Screen assembly net pulling mechanism, screen assembly device and method

Abstract

The present application belongs to the technical field of door and window processing, and proposes a screen window assembly net pulling mechanism, screen window assembly equipment and method. A first feeding execution part and a second feeding execution part are arranged on a fixed plate. The feeding execution part with insufficient or used-up screen net material is moved out of the feeding area by driving the roll changing driving part, and the other feeding execution part enters the feeding area, so that the feeding does not need to stop working. The pushing force of the upper clamping plate driving part is greater than that of the lower clamping plate driving part, and the stroke of the lower clamping plate driving part is greater than that of the upper clamping plate driving part. In the net pulling process, the first feeding execution part is opened, and after the net pulling is completed, the first feeding execution part is closed. After the net pulling is completed, the upper clamping plate driving part continues to extend outward, pushes the upper clamping plate and the lower clamping plate downward, and at the same time, pushes the lower clamping plate driving part to extend outward. The clamping jaw keeps a closed state while moving downward, covers the screen net on the screen window, and fixes the screen net, without the need to separately arrange a lifting mechanism.

Description

Technical Field

[0001] This invention belongs to the field of door and window processing technology, and particularly relates to a screen window assembly mesh pulling mechanism, screen window assembly equipment and method. Background Technology

[0002] In automated equipment for door and window processing, the automated installation of screen mesh is a crucial step. The installation of screen mesh includes steps such as pulling the mesh, laying the mesh, and fixing the mesh with adhesive strips.

[0003] Currently, in automated door and window processing equipment, when the mesh pulling mechanism is insufficient, the machine needs to be stopped for material replacement before restarting, affecting work efficiency. In addition, after the mesh pulling action is completed, the mesh needs to be laid on the upper surface of the screen window to prepare for subsequent mesh fixing. However, during the mesh laying process, a lifting mechanism needs to be independently set on the mesh pulling mechanism to realize the mesh laying action. The entire mesh pulling mechanism descends to realize the mesh laying action, which not only requires complex structural and control logic design to cooperate with the lifting mechanism, but also increases the vibration of the entire screen window assembly equipment due to the lifting of the entire mesh pulling mechanism, affecting stability and the installation quality of the mesh. Summary of the Invention

The thrust of the upper clamping plate drive component is greater than that of the lower clamping plate drive component, and the stroke of the lower clamping plate drive component is greater than that of the upper clamping plate drive component.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] like Figure 1 As shown, one embodiment of the present invention provides a screen window assembly device, including a bed 1, a screen pulling mechanism 2, a screen window fixing position 3 and a screen fixing mechanism 4 disposed on the bed 1.

[0021] The bed 1 is the supporting structure of the entire assembly equipment. Optionally, the bed 1 is constructed by welding together steel structures. The bed 1 is equipped with four legs, each of which has a retractable adjustment part to adapt to uneven installation ground.

[0022] like Figure 2 As shown, the mesh pulling mechanism 2 includes a feeding component 21 disposed at one end of the bed 1 and a pulling component 22 disposed at the other end of the bed 1. Specifically, the feeding component 21 assists in the storage and feeding of the mesh material; the pulling component 22 can move on the bed 1 and is responsible for pulling the mesh from the feeding component 21 to cover the screen at the screen fixing position 3 for subsequent fixing of the mesh.

[0023] like Figure 3 As shown, the feeding assembly 21 includes a frame 211 disposed at one end of the bed 1, a fixed plate 213 disposed on the frame 211 via a roll changing drive 212, a slide rod 214 disposed on the bed 1 and slidably connected to the fixed plate 213, and a first feeding execution part 216 and a second feeding execution part 217 disposed on the fixed plate 213 via a feeding drive 215.

[0024] The frame 211 can be made of steel; the roll-changing drive unit 212 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor or other drive equipment, capable of driving the fixed plate 213 to move up and down relative to the frame 211. The first feeding execution unit 216 and the second feeding execution unit 217 are respectively disposed at the upper and lower ends of the fixed plate 213. Through the up and down movement of the fixed plate 213, the switching of the first feeding execution unit 216 and the second feeding execution unit 217 in the feeding area can be realized; the fixed plate 213 is provided with Multiple sleeves are provided, each sleeve having a sliding rod 214 slidably connected inside; both ends of the sliding rod 214 are connected to the frame 211; the feeding drive 215 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor or other driving device, capable of pushing the first feeding execution part 216 or the second feeding execution part 217 horizontally. When the pulling assembly 22 receives material, the feeding drive 215 can push the first feeding execution part 216 or the second feeding execution part 217 out of the frame 211, facilitating the clamping of the yarn by the pulling assembly 22.

[0025] In one embodiment, the first feeding execution unit 216 is first adjusted to the feeding area. When the remaining yarn in the feeding area is insufficient or exhausted, the fixed plate 213 is driven to rise by the roll-changing drive 212, the first feeding execution unit 216 moves out of the feeding area, and the second feeding execution unit 217 enters the feeding area. During the use of the yarn in the second feeding execution unit 217, the first feeding execution unit 216 is replenished without stopping the machine. Similarly, when the remaining yarn in the feeding area is insufficient or exhausted, the fixed plate 213 is driven to fall by the roll-changing drive 212, the second feeding execution unit 217 moves out of the feeding area, and the first feeding execution unit 216 enters the feeding area. During the use of the yarn in the first feeding execution unit 216, the second feeding execution unit 217 is replenished.

[0026] like Figure 3 and Figure 4As shown, the first feeding execution unit 216 includes a first support plate 2161 disposed on the feeding drive member 215, a first upper clamping plate drive member 2162 disposed on the first support plate 2161, a first upper clamping plate 2163 disposed at the output end of the first upper clamping plate drive member 2162, a first lower clamping plate drive member 2164 disposed on the first support plate 2161, a first lower clamping plate 2165 disposed at the output end of the first lower clamping plate drive member 2164, and a first yarn roll 2166, a first stop roller 2167, a first drive roller 2168 and a first driven roller 2169 disposed on the frame 211.

[0027] The first upper clamping plate drive component 2162 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor, or other drive device, capable of driving the first upper clamping plate 2163 to move up and down. The first upper clamping plate 2163 is configured with a concave-convex structure. The first lower clamping plate drive component 2164 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor, or other drive device, capable of driving the first lower clamping plate 2165 to move up and down. The first lower clamping plate 2165 is configured with a concave-convex structure. The first yarn roll 2166, the first stop roller 2167, the first drive roller 2168, and the first driven roller 2169 are all rotatably mounted on the frame 211. A mesh is mounted on the first yarn roll 2166, and the first stop roller 2167 guides the mesh. The first drive roller 2168 and the first driven roller 2169 are symmetrically arranged, and the two sides of the mesh are in contact with the first drive roller 2168 and the first driven roller 2169, respectively. The first drive roller 2168 can be connected to a motor or other equipment to actively drive the mesh for conveying.

[0028] like Figure 3 and Figure 4 As shown, the second feeding execution unit 217 includes a second support plate 2171 disposed on the feeding drive member 215, a second upper clamping plate drive member 2172 disposed on the second support plate 2171, a second upper clamping plate 2173 disposed at the output end of the second upper clamping plate drive member 2172, a second lower clamping plate drive member 2174 disposed on the second support plate 2171, a second lower clamping plate 2175 disposed at the output end of the second lower clamping plate drive member 2174, and a second yarn roll 2176, a second stop roller 2177, a second drive roller 2179 and a second driven roller 2179 disposed on the frame 211.

[0029] The second upper clamping plate drive component 2172 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor, or other drive device, capable of driving the second upper clamping plate 2173 to move up and down. The second upper clamping plate 2173 is configured with a concave-convex structure. The second lower clamping plate drive component 2174 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor, or other drive device, capable of driving the second lower clamping plate 2175 to move up and down. The second lower clamping plate 2175 is configured with a concave-convex structure. The second yarn roll 2176, the second stop roller 2177, the second drive roller 2178, and the second driven roller 2179 are all rotatably mounted on the frame 211. A mesh is mounted on the second yarn roll 2176, and the second stop roller 2177 guides the mesh. The second drive roller 2178 and the second driven roller 2179 are symmetrically arranged, and the two sides of the mesh are in contact with the second drive roller 2178 and the second driven roller 2179, respectively. The second drive roller 2178 can be connected to a motor or other equipment to actively drive the mesh for conveying.

[0030] like Figure 2 and Figure 5 As shown, the material pulling assembly 22 includes a material pulling drive 221 disposed on the bed 1, a third support plate 222 connected to the material pulling drive 221 and slidably disposed on the bed 1 via a slide rail or other device, a third upper clamping plate drive 223 disposed on the third support plate 222, a third upper clamping plate 224 disposed at the output end of the third upper clamping plate drive 223, a third lower clamping plate drive 225 disposed on the third support plate 222, and a third lower clamping plate 226 disposed at the output end of the third lower clamping plate drive 225.

[0031] The material pulling drive 221 can be a chain conveyor, belt conveyor, telescopic rod, linear motor, or other conveying equipment, capable of driving the material pulling assembly 22 to move on the bed 1. The third upper clamping plate drive 223 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor, or other drive equipment, capable of driving the third upper clamping plate 224 to move up and down. The third upper clamping plate 224 is configured with a concave-convex structure. The third lower clamping plate drive 225 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor, or other drive equipment, capable of driving the third lower clamping plate 226 to move up and down. The third lower clamping plate 226 is configured with a concave-convex structure. The concave-convex structure of the clamping plate in the first feeding execution unit 216 corresponds slightly to the concave-convex structure of the clamping plate in the second feeding execution unit 217, facilitating the clamping of the yarn by the second feeding execution unit 217.

[0032] However, the thrust of the first upper clamping plate drive member 2162, the thrust of the second upper clamping plate drive member 2172, and the thrust of the third upper clamping plate drive member 223 are respectively greater than the thrust of the first lower clamping plate drive member 2164, the thrust of the second lower clamping plate drive member 2174, and the thrust of the third lower clamping plate drive member 225; the stroke of the first lower clamping plate drive member 2164, the stroke of the second lower clamping plate drive member 2174, and the stroke of the third lower clamping plate drive member 225 are respectively greater than the stroke of the first upper clamping plate drive member 2162, the stroke of the second upper clamping plate drive member 2172, and the stroke of the third upper clamping plate drive member 223. The upper and lower clamping plates constitute a clamp, and the clamp has two working positions, upper and lower, with two opening and closing actions in each position. Opening: The upper clamping plate driver retracts, and the lower clamping plate driver extends. Closing: The upper clamping plate driver retracts, and the lower clamping plate driver retracts. Closing: The upper clamping plate driver extends, and the lower clamping plate driver retracts. Due to the large thrust of the upper clamping plate driver, the lower clamping plate driver can be moved to the lower workstation while maintaining the clamped and closed state, facilitating the fixing of the mesh.

[0033] Lower opening: The upper clamping plate driver extends, and the lower clamping plate driver extends. Since the lower clamping plate driver has a larger stroke, the upper clamping plate driver and the lower clamping plate driver can be separated by the stroke difference opening distance, so as to realize the lower station opening state after the mesh is fixed.

[0034] Based on the screen window assembly equipment of the present invention, an embodiment of the present invention also provides a screen window assembly method, including: the second feeding execution unit 217 moves to the first feeding execution unit 216, the second feeding execution unit 217 grips the screen mesh (the corresponding jaw action is upward opening). (Upper closing); at the same time, the first feeding actuator 216 extends outward (the corresponding jaw action is upper closing). (Opening from top). After the second feeding execution unit 217 clamps the mesh and resets, it realizes the mesh pulling action. During the mesh pulling process, the first feeding execution unit 216 moves to open from top. After the mesh pulling is completed, the first feeding execution unit 216 moves to close from top. After the mesh pulling is completed, the upper clamping plate drive member continues to extend outward, pushing the upper clamping plate and the lower clamping plate to descend. At the same time, it pushes the lower clamping plate drive member to extend outward. While the clamps remain closed, they move downward and switch to the closed state, covering the mesh on the screen window for subsequent mesh fixing.

[0035] The screen window fixing position 3 is the placement position of the screen window, and the screen mesh fixing mechanism 4 is used for applying glue, pressing the glue strip, etc. The screen window fixing position 3 and the screen mesh fixing mechanism 4 can be implemented by conventional technology, which will not be described in detail here.

[0036] The above description is merely a preferred embodiment of this practice and is not intended to limit the scope of this practice. Various modifications and variations can be made to this practice by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this practice should be included within the protection scope of this practice.
