The clamping assembly 5 includes a connecting rod 51, one end of the connecting rod 51 is mounted on the outer wall of the support shaft frame 3, and the other end of the connecting rod 51 is mounted with a clamping block 52. The clamping block 52 is provided with a placement cavity 501. The clamping block 52 is provided with limit members 53 on both sides of the placement cavity 501. The outer wall of the clamping block 52 is embedded with a sealing ring 54.

[0036] The electric telescopic rod 6 is fixedly mounted at the bottom end of the water tank 11 and electrically connected to the main controller 2. The telescopic end of the electric telescopic rod 6 extends into the water tank 11 and is fixedly mounted with a sealing cylinder 61. A pressure sensor 62 is embedded on one side of the bottom end of the sealing cylinder 61. The pressure sensor 62 is electrically connected to the main controller 2. The inner diameter of the sealing cylinder 61 is equal to the outer diameter of the clamping block 52.

[0037] The unloading mechanism 7 is installed on one side of the water tank 11.

[0039] It should be noted that: when in use, by pressing the inclined wedge block 532, the entire sliding frame 533 is driven to slide backward along the slide groove 502, and then the watch body is placed in the placement cavity 501 opened by the clamping block 52, and the inclined wedge block 532 is released. Under the spring force of the limit spring 535, the sliding frame 533 is driven to reset, thereby pulling the pressure roller 534 to the top of the watch body, completing the clamping of the watch. After the watch bodies are clamped in several clamping assemblies 5, the servo motor 4 is started to drive the support shaft frame 3 to rotate in the water tank 11, thereby realizing dynamic waterproof detection. After the detection, the servo motor 4 is controlled to rotate. Drive several clamping components 5 to pass through the sealing cylinder 61 one by one. When passing, control the electric telescopic rod 6 to drive the sealing cylinder 61 to move upward until the sealing cylinder 61 is plugged into the clamping block 52 and sealed with the sealing ring 54. After sealing, as the sealing cylinder 61 continues to rise, the internal water pressure also rises synchronously, thereby realizing pressurization detection. The water pressure is monitored by the pressure sensor 62 throughout the process, and the data is transmitted to the main controller 2. The main controller 2 controls the electric telescopic rod 6 to rise to the height corresponding to the set water pressure to complete the pressurization detection. After the detection, it is rotated to the unloading mechanism 7, and the unloading mechanism 7 is used for automatic unloading.

[0042] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The unloading mechanism 7 includes a side plate 71, which is mounted on one side of the water tank 11, and an electric rod 72 is mounted on the side plate 71, and a base 73 is fixedly mounted on the telescopic end of the electric rod 72, and a micro air pump 74 is mounted on the base 73. The air inlet end of the micro air pump 74 is connected to a rectangular tube 75, which is fixedly mounted on the base 73, and a vacuum suction cup 76 is mounted on the end of the rectangular tube 75 away from the micro air pump 74, and a U-shaped frame 77 is slidably mounted on the rectangular tube 75, and an extrusion spring 78 is sleeved on the rectangular tube 75, one end of the extrusion spring 78 is fixedly connected to the U-shaped frame 77, and the other end of the extrusion spring 78 is fixedly connected to the side wall of the rectangular tube 75, and the two vertical plates of the U-shaped frame 77 are provided with inclined surfaces that contact and cooperate with the oblique wedge block 532;

[0043] It should be noted that when the blanking mechanism 7 is in use, after the clamping assembly 5 rotates with the watch body to one side of the blanking mechanism 7, the electric rod 72 is started to drive the machine base 73 close to the clamping assembly 5. When approaching, the U-shaped frame 77 on the rectangular tube 75 is squeezed by the squeezing spring 78, and the inclined surfaces on its two vertical plates come into contact with the inclined wedge block 532. Then, the squeezing continues to move closer, pushing the inclined wedge block 532 to move backward, thereby driving the sliding frame 533 and the pressure roller 534 to move backward, releasing the pressure limit on the watch body, and then starting the micro air pump 74 to use the vacuum suction cup 76 to suck the watch body. Then, the electric rod 72 is controlled to drive the machine base 73 away from the clamping assembly 5, and the watch body is taken out of the placement cavity 501 until it moves above the guide rack 79. The micro air pump 74 is turned off, and the watch body automatically falls into the guide rack 79.

[0044] In this embodiment, the unloading mechanism 7 also includes a guide rack 79 installed on one side of the water tank 11. A plurality of drainage holes are provided on the bottom plate of the guide rack 79. A return liquid tank 12 is installed at the bottom end of the guide rack 79.

[0046] It should be noted that when the watch body falls onto the guide rack 79, a baffle is provided at the bottom and then the fan 9 is started to dry it, which is convenient for later transportation.

[0047] The working principle of the children's watch waterproof performance tester provided by the utility model is as follows:

[0048] When in use, by pressing the inclined wedge block 532, the entire sliding frame 533 slides backward along the slide groove 502, and then the watch body is placed in the placement cavity 501 opened by the clamping block 52, and the inclined wedge block 532 is released. Under the spring force of the limit spring 535, the sliding frame 533 is driven to reset, thereby pulling the pressure roller 534 to the top of the watch body, completing the clamping of the watch. After several clamping assemblies 5 are clamped with watch bodies, the servo motor 4 is started to drive the support shaft frame 3 to rotate in the water tank 11, thereby realizing dynamic waterproof detection. After the detection, the servo motor 4 is controlled to drive several Each clamping assembly 5 passes through the sealing cylinder 61 one by one. When passing through, the electric telescopic rod 6 is controlled to drive the sealing cylinder 61 to move upward until the sealing cylinder 61 is plugged into the clamping block 52 and sealed with the sealing ring 54. After sealing, as the sealing cylinder 61 continues to rise, the internal water pressure also rises synchronously, thereby realizing pressurization detection. The water pressure is monitored by the pressure sensor 62 throughout the process and the data is transmitted to the main controller 2. The main controller 2 controls the electric telescopic rod 6 to rise to the height corresponding to the set water pressure to complete the pressurization detection. After the detection, it is rotated to the unloading mechanism 7, and the unloading mechanism 7 is used for automatic unloading;

[0049] When the unloading mechanism 7 is in use, after the clamping assembly 5 rotates with the watch body to one side of the unloading mechanism 7, the electric rod 72 is started to drive the machine base 73 close to the clamping assembly 5. When approaching, the U-shaped frame 77 on the rectangular tube 75 is squeezed by the squeezing spring 78, and the inclined surfaces on its two vertical plates contact the inclined wedge block 532, and then continue to approach and squeeze, pushing the inclined wedge block 532 to move backward, thereby driving the sliding frame 533 and the pressure roller 534 to move backward, releasing the pressure limit on the watch body, and then starting the micro air pump 74 to use the vacuum suction cup 76 to suck the watch body, and then control the electric rod 72 to drive the machine base 73 away from the clamping assembly 5, and take the watch body out of the placement cavity 501 until it moves to the top of the guide rack 79, and the micro air pump 74 is turned off, and the watch body automatically falls into the guide rack 79, which is convenient for automatic unloading.
