Description

Technical Field

[0001] The utility model relates to the field of tooling, and more particularly to a tooling for rotating a display screen. Background Art

[0002] The display screen is fragile. Manual rotation during assembly is very likely to cause uneven force and damage the screen, affecting its use.

[0003] Chinese Patent Authorization Announcement No.: CN216901193U provides a tooling for rotating a liquid crystal display screen. This solution positions the liquid crystal display screen through a rotatable liquid crystal display screen back plate and a stop block, which can reduce the bending of the product when it is rotated and effectively prevent the product from falling or being crushed by people during the rotation process, resulting in damage and scrapping of the product. The LCD display screen rotation is efficient, stable and reliable. However, in this comparative patent, only the display screen can be rotated. Such a structure cannot achieve a true flip of the display screen, that is, the front side remains the front side, and the back side remains the back side.

[0035] The fixing mechanism 3 includes a vacuum pump 301, a first hose 302, a second hose 303, a first vacuum suction cup 304, and a second vacuum suction cup 305. The vacuum pump 301 is fixedly installed inside the base 1. One end of the first hose 302 is fixedly connected to the vacuum pump 301, and the other end of the first hose 302 is fixedly connected to the first vacuum suction cup 304. One end of the second hose 303 is fixedly connected to the vacuum pump 301, and the other end of the second hose 303 is fixedly connected to the second vacuum suction cup 305. In this solution, by providing the vacuum pump 301, when the first rotating plate 210 and the second rotating plate 223 cooperate to rotate, the electromagnetic valve of the first hose 302 is closed, causing the first vacuum suction cup 304 to lose its adsorption capacity. At the same time, the electromagnetic valve of the second hose 303 is opened, and the display screen body 4 is adsorbed on the upper end of the second vacuum suction cup 305, thereby rotating the display screen body 4.

The first vacuum suction cup 304 and the second vacuum suction cup 305 are arranged in an array. By using anti-static suction cups, this solution can avoid static damage to the display screen, thereby causing the possibility of damage to the display screen.

[0037] The display screen body 4 is located on the upper end of the first vacuum suction cup 304 , and the display screen body 4 and the first vacuum suction cup 304 are sucked together.

[0038] Working principle: First, the first pneumatic push rod 206 is activated to drive the first connecting rod 205 to move forward, thereby driving the first connecting seat 211 to move forward, thereby driving the first slider seat 202 to move forward along the first slide groove 201, thereby driving the second connecting rod 207 to push the first rotating plate 210 to rotate around the second rotating shaft 212, so that the rotation angle of the first rotating plate 210 can be adjusted between 0 degrees and 90 degrees. After the first rotating plate 210 is adjusted to 90 degrees, the second pneumatic push rod 219 is activated at the same time to drive the third connecting rod 218 to move forward, thereby driving the second connecting seat 224 to move forward, thereby driving the second slider seat 215 to move forward along the second slide groove 214, thereby driving the fourth connecting rod 220 pushes the second rotating plate 223 to rotate around the fourth rotating shaft 225, so that the rotation angle of the first rotating plate 210 can be adjusted between 0 degrees and 90 degrees. After the second rotating plate 223 is adjusted to 90 degrees, the vacuum pump 301 is set. When the first rotating plate 210 and the second rotating plate 223 rotate together, the electromagnetic valve of the first hose 302 is closed to make the first vacuum suction cup 304 lose its adsorption ability. At the same time, the electromagnetic valve of the second hose 303 is opened to adsorb the display body 4 on the upper end of the second vacuum suction cup 305. Then, the first pneumatic push rod 206 and the second pneumatic push rod 219 are started to adjust the first rotating plate 210 and the second rotating plate 223 back to 0 degrees to rotate the next display body 4.
