[0027] like Figure 1-5 As shown, this utility model provides an automatic unloading device for vehicle cover plates, including a grid-shaped aluminum profile frame 1, multiple adjustable suction cups 2, and a negative pressure connection system 3;

[0028] The center of the grid-shaped aluminum profile frame 1 is provided with a robotic arm mounting interface 11, which is connected to the end effector of the industrial robotic arm through a nut adapter.

[0029] The frame 1 has regularly distributed mounting holes 12 on its four sides, and the suction cup 2 can be detachably mounted on the holes using mounting accessories.

[0030] The negative pressure connection system 3 includes:

[0031] The air passage 31 located inside the frame 1 is connected at one end to the interface of each suction cup 2;

[0032] The flexible air tube 32 connects the airway 31 to the negative pressure generator 4 through the sealing joint 33, ensuring negative pressure transmission and maintaining the flexibility of the robotic arm's movement.

[0033] The grid-shaped aluminum profile frame 1 provides a stable foundation for the installation of the suction cup 2. The regularly distributed mounting holes 12 on the four sides of the frame 1 allow the suction cup 2 to be flexibly adjusted according to the different sizes and shapes of vehicle covers, ensuring that the suction cup 2 can be accurately aligned with the surface of the cover and achieve precise positioning and adsorption.

[0034] The design of multiple adjustable suction cups 2 increases the contact area with the cover plate, providing stronger suction force and ensuring that the cover plate will not slip or shake during the unloading process. This improves the stability and reliability of unloading and effectively avoids equipment damage or safety accidents caused by the cover plate falling off.

[0035] The air passage 31 in the negative pressure connection system 3 is located inside the frame 1, with one end connected to the interface of each suction cup 2. It can transmit the negative pressure generated by the negative pressure generator 4 evenly and stably to each suction cup 2, ensuring that the suction cup 2 can continuously and effectively adsorb the vehicle cover.

[0036] The flexible air tube 32 connects the airway 31 to the negative pressure generator 4 through the sealing joint 33. This design ensures the transmission of negative pressure without imposing too many restrictions on the movement of the robotic arm, enabling the robotic arm to flexibly perform movements at various angles and positions to complete complex unloading tasks, thus improving the applicability and flexibility of the device.

[0037] See Figure 3 The mounting holes 12 are evenly distributed in an array on the four sides of the grid-shaped frame 1, and the number and installation position of the suction cups 2 are dynamically adjusted according to the size of the vehicle-mounted product.

[0038] There are many types of vehicle-mounted products, and the size of vehicle covers varies greatly depending on the vehicle model and location. The array of evenly distributed mounting holes 12 provides a rich and regular selection of mounting points for the suction cups 2. By dynamically adjusting the number and position of the suction cups 2, the device can be adapted to vehicle covers of various sizes. There is no need to customize unloading equipment for products of different sizes, which greatly improves the versatility of the device and reduces production costs.

[0039] Besides size differences, some vehicle covers may have irregular shapes. This flexible suction cup 2 layout can be used to install the suction cups 2 in the position that provides the most stable suction force according to the actual shape of the cover, ensuring effective gripping and unloading of covers with special shapes, and further expanding the applicability of the device.

[0040] Dynamically adjusting the number and position of suction cups 2 according to the size of the vehicle-mounted product allows for a more rational distribution of suction cups 2 on the cover surface, thereby optimizing the distribution of adsorption force. For larger covers, increasing the number of suction cups 2 and distributing them rationally can provide a more uniform and powerful adsorption force, preventing the cover from slipping or deforming during the removal process due to uneven local force. For smaller covers, appropriately reducing the number of suction cups 2 and adjusting their positions can ensure sufficient adsorption force while avoiding operational inconvenience or increased costs due to an excessive number of suction cups 2.

[0041] See Figure 1 A limiting block 6 is provided in the mounting hole 12, and a connecting block 5 with two through holes is provided above the limiting block 6. One hole of the connecting block 5 is connected to the limiting block 6 by a bolt 7, and the other hole is fixedly connected to the suction cup 2. The top support column of the suction cup 2 passes through the through hole of the connecting block 5 and is fixed with a nut.

[0042] See Figure 4 The robotic arm mounting interface 11 is a universal threaded nut structure, which is compatible with the end flange of robotic arms on the market.

[0043] The sealing joint 33 and the flexible air tube 32 form a sealed connection that can be quickly disassembled and assembled to prevent negative pressure leakage.

[0044] See Figure 2 The cross-section of the internal air passage 31 of the grid-shaped aluminum profile frame 1 is a through-type channel, covering the entire suction cup 2 installation area.

[0045] See Figure 1 The suction surface of the suction cup 2 faces downwards from the frame 1. When the negative pressure generator 4 is activated, it synchronously transmits negative pressure to the suction cup 2 through the air passage 31.

[0046] See Figure 5 The negative pressure generator 4 includes an intake duct 45 and an exhaust duct 46 connected in a straight line, and an intake duct 44 connected on the side. The intake duct 45 is provided with a nozzle 41, a mixing chamber 42 behind the nozzle 41, and a diffuser 43 behind the mixing chamber 42.

[0047] The negative pressure generator 4 is based on the Venturi effect and generates negative pressure through high-speed airflow: Compressed air drive: Compressed air is ejected at high speed from nozzle 41. According to Bernoulli's principle, the increase in flow velocity leads to a decrease in pressure. The high-speed airflow forms a low-pressure zone at the outlet, and the surrounding air is drawn in to form a stable negative pressure.

[0048] Air inlet: Connects to compressed air;

[0049] Nozzle 41: The constricted channel accelerates the airflow, forming a high-speed jet;

[0050] Mixing chamber 42: Draws in ambient air and mixes it with the main airflow;

[0051] Diffuser: slows down airflow, recovers energy, and outputs negative pressure;

[0052] Vacuum port: Connects to actuators such as suction cup 2, and outputs negative pressure.

[0053] Airflow direction: Compressed air → Nozzle 41 (high-speed jet) → Mixing chamber 42 (air entrainment) → Diffuser (forming negative pressure) → Vacuum port.
