The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic diagram of a first embodiment of a reading apparatus provided in the present application. The reading apparatus 10 of the present embodiment can be used for reading the first mark 1011 and the second mark 1012 on the display panel 101.
Specifically, the reading apparatus 10 of the present embodiment includes two reading mechanisms 11, and the two reading mechanisms 11 are respectively configured to emit light to the first mark 1011 and the second mark 1012 to read the first mark 1011 and the second mark 1012.
Alternatively, each reading mechanism 11 includes an emitting unit 111 and an accepting unit 112, the emitting unit 111 is configured to emit light to the first tag 1011 or the second tag 1012, and the accepting unit 112 is configured to accept the light reflected from the first tag 1011 or the second tag 1012 to read the first tag 1011 or the second tag 1012.
In this embodiment, the receiving unit 112 may be a Charge-Coupled Device (CCD), which is a semiconductor Device and can convert light and electricity, so as to convert an optical image into a digital signal.
Referring to fig. 1 to fig. 2 together, fig. 2 is a schematic view of the display panel 101 in fig. 1 from another viewing angle.
In this embodiment, the display panel 101 includes an upper substrate 1013 and a lower substrate 1014 disposed opposite to each other.
The upper substrate 1013 may be a Color Filter (CF) of the display panel 101, on which the first marker 1011 is disposed; the lower substrate 1014 may be a Thin-Film-Transistor (TFT) of the display panel 101 on which the second mark 1012 is disposed.
Optionally, the number of the first marks 1011 and the second marks 1012 is plural, and in this embodiment, when the first marks 1011 and the second marks 1012 are aligned, the upper substrate 1013 and the lower substrate 1014 can be paired.
Further, the display panel 101 further includes a sealant 1015 disposed between the upper substrate 1013 and the lower substrate 1014, and the sealant 1015 is used for forming one or more spaces for accommodating liquid crystal between the upper substrate 1013 and the lower substrate 1014.
Specifically, in the manufacturing process of the display panel 101, the glue frame 1015 is coated on the lower substrate 1014, liquid crystal is injected into one or more areas surrounded by the glue frame 1015, and then the upper substrate 1013 is covered on the glue frame 1015 according to the first mark 1011 and the second mark 1012, so as to achieve the purpose of sealing the liquid crystal.
However, as the size of the display panel 101 is larger and larger, the structural design is more and more dense, so that the space left for the first mark 1011 and the second mark 1012 on the display panel 101 is smaller and smaller, and thus, in the manufacturing process of the display panel 101, the first mark 1011 or the second mark 1012 is easily interfered with the rubber frame 1015, and the like.
Referring to fig. 1 to 3 together, fig. 3 is a schematic diagram illustrating the interference between the first mark 1011 or the second mark 1012 and the plastic frame 1015 in fig. 2.
Since the manufacturing of the display panel 101 is a complicated process, multiple processes are often involved, the same mark on the display panel 101 may be used as a processing reference for the multiple processes, and if the first mark 1011 or the second mark 1012 interferes with the rubber frame 1015, the reading and the use of the first mark 1011 or the second mark 1012 by the subsequent processes are affected, so that the normal operation of the subsequent processes is affected. For this reason, when the first mark 1011 cannot be read by a subsequent process, the second mark 1012 needs to be selectively read; or when the second mark 1012 cannot be read by a subsequent process, the first mark 1011 is selectively read.
In this embodiment, the reading apparatus 10 is configured to, when the projection of the glue frame 1015 on the upper substrate 1013 at least partially overlaps the first mark 1011, read the second mark 1012 by the other of the two reading mechanisms 11; or the projection of the glue frame 1015 on the lower substrate 1014 at least partially coincides with the second indicia 1012, one of the two reading mechanisms 11 reads the first indicia 1011.
Specifically, the reading apparatus 10 further includes a reflection mechanism 12, one of two reading mechanisms 11 is disposed on a side of the upper substrate 1013 away from the lower substrate 1014, and emits light to the first marker 1011 in a direction perpendicular to the upper substrate 1013 to read the first marker 1011; the other of the two reading mechanisms 11 is disposed on a side of the upper substrate 1013 away from the lower substrate 1014 and emits light toward the second mark 1012 in a direction perpendicular to the lower substrate 1014, and the reflection mechanism 12 is configured to reflect the light emitted by the other of the reading mechanisms 11 to the second mark 1012 to read the second mark 1012. In this way, when the first marker 1011 can be read, the first marker 1011 is directly read by one of the two reading mechanisms 11; when the first mark 1011 interferes with the rubber frame 1015 and cannot be read, the second mark 1012 is read by the cooperation of the other of the two reading mechanisms 11 and the reflection mechanism 12, so that the display panel 101 does not need to be turned over, and the influence of the turning over on the quality of the display panel 101 is avoided.
Alternatively, the reflection mechanism 12 may be movable relative to the display panel 101 to adjust the position of the reflection mechanism 12 according to the position of the second mark 1012 on the lower substrate 1014, so that the reflection mechanism 12 can reflect light emitted from another one of the reading mechanisms 11 to the second mark 1012, thereby reading the second mark 1012.
Alternatively, the reflection mechanism 12 includes two reflection units 121, and the two reflection units 121 are symmetrically disposed so that the light received by the second mark 1012 is parallel to the light emitted by the other of the two reading mechanisms 11.

Optionally, the bracket 13 is provided with an accommodating space 131, and the reflection mechanism 12 is movably connected with the bracket 13 to accommodate or extend out of the accommodating space 131.
In this embodiment, the reflection mechanism 12 is located below the display panel 101, and the two reflection units 121 are disposed in a V shape facing the display panel 101, so that dust, water stain, and the like in the production operation easily contaminate the reflection mechanism 12, which results in a deterioration of the reading effect of the reading apparatus 10. Therefore, the reflection mechanism 12 is movably connected with the bracket 13 to be accommodated in the accommodating space 131 when not in use, so that pollution of dust, water stain and the like to the reflection mechanism 12 can be reduced, the reading effect of the reading device 10 is increased, and the efficiency of production operation is improved.
Optionally, at least one of the two reading mechanisms 11 is movably connected to the bracket 13, so as to adjust the position of at least one of the two reading mechanisms 11 according to the position of the first mark 1011 and/or the second mark 1012, so as to meet the reading requirements of the display panels 101 with different dimensions on the first mark 1011 and/or the second mark 1012 in the production operation, thereby increasing the applicable range of the reading device 10.
Referring to fig. 1-4 together, fig. 4 is a schematic diagram of another embodiment of the reflection mechanism 12 in fig. 1. In this other embodiment, the reflection mechanism 12 includes one reflection unit 121, and one reflection unit 121 makes the light received by the second mark 1012 perpendicular to the light emitted from the other of the two reading mechanisms 11.

Other structures in this embodiment are the same as those in the first embodiment of the reading apparatus 10, and are not described herein again.
In this embodiment, a reading mechanism 21 can be disposed on a side of the upper substrate 1013 away from the lower substrate 1014 and emit light to the first marker 1011 or the second marker 1012 in a direction perpendicular to the upper substrate 1013 to read the first marker 1011 or the second marker 1012.
Specifically, one reading mechanism 21 is movably connected to the bracket 13 to move in a direction parallel to the display panel 101, and when it is desired to read the first mark 1011, the one reading mechanism 21 moves to a first position, as shown by a solid line in fig. 5, and emits light toward the first mark 1011 to read the first mark 1011; when it is desired to read the second mark 1012, one of the reading mechanisms 21 is moved to a second position, as shown by the dotted line in fig. 5, and emits light toward the second mark 1012, and the reflecting mechanism 12 reflects the light emitted from one of the reading mechanisms 21 toward the second mark 1012 to read the second mark 1012.
