Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a suction cup mechanism, including a first suction cup panel 1 and a second suction cup panel 2. The first suction cup panel 1 and the second suction cup panel 2 are two separate suction cup panels, and each of the first suction cup panel 1 and the second suction cup panel 2 has a plurality of suction cups inside. The adsorption surfaces of the first suction cup panel 1 and the second suction cup panel 2 have a plurality of air extraction holes that communicate with the outside and can generate adsorption force to adsorb products. A driving component 3 is provided between the first suction cup panel 1 and the second suction cup panel 2, which can drive the second suction cup panel 2 to separate from the first suction cup panel 1, thereby expanding the adsorption area. The driving component 3 includes a stepper motor 30 connected to the back of the first suction cup panel 1, and a plurality of mounting plates 31 that are drivenly connected to the stepper motor 30. The other end of the mounting plate 31 is fixedly connected to the second suction cup panel 2. The driving component 3 also includes one end that is drivenly connected to the stepper motor 30. The coupling 32 has a transmission screw 33 at one end. The drive assembly 3 also includes a connecting plate 35 connected to all mounting plates 31. The connecting plate 35 has a connecting seat 36 fixedly connected to it. The connecting seat 36 is connected to the transmission screw 33. By driving the coupling 32 to rotate by the stepper motor 30, the transmission screw 33 is rotated, which causes the connecting seat 36 to move along the transmission screw 33. Since the connecting seat 36 is connected to the connecting plate 35, and the connecting plate 35 is connected to all mounting plates 31, and the other end of the mounting plate 31 is connected to the second suction cup panel 2, the movement of the connecting seat 36 along the transmission screw 33 can simultaneously drive the second suction cup panel 2 to move. This adjusts the adsorption area between the first suction cup panel 1 and the second suction cup panel 2, thereby adapting to the adsorption of products of different sizes and ensuring the stability of product adsorption.

[0021] To ensure the transmission stability of the lead screw 33, the first suction cup panel 1 is also provided with two lead screw seats 34, wherein the lead screw 33 and the lead screw seats 34 are rotatably engaged, and the lead screw seats 34 are provided at both ends of the lead screw 33.

[0022] Mounting plate 31 is also provided with a sensing plate 4 fixedly connected thereto. On the first suction cup panel 1, a limit sensor 5 is provided corresponding to the sensing plate 4. There are two limit sensors 5 in the moving direction of the sensing plate 4. If the sensing plate 4 contacts the limit sensor 5 near the middle of the first suction cup panel 1, it means that the second suction cup panel 2 is in the initial position and has not moved. When the stepper motor 30 drives the second suction cup panel 2 to move, when the sensing plate 4 contacts the limit sensor 5 near the edge of the first suction cup panel 1, it means that the second suction cup panel 2 has reached the maximum moving distance. At this time, the limit sensor 5 sends a signal to the stepper motor 30 to control the stepper motor 30 to stop driving.

[0023] A suction sensor 6 is also provided on the first suction cup panel 1. The first suction cup panel 1 is provided with a through hole 7 corresponding to the suction sensor 6. When the product is being suctioned and transferred, the suction sensor 6 can sense whether the product has been suctioned or has been discharged through the through hole 7.

[0024] The first suction cup panel 1 and the second suction cup panel 2 are each provided with several air pipe connectors 8, wherein the air pipe connectors 8 are connected to the suction cup to provide negative pressure.

[0025] The working principle of this utility model is as follows: By using a stepper motor 30 to drive the transmission screw 33 to rotate, the connecting seat 36 moves along the transmission screw 33. When the connecting seat 36 moves, it is equivalent to driving the connecting plate 35 to move synchronously. Since the connecting plate 35 is connected to the mounting plate 31, and the mounting plate 31 is connected to the second suction cup panel 2, it is equivalent to driving the second suction cup panel 2 to move, thereby changing the distance between the first suction cup panel 1 and the second suction cup panel 2. In this way, when dealing with products with large areas, it is equivalent to changing the adsorption position of the first suction cup panel 1 and the second suction cup panel 2 on the product, thereby ensuring stable adsorption of products with large areas. Therefore, by using the stepper motor 30 to drive the second suction cup panel 2 to separate from the first suction cup panel 1, it is equivalent to adjusting the adsorption area that can be covered between the first suction cup panel 1 and the second suction cup panel 2, thereby adapting to the adsorption of products of various sizes, and ensuring that products can be stably loaded and unloaded.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
