Description
Technical Field
[0001] The utility model relates to the technical field of adhesive stripping, in particular to a device for stripping adhesive of a screen. Background Art
[0002] The LED module of the bracelet is composed of an LED bottom cover at the lower layer and an LED FPC at the upper layer, which are stacked and bonded to each other. During the bracelet production process, the LED module needs to be further stacked and bonded to another LED top cover. Before the bonding operation, the adhesive film at the bottom of the LED bottom cover needs to be torn off by an adhesive stripping device.
[0003] Most of the existing adhesive stripping devices can only strip adhesive films of the same size. When adhesive films of other sizes need to be stripped, other equipment needs to be replaced. The process of replacing equipment affects work efficiency and increases the cost of use. The scope of application is low and further improvement is needed. For this reason, we propose a screen-fitting adhesive stripping device. Utility Model Content

[0007] Preferably, the stripping component includes a motor and a third suction cup, the motor is installed at the front end of the top plate, the output end of the motor extends into the third rectangular groove and is fixedly connected to a forward and reverse threaded rod, the outer surface threaded sleeve of the forward and reverse threaded rod is provided with two moving blocks symmetrically distributed front and back, the lower ends of the two moving blocks are each installed with a second suction cup, and the third suction cup is installed in the middle of the left end of the top plate.
[0008] Preferably, the rear end of the forward and reverse threaded rod is movably connected to the rear wall of the third rectangular groove, and the left end and the right end of the moving block are slidably connected to the left wall and the right wall of the third rectangular groove respectively.
[0009] Preferably, the straightening component includes a bidirectional cylinder, which is installed on the lower left end of the base plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. By setting a peeling component, it is convenient to peel off adhesive films of different sizes. When the screen size is large, the output end of the control motor drives the positive and negative threaded rods to rotate, and the positive and negative threaded rods drive the two moving blocks to move away from each other. The two moving blocks respectively drive the two second suction cups to move away from each other, so that the two second suction cups can adsorb the edges of the adhesive film, which can facilitate the peeling of the adhesive film. When peeling off the adhesive film of a smaller size, the control motor rotates in the opposite direction, so that the two second suction cups are close to each other, and the adhesive film of a smaller size can be peeled off without replacing other equipment, thereby ensuring work efficiency, reducing use costs, and improving the scope of application of the device;
[0015] 2. The position of the workpiece can be adjusted by setting the adjustment component. When the second infrared sensor detects that the workpiece moves between the push plates, the conveyor is controlled to stop running, and the two conveying ends of the two-way cylinder are controlled to shorten. At the same time, the two push plates are driven close to each other. The two push plates push the screen to the center of the two conveyors, which makes it convenient for the subsequent second suction cup to accurately approach the edge of the adhesive film, ensuring the subsequent peeling effect and reducing the number of rework.
