Description

Technical Field

[0001] The utility model relates to the technical field of glass product transportation, in particular to a device for preventing misoperation and collision of a manipulator suction cup frame. Background Art

[0002] The production of float glass involves melting, forming, annealing, optimized cutting, palletizing, and packaging. Optimized cutting involves minimizing the size of defective or substandard glass sheets after automated inspection and grading. The resulting glass sheets must meet national standard dimensions. The cut glass is then palletized and packaged according to different specifications and grades. Currently, the automation level of float glass production in my country is rapidly developing. The most direct solution for increasing automation in high-volume production is the use of palletizing robots. The palletizing robot's manipulator primarily uses a suction cup to pick up glass. While this process is highly efficient, it also poses safety risks, particularly in the event of operator error. For example, if a worker operates the rotating platform while a shelf is already filled with glass, then activates the manipulator, assuming there is no glass. The manipulator then picks up the first piece of glass in the shelf. This can cause the entire suction cup to collide with the existing glass, breaking it and causing economic losses and safety incidents. Therefore, a safe and reliable anti-collision device for the manipulator's suction cup is urgently needed. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a device for preventing misoperation and collision of a robot suction cup frame to avoid glass being damaged by collision, causing economic losses and safety accidents, improve safety performance and reduce production costs.

[0004] The purpose of this utility model is achieved in this way:

[0005] A device for preventing accidental operation and collision of a manipulator suction cup frame is provided on the suction cup frame and includes a proximity switch, a proximity switch bracket, a fixed sleeve, a sliding shaft, a spring, and a nylon sleeve. The side of the fixed sleeve is fixed to the suction cup frame, and the center of the fixed sleeve is provided with a center hole for passing the sliding shaft. The sliding shaft is slidably provided in the center hole of the fixed sleeve, and a flat portion is provided on the top end of the sliding shaft. The diameter of the flat portion is larger than the diameter of the sliding shaft. When the sliding shaft passes through the fixed sleeve, the flat portion is provided above the fixed sleeve.

[0006] The bottom of the sliding shaft is covered with a protective sleeve to provide protection and buffering during collisions; the sliding shaft is also covered with a spring, which is arranged between the fixed sleeve and the protective sleeve;

[0007] A proximity switch is provided on one side of the flat portion of the sliding shaft. The proximity switch is arranged on a proximity switch bracket. The end of the proximity switch passes through the proximity switch bracket and reaches above the flat portion of the sliding shaft. When the sliding shaft moves upward, it touches the proximity switch.

[0008] Furthermore, the suction cup rack includes multiple vertical brackets arranged in parallel, two horizontal brackets are set on the brackets for connection, multiple evenly distributed suction cup units are set on the side of each vertical bracket, and a fixing sleeve is set on the outer side of the outermost vertical bracket.

[0009] Furthermore, the proximity switch bracket is an L-shaped plate, which is arranged on one side of the flat portion of the sliding shaft, and its bottom surface is fixed to the upper surface of the vertical bracket connected to the fixed sleeve.

[0010] Furthermore, a through hole is provided on the side of the proximity switch bracket for installing the proximity switch, and the end of the proximity switch passes through the through hole of the proximity switch bracket and reaches above the flat portion of the sliding shaft.

[0011] Furthermore, a nylon sleeve is provided on the bottom of the sliding shaft to provide protection and buffering during collision.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This utility model provides a device to prevent accidental operation and collision of a manipulator suction cup frame. The manipulator arm drives the suction cup frame to grab cut glass from the production line and place it on the glass rack. When the suction cup frame is operating normally, the device is not triggered. However, if an accident occurs, such as the suction cup frame colliding with other nearby objects or the nylon sleeve touching the obstacle, the manipulator arm is immediately triggered to pause, preventing the glass from being broken. This utility model reduces the uncertainty of manual operation, reduces economic losses, avoids safety accidents, and improves the efficiency and safety of glass production.

When an accident occurs, the suction cup frame 7 collides with other nearby objects, such as a glass conveyor roller, a guardrail, a glass frame, etc., and the nylon sleeve 6 touches the obstacle, driving the sliding shaft 4 to move axially. The spring 5 is compressed, and the flat part of the sliding shaft 4 triggers the proximity switch 1, which feeds back the signal to the system control unit, executes the manipulator to pause and triggers the alarm device; after the maintenance personnel resolve the above-mentioned collision accident on site, the spring 5 is reset, the sliding shaft 4 returns to its original position, and the signal of the proximity switch 1 returns to normal.

[0036] When different specifications of glass need to be sucked, the cylinder 8.1 and the suction cup 8.7 are driven in groups according to the set program. After the corresponding glass is sucked, it is stacked on the glass rack. The cylinder 8.1 moves according to the process requirements, driving the cylinder connecting sleeve 8.2, the shift fork 8.3, the movable shaft 8.5, and the suction cup 8.7 to make up and down reciprocating movements on the mounting seat 8.4. The suction cup spring 8.6 acts as a buffer during the above movement.
