Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of weight detection, in particular to a vacuum environment weight loading and transferring mechanism and method. BACKGROUND

[0002] In the field of metrological detection, weights, as important measuring instruments, their accuracy is crucial to ensure the reliability of various measurement results. With the continuous development of science and technology, the precision requirement of weight detection is also increasing. In some high-precision measurement scenarios, environmental factors have a greater impact on weight measurement results, especially the presence of air may introduce factors such as buoyancy and airflow interference, thereby affecting the accuracy of weight detection. Accurate weight detection can provide a reliable metrological basis for industrial production, scientific research or other fields, and promote the high-quality development of various industries.

[0003] In the existing weight detection process, in order to reduce the influence of environmental factors on the detection results, it is usually detected in ordinary environment and the error caused by environmental factors is corrected through complex calculation. For example, by measuring the temperature, humidity and air pressure parameters of the environment, the measurement results are corrected using relevant physical formulas. Another common way is to use a relatively closed detection environment, but such a closed environment is often difficult to completely exclude the influence of air, only to reduce the interference of external environment to a certain extent. Some detection mechanisms will choose to detect in a specific constant temperature and humidity laboratory to stabilize the environmental conditions, but still cannot completely eliminate the influence of air on weight detection.

[0004] However, these existing weight detection methods have obvious defects. The method of correcting errors by calculation in ordinary environment is difficult to accurately eliminate the influence of air environmental factors on weight detection due to the complexity and uncertainty of environmental factors, which limits the accuracy of the detection results. Although the relatively closed detection environment and the constant temperature and humidity laboratory improve the detection conditions to a certain extent, they still cannot achieve true air-free interference and cannot meet the requirements of some high-precision weight detection applications. SUMMARY

[0005] To overcome the shortcomings of the prior art, the present application provides a vacuum environment weight loading and transferring mechanism and method, which can effectively avoid the pollution or quality change of the weight caused by air contact before and after detection by automatic detection and transfer of the weight in a full-vacuum or controlled environment, thereby ensuring the high precision of the detection process and the reliability of the results, and realizing the automation and airtightness of the whole process of detection and storage.

[0006] The present application is implemented by the following technical solutions: A vacuum environment weight loading and transferring mechanism, comprising: A vacuum tank, a side wall of which is connected with a conveying channel, the conveying channel is connected with a channel gate, and the conveying channel can communicate with an external detection device; An air system for extracting air or introducing air into an internal space of the vacuum tank; A weight storage mechanism, comprising a supporting seat for carrying a weight to be detected and a vacuum cover covering the supporting seat so that the weight in the vacuum cover is in a vacuum state; A grabbing device arranged in the vacuum tank, the grabbing device is provided with a holding assembly at an end thereof, the grabbing device is used to drive the holding assembly to move, the holding assembly is used to selectively hold the vacuum cover or the weight, after the vacuum cover is moved away from the supporting seat, the holding assembly is used to hold the weight to a detection device connected with the vacuum tank, the holding assembly is used to move the detected weight back to the supporting seat, and finally the vacuum cover is arranged on the supporting seat so that the detected weight is in a vacuum state when the detected weight is taken out from the vacuum tank.

[0007] By adopting the above technical scheme, the vacuum tank provides a large vacuum environment, which is a main space where all operations occur. The conveying channel of the side wall is an interface for the weight to exchange with the external detection device. The air system is responsible for establishing and releasing the vacuum environment in the vacuum tank, and is the basis for realizing the vacuum operation. The weight storage mechanism is a "small vacuum cover", which is specially used to maintain the vacuum state of the weight during non-detection. The grabbing device is located in the vacuum tank and is the "hand" that performs all automated operations. It is responsible for moving the vacuum cover, grabbing the weight, sending the weight to the detection device, taking it back, and finally covering the vacuum cover. The weight is always in a vacuum state during the entire detection, transfer and storage process. In the traditional detection method, the weight is exposed to the atmosphere before and after entering the vacuum detection device, and the air buoyancy and gas adsorption or desorption on the surface of the weight will introduce a mass measurement error. Through the design of the "vacuum cover", the weight is still packaged in its own small vacuum environment when it is taken out from the main vacuum tank. This fundamentally eliminates the influence of the atmospheric environment on the mass stability of the weight, greatly improving the accuracy and repeatability of the detection.

[0008] Optionally, the supporting seat is provided with a first support, an end of the first support away from the supporting seat is connected with a multi-claw supporting piece for supporting the weight, an avoiding groove is formed in a circumferential side of the multi-claw supporting piece, an avoiding space is arranged at a position of the first support opposite to the avoiding groove, the avoiding space communicates with the avoiding groove, and the holding assembly can enter and exit the avoiding space so as to hold or place the weight in the height direction.

[0009] By employing the above technical solution, a multi-claw support is used to stably support the bottom of the weight. Clearance grooves and clearance spaces are specially designed channels on the support and its supporting components. It is clear that the lifting assembly (the end of the gripping device) can enter and exit through these grooves and spaces to "lift" or "place" the weight from directly below. This "lifting" operation solves a key mechanical problem: how to stably pick up the weight without contacting its delicate sides or top surface. By "lifting from below," scratches or contamination that clamping or gripping might cause to the weight's surface are avoided. This structural design ensures that the lifting assembly can precisely enter under the weight for vertical lifting and lowering. This is crucial for alignment and stability during placement and picking, reducing the risk of collisions or drops.

[0010] Optionally, the multi-claw support includes a tray and a support block mounted on the tray, wherein the support block has a stepped structure to accommodate weights of different sizes.

[0011] By adopting the above technical solution, weights of different grades and qualities typically have different diameters. The stepped structure means that a single support component can provide multiple support surfaces of different diameters, thus accommodating various weight specifications without requiring a separate support component for each type of weight. This improves the versatility and efficiency of the equipment and reduces costs.

[0012] Optionally, the lifting assembly includes an open arcuate portion and a lifting portion disposed inside the arcuate portion.

[0013] By adopting the above technical solution, the opening design allows the lifting component to easily approach and surround the support structure of the weight or vacuum chamber from the side without interference. Separating the functions of "approach and positioning" (via the arc-shaped portion) from "bearing and lifting" (via the lifting portion) results in a clear structure that facilitates complex grasping actions.

[0014] Optionally, the lifting part has a multi-level stepped structure with a gap in the middle.

[0015] By adopting the above technical solution, the stepped lifting section can be well matched with the bottom of weights of different sizes, achieving stable lifting. The "open center" design is ingenious, allowing the lifting section to avoid the support rod in the center of the support base when approaching the weight. This allows the lifting component to extend deep under the weight without colliding with the support structure.

[0016] Optionally, a support plate is connected to the top of the vacuum hood, and the top surface of the arc portion can abut against the bottom surface of the support plate.

[0017] By adopting the above technical solution, the same lifting component can both grasp weights (using the inner lifting part) and remove the vacuum cover (using the top surface of the outer arc part). This simplifies the design of the gripping device, eliminating the need for two different grippers and reducing system complexity and cost. A dedicated and stable interface is provided to move the vacuum cover, avoiding direct contact with the cover body and preventing damage or tilting.

[0018] Optionally, the top of the arc portion is provided with a first conical slope, which slopes downwards towards the center of the arc portion, and the bottom of the support plate is provided with a second conical slope that matches the first conical slope.

[0019] By employing the above technical solution, when the lifting assembly moves upwards and approaches the pallet, the two conical ramps interact, automatically guiding the lifting assembly and the vacuum chamber to align at the center. This greatly improves the accuracy and reliability of the docking, and even minor initial positioning deviations in the gripping device can be automatically corrected. This is crucial for accurately placing the vacuum chamber back into the support to form a vacuum seal.

[0020] Optionally, it also includes a first transfer seat and a second transfer seat disposed inside the vacuum tank, wherein the first transfer seat is used to support the weight storage mechanism and the second transfer seat is used to support the vacuum hood.

[0021] By adopting the above technical solution, the first transfer seat supports the entire weight storage mechanism, while the second transfer seat is specifically used to temporarily place the removed vacuum cover. This makes the operation process clearer and more orderly. The gripping device no longer needs to "hold" the vacuum cover while moving the weights. It can first place the vacuum cover on the dedicated second transfer seat, and then "lighten up" to handle the weights. Temporarily storing the vacuum cover in a fixed position is much more stable than having the robotic arm hold it up all the time, reducing the risk of the vacuum cover shaking, colliding, or falling due to the movement of the robotic arm.

[0022] A method for loading and transferring weights in a vacuum environment includes the following steps: S1. Provide a weight storage mechanism, wherein the weight storage mechanism contains weights in a vacuum state; S2. Place the weight storage mechanism inside the vacuum container and evacuate the vacuum container; S3. Provide a gripping device, use the gripping device to open the weight storage mechanism, and transfer the weights in the weight storage mechanism to the detection device which is also in a vacuum state; S4. After the weight is detected, the gripping device is used to move the weight back into the weight storage mechanism, and the gripping device is used to close the weight storage mechanism. S5. Air is introduced into the vacuum tank, disrupting the vacuum environment inside the vacuum tank; S6. Remove the weight storage mechanism from the vacuum container.

[0023] By adopting the above technical solution, it is ensured that the weights do not come into contact with the atmosphere throughout the entire testing cycle, thereby ensuring the highest testing accuracy. This provides a standardized and repeatable operating procedure for high-precision weight testing, ensuring that each test is conducted under the same ideal conditions.

[0024] A method for loading and transferring weights in a vacuum environment, wherein the gripping device uses a lifting method to pick up and place weights and to open and close a weight storage mechanism.

[0025] By adopting the above technical solution, it is emphasized that this method is achieved through a specific operating method that minimizes damage to the weights and maximizes stability, namely, lifting them from below.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses an air system to extract or introduce air into the internal space of the vacuum tank, and uses a gripping device to move the weight to a detection device connected to the outside of the vacuum tank. After detection, the weight is moved back to the weight storage mechanism, which can keep the weight in a vacuum state at all times and avoid the influence of air buoyancy and airflow interference factors on the accuracy of weight detection. 2. This application provides a clearance groove on the periphery of the multi-claw support on the support base, and the first support is provided with clearance space. The lifting component can enter and exit the clearance space to lift or place weights, which facilitates the lifting and placing of weights. 3. The support block of the multi-claw support component in this application has a stepped structure, which can be adapted to weights of different specifications, thus improving the versatility of the equipment.

Detailed Implementation

[0029] The following will be combined with the appendix Figures 1-10 The technical solutions of the various embodiments of this application have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Example 1 Reference Figures 1-2 This application discloses a vacuum environment weight loading and transfer mechanism, including a vacuum tank 1, an air system 2, a weight storage mechanism 3, and a gripping device 4. The vacuum tank 1 has a conveying channel 11 connected to its side wall, and a channel gate 12 connected to the conveying channel 11. The conveying channel 11 can communicate with an external detection device. The air system 2 is used to extract or introduce air into the internal space of the vacuum tank 1. The weight storage mechanism 3 includes a support 31 and a vacuum cover 32. The support 31 is used to support the weight 5 to be tested, and the vacuum cover 32 is placed on the support 31 to ensure that the weight 5 inside the vacuum cover 32 is properly positioned. In a vacuum state; the gripping device 4 is located inside the vacuum tank 1, and the end of the gripping device 4 is provided with a lifting component 41. The gripping device 4 is used to drive the lifting component 41 to move. The lifting component 41 is used to selectively grip the vacuum cover 32 or the weight 5. After the vacuum cover 32 is removed from the support 31, the lifting component 41 can be used to grip the weight 5 to the detection device connected to the outside of the vacuum tank 1. The lifting component 41 is used to move the detected weight 5 back to the support 31. Finally, the vacuum cover 32 is placed on the support 31 so that the weight 5 is in a vacuum state when it is taken out of the vacuum tank 1 after the test.

[0031] Specifically, vacuum tank 1 is a relatively closed container, and its material can be high-strength stainless steel, which has good sealing properties and corrosion resistance. Vacuum cover 32 can be a transparent glass cover, allowing for easy observation of the weights 5 inside. The conveying channel 11 is connected to the side wall of vacuum tank 1, providing a passage for the weights 5 to enter and exit vacuum tank 1. The conveying channel 11 can be a circular pipe, and its connection to vacuum tank 1 must be well-sealed to prevent air leakage. The channel gate 12 is used to control the opening and closing of the conveying channel 11. It can be an electric gate, driven by a motor to open and close, facilitating communication or isolation with external detection devices.

[0032] The air system 2 mainly consists of a vacuum pump and air valves. The vacuum pump is used to extract air from the vacuum tank 1 to achieve a vacuum state. A rotary vane vacuum pump can be used, which features fast pumping speed and high vacuum. The air valves are used to control the introduction or discharge of air. Solenoid valves can be used for easy automation. When air needs to be extracted, the vacuum pump and the corresponding valve are opened to extract air from the vacuum tank 1; when air needs to be introduced, the vacuum pump is turned off and the air inlet valve is opened to allow air to enter the vacuum tank 1. The support 31 of the weight storage mechanism 3 can be a flat plate structure, and the material can be aluminum alloy, which has the advantages of light weight and high strength. The gripping device 4 can be a robotic arm with multiple movable joints, which can flexibly drive the movement of the lifting component 41.

[0033] Reference Figure 2 and Figure 3 It also includes a first transfer seat 13 and a second transfer seat 14 disposed inside the vacuum tank 1. The first transfer seat 13 is used to support the weight storage mechanism 3, and the second transfer seat 14 is used to support the vacuum cover 32. The first transfer seat 13 and the second transfer seat 14 can be simple cylindrical structures, and the material can be plastic, which has a certain buffering performance to protect the weight 5 and the vacuum cover 32.

[0034] Reference Figure 4 and Figure 5 The support base 31 is provided with a first support member 311. The end of the first support member 311 away from the support base 31 is connected to a multi-claw support member 312 for supporting the weight 5. The multi-claw support member 312 has a relief groove 3121 on its periphery. The first support member 311 and the relief groove 3121 are provided with a relief space 3122 at the position opposite to the relief groove 3121. The relief space 3122 is connected to the relief groove 3121.

[0035] Reference Figure 2 and Figure 5 The lifting component 41 can enter and exit the clearance space 3122, thereby enabling it to lift or place the weight 5 along the height direction. The design of the clearance slot 3121 and the clearance space 3122 provides operating space for the lifting component 41, facilitating the lifting and placement of the weight 5.

[0036] Reference Figure 6 and Figure 7 The multi-claw support 312 includes a tray 3123 and a support block 3124 mounted on the tray 3123. The support block 3124 has a stepped structure to accommodate weights 5 of different sizes. This stepped structure can be designed with multiple steps, each step corresponding to a different size of weight 5, so that weights 5 of different sizes can be stably placed on the support block 3124.

[0037] Reference Figure 3 and Figure 8 The top of the vacuum chamber 32 is connected to a support plate 321, and the top surface of the arc portion 411 can abut against the bottom surface of the support plate 321. The support plate 321 can be a circular metal plate, which is connected to the vacuum chamber 32 by sealant to ensure sealing performance.

[0038] Reference Figure 8 and Figure 9 The lifting component 41 includes an open arcuate portion 411 and a lifting portion 412 disposed inside the arcuate portion 411.

[0039] Reference Figure 2 and Figure 8 The shape of the arc-shaped part 411 can better fit the shape of the vacuum chamber 32 or the weight 5, making it easier to grasp and operate. The lifting part 412 has a multi-stage stepped structure 4121 with a hollow center. This design can accommodate weights 5 of different sizes while reducing the weight of the lifting part 412.

[0040] Reference Figure 8 and Figure 10 The top of the arc portion 411 is provided with a first conical inclined surface 4111, which slopes downwards towards the center of the arc portion 411. The bottom of the support plate 321 is provided with a second conical inclined surface 3211 that matches the first conical inclined surface 4111. When the lifting assembly 41 grasps the vacuum cover 32, the first conical inclined surface 4111 and the second conical inclined surface 3211 cooperate with each other to make the lifting more stable.

[0041] Reference Figure 8 The supporting part 412 is a multi-level stepped structure 4121, with a gap in the middle of the multi-level stepped structure 4121.

[0042] The implementation principle of this embodiment is as follows: The vacuum environment weight loading and transfer mechanism creates a vacuum environment through the vacuum tank 1 and the air system 2, avoiding the influence of air on the detection of the weight 5. The weight storage mechanism 3 ensures that the weight 5 is in a vacuum state before and after the detection, further guaranteeing the accuracy of the detection. The design of the gripping device 4 and the lifting assembly 41 makes the transfer and operation of the weight 5 more convenient and stable. The configuration of the first transfer seat 13 and the second transfer seat 14 facilitates the transfer of the weight 5 and the vacuum chamber 32, improves the overall operating efficiency of the equipment, and greatly improves the accuracy of the detection results compared with traditional weight 5 detection methods, meeting the requirements of high-precision detection.

[0043] Example 2 This application also discloses a method for loading and transferring weights in a vacuum environment, which uses the vacuum environment weight loading and transfer mechanism in Embodiment 1, and includes the following steps: S1 provides a weight storage mechanism 3, which contains weights 5 in a vacuum state. The weight storage mechanism 3 can pre-place the weights 5 in a vacuum environment and seal them to maintain a vacuum state. Specialized vacuum packaging equipment can be used to package the weights 5 to ensure a vacuum environment inside.

[0044] S2, Place the weight storage mechanism 3 into the vacuum container 1 and evacuate the vacuum container 1. Place the weight storage mechanism 3 into the vacuum container 1 through the conveying channel 11, close the channel gate 12, and start the vacuum pump of the air system 2 to extract the air from the vacuum container 1, achieving the required vacuum level. During the evacuation process, the vacuum level inside the vacuum container 1 can be monitored in real time using a vacuum gauge.

[0045] S3, a gripping device 4 is provided. The gripping device 4 opens the weight storage mechanism 3 and transfers the weights 5 inside to a detection device that is also under vacuum. The gripping component 41 of the gripping device 4 first grips the tray 321 on top of the vacuum chamber 32, removing the vacuum chamber 32 from the support 31 and placing it on the second transfer seat 14. Then, the gripping component 41 enters from the clearance space 3122, grips the weights 5, and transfers them to the external detection device for testing via the conveying channel 11.

[0046] S4, after the weight 5 is tested, the gripping device 4 moves the weight 5 back into the weight storage mechanism 3, and the gripping device 4 closes the weight storage mechanism 3. After the test is completed, the lifting component 41 of the gripping device 4 moves the weight 5 from the testing device back to the support 31, and then grips the vacuum cover 32 from the second transfer seat 14 and places it on the support 31, so that the weight 5 is in a vacuum state again.

[0047] S5. Introduce air into vacuum tank 1 to disrupt the vacuum environment inside. Turn off the vacuum pump and open the air inlet valve to allow air to slowly enter vacuum tank 1 until the pressure inside the tank equalizes with the external atmospheric pressure.

[0048] S6, remove the weight storage mechanism 3 from the vacuum tank 1. Open the channel gate 12 and remove the weight storage mechanism 3 from the vacuum tank 1 through the conveying channel 11.

[0049] The implementation principle of this embodiment is as follows: This vacuum-state weight 5 detection method maintains the weight 5 in a vacuum state throughout the entire detection process, avoiding the influence of air on the weight 5 detection. Each step is closely coordinated and performed in an orderly manner, ensuring the accuracy and reliability of the weight 5 detection. Compared with traditional weight 5 detection methods, this method can effectively reduce errors caused by environmental factors, meet the needs of high-precision detection, and provide a more reliable metrological foundation for industrial production and scientific research.
