Description

Technical Field

[0001] The utility model relates to the technical field of automated detection, in particular to a product air tightness detection line. Background Art

[0002] In the existing technology, in order to ensure the air tightness of the product, the product needs to be tested for air tightness before leaving the factory. At present, the common air tightness test operation is as follows: place the product in a water tank with a certain pressure, take it out after a period of time, wipe the surface of the product dry, transfer the product to a water blowing device to blow away the moisture, and then place the product in a drying device for drying. Finally, transfer the product to a visual inspection device for inspection to determine whether there is water vapor entering the product, thereby determining whether the air tightness of the product meets the requirements.

[0003] In the above-mentioned tests, each device is set up separately, and there is no continuous test line between them. Under this design, it is necessary to rely on manual transportation to transfer products from different devices. The transfer process takes a lot of time, which seriously affects the efficiency of product air tightness testing.

[0092] The utility model discloses a product air tightness detection line for solving the technical problem of low product air tightness detection efficiency.

[0093] In order to make the personnel in the technical field better understand the utility model scheme, the utility model is further explained in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of the utility model protection.

[0094] Please refer to Figures 1 to 19 The utility model embodiment provides a product air tightness detection line, including conveying belt 1, first weighing assembly 2, first pressure water tank and wiping equipment and first visual inspection equipment;

[0095] Among them, first weighing assembly 2, first pressure water tank and wiping equipment, first visual inspection equipment are along the conveying direction of conveying belt 1 and set up;

[0096] Conveying belt 1 is used for transporting the product to be detected, and first weighing assembly 2 is used for weighing the product initially.

[0097] First pressure water tank and wiping equipment include pressure water tank subassembly 3, first manipulator and wiping subassembly 4.

[0099] Specifically, the first manipulator and the second manipulator in the embodiment are multi-axis movable manipulators.

[0100] In the product airtightness detection line of the embodiment, the conveying belt 1 transports the product. When the product moves to the first weighing assembly 2, the first mechanical hand grabs the product into the first weighing assembly 2. The first weighing assembly 2 weighs the product to obtain the initial weight W1 of the product. Then, the first mechanical hand grabs the product into the pressure water tank assembly 3. After the product is immersed in the pressure water tank assembly 3, the first mechanical hand grabs the product into the wiping assembly 4. The wiping assembly 4 wipes the water on the surface of the product. After wiping, the first mechanical hand places the product on the conveying belt 1. The conveying belt 1 transports the product into the first visual detection equipment. The second mechanical hand grabs the product into the air blowing assembly 5. The air blowing assembly 5 blows away the water remaining in the gap of the product. Then, the second mechanical hand grabs the product into the drying assembly 6 to perform drying treatment. Then, the second mechanical hand grabs the product into the second weighing assembly 8 to perform weighing and obtain the weight W2 of the product. At this time, the airtightness of the product can be judged from the weight according to the comparison of W1 and W2. If the airtightness of the product is not good, water will enter the product. At this time, W2 will be larger. After the weighing is completed, the second mechanical hand places the product into the CCD detection assembly 7 to perform visual detection. The airtightness of the product can be judged from the image. Finally, the second mechanical hand grabs the product onto the conveying belt 1 to complete the discharging operation. In the above design, the whole detection process does not need manual intervention and is automatically completed, which effectively improves the efficiency of the product airtightness detection.

[0101] Further, as shown in Figures 3 to 9 The pressure water tank assembly 3 in the embodiment includes a first rack 301, a tank body 302 for loading water, and a tank cover 303 for covering the top opening of the tank body 302.

[0104] The tank body 302 is installed with a lifting assembly. The lifting assembly is connected with a tray 314. The tray 314 is provided with a positioning cavity for placing the product.

[0105] In addition, the tank cover 303 is also installed with a pressure sensor 313. The pressure sensor 313 is used to detect the air pressure in the tank body 302.

[0106] Specifically, the air source in the embodiment is specifically a gas storage tank.

[0107] In the pressure tank assembly 3 of the embodiment, after the first mechanical arm places the product on the tray 314, the lifting assembly drives the tray 314 to move downward so that the product is soaked in water, then the tank cover 303 is automatically closed on the top opening of the tank body 302 under the drive of the first lifting cylinder 307, and after the product is soaked, the tank cover 303 is separated from the tank body 302 under the drive of the first lifting cylinder 307, the lifting assembly drives the tray 314 to rise so that the product is out of the water surface, and the air pressure in the tank body 302 can be automatically adjusted by adjusting the pressure proportional valve 304 on the air pipe, so that the product can be soaked in water under different pressure environments. In the above design, the tank cover 303 can automatically complete the opening and closing action, and the air pressure in the tank body 302 can be automatically adjusted by the pressure proportional valve 304, which effectively improves the automation degree of the pressure tank assembly 3 and can meet the air tightness detection work of large quantities of products.

[0117] It should be noted that through the above design, the box cover 303 can be completely locked on the box body 302, ensuring the tightness of the connection between the box cover 303 and the box body 302, and ensuring that the product can be soaked in a closed environment.

[0192] It should be noted that, after the product passes through the first pressure water tank and wiping device and the first visual detection device, the product is continuously transported to the second pressure water tank and wiping device and the second visual detection device by the conveying line, and the product needs to pass through the processes of water immersion, wiping, air blowing, drying, weighing, and visual detection again for the second air tightness detection, so as to ensure that the air tightness of the product meets the standard.

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