Technical Field

[0001] The utility model belongs to the technical field of optical adhesive curing, in particular to an optical adhesive curing device for preventing material overflow and used in production. Background Art

[0002] Optical glue is a special adhesive used to glue transparent optical components, such as lenses, etc. It has the characteristics of colorless transparency, light transmittance of more than 90%, and good bonding strength. In order to achieve the required strength and stability, the optical glue is usually cured during the production process;

[0003] At present, most of the optical adhesive curing equipment in the prior art is carried out through hot air circulation, and the hot air curing methods are divided into upper air outlet and lower air outlet. The wind force of the upper air outlet method is easy to affect the adhesive liquid, causing it to overflow, while the lower air blowing method has a very large blowing range, causing a lot of waste, and it is also impossible to quickly concentrate heat for curing treatment, and the efficiency is low;

[0004] In order to solve the above problems, the present application proposes a curing device for producing optical adhesives that prevents overflow. Utility Model Content

[0005] The utility model aims to provide a curing device for optical adhesive production which can prevent material overflow, and solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a curing device for producing optical adhesives to prevent overflow, comprising a curing machine, adjacent conveyor belts are arranged inside the curing machine, adjacent separation structures of the conveyor belts are used to leave operating space in the middle part, a base for driving the movement of a substrate is arranged above the conveyor belt, the upper end of the base is used to place the substrate and the optical adhesive on the surface of the substrate, limiting belts for blocking the positions of the two ends to prevent heat from overflowing and dispersing are arranged at both ends of the base, stepped transmission shafts for driving the movement of adjacent conveyor belts are arranged at both ends of the curing machine, a hollow plate is arranged above the base, and the mesh holes at both ends of the hollow plate are blocked after the hollow plate is unfolded.

[0008] Furthermore, a hot air blower is installed inside the curing machine, and the hot air blower is located between adjacent conveyor belts. Air ducts connected to the base are respectively installed at both ends of the hot air blower.

[0009] Furthermore, limiting frames for recovering the limiting belts are arranged at both ends of the base, and supporting plates for connecting with the conveyor belts are arranged at the bottoms of both ends of the base.

[0010] Furthermore, the upper end of the base and the lower end of the hollow plate form a limiting cavity for gathering heat, and the limiting cavity gathers heat for quickly heating the substrate to improve the curing efficiency.

[0011] Furthermore, a pull plate is provided at one end of the limiting belt, and the pull plate is used to control the deployment range of the limiting belt.

[0012] Furthermore, a positioning pin is provided at the bottom of the pull plate, and the positioning pin is used to be inserted into the mesh of the hollow plate to fix the limiting belt.

[0013] Furthermore, the bottom of the positioning pin is a conical guiding structure.

[0014] The utility model has the following beneficial effects:

[0015] After the base is replaced by the support to place the substrate, the utility model uses the air duct to send out hot air and gather it inside the limiting cavity, and then heats the substrate to cure the optical glue. Compared with the existing curing method, it can effectively avoid the hot air blowing the glue liquid to cause overflow, and can also prevent the waste caused by heat dispersion, thereby ensuring the efficiency and quality of the optical glue curing operation;

[0016] The utility model can seal the hollow plates at both ends of the hollow plates by unfolding the limiting belt and inserting the positioning pins into the holes of the hollow plates. After this arrangement, heat is gathered at the bottom of the substrate, which can accelerate the curing efficiency and greatly improve the utilization rate of heat, making it easier to use the curing operation and improving the practicability of the equipment. Heat dispersion affects the curing efficiency.

In this embodiment, the installation of the substrate is carried out alternately. When the curing operation is carried out on a substrate at one place, the substrate at another place is installed, thereby forming a cyclic continuous operation.

[0029] Among them, a hot air blower 7 is installed inside the curing machine 1, and the hot air blower 7 is located between adjacent conveyor belts 2. Air ducts 8 connected to the base 3 are respectively installed at both ends of the hot air blower 7.

[0036] An operation flow of the present embodiment is specifically applied as follows: first, the conveyor belt 2 is set to an adjacent separated structure, thereby leaving space for installing the hot air blower 7, and then the substrate is directly placed on the surface of the hollow plate 11, and then the pull plate 13 is pulled to expand the limiting belt 5 to block the mesh holes at both ends of the hollow plate 11, and at the same time, the positioning pin 14 is inserted into the inside of the mesh to form a limit, and finally, the forward and reverse motors are directly used to drive the conveyor belt 2 to operate in a forward and reverse cycle to form an alternating curing operation. At the same time, the base 3 and the hollow plate 11 are used to form a limiting cavity 12 to gather heat inside, and when the two ends of the hollow plate 11 are blocked, the heat is gathered to the substrate, and then the optical adhesive 4 is cured, which can effectively prevent overflow while maximizing the use of heat to prevent heat dispersion from affecting the curing efficiency.
