## Background
BACKGROUND
1. Technical Field
The present disclosure generally relates to a stripping device, and particularly to an apparatus for stripping release papers from workpieces applied during production.
2. Description of the Related Art
Release papers are usually adhered to workpieces for protecting the workpieces from damage in transport, and twin adhesives with release papers are adhered to workpieces for assembling with other structures in assembly. The release papers are usually manually stripped off from the workpieces. However, efficiency of the manual way is relatively low.
Therefore, there is room for improvement within the art.

In assembly, one pushing mechanism 30 is firstly assembled to the base 10 with the following steps: The supporting members 31, the guiding rails 32 are mounted on the base 10. The slider 33 is positioned on the two guiding rails 32. The guiding member 34 is fixed on the supporting member 31. The resisting member 35 is installed on the supporting member 31 adjacent to the guiding member 34 above the first and second recessing grooves 315, 3311. Each pushing post 373 passes through one penetrating hole 313. Then one pushing mechanism 30 is assembled to the base 10, and the other pushing mechanism 30 is assembled with the same steps. The bracket 51 is assembled with the base 10. The driving member 52 is fixedly connected to the base 10. The pushing member 53 is connected to the driving member 52 under the through hole 113. The two suction driving members 55 are mounted on the mounting board 515 away from the supporting pillars 513. The suction members are connected to the two suction driving members 55. The third driver 71 is positioned on the second installation surface 13 and is connected to the bottom board 511. The first buffer member 73 is positioned on the second installation surface 13. The second buffer member 75 mounted on the second installation surface 13 opposite to the first buffer member 73.
In use, one workpiece 200 is received in the receiving portion 341 and drops into the first guiding groove 312. The pushing posts 373 push the workpiece 200 to the second guiding groove 331 (as shown in FIG. 4). The release paper 201 is above the first and second recessing grooves 315, 3311. The driving member 52 drives the pushing member 53 to extend through the penetrating hole 113, the first and second recessing grooves 315, 3311 to clamp the release paper 201 between the pushing member 53 and the resisting member 35. The suction members 553 suck the workpiece 200 and move relative to the base 10, such that the release paper 201 is stripped off. The third driver 71 drives the bracket 51 to move relative to the base 10, transporting the workpiece 200 to the next workstation. The first buffer member 73 resists the bottom board 511 and the second driver 38 drives the slider 33 slide along the guiding rails 32. The pushing member 53 releases the release paper 201, such that the release paper 53 slides into the bottom board 511 via the through hole 113. The bracket 51 returns to the original position and resists against the second buffer member 75.
As described above, the stripping mechanism 50 engages with the pushing mechanisms 30 to clamp a part of the release paper 201 between the stripping mechanism 50 and the pushing mechanisms 30. The suction members 553 suck the workpiece 200 and moves the workpiece 200 relative to the base 10, such that the release paper 201 is stripped off from the workpiece 200 automatically.
In other embodiments, the number of the pushing mechanisms 30 is not limited to two, it can be one, three or more. The number of the supporting pillars 513 is not limited to three, it can be one, two or more, and the number of the guiding holes 312 corresponds to the number of the supporting pillars 513. The number of the pushing members 373 of each first driver 37 is not limited to two, it can be one, three or more, and the number of the penetrating holes 313 corresponds to the number of the pushing members 373.
