DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] The utility model provides Figure 1-Figure 5 The device for attaching EVA shading cotton shown in the figure includes a body 101 adsorption mechanism, a moving mechanism and an adjustment mechanism. A conveyor belt 102 is provided inside the body 101. The conveyor belt 102 is used to transport the screen. The adsorption mechanism is provided inside the body 101. The moving mechanism is provided inside the body 101. The first moving mechanism is used to move the adsorption mechanism. The adjustment mechanism is provided inside the adsorption mechanism. An EVA shading cotton winding mechanism is also provided inside the body 101. There are two winding rollers in total. The EVA shading cotton is wound on one of the winding rollers and then the EVA is pulled. The shading cotton is connected to another winding roller, and the EVA shading cotton can be moved by rotating the two winding rollers. The moving mechanism drives the adsorption mechanism to peel off the shading cotton from the release film, and then the moving mechanism drives the adsorption mechanism to move to the top of the conveyor belt 102, so that the adsorption mechanism sticks the shading cotton to the screen at the top of the conveyor belt 102. A detection camera can also be set inside the body 101 to prevent the adsorption mechanism from sticking the shading cotton that is incorrectly positioned or damaged to the screen, thereby avoiding manual mounting, thereby improving the mounting quality and mounting effect.

[0045] Among them, the adsorption mechanism includes a suction cup 201 and a suction machine 202, the adjustment mechanism is arranged inside the suction cup 201, the top of the suction cup 201 is provided with a lifting mechanism, the suction machine 202 is arranged above the suction cup 201, and a connecting mechanism is provided between the suction cup 201 and the suction machine 202. With the cooperation of the connecting mechanism, the suction machine 202 can generate negative pressure inside the suction cup 201, thereby peeling the shading cotton from the release film through the suction cup 201, and then the movement of the suction cup 201 can drive the shading cotton to move until the shading cotton is attached to the corresponding position of the screen. At this time, the suction machine 202 stops sucking, and no negative pressure is generated inside the suction cup 201. The suction cup 201 no longer has an adsorption effect on the shading cotton, and the suction cup 201 can be separated from the shading cotton.

[0046] Among them, the lifting mechanism includes a cylinder 205 and a connecting seat 206. The connecting seat 206 is connected to the moving mechanism. The suction machine 202 is installed on the front of the connecting seat 206. The cylinder 205 is installed at the bottom end of the connecting seat 206. The output end of the cylinder 205 is connected to the top end of the suction cup 201 for transmission. The operation of the cylinder 205 can drive the suction cup 201 to move up and down, thereby improving the convenience of the adsorption mechanism.

[0047] Among them, the connecting mechanism includes an outer sleeve 203, a connecting pipe 204 and a sealing ring 207. The outer sleeve 203 is connected to the output end of the suction machine 202. The connecting pipe 204 is fixedly inserted and connected to the top of the suction cup 201. The outer wall of the connecting pipe 204 is movably inserted and connected to the inner wall of the outer sleeve 203. The sealing ring 207 is attached to the inner wall of the outer sleeve 203. The inner wall of the sealing ring 207 and the outer wall of the connecting pipe 204 are interference fit. By moving the connecting pipe 204 through the sealing ring 207, the cylinder 205 can stably drive the suction cup 201 to rise and fall. At the same time, the negative pressure generated by the suction machine 202 can be stably transmitted to the suction cup 201 through the outer sleeve 203 and the connecting pipe 204, thereby ensuring the stability of the adsorption mechanism.

[0048] The adjusting mechanism includes a connecting cavity 301 and a rotating ring 304.

The second connecting holes 303 are opposite to the connecting holes 305. The bottom end of the rotating ring 304 is provided with a rotating mechanism, and the bottom end of the rotating ring 304 is provided with a positioning mechanism. When a smaller EVA shading cotton needs to be adsorbed, the rotating ring 304 can be used to adjust the position of the adjusting mechanism. The ring 304 rotates so that the connecting hole 305 and the second connecting hole 303 no longer overlap. At this time, the suction cup 201 is connected to the outside world through the multiple first connecting holes 302 located in the inner circle at the bottom end, and the smaller shading cotton can be adsorbed through the multiple first connecting holes 302. When it is necessary to adsorb larger shading cotton, the rotating ring 304 is rotated so that the connecting hole 305 and the second connecting hole 303 overlap. At this time, the first connecting holes 302 in the inner circle of the suction cup 201 and the second connecting holes 303 in the outer circle are connected to the outside world, and the larger shading cotton can be adsorbed, thereby improving the applicability of the adsorption mechanism.

[0049] The cam 402 is fixedly connected to the bottom end of the connecting rod 401, and one end of the cam 402 is rotatably connected to the inner wall of the connecting cavity 301.

One end of the cam 402 passes through the inner wall of the connecting cavity 301 and is fixedly connected to the top end of the handle 404. The handle 404 is rotated in the slot 403, and the swivel 304 is rotated in the connecting cavity 301 through the connection between the cam 402 and the connecting rod 401, thereby improving the convenience of operation of the adjustment mechanism. In addition, the connection of the connecting rod 401 is provided so that the bottom end of the suction cup 201 has no protrusion, so that the adsorption of the shading cotton by the suction cup 201 will not be affected, thereby ensuring the stability of the adsorption mechanism.

[0050] Among them, the sides of the bottom end of the rotating ring 304 are fixedly connected with the first sealing ring 501, and the bottom end of the first sealing ring 501 is interference fit with the inner wall of the connecting cavity 301.

Through the setting of the first sealing ring 501 and the second sealing ring 502, when smaller shading cotton is adsorbed, the second connecting hole 303 is not prone to leakage.

[0051] The positioning mechanism includes a steel ball 602 and a spring 604. The bottom end of the rotating ring 304 is provided with a movable groove 601. The steel ball 602 is movably clamped in the inner part of the movable groove 601. The spring 604 is arranged between the top of the steel ball 602 and the inner wall of the movable groove 601. The top of the inner wall of the connecting cavity 301 is provided with a plurality of clamping holes 603. The outer wall of the steel ball 602 is fitted with the inner wall of the clamping hole 603. When the rotating ring 304 rotates, the connecting hole 305 overlaps with the second connecting hole 303. When closed, the steel ball 602 will be stuck in the corresponding hole 603. When the rotating ring 304 rotates so that the connecting hole 305 and the second connecting hole 303 do not overlap, the steel ball 602 will be stuck in the other corresponding hole 603. When stuck in, the elastic effect of the reed 604 and the technical material of the steel ball 602 will cause the steel ball 602 to be stuck in the hole 603, which will produce a knocking sound, thereby prompting the staff and allowing the staff to understand the adjustment status of the adjustment mechanism.

[0052] Among them, the moving mechanism includes a first slide rail 701, a slide seat 702 and a second slide rail 703. The first slide rail 701 is fixedly arranged inside the body 101, the slide seat 702 is slidably arranged at the top of the first slide rail 701, the second slide rail 703 is fixedly connected to the top of the slide seat 702, and the connecting seat 206 is slidably arranged on the front of the second slide rail 703. The slide seat 702 can move on the first slide rail 701, and the connecting seat 206 can be moved on the second slide rail 703, so that the adsorption mechanism can move in multiple directions, thereby improving the convenience of the mounting device.
