A fixing bracket for a polarizing film box

Abstract

This utility model provides a fixing bracket for a polarizing film cassette, comprising a mounting base and a limiting component connected to the mounting base. The limiting component includes a limiting plate, a support frame, and a stop block. The limiting plate and the support frame are rotatably connected to opposite sides of the mounting surface, and one end of the support frame is slidably connected within the limiting plate. When the limiting plate limits the cassette, rotating it towards the cassette causes the support frame to slide within it. When the limiting plate is in contact with the cassette, the support frame passes through the stop block, which limits the support frame and prevents it from moving. This ensures the limiting plate stably limits the cassette. To release the cassette, pressing the stop block releases its limitation on the support frame. The support frame passes through the stop block, facilitating rotation of the limiting plate and thus accelerating the replacement and fixing of the cassette, thereby increasing production capacity.

Description

Technical Field

[0001] This utility model relates to the field of fixing brackets for polarizer boxes, and particularly to a fixing bracket for polarizer boxes. Background Technology

[0002] As a core optical component of LCD panels, polarizers must be strictly protected from scratches, contamination, or deformation during production, transportation, and assembly. In automated manufacturing processes, polarizers are typically stored in stacks within dedicated cassettes and transferred between processes via robotic arms or conveyor systems. Current technology uses a method to secure the cassettes. In existing technology, after the polarizer cassette is placed on the machine, one side of the cassette is attached to the machine, while the other side is secured with screws. Each time the cassette is changed, the screws must be removed or tightened, reducing processing efficiency.

[0003] Therefore, it is necessary to provide a fixing bracket for the polarizer box to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a fixing bracket for a polarizer box, which solves the problem that in the prior art, the polarizer box needs to be fixed with screws when it is used with the machine, and the screws need to be removed or fixed every time the box is replaced, resulting in low efficiency in changing the box.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a fixing bracket for a polarizing film box, including a mounting base and a limiting component connected to the mounting base. The limiting component includes a limiting plate, a support frame, and a stop block. The limiting plate and the support frame are respectively rotatably connected to both sides of one side of the mounting base. One end of the support frame is slidably connected to the limiting plate. The stop block is connected to the limiting plate to abut against the support frame or to release the limiting of the support frame. When the limiting plate is in contact with the film box, the stop block abuts against the support frame.

[0006] In this utility model, a mounting bracket is provided on one side of the limiting plate, and a first through groove is provided on the side of the mounting bracket away from the support frame. Symmetrical strip-shaped through holes extending along the length direction of the mounting bracket are provided on the sidewalls on both sides of the first through groove.

[0007] The support frame is located in the first through groove and connected to the strip-shaped through hole, and the stop block is connected in the first through groove and located on one side of the strip-shaped through hole.

[0008] In this utility model, the mounting bracket is provided with a first rotating shaft and a second rotating shaft. The first rotating shaft is located in the strip-shaped through hole, and the second rotating shaft is located on one side of the first rotating shaft. The support frame is connected to the first rotating shaft, and the stop block is connected to the second rotating shaft.

[0009] In this utility model, the side of the stop block near the limiting plate is provided with a second through groove extending along the length direction of the stop block;

[0010] An elastic element is provided on the second rotating shaft, and the elastic element is located in the second through groove so that the stop block is reset and engaged with the first rotating shaft.

[0011] In this invention, the thickness of the end of the stop block near the support frame is greater than the thickness of the other end of the support frame.

[0012] In this invention, the mounting base is stepped, and the height of the rotation point of the limiting plate is higher than the height of the rotation point of the support frame.

[0013] In this invention, the mounting base is further provided with a baffle at one end near the bottom of the limiting plate to prevent the limiting plate from rotating.

[0014] In this invention, a fixing seat is also provided at the bottom of the mounting base.

[0015] In this utility model, there are two mounting bases and two limiting components, and the two mounting bases and two limiting components are symmetrically connected to the fixed base.

[0016] In this utility model, the fixed bracket is further provided with a connecting plate, and the two ends of the connecting plate are respectively connected to the tops of the two limiting components.

[0017] Compared with the prior art, the advantages of this utility model are as follows: When the polarizer box fixing bracket of this utility model limits the box by a limiting plate, the limiting plate is rotated toward the box. During the rotation, the limiting plate drives the support frame to slide within the limiting plate. When the limiting plate is in contact with the box, the support frame passes through the stop block, so that the stop block limits the support frame and prevents the support frame from moving. This allows the limiting plate to stably limit the box. When the box is released from the limiting, the stop block is pressed to release the stop block's limitation on the support frame. The support frame passes through the stop block, which facilitates the rotation of the limiting plate, thereby speeding up the efficiency of changing and fixing the box and improving production capacity.

[0032] This utility model provides a fixing bracket for a polarizing film cassette, including a mounting base 11 and a limiting component 13 connected to the mounting base 11. The limiting component 13 includes a limiting plate 131, a support frame 133, and a stop block 134. The limiting plate 131 and the support frame 133 are rotatably connected to both sides of one side of the mounting base 11, respectively. One end of the support frame 133 is slidably connected to the limiting plate 131. The stop block 134 is connected to the limiting plate 131 to abut against the support frame 133 or to release the support frame 133. The limiting plate 131 is positioned so that it abuts against the support frame 133 when it is in contact with the material box. The mounting base 11 is used to install the limiting component 13. The material box is used to hold the polarizer. The limiting component 13 is used to cooperate with the machine tool to fix the material box. When fixing the material box, first, the material box is placed on the machine tool with one side of the material box in contact with the machine tool. The limiting plate 131 is rotated in the direction of the material box. During the rotation of the limiting plate 131, the support frame 133 moves within the limiting plate 131. The support frame 133 passes through... The stop block 134 is positioned so that it abuts against the support frame 133, thereby limiting the support frame 133 and preventing it from moving. Once the support frame 133 is limited, the limiting plate 131 is prevented from moving towards the support frame 133. Since the other side of the limiting plate 131 is in contact with the material box, further movement of the limiting plate 131 towards the material box is prevented, thus securing the material box. When the polarizer in the material box is used up and the material box is replaced, the stop block 134 is pressed down. 34 releases the restriction on the support frame 133, allowing the support frame 133 to move within the inner plate. The limiting plate 131 is moved away from the material box. During the movement of the limiting plate 131, the support frame 133 slides within the limiting plate 131. The support frame 133 releases the restriction on the limiting plate 131, allowing the limiting plate 131 to release the restriction on the material box. When replacing or fixing the material box, there is no need to remove screws or knob screws, effectively improving the efficiency of replacing or fixing the material box and increasing production capacity.

[0033] Please refer to Figure 3 , Figure 3This is a perspective view of the mounting bracket for the polarizer cassette of this utility model. A mounting bracket 132 is provided on one side of the limiting plate 131. A first through groove 1321 is provided on the side of the mounting bracket 132 away from the support bracket 133. Symmetrical strip-shaped through holes 1322 extending along the length of the mounting bracket 132 are provided on the sidewalls of the first through groove 1321. The support bracket 133 is located within the first through groove 1321 and connected to the strip-shaped through holes 1322. A stop block 134 is connected to the first through groove 1321. The mounting bracket 132 is located inside and on one side of the strip-shaped through hole 1322. It is used to install the stop block 134 and the support bracket 133. The support bracket 133 is located inside the first through groove 1321 and connected to the strip-shaped through hole 1322. The support bracket 133 moves along the length of the strip-shaped through hole 1322 to facilitate the rotation of the limiting plate 131. The stop block 134 is connected to the mounting bracket 132 and located on one side of the strip-shaped through hole 1322. It is used to block the support bracket 133 and limit its position.

[0034] The mounting bracket 132 is provided with a first rotating shaft 1323 and a second rotating shaft 1324. The first rotating shaft 1323 is located in the strip-shaped through hole 1322, and the second rotating shaft 1324 is located on one side of the first rotating shaft 1323. The support bracket 133 is connected to the first rotating shaft 1323, and the stop block 134 is connected to the second rotating shaft 1324. The first rotating shaft 1323 is used to facilitate the movement of the support bracket 133 in the strip-shaped through hole 1322, and the second rotating shaft 1324 is used to facilitate the rotation of the stop block 134 on the mounting bracket 132. When the stop block 134 is pressed, it is easy for the stop block 134 to release the restriction on the support bracket 133. After the first rotating shaft 1323 passes through the stop block 134, the stop block 134 limits the first rotating shaft 1323 to prevent the first rotating shaft 1323 from moving in the strip-shaped through hole 1322, thereby fixing the material box with the limiting block.

[0035] The side of the stop block 134 near the limiting plate 131 is provided with a second through groove extending along the length direction of the stop block 134. An elastic element is provided on the second rotating shaft 1324. The elastic element is located in the second through groove so that the stop block 134 resets and engages with the first rotating shaft 1323. The second through groove is used to facilitate the placement of the elastic element. After the stop block 134 is pressed and released, the elastic element can limit the stop block 134, which is convenient for the stop block 134 to limit the support frame 133 next time.

[0036] In this embodiment, the elastic element is a non-circular spring, but it is not limited to using only non-circular springs; it can also be a spring sheet, etc.

[0037] The thickness of the end of the stop block 134 near the support frame 133 is greater than the thickness of the other end of the support frame 133, so as to facilitate the stop block 134 to block the support frame 133 and prevent the stop block 134 from separating from the support frame 133 when the baffle limits the support frame 133.

[0038] The mounting base 11 is stepped, and the height of the rotation point of the limiting plate 131 is higher than the height of the rotation point of the support frame 133, which is used to reduce the length of the support frame 133 and at the same time, facilitates the rotation of the limiting plate 131.

[0039] The mounting base 11 is also provided with a baffle at one end near the bottom of the limiting plate 131 to prevent the limiting plate 131 from rotating. The baffle is used to limit the limiting plate 131 to prevent the limiting plate 131 from rotating too far, which would cause the stop block 134 to fail to stop the support frame 133.

[0040] The bottom of the mounting base 11 is also provided with a fixing base 12, which is used to connect the mounting base 11. At the same time, the mounting base 11 is fixed to the machine base by the fixing base 12.

[0041] There are two mounting bases 11 and two limiting components 13. The two mounting bases 11 and the two limiting components 13 are symmetrically connected to the fixed base 12. The two limiting components 13 can simultaneously limit the two ends of one side of the material box, making the limiting of the material box more stable.

[0042] The fixed bracket is also equipped with a connecting plate, the two ends of which are connected to the top of the two limiting components 13 respectively. The two limiting components 13 are connected together by the connection. When limiting the material box, the two ends on one side of the material box are limited at the same time, which can effectively prevent the material box from shifting position.

[0043] Working principle:

[0044] When limiting the material box, firstly, the two limiting components 13 are assembled on the mounting base 11 respectively, and the two mounting bases 11 are fixed on the fixed base 12 respectively. The fixed base 12 is fixed on the machine platform. When limiting the material box, the material box is placed on the machine platform, and the machine platform fits against one side of the material box to limit one side of the material box. At the same time, the limiting plate 131 is rotated towards the material box. Since one end of the support frame 133 is connected to the strip-shaped through hole 1322 of the mounting frame 132, when the limiting plate 131 moves, the support frame 133 drives the first rotating shaft 1323 to move in the strip-shaped through hole 1322 to facilitate the movement of the limiting plate 131. When the first rotating shaft 1323 contacts and presses the stop block 134, At position 134, the stop block 134 presses against the elastic element, causing the elastic element to deform. After the first rotating shaft 1323 passes through the stop block 134, the elastic element loses the pressing force of the first rotating shaft 1323 and recovers its deformation, which in turn drives the stop block 134 to recover its deformation, thereby limiting the support frame 133 and preventing it from moving. This also limits the material box to the position plate 131. When the material box needs to be replaced, the pressing block is pressed, which presses against the elastic element. The position plate 131 is rotated, causing the first rotating shaft 1323 to pass through the stop block 134, thus releasing the position plate 131 from limiting the material box. With the above structure, it is more convenient to replace and fix the material box, effectively improving the efficiency of replacing and fixing the material box, thereby increasing the processing capacity.

[0045] In this preferred embodiment, when the fixing bracket of the polarizer box limits the box by the limiting plate, the limiting plate is rotated toward the box. During the rotation, the limiting plate drives the support frame to slide within the limiting plate. When the limiting plate is in contact with the box, the support frame passes through the stop block, so that the stop block limits the support frame and prevents the support frame from moving. This allows the limiting plate to stably limit the box. When the box is released from the limiting position, the stop block is pressed to release the stop block's limitation on the support frame. The support frame passes through the stop block, making it easy to rotate the limiting plate, thereby speeding up the efficiency of changing and fixing the box and improving production capacity.

[0046] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
