Description

Technical Field

[0001] This invention relates to a sheet separation device and a sheet separation method, particularly a device and method for easily separating sheets from an adsorption platform. The device and method have an adsorption platform above a lifting mechanism to attach the sheet to an adsorption layer, so that the top module of the lifting mechanism can rise and push the adsorption layer to achieve the purpose of separating the sheet from the adsorption layer. Background Technology

[0002] With the advent of the Internet of Things (IoT) and Industry 4.0, the number and applications of connected devices have increased dramatically. Moreover, the communication and interaction between these connected devices are mostly carried out automatically without human intervention. Therefore, more and more equipment will need to automatically coordinate with each other to complete specific overall manufacturing processes without human operation. However, in unmanned automated operation, the pass rate and accuracy of each workstation are very important to prevent low pass rate and accuracy from affecting the smoothness of operations or even causing downtime, which would delay the overall manufacturing process.

[0003] Furthermore, with the continuous research and development and improvement of LCD and touch panel manufacturing technologies, the next generation of product applications are all designed to be lighter, thinner, more energy-efficient, more flexible, or larger in size with curved surfaces. However, in the automated process of removing flexible panels (such as OLED or LCD displays) from the substrate, mechanical lift-off (MLO), laser lift-off (LLO), or laser lift-off with temporary adhesives can be used. Because mechanical lift-off has obvious advantages in equipment cost and process simplicity, most flexible panels use mechanical lift-off in the process of removing them from the substrate.

[0004] However, because the mechanical removal process removes the flexible panel from the substrate by mechanical peeling, the film of the flexible panel is prone to curling and deformation due to excessive release force, and it is also easy to damage the electronic components on the film, thus affecting the manufacturing yield. Therefore, a successful mechanical removal process must consider whether the film can maintain flatness and low deformation, and avoid damage to electronic components, so that the removal of the flexible panel can maintain a high yield and be ready for subsequent automated processes.

[0005] Therefore, how to solve the current problems and troubles of removing flexible panels from the substrate, and the troubles and defects such as curling and deformation of flexible panels, is the direction that relevant manufacturers in this industry are eager to research and improve. Summary of the Invention

[0006] Therefore, in view of the above-mentioned problems and deficiencies, the inventor collected relevant information, conducted multiple evaluations and considerations, and, based on years of experience accumulated in this industry, continuously created and modified the invention patent for this sheet separation device and sheet separation method.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A sheet separation device, characterized in that it includes an adsorption platform and a lifting mechanism, wherein:

[0009] The adsorption platform includes a base and an adsorption layer attached to the surface of the base. The base includes a frame-shaped body and a mesh plate located on the surface of the frame-shaped body. The adsorption layer is attached to the surface of the mesh plate, and a working space is formed on the other side of the mesh plate and inside the other side of the frame-shaped body.

[0010] The lifting mechanism is located below the working space of the base of the adsorption platform. It includes a top support module and a lifting module connected to the bottom of the top support module. The lifting module is used to drive the top support module to move longitudinally in and out of the working space of the frame body. The top support module includes a seat connected to the top of the lifting module, a shaft embedded in the seat, a first top support wheel assembled on the shaft, and at least one second top support wheel on each side of the first top support wheel. The lifting module drives the first top support wheel and each of the second top support wheels of the top support module to move longitudinally in and out of the working space of the frame body and to abut or retract from the bottom surface of the mesh plate.

[0011] The sheet separation device, wherein: the base of the adsorption platform includes a rectangular frame body, and the adsorption layer attached to the surface of the mesh plate on the rectangular frame body has a plurality of grooves arranged in an alternating pattern on its surface.

[0012] The sheet separation device, wherein: the lifting module of the lifting mechanism is a hydraulic cylinder or a pneumatic cylinder, and the lifting module is also connected to a lateral displacement module at the bottom, the lateral displacement module driving the lifting module to move horizontally back and forth below the adsorption platform.

[0013] The sheet separation device wherein: the top of the lifting mechanism is connected to the top of the base body, and positioning parts are respectively recessed on both sides of the top of the base body, and the shaft is provided at the two positioning parts of the base body.

[0014] The sheet separation device, wherein: the diameter of the first top support wheel assembled on the shaft of the top support module of the lifting mechanism is greater than the diameter of at least one second top support wheel on each side.

[0015] A sheet separation method of a sheet separation device includes an adsorption platform, a lifting mechanism, and a sheet located on an adsorption layer of the adsorption platform, characterized in that the separation method between the sheet and the adsorption layer is based on the following steps:

[0016] (A01) The lifting mechanism uses the lifting module to drive the top-supporting module to move to the working space at the bottom of the adsorption platform;

[0017] (A02) The top support module enters the working space, and the first top support wheel assembled on the shaft of the top support module first abuts against the bottom surface of the mesh plate of the adsorption platform;

[0018] (A03) At least one second top abutment wheel on each side of the first top abutment wheel on the shaft abuts against the bottom surface of the mesh plate of the adsorption platform;

[0019] (A04) The first top roller pushes the bottom surface of the mesh plate and then pushes the adsorption layer upward. At the position where the adsorption layer and the sheet are pushed, the adsorption layer is deformed and bent due to the force. This causes at least one groove on the adsorption layer opposite to the first top roller to have its internal air diffuse to the surrounding area to other grooves, and pushes the sheet upward, forming a gap between the adsorption layer and the sheet.

[0020] (A05) Separate the sheet from the adsorption layer.

[0021] The sheet separation method of the sheet separation device includes: the adsorption platform comprising a base and an adsorption layer attached to the surface of the base; the base comprising a frame-shaped body and a mesh plate located on the surface of the frame-shaped body; the adsorption layer is attached to the surface of the mesh plate, and a working space is formed on the other side of the mesh plate and inside the other side of the frame-shaped body, for the lifting mechanism located below the working space; the lifting mechanism comprising a top-support module and a lifting module connected to the bottom of the top-support module; the lifting module is for driving the top-support module to move longitudinally. The working space of the frame-shaped body is provided, and the top support module includes a base connected to the top of the lifting module, a shaft embedded in the base, a first top support wheel assembled on the shaft, and at least one second top support wheel located on both sides of the first top support wheel, so that the lifting module can drive the first top support wheel and each of the second top support wheels of the top support module to move longitudinally into and out of the working space of the frame-shaped body and abut against or move away from the bottom surface of the mesh plate, that is, so that the adsorption layer and the sheet on the mesh plate are deformed and bent due to the force at the position where they are pushed.

[0022] The sheet separation method of the sheet separation device includes: the lifting module is a hydraulic cylinder or a pneumatic cylinder, and the lifting module is connected to the lateral displacement module, which drives the lifting module to move horizontally back and forth below the adsorption platform to the working space.

[0023] The sheet separation method of the sheet separation device, wherein: in steps (A03) and (A04), the diameter of the first top support wheel assembled on the shaft by the top support module is greater than the diameter of at least one second top support wheel on each side.

[0024] The main advantage of this invention lies in the sheet separation device and method, which involves a mesh plate attached to the surface of a frame-shaped body on the base of an adsorption platform. An adsorption layer is attached to the surface of the mesh plate, and the other side of the mesh plate forms a working space with the other side of the frame-shaped body. A lifting mechanism is located below the working space of the frame-shaped body. The lifting mechanism is connected to a lifting module at the bottom of the top support module. The lifting module drives the top support module to move longitudinally in and out of the working space. The seat of the top support module is connected to the top of the lifting module, and a shaft is embedded in the seat. A first top support wheel and at least one second top support wheel on each side are assembled on the shaft. The lifting module drives the first top support wheel and each of the second top support wheels of the top support module to move longitudinally in and out of the working space and to abut or move away from the bottom surface of the mesh plate, thereby achieving the purpose of quickly separating the sheet material located on the adsorption platform.

[0025] Another advantage of the present invention lies in the separation method of the sheet separation device, which includes an adsorption platform, a lifting mechanism, and a sheet on the adsorption layer of the adsorption platform. The separation method between the sheet and the adsorption layer is as follows: the lifting mechanism uses a lifting module to drive the top-supporting module to move to the working space at the bottom of the adsorption platform and enter the working space. The first top-supporting wheel assembled on the shaft of the top-supporting module first abuts against the bottom surface of the mesh plate of the adsorption platform, and at least one second top-supporting wheel on each side of the first top-supporting wheel abuts against the bottom surface of the mesh plate of the adsorption platform, forming a large-area abutting effect. The first top-supporting wheel abuts against the bottom surface of the mesh plate and pushes the adsorption layer upward. At the position where the adsorption layer and the sheet are pushed, they deform and bend due to the force, causing the air inside the groove of the adsorption layer to overflow to other grooves and forming a gap between the adsorption layer and the sheet, so as to achieve the purpose of separating the sheet from the adsorption layer.

Detailed Implementation

[0034] To achieve the above objectives and effects, the technical means, construction, and implementation methods of the present invention are described in detail below with reference to the preferred embodiments of the present invention, so as to facilitate a complete understanding.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The figures shown are a three-dimensional appearance view, a three-dimensional appearance view from another perspective, an exploded three-dimensional view of the adsorption platform, an exploded three-dimensional view of the adsorption platform from another perspective, a partial side sectional view, and a partial side sectional view of the lifting mechanism in operation. As can be clearly seen from the figures, the sheet separation device of the present invention includes an adsorption platform 1 and a lifting mechanism 2, wherein:

[0036] The adsorption platform 1 includes a base 11 and an adsorption layer 12 attached to the surface of the base 11. The base 11 includes a frame-shaped body 111 and a mesh plate 112 located on the surface of the frame-shaped body 111. The adsorption layer 12 is attached to the surface of the mesh plate 112, and a working space 110 is formed on the other side of the mesh plate 112 and the other side of the frame-shaped body 111.

[0037] The lifting mechanism 2 is located below the working space 110 at the bottom of the frame-shaped body 111 of the base 11 of the adsorption platform 1. It includes a top support module 21 and a lifting module 22 connected to the bottom of the top support module 21. The lifting module 22 drives the top support module 21 to move longitudinally in and out of the working space 110 of the frame-shaped body 111. The top support module 21 includes a seat 211 connected to the top of the lifting module 22, a shaft 212 embedded in the seat 211, a first top support wheel 213 assembled on the shaft 212, and at least one second top support wheel 214 on each side of the first top support wheel 213. The lifting module 22 drives the first top support wheel 213 and each second top support wheel 214 of the top support module 21 to move longitudinally and lift to enter and exit the working space 110 of the frame-shaped body 111 and to abut or move away from the bottom surface of the mesh plate 112.

[0038] The base 11 of the aforementioned adsorption platform 1 includes a rectangular frame body 111, and an adsorption layer 12 is attached to the surface of the mesh plate 112 on the rectangular frame body 111, the surface of which is provided with a plurality of grooves 120 arranged in an alternating pattern.

[0039] Furthermore, the lifting module 22 of the aforementioned lifting mechanism 2 can be a lifting drive mechanism such as a hydraulic cylinder or a pneumatic cylinder, to drive the top-supporting module 21 to move vertically below the base 11 of the adsorption platform 1, entering and exiting the working space 110 at the bottom of the frame-shaped body 111 of the base 11. The lifting module 22 is further connected to a lateral displacement module 23 at the bottom, which can drive the lifting module 22 to move horizontally back and forth below the adsorption platform 1, so that the top-supporting module 21 above the lifting module 22 is accurately aligned with the working space 110 at the bottom of the frame-shaped body 111 of the base 11. The top of the seat 211 connected to the top of the lifting mechanism 2 is provided with positioning parts 2110 on both sides of the top, and a shaft 212 is provided at the two positioning parts 2110 of the seat 211. The diameter of the first top-supporting wheel 213 assembled on the shaft 212 of the top-supporting module 21 is larger than the diameter of at least one second top-supporting wheel 214 on each side.

[0040] Furthermore, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7The figures shown are a three-dimensional appearance view, a three-dimensional appearance view from another perspective, an exploded three-dimensional view of the adsorption platform, an exploded three-dimensional view of the adsorption platform from another perspective, a partial side sectional view, a partial side sectional view of the lifting mechanism during operation, and a flowchart. As can be clearly seen from the figures, the sheet separation method of the sheet separation device of the present invention includes an adsorption platform 1, a lifting mechanism 2, and a sheet 3 located on the adsorption layer 12 of the adsorption platform 1. The separation method of the sheet 3 from the adsorption layer 12 is based on the following steps:

[0041] (A01) The lifting mechanism 2 uses the lifting module 22 to drive the top support module 21 to move to the working space 110 at the bottom of the frame body 111 of the base 11 of the adsorption platform 1.

[0042] (A02) The top support module 21 enters the working space 110. The first top support wheel 213 assembled on the shaft 212 of the seat 211 of the top support module 21 first abuts against the bottom surface of the mesh plate 112 of the base 11 of the adsorption platform 1.

[0043] (A03) At least one second top roller 214 located on each side of the first top roller 213 on the shaft 212 abuts against the bottom surface of the mesh plate 112 of the base 11 of the adsorption platform 1.

[0044] (A04) The first top roller 213 pushes against the bottom surface of the mesh plate 112 and then pushes the adsorption layer 12 upward. Then, the second top rollers 214 assist the first top roller 213 in pushing against the mesh plate 112 and the adsorption layer 12, thereby generating a large area of ​​pushing action. That is, the adsorption layer 12 and the sheet 3 are deformed and bent due to the force at the pushed position. This causes the air inside at least one groove 120 at the opposite position on the adsorption layer 12 to overflow to the periphery to other grooves 120, supporting the sheet 3 to move upward and forming a gap 30 between the adsorption layer 12 and the sheet 3.

[0045] (A05) can separate the sheet 3 from the adsorption layer 12, so that the sheet 3 can be easily and completely removed from the adsorption platform 1.

[0046] The lifting module 22 of the aforementioned lifting mechanism 2 can be a lifting drive mechanism such as a hydraulic cylinder or a pneumatic cylinder, which can drive the top-support module 21 to move vertically below the base 11 of the adsorption platform 1. The lifting module 22 is further connected to the lateral displacement module 23, which drives the lifting module 22 to move horizontally back and forth below the adsorption platform 1 so that the top-support module 21 can access the working space 110 at the bottom of the frame-shaped body 111 of the base 11.

[0047] In addition, in the above steps (A03) and (A04), the diameter of the first top-supporting wheel 213 assembled on the shaft of the top-supporting module is larger than the diameter of at least one second top-supporting wheel 214 on each side. When the first top-supporting wheel 213 abuts against the adsorption layer 12, the adsorption layer 12 and the sheet 3 are deformed and bent due to the force at the position where they are pushed. As a result, the air inside the groove 120 at the position where the adsorption layer 12 is pushed is squeezed by the deformation and bending between the adsorption layer 12 and the sheet 3 and spills out to the periphery.

[0048] The above description is illustrative only and not restrictive of the present invention. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims, and all such modifications, variations or equivalents will fall within the protection scope of the present invention.
