[0002] The washing machine door-close test is a safety test. Its main purpose is to ensure that the spin-dry tub stops spinning very quickly when the washing machine door is opened, in order to prevent injury to the human body.

[0003] When a washing machine is in use, the spin-dry tub rotates at high speed, and the clothes spin along with it, distributing themselves irregularly around the circumference of the tub. If you put your hand into the tub at this time, you could get tangled in the clothes and cause serious injury. Therefore, it is essential that the spin-dry tub stops rotating very quickly when the washing machine door is opened to prevent injury.

[0004] In addition to safety checks, the washing machine door inspection also includes checking the door itself. First, observe whether the door is deformed, damaged, or loose. If a problem is found, the door can be replaced directly. If there are no problems, further check whether the sealing strip on the door is intact and whether there are signs of severe wear or aging.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-2 As shown, this utility model discloses a washing machine door cover qualification testing device. The washing machine door cover qualification testing device includes a mounting frame 1, a driving device 2, and a suction device 3. The suction device 3 is mounted on the driving device 2, and the driving device 2 is mounted on the mounting frame 1. The mounting frame 1 includes a mounting cabinet 11 and a fixing frame 12. The driving device 2 is mounted on the fixing frame 12, and both ends of the driving device 2 are connected to the inside of the mounting cabinet 11.

[0030] By adopting the above technical solution, through the cooperation of the drive device 2 and the suction device 3, the closing process of the washing machine door can be accurately simulated, thereby accurately detecting the qualification of the door. The equipment adopts an automated drive mode, which can quickly and continuously detect multiple washing machine door covers, improving detection efficiency. The equipment can be adjusted and adapted according to the characteristics of different models of washing machine door covers, thereby realizing the qualification detection of door covers of various models of washing machines.

[0031] The suction door device 3 includes a first suction door device 31 and a second suction door device 32. The first suction door device 31 is installed on the upper rear side of the mounting bracket 1, and the second suction door device 32 is installed on the front side of the mounting bracket 1.

[0032] By adopting the above technical solution, and by setting two suction door devices at different positions on the mounting frame 1, space can be made more fully, enabling the equipment to achieve more functions within a limited space. The first suction door device 31 and the second suction door device 32 can work separately or simultaneously, thereby flexibly adjusting the detection method according to actual needs and improving the adaptability to washing machine door covers of different models and sizes.

[0033] The first suction door device 31 includes a first connecting rod 311 and a first suction cup 312. One end of the first connecting rod 311 is connected to the tail end of the first suction cup 312, and the other end of the first connecting rod 311 is connected to the driving device 2.

[0034] The second suction door device 32 includes a second connecting rod 321 and a second suction cup 322. One end of the second connecting rod 321 is connected to the tail end of the second suction cup 322, and the other end of the second connecting rod 321 is connected to the drive device 2.

[0035] By adopting the above technical solution, the power of the drive device 2 can be effectively transmitted to the suction cups through the connection between the connecting rods (first connecting rod 311 and second connecting rod 321) and the suction cups (first suction cup 312 and second suction cup 322), thereby achieving accurate adsorption and control of the washing machine door cover. The design of the connecting rods allows the suction cups to move within a certain spatial range, which enables the device to adapt to washing machine door covers of different sizes and positions, improving the adaptability of the device. The structure of the connecting rods can enhance the support for the suction cups, so that the suction cups can remain stable during the adsorption and release of the door cover.

[0036] The drive device 2 includes a first drive structure 21 and a second drive structure 22. The first drive structure 21 is installed in the mounting cabinet 11 on the side of the first suction door device 31, and the second drive structure 22 is installed above the second suction door device 32.

[0037] By adopting the above technical solution, by installing drive structures on the side of the first suction door device 31 and above the second suction door device 32 respectively, the workload can be effectively distributed, avoiding excessive pressure on a single drive structure, thereby extending the service life of the equipment. The first drive structure 21 is installed inside the mounting cabinet 11, which can make full use of the space and make the overall structure more compact; while the second drive structure 22 is installed above the second suction door device 32, which helps to keep the work area clean.

[0038] The first drive structure 21 includes a first drive motor 211 and a first drive rod 212. The first drive rod 212 is connected to the first drive motor 211, and the first drive motor 211 controls the rotation of the first drive rod 212.

[0039] The second drive structure 22 includes a second drive motor 221 and a second drive rod 222. The second drive rod 222 is connected to the second drive motor 221, and the second drive motor 221 controls the rotation of the second drive rod 222.

[0040] By adopting the above technical solution, two independent drive motors (first drive motor 211 and second drive motor 221) provide power to their respective drive rods (first drive rod 212 and second drive rod 222), ensuring that the equipment can complete operations such as adsorbing, transferring, and releasing the washing machine door lid. Since motor drive has the characteristic of fast response, this configuration can make the equipment more rapid and efficient in the detection process. The independent drive structure allows for targeted operation during maintenance and expansion, reducing the difficulty and cost of maintenance, and also facilitating the upgrading and expansion of the equipment as needed.

[0041] The first drive rod 212 includes a first rotating rod 2121 and a first displacement rod 2122. The first displacement rod 2122 is mounted on the first rotating rod 2121 and is perpendicular to the first rotating rod 2121. The first displacement rod 2122 rotates with the first rotating rod 2121. The first rotating rod 2121 is controlled to rotate by the first drive motor 211.

[0042] The second drive rod 222 includes a second rotating rod 2221 and a second displacement rod 2222. The second displacement rod 2222 is mounted on the second rotating rod 2221 and is perpendicular to the second rotating rod 2221. The second displacement rod 2222 rotates with the second rotating rod 2221. The second rotating rod 2221 is controlled to rotate by the second drive motor 221.

[0043] By adopting the above technical solution, when the first rotating rod 2121 is controlled to rotate by the first drive motor 211, the first displacement rod 2122 will follow it to rotate, thereby achieving adsorption and manipulation of the washing machine door cover in a certain direction; similarly, when the second rotating rod 2221 is controlled to rotate by the second drive motor 221, the second displacement rod 2222 will also rotate accordingly to achieve manipulation of the washing machine door cover in another direction. The independent and mutually cooperating movement mode helps to improve the working efficiency and accuracy of the equipment. The drive rod configuration composed of the rotating rod and the displacement rod has the advantages of realizing multi-dimensional movement, enhancing stability, improving working efficiency, optimizing space utilization, facilitating maintenance and adjustment, and modular design, which helps to improve the overall performance and use effect of the washing machine door cover qualification detection equipment.

[0044] The first displacement rod 2122 includes a first lead screw 21221 and a first slider 21222. The first slider 21222 is mounted on the first lead screw 21221 and slides along the direction of the first displacement rod 2122. The first connecting rod 311 is connected to the first slider 21222.

[0045] The second displacement rod 2222 includes a second lead screw 22221 and a second slider 22222. The second slider 22222 is mounted on the second lead screw 22221 and slides along the direction of the second displacement rod 2222. The second connecting rod 321 is connected to the second slider 22222.

[0046] By adopting the above technical solution, when the first slider 21222 slides on the first lead screw 21221, it drives the first connecting rod 311 to perform corresponding movements, thereby achieving precise control and positioning of the first suction door device 31; similarly, the sliding movement of the second slider 22222 on the second lead screw 22221 will drive the second connecting rod 321 to move, thereby achieving precise control of the second suction door device 32. This independent yet coordinated movement method helps to improve the working accuracy and efficiency of the equipment.

[0047] A drive cylinder 4 is connected and installed on both the first slider 21222 and the second slider 22222 to drive the first slider 21222 and the second slider 22222 to move on the first lead screw 21221 and the second lead screw 22221.

[0048] A monitoring camera 4 is mounted on the mounting bracket 12, and the monitoring camera 4 is mounted on the upper front side of the mounting bracket 12.

[0049] By adopting the above technical solution, and by monitoring the images captured by camera 4 in real time, problems or abnormalities that may occur in the washing machine door cover during operation can be detected in a timely manner and dealt with promptly. Monitoring camera 4 can provide high-resolution image data, which helps to more accurately detect and evaluate the quality and qualification of the washing machine door cover.

[0050] Both ends of the first rotating rod 2121 and the second rotating rod 2221 are provided with L-shaped steel 5 to increase the rotation range of the first rotating rod 2121 and the second rotating rod 2221.

[0051] By adopting the above technical solution and adding L-shaped steel 5, the structural stability of the first rotating rod 2121 and the second rotating rod 2221 can be enhanced, reducing swaying or deviation during rotation, and improving the stability and working accuracy of the equipment. The design of L-shaped steel 5 can expand the rotation range of the first rotating rod 2121 and the second rotating rod 2221, enabling the equipment to cover a wider working area and adapt to washing machine door covers of different sizes and positions. Through the supporting role of L-shaped steel 5, space resources can be better utilized, allowing the equipment to achieve a greater range of motion and working efficiency within a limited space.

[0052] In practical implementation, the washing machine is first placed within the working range of the fixed frame 12. When the product being tested is a top-opening washing machine, the first drive motor 211 rotates the first rotating rod 2121 of the first suction door device 31 to make the first displacement rod 2122 parallel to the washing machine door. The drive cylinder 4 drives the first slider 21222 to move on the first lead screw 21221, moving the first connecting rod 311 to move the first suction cup 312 to the center of the door and adsorbing it onto the door. The first drive motor 211 is then started to perform an opening / closing test on the door. When the product being tested is a front-opening washing machine, the second drive motor 221 rotates the second rotating rod 2221 of the second suction door device 32 to make the second displacement rod 2222 parallel to the washing machine door. The drive cylinder 4 drives the second slider 22222 to move on the second lead screw 22221, moving the second connecting rod 321 to move the second suction cup 322 to the center of the door and adsorbing it onto the door. The second drive motor 221 is then started to perform an opening / closing test on the door.
