The top end of the motor drive shaft 55 is connected to the base frame 56, and a stabilizing block 57 is provided on the surface of the base frame 56. The stabilizing block 57 is connected to the movable block 54 by adding two sets of electric telescopic rods 59. The installation slot 510 is provided at the bottom of the first fixed block 51, and the installation slot 510 corresponds to the positions of the movable block 54 and the stabilizing block 57.

[0020] As the first embodiment of the utility model: the first fixed block 51 is composed of two completely equally divided fixed blocks. The design sets up two identical fixed blocks to form the first fixed block 51, which helps to meet the needs of pressure welding circuit boards of different sizes. The electric telescopic rod 59 is fixed inside the stabilizing block 57 as a whole by opening a card slot, and the top of the electric telescopic rod 59 is welded to the movable block 54. The design uses the electric telescopic rod 59 to help the movable block 54 stretch, thereby adjusting the size of the positioning groove 52 to better adapt to the circuit board pressure welding. The top of the motor drive shaft 55 is welded on the base frame 56, and the height of the motor drive shaft 55 meets the height of the second fixed block 53. The design adds the motor drive shaft 55 in the second fixed block 53. 5.

Of course, before pressure welding, the staff will place the circuit board with the LED wick into the fixed assembly 5 according to the needs of the LED unit. The motor drive shaft 55 is controlled and driven by the connecting wire 6, and will rotate slowly to adjust the direction of the first fixed block 51. If the size of the circuit board with the LED wick does not meet the requirements and cannot be placed in the positioning groove 52, it is necessary to start the electric telescopic rod 59. Through the action of the electric telescopic rod 59, the movable block 54 is moved, so that the first fixed block 51 connected to the movable block 54 through the installation slot 510 will be unfolded, and the positioning groove 52 will also become larger to meet the needs of circuit boards of different sizes. Then, the compressor head 7 pressure welds the circuit board to complete the ultrasonic pressure welding of the LED lamp.
