Description

Technical Field

[0001] The invention relates to the technical field of furniture testing, and in particular to a cabinet door sealing structure testing device and a testing method. Background Art

[0002] In modern home life, people's requirements for the quality of home products are constantly increasing. For furniture such as wardrobes and cabinets, the sealing of the cabinet doors directly affects the storage environment of the internal items. In the humid southern regions, if the wardrobe cabinet doors are not sealed well, moisture can easily enter, causing the clothes to mold. In order to meet consumers' demand for furniture moisture-proof, insect-proof, dust-proof and other functions, furniture manufacturers need to ensure the effectiveness of the cabinet door sealing structure, which has prompted the development of cabinet door sealing structure testing technology. The diversification of home products has also increased the demand for cabinet door sealing structure testing. From traditional wooden cabinet doors to modern glass and metal cabinet doors, cabinet door sealing is an important indicator to measure furniture quality. Good sealing reflects the fineness of furniture manufacturing technology. In the high-end furniture market, consumers have extremely high requirements for furniture quality. Cabinet doors with good sealing can increase the beauty and practicality of furniture and enhance the overall value of furniture. From the perspective of furniture design, cabinet door sealing is also a key factor in realizing the overall design function. For example, moisture-proof and insect-proof storage furniture can only achieve its original design intention if the cabinet door is well sealed. Therefore, cabinet doors with different sealing structures require corresponding testing technology to evaluate their sealing performance;

[0003] In the prior art, the tactile and visual inspections in the intuitive inspection method used in the cabinet door sealing structure test rely on the subjective judgment of the inspector. The difference in such subjective judgment will lead to inconsistency in the test results and fail to provide quantitative data on the degree of sealing. In addition, among the existing physical testing methods, the pressure difference test method is destructive to the finished furniture, and the smoke test method causes odor and damage to the paint surface of the inner wall of the furniture, which limits its ability to effectively test the sealing of the cabinet door.

The gas capture sensor 515 identifies the type of gas. Once the gas is detected, the gas capture sensor 515 will collect information such as the gas concentration and the time when the gas is detected, and send the data to the controller 7. The controller 7 receives the data from the gas capture sensor 51 5 after the gas data is sent is converted into a numerical format that can be calculated and analyzed. At the same time, the controller 7 checks whether there is any error in the data transmission process. If the error data is found, it is marked or requested to be retransmitted. The controller 7 determines the leakage degree of the workpiece based on the received gas concentration data. Assuming that in a standard test environment, for a completely sealed workpiece, the gas capture sensor 515 cannot detect any leaked gas, that is, the gas concentration is zero, but if a certain concentration of gas is detected, the algorithm will determine the severity of the leakage based on the preset concentration-leakage degree relationship curve. The controller 7 combines the position information of the air intake head 514 and the gas diffusion model. When the air intake head 514 detects a higher concentration of gas in a certain direction, the algorithm will infer the source position of the gas, that is, the leakage position, based on the direction and speed model of gas diffusion. ;

[0034] Step 2: The second electric door 24 is opened to allow the telescopic conveyor belt 25 to extend from the inner cavity of the detection mechanism housing 21 to the inner rear of the truss handling robot arm 1. The truss handling robot arm 1 clamps the workpiece and carries it to the surface of the telescopic conveyor belt 25. The telescopic conveyor belt 25 is shortened to move the workpiece to the inner cavity of the detection mechanism housing 21. The second electric door 24 closes the outer portion of the detection mechanism housing 21 again, and the telescopic conveyor belt 25 moves the workpiece to the surface of the roller disc 58.

[0036] Step 4: The robot arm 31 drives the first clamping module 32 to move the internal release unit 4 to the bottom of the gas injection device 26, so that the docking joint 412 in the internal release unit 4 is connected to the gas injection device 26, and the gas supply device 9 injects the internally stored detection gas into the second air pump 411 through the docking joint 412. The second air pump 411 pressurizes the gas and injects it into the gas storage bottle 48 for storage. The wireless chargers 33 on the left and right sides charge the battery module 46 by contacting the charging receiver 42.

[0037] The second electric telescopic rod 63 drives the rotating frame 62 to rotate backward inside the fixed frame 61, and the second clamping module 612 moves to the outer position of the workpiece cabinet door handle and clamps it. The inner side of the bracket 613 contacts the outer side of the workpiece cabinet door handle, and the second motor 68 drives the rotating rod 69 to rotate circumferentially, and drives one end of the connecting rod 67 to move circumferentially with the cooperation of the spring telescopic rod 610, so that the other end of the connecting rod 67 drives the connecting shaft 66 to rotate inside the mounting seat 65, and the connecting shaft 66 drives the driven rod 611 to drive the second clamping module 612 and the bracket 613 to rotate downward, and then the workpiece cabinet door handle is pressed down to release the lock under the cooperation of the second clamping module 612 and the bracket 613, and the third electric telescopic rod 63 shortens and drives the rotating frame 62 to rotate forward inside the fixed frame 61, and then the workpiece cabinet door is flipped outward to open it under the cooperation of the second clamping module 612 and the bracket 613;
