Description

Technical Field

[0001] This utility model belongs to the field of welding equipment, and specifically relates to an ultrasonic welding device. Background Technology

[0002] Ultrasonic welding of automotive wiring harnesses is a welding method that uses ultrasonic technology, primarily used for connecting automotive wiring harnesses. An automotive wiring harness refers to a collection of wires and connectors used in an automotive electrical system to transmit electrical signals and power.

[0003] The principle of ultrasonic welding of automotive wiring harnesses is to apply a certain welding pressure to the two wires at the welding point through an ultrasonic welding head. Then, the ultrasonic welding head generates local high temperature through high-frequency vibration, causing the surface of the wires to melt. In the molten state, the intermolecular forces of the wires cause the two wires to cross-link, forming a welded connection. After welding is completed, the welding head stops vibrating, and the welded area cools and solidifies, forming a strong weld point. For example, the invention patent application with publication number CN108127243A proposes an ultrasonic welding device, including a base, a fixed frame, a controller, a lifting device, a guide rod, a slider, a mounting frame, a welding device, a telescopic device, a slider rail mechanism, a baffle, and a carrying plate. The fixed frame is installed above the base, the controller is installed on the left side of the fixed frame, the guide rod is installed on the upper end of the fixed frame, the slider is installed on the guide rod, the lifting device is installed on the lower surface of the slider, the mounting frame is installed at the lower end of the lifting device, and the welding device is connected to the mounting frame on the left and right sides through the slider rail mechanism, and to the mounting frame on the rear side through the telescopic device.

[0004] Existing ultrasonic welding equipment is prone to slipping on the worktable due to machine vibration, making it unstable. Furthermore, the wiring harness can detach due to vibration, affecting the welding process. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasonic welding device that solves the problems of existing ultrasonic welding devices, which are prone to slipping on the worktable due to machine vibration, are not stable enough, and have wire harnesses that can come loose due to vibration, affecting welding.

[0006] To achieve the above objectives, this utility model provides an ultrasonic welding device, including a base, a mounting seat welded to the upper edge of the base, an ultrasonic welding head provided on the front of the mounting seat, two arch clamping blocks slidably connected inside the base, a motor I fixedly mounted on the top inner side of the base, a rotating disk fixedly connected to the end of the output shaft of the motor I, a fixing sleeve fixedly connected to the top inner side of the base and on both sides of the motor I, a wedge block slidably connected inside the fixing sleeve, the wedge block slidably connected to the arch clamping blocks, a sliding rod fixedly connected to the bottom of the wedge block, the sliding rod passing through the fixing sleeve and slidably connected to the fixing sleeve, the end of the sliding rod passing through the rotating disk and slidably connected to the rotating disk, a support plate fixedly connected to the inner side of the base, a guide rod fixedly connected to the upper end of the support plate and below the arch clamping blocks, the guide rod slidably connected to the arch clamping blocks, and a spring sleeved on the outer side of the guide rod.

[0007] The principle of this utility model is as follows: When in use, first start the second motor, the second motor drives the threaded shaft to rotate, and the linkage plate rises under the guidance of the guide column. Then the linkage plate pulls the piston through the connecting rod, thereby sucking the air inside the suction cup and adsorbing it onto the worktable, so that the device remains stable and is not easy to slip due to the vibration of the device itself.

[0008] The two wire harnesses are then threaded onto the inside of the arch clamp block and placed on the wire harness seat. The ends of the two wire harnesses are then placed together on the connector seat. The motor drives the rotating disk to rotate, and as the rotating disk rotates, the sliding rod is pushed radially by the rotating disk. The sliding rod then moves the wedge block laterally and inserts it into the arch clamp block. As the wedge block continues to penetrate deeper into the arch clamp block, the arch clamp block is subjected to a downward pulling force. The arch clamp block then clamps and fixes the wire harnesses, preventing them from shifting due to vibration during ultrasonic welding. This ensures the accuracy and stability of the welding, and the ultrasonic welding head can then perform ultrasonic welding between the wire harnesses.

[0009] The beneficial effects of this utility model are as follows: by setting two arch clamping blocks in the base of the device, and then the motor drives the rotating disk to rotate, so that the two wedge blocks move laterally and are inserted into the arch clamping blocks, so that they are subjected to downward pulling force, and then the wire harness is clamped, preventing the wire harness from being misaligned due to vibration during ultrasonic welding, thereby ensuring the accuracy and stability of welding.

[0010] By installing a threaded shaft driven by an electric motor inside the base of the device, the rotation of the threaded shaft causes the linkage plate to rise, and the linkage plate drives the piston to slide in the sliding sleeve through various connecting rods, thereby sucking the air inside the suction cup and adhering it to the worktable, keeping the device stable and preventing it from slipping due to its own vibration.

[0011] Furthermore, a connector seat is bonded to the upper center of the base, and wire harness seats are bonded to the upper end of the base and on both sides of the connector seat. The connector seat and wire harness seat facilitate support during wire harness soldering.

[0012] Furthermore, the rotating disk has an arcuate groove inside, and the end of the slide rod is located inside the arcuate groove. The arcuate groove ensures that the slide rod experiences a radial force from the rotating disk when it rotates.

[0013] Furthermore, the wedge block has an inclined surface at one end near the arch clamping block, and the inclined surface is slidably connected to the inner side of the arch clamping block. The inclined surface on the wedge block allows it to be subjected to a vertical force after being inserted into the arch clamping block.

[0014] Furthermore, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the arch clamping block. The spring provides auxiliary repositioning for the arch clamping block.

[0015] Furthermore, a second motor is fixedly installed at the upper center of the support plate. The output shaft of the second motor passes through the support plate and is connected to the support plate via a bearing. A threaded shaft is fixedly connected to the end of the output shaft of the second motor. The bottom of the threaded shaft is connected to the base via a bearing. A linkage plate is threadedly connected to the outer side of the threaded shaft. A sliding sleeve is fixedly connected to the bottom of the base. A suction cup is fixedly connected to the lower outer side of the sliding sleeve. A piston is slidably connected to the inner side of the sliding sleeve. A connecting rod is fixedly connected to the upper end of the piston. The top of the connecting rod is fixedly connected to the linkage plate. Through the relative threaded movement between the linkage plate and the threaded shaft, the linkage plate moves vertically, thereby pulling the piston to move, causing the suction cup to adhere to the worktable surface, keeping the device stable and preventing it from slipping due to its own vibration.

[0016] Furthermore, a guide post is fixedly connected to the inner bottom of the base. The guide post passes through the linkage plate and is slidably connected to the linkage plate. The top of the guide post is fixedly connected to the support plate. The guide post provides guidance for the lifting and lowering of the linkage plate. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: base 1, mounting base 2, ultrasonic welding head 3, connecting rod 4, connector seat 5, wire harness seat 6, arch clamp block 7, motor one 8, rotating disk 9, fixing sleeve 10, wedge block 11, sliding rod 12, support plate 13, guide rod 14, spring 15, motor two 16, threaded shaft 17, linkage plate 18, guide column 19, sliding sleeve 20, suction cup 21, piston 22.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides an ultrasonic welding device, including a base 1, a mounting seat 2 welded to the upper edge of the base 1, an ultrasonic welding head 3 provided on the front of the mounting seat 2, a connector seat 5 bonded to the upper middle of the base 1, and wire harness seats 6 bonded to the upper end of the base 1 and on both sides of the connector seat 5. The connector seat 5 and wire harness seats 6 facilitate support during wire harness welding. Two arch clamping blocks 7 are slidably connected inside the base 1. A motor 8 is fixedly installed on the inner top of the base 1. A rotating disk 9 is fixedly connected to the end of the output shaft of the motor 8. A fixing sleeve 10 is fixedly connected to the inner top of the base 1 and on both sides of the motor 8. A wedge block 11 is slidably connected inside the fixing sleeve 10. The wedge block 11 is slidably connected to the arch clamping block 7. An inclined surface is provided at one end of the wedge block 11 near the arch clamping block 7, and the inclined surface is slidably connected to the inner side of the arch clamping block 7. By designing the inclined surface of the wedge block 11, after it is inserted into the arch clamp block 7, the arch clamp block 7 can be subjected to a vertical force. A sliding rod 12 is fixedly connected to the bottom of the wedge block 11. The sliding rod 12 passes through the fixing sleeve 10 and is slidably connected to the fixing sleeve 10. The end of the sliding rod 12 passes through the rotating disk 9 and is slidably connected to the rotating disk 9. An arc groove is formed inside the rotating disk 9, and the end of the sliding rod 12 is located inside the arc groove. Due to the arc groove, when the rotating disk 9 rotates, the sliding rod 12 is subjected to a radial force from the rotating disk 9.

[0023] like Figure 2 , Figure 3 As shown, a support plate 13 is fixedly connected to the inner side of the base 1. A guide rod 14 is fixedly connected to the upper end of the support plate 13 and below the arch clamping block 7. The guide rod 14 is slidably connected to the arch clamping block 7, and a spring 15 is sleeved on the outer side of the guide rod 14. One end of the spring 15 is fixedly connected to the support plate 13, and the other end of the spring 15 is fixedly connected to the arch clamping block 7. The spring 15 provides an auxiliary resetting function for the arch clamping block 7.

[0024] like Figure 2 , Figure 3 As shown, a second motor 16 is fixedly installed at the upper middle part of the support plate 13. The output shaft of the second motor 16 passes through the support plate 13 and is connected to the support plate 13 via a bearing. A threaded shaft 17 is fixedly connected to the end of the output shaft of the second motor 16. The bottom of the threaded shaft 17 is connected to the base 1 via a bearing. A linkage plate 18 is threadedly connected to the outer side of the threaded shaft 17. A sliding sleeve 20 is fixedly connected to the bottom of the base 1. A suction cup 21 is fixedly connected to the lower outer part of the sliding sleeve 20. A piston 22 is slidably connected to the inner side of the sliding sleeve 20. A connecting rod 4 is fixedly connected to the upper end of the piston 22. The top of the connecting rod 4 is fixedly connected to the linkage plate 18. Through the relative threaded movement between the linkage plate 18 and the threaded shaft 17, the linkage plate 18 moves vertically, thereby pulling the piston 22 to move, so that the suction cup 21 is adsorbed on the worktable, keeping the device stable and preventing it from slipping due to its own vibration. A guide post 19 is fixedly connected to the bottom inner side of the base 1. The guide post 19 passes through the linkage plate 18 and is slidably connected to the linkage plate 18. The top of the guide post 19 is fixedly connected to the support plate 13. The guide post 19 guides the lifting and lowering of the linkage plate 18.

[0025] The specific implementation process of this utility model is as follows: When in use, first start the second motor 16, the second motor 16 drives the threaded shaft 17 to rotate, and the linkage plate 18 rises under the guidance of the guide column 19. Then the linkage plate 18 pulls the piston 22 through the connecting rod 4, thereby sucking the air inside the suction cup 21 and adsorbing it on the worktable, so that the device remains stable and is not easy to slip due to the vibration of the device itself.

[0026] The two wire harnesses are then threaded onto the inner side of the arch clamp 7 and placed on the wire harness seat 6. The ends of the two wire harnesses are then placed together on the connector seat 5. The motor 8 drives the rotating disk 9 to rotate. As the rotating disk 9 rotates, the sliding rod 12 is subjected to radial thrust from the rotating disk 9. The sliding rod 12 then drives the wedge block 11 to move laterally and insert into the arch clamp 7. As the wedge block 11 continues to penetrate deeper into the arch clamp 7, the arch clamp 7 is subjected to downward pulling force. The arch clamp 7 then clamps and fixes the wire harnesses to prevent them from shifting due to vibration during ultrasonic welding, thus ensuring the accuracy and stability of the welding. The ultrasonic welding head 3 can then perform ultrasonic welding between the wire harnesses.

[0027] This solution involves setting two arch clamping blocks 7 inside the base 1 of the device. Then, the motor 8 drives the rotating disk 9 to rotate, causing the two wedge blocks 11 to move laterally and insert into the arch clamping blocks 7, which then exert a downward pulling force on them. This clamps the wire harness, preventing it from becoming misaligned due to vibration during ultrasonic welding, thereby ensuring the accuracy and stability of the welding.

[0028] By setting a threaded shaft 17 driven by a motor 16 inside the base 1 of the device, the rotation of the threaded shaft 17 will cause the linkage plate 18 to rise. The linkage plate 18 will drive the piston 22 to slide in the sliding sleeve 20 through each connecting rod 4, thereby sucking the air inside the suction cup 21 and adhering it to the worktable, so that the device remains stable and is not easy to slip due to the vibration of the device itself.
