Problems solved by technology

[0003] At present, there are generally two kinds of leak detection methods used to test the sealing performance of the pot body. The first one is to fill a certain amount of water in the pot body and let it stand for a while to observe whether there is water leakage. The cost of this test method is It takes a long time, and the test water needs to be recycled again. The process is relatively time-consuming and cumbersome; the second is to use a specific mold to seal the pot body and fill the inner cavity with gas, let it stand for a period of time and dry it. Observe the change of its air pressure. Although this method has a high degree of automation, it is necessary to make a special sealing jig according to the shape of the inner cavity of the pot in the traditional process, and it is difficult to achieve the connection between the sealing jig and the inner cavity of the pot due to the influence of manufacturing errors. True sealing will inevitably affect the test results, and the above situation is more obvious for glass pots

Embodiment 1

[0026] see figure 1 , the present embodiment provides a kettle body air tightness detection device, the involved kettle body 1 includes a kettle body 11 and a kettle bottom 12, the kettle bottom 12 is fixedly connected to the lower end of the kettle body 11, and the upper end of the kettle body 11 is opened There is a spout 13, and the detection device includes a frame 32, a base 2, a drive assembly 3 and a detection assembly 4, and the detection assembly 4 is installed on the frame 32.

[0027] see figure 1 and figure 2 , the pot body 1 is placed on the base 2 with the spout 13 facing upwards, the driving assembly 3 includes a driving cylinder 31, the driving cylinder 31 is arranged above the base 2 through a frame 32, and the extension of the piston rod 311 is The outgoing direction is toward the lower side, and the detection assembly 4 is installed on the lower end of the piston rod 311. The detection assembly 4 can move up and down relative to the kettle body 1 through ...

Embodiment 2

[0036] see Figure 4 , the difference between the present embodiment and the first embodiment lies in the difference in the arrangement of the base 2, the detection device of the present embodiment also includes a conveying mechanism 6, and the conveying mechanism 6 is provided with a plurality of bases 2 along its conveying direction, each base 2 are placed with pots 1, and the conveying mechanism 6 sequentially transports the pots 1 to be detected on each base 2 to the bottom of the detection assembly 4 for detection of sealing performance. Preferably, the drive assembly 3 and Multiple groups of detection components 4 can be arranged accordingly, so that multiple pot bodies 1 can be detected at one time. The arrangement of the conveying mechanism 6 can improve the degree of automation of the detection device and effectively improve the detection efficiency.

Abstract

The invention relates to the technical field of tightness detection equipment, in particular to a kettle tightness detection device and a detection method employing the same. The kettle tightness detection device comprises a driving component and a detection component; the driving component drives the detection component to move up and down selectively so as to move into or leave an inner cavity of a kettle under detection placed below the detection component; the detection component comprises a support and an airbag in ring shape; the airbag surrounds the lateral side of the support; after being inflated, the airbag may attach to the inner wall of a kettle body; the bottom of the support is provided with a suction port and a vacuum sensor; the airbag is provided with an inflating port; the inflating port is connected with an air source through a first guide pipe; the suction port is connected with a vacuumizing device through a second guide pipe; during detection, the airbag moves down to the inner cavity of the kettle and expands and attaches to the inner wall of the kettle; air between the detection component and the bottom of the kettle is abstracted to increase the pressure toa threshold; tightness of the kettle is judged by detecting changes in the pressure. The detection component is tightly fitted to the kettle, the detection results are precise and reliable, and the kettle tightness detection device is good in practicality and universality.

Description

technical field [0001] The invention relates to the technical field of airtightness testing equipment, in particular to a kettle body airtightness testing device and a testing method. Background technique [0002] Existing electric kettles include a kettle body and a heating base. The kettle body is generally formed by welding or bonding the kettle body and the kettle bottom. When the kettle body is being heated or used, due to the gap between the kettle body and the kettle bottom If the connection is not firm and water leakage occurs, there will be dangers such as electric leakage and burns. Therefore, in the traditional production process, it is necessary to test the tightness of the pot body to ensure that the pot body is tightly connected to the pot body. [0003] At present, there are generally two kinds of leak detection methods used to test the sealing performance of the pot body. The first one is to fill a certain amount of water in the pot body and let it stand for ...
