The purpose of designing this type of mechanism is to improve production efficiency, reduce labor costs and ensure the accuracy and safety of operations. According to different application requirements and product characteristics, product packaging gripping mechanisms can have various types and designs. Common ones include robotic arms with suction cups, claw grippers, soft clamping systems, magnetic grippers, etc. Among them, robotic arms with suction cups are suitable for grabbing packaging boxes or bags on flat and smooth surfaces. The products are adsorbed by vacuum suction, and the robotic arms are responsible for movement and positioning.

[0003] The existing suction cups mainly absorb products with relatively flat surfaces and relatively hard product materials. For products with soft film packaging, the gripping is not firm, or the surface of the product packaging film is wrinkled and broken, resulting in uneven product gripping and damage to the outer surface of the product packaging film. After grabbing the product, the product shakes greatly during operation, and the product is easy to fall off the vacuum suction cup, resulting in poor stability during operation.

[0023] Embodiment 1:

[0024] like Figure 1 As shown, a film sponge suction cup for a product packaging grasping mechanism includes a fixed plate 1, a support plate 2 and a sealing ring 3. The fixed plate 1 is connected to the support plate 2, and the fixed plate 1 is also connected to the sealing ring 3. A vacuum tube 11 and a vacuum chamber 12 are provided on the fixed plate 1. The vacuum tube 11 is connected to the vacuum chamber 12. The vacuum tube 11 is used to connect an external vacuum source and the vacuum chamber 12. The vacuum chamber 12 is used to vacuum absorb the product. The support plate 2 is used to fix the film surface on the product and deform it. The sealing ring 3 is used to deform during vacuum absorption to increase the stability of the product. Through the structural coordination of the fixed plate 1, the support plate 2 and the sealing ring 3, the stability of the soft film outer packaging product is improved in a targeted manner, and the outer surface of the product packaging film is avoided from being damaged. The shaking amplitude is relatively small when running after grabbing the product, and the overall operation is relatively stable.

[0025] Embodiment 2:

[0026] like Figure 2 , 3As shown, a film sponge suction cup for a product packaging grasping mechanism includes a fixing plate 1, a supporting plate 2 and a sealing ring 3. The fixing plate 1 is connected to the supporting plate 2, and the fixing plate 1 is also connected to the sealing ring 3. A vacuum tube 11 and a vacuum cavity 12 are provided on the fixing plate 1. The vacuum tube 11 is connected to the vacuum cavity 12. The vacuum tube 11 is used to connect an external vacuum source and the vacuum cavity 12. The vacuum cavity 12 is used for vacuum adsorption of products. The supporting plate 2 is used to fix and deform the film surface on the product. The sealing ring 3 is used to deform during vacuum adsorption to increase product stability.

[0027] The fixing plate 1 and the supporting plate 2 are both made of aluminum plates, and the diameter of the fixing plate 1 is 115 mm, the diameter of the supporting plate 2 is 52 mm, the inner diameter of the sealing ring 3 is 80 mm, the outer diameter of the sealing ring 3 is 115 mm, and the outer diameter of the product adsorption surface is 105 mm.

[0028] A vacuum adsorption chamber 13 is also provided on the fixing plate 1 , and the vacuum adsorption chamber 13 is connected with the vacuum tube 11 and the vacuum chamber 12 .

[0029] The fixing plate 1 and the supporting plate 2 are provided with threaded holes 121 which are adapted to each other. Bolts for connecting and fixing the fixing plate 1 and the supporting plate 2 are connected in the threaded holes 121. In order to increase the contact area between the product packaging film and the supporting plate 2, the larger the contact area, the larger the force area, and the product adsorption surface. The film is not easy to deform or break during adsorption.

[0030] The sealing ring 3 is made of sponge. The bottom of the sponge is composed of countless small holes. Each small hole is like a suction cup. It can automatically sense whether an object is in contact. The holes that are not in contact will automatically close, which can achieve a good sealing performance. The deformed sponge in a vacuum state has no gas molecules. The pressure of the gas molecules in the sponge is reduced, resulting in a smaller volume of the sponge, and a deformed shape and hardening. The outer diameter of the sponge is 115mm, which is larger than the diameter of the adsorption surface of the product, which is 105mm. The characteristics of the sponge and the shape of the product are used to form an outer wrapped cavity C in a vacuum state (refer to Figure 4 ), which will better wrap the product, form a good sealing ring to isolate the external air, and increase the stability of the product and the suction cup.

[0031] The sealing ring 3 is provided with an adhesive layer 31 for bonding and fixing, and the sealing ring 3 is connected to the fixing plate 1 via the adhesive layer 31 .

[0032] Working principle of the utility model: During the process of grabbing products, the sponge vacuum suction cup uses the sealing ring 3 made of sponge material as a sealing member, which is fixed to the fixed plate 1 through the adhesive layer 31. The vacuum tube 11, the vacuum adsorption chamber 13 and the vacuum chamber 12 are interconnected. The fixed plate 1 is connected to the support plate 2 by bolts. The lower surface of the support plate 2 fits with the film B of the product A (such as the film at the bottom of the instant noodle box). Under the vacuum state, the support plate 2 serves as a surface for fixing the supporting film. When the sealing ring 3 (sponge) deforms and absorbs the product under the vacuum state, a convex cavity is formed to make the product more stable, and prevent the film from deforming and shaking during the adsorption process. The concave taper formed by the outer film of the product and the suction cup cavity can better stabilize the product on the suction cup. During the process of adsorbing the product, the convex cavity of the suction cup and the concave cavity of the product film form a good bonding surface. An outer wrapping cavity C is formed between the sealing ring 3 and the product under the vacuum state (refer to Figure 4 ), thus preventing the product from sliding or falling off during the grabbing and running process.

[0033] It should be noted that the preferred implementation methods of the utility model are given in the specification and drawings of the utility model. However, the utility model can be implemented in many different forms and is not limited to the implementation methods described in the specification.

In addition, the above-mentioned technical features continue to be combined with each other to form various implementation methods not listed above, which are all regarded as the scope of the description of the utility model; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the scope of protection of the claims attached to the utility model.
