Description

Technical Field

[0001] This utility model relates to the field of industrial robots, and in particular to a vacuum handling device for thin sheet materials. Background Technology

[0002] In the current manufacturing environment, the production and processing of sheet materials plays an important role; however, traditional production lines still generally rely on manual handling when processing such materials. This model is not only inefficient and unable to meet the needs of large-scale, fast-paced production, but also makes sheet materials very susceptible to damage due to improper handling during manual operation, such as scratches, bending, or deformation, thereby affecting the final quality of the product and the company's production efficiency.

[0003] In recent years, with the continuous rise in labor costs, enterprises are facing increasingly severe cost pressures. In order to reduce production costs, improve production efficiency, and ensure product quality, production line automation has become an inevitable trend in the industry. Especially for materials such as thin sheet metal parts, which have high requirements for processing precision and efficiency, achieving automatic loading and unloading has become a key part of production line automation transformation. Automated operation can not only significantly reduce manpower requirements and lower labor costs, but more importantly, by replacing manual operation with precisely controlled mechanical devices, it can significantly reduce material damage, improve product qualification rate, and thus enhance the market competitiveness of enterprises.

[0004] In conclusion, given the low efficiency and easy damage to materials caused by manual handling of thin sheet materials, as well as the pressure brought by rising labor costs, production lines urgently need to develop automated loading and unloading technology for thin sheet parts in order to achieve high efficiency, intelligence and precision in the production process.

[0041] Please see Figures 1-3 The embodiments of this utility model include:

[0042] A vacuum handling device for thin sheet materials, comprising:

[0043] (1) A multi-axis robotic arm 1 is installed on the production line or the ground to provide support and displacement control. In this embodiment, it includes, but is not limited to, the use of a 4-axis robotic arm to achieve flexible and multi-directional displacement control. The 4-axis robotic arm supports rotation control of the A1 axis, A2 axis, and A3 axis, as well as vertical lifting control of the A3 axis. It should be noted that since the multi-axis robotic arm 1 adopts mature robot technology and is not a key component of this application, existing industrial robots with corresponding functions can be used. This does not affect the operation of the core innovative component of this application, and will not be described in detail here. Moreover, since the multi-axis robotic arm 1 is a mature technology in this field, its internal structure will not be shown in the accompanying drawings.

[0044] (2) Thin plate adsorption module, horizontally installed at the end of the multi-axis robotic arm 1, is capable of vacuum adsorption of thin plate material 10. This module is the core innovative structure of this application, and its specific structural components are as follows:

[0045] (2.1) Connecting seat 2, vertically installed at the end of the multi-axis robotic arm 1, is used to connect with subsequent components;

[0046] (2.2) The material suction cup 3 is horizontally connected to the bottom of the connecting seat 2 at its center. The material suction cup 3 is rectangular and has a hollow mesh structure, on which several suction nozzles 4 are fixed.

[0047] (2.3) Suction nozzles 4 are evenly distributed on the material suction cup 3 and are all set vertically downwards; in this embodiment, there are 20 suction nozzles 4, which are arranged in a 4*5 pattern on the material suction cup 3; specifically, for each suction nozzle 4, it is connected to the material suction cup 3 through a suction nozzle mounting piece 5 that is vertically embedded on the material suction cup 3. The suction nozzle mounting piece 5 is a hollow tubular connector that is directly inserted through the material suction cup 3. The upper end of the suction nozzle 4 is connected and communicates with the lower end of the suction nozzle mounting piece 5.

[0048] (2.4) Vacuum pressure gauge 6 is installed on the upper surface edge of the material suction cup 3 to detect the adsorption pressure value of the suction nozzle 4, and thus determine the adsorption status of the thin plate material 10.

[0049] (2.5) Vacuum manifold 7 is set on the upper surface of the material suction cup 3 and located on both sides of the connecting seat 2. Several manifold ports are provided on both sides of the vacuum manifold 7, which are similar to airflow collection and transfer stations. They are used to connect the output end of the vacuum generator to several suction nozzles 4 respectively. Therefore, one end of the vacuum manifold 7 is connected to the upper end of the suction nozzle mounting part 5 connected to the upper end (air inlet end) of several suction nozzles 4 through air pipes 11 respectively. The other end of the vacuum manifold 7 is connected to the vacuum generator set in the near multi-axis robotic arm 1 through air pipes 11. Under the action of the vacuum generator, the suction nozzles 4 are controlled to realize the vacuum adsorption function. It should be noted that since the specific installation position of the vacuum generator and vacuum pressure gauge 6 does not affect the operation of the key components of this device, and the vacuum generator and vacuum pressure gauge 6 are not the core functional components of this application, the vacuum generator and vacuum pressure gauge 6 in the prior art can be used. Therefore, they are not shown in the attached drawings of this application and will not be described in detail.

[0050] (2.6) The material plate sensor 8 is installed on the hollow part of the material suction cup 3 through the sensor connector 9. The lower end of the material plate sensor 8 is flush with the lower end of the suction nozzle 4. It is used to detect whether the multi-axis robotic arm 1 controls the material suction cup 3 to descend into place when picking up and discharging materials.

[0051] Based on the above structure, this device can achieve fully automatic adsorption of micro-thin sheet materials 10, and can realize vacuum material handling and positioning of micro-parts; in one embodiment, the working principle of this device is as follows:

[0052] During material handling, the multi-axis robotic arm moves the material handling suction cup 3 to the material handling position and then descends;

[0053] After the material plate sensor 8 senses the thin plate material 10, it stops descending. At this time, the vacuum generator runs and the 20 vacuum nozzles 4 of the material suction cup 3 suck up the thin plate material 10.

[0054] Once the vacuum pressure gauge 6 reaches the preset value, the multi-axis robotic arm 1 controls the material suction cup 3 to lift and move to the discharge position, and controls the material suction cup 3 to descend there; after the material plate sensor 8 senses the position again, the multi-axis robotic arm 1 controls the material suction cup 3 to stop descending. At this time, the vacuum generator stops operating, the plate material is placed into the discharge position, and the unloading action is completed.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
