[0095] Wherein, the first weighing component 2, the first pressure water tank and the wiping device, and the first visual inspection device are arranged along the conveying direction of the conveyor belt 1;

[0096] The conveyor belt 1 is used to transport the product to be tested, and the first weighing component 2 is used to perform initial weighing on the product;

[0097] The first pressure water tank and wiping device includes a pressure water tank assembly 3, a first manipulator and a wiping assembly 4;

[0099] Specifically, the first manipulator and the second manipulator in this embodiment are both manipulators capable of multi-axis movement.

[0100] In the product airtightness detection line of this embodiment, the conveyor belt 1 transports the product. When the product moves to the first weighing component 2, the first manipulator grabs the product into the first weighing component 2. The first weighing component 2 weighs the product to obtain the initial weight W1 of the product. Then, the first manipulator grabs the product into the pressure water tank component 3. After the product is completely immersed in the pressure water tank component 3, the first manipulator grabs the product into the wiping component 4. The wiping component 4 wipes the water on the surface of the product. After wiping, the first manipulator places the product on the conveyor belt 1. The conveyor belt 1 carries the product. After being transported to the first visual inspection device, the second manipulator grabs the product into the blowing component 5, and the blowing component 5 blows away the moisture remaining in the gap of the product. Then, the second manipulator grabs the product into the drying component 6, and the drying component 6 dries the product. Then, the second manipulator grabs the product into the second weighing component 8 for weighing to obtain the weight W2 of the product. At this time, according to the comparison of the results of W1 and W2, it can be judged from the weight whether the air tightness of the product meets the requirements, because if the air tightness of the product is not good, water will enter the inside of the product, and W2 will be too large at this time. After the weighing is completed, the second manipulator places the product into the CCD detection component 7 for visual inspection, and it can be judged from the image that the air tightness of the product meets the requirements. Finally, the second manipulator grabs the product onto the conveyor belt 1 to complete the unloading operation. In the above design, the entire detection process does not require manual intervention, and the entire process is completed automatically, which effectively improves the efficiency of product air tightness detection.

In the above design, the water tank can automatically complete the opening and closing of the box cover 303, and the pressure proportional valve 304 can be used to automatically adjust the air pressure in the box body 302, which effectively improves the automation of the pressure water tank assembly 3 and can meet the air tightness detection work of large quantities of products.

[0191] The structures of the second pressure water tank and the wiping device are the same as those of the first pressure water tank and the wiping device, and the structures of the first visual inspection device and the second visual inspection device are the same.

[0192] It should be noted that after the product passes through the first pressure water tank and wiping equipment and the first visual inspection equipment, the product is transported in sequence by the conveyor line to the second pressure water tank and wiping equipment and the second visual inspection equipment. The product needs to go through the processes of immersion, wiping, blowing, drying, weighing, and visual inspection for a second air tightness test to ensure that the air tightness of the product meets the standards.

[0193] Preferably, the test pressure of the pressure water tank assembly 3 during the first air tightness test is different from the test pressure of the pressure water tank assembly 3 during the second air tightness test, so that the product can meet different air tightness standards.
