Description

Technical Field

[0001] This utility model relates to the technical field of bonding silver wire production equipment, and in particular to a rotary bonding silver wire process switching device. Background Technology

[0002] Silver bonding wire is a key material used in microelectronic packaging and semiconductor device manufacturing. It is mainly used to electrically connect the electrodes of chips (such as integrated circuits, LEDs, power devices, etc.) to external lead frames or substrates. Since the production of silver bonding wire involves multiple process steps, such as wire drawing, annealing, and plating, traditional methods may use multiple independent devices, resulting in low efficiency, large space occupation, and complex operation. Therefore, a device that can quickly switch between different processes is needed to reduce downtime and improve production efficiency.

[0003] Traditional equipment typically requires tools and involves cumbersome procedures when replacing or repairing process modules. Improper operation during disassembly can lead to inaccurate positioning or even loosening, all of which can cause production interruptions and increase costs and risks. Utility Model Content

[0004] The purpose of this invention is to solve the problem that changing process modules in traditional equipment requires tools and involves cumbersome steps, and to propose a rotary bonding silver wire process switching device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rotary bonding silver wire process switching device includes a base and a turntable rotatably connected to the base. The turntable has a mounting base inserted into it, a control channel is provided on it, a locking block is slidably connected in the control channel, and a slot corresponding to the locking block is provided on the mounting base. A flow guiding vortex cavity is provided at the center of the turntable and is connected to the control channel.

[0006] To facilitate disassembly of the mounting base, preferably, the control channel includes a control cavity and a drive cavity disposed inside the turntable, wherein the control cavity and the drive cavity are connected, and a spring is disposed inside the drive cavity, and the spring disposed inside the drive cavity is fixedly installed with the end of the locking block away from the mounting base.

[0007] To facilitate pushing the card block, the turntable is further provided with a connecting cavity inside. One end of the connecting cavity is connected to the guide vortex cavity, and the other end of the connecting cavity is connected to the control cavity. The control cavity is provided with an electromagnetic reversing valve, and the connecting cavity is located on the side near the air inlet end of the electromagnetic reversing valve.

[0008] To achieve airflow, preferably, an air intake channel is provided on the outer side of the turntable, wherein the air intake end of the air intake channel is connected to an outer air intake device, and an air intake chamber and an air outlet chamber are respectively provided inside the turntable. The air intake channel is connected to the air intake chamber, the air outlet end of the air intake chamber is connected to the initial end of the guide vortex chamber, the end of the guide vortex chamber is connected to the air outlet chamber, and a control valve is provided at the end of the air outlet chamber.

[0009] To facilitate driving the turntable, preferably, a servo motor is fixedly installed inside the base, a gear is fixedly installed at the output end of the servo motor, and the outer side of the turntable is provided with matching gear teeth.

[0010] To enable switching between multiple workstations, preferably, multiple mounting bases are provided, and all multiple mounting bases are arranged equidistantly in a ring on the turntable with the central axis of the turntable as the reference.

[0011] To facilitate the positioning of the bonding silver wire, preferably, a positioning frame is provided on the upper surface of the base, and guide wheels are symmetrically arranged on the inner side of the positioning frame. The positioning frame is symmetrically arranged on the left and right sides of the base with the center line of the base as the reference.

[0012] Compared with the prior art, this utility model provides a rotary bonding silver wire process switching device, which has the following beneficial effects: 1. This rotary bonding silver wire process switching device uses slots on both sides of the mounting base to engage with locking blocks. When the device needs to be locked, the control chip in the electromagnetic reversing valve creates a passage between the control chamber, drive chamber, and connecting chamber. The gas entering the connecting chamber further pressurizes the control and drive chambers, thereby changing the air pressure and pushing the locking blocks into the slots, thus locking the mounting base. Conversely, when the electromagnetic reversing valve changes the passage, the air pressure inside the control and drive chambers decreases, and the spring deformation pulls the locking blocks back to their original position, achieving quick disassembly of the mounting base, shortening the disassembly time, and improving efficiency.

[0013] 2. This rotary bonding silver wire process switching device uses a guide vortex cavity in conjunction with an external air intake device to improve the airflow effect inside the turntable, thereby achieving the purpose of cooling the turntable. On the other hand, it can pressurize the air inside the drive cavity by using multiple air outlets opened in the guide vortex cavity in conjunction with the connecting cavity, thereby causing the locking block to move and lock the mounting base.

[0014] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model can achieve quick disassembly of the mounting base above the turntable, improve maintenance or replacement efficiency, and avoid the time-consuming and labor-intensive situation of traditional equipment requiring tools for disassembly.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Example: Reference Figures 1-6A rotary silver wire bonding process switching device includes a base 1, a positioning frame 19 on the upper surface of the base 1, guide wheels symmetrically arranged on the inner side of the positioning frame 19, and the positioning frame 19 symmetrically arranged on the left and right sides of the base 1 with the center line as the reference. The mounting frames on the left and right sides of the base 1 clamp the silver wire to be processed and achieve the positioning effect, improving the stability of the silver wire bonding process and avoiding large processing errors caused by displacement. The device also includes a turntable 2 rotatably connected to the base 1, wherein a mounting base 3 is inserted into the turntable 2, and a control channel is provided on the turntable 2. The inner sliding connection includes a locking block 4, and the mounting base 3 has a corresponding slot 5. The guide vortex cavity 6 is vortex-shaped and located at the center of the turntable 2. The guide vortex cavity 6 is connected to the control channel. When the guide vortex cavity 6 is connected to the external air intake device, the external air intake device causes gas to flow into the guide vortex cavity 6. Subsequently, some of the gas inside the guide vortex cavity 6 enters the control channel, further increasing the air pressure inside the control channel, thereby pushing the locking block 4 closer to the mounting base 3. When the locking block 4 is inserted into the slot 5, it locks the mounting base 3, ensuring a stable effect after the process module is installed on the mounting base 3.

[0020] Specifically, the slots 5 on both sides of the mounting base 3 work in conjunction with the locking blocks 4. When the equipment needs to be locked, the control chip in the electromagnetic reversing valve 10 creates a passage between the control chamber 7, the drive chamber 8, and the connecting chamber 11. The gas entering the connecting chamber 11 pressurizes the control chamber 7 and the drive chamber 8, thereby changing the air pressure and pushing the locking blocks 4 into the slots 5, thus locking the mounting base 3. Conversely, when the electromagnetic reversing valve 10 changes the passage, the air pressure inside the control chamber 7 and the drive chamber 8 decreases, and the spring 9 deforms and pulls the locking blocks 4 back to their original position. This achieves quick disassembly of the mounting base 3, shortens the disassembly time, improves efficiency, and avoids situations where the mounting base 3 is mispositioned or even loose due to improper operation.

[0021] The control channel includes a control cavity 7 and a drive cavity 8 located inside the turntable 2. The control cavity 7 is connected to the drive cavity 8. A spring 9 is installed inside the drive cavity 8. The spring 9 located inside the drive cavity 8 is fixedly installed with the end of the locking block 4 away from the mounting base 3.

[0022] When in use, if the mounting base 3 needs to be removed, firstly, the gas inside the guide vortex cavity 6 is discharged through the end, thereby reducing the air pressure inside the control channel and reducing the pressure on the locking block 4. Then, the spring 9 rebounds due to its own elasticity, pulling the locking block 4 back into the drive cavity 8 until the locking block 4 is pushed out of the slot 5, thus realizing the unlocking action of the mounting base 3. Then the mounting base 3 can be removed, thereby achieving the effect of quick removal.

[0023] The turntable 2 has a connecting cavity 11 inside. One end of the connecting cavity 11 is connected to the guide vortex cavity 6, and the other end of the connecting cavity 11 is connected to the control cavity 7. The control cavity 7 is equipped with an electromagnetic reversing valve 10, and the connecting cavity 11 is located on the side close to the air inlet end of the electromagnetic reversing valve 10.

[0024] Specifically, a power supply 18 is installed at the bottom of the turntable 2. The power supply 18 is electrically connected to the control chip inside the solenoid directional valve 10 via a cable, thereby enabling the solenoid directional valve 10 to switch the air passages within the cavity according to the control chip. The solenoid directional valve 10 has an outlet and an inlet on the side near the drive cavity 8. When the mounting base 3 needs to be locked, the control chip controls the solenoid directional valve 10 to open its outlet. Then, the gas enters through the inlet of the solenoid directional valve 10 and is further discharged into the drive cavity 8 through the outlet, increasing the air pressure inside the drive cavity 8. Conversely, the gas is discharged through the outlet. The control chip controls the electromagnetic reversing valve 10 to switch the air passage and open the air inlet. The gas in the drive chamber 8 enters through the air inlet and exits through the air inlet of the electromagnetic reversing valve 10. Finally, the gas flows into the guide vortex cavity 6 through the connecting cavity 11. The guide vortex cavity 6 is used in conjunction with the air inlet device on the outside of the equipment. On the one hand, it improves the air flow effect inside the turntable 2, thereby achieving the purpose of cooling the turntable 2. On the other hand, the multiple air outlets opened in the guide vortex cavity 6 cooperate with the connecting cavity 11 to pressurize the air inside the drive chamber 8, thereby moving the locking block 4 to lock the mounting base 3.

[0025] An air intake channel 14 is provided on the outer side of the turntable 2. The air intake end of the air intake channel 14 is connected to the outer air intake device. An air intake chamber 12 and an air outlet chamber 13 are respectively provided inside the turntable 2. The air intake channel 14 is connected to the air intake chamber 12. The air outlet end of the air intake chamber 12 is connected to the initial end of the guide vortex chamber 6. The end of the guide vortex chamber 6 is connected to the air outlet chamber 13. A control valve is provided at the end of the air outlet chamber 13.

[0026] Specifically, the air intake channel 14 is connected to the external air intake device. The external air intake device allows gas to flow into the air intake channel 14. Subsequently, the gas inside the air intake channel 14 is compressed and flows into the guide vortex cavity 6 through the air intake chamber 12. Then, the opening and closing state of the control valve at the end of the air outlet chamber 13 allows the gas in the guide vortex cavity 6 to achieve a flow effect, thereby reducing the temperature of the turntable 2. On the other hand, when the air outlet chamber 13 is closed, the gas pressure in the guide vortex cavity 6 increases, and then flows into the control channel through the connecting chamber 11, thereby pressurizing the air inside the control channel and causing the locking block 4 to move and lock towards the mounting base 3 due to the gas pressure.

[0027] A servo motor 15 is fixedly installed inside the base 1, and a gear 16 is fixedly installed at the output end of the servo motor 15. The outer side of the turntable 2 is provided with matching gear teeth 17 corresponding to the gear 16.

[0028] Specifically, the servo motor 15 is a Siemens SINAMICS S210 series motor, which ensures that the positioning error of the device driving the turntable 2 is within 0.03 degrees, thus ensuring the accuracy of the bonding silver wire processing.

[0029] The number of mounting bases 3 is 3 to 9, and the preferred number in this application is 7. The multiple mounting bases 3 are arranged in a ring at equal intervals on the turntable 2 with the central axis of the turntable 2 as the reference. The screw slots provided on the mounting bases 3 allow the installation of process modules on top of them, thereby enabling multiple processing requirements to be realized on this device, avoiding excessive machine space occupation and the problem of machine downtime during line operation.

[0030] In this invention, the mounting base 3 is first inserted into the corresponding groove of the turntable 2. Then, the external air intake device delivers air into the air intake channel 14. The air then enters the guide vortex cavity 6 through the air intake cavity 12. At this time, the control valve in the outlet cavity 13 is closed. Then, the gas enters the control cavity 7 through the connecting cavity 11. Then, the control chip in the electromagnetic reversing valve 10 controls the air inlet and outlet of the electromagnetic reversing valve 10 to open. The gas then enters the drive cavity 8 through the control cavity 7. Due to the increased air pressure in the drive cavity 8, the locking block 4 is pressured and moves towards the mounting base 3 until the locking block 4 enters the locking groove 5 and locks the mounting base 3. Then, the electromagnetic reversing valve 10 is controlled again to close the air inlet of the electromagnetic reversing valve 10. Then, the control valve in the outlet cavity 13 works to open the outlet cavity 13. Then, the air is discharged through the outlet cavity 13 after passing through the guide vortex cavity 6, so that the air can be circulated and the temperature of the turntable 2 is reduced. If the mounting base 3 needs to be removed, simply connect the air inlet and air port of the electromagnetic reversing valve 10 again through the built-in control chip of the electromagnetic reversing valve 10. Then, the air in the control chamber 7 and the drive chamber 8 flows into the guide vortex chamber 6 due to the pressure difference. As the pressure in the drive chamber 8 decreases, the pressure on the locking block 4 decreases accordingly. Furthermore, the spring 9 deforms and pulls the locking block 4 to retract into the drive chamber 8, thus removing the mounting base 3. This achieves the purpose of quick removal of the mounting base 3 and makes it convenient to use.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
