Description

Technical Field

[0001] The invention belongs to the technical field of sealing detection, and in particular relates to a sealing detection device for a medical airtight door. Background Art

[0002] Medical airtight doors can effectively isolate the inside and outside of the ward, prevent the spread of harmful substances such as germs and dust, and protect the health of medical staff and other patients; and can maintain the indoor air pressure stable and reduce noise, reduce the impact of external noise and airflow on the room, and provide patients with a quiet and comfortable treatment environment. In order to ensure the sealing performance of the airtight door, the airtightness of the airtight door needs to be tested after the production of the airtight door. For example, an aluminum alloy airtight door airtightness detection device proposed in patent publication number CN217845542U can detect the sealing of the airtight door.

[0003] During the production process of airtight doors, mold defects, unstable processing technology, assembly process errors and other factors may cause leakage in the same area of ​​multiple airtight doors. However, when detecting the sealing of the airtight door, the existing airtight door sealing detection device can only determine whether there is a problem with the overall sealing of the airtight door, and cannot intuitively display the leakage location of the airtight door. This requires the operator to conduct subsequent inspections, thereby increasing the operator's workload.

[0004] In addition, after the airtight door inspection is completed, it is necessary to classify and place it according to its sealing performance. However, the leakage points of some airtight doors are extremely small, and it is difficult for operators to accurately distinguish the quality of the airtight doors with the naked eye. Therefore, in the subsequent classification and placement process, it is easy to confuse good airtight doors with defective airtight doors, which in turn affects the yield rate of the airtight doors.

[0037] The operating principle of the present invention is now described as follows: the produced airtight door 59 to be tested is transported to the testing equipment through the conveyor belt 4. During the process of conveying the airtight door 59 to be tested, the airtight door 59 to be tested will be blocked by the baffle 8, and the airtight door 59 to be tested will squeeze the trigger switch 9 in front of the right baffle 8. After the trigger switch 9 is triggered, the trigger switch 9 will transmit an electric signal to the PLC controller 10. After receiving the electric signal, the PLC controller 10 first controls the conveyor belt 4 to stop working, and then controls the second electric push rods 11 on the left and right sides to work, and drives the correction on both sides through the second electric push rods 11 on the left and right sides. The positive plate 12 moves to a set position in a direction of approaching each other, so that the airtight door 59 to be tested is placed at a specified position, and then the PLC controller 10 controls the third electric push rod 391 to work, and drives the lifting plate 392 and multiple electric suction cups 40 to move upward together through the third electric push rod 391. At the same time, the PLC controller 10 controls the electric suction cup 40 to work, and uses the electric suction cup 40 to adsorb the airtight door 59 to be tested, and drives the airtight door 59 to be tested to move upward together through the third electric push rod 391 and the electric suction cup 40, so that the airtight door 59 to be tested is in contact with the detection frame 131, and the door gap of the airtight door 59 to be tested is located in the return groove 14. When the airtight door 59 to be tested and the detection frame After the airtight door 59 to be tested and the detection frame 131 are in contact, a reaction force will be generated between the airtight door 59 to be tested and the detection frame 131. The detection frame 131 is fixedly arranged, and the airtight door 59 to be tested will stop moving immediately under the action of the reaction force. The electric suction cup 40 and the airtight door 59 to be tested are connected by the electric suction cup 40, and the lower end of the electric suction cup 40 is connected to the lifting plate 392 through the elastic block 60. Therefore, when the airtight door 59 to be tested stops moving, the lifting plate 392 will still move upward for a short distance under the thrust of the third electric push rod 391, so that the airtight door 59 to be tested and the detection frame 131 are in close contact. When the lifting plate 392 continues to move upward, the lifting plate 392 will drive The induction tube 41 moves upwards to a very short position, and the upper end of the induction frame 42 pushes the airtight door 59 to be tested. Therefore, the induction frame 42 moves downwards relatively in the induction tube 41, so that the lower end of the induction frame 42 is squeezed to the squeezing switch 43 (after the induction frame 42 contacts the airtight door 59 to be tested, it moves downwards to a set position, very close to the squeezing switch 43 below. When the lifting plate 392 squeezes the elastic block 60 to produce a very small deformation, the induction frame 42 is squeezed downwards to the squeezing switch 43). The squeezing switch 43 transmits an electrical signal to the PLC controller 10. After receiving the electrical signal, the PLC controller 10 controls the third electric push rod 391 to stop working.

[0038] At the same time, the PLC controller 10 will control the air pump 5 to start working. When the air pump 5 is working, the control valve 31 will also open, and a part of the gas delivered by the air pump 5 will be delivered to the timing cylinder 301, so that the air pressure in the space on the left side of the piston block 302 increases, and the piston block 302 will move to the right under the action of the air pressure. In the process of moving to the right, the piston block 302 will drive the sliding block 34 to rotate clockwise by a certain angle through the bent rod 33, so that the right side of the sliding block 34 contacts the inside of the timing cylinder 301, and the air pump 5 will extract the gas inside the detection frame 131 through the suction pipe 6, so that the air pressure in the detection groove 16 is reduced, and the piston plate 18 will be under the action of the air pressure. When the air pressure in the detection frame 131 is reduced to the set value, the piston seat 55 will squeeze the press switch 56, and the pressure in the detection frame 131 will be reduced. The switch 56 will transmit an electrical signal to the PLC controller 10. After receiving the electrical signal, the PLC controller 10 will control the air pump 5 to stop working, so that the detection frame 131 is maintained at a set negative pressure state, and the control valve 31 is controlled to close. The gas in the space on the left side of the piston block 302 will be slowly discharged through the microporous plate 32 under the elastic force of the piston block 302 and the spring. In the process of moving to the left, the piston block 302 will drive the sliding block 34 to rotate counterclockwise by a certain angle through the bending rod 33, so that the left side wall of the sliding block 34 contacts the lower inner wall of the timing cylinder 301. The left side wall of the sliding block 34 is connected to the electric contact plate 35. When the sliding block 34 slides to the left During the process, it will contact the electric contact block 36, the electric contact plate 35 will be electrically connected to the external power supply, and the electric contact block 36 will be electrically connected to the PLC controller 10. When the electric contact plate 35 and the electric contact block 36 are in contact, an electric signal will be sent to the PLC controller 10. After the PLC controller 10 receives the electric signal, it means that the airtight door 59 to be tested has been kept in the negative pressure state for a set time. The PLC controller 10 will control the regulating valve 58 to open, so that the air pressure inside the detection frame 131 returns to normal, and at the same time control the third electric push rod 391 to move downward, and the first electric push rod 7 to move upward, so that the airtight door 59 to be tested after the test is placed back on the transmission belt for transportation:

[0039] When there is an area of ​​air leakage in the airtight door, when the internal air pressure of the detection slot 16 is reduced, the external air will pass through the air leakage of the airtight door 59 to be tested and enter the bottom of the piston plate 18, so that the piston plate 18 can continue to move upward, and the piston plate 18 will drive the conductive frame 19 to move upward together. The conductive frame 19 will contact the resistor plate 20 during the upward movement. The conductive frame 19 is electrically connected to the external power supply, and the upper end of the resistor plate 20 is electrically connected to the electromagnetic block 48. When the conductive frame 19 contacts the resistor plate 20, an electrical signal will be transmitted to the electromagnetic block 48. After the electromagnetic block 48 is energized, a magnetic attraction will be generated, and the electromagnetic block 48 will attract the permanent magnet plate 50 and the connecting block 49 to move upward together. The connecting block 49 will drive the metal plate 51 to move upwards. The metal plate 51 will contact the metal block 52 during the upward movement. The metal plate 51 is electrically connected to the external power supply. The metal block 52 is electrically connected to the lamp bead 47. After the metal plate 51 and the metal block 52 are in contact, the external current will be transmitted to the lamp bead 47, so that the lamp bead 47 will emit light. In addition, within the set time, the larger the leak point of the airtight door 59 to be tested, the higher the position where the piston plate 18 drives the conductive frame 19 to move upwards, so that the magnetic attraction generated by the electromagnetic block 48 is greater, and the higher the position where the metal plate 51 moves upwards, the more lamp beads 47 will light up. By observing the number of lamp beads 47 that light up, the size of the leak point can be judged:

[0040] When the piston plate 18 moves upward, the piston plate 18 will squeeze the telescopic airbag 26 upward, so that the gas inside the telescopic airbag 26 is transported to the drainage chamber 22 through the air pressure tube 25, so that the air pressure in the drainage chamber 22 increases, and the pigment in the drainage chamber 22 is discharged through the pressure valve 28 and the marking tube 27 under the action of the air pressure, so that the pigment drips into the leakage area of ​​the air-tight door 59 to be tested, which is convenient for the operator to quickly find the leakage point for repair, thereby improving the convenience of the operator to repair the air-tight door; when the inspection of the air-tight door 59 to be tested is completed, the piston plate 18 will move downward under the elastic force of the spring, and the piston plate 18 will drive the telescopic airbag 26 to expand, thereby extracting the air pressure in the drainage chamber 22 through the air pressure tube 25, and the pigment in the pigment box 211 will be transported to the drainage chamber 22 through the discharge pipe 212 and the one-way valve 23 under the action of negative pressure for storage and standby.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
