[0015] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0016] The utility model discloses a polarizer peeling device, see Figure 1, which includes a bracket 1, and side support plates 2 are fixed on the left and right ends of the bracket 1 respectively, and a roller shaft 3 and a rubber shaft 4 parallel to each other are arranged between the two side support plates 2, and the gap between the roller shaft 3 and the rubber shaft 4 is used to pass the polarizer, and the width of the gap is less than the thickness of the polarizer, and the two ends of the roller shaft 3 are respectively rotatably connected to the two side support plates 2, and the two ends of the rubber shaft 4 are respectively rotatably connected to the two side support plates 2, and the roller shaft 3 and the rubber shaft 4 are respectively rotatably connected to the two side support plates 2, and the roller shaft 3 and the rubber shaft 4 are connected by a gear assembly 5. At least one side support plate 2 is provided with a driving shaft 6 that is connected to a preset driving mechanism, and the driving shaft 6 is connected to the gear assembly 5. When the driving shaft 6 is running, the gear assembly 5 drives the roller shaft 3 and the rubber shaft 4 to rotate synchronously in opposite directions, and the cooperation of the roller shaft 3 and the rubber shaft 4 applies a peeling force to the polarizer.

[0017] When peeling the polarizer, the above-mentioned device can first lift up a corner of the polarizer at the corner of the display screen. In order to facilitate lifting up a corner of the polarizer and subsequent peeling work, it is best to preheat the display screen and the polarizer first. At an appropriate temperature, align the lifted corner of the polarizer and send it into the gap between the roller 3 and the glue shaft 4. During the operation of the driving shaft 6, the roller 3 and the glue shaft 4 are driven by the gear assembly 5 to rotate synchronously in opposite directions. Under the joint action of the relative rotation of the roller 3 and the glue shaft 4, the peeling force is fully applied to the polarizer, so that the polarizer is gradually peeled off from the display screen through the gap between the roller 3 and the glue shaft 4. Compared with the peeling method using a blade and alcohol in the prior art, the utility model can assist the operator to peel off the polarizer quickly and automatically, while avoiding damage to the display screen, and the peeling work efficiency is higher.

[0018] In order to drive the roller shaft 3 and the rubber shaft 4 to rotate synchronously in opposite directions, in this embodiment, the gear assembly 5 includes a first gear 50 and a second gear 51 that mesh with each other. The first gear 50 and the second gear 51 are coaxially fixed to the roller shaft 3 and the rubber shaft 4, respectively, and a driving gear that meshes with the first gear 50 or the second gear 51 is provided on the driving shaft 6. The first gear 50 and the second gear 51 are gears of the same specifications, thereby ensuring that the roller shaft 3 and the rubber shaft 4 rotate synchronously.

[0019] In this embodiment, a sprocket 60 is fixed to the end of the drive shaft 6, and the sprocket 60 is connected to the preset drive mechanism through a chain transmission. The preset drive mechanism can be a motor chain drive mechanism, which has advantages such as strong driving ability.

[0020] As a preferred embodiment, two parallel strip-shaped blocks 7 are fixed on the bracket 1, and the roller shaft 3 and the rubber shaft 4 are both located between the two strip-shaped blocks 7. Further, the top of the strip-shaped block 7 is flush with the roller shaft 3 and the rubber shaft 4, or the top of the strip-shaped block 7 protrudes above the roller shaft 3 and the rubber shaft 4.

[0021] In the above structure, the two strip-shaped blocks 7 are used to support the display screen, that is, when the polarizer enters the gap between the roller 3 and the rubber shaft 4, the display screen is blocked above the roller 3 and the rubber shaft 4, thereby ensuring that the polarizer is gradually peeled off from the display screen under the rolling drive of the roller 3 and the rubber shaft 4.

[0022] It does not play a reliable supporting role. This embodiment includes a support 8 fixedly connected to a preset machine, and the bracket 1 is fixed to the upper end of the support 8.

[0023] In order to meet the preheating requirements for the display screen and the polarizer, the present embodiment includes a preheating box 9 for preheating the display screen with the polarizer attached thereto, and the preheating box 9 is provided with a temperature controller 90. In practical applications, the support 8 is preferably arranged adjacent to the preheating box 9 to prevent the heat from dissipating rapidly and affecting the peeling efficiency.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
