Problems solved by technology

This method includes the following disadvantages: the high polymer acrylic board is expensive, and it is limited to small characters of about 10cm, and the increase in the number of characters will cause joint costs
Grinding and spraying paint is very polluting to the environment
After injecting resin on the surface, there is a problem with the LED on the inner surface, which is inconvenient to repair

Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0024] A production process of a luminescent sign based on engraved AB glue injection molding surround comprises the following steps:

[0025] Step 1: Grind and sand the surface of the acrylic board and the PVC foam board that need to be bonded, and then pour a thin layer of AB glue on the sanded surface. After curing to thicken for 2 hours, glue the two boards together Together, after the AB glue is fully cured after 8 hours, a layer of transparent film is attached to the bottom to prevent the epoxy resin from seeping out.

[0026] Step 2: Carve the groove on the engraving machine. Before carving the groove, do the alignment point. The alignment point is to carve 4 small holes at different positions on the board, and then save the file. Next time when engraving the AB glue of the groove, firs...

Abstract

The invention relates to the field of luminous sign advertisements, in particular to a luminous sign production technology based on AB glue carving and surrounding edge injection molding. The technology includes the following steps that firstly, an acrylic board and other cheap boards such as a PVC foam board are synthesized; secondly, a hollowed groove is carved; thirdly, vacuum defoaming is carried out, and AB glue is injected into the hollowed groove till the hollowed groove is full; fourthly, AB glue carving is carried out; fifthly, the PVC foam board is hollowed out, an original line is marked, and a sign is carved. According to the technology, a common machine is used for carving in the whole manufacturing process and ensures working precision; the adopted boards are good in heat dissipation, and the service life of LEDs can be prolonged to the maximum.

Description

technical field [0001] The invention relates to the field of luminous signs and advertisements, in particular to a production process of luminous signs based on engraving AB glue injection molding surrounds. Background technique [0002] Advertising signs can be defined as identification devices that can be installed in different time and space environments by standing, hanging, hanging, sticking, etc., have certain production standards and various textures, and express orientation functions or information functions through text and graphics. The specific manifestations of signs are various: there are texts, graphics, sounds, images, optoelectronics, etc., through wood, metal, plastic, rubber, textiles, paper products, liquid crystal displays and other media to achieve the purpose of expression. [0003] There are currently several ways to identify advertisements: [0004] Use digital plasma cutting machine to make advertising logo craft. This process first cuts out the st...
