Description

Technical Field

[0001] This utility model relates to the technical field of water purifier sealing test, and in particular to a whole-machine air detection device. Background Technology

[0002] In the manufacturing process of water purifiers, sealing testing is a crucial step in ensuring product quality. Traditionally, companies often use water flow testing to check the sealing of water purifiers. However, this testing method has many drawbacks, such as requiring a large area to set up the testing equipment and water source; long testing time, from filling with water to observing for leaks, the entire process is time-consuming; serious problems with residual water in the machine, as the water left inside the equipment after testing is difficult to clean, easily breeding bacteria, leading to excessive bacterial colonies and affecting the subsequent production environment; and the need to clean the residual water after each test, increasing the number of operational steps and workload.

[0003] With the continuous development of technology, ventilation testing has gradually become the mainstream method. Ventilation testing has advantages such as small footprint and fast testing speed. However, during the ventilation testing process, how to efficiently and quickly block all the inlet and outlet ports of the water purifier while ensuring the continuity of the air path has become a new technical challenge. Currently, many companies use manual installation of special air testing filter cartridges and manual insertion and removal of pipes to achieve air testing. This method is not only inefficient but also time-consuming. Because manual operation is limited in speed, and the machine can only continue to operate after all operations are completed manually, it seriously affects the efficiency of air testing and cannot meet the needs of modern large-scale production for efficient and rapid testing.

[0019] Figure 1 This is a schematic diagram of the structure of a complete air detection device according to the present invention; Figure 2 This is a schematic diagram of the air circuit board of a complete air detection device according to the present invention, as shown below. Figure 1-2 The diagram illustrates a preferred embodiment of a whole-machine air detection device for performing air detection on a water purifier. It includes: a frame 1, a first drive mechanism 4, and a second drive mechanism 10. The frame 1 is equipped with a turntable 3, a positioning mechanism 2, and at least one air path plate. The air path plate has an air inlet 6 and at least one air outlet 7. The air path plate also has an air inlet pipe 8 communicating with the air inlet 6 and an air outlet pipe 9 communicating with the air outlet 7. The water purifier has a water inlet port and at least one water outlet port. The turntable 3... The first drive mechanism 4 is connected to the turntable 3 to drive the turntable 3 to rotate so that the air inlet 6 and the air outlet 7 are respectively aligned with the water inlet and water outlet positions on the water purifier. The positioning mechanism 2 is located on the side of the turntable 3 to clamp and position the water purifier. The second drive mechanism 10 is connected to the air circuit board to drive the air circuit board to move toward the water purifier so that the air inlet 6 is sealed and inserted into the water inlet position and the air outlet 7 is sealed and inserted into the water outlet position.

[0020] In this application, the automatic air detection of the water purifier is realized through the coordinated operation of the turntable 3, the positioning mechanism 2, the air circuit board and the first and second drive mechanisms 10. This solves the problem of low efficiency caused by manual operation such as manually installing the filter element air detection tool and manually inserting the air inlet and outlet pipes 9. It reduces manual intervention, improves air detection efficiency, and ensures accurate air circuit connection, thereby improving detection accuracy.

[0021] In a preferred embodiment, the compressor is connected to the air inlet pipe 8, and pressure sensors are installed on both the air inlet pipe 8 and the air outlet pipe 9. The water purifier’s sealing performance is determined by comparing whether there is a difference between the air inlet pressure of the air inlet pipe 8 and the air outlet pressure of the air outlet pipe 9.

[0022] More preferably, the air circuit board 5 has a first cavity that connects the air inlet pipe 8 and the air inlet nozzle 6, and a second cavity that connects the air outlet pipe 9 and the air outlet nozzle 7.

[0023] Furthermore, in a preferred embodiment, the positioning mechanism 2 includes a limiting plate 21, two side plates 22, and a driving assembly. The limiting plate 21 is mounted on the frame 1 and located on the side of the turntable 3, used to limit the back of the water purifier. The two side plates 22 are located on both sides of the turntable 3, and the limiting plate 21 is located between the two side plates 22. The driving assembly is connected to the two side plates 22 for driving the two side plates 22 to move closer to each other or further away from each other. By moving the two side plates 22 closer to each other, the two side plates 22 clamp and position the two sides of the water purifier respectively.

[0024] In this application, the positioning mechanism 2 can accurately position the water purifier from multiple directions. The limiting plate 21 limits the back of the water purifier, and the two side plates 22 clamp the two sides of the water purifier under the action of the driving component, ensuring the stability of the water purifier during the air detection process, avoiding the problem of inaccurate detection caused by the position deviation of the water purifier, and improving the reliability of the detection.

[0025] In a more optimized configuration, the limiting plate 21 is mounted on the frame 1 in a sliding adjustment manner. The position of the limiting plate 21 can be adjusted to accommodate the positioning of water purifiers of different sizes.

[0026] Furthermore, in a preferred embodiment, the drive assembly includes two clamping cylinders 24, which are mounted on the frame 1 and are respectively connected to the opposite sides of the two side plates 22. Using clamping cylinders 24 as the drive assembly provides rapid action and stable force, enabling the quick and accurate clamping of the two side plates 22 towards the water purifier. Furthermore, it provides a stable clamping force during the clamping process, ensuring accurate and stable positioning while improving the efficiency of the entire positioning process.

[0027] Furthermore, as a preferred embodiment, the water purifier has two water outlets, namely a clean water outlet and a wastewater outlet, and two corresponding air outlets 7 are provided.

[0028] Furthermore, as a preferred embodiment, the second driving mechanism 10 includes a telescopic cylinder 101. The output end of the telescopic cylinder 101 is connected to the air circuit board 5 for driving the air circuit board 5 to move closer to or further away from the water purifier. The telescopic cylinder 101 can precisely control the movement distance of the air circuit board, ensuring that the air inlet nozzle 6 and the air outlet nozzle 7 can be accurately inserted into the corresponding holes of the water purifier, achieving sealed insertion. This ensures the airtightness of the air circuit during the air test, avoids air leakage caused by inaccurate insertion, and improves the accuracy of the test.

[0029] Furthermore, in a preferred embodiment, the second drive mechanism 10 also includes a lifting frame 102 and an adjustment assembly. The lifting frame 102 is longitudinally adjustable and mounted on the frame 1. A telescopic cylinder 101 is mounted on the lifting frame 102. The adjustment assembly is kinetically connected to the lifting frame 102 and is used to adjust the height of the lifting frame 102. The arrangement of the lifting frame 102 and the adjustment assembly allows the height of the air circuit board to be adjusted according to different models of water purifiers, improving the compatibility of the device and enabling it to adapt to the air detection requirements of water purifiers of different heights. This expands the applicability of the device and reduces the time and cost of readjusting the equipment when replacing different models of water purifiers.

[0030] For a more optimized approach, the adjustment component can be pneumatically adjusted, such as by using a lifting cylinder (not shown in the figure). The lifting cylinder is connected to the lifting frame 102 via a transmission to achieve the lifting of the lifting frame 102. Of course, in some embodiments, the lifting can also be driven by an electric cylinder or a hydraulic cylinder.

[0031] Furthermore, in a preferred embodiment, the first drive mechanism 4 includes a motor mounted on the frame 1 and connected to the bottom of the turntable 3 for driving the turntable 3 to rotate. The motor, as the first drive mechanism 4, features smooth rotation and adjustable speed, enabling precise control of the rotation angle of the turntable 3. This ensures that the air inlet 6 and air outlet 7 accurately correspond to the water inlet and outlet positions on the water purifier, improving the accuracy of air path connection during air testing. Simultaneously, the motor drive method is simple, reliable, and easy to maintain and control.

[0032] In a preferred embodiment, a visual recognition system is used to control the motor rotation angle. For example, a camera is installed on the frame 1 and aimed at the water purifier hole and the air inlet 6 and air outlet 7 of the air circuit board. The image captured by the camera is analyzed by an image recognition algorithm to determine whether the air inlet 6 and air outlet 7 are aligned with the corresponding hole. If the recognition result is that they are aligned, the motor stops rotating. If they are not aligned, the motor rotation angle is adjusted until they are aligned.

[0033] Furthermore, as a preferred embodiment, both the air inlet 6 and the air outlet 7 have chamfered ends. The chamfered ends of the air inlet 6 and the air outlet 7 make insertion into the water purifier's holes smoother, reducing resistance during insertion and preventing potential damage to the water purifier's holes due to sharp ends. This also improves the accuracy and speed of insertion, further enhancing the efficiency of the air detection.

[0034] To further optimize the sealing performance between the outer wall of the air inlet 6 and the inner wall of the water inlet, and between the outer wall of the air outlet 7 and the inner wall of the water outlet, the air inlet 6 and the air outlet 7 are fitted with rubber sleeves or wrapped with PTFE tape.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
