Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a height adjusting device. Background Art

[0002] Ultrasonic welding is a critical process in lithium-ion battery production, and its quality significantly impacts the battery's rate capability and internal resistance. In addition to the rational selection of the welding machine and welding head base, the key parameters of ultrasonic welding, such as energy, amplitude, pressure, and weld gap, play a decisive role in determining weld quality.

[0003] Currently, the welding energy, amplitude, and pressure of most ultrasonic welding machines can be fed back online during the welding process, and the welding gap adjustment process is as follows: before welding, set the equipment to manual mode, loosen the limit mechanical knob fixing screw, rotate the limit mechanical knob clockwise or counterclockwise to adjust the descent height of the welding head, tighten the fixing screw after adjustment, click the welding head to lower, and then use a feeler gauge to measure the welding gap. If the welding gap does not meet the requirements, it is necessary to repeat the above operation multiple times until the welding gap meets the requirements. In the above process, the adjustment amount cannot be fed back in real time when rotating the limit mechanical knob, which requires a high level of operating experience of the personnel, and often requires repeated adjustments to reach the required value, which is not conducive to fast and precise adjustment on site.

[0004] In response to the above technical problems, the utility model proposes a height adjustment device, which raises or lowers the second support plate by rotating the screw clockwise or counterclockwise, thereby making the workpiece height adjustable. When used with this height adjustment device, the mechanical knob can reach the adjustment target value at one time, without the need to repeatedly rotate the limit mechanical knob multiple times, thereby achieving fast and precise adjustment.
