Description

Technical Field

[0001] This utility model relates to the field of vacuum suction cup technology, specifically a vacuum suction cup that facilitates rapid material suction. Background Technology

[0002] A vacuum suction cup is an industrial device that uses the principle of air pressure difference to grasp and transport objects. It is widely used in automated production lines and logistics. A search revealed that patent CN209273275U discloses a rapid adsorption vacuum suction cup, including a suction cup mounting box and an internal vacuum suction cup. An electric push rod is located at the bottom of the vacuum suction cup. The vacuum suction cup moves up and down along guide wheels inside the suction cup mounting box as the electric push rod extends and retracts, facilitating faster separation between the vacuum suction cup and the workpiece. A movable steel wire rope is also provided on the inner wall of the suction cup mounting box, always positioned above the vacuum suction cup. When a workpiece is being processed, the steel wire rope is located in the gap between the suction cups, providing support for the workpiece when the vacuum suction cup separates from it. However, in actual production, some workpieces do not require through-processing, while others only require processing of their bottom or top. Therefore, it is inconvenient to process the bottom of the workpiece while it is being held in place. To address this, a vacuum suction cup is designed that facilitates V-shaped workpiece holding and allows for easy adjustment of the V-angle, enabling simultaneous processing of the top and bottom of the workpiece while holding it in place. This design is suitable for holding workpieces of different specifications and allows for rapid material handling. Utility Model Content

Detailed Implementation

[0013] 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. Example:

[0014] Please see Figure 1-4 A vacuum suction cup for quick material suction includes a fixed frame 1. Two rotating bars 2 are rotatably connected to the fixed frame 1. The bottom of each of the two rotating bars 2 is provided with multiple vacuum tubes 3 with downward-facing and flat bottom vacuum suction ports 4. The bottom surfaces of the multiple rotating bars 2 on the two rotating bars 2 are flush. The fixed frame 1 is provided with a tension adjustment mechanism for driving the two rotating bars 2 to open and close. The fixed frame 1 is also provided with a pressure difference adjustment mechanism that communicates with the two vacuum tubes 3.

[0015] Specifically, the tensioning and adjusting mechanism includes a drive bevel gear 13 and two transmission bevel gears 14. The two transmission bevel gears 14 are symmetrically rotatably connected to the fixed frame 1, and the two rotating bars 2 are fixedly connected to the two transmission bevel gears 14 respectively. The drive bevel gear 13 is rotatably connected to the fixed frame 1 and meshes with the two transmission bevel gears 14 simultaneously. It also includes a drive component that drives the drive bevel gear 13 to rotate in both directions.

[0016] Furthermore, the driving component includes an adjusting motor 15 fixedly mounted on the fixed frame 1. The adjusting motor 15 has an output shaft that can be stopped and locked immediately, and will not rotate during operation, thereby improving the stability of the included angle of the two rotating bars 2. When the driving component is started, the output shaft of the driving component rotates clockwise or counterclockwise, thereby driving the active bevel gear 13 to rotate clockwise or counterclockwise, thereby driving the two transmission bevel gears 14 to rotate relative to each other towards the middle or towards both sides, thereby driving the two rotating bars 2 to cooperate towards the middle and rotate towards both sides, thereby making the included angle of the V-shaped structure smaller or larger.

[0017] Specifically, the differential pressure regulating mechanism includes a gas tank 8 fixedly installed on the top of the fixed frame 1. A pressure plug 9 is sealed and slidably fitted inside the gas tank 8. Two annular grooves are opened on the bottom outer side of the gas tank 8, and multiple vent holes 10 are opened through the two annular grooves. A rotating sealing ring 11 is fixedly connected to the annular grooves through a vacuum connecting pipe 6 and a vacuum tube 3. The top of the gas tank 8 is vented to the outside, and a pull-out assembly for pulling up the pressure plug 9 is provided on the top of the gas tank 8.

[0018] When adjusting the air pressure difference, the air pressure plug 9 is pulled upwards using the pull-out assembly, which lifts the air at the bottom of the air pressure plug 9 in the air tank 8. This, in turn, creates suction at multiple vacuum tubes 3 through the rotating sealing ring 11, vacuum connecting pipe 6, and vacuum tube 3, thus securing the workpiece. When the air pressure plug 9 is pressed down using the pull-out assembly, the air at the bottom of the air pressure plug 9 in the air tank 8 is pushed down and discharged through the vacuum connecting pipe 6, vacuum tube 3, and multiple vacuum tubes 3, thereby securing the workpiece. Furthermore, the vacuum connecting pipe 6 is sealed and connected to the vacuum tube 3 at the end of the rotating strip 2 away from the fixed frame 1, improving the ease of rotation of the V-shaped structure and enhancing the overall structural stability. Additionally, both the vacuum connecting pipe 6 and the vacuum tube 3 are equipped with clamps 7 that are fixedly connected to the rotating strip 2, further enhancing the overall structural stability of the vacuum tube 3 and the vacuum connecting pipe 6, and further improving the stability of the workpiece's suction.

[0019] Specifically, the pull-out assembly includes a drive cylinder 12 fixedly installed on the top of the gas tank 8. The bottom output shaft of the drive cylinder 12 is fixedly connected to the top of the air pressure plug 9, and the gas tank 8 is provided with a ventilation structure at the connection point of the drive cylinder 12.

[0020] The ventilation structure can be configured as a ventilation slot through which the output shaft of the drive cylinder 12 can pass, or a separate ventilation hole 10 can be opened. The air pressure plug 9 can be easily adjusted by the drive cylinder 12. Furthermore, the drive cylinder 12 is preferably hydraulically driven.

[0021] Specifically, an elastic rubber ring 5 with its bottom protruding from the bottom of the vacuum suction port 4 is provided at the bottom opening of the vacuum suction port 4.

[0022] The elastic rubber ring 5 helps to reduce collisions with the workpiece during suction, avoids scratches on the workpiece, and improves the stability of suction.

[0023] Specifically, a mounting bracket 16 is fixedly installed on the fixed frame 1, which facilitates the installation of the vacuum suction cup that can quickly pick up materials.

[0024] In use, the device is installed at the front end of the workpiece gripping equipment via the mounting bracket 16. According to the specifications of the workpiece and the position to be processed, the angle of the two rotating bars 2 is adjusted by the opening and closing adjustment mechanism so that the multiple vacuum suction ports 4 on the two rotating bars 2 can completely cover the workpiece and completely avoid the position to be processed. Then, the multiple vacuum suction ports 4 are pressed on the workpiece, and then the air pressure adjustment mechanism forms a negative pressure at the vacuum suction ports 4 to fix the workpiece. After gripping, the workpiece can be processed from the top and bottom.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
