Description

Technical Field

[0001] This invention relates to the field of semiconductor processing equipment technology, specifically to an automatic gold wire bonding machine. Background Technology

[0002] In semiconductor assembly and packaging processes, automated gold wire bonding machines are used to form electrical wire connections between ICs (integrated circuits) on silicon chips and their packaging substrates. During operation, the packaging substrate is typically placed on an operating table and positioned using a limiting mechanism. Then, a hydraulic cylinder drives the gold wire feeding system, precisely moving the bonding pins downwards. Simultaneously, the gold wire is precisely fed to the bonding pins, facilitating the gold wire bonding operation.

[0003] Currently, in the use of traditional automatic gold wire bonding machines, the limiting mechanism and the pushing mechanism are often designed as independent units, each relying on its own driving component. While this achieves the limiting and pushing functions of the substrate to a certain extent, it still has many drawbacks. First, because the limiting mechanism and the pushing mechanism each require independent driving components, the equipment cost increases significantly. Second, the design of independent driving components requires more control elements, sensors, and connecting wires, which not only increases the complexity of the equipment but also increases the difficulty of maintenance and troubleshooting. Once a driving component or related component fails, the operation of the entire equipment is easily affected, reducing the reliability and stability of the equipment. In addition, since each driving component requires energy to operate, the design of independent driving components leads to a significant increase in energy consumption. Summary of the Invention

The limiting mechanism includes a rotating shaft that is rotatably connected to the plate via a bearing. A displacement frame is movably connected to the outer side of the rotating shaft.

[0011] Preferably, a tensioning wheel is provided at the rear end of the inner side of the frame, and the bottom end of the tensioning wheel abuts against the top end of the transmission belt.

[0012] Preferably, a bevel gear set is connected between one of the rotating shafts and the linkage shaft, and a pulley set is provided at one end of the two rotating shafts near the bevel gear set.

[0013] Preferably, the inner side of the displacement frame is provided with a guide post, and the outer surface of the rotating shaft is provided with a guide groove that forms a sliding structure with the guide post. The guide groove is composed of a spiral groove and an annular grooves located at its two ends.

[0014] Preferably, each of the two plates is provided with a support spring at one end that is close to the other, and the support spring is symmetrical about the central axis of the plate.

[0015] Preferably, the adjustable wheel consists of a first conical wheel and a second conical wheel, and the first conical wheel and the second conical wheel are slidably connected.

[0016] Preferably, an adjustment mechanism is provided on one side inside the support frame. The adjustment mechanism includes a bidirectional lead screw that is rotatably connected to the frame via a bearing. A threaded plate sleeved on the outside of the support shaft is threaded onto the outer surface of the bidirectional lead screw. A handle is provided at the end of the bidirectional lead screw away from the frame.

[0017] Preferably, the threaded plate is symmetrically provided with limiting components at the ends of the first and second conical wheels, and the ends of the first and second conical wheels near the threaded plate are provided with limiting grooves that form a rotational structure with the limiting components.

[0018] Compared with the prior art, the beneficial effects of this invention are as follows: This invention, by incorporating a linkage mechanism, a pushing mechanism, and a limiting mechanism, achieves synchronous driving of both by the hydraulic cylinder. When the hydraulic cylinder drives the mounting plate to move vertically upwards, the gear meshes with the gear plate frame, driving the helical gear disc, adjustable wheel, and transmission wheel to automatically and intermittently rotate the conveyor belt, eliminating the need for manual intervention and ensuring a highly efficient and smooth bonding process. Simultaneously, the linkage mechanism drives the rotating shaft through a bevel gear set and a pulley set, enabling the rapid upward and downward movement of the limiting plate, automatically completing the limiting and releasing of the substrate, effectively preventing substrate displacement and improving bonding stability. Furthermore, the invention reduces the number of independent drive components and control elements, lowering equipment costs, energy consumption, and the difficulty of maintenance and troubleshooting. This simplifies the structure, improves equipment reliability and stability, and further enhances work efficiency. The invention also includes an adjustment mechanism connected to a bidirectional lead screw via a threaded plate. This allows for flexible adjustment of the diameter of the adjustable wheel, thereby adjusting the speed of the conveyor roller while keeping the adjustable wheel's speed constant. This enables precise control of the pushing distance, perfectly adapting to the pushing requirements of substrates of different sizes. This not only improves work efficiency but also significantly enhances the reliability and stability of the equipment.

[0019] 1. This invention incorporates a linkage mechanism and a pushing mechanism. Because the gear meshes with the gear plate frame, during the vertical upward movement of the mounting plate and gear plate frame driven by the hydraulic cylinder, the gear, linkage shaft, and helical gear disc one rotate. Because the helical gear disc two meshes with the helical gear disc one, the helical gear disc two and the adjustable wheel rotate together. Because the transmission wheel and the adjustable wheel are linked by a transmission belt, the transmission wheel and the conveyor roller rotate together, thereby operating the conveyor belt. This allows for the automatic, spaced pushing of bonded and unbonded substrates, achieving automatic loading and unloading, eliminating manual intervention, and ensuring smooth transitions in the bonding process.

[0020] 2. This invention incorporates a linkage mechanism and a limiting mechanism. Because the gear meshes with the gear plate frame, during the vertical upward movement of the mounting plate and gear plate frame driven by the hydraulic cylinder, the gear and linkage shaft rotate. Simultaneously, the rotating shaft rotates under the action of the bevel gear set and pulley set. Since the displacement frame and rotating column are slidably connected through guide columns and guide grooves, the displacement frame and limiting plate move vertically upward rapidly, automatically releasing the limiting on the substrate to prevent obstruction of substrate pushing. During the vertical downward movement of the gear plate frame, the limiting plate enables rapid automatic limiting of the substrate to prevent displacement during bonding, improving stability. Because each of the two mounting frames has a support spring at its closest point, the guide column can be pushed quickly into the guide groove, allowing the displacement frame to rotate rapidly.

[0021] 3. This invention incorporates an adjustment mechanism. Since the threaded plates are threadedly connected to the bidirectional lead screw, rotating the handle and the bidirectional lead screw allows the two threaded plates to move in opposite directions horizontally. Because both conical wheels one and two are rotatably connected to the threaded plates via limiting components and limiting grooves, and slidably connected to the support shaft, the horizontal reverse movement of conical wheels one and two allows for adjustment of the adjustable wheel diameter. This enables adjustment of the conveyor roller speed while keeping the adjustable wheel speed constant, thereby adjusting the pushing distance to accommodate the pushing operation of substrates of different sizes.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 , Figure 2 and Figure 9 This invention provides a technical solution: an automatic gold wire bonding machine, including a frame 1, a horizontal plate 2 at the front end of the frame 1, and a hydraulic cylinder 3 installed inside the horizontal plate 2. The bottom end of the hydraulic cylinder 3 is connected to a mounting plate 11. A displacement seat 10 is provided at the bottom end of the mounting plate 11. A gold wire feeding system 4 is installed at the bottom end of the displacement seat 10. A welding needle 12 is installed on the inner side of the bottom end of the gold wire feeding system 4. The gold wire feeding system 4 includes a frame, a wire feeding mechanism, a pneumatic device, a guide clamp, and a transducer corner. The top wall of the frame is connected to the bottom end of the displacement seat 10, and the bottom end of the frame is respectively provided with a guide clamp and a transducer corner. The transducer corner is connected to the welding needle 12. A pneumatic device is provided on the inner side of the frame. A wire feeding mechanism with gold wire wound around it is provided on the inner side of the frame above the pneumatic device. The guide clamp consists of a lower wire clamp and a wire guide.

[0034] See Figure 1 , Figure 2 and Figure 9It is understood that when the pneumatic device is activated, a downward vacuum force is applied to the gold wire. This vacuum force will automatically push the gold wire through the lower lead clamp, lead guide, and bonding pin 12 until the gold wire protrudes through the end of the bonding pin 12. During this process, the lower lead clamp is opened to release the gold wire, allowing the gold wire to be fed from the wire feeding mechanism toward the pneumatic device. After the substrate to be bonded is moved to below the bonding pin 12, the hydraulic cylinder 3 drives the bonding pin 12 to move down to the designated position. Then, the gold wire on the wire feeding mechanism is placed inside the pneumatic device, and the pneumatic device is used to force the gold wire to be fed to the bonding pin 12 through the clamping position and hole of the guide clamp, so that the deep cavity bonding operation can be performed through the bonding pin 12. This is existing technology, so it will not be described in detail here.

[0035] See Figures 1-3 and Figures 5-7 It can be seen that a support frame 13 is provided at the rear end of the frame 1, and a linkage mechanism 5 is provided on the inner side of the support frame 13. The linkage mechanism 5 includes a linkage shaft 503 that is rotatably connected between the frame 1 and the support frame 13 through a bearing. A gear 502 is sleeved on the outer side of the linkage shaft 503. A gear plate frame 501 connected to the mounting plate 11 is meshed on one side of the gear 502.

[0036] See Figures 1-3 and Figures 5-7 As can be seen, since gear 502 is meshed with gear plate frame 501, during the process of hydraulic cylinder 3 driving mounting plate 11 and gear plate frame 501 to move vertically upward or downward, gear 502, linkage shaft 503, helical gear disk 701 and bevel gear set 602 can rotate, thereby realizing the synchronous drive of hydraulic cylinder 3 on pushing mechanism 7 and limiting mechanism 6.

[0037] See Figure 1-Figure 5 and Figure 8It is known that a pushing mechanism 7 is provided on the inner side of the frame 1 and the support frame 13. The pushing mechanism 7 includes a conveyor roller 707 that is rotatably connected to the frame 1 via a bearing, and a conveyor belt 708 is wound around the outer side of the conveyor roller 707. A transmission wheel 706 is sleeved on the outer side of one of the conveyor rollers 707. A support shaft 703 is rotatably connected to the frame 1 and the support frame 13 on one side of the linkage shaft 503 via a bearing. A helical gear disk 702 and an adjustable wheel 704 are movably connected sequentially from back to front on the outer side of the support shaft 703. A transmission wheel 706 is wound around the outer side of the adjustable wheel 704 and the transmission wheel 706. The drive belt 705 and the helical gear disk 702 are meshed with a helical gear disk 701 sleeved on the outer surface of the linkage shaft 503. A disc 710 is provided on the outer side of the support shaft 703 at the rear end of the helical gear disk 702. A telescopic spring 709 is provided at one end of the disc 710 near the helical gear disk 702. L-shaped plates are symmetrically arranged on the outer surface of the support shaft 703. Straight grooves that form a sliding structure with the L-shaped plates are symmetrically opened on the inner surface of the helical gear disk 702. A tension wheel 9 is provided at the rear end of the inner side of the frame 1. The bottom end of the tension wheel 9 abuts against the top end of the drive belt 705.

[0038] See Figure 1-Figure 5 and Figure 8 As can be seen, since gear 502 is meshed with gear plate frame 501, during the process of hydraulic cylinder 3 driving mounting plate 11 and gear plate frame 501 to move vertically upward, gear 502, linkage shaft 503 and helical gear disk 1 701 can rotate. Since helical gear disk 2 702 is meshed with helical gear disk 1 701, helical gear disk 2 702 and adjustable wheel 704 rotate together. Since transmission wheel 706 and adjustable wheel 704 are linked through transmission belt 705, transmission wheel 706 and conveyor roller 707 rotate together, thereby making conveyor belt 708 run, so as to realize automatic interval pushing of bonded substrate and unbonded substrate through conveyor belt 708, so as to realize automatic loading and unloading, eliminate manual intervention, and ensure the smooth connection of bonding process.

[0039] See Figures 1-7 It can be seen that during the process of the hydraulic cylinder 3 driving the gold wire feeding system 4, welding needle 12 and toothed plate frame 501 to move down through the mounting plate 11, the meshing action of gear 502 and toothed plate frame 501 causes gear 502, linkage shaft 503 and helical toothed disc 701 to rotate in opposite directions together. Since helical toothed disc 702 and disc 710 are elastically connected through telescopic spring 709, helical toothed disc 702 makes reciprocating motion away from and towards helical toothed disc 701, thereby making the conveyor belt 708 stable and stationary.

[0040] See Figures 1-3 and Figures 5-7It is known that a plate 14 is connected to the rear end of the frame 1. A limiting mechanism 6 is installed through the inner side of the frame 1 above the conveyor belt 708. The limiting mechanism 6 includes a rotating shaft 601 that is rotatably connected to the plate 14 via a bearing. A displacement frame 605 is movably connected to the outer side of the rotating shaft 601. One end of the displacement frame 605 passes through the frame 1 and is connected to the limiting plate 606. A bevel gear set 602 is connected between the rotating shaft 601 and the linkage shaft 503. The bevel gear set 602 consists of a driving bevel gear connected to the linkage shaft 503. It consists of a driven bevel gear connected to the rotating shaft 601. A pulley group 608 is provided at one end of the two rotating shafts 601 near the bevel gear group 602. A guide post 604 is provided on the inner side of the displacement frame 605. A guide groove 603 is opened on the outer surface of the rotating shaft 601, which forms a sliding structure with the guide post 604. The guide groove 603 is composed of a spiral groove and an annular groove at both ends. A support spring 607 is provided at the end of the two plates 14 that are close to each other, and the support spring 607 is symmetrical about the central axis of the plate 14.

[0041] See Figure 2 , Figure 3 and Figures 5-7 As can be seen, since gear 502 is meshed with gear plate frame 501, during the process of hydraulic cylinder 3 driving mounting plate 11 and gear plate frame 501 to move vertically upward, gear 502 and linkage shaft 503 can rotate. At the same time, under the action of bevel gear set 602 and pulley set 608, rotating shaft 601 rotates. Since displacement frame 605 and rotating column are slidably connected through guide column 604 and guide groove 603, displacement frame 605 and limiting plate 606 can move vertically upward quickly, thereby automatically releasing the limiting of the substrate to prevent obstruction of the substrate's push. During the process of gear plate frame 501 moving vertically downward, the limiting plate 606 can quickly and automatically limit the substrate to prevent displacement during bonding and improve stability. Since the two mounting frames are provided with support springs 607 at their close ends, the guide column 604 can be pushed to move quickly into the guide groove 603, so that displacement frame 605 can rotate quickly.

[0042] See Figure 3 and Figures 5-7 As can be seen, since the guide groove 603 is composed of a spiral groove and annular grooves at both ends, when the displacement frame 605 moves to the designated position and the mounting plate 11 continues to move up or down, the guide post 604 can slide in the annular groove, so that the displacement frame 605 will not obstruct the continued movement of the mounting plate 11. Since the two mounting frames are provided with support springs 607 at their close ends, when the rotating shaft 601 changes from forward rotation to reverse rotation, the guide post 604 on the inner side of the displacement frame 605 can quickly move into the guide groove 603 under the action of the support springs 607, so that the displacement frame 605 can rotate quickly.

[0043] See Figure 7 It is known that the front end of the frame 1 is provided with a vertical frame, and the end of the limiting plate 606 away from the displacement frame 605 is provided with a sliding plate that forms a sliding structure with the vertical frame, which can guide and limit the limiting plate 606, so as to prevent the limiting plate 606 from shifting or tilting.

[0044] See Figure 1 , Figure 3 and Figure 8 It can be seen that the adjustable wheel 704 is composed of a first conical wheel 704a and a second conical wheel 704b, and the first conical wheel 704a and the second conical wheel 704b are slidably connected. An adjustment mechanism 8 is provided on one side inside the support frame 13. The adjustment mechanism 8 includes a bidirectional lead screw 801 that is rotatably connected to the frame 1 through a bearing. A threaded plate 802 sleeved on the outside of the support shaft 703 is threadedly connected to the outer surface of the bidirectional lead screw 801. A handle 805 is provided at the end of the bidirectional lead screw 801 away from the frame 1. Limiting elements 803 are symmetrically provided at the ends of the threaded plate 802 near the first conical wheel 704a and the second conical wheel 704b. Limiting grooves 804 that form a rotation structure with the limiting elements 803 are opened at the ends of the first conical wheel 704a and the second conical wheel 704b near the threaded plate 802.

[0045] See Figure 3 and Figure 8 As can be seen, since the threaded plate 802 is threadedly connected to the bidirectional lead screw 801, the two threaded plates 802 can be moved in opposite directions in the horizontal direction by rotating the handle 805 and the bidirectional lead screw 801. Since the first tapered wheel 704a and the second tapered wheel 704b are rotatably connected to the threaded plate 802 through the limiting member 803 and the limiting groove 804, and are slidably connected to the support shaft 703, the first tapered wheel 704a and the second tapered wheel 704b can be moved in opposite directions in the horizontal direction, thereby realizing the adjustment of the diameter of the adjustable wheel 704. This allows the speed of the conveying roller 707 to be adjusted while the speed of the adjustable wheel 704 remains constant, thereby realizing the adjustment of the pushing distance to adapt to the pushing operation of substrates of different sizes.

[0046] Working principle: When using this automatic gold wire bonding machine to bond substrates, the hydraulic cylinder 3 is activated, which drives the gold wire feeding system 4 and the welding pin 12 to move precisely downward through the mounting plate 11. The displacement seat 10 moves the welding pin 12 laterally in the front-back and left-right directions. At the same time, the pneumatic device is activated and applies a downward vacuum suction force to the gold wire. This vacuum suction force will automatically push the gold wire through the lower wire clamp, wire guide and welding pin 12 until the gold wire protrudes through the end of the welding pin 12, so that the gold wire bonding operation can be performed through the welding pin 12.

[0047] During the precise downward movement of the gold wire feeding system 4 and welding needle 12 driven by the hydraulic cylinder 3 through the mounting plate 11, the toothed plate frame 501 moves downward together. Through the meshing action of the gear 502 and the toothed plate frame 501, the gear 502, the support shaft 703 and the bevel gear set 602 rotate in opposite directions together. At the same time, under the action of the bevel gear set 602 and the pulley set 608, the two rotating shafts 601 rotate together. Through the sliding action between the displacement frame 605 and the rotating shaft 601, the displacement frame 605 drives the limiting plate 606 to move downward quickly and automatically limit the substrate to be bonded, so as to prevent it from shifting during the bonding process and improve stability.

[0048] After one bonding operation is completed, the hydraulic cylinder 3 drives the gold wire feeding system 4, welding pin 12, and gear plate frame 501 to move upward together via the mounting plate 11. During this process, gear 502, support shaft 703, helical gear disk 1 701, and bevel gear set 602 rotate forward together. Under the action of bevel gear set 602 and pulley set 608, the rotating shaft 601 rotates. Through the sliding action between the displacement frame 605 and the rotating column, the displacement frame 605 and the limiting plate 606 move vertically upward quickly, thereby automatically releasing the limiting of the substrate. At the same time, the helical gear disk 2 702 and helical gear disk 1 701 move upward together. The meshing action of 1 causes the helical gear disk 702 and the adjustable wheel 704 to rotate together. The transmission wheel 706 and the adjustable wheel 704 are linked by the transmission belt 705, causing the transmission wheel 706 and the conveyor roller 707 to rotate together, thereby making the conveyor belt 708 run. This allows for the automatic interval pushing of the bonded substrate and the unbonded substrate through the conveyor belt 708, so as to realize automatic loading and unloading. After that, the welding pin 12 can be moved down again so that the bonding operation can be performed again through the welding pin 12. The contents not described in detail in this description are the prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
