[0002] The demand for vacuum technology is increasing in the collaborative robot field, with numerous material handling applications. This is particularly true in the logistics industry, where customers often need to use the same suction cups to move different types of cardboard boxes.

[0003] Collaborative robots have limited payload capacity. In order to move the heaviest possible workpieces, there are high restrictions on the weight of the accompanying suction device, requiring a lightweight suction device.

[0004] Taking cardboard boxes as an example, the vacuum cleaner needs to be compatible with different workpieces to be suitable for gripping most cardboard boxes in the logistics industry. However, cardboard boxes are permeable and prone to deformation during handling. Currently, most end-point vacuum cleaners on the market have low flow rates, poor compatibility with different cardboard boxes, and lack features such as component drop detection and vacuum level detection. To address these issues, a lightweight vacuum cleaner needs to be developed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a lightweight suction cup that is compatible with workpieces of different sizes.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a lightweight suction device, comprising a cavity, a valve core, a suction cup, a cover plate and a sealing ball, wherein a diversion block and a positioning block are fixedly disposed in the cavity; The cover plate is sealed and fixedly installed on the top of the cavity, forming a negative pressure area between the cover plate and the cavity. The positioning block is provided with a first air passage that is the same as the outside. The diversion block is provided with a diversion air passage. The left and right ends of the valve core are fixedly installed on the positioning block and the diversion block, respectively. The two ends of the valve core are connected to the first air passage and the diversion air passage, respectively. An air pipe connector is fixedly installed on the diversion block. The air pipe connector is sealed and fixedly installed with the cover plate. The cavity has airflow holes arranged in a linear array that communicate with the negative pressure area. The suction cups are connected to the airflow holes one by one and are sealed and fixedly installed on the bottom surface of the cavity. The airflow hole is designed as a coaxial stepped hole with a smaller upper part and a larger lower part. The sealing ball is placed in the larger lower part of the airflow hole, and the sealing ball can block the smaller upper part of the airflow hole.

[0007] Furthermore, the suction cup is sealed and fixedly installed on the carrier plate, and a support plate is sealed and fixedly installed on the top of the carrier plate. The support plate is provided with staggered holes corresponding to the airflow holes. The sealing ball is placed in the staggered holes, and the combination of the carrier plate and the support plate is sealed and fixedly installed on the bottom surface of the cavity.

[0008] Furthermore, a first sealing ring groove is provided at the edge of the cavity, and a first sealing ring is embedded in the first sealing ring groove, with the cover plate pressing on the first sealing ring.

[0009] Furthermore, a reinforcing column is integrally formed at the bottom of the cavity groove, a second sealing ring groove is provided at the top of the reinforcing column, and a third sealing ring groove is provided at the top of the diverter block. The third sealing ring groove is coaxially arranged with the air pipe connector. The second sealing ring and the third sealing ring are respectively embedded in the second sealing ring groove and the third sealing ring groove. The cover plate is bolted to the cavity and the reinforcing column, and the cover plate is pressed on the first sealing ring.

[0010] Furthermore, the bottom of the cavity is integrally formed with reinforcing ribs.

[0011] Furthermore, a photoelectric switch is sealed and fixedly installed on the cavity, and the photoelectric switch is also sealed and fixedly connected to the cover plate.

[0012] Furthermore, a monitoring connector communicating with the negative pressure area is also sealed and fixedly installed on the cover plate, and a negative pressure gauge is installed on the monitoring connector.

[0013] Compared with existing technologies, the advantages of this invention are: the cavity is made of PA6+GF30 reinforced glass fiber, and the suction cup has an external size of 314x224mm, resulting in a lightweight suction device weighing only about 3 kg. This allows for easy integration with lightweight robots, significantly improving process efficiency while effectively reducing production costs. Its optimized suction cup grid design greatly reduces the power required to generate a vacuum, achieving efficient energy utilization. The sealing ball corresponding to the unused suction cup is lifted to seal the small holes at the top of the airflow orifice, enabling seamless integration into palletizing solutions. This provides great flexibility and scalability, adapting flexibly to various workpiece positions and shapes, ensuring superior performance in different application scenarios.
