N95 mask double-station strap spot welding machine

Abstract

The invention relates to an N95 mask double-station strap spot welding machine, and belongs to the field of N95 mask strap spot welding machines. The device comprises a workbench, a support and a positioning device which are fixedly connected are arranged on the workbench; a welding device and a movable strap clamping device are arranged on the support, and a strap pulling device connected with the workbench is arranged below the strap clamping device; and the positioning device comprises a first sliding guide rail fixed to the workbench, a first sliding block which is slidably connected is arranged on the first sliding guide rail, a supporting frame is arranged on the first sliding block, two rotating air cylinders which are parallel are arranged on the supporting frame, and positioning tools which are fixedly connected are arranged on the rotating air cylinders. Compared with the prior art, the machine has the beneficial effects that firstly, two welding stations are arranged on onepositioning device, that is, two welding stations are arranged on one strap welding machine, and only one person is needed for one welding station, so that the equipment cost and the labor cost of anenterprise are reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to a double-station ear strap spot welding machine for an N95 mask, which belongs to the field of N95 mask ear strap spot welding machines. Background technique [0002] First, the single-station welding earphones on the market need to manually rotate the mask and then weld, but the manual rotation not only makes the welding position of the ear straps not standard enough, but also the labor intensity of the workers is high, and the efficiency of the workers will decrease after working for a long time; second, The distance between the ear belt transmission wheel and the roller in the upper right corner is not easy to control. If the distance is too close, the ear belt may be stuck and cannot move forward. If the distance is too far, the ear belt will go off track, which will affect the subsequent steps. Third, the market The above equipment is used in the automatic assembly line and is basically a single station, so the labor cost ...

Problems solved by technology

[0002] First, the single-station welding earphones on the market need to manually rotate the mask and then weld, but the manual rotation not only makes the welding position of the ear straps not standard enough, but also the labor intensity of the workers is high, and the efficiency of the workers will decrease after working for a long time; second, The distance between the ear belt transmission wheel and the roller in the upper right corner is not easy to control. If the distance is too close, the ear belt may be stuck and unable to move forward. If the distance is too far, the ear belt will go off track, which will affect the progress of the next steps. Third, the market The above equipment is used in the automatic assembly line and is basically a single station, so the labor cost and equipment cost are relatively high, and the work efficiency is low; Fourth, when the vertical pneumatic gripper clamps the ear strap, the ear strap is easy to twist and break Therefore, there is an urgent need for a new type of N95 mask double-station earband spot welding machine on the market.
