Abstract

The invention relates to a double sided adhesive tape processing method without adhesive overflow. The process method comprises the following steps: (1) processing a double sided adhesive tape, namely refrigerating for more than 2 hours at a temperature of 0-5 C degree; (2) designing a mold, namely compensating the product dimension and preserving adhesive overflow space; (3) selecting materials; and (4) selecting a device, wherein the sleeve cutting of a circular cutter needs to be controlled within being - / +0.10mm, the circular cutter is high in sleeve cutting precision and stable in performance; the sleeve cutting state during processing needs relatively greatly attention, so that the offsetting of the sleeve cutting can be spotted and the mold can be adjusted in time. According to the double sided adhesive tape processing method, no adhesive overflow occurs during the mold cutting of the double sided adhesive tape; after being delivered, the double sided adhesive tape can be stored at the room temperature at a client; the occurrence that normal surface mounting cannot be carried out due to adhesive overflow during automatic surface mounting in a production line is avoided; the problem of the adhesive overflow of the double sided adhesive tape is ingeniously solved; when the client carries out automatic surface mounting, the problem that a production is boned on a suction nozzle and the surface mounting cannot be carried out due to adhesive overflow never come up again.

Description

technical field

[0001] The invention relates to a zero-spill glue processing method for double-sided adhesive, which is mainly used for processing double-sided glue that is prone to overflow, such as water glue, conductive glue with a thickness of more than 0.1mm, or foam glue, etc., which belongs to double-sided adhesive The technical field of glue processing. Background technique

[0002] The traditional double-sided adhesive processing technology is the reverse cutting process. The double-sided adhesive is frozen before die-cutting, and then the waste rubber of the handle is cut out first. The knife die is punched from the face paper, half-cut to the cover, and then the outer frame of the product is punched. , discharge the relevant waste, and then transfer the product to the material tape, and finally cut the material tape, and the product is rolled. This processing method cannot avoid the problem of glue overflow, and it can be controlled according to 0.1mm of glue ove...

Examples

Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

[0021] The zero-overflow glue processing method of the double-sided adhesive tape of the present invention comprises the following steps:

[0022] (1) Double-sided tape treatment: After the double-sided tape is cut into small rolls, put it into a plastic bag and seal it well, put it in the refrigerator / freezer to freeze, the temperature is 0-5°C, and the refrigeration time is more than 2 hours. The role of the plastic bag is to prevent the end of the double-sided adhesive from freezing. When used at room temperature, the ice melts and beads appear on the end of the film, which affects production and even affects the performance of the adhesive.

[0023] It is a convenient method for water glue that needs to be scraped. Fix the small roll of water glue on the rotating shaft, such as the feeding and unwin...
