Description

Technical Field

[0001] This invention relates to the field of ultrasonic welding of non-ferrous metals, and particularly to an intelligent ultrasonic welding device for non-ferrous metals. Background Technology

[0002] Ultrasonic welding is an industrial technology that uses ultrasonic welding equipment to locally apply high-frequency ultrasonic waves, generating high-frequency vibration waves that are transmitted to the metal surfaces to be welded. Under pressure, the two metal surfaces rub against each other, forming a fusion between molecular layers. Compared with high-frequency welding, ultrasonic metal welding has the advantages of being fast, energy-saving, having high fusion strength, good conductivity, producing no sparks, and being close to cold processing. It is suitable for non-ferrous metal materials such as nickel sheets, aluminum foil, aluminum sheets, and copper sheets with a thickness of less than 2cm. For example, the welding of relay silver contacts to a copper substrate can achieve a contact resistance of ≤0.5MΩ through ultrasonic welding, meeting high reliability requirements, and eliminating the need for additional solder.

[0003] Existing ultrasonic welding devices with silver contacts have several technical drawbacks. First, the connection surface between the silver terminals and the copper substrate is often contaminated with oil. This oil reduces the efficiency of ultrasonic vibration energy transmission on the metal surface, resulting in insufficient frictional heat generation in the welding area, affecting molecular layer fusion. Burning the oil can also produce bubbles or oxide layers, causing weak welds, reduced strength, and even contamination of the welding head. Currently, there is a lack of automated degreasing devices, making the pre-welding degreasing process cumbersome and ineffective. Second, although ultrasonic welding is a cold-state welding process, the high-frequency vibration and frictional heat conduction between the metals can cause the welding head to reach a high temperature. Failure to dissipate heat in time will shorten the lifespan of the welding head. Third, because the high-frequency vibration during welding produces frictional noise or howling, ultrasonic welding generates more noise pollution than conventional welding methods. Existing noise reduction measures are costly, bulky, and complex, making them less applicable to ultrasonic welding devices.

[0004] In summary, considering that existing facilities cannot meet the needs of work, we propose an intelligent ultrasonic welding device for non-ferrous metals. Summary of the Invention

[0015] In a preferred embodiment of the intelligent ultrasonic welding device for non-ferrous metals described in this invention, a double-headed liquid storage tank is installed on the upper surface of the automatic cleaning base. The double-headed liquid storage tank stores clean water and degreasing agent respectively.

[0017] As a preferred embodiment of the intelligent ultrasonic welding device for non-ferrous metals described in this invention, a vacuum sealing cover is fixed at the lower end of the lifting pressure rod and located outside the ultrasonic welding head. A noise-absorbing gap is formed between the vacuum sealing cover and the ultrasonic welding head. An annular compression airbag is provided at the bottom of the vacuum sealing cover. The annular compression airbag passes through the clamping port and acts on the upper surface of the movable tooling base and the contact element.

[0018] In a preferred embodiment of the intelligent ultrasonic welding device for non-ferrous metals described in this invention, a vacuum pump is vertically installed at the lower position of the ultrasonic welding machine. A corrugated telescopic tube is connected to the interface of the vacuum pump. The corrugated telescopic tube extends into the interior of the lifting pressure rod. A suction positioning tube is connected to the lower end of the corrugated telescopic tube. A tubular silencer is installed inside the suction positioning tube. The lower end of the suction positioning tube is fixed to a positioning plate. A perforated suction head is installed on the lower end face of the positioning plate. Several sets of suction dividing holes communicating with the silencer gap are evenly distributed on the perforated suction head. The number of suction dividing holes is preferably 6-12 sets.

[0019] In a preferred embodiment of the intelligent ultrasonic welding device for non-ferrous metals described in this invention, a liquid collection tray is provided at the bottom of the inner receiving tank, and a drain pipe extending out of the automatic cleaning seat is provided at the lower end of the liquid collection tray.

[0020] This invention provides an intelligent ultrasonic welding device for non-ferrous metals, which has the following significant improvements and advantages compared with the prior art: The design incorporates movable clamps. On one hand, several sets of movable clamps simultaneously contact the silver terminals, centering and aligning them with the terminal slots of the contact elements. On the other hand, these movable clamps simultaneously retract to a rearward position within the inner sealing sleeve, disengaging from the air ports. The atomized liquid in the annular atomization channel overflows from these ports, passes through the outer sealing sleeve, and enters the clamping opening from different directions, acting evenly on the ultrasonic welding head to cool it down promptly, thus achieving heat dissipation and improving the overall cooling effect.

[0021] The first servo motor is started, and the large gear is decelerated and rotated through the transmission. The circular clamp makes a circular motion. On the one hand, the circular clamp drives the silver terminal to rotate, and the upper and lower degreasing rollers are used to thoroughly degrease and clean the silver terminal, increasing the cleaning range. On the other hand, it accelerates the rapid dispersion of the atomized liquid in the upper and lower annular atomizing channels, improving the uniformity and rate of heat dissipation.

[0022] The second servo motor is started, driving the lower degreasing roller to rotate, and through transmission, the upper degreasing roller rotates synchronously, making full use of the degreasing roller to achieve the purpose of cleaning while rotating, thus improving the cleaning effect; the power of the lower degreasing roller causes the first bevel gear to rotate, and through meshing with the second bevel gear, the rotating rod of the rotary degreasing device rotates, using several sets of degreasing cloth strips with degreasing agent to make circular motion, performing comprehensive degreasing and cleaning of the terminal slots of the contact elements, with a high degree of automation and intelligence.

[0023] The vacuum sealing cover passes through the clamping port by means of the lifting and lowering movement. The annular extrusion airbag contacts the upper surface of the moving tooling seat and contact element. The contact force flattens the annular extrusion airbag and seals the bottom of the noise reduction gap, creating conditions for vacuum suction noise reduction. It also has a simple structure, small size, and reduced cost.

[0024] The vacuum pump is started, and suction is generated using the perforated suction head. On one hand, the suction dividing holes on the perforated suction head draw in the air carrying sound energy within the silencer gap, dispersing the sound energy within the perforated suction head to reduce noise. As the air flows upward through the suction positioning tube, the tubular silencer converts the sound energy into heat energy through sound-absorbing materials and a reactive structure, effectively reducing mid-to-high frequency noise and creating a vacuum state in the silencer gap. The vacuum characteristics further block the propagation of noise, improving the noise reduction effect. On the other hand, when the atomized liquid dissipates heat from the ultrasonic welding head, the atomized liquid accumulates in the silencer gap. The vacuum pump draws in the heat-carrying atomized liquid and discharges it outward through the corrugated expansion tube, creating an airflow state, thereby assisting in accelerating the heat dissipation speed. The process is highly automated and intelligent. Attached Figure Description

A first control valve and a second control valve are installed on the double-connector at the bottom of the double-headed liquid storage tank 80. Two sets of liquid filling and sealing caps 81 are symmetrically arranged on the upper end of the double-headed liquid storage tank 80.

Several sets of spray holes 91 are evenly distributed on the lower part of the spray horizontal pipe 90, acting on the upper oil removal roller 61. A guide space 92 is formed between the spray horizontal pipe 90 and the upper oil removal roller 61. Figure 12 As shown.

[0046] Furthermore, a guide pipe 93 is vertically connected to one end of the guide space 92, forming a liquid channel (the liquid channel is relatively narrow) between the lower degreasing roller 63 and the lower cleaning housing 62. The lower end of the guide pipe 93 is connected to the liquid channel, and the end of the liquid channel away from the guide pipe 93 is connected to the liquid inlet 77. Figure 12 As shown.

[0047] Furthermore, a liquid collection tray 86 is provided at the bottom of the inner storage tank 52, and a drain pipe 87 extending out of the automatic cleaning seat 51 is provided at the lower end of the liquid collection tray 86. Figure 7 As shown.

[0048] In this embodiment, the welding fixture 5 is positioned at the left end of the linear limiting groove 2. The contact element 24 is placed in the welding positioning groove 23 for positioning. Then, the silver terminal 37 is placed in the clamping opening 36, and the silver terminal 37 is centered using several sets of movable clamping rods 41, so that the terminal slots of the silver terminal 37 and the contact element 24 are aligned vertically. At this time, the lead screw motor is started, and the long lead screw 4 rotates, causing the moving fixture seat 20 to move linearly to the right. When the moving fixture seat 20 passes through the inside of the connecting frame 50 (only when the silver terminal 37 and the contact element 24 have oil stains and need to be cleaned, otherwise it can pass directly through the connecting frame 50), the height of the drive table 30 is adjusted by the extension and retraction of the two sets of hydraulic rods 26 (to ensure that the upper degreasing roller 61 and the upper end face of the silver terminal 37 are in contact, and to ensure that the lower degreasing roller 63 and the lower end face of the silver terminal 37 are in contact).

[0049] When the drive cylinder 53 is activated, the cylinder rod 54 drives the double-headed connecting seat 55 to extend out of the inner receiving groove 52, so that the upper degreasing roller 61 and the lower degreasing roller 63, which are coated with degreasing agent, come into contact with the upper and lower end faces of the silver terminal 37, respectively, and the ends of the two sets of degreasing rollers are close to the center of the silver terminal 37. At this time, the first servo motor 35 is activated, causing the pinion 34 to rotate, and through meshing, the large gear 33 is decelerated and rotated, thereby causing the circular clamp 31 to drive the silver terminal 37 to rotate. The upper degreasing roller 61 and the lower degreasing roller 63 are used to thoroughly degrease and clean the silver terminal 37. At the same time, the second servo motor 66 is activated, driving the lower degreasing roller 63 to rotate, and through the connection of the sprocket 67 and the chain 68, the upper degreasing roller 61 rotates synchronously, making full use of the degreasing rollers to achieve the purpose of cleaning while rotating, thereby improving the cleaning effect.

[0050] When the upper degreasing roller 61 and the lower degreasing roller 63 are in contact with the upper and lower end faces of the silver terminal 37 respectively, the rotary degreasing device 70 moves just above the terminal slot of the contact element 24. The rotation of the lower degreasing roller 63 causes the first bevel gear 69 to rotate. Through meshing with the second bevel gear 74, the rotating rod 72 of the rotary degreasing device 70 rotates. Several sets of degreasing cloth strips 75 with degreasing agent make circular motion to thoroughly degrease and clean the terminal slot of the contact element 24.

[0051] Then, the cylinder rod 54 drives the double-headed connecting seat 55 back into the inner receiving groove 52. When too much oil accumulates on the upper oil removal roller 61 and the lower oil removal roller 63, the first control valve is opened. First, the clean water in the double-headed liquid storage tank 80 enters the hose 85 through air pressure and flows in the spray horizontal pipe 90, spraying out from several sets of spray holes 91 to thoroughly rinse the rotating upper oil removal roller 61, removing the oil-containing degreasing agent from its surface and forming a mixture. Most of the mixture flows in the guide space 92 (a small portion leaks downwards from the gaps), and is injected into the liquid channel through the guide pipe 93. When the mixture... When flowing in the channel, the rotating lower degreasing roller 63 comes into full contact with the mixed liquid, washing away the oil-containing degreasing agent on the surface of the lower degreasing roller 63. Then, the mixed liquid enters the rod cavity 76 from the inlet 77 for temporary storage. As the rotating rod 72 rotates, the mixed liquid is slowly centrifugally ejected from several sets of spray holes 78, washing several sets of degreasing cloth strips 75 and removing the oil-containing degreasing agent from the surface of the degreasing cloth strips 75. Then, the mixed liquid drips downward into the collection tray 86 and is discharged outward from the drain pipe 87. (It should be noted that since the clean water flows continuously along the above path, the cleaning time is relatively long, so there is no cross-contamination.)

[0052] After rinsing with clean water, open the second control valve to allow the degreasing agent in the double-headed storage tank 80 to enter the hose 85 through air pressure. Following the same flow path, apply new degreasing agent to the upper degreasing roller 61, the lower degreasing roller 63, and several sets of degreasing cloth strips 75 in sequence for the next use. (It should be noted that during the application process, a large amount of degreasing agent will not adhere and will enter the collection tray 86. At this time, the drain pipe 87 is used to collect it for recycling.)

[0053] Next, the movable fixture 20 continues to move straight to the right and stops below the ultrasonic welding machine 11. First, the two sets of hydraulic rods 26 retract, adjusting the drive table 30 to move downwards towards the welding positioning groove 23. Then, several sets of movable clamping rods 41 retract into the outer sealing sleeve 40, releasing the silver terminal 37 to fall into the terminal slot of the contact element 24 (the falling distance is relatively short). Immediately, the lifting pressure rod 12 drives the ultrasonic welding head 13 through the clamping port 36, pressing it against the upper surface of the silver terminal 37. The transducer inside the ultrasonic welding machine 11 receives and transmits signals. The high-frequency electrical signal from the generator produces mechanical vibration through the piezoelectric effect or magnetostriction effect. The amplitude transformer amplifies the vibration amplitude and transmits it to the ultrasonic welding head 13. The ultrasonic welding head 13 concentrates the high-frequency vibration on the contact surface between the silver terminal 37 and the contact element 24. Micro-friction is generated on the contact surface, causing violent movement between material molecules. The frictional heat causes the local temperature of the material to rise rapidly to the melting point. The molten material molecules diffuse and penetrate each other, forming intermolecular bonds. After the vibration stops, it is maintained for 1-3 seconds. The material cools and solidifies under pressure, completing the welding process.

[0054] At this point, the lifting pressure rod 12 drives the ultrasonic welding head 13 to rise, with the bottom of the ultrasonic welding head 13 positioned slightly above the clamping port 36. This causes the ultrasonic transducer inside the annular atomizing channel 42 to operate, generating atomized liquid. Simultaneously, the entire circular clamp 31 undergoes circular motion, accelerating the rapid dispersion of the atomized liquid within the upper and lower annular atomizing channels 42. Then, several sets of movable clamping rods 41 simultaneously retract to a rearward position within the inner sealing sleeve 44, causing the movable clamping rods 41 to leave the air port 45. Due to dispersion, the atomized liquid within the annular atomizing channel 42 overflows from several sets of air ports 45, passes through the outer sealing sleeve 40, and enters the clamping port 36 from different directions, acting evenly on the ultrasonic welding head 13 to cool it down and achieve heat dissipation. Example 2

[0055] Based on Example 1, ultrasonic welding generates more noise pollution than conventional welding methods due to the frictional sound or whistling caused by high-frequency vibrations during welding. Existing noise reduction measures are costly and have limited applicability to ultrasonic welding equipment. To address this issue, we have the following design: Figures 13-15 As shown.

[0056] Specifically, a vacuum sealing cover 100 is fixed to the lower end of the lifting pressure rod 12 and outside the ultrasonic welding head 13. A noise-absorbing gap 102 is formed between the vacuum sealing cover 100 and the ultrasonic welding head 13. An annular compression airbag 101 is provided at the bottom of the vacuum sealing cover 100. The annular compression airbag 101 passes through the clamping port 36 and acts on the upper end face of the movable tooling base 20 and the contact element 24. The annular compression airbag 101 and the clamping port 36 are fitted together. Figure 13 and Figure 14 As shown.

[0057] Furthermore, a vacuum pump 110 is vertically mounted at the lower position of the ultrasonic welding machine 11. A corrugated telescopic tube 111 is connected to the interface of the vacuum pump 110, which can extend and retract with the movement of the lifting pressure rod 12. The corrugated telescopic tube 111 extends into the interior of the lifting pressure rod 12, such as... Figure 15 As shown.

[0058] The lower end of the corrugated expansion tube 111 is connected to an air intake positioning tube 112. A tubular silencer 113 is installed inside the air intake positioning tube 112. The tubular silencer 113 includes sound-absorbing material and a resistive structure. The lower end of the air intake positioning tube 112 is fixed to a positioning plate 114. A perforated suction head 115 is installed on the lower end face of the positioning plate 114. Several sets of air intake dividing holes 116, which communicate with the silencing gap 102, are evenly distributed on the perforated suction head 115. Figure 14 and Figure 15 As shown.

[0059] In this embodiment, when the ultrasonic welding head 13 passes through the clamping port 36 and presses against the upper surface of the silver terminal 37, the outer vacuum sealing cover 100 also passes through the clamping port 36. The annular extrusion airbag 101 contacts the upper surface of the movable tooling seat 20 and the contact element 24. The contact force flattens the annular extrusion airbag 101, sealing the bottom of the silencing gap 102. During welding, the vacuum pump 110 is started in advance or simultaneously. The suction dividing hole 116 on the perforated suction head 115 is used to draw in the air carrying sound energy in the silencing gap 102. The sound energy is dispersed into the perforated suction head 115, achieving the purpose of reducing noise. At the same time, when the air flows upward through the suction positioning tube 112, the tubular silencer 113 converts the sound energy into heat energy through the sound-absorbing material and the resistive structure, effectively reducing mid-to-high frequency noise and creating a vacuum state in the silencing gap 102. The vacuum characteristics are used to further block the propagation of noise.

[0060] After welding, the bottom of the ultrasonic welding head 13 and the annular extrusion airbag 101 are moved back to the upper position inside the clamping port 36. When the ultrasonic welding head 13 is cooled by the atomizing liquid, the atomizing liquid accumulates in the silencing gap 102. The vacuum pump 110 draws the heat-carrying atomizing liquid out through the corrugated telescopic tube 111, forming an airflow state, thereby helping to accelerate the heat dissipation speed.
