Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4 shown, it includes a cargo tray 1, a horizontal bracket 2, a glass suction mechanism 3, a suction cup main body 301, a first mounting bracket 302, a suction cup air rod 303, a telescopic spring 304, a magnet 305, a material detection mechanism 4, a spring self-resetting pressure sensor 401, a second mounting bracket 402, an induction switch 403, a mounting cylinder 404, a movable rod 405, a reset spring 406, an adjustable DC electromagnetic coil 5, etc.

[0023] As Figures 1-4 shown, the present utility model provides a technical solution: an electromagnetic material taking device, including:

[0024] A cargo tray 1;

[0025] A horizontal bracket 2, located above the cargo tray 1;

[0026] A glass suction mechanism 3, provided with multiple groups. Each group of the glass suction mechanism 3 is equally spaced on both outer sides of the outer wall of the horizontal bracket 2. Each group of the glass suction mechanism 3 includes a mounting component and a suction cup main body 301. The mounting component is arranged on the horizontal bracket 2, and the suction cup main body 301 is arranged on the mounting component;

[0027] A material detection mechanism 4, arranged on the horizontal bracket 2. The material detection mechanism 4 includes four groups of sensing components and a spring self-resetting pressure sensor 401. Each group of sensing components is arranged on both outer sides of the outer wall of the horizontal bracket 2, and the spring self-resetting pressure sensor 401 is installed at the center of the bottom of the outer wall of the horizontal bracket 2;

[0028] An adjustable DC electromagnetic coil 5, provided with a plurality of them. Each adjustable DC electromagnetic coil 5 is installed at the bottom of the outer wall of the cargo tray 1.

[0029] In this embodiment: the cargo tray 1 is used to place glass, the horizontal bracket 2 is connected to the lifting device, and the glass suction mechanism 3 cooperates with the adjustable DC electromagnetic coil 5 to utilize the electromagnetic principle to realize the grabbing and placement of glass pieces, replacing the traditional cylinder drive method, avoiding the influence of air pressure fluctuations on the material picking process, improving the stability of material picking, achieving more precise speed control, ensuring that the glass pieces are not impacted during the material picking process, reducing the risk of breakage, and improving product quality. The suction cup body 301 on the mounting component can absorb the glass piece, and the sensing component is used to determine whether the corners of the glass piece are lifted up by the repulsive force of the coil. The spring self-resetting pressure sensor 401 is used to detect the contact position of the glass to be picked up and the repulsive force of the coil when it is energized, which is convenient for adjusting the DC coil current to calculate the repulsive force. The spring self-resetting pressure sensor 401 is a kind of sensor that uses the deformation of the spring to measure The sensor measures pressure and has an automatic reset function. When external pressure acts on the spring, the spring will deform. This deformation is converted into an electrical signal through the pressure sensitive element, thereby realizing the measurement of pressure. After the measurement is completed, the spring can automatically return to its initial state and prepare for the next measurement. The spring self-resetting pressure sensor 401 is lower than the four sets of sensing components and the suction cup body 301. When the device descends, the spring self-resetting pressure sensor 401 contacts the top layer of glass and issues a command to stop the horizontal support 2 from descending to avoid crushing the glass. Each adjustable DC electromagnetic coil 5 corresponds vertically to each set of glass suction mechanisms 3. The magnetic force generated by the coil mainly pushes the magnet 305 on the suction cup body 301 through the glass, generating a repulsive force. The magnet 305 drives the suction cup body 301 to rise, slowly balancing the atmospheric pressure, and better separating the two pieces of glass.

[0030] Specifically, each set of mounting components includes a first mounting frame 302, a suction cup gas rod 303, a telescopic spring 304 and a magnet 305. The first mounting frame 302 is installed on one side of the outer wall of the horizontal bracket 2, the suction cup gas rod 303 slides through the top of the outer wall of the first mounting frame 302, the telescopic spring 304 is fixedly arranged between the first mounting frame 302 and the suction cup gas rod 303, and the magnet 305 is fixedly arranged on the outer wall of the suction cup gas rod 303.

[0031] In this embodiment: the first mounting bracket 302 is used to install and place the suction cup gas rod 303, one end of the suction cup gas rod 303 is connected to the external air source or cylinder, one end of the telescopic spring 304 is fixedly set at the bottom of the outer wall of the first mounting bracket 302, and the other end of the telescopic spring 304 is fixedly set on the outer wall of the suction cup gas rod 303 near the bottom edge, and the telescopic spring 304 can provide buffering.

[0032] Specifically, each suction cup air rod 303 is fixedly connected to the top of the outer wall of the suction cup body 301 .

[0033] In this embodiment: The material of the sucker air rod 303 is iron. By adding the magnet 305, the repulsive force is increased in effect. Using the principle of like poles repelling each other, the glass sheet held by the sucker main body 301 can be better separated.

[0034] Specifically, each group of sensing components includes a second mounting bracket 402, an elastic component, and an induction switch 403. The second mounting bracket 402 is installed on one side of the outer wall of the horizontal bracket 2. The elastic component is arranged on the second mounting bracket 402, and the induction switch 403 is arranged on the elastic component.

[0035] In this embodiment: The second mounting bracket 402 is used for the installation and placement of the elastic component. The elastic component cooperates with the induction switch 403 to detect whether the corners of the glass sheet are separated from the next glass sheet.

[0036] Specifically, each group of elastic components includes a mounting cylinder 404, a movable rod 405, and a return spring 406. The mounting cylinder 404 is fixedly embedded in the top of the outer wall of the second mounting bracket 402. The movable rod 405 is slidably embedded in the inner wall of the mounting cylinder 404. The return spring 406 is fixedly arranged between the mounting cylinder 404 and the movable rod 405.

[0037] In this embodiment: When the corners of the two glass sheets are separated, the movable rod 405 will retract into the mounting cylinder 404, causing the movable rod 405 to touch the induction switch 403, and it can detect whether the corners of the two glass sheets are separated.

[0038] Specifically, each induction switch 403 is installed on the top of the inner wall of the mounting cylinder 404.

[0039] In this embodiment: When the movable rod 405 touches the induction switch 403, the corners of the two glass sheets are separated.

[0040] When in use, first place the glass on the loading tray 1, then drive the horizontal bracket 2 to descend and grab the material. The spring self-resetting pressure sensor 401 in the middle of the horizontal bracket 2 first senses the glass, generates pressure, and stops descending. At this time, the suction cup body 301 just touches the glass and starts adsorption. The machine does not move during this process. After all the suction cup pressure switches absorb the signal, the adjustable DC electromagnetic coil 5 at the corners of the glass is energized and works. The coil generates an upward electromagnetic force. Due to the repulsion between the same poles and the magnet 305, the suction cup body 301 is pushed upward by the electromagnetic force in the air, causing the telescopic spring 304 to contract. At this time, the air at the corners of the glass will enter the two pieces of glass to balance the atmospheric pressure. The movable rod 405 at the corner of the glass will retract into the installation tube 404, so that the movable rod 405 touches the sensing switch 403, proving that the four corners of the glass are separated. Then the remaining adjustable DC electromagnetic coil 5 is energized from both sides to the middle. Since the current is a slowly increasing process, the electromagnetic force will also increase accordingly, and the glass will slowly separate from the glass below until the spring self-resetting pressure sensor 401 feels a greater pressure, and the grasped glass is completely separated from the lower glass, allowing the grasping device to rise. During the rising process, the magnetic field will gradually weaken, and the glass will slowly reset along with the telescopic spring 304. The pressure of the spring self-resetting pressure sensor 401 becomes smaller, and the device grasps and places it on the conveyor line.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
