Description

Technical Field

[0001] This application relates to the field of article handling technology, and in particular to a vacuum environment weight loading and transfer device. Background Technology

[0002] The field of weight transportation technology has developed rapidly in recent years. With the increasing demand for weights in industrial production and metrology, efficient, safe and accurate weight transportation methods are becoming increasingly important.

[0003] In existing technologies, there are two main conventional methods for transportation. One is using conveyor belts, which enables continuous flow of weights and improves transportation efficiency to some extent. By placing weights on the conveyor belt and using the movement of the belt to propel the weights forward, large-scale rapid transportation of weights can be achieved. Another common method is to place weights on pallets for transportation. Pallets can be customized according to the size and quantity of weights, facilitating the centralized transportation of weights of different specifications. However, the handling of weights in this method mostly involves clamping.

[0004] However, existing transportation methods have significant drawbacks. In particular, the clamping method often involves the grippers making hard contact with the surface of the weight and applying a certain force to keep it clamped and prevent it from falling. This method inevitably damages the weight, which in turn affects the accuracy of subsequent weight measurements and cannot meet the requirements for high-precision weight measurements. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a vacuum environment weight loading and transfer device, which, through the unique design of the support component and the cooperation of the drive mechanism, enables stable and precise lifting or lowering of weights along the height direction.

[0006] This application is achieved through the following technical solution: A vacuum environment weight loading and transfer device, comprising: The support assembly includes a connecting ring with an opening and a plurality of support portions circumferentially distributed around the central axis of the connecting ring; A drive mechanism, the output end of which is connected to the support component, is used to drive the support component to move so that the support part supports or releases the weight along the height direction.

[0007] By adopting the above technical solution, the drive mechanism controls the lifting and lowering of the supporting component, enabling precise, stable, and repeatable lifting or placement of weights. Compared to manual handling, this method avoids shaking, tilting, contamination, and accidental damage to the weights caused by human operation, significantly improving the accuracy, stability, and efficiency of the weight weighing and calibration process. It provides the basic execution module for the entire automated weighing device.

[0008] Optionally, the support portion has at least two stepped support levels, with the diameter of the support space formed by the support levels increasing sequentially from bottom to top.

[0009] By adopting the above technical solution, the versatility and compatibility of the device are greatly enhanced. The same lifting device can be adapted to different sizes and specifications of weights within a set without replacing any parts. As the device rises, it attempts to contact the bottom of the weights step by step until it finds the support level with a matching diameter, thus achieving the gripping of different weights. This simplifies the mechanical structure, reduces device costs, and improves work efficiency.

[0010] Optionally, the connecting ring is connected to the side near the support level via an inclined surface to guide the weights placed on the support level.

[0011] By adopting the above technical solution, the fault tolerance and positioning accuracy are improved. Even if there is a slight alignment error between the weight and the support component, when the support component rises, the edge of the weight will first contact the inclined surface and automatically slide to the correct center position of the support stage under the guidance of the inclined surface. This protects the weight and the device, avoiding hard collisions, scratches, or jamming caused by misalignment, ensuring a smooth and safe loading and unloading process, and is crucial for protecting the surface integrity of high-precision weights.

[0012] Optionally, it also includes a first support member, the end of which away from the support base is connected to a multi-claw support member for supporting weights. The multi-claw support member has a clearance groove on its periphery. The first support member has a clearance space at the position opposite to the clearance groove. The clearance space is connected to the clearance groove. The support component can enter and exit through the clearance space so as to lift or place weights along the height direction.

[0013] By adopting the above technical solution, the core technical problem of "how to lift an object that already has a support from below" is solved. It achieves a clever "substitution" process: when grasping, the "supporting part" of the supporting component rises from the gap in the storage bracket, contacts and lifts the weight, causing the weight to detach from the storage bracket; when placing, the reverse is true. This design allows the weight's support to seamlessly switch between a "static storage bracket" and a "dynamic lifting device," making it a key structural design for achieving automated retrieval and placement processes.

[0014] 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.

[0015] By adopting the above technical solutions, the consistency and stability of the device are ensured. The static storage rack also adopts a stepped structure, which can stably and centrally place weights of different sizes. This provides good initial conditions for the subsequent precise grasping of the "support component". If the weights are stable and centered during storage, the working difficulty of the grasping device will be greatly reduced, and the success rate will be higher.

[0016] Optionally, the support portion includes three parts, which are evenly distributed circumferentially around the central axis of the connecting ring.

[0017] By adopting the above technical solution, the most stable and economical support is achieved. Using three support points ensures that the weight is supported smoothly without swaying or tilting.

[0018] Optionally, the connecting ring and the supporting part are integrally formed.

[0019] By adopting the above technical solutions, the overall rigidity, strength, and precision of the structure are improved. The absence of welding and screw connections avoids precision degradation caused by loose connections, deformation, or gaps. It ensures a high degree of consistency and stability in the relative dimensional positions of each supporting component, which is crucial for precise support. Simultaneously, it simplifies the assembly process and improves production efficiency.

[0020] Optionally, the support stage has a wear-resistant material layer on the surface that comes into contact with the weight.

[0021] By employing the above technical solution, high-precision weights are protected. Standard weights require extremely high quality and surface finish; any scratch or minute material transfer can lead to a change in their mass and failure. The wear-resistant layer minimizes wear on the weights, extending the service life of the lifting device itself and reducing maintenance costs caused by wear.

[0022] Optionally, the end of the connecting ring away from the support portion is provided with a handle that connects to the output end of the drive mechanism.

[0023] By adopting the above technical solution, a clear and reliable connection point is provided, facilitating the docking of the drive mechanism's output end. This design simplifies installation and maintenance, allowing the support component to be easily disassembled or replaced as a standalone module.

[0024] Optionally, the support portion has a positioning hole on the side near the handle for fixing to an external device.

[0025] By adopting the above technical solution, a positioning hole for fixing to an external device is provided on the side of the support near the handle, which allows the weight holding device to be firmly connected to the external device. This allows the positioning hole to be matched with a pin or other component on the external device, thereby enabling the component to be fixed by the support and transported.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a drive mechanism to move the support component, so that the support part can support or release the weight along the height direction, avoiding operational errors and weight contamination caused by direct manual handling, and improving the stability and accuracy of weight placement; 2. This application has at least two stepped support levels in the support section, and the diameter of the support space formed by the support levels from bottom to top increases sequentially, which can accommodate weights of different specifications and solves the problem of poor adaptability of simple clamps to weights of different specifications. 3. This application uses a connecting ring to connect to the side near the support level via an inclined surface, which can guide the weight to be placed on the support level, making the weight lifting and releasing operation more flexible and enabling accurate support and release along the height direction.

[0029] The following will be combined with the appendix Figure 1-5The 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] Reference Figures 1-2 This application discloses a vacuum environment weight loading and transfer device, including a support component 1 and a drive mechanism 2. The support component 1 includes a connecting ring 11 with an opening and a plurality of support parts 12 distributed circumferentially around the central axis of the connecting ring 11. The output end of the drive mechanism 2 is connected to the support component 1 and is used to drive the support component 1 to move so that the support parts 12 support or release the weight along the height direction.

[0031] Specifically, the connecting ring 11 is typically a ring structure, with an opening designed to facilitate compatibility with externally designed support components for supporting weights, thus adapting to specific application scenarios. The connecting ring 11 can be made of metal materials, such as stainless steel, offering good strength and corrosion resistance; alternatively, it can be made of high-strength plastic to reduce overall weight. The drive mechanism 2 can be controlled by a robotic arm, an electric actuator, or a cylinder. Electric actuators offer advantages such as high precision and ease of control, accurately moving the support component 1; cylinders, on the other hand, feature fast response and high output force.

[0032] Reference Figure 2 The connecting ring 11 is connected to the side near the support stage 121 via a ramp 111, which guides the weight onto the support stage 121. The ramp 111 serves as a guide, allowing the weight to slide smoothly onto the appropriate support stage 121 when placed near the connecting ring 11. The inclination angle of the ramp 111 can be designed according to actual conditions, generally between 30 and 60 degrees. The surface of the ramp 111 can also be smoothed to reduce resistance when the weight slides.

[0033] Reference Figure 2 The connecting ring 11 and the supporting part 12 are integrally molded. The integrally molded structure is more robust and can reduce loosening and damage at the connection points.

[0034] Reference Figure 1 and Figure 2The end of the connecting ring 11 furthest from the support 12 is provided with a handle 112 that connects to the output end of the drive mechanism 2. The handle 112 facilitates the connection between the drive mechanism 2 and the support assembly 1, and also makes it easier for the operator to operate the device. The handle 112 can be connected to the output end of the drive mechanism 2 by means of threaded connection or snap-fit ​​connection. The connection method must be secure and reliable to prevent loosening during use.

[0035] Reference Figure 2 The support stage 121 has a wear-resistant material layer 1211 on the surface that contacts the weight. The wear-resistant material layer 1211 can be a ceramic coating, a hard alloy coating, or other material layer, but it must be able to effectively reduce the wear between the weight and the surface of the support stage 121 and extend the service life of the device.

[0036] Reference Figure 2 The support portion 12 has at least two stepped support levels 121, with the diameter of the support space 122 formed by the support levels 121 increasing sequentially from bottom to top. This stepped design allows the support portion 12 to accommodate weights of different sizes. For example, smaller weights can be placed on the lower support level 121, while larger weights can be placed on the upper support level 121. The surface of the support level 121 can be smoothed to reduce friction with the weights and prevent scratching the surface of the weights; alternatively, anti-slip textures can be provided to increase friction with the weights and improve the stability of the support.

[0037] Reference Figure 2 The support section 12 comprises three parts, which are evenly distributed circumferentially around the central axis of the connecting ring 11. This distribution allows for support of the weight from multiple directions, ensuring its stability. The even distribution of the three support sections 12 provides a more stable supporting force, maintaining the weight's balance during support. The design of the three support sections 12 ensures support stability without being overly complex, which could lead to excessive device cost or operational inconvenience.

[0038] Reference Figure 1 and Figure 2 The support portion 12 has positioning holes 123 on the side near the handle 112 for fixing to external equipment. The positioning holes 123 are used to fix the support portion 12 to the external equipment, thereby securing the external equipment to the support portion 12 and improving the operating efficiency of the device. The positioning holes 123 can be circular or square, and their size and number can be designed according to the requirements of the external equipment to achieve the purpose of fixing the external equipment to the support portion 12.

[0039] Reference Figure 3 and Figure 4It also includes a first support member 3. The end of the first support member 3 away from the support base 4 is connected to a multi-claw support member 5 for supporting the weight. The multi-claw support member 5 has a relief groove 51 on its periphery. The first support member 3 has a relief space 52 at the position opposite to the relief groove 51. The relief space 52 is connected to the relief groove 51.

[0040] Reference Figure 1 and Figure 4 The supporting component 1 can enter and exit through the clearance space 52, thus enabling the lifting or placement of weights along the height direction. The first support member 3 can be a metal rod or a high-strength plastic rod, possessing sufficient strength and rigidity to support the weight of the multi-claw support member 5 and the weights. The multi-claw support member 5 is typically composed of multiple claw-shaped structures, which can be made of elastic materials or other materials, but must be able to better adapt to weights of different shapes and sizes. The clearance groove 51 and clearance space 52 provide space for the entry and exit of the supporting component 1, allowing it to smoothly pass under the multi-claw support member 5, realizing the lifting and release of weights.

[0041] Reference Figure 2 and Figure 5 The multi-claw support 5 includes a tray 53 and a support block 531 mounted on the tray 53. The support block 531 has a stepped structure to accommodate weights of different sizes. The tray 53 can be a round or square flat plate structure to support the support block 531 and the weights. The stepped structure of the support block 531 is similar to the stepped support stage 121 of the support part 12, which can accommodate weights of different sizes and improve the versatility of the multi-claw support 5.

[0042] The implementation principle of this embodiment is as follows: the vacuum environment weight loading and transfer device drives the support component 1 to move through the drive mechanism 2, avoiding direct manual contact with the weights and reducing the possibility of contamination and damage. The stepped support level 121 design of the support part 12 allows it to adapt to weights of different specifications, improving the versatility of the device. The most critical improvement of this application lies in the ingenious cooperation between the C-shaped opening structure of the support component 1 and the clearance groove 51 and clearance space 52 of the multi-claw support part 5, enabling the dynamic lifting mechanism to work in conjunction with the static storage mechanism without interference. During lifting, the support part 12 can smoothly enter under the weight and lift it steadily, achieving seamless handover of support, thereby realizing high-precision, non-destructive automated lifting.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this application.
