Abstract
Description
Technical Field
[0001] This application relates to the field of transfer devices, and in particular, to an airbag-wrapped transfer device for thin-walled pipe fittings. Background Art
[0002] In the prior art, the grasping and transfer of pipe fittings mainly rely on rigid structures such as mechanical claws and fixtures. These mechanical grippers achieve grasping and handling by directly applying mechanical force to the surface of the pipe fittings. During the traditional transfer process, in order to ensure the stability of the pipe fittings during handling and prevent them from falling, a relatively large mechanical clamping force usually needs to be applied. However, due to their relatively fragile structural characteristics, thin-walled pipe fittings are prone to producing indentations or permanent deformations when subjected to large mechanical forces. Especially for thin-walled pipe fittings used in the new energy field, they have a relatively thin wall thickness and complex shapes, such as triangular and other special-shaped pipe fittings. The above problems significantly affect the appearance quality and mechanical properties of the pipe fittings, becoming a bottleneck in the application of traditional mechanical grippers.
[0003] New energy equipment usually has relatively high requirements for heat dissipation performance. Therefore, thin-walled pipe fittings are widely used in heat conduction and cooling systems. The geometric shapes of these pipe fittings are diverse and complex, often adopting special-shaped cross-sections in order to optimize the heat dissipation effect or adapt to limited installation space. However, traditional rigid mechanical grippers cannot effectively handle the complex shapes of these special-shaped pipe fittings, and the directly applied mechanical force is prone to causing local stress concentration, resulting in irreversible deformation of the pipe fittings during grasping and handling. This stress concentration problem not only weakens the mechanical strength of the pipe fittings but also reduces their heat dissipation efficiency, and even causes the failure of the pipe fittings in severe cases. This situation is particularly significant in production processes with high-precision and high-reliability requirements. The use of traditional mechanical claws and fixtures may cause instability in product quality, increasing production costs and the rejection rate.
[0004] In addition, when traditional mechanical claws and fixtures handle complex pipe fittings, there are also problems of complex operation and poor adaptability. Since thin-walled pipe fittings may have different sizes and shapes, traditional mechanical grippers need to be adjusted and reset frequently when facing these pipe fittings to adapt to different types of pipe fittings. This adjustment process is time-consuming and laborious, not only affecting production efficiency but also increasing the maintenance cost of the equipment. Especially in a large-scale production environment, frequent equipment adjustment may lead to the interruption of the production process, reducing the efficiency and reliability of the overall production line. In order to reduce this complexity, some production lines have tried to use flexible manipulators for improvement, but such equipment also faces limitations of high cost and complex control.
[0005] The deformation and indentation problems of thin-walled pipes are also closely related to the properties of the materials. These thin-walled pipes are usually made of aluminum alloys, stainless steel and other materials. These materials themselves have high thermal conductivity, but due to their thin-wall characteristics, they are prone to yield deformation under external forces. Especially in the field of new energy, these pipes need to ensure their thermal conductivity and overall structural strength to maintain the stable operation of the equipment. Therefore, how to apply appropriate pressure to the pipes during the grabbing and transfer process to avoid indentation and deformation has become a problem that needs to be solved in this field.
[0006] In view of the above-mentioned shortcomings, it is particularly important and valuable to develop a new type of transfer device. Utility Model Content
[0007] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide an airbag gripping and transferring device for thin-walled pipes. The transfer device adopts an airbag inflation gripping method to apply uniform pressure during the process of grasping and transferring thin-walled pipes, thereby effectively avoiding the indentation and deformation problems caused by traditional rigid mechanical grippers. This uniform pressure application method effectively protects the integrity of the pipes and is particularly suitable for thin-walled and complex-shaped pipes.
[0008] To achieve the above-mentioned purpose, the present application discloses an airbag-wrapped gripping transfer device for thin-walled pipe fittings, the transfer device comprising a driving assembly, an air-gripping clamping assembly connected to the driving assembly and driven by the driving assembly, wherein the air-gripping clamping assembly comprises a 冂-shaped frame with an open lower end, two upper spherical airbags installed at the left and right inner corners of the frame, and two lower C-shaped airbags symmetrically installed on the two inner sides of the frame and close to the open surface of the lower frame; the two spherical airbags cooperate with the two C-shaped airbags to form a gripping position; when the C-shaped airbag is inflated, it completely / partially blocks the open end surface of the frame.
[0009] In some embodiments, the two spherical airbags are independently connected to an external high-pressure gas source through pipelines with control valves.
[0010] In some embodiments, the two C-shaped airbags are independently connected to an external high-pressure air source through pipelines with control valves.
[0011] In some embodiments, the C-shaped airbag portion is bonded to the side surface of the frame.
[0012] Compared with the prior art, the present invention has at least one of the following beneficial effects:
[0013] 1. Improve the grasping stability of pipe fittings: The airbag inflation grip method can better wrap the pipe fittings, improve the stability during grasping, and reduce the risk of falling.
[0014] 2. Adapt to various pipe fitting shapes: The spherical airbag and C-shaped airbag in the device are flexibly designed and can adapt to pipe fittings of different shapes and sizes, especially suitable for pipe fittings with special-shaped cross-sections.
[0015] 3. Reduce adjustment frequency: Compared with traditional mechanical grippers, the airbag-type transfer device of the present utility model does not need to be adjusted frequently, reducing the maintenance and operation complexity of the equipment and improving production efficiency.
[0016] 4. Avoid problems of pipe fitting deformation and indentation: By means of airbag wrapping, pressure is evenly applied, effectively protecting thin-walled pipe fittings, especially pipe fittings with complex shapes, and avoiding indentation and permanent deformation caused by traditional rigid mechanical grippers.
[0017] The beneficial effects listed above do not exhaust all advantages. Other potential beneficial effects and detailed technical implementation manners will be further disclosed in the embodiments or other description parts of this application. Description of the Drawings

[0026] As Figure 1 、 2 As shown, this embodiment discloses an airbag - wrapped transfer device for thin - wall pipe fittings. The overall transfer device includes a driving assembly 1 and an air - grip clamping assembly 2 driven by it. The air - grip clamping assembly 2 is composed of a U - shaped frame member 201 with an open lower end, two upper spherical airbags 202 installed at the left and right inner top corners of the frame member 201, and two lower C - shaped airbags 203 symmetrically installed on the two inner sides of the frame member 201 and close to the open surface of the frame member 201. The two spherical airbags 202 and the two C - shaped airbags 203 cooperate to jointly form a gripping position 204 for clamping the thin - wall pipe fittings. When inflated, the C - shaped airbags 203 can close the open end face of the frame member 201, effectively wrapping and fixing the thin - wall pipe fittings.
[0027] Specifically, first of all, the frame member 201 is designed with a U - shaped structure and an open lower end, enabling it to sleeved the thin - wall pipe fittings from above. The U - shaped frame member 201 is made of high - strength alloy steel and has sufficient mechanical strength to ensure that it does not deform or damage during the process of clamping and transferring the thin - wall pipe fittings. The inner sides of the frame member 201 are used to fix the C - shaped airbags 203, and the inner top corners are used to fix the upper spherical airbags 202. The upper spherical airbags 202 are arranged to achieve a large - area contact with the thin - wall pipe fittings through their arc - shaped structures, thereby effectively dispersing stress and avoiding deformation or damage of the thin - wall pipe fittings caused by excessive local pressure. This design can significantly improve the stability of clamping, enabling the pipe fittings to maintain their original shape more firmly during the clamping process.
[0028] It should be understood that the inflation pressure of the upper spherical airbag 202 can be finely adjusted according to the shape and material properties of the pipe fitting, thereby further enhancing the grasping effect and ensuring the reliability of the clamping operation. In addition, the design of the upper spherical airbag 202 also takes into account the adaptability to different pipe fittings. It can adapt to pipe fittings with different diameters and thicknesses by adjusting the inflation volume, providing a wider range of applicability. This flexibility enables the clamping system to perform excellently in dealing with different working conditions and complex process requirements, effectively reducing the problem of production efficiency decline caused by mismatched fixtures.
[0029] It should also be noted that the material selection of the upper spherical airbag 202 is also particularly important. It adopts a combination of synthetic rubber and wear-resistant coating, which not only has good elasticity and airtightness but also can maintain the stability of its performance in an industrial environment with high-frequency use.
[0030] In terms of specific air circuit connection, the upper spherical airbag 202 is connected to an external high-pressure air source through a pipe with a control valve. The two upper spherical airbags 202 are independently controlled to be independently adjusted according to the specific size and shape of the pipe fitting. The high-pressure air source provides a stable air pressure for the upper spherical airbag 202, and the size of the air pressure can be precisely adjusted according to the clamping needs, thereby ensuring the stability and safety of the pipe fitting during the clamping process.
[0031] In addition, as an optimization, in order to further enhance the stability during the clamping process, the surface of the upper spherical airbag 202 is also designed with fine anti-slip textures, which can increase the friction force during clamping and prevent the pipe fitting from sliding during the operation.
[0032] In this embodiment, the C-shaped airbags 203 are symmetrically installed on both sides of the frame member 201, and their lower ends are close to the open surface of the frame member 201. By inflating, the C-shaped airbags 203 can partially or completely enclose the open end face of the frame member 201, thereby providing all-round protection for the thin-walled pipe fitting during the transfer process. The design of the C-shaped airbags 203 aims to effectively block the open end face of the frame member as needed to ensure that the pipe fitting can maintain a stable position within the frame member 201 in a specific operating environment. The C-shaped airbags 203 are partially adhered to the inner side surface of the frame member 201 to increase their fixing strength with the frame member 201, so as to remain stable during the inflation and deflation processes. The C-shaped airbags 203 are also connected to an external high-pressure air source through a pipe with a control valve, and the two C-shaped airbags 203 are independently controlled to meet the needs of different pipe fittings. The material of the C-shaped airbags 203 is selected as a high-elastic and high-temperature-resistant composite rubber, which enables it to still maintain excellent performance in a high-temperature working environment and avoid affecting the sealing effect and stability of the airbag due to environmental temperature changes.
[0033] During use, first, the driving component is used to move the frame part downward above the thin-walled pipe fitting, and the thin-walled pipe fitting is received from the open surface. Then, the upper spherical airbag 202 and the lower C-shaped airbag 203 are inflated respectively. As Figure 3 shown, the airbag wraps the thin-walled pipe fitting, thereby realizing the grasping and fixing of the pipe fitting. The inflation process of the airbag is precisely adjusted by the control system, and the opening and closing of the control valve are used to control the air pressure to achieve stable clamping of the thin-walled pipe fitting. Subsequently, the frame part is driven by the driving component 1 to move the thin-walled pipe fitting to the target position. The entire operation process is characterized by high automation, adjustable clamping force, and excellent protection effect on the pipe fitting. During the inflation process, the control system monitors the pressure change in the airbag in real time through sensors to ensure that the air pressure remains stable within the predetermined range. When the thin-walled pipe fitting reaches the target position, the control system will instruct the airbag to deflate, enabling the pipe fitting to be released smoothly and enter the next operation. The entire process realizes fully automated operation, effectively reducing the need for manual intervention and the possibility of misoperation.
[0034] In specific usage scenarios, for example, when the thin-walled pipe fitting needs to be transferred between processing lines, the transfer device can wrap and hold the thin-walled pipe fitting through the airbag to ensure that it will not slide or fall during the transfer process. Compared with traditional mechanical clamps, the airbag-wrapping transfer device can achieve more flexible adjustment according to the shape and size of the pipe fitting, avoiding deformation or damage of the pipe fitting caused by excessive clamping force. Especially in the transfer of some thin-walled pipe fittings that are easily deformed by force, the airbag clamping can provide good support and protection, significantly improving the safety of operation and the reliability of transfer. For thin-walled pipe fittings that need to be transferred and processed multiple times, the device can quickly adjust the clamping parameters between different processes, ensuring the integrity and quality of the pipe fitting throughout the production process. At the same time, the flexible design of the airbag clamping system makes it particularly suitable for application scenarios with high surface requirements for thin-walled pipe fittings, avoiding surface indentations or damages that may be caused by rigid clamping.
[0035] In addition, the airbag - wrapped transfer device of this embodiment has demonstrated extremely high adaptability and efficiency in industrial automated production lines. For example, in the production processes of automobile manufacturing, aerospace, and precision electronic devices, the transfer of thin - walled pipe fittings requires relatively high precision and gentle clamping methods. The airbag - wrapped transfer device can achieve flexible clamping force control, thus effectively avoiding structural deformation caused by excessive clamping. At the same time, the high degree of automation of this device enables it to be seamlessly connected with existing automated control systems, thereby realizing the intelligent control of the production line. In addition, this device also has high adaptability. By finely controlling and adjusting the air pressure, it can adapt to thin - walled pipe fittings of different specifications and materials, making its application in industrial production more extensive. In the above - mentioned manner, the airbag - wrapped transfer device not only improves the safety and reliability of the transfer operation, but also greatly enhances the flexibility and intelligent level of the production line.
[0036] In summary, through the detailed design of the airbag - wrapped clamping system in this embodiment, an efficient solution applicable to the transfer of thin - walled pipe fittings is provided. This solution has significant advantages in improving clamping reliability, protecting the integrity of thin - walled pipe fittings, and enhancing the degree of industrial automation. Through precise air pressure control, multiple safety protection mechanisms, and flexible adaptability to pipe fittings, the device can handle various complex industrial application scenarios, thus greatly improving production efficiency and product quality. In addition, the flexible characteristics of the airbag clamping method make it have broad application prospects in future intelligent manufacturing and flexible production.
