Description

Technical Field

[0001] The invention relates to the technical field of mask manufacturing, and in particular to a mask ear strap punching device and a preparation method thereof. Background Art

[0002] In traditional mask processing, the welding of ear straps is done by manual spot welding machines. Workers are required to cut the ear straps first, and then place the ear straps and masks under the welding head of the spot welding machine, and control the welding head for spot welding. Manual processing is slow and the quality cannot be guaranteed. Later, a fully automatic cup-shaped mask strapping machine appeared. It controls four spot welding machines to spot weld above the four welding points of the mask. Each spot welding machine is equipped with a tape taking device and a cutting device. The four welding points are carried out simultaneously, and the cutting and feeding of the ear straps are all completed by fully automatic machinery, which increases the efficiency by 5 times. The spot welding performed by the automatic positioning device is more accurate than the manual positioning of workers, and the processing quality is higher. However, since there are four spot welding machines, and each spot welding machine is equipped with tape taking, cutting and other devices, the equipment is too large and the cost is high. In addition, the connection effect of spot welding is not very strong and easy to disconnect. Summary of the invention
