Full-automatic adhesive pouring machine with double vacuum tanks

Abstract

The invention discloses a full-automatic adhesive pouring machine with double vacuum tanks. The full-automatic adhesive pouring machine comprises a vacuum adhesive pouring tank, a product conveyor line and the small vacuum tank. The small vacuum tank is connected with the vacuum adhesive pouring tank and is communicated with an inner cavity of the vacuum adhesive pouring tank via a first opening,and the first opening can be sealed or opened by a plate; the capacity of an inner cavity of the small vacuum tank is larger than the volume of each product and is smaller than the capacity of the inner cavity of the vacuum adhesive pouring tank, and second openings are further formed in a bottom plate; the product conveyor line is positioned below the vacuum adhesive pouring tank and is providedwith product carrying tables, trays and a lifting mechanism, and the trays can be driven to be lifted; the shapes of the trays correspond to those of the second openings, the products can be conveyedinto the small vacuum tank when the trays are elevated, the second openings are simultaneously closed, accordingly, the small vacuum tank can be sealed, and vacuum pumping treatment can be carried out. The full-automatic adhesive pouring machine has the advantages that the large vacuum tank and the small vacuum tank are designed, accordingly, the vacuum pumping time can be shortened to a great extent, the work efficiency can be improved, and power requirements on vacuum pumps can be lowered; the products can be stably and reliably transported, bumping of the products can be prevented, and theadhesive pouring yield of the products can be guaranteed.

Description

Technical field [0001] The invention relates to a vacuum glue filling (or glue dispensing, glue injection) equipment, in particular to a fully automatic double vacuum box glue filling machine. Background technique [0002] The vacuum potting machine is a common industrial equipment used to potting products in a vacuum environment. A traditional vacuum glue filling machine usually includes a dispensing valve and a vacuum box for glue filling. [0003] Existing vacuum glue filling machines have found the following shortcomings in long-term use: [0004] 1. Whenever the product enters the vacuum box for glue filling, the vacuum box needs to be evacuated before the glue filling work, and when the product is removed from the vacuum box, the vacuum box must be pressurized in advance; due to the inside of the vacuum box Larger space results in longer vacuuming and pressurizing time, and high requirements for the power of the vacuum pump, resulting in low production efficiency, high equipm...

AI Technical Summary

Problems solved by technology

[0004] 1. Whenever the product enters the vacuum box for glue filling, the vacuum box needs to be evacuated before the glue filling work, and when the product is removed from the vacuum box, the vacuum box must be pressurized in advance; due to the inside of the vacuum box The space is large, which leads to a long time for vacuuming and pressurizing, and requires high power of the vacuum pump, so there are disadvantages such as low production efficiency, high equipment cost, and high equipment energy consumption;

[0005] 2. The transmission line and the vacuum box are located on the same horizontal straight line, and directly pass through the inside of the vacuum box. In order to facilitate the vacuum box to be closed and vacuumed, the transmission line must be segmented, and each section of the transmission line needs to be equipped with a motor, resulting in equipment The cost is high; in addition, there are gaps between each section of the transmission line, which causes different degrees of bumps every time the product enters and exits the vacuum door of the vacuum box. The smaller the product, the more obvious the bumps, especially when the product is filled with glue. Glue overflow occurs, affecting product quality;

[0006] 3. The vacuum box must be made very large for the transmission line to pass through, which further leads to a longer time for vacuuming and pressurization, and the transmission line inside the vacuum box is difficult to clean, maintain and repair
