[0037] See also Figure 2 , Figure 2 A three-dimensional schematic diagram of a film peeling mechanism of some embodiments of the present disclosure is shown. In some embodiments, the rotating mechanism 21 of the film peeling mechanism 20 may also include a roller driving mechanism, which may include, for example, a driving actuator 215 such as a motor for driving the roller to rotate.

It can be understood by those skilled in the art that the present disclosure does not limit the specific mode of the rotation transmission at this place, and the pulley transmission here can be transmitted in the form of ordinary belts or synchronous belts, or the belt and pulley combination can be replaced by a gear combination or other rotation driving mechanism, as long as it can transmit the rotational motion of the rotating output shaft 13 of the driving actuator 215.

[0038] In some embodiments, a rotating shaft hole penetrating the plate surface may be formed on the ear plate of the first support frame, and the rotating shaft of the film tearing roller 23 extends into the rotating shaft hole.

[0040] See also Figure 3 , Figure 3 A partial three-dimensional schematic diagram of a film tearing mechanism of some embodiments of the present disclosure is shown. In some embodiments, the film tearing mechanism may also include a horizontal driving mechanism 40 for driving the film-bearing product 50 to move horizontally relative to the film tearing roller 23 and the film coating roller 33. The horizontal driving mechanism 40 may, for example, include a horizontal fixing portion 43, and a horizontal moving portion 41 capable of horizontal movement relative to the horizontal fixing portion 43. The horizontal driving mechanism 40 may, for example, include a horizontal transverse slide assembly, the horizontal fixing portion 43 may, for example, include a slide body of the slide assembly, and the horizontal moving portion 41 may include a moving table capable of moving relative to the main body along a horizontal guide rail.

[0041] The mobile platform may be provided with a loading portion 45 for carrying the coated product 50. The loading portion 45 may be, for example, roughly in the shape of a plate, which is horizontally arranged on the vertical upper side of the mobile platform, and the side facing away from the mobile platform is used to carry the coated product 50. The loading portion 45 may include an upper plate and a lower plate arranged overlapping in the vertical direction. The upper surface of the upper plate may be provided with a plurality of vacuum positioning holes for adsorbing the coated product 50, and the vacuum positioning holes may penetrate the surface of the upper plate in the vertical direction. The portions of the lower plate adjacent to the upper plate may be arranged to be sealed relative to each other. The interior of the lower plate may be provided with a connecting channel connected to the vacuum positioning holes of the upper plate, which is connected to a plurality of vacuum positioning holes on the one hand, and may extend to a side of the lower plate and be open on the other hand. Thus, vacuum adsorption of the coated product 50 may be achieved by providing a vacuum generating device connected to the connecting channel.

[0042] In some embodiments, the frame 18 for fixing the film peeling mechanism may include, for example, an upper frame 181 and a lower frame 183, wherein the upper frame 181 and the lower frame 183 are fixedly connected relative to each other, the upper frame 181 includes a main vertical plate 16, and the lower frame 183 includes a base 49. The main vertical plate 16 is located at the vertical upper side of the upper frame 181, so that the first driving mechanism 10, the film peeling mechanism 20 and the film coating mechanism 30 of the film peeling mechanism are fixedly arranged at the vertical upper side of the horizontal driving mechanism 40. At the same time, the film peeling roller 23 of the film peeling mechanism 20 and the film coating roller 33 of the film coating mechanism 30 are arranged at the vertical upper side of the loading part 45 of the horizontal driving mechanism 40. When the horizontal moving part 41 of the first driving mechanism 10 descends in the vertical direction, the film peeling roller 23 can be attached to the upper surface of the coated product 50 on the loading part 45 to perform the film peeling operation. Further, the coating roller 33 can move downward in the vertical direction under the drive of the second driving mechanism 31, and press against the upper surface of the coated product 50, so as to cover the torn coating back to the coated product 50. It can be understood by those skilled in the art that the present disclosure does not limit the specific composition form of the horizontal driving mechanism 40, for example, it can be formed as a transmission belt including a plurality of loading parts 45, or a turntable including a plurality of loading parts 45, etc.

[0043] When the film-tearing mechanism is used to tear off the film of the film-coated product 50, the film-coated product 50 can be firstly placed on the upper surface of the loading part 45, wherein the film-coated side of the film-coated product 50 is placed upward. After the product 50 is placed, the vacuum generating device connected to the loading part 45 is started to adsorb and position the film-coated product 50 through the vacuum positioning hole. Further, the horizontal moving part 41 of the first driving mechanism 10 moves downward in the vertical direction until the film-tearing roller 23 can contact the film on the upper surface of the film-coated product 50, and the vacuum generating device connected to the film-tearing roller 23 can be started to adsorb the film. Thereafter, the moving platform of the horizontal driving mechanism 40 moves in a first horizontal direction perpendicular to the rotation axis of the film-tearing roller 23, and at the same time, the rotating mechanism 21 of the film-tearing mechanism 20 drives the film-tearing roller 23 to rotate. Thus, as the tearing drum 23 rotates and the movable table moves horizontally, the coating film adsorbed on the surface of the tearing drum 23 is torn off from the coated product 50 and is wound and fixed on the surface of the tearing drum 23 .

[0044] Furthermore, after tearing off the peritoneum on the surface of the film-coated product 50, the first driving mechanism 10 can drive the film-tearing mechanism 20 and the film-coating mechanism 30 to lift and move away from the film-coated product 50 in the vertical direction, so that the film-coated product 50 can be processed accordingly. For example, in some embodiments, the film-coated product 50 is a display panel module covered with a process film. After tearing off the process film through the above-mentioned action sequence, the bare screen exposed by the display panel module can be inspected for surface defects.

[0045] After the corresponding processing steps are completed, the moving platform of the horizontal driving mechanism 40 can move horizontally in a second horizontal direction opposite to the first horizontal direction, and the rotating mechanism 21 of the film tearing mechanism 20 rotates in the opposite direction, so that the film wound on the film tearing roller 23 is attached back to the surface of the film-coated product 50. At the same time, the moving end 312 of the second driving mechanism 31 of the film-coating mechanism 30 can move toward the loading part 45 in the vertical direction, so that the film-coating roller 33 can be close to the surface of the film-coated product 50. When the moving platform moves in the second horizontal direction and the film is attached back to the surface of the film-coated product 50, the film-coating roller 33 can follow the movement of the film-tearing roller 23 to attach the film on the surface of the film-coated product 50 tightly, so as to prevent the film on the film-coated product 50 from loosening.

[0046] After the film coating process is completed, each moving mechanism can return to its original position, the product 50 on the carrying part can be taken out, and the next product to be processed 50 can be placed. In addition, during the entire film coating and film tearing process, the pressure adjustment mechanism 19 arranged between the first driving mechanism 10 and the first support frame can limit the maximum pressure of the film coating roller 33 and the film tearing roller 23 on the film coated product 50 to prevent the product 50 from being damaged by excessive pressure.

[0047] According to the film-tearing mechanism of some embodiments of the present disclosure, the film-tearing mechanism and the film-laminating mechanism of the moving part are respectively fixedly arranged on the first driving mechanism, and the film-tearing mechanism can tear off the film under the drive of the rotating mechanism, and the film-laminating mechanism can be driven by the second driving mechanism to move up and down independently. Therefore, the film-tearing mechanism can realize efficient film-tearing action with a compact structure, reduce unnecessary consumables, and reduce process production costs.

[0048] See also Figure 7 , Figure 7 200 is a three-dimensional schematic diagram of a film peeling system according to some embodiments of the present disclosure. The film peeling system 200 may include, for example, a film peeling mechanism 100 according to some embodiments of the present disclosure. One or more film peeling mechanisms 100 may be disposed on a frame 300 .
