The opening groove 8 is connected to the insertion groove 7. The two welding pins 3 are respectively inserted into the two insertion grooves 7. The shape of the area where the opening groove 8 is opened on the solder block 6 is changed by applying an external force to realize the auxiliary pressing and positioning of the solder block 6 relative to the welding pin 3. A plurality of insertion welding holes 9 are arranged on the integrated circuit board 1. The plurality of insertion welding holes 9 are matched with the plurality of welding pins 3 respectively. The design of energy-saving horn capacitors for new energy vehicles forms a combination matrix of multiple horn capacitors. By pre-printing some horn capacitors in the matrix in the integrated circuit board 1 to form a connected circuit, the queue division between the multiple horn capacitors can be achieved. The multiple horn capacitors can be connected in a step-by-step manner, that is, the circuits of different horn capacitors are connected separately, and the charging control of the horn capacitors is formed by alternating on and off of the control circuit. That is, when the external frequency changes at a high speed, the charging of a part of the horn capacitors is realized, and the other part of the horn capacitors are alternately charged and powered for the other part of the horn capacitors during the frequency change process, thereby ensuring the complete charging of a part of the horn capacitors and realizing the charging of the horn capacitors.

The first insertion port 26 and the second insertion port 27 are respectively slidably connected with a first insertion frame 28 and a second insertion frame 29. The first insertion frame 28 and the second insertion frame 29 are both provided with a threaded arc surface 30, and the two threaded arc surfaces 30 are matched with the threaded column 20.

[0036] The integrated circuit board 1, servo motor 21, electric horizontal slide 44, electric vertical slide 45, laser welding head 10 and identification camera 46 in this embodiment are all conventional equipment purchased on the market and well known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of the instruction manual, and will not be described in detail here.

[0037] To sum up, the working principle of the assembly welding device of the energy-saving bull-horn capacitor of new energy vehicles is as follows: when in use, the assembly welding device of the energy-saving bull-horn capacitor of new energy vehicles is first installed in the desired location, and the laser is installed with a laser camera, and the output of the laser in the laser camera is realized through the operation of the laser, and the servo motor 21, the electric horizontal slide 44, the electric vertical slide 45, the laser welding head 10 and the recognition camera 46 are used to complete the installation of the control computer, and the laser is connected to the control computer at the same time. The coordinated control operation of the laser, the servo motor 21, the electric horizontal slide 44, the electric vertical slide 45, the laser welding head 10 and the recognition camera 46 can be set through the control computer. During the operation, the servo motor 21 works to realize the rotation drive of the threaded column 20, and the electric horizontal slide 44 and the electric vertical slide 45 are operated in combination to realize laser welding. The left and right positions and the height of the joint 10 are adjusted, and the identification camera 46 collects the information in the space below the gantry 43 in real time, and transmits the identification information to the control computer in real time, so as to facilitate the control computer to analyze the welding status of the laser welding head 10. Before preparing to weld the welding pin 3 relative to the integrated circuit board 1, first adjust the mounting support limit cover 15 of the clamping positioning frame 12 to face upward, and then open the support limit cover 15 relative to the clamping positioning frame 12, and put the area of ​​the integrated circuit board 1 exposed by the self-support limit cover 15 into the storage slot 14, and then insert the welding pin 3 into the insertion welding hole 9, and make the solder block 6 pass through the integrated circuit board 1 and enter the bottom of the integrated circuit board 1, and repeat the above steps until a plurality of horn capacitors are inserted relative to the corresponding insertion welding holes 9, and slide the support limit cover 15 relative to the clamping positioning frame 12 to close.

[0038] Furthermore, the relative positions of the insertion frame 25 and the upper guide rod frame 18 and the lower guide rod frame 19 are adjusted so that the upper guide rod frame 18 and the lower guide rod frame 19 are both inserted into the insertion frame 25, and during the relative insertion process, the insertion frame 25 is kept at the left end of the clamping positioning frame 12. In this state, due to the linkage transmission effect of the driving shaft 31, the first linkage shaft 32, the second linkage shaft 33, the first linkage rod 34, the second linkage rod 35, the upper offset rod 36, the lower offset rod 37 and the circular shaft 38, the first insertion frame 28 and the second insertion frame 29 will be relatively separated, so the threaded arc surface 30 and the threaded column 20 will be separated. In this state, the rotation of the threaded column 20 will not drive the first insertion frame 28 and the second insertion frame 29 to move. After the upper guide rod frame 18 enters the insertion limit position relative to the insertion frame 25, the clamping positioning frame 12 is rotated and adjusted relative to the insertion frame 25 so that the clamping positioning frame 12 is flipped rightward relative to the insertion frame 25 to enter the position shown in the attached figure. Figure 1 As shown in the state, during this process, the rotation of the driving shaft 31 relative to the insertion frame 25 will cause the upper offset rod 36 and the lower offset rod 37 to form a linkage rotation, and under the transmission action of the first linkage shaft 32 and the second linkage shaft 33, the relative distance between the first insertion frame 28 and the second insertion frame 29 is close, so that the threaded arc surface 30 in the first insertion frame 28 and the threaded arc surface 30 in the second insertion frame 29 will be relatively close and act on the threaded column 20. Thereafter, the threaded column 20 rotates again, and the first insertion frame 28 and the second insertion frame 29 will be driven to move along the threaded column 20, and finally the movement drive of the clamping and positioning frame 12 is achieved, and the structure formed by the integrated circuit board 1 and multiple horn capacitors in the clamping and positioning frame 12 also forms a synchronous displacement. Since the clamping and positioning frame 12 is flipped, the multiple horn capacitors and the integrated circuit board 1 therein are also flipped. The state after flipping is shown in the attached figure. Figure 4 As shown, in this state, when the solder block 6 passes directly under the gantry 43, the recognition camera 46 recognizes it and forms a heating operation through the laser beam guided and output by the laser welding head 10, so that the solder block 6 on the soldering pin 3 is heated and forms a flow under the action of its own gravity to form contact with the inserted welding hole 9, and finally achieves the welding operation of the soldering pin 3 relative to the integrated circuit board 1. After the welding is completed, when the first insertion frame 28 and the second insertion frame 29 move synchronously to the rear end of the threaded column 20, the insertion frame 25 will be separated from the support and guidance formed by the upper guide rod frame 18 and the lower guide rod frame 19, and finally fall on the outer ramp plate 22, and enter the rotary guide box 23 after being guided by the outer ramp plate 22, and finally approach the clamping and positioning frame 12 again relative to the upper guide rod frame 18 and the lower guide rod frame 19. The placement station, so that the operator can take out the energy-saving horn capacitor for new energy vehicles in the clamping and positioning frame 12 after the welding is completed, and it is also convenient to reuse the clamping and positioning frame 12 after the cycle is completed.
