Description

Technical Field

[0001] The invention relates to a door and window gluing device, in particular to an automatic door and window gluing machine, and belongs to the technical field of mechanical equipment for building decoration. Background Art

[0002] With the increase in demand for commercial and residential buildings in my country, the demand for doors and windows is also increasing year by year. At present, the doors and windows used in my country are mainly rectangular, composed of glass and profiles. During the processing, sealant or sealing strips need to be applied between the glass and the profiles. The sealing method of adding sealing strips has many disadvantages. The sealing strip installation process is complicated, the sealing strip is easy to age, there are interfaces between the horizontal and vertical sealing strips, and the sealing effect is poor. It has gradually been replaced by the method of applying sealant. The existing door and window gluing methods are mainly manual and single-machine production. Due to the heavy glass, manual gluing requires the glass to be turned over and the workbench to be put on and off during the production process. These all require manual operation, so the labor intensity is high, the efficiency is low, the loss is high, the appearance is poor and uncontrollable, the quality is unstable, and the quality requirements of the workers are high; and the existing gluing equipment is single-sided gluing, the degree of automation is relatively low, and it is necessary to wait for the sealant to have a certain strength before it can be transferred and transported, which is time-consuming, inefficient, and requires a large production site. In order to improve production efficiency, some people have improved the existing gluing machines, such as the utility model patent for a double-sided door and window gluing machine designed by Cao Weibing and Qiu Yong and published by the State Intellectual Property Office on March 2, 2018, with patent number 201720471793.4. The patent includes a door and window conveying device, a gantry, an upper gluing unit and a lower gluing unit. A gantry is provided above the door and window conveying device, and an upper gluing unit is installed on the gantry. A lower gluing unit corresponding to the upper gluing unit is provided below the door and window conveying device. Both the upper gluing unit and the lower gluing unit are provided with glue valves for controlling glue discharge. The gantry can move along the X-axis driven by the traveling gear, and the upper gluing unit and the lower gluing unit can move along the Y-axis driven by the upper ball screw and the lower ball screw respectively; the upper gluing unit and the lower gluing unit can also move along the Z-axis and rotate the gluing head on the spot. However, this type of glue spraying machine has not been put on the market, and there are many problems, especially the installation, debugging and use of the lower glue spraying unit are inconvenient, and the glue spraying quality cannot be intuitively observed and controlled.
