Description

Technical Field

[0001] This invention relates to the field of mask testing technology, and in particular to a testing device for the manufacture of medical masks. Background Technology

[0002] As essential personal protective equipment, medical masks' filtration performance directly impacts the health and safety of healthcare workers and users, serving as a crucial barrier against the spread of pathogens and aerosols. In the large-scale manufacturing of medical masks, filtration performance testing is a core element in ensuring product quality and compliance with industry and national standards. The mask's filtration stability under different environmental conditions, the degree of automation in the testing process, and the testing accuracy directly determine testing efficiency and the product's pass rate.

[0003] Currently, existing testing equipment for medical mask manufacturing primarily focuses on testing the conventional filtration efficiency of masks. Its core structure typically includes an aerosol generator, sampler, sample clamp, aerosol chamber, and control unit. By fixing the mask to the clamp, it simulates the aerosol filtration process under normal conditions, thereby testing the mask's filtration efficiency and airflow resistance to meet basic quality testing requirements. Simultaneously, some testing devices incorporate artificial head molds to simulate breathing resistance and leakage under human wearing conditions, further enhancing the realism of the testing. Furthermore, some technologies are exploring the use of climate simulation chambers to control the temperature and humidity of the testing environment to adapt to the testing needs of different usage scenarios.

[0004] Existing testing devices often employ a single-chamber design for environmental simulation, which can only simulate one or a few fixed environmental conditions. They cannot simultaneously simulate and quickly switch between multiple special environments such as high temperature and low temperature. Furthermore, the connection between the testing chamber and the environmental simulation chamber is mostly fixed, lacking a flexible switching mechanism. If it is necessary to test the filtration performance of masks under different environments, the masks must be manually transferred or the testing components adjusted, which is cumbersome. This not only significantly reduces testing efficiency but also easily leads to mask installation deviations and damage to the testing environment due to manual intervention, affecting the accuracy and consistency of the test results. Summary of the Invention

[0037] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0038] 1. In this invention, the T-shaped frame can be connected to the detection chamber via a connector, and the inner ring plate can be rotated by rotating the base to switch the detection chamber to different environmental simulation chambers for special environmental simulation testing; and after placing multiple detection chambers in different environmental simulation chambers, synchronous simulation of different special environments can be achieved, thereby realizing the filtration efficiency and airflow resistance of medical masks under different special environments.

[0039] 2. In this invention, after the connector is separated from the testing chamber, the T-shaped frame rotates through the rotating base to align the mask disassembly and assembly mechanism with the testing chamber of the mask to be disassembled and assembled. By controlling the connector, the testing chamber can be driven to rotate in the placement frame, so that the head mold faces the conveyor belt.

Then, it is first connected to the docking tube and pushed into the mouthpiece tube in the detection chamber to complete the secondary docking. The solution in the water bottle and the servo piston breathing system are used to circulate and rinse the mouthpiece tube. The rinsed solution is then recycled back into the water bottle, which can effectively remove residual contaminants in the piston cylinder and avoid cross-contamination of the sampled samples in the subsequent detection process. The cleaning and sampling are completed simultaneously, simplifying the operation process and further improving the reliability of the detection data.

[0071] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0072] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0073] Example

[0074] according to Figures 1-11 ,like Figures 1-3 As shown in the figure, the medical mask manufacturing and testing device provided in this embodiment of the invention includes an outer ring support 1 and a rotating base 11, and also includes a plurality of environmental simulation chambers 4 that can be detachably installed on the outer ring support 1;

[0075] An inner ring plate 12 is rotatably connected to the inner side of the rotating base 11. Several mounting frames 1201 are fixedly connected to the inner wall of the inner ring plate 12. Each mounting frame 1201 has a detection chamber 41 rotatably connected inside it. Figure 8 In the process, the detection chamber 41 is equipped with a head mold 4101, a mouthpiece tube 4102 and a servo piston breathing system 42. The detection chamber 41 is equipped with a docking tube 4103. The servo piston breathing system 42 is connected to the mouthpiece tube 4102. After the detection chamber 41 rotates in the placement frame 1201, it communicates with the environmental simulation chamber 4. The servo piston breathing system 42 simulates breathing through the docking tube 4103 to detect the detection mask 2401 on the head mold 4101.

[0076] A T-shaped frame 2 is fixed to a rotating base 11. An external driving device is installed on the rotating base 11 to drive the T-shaped frame 2 to rotate. Slide plates 3 are slidably provided on both sides of the T-shaped frame 2 through a lifting structure 31. The lifting structure 31 is installed on the T-shaped frame 2, and the sliding plate 3 is controlled to move up and down on the T-shaped frame 2 by the extension action of the lifting structure 31.

[0077] The connector 13 on the fixed T-frame 2, such as Figure 1 and Figure 2 In this process, the connector 13 can be movably connected to the detection chamber 41 and drive the detection chamber 41 to rotate. After the T-shaped frame 2 completes the connection with the detection chamber 41 through the connector 13, the inner ring plate 12 can be synchronously rotated in the outer ring bracket 1 while the T-shaped frame 2 rotates. This is used to drive the detection chamber 41 in the placement frame 1201 to switch between different environmental simulation chambers 4. The orientation of the head mold 4101 can be changed by driving the detection chamber 41 to rotate in the placement frame 1201 through the connector 13. When the head mold 4101 faces the inner side of the inner ring plate 12, the head mold 4101 is exposed outside the placement frame 1201, which can be used for mask removal and cleaning sampling. At the same time, the detection chamber 41 also seals the space between the placement frame 1201 and the environmental simulation chamber 4 to prevent the simulated environment in the environmental simulation chamber 4 from polluting the external detection environment.

[0078] A conveyor belt 21 is installed on the T-shaped frame 2. The conveyor belt 21 is equipped with a detection mask 2401 and a water bottle 23. The conveyor belt 21 can transport the detection mask 2401 and the water bottle 23. The detection mask 2401 and the water bottle 23 can be loaded on the horizontal section of the T-shaped frame 2 and then transported to the bottom end of the T-shaped frame 2 via the conveyor belt 21.

[0079] The mask assembly / disassembly mechanism 5 and the sampling mechanism 6 are fixedly attached to the skateboard 3;

[0080] The mask disassembly / assembly mechanism 5 includes:

[0081] The removable and telescopic structure 51 is fixed to the slide plate 3;

[0082] The movable gripper 52 is fixedly connected to the movable end of the disassembly and reassembly telescopic structure 51;

[0083] like Figure 4 In the middle, movable pull ears 53 are set on both sides of the head mold 4101. The disassembly and assembly telescopic structure 51, movable gripper 52 and movable pull ears 53 can be used to pick up and put on the test mask 2401 on the conveyor belt 21, and disassemble and assemble on the movable pull ears 53. The disassembly and assembly telescopic structure 51 can send and receive the movable gripper 52 to deliver the test mask 2401 between the movable pull ears 53 and the conveyor belt 21, while the movable gripper 52 is used to clamp or release the test mask 2401.

[0084] The sampling mechanism 6 includes:

[0085] Sampling telescopic structure 61 fixed to the slide plate 3;

[0086] Movable clamping component 62 is fixedly connected to the movable end of the sampling telescopic structure 61;

[0087] A docking tube 63 is fixed to the slide plate 3 and is located in the moving path of the telescopic structure 61;

[0088] The sampling telescopic structure 61 and the movable clamp 62 can be used to pick up and put down the water bottle 23 on the conveyor belt 21, and control the insertion action between the water bottle 23, the docking tube 63 and the mouthpiece tube 4102.

[0089] like Figure 1 and Figure 2 In this context, the connector 13 includes:

[0090] A stabilizing subframe 1301 is fixed to the T-shaped frame 2. A column 1305 is fixed to the other end of the stabilizing subframe 1301. The bottom end of the column 1305 is circumferentially slidably connected to the top of the outer ring bracket 1.

[0091] A follower frame 1302 is fixed to the slide plate 3, and the other end of the follower frame 1302 is slidably sleeved on the column 1305;

[0092] Rotate the multi-faceted insert 1303 connected to the follower frame 1302, such as Figure 6 and Figure 8 In the process, a docking sleeve 4103 is fixedly inserted into the center of the detection chamber 41. The bottom end of the multi-faceted rod 1303 is movably inserted into the docking sleeve 4103, and the top end of the multi-faceted rod 1303 is fixedly connected to a head mold motor 1304. The head mold motor 1304 is fixedly mounted on the follower frame 1302. The stabilizing sub-frame 1301 and the column 1305 are used to stabilize the rotation of the T-shaped frame 2. At the same time, the follower frame 1302 moves up and down with the slide plate 3, thereby driving the multi-faceted rod 1303 to complete the insertion and separation action with the docking sleeve 4103. In addition, the other end of the follower frame 1302 is slidably sleeved on the column 1305, which can share the load of the head mold motor 1304. After the multi-faceted rod 1303 is inserted into the docking sleeve 4103, it can... The head mold motor 1304 drives the detection chamber 41 to rotate inside the mounting frame 1201, which controls the orientation of the head mold 4101. When the head mold 4101 faces the inner side of the inner ring plate 12, it is located outside the opening of the mounting frame 1201. When the head mold 4101 faces the outer side of the inner ring plate 12, it can be connected to the environmental simulation chamber 4. After the multi-faceted plug 1303 is inserted into the docking plug 4103, the rotating base 11 drives the T-shaped frame 2 to rotate. The detection chamber 41 and the mounting frame 2101 can drive the inner ring plate 12 to rotate inside the outer ring support 1. This allows the detection chamber 41 to selectively connect with the required environmental simulation chamber 4, improving the flexibility of the detection chamber 41 in matching the required environmental simulation chamber 4 when switching between different simulation scenarios.

[0093] like Figure 3 In the process, multiple carrying plates 22 are fixed to the outer wall of the conveyor belt 21. Mask racks 2201 and water bottle racks 2202 are respectively mounted on the carrying plates 22, spaced apart. The mask assembly / disassembly mechanism 5 and the sampling mechanism 6 are located on opposite sides of the T-shaped frame 2. The arrangement of the mask assembly / disassembly mechanism 5 and the sampling mechanism 6 on opposite sides of the T-shaped frame 2 ensures that the operation of assembling / disassembling masks via the mask assembly / disassembly mechanism 5 and the operation of cleaning / sampling via the sampling mechanism 6 do not obstruct each other, and also allows for smooth sliding... The force on both sides of plate 3 is more even. During the continuous operation of disassembling masks and cleaning and sampling, since the mask rack 2201 and water bottle rack 2202 are set at intervals, the mask rack 2201 and water bottle rack 2202 at the bottom of the vertical section of T-frame 2 can be located on the corresponding sides respectively. When rotating T-frame 2 to adjust the position of mask disassembly mechanism 5 and sampling mechanism 6, the positions of mask rack 2201 and water bottle rack 2202 can be switched synchronously, so that the conveyor belt 21 does not need to be started again to adjust the position of mask rack 2201 and water bottle rack 2202 separately.

[0094] like Figure 6 and Figure 7 In this arrangement, a retaining plate 2203 is rotatably connected to the water bottle rack 2202 via a torsion spring. An annular groove adapted to the retaining plate 2203 is provided on the outer wall of the water bottle 23. One end of the retaining plate 2203 is engaged with the water bottle 23 to secure it within the water bottle rack 2202. The side of the retaining plate 2203 away from the carrying plate 22 is designed with a slanted opening 2206. When the water bottle 23 detaches from the carrying plate 22, it will not detach automatically due to the interaction between the retaining plate 2203 and the annular groove; it requires additional clamping. The clamping trigger control of the holding member 62, when loading water bottle 23 into water bottle rack 2202, the bottom outer ring of water bottle 23 abuts against the inclined opening 2206, which can cause one end of the clamping plate 2203 to tilt up on water bottle rack 2202, so that water bottle 23 can be smoothly inserted into water bottle rack 2202. During the insertion process, one end of the clamping plate 2203 opens. After the clamping plate 2203 is inserted into the corresponding annular groove on water bottle 23, the clamping of the movable clamping member 62 on water bottle 23 is released, thus completing the loading action of water bottle 23.

[0095] like Figure 3 and Figure 7 In the process, extension blocks 2204 are fixedly connected to both sides of the carrying plate 22, and U-shaped calibration slides 2205 are fixedly connected to both sides of the T-shaped frame 2. During the movement of the carrying plate 22, when the extension blocks 2204 move to the same height as the detection chamber 41, the extension blocks 2204 slide into the groove of the U-shaped calibration slide 2205. The position and posture of the mask rack 2201 and the water bottle rack 2202 are adjusted by the U-shaped calibration slide 2205, so that the movable gripper 52 can hold the detection mask 2401 on the mask rack 2201 and the movable clamping member 62 can hold and control the water bottle 23 on the water bottle rack 2202.

[0096] like Figure 10 and Figure 11 In this device, one end of the movable pull ear 53 is fixedly connected to a side clamp guide rod 5302, which is slidably connected to the side wall of the detection chamber 41. A tensioning cylinder 5301 is installed on the inner wall of the detection chamber 41, and the output end of the tensioning cylinder 5301 is fixedly connected to the side clamp guide rod 5302. Both sides of the detection mask 2401 are detachably connected to mask side clamps 24. The mask side clamps 24 are provided so that when the detection mask 2401 is inserted into the movable pull ear 53, and the tensioning cylinder 5301 is activated to drive the movable pull ear 53 to retract into the detection chamber 41, the detection mask 2401 deforms and slides in the movable pull ear 53 by pressing against the arc surface of the head mold 4101. The movable pull ear 53 and the mask side clamps 24 abut against each other, thereby pulling the detection mask 2401 to deform and adhere tightly to the surface of the head mold 4101.

[0097] like Figure 4 - Figure 6 In this context, the movable clamping member 62 includes:

[0098] A bottle-clamping cylinder 6201 is fixedly installed on the telescopic end of the sampling telescopic structure 61;

[0099] A probe plate 6202 is slidably connected to the output end of the sampling telescopic structure 61, and the probe plate 6202 is fixedly connected to the output end of the bottle clamping cylinder 6201.

[0100] The clamping plate 6203 and the top rod 6204 are fixed to the probe plate 6202. The clamping plate 6203 is longer than the top rod 6204, so that the clamping plate 6203 pre-clamps the water bottle 23 and then the top rod 6204 pushes against one end of the clamping plate 2203, so that the other end of the clamping plate 2203 is separated from the water bottle 23. When it is necessary to place the water bottle 23 in the water bottle rack 2202, the top rod 6204 separates from the clamping plate 2203 first, and then the clamping plate 6203 releases the water bottle 23, making it more stable and reliable to take the water bottle 23 off and put it on the water bottle rack 2202.

[0101] A V-shaped rod 6301 is fixedly connected to the outer wall of the docking tube 63. A guide rod 6302 is fixedly connected to one side of the V-shaped rod 6301. A fixing frame 6304 is slidably sleeved on the outer wall of the guide rod 6302. The fixing frame 6304 is fixedly connected to the slide plate 3. A return spring 6303 is slidably sleeved on the rod wall of the guide rod 6302. One end of the return spring 6303 is fixedly connected to the end of the guide rod 6302 away from the V-shaped rod 6301, and the other end of the return spring 6303 is fixedly connected to the fixing frame 6304. After the movable clamping member 62 clamps the water bottle 23, the sampling telescopic structure 61 is activated to transfer the water... When bottle 23 is delivered into mouthpiece tube 4102, docking tube 63 is pre-inserted into bottle 23 along this movement trajectory. During the insertion process of bottle 23 and docking tube 63, docking tube 63 drives guide rod 6302 to slide on fixed frame 6304 through V-shaped rod 6301, causing return spring 6303 to deform. The movement of docking tube 63 forms resistance, which facilitates quick insertion of docking tube 63 and bottle 23, thereby preventing incomplete insertion and leakage of solution in bottle 23. When pulled out from mouthpiece tube 4102, the force generated by the deformation of return spring 6303 can drive docking tube 63 to actively separate from mouthpiece tube 4102.

[0102] like Figure 8In this process, a bidirectional pump 64 is installed on the outer wall of the docking tube 63. A sealing isolation ring 65 and a limiting ring are also fixedly sleeved on the outer wall of the docking tube 63. Short pipes for pumping and draining water are installed on the pipe walls on both sides of the sealing isolation ring 65 of the docking tube 63. One-way valves are installed on each of the short pipes. A gas cylinder 2301 is installed on the outer wall of the water bottle 23. After the limiting ring on the docking tube 63 blocks the port of the mouthpiece tube 4102, the sealing isolation ring 65 is located inside the mouthpiece tube 4102, dividing the interior of the mouthpiece tube 4102 into two spaces. The one-way valves restrict the one-way water inflow and one-way water outflow of the two short pipes. When a negative pressure is generated inside the servo piston breathing system 42, the bidirectional pump 64 is activated to supply water to one side of the mouthpiece tube 4102 through a short tube, causing the servo piston breathing system 42 to pump water. When the servo piston breathing system 42 drains water from the mouthpiece tube 4102, the bidirectional pump 64 is controlled to pump water to draw water from inside the mouthpiece tube 4102 through the short tube on the other side and pump the water back into the water bottle 23. Repeated operation can circulate and rinse the mouthpiece tube 4102. It should be noted that when the bidirectional pump 64 pumps the solution inside the water bottle 23, the gas cylinder 2301 can be deformed to relieve and balance the internal gas pressure of the water bottle 23, avoiding severe deformation of the water bottle 23.

[0103] like Figure 8 and Figure 9 In the process, the servo piston breathing system 42 includes:

[0104] A piston cylinder 4202 is fixedly installed on the inner wall of the detection chamber 41. A piston is slidably connected inside the piston cylinder 4202. A servo motor 4201 is fixedly connected to the top of the piston cylinder 4202. A threaded rod is fixedly connected to the output end of the servo motor 4201. The bottom end of the threaded rod passes through the side wall of the piston cylinder 4202 and extends to the bottom end of the inner wall of the piston cylinder 4202. The piston is threaded onto the threaded rod. The bottom end of the piston cylinder 4202 is fixedly connected to an air extraction pipe 4203 and an air outlet pipe 4204. Both the air extraction pipe 4203 and the air outlet pipe 4204 are equipped with one-way valves. Humidification and heating devices are also installed on the pipes of the air extraction pipe 4203 and the air outlet pipe 4204 to establish a simulated breathing system. The humidity and temperature are simulated to simulate the actual use environment of the mask. The ends of the suction pipe 4203 and the exhaust pipe 4204 away from the piston cylinder 4202 are respectively fixedly connected to the outer walls of both ends of the mouthpiece tube 4102. The threaded rod and piston are controlled by the servo motor 4201 to rise and fall inside the piston cylinder 4202 to establish the air pressure environment inside the piston cylinder 4202. When simulating breathing, not only can air be drawn into the piston cylinder 4202 through the suction pipe 4203 and the exhaust pipe 4204, but also after the docking tube 63 is inserted into the mouthpiece tube 4102, the solution can be drawn out. After being used in conjunction with the water bottle 23, the docking tube 63, the bidirectional pump 64, and the sealing isolation ring 65, the mouthpiece tube 4102 and the inside of the servo piston breathing system 42 are circulated and cleaned.

[0105] In this embodiment, the mask 2401 and water bottle 23 are pre-assembled on the mask rack 2201 and water bottle rack 2202 on the conveyor belt 21 on the horizontal section of the T-frame 2. The mask 2401 needs to have mask side clips 24 pre-installed on both sides. When it is necessary to install a medical mask in any testing chamber 41, the T-frame 2 is rotated by rotating the base 11, so that the mask installation and removal mechanism 5 faces the testing chamber 41 to be installed. The sliding plate 3 is controlled to move down by the lifting structure 31. The follower frame 1302 drives the multi-faceted insertion rod 1303 to insert into the docking cylinder 4103. The head mold motor 1304 is activated, causing the detection chamber 41 to rotate within the placement frame 1201, turning the head mold 4101 towards the movable gripper 52. The movable gripper 52 is moved above the mask frame 2201 by controlling the disassembly and reassembly telescopic structure 51. After the conveyor belt 21 moves the mask frame 2201 upwards, the movable gripper 52 picks up the medical mask. The disassembly and reassembly telescopic structure 51 is controlled by the lifting structure 31. The mask is removed by moving the movable gripper 52 upwards, and the mask is delivered above the movable pull ears 53 by extending the telescopic structure 51. Then, the movable gripper 52 is moved downwards by the slide plate 3, placing the two sides of the mask in the two movable pull ears 53. The mask side clips 24 are located outside the two movable pull ears 53. The tension cylinder 5301 is activated to contract, and the test mask 2401 deforms as it presses against the face of the head mold 4101. The test mask 2401 slides within the movable pull ears 53 until the mask side clips are engaged. 24. Gradually press against the movable pull ear 53 to make the test mask 2401 fit tightly against the face of the head mold 4101, thereby completing the installation of the mask on the head mold 4101. Then, the head mold motor 1304 controls the multi-faceted insertion rod 1303 to rotate, driving the test chamber 41 to rotate. After turning the head mold 4101 on the test chamber 41 to face the environment simulation chamber 4, the simulated environment test can be carried out. The mask removal process can be carried out by reversing the installation operation. The mask removal, installation and transfer on the head mold 4101 can be completed automatically.

[0106] After disassembly, when sampling the internal nozzle tube 4102 of the head mold 4101, the multi-faceted insert rod 1303 is pulled out of the docking insert 4103 by the sliding plate 3. The T-frame 2 is rotated to adjust the orientation of the water bottle 23 and the sampling mechanism 6 to correspond with the orientation of the detection chamber 41. The height of the sampling telescopic structure 61 and the movable clamping part 62 is adjusted to correspond with the head mold 4101 by the downward movement of the sliding plate 3. The bottle clamping cylinder 6201 is activated to move the probe plate 6202 closer to the water bottle holder 2202. The end of the clamping plate 6203 is first inserted into the corresponding groove on the body of the water bottle 23. As the probe plate 6202 continues to move closer, the water bottle 23... The push rod 6204 presses against the clamping plate 2203, causing the section of the clamping plate 2203 that is engaged with the water bottle 23 to tilt upwards. This tilts upwards through the telescopic end of the sampling telescopic structure 61, causing the movable clamping member 62 to hold the water bottle 23 closer to the docking tube 63. The bottle neck of the water bottle 23 is first inserted into one end of the docking tube 63. Then, the sampling telescopic structure 61 continues to extend, inserting the other end of the docking tube 63 into the mouthpiece tube 4102. After the limiting ring seals the end of the mouthpiece tube 4102, the bidirectional pump 64 is activated, pumping the solution inside the water bottle 23 into the mouthpiece tube 4102 through the short tube. Simultaneously, the servo motor is activated. The piston breathing system 42 uses a servo motor 4201 to drive a piston to move within a piston cylinder 4202, generating negative pressure. This negative pressure draws the solution into the piston cylinder 4202 through the suction pipe 4203. After the solution in the water bottle 23 is completely extracted, air is continuously drawn from the water bottle 23, ensuring that the solution in the suction pipe 4203 is also completely extracted. Then, the bidirectional pump 64 and the servo motor 4201 are controlled to run in reverse. The outlet pipe 4204 discharges the solution into the mouthpiece tube 4102, while the bidirectional pump 64 pumps the solution into the water bottle 23 through another short tube at the end of the connecting tube 63, causing the piston cylinder 4202 and the outlet pipe 4203 to... The solution in 204 is returned to the water bottle 23, and the mouthpiece tube 4102 and piston cylinder 4202 are continuously and repeatedly cleaned. The cleaned solution is collected back into the water bottle 23. The contraction of the sampling telescopic structure 61 controls the movable clamping part 62 to clamp the water bottle 23 and insert it back into the water bottle rack 2202. After the docking tube 63 and water bottle 23 are reset, they are transported to the outside via the conveyor belt 21 and can be used as samples for testing. Not only is the mouthpiece tube 4102 cleaned to avoid cross-contamination caused by multiple uses, but the sample collection is also completed automatically, simplifying the operation process. After the cleaning is completed;

[0107] When it is necessary to switch the testing chamber 41 to different environment simulation chambers 4 for different environment simulation tests, the lifting structure 31 drives the slide plate 3 to move down, so that the multi-faceted insert 1303 is inserted into the docking insert 4103. Then, the rotating base 11 drives the T-shaped frame 2 to rotate, which in turn drives the inner ring plate 12 to rotate inside the outer ring bracket 1, thus switching the testing chamber 4 to the environment simulation chamber 4 that is required for the special environment simulation test. The switching is completed. When the T-shaped frame 2 is rotated separately to adjust the mask disassembly and assembly mechanism 5 and the sampling mechanism 6 to correspond to the positions of different environment simulation chambers 4 to complete the automatic mask disassembly and assembly operation and cleaning and sampling operation, the lifting structure 31 raises the slide plate 3, so that the follower frame 1302 drives the multi-faceted insert 1303 to separate from the docking insert 4103. Then, the rotating base 11 can be used to control the rotation of the T-shaped frame 2 for adjustment.
