As in the background art, in the process of manufacturing a flexible OLED display product, a heat dissipation film or other film material needs to be attached to a cover plate. In the related art, a roller is generally used to press the heat dissipation film to be attached to the cover plate. Although the method has strong compatibility and can be suitable for the special-shaped cover plates with various shapes, a special-shaped cover plate database needs to be established in a program, and shape data of various different special-shaped cover plates are stored in the special-shaped cover plate database. When the roller is attached, the program can control the roller according to the shape data of the selected special-shaped cover plate. Before the attachment, matched special-shaped cover plate shape data are selected from a cover plate database according to the shape of the special-shaped cover plate to be attached, a program loads a corresponding control instruction into the attachment equipment according to a selection result, the selection process of the special-shaped cover plate shape data and the loading and debugging process of the control instruction are complex, and more working hours are occupied.

In order to retain the advantage of the strong compatibility of the roller attaching method and simplify the program debugging process before attaching, as shown in fig. 1, 2, and 12, an embodiment of the present application provides an attaching apparatus, including a scanning unit 1, configured to obtain a shape parameter 13 of a first film material 4 to be attached; the control unit 2 is connected with the scanning unit 1 and used for generating a control instruction according to the shape parameters 13; and the roller unit 3 is connected with the control unit 2 and used for pressing the second film material 5 to be attached along the shape of the first film material 4 to be attached according to a control instruction, so that the second film material 5 to be attached is attached to the first film material 4 to be attached.

Before the bonding is started, the first film material 4 to be bonded may be fixed, and the first film material 4 to be bonded may be a hard film material such as a glass cover plate, which has a specific shape before being fixed, and the specific shape may be a C-shape (as shown in fig. 3 a), an L-shape (as shown in fig. 3 b), an S-shape (as shown in fig. 3C), or the like. The surface to be bonded of the first film material 4 to be bonded can be a convex arc surface or a concave arc surface. The first film material 4 to be attached may also be a flexible film material, which has a specific shape according to the shape of the jig after being fixed.

In order to replace the process of manually inputting the shape of the first film material 4 to be attached, the shape parameter 13 of the first film material 4 to be attached is automatically collected by the scanning unit 1. For example, the shape parameter 13 may be a radius of curvature of the first film material to be laminated 4, position information of a plurality of points on the first film material to be laminated 4, or the like. The control unit 2 can restore the shape of the first film material 4 to be laminated according to the shape parameter 13, and generates a control command after analysis. After that, the control unit 2 sends a control instruction to the wheel unit 3. The roller unit 3 is located on one side, away from the first film material 4 to be laminated, of the second film material 5 to be laminated, and after receiving the control instruction, the roller unit 3 moves from a lamination starting position 9 (namely, the position where the first film material 4 to be laminated and the second film material 5 to be laminated are firstly laminated to each other) to a lamination ending position 10 (namely, the position where the first film material 4 to be laminated and the second film material 5 to be laminated are finally laminated to each other) along the shape of the first film material 4 to be laminated, and presses the second film material 5 to be laminated simultaneously so as to be gradually laminated with the first film material 4 to be laminated.

The laminating equipment that this embodiment provided, through scanning unit 1 automatic acquisition first waiting to laminate membrane material 4's shape parameter 13, can enough save the process of manual input and selection debugging procedure, simultaneously, because scanning unit 1 is at the during operation, first waiting to laminate membrane material 4 has accomplished fixedly, the shape parameter 13 that scanning unit 1 obtained corresponds first waiting to laminate membrane material 4 at the actual shape of laminating in-process promptly, consequently the laminating equipment of this embodiment is all lower to the product uniformity requirement and the fixed position required precision of first waiting to laminate membrane material 4. The laminating equipment of this embodiment still generates control command through the control unit 2 to control roller unit 3 moves to laminating termination point 10 by laminating initial position 9 along the first shape of waiting to laminate membrane material 4, and the second is waited to laminate membrane material 5 simultaneously to make it laminate gradually with first membrane material 4 that waits to laminate, and guarantee in the laminating in-process, the second is waited to laminate the pressing force that membrane material 5 received evenly, guarantees the laminating quality.

In the laminating apparatus of the present embodiment, since the control of the roller unit 3 depends on the acquired shape parameter 13 of the first film material to be laminated 4, it is necessary to reduce the difference as much as possible between the shape of the first film material to be laminated 4 restored by the control unit 2 according to the shape parameter 13 and the actual shape of the first film material to be laminated 4 after the fixing is completed. In order to achieve the above purpose, as shown in fig. 1, fig. 2 and fig. 4, in some embodiments, the scanning unit 1 includes a distance meter 11 facing the first film material 4 to be laminated, and a scanning driving device 12 for driving the distance meter 11 to move along a first direction; the distance measuring instrument 11 is used for acquiring projection distances between a plurality of detection points of the first film material 4 to be laminated and the distance measuring instrument 11 in the moving process as shape parameters 13; the first direction is a direction from the bonding start position 9 to the bonding end position 10.

As will be exemplarily explained below with the structures in fig. 2, 11, and 12, the scanning unit 1 is disposed above the first film material to be laminated 4. The scanning unit 1 moves from the attaching start position 9 to the attaching end position 10 in the process of acquiring the shape parameter 13 of the first film material 4 to be attached, the scanning unit 1 passes through a plurality of detection points on the first film material 4 to be attached in the moving process, when the scanning unit 1 moves to a position right above one detection point, the distance between the distance meter 11 and the detection point is the projection distance, the distance meter 11 detects the projection distance between the distance meter 11 and the detection point, and the detected projection distance is sent to the control unit 2 as the shape parameter 13.

Optionally, the distance meter 11 may be one or more laser distance meters, the sensitivity of each laser distance meter may reach ± 0.3 μm, the measurement stroke is 0 to 100mm, and the method is applicable to the first to-be-bonded film 4 of all shapes with a step difference of less than 100 mm.

In addition, in order to improve the movement stability of the scanning unit 1, as shown in fig. 1 and 2, the attaching device of the present embodiment may further include a set of slide rails 6 disposed above the scanning unit 1. The scanning driving device 12 is mounted on the slide rail 6 and can move at a constant speed along the slide rail 6 at a preset speed to drive the distance measuring instrument 11 to complete the scanning operation of the first film material 4 to be attached. Of course, in order to adjust the distance between the distance meter 11 and the first film material 4 to be attached, the scanning driving device 12 may further implement a telescopic function through an electric cylinder or the like, so as to drive the distance meter 11 to be close to or far away from the first film material 4 to be attached.

However, the distance between the distance meter 11 and the first film material to be laminated 4 can be adjusted only before or after the scanning is performed. During the scanning process, i.e., during the movement of the distance meter 11 from the application start position 9 to the application end position 10, the distance between the distance meter 11 and the first film material 4 to be applied remains constant. For example, as shown in fig. 11, when the first film material 4 to be bonded is horizontally placed, the distance meter 11 is horizontally moved from the bonding start position 9 to the bonding end position 10 by the scanning driving device 12.

In general, when the first film material 4 to be bonded is fixed, it is necessary that the levelness in the second direction (e.g., the Y direction in fig. 1 and 4) reaches a preset requirement. Therefore, in order to check the levelness of the first film material to be laminated 4, as shown in fig. 4, in some embodiments, the distance meters 11 are provided in three and are uniformly distributed along a second direction perpendicular to the first direction. The three distance measuring instruments 11 are uniformly distributed along the second direction and respectively correspond to two side positions and a middle position of the first film material 4 to be laminated, and when the levelness of the first film material 4 to be laminated in the second direction is an ideal state, the measurement readings of the three distance measuring instruments 11 should be the same. If the measurement readings of the three distance meters 11 are different and the difference between the values exceeds 0.3mm, it is indicated that the levelness of the first film material 4 to be attached in the second direction cannot meet the preset requirement. At this moment, the laminating device of this embodiment can report to the police through modes such as reputation, reminds operating personnel to fix first membrane material 4 that need to laminate again.

After the scanning unit 1 sends the acquired projection distances corresponding to the plurality of detection points to the control unit 2, in some embodiments, the control unit 2 is further configured to determine the positions of the corresponding detection points according to the plurality of projection distances and fit to form a profiling curve matched with the shape of the first film material 4 to be attached; the control commands are generated according to the profile curve.

Since the scanning unit 1 moves at a constant speed along the first direction at a predetermined speed, the real-time position of the distance meter 11 is known during the moving process, and the position of each detection point on the surface of the first film material 4 to be laminated can be obtained by combining the position with the corresponding projection distance obtained by detection. The control unit 2 can fit the detection points with the determined positions to form a profiling curve matched with the shape of the first film material to be laminated 4, and since the detection points are all located on the first film material to be laminated 4, the positions of the detection points can represent the actual position of the first film material to be laminated 4, and the more the detection points are arranged, the closer the shape of the profiling curve passing through all the detection points is to the actual shape of the first film material to be laminated 4. After the profiling curve is formed, the control unit 2 generates a control command for controlling the movement of each functional unit such as the roller unit 3 according to the profiling curve.

Illustratively, as shown in fig. 5 and 12, in some embodiments, the roller unit 3 includes a roller 31 for pressing the second film 5 to be laminated and a roller driving device 32 rotatably connected to the roller 31; the control commands include a roller control command 21, and the roller driving device 32 is configured to drive the roller 31 to move according to the roller control command 21.

Optionally, the roller driving device 32 is also mounted on the slide rail 6, and the roller driving device 32 has two motion forms of moving along the slide rail 6 and extending and retracting along a direction perpendicular to the slide rail 6, and can drive the roller 31 to move along a first direction (e.g., an X direction in fig. 2) and a third direction (e.g., a Z direction in fig. 2), and the movement in the two directions is controlled by the roller control instruction 21, respectively, and the movement in the two directions can be matched with each other, so that a track of the roller 31 moving from the bonding start position 9 to the bonding end position 10 matches with the shape of the first film material 4 to be bonded.

The roller control command 21 is a control command that the control unit 2 needs to generate for the movement of the roller 31, and the roller control command 21 is generated as follows, for example:

as shown in fig. 14, the control unit 2 may first divide the profile curve into a plurality of sections (or referred to as cells) according to the moving accuracy of the roller driving device 32 or the preset distance f along the first direction, where each section includes a section of the profile curve, and the positions of two end points of the section of the profile curve are shown as a point a and a point B in fig. 14. When the height difference between the point a and the point B is less than or equal to the movement accuracy of the roller unit 3, a straight line connecting the point a and the point B may be used as the movement locus of the roller unit 3 in the interval. For example, the minimum motion precision of the roller unit 3 is 0.2mm, and when the height difference c between the point a and the point B is less than or equal to 0.2mm, the point a and the point B are connected by a straight line, which is the motion track of the roller unit 3 in the interval.

When the height difference between the point a and the point B is larger than the movement accuracy of the roller unit 3, an intermediate point is set between the point a and the point B, and the point a is connected to the point B through a multi-segment line as the movement locus of the roller unit 3 in the interval.

And connecting the obtained moving tracks in all the intervals end to end, namely obtaining the moving track of the roller unit 3 from the attaching starting position 9 to the attaching ending position 10. The control unit 2 analyzes the moving track to generate the roller control command 21 for controlling the roller driving device 32 to move along the first direction and the third direction.

Before the bonding is started, the second film material 5 to be bonded needs to be positioned on one side of the first film material 4 to be bonded, for example, as shown in fig. 1, 6 and 7, the bonding apparatus of the embodiment further includes an upper base station unit 7 which is arranged at an interval on one side of the roller unit 3 close to the bonding termination position 10 and includes an upper positioning surface 711 for positioning the second film material 5 to be bonded; the upper base station unit 7 is connected with the control unit 2; the control instruction comprises an upper base station control instruction 22, the upper base station unit 7 is used for moving along the first direction according to the upper base station control instruction 22, and in the moving process, the second film material 5 to be attached can be moved out of the upper positioning surface 711 and is pressed and attached to the first film material 4 to be attached through the roller unit 3.

For example, the second film material to be laminated 5 is positioned above the first film material to be laminated 4. In the process of attaching, the upper base station unit 7 drives the second film material 5 to be attached to move to the attachment starting position 9, and the one end of the second film material 5 to be attached and the one end of the first film material 4 to be attached are attached to each other at the attachment starting position 9 first. Then, the upper base unit 7 moves to the bonding ending position 10, as shown in fig. 13, but since a part of the second film 5 to be bonded is bonded to the fixed first film 4 to be bonded, the second film 5 to be bonded gradually moves out of the upper positioning surface 711 along with the movement of the upper base unit 7, and the second film 5 to be bonded has a certain gap with the first film 4 to be bonded at the moment of moving out of the upper positioning surface 711, that is, the two films are not bonded at this time. Subsequently, the roller unit 3 presses the second film 5 to be attached that has moved out of the upper positioning surface 711, so that the second film 5 to be attached moves toward the first film 4 to be attached until the two are attached to each other. The process of attaching the first film material 4 to be attached and the second film material 5 to be attached is a process of continuously moving the second film material 5 to be attached out of the upper positioning surface 711 and pressing the second film material to be attached to the first film material 4 to be attached by the roller unit 3.

In order to ensure that the second film 5 to be bonded gradually moves out of the upper positioning surface 711 rather than directly falls off from the upper positioning surface 711 during the bonding process, the upper positioning surface 711 needs to be turned over according to the undulation shape of the first film 4 to be bonded. To accomplish the flipping of the upper positioning surface 711, as shown in fig. 6, 7 and 12, for example, in some embodiments, the upper base unit 7 includes a loading plate 71 provided with the upper positioning surface 711, a first driving device 72 rotatably connected to one side of the loading plate 71 in a first direction, and a second driving device 73 rotatably connected to the other side of the loading plate 71; the upper base control command 22 includes a first upper base command 221 and a second upper base command 222, the first driving device 72 drives the bearing plate 71 to approach or separate from the first film material 4 to be bonded according to the first upper base command 221 and the second driving device 73 drives the bearing plate 71 to approach or separate from the first film material 4 to be bonded according to the second upper base command 222, so that the bearing plate 71 maintains a predetermined relative position with the first film material 4 to be bonded in the process of moving along the first direction.

The upper base station control command 22 is a control command that the control unit 2 needs to generate according to the movement of the upper positioning surface 711, and the upper base station unit 7 makes the upper positioning surface 711 maintain a preset relative position with the first film material 4 to be bonded in the process of moving from the bonding start position 9 to the bonding end position 10 according to the upper base station control command 22. Illustratively, the first film material 4 to be attached protrudes toward the second film material 5 to be attached, and in the moving process of the upper positioning surface 711 along the first direction, the straight line of the edge of the upper positioning surface 711 close to the attachment starting position 9 and the straight line of the contact position of the roller unit 3 and the second film material 5 to be attached are located, and the same plane where the two straight lines are located needs to be tangent to the first film material 4 to be attached.

Taking fig. 15 as an example, a curve in the figure is a profile curve of the first film material to be laminated 4, and the control unit 2 determines a movement locus of the upper positioning surface 711 along the first direction according to the profile curve. The upper positioning surface 711 needs a straight line (indicated by a point d in the drawing because the axial direction of the straight line is the Y direction) on which the edge near the sticking start position 9 is located and a straight line (indicated by a point e in the drawing because the axial direction of the straight line is the Y direction) on which the roller 31 of the roller unit 3 presses the second film material 5 to be stuck in the moving process from the sticking start position 9 to the sticking end position 10, and the same plane (a connecting line between the point d and the point e, i.e., a dashed-dotted line in fig. 15) on which the two straight lines are located is tangent to the first film material 4 to be stuck (i.e., a curve in the drawing).

It can be seen that the upper positioning surface 711 is continuously turned over during the moving process along the first direction, which requires that the stretching amount of the first driving device 72 and the stretching amount of the second driving device 73 are not synchronized, so that the control unit 2 analyzes the motion track of the upper positioning surface 711 along the first direction again to split the upper base control command 22 into the first upper base command 221 and the second upper base command 222, and the first upper base command 221 is sent to the first driving device 72, which controls the first driving device 72 to move along the first direction and drives the side of the supporting plate 71 close to the bonding start position 9 to be close to or far from the first film material 4 to be bonded through stretching during the moving process. And the second upper base instruction 222 is sent to the second driving device 73, which controls the second driving device 73 to move along the first direction and drives the side of the bearing plate 71 close to the attaching termination position 10 to be close to or far from the first film material 4 to be attached by telescoping in the moving process. The first driving device 72 and the second driving device 73 move independently to drive the carrier plate 71 to turn over, so that the upper positioning surface 711 maintains a preset relative position with the first film 4 to be laminated during the movement along the first direction.

Alternatively, the first driving device 72 and the second driving device 73 are both connected to the bearing plate 71 via a rotation shaft and connected to the sliding rail 6, similar to the roller driving device 32.

In the attaching process, the moving track of the roller unit 3 is actually a curved track formed by fitting a plurality of short straight-line tracks due to the limitation of the motion precision of the roller unit. In other words, the actual moving track of the roller 31 of the roller unit 3 does not completely match the shape of the first film material to be bonded 4, so that the stress applied to the second film material to be bonded 5 in the process of moving and pressing the second film material to be bonded 5 toward the first film material to be bonded 4 of the roller unit 3 has large stress non-uniformity and a fracture risk, and therefore, the unit for fixing the first film material to be bonded 4 needs to have a certain buffering function.

In order to achieve the above functions, as shown in fig. 8 and 9, the attaching device of the present embodiment further includes a lower base unit 8, which includes a substrate 81 and a fixing jig 82 disposed above the substrate 81, and elastic support structures 83 are uniformly disposed between the substrate 81 and the fixing jig 82; the fixing jig 82 includes a profiling surface 821 for fixing the first film 4 to be attached, and the profiling surface 821 matches with the shape of the first film 4 to be attached.

In order to fix the first film material 4 to be laminated and avoid the movement thereof in the laminating process, optionally, the fixing jig 82 is further provided with a plurality of through holes penetrating through to the contour surface 821, the through holes are communicated with the negative pressure device, and the fixing jig 82 provides negative pressure adsorption through the through holes to fix the first film material 4 to be laminated. The plurality of through holes may be uniformly arranged on the contoured surface 821, and the specific number, size and shape of the through holes may be set according to the requirement, and are not limited in particular. The through hole passes through the fixing jig 82 to form an air passage communicated with the negative pressure device. When the first to-be-bonded film 4 on the mold surface 821 needs to be fixed, the negative pressure device generates negative pressure on one side of the first to-be-bonded film 4, which is close to the mold surface 821, through the air passage formed by the through hole, and the first to-be-bonded film 4 is tightly bonded to the mold surface 821 under the action of air pressure on the other side of the first to-be-bonded film 4.

In addition, when the pressing force that roller unit 3 produced is too big to laminating first membrane material 4 and the second membrane material 5 of waiting to laminate, elastic support structure 83 can take place elastic deformation in order to subduct too big pressing force, reaches the buffering purpose, realizes waiting to laminate the protection of membrane material 5 to first membrane material 4 and the second of waiting to laminate. For the elastic support structure 83, an elastic material layer with a uniform thickness may be selected, or a plurality of individual elastic members may be uniformly disposed between the substrate 81 and the fixing jig 82. For example, twenty-five longitudinal rigid springs are arranged between the substrate 81 and the fixing jig 82, the twenty-five springs are arranged in a 5 × 5 manner, the elastic coefficient and the compression stroke amount of each spring are the same, for example, the elastic coefficient of each spring is 2000N/mm, so that the uniformity of the overall levelness of the fixing jig 82 can be ensured, and the uniformity of the pressing force applied to the first film material to be attached 4 and the second film material to be attached 5 in the attaching process can also be ensured.

Based on the same inventive concept and in combination with the description of the laminating apparatuses in the above embodiments, this embodiment provides a film laminating method, which has the corresponding technical effects of the laminating apparatuses in the above embodiments, and is not described herein again.

As shown in fig. 16, a film material attaching method using the attaching apparatus of each of the above embodiments includes:

in step S101, the scanning unit 1 acquires the shape parameter 13 of the first film material 4 to be bonded.

In step S102, the control unit 2 generates a control command based on the shape parameter 13.

Step S103, the roller unit 3 presses the second film material to be bonded 5 along the shape of the first film material to be bonded 4 according to the control instruction, so that the second film material to be bonded 5 is bonded to the first film material to be bonded 4.

The first film material 4 to be bonded is taken as a convex C-shaped cover plate, and the second film material 5 to be bonded is taken as a heat dissipation film, for example, the bonding process of the two is explained.

First, the cover plate is fixed to the mating surface 821 of the lower base unit 8, and the heat dissipation film is smoothly positioned on the upper positioning surface 711. At this time, the upper base unit 7 and the roller unit 3 move out of the space above the first film 4 to be bonded along the slide rail 6, and move to the standby position to provide a space for the movement of the scanning unit 1, as shown in fig. 10. At this time, the scanner unit 1 is located at an appropriate height above the bonding start position 9 for preparation of a work including program restoration, setting of the current position as the origin, and the like.

After the scanner unit 1 finishes the preparation, the distance measuring instrument 11 is turned on, and starts to move uniformly from the bonding start position 9 to the bonding end position 10 at a predetermined speed (e.g., 30 mm/s), as shown in fig. 11. The distance between each detection point on the cover plate and the distance meter 11 is acquired in real time by the distance meter 11 during the moving process as the shape parameter 13 of the cover plate. When the scanning unit 1 is moved to the position 10 where the sticking is terminated, the acquisition work thereof is completed. The scanning unit 1 moves out of the space above the first film material 4 to be laminated, and sends the acquired shape parameter 13 of the cover plate to the control unit 2 (optionally, the control unit 2 is an industrial personal computer), as shown in fig. 12. The control unit 2 processes the shape parameters 13 of the cover plate to obtain control instructions, where the control instructions include a roller control instruction 21, a first upper base instruction 221, and a second upper base instruction 222, and sends the roller control instruction 21 to the roller driving device 32 through a signal line, the first upper base instruction 221 to the first driving device 72, and the second upper base instruction 222 to the second driving device 73. Under the cooperation of the first driving device 72 and the second driving device 73, the loading plate 71 drives the heat dissipation film to approach the cover plate, so that one end of the heat dissipation film is attached to one end of the cover plate at the attachment start position 9. Thereafter, the carrier plate 71 is moved toward the attaching end position 10 and maintains a preset relative position with the cover plate by being turned over, as shown in fig. 13. The roller unit 3 moves synchronously with the upper base unit 7, and presses the heat dissipation film removed from the upper positioning surface 711, so that the heat dissipation film is stably attached to the surface of the cover plate.
