Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of bulletproof helmet processing, and in particular, to an automatic production line for processing bulletproof helmets. Background Art

[0002] Bulletproof helmets are major military products used to protect the user's head. The main materials of bulletproof helmets are ultra-high molecular weight polyethylene fiber and aromatic polyamide. Ultra-high molecular weight polyethylene fiber is used to produce the main body of the bulletproof helmet, and multiple layers of aramid fiber are added to the helmet main body in sequence to improve the protective effect of the bulletproof helmet on the user's head.

[0003] In the production process of bulletproof helmets, laser die-cutting machines and hot pressing equipment are used. The laser die-cutting machine will first be used to die-cut a whole piece of aramid fiber in sequence, and the aramid fiber will be die-cut into different shapes. The formed helmet body will then be placed on the lower mold of the hot pressing equipment. The staff will then place each layer of aramid fiber on the helmet body, start the hot pressing equipment to drive the upper mold down, and hot-press the aramid fiber and the helmet body together. Using the above method, multiple layers of aramid fiber are processed into the helmet body in sequence to complete the production and manufacturing of the bulletproof helmet.

[0004] Because during the production process of bulletproof helmets, the appearance of each layer of aramid fiber placed on the helmet body is different, so in the process of placing the aramid fiber layer on the helmet body, it is necessary to strictly ensure that the aramid fiber layer is placed in place. The existing technology uses a pneumatic clamp to grab the die-cut aramid fiber layer, and adopts the principle of vacuum adsorption to grab the aramid fiber layer. However, when using the pneumatic clamp to grab the aramid fiber layer, the aramid fiber layer needs to be kept absolutely flat so that it can be effectively adsorbed. In the process of placing the aramid fiber layer on the helmet body, because the aramid fiber layer is a plane during the adsorption process, but the helmet body is a curved surface, when the pneumatic clamp stops adsorbing the aramid fiber layer, the aramid fiber will shift in the process of falling onto the helmet body. Summary of the Invention

[0005] To overcome the above-mentioned defects, an embodiment of the present invention provides an automatic production line for processing bulletproof helmets, which is used to solve the technical problem in the related art that aramid fibers are easily displaced when the die-cut aramid fiber layer is moved onto the helmet body during the production process of bulletproof helmets.
