Description

Double-station conductive adhesive tape slitter
Technical Field
The invention relates to rubber processing equipment, in particular to a double-station conductive adhesive tape slitter.
Background
The conductive adhesive tape is commonly called as a zebra adhesive tape and is formed by alternately layering conductive silica gel and insulating silica gel and vulcanizing the same. The conductive adhesive tape has stable and reliable performance, is simple and convenient and efficient to produce and assemble, and is widely used for connecting liquid crystal displays of products such as game machines, telephones, electronic watches, calculators, meters and the like with circuit boards.
The manufacture of the conductive adhesive tape is not separated from the strip cutting step, namely, a piece of film with the length and the width being equal to the size of A3 paper (420 mm multiplied by 297 mm) and the thickness being between 0.5 and 8mm is cut into strips. The length of the adhesive tape is between 10 and 70mm, and the width is between 2 and 10 mm. Meanwhile, the requirement on the precision of the adhesive tape is higher: the length and width dimension precision is +/-0.02 mm, and the verticality of the long side and the wide side is +/-0.1 degree.
At present, a block-shaped conductive film is cut into strips, and the main method is as follows:
1. roll cutting, i.e. pressing a block of film onto a plate in advance, and then rolling with a hob.
2. Similar to a plate shearing machine type up-down punching type cutting method.
The roll cutting method is basically eliminated by industry due to the poor precision and low efficiency of the cut adhesive tape. The punching cutting method is basically adopted at present.
The current problems of stamping type cutting methods are:
1. the cutting precision can not reach the precision required by industrial automatic production. The punching cutting method cuts the film in the following steps: firstly, fixing a film on a cutting machine for cutting in the length direction; and then the film is taken down and then transferred to another cutting machine for cutting in the width direction. In the cutting mode, the film needs to be clamped for the second time, and positioning errors are easy to generate in the second clamping, so that the cut adhesive tape is not rectangular but parallelogram required by production. Namely, the length and width dimension out-of-tolerance and the length and width verticality out-of-tolerance exist. To reduce this error, adjustments to the equipment are often made during production. The need to adjust equipment and transfer film between two machines severely affects the quality and efficiency of production.
2. The strip must be manually loosened during cutting. If the adhesive tapes are not loosened, the adhesive tapes can be mutually extruded, so that the adhesive tapes are mutually overlapped, and even the phenomenon of strip jumping can occur, so that the strip cutting work can not be normally performed.
3. Safety problem: when the strip is cut, the cut adhesive tape needs to be loosened (if the adhesive tape is not loosened, the adhesive tapes are mutually extruded to cause stacking, the cutting precision is affected if the adhesive tapes are light, and the strip cutting work cannot be continued if the adhesive tape is serious). The existing method is as follows: the manual scarfing is performed while the strip is cut, so that the finger of a worker can be cut to cause safety accidents when the worker is left without attention. In addition, the up-and-down cutting movement of the cutter is driven by an air cylinder, and the piston movement stroke of the air cylinder is difficult to accurately control due to the large air compressibility. When the occasional electric protection fault occurs, the limit of the cutter lifting stroke of the cutter fails, and the cutter is lifted too high; because of the mechanical raking action, the fingers of workers can easily extend below the cutters, and safety production accidents are easily caused. Therefore, the manual raking action is canceled, and the lifting height of the blade is strictly controlled, so that the production safety of the conductive adhesive slitting workers is ensured.
