Description

Technical Field

[0001] The utility model relates to the technical field of polarizing films, in particular to a polarizing film attaching device. Background Art

[0002] With the development of the automotive market, there are increasingly higher requirements for the contrast of display modules, from the earlier minimum contrast of 500 to 800, and the current requirement is a minimum of 1200. This is an increasingly greater extreme challenge in the display industry.

[0003] The display module processing, especially the angle matching of the front and rear polarizers, is always affected by multiple tolerances. The polarizer itself has a cutting size tolerance. During the polarizer processing process, there will also be an angle matching tolerance between TAC and PVA, and there will also be a cutting tolerance for glass cutting. The accumulation of multiple tolerances will result in the angle matching between the front and rear polarizers not being optimal after the polarizer is attached. There may be a difference of 0.2~0.4 degrees. When this deviation occurs, the brightness of the black screen may change from 0.1 to 0.5 or even more, or from 0.5cm / m2 to 0.8cd / m2 or even 1.0cd / m2, 1.5cd / m2.

[0004] Assuming that the brightness of the white screen is 1000cd / m2, the polarization degree of a conventional polarizer is 99.99%, that is, in theory, the contrast of the polarizer can be 43.2 / (1-99.9%)=41000. However, if the angle matching deviation of the front and rear polarizers is 0.1 or 0.2 degrees or more, the actual measured contrast is only a few hundred to 1500, generally not exceeding 2000, and this is without considering the light leakage effect of the liquid crystal box itself (light leakage caused by the arrangement of liquid crystal molecules, etc.). Taking the measured contrast of 1000 as an example, that is, the brightness of the white screen is 1000cd / m2, the brightness value of the black screen can reach 1.0cd / m2. This is usually fatal to the display specification requirements. For this reason, the present application proposes a polarizer attachment device. Utility Model Content

[0047] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0048] As mentioned in the background technology, the display module processing, especially the angle matching of the front and rear polarizers, is always affected by multiple tolerances. The polarizer itself has a cutting size tolerance. During the polarizer processing process at the manufacturer, there will also be an angle matching tolerance between TAC and PVA, and there will also be a cutting tolerance for glass cutting. The accumulation of multiple tolerances will result in a non-optimal angle matching between the front and rear polarizers after the polarizers are attached.

[0049] In order to solve this technical problem, the utility model provides a polarizer attaching device, which is used for polarizer attaching.

[0050] Specifically, please refer to Figure 1-Figure 9 , the polarizer attaching equipment specifically includes:

[0051] A support base 1, with guide rails 11 on both sides of the upper surface of the support base 1;

[0052] A horizontal sliding element 2, which is arranged on the support seat 1 and is used for assembly with the guide rail 11;

[0053] The patch platform 3 is arranged on the horizontal sliding element 2 for carrying the display module 14. The patch platform 3 is provided with a transparent rotating table 31. The patch platform 3 is provided with a rotating structure 32 for assembling with the transparent rotating table 31 to adjust the angle of the display module 14.

[0054] A conveyor belt 13 is provided on one side of the support base 1 for conveying the polarizer 12 to be mounted. A linear adjustment module 5 is also provided on one side of the conveyor belt 13. A vacuum adsorption plate 51 is mounted on the linear adjustment module 5.

[0055] An optical lens 510 is installed at the center position below the vacuum adsorption plate 51 for capturing light passing through the polarizers 12 on both sides of the display module 14 , and a vacuum adsorption silicone head 511 connected to the vacuum adsorption plate 51 is distributed outside the optical lens 510 .

[0056] The polarizer attaching device provided by the utility model can perform the pressing and attaching operation in a normal manner through the pressing element 6 when attaching the first polarizer 12. The other polarizer 12 is attached to the glass, and the brightness of the light after passing through the two polarizers 12 is captured by the optical lens 510 above. By driving the rotating structure 32, the display module 14 with a single polarizer 12 on the attaching platform 3 is adjusted in a small angle, so that the brightness of the light passing through the two polarizers 12 is rotated to achieve dynamic changes. The operation is assisted by capturing the dynamically changing brightness in the optical lens 510. When the captured light brightness is the set optimal value, the vacuum adsorption silicone head 511 releases the adsorption of the polarizer 12, so that it is placed under the pressing element 6 through the horizontal sliding element 2 to perform the attaching operation.

[0057] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0058] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0059] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0060] Please refer to Figure 1-Figure 9 , a polarizer attaching device, a support seat 1, with guide rails 11 on both sides of the upper surface of the support seat 1; a horizontal sliding element 2, which is arranged on the support seat 1 and is used for assembly with the guide rails 11; a mounting table 3, which is arranged on the horizontal sliding element 2 and is used for carrying a display module 14;

[0061] A transparent rotating table 31 is provided on the patch table 3. A rotating structure 32 is provided inside the patch table 3 for assembling with the transparent rotating table 31 to adjust the angle of the display module 14. A groove is provided on the rotating transparent table 31 for the display module 14 to be embedded therein. After embedding, the display module 14 is still slightly higher than the rotating transparent table 31 to ensure the stability of the display module 14 in the attached state.

[0062] like Figure 1As shown, a conveyor belt 13 is provided on one side of the support base 1 for conveying the polarizer 12 to be mounted, and a linear adjustment module 5 is also provided on one side of the conveyor belt 13, on which a vacuum adsorption plate 51 is mounted, wherein an optical lens 510 is installed at the center position below the vacuum adsorption plate 51, for capturing and collecting light passing through the polarizers 12 on both sides of the display module 14, and a vacuum adsorption silicone head 511 connected to the vacuum adsorption plate 51 is distributed on the outer side of the optical lens 510;

[0063] The optical lens 510 is connected to an external computer program, and the collected data is analyzed by the computer equipment for actual reference and application by the operator. The conveyor belt 13 is used to convey the polarizer to be attached, and is assembled with the external equipment for use in the actual application process;

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, a pressing element 6 is provided on one side of the support base 1 for pressing and attaching the polarizer 12;

[0065] The rotating structure 32 includes a high-precision motor 320 fixed in the mounting platform 3, a gear 321 connected to the output end of the high-precision motor 320, and a gear ring 322 meshed with one side of the gear 321;

[0066] The transparent rotating table 31 is movably embedded on the top of the patch table 3 , wherein the gear ring 322 is fixed to the bottom of the transparent rotating table 31 and is coaxially arranged therewith.

[0067] When attaching the polarizer 12 to the display module 14, Figure 1 In the state shown, the polarizer 12 to be attached is adsorbed by the vacuum adsorption silicone head 511 on the vacuum adsorption plate 51 and moved above the display module 14. When it reaches the specified position, the adsorption of the polarizer 12 is released. At this time, the polarizer 12 is adsorbed on the display module 14, and then the display module 14 with the polarizer 12 is moved below the pressing element 6 by driving the horizontal sliding element 2. The polarizer 12 is pressed and attached by the pressing element 6, and the attachment of a single polarizer 12 is achieved.

[0068] When attaching the polarizer 12 to the other side of the display module 14, the display module 14 is turned over by moving the external attachment stage 3, so that the surface to be attached faces upward and the attached polarizer 12 faces downward, and then the above steps are repeated to adsorb the polarizer 12 on the top of the display module 14 through the vacuum adsorption silicone head 511 and leave a small gap. At this time, the optical lens 510 can capture the brightness through the two polarizers;

[0069] Then, the high-precision motor 320 is driven to rotate the gear 321. During the rotation process, the gear 321 meshes with the corresponding gear ring 322 on the outside to synchronously realize the rotation of the transparent rotating table 31. The rotating transparent rotating table 31 will drive the display module 14 placed thereon to rotate to adjust the relative angle between the attached polarizer and the polarizer to be attached, so that the brightness of the light passing through the two polarizers 12 is dynamically changed by the rotation. The operation is assisted by capturing the dynamically changing brightness in the optical lens 510. When the captured light brightness is the set optimal value, the vacuum adsorption silicone head 511 releases the adsorption of the polarizer 12, so that the polarizer 12 is adsorbed on the display module 14, and then the horizontal sliding element 2 is used to move it to the bottom of the clamping element 6 for further compression and attachment.

[0070] The polarizer attachment device provided in Example 1 is further optimized, specifically, Figure 4 As shown, the horizontal sliding element 2 includes a bearing seat 21 slidably disposed on the guide rail 11 and a driving screw 22 threadedly assembled on the bearing seat 21, and a driving motor 23 fixed to the support seat 1 is fixed at one end of the driving screw 22;

[0071] In Example 1, after the polarizer 12 is lowered by the vacuum adsorption plate 51 for subsequent pressing and attachment, the driving motor 23 is started to drive the driving screw 22 to rotate, and the supporting seat 21 subjected to the driving force will slide along the length direction of the guide rail 11, thereby driving the patch stage 3 and the display module 14 with the patch thereon to move in position.

[0072] The polarizer attachment device provided in Example 1 is further optimized, such as Figure 5 , Figure 6 and Fig. 9 As shown, the patch table 3 is fixed on the top of the supporting base 21, and a fill light source 24 is provided between the supporting base 21 and the patch table 3, wherein a groove 25 is formed at the bottom of the patch table 3 corresponding to the position of the fill light source 24, which is used for the fill light source 24 to radiate onto the display module 14 through the patch table 3 and the transparent rotating table 31. Through the setting of the fill light source 24, fill light within a reasonable value range can be performed below the polarizer 12 according to actual conditions. Through the effect of fill light, the optical lens 510 can more easily capture the brightness after passing through the two polarizers 12. However, when the external program performs collection and calculation, it is necessary to take into account the additional fill light value. When there is sufficient external light, the fill light source 24 may not be used for fill light.

[0073] The polarizer attachment device provided in Example 1 or 2 is further optimized, such as Figure 1-Figure 4As shown, the pressing element 6 includes a support frame 61 fixed on the support seat 1, a support plate 62 movably installed in the support frame 61, and an electric push rod 63 provided on the support plate 62;

[0074] A support rod 64 is fixed to the end of the electric push rod 63, and the support rod 64 is rotatably arranged inside the support frame 61. A connecting piece 65 is fixed to the output end of the electric push rod 63, and the top of the support plate 62 is movably connected to the connecting piece 65 through a pin shaft.

[0075] An assembly frame 66 is fixed to one side of the lower surface of the support plate 62, and a pressing roller 67 is rotatably mounted on the inner side of the assembly frame 66;

[0076] In Examples 1 and 2, after the display module 14 and the polarizer 12 to be pressed and attached are moved to the bottom of the pressing element 6 by the horizontal sliding element 2, the electric push rod 63 is started to make its output end act on the support plate 62 through the connecting piece 65. The support plate 62 subjected to the force will deflect along the movable part of the support frame 61 at an angle so that the pressing roller 67 contacts the display module 14 below, thereby pressing the polarizer 12. Then, by adjusting the horizontal movement of the supporting seat 21, the pressing roller 67 rolls on the surface of the display module 14 and the upper polarizer 12, and the polarizer 12 is completely pressed and attached to the display module 14 to complete the attachment action.

[0077] The polarizer attachment device provided in Example 3 is further optimized, such as Figure 8 As shown, the linear adjustment module 5 includes a vertical plate 57, a screw rod 1 52 disposed in the vertical plate 57, a horizontal plate 53 threadedly assembled with the screw rod 1 52, and a screw rod 2 54 disposed in the horizontal plate 53;

[0078] One end of the screw rod 1 52 and the screw rod 2 54 are fixed with a motor 55 which is respectively fixed to the corresponding vertical plate 57 and horizontal plate 53;

[0079] The surface of the screw rod 54 is threadedly equipped with a slider 58, and a connecting frame 56 is fixed to one side of the slider 58. The vacuum adsorption plate 51 is fixed to the outer end of the connecting frame 56, and the conveyor belt 13 and the vertical plate 57 are connected to the external support.

[0080] Starting the two motors 55 can respectively drive the corresponding screw rod 1 52 and screw rod 2 54 to rotate. During the rotation process, the screw rod 1 52 and screw rod 2 54 will drive the corresponding cross plate 53 and slider 58 to slide, thereby adjusting the position of the connecting frame 56 connected to the slider 58 to meet the vacuum adsorption disk 51 thereon to adsorb and transport the polarizer 12 on the conveyor belt 13.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
