Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid crystal film, and particularly relates to a liquid crystal film initialization system. BACKGROUND

[0002] Before being shipped, liquid crystal films need to be initialized to ensure that the liquid crystal films can be normally used after being shipped, and one of the initialization projects of the liquid crystal films is to power on the liquid crystal films. The existing power-on methods generally adopt two methods. One is single power-on, that is, an operator powers on the liquid crystal films one by one. Although the effect is guaranteed, the work efficiency is low. The other is multiple power-on, that is, an operator powers on multiple liquid crystal films at the same time. Although the work efficiency is improved, the power-on effect is not up to standard or the power-on effect is not up to standard. SUMMARY

[0003] In order to solve the above technical problems, the present application provides a liquid crystal film initialization system, which not only improves the power-on efficiency of the liquid crystal films, but also guarantees the power-on quality of the liquid crystal films.

[0004] In a first aspect, an embodiment of the present application provides a liquid crystal film initialization system, which comprises a first conveying belt, a feeding mechanism, a blackening device and a sorting mechanism. The feeding mechanism is used for placing the liquid crystal films on the first conveying belt one by one, and the liquid crystal films are provided with at least one pair of first electrodes. The blackening device is arranged at a position through which the first conveying belt passes. When the liquid crystal films are conveyed by the first conveying belt to the blackening device, the blackening device makes the pair of first electrodes conductive to make the liquid crystal films power on for initialization. The sorting mechanism is arranged at a position through which the first conveying belt passes. The initialized liquid crystal films are continuously conveyed by the first conveying belt to the sorting mechanism for sorting.

[0005] Further, the blackening device comprises a power supply, a first fixing frame and a pair of second electrodes mounted on the first fixing frame and connected with the power supply. The pair of first electrodes and the pair of second electrodes are in contact for conduction.

[0006] Further, the pair of second electrodes are a pair of elastic sheets respectively.

[0007] Further, the sorting mechanism comprises a detection device and a sorter. The detection device is used for detecting whether the film is successfully initialized. The sorter is used for conveying the liquid crystal films successfully initialized to a first outlet and conveying the liquid crystal films failed in initialization to a second outlet.

[0008] Further, the sorter comprises a baffle arranged on a conveying path of the first conveying belt, which is used for separating the liquid crystal films failed in initialization from the liquid crystal films successfully initialized.

[0009] Furthermore, the baffle is used to prevent the liquid crystal film that failed to initialize from continuing to be conveyed, so that the liquid crystal film that failed to initialize is blocked to the second outlet.

[0010] Furthermore, the detection device includes a first detection device and a second detection device. The first detection device is used to detect liquid crystal films that cannot be initialized; the second detection device is used to detect liquid crystal films with low voltage. The liquid crystal films that cannot be initialized and the liquid crystal films with low voltage are liquid crystal films that have failed to be initialized.

[0011] Furthermore, the liquid crystal film initialization system also includes a storage box, which is used to receive the successfully initialized liquid crystal film and is conveyed to the target position by the first transmission belt.

[0012] Furthermore, the liquid crystal film initialization system also includes a second conveyor belt, which is used to transport the storage box to the first conveyor belt for receiving the liquid crystal film that has been successfully initialized.

[0013] Furthermore, the feeding mechanism includes a paging mechanism, which is used to separate the stacked films into sheets and then feed them to the first conveyor belt.

[0014] As described above, the liquid crystal film initialization system can automatically and in batches power on and detect the liquid crystal films, which not only improves the power-on efficiency of the liquid crystal films, but also ensures the power-on quality of the liquid crystal films.

[0024] Please refer to Figure 1This is a schematic diagram of a liquid crystal film initialization system provided in an embodiment of the present invention. The liquid crystal film initialization system 100 is used to initialize the liquid crystal layer of the liquid crystal film, that is, to energize it so that the liquid crystal film is in a negative state, that is, completely black. A pair of first electrodes 21 are preset at the edge of the liquid crystal film. The liquid crystal film initialization system 100 includes a first conveyor belt 11, a feeding mechanism 12, a blackening removal device 13, a sorting mechanism 14, a storage box 15, and a second conveyor belt 16. The feeding mechanism 12, the first conveyor belt 11, the blackening removal device 13, and the sorting mechanism 14 are sequentially connected as a whole, with the first conveyor belt 11 passing through it. The storage box 15 is placed on the first conveyor belt 11 and the second conveyor belt 16. The downstream part of the first conveyor belt 11 and the upstream part of the second conveyor belt 16 are partially connected, and the second conveyor belt 16 sequentially conveys the storage box 15 to a preset position on the first conveyor belt 11.

[0025] Specifically, such as Figure 1 As shown, according to the present invention, the feeding mechanism 12 is used to place liquid crystal films 200 one by one on the first conveyor belt 11, and the first conveyor belt 11 conveys the received liquid crystal films 200 forward at a uniform speed. Understandably, the feeding mechanism 12 also includes a paging mechanism 121, which is used to separate the stacked liquid crystal films 200 into sheets before sending them to the first conveyor belt 11.

[0026] In this embodiment, the first conveyor belt 11 is double-tracked, meaning it has two parallel conveyor belts extending forward in the same direction. The width of each conveyor belt is precisely matched to the width of each liquid crystal film 200. Simultaneous transport of the liquid crystal films 200 using the double-tracked conveyor belts greatly improves work efficiency. In some embodiments, the first conveyor belt 11 may be made of a material with sufficient flexibility to bend or deform around a core (not shown), such as flexible materials like rubber rings or fabric strips; however, the invention is not limited thereto.

[0027] Please refer to Figure 2This is a schematic diagram of the blackening removal device provided in an embodiment of the present invention. The blackening removal device 13 includes a power supply 131, a first fixing frame 132, and a pair of second electrodes 133. The blackening removal device 13 is positioned along the path of the first conveyor belt 11 and forms a bridge-like structure on the first conveyor belt 11. The first fixing frame 132 is used to fix the second electrodes 133. The second electrodes 133 are in close contact with the first conveyor belt 11 and are respectively connected to the positive and negative terminals of the power supply 131. When the liquid crystal film is conveyed by the first conveyor belt 11 to the contact point of the second electrodes 133, the first electrode 21 contacts the second electrode 133 to complete the energization of the liquid crystal film 200. Understandably, the second electrodes 133 are a pair of elastic sheets. When the liquid crystal film 200 is energized, the elastic function of the second electrodes 133 can maintain a small gap with the liquid crystal film 200, which facilitates the passage of the liquid crystal film 200 and ensures the energization quality of the liquid crystal film 200.

[0028] Please refer to Figure 3 This is a schematic diagram of the sorting mechanism provided in an embodiment of the present invention. The sorting mechanism 14 is used to inspect and sort initialized liquid crystal films 200, and specifically includes a detection device 141 and a sorter 142. The detection device 141 is used to detect whether the liquid crystal film 200 has been successfully initialized, and the sorter 142 is used to transfer successfully initialized liquid crystal films 200 to the first outlet and to transfer uninitialized liquid crystal films 200 to the second outlet.

[0029] Furthermore, the detection device 141 also includes a first detection device 1410 and a second detection device 1411. The first detection device 1410 is used to detect liquid crystal films 200 that cannot be initialized, and the second detection device 1411 is used to detect liquid crystal films 200 with low voltage. Understandably, the uninitialized liquid crystal film 200 refers to the situation where the electrodes of the liquid crystal film 200 have fallen off, and the low-voltage liquid crystal film 200 refers to the situation where the voltage applied to the liquid crystal film 200 is insufficient. Both the uninitialized liquid crystal film 200 and the low-voltage liquid crystal film 200 refer to liquid crystal films 200 that have failed to initialize.

[0030] Please refer to Figure 4This is a functional block diagram of the second detection device provided in an embodiment of the present invention. In some feasible embodiments, for the first case, a color code sensor (not shown) can be installed in the first detection device 1410 to perform color detection on the initialized liquid crystal film 200. Understandably, the color presented by the successfully initialized liquid crystal film 200 is black. When the color code sensor (not shown) detects that the color presented by the initialized liquid crystal film 200 is not the preset color (black), it determines that the liquid crystal film 200 is an initialized liquid crystal film 200 that has failed. For the second case, a low voltage detector 140 and a DC power supply 143 can be installed in the second detection device 1411. First, the voltage of the power supply 143 is adjusted to a preset voltage, such as 40V. Then, a resistor 146 with a preset resistance value, such as 800Ω, is connected in series to the positive terminal of the power supply 143. The other end of the resistor 146 is connected to the positive terminal of the power supply 143. A pair of second electrodes 133 are connected to one end of a pair of first electrodes 21 of the liquid crystal film 200, and the other end of the pair of first electrodes 21 of the liquid crystal film 200 is connected to the negative terminal of the power supply 143. In this way, the resistor 146 is connected in series in the black-out circuit. The resistor 146 limits the current through the liquid crystal film 200. If the liquid crystal film 200 is powered normally, the voltage across the power supply 143 remains unchanged, for example, still 40V. If the voltage across the liquid crystal film 200 is abnormal, the voltage across the power supply 143 will be pulled down, for example, less than 40V. At this time, the low voltage detector 140 is used to detect the duration for which the voltage of the power supply 143 is lower than the preset voltage, for example, the duration for which the voltage of the power supply 143 is lower than the preset voltage. If the duration for which the voltage of the power supply 143 is lower than the preset voltage exceeds the preset time, for example, 30Ms, then the initialization of the liquid crystal film 200 is determined to be a failure.

[0031] Furthermore, the sorter 142 includes a baffle 1420 disposed on the conveying path of the first conveyor belt 11 for separating the liquid crystal film 200 that failed to initialize and the liquid crystal film 200 that successfully initialized.

[0032] Specifically, please refer to the following: Figure 1 When the detection device 141 detects a failed initialization liquid crystal film 200, it will issue an alarm signal and drive a relay (not shown). After the relay (not shown) is activated, it will drive a motor (not shown) to rotate a certain angle, causing the baffle 1420 to rotate as well. Understandably, the baffle 1420 is initially placed flat. Only when the detection device 141 detects a failed initialization liquid crystal film 200 will it drive the relay (not shown) and cause the baffle 1420 to tilt downwards at a certain angle. At this time, the failed initialization liquid crystal film 200 will fall into a preset position through the tilting gap of the baffle 1420.

[0033] Furthermore, the liquid crystal film initialization system 100 also includes a storage box 15 and a second conveyor belt 16. The storage box 15 is used to receive the successfully initialized liquid crystal film 200 and is conveyed to the target position by the first conveyor belt 11. The second conveyor belt 16 is used to convey the empty storage box 15 to the first conveyor belt 11, and the first conveyor belt 11 is used to receive the successfully initialized liquid crystal film 200.

[0034] In some embodiments, the capacity of the container 15 can be preset. For example, it can hold 300 liquid crystal films. In this case, the sorter 142 accumulates the count of the successfully initialized liquid crystal films 200 that have been separated. When the number of successfully initialized liquid crystal films 200 separated reaches the preset number, the second conveyor belt 16 is activated to transport the container 15 to the first conveyor belt 11, thereby realizing automatic switching of the loading port and cargo transportation. The technology of activating the second conveyor belt 16 to transport the container 15 to the first conveyor belt 11 and automatically switching the container 15 and transporting the container 15 full of goods is prior art and will not be described in detail here.

[0035] In the above embodiments, the liquid crystal film initialization system 100 can automatically and in batches initialize the liquid crystal films 200, which not only saves a lot of working time, but also ensures the initialization effect of the liquid crystal films.

[0036] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.

[0037] The above-listed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
