KR-102961595-B1 - Method for assembling window screen frame corners

Abstract

The present invention relates to a method for assembling connecting members for the corners of an insect screen, and more specifically, to an improved method for assembling connecting members for the corners of an insect screen that not only improves productivity by automating the assembly of connecting members when connecting and fixing insect screen frames to form a single insect screen, but also eliminates the confusion caused by left-right mismatch that occurred during manual assembly and improves work convenience, as the connecting members are automatically classified and assembled due to the characteristic of the connecting members being distinguishable left and right, thereby contributing to cost reduction.

Claims (2)

1. A part preparation stage comprising a body that is automatically cut after injection molding and then separated into left and right sides for storage, a wheel and a rivet pin, and a jig which is a fixing mechanism for assembling them; A wheel mounting step of positioning the wheel by fitting it onto the above jig; A jig insertion step in which the body is loaded and meets the jig, and the body is mounted on the jig to set the position where the wheel is to be installed; A rivet pin insertion step of inserting a rivet pin through the shaft hole of a wheel to form the wheel shaft of a wheel inserted into a body; A riveting step in which, when the body is conveyed by a jig feeder and set in a riveting machine, the riveting machine operates to rivet a rivet pin; Jig detachment step for separating the jig from the body; A method for assembling a mosquito net corner connecting member, characterized by including the step of the detached body being returned to an unloading position by a conveyor and then ejected through a product ejector.
2. In paragraph 1, A method for assembling a mosquito net corner connecting member, characterized by the process of preparing the body in the above-mentioned part preparation step, comprising: a first process in which a pair of injection-molded left and right bodies are ejected from an injection molding machine as a body product in which the sprue (10a) and the runner (10b) connected to the sprue (10a) are attached; a second process in which the body product ejected through the first process passes through a cutting machine to cut and remove the sprue (10a) and the runner (10b) so that it becomes a left body or a right body; and a third process in which, after the second process, the left body is stored in the left storage compartment and the right body is separated and stored in the right storage compartment through a body separator (10c).

Description

Method for assembling window screen frame corner connectors The present invention relates to a method for assembling connecting members for the corners of an insect screen, and more specifically, to an improved method for assembling connecting members for the corners of an insect screen that not only improves productivity by automating the assembly of connecting members when connecting and fixing insect screen frames to form a single insect screen, but also eliminates the confusion caused by left-right mismatch that occurred during manual assembly and improves work convenience, as the connecting members are automatically classified and assembled due to the characteristic of the connecting members being distinguishable left and right, thereby contributing to cost reduction. As the technological capabilities of the window and door industry are becoming increasingly standardized and consumer awareness regarding thermal transmittance, insulation, and airtightness is expanding, high-efficiency products are being released into the industry at a rapid pace. As competition for luxury upgrades intensifies among redevelopment and reconstruction apartments centered on urban areas, a trend toward luxury is also sweeping through the window and door market. In response to this trend, window manufacturers are introducing high-end windows. For example, as shown in the figure below, high-end windows are manufactured using aluminum for the exterior windows facing the outside and PVC for the interior windows facing the inside of the building to ensure excellent thermal insulation and a luxurious design. In this case, since aluminum is used for the exterior window, the insect screen facing the exterior must also be an aluminum insect screen. As the AL+ PVC window market expands, the demand for aluminum insect screens is also expected to gradually increase. Insect screens are installed on the outside of glass windows to allow ventilation into the interior, primarily during the summer, while preventing harmful insects from entering. They consist of a mesh supported by horizontal and vertical frames made of synthetic resin or aluminum, corner connectors that link the corners of the frames, and rubber gaskets. In this case, by incorporating an anti-detachment system into the upper corner connecting member constituting the insect screen, it has the advantage of reliably preventing the insect screen from detaching from the window frame rail. In addition, since insect screens are mostly made of thin metal mesh, separate rollers (without height adjustment capabilities) are sometimes installed at the bottom of the frame; however, this work must be performed separately and is entirely manual, which has the disadvantage of being very cumbersome and incurring additional costs. Furthermore, if the work is done incorrectly, the height may not match, which can actually cause more inconvenience when opening and closing the insect screen. FIG. 1 is an exemplary diagram of an insect screen corner connecting member to explain the assembly method according to the present invention. FIG. 2 is an exemplary sample photograph of an assembly facility to explain the assembly method according to the present invention. FIG. 3 is a process flowchart illustrating an assembly method according to the present invention. FIG. 4 is an explanatory diagram of the body preparation process among the assembly methods according to the present invention. Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings. Prior to describing the present invention, the following specific structural or functional descriptions are provided merely for the purpose of illustrating embodiments according to the concept of the present invention. Embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described herein. In addition, since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, specific embodiments are illustrated in the drawings and described in detail in this specification. However, this is not intended to limit the embodiments according to the concept of the present invention to specific disclosed forms, and it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention. The present invention improves the assembly process by pre-setting rollers on the corner connecting members of the insect screen so that they can be installed on a window in an assembled state, thereby improving the sliding ability of the insect screen and reducing the cost and time associated with the assembly work. In particular, the lower corner of the window screen frame corners is composed of parts including a plastic body, a wheel, and a rivet p
