Description

Technical Field

[0001] The invention relates to the technical field of automobile plastic ultrasonic welding, in particular to an automobile component ultrasonic welding assembly. Background Art

[0002] The working principle of ultrasonic plastic workpiece welding technology is as follows: the generator generates high-voltage and high-frequency signals, which are converted into high-frequency mechanical vibrations through the transducer system and applied to the plastic workpiece. The temperature of the workpiece interface is increased through the friction between the workpiece surface and the internal molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface quickly melts and then fills the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure, thereby achieving the welding purpose.

[0003] Since it is impossible to achieve 100% energy conversion efficiency during the welding process, part of the lost energy should be converted into heat; when the temperature rises, the parameters of the sensor will change and gradually deviate from the optimal matching state; more seriously, if the temperature is too high, the performance of the piezoelectric ceramic wafer will decline; in this way, the working conditions of the sensor become worse, the heating speed becomes faster, and a vicious circle is formed; therefore, good cooling conditions must be provided for the sensor;

[0004] In addition, the inverter and drive power supply did not reach the optimal working state during the operation and use of the machine, causing very large heat and uncontrollable serious consequences; when the temperature is too high, the mechanical strength of aluminum will drop sharply; under the action of such high power, cracks in the ultrasonic transducer are inevitable.

[0005] Patent No. CN202011463066.6 discloses an ultrasonic plastic welding machine that can realize continuous welding, which welds non-woven fabrics and plastic parts by using the ultrasonic plastic welding machine that can realize continuous welding, places the non-woven fabric between two adjacent pallets, and fits the two sides of the non-woven fabric product to the two adjacent pallets. The plastic parts are clamped into the two sides of the limit plate for fixation, and the conveyor belt delivers the fixed workpiece to be processed to the bottom of the welding head. Ultrasonic welding is used for welding. The operator only needs to stand at a fixed workstation to place the workpiece to be processed. The ultrasonic plastic welding machine that can realize continuous welding can weld continuously, and the alternating process of manual and mechanical work is changed to simultaneous operation, thereby improving production efficiency. However, the device has the following problems: First, the service life of the ultrasonic welding machine is short, the temperature cannot be controlled, and it cannot cope with emergencies caused by overheating. Secondly, the welding part is prone to distortion, warping and deformation, and the internal stress of the material cannot be eliminated. Summary of the invention

[0006] The purpose of the present invention is to address the deficiencies of the prior art. By providing a feeding box and a temperature control box of an upper component feeding mechanism, the work that needs to be welded is kept at a temperature below 60°C, thereby eliminating the internal stress of the plastic component and reducing the distortion and warping of the welding position. By using a water outlet pipe, a cooling water pipe and other circulating cooling water pipelines, not only the temperature of the automobile parts can be controlled, but also the ultrasonic welding machine can be cooled and the conveying mechanism can be driven to operate, thereby solving the technical problems of the prior art that the ultrasonic welding machine has a short service life, the welding part cannot eliminate stress, and the energy consumption is high.

At normal temperature, the blades are straight; at high temperature, the blades can bend to one side because the internal energy of the hot water is converted into mechanical energy. When the blades of the waterwheel components are immersed in hot water, the temperature rises and the blades quickly bend to one side, giving the hot water a force. Since the action of force is mutual, the hot water will exert a reaction force on the blades to make the waterwheel components rotate. When the hot water pushes the blades to move and perform work, the internal energy of the water is consumed, and the temperature of the water will gradually decrease. Then the cooled water enters the cooling box to cool the ultrasonic welding machine, thereby extending the service life of the ultrasonic wave.

[0020] (3) In the present invention, a clamping and feeding mechanism and a second clamping and feeding mechanism are provided to clamp and feed automobile parts and place them on a welding mold table.

A telescopic rod 341 is provided at the lower end of the cylinder 381. The lower end of the telescopic rod 341 is rotatably connected to the main control board 383. The lower end of the main control board 383 is fixedly connected to a track plate 385. Two identical clamping cylinders 386 are fixedly connected to the left and right sides of the lower end of the track plate 385.

[0039] A motor 382 is provided at the upper end of the cylinder 381.

[0041] The blades 43 are made of high molecular polymer materials and can bend to one side at high temperatures. As the temperature rises, the blades 43 bend rapidly to one side, giving the hot water a force. Since the force is mutual, the hot water will exert a reaction force on the blades 43, causing the waterwheel component 42 to rotate. When the blades 43 rotate out of the water, the temperature drops, and the blades 43 return to a straight state. This process is continuously carried out, which will cause the waterwheel component 42 to rotate continuously, thereby realizing the transportation function of the entire transportation mechanism 4.

The No. 2 clamping feeding mechanism 7 only needs one clamping cylinder 386 and one clamping hand assembly to clamp the upper component and place it accurately. It is reasonably designed into a clamping cylinder 386 to ensure higher precision and low equipment cost.

[0044] Working process: first, put the automobile parts to be welded into the loading box 1 and the double-layer heating loading box 61, and then use the heating layer 62 and the heating wire layer 101 to heat the loading box 1 and the double-layer heating loading box 61, so that the placed automobile parts are kept below the temperature of thermal deformation, and then pass cooling water into the main water inlet pipe 65, and the cooling water enters the temperature control layer 63 from the main water inlet pipe 65, and then enters the transfer water pipe 64 through the temperature control layer 63, and then enters the cooling water flow layer 102 of the loading box 1, and then enters the sealing round cover 46 of the conveying mechanism 4, and works on the waterwheel component 42, so that the movable rotating shaft 44 can rotate normally, so that the welding mold table 5 can be intelligently and automatically transmitted, the cooling water has a higher temperature because it has passed through the temperature control layer 63 and the cooling water flow layer 102, and then the temperature is reduced after the internal energy of the hot water is consumed by the waterwheel component 42 as mechanical energy, and then flows through the cooling box 81 to cool down the ultrasonic welding machine 8, thereby extending the service life of the ultrasonic welding machine 8;

[0045] The waterwheel component 42 rotates to transport the welding mold table 5. The welding mold table 5 is connected to the closed belt by magnets and magnetic blocks, which is convenient for fixing the position and conveying. Moreover, when it is necessary to replace the welding mold table 5 of different models, it can also be disassembled and replaced, and has a wide range of applications. The lower ends of the loading box 1 and the double-layer heating loading box 61 are both provided with a vibrator, and the vibration causes the automobile parts to enter the spiral platform, and then enter the loading channel 12, so that the loading table 13 uses the clamping loading mechanism 3 to clamp and load. When the welding mold table 5 enters the lower end of the ultrasonic welding machine, ultrasonic welding is performed. After welding is completed, it reaches the right end of the conveying mechanism 4 to wait for the staff to unload the welding mold table 5, and then cool it to room temperature, and the mold is welded into shape;

[0046] The entire assembly has a high degree of automation. By setting up a temperature control box for the feeding box and the upper component feeding mechanism, the work that needs to be welded is kept at a temperature below 60°C, thereby eliminating the internal stress of the plastic parts and reducing the distortion and warping of the welding position. The use of outlet pipes, cooling water pipes and other circulating cooling water pipelines can not only achieve temperature control of automotive parts, but also cool the ultrasonic welding machine and drive the transportation mechanism to operate. It is simple and efficient, has good practical effects, saves energy, makes rational use of resources, and extends the service life of the machine.
