It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0021] like Figures 1 to 2As shown, the preferred embodiment of the present invention provides an electromagnetic semiconductor gripper, which includes a base 100, an upper chuck assembly 200, a lower chuck assembly 300, an electromagnet assembly 400, a first pull rod spring 500 and a second pull rod spring 600. The base 100 is provided with a first rotation fulcrum 700 and a second rotation fulcrum 800. The lower chuck assembly 300 is rotatably connected to the base 100 through the first rotation fulcrum, and the upper chuck assembly 200 is rotatably connected to the base 100 through the second rotation fulcrum 800. The first pull rod spring 500 is arranged at the rear end of the upper chuck assembly 200. Between the lower chuck assembly 300 and the base 100, the second pull rod spring 600 is arranged between the front end of the lower chuck assembly 300 and the base 100, and the upper chuck assembly 200 is provided with a roller 900, and the roller 900 can be against the upper plane of the base 100, and the roller 900 is arranged on the side close to the first pull rod spring 500, and the electromagnet assembly 400 includes an electromagnet 401 and an iron sheet 402, the electromagnet 401 is fixed on the lower chuck assembly 300, and the iron sheet 402 is fixed on the upper chuck assembly 200, and the electromagnet 401 and the iron sheet 402 are arranged opposite to each other.

[0022] During specific use, the gripper is installed next to the feeding guide rail. When the sheet reaches between the upper clamping head 202 assembly 200 and the lower clamping head assembly 300, the electromagnet 401 is energized to generate magnetic force. The electromagnet 401 and the adjustment plate attract each other so that the upper clamping head assembly 200 and the lower clamping head assembly 300 are clamped and closed. The gripper grabs the sheet and moves it to the desired position. At this time, the electromagnet 401 is de-energized. Due to the setting of the first pull rod spring 500 and the second pull rod spring 600, the upper clamping head assembly can be clamped. 200 and the lower chuck 302 assembly 300 are opened and reset to prepare for the next clamping. Therefore, the utility model generates magnetic force by energizing the electromagnet 401 to drive the clamping action, which can ensure the clamping force and is not easy to be misplaced. At the same time, the upper and lower positions of the adjusting piece are adjusted by adjusting the screw to adjust the distance between the adjusting piece and the electromagnet 401, so that the opening angle of the upper chuck assembly 200 and the lower chuck assembly 300 can be adjusted to adapt to materials of different specifications, and has strong compatibility.

[0023] In this embodiment, the upper chuck assembly 200 includes an upper chuck mounting seat 201 and an upper chuck 202. The rear end of the upper chuck mounting seat 201 is rotatably connected to the base 100 through the second rotation fulcrum 800, and the upper chuck 202 is fixed to the front end of the upper chuck mounting seat 201.

[0024] For example, an adjusting member 403 is threadedly connected to the mounting base 201 of the upper chuck 202, and the lower end of the adjusting member 403 is fixedly connected to the iron sheet 402. Thus, by rotating the adjusting member 403, the distance between the iron sheet 402 and the electromagnet 401 can be adjusted when the clamp is in the open state, thereby adjusting the opening and closing angle of the clamp to adapt to different sizes of the sheet, and the adaptability is strong.

[0025] For example, in order to facilitate the connection of the first pull rod spring 500, a first connecting portion 203 is extended from the upper clamp mounting seat 201, and the first connecting portion 203 is provided with a first through hole for cooperating and connecting with the first pull rod spring 500. A second connecting portion 101 is provided on the base 100, and the second connecting portion 101 is provided with a second through hole for cooperating and connecting with the first pull rod spring 500.

[0026] Exemplarily, the lower chuck assembly 300 includes a lower chuck mounting seat 301 and a lower chuck 302 , the rear end of the lower chuck mounting seat 301 is rotatably connected to the base 100 via the first rotation fulcrum, and the lower chuck 302 is fixed to the front end of the lower chuck mounting seat 301 .

[0027] For example, a proximity switch 204 is provided on the upper chuck mounting base 201 to prevent the upper chuck 202 and the lower chuck 302 from colliding, thereby ensuring the service life of the clamp.

[0028] Exemplarily, an electromagnetic semiconductor gripper further includes a slide 1000 , and the base 100 is slidably connected to the slide 1000 .

[0029] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
