Description

Technical Field

[0001] The utility model relates to a vacuum suction device, belonging to the technical field of mechanical equipment. Background Art

[0002] During the production process on an assembly line, workpieces are processed on different lathes to complete different machining operations. When multiple machining processes are involved, the workpieces need to be transferred. In the prior art, mechanical claws are generally used to transfer workpieces to save labor costs. However, the surfaces of some workpieces are complex, and some workpiece materials are fragile, making it difficult to complete the transfer through the clamping and fixing method of mechanical claws.

[0003] For this reason, a suction cup type fixture is provided in the prior art. A plurality of suction cups are distributed in a dot matrix on the contact surface with the workpiece. By bringing the suction cups into contact with the workpiece to form a vacuum cavity for adsorption and fixation, it can adapt to the fixation of non-standard shaped workpieces, and its fixation method does not rely on clamping and is friendly to workpieces with fragile materials.

[0004] However, the existing suction cup type fixture has low vacuum generation efficiency and weak vacuum suction force, which easily causes the workpiece to fall off. Summary of the Invention

[0005] In view of this, the utility model provides a vacuum suction device, which actively provides a vacuum environment to clamp the workpiece by setting a vacuum generating device, improves the vacuum efficiency, and greatly reduces the risk of workpiece falling off.

The vacuum generating devices corresponding to the number of cavities are arranged on the outer wall of the body and communicated with the cavities. The cavities extend towards the lower bottom surface of the body to form a plurality of through holes, and suction cup assemblies are arranged on the through holes. The suction cup assemblies include corrugated suction cups.

[0008] Based on the above technical solution, the utility model can be further improved as follows.

[0009] Further, the suction cup assembly further includes a valve, and the valve is a check valve or a throttle valve. The check valve or the throttle valve is arranged between the through hole and the corrugated suction cup.

[0010] Further, the body is linear or "L"-shaped. When the body is "L"-shaped, a stabilizing rod is arranged on the outer wall of the body.

[0011] Further, a "T"-shaped fixing groove is formed on the upper end surface of the body, or a buffer rod is arranged on the upper end surface of the body.

[0012] Further, a silencer is arranged at the exhaust end of the vacuum generating device.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The present utility model is provided with a vacuum generating device, and an active vacuum chuck is adopted to realize the suction of workpieces, avoiding the problem that the traditional suction cup structure has poor adsorption and is prone to workpiece detachment. Moreover, a check valve or a throttle valve is provided to optimize the adsorption efficiency, making the adsorption more stable. The structure is simple, easy to use, and has higher efficiency.

[0021] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0022] The vacuum suction device includes a body 01, which is formed by processing profiles and has multiple cavities formed inside;

[0023] A plurality of vacuum generating devices 02 corresponding to the cavities in number are provided on the outer wall of the body 01 and are communicated with the cavities. The vacuum generating device 02, that is, a vacuum generator, is a small vacuum component that uses a positive pressure gas source to generate negative pressure. When in use, it is externally connected to a positive pressure gas source, and the on-off of the gas source is controlled by the solenoid valve of the machine to realize the generation and stop of negative pressure. It can generate a larger vacuum flow under the condition of lower gas consumption and can meet different vacuum flow requirements. The vacuum generating device 02 can be installed by opening G1 / 4 threads on the upper end face or the outer side wall of the body 01 for bolt connection;

[0024] Multiple suction cup assemblies 03. The cavity extends towards the lower bottom surface of the main body 01 to form multiple through holes. The suction cup assemblies 03 are arranged on the through holes and include corrugated suction cups 31. The structure of the corrugated suction cups 31 can form a certain buffer when the suction tool contacts the workpiece, reducing the extrusion of the suction tool on the workpiece and avoiding damage to the workpiece.

[0025] In another embodiment of the present utility model, the suction cup assembly 03 further includes a valve 32. The valve 32 is a check valve or a throttle valve. The check valve or the throttle valve is arranged between the through hole and the corrugated suction cup 31. During the process of grasping the workpiece, it can avoid the influence on the entire vacuum system due to the suction cup not adsorbing the workpiece or suddenly falling off after adsorbing the workpiece. After setting the above structure, the corrugated suction cup 31 is isolated from the vacuum system, ensuring that the vacuum degree and flow rate in the entire vacuum system will not be lost. It is particularly suitable for repeatedly grasping workpieces of different sizes in a vacuum system. The installation of the structure can be to open M5 threaded holes on the lower end face of the main body 01 for threaded connection.

[0026] In another embodiment of the present utility model, the main body 01 is linear or "L"-shaped. When the main body 01 is "L"-shaped, a stabilizing rod 11 is arranged on the outer wall of the main body 01.

[0027] In another embodiment of the present utility model, a "T"-shaped fixing groove 12 is opened on the upper end face of the main body 01 to install an "I"-shaped fixing block for connection with a robotic arm;

[0028] Or, a buffer rod 13 is arranged on the upper end face and is connected to the robotic arm through the buffer rod 13. A bushing and a compression spring are arranged on the buffer rod 13. During the clamping of the workpiece, the working stroke of the bushing and the compression spring forms a certain buffer, avoiding damage to the workpiece caused by excessive pressure when sucking the workpiece. The installation of the buffer rod 13 can be to open G3 / 8 threads on the upper end face of the main body 01 for threaded connection.

[0029] In another embodiment of the present utility model, a silencer 21 is arranged at the exhaust end of the vacuum generating device 02, which can greatly reduce the product noise.
