Description

Technical Field

[0001] The invention relates to the field of processing of polarizers, and in particular to a forming processing method of a polarizer. Background Art

[0002] Polarizer is a functional optical film composed of multiple layers of thin film materials, which is widely used in various display technologies. The polarizer in the liquid crystal display is one of the core components to realize the liquid crystal display technology. The main function of the polarizer is to control the polarization direction of light, so as to realize the display of the image. It is an indispensable part of the liquid crystal display. The current molding and processing of polarizers mainly includes five steps: mechanical cutting, rounding and edging, cleaning, quality inspection and packaging and storage. Among them, rounding and edging refers to the use of edging equipment to grind the four corners of the small polarizer cut by the machine into a rounded shape to improve the flexibility and damage resistance of its edges. At the same time, it can also reduce the sharpness of the edges, reduce the risk of scratches on the human body during use, and provide a better appearance effect.

[0003] However, there are still the following problems in the process of rounding and grinding the polarizer:

[0004] 1. It is difficult to implement accurate and stable rounding and edging operations on polarizers that are not centered. At the same time, the polarizers are easily moved or misaligned due to the grinding force during the edging process, resulting in poor precision and accuracy of rounding and edging. It takes time to continuously adjust and correct the position of the polarizers during the edging process, which is not conducive to improving the overall production efficiency.

[0005] 2. The edges of the polarizer after mechanical cutting are relatively rough and have many burrs. Rounding the corners corner by corner not only takes a lot of time and energy and is inefficient, but also is affected by subjective factors, resulting in differences in the angles and sizes of the edges at different corners, which in turn leads to poor quality and consistency of the rounded corners of the polarizer.

[0006] Therefore, in order to solve the problems existing in the rounded edge grinding process of the polarizer, the present invention provides a forming method of the polarizer. Summary of the invention

[0010] S3. Cleaning: Thoroughly clean the polarizer after laser cutting to remove dust, particles and contaminants on the surface of the polarizer.

The assembly includes a tooth plate 216, and tooth plates 216 are installed in the middle of the left and right ends of the mounting plate 211 and the middle of the left and right ends of the movable plate 213. A gear column 217 is meshed between the left and right opposite tooth plates 216, and the left end of the leftmost tooth plate 216 and the right end of the rightmost tooth plate 216 are meshed with the same gear column 217. The gear column 217 is rotatably installed between the front and rear vertical plates fixedly connected to the upper end of the fixed platform 2. A push column 218 that slides through the fixed platform 2 is installed in the middle of the lower end of the left and right movable plates 213. A push plate 219 is commonly installed between the lower ends of the left and right push columns 218. The lower end of the push plate 219 is connected to the push end of a left-right symmetrical automatic push rod 220, and the automatic push rod 220 is installed at the upper end of the base 1.

[0047] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The fixing unit 21 also includes a centering positioning component arranged at the upper end of the fixing platform 2, and the centering positioning component includes a positioning plate 231 symmetrically installed at the upper end of the left side of the fixing platform 2. The fixing platform 2 is provided with a rectangular through groove 232 symmetrically located between the left and right adjacent guide columns 215. A side abutment plate 233 is slidably installed in the rectangular through groove 232. A control component for driving the side abutment plate 233 to move forward and backward is arranged below the fixing platform 2. Elastic rubber is installed on the right end of the positioning plate 231 and the side close to the front and rear side abutment plates 233. The rubber pad, the control component includes a horizontal plate 234 which is symmetrical front and back and connected to the base 1 for front and back sliding, and the side abutment plates 233 on the same side are installed on the upper end of the same horizontal plate 234. The middle part of the upper end of the side close to the front and rear horizontal plates 234 is hinged with a connecting rod 235, and the other ends of the front and rear connecting rods 235 are hinged to a rotating plate 236 rotatably installed on the upper end of the base 1. The rotating plate 236 is located below the push plate 219, and the front right front end of the horizontal plate 234 located on the rear side is connected to the pushing end of the cylinder 237, and the cylinder 237 is installed on the upper end of the base 1.

[0048] During the molding process of the polarizer, the first step is to first use the existing laser cutting machine 227 to cut the large polarizer into small polarizers according to a predetermined shape and size to match the size and design requirements of different LCD screens.

[0049] Step 2: Then the cut small polarizer can be placed on the upper end of the flexible ball 214 on the left-right movable plate 213. In the initial state, the distance between the flexible ball 214 and the fixed platform 2 is greater than the distance between the upper end surface of the flexible tray 212 and the fixed platform 2. Therefore, the polarizer at this time is only supported by the flexible ball 214 and does not contact the flexible tray 212. When placing the polarizer, make the left end of the polarizer fit the right end of the positioning plate 231. The positioning plate 231 can limit the left end of the polarizer to ensure the accuracy of the polarizer position in the left-right direction and avoid the polarizer from being offset or misplaced.

[0050] After the polarizer is placed, the cylinder 237 can be used to drive the horizontal plate 234 on the rear side to move forward along the base 1. At the same time, the connecting rod 235 on the rear side rotates around the hinge point between it and the rear horizontal plate 234. The other end of the rear connecting rod 235 drives the rotating plate 236 to rotate synchronously around the rotation point between it and the base 1. Similarly, when the rotating plate 236 rotates, the connecting rod 235 on the front side drives the front horizontal plate 234 to move synchronously backward along the base 1, thereby realizing the synchronous movement of the front and rear horizontal plates 234 toward each other. The side abutment plates 233 on the front and rear sides respectively move synchronously along the rectangular through grooves 232 with the corresponding horizontal plates 234. Until the side abutment plates 233 on the front and rear sides simultaneously fit the front and rear ends of the polarizer, at this time the position of the polarizer is in a front-to-back centered state, during this process, the side abutment plates 233 on the front and rear sides can push the polarizer that is not centered front-to-back to move forward and backward along the flexible ball bearings 214, the flexible ball bearings 214 can not only support and protect the polarizer to ensure the stability of the polarizer, but also reduce the friction force on the polarizer during movement, so as to smoothly complete the centering adjustment of the polarizer position, in addition, the positioning plate 231 and the side abutment plates 233 all use elastic rubber pads to contact the polarizer, which is beneficial to prevent the polarizer from being damaged, deformed or broken when it is resisted.

[0051] After the polarizer is centered, the side abutment plates 233 on the front and rear sides can be synchronously moved in the opposite direction to a position slightly away from the polarizer in the opposite manner as described above, and then the push plates 219 can be driven to move downward at the same time by the automatic push rods 220 on the left and right sides, and the push plates 219 drive the movable plates 213 on the left and right sides to move downward synchronously along the corresponding guide columns 215 through the push columns 218, and the polarizer moves downward synchronously with the left and right movable plates 213, and at the same time, the side abutment plates 233 on the front and rear sides can guide the polarizer during the downward movement. In this process, the tooth plates 216 on the left and right ends of the movable plate 213 move downward synchronously, and under the action of the gear column 217, the tooth plates 216 on the left and right ends of the mounting plate 211 drive the mounting plate 211 to move upward synchronously along the corresponding guide columns 215, and the flexible tray 212 moves upward synchronously with the mounting plate 211 until the flexible tray 212 conflicts with the lower end surface of the polarizer, and at this time, the flexible ball 214 still maintains support for the polarizer. state, but under the action of the flexible tray 212, the polarizer will no longer move freely along the flexible ball 214. The uniformly arranged flexible tray 212 is used to provide uniform supporting force for the polarizer, which is beneficial to improving the stability of the polarizer, further protecting the polarizer, and ensuring the smooth progress of the subsequent laser cutting. It should be noted that the downward movement distance of the polarizer in this process is short, and the positioning plate 231 and its corresponding elastic rubber pad will not interfere with the downward movement of the polarizer. After the flexible tray 212 contacts the lower end surface of the polarizer, the front and rear side abutment plates 233 can be made to fit with the front and rear ends of the polarizer in the same manner as above, so as to limit and fix the polarizer in the front and rear directions, and center the polarizer, which is beneficial to the precision and accuracy of the subsequent laser cutting and avoids the movement or misalignment of the polarizer during the cutting process. At the same time, it can also reduce the adjustment and correction time during the cutting process and improve production efficiency.

[0052] See also Figure 4 , Figure 5 and Figure 6 The leftmost and rightmost sides away from the mounting plates 211 are both provided with front-to-rear symmetrical arc-shaped support plates 238, which are installed on the upper end of the fixed platform 2. The fixed platform 2 is provided with a material discharge slot which corresponds to the arc-shaped support plate 238 and is located below it, and a protective frame 239 installed on the upper end of the fixed platform 2 is provided on the upper end of the material discharge slot, and a collecting frame 240 placed on the upper end of the base 1 is provided below the material discharge slot.

[0053] While the flexible tray 212 is in contact with the lower end surface of the polarizer, the arc-shaped support plate 238 simultaneously supports the lower end surface of the polarizer. The arc-shaped support plate 238 is located at the cutting angle position corresponding to the polarizer and does not affect the subsequent laser cutting. The arc-shaped support plate 238 can support and protect the polarizer during the laser cutting process to prevent the polarizer from being deformed or broken by the cutting force during the cutting process, thereby increasing the overall quality of the polarizer. During the subsequent laser cutting process, the cut corners fall downward into the protective frame 239, and smoothly pass through the material discharge slot through the protective frame 239, and finally enter the collection frame 240. The cutting waste can be uniformly collected through the collection frame 240 to avoid the cut corners remaining on the upper end of the fixing table 2 and affecting the subsequent centering and cutting of the polarizer. After the collection frame 240 collects a certain amount of waste, it can be taken out from the upper end of the base 1 and the waste inside can be centrally processed.

[0054] See also Figure 2 , Figure 3 , Figure 8 and Fig. 9 The cutting unit 22 includes a vertical guide rail 221 symmetrically mounted on the upper end of the base 1, a support plate 222 is slidably mounted between the front and rear vertical guide rails 221, an electric slider 223 symmetrically mounted on the upper end of the support plate 222 and slidably connected to the corresponding vertical guide rail 221, an arc plate 224 is mounted on both the left and right ends of the support plate 222, an arc through groove 225 is opened on the arc plate 224, a moving block 226 is slidably mounted in the arc through groove 225, and a moving block 226 is arranged at the lower end of the moving block 226 A laser cutting machine 227 is installed, and a square plate 228 is arranged at the lower end of the support plate 222. A flexible pressure block 229 corresponding to the flexible tray 212 is installed at the lower end of the square plate 228. Spring telescopic rods 230 evenly arranged on the left and right are connected between the square plate 228 and the support plate 222. The front and rear guide columns 215 located in the middle are connected to the square plate 228 and the support plate 222 for up and down sliding. A rotating component for driving the left and right laser cutting machines 227 to move synchronously is arranged on the upper end of the support plate 222.

[0055] See also Figure 2 , Figure 3 and Figure 8 The rotating assembly includes a control plate 241 located above the arc plate 224, which is installed at one end close to the left and right moving blocks 226. The ends of the left and right control plates 241 are rotatably connected to the support plate 222. The upper ends of the sides close to the left and right control plates 241 are installed with driven gears 242. A driving gear 243 rotatably connected to the support plate 222 is meshed between the left and right driven gears 242. The upper end of the driving gear 243 is connected to the output shaft of the motor 244, and the motor 244 is installed on the upper end of the support plate 222 through a support.

[0056] After the polarizer is fixed, the front and rear electric sliders 223 can be used to synchronously drive the support plate 222 to move downward along the vertical guide rail 221, and the support plate 222 drives the left and right arc plates 224, the moving block 226, the laser cutting machine 227 and the rotating assembly to move downward synchronously. The square plate 228 and the flexible pressing block 229 move downward synchronously with the support plate 222 through the spring telescopic rod 230. Under the action of the square plate 228 and the support plate 222, the spring telescopic rod 230 gradually contracts, and at the same time, the square plate 228 drives the flexible pressing block 229 to gradually contact the upper end surface of the polarizer, and the flexible pressing blocks 229 arranged evenly are used to apply flexible pressure to the upper end surface of the polarizer, and are used in conjunction with the flexible tray 212 to ensure The polarizer will not shake up and down. It should be noted that the elastic force of the spring telescopic rod 230 is relatively small, and the pressing force applied to the polarizer by the flexible pressing block 229 is relatively small, so as to ensure that the flexible pressing block 229 will not damage the upper end surface of the polarizer while pressing the polarizer. In addition, the front and rear guide columns 215 located in the middle can support and guide the support plate 222 and the square plate 228 when moving downward, so as to increase the stability of the support plate 222 and the square plate 228 during the downward movement, thereby improving the overall stability of the cutting unit 22. In addition, the flexible tray 212, the flexible ball 214, the flexible pressing block 229 and the elastic rubber pad used in the present invention are all made of high temperature resistant materials, and laser cutting will not cause damage to the above parts.

[0057] While the flexible pressing block 229 is pressing the polarizer, the left and right laser cutting machines 227 synchronously reach the appropriate laser cutting angle position. In the initial state, the laser cutting machine 227 on the left is located at the front side of the left curved plate 224, and the laser cutting machine on the right is located at the rear side of the right curved plate 224. Then, the driving gear 243 can be driven by the motor 244 to rotate counterclockwise. While the driving gear 243 rotates, it drives the driven gears 242 on the left and right sides to rotate synchronously in the opposite direction, and the driven gears 242 on the left and right sides keep rotating synchronously clockwise, and the control board 241 rotates with the corresponding The driven gear 242 rotates synchronously clockwise. At the same time, the control board 241 drives the moving block 226 to move synchronously along the arc groove 225. The laser cutting machine 227 moves synchronously along the arc plate 224 with the moving block 226. The arc plate 224 and the arc groove 225 can be used to support and guide the laser cutting machine 227 during the mobile cutting process, thereby increasing the stability of the laser cutting machine 227 and making the laser cutting machines 227 on the left and right sides always maintain the same state. When the laser cutting machine 227 on the left moves to the cutting angle above the front side of the left end of the polarizer, When the laser cutting machine 227 on the right side moves to the cutting position above the rear right end of the polarizer, the laser cutting machines 227 on the left and right sides can cut the polarizer at the same time, and the laser cutting machines 227 are in a moving state during the cutting process. After the cutting of the polarizer in the diagonal direction is completed, the laser cutting machine 227 stops working. With the continuous movement of the laser cutting machines 227 on the left and right sides, the laser cutting machine 227 on the left side gradually reaches the cutting position above the rear left end of the polarizer, and the laser cutting machine 227 on the right side gradually reaches the right end of the polarizer. The cutting position on the upper front side can then be used to cut the remaining corners of the polarizer in the same way to increase the aesthetics of the polarizer and the convenience of installation, while also improving its compatibility with other components. This cutting method can perform synchronous and stable cutting operations on the four corners of the polarizer at one time, reducing the number of operations and time. It not only greatly improves the cutting efficiency, but also ensures that the cutting size and angle of the four corners of the polarizer are consistent, thereby improving the consistency and quality stability of the polarizer after cutting. In addition, laser cutting helps reduce the generation of cutting burrs.

[0058] After the polarizer is cut, the cutting unit 22 can be reset upward in the opposite manner to the above method, so that the cut polarizer is separated from the pressing of the flexible pressing block 229, and then the front and rear side plates 233 can be synchronously moved in the opposite direction to move away from the polarizer, and the moving plate 213 and the mounting plate 211 are reset at the same time, so that the cut polarizer is separated from the flexible tray 212, and then the cut polarizer can be removed (the cut polarizer is as shown in FIG. Fig.10 shown).

[0059] Step 3: Thoroughly clean and purify the laser-cut polarizer using existing technology to remove dust, particles and other contaminants on the surface of the polarizer to improve its optical performance and reliability.

[0060] Step 4: Conduct comprehensive quality inspection on the polarizer through existing testing equipment, such as appearance inspection, optical performance test, mechanical performance test, etc., to ensure that it meets the specified standards and requirements.

[0061] Step 5: Pack the polarizers that have passed the quality inspection with anti-static bags, bubble bags, cartons and other materials to protect them from damage during transportation and storage.
