The micro-motion mechanism drives the peeling component to move horizontally, vertically or simultaneously, so as to be used for finely adjusting the position of the peeling component during peeling. The fine adjustment means that the micro-motion mechanism and the main motion support seat have the same driving direction, the main motion support seat is used for controlling the motion of a large distance, and the micro-motion mechanism is used for adjusting the small distance range, so that the influence of motion inertia on the position of the stripping part is reduced.

With reference to fig. 2, as a preferred embodiment, the film peeling and removing device of the present embodiment includes a workbench 410, a main motion supporting base, a micro-motion mechanism, a peeling member, and a clamping jaw mechanism 320, wherein the workbench 410 is used for fixing a display screen 500; the main motion supporting seat is used for providing vertical and horizontal motion, a base 131 is arranged at the motion tail end of the main motion supporting seat, and the micro-motion mechanism and the clamping jaw mechanism 320 are arranged on the base 131; a stripping component is arranged at the moving tail end of the micro-motion mechanism, the micro-motion mechanism drives the stripping component to move in the vertical and horizontal directions, and the waste edge film 504 to be stripped on the display screen 500 is stripped and removed; the gripper mechanism 320 is provided for removing the peeled waste edge film 504.

The motion tail end refers to a specific terminal motion executing part, and the motion tail end of the main motion supporting seat refers to a part capable of realizing horizontal and vertical motion, namely, the micro-motion mechanism at the motion tail end of the main motion supporting seat can realize horizontal and vertical motion through the driving part of the main motion supporting seat. Similarly, the micro-motion mechanism can drive the stripping component to move horizontally and vertically.

The horizontal motion on the main motion supporting seat of this embodiment includes single X axle horizontal motion, and the horizontal motion among the fine motion mechanism contains X axle horizontal motion, and main motion supporting seat is used for realizing the big step motion of X axle, and fine motion mechanism is then used for realizing the fine setting action of X axle, avoids great inertia to influence.

Specifically, the main motion supporting seat mainly comprises a base 110, an X-axis driving mechanism 111 and a Z-axis main driving mechanism 130, the base 110 serves as a mounting support of the whole device, the X-axis driving mechanism 111 is fixed on the base 110, an X-axis sliding seat 112 is arranged in cooperation with the X-axis driving mechanism 111, the Z-axis main driving mechanism 130 is mounted on the X-axis sliding seat 112, and a base 131 is connected with a lifting component of the Z-axis main driving mechanism 130, so that the base 131 can move in the vertical direction and the horizontal direction.

In another embodiment, the Z-axis main drive mechanism 130 may be connected to the base, the X-axis drive mechanism 111 may be provided on the elevating member of the Z-axis main drive mechanism 130, and the base 131 may be connected to the X-axis slide 112. The main motion supporting seat mainly aims at providing large-step motion, and the structural form of the main motion supporting seat is not particularly limited.

The micro-motion mechanism in this embodiment includes a film-removing driving mechanism 220 for controlling the horizontal motion and a Z-axis pair driving mechanism 210 for controlling the vertical motion, and the motion end of the micro-motion mechanism is located on the film-removing driving mechanism 220 or the Z-axis pair driving mechanism 210. The specific stripping component can adopt a conventional adsorption roller, and the film is stripped by the adsorption roller and then clamped by a clamping jaw mechanism so as to be removed.

Based on the structure of the embodiment, the method for removing the film by stripping comprises the following processes: the main motion support seat is used for providing large-step motion, namely the micro-motion mechanism is controlled to move in the horizontal direction through the X-axis driving mechanism 111, the micro-motion mechanism is controlled to move in the vertical direction through the Z-axis main driving mechanism 130, the micro-motion mechanism moves integrally at the moment, and the large-step motion is used for driving the micro-motion mechanism to move relative to the workbench 410 so as to adjust the position. The stripping component is driven by a micro-motion mechanism to move in the vertical and horizontal directions, so that the waste edge film 504 to be stripped on the display screen 500 is stripped to form an arched arc shape; the lifted scrap film 504 stripped by the stripping member is then gripped and removed by the gripper mechanism 320. The large step motion is relative to the micro-motion mechanism, and the motion range of the micro-motion mechanism at least in the horizontal direction is larger, so that the micro-motion mechanism can be used for removing the peeled film. And the bearing mass of the motion tail end of the micro-motion mechanism is necessarily smaller than that of the motion tail end of the main motion supporting seat, so that the inertia of the stripping part driven by the micro-motion mechanism is smaller, and the stability is better.

Example 2

In this embodiment, the horizontal movement of the main movement support base further includes a Y-axis movement, and the X-axis is perpendicular to the Y-axis. Specifically, referring to fig. 3, the X-axis driving mechanism 111 is fixed on the base 110, the Y-axis driving mechanism 120 is mounted on the X-axis sliding base 112, and the slide rail direction of the Y-axis driving mechanism 120 is perpendicular to the slide rail direction of the X-axis driving mechanism 111 and parallel to the worktable 410, and the slide rail of the Z-axis main driving mechanism 130 is perpendicular to the worktable 410.

In this embodiment, the X-axis driving mechanism 111, the Y-axis driving mechanism 120, and the Z-axis main driving mechanism 130 form a three-axis large-step motion assembly including two horizontal motion mechanisms and one vertical motion mechanism with respect to the work table, and the Z-axis sub-driving mechanism 210 and the film-drawing driving mechanism 220 form two small-inertia peeling assemblies including up-and-down motion and horizontal motion with respect to the work table, and are mainly used for fine-tuning the distance and position at the time of peeling.

Example 3

With reference to fig. 4, on the basis of embodiment 2, in this embodiment, a peeling knife 310 is used as a peeling component, and the peeling knife 310 may have a round rod structure, a square rod structure, a thin plate structure, or the like, and the lower end thereof is a pointed end, so as to facilitate puncturing into the membrane body. The film lifting driving mechanism 220 and the clamping jaw mechanism 320 are both arranged on the base 131, a horizontal sliding seat 230 capable of moving horizontally is arranged in the film lifting driving mechanism 220, and a stripping knife 310 is arranged on the horizontal sliding seat 230 and used for arching the waste edge film 504 to be stripped; the gripper mechanism 320 is used to grip the arched waste-edge film 504.

As other embodiments, the peeling element 310 may have other blade structure, such as two tips arranged in parallel at the bottom of the peeling element, and the parallel direction of the two tips may be the same as or perpendicular to the moving direction of the peeling element during peeling operation. The upper section of the peeling member 310 may have a rod-like or plate-like structure or the like, and the main purpose is to pierce the waste film with the tip of the lower end, and the connecting portion of the peeling member 310 is not particularly limited.

Specifically, the base 131 serves as a mounting base, which may be coupled to different portions of a particular user device, and through which different movements may be achieved by the mounting device. For example, by connecting the base 131 to the lifting mechanism, the entire peeling mechanism can be lifted and lowered; the base 131 is connected to a horizontally moving driving device, so that the entire micro-motion mechanism can horizontally move, and the micro-motion mechanism serves as a motion end of the main motion support base.

The film-lifting driving mechanism 220 may adopt a linear motor slide rail or a screw rod slide rail, for example, the screw rod slide rail is adopted, and the film-lifting driving mechanism 220 may specifically include a driving motor, a transmission screw rod and a guide rail, and the transmission screw rod is horizontally arranged. The horizontal sliding base 230 is provided with a screw rod pair, and is matched with the transmission screw rod and the guide rail, so that the horizontal sliding base 230 can be driven by the driving motor to horizontally move along the screw rod direction.

Further, a tool holder 311 is installed on the horizontal sliding base 230, a vertically arranged stripping knife 310 is installed on the tool holder 311, and the bottom end of the stripping knife 310 can be set as a tip end for pricking in the waste edge film 504 to be stripped. Since the peeling blade 310 and the blade holder 311 are generally fixedly mounted, in order to facilitate fixing, a blade holder mounting plate 312 may be disposed between the blade holder 311 and the horizontal slide 230, so as to mount the peeling blade 310.

The clamping jaw mechanism 320 in this embodiment includes a connecting arm 322, a clamping jaw driving mechanism 321, and a clamp body 323, where the clamping jaw driving mechanism 321 is used to control the clamp body 323 to open and close, and may adopt a hydraulic, pneumatic, or electric driving structure, and preferably, may adopt an electric clamping jaw driving mechanism. The clamp body 323 consists of two clamps, and the clamp body 323 can be controlled to close the clamped object through a clamping jaw driving mechanism.

The jaw driving mechanism 321 is connected to the base 131 via a connecting arm 322, so that the jaw driving mechanism 321 does not move relative to the base 131. And the peeling blade 310 can be horizontally moved with respect to the clamp body 323.

It should be noted that, since the peeling blade 310 can only move horizontally with respect to the clip body 323, in order to insert the peeling blade 310 into the waste edge film 504, the lower end of the peeling blade 310 needs to protrude from the bottom surface of the clip body 323 by a distance smaller than the thickness of the waste edge film 504.

When the film peeling device is used, the driving base 131 descends, the peeling blade 310 pierces the waste edge film 504 when the clamp 323 presses the upper protective film 503, and with reference to fig. 5, the peeling blade 310 is driven by the film lifting driving mechanism 220 to move toward the clamp 323, so that the waste edge film 504 is separated from the upper protective film 503 and arched, the waste edge film 504 can be clamped by driving the clamp 323, and the waste edge film 504 can be torn off by moving the base 131 or the lower stage.

Fig. 6 provides a specific mounting position of the Z-axis pair driving mechanism 210, in this embodiment, the Z-axis pair driving mechanism 210 is fixed on the base 131, the lifting plate 211 is provided in the Z-axis pair driving mechanism 210, and the film lifting driving mechanism 220 is mounted on the lifting plate 211 for moving the peeling blade 310 up and down relative to the gripper mechanism 320.

The Z-axis pair driving mechanism 210 may adopt driving manners of different forms and different structures, and its main purpose is to ensure that the lifting plate 211 can move up and down, for example, a linear motor guide rail may be adopted to drive the lifting plate 211 to move up and down. The elevating plate 211 can move up and down by the power of the Z-axis pair driving mechanism 210.

The peeling blade 310 can be driven to move up and down by the Z-axis pair driving mechanism 210 by attaching the film lifting driving mechanism 220 to the lifting plate 211. By matching the film lifting drive mechanism 220 with the Z-axis pair drive mechanism 210, the up-and-down movement and the horizontal movement of the peeling knife 310 can be realized.

Example 5

Referring to fig. 7, the apparatus for peeling and removing a thin film of the present embodiment further includes a distance measuring device 330, wherein the distance measuring device 330 moves synchronously with the peeling blade 310. The distance measuring device 330 is used to detect the height from the waste film 504 before peeling, and an optical distance measuring device, such as a laser distance measuring device, may be used.

When the device is used, the distance measuring device 330 is moved to the lower knife position, then the required downward movement distance of the stripping knife 310 is detected, then the stripping knife 310 is moved to the lower knife position, and then the stripping knife 310 is pricked into the waste edge film 504 by matching with the base 131 and the Z-axis pair driving mechanism 210. The peeling blade 310 is driven by the film raising driving mechanism 220 to move forward slowly for a certain distance, so that the waste edge film 504 is arched to form a semicircular arc shape and then stops, the arched waste edge film 504 can be clamped by the clamp body 323, and then the peeling operation can be carried out.

Example 6

Fig. 7 also shows an embodiment of the film-drawing driving mechanism 220. In this embodiment, the film-drawing driving mechanism 220 further comprises a servo motor 221, a transmission belt 222 and a shield 223, the servo motor 221 is fixed on the lifting plate 211 and is located above the lifting plate 211, the guide rail and the lead screw in the film-drawing driving mechanism 220 are mounted on the lifting plate and are located at the middle-lower position, and transmission is performed between the lead screw and the servo motor 221 through the transmission belt 222. Further, a shield 223 is covered on the outer side of the belt 222 for safety protection.

Fig. 8 shows a state where the peeling blade 310 is positioned when piercing the waste-edge film 504; fig. 9 shows the state that the waste edge film 504 is arched in an arc shape by the peeling knife 310, and the operation principle of the peeling mechanism can be clearly shown by two structural changes.

Example 7

Referring to fig. 10, the embodiment can also realize the horizontal movement and the vertical movement of the peeling knife 310, except that in the embodiment, the positions of the film-removing driving mechanism 220 and the Z-axis secondary driving mechanism 210 are exchanged, the film-removing driving mechanism 220 is fixedly mounted on the base 131, the Z-axis primary driving mechanism 130 is mounted on the horizontal sliding base 230, and the film-removing driving mechanism 220 can drive the Z-axis primary driving mechanism 130 to horizontally move in the same direction.

The Z-axis pair driving mechanism 210 is provided with a lifting plate 211, and the stripping knife 310 is fixedly mounted on the lifting plate 211, that is, the knife holder 311 of the stripping knife 310 is mounted on the lifting plate 211, or the knife holder 311 is connected with the lifting plate 211 through a knife holder mounting plate 312.

In this embodiment, although the structural form is changed, the horizontal movement and the vertical movement of the peeling blade 310 can be realized, and the peeling work can be normally performed.

Example 8

On the basis of the above embodiment, with reference to fig. 8 and 9, as a preferred embodiment, an interlayer pad 324 may be disposed on the clamping surface of the clamp body 323. The interlayer pad 324 may be made of rubber, which is beneficial to protect the display screen 500 and prevent the display screen 500 from being damaged during the operation of the clip body.

Example 9

In addition to embodiment 8, in this embodiment, the interlayer pad 324 protrudes from the bottom surface of the clip body 323, or a gasket is disposed on the bottom surface of the clip body 323, and the gasket and the interlayer pad 324 may be made of rubber, or may be made of other soft materials, which is not particularly limited.

In addition, in the scheme that the stripping knife is parallel to the clamping surface, the clamp body positioned above the upper protective film 503 can press the upper protective film 503, so that the upper protective film 503 at the edge part cannot be lifted when the waste edge film 504 is stripped, and the phenomenon that the upper protective film 503 is folded is avoided. This protective effect can be further optimized when using an interlayer gasket 324 or shim.

As a modification, the bottom surfaces of the two clips of the clip body 323 may be arranged not to be in the same plane, wherein the clip in contact with the upper protective film 503 is in a lower position, the other clip is mainly used for the waste edge film clipping, and the bottom surface position may be relatively high. When the clamp is used specifically, the clamp can press the upper protective film, or the clamp and the upper protective film are not contacted, and no specific requirement exists.

Example 10

In the above embodiment, the clamping surface of the clamp body 323 is parallel to the horizontal movement direction of the peeling blade 310, and alternatively, the horizontal movement direction of the peeling blade 310 may be perpendicular to the clamping surface of the clamp body 323.

Fig. 11 shows an embodiment in which the direction of movement of the peeling blade 310 is perpendicular to the holding surface, and in this case, since the waste-edge film 504 is arched and held in the width direction, the clamp body 323 holds only a partial region of the waste-edge film 504.

It should be noted that, in this embodiment, if the clip 323 still presses the upper protective film 503, the waste edge film 504 is also pressed, and the peeling blade cannot raise the waste edge film 504, so that the clip can be suspended above the upper protective film 503.

Referring to fig. 12, as a modification, the clips 323 may be positioned near the end portions of the waste film 504 where one clip is positioned at the outer end of the waste film 504 without contacting the waste film 504 and the other clip may press down the waste film 504, in this embodiment, it is easier to arch the waste film 504 since the waste film 504 is peeled off at a fixed length.

Example 11

In the embodiment, the clip body 323 is further improved to solve the problem that the waste edge film 504 is pressed and cannot be arched in the embodiment 10.

As shown in fig. 13, in this embodiment, the bottom surface of the clip 323 has a step surface, the lowest surface can press the upper protective film 503, and the position of the clip opposite to the waste edge film 504 forms a gap due to the step surface, so that the waste edge film 504 can be lifted up by the peeling blade.

In practice, only one of the clamp bodies 323 may be provided with a stepped surface, for example, depending on the position of the clamp body.

Example 12

In the film peeling and removing apparatus of the present embodiment, a worktable 410 is disposed below the base 131 of the apparatus for carrying the display screen 500. More specifically, the stage is located below the peeling mechanism so that the peeling mechanism can move above. The stage 410 may be a stage having adsorption holes, for example, a porous ceramic stage or a metal microporous adsorption plate.

During processing, one side of the display screen 500 with the waste edge film 504 can be arranged close to the edge, and the waste edge film 504 can be quickly removed after being peeled off. Preferably, a waste bin 430 may be provided at one side of the table 410 for receiving the stripped waste mold.

Example 13

The film peeling and removing device of the embodiment further includes a lifting platform 420, the lifting platform 420 is located on one side of the working platform 410 and combined with the working platform 410 to form a processing platform, and during processing, the waste edge film 504 is located above the lifting platform 420.

The lifting platform 420 can be an electric lifting platform or a hydraulic lifting platform or a pneumatic lifting platform, i.e. the lifting platform is driven to move up and down by a corresponding power system. The elevating platform 420 is used as an auxiliary support, can be descended when not needed, can reduce the area of the worktable, and can prevent interference with other components. For example, after peeling off the waste edge film, the lift table 420 may be lowered and the table 410 moved to the next station.

In this embodiment, the motion scheme of the thin film peeling and removing method is as follows:

after the small flexible display screen 500 is placed on the worktable 410, the lifting platform 420 is lifted to be coplanar with the worktable 410, and then the worktable 410 adsorbs the display screen 500. The X-axis driving mechanism 111 and the Y-axis driving mechanism 120 move in a large step distance manner to drive the distance measuring sensor 8 to the position where the slitter edge film 504 descends, and the distance measuring sensor 8 measures the height of the cutter head required to descend. The X-axis driving mechanism 111 and the Y-axis driving mechanism 120 drive the peeling knife 310 to the lower knife position, then the Z-axis main driving mechanism 130 continues to descend, and the lower edge of one clip of the clip body 323 stops after touching the display screen 500.

The Z-axis pair driving mechanism 210 drives the peeling blade 310 to gradually descend and pierce into the upper protective film 503 of the display screen 500. Then the film lifting driving mechanism 220 drives the peeling knife 310 to slowly advance for a short distance along the peeling direction, the to-be-removed clamp body 323 on the display screen 500 is peeled and arched, the to-be-removed clamp body 323 stops after being arched to form a semicircular arc shape, and the arched to-be-removed clamp body 323 is clamped by the clamp body 323. The Z-axis main driving mechanism 130 drives the clamp 323 to stop after rising for a certain distance, the X-axis driving mechanism 111 and the Y-axis driving mechanism 120 drive the clamp 323 to completely strip and remove the waste edge film 504 to be removed from the display screen 500 and move to the position above the waste bin 430, and the clamp 323 is loosened to put the stripped and removed waste edge film 504 into the waste bin 430. And finally, automatically resetting each driving shaft of the stripping and removing mechanism to wait for the next action cycle.

The device has small inertia of the stripping part and adopts a micro-motion mechanism, so that the high-precision stable operation can be realized at the initial stage of stripping the waste edge film. After the waste edge film is arched, the waste edge film can be reliably clamped and peeled. Therefore, the stripping device adopting the stripping mechanism can stably strip and remove the waste edge film, cannot generate wrinkles and bubbles, cannot damage the functional layer, and is favorable for improving the product quality and the qualification rate.

The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
