Description

Technical Field

[0001] The utility model relates to the technical field of parts positioning and conveying, in particular to a vacuum adsorption device for parts positioning and conveying. Background Art

[0002] Vacuum adsorption is a technology that uses the principle of negative pressure to grab and move objects. It creates a pressure area lower than the surrounding atmospheric pressure, so that the object is adsorbed on the adsorption head. This method is often used in the processing and transfer of automotive parts.

[0003] Traditional vacuum suction devices use fixed-shape suction cups, which limits their effectiveness in handling parts of different shapes, sizes or complex surfaces. For example, for parts with irregular, multi-layered or inclined surfaces, traditional suction cups cannot provide sufficient contact and stable adsorption.

[0004] Therefore, we propose a vacuum adsorption device for parts positioning and transmission. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides a vacuum adsorption device for positioning and conveying parts, which has the following beneficial effects:

[0014] (1) A vacuum adsorption device for positioning and conveying parts is provided with a plurality of sets of retractable adsorption tentacles so that when the fixing plate moves downward, the adsorption tentacles contact and squeeze the surface of the parts. The plurality of sets of adsorption tentacles will fit and adsorb according to the outer shape of the upper end of the parts.

The plurality of sets of adsorption tentacles can disperse the pressure of the device and provide a more stable adsorption effect.

[0015] (2) This vacuum adsorption device for positioning and conveying parts has a steering component so that when the adsorption head contacts the inclined surface of the part, the pressure at the edge of the adsorption head causes the adsorption head to tilt and fit the surface of the part. This close contact improves the adsorption efficiency and safety. The automatically adjusted tilt of the adsorption head can quickly adapt to parts of various shapes and angles, thereby reducing the time for mechanical adjustment and improving overall operating efficiency.

[0027] Among them, the adsorption component 4 includes an internally hollow fixed plate 41, the top position of the fixed plate 41 is vertically connected to a connecting rod 42 fixed to the front end of the robotic arm 3, the top of the fixed plate 41 is connected to an exhaust hole 43 connected to the internal hollow space of the fixed plate 41, the exhaust hole 43 is connected to the adsorption pump through a pipeline, and the lower end of the fixed plate 41 is provided with a plurality of groups of adsorption tentacles 44 that can be extended and retracted up and down in a fan-shaped array.

[0028] When in use, the device is moved to the location where parts need to be grabbed by the transport vehicle 1, and the robot arm 3 controls the adsorption component 4 to vacuum adsorb and grab the parts. By setting up multiple sets of retractable adsorption tentacles 44, when the fixing plate 41 moves downward, the adsorption tentacles 44 contact and squeeze the surface of the parts. The multiple sets of adsorption tentacles 44 will fit and adsorb according to the outer shape of the upper end of the parts. Therefore, when the device is in use, it can not only adsorb and fix parts with flat tops, but the adsorption tentacles 44 can adapt to objects of different heights and surfaces. This flexibility allows the device to work effectively on irregular or multi-layered surfaces. Multiple sets of adsorption tentacles 44 can disperse the pressure of the equipment and provide a more stable adsorption effect.

[0029] Embodiment 2: Based on the above embodiment, Figure 3 As shown, the suction tentacle 44 includes a telescopic inner rod 441 and a telescopic sleeve rod 442, the telescopic sleeve rod 442 is vertically sleeved on the outside of the telescopic inner rod 441, and the telescopic inner rod 441 and the telescopic sleeve rod 442 are both hollow tubes, the top of the telescopic inner rod 441 is connected to a limiting ring, the outside of the telescopic inner rod 441 is sleeved with a spring 443, the top of the spring 443 is connected to the top limiting ring of the telescopic inner rod 441, the lower end of the spring 443 is connected to the top of the telescopic sleeve rod 442, the lower end of the telescopic sleeve rod 442 is connected to a suction head 444, the telescopic inner rod 441 and the telescopic sleeve rod 442 are connected with a gas hose 445, the lower end of the gas hose 445 is connected to the suction head 444, and the upper end of the gas hose 445 is connected to the internal space of the fixed plate 41.

[0030] When in use, the adsorption head 444 in each set of adsorption tentacles 44 contacts the top surface of the part, and the telescopic length of the telescopic inner rod 441 and the telescopic sleeve rod 442 is adjusted by squeezing to match the shape of the top of the part.

[0031] Embodiment 3: Based on the above embodiment, Figure 4 As shown, a steering assembly is provided at the position where the telescopic sleeve 442 is connected to the adsorption head 444.

An opening is provided in the middle of the spherical movable head 446 and the spherical movable sleeve 447 to accommodate the passage of the gas delivery hose 445.

[0032] By setting up a steering assembly, when the suction head 444 contacts the inclined surface of a part, the pressure at the edge of the suction head 444 causes the suction head 444 to tilt and fit the surface of the part. This close contact improves the suction efficiency and safety. The suction head 444 that automatically adjusts its tilt can quickly adapt to parts of various shapes and angles, thereby reducing the time for mechanical adjustment and improving overall operating efficiency.

[0033] Embodiment 4: Based on the above embodiment, Figure 5 As shown, the adsorption head 444 is a trumpet-shaped structure made of rubber material, and a plurality of groups of annular rubber rings 448 are arranged inside the cavity at its opening position. The rubber rings 448 divide the cavity at the lower end of the adsorption head 444 into a plurality of separate adsorption cavities 449. Each group of adsorption cavities 449 is connected to the gas delivery hose 445 through a separate gas delivery groove 450.

[0034] By providing the rubber ring 448, each adsorption chamber 449 can work independently, so the equipment is more flexible in processing multiple items of different sizes and shapes and can cope with more complex operation requirements. The rubber ring 448 can effectively seal each adsorption chamber 449, reduce gas leakage during the adsorption process, and improve adsorption efficiency and stability.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
