Description

Technical Field

[0001] The utility model relates to the technical field of silver bonding wire production, in particular to a winding machine for anti-jump wire silver bonding wire. Background Art

[0002] Wire bonding uses fine metal wires, utilizing heat, pressure, and ultrasonic energy to securely bond the wires to the substrate pads, achieving electrical interconnection between the chip and substrate, as well as information exchange between chips. Silver bonding wire is a significantly cheaper alternative to gold bonding wire. Silver alloy wire is primarily composed of single-crystal silver, typically containing 90%-99% silver. The remaining components are various trace elements. During the production and processing of silver bonding wire, the wire is coiled for transport before being released for processing in the next step.

[0003] During the winding process of existing silver bonding wires, they are usually tensioned to avoid wire jumping. However, the tensioning pressure is borne by a single silver bonding wire. The silver bonding wire itself is relatively thin and has a high silver content. As a result, the tensioning process can easily cause the silver bonding wire to stretch and become thinner or even break. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a winding machine for anti-jump wire bonding silver wire to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a winding machine for anti-jump wire bonding silver wire, comprising a base, a first motor and a winding wheel, a second motor is installed on one side of the base, and a bidirectional screw rod is connected to the output end of the second motor, guide rods are connected on both sides of the base, and a slide is connected between the guide rods and the bidirectional screw rod; a first bracket and a second bracket are respectively connected to the inside of the slide, and a tension spring is connected between the first bracket and the second bracket and the slide, a first roller is connected to the inside of the first bracket, and a second roller is connected to the inside of the second bracket.

[0006] By adopting the above technical solution, four sets of tension springs are used to apply tension to the two first brackets and the second bracket, so that the first roller and the second roller are closely attached to the wound silver wire to prevent the silver wire from spreading and causing wire jumping. At the same time, the contact area between the first roller and the second roller and the bonding silver wire is large, which prevents the silver wire from being stretched and broken due to large pressure. As the diameter of the winding wheel increases after the silver wire is wound, the first bracket and the second bracket will be forced to gradually move away from each other. However, when the tension is still applied by the tension spring, the first roller and the second roller are closely attached to the wound silver wire, and the first roller and the second roller are It can roll to reduce the wear between the first roller and the second roller, and the surfaces of the first roller and the second roller are wrapped with rubber sleeves to further reduce the pressure and prevent the bonding wire from stretching or breaking; after the second motor is started, the output end drives the bidirectional lead screw to rotate, and after the bidirectional lead screw rotates, it cooperates with the guide rod to guide and stop rotation, thereby displacing the slide, and then the two slides are away from the winding wheel, so as to facilitate the replacement of the winding wheel and the connection of the bonding wire to the winding wheel. After the replacement is completed, the output end of the motor drives the bidirectional lead screw to reverse, so that the two slides are close to the winding wheel, so that the first roller and the second roller are in contact with the bonding wire.

[0007] Furthermore, the slide is threadedly connected to the bidirectional lead screw, and the slide is slidingly connected to the base and the guide rod respectively.

[0008] By adopting the above technical solution, after the second motor is started, the output end drives the bidirectional screw to rotate. After the bidirectional screw rotates, it cooperates with the guide rod to guide and stop rotation, so that the slide moves so that the two slides are close to the winding wheel, so that the first roller and the second roller are in contact with the bonding silver wire, and then the second motor is automatically turned off.

[0009] Furthermore, there are two of each of the slide, the first bracket, the second bracket and the second roller, and the two first brackets and the two second brackets are mirror-imaged.

[0010] By adopting the above technical solution, by providing two second rollers and two groups of first rollers, the contact area between the bonding silver wires is increased, thereby preventing the silver wires from spreading and causing wire jumps.

[0011] Furthermore, six first rollers are provided, three in a group, and a total of two groups are provided, and eight tension springs are provided, two in a group, and a total of four groups are provided.

[0012] By adopting the above technical solution, tension is applied to the two first brackets and the second bracket through four sets of tension springs, and the first roller cooperates with the second roller to compress the entire circle of bonding silver wire.

[0013] Furthermore, the first bracket and the second bracket are both slidably connected to the slide, and the outer rings of the first roller and the second roller are both wrapped with rubber sleeves.

[0014] By adopting the above technical solution, as the diameter of the winding wheel increases after the silver wire is wound, the first bracket and the second bracket will be forced to gradually move away from each other, but when the tension is still applied by the tension spring, the first roller and the second roller are tightly attached to the wound silver wire, and the first roller and the second roller can roll to reduce the wear between them and the bonding silver wire. At the same time, the surfaces of the first roller and the second roller are wrapped with rubber sleeves to further reduce the pressure and prevent the bonding silver wire from stretching or breaking.

[0015] Furthermore, a first motor is installed on the top of the base, and a transmission rod is connected to the output end of the first motor. A sleeve is sleeved on the outside of the transmission rod, a transmission groove is opened in the middle of the back of the sleeve, a bolt passes through the top of the sleeve, and a socket is passed through the upper part of the outer surface of the base and the back, and a winding wheel is connected between the socket and the sleeve.

[0016] By adopting the above technical solution, the staff will clamp the winding wheel into the holder. Since the POM material has good elasticity and self-lubricating properties, the holder can open and wrap the winding wheel to prevent the winding wheel from falling off during the winding process and to prevent wear between the winding wheel and the base during rotation; then the staff will slide the sleeve toward the winding wheel so that the sleeve wraps one end of the winding wheel, and then the staff will tighten the bolt against the winding wheel. After the winding work is completed, the staff will loosen the bolt and slide the sleeve away from the winding wheel to separate the sleeve from the winding wheel. Then the staff will lift the winding wheel with force to remove it from the holder, thereby completing the work.

[0017] Furthermore, two bolts are provided, and the bolts are threadedly connected to the sleeve.

[0018] By adopting the above technical solution, the staff can tighten the bolts to prevent the winding wheel from transmitting torque and limiting the position, and the staff can loosen the bolts to facilitate the disassembly of the winding wheel.

[0019] Furthermore, the winding wheel is detachably connected to the holder, and the winding wheel is detachably connected to the sleeve via bolts.

[0020] By adopting the above technical solution, the staff loosens the bolt and slides the sleeve away from the winding wheel to separate the sleeve from the winding wheel. Then the staff lifts the winding wheel with force to remove it from the holder.

[0021] Furthermore, the card seat is made of POM material, and the cross section of the card seat is "U"-shaped.

[0022] By adopting the above technical solution, the staff will clamp the winding wheel into the holder. Since the POM material has good elasticity and self-lubrication, the holder can open and wrap the winding wheel, preventing the winding wheel from falling off during the winding process and avoiding wear between the winding wheel and the base during rotation.

[0023] Furthermore, the cross-sections of the transmission rod and the transmission groove are both plum blossom-shaped, and the sleeve is slidingly connected to the transmission rod through the transmission groove.

[0024] By adopting the above technical solution, the staff slides the sleeve toward the winding wheel so that the sleeve wraps around one end of the winding wheel, and then the staff tightens the bolt against the winding wheel.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The utility model is provided with a slide, a first bracket, a first roller, a second bracket, a second roller and a tension spring, and four sets of tension springs are used to apply tension to the two first brackets and the second bracket, so that the first roller and the second roller are closely attached to the wound silver wire to prevent the silver wire from spreading and causing wire jumping. At the same time, the contact area between the first roller and the second roller and the bonding silver wire is large, so that the silver wire is prevented from being stretched and broken by a large pressure. As the diameter of the winding wheel increases after the silver wire is wound, the first bracket and the second bracket will be forced to gradually move away from each other. However, when the tension is still applied by the tension spring, the first roller and the second roller are closely attached to the wound silver wire, and the first roller and the second roller can roll to reduce wear between them and the bonding silver wire. At the same time, the surfaces of the first roller and the second roller are wrapped with rubber sleeves to further reduce the pressure and prevent the bonding silver wire from being stretched or broken; the contact area is increased to reduce the pressure, so as to prevent the silver wire from being stretched or broken due to the pressure.

[0027] 2. The utility model is provided with a second motor, a bidirectional screw, a guide rod and a slide. After the second motor is started, the output end drives the bidirectional screw to rotate. After the bidirectional screw rotates, it cooperates with the guide rod to guide and stop rotation, thereby displacing the slide. After that, the two slides are away from the winding wheel, so as to facilitate the replacement of the winding wheel and the connection of the bonding silver wire to the winding wheel. After the replacement is completed, the output end of the motor drives the bidirectional screw to reverse, so that the two slides are close to the winding wheel, so that the first roller and the second roller are in contact with the bonding silver wire, thereby avoiding affecting the disassembly and assembly operation of the winding wheel.

[0034] The following describes an embodiment of the present invention based on its overall structure.

The outer rings of the first roller 14 and the second roller 16 are wrapped with rubber sleeves, and the surfaces of the first roller 14 and the second roller 16 are wrapped with rubber sleeves to further reduce the pressure and prevent the bonding silver wire from stretching or breaking.

[0038] Example 2:

[0039] On the basis of the above embodiment 1, in order to facilitate the disassembly and assembly of the winding wheel 3, the following settings are now adopted.

[0040] See Figure 1 、 Figure 2 and Figure 4 In the above embodiment, a first motor 2 is installed on the top of the base 1, and a transmission rod 5 is connected to the output end of the first motor 2. A sleeve 6 is sleeved on the outside of the transmission rod 5, and a transmission groove 7 is opened in the middle of the back of the sleeve 6. The cross-sections of the transmission rod 5 and the transmission groove 7 are both plum blossom-shaped. After the first motor 2 is started, the output end drives the transmission rod 5 to rotate, and the transmission rod 5 cooperates with the transmission groove 7 to transmit torque to rotate the sleeve 6; the sleeve 6 is slidably connected to the transmission rod 5 through the transmission groove 7, and a bolt 8 is passed through the top of the sleeve 6. There are two bolts 8, which are threadedly connected to the sleeve 6. The sleeve 6 is slid toward the direction of the winding reel 3 so that the sleeve 6 wraps one end of the winding reel 3. Then the staff tightens the bolt 8 against the winding reel 3; the outer surface of the base 1 There is a holder 4 running through the upper part and the back. The holder 4 is made of POM material, and the cross-section of the holder 4 is "U"-shaped. Since the POM material has good elasticity and self-lubrication, the holder 4 can be opened to wrap the winding wheel 3 to prevent the winding wheel 3 from falling off during the winding process and to prevent wear between the winding wheel 3 and the base 1 during the rotation of the winding wheel 3; the winding wheel 3 is connected between the holder 4 and the sleeve 6, and the winding wheel 3 is detachably connected to the holder 4. The winding wheel 3 is detachably connected to the sleeve 6 by a bolt 8. The staff loosens the bolt 8 and slides the sleeve 6 away from the winding wheel 3 to separate the sleeve 6 from the winding wheel 3. Then the staff lifts the winding wheel 3 with force to take it out of the holder 4.

[0041] The implementation principle of the present utility model is as follows: first, the staff inserts the winding wheel 3 into the card seat 4. Since the card seat 4 has good elasticity and self-lubrication due to the POM material, the card seat 4 can be opened to wrap the winding wheel 3, so as to prevent the winding wheel 3 from falling off during the winding process and to prevent wear between the winding wheel 3 and the base 1 during the rotation process; then the staff slides the sleeve 6 toward the winding wheel 3 so that the sleeve 6 wraps one end of the winding wheel 3, and then the staff tightens the bolt 8 to press against the winding wheel 3. After the winding wheel 3 is assembled, the staff connects the bonding silver wire to the winding wheel 3, and then the staff turns on the first motor 2 and the second motor 9;

[0042] After the second motor 9 is started, the output end drives the bidirectional screw 10 to rotate. After the bidirectional screw 10 rotates, it cooperates with the guide rod 11 to guide and stop the rotation, so that the slide 12 moves so that the two slides 12 are close to the winding wheel 3, so that the first roller 14 and the second roller 16 are in contact with the bonding silver wire, and then the second motor 9 is automatically turned off;

[0043] After the first motor 2 is started, the output end drives the transmission rod 5 to rotate, and the transmission rod 5 cooperates with the transmission slot 7 to transmit torque to rotate the sleeve 6. After the sleeve 6 rotates, the torque is transmitted through the bolt 8 to rotate the winding wheel 3. After the winding wheel 3 rotates, the bonding silver wire is wound. During this period, four sets of tension springs 17 are used to apply tension to the two first brackets 13 and the second bracket 15, so that the first roller 14 and the second roller 16 are close to the wound silver wire to prevent the silver wire from spreading and causing wire jumping. At the same time, the contact surface between the first roller 14 and the second roller 16 and the bonding silver wire The area is large, which prevents the silver wire from being stretched and broken due to a large pressure. As the diameter of the winding wheel 3 increases after the silver wire is wound, the first bracket 13 and the second bracket 15 are forced to gradually move away from each other. However, when the tension is still applied by the tension spring 17, the first roller 14 and the second roller 16 are in close contact with the wound silver wire, and the first roller 14 and the second roller 16 can roll to reduce the wear between them and the bonding silver wire. At the same time, the surfaces of the first roller 14 and the second roller 16 are wrapped with rubber sleeves to further reduce the pressure and prevent the bonding silver wire from being stretched or broken.

[0044] After the winding work is completed, the staff turns off the first motor 2 and turns on the second motor 9. After the second motor 9 is started, the output end drives the bidirectional screw 10 to rotate. After the bidirectional screw 10 rotates, it cooperates with the guide rod 11 to guide and stop rotation, thereby displacing the slide 12. After that, the two slides 12 are away from the winding wheel 3; at this time, the staff loosens the bolt 8 and slides the sleeve 6 away from the winding wheel 3 to separate the sleeve 6 from the winding wheel 3. Then the staff lifts the winding wheel 3 with force and takes it out of the holder 4, thereby completing the work.
