Description

Technical Field

[0001] This invention relates to an automatic assembly equipment for door and window corner codes, belonging to the field of door and window processing technology. Background Technology

[0002] Door and window glass is usually fixed by aluminum profiles around the perimeter. Each section of the profile on the four sides needs to be spliced ​​and fixed together. The connection between each side forms a 90-degree right angle. The corner brackets are used to connect and fix each adjacent section of the profile, which plays a significant role in the overall strength and sturdiness of the door and window.

[0003] Using corner brackets to assemble door and window profiles is a common method for assembling door and window frames. First, corner brackets are inserted into the cavities at both ends of one of the profiles. Then, two other profiles without corner brackets are inserted into the corner brackets of the first profile. Corner brackets are then inserted into the cavities at both ends of the last profile. Finally, the corner brackets at both ends of the last profile are inserted into their respective cavities to form a quadrilateral door and window frame. One corner bracket secures the corner of two adjacent profiles, and four corner brackets are needed to assemble a quadrilateral door and window frame. In existing technology, the entire assembly process of the door and window profiles requires manual operation. Personnel manually pick up the corner bracket profiles one by one, insert the corner brackets into the cavities of the profiles, and then assemble multiple profiles. This is very time-consuming, labor-intensive, and the assembly accuracy is difficult to guarantee. Hammers and other tools are often used during the insertion of corner brackets, which can easily damage the profiles. Furthermore, some door and window profiles have more than one cavity inside. In this case, the splicing and fixing between two profiles requires more than one corner bracket, making the assembly process more time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of time-consuming and labor-intensive door and window assembly, high labor intensity, and difficulty in guaranteeing assembly accuracy in the existing technology, and to provide an automatic assembly equipment for door and window corner codes.

[0005] This invention is achieved through the following technical solution:

[0006] The device is an automatic assembly equipment for door and window corner codes, including a gripping mechanism and an assembly mechanism. The gripping mechanism includes a ground rail support, two ground rails on the ground rail support, a slide seat slidably installed between the two ground rails, a six-axis articulated robot installed on the slide seat, and a gripping gripper for gripping corner codes installed at the end of the six-axis articulated robot.

[0007] The assembly mechanism includes a base frame with two longitudinal guide rails and two crossbeams. One crossbeam is fixedly mounted on the base frame, and the other crossbeam is slidably mounted on the longitudinal guide rails. The crossbeam slidably mounted on the longitudinal guide rails is driven by a first lead screw and nut pair mounted on the base frame.

[0008] The crossbeam is equipped with two transverse guide rails, and each crossbeam is equipped with two corner bracket assembly platforms. One corner bracket assembly platform is fixedly installed on the crossbeam, and the other corner bracket assembly platform is slidably installed on the transverse guide rail. The corner bracket assembly platform slidably installed on the transverse guide rail is driven by a second lead screw and nut pair installed on the crossbeam.

[0009] The distance between the four corner bracket assembly platforms is adjusted by the first and second lead screw and nut pairs to accommodate the installation requirements of door and window profiles of different sizes. A six-axis articulated robot picks up the corner brackets one by one and automatically installs them into the cavities of the horizontal profiles of the door and window. The second lead screw and nut pair is activated, causing the two corner bracket assembly platforms to move the vertical profiles on them. The corner brackets at the ends of the vertical profiles are first inserted into the cavities near the ends of the horizontal profiles. As the movement continues, the other end of the horizontal profile cavity is fitted onto the corner bracket at the end of another vertical profile. After assembling one door or window, it is removed, and the assembly of the next door or window begins. This invention is used for the automatic installation of door and window corner brackets. The vertical and horizontal profiles of doors and windows are connected by corner brackets, saving time and labor, increasing production efficiency, and improving assembly accuracy, thus helping to reduce costs.

[0010] Further optimization involves a gripper with four pairs of jaws, each pair's spacing controlled by a cylinder. This cylinder-controlled jaw spacing enables the gripping of diagonal codes, providing excellent flexibility.

[0011] A further preferred embodiment includes a ground-based corner code storage mechanism. This mechanism includes a storage base with at least one strip-shaped storage slot fixedly mounted on it. The bottom of the storage slot is closed, while the top is open. Pre-stacking and storing the corner codes in the storage slot, and then using a six-axis articulated robot to control a gripper to pick them up, helps improve work efficiency.

[0012] Further optimization involves fixing a support corner plate at the inner corner of the corner bracket assembly platform to support the door and window profiles. The support corner plate has an L-shaped through hole. The corner bracket assembly platform is equipped with two limiting plates and two limiting cylinders. A rotatable limiting cylinder is mounted on the piston rod of each limiting cylinder, passing through the L-shaped through hole in the support corner plate. The limiting plate is in close contact with the end face of the support corner plate. The limiting plate limits one side of the door and window profile, while the limiting cylinder limits the other side, resulting in better limiting effect and ensuring smooth and accurate corner bracket installation. The rotatable limiting cylinder facilitates smoother movement of the profile laterally.

[0013] Further optimization reveals that the limiting cylinder has multiple piston rods, with strip plates mounted on the piston rods. A limiting cylinder is rotatably mounted on the inner end of the strip plate, with two limiting cylinders located at the inner corners of the corner bracket assembly platform. This limiting cylinder installation structure offers good stability and provides better limiting and guiding effects for door and window profiles.

[0014] Further optimization involves installing two clamping cylinders on the corner bracket assembly platform. A clamping plate is mounted on the piston rod of each clamping cylinder, and the clamping cylinders are lifting and rotating cylinders. The clamping cylinders drive the clamping plates to press the door and window profiles from top to bottom, increasing the constraint on the profiles and further improving the limiting effect. This ensures smooth and accurate installation of the corner brackets. The use of lifting and rotating cylinders allows for simultaneous lifting and rotating, resulting in a more compact installation layout on the corner bracket assembly platform.

[0015] Further preferably, the assembly mechanism also includes a loading and unloading mechanism. This mechanism comprises two strip plates, each with pulleys at both ends. A second synchronous belt is positioned between the pulleys at both ends of the strip plates. This second synchronous belt is driven by a loading and unloading conveyor motor mounted at one end of the strip plates. Two lifting mechanisms are mounted on the strip plates. These lifting mechanisms drive the loading and unloading mechanism to move up and down, loading longitudinal profiles and unloading assembled doors and windows. The loading and unloading conveyor motor drives the second synchronous belt, which, in conjunction with the lifting mechanisms, moves the longitudinal profiles or assembled doors and windows to a designated position, further improving the automation level and production efficiency of the invention.

[0016] Further preferably, the lifting mechanism includes a gear and pulley mounted on a crossbeam, and a lifting plate mounted on a strip plate. The gear and pulley are coaxially connected, and the gear meshes with a rack fixedly mounted on the side of the lifting plate. One lifting mechanism also includes a lifting motor, the shaft of which is connected to the shafts of the gear and pulley. Two pulleys on the same strip plate are connected by a first synchronous belt. The lifting motor drives the lifting plate and the strip plate to rise and fall together through gear and rack transmission. Through the first synchronous belt, one lifting motor drives the operation of two lifting mechanisms, resulting in a simple and reliable structure.

[0017] Compared with the prior art, the beneficial effects of this invention are:

[0018] The distance between the four corner bracket assembly platforms is adjusted by the first and second lead screw and nut pairs to accommodate the installation requirements of door and window profiles of different sizes. A six-axis articulated robot picks up the corner brackets one by one and automatically installs them into the cavities of the horizontal profiles of the door and window. The second lead screw and nut pair is activated, causing the two corner bracket assembly platforms to move the vertical profiles on them. The corner brackets at the ends of the vertical profiles are first inserted into the cavities near the ends of the horizontal profiles. As the movement continues, the other end of the horizontal profile cavity is fitted onto the corner bracket at the end of another vertical profile. After assembling one door or window, it is removed, and the assembly of the next door or window begins. This invention is used for the automatic installation of door and window corner brackets. The vertical and horizontal profiles of doors and windows are connected by corner brackets, saving time and labor, increasing production efficiency, and improving assembly accuracy, thus helping to reduce costs.

[0053] Working principle:

[0054] The distance between the four corner bracket assembly platforms is adjusted by the first and second lead screw and nut pairs to accommodate the installation requirements of different sized door and window profiles. Limiting plates are tightly fitted against the door and window profiles, serving a positioning function. The corner brackets are stored in a corner bracket storage box. Horizontal and vertical profiles are placed on the corner bracket assembly platforms. A six-axis articulated robot picks up the corner brackets one by one and automatically installs them into the cavities of the horizontal profiles. The second lead screw and nut pair is activated, causing the two corner bracket assembly platforms to move the vertical profiles on them. The corner bracket at the end of the vertical profile is first inserted into the cavity near the end of the horizontal profile. As it continues to move, the other end of the horizontal profile cavity is fitted onto the corner bracket at the end of another vertical profile. After assembling one door or window, it is removed, and the assembly of the next door or window begins. In addition, a lifting mechanism drives the loading and unloading mechanism to lift and lower the loading and unloading mechanism. The loading and unloading mechanism is used to load the vertical profiles and unload the assembled doors and windows. The loading and unloading conveyor motor drives the second synchronous belt, which, in conjunction with the lifting mechanism, moves the vertical profiles or assembled doors and windows to designated positions. This invention is used for the automatic installation of door and window corner brackets. The longitudinal and transverse profiles of doors and windows are connected by corner brackets, which saves time and effort in assembly, has high production efficiency and high assembly accuracy, and helps to reduce costs.
