The clamping device 42 is electrically connected to the controller, and clamps the filter element assembly at the discharge end of the spin welder 30 into the sealed housing 42 under the control of the controller.
The sealing housing 42 is disposed on the working platform 41, and has a hollow cavity for accommodating the filter element assembly to be tested, an air inlet is disposed at the top of the hollow cavity, and an air outlet is disposed at the bottom of the hollow cavity. Sealed housing 42 set up in on work platform 41, have the cavity that holds the filter element group spare that awaits measuring, just sealed housing 42 top have with the filter element group spare water inlet assorted air intake that awaits measuring, the bottom has the air outlet.

The high pressure fan 44 is disposed on the working platform 41, and has an air supply duct 441 leading to an air inlet of the sealing case 42, and the air supply duct 441 is fixedly disposed above the first sealing member 421. The high pressure fan 44 operates under the control of the controller, and delivers high pressure gas to the interior of the filter element assembly to be tested placed in the sealed housing 42 through the air supply pipeline 441, so as to perform air tightness detection on the filter element assembly. Specifically, in order to realize that one detection device can detect two parameters of the filter element assembly and avoid the complication of the production process, the high-pressure fan 44 is provided with a primary wind gear and a secondary wind gear for adjusting wind power; the primary wind gear is weak in wind power and is used for detecting whether the air tightness of the filter element assembly is qualified or not; the secondary wind gear is strong in wind power and used for detecting whether the compressive strength of the filter element assembly meets the production requirements. And when the controller judges that the air tightness test of the filter element is qualified, the gear of the high-pressure fan 44 is adjusted to a second-level wind power gear to test the compressive strength of the filter element. The working principle is as follows: when the impeller rotates, the vane causes the gas to move forward and outward due to centrifugal force, thereby forming a series of helical movements. The air between the impeller blades rotates in a spiral accelerating way and pushes the air outside the pump body into the side groove, and after the air enters the side channel, the air is compressed and then returns to the space between the impeller blades to rotate in an accelerating way again. As the air passes through the impellers and side channels along a helical path 411, each impeller increases in compression and acceleration, and as rotation progresses, the kinetic energy of the air increases, causing the pressure of the air passing through the side channels to increase further. When the air reaches the junction of the side channel and the discharge flange, the air is forced out of the vanes and out of the pump body through the outlet muffler, leading to the supply duct 441.
The wind speed detector 45 is arranged at the air outlet at the bottom of the sealing shell 42 and used for detecting whether the air outlet blows out wind or not so as to detect whether the air tightness test of the filter element assembly to be tested is qualified or not. The wind speed detector 45 adopts a traditional three-cup rotating frame structure, and the working principle is as follows: the wind speed is linearly converted into the rotational speed of the rotating gantry. Specifically, a toothed blade is fixed on a shaft of the rotating frame, when the rotating frame rotates along with wind, the shaft drives the blade to rotate, and the toothed blade continuously cuts a light beam in an optical path of the photoelectric switch, so that the wind speed is linearly converted into an output pulse signal of the photoelectric switch, and the pulse signal is transmitted to the controller; the controller detects that the output end of the photoelectric switch has pulse signal output, and then the air blowing out of the air outlet of the sealing shell can be judged, so that the filter element assembly is judged to be unqualified in air tightness.
The following is described from the working principle of the detection device 40: when the clamping device 42 clamps the filter element assembly to be tested to the fixing frame 423 on the inner wall of the first sealing piece 421 of the sealing shell 42, the controller controls the mechanical arm to suck the plugging piece to plug the water outlet of the filter element assembly, then controls the second sealing piece 422 of the sealing shell 42 to move towards the first sealing piece 421 and form a hollow cavity containing the filter element assembly to be tested together with the first sealing piece 421, seals the filter element assembly in the shell, controls the high-pressure fan 46 to operate, and conveys high-pressure gas to the interior of the filter element assembly through the air supply pipeline 441, at this time, the air speed detector arranged at the air outlet at the bottom of the sealing shell 42 detects whether air blows out, and when no air blows out, the air tightness of the filter element assembly is qualified; when wind blowing is detected, the air tightness of the filter element component is not qualified. And when the air tightness of the filter element assembly is detected to be qualified, adjusting the gear of the high-pressure fan 46 to a second-level wind power gear, and testing the compressive strength of the filter element assembly.
