The washing machine tub lid is a core sealing component
of the inner tub, and its welding quality directly determines the sealing performance and service life of the washing machine. Washing machine tubs are produced in large volumes, requiring high welding efficiency. Washing machine tubes are often exposed to vibration and humid environments over long periods, which imposes extremely high requirements on the strength and air-tightness of the welded joint.
Traditional welding processes for washing machine tub lids are highly dependent on manual labor. The production cycle time is limited by manual speed, and the positioning accuracy of lids loading varies from person to person, making it difficult to ensure welding consistency.
Considering above condition, MP Sonic designed fully automatic spin equipment specially for washing machine tube lids welding.
I. Material: Normally PP, PE
II. Requirment: A. Air-tightness of welding; B. Neat surface after welding at joining area.
III. Main Function:
A. Servo-driven spin welding: welding parameters are adjustable, offering strong welding capability, high precision;
B. Automatic loading and unloading: communicates with a robotic arm for automatic feeding, positioning, and unloading of washing machine tubs;
C. Automatic feeding: tub lids are automatically sorted and conveyed by a vibratory bowl feeder, eliminating manual loading;
D. Leak testing: automatically air-tightness testing is performed after welding;
E. Automatic positioning: the tub automatically finds and accurately positions itself at the working station upon entry, without manual position adjustment;
F. Flexible changeover: supports quick switching between two or more washing machine tub models without changing fixtures;
G. Safety protection: Independant logistic controlled optical fence and door switch. Using protective mesh guard to ensure personnel safety.
IV. Benefit:
A. High welding efficiency;
B. Fully automatic operation, labor free, reduced cost;
C. Stability in welding performance and high welding qualification rate;
D. Strong welding consistency.
