[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] This utility model provides, for example Figure 1-Figure 5 An ultrasonic welding device is shown, comprising: an operating table 1, an ultrasonic welding head 3, and a cooling fan 6. The ultrasonic welding head 3 is mounted on one side of the upper end of the operating table 1 via a support column 2. The support column 2 is L-shaped, with one end fixed to the upper end of the operating table 1 and the other end located at the upper end of the operating table 1 and fixedly connected to the ultrasonic welding head 3. An air outlet 4 is provided on one side of the upper end of the operating table 1, and the cooling fan 6 is fixedly installed at the lower end of the air outlet 4. When the cooling fan 6 is turned on, it can blow air towards the upper end of the air outlet 4 to quickly cool the welded plastic plate.

[0028] The upper end of the operating table 1 is slidably connected to a base plate 17 via a driving component. The base plate 17 has several through holes and is U-shaped. A fixing block 9 is slidably connected to one side of the upper end of the base plate 17, and a fixing block 9 is fixedly installed on the other side. The driving component includes a strip hole 7, two slide grooves 8, a driving plate 19, and a fixing plate 21. The strip hole 7 is located at the center of one end of the operating table 1. The slide grooves 8 are located on the front and rear sides of the upper end of the operating table 1 and are located on the front and rear sides of the strip hole 7. A slider 18 is slidably connected in the slide groove 8. The upper end of the slider 18 extends out of the slide groove 8 and is fixedly installed on the lower side of the base plate 17. The upper end of the driving plate 19 is fixedly installed on the lower side of the base plate 17. The other end of the driving plate 19 slides through the strip hole 7 and is fixedly installed with a threaded sleeve 20.

[0029] Two fixing plates 21 are provided, which are fixedly installed at the lower end of the operating table 1 respectively. A threaded rod 23 is rotatably connected between the two fixing plates 21. A threaded sleeve 20 is threadedly connected to the outer wall of the threaded rod 23. A motor 22 is fixedly installed on the side wall of one of the fixing plates 21. The output end of the motor 22 is fixedly connected to one end of the threaded rod 23 through a coupling. The motor 22 is a servo motor, which can drive the threaded rod 23 to rotate in both directions. By starting the motor 22, the threaded rod 23 is driven to rotate. The threaded rod 23 drives the threaded sleeve 20, which in turn drives the drive plate 19 to move the base plate 17 on the operating table 1. The base plate 17 can be moved to the upper end of the air outlet 4.

[0030] One of the fixing blocks 9 has a limiting plate 12 fixedly installed on the inner side of one end. The other end of the limiting plate 12 slides through the side wall of the other fixing block 9. A sliding hole 10 is provided on the side wall of one of the fixing blocks 9. One end of the limiting plate 12 slides through the sliding hole 10. An electric push rod 15 is fixedly installed between the two fixing blocks 9. Ear plates 13 are fixedly installed on both the left and right ends of the electric push rod 15. One end of the ear plate 13 is fixedly installed on the outer wall of the fixing block 9. By starting the electric push rod 15, one fixing block 9 can be moved, thereby changing the distance between the two fixing blocks 9, which is convenient for clamping plastic plates of different lengths.

[0031] The other ends of the two fixing blocks 9 are slidably connected to the limiting plate 27 via the electric push rod 2 16. The outer ends of the two fixing blocks 9 are provided with mounting grooves 11. The left and right ends of the limiting plate 27 pass through the mounting grooves 11. One end of the electric push rod 2 16 is fixedly installed on the inner wall of one side of the mounting groove 11, and the other end is fixedly connected to the side wall of the limiting plate 27. By activating the electric push rod 2 16, the limiting plate 27 can be driven to slide in the mounting groove 11, changing the distance between the limiting plate 1 12 and the limiting plate 27, so as to clamp plastic plates of different widths.

[0032] Specifically, pressure sensors can be fixedly installed on the inner walls of the two fixing blocks 9, the first limiting plate 12, and the second limiting plate 27. The sensors are electrically connected to the controller 26. The pressure value received by the pressure sensor is input into the controller 26 in advance. When the pressure detected by the pressure sensor is greater than the preset value, the controller 26 stops the operation of the first electric push rod 15 and the second electric push rod 16. The clamping force of the two fixing blocks 9 on the plastic plate and the clamping force of the first limiting plate 12 and the second limiting plate 27 on the plastic plate can be detected by the pressure sensor. This avoids the plastic plate to be welded being damaged by excessive clamping force, and at the same time realizes automatic clamping and improves clamping efficiency.

[0033] A controller 26 is fixedly installed on the outer wall of the support column 2. The controller 26 is electrically connected to the motor 22, electric push rod 15, electric push rod 26, electric push rod 3 and ultrasonic welding head 3 respectively.

[0034] A lifting component is provided between the two fixing blocks 9, the first limiting plate 12, and the second limiting plate 27. The lifting component includes a lifting plate 24 and an electric push rod 25. Several through holes are evenly distributed on the side wall of the lifting plate 24. The electric push rod 25 is fixedly installed on the inner end of the base plate 17, and the upper end of the electric push rod 25 is fixedly installed on the lower end of the lifting plate 24. The lifting plate 24 is located at the lower end of the fixing blocks 9. More specifically, when two plastic plates need to be welded together, the two plastic plates are placed on the upper end of the lifting plate 24, and the electric push rod is activated. Rod 15 and electric push rod 26 clamp and fix the two plastic plates, and then weld them together using ultrasonic welding head 3. After welding, the two welded plastic plates are moved to the upper end of the air outlet 4 by the drive component for air cooling. After cooling is completed, controller 26 controls electric push rod 15 and electric push rod 26 to drive the fixing block 9, limit plate 12 and limit plate 27 away from each other, and then drives electric push rod 325 to drive the lifting plate 24 to move the welded plastic plates up, so that the plastic plates can be removed.

[0035] like Figure 4 and Figure 5 As shown, in some embodiments, ear plates 13 are fixedly installed on the outer walls of the front and rear ends on both sides of each fixed block 9. A telescopic tube 14 is fixedly installed between the two ear plates 13 on one side. More specifically, when the electric push rod 15 is started, it drives a fixed block 9 to slide in the sliding hole 10. At the same time, one end of the telescopic tube 14 slides inside the other end, which plays a role in guiding and limiting the fixed block 9, making its movement more stable.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, a mesh plate 5 is fixedly installed inside the air outlet 4. More specifically, rubber sleeves are fixedly installed on the outer walls of all four ends of the mesh plate 5. The mesh plate 5 is inserted into the air outlet 4 by squeezing the rubber sleeves to block the air outlet 4 and prevent foreign objects from falling into the cooling fan 6.

[0037] Working principle:

[0038] Step 1: When two plastic plates need to be welded together, place the two plastic plates on the upper end of the lifting plate 24, and start the electric push rod 15 and electric push rod 26 to clamp and fix the two plastic plates, and then weld them through the ultrasonic welding head 3.

[0039] Step 2: After welding is completed, the two welded plastic plates are moved to the upper part of the air outlet 4 by the drive component for air cooling. After cooling is completed, the controller 26 controls the electric push rod 15 and the electric push rod 26 to drive the fixing block 9, the limit plate 12 and the limit plate 27 to move away from each other. Then, the electric push rod 325 drives the lifting plate 24 to move the welded plastic plate up, so that the plastic plate can be removed. After the plastic plate is removed, the drive component drives the base plate 17 to reset.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
