Abstract
Description
Technical Field
[0001] This utility model relates to the field of polarizer processing technology, specifically to a polarizer sorting and unloading mechanism. Background Technology
[0002] Currently, polarizers are a core optical component of LCD displays, and their production process requires strict sorting, coding, and unloading procedures. Traditional polarizer sorting and unloading processes typically employ manual or single-machine segmented operation modes, such as manual sorting followed by transfer to coding equipment, and then manual unloading. Although some automated sorting mechanisms exist in existing technologies, the following problems still exist:
[0003] The process is decentralized and inefficient: the sorting, coding and unloading processes operate independently and require multiple positioning transfers, resulting in low production efficiency and easy positioning errors;
[0004] Inconvenient waste disposal: Defective products after sorting require manual removal, and the lack of an integrated waste collection module affects continuous production;
[0005] Poor equipment coordination: Existing equipment mostly relies on a single robotic arm or conveyor belt, making it difficult to achieve high-precision multi-station collaborative operation. When the coding and sorting rhythms are not matched, it is easy to cause accumulation or gaps.
[0006] Therefore, there is an urgent need for an integrated, high-precision polarizer sorting and unloading mechanism to solve the problems of multi-process collaboration and automated waste disposal. Summary of the Invention
[0007] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a polarizer sorting and unloading mechanism, which significantly improves production efficiency and automation level through modular design and multi-station collaboration.
[0008] This utility model is achieved through the following technical solution:

The sorting and loading module is used to hold polarizing films to be sorted and drive the polarizing films to move laterally. The multi-axis pickup module is used to pick up the polarizing films from the sorting and loading module and place them in the coding loading module or the waste placement module. The coding loading module is used to drive the polarizing films to the coding module for coding. The coding unloading module is used to transfer and unload the coded polarizing films.
[0010] The sorting and feeding module includes a sorting and feeding linear driver and a sorting and feeding conveyor belt installed at the output end of the sorting and feeding linear driver. The conveying direction of the sorting and feeding conveyor belt is the same as the conveying direction of the inkjet printing module and intersects perpendicularly with the conveying direction of the sorting and feeding linear driver.
[0011] The multi-axis picking module is a spider-hand robot.
[0012] The inkjet printing and feeding module is a conveyor belt.
[0013] The coding module and the coding feeding module are further provided with a coding guide module. The coding guide module includes a coding guide lateral movement mechanism, a first guide lifting mechanism and a second guide lifting mechanism respectively installed at the output end of the coding guide lateral movement mechanism, a first guide plate installed at the output end of the first guide lifting mechanism and a second guide plate installed at the second guide lifting mechanism.

The first guide lifting mechanism is used to drive the first guide plate to move up and down, and the second guide lifting mechanism is used to drive the second guide plate to move up and down.
[0014] The inkjet printing guide transverse movement mechanism includes an inkjet printing drive motor, an inkjet printing slide rail, a first inkjet printing slider, a second inkjet printing slider, an inkjet printing synchronous wheel, and an inkjet printing synchronous belt.
[0015] The inkjet drive motor is driven and connected to the inkjet synchronous wheel via an inkjet synchronous belt. The first inkjet slider is connected to the first guide lifting mechanism and the upper section of the inkjet synchronous belt and is slidably connected to the inkjet slide rail. The second inkjet slider is connected to the second guide lifting mechanism and the lower section of the inkjet synchronous belt and is slidably connected to the inkjet slide rail.
[0016] The beneficial effects of this utility model are:
[0017] The polarizer sorting and unloading mechanism provided by this utility model significantly improves production efficiency by integrating multiple processes such as sorting, coding, and unloading onto a single production line. The mechanism's design allows the polarizer to move laterally within the sorting and loading module, facilitating the rapid and accurate transfer of polarizers from the multi-axis pickup module to the coding and loading module or the waste disposal module. This reduces the need for manual intervention and lowers operational risks. Furthermore, the close integration of the coding and loading module, the coding module, and the coding and unloading module ensures the stability and consistency of the polarizer during the coding process, enabling the efficiently transferred coded polarizers to the next process and further shortening the production cycle.

[0029] Currently, polarizers are the core optical components of LCD displays, and their production process requires strict sorting, coding, and unloading procedures. Traditional polarizer sorting and unloading processes typically employ manual or segmented single-machine operations, such as manual sorting followed by transfer to coding equipment, and then manual unloading. While some automated sorting mechanisms exist in existing technologies, problems remain, including fragmented processes leading to low efficiency, inconvenient waste disposal, and poor equipment coordination.
[0030] To address the aforementioned problems, this embodiment discloses a polarizer sorting and unloading mechanism, the structure of which is as follows: Figure 1 and Figure 2 As shown, the unloading mechanism includes a sorting and loading module 100, a multi-axis pickup module 103, a coding and loading module 104, a coding module 105, a coding and unloading module 106 arranged sequentially along the horizontal direction, and a waste placement module 107 located on one side of the sorting and loading module 100. The sorting and loading module 100 is used to hold the polarizers to be sorted and drive the polarizers to move laterally. The multi-axis pickup module 103 is used to pick up the polarizers from the sorting and loading module 100 and place them in the coding and loading module 104 or the waste placement module 107. The coding and loading module 104 is used to drive the polarizers to the coding module 105 for coding. The coding and unloading module 106 is used to transfer and unload the coded polarizers.
[0031] Furthermore, the sorting and feeding module 100 includes a sorting and feeding linear driver 101 and a sorting and feeding conveyor belt 102 installed at the output end of the sorting and feeding linear driver 101. The conveying direction of the sorting and feeding conveyor belt 102 is the same as the conveying direction of the inkjet printing module 104 and intersects perpendicularly with the conveying direction of the sorting and feeding linear driver 101.
[0032] In this embodiment, the sorting and loading linear drive 101 is preferably a linear motor. The sorting and loading linear drive 101 drives the loading conveyor belt to move laterally to the corresponding position. An external robotic arm places the inspected polarizing film material onto the sorting and loading conveyor belt 102. The sorting and loading linear drive 101 then drives the loading conveyor belt to move laterally to the corresponding position. The multi-axis pickup module picks up the qualified polarizing film and places it into the inkjet printing loading module 104. The sorting and loading linear drive 101 drives the loading conveyor belt to move laterally to the corresponding position, and the multi-axis pickup module picks up the unqualified polarizing film and places it into the waste placement module 107, completing the sorting. Preferably, the multi-axis pickup module 103 is a spider robot, and the inkjet printing loading module 104 is a conveyor belt.
[0033] Furthermore, a coding guide module 200 is provided between the coding module 105 and the coding feeding module 104 to guide the polarizer and prevent material blockage.
[0034] Specifically, the coding guide module 200 includes a coding guide transverse movement mechanism 201, a first guide lifting mechanism 208 and a second guide lifting mechanism 209 respectively installed at the output end of the coding guide transverse movement mechanism 201, a first guide plate 210 installed at the output end of the first guide lifting mechanism 208, and a second guide plate 211 installed at the second guide lifting mechanism 209. The coding guide transverse movement mechanism 201 is used to drive the first guide lifting mechanism 208 and the second guide lifting mechanism 209 to move closer or further away at the same time. The first guide lifting mechanism 208 is used to drive the first guide plate 210 to rise and fall, and the second guide lifting mechanism 209 is used to drive the second guide plate 211 to rise and fall.
[0035] In this embodiment, the first guide lifting mechanism 208 and the second guide lifting mechanism 209 are preferably cylinders.
[0036] Specifically, the inkjet printing guide transverse movement mechanism 201 includes an inkjet printing drive motor 202, an inkjet printing slide rail 203, a first inkjet printing slider 204, a second inkjet printing slider 205, an inkjet printing synchronous wheel 206, and an inkjet printing synchronous belt 207. The inkjet printing drive motor 202 is driven and connected to the inkjet printing synchronous wheel 206 through the inkjet printing synchronous belt 207. The first inkjet printing slider 204 is connected to the first guide lifting mechanism 208 and the upper section of the inkjet printing synchronous belt 207, and is slidably connected to the inkjet printing slide rail 203. The second inkjet printing slider 205 is connected to the second guide lifting mechanism 209 and the lower section of the inkjet printing synchronous belt 207, and is slidably connected to the inkjet printing slide rail 203.
[0037] In this embodiment, when the inkjet printing drive motor 202 is started, the first guide plate 210 and the second guide plate 211 move toward or away from each other to achieve the guiding requirements of polarizers of different sizes and requirements.
[0038] In summary, the polarizer sorting and unloading mechanism provided in this embodiment significantly improves production efficiency by integrating multiple processes such as sorting, coding, and unloading onto a single production line. The design of this mechanism allows the polarizer to move laterally within the sorting and loading module 100, facilitating the rapid and accurate transfer of the polarizer to the coding and loading module 104 or the waste placement module 107 by the multi-axis pickup module 103. This reduces the need for manual intervention and lowers operational risks. Furthermore, the close integration of the coding and loading module 104, the coding module 105, and the coding and unloading module 106 ensures the stability and consistency of the polarizer during the coding process, enabling the efficiently transferred coded polarizer to the next process and further shortening the production cycle.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
