. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency drying device for bonding wire processing, which has the advantages of uniform winding and uniform drying.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency drying device for bonding wire processing, comprising a drum, a rotating rod fixedly sleeved inside the drum, a side plate rotatably connected through the left side of the rotating rod, a limiting rod bolted to the front end of the opposite side of the two side plates, a limiting groove formed on the surface of the limiting rod, a limiting block slidably connected inside the limiting groove, a drum hinged to the front of the limiting block, and the surface of the limiting rod slidably sleeved through the inside of the drum, and a drying mechanism provided on the top of the side plate.

[0005] The above technical solution involves: a motor driving a rotating rod to rotate, which in turn drives a drum to rotate, which in turn winds the gold wire, which in turn drives the drum to rotate, and the drum to move a limiting block. A limiting groove restricts the movement of the limiting block, which moves along the path of the limiting groove. First, it moves to the right, causing the drum and gold wire to move to the right to wind. When it reaches the right end of the limiting groove, the path of the limiting groove changes the direction of the limiting block, causing it to drive the drum and gold wire to move to the left to wind the gold wire. This achieves constant tension automatic winding of the gold wire during the drying process. Its mechanical structure design effectively avoids the overlapping and uneven tension issues that occur during traditional winding, ensuring consistent winding density. It also reduces manual intervention, significantly improving production efficiency and product yield, and ensuring that each gold wire achieves a uniform drying effect and a smooth winding state.

[0006] The present invention is further configured such that the drying mechanism includes a bracket, the bracket is bolted to the rear end of the top of the side plate, a hot air blower is embedded in the left side of the side plate, an exhaust pipe is connected to the left side of the hot air blower, an exhaust pipe is connected to the right side of the hot air blower, and the top of the exhaust pipe is bolted to the top of the inner wall of the bracket, and an air outlet is provided at the bottom of the exhaust pipe.

[0007] The above technical solution involves a drying mechanism. A hot air blower draws air in through an exhaust duct, then through an outlet duct, and finally out through an outlet to dry the gold wire being wound at the bottom of the outlet. An array of uniformly spaced outlets is positioned at the top of the winding mechanism, enabling dynamic drying and winding processes to work in tandem. The hot air evenly covers the moving gold wire, effectively solving the problem of uneven drying caused by fixed positions in traditional equipment. The synchronous drying design avoids the waste of secondary heat treatment processes and prevents internal stress caused by sudden temperature changes during winding, ensuring consistent drying quality and significantly improving production continuity.

[0008] The present invention is further provided that a groove is formed in the middle of the surface of the rotating drum.

[0009] The above technical solution involves setting up a wire groove to facilitate the rotation of the rotating drum with the gold wire, preventing it from falling off.

[0010] The present invention is further configured such that gold wire is sleeved on the bottom of the inside of the wire groove and the surface of the drum.

[0011] The above technical solution allows for winding and drying by incorporating gold wire.

[0012] The present invention is further configured such that a motor is fixedly sleeved on the left side of the rotating rod.

[0013] The above technical solution involves incorporating a motor to drive the rotating rod.

[0014] The present invention is further configured such that a bearing is rotatably connected to the right side of the rotating rod.

[0015] The above technical solution, by incorporating bearings, can stabilize the rotating rod.

[0016] The present invention is further provided that a base is bolted to the bottom of the side plate.

[0017] The above technical solution uses a base to stabilize the device.

[0018] The present invention is further configured such that a frame is externally fitted onto the motor.

[0019] The above technical solution, by setting up a frame, can stabilize the motor.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model achieves constant tension automatic winding of gold wire during the drying process. Its mechanical structure design can effectively avoid the phenomena of wire stacking and uneven tension that occur during traditional winding, ensuring consistent winding density, reducing manual intervention, significantly improving production efficiency and product yield, and ensuring that each gold wire can obtain a uniform drying effect and a flat winding state.

[0022] 2. This utility model achieves dynamic drying and winding process coordination by setting an array of uniform air outlets at the top of the winding mechanism. Hot air evenly covers the moving gold wire, effectively solving the problem of uneven drying caused by the fixed position of traditional equipment. The synchronous drying design avoids the waste of secondary heat treatment process, and at the same time prevents the gold wire from generating internal stress due to sudden temperature changes during winding, ensuring the consistency of drying quality and significantly improving production continuity.

A side plate 3 is rotatably connected through the left side of the rotating rod 2. Limiting rods 4 are bolted to the front ends of opposite sides of the two side plates 3. Limiting grooves 5 are formed on the surface of the limiting rods 4. Limiting blocks 6 are slidably connected inside the limiting grooves 5. A rotating drum 7 is hinged to the front of the limiting block 6, and the surface of the limiting rod 4 passes through the interior of the rotating drum 7 and is slidably sleeved thereon. A drying mechanism is provided on the top of the side plates 3. A motor 15 drives the rotating rod 2 to rotate, which in turn drives the drum 1 to rotate. The gold wire 14 is wound up, which drives the rotating drum 7 to rotate. The rotation of the rotating drum 7 drives the limiting block 6 to move. The limiting groove 5 limits the movement of the limiting block 6. The limiting block 6 moves along the path of the limiting groove 5. First, it moves to the right, which drives the rotating drum 7 and the gold wire 14 to move to the right to wind up. When it moves to the right end of the limiting groove 5, the path of the limiting groove 5 changes the direction of the limiting block 6, which causes the limiting block 6 to drive the rotating drum 7 and the gold wire 14 to move to the left to wind up the gold wire 14. During the drying process, the gold wire 14 is automatically wound up with constant tension. Its mechanical structure design can effectively avoid the phenomena of overlapping wires and uneven tension that occur during traditional winding.

[0031] refer to Figure 1 , Figure 3 , Figure 4 A wire groove 13 is provided in the middle of the surface of the rotating drum 7. By setting the wire groove 13, the gold wire 14 can easily drive the rotating drum 7 to rotate and prevent it from falling off.

[0032] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 Gold wire 14 is sleeved on the bottom of the inside of the groove 13 and the surface of the drum 1. By setting the gold wire 14, it can be wound up and dried.

[0037] Brief description of the usage process: Attach the gold wire 14 to the drum, with its surface fitted inside the groove 13 on the surface of the rotating drum 7. The motor 15 drives the rotating rod 2 to rotate, which in turn drives the drum 1 to rotate. The rotation of the drum 1 causes the gold wire 14 to wind up, which in turn drives the rotating drum 7 to rotate. The rotation of the rotating drum 7 causes the limiting block 6 to move. The limiting groove 5 limits the movement of the limiting block 6. The limiting block 6 moves along the path of the limiting groove 5, first moving to the right, causing the rotating drum 7 and the gold wire 14 to move to the right to wind up. When it reaches the right end of the limiting groove 5, it stops. The path of groove 5 changes the direction of limit block 6, causing limit block 6 to drive the rotating drum 7 and gold wire 14 to move to the left to wind gold wire 14. During the drying process, the gold wire 14 is automatically wound with constant tension. Its mechanical structure design can effectively avoid the phenomena of wire stacking and uneven tension that occur during traditional winding, ensuring consistent winding density, reducing manual intervention, significantly improving production efficiency and product yield, and ensuring that each gold wire 14 can obtain a uniform drying effect and a flat winding state. After winding is completed, the rotating rod 2 is removed and the rotating drum 7 is taken out to store the gold wire 14.
