Description

Technical Field

[0001] The utility model relates to an automatic sticker attaching device, belonging to the technical field of sticker attaching devices. Background Technique

[0002] A sticker is the name of a tape specially designed to facilitate the removal of the protective film attached to a liquid crystal panel, also known as a film tearing label, a tearable paper, etc. It is also called a tear handle or a lift handle. Using a sticker to remove the protective film is convenient, time-saving and leaves no trace. A sticker attaching device is required when attaching a sticker.

[0003] According to the patent with the publication number CN215753240U, an automatic sticker attaching device is disclosed, which includes a roller, a conveyor belt, a carrier table, a suction nozzle, an image sensor, and a guide shaft. It is characterized in that the sticker is placed on the carrier tape, and the liquid crystal display screen is placed on the conveyor belt. The suction nozzle uses negative pressure to adsorb and grab the sticker, and the image sensor is used to align the sticker and the liquid crystal display screen. Finally, the suction nozzle descends and presses to complete the attachment. When the above device is used, although it can facilitate the attachment of the sticker and reduce the labor intensity of workers, only pressing down the suction nozzle cannot effectively ensure that the sticker is completely attached to the protective film of the display screen, resulting in a poor attachment effect of the sticker. It is easy to have incomplete adhesion of the sticker, and dust etc. adheres to the adhesion layer, which in turn affects the subsequent normal use. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic sticker attaching device, which can effectively improve the attachment effect of the sticker, avoid affecting the subsequent normal use of the sticker, and thus effectively improve the practicability of the device, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic sticker attaching device includes a base. One side top of the base is fixedly provided with a workbench, and the other side top of the base is rotatably provided with a support. The support is located at the rear side of the base. The top of the support is fixedly provided with a support bracket I. A cylinder I is fixedly embedded through the support bracket I. The output end of the cylinder I is fixedly connected with a mounting plate. The bottom end of the mounting plate is fixedly provided with a suction nozzle. A limiting block is fixedly provided at the rear side top of the workbench. A support bracket II is slidably provided at the top of the base near the support bracket I. The bottom end of the horizontal part of the support bracket II is fixedly provided with a cylinder II. The output end of the cylinder II is fixedly connected with a pressure roller.

[0007] Further, an elastic pad is fixedly sleeved around the limiting block.

[0008] Further, a cavity is formed inside one side of the base close to the support. A rotating shaft is rotatably provided on the inner wall of the bottom end of the cavity. The top end of the rotating shaft extends above the base and is fixedly connected to the bottom end of the support. A first motor is fixedly provided on the inner wall of the bottom end of the cavity. Gears are fixedly provided at the output end of the first motor and on the upper part of the rotating shaft respectively. The two gears are meshed with each other.

[0009] Further, an annular rotating groove is formed at the bottom end of the support. A rotating block is rotatably provided around inside the annular rotating groove. The bottom end of the rotating block is fixedly connected to the top end of the base.

[0010] Further, a sliding groove is formed at the top end of one side of the workbench close to the first support. A second motor is fixedly provided at the front side of the workbench. The output end of the second motor is fixedly connected to a screw rod. The rear end of the screw rod extends into the sliding groove. A sliding block is sleeved on the screw rod in a threaded manner. The top end of the sliding block is fixedly connected to the bottom end of the second support.

[0011] Further, the sliding block is slidably connected to the sliding groove. A threaded sleeve matching the screw rod is fixedly embedded through the sliding block.

[0012] Further, an anti-slip pad is fixedly provided at the bottom end of the base.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By providing a pressing roller, when in use, the easy-to-tear sticker is taken off from the carrier tape through a suction nozzle, and the easy-to-tear sticker is rotated to directly above the display screen, and then pressed down onto the protective film of the display screen. Then, the pressing roller is pushed downward by the second cylinder to an appropriate height. At the same time, the second support drives the pressing roller to move back and forth, so that the easy-to-tear sticker can be tightly pressed on the protective film of the display screen, improving the sticking quality of the easy-to-tear sticker. The present utility model can effectively improve the sticking effect of the easy-to-tear sticker, avoid affecting the subsequent normal use of the easy-to-tear sticker, and thus effectively improve the practicability of the device.
