Description

Technical Field

[0001] This invention relates to the field of semiconductor welding technology, specifically to a multi-axis linkage intelligent wire bonding device and its welding method. Background Technology

[0002] With the rapid iteration of semiconductor packaging and microelectronics manufacturing technologies, high-end electronic devices are gradually developing towards miniaturization, high precision, and high-density integration. As the core key process for interconnecting the pins of semiconductor chips and precision components, wire bonding technology has increasingly stringent requirements for the processing accuracy, operational stability, and temperature control capabilities of equipment. Multi-axis linkage intelligent wire bonding equipment is also widely used in precision semiconductor wire bonding processing and production.

[0003] Currently, traditional intelligent wire bonding equipment has obvious technical defects. During long-term continuous operation, the internal components of the control box and the external wire bonding assembly will continuously generate residual heat. Existing equipment lacks a reasonable heat dissipation structure, and heat is easily accumulated and retained inside the control box. The residual heat of the wire bonding assembly cannot be dissipated in time. Long-term accumulation of residual heat can easily lead to overheating and performance degradation of components, which in turn can cause abnormal equipment operation and frequent failures, affecting the stability and service life of the equipment and making it difficult to meet the working conditions of long-term continuous precision wire bonding operations.

[0018] 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.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1: An embodiment of the present invention provides a multi-axis linkage intelligent wire bonding device, such as... Figures 1-10 As shown, the system includes a control box 1, which is equipped with an X-axis assembly, a Y-axis assembly, and a Z-axis assembly. The X-axis assembly controls the movement of the Y-axis assembly, and the Y-axis assembly controls the movement of the Z-axis assembly. The Z-axis assembly includes a moving block 4, on which a wire bonding mechanism is mounted. The control box 1 is also equipped with a wire bonding table. A cooling assembly is installed inside the control box 1. The cooling assembly includes a rotating tube 14, which extends upward out of the control box 1. A corrugated hose 13 is connected through the upper end of the rotating tube 14, and the output end of the corrugated hose 13 faces the wire bonding assembly.

[0022] The corrugated hose 13 is connected to the jet nozzle 17 at its output end, and a drive rod 12 is fixedly installed on the moving block 4. The other end of the drive rod 12 is connected to the corrugated hose 13.

[0023] The working principle and beneficial effects of the above technical solution are as follows: The X-axis assembly, Y-axis assembly and Z-axis assembly are controlled by the control box 1 to achieve three-axis linkage, which drives the moving block 4 and the wire bonding mechanism to complete multi-directional precise displacement, so that the wire bonding mechanism can quickly align to the workpiece welding position; During the continuous operation of the equipment, the internal components of the control box 1 and the wire bonding assembly continuously generate residual heat. The internal cooling assembly of the control box 1 operates synchronously, relying on the rotating tube 14 and the corrugated hose 13 to form a conductive heat dissipation path. The flexible adjustment of the corrugated hose 13 directs the heat dissipation medium to the wire bonding assembly. At the same time, the cooling assembly provides concentrated heat dissipation to the inside of the control box 1, realizing synchronous heat dissipation and cooling of the internal components and the external wire bonding assembly.

[0024] The integrated cooling system in the control box 1, with the help of the rotating tube 14 and the corrugated hose 13, can simultaneously dissipate heat from the internal components and external wire bonding components of the control box 1. This effectively avoids the problem of internal heat accumulation and component overheating and aging during long-term continuous operation, and eliminates abnormal operation and frequent failures caused by high temperature heat accumulation. This significantly improves the stability and continuous operation capability of the equipment and extends the overall service life of the equipment.

[0025] Example 2: Based on Example 1 above, as follows Figure 1 As shown, the X-axis assembly includes two symmetrical fixed boxes 2, which are fixedly mounted on the upper surface of the control box 1. The fixed boxes 2 have a moving groove, and a driving component 1 is installed inside the fixed boxes 2. The Y-axis assembly includes two symmetrical fixed plates 6, which extend through the moving groove into the fixed boxes 2. The driving component 1 is used to drive the fixed plates 6 to move. The upper ends of the two fixed plates 6 are fixedly connected to the moving box 3. The lower surface of the moving box 3 is provided with a sliding groove, and a moving block 4 is slidably mounted in the sliding groove. A driving component 2 is installed inside the moving box 3.

[0026] Among them, the first driving component and the second driving component can adopt a screw and nut transmission or an electric slide rail drive structure, which are all existing technologies and can be selected by those skilled in the art.

[0027] The working principle and beneficial effects of the above technical solution are as follows: the control box 1 controls the operation of the drive component 1 inside the fixed box 2, which drives the fixed plate 6 to move laterally along the moving groove of the fixed box 2 in the X-axis direction, thereby driving the moving box 3 to complete the X-axis displacement adjustment as a whole; the drive component 2 inside the moving box 3 can drive the moving block 4 to slide along the bottom slide groove of the moving box 3 in the Y-axis direction; through the sequential linkage of the X-axis and Y-axis, the Z-axis assembly and the wire bonding mechanism are driven to complete multi-directional precise alignment; the overall structure operates smoothly, the movements do not interfere with each other, the equipment adjustment is more flexible, and the practicality is stronger.

[0028] Example 3: Based on Examples 1-2 above, as follows Figures 1-4 As shown, the Z-axis assembly also includes a partition plate 16, which is fixedly mounted on the lower end of the moving block 4. An electric push rod 9 is fixedly mounted on the left side of the partition plate 16, and a push rod is fixedly mounted on the lower output end of the electric push rod 9. A clamping block 11 is fixedly mounted on the lower end of the push rod. A mating box 10 is also fixedly mounted on the left side of the partition plate 16. The push rod slides through the mating box 10, and a point control plate 20 is fixedly mounted on the push rod. A point control button 21 is fixedly mounted on the inner wall of one side of the mating box 10. The point control plate 20 and the point control button 21 cooperate with each other.

[0029] Preferably, the wire bonding mechanism includes an electric push rod 15, which is fixedly mounted on the right side of the dividing plate 16. An ultrasonic transducer 18 is fixedly mounted on the lower output end of the electric push rod 15, and a chopping knife 19 is mounted on the lower side of the ultrasonic transducer 18. The wire bonding table includes a wire bonding box 7 and a wire bonding plate 5. The wire bonding box 7 is mounted on the upper surface of the control box 1, and the wire bonding plate 5 is mounted on the wire bonding box 7. Several vacuum suction cups are provided inside the wire bonding box 7, and several suction holes are opened on the wire bonding plate 5, through which the vacuum suction cups pass.

[0030] The working principle and beneficial effects of the above technical solution are as follows: After the X-axis assembly and Y-axis assembly are moved into place, the moving block 4 will drive the sub-plate 16 to move above the welding station. The welding plate 5 uses the vacuum suction cup inside the welding box 7 in conjunction with the suction hole to perform negative pressure suction and fixation on the workpiece, ensuring that the workpiece does not shift during the welding process. Before welding, electric push rod 19 drives the push rod to move down, which drives the clamping block 11 to clamp the workpiece to be welded, realizing secondary positioning and clamping; after clamping, electric push rod 2 15 on the right side of the split plate 16 drives the ultrasonic transducer 18 and the cutting blade 19 to move down, and uses ultrasonic vibration to complete the precision wire welding operation. During the operation of the equipment, the cooling component continuously dissipates heat to the inside of the control box 1 and the wire welding component. The dual positioning method of vacuum suction cup adsorption combined with mechanical clamping by clamping block 11 greatly improves the firmness of workpiece fixation, effectively avoids workpiece displacement caused by welding vibration, and ensures welding accuracy; the compact structure can move synchronously with multi-axis components, further improving the welding stability of the equipment.

[0031] Example 4: Based on Example 3 above, as follows Figures 5-6 As shown, the control box 1 is equipped with an isolation plate 35, and an installation groove is provided in the center of the isolation plate 35. A placement box 22 is fixedly installed in the installation groove. An ultrasonic generator is provided in the placement box 22 and is electrically connected to the ultrasonic transducer 18. The cooling assembly includes a drive motor 26, which is fixedly installed on the left inner wall of the control box 1. A rotating rod 25 is fixedly connected to the right output end of the drive motor 26. A water suction box 23 is also fixedly installed on the upper inner wall of the control box 1. The rotating rod 25 extends rotatably into the water suction box 23. A rotating wheel 24 is fixedly installed at the right end of the rotating rod 25. A water suction pipe 38 and a water outlet pipe 1 are connected through the water suction box 23. The water suction pipe 38 passes through the isolation plate 35, and the water outlet pipe 1 is connected through the placement box 22.

[0032] Among them, the end of the placement box 22 away from the water outlet pipe is equipped with a return water pipe, which passes through the isolation plate 35 to form a complete water circulation loop.

[0033] The placement box 22 adopts a double-layer box structure, including an inner box and an outer box. The inner box integrates and installs core electrical control components such as controller, ultrasonic drive motherboard, and power voltage regulator module. There is a water passage gap between the outer box and the inner box, where water can circulate and achieve water cooling heat exchange, and the water flow does not directly contact the internal electrical components.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the ultrasonic generator provides ultrasonic welding power to the ultrasonic transducer 18 through electrical connection; during cooling, the drive motor 26 starts, and the drive motor 26 drives the rotating rod 25 and the rotating wheel 24 to rotate inside the water suction box 23, generating a negative pressure for water suction, so that the water under the isolation plate 35 is sucked in through the water suction pipe 38 and enters the gap between the inner and outer boxes of the placement box 22 through the water outlet pipe. The water after heat exchange flows back through the return water pipe to achieve continuous circulating water cooling heat dissipation, and removes the working waste heat generated by various electrical components and the ultrasonic generator in the inner box through heat exchange. Through the sandwiched water circulation heat exchange structure, the heat accumulated by the core components inside the placement box 22 can be continuously and efficiently dissipated, solving the problem of high temperature rise during long-term continuous operation of the equipment. This avoids defects such as signal disorder, unstable ultrasonic output, and component aging failure caused by high temperature, greatly improving the operational stability and accuracy of multi-axis linkage welding of the equipment, and effectively extending the service life of the core electrical components of the equipment.

[0035] Example 5: Based on Example 4 above, as follows Figures 5-8 As shown, an air inlet box 8 is fixedly installed on the upper end of the isolation plate 35. An air inlet pipe is connected to the left end of the air inlet box 8, and the air inlet pipe extends out of the control box 1. A rotating rod 28 is rotatably installed on the air inlet box 8. A bevel gear 46 is fixedly installed at both the upper and lower ends of the rotating rod 28. A bevel gear 43 is fixedly installed on the rotating rod 25. The bevel gear 43 meshes with the upper bevel gear 46. A bevel gear 47 meshes with the lower bevel gear 46. A fan blade 48 is fixedly installed on the right end of the bevel gear 47. Connecting blocks are symmetrically fixed on the left and right sides of the placement box 22. A vertical pipe 45 is fixedly installed on the side of the two connecting blocks that are far apart from each other. The upper and lower ends of the vertical pipe 45 are connected to a Π-shaped pipe 44. Several air outlet holes are opened on the side of the Π-shaped pipe 44 near the placement box 22. An air outlet pipe 52 is connected to the right end of the air inlet box 8. The air outlet pipe 52 is connected to one of the Π-shaped pipes 44.

[0036] The working principle and beneficial effects of the above technical solution are as follows: Rotating rod 25 rotates, driving bevel gear 2 43 to rotate, bevel gear 1 46 rotates together with bevel gear 2 43, thereby driving rotating rod 28 to rotate as a whole, and bevel gear 1 46 at the lower end drives bevel gear 3 47 and fan blade 48 to rotate, forming a negative pressure inside the air intake box 8. Outside air is drawn into the air intake box 8 through the air intake pipe, and the airflow is introduced into the interior of Π-shaped pipe 44 and vertical pipe 45 through the air outlet pipe 1 52, and is evenly sprayed out through several air outlet holes opened on the inner side of Π-shaped pipe 44, blowing on the outer wall surface of the placement box 22; The surrounding air-blowing structure with multiple air outlets through the Π-shaped tube 44 allows for all-round convection heat dissipation on the outer wall of the placement box 22. Based on the original water circulation cooling, the air-cooled convection further removes residual heat from the outer wall of the placement box 22, achieving a dual heat dissipation effect combining water cooling and air cooling. This continuously reduces the operating temperature of the control box 1 and its core components. Combined with the internal interlayer water circulation, this forms a composite heat dissipation system that combines internal and external cooling, significantly improving overall heat dissipation efficiency and effectively solving the problem of severe heat accumulation during long-term operation of the equipment.

[0037] Example 6: Based on Example 5 above, as follows Figures 5-6 , Figures 8-10As shown, a second water outlet pipe 27 is also connected through the water intake tank 23. The output end of the second water outlet pipe 27 is connected through the air intake tank 8, and its connection position is located to the left of the rotating rod 28. A fixing block 30 is fixedly installed on the lower side wall of the air intake tank 8. A water passage gap is provided between the fixing block 30 and the inner wall of the left side of the air intake tank 8. A tailwater pipe is installed on the lower side of the air intake tank 8, and the tailwater pipe passes through the isolation plate 35. An second air outlet pipe 31 is connected through the right end of the air intake tank 8. The second air outlet pipe 31 passes through the isolation plate 35 and is fixedly connected to the inner wall of the left side of the control box 1. A first pipe 32 is rotatably connected through the second air outlet pipe 31. A jet pipe 33 is connected through the right end of the first pipe 32. A second pipe 34 is connected through the right end of the jet pipe 33. The second pipe 34 is rotatably connected to the control box 1. Several jet nozzles 53 are installed on the jet pipe 33.

[0038] The spray nozzle 53 is positioned towards the lower surface of the placement box 22, which can provide uniform low-temperature heat dissipation to the bottom of the placement box 22.

[0039] The working principle and beneficial effects of the above technical solution are as follows: the cooling water in the water intake box 23 can be sent into the air intake box 8 through the water outlet pipe 27. The water will flow down evenly to form a water curtain. The air passes through the water curtain to complete the full water-air heat exchange, effectively reducing the airflow temperature. The water flow after heat exchange enters the water passage gap between the fixed block 30 and the left inner wall of the air intake box 8, and is finally discharged through the tail water pipe. The low-temperature airflow in the air intake box 8 after being cooled by the water curtain is transported by the air outlet pipe 21 to the pipe 1 32, the jet pipe 33 and the pipe 2 34. Finally, it is sprayed out by several nozzles 53 on the jet pipe 33 to achieve heat dissipation at the bottom of the placement box 22. The water curtain-type water-air heat exchange structure has a large heat exchange contact area, which can quickly cool the circulating airflow. At the same time, the jet head 53 eliminates the heat dissipation blind spot at the bottom of the placement box 22. Combined with the previous side wall air cooling and sandwich water cooling structure, a water-air composite heat dissipation structure with full coverage of the top, sides and bottom is formed, making heat dissipation more efficient.

A toothed plate 49 is fixedly mounted at the lower end of the drive rod 29. A gear 50 is fixedly mounted on the pipe 32. The gear 50 meshes with the toothed plate 49.

[0041] Preferably, a bevel gear 55 is fixedly installed on pipe 2 34, and bevel gear 2 54 is meshed with the upper end of bevel gear 1 55; the rotating pipe 14 rotates through the isolation plate 35, bevel gear 2 54 is fixedly installed on the rotating pipe 14, a hose 51 is connected through the air outlet pipe 2 31, the other end of the hose 51 is rotatably connected through the rotating pipe 14, water-absorbing cotton 36 is installed inside the rotating pipe 14, and an electric control valve 37 is also installed on the rotating pipe 14, which is electrically connected to the point control button 21; the rotating pipe 14 also has several air holes, which face the welding wire plate 5.

[0042] The working principle and beneficial effects of the above technical solution are as follows: When the rotating rod 25 rotates, it drives the gear 39 to rotate. The gear 39 drives the gear 42 to rotate, causing the extended rod 41 at the eccentric position of the gear 42 to make a circular motion. In conjunction with the square frame 40, the driving rod 29 is driven to slide up and down, thereby driving the toothed plate 49 to move up and down. The toothed plate 49, through meshing with the gear 50, drives the pipe 32 and the jet pipe 33 to swing back and forth as a whole, so that the jet head 53 blows air evenly to the lower surface of the placement box 22 in an oscillating manner to dissipate heat, further improving the uniformity of heat dissipation at the bottom.

[0043] In accordance with the structure of Embodiment 3, when the electric push rod 9 drives the clamping block 11 to move (the point control board 20 will contact the point control button 21 when it descends and rises), the point control board 20 touches the point control button 21, the circuit is turned on and the electric control valve 37 is triggered to open; at this time, the low-temperature airflow inside the second air outlet pipe 31 is introduced into the rotating pipe 14 through the hose 51, and after being dehumidified by the water-absorbing cotton 36, it is sprayed towards the wire bonding board 5 and the wire bonding assembly through the air holes of the rotating pipe 14 and the jet nozzle 17 on the corrugated hose 13, respectively, to blow and clean the wire bonding board 5, and to blow and dissipate heat in a directional manner on the wire bonding mechanism, so as to remove the residual heat generated by the welding operation in time. The rotating tube 14 can rotate to deliver air, removing fine welding slag and dust from the wire bonding board 5 (a first purging is performed before welding, and a second purging is performed after welding). The corrugated hose 13 can dissipate heat at specific points on the wire bonding assembly. Combined with the internal jacketed water cooling, all-area air cooling, and water curtain cooling structure, a comprehensive heat dissipation system is formed for the whole machine, effectively solving the problems of internal heat accumulation and high temperature operation of the wire bonding assembly during long-term operation.

[0044] Example 8: A welding method using a multi-axis linkage intelligent wire bonding device, comprising the following steps: S1: Place the workpiece to be welded on the welding wire plate 5, fix it with a vacuum suction cup, and place the welding wire at the welding position. S2: The control box drives the X-axis assembly, Y-axis assembly and Z-axis assembly to bring the wire bonding mechanism into position, the clamping block 11 clamps the workpiece and starts the cooling assembly; S3: The transducer drives the cutting tool to complete the welding. The cooling components work synchronously. After the welding is completed, all mechanisms reset and the workpiece is removed.

[0045] The working principle and beneficial effects of the above technical solution are as follows: the workpiece to be welded is placed on the welding plate 5, the vacuum suction cup is used to clamp and fix it, and the welding wire is placed in the welding position; the control box drives the X-axis assembly, Y-axis assembly and Z-axis assembly to drive the welding mechanism into position, the clamping block 11 clamps the workpiece and starts the cooling assembly; the transducer drives the cutting tool to complete the welding, the cooling assembly works synchronously, and after the welding is completed, each mechanism is reset and the workpiece is removed.

[0046] Negative pressure adsorption fixation effectively prevents workpiece loosening and displacement, providing a stable processing foundation for high-precision welding; intelligent linkage between welding and heat dissipation processes eliminates the need for manual intervention; multiple heat dissipation structures remove residual heat generated during equipment operation in real time, preventing heat accumulation and temperature rise during continuous operation, effectively improving the operational stability of continuous operation, extending the overall service life of the equipment, and better meeting the needs of long-term, high-precision wire welding operations.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
