Description

Technical Field

[0001] The utility model relates to a film tearing device, in particular to a high-speed film tearing device for double-sided adhesive materials. Background Art

[0002] Double-sided adhesive material is a roll of adhesive tape made by evenly coating an elastomeric pressure-sensitive adhesive or a resin-based pressure-sensitive adhesive on a paper, cloth, or plastic film substrate. It consists of three parts: substrate, adhesive, and release paper (film). Double-sided tape can be divided into solvent-based adhesive tape (oil-based double-sided tape), emulsion-based adhesive tape (water-based double-sided tape), hot-melt adhesive tape, calendered adhesive tape, and reactive adhesive tape based on the adhesive properties. Double-sided tape is used in the assembly of electronic components to achieve waterproof and dustproof effects. It is wrapped in two layers of protective film, which must be removed before assembly. Double-sided tape is coated in a certain shape with narrow edges. After the protective film is removed, the equipment automatically adjusts the position of the double-sided tape and the product for bonding. The effectiveness of tearing off the protective film determines the quality of the double-sided tape bonding.

[0003] In the prior art, due to the particularity of double-sided tape, especially in the dust-free workshops of some electronic equipment and on some production lines where double-sided tape products are required, employees need to wear dust-proof clothing and dust-proof gloves. Since the isolation film is very thin, it is very difficult for employees wearing dust-proof gloves to manually tear off the isolation film, resulting in low work efficiency, high labor costs, and time-consuming and labor-intensive work that affects work efficiency. Manual tearing of the film also increases the damage rate of the double-sided tape block when it is removed. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a high-speed film tearing device for double-sided adhesive materials, which effectively solves the problem in the prior art that due to the particularity of double-sided adhesive, especially in the dust-free workshops of some electronic equipment, on some production lines that need to stick double-sided adhesive products, employees need to wear dust-proof clothing and dust-proof gloves, etc., and since the thickness of the isolation film is very thin, it is very difficult for employees wearing dust-proof gloves to manually tear the isolation film, resulting in low work efficiency, high labor costs, and time-consuming and labor-intensive work that affects work efficiency. Manual film tearing also has the problem of increased damage rate of removed double-sided adhesive blocks.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes a base arranged at the bottom, a first bracket installed on the top of one end of the base and a discharge roller installed on the first bracket, and also includes a rotating shaft, a limit plate, a film tearing assembly, a second bracket, a receiving roller and a baffle, a rotating shaft is inserted through the middle of the discharge roller, a limit plate is installed at one end of the rotating shaft, a film tearing assembly is installed on the base on one side of the first bracket, a second bracket is installed between the film tearing assembly and the first bracket, and a receiving roller is installed on the top and bottom of the second bracket;

[0006] The film tearing assembly includes a third bracket, a disc, a suction cup, a drive motor, an air compressor and an air pipe. The third bracket is fixed on the base. The disc is symmetrically installed on the inner side of the third bracket. Several suction cups are installed on the edge of the disc. The drive motor is installed at one end of the disc. The air compressor is installed on one side of the first bracket, and the air outlet of the air compressor is connected to the air pipe.

[0007] Preferably, at least three suction cups are axially installed.

[0008] Preferably, a driving motor is installed at one end of the receiving roller.

[0010] Preferably, the limiting plate is connected to the rotating shaft via bolts or threads.

[0011] Preferably, a baffle is installed at one end of the base.

[0012] Beneficial effects: When the utility model is used, the unwinding roller that needs to be used for film tearing is placed on the rotating shaft, and the upper limit disc is installed. Then, the rotating shaft is placed in the groove corresponding to the first bracket, and the film tearing operation can be performed. When tearing the film, the drive motor is activated, and the drive motor drives the disc and the suction cup to rotate. When the suction cup on the disc contacts the film, the air compressor drives the suction cup to adsorb the upper and lower films. Then, the above steps are followed to rotate and adsorb. When the suction cup rotates to the right side of the third bracket, the suction cup is released. At this time, the take-up roller rotates to rewind the film, and the high-speed film tearing of the double-sided tape can be completed. The operation is simple and convenient.
