[0022] Example: See Figure 1-3The high-precision intelligent air tightness detection test machine shown in the figure includes a base plate 1, which is characterized in that: a sealed box 101 is fixedly connected to the top of the base plate 1, an air duct 3 is fixedly connected to the right side of the sealed box 101, an exhaust fan 301 is fixedly installed on the left side of the air duct 3, a control valve 302 is fixedly installed in the middle of the air duct 3, and a pressure gauge 303 is fixedly installed on the right side of the air duct 3. The inside of the sealed box 101 is connected to a pick-and-place component 2, and the pick-and-place component 2 includes a fixed connection to the left and right sides of the sealed box 101. There are two groups of fixed blocks 201 on the inner wall of the side, and the surfaces of the two groups of fixed blocks 201 are rotatably connected with screw rods 202, and the bottoms of the two screw rods 202 are fixedly connected with transmission sprockets 203, and a toothed chain 204 is arranged between the two transmission sprockets 203. The surfaces of the two screw rods 202 are threadedly sleeved with movable blocks 205, and a lifting plate 206 is fixedly connected between the two movable blocks 205. A motor 207 is installed on the left side of the bottom of the sealing box 101, and the output end of the motor 207 is fixedly connected with a rotating shaft 208 , the connection between the rotating shaft 208 and the left screw rod 202 is a fixed connection; when in use, the operator turns on the motor 207 to drive the rotating shaft 208 to rotate, and at the same time, the transmission sprocket 203 and the toothed chain 204 cooperate to drive the two screw rods 202 to drive, and further drive the movable block 205 to drive, thereby driving the lifting plate 206 to lift and adjust, and driving the inspection piece to lift and lower. The operator does not need to put his hand into the test machine cavity to take and place the inspection piece, which is convenient for the operator to take and place the inspection piece and improves the inspection efficiency. During the test, the operator turns on the exhaust fan 301 to discharge the gas in the sealing box 101 through the air guide pipe 3, and then closes the control valve 302, and records the reading on the barometer 303. After standing for a period of time, if the reading on the barometer 303 remains unchanged, the sealing of the inspection piece is good. If the reading on the barometer 303 changes, it means that there is a problem with the sealing of the inspection piece, causing the air inside the inspection piece to escape, changing the air pressure in the sealing cover, and the sealing of the inspection piece is unqualified. In this embodiment, refer to Figure 1 and 2 As shown, a vertical plate 102 is fixedly connected to the rear top of the bottom plate 1, a connecting plate 103 is fixedly connected to the top of the front end of the vertical plate 102, a hydraulic cylinder 104 is installed on the top of the connecting plate 103, an output end of the hydraulic cylinder 104 is transmission-connected to a telescopic rod 105, and a bottom end of the telescopic rod 105 is fixedly connected to a box cover 106; when in use, an operator drives the telescopic rod 105 to extend and retract by turning on the hydraulic cylinder 104, and controls the opening and closing of the box cover 106. When the telescopic rod 105 is extended, the box cover 106 falls on the sealed box 101 to seal the sealed box 101, and when the telescopic rod 105 is retracted, the box cover 106 opens.

[0023] In this embodiment, refer to Figure 1 and 2As shown, a sealing groove 108 is provided on the top surface of the sealed box 101, and the sealing groove 108 is arranged in a "mouth" shape. A sealing block 107 is fixedly connected to the bottom end of the box cover 106, and the size and shape of the sealing block 107 are adapted to the sealing groove 108. When in use, the sealing block 107 and the sealing groove 108 cooperate to close the box cover 106 and the sealed box 101, thereby ensuring the airtightness inside the sealed box 101.

[0024] In this embodiment, refer to Figure 2 and 3 As shown, the two screw rods 202 are both arranged longitudinally and in parallel; when in use, the two screw rods 202 cooperate to drive the movable block 205 to transmit simultaneously, so that the lifting and lowering of the lifting plate 206 is more stable.

[0025] In this embodiment, refer to Figure 2 and 3 As shown, the two transmission sprockets 203 are meshed with the toothed chain 204; when in use, the toothed chain 204 drives the two transmission sprockets 203 to rotate simultaneously.

[0026] Working principle: When in use, the operator places the detection part on the lifting plate 206, turns on the motor 207 to drive the rotating shaft 208 to rotate, and at the same time, the transmission sprocket 203 and the toothed chain 204 cooperate to drive the two screw rods 202 to drive, and further drive the movable block 205 to drive, thereby driving the lifting plate 206 to descend, and then the hydraulic cylinder 104 is opened to work the telescopic rod 105 to extend, and the box cover 106 falls on the sealed box 101 to seal the sealed box 101, and then the exhaust fan 301 is turned on to exhaust the gas in the sealed box 101 through the guide The air pipe 3 is discharged, and then the control valve 302 is closed, and the reading on the pressure gauge 303 is recorded. After standing for a period of time, if the reading on the pressure gauge 303 does not change, the sealing of the test piece is good. If the reading on the pressure gauge 303 changes, it means that there is a problem with the sealing of the test piece, causing the air inside the test piece to escape, changing the air pressure in the sealing cover, and the sealing of the test piece is unqualified. After the test is completed, the telescopic rod 105 is retracted, the box cover 106 is opened, and then the motor 207 is turned on to drive the lifting plate 206 to rise, and the test piece is taken out.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
