Description

Technical Field

[0001] This invention relates to the field of door ring assembly processing technology, and more specifically to an automated production line for processing washing machine glass cover door ring assemblies. Background Technology

[0002] Door ring assemblies are typically made by bonding a spacer ring to a glass cover and are widely used in the washing machine industry. To ensure the bonding strength and sealing performance between the glass cover and the spacer ring, the two need to be pressed together after applying adhesive and then subjected to a pressure-holding and curing process for a certain period of time.

[0003] Currently, the common assembly methods for door ring components are mostly semi-automatic or manual step-by-step operations: first, the isolation ring is manually placed at the dispensing station for adhesive dispensing, then the glass cover is manually placed, and then it is sent to a simple press or pressure holding station for a single pressure holding. Although some production lines have introduced conveyor lines, the pressure holding process is often a one-time static pressure holding with a short holding time, and the handling of the iron plate (used to apply pressure evenly) also relies heavily on manual operation. Therefore, it is necessary to develop a door ring component assembly equipment that is highly integrated and automated and can achieve multiple reciprocating pressure holding to improve production efficiency, ensure bonding quality, and reduce manual intervention. Summary of the Invention

[0004] The purpose of this invention is to provide an automated production line for processing washing machine glass cover door ring assemblies, solving the following technical problems: The low level of automation results in low production efficiency. Multiple processes, such as dispensing, capping, pressure holding, and plate handling, require manual transfer or assisted positioning, leading to long cycle times and making it difficult to meet the needs of mass production.

[0005] Uneven pressure holding results in inconsistent bonding quality. During a single static pressure holding, the pressure on different areas of the glass cover and the isolation ring may be inconsistent. This is especially true for larger door frame assemblies, where the bonding strength between the edge and center areas differs significantly, making it easy for bubbles or localized delamination to occur.

[0006] The equipment occupies a large area and the production line lacks flexibility. If multiple pressure holding machines are connected in series to simulate multiple pressure holding cycles, it will significantly increase the length of the equipment and the factory floor space required, and it will be difficult to adapt to the production switchover of different specifications of door ring components.

[0007] The objective of this invention can be achieved through the following technical solutions: An automated production line for processing washing machine glass cover door ring components includes, platform; The isolation ring station is slidably installed on the platform and moves along the longitudinal direction of the platform; A dispensing machine is installed on the path of the moving isolation ring station to perform ring dispensing on the isolation ring that has moved below it.

[0011] As a further embodiment of the present invention: a first conveyor frame is provided below the positioning fixture. The first conveyor frame includes a third guide rail. A slide plate is slidably connected on the third guide rail. Two limiting plates are symmetrically arranged on the slide plate. Multiple rollers are arranged between the two limiting plates. The multiple rollers are driven to rotate by chains and sprockets. The slide plate is provided with a resettable limit block and a push plate in the direction of movement of the door ring assembly.

[0012] As a further aspect of the present invention, it also includes a double-speed chain conveyor mechanism, wherein a floor-changing elevator is provided on both sides of the double-speed chain conveyor mechanism, and a platform is provided on one side of one of the floor-changing elevators, and a pallet handling mechanism is provided on the side opposite to the platform and located on the double-speed chain conveyor mechanism. The platform and the pallet handling mechanism are connected by a floor-changing elevator equipped with a plate handling mechanism, which is used to cover the door ring assembly with iron plates.

[0013] As a further aspect of the present invention: the floor-changing elevator includes an iron plate transport frame, on which two sets of lifting components are symmetrically arranged, and each set of lifting components is equipped with a second conveyor frame, the second conveyor frame including a drag plate, a limiting plate, a roller, a limiting block, a chain and a sprocket.

[0014] As a further aspect of the present invention: the iron plate conveying mechanism includes a fourth conveying component, a sliding plate is slidably connected to the fourth conveying component, and a second suction cup is fixedly installed at the bottom of the sliding plate.

[0015] As a further aspect of the present invention: the pallet handling machine includes a pallet handling frame, a fifth conveying component is installed on the top of the pallet handling frame, a movable plate is slidably connected to the fifth conveying component, a lifting cylinder is fixedly installed on the movable plate, the piston rod of the lifting cylinder passes through the movable plate and is connected to the lifting connecting plate through a connecting rod, a second suction cup is provided at the bottom of the lifting connecting plate, a guide rod is fixedly installed at the top of the lifting connecting plate, and the top of the movable plate passes through the movable plate.

[0018] The door ring assembly of this invention reciprocates multiple times in the double-speed chain conveyor mechanism, and is lifted and layered by left and right layer-changing elevators and transferred horizontally by the pallet transport mechanism during the movement. This allows the assembly to maintain pressure continuously, avoiding the problems of uneven pressure or insufficient curing that may occur with single pressure holding. It effectively enhances the bonding strength between the glass cover and the isolation ring, ensuring the quality of the finished product.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figure 12 As shown, the washing machine glass cover door ring assembly consists of a glass cover 1, a rubber ring 2, and an isolation ring 3. PUR adhesive is applied to the isolation ring 3 to form the rubber ring 2, and then the glass cover 1 is placed on top to obtain the finished product. This production line is used to realize the automated dispensing and pressure holding process. Please see Figure 1 As shown, the present invention is an automated production line for processing washing machine glass cover door ring components, including a double-speed chain conveyor mechanism 30. A layer-changing elevator 50 is provided on both sides of the double-speed chain conveyor mechanism 30. A platform 10 is provided on one side of one of the layer-changing elevators 50, and a pallet transport mechanism 40 is provided on the opposite side of the platform 10 and located on the double-speed chain conveyor mechanism 30. An iron plate transport mechanism 20 is provided on the layer-changing elevator 50 between the platform 10 and the pallet transport mechanism 40 for covering the door ring component with an iron plate.

[0025] In this embodiment, the isolation ring 3 is treated with adhesive on the platform 10, and the glass cover 1 is placed on the isolation ring 3 for pressure holding to obtain the door ring assembly. Then, the door ring assembly is pushed into the right-side floor-changing elevator 50, which lifts it to below the iron plate transport mechanism 20. The iron plate transport mechanism 20 places the iron plate on the glass cover 1, and then enters the double-speed chain conveyor mechanism 30 for reciprocating pressure holding and transport. During the reciprocating motion of the door ring assembly, the lifting direction is changed by the left and right floor-changing elevators 50, and the horizontal direction is changed by the pallet transport mechanism 40, so that the door ring assembly reciprocates eight times. Before taking out the door ring assembly, the iron plate is removed by the iron plate transport mechanism 20, and finally the finished product is taken out.

[0026] In this embodiment, through multiple processes such as dispensing adhesive to the isolation ring, feeding the glass cover, holding pressure, automatic placement and removal of the iron plate, reciprocating pressure holding of the door ring assembly in the double-speed chain conveyor mechanism, layer changing lifting and horizontal transfer, a fully automated continuous operation from the isolation ring to the finished door ring assembly is realized, which significantly reduces the need for manual operation and improves production consistency.

[0027] See Figure 2 As shown, the platform 10 is equipped with a first conveying guide rail 102, an isolation ring station 101, a first conveying assembly 103, a dispensing machine 1031, a glass cover station 107, a second conveying assembly 104, a third conveying assembly 106, and a first conveying frame 108. The first conveying guide rail 102 is fixedly installed on the platform 10, and the isolation ring station 101 is slidably connected to the first conveying guide rail 102. The isolation ring station 101 holds the isolation ring, and its shape is adapted to the isolation ring. Multiple limiting posts are arranged in a ring shape inside the isolation ring station 101. The isolation ring has a through-hole structure, and the limiting posts pass through the through-hole of the isolation ring. Combined with the shape of the isolation ring station 101, these posts are used to limit the movement of the isolation ring. A servo motor, lead screw, or cylinder can be installed inside the first conveying guide rail 102 to drive the isolation ring station 101 to move along the longitudinal direction of the platform 10. A first conveying assembly 103 is installed on the path of the isolation ring station 101. It is perpendicular to the first conveying guide rail 102. A dispensing machine 1031 is installed on the first conveying assembly 103. By driving the dispensing machine 1031 and the isolation ring station 101 to move through the first conveying assembly 103 and the first conveying guide rail 102 respectively, the dispensing machine 1031 can perform ring dispensing on the isolation ring. A glass cover station 107 is fixedly installed on one side of the isolation ring station 101. A glass cover is placed on the glass cover station 107. Multiple positioning cylinders are set on the glass cover station 107. Positioning blocks are installed on the piston rods of the positioning cylinders for center positioning of the glass cover. The second conveying assembly 104 is arranged parallel to the moving path of the isolation ring station 101. A robot arm is provided on the second conveying assembly 104 for placing the glass cover on the isolation ring on the pressure holding station 105. The third conveying assembly 106 is arranged perpendicular to the second conveying assembly 104. Two robots with a gap are provided on the third conveying assembly 106 for synchronously conveying the dispensing isolation ring and the pressure-held door ring assembly to the pressure holding station 105 and the positioning fixture 109. In this embodiment, the first conveying component 103, the second conveying component 104, and the third conveying component 106 can all be a combination of a synchronous belt and a synchronous pulley, a servo motor and a lead screw, and a cylinder, thereby driving the robot arm or the dispensing machine 1031 to move; the dispensing machine 1031 dispensing glue is a conventional technical means, and will not be described in detail here.

[0028] See Figure 3 As shown, the robotic arm includes a first cylinder 1041, a fixed plate 1042 is fixedly mounted on the piston rod of the first cylinder 1041, and a plurality of first suction cups 1043 are mounted on the bottom of the fixed plate 1042 in order to adsorb the circular structure.

[0029] See Figure 3 As shown, the pressure holding station 105 is located on the moving path of the second conveying assembly 104. The pressure holding station 105 includes two symmetrically arranged second conveying guide rails 1052. A pressure holding placement plate 1051 is slidably connected to the second conveying guide rails 1052. The pressure holding placement plate 1051 can be driven to move by a servo motor, lead screw, or cylinder. The pressure holding placement plate 1051 is provided with a clamp for clamping the workpiece. For example, multiple cylinders can be used in conjunction with arc-shaped blocks for clamping and limiting. See Figure 3 As shown, the pressure holding station 105 also includes four support columns 1053 located on both sides of the second conveying guide rail 1052. A support plate 1054 is fixedly installed on the top of the support column 1053. A second cylinder 1055 is fixedly installed at the center of the top of the support plate 1054. The piston rod of the second cylinder 1055 passes through the support plate 1054 and is connected to the pressure holding plate 1056. The pressure holding plate 1056 slides up and down on the support column 1053.

[0030] In this embodiment, the glass cover and the isolation ring are first placed on the glass cover station 107 and the isolation ring station 101 respectively by a robotic arm or manually. Then, the isolation ring is moved to the underside of the dispensing machine 1031 by the first conveying guide rail 102, and the dispensing machine 1031 applies a ring of glue to the upper surface of the isolation ring. Then, the third conveying assembly 106 moves, causing one robotic arm to land above the isolation ring station 101 and the other robotic arm to land above the pressure holding plate 1051. Then, one of the robotic arms picks up the dispensed isolation ring. The glass cover is moved and placed onto the pressure holding plate 1051; then, the glass cover is adsorbed by the second conveying assembly 104 and the robotic arm on it, moved and placed onto the isolation ring; finally, the pressure holding plate 1051 is moved to below the pressure holding plate 1056 by the second conveying guide rail 1052, and the second cylinder 1055 drives the pressure holding plate 1056 to descend and maintain pressure on the glass cover and the isolation ring; after pressure maintenance, the product is reset, and at this time, another robotic arm on the third conveying assembly 106 will adsorb and transfer the finished product. The two robotic arms achieve synchronous reciprocating motion.

[0031] In this embodiment, the structure enables automated dispensing and pressure holding processes, saving manpower and improving efficiency.

[0032] See Figure 4As shown, the platform 10 also includes a first conveyor frame 108 disposed on one side of the glass cover station 107. The first conveyor frame 108 includes a third guide rail 1081, on which a slide plate 1089 is slidably connected. The slide plate 1089 has an H-shaped structure and can be moved by a servo motor, lead screw, or cylinder. Two limiting plates 1082 are symmetrically disposed on the slide plate 1089, and multiple rollers 1083 are disposed between the two limiting plates 1082. The multiple rollers 1083 are driven to rotate by a chain 1087 and a sprocket 1088, one of which can be driven to rotate by a servo motor. Every two rollers 1083 are connected by a chain 1087. Among them, a resettable limit block 1086 and a push plate 1085 are provided on the slide plate 1089 and in the direction of movement of the door ring assembly. The push plate 1085 is pushed to move left and right by the push cylinder 1084 to limit it. The limit block 1086 is driven to rise and fall by the vertical cylinder provided below it to limit it, thus limiting the positioning fixture 109. In this embodiment, the third guide rail 1081 drives the slide plate 1089 to move below the robot arm, placing the finished product on the positioning fixture 109. When it is conveyed out, the chain 1087 and sprocket 1088 drive multiple rollers 1083 to rotate, thereby conveying the positioning fixture 109 out. At the same time, the cylinder 1084 can drive the push plate 1085 to push the positioning fixture 109 out.

[0033] See Figure 5 As shown, the positioning fixture 109 includes a base plate 1091, which is placed on multiple rollers 1083. The top of the base plate 1091 has multiple limiting posts 1092 of varying heights to support the door ring assembly. Multiple guide wheels 1093 are provided along the edge of the base plate 1091. These guide wheels 1093 contact the frame of the speed-multiplying chain 302, achieving rolling friction to protect the base plate 1091 and increase its service life.

[0034] See Figure 6-9As shown, the floor-changing elevator 50 includes a steel plate transport frame 501. Two sets of lifting components 502 are symmetrically arranged on the steel plate transport frame 501, which can be driven by servo motors and lead screws. Each set of lifting components 502 is equipped with a second conveyor frame 503. The second conveyor frame 503 includes a slide plate, limit plates, rollers, limit blocks, chains, and sprockets, similar in structure to the first conveyor frame 108. The slide plate is fixedly installed on the lifting components 502. Two limit plates are symmetrically arranged on the slide plate, and multiple rollers are arranged between the two limit plates. The multiple rollers are driven to rotate by chains and sprockets, one of which can be driven by a servo motor. Every two rollers are connected by a chain drive. Two resettable limit blocks are symmetrically arranged on the slide plate and in the direction of movement of the door ring assembly. The limit blocks are driven to rise and fall by cylinders to limit the movement of the door ring assembly. In this embodiment, one set of lifting components 502 is activated, which drives the second conveyor frame 503 to descend to a position parallel to the first conveyor frame 108. Then, the first conveyor frame 108 conveys the door ring assembly onto the second conveyor frame 503, and the limiting block rises to limit the door ring assembly. See Figure 9 As shown, the iron plate conveying mechanism 20 includes a fourth conveying component 201, which may consist of a synchronous pulley and a synchronous belt, a servo motor and a lead screw or cylinder. A sliding plate 202 is slidably connected to the fourth conveying component 201, and four second suction cups 203 are connected to the bottom of the sliding plate 202. The right lifting component 502 will limit the door ring component to the top through the second conveying frame 503. At this time, the second suction cups 203 will place the suctioned iron plate on the door ring component for pressure holding, and then drive the chain and sprocket to rotate, drive the roller to rotate, and then transport the door ring component to the double speed chain conveying mechanism 30. In this embodiment, when the door ring assembly is to be output, the lifting assembly 502 on the left will move the door ring assembly to the top through the second conveyor frame 503. At this time, the sliding plate 202 moves to the left and uses the second suction cup 203 to pick up the iron plate on the door ring assembly. Then it moves to the right and is placed on the next door ring assembly to maintain pressure. This back-and-forth movement continues.

[0035] See Figure 10As shown, the double-speed chain conveyor mechanism 30 includes a double-speed chain conveyor frame 301, on which two symmetrical left and right sets of double-speed chain groups are arranged. Each set of double-speed chain groups consists of four layers of symmetrical double-speed chains 302. The two double-speed chains 302 in each layer are driven to rotate by a motor. The transmission of the double-speed chain 302 is existing technology and will not be described in detail here. In this embodiment, there are 8 pairs of double-speed chains 302. The movement trajectory of the door ring assembly conveyed from the second conveyor frame 503 on the double-speed chains 302 is as follows: it is first conveyed from the bottom right pair of double-speed chains 302. When it is transported to the second conveyor frame 503, it is transferred to the second layer by the layer-changing elevator 50 and then transported to the third and fourth layers. When it moves to the end of the fourth layer, it is transported to the top layer of the left double-speed chain group by the pallet transport mechanism 40, and then reciprocates until it reaches the bottom layer of the left double-speed chain 302 for transport. It is then transported to the second conveyor frame 503, where the iron plate is picked up by the second suction cup 203 and then transported to the first conveyor frame 108 by the second conveyor frame 503 to remove the finished product.

[0036] In this embodiment, the iron plate allows the door ring assembly to maintain continuous pressure and enables continuous integrated production of the entire product, saving floor space.

[0037] See Figure 10 and 11 As shown, the pallet handling mechanism 40 includes a pallet handling frame 401. A fifth conveying assembly 402 is installed on the top of the pallet handling frame 401. A movable plate 403 is slidably connected to the fifth conveying assembly 402. A lifting cylinder 404 is fixedly installed on the movable plate 403. The piston rod of the lifting cylinder 404 passes through the movable plate 403 and is connected to a lifting connecting plate 406 through a connecting rod. A third suction cup 407 is provided at the bottom of the lifting connecting plate 406. A guide rod 405 is fixedly installed on the top of the lifting connecting plate 406. The top of the movable plate 403 passes through the movable plate 403.

[0038] In this embodiment, the lifting cylinder 404 is activated, which in turn drives the lifting connecting plate 406 to descend, which in turn drives the third suction cup 407 to descend. The third suction cup 407 contacts the door ring assembly and adsorbs it. Then, the moving plate 403 is activated to slide and change the speed chain group.

[0039] Working principle of the invention: On platform 10, the isolation ring 3 is treated with adhesive, and the glass cover 1 is placed on the isolation ring 3. The pressure is maintained at the pressure station 105 to obtain the door ring assembly. Then, the first conveyor 108 is used to transport it to the second conveyor 503 of a right-side floor-changing elevator 50. The floor-changing elevator 50 raises it to below the iron plate transport mechanism 20. The iron plate transport mechanism 20 places the iron plate on the glass cover 1. Then, the second conveyor 503 pushes the door ring assembly into the double-speed chain conveyor 30 for repeated pressure maintenance. During the reciprocating motion of the door ring assembly, the two floor-changing elevators 50 on the left and right sides will change the lifting direction, and the pallet transport mechanism 40 will transfer it horizontally, so that the door ring assembly reciprocates eight times. Before taking out the door ring assembly, the iron plate will be removed by the iron plate transport mechanism 20. The door ring assembly is then transported to the first conveyor 108 by the second conveyor 503, and finally the finished product is taken out.

[0040] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
