Through the foregoing solution, the problem that the existing airtight detection device for a deep-hole plate has a fixed position of the placement base when detecting the deep-hole plate, can only place a 96-hole deep-hole plate, cannot place some special oversize or undersize deep-hole plates, and thus cannot perform airtight detection on them, resulting in inconvenient use, is solved.

[0021] For this specific embodiment, the electric push rod 102 is fixedly connected to the detection device main body 101 and is located at the bottom of the detection device main body 101. The sealing member 103 is arranged on one side of the detection device main body 101, and the connecting member 104 is arranged on one side of the sealing member 103. Place the deep-hole plate to be detected on the electric push rod 102 and start the electric push rod 102 to push it to a position close to the sealing member 103. Through the cooperation of the sealing member 103 and the connecting member 104, airtight detection of the deep-hole plate is carried out. The sealing member 103 includes an airtight valve, a barometric pressure detector, a rubber sealing plate, a rotating shaft, a cross bar, and an extrusion screw. The connecting member 104 includes a rubber sealing ring, a vertical rod, and an adjustment screw. Its specific structure and usage method are detailed in the patent with the publication number CN213632584U, which is not the protection scope of this application and will not be elaborated here.

[0022] Among them, the connecting ring 106 is fixedly connected to the output end of the electric push rod 102 and is located at the top of the electric push rod 102, the placement seat 107 is fixedly connected to the connecting ring 106 and is located at the top of the connecting ring 106, the reset spring 108 is fixedly connected to the placement seat 107 and is located on one side of the placement seat 107, the top plate 109 is fixedly connected to the reset spring 108 and is slidably connected to the placement seat 107, the telescopic rod 110 is fixedly connected to the placement seat 107, and the output end of the telescopic rod 110 is fixedly connected to the top plate 109 and is located between the top plate 109 and the placement seat 107, the fixed plate 111 is fixedly connected to the placement seat 107 and is located on the side of the placement seat 107 away from the reset spring 108, according to the size of the deep well plate, the staff compresses the reset spring 108, the reset spring 1 08 drives the top plate 109 to move, so that the top plate 109 is no longer close to the fixing plate 111. At the same time, the return spring 108 is kept stable by the operation of the telescopic rod 110. After the top plate 109 and the fixing plate 111 are separated to a distance suitable for placing the deep-well plate, the staff first puts the deep-well plate into the placement seat 107 and releases the return spring 108. The return spring 108 pushes the top plate 109 to move in the direction of the fixing plate 111 until it contacts the deep-well plate. At this time, the two sides of the deep-well plate are supported by the top plate 109 and the fixing plate 111, thereby fixing the position of the deep-well plate, thereby solving the problem that the existing deep-well plate air tightness detection equipment has a fixed position of the placement base when detecting the deep-well plate, and can only place 96-hole deep-well plates, and cannot place some special deep-well plates that are too large or too small, and thus cannot be subjected to air tightness detection, resulting in inconvenience in use.

[0023] Secondly, the top electric push rod 112 is fixedly connected to the detection device main body 101 and is located on one side of the detection device main body 101. The mounting block 113 is fixedly connected to the output end of the top electric push rod 112 and is located on one side of the top electric push rod 112. The adjusting plate 114 is slidably connected to the mounting block 113, is fixedly connected to the sealing member 103, and is located on the side of the mounting block 113. The positioning bolt 115 is threadedly connected to the adjusting plate 114 and passes through the adjusting plate 114. After the deep hole plate is placed and fixed in the placing seat 107, the position of the adjusting plate 114 on the mounting block 113 can be adjusted according to the position of the deep hole plate. After the position of the adjusting plate 114 is adjusted, the positioning bolt 115 can be rotated clockwise. The positioning bolt 115 passes through the adjusting plate 114 to fix the position of the adjusting plate 114. At this time, the top electric push rod 112 can be started. The output end of the top electric push rod 112 pushes the mounting block 113 to move, and the adjusting plate 114 moves accordingly. The sealing member 103 placed on the adjusting plate 114 moves accordingly, so that the sealing member 103 can contact the deep hole plate on the placing seat 107, and then cooperate with the connecting member 104 to perform airtightness detection on it.

[0024] Thirdly, the blower 116 is fixedly connected to the detection device main body 101 and is located on the top of the detection device main body 101. The air delivery pipe 117 is communicated with the blower 116 and is also communicated with the connecting member 104. When the sealing member 103 contacts the deep hole plate, the blower 116 is started. The blower 116 outputs positive pressure along the air delivery pipe 117, and the air pressure passes through the connecting member 104 and the sealing member 103 to pressurize the deep hole plate. At this time, the airtight valve in the sealing member 103 is closed, and the air pressure detector in the sealing member 103 is used to detect the air pressure of the deep hole plate.

[0025] In addition, the two bottom plates 118 are respectively fixedly connected to the top plate 109 and the fixing plate 111 and are located at the bottoms of the top plate 109 and the fixing plate 111. When placing the deep hole plate, the deep hole plate can be placed on the bottom plates 118 at the bottoms of the top plate 109 and the fixing plate 111, so as to avoid the deep hole plate directly contacting the placing seat 107 and protect the deep hole plate.

[0026] Meanwhile, the sealing ring 119 is fixedly connected to the air delivery pipe 117 and is located on the side of the air delivery pipe 117. The connection parts at both ends of the air delivery pipe 117 are sealed by the sealing ring 119 to prevent air pressure from leaking from the air delivery pipe 117.

[0027] The deep-well plate air-tightness testing device described in this embodiment, when testing the air-tightness of the deep-well plate, first, according to the size of the deep-well plate, the staff compresses the return spring 108, and the return spring 108 drives the top plate 109 to move, so that the top plate 109 is no longer close to the fixing plate 111. At the same time, the return spring 108 is kept stable by the operation of the telescopic rod 110. After the top plate 109 and the fixing plate 111 are separated to a distance suitable for placing the deep-well plate, the staff first puts the deep-well plate into the placement seat 107 and releases the return spring 108. The return spring 108 pushes the top plate 109 to move in the direction of the fixing plate 111 until it contacts the deep-well plate. At this time, the two sides of the deep-well plate are pressed against the top plate 109 and the fixing plate 111, thereby fixing the position of the deep-well plate. After the deep-well plate is placed in the placement seat 107 and fixed, it can be adjusted according to the position of the deep-well plate. The position of the adjusting plate 114 on the mounting block 113 is adjusted. After the position of the adjusting plate 114 is adjusted, the positioning bolt 115 can be right-turned, and the positioning bolt 115 passes through the adjusting plate 114 to fix the position of the adjusting plate 114. At this time, the top electric push rod 112 can be started, and the output end of the top electric push rod 112 pushes the mounting block 113 to move, and the adjusting plate 114 moves accordingly, and the sealing member 103 placed on the adjusting plate 114 moves accordingly, so that the sealing member 103 can contact the deep well plate on the placement seat 107. At the same time, the fan 116 is started, and the fan 116 outputs positive pressure along the air supply pipe 117. The air pressure passes through the connecting member 104 and the sealing member 103 to pressurize the deep well plate. At this time, the air-tight valve in the sealing member 103 is closed, and the air pressure of the deep well plate is detected by the air pressure detector in the sealing member 103.
