Fitting jig and film pasting device

Abstract

The present application relates to a fixture comprising a carrier and a plurality of movable members. The carrier has a carrying surface for carrying a target member in a first direction. All the movable members are arranged around the periphery of the carrier and each has a supporting surface for supporting the target member in the first direction. All the movable members are configured to be movable towards or away from the carrier. In a first state, the fixture, all the supporting surfaces are in contact with the carrying surface and together carry the target member. In a second state, the fixture, all the supporting surfaces form a first gap with the carrying surface so that all the supporting surfaces can be separated from the target member. When the target member needs to be processed, the movable members move towards the carrier to carry the target member by the supporting surface of the movable members and the carrying surface of the carrier. When demolding is needed, the movable members move away from the carrier, at this time the first gap is formed between the supporting surface and the carrying surface, so that the target member is separated from the supporting surface, thereby alleviating the problem that the target member is difficult to demold.

[0025] The anti-sticking layer is arranged on the support surface of the movable member along the first direction.

[0026] Another aspect of the present application provides a film bonding device comprising the bonding jig.

[0027] In one of the embodiments, the film bonding device comprises a plurality of first driving members.

[0028] Each of the first driving members is connected with a corresponding movable member to drive the movable member to move towards or away from the carrier.

[0029] In one of the embodiments, the movable member is provided with a connecting hole on the side facing away from the carrier.

[0030] The first driving member is at least partially inserted into the connecting hole to be connected with the movable member.

At this time, due to the existence of certain force between the target piece and the supporting surface, the target piece is difficult to separate from the supporting surface. When the film needs to be removed, the movable member moves away from the carrier, so that the fitting jig is in the second state, and the first gap is formed between the supporting surface and the bearing surface at this time, so as to provide the force for the target piece and the supporting surface to separate from each other, so as to facilitate the separation of the target piece and the supporting surface, and further to alleviate the problem that the target piece is difficult to remove the film.

[0079] In addition, the drawings are not drawn to scale 1:1, and the relative sizes of the elements are only drawn by example in the drawings, not necessarily according to the true scale.

[0080] In order to facilitate the understanding of the technical solutions of the present application, before being described in detail, first of all, the related art of the lamination jig and the film laminating device is described.

[0081] When preparing an optical module, it is usually necessary to laminate a polarizing plate to an optical lens with the help of an optical adhesive layer. Specifically, the polarizing plate is laminated together with the optical adhesive layer, and the optical lens is placed on the carrier of the lamination jig, then the polarizing plate laminated with the optical adhesive layer is placed on the optical lens, and then a certain pressure is applied through the film laminating device, so that the polarizing plate can be completely laminated on the optical lens.

[0082] Figure 1 The structure of the optical module 200 in the related art embodiment is shown.

[0083] AsFigure 1 As shown, the optical module 200 in the related art embodiment includes an optical lens 230, an optical adhesive layer 220 and a polarizer 210 which are sequentially stacked along a first direction (i.e. the z-axis direction in the figure). Figure 1 Specifically, the optical lens 230 includes, but is not limited to, a free-form lens, a spherical lens or a flat lens, etc. Before the polarizer 210 is attached to the optical lens 230, the optical axis needs to be aligned so that the long axis of the optical lens 230 is parallel to the optical axis of the polarizer 210 to ensure reliable polarization of light.

[0084] Figure 2 A structural schematic diagram of the optical lens 230 in the related art embodiment is shown; Figure 3 A sectional view of the optical lens 230 along the A-A direction in the related art embodiment is shown; Figure 4 An attachment schematic diagram of the optical module 200 in the related art embodiment is shown; Figure 5 An attachment process schematic diagram of the optical module 200 in the related art embodiment is shown.

[0085] In combination with Figure 2 and Figure 3 As shown, the structure of the optical lens 230 is an asymmetric irregular 3D curved surface structure. Referring to Figure 4 When attaching the free-form lens, the optical lens 230 needs to be rotated so that its long axis is parallel to the optical axis of the polarizer 210, so a larger polarizer 210 is needed to ensure that the optical lens 230 after rotation can be completely attached by the polarizer 210. The length of the polarizer 210 along the x-axis direction in the figure is defined as d1, and the width of the polarizer 210 along the y-axis direction in the figure is defined as d2. Figure 4 The length of the polarizer 210 along the x-axis direction in the figure is defined as d1, and the width of the polarizer 210 along the y-axis direction in the figure is defined as d2. Figure 4 The length of the polarizer 210 along the x-axis direction in the figure is defined as d1, and the width of the polarizer 210 along the y-axis direction in the figure is defined as d2. For example, the length d1 of the polarizer 210 is 149 mm with an accuracy of 0.5 mm, and the width d2 of the polarizer 210 is 149 mm with an accuracy of 0.5 mm. In order to meet the attachment requirements of the optical lens 230 and ensure that the polarizer 210 can be reliably attached to the optical lens 230, the size of the optical adhesive layer 220 also needs to be larger than that of the optical lens 230. The diameter of the optical adhesive layer 220 is defined as d3. For example, the diameter d3 of the optical adhesive layer 220 is 82 mm with an accuracy of 0.1 mm. Referring to Figure 5 The distance d4 between the outer contour of the optical adhesive layer 220 and the outer contour of the optical lens 230 is defined. The distance d4 is usually set to 5 mm with an accuracy of 0.1 mm.

[0086] Please continue to refer to Figure 5For example, the film attaching device 1000 applies a pressure F of 1.2 MPa to the polarizer 210 on the attaching jig 10 in some of the following embodiments to complete the attachment of the optical module 200, wherein the error range of the pressure F is 10% to apply a relatively stable pressure to the polarizer 210 to ensure the attachment quality. More specifically, the polarizer 210 is applied with a gas of 1.2 MPa to reliably attach the optical adhesive layer 220 and the polarizer 210 to the optical lens 230.

[0087] The inventors of the present application have found that, due to the size of the optical adhesive layer 220 being larger than that of the optical lens 230 and the adhesion of the optical adhesive layer 220 itself, the optical adhesive layer 220 will be attached to the attaching jig 10 beyond the optical lens 230. When the film attaching device 1000 applies a pressure to the polarizer 210 to attach it to the optical lens 230, on one hand, the optical adhesive layer 220 will overflow under the pressure to result in a larger area of the optical adhesive layer 220 being attached to the attaching jig 10. On the other hand, the optical adhesive layer 220 will be more closely attached to the attaching jig 10 with a stronger adhesion. At this time, the optical adhesive layer 220 is attached to the attaching jig 10 to make it difficult to directly take out the completed optical module 200 from the attaching jig 10. If the optical module 200 is forcibly separated from the attaching jig 10, the edges of the adjacent two layers in the optical module 200 will be separated from each other. In order to avoid this, the optical adhesive layer 220 attached to the attaching jig 10 needs to be manually and slowly separated by hand, and after the optical adhesive layer 220 is completely separated from the attaching jig 10, the optical module 200 is taken out from the film attaching device.

[0088] Based on this, the inventors of the present application have made an in-depth study and improved the structure of the attaching jig by dividing the structure of the attaching jig into a movable member and a carrier, and moving the movable member relative to the carrier to separate the optical adhesive layer 220 from the optical module 200 to realize the film stripping and discharging of the optical module 200.

[0089] For the convenience of description, only the structures related to the embodiments of the present application are shown in the drawings.

[0090] Figure 6 Fig. 1 shows a structure schematic view of the attaching jig 100 in a first state according to an embodiment of the present application, Figure 7 Fig. 2 shows a structure schematic view of the attaching jig 100 in a second state according to an embodiment of the present application.

[0091] Referring to Figure 6 and Figure 7 In one aspect of the present application, an attaching jig 100 is provided, which comprises a carrier 110 and a plurality of movable members 120. The carrier 110 has a first direction (i.e. the direction of the arrow in the drawing) and a second direction (i.e. the direction of the arrow in the drawing) perpendicular to the first direction. Figure 6 or Figure 7The carrier 110 has a bearing surface 111 in a first direction (z-axis direction in the figure) for bearing the target object. The plurality of movable members 120 are arranged around the carrier 110 in a circumferential direction, and each of the plurality of movable members 120 has a support surface 121 in the first direction for supporting the target object. The plurality of movable members 120 are configured to be movable toward or away from the carrier 110. The fitting jig 100 has a first state and a second state. In the first state, the plurality of support surfaces 121 abut the bearing surface 111 and together with the bearing surface 111 form a surface for bearing the target object. In the second state, the plurality of support surfaces 121 form a first gap D1 with the bearing surface 111, so that the plurality of support surfaces 121 can be separated from the target object.

[0092] The fitting jig 100 described above bears the target object by the bearing surface 111 of the carrier 110. When the target object needs to be processed, the movable members 120 move toward the carrier 110, so that the fitting jig 100 is in the first state, and the target object is borne by the support surfaces 121 of the movable members 120 and the bearing surface 111 of the carrier 110. At this time, because of the certain force between the target object and the support surfaces 121, the target object is difficult to be separated from the support surfaces 121. When the target object needs to be separated, the movable members 120 move away from the carrier 110, so that the fitting jig 100 is in the second state, and the first gap D1 is formed between the support surfaces 121 and the bearing surface 111, so as to provide a force for separating the target object from the support surfaces 121, and facilitate the separation of the target object from the support surfaces 121, thereby alleviating the problem that the target object is difficult to be separated.

[0093] In combination with some of the foregoing embodiments, the target object in the present application is exemplarily an optical module 200, wherein the optical adhesive layer 220 in the optical module 200 is adhered to the support surfaces 121 in the fitting jig 100 due to the adhesive force. That is, the target object and the support surfaces 121 have the adhesive force therebetween, which makes it difficult to be separated. It should be understood that the fitting jig 100 and the film-attaching device 1000 in the present application are used for the preparation of the optical module 200 as an example, which is used for explanation and illustration, but not limitation. In some other embodiments, it can also be used for other target objects that need to be separated, which is not limited herein.

[0094] It should be noted that all the movable members 120 are arranged along the circumference of the carrier 110. When the movable members 120 are away from the carrier 110, the adhering jig 100 is switched from the first state to the second state, and a force perpendicular to the first direction is generated by the movable members 120, so that the optical adhesive layer 220 is separated from the supporting surface 121 of the movable members 120. In this way, the direction of the force actually acting on the optical adhesive layer 220 and the movable members 120 when they are separated is not the force from the first direction when the optical adhesive layer 220 is directly peeled off from the movable members 120, thereby alleviating the problem that the target member is difficult to separate from the adhering jig 100, and avoiding the defect that the target member is separated and interlayer separation occurs.

[0095] The target member is taken as the optical module 200 for further description in combination with the related drawings.

[0096] Specifically, Figure 6 and Figure 7 In the embodiments shown in the drawings, the adhering jig 100 includes four movable members 120. Among the four movable members 120, the edges of two adjacent movable members 120 can coincide with the long axis and the short axis of the optical lens 230, respectively.

[0097] The inventor has found that if the size of the first gap D1 is less than 5 mm, part of the optical adhesive layer 220 will still adhere to the supporting surface 121, which will make it difficult to meet the demolding requirement. If the size of the first gap D1 is greater than 9 mm, the space occupied by the movable members 120 in the second state will be increased, which will further cause the size of the film pasting device 1000 in some embodiments to be larger. In some embodiments, the first gap D1 includes 5 mm-9 mm. It can be understood that the first gap D1 can be, but is not limited to, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, or 9 mm.

[0098] Referring to Figure 7 In some embodiments, when the adhering jig 100 is in the first state, the plurality of movable members 120 enclose the first accommodating cavity 130, and the carrier 110 is located in the first accommodating cavity 130. The inner contour shape of the first accommodating cavity 130 is matched with the outer contour shape of the carrier 110. In combination with the foregoing embodiments, when the adhering of the optical module 200 is completed, a pressure needs to be applied to the optical module 200. By matching the outer contour shape of the carrier 110 with the first accommodating cavity 130, it can be ensured that the abutment between the supporting surface 121 and the carrier 110 is more reliable when all the movable members 120 are in the first state, thereby avoiding the displacement of the movable members 120 and the carrier 110 due to the unreliable abutment therebetween when the optical module 200 is pressed and transmits the pressure to the supporting surface 121 and the carrier 110.

[0099] Please refer to Figure 2 ,Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the outer shape of the bearing surface 111 is adapted to the outer shape of the target component. In this way, the carrier 110 can more reliably support the target component (i.e., the optical module 200). Moreover, in conjunction with the aforementioned embodiments, when the optical module 200 is subjected to pressure, it can prevent the optical lens 230 in the optical module 200 from being subjected to uneven force or even damaged due to mismatch with the bearing surface 111.

[0100] Please refer to it again. Figure 7 In some embodiments, the carrier 110 has a light emission channel 112. The light emission channel 112 is used to provide a path for light to exit in order to position the target component. In this way, the target component (i.e., the optical module 200) can be positioned, thereby ensuring that when the polarizer 210 and the optical adhesive layer 220 are attached to the optical lens 230, the optical axis of the polarizer 210 remains parallel to the long axis of the optical lens 230.

[0101] Figure 8 A perspective view of an adhesive jig 100 according to an embodiment of the present invention is shown. The perspective view is used to show the internal structure of the adhesive jig 100 for clarity.

[0102] like Figure 8 As shown, in some embodiments, the fitting fixture 100 further includes a base 140. A carrier 110 is mounted on the base 140. A movable member 120 is movably disposed on the base 140. Thus, the base 140 provides a more reliable mounting position for the carrier 110 and the movable member 120. Specifically, in some embodiments, one of the movable member 120 and the base 140 is provided with a slider 122, and the other of the movable member 120 and the base 140 is provided with a slide rail 141. The slider 122 is slidably connected to the slide rail 141. Thus, the slide rail 141 and the slider 122 can guide the movement of the movable member 120 relative to the carrier 110, thereby improving the smoothness of the movable member 120 moving towards or away from the carrier 110. Specifically, in the embodiments exemplified in this application, the movable member 120 is provided with a slider 122, and the base 140 is provided with a slide rail 141.

[0103] See Figure 8 In some embodiments, one of the movable member 120 and the carrier 110 is provided with a magnetic member 123. The other of the movable member 120 and the carrier 110 is provided with a magnetic member 123 or is a magnetically pleasing member 113. Thus, when all movable members 120 are in the first state, the magnetic attraction ensures that the movable member 120 is more securely attached to the periphery of the carrier 110 without moving. Specifically... Figure 8In this embodiment, the movable member 120 is provided with a magnetic attracting member 123, and the carrier 110 is provided with a magnetically attractable member 113. Alternatively, the movable member 120 itself can be a magnetic attracting member, and the carrier 110 itself can be a magnetically attractable member. It should be noted that the property of an object to be attracted or repelled by an external magnetic field is called the object's magnetism, and magnetic attraction refers to the ability of an object to be attracted by an external magnetic field when it is subjected to such a field. Exemplarily, the magnetic attracting member 123 can be, but is not limited to, a magnet, and the magnetically attractable member 113 can be, but is not limited to, a metal part that can be attracted by a magnet, as long as it ensures that the movable member 120 and the carrier 110 can be attracted to each other by magnetic attraction to securely adhere.

[0104] Figure 9 A schematic diagram of a first projection 111a and a second projection 230a in one embodiment of the present invention is shown.

[0105] See Figure 9 In some embodiments, the bearing surface 111 is in the first direction (i.e., Figure 6 The orthographic projection of the target component onto a plane perpendicular to the z-axis direction is the first projection 111a, and the orthographic projection of the target component onto a plane perpendicular to the first direction is the second projection 230a. The second projection 230a covers the first projection 111a. That is, the optical adhesive layer 220 in the target component will not adhere to the bearing surface 111. In this way, the increased difficulty of demolding due to the optical adhesive layer 220 in the optical module 200 adhering to the bearing surface 111 can be avoided.

[0106] Figure 10 A schematic diagram of the anti-stick layer 150 in one embodiment of the present invention is shown.

[0107] In some embodiments, the fitting fixture 100 further includes an anti-adhesive layer 150. The anti-adhesive layer 150 is along a first direction (i.e., Figure 6The anti-adhesive layer 150 (located along the z-axis) is positioned on the support surface 121 of the movable member 120. Thus, the anti-adhesive layer 150 further enhances the ease of separation between the optical adhesive layer 220 and the support surface 121. Specifically, in some embodiments, the anti-adhesive layer 150 is made of a hydrophobic coating. Optionally, the anti-adhesive layer 150 can be made of PTFE (Polytetrafluoroethylene), fluorinated polyethylene, and PFA (Perfluoroalkoxy), or other fluorine / silicone materials or polymers, etc., and is not limited thereto. The inventors found that the Teflon anti-adhesive layer 150 is more effective; therefore, in the embodiments of this application, the anti-adhesive layer 150 is made of Teflon. More specifically, Teflon material has poor processing performance. In order to ensure that the fitting jig 100 still meets the accuracy requirements after processing and assembly, the anti-stick layer 150 is applied to the support surface 121 of the moving part 120.

[0108] Based on the same inventive concept. Figure 11 A simplified structural diagram of a film-applying device 1000 according to an embodiment of the present invention is shown. Another aspect of the present invention provides a film-applying device 1000 including the aforementioned bonding fixture 100. By using the aforementioned bonding fixture 100, after bonding the optical module 200 exemplified in this application is completed, the movable member 120 moves away from the carrier 110 to separate the support surface 121 from the target part, thereby satisfying both the bonding requirements and the requirements for film removal and unloading. Specifically, the film-applying device 1000 includes a force-applying member 400 and a support member 500, the force-applying member 400 being configured to be able to move relative to the support member 500 in a first direction (i.e., in a... Figure 11 The optical module 200 reciprocates along the z-axis direction. This allows the force-applying member 400 to approach and abut against the support member 500 in the first direction, forming a sealed space. High-pressure gas is then used to apply force to the optical module 200. After bonding, the force-applying member 400 moves away from the support member 500 in the first direction to expose the optical module 200, facilitating subsequent processes such as demolding and unloading. It should be noted that, in the aforementioned embodiment of the optical module 200, the edge of the polarizer 210 in the optical module 200 is circumferentially clamped between the force-applying member 400 and the support member 500, thus positioning the polarizer 210 before bonding. This facilitates the force-applying member 400 applying pressure to the polarizer 210 and the optical adhesive layer 220, thereby achieving the bonding and fabrication of the optical module 200.

[0109] Figure 12 A schematic diagram of a first driving member 300 and a movable member 120 in one embodiment of the present invention is shown.

[0110] like Figure 12As shown in the embodiments, in some embodiments, the film pasting device 1000 comprises a plurality of first driving members 300. Each first driving member 300 is connected with a corresponding movable member 120 to drive the movable member 120 to move towards or away from the carrier 110. In this way, the first driving member 300 can more stably drive the movable member 120 to move. In some embodiments, the first driving member 300 comprises a motor. The motor not only has a fast response speed, but also has a high precision, and can accurately drive the movable member 120 to move relative to the carrier 110.

[0111] In combination with Figure 12 With Figure 6 Or Figure 7 As shown in the embodiments, in some embodiments, the side of the movable member 120 away from the carrier 110 is provided with a connecting hole 124. The first driving member 300 at least partially extends into the connecting hole 124 to be connected with the movable member 120. In this way, the connecting hole 124 can provide a mounting position for the first driving member 300, and the first driving member 300 extending into the connecting hole 124 can further save space and improve space utilization. In some embodiments, the first driving member 300 is detachably connected with the hole wall of the connecting hole 124. In this way, the assembly connection between the first driving member 300 and the movable member 120 is more convenient. More specifically, the first driving member 300 is clamped with the hole wall of the connecting hole 124. More specifically, the first driving member 300 is tenon-and-mortise connected with the hole wall of the connecting hole 124. In this way, the first driving member 300 and the movable member 120 can be tightly and firmly connected. In the embodiments as shown in the drawings, the first driving member 300 is tenon-and-mortise connected with the hole wall of the connecting hole 124. Figure 6 Or Figure 7 In the embodiments as shown in the drawings, the connecting hole 124 is in the shape of "T".

[0112] Figure 13 As shown in the embodiments, in some embodiments, the film pasting device 1000 comprises a plurality of first driving members 300. Each first driving member 300 is connected with a corresponding movable member 120 to drive the movable member 120 to move towards or away from the carrier 110. In this way, the first driving member 300 can more stably drive the movable member 120 to move. In some embodiments, the first driving member 300 comprises a motor. The motor not only has a fast response speed, but also has a high precision, and can accurately drive the movable member 120 to move relative to the carrier 110. Figure 14 As shown in the embodiments, in some embodiments, the film pasting device 1000 comprises a plurality of first driving members 300. Each first driving member 300 is connected with a corresponding movable member 120 to drive the movable member 120 to move towards or away from the carrier 110. In this way, the first driving member 300 can more stably drive the movable member 120 to move. In some embodiments, the first driving member 300 comprises a motor. The motor not only has a fast response speed, but also has a high precision, and can accurately drive the movable member 120 to move relative to the carrier 110.

[0113] In combination with Figure 13 And Figure 14 As shown in the embodiments, in some embodiments, the film pasting device 1000 has a first direction (i.e. the direction of the arrow in the drawings) and a second direction (i.e. the direction of the arrow in the drawings). Figure 13 Or Figure 14The supporting member 500 has a supporting surface 510 in the first direction (z-axis direction in the figure) for supporting the target member, and the film pasting device 1000 has a second accommodating cavity 520. The pasting jig 100 is located in the second accommodating cavity 520, and the pasting jig 100 is configured to be able to reciprocate along the first direction, and the pasting jig 100 has a first position and a second position during movement. When the pasting jig 100 is in the first position, the pasting jig 100 is in the first state, and all the supporting surfaces 121 are in contact between the supporting surface 510 and the bearing surface 111, and the supporting surface 510, the bearing surface 111 and the supporting surfaces 121 together form a surface for supporting the target member. When the pasting jig 100 is in the second position, the supporting surface 510 and the supporting surface 121 form a second gap D2, so that the supporting surface 121 can be separated from the supporting surface 510.

[0114] Therefore, when the target member (i.e. the optical module 200) needs to be processed, the pasting jig 100 moves to the first position when the optical module 200 needs to be processed, so that the optical lens 230 in the optical module 200 is cooperatively borne by the supporting surface 510, the supporting surface 121 and the bearing surface 111 in sequence, so that the film pasting device 1000 can press the polarizing plate 210, realize the pasting of the polarizing plate 210, the optical adhesive layer 220 and the optical lens 230, and then obtain the optical module 200. When the film needs to be removed, the pasting jig 100 moves to the second position, and the second gap D2 formed between the supporting surface 510 and the supporting surface 121 allows the edge portion of the optical adhesive layer 220 in the optical module 200 to be separated from the supporting surface 121 to realize pre-removal, so that when the pasting jig 100 switches to the second state, the ease of movement of the movable member 120 relative to the carrier 110 can be improved, and the ease of removal can be improved. Wherein, in combination with the foregoing Figure 12 In the embodiment shown, the second accommodating cavity 520 is arranged in the supporting member 500 along the first direction.

[0115] Please continue to refer to Figure 14 The inventor has found that if the second gap D2 is less than 1.5 mm, the edge portion of the optical adhesive layer 220 cannot be separated from the supporting surface 121, and the pre-removal effect cannot meet the requirements. If the second gap D2 is greater than 2.5 mm, the edge portions of the adjacent two layers of the optical module 200 are separated from each other, which causes the optical adhesive layer 220 to be torn from the optical lens 230. Therefore, in some embodiments, the second gap D2 is 1.5 mm-2.5 mm. It can be understood that the second gap D2 includes but is not limited to 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm or 2.5 mm.

[0116] Please continue to refer to Figure 14In some embodiments, the film application device 1000 further includes a second driving member. The second driving member is connected to the bonding fixture 100 to drive the bonding fixture 100 along a first direction (i.e., Figure 14 The second driving member reciprocates along the z-axis direction. This allows for more reliable driving of the bonding fixture 100. In some embodiments, the second driving member includes a motor. The motor not only has a fast response speed but also higher precision, enabling accurate driving of the bonding fixture 100 relative to the cavity wall of the second receiving cavity 520. Furthermore, the film-applying device 1000 also includes a transmission member, which is connected between the second driving member and the bonding fixture 100. Thus, by transmitting the driving force of the second driving member through the transmission member, reliable transmission can be ensured while more easily adjusting the arrangement of the components in the film-applying device 1000. For example, the transmission member may be, but is not limited to, a lead screw. Thus, the lead screw can convert the rotational motion of the motor into linear motion, thereby realizing the reciprocating motion of the bonding fixture 100 in the first direction. In other embodiments, it may also be a rack and pinion drive, belt drive, or other transmission methods, which are not limited here.

[0117] The bonding fixture 100 provided in this embodiment supports the optical lens 230 in the optical module 200 via the bearing surface 111 of the carrier 110. When the optical module 200 needs to be processed and bonded, the movable member 120 moves toward the carrier 110, so that the bonding fixture 100 is in a first state. The optical lens 230 in the optical module 200 is supported by the cooperation between the support surface 121 of the movable member 120 and the bearing surface 111 of the carrier 110. During the bonding process, due to the certain force between the optical adhesive layer 220 in the optical module 200 and the support surface 121, it is difficult to separate from the support surface 121. When demolding is required, the movable part 120 moves away from the carrier 110, placing the bonding fixture 100 in a second state. At this state, a first gap D1 is formed between the support surface 121 and the bearing surface 111, providing a force to separate the optical adhesive layer 220 from the support surface 121, thus facilitating the separation of the optical adhesive layer 220 from the support surface 121 and alleviating the problem of difficult demolding of the optical module 200. Simultaneously, the first gap D1 is 5 mm to 9 mm, ensuring demolding requirements are met while avoiding excessive space occupation. The base 140 in the bonding fixture 100 is slidably connected to the movable part 120 via a slide rail 141 and a slider 122, guiding the movement of the movable part 120 toward or away from the carrier 110. When the movable part 120 is in the first state, it is magnetically attached to the carrier 110, ensuring the stability of the movable part 120. The anti-stick layer 150 further enhances the ease of separation between the optical adhesive layer 220 and the support surface 121.

[0118] The film pasting device 1000 using the pasting jig 100, through the movement of the pasting jig 100 relative to the cavity wall of the second accommodating cavity 520 along the first direction, in the first position, combined with the first state of the pasting jig 100, through the cooperation of the supporting surface 510, the supporting surface 121 and the bearing surface 111, the optical lens 230 is supported together, so as to realize the pasting of the film pasting device 1000 to the polarizer 210. While the pasting jig 100 is in the second position, the supporting surface 510 is separated from the optical adhesive layer 220 to realize the pre-debonding. Among them, the second gap D2 between the supporting surface 510 and the supporting surface 121 is 1.5mm-2.5mm, so as to ensure the debonding effect while avoiding the separation between the layers of the optical module 200. Then, the pasting jig 100 is switched from the first state to the second state, and the movable part 120 is separated from the carrier 110 to realize the complete separation of the optical module 200 and the pasting jig 100.
