Automatic adhesive pasting device

Abstract

An automatic adhesive pasting device structurally comprises a suction nozzle and a taking platform, wherein the suction nozzle and the taking platform are arranged on a rack, a first tensioning roller is arranged above the taking platform, a second tensioning roller is arranged below the taking platform, adhesive tape is pre-tightened to the taking platform through the first tensioning roller and the second tensioning roller, the taking platform is provided with a taking position, the suction nozzle sucks foam at the taking position under the action of external driving force and is in a static state at the moment, and then the taking platform moves in the direction far from the suction nozzle under the action of the external driving force to make the adhesive tape aligned with the suction nozzle in a suspended state; meanwhile, the second tensioning roller drives the adhesive tape on the back of the taking platform to move along with the taking platform so that the adhesive tape in the suspended state can move towards the back of the taking platform and be stripped off from the foam to be taken. According to the automatic adhesive pasting device, in the taking process, the situation that the foam drives the adhesive tape to move can be effectively prevented, and the adhesive tape is made to keep constant tension all the time; as a result, the production efficiency can be improved, and a good adhesive pasting effect is ensured.

[0002] At present, in the production and processing process of some products, it is necessary to paste foam on some parts of the product to play the role of sealing and damping. In order to facilitate the storage of foam, the foam is pasted on the tape, so that It is necessary to peel off the foam from the tape before sticking the foam to the product. In the traditional technology, the foam is usually separated from the tape by hand to remove the material. During the manual removal process, it is easy for human hands to touch it. to the adhesive layer of the foam, which pollutes the adhesive layer of the foam, reduces the viscosity of the foam, and affects the product quality, and when the foam is manually pasted to the product, the positioning is not accurate, which is likely to cause oblique, The sticking deviation phenomenon further affects the product quality. The most important thing is that the manual operation mode is slow and inefficient, which seriously affects the production efficiency, and the loss of manual labor is large, which increases the production cost.

[0003] In order to solve the above problems, people have designed an automatic glue application device that can automatically apply foam. However, the automatic glue application device in the prior art generally sucks the foam through the suction nozzle, and the suction nozzle moves upward to separate the foam from the adhesive tape. Take the material, and then move the suction nozzle with the foam to the part of the product where the foam is to be pasted to realize the glue application. During the suction nozzle picking process, the foam is separated from the tape due to the upward movement of the suction nozzle after absorbing the foam , and the foam and the tape have a certain bonding force. When the nozzle drives the foam to move upward, the foam will drive the tape to move upward, thereby reducing the tension of the tape, making the tape slack, and even causing The tape is wrinkled or stacked, so that when the suction nozzle picks up the material again, it will not be able to accurately absorb the foam on the tape, which will affect the quality of the glue. At the same time, it is necessary to straighten the tape before retaking the material. thus reducing production efficiency
