Embodiment
Air-tightness detection method of the present invention is at first tested container to be put into pick-up unit, and is fixed in the pick-up unit after making it and injection section linking to each other; Then, with the pick-up unit sealing, and inject water to keeping a less air chamber that links to each other with the pressure detecting portion branch; Again by injection section to detected container injecting compressed air; By the pressure detection part air chamber pressure is detected; Increase then detected container gas leakage as pressure; As not increasing, represent that then detected container air-tightness is good.The detected air chamber pressure signal in aforementioned pressure test section can reach control section; As the detected container gas leakage of the signal indicating that reaches control section, then the camera part on the may command pick-up unit is partly taken pictures to the gas leakage of detected container; So that detected container is handled.
Seeing accompanying drawing 1,2, is that the present invention is used for the bubble-tight device of detection receptacle; This pick-up unit mainly includes water vat 7, pressing plate 5, water inlet 11, cylinder 15, clamp lever 12, anchor clamps 8, level sensor 6, pressure transducer 16, gas-holder 1 air intake opening 4; Water vat 7 loam cakes are established pressing plate 5, and seal by 13 pairs of these coupling parts of O-ring seal.
Pressing plate 5 is provided with clamp lever 12 and anchor clamps 8 towards the inboard of water vat 7; Clamp lever 8 is L-shaped substantially, and its middle part is connected with in pressing plate 5 inboards, and an end of clamp lever 12 links to each other with the cylinder 15 in pressing plate 5 outsides, and the other end and anchor clamps 8 are provided with in opposite directions; For keeping the impermeability of water vat 7, between cylinder 15 and pressing plate 5, seal by sealing ring 14.Aforementioned clamped lever 12 need be greater than the length of tested container 10, so that tested container 10 is fixed in the water vat 7 with the distance of anchor clamps 8.When tested container 10 being clamped between clamp lever 12 and the anchor clamps 8, establish sealing gasket 9 at the anchor clamps 8 and the opening part pad of tested container 10, so that anchor clamps 8 and tested container 10 are tightly connected.
And anchor clamps 8 are communicated with the air intake opening 4 in pressing plate 5 outsides, and air intake opening 4 is communicated with gas-holder 1 by air inlet pipeline 3; In addition, also be provided with a level sensor 6 on pressing plate 5, the part that level sensor 6 exposes to pressing plate 5 outsides is connected with pressure transducer 16, and pressure transducer 16 can be connected with control section.Be the security that ensures that tested container 10 produces a large amount of bubbles when seriously leaking, level sensor 6 is connected with safety valve 18, and gas-holder 1 also is connected with two-position three-way valve 2; If hypertonia in the air chamber can be by safety valve 18 and two-position three-way valve 2 venting.
And getting off, so that follow-up operation for ease of leakage partial record with tested container 10; Water vat 7 also can be provided with camera 19, between camera 19 and water vat 7 inboards transparent glass 20 is set; When tested container take place to leak, can be by 19 pairs of leakage positions of camera record of making a video recording.
This novel airtight test device adopts PLC control according to the principle of electromechanical integration; At first utilize mechanical arm that the tested container on the production line 10 is grasped, promote piston drive clamp lever 12 by cylinder 15 then and under the cooperation of anchor clamps 8, clamp tested container 10, whole device is put into water vat 7, and with water vat 7 sealings.Inject water by water inlet 11 for 7 li to water vat, water level is elevated to 17 mouthfuls of air chambers, sends signal by level sensor 6 and gives controller, and controller cuts out water inlet 17; Controller control gas-holder 1 injecting compressed air in the tested container 10 then, and by the pressure that pressure transducer 16 is measured in the air chambers, follow PLC and accept pressure signal, judge whether occur bubble in the water, thereby whether the sealing of judging tested container 10 is qualified; If defective, PLC sends signal to camera, is taken pictures by 19 pairs of substandard products of camera.Because tested container 10 may leak seriously, behind the feeding pressurized air, may produce a large amount of bubbles, for this kind situation, this device adds safety valve 18 and two-position three-way valve 2, if hypertonia in the air chamber 7 is opened two valves venting.Camera 19 is installed in water vat 7 walls, and whole water vat 7 usefulness metal materials are made, and perforate is used to install camera 19 in water vat 7, and inwall is equipped with two blocks of glass 20 and is used for taking.
