Under negative pressure suction and handling vibrations, the seals are prone to detaching from the support, leading to air leakage and sheet metal slippage. This severely impacts the stability and safety of laser cutting machine loading. Therefore, there is an urgent need for a sheet metal handling device with a secure seal and effective anti-detachment and anti-slip properties. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :

[0025] Example 1:

[0026] This embodiment provides a sheet metal handling device, including a frame 1, a mounting bracket 2 disposed on the frame 1, and a plurality of vacuum suction cups 3 connected below the mounting bracket 2. The vacuum suction cups 3 include:

[0027] The rigid support base 4 has a sealing groove 5 at its bottom;

[0028] A soft sealing body 6 is disposed in the sealing groove 5 of the rigid support base 4;

[0029] The limiting structure 7 is provided inside the sealing groove 5 to restrict the soft sealing body 6 from falling out;

[0030] An anti-slip reinforcement structure 8 is provided on the soft sealing body 6 to prevent the transported object from slipping and falling off.

[0031] This sheet material handling device includes a frame 1, a support arm, an electric actuator, a mounting frame 2, and multiple vacuum suction cups 3. The frame 1 is the vertical load-bearing frame of the whole machine. The support arm is fastened to the upper part of the frame 1 with bolts, and the support arm extends horizontally towards the material working side. The upper end of the cylinder of the electric actuator is connected to the extension end of the support arm through a flange and bolts. The telescopic end of the electric actuator is vertically downward and is connected to the center of the upper end face of the mounting frame 2 through a threaded connection. When the electric actuator telescopically moves, it can drive the mounting frame 2 to move vertically up and down. Multiple vacuum suction cups 3 are evenly arranged in a matrix. The upper end of each vacuum suction cup 3 is screwed and fixed to the lower end face of the mounting frame 2 through a threaded joint. The vacuum generating device is installed in the lower space of the frame 1 by bolts. The main gas supply pipe is fixed to the outer wall of the support arm and the electric push rod by pipe clamps. After the end of the main gas supply pipe extends to the position of the mounting frame 2, it branches out into a corresponding number of gas supply branches through a multi-port connector. The end of each gas supply branch is sealed to the upper air inlet of the vacuum suction cup 3 through a compression fitting. The negative pressure airflow can be stably delivered to each vacuum suction cup 3 through the pipeline.

[0032] The rigid support base 4 serves as the main support for the vacuum suction cup 3. It is made of aluminum alloy or rigid engineering plastic. This material has structural rigidity and is not easily deformed under stress, thus maintaining the overall shape of the vacuum suction cup 3 stably. The rigid support base 4 is located on the upper part of the vacuum suction cup 3. Its bottom is integrally formed with a sealing groove 5. The sealing groove 5 and the rigid support base 4 are integrally formed from the same material. There is no gap between them and their relative positions remain fixed. The axial section of the sealing groove 5 is C-shaped, and the groove opening is vertically downward, used to accommodate and assemble the soft sealing body 6.

[0033] The rigid support base 4 has a vacuum channel inside. The upper end of the vacuum channel is connected to the gas supply branch pipe, and the lower end extends into the interior of the sealing groove 5, so that the negative pressure airflow can enter the adsorption space enclosed by the soft sealing body 6 and the material through the vacuum channel.

[0034] The soft sealing body 6 is made of nitrile rubber or liquid silicone. This material has good flexibility and elasticity, and can conform to the contour of the material surface to produce adaptive deformation, ensuring a sealing fit effect. The outer contour of the soft sealing body 6 matches the inner contour of the sealing groove 5. The whole body is clamped into the sealing groove 5 in an interference fit manner. The outer side wall of the soft sealing body 6 is completely fitted with the inner side wall of the sealing groove 5. The bottom of the soft sealing body 6 extends downward into the sealing groove 5 to contact the material surface and enclose it to form a closed negative pressure adsorption space.

[0035] Limiting protrusions 70 are integrally formed on two opposite inner sidewalls of the sealing groove 5. Multiple limiting protrusions 70 are provided, and the whole is arc-shaped and evenly distributed along the circumference of the sealing groove 5. The limiting protrusions 70 are integrally formed with the sealing groove 5, with the protruding end facing the inside of the sealing groove 5 and pressing against the outer sidewall of the soft sealing body 6. The axial locking and limiting of the soft sealing body 6 is achieved by the compression and constraint of the arc-shaped protrusion, so as to prevent the soft sealing body 6 from falling out of the sealing groove 5 during negative pressure adsorption or transportation vibration.

[0036] The soft sealing body 6 can rely on its own elastic deformation to break free from the constraint of the limiting protrusion 70 under external prying force and be taken out from the sealing slot 5, so as to achieve individual replacement without disassembling other parts of the vacuum suction cup 3.

[0037] The soft sealing body 6 contains anti-slip particles 80, which are made of glass microspheres or alumina particles and are integrally formed with the soft sealing body 6 through a molding and blending process. The anti-slip particles 80 are uniformly wrapped inside the material of the soft sealing body 6, forming a gapless integral structure with the soft sealing body 6. When the soft sealing body 6 is in contact with the material surface and is deformed under pressure, the anti-slip particles 80 inside will conform to the deformation of the soft sealing body 6, abut against and embed into the micro-concave and convex gaps on the material surface, increase the static friction resistance between the soft sealing body 6 and the material, limit the lateral sliding of the material relative to the vacuum suction cup 3, and thus prevent the material from falling off during the transfer process.

[0038] During operation, the electric actuator pushes the mounting frame 2 and the vacuum suction cup 3 below it downwards through its telescopic movement, causing the soft sealing body 6 at the bottom of the vacuum suction cup 3 to fit tightly against the surface of the material to be transferred. The vacuum generator is activated, drawing air from inside the vacuum suction cup 3 through the main and branch gas supply pipes, creating a negative pressure adsorption environment inside the suction cup. Under the negative pressure, the soft sealing body 6 further adheres to the material surface. The interference fit structure between the sealing groove 5 and the soft sealing body 6, combined with the axial locking effect of the limiting protrusion 70, ensures that the soft sealing body 6 is always stably assembled in the sealing groove 5. The anti-slip particles 80 inside the soft sealing body 6 are pressed into the micro-gaps on the material surface, increasing frictional resistance and preventing material slippage. The integral molding structure of the rigid support base 4 and the sealing groove 5 ensures the overall stability of the vacuum suction cup 3. The electric actuator drives the adsorbed material to rise and transfer, completing a stable handling operation.

[0039] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
