Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a suction device for a shipping robotic arm. Background Technology

[0002] In modern industry, robotic arms are increasingly used for the handling, movement, and transfer of materials in small areas. The grippers of robotic arms are divided into clamp grippers and suction cup grippers. Clamp grippers are more expensive and more complicated to operate, while suction cup grippers are cheaper and easier to operate.

[0003] The principle behind suction cups is to create a vacuum between the suction cup and the object, thus forming negative pressure to pick up the object. When there is dust on the surface being picked up, a gap will be created between the suction cup and the object, affecting the vacuum effect. During the process of the suction cup picking up the object and moving it, the suction may be insufficient due to air entering the suction cup, causing the object to fall off. Moreover, as the suction cup is used for a long time, dust from the object and the environment will also adhere to the surface of the suction cup, and over time, the suction cup's ability to pick up objects will decrease. Utility Model Content

[0004] The purpose of this utility model is to provide a suction device for a shipping robot in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A suction device for a shipping robot includes an adjusting rod, a mounting plate at the bottom of the adjusting rod, and a suction cup for holding goods mounted on the bottom surface of the mounting plate. The bottom surface of the suction cup is provided with two protective plates that are mirror-symmetrical. The two protective plates have a scraping port at one end opposite to each other and a clearance bevel at the other end opposite to each other.

[0007] As a further description of the above technical solution:

[0008] The mounting plate is fixedly fitted with a mounting ring. Two L-shaped plates are movably mounted on the bottom of the mounting ring in a mirror-symmetric manner. Two electric push rods are hinged to each L-shaped plate. Mounting blocks are provided on the top surfaces of the opposite ends of the two protective plates. The telescopic ends of the electric push rods are hinged to the corresponding mounting blocks.

[0009] As a further description of the above technical solution:

[0010] The mounting ring has mirror-symmetrical mounting holes, and a T-shaped guide rod is vertically slidably installed in each mounting hole and fixed to the top surface of the L-shaped plate. A return spring is sleeved on the rod between the mounting ring and the L-shaped plate.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] In this invention, two protective plates that can be opened and closed are used to prevent dust from entering the suction cup's adsorption surface. At the same time, the dust scraping openings on the protective plates can push the dust on the surface of the item to be adsorbed to one side. The overall movable and upward-moving protective plates can ensure that the suction cup is completely attached to the surface of the item and will not affect the suction cup's gripping function.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1:

[0019] like Figure 1-3 As shown, a suction device for a shipping robot includes an adjusting rod 1, a mounting plate 2 at the bottom of the adjusting rod 1, and a suction cup 3 for holding goods mounted on the bottom surface of the mounting plate 2. The working principle and movement method of the suction cup 3 are existing technologies and will not be described in detail here. Two protective plates 4 are mirror-symmetrically arranged on the bottom surface of the suction cup 3. The two protective plates 4 have a dust scraping port 10 at one end opposite to each other and a clearance bevel 9 at the other end. The two protective plates 4, which can be opened and closed, can be used to prevent dust from adsorbing the suction surface of the suction cup 3. At the same time, the dust scraping port 10 on the protective plate 4 can push the dust on the surface of the item to be adsorbed to one side. The movable and upward-moving protective plates 4 can ensure that the suction cup 3 is completely attached to the surface of the item and will not affect the gripping function of the suction cup 3.

[0020] Example 2:

[0021] The technical solution is basically the same as that in Embodiment 1, except that, as Figure 1-3As shown, a mounting ring 7 is fixedly fitted around the mounting plate 2. Two L-shaped plates 5 are movably mounted on the bottom of the mounting ring 7 in a mirror-symmetrical manner. Two electric push rods 6 are hinged to each L-shaped plate 5. Mounting blocks are provided on the top surfaces of the opposite ends of the two protective plates 4. The telescopic ends of the electric push rods 6 are hinged to the corresponding mounting blocks. The electric push rods 6 can be used to open and close the protective plates 4, thereby opening and protecting the suction cup 3. Mounting holes are symmetrically opened on the mounting ring 7. T-shaped guide rods 8 are vertically slidably mounted in each mounting hole and fixed to the top surface of the L-shaped plates 5. A return spring is fitted on the rod body of the guide rod 8 located between the mounting ring 7 and the L-shaped plates 5. The guide rods 8 facilitate the movement of the entire protective plate 4 and the electric push rods 6 when the suction cup 3 moves down to adsorb the item.

[0022] Working principle: In use, the external control mechanism moves the suction cup 3 equipped with protective plates 4 downwards, so that the protective plates 4 are attached to the surface of the item to be adsorbed. Then, the electric push rod 6 is extended, opening the two protective plates 4 and exposing the suction cup 3. As the protective plates 4 move along the surface of the item to be adsorbed, the scraper nozzle 10 pushes the dust in the area to be adsorbed outwards, making the area adsorbed by the suction cup 3 clean. After the protective plates 4 are fully open, the external control mechanism continues to control the suction cup 3 to move downwards, so that the suction cup 3 is attached to the surface of the item that has been scraped clean by the protective plates 4. Then, a vacuum is drawn to form a negative pressure to adsorb the item. At this time, the entire protective plate 4 and the electric push rod 6 move upwards, and the return spring is compressed. When the suction cup 3 is not in use, the electric push rod 6 is retracted, and the protective plates 4 are covered again on the working surface of the suction cup 3. The clearance bevel 9 on the protective plate 4 ensures that the protective plate 4 will not be blocked by the suction cup 3 and damage the suction cup 3.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
