Description

Technical Field

[0001] The utility model relates to a flexible multi-standard material handling suction cup. Background Art

[0002] Existing vacuum suction cups suck and carry products by generating negative pressure (lower than atmospheric pressure) gas through a vacuum generator or vacuum pump. The vacuum suction cup completes product transportation under the triggering of negative pressure gas, but the surface of the transported product must be flat and smooth without foreign matter. After suction, the surface of the product or the surface of the bagged product should not be wrinkled or leaked in the opposite direction. For products with irregular shapes, wrinkles and bulging (such as bagged skin care products, bagged foods) and products with large surface bumps (such as multi-curved bottled products, sugar apples, dragon fruits, etc.), vacuum suction cups in the prior art generally use soft lip suction cups or conventional sponge suction cups for suction and transportation. Soft lip suction cups use negative pressure to attach the rubber lip to the product, and form an adsorption force under the action of negative pressure, thereby realizing the product transportation and transfer function. Sponge suction cups are attached to the product through negative pressure, and form an adsorption force under the action of negative pressure, thereby realizing the product transportation and transfer function. However, due to the uneven surface of the product, in order to achieve the required vacuum degree, it is necessary to increase the negative pressure to improve the adsorption force. The suction surface will be damaged during the suction and transportation process, and the end execution or mechanism transportation speed is slow.

[0003] For example, the adsorption sponge layer of the sponge suction cup in the prior art is relatively thin. When adsorbing products, the sponge compression distance is short and it has no buffering function, which causes the inner lip of the sponge to be easily torn. The service life of the prior art is: the number of handling times ≤ 100,000 times; the high-speed manipulator drives the end effector to handle at a speed of 3,600-4,800 times / hour; which further leads to the low service life and high cost of use of the sponge suction cup in the prior art; due to the material factor of the sponge itself, the attachment sealing effect is lower than that of the rubber lip suction cup. The prior art increases the negative pressure to increase the adsorption force. Under high negative pressure conditions, the adsorbed product is easily damaged, thereby affecting the product quality, further resulting in the inability of traditional sponge suction cups to be used for high-frequency handling of bagged skin care products, bagged foods, sugar apples, dragon fruits and other products with special requirements. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a flexible multi-specification material handling suction cup, which can complete the suction and handling of special-shaped, wrinkled and bulging products (such as bagged skin care products, bagged foods) and products with large surface bumps (such as multi-curved bottled products, sugar apples, pitaya, etc.), and because the force structure and handling method are optimized, the vacuum negative pressure value can be reduced, thereby protecting the suction surface of the product from damage during the suction and handling process, and improving the terminal execution or mechanism handling speed.

[0005] The technical solution to achieve the above purpose is: a flexible multi-standard material handling suction cup, including a sponge lip, a sponge lip adhesive plate, a suction cup mounting frame and a threaded sealing joint, wherein:

[0006] The sponge lip is in a circular ring shape, and the overall thickness of the sponge lip is 30 to 50 mm;

[0007] The sponge lip adhesive plate is a breathable mesh plate;

[0008] The suction cup mounting frame is a cylindrical structure with a hollow interior;

[0009] The top end of the sponge lip is glued to the bottom end of the sponge lip adhesive plate by glue, the sponge lip adhesive plate is clamped to the bottom end of the suction cup mounting frame, and the threaded sealing joint is clamped to the top end of the suction cup mounting frame.

[0010] The above-mentioned flexible multi-standard material handling suction cup, wherein the suction cup mounting frame is made of rubber material.

[0011] The above-mentioned flexible multi-standard material handling suction cup, wherein the threaded sealing joint is externally connected to a vacuum generating device.

[0012] The flexible multi-standard material handling suction cup of the utility model has the following advantages:

[0013] (1) The sponge lip can form a covering effect from the inside to the outside. During the product adsorption and transportation process, the suction cup of the utility model is less affected by the inertia of the product that is accelerated or decelerated during the transportation process than the prior art. This feature can directly affect the transportation speed of the suction cup (for the same transportation stroke of 400 mm and the same items, the reciprocating transportation speed of the prior art without dropping during the transportation process is 60 times / min, while the experimental result of the utility model without dropping during the transportation process is more than 120 times / min). In addition, since the covering effect formed by the sponge lip is more stable, it can grab and carry products such as easily broken packaging bags, sugar apples, dragon fruits, etc. by reducing the negative pressure, filling the gap in the industry;

[0014] (2) The utility model improves the stress structure of the sponge lip layer, reduces the pulling force of the inner lip, and thus increases the service life of the suction cup (experimental tests show that the number of times the prior art can be used is 50,000 to 100,000 times, while the number of times the utility model can be used is 2 to 3 million times). The breathable mesh structure design of the sponge lip adhesive plate and the optimization of the stress structure of the sponge layer enable the suction cup of the utility model to transport products that the prior art cannot transport, such as agricultural products that cannot withstand large negative pressure, easily broken packaging bags, and easily broken material product surfaces. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 for Figure 1 AA section view. DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the utility model, the specific implementation method thereof is described in detail below in conjunction with the accompanying drawings:

[0018] See also Figure 1 and Figure 2 The best embodiment of the utility model is a flexible multi-standard material handling suction cup, including a sponge lip 3, a sponge lip adhesive plate 2, a suction cup mounting frame 1 and a threaded sealing joint 4.

[0019] The sponge lip 3 is in a circular ring shape, and the overall thickness h of the sponge lip 3 is 30-50 mm; the sponge lip pasting plate 2 is a breathable mesh plate; the suction cup mounting frame 1 is a hollow cylindrical structure; the top of the sponge lip 3 is pasted to the bottom of the sponge lip pasting plate 2 by glue, the sponge lip pasting plate 2 is clamped to the bottom of the suction cup mounting frame 1, and the threaded sealing joint 4 is clamped to the top of the suction cup mounting frame 1. The suction cup mounting frame 1 is made of rubber material.

[0020] The flexible multi-standard material handling suction cup of the utility model has a threaded sealing joint 4 externally connected to a vacuum generating device, and the vacuum is guided to the threaded sealing joint 4 through air path devices such as air pipes and joints, so that the inner cavity of the suction cup mounting frame 1 and the inner cavity of the sponge lip 2 form a negative pressure. When in use, it is installed under the drive of the end effector or other driving structure to contact the product to be transported. After the inner lip 31 of the sponge lip 3 contacts the product, the inner lip 31 shrinks under the action of negative pressure, and the sponge contact surface gradually increases toward the outer lip 32 to form a covering effect from the inside to the outside. If the product has a curved surface or a concave-convex surface, the shrinkage property of the sponge will cover or fill it to ensure the vacuum degree of the inner cavity of the suction cup mounting frame 1 and the inner cavity of the sponge lip 2, and ensure that the transported product does not fall due to inertia during high-speed transportation, thereby increasing the transportation speed; compared with the prior art, the sponge lip is thickened, and the thickness h of the sponge lip reaches 30 to 50 mm. , 20-30mm higher than the sponge layer in the prior art, the wall thickness w of the sponge lip 3 (the distance between the inner lip 31 and the outer lip 32) reaches 40-60mm, which is 20-30mm larger than the sponge layer in the prior art. The sponge lip pasting plate 2 adopts a breathable mesh plate, which can increase the compression buffer of the sponge lip 3 after contacting the product. During the compression process of the sponge lip 3, the pulling force of the inner lip 31 can be reduced, and the transported product compresses the sponge to a certain extent under the action of negative pressure. The product will contact the mesh plate to ensure the overall suction effect while offsetting a part of the adsorption pulling force, thereby protecting the product surface from being damaged by negative pressure factors. Product packaging bags or product surfaces.

[0021] To sum up, in the flexible multi-standard material handling suction cup of the utility model, the sponge lip contacts with the product, and during the contact process, since the internal air pressure of the suction cup is lower than the ambient air pressure, the thickened sponge lip shrinks and adheres according to the surface shape of the product, and after the attached product is affected by the negative pressure, the product compresses the sponge lip and the sponge lip can simultaneously cover the product, thereby achieving buffered contact, reducing the tearing force of the sponge lip, and extending the service life of the sponge lip of the suction cup; and even when the transported product contacts with the breathable mesh plate under the action of negative pressure, a part of the adsorption pulling force can be offset while ensuring the overall adsorption effect, thereby protecting the product surface from being damaged by the negative pressure factor and damaging the product packaging bag or the product surface, thereby achieving product handling.
