[0081] Example 1

[0082] In a specific embodiment 1, Figure 1As shown, an automated adsorption system includes an adsorption test module 1, a pretreatment module 2, and an automatic loading and unloading module: the automatic loading and unloading module includes a free-moving component and a sample tube grabbing component 6 for moving the sample tube 9 to the adsorption test module 1 or the pretreatment module 2; the free-moving component includes an X-axis moving component 3, a Y-axis moving component 4, and a Z-axis moving component 5; the free-moving component controls the movement range of the sample tube grabbing component 6 to include the adsorption test module 1 and the pretreatment module 2; the sample tube grabbing component 6 is arranged on the Z-axis moving component 5; the adsorption test module 1 and the pretreatment module 2 are both provided with an automatic sealing device for cooperating with the sample tube grabbing component 6 to achieve automatic sealing of the sample tube.

[0083] The sample tube grabbing assembly 6 includes a robotic arm and a gripper; the X-axis moving assembly 3 includes an X-axis track; the Y-axis moving assembly 4 includes a Y-axis track; and the Z-axis moving assembly 5 includes a Z-axis track; the X-axis track is connected to the Y-axis track, the Y-axis track is connected to the Z-axis track, the robotic arm is connected to the Z axis, and the gripper is fixed to the end of the robotic arm away from the Z-axis track.

The process of automatic sealing of the sample tube 9 has been fully disclosed in the authorized patent with patent application number 202222684016.1, so this embodiment will not go into details. Those skilled in the art can undoubtedly determine the structure and implementation of the automatic sealing device based on the records of the above patent text.

[0090] After the adsorption test or degassing is completed, the free-moving component in the automatic loading and unloading module drives the sample tube grabbing component 6 to the vicinity of the sample tube 9, and then the robotic arm adjusts the position of the gripper, and the gripper grabs the sample tube 9 and separates it from the adsorption module or pretreatment module 2.

[0093] Example 2

[0094] In a specific embodiment 1, Figure 2 As shown, an automated adsorption system includes an adsorption test module 1, a pretreatment module 2, an automatic loading and unloading module, a sample tube preparation device 7 and a weighing device: the automatic loading and unloading module includes a free moving component and a sample tube grabbing component 6 for moving the sample tube 9 to the adsorption test module 1 or the pretreatment module 2; the free moving component includes an X-axis moving component 3, a Y-axis moving component 4, and a Z-axis moving component 5; the free moving component controls the movement range of the sample tube grabbing component 6, including the adsorption test module 1, the pretreatment module 2, the sample tube preparation device 7 and the weighing device; the sample tube grabbing component 6 is arranged on the Z-axis moving component 5; the adsorption test module 1 and the pretreatment module 2 are both provided with automatic sealing devices for cooperating with the sample tube grabbing component 6 to realize automatic sealing of the sample tube 9.

[0096] like Figure 3 and Figure 4As shown, the elastic sealing device 7-3 includes a sealing base 7-3-1, an annular protrusion 7-3-2, a sealing ring 7-3-3, an auxiliary structure 7-3-4, a fixed structure 7-3-5, a constant force body 7-3-6 and a sealing cover 7-3-7; the sealing cover 7-3-7 and the sealing base 7-3-1 are both provided with internal threads; the upper part of the auxiliary structure 7-3-4 is provided with an insertion part; the lower part of the insertion part and the auxiliary structure 7-3-4 are both provided with external threads; the auxiliary structure 7-3-4 is through-through; the fixed structure 7-3-5 is provided with a cavity for inserting the sample tube 9 and the annular protrusion 7-3-2; the fixed structure 7-3-5 A through-hole is provided for the insertion portion to pass through; a groove for mounting the constant force body 7-3-6 is provided on the upper surface of the fixed structure 7-3-5; the annular protrusion 7-3-2 is fixed relative to the sealing base 7-3-1; the insertion portion passes through the through-hole and is threadedly connected to the sealing cover 7-3-7; the sealing base 7-3-1 is threadedly connected to the auxiliary structure 7-3-4; one end of the constant force body 7-3-6 is fixed relative to the lower surface of the sealing cover 7-3-7, and the other end is fixed relative to the bottom of the groove; the sealing ring 7-3-3 is provided between the upper surface of the annular protrusion 7-3-2 and the cavity; the cavity is provided with an inwardly contracted chamfer 7-3-5-1. The constant force body 7-3-6 is a spring.

[0097] The sample tube grabbing assembly 6 includes a robotic arm and a gripper; the X-axis moving assembly 3 includes an X-axis track; the Y-axis moving assembly 4 includes a Y-axis track; and the Z-axis moving assembly 5 includes a Z-axis track; the X-axis track is connected to the Y-axis track, the Y-axis track is connected to the Z-axis track, the robotic arm is connected to the Z axis, and the gripper is fixed to the end of the robotic arm away from the Z-axis track.

[0098] In this embodiment, the Y-axis moving component 4 can slide along the X-axis track and drive the Z-axis moving component 5 at the same time. The robotic arm can slide along the Z-axis track, thereby driving the gripper to move. Through this design, the gripper can move freely.

[0099] The automatic sealing device in the present utility model refers to the automatic sealing device of the authorized patent with patent application number 202222684016.1.

[0100] In this embodiment, the control of the adsorption test module 1, the pre-processing module 2, and the automatic loading and unloading module all adopts the control center of the existing adsorption system.

[0101] In this embodiment, the pre-processing module 2 is a degassing station.

[0102] In this embodiment, the initial state of the elastic sealing device 7-3 is as follows:

[0103] The constant force body 7-3-6 (spring) is in a compressed state, with one end in contact with the upper surface of the fixed structure and the other end applying an upward elastic force to the sealing cover 7-3-7. The sealing cover 7-3-7 is relatively fixed to the auxiliary structure 7-3-4, so the elastic force is transmitted through the auxiliary structure 7-3-4 to the sealing base 7-3-1, giving it an upward force. The internal annular protrusion 7-3-2 squeezes the sealing ring 7-3-3 against the chamfer 7-3-5-1 in the cavity, preventing it from moving further. Therefore, the elastic sealing device 7-3 always maintains this state under the action of the constant force body 7-3-6.

[0104] The sealing process of this embodiment is as follows:

[0105] Manually pull the sealing base 7-3-1, which simultaneously drives the annular protrusion 7-3-2 and the auxiliary device to slide down along the through hole, driving the sealing cover 7-3-7 downward, further squeezing the constant force body 7-3-6 (spring). As the annular protrusion 7-3-2 moves downward, the force applied to the sealing ring 7-3-3 is reduced, and the sealing ring 7-3-3 returns to its original state.

[0106] Then, manually insert the sample tube 9 from the hole below the sealing base 7-3-1. The tube body of the sample tube 9 passes through the annular protrusion 7-3-2 and the sealing ring 7-3-3 and enters the cavity. The insertion depth of the tube mouth is greater than the depth of the chamfer 7-3-5-1 in the cavity.

[0107] Release the hand holding the sealing base 7-3-1, and the further compressed constant force body 7-3-6 returns to its original shape, squeezing the sealing cover 7-3-7 upward, and at the same time driving the auxiliary device, the sealing base 7-3-1 and the annular protrusion 7-3-2 upward. The annular protrusion 7-3-2 squeezes the sealing ring 7-3-3. When the sealing ring 7-3-3 reaches the chamfer 7-3-5-1, it cannot go any deeper, so it will be compressed and deformed. The sealing ring 7-3-3 closes the gap at the chamfer 7-3-5-1 while applying an inward contraction force to the sample tube 9, thereby fixing and sealing the sample tube 9.

[0108] The automatic crawling process of this embodiment is as follows:

[0109] The control center controls the rotating motor 7-2 to rotate the turntable 7-1, thereby rotating the sample tube 9 to be tested to the grabbing station of the sample tube grabbing assembly 6. Subsequently, the clamping claw clamps the sample tube 9 and drives the sample tube 9 downward. There is friction between the sample tube 9 and the sealing ring 7-3-3. The sample tube 9 drives the sealing ring 7-3-3 downward, pressing the annular protrusion 7-3-2, the sealing base 7-3-1, the auxiliary device, and the sealing cover 7-3-7 downward. The sealing cover 7-3-7 presses down the constant force body 7-3-6. Since the position of the chamfer 7-3-5-1 is always fixed, when the annular protrusion 7-3-2 is downward, the sealing ring 7-3-3 is released and returns to its original state, thereby no longer squeezing and sealing the sample tube 9. After the sample tube 9 is released, the clamping claw grabs the sample tube 9 and leaves. The constant force body 7-3-6 returns to its original shape, presses the sealing cover 7-3-7 upward, drives the auxiliary device, the sealing base 7-3-1 and the annular protrusion 7-3-2 upward, and the elastic sealing device 7-3 returns to its original shape, and the grabbing process ends.

[0110] Generally speaking, the grabbing station should be the elastic sealing device 7-3 corresponding to the outermost side of the turntable 7-1, but the present invention does not limit other positions.

[0111] The operation process of this embodiment is as follows:

[0112] First, the free-moving component in the automatic loading and unloading module drives the sample tube grabbing component 6 to move to the grabbing station of the sample tube 9, and the robotic arm drives the gripper to grab the sample tube 9, and then moves it to the adsorption module or pre-treatment module 2. Subsequently, the robotic arm drives the sample tube 9 to connect with the automatic sealing device on the adsorption module or pre-treatment module 2. The process of automatic sealing of the sample tube 9 has been fully disclosed in the authorized patent with patent application number 202222684016.1, so this embodiment will not go into details. Those skilled in the art can undoubtedly determine the structure and implementation of the automatic sealing device based on the records of the above patent text.

[0113] After the adsorption test or degassing is completed, the free-moving component in the automatic loading and unloading module drives the sample tube grabbing component 6 to the vicinity of the sample tube 9, and then the robotic arm adjusts the position of the gripper, and the gripper grabs the sample tube 9 and separates it from the adsorption module or pretreatment module 2.

[0114] Proceed to the next step or end the process.

[0115] This embodiment adds an automatic loading and unloading module to the existing adsorption system and utilizes the technology of the authorized patent with patent application number 202222684016.1 to add an automatic sealing device with the function of automatically sealing the sample tube 9 to the existing adsorption devices such as the adsorption system and degassing station and the pretreatment module 2. The automatic loading and unloading module combined with the automatic sealing device enables all-day testing of the adsorption system equipment without human supervision; the sample tube 9 can be automatically installed and unloaded between the adsorption test module 1, pretreatment module 2, sample tube 9 pretreatment module, weighing device, etc., thereby greatly saving manpower and improving efficiency.

[0116] Compared with Example 1, this embodiment expands the operating scope of the automatic loading and unloading module to include a weighing device and a sample tube preparation device 7. The sample tube preparation device 7 is also added to store and seal multiple sample tubes 9.

[0117] In a preferred embodiment, Figure 5 As shown, the sample tube preparation device 7 further includes a power unit 7-4, which is disposed above the sealing cover 7-3-7 in the elastic sealing device 7-3 corresponding to the grabbing station of the sample tube 9.

[0118] When the gripper of the robotic arm needs to remove the sample tube 9, the power device 7-4 applies a downward force to the sealing cover 7-3-7, thereby pressing the sealing cover 7-3-7, the auxiliary device, the sealing base 7-3-1, and the annular protrusion downward. The sealing ring 7-3-3 is no longer squeezed, thereby releasing the sample tube 9. This embodiment optimizes the process of the robotic arm removing the sample tube 9 and solves the problem of the tube body being broken due to excessive force when the robotic arm is sampling.

[0119] In the present invention, the power device 7-4 can be a cylinder, an electric cylinder, a hydraulic device, etc., which can apply a certain distance to the sealing cover.

[0120] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
