The key components of the automatic processing equipment for the light incident end face of the light guide plate provided by the invention are described in detail below.
Automatic material taking unit 1
With continued reference to fig. 1 to 2, the automatic material taking unit 1 is used for conveying a single light guide plate to the next processing station (automatic processing unit 2), and includes a storage rack 10 and a material taking device 20, and the material taking device 20 automatically takes out a light guide plate from the storage rack 10 and conveys the light guide plate to the next processing station.
As shown in fig. 3, the magazine 10 is used for storing a plurality of light guide plates, and includes a platform 11 for placing the light guide plates, a plurality of vertically arranged baffles 12 penetrating through the platform 11, the platform 11 and the plurality of baffles 12 surround to form a vertical magazine, the light guide plates are stacked in the magazine, and the light guide plate at the uppermost portion of the magazine can be removed.
In a preferred embodiment, the platform 11 for placing the sheet material is an automatic lifting platform, and the storage rack 10 further includes a detection device and a platform lifting driving device for driving the automatic lifting platform 11 to move up and down along the baffle 12. The automatic lifting platform can move up and down along the baffle 12 under the driving of the platform lifting driving device, and after the automatic lifting platform moves down, the upper part of the storage rack 10 can leave a space for the material taking device 20 to drive the adsorbed plate to vibrate up and down. When the automatic lifting platform moves upwards, the uppermost plate in the storage rack 10 is located at the material taking position 13 of the storage rack 10, and the plate located at the material taking position 13 can be adsorbed and taken away by the material taking device 20.
In another preferred embodiment, the storage rack 10 can store boards with different sizes, and includes a platform 11 for placing boards, a plurality of vertically arranged baffles 12 penetrating through the platform 11, and at least one first guide rail located at the bottom of the storage rack 10, where the baffles 12 arranged at the bottom on the first guide rail are the first baffles, the platform 11 includes first through holes matching the number of the first guide rail, and the first baffles can move back and forth along the first guide rail through the first through holes of the platform 11, so as to change the size of the storage cavity capable of storing boards, and store boards with different sizes.

With continued reference to fig. 3, the extracting device 20 is used to extract a light guide plate from the magazine 10 and convey the light guide plate to the next processing station. The material taking device 20 comprises a mechanical arm 21 and at least one holding part 22 connected with the end of the mechanical arm 21, wherein the mechanical arm 21 can drive the holding part 22 to reciprocate between the storage rack 10 and the next processing station (to-be-processed station 30). The holding part 22 can adsorb and release one surface of the light guide plate. When the mechanical arm 21 drives the holding portion 22 to move from the next processing station to the storage rack 10, the holding portion 22 adsorbs a light guide plate from the storage rack 10, and then the mechanical arm 21 drives the holding portion 22 adsorbed with the light guide plate to move from the storage rack 10 to the next processing station, and the holding portion 22 releases the adsorbed light guide plate to the next processing station.
It should be noted that, the plurality of light guide plates are closely stacked together, and a vacuum connection area is easily existed between the light guide plates, so that the adhesion force between the light guide plates is very large due to the action of the atmospheric pressure, and the plurality of light guide plates adhered together are easily taken out when the holding portion 22 adsorbs the light guide plates from the storage rack 10. In order to increase the probability that the material taking device 20 takes only one light guide plate at a time, in a preferred embodiment, as shown in fig. 3, the material taking device 20 includes two sets of holding parts, namely a first set of holding parts 22.1 and a second set of holding parts 22.2, each set of holding parts includes at least one holding part, and the two sets of holding parts can vibrate in opposite directions in the vertical direction (for example, while the first set of holding parts 22.1 moves up/down, the second set of holding parts 22.2 moves down/up). When the two sets of holding parts of the material taking device 20 adsorb the light guide plate and the two sets of holding parts drive at least two parts of the light guide plate to move in opposite directions in the vertical direction, the opposite movement of the different parts of the light guide plate helps the air to enter the vacuum connection area between the adsorbed light guide plate and other light guide plates, so that the adhesion between the adsorbed light guide plate and other light guide plates caused by the atmospheric pressure is reduced.
Referring to fig. 3 to 4, in a specific embodiment, the light guide plate is rectangular and has A, B, C, D four corners, a connecting line of the two AC corners intersects a connecting line of the two BD corners, the material taking device 20 includes two sets of holding portions, each set of holding portion includes at least two holding portions, a first set of holding portions 22.1 adsorbs the two AC corners of the light guide plate, and a second set of holding portions 22.2 adsorbs the two BD corners of the light guide plate, so that when the two sets of holding portions vibrate in opposite directions in a vertical direction, the adsorbed AC corners of the light guide plate and BD corners vibrate in opposite directions in the vertical direction. That is, when the first set of holding parts 22.1 adsorbed on the corner of the light guide plate AC moves upward, the second set of holding parts 22.2 adsorbed on the corner of the light guide plate BD moves downward; when the first set of holders 22.1 attached to the corner of the light guide plate AC moves downward, the second set of holders 22.2 attached to the corner of the light guide plate BD moves upward.
Referring to fig. 3, in an embodiment, the holding portion 22 is a vacuum chuck, and the specific structure and principle of the vacuum chuck are the prior art and are not described herein again. In other embodiments, the holding portion may be other devices capable of adsorbing the light guide plate.
In order to further improve the probability that the material taking device 20 takes only one light guide plate at a time, in a preferred embodiment, the material taking device 20 further includes at least one blowing device 14, as shown in fig. 3, when two sets of holding parts of the material taking device 20 drive at least two parts of the light guide plate to vibrate in opposite directions in the vertical direction, wind energy blown by the blowing device 14 can more rapidly enter a vacuum connection area between the adsorbed light guide plate and other light guide plates, so as to separate the light guide plate adsorbed by the holding part of the material taking device 20 from other light guide plates.
The following is a material taking process of the automatic material taking unit 1: the material taking device 20 adsorbs and fixes the plate on the top of the storage rack 10, and drives the plate to vibrate for N times, so as to ensure that the material taking device 20 adsorbs only one plate. The extracting device 20 then conveys the adsorbed single light guide plate to the next processing station. When the material taking device 20 adsorbs and fixes the plate on the uppermost portion of the storage rack 10, the automatic lifting platform of the storage rack 10 moves downward for a certain distance, so that a space for the material taking device 20 to drive the adsorbed plate to vibrate is reserved on the upper portion of the storage rack 10. After the material taking device 20 conveys the adsorbed single light guide plate to the next processing station, the automatic lifting platform of the storage rack 10 moves upwards to ensure that the uppermost plate in the storage rack 10 is located at the material taking position 13 of the storage rack 10, and the plate located at the material taking position 13 can be adsorbed and taken away by the material taking device 20.
It should be noted that, the automatic material taking unit 1 and the material taking device 20 of the automatic processing equipment for the light incident end surface of the light guide plate of the present invention are not only suitable for the automatic material taking of the automatic processing equipment for the light incident end surface of the light guide plate of the present invention, but also suitable for other automatic equipments which need to automatically take only one sheet of sheet material.
With continued reference to fig. 1-2, the automatic processing unit 2 is used for automatically performing light-incident end surface processing on a single light guide plate, and includes a station 30 to be processed, a conveying device 40, a light guide plate positioning and fixing device 50, and a processing device 60. Wherein, the single light guide plate conveyed from the previous processing station (automatic material taking unit 1) is placed on the station 30 to be processed, and the single light guide plate waits for the conveying device 40 to convey the single light guide plate to the light guide plate positioning and fixing device 50 at the station 30 to be processed to perform hot stamping processing on the light incident end face of the light guide plate; the conveying device 40 conveys the single light guide plate placed at the station 30 to be processed to the light guide plate positioning and fixing device 50; the light guide plate positioning and fixing device 50 is used for placing the light guide plate at a designated position and fixing the light guide plate, and in the light guide plate positioning and fixing device 50, the processing device 60 performs processing (hot embossing processing) on the light incident end surface of the light guide plate.

The pressing device 52 is used for fixing the light guide plate located in the light guide plate positioning and fixing device 50, so that the processing device 60 processes the light guide plate. The pressing device 52 can reciprocate between a pressing execution position and a pressing release position along the vertical direction, when the pressing device 52 is located at the pressing execution position, the light guide plate is fixed on the workbench 51, and the processing device 60 can process the light incident end face of the light guide plate fixed on the workbench 51; when the pressing device 52 is located at the pressing release position, the light guide plate can be transferred to/from the table 51 of the light guide plate positioning fixture 50.
Preferably, the lower surface of the pressing device has an adsorption function (for example, the lower surface has fine pores capable of forming a negative pressure) so as to adsorb/release the light guide plate. When the pressing device 52 moves from the pressing execution position to the pressing release position in the vertical direction, the lower surface of the pressing device 52 can absorb the light guide plate, and the light guide plate moves from the pressing execution position to the pressing release position along with the pressing device 52. At this time, the work table 51 is in an idle state, and can continuously receive the light guide plate conveyed from the station 30 to be processed, thereby improving the work efficiency of the entire automatic processing unit 2 and the entire apparatus.

The transverse processing rail 63 is parallel to the light incident end face of the light guide plate, and the longitudinal processing rail 62 is perpendicular to the light incident end face of the light guide plate. The hot embossing roller 61 is located on the same horizontal plane as the light guide plate placed on the work table 51. The hot-embossing roller 61 is capable of reciprocating between an initial position and an end position along the machining-transverse rail 63, and the hot-embossing roller 61 is capable of reciprocating between a machining-execution position and a machining-release position along the machining-longitudinal rail 62. While the light guide plate is fixed on the table 51 of the light guide plate positioning fixture 50, the hot-embossing roller 61 is moved to the processing execution position along the processing longitudinal rail 62, and the hot-embossing roller 61 is moved to the initial position along the processing transverse rail 63 (or the hot-embossing roller 61 is located at the processing execution position of the processing longitudinal rail 62 and at the initial position of the processing transverse rail 63); then, the hot embossing roller 61 moves along the processing transverse rail 63 from the initial position to the end position, at this time, the hot embossing roller 61 contacts with the light incident end surface of the light guide plate, and the hot embossing roller 61 rolls to perform hot embossing treatment on the light incident end surface of the light guide plate. After the hot embossing is completed, the hot embossing roller 61 is moved along the processing longitudinal rails 62 to a processing release position, and then the hot embossing roller 61 is moved along the processing transverse rails 63 from an end position to an initial position.
It should be noted that the distance between the initial position and the end position of the transverse processing rail 63 may be greater than or equal to the width of the light incident end surface of the light guide plate, so as to ensure that the hot embossing roller 61 processes the whole light incident end surface. Of course, the distance between the initial position and the end position of the transverse processing track 63 may be smaller than the width of the light incident end surface of the light guide plate, and this case is suitable for the case where only a part of the light incident end surface of the light guide plate needs to be processed. The following is a process of the automatic processing unit 2 described above: the light guide plate at the station 30 to be processed is pushed by the transfer arm 41 along the light guide plate rail 43 to the table 51 of the light guide plate positioning and fixing device 50, while the positioning columns 53 at the side of the table 51 are at the positioning execution position, and the light guide plate is precisely transferred by the transfer arm 41 to the fixed position of the table 51 of the light guide plate positioning and fixing device 50 under the blocking of the positioning columns 53. Then, the pressing device 52 is moved in the vertical direction from the pressing release position to the pressing execution position, and the light guide plate is fixed to the table 51. Subsequently, the positioning column 53 is moved in the vertical direction from the positioning performing position to the positioning releasing position. The hot-embossing roller 61, which has been moved to the initial position of the processing transverse rail 63 and the processing execution position of the processing longitudinal rail 62, is moved from the initial position of the processing transverse rail 63 to the end position, and this moving process is a process of the processing device 60 processing the light-incident end surface of the light guide plate. The hot embossing roller 61 is then moved along the longitudinal processing rail 62 from the processing executing position to the processing releasing position, and then moved along the transverse processing rail 63 from the ending position to the initial position, the pressing device 52 is moved in the vertical direction from the pressing executing position to the pressing releasing position, the positioning post 53 is moved in the vertical direction from the positioning releasing position to the positioning executing position, the light guide plate located in the light guide plate positioning and fixing device 50 waits to be removed, after the light guide plate is removed, the transfer arm 41 transports the next light guide plate, and the above actions are repeated.
It should be noted that the automatic processing unit 2 and the light guide plate positioning and fixing device 50 of the automatic processing device for light incident end surface of light guide plate of the present invention are not only suitable for the automatic processing device for light incident end surface of light guide plate of the present invention to automatically process the light incident end surface of light guide plate, but also suitable for other automatic devices that need to automatically process the end surface of sheet-like plate. The processing apparatus 60 of the present invention may be any other apparatus capable of processing the end face of a sheet-like plate material according to the related art.
Automatic receiving unit 3
With continued reference to fig. 1 to 2, the automatic material receiving unit 3 is used for automatically collecting the light guide plates processed at the previous processing station (the automatic processing unit 2), and includes a material receiving device 70 and a material receiving station 80. The material receiving device 70 transports the light guide plate processed at the previous processing station (the automatic processing unit 2) from the light guide plate positioning and fixing device 50 to the material receiving station 80. The receiving station 80 is used for storing the processed light guide plate.
Referring to fig. 8 to 10, the material receiving device 70 includes at least one robot portion 71 and a robot portion transverse rail 73 for the robot portion 71 to reciprocate between the light guide plate positioning and fixing device 50 and the material receiving station 80, the robot portion 71 is used for clamping or releasing the light guide plate, when the manipulator part 71 moves to or is located at the light guide plate positioning and fixing device 50, the manipulator part 71 can clamp the light guide plate located at the working table 51 of the light guide plate positioning and fixing device 50 (in a preferred embodiment, the manipulator part 71 can clamp the light guide plate located at the lower surface of the pressing device 52, and the manipulator part 71 is not located on the same horizontal plane with the conveying device 40, so that the working efficiency of the whole device can be improved), and moves to the receiving station 80 along the robot hand transverse rail 73, and then the robot hand 71 releases the light guide plate to the receiving station 80.
Referring to fig. 8 to 10, in a specific embodiment, the material receiving device 70 includes two robot portions 71, and a blocking portion 72 is further disposed between the two robot portions 71. The two manipulator portions 71 share a manipulator portion transverse rail 73, and move back and forth between the light guide plate positioning and fixing device 50 and the material receiving station 80. Each of the hand sections 71 is provided with a hand section longitudinal rail along which the hand section 71 reciprocates between the gripping execution position and the gripping release position. When the manipulator 71 moves to or is located at the light guide plate positioning and fixing device 50, the two manipulator 71 move from the clamping release position to the clamping execution position along the manipulator longitudinal track, and clamp the light guide plate located at the light guide plate positioning and fixing device 50. When the manipulator 71 clamps the light guide plate and moves to the receiving station 80 along the manipulator transverse rail 73, the two manipulators 71 release the light guide plate and move from the clamping execution position to the clamping release position along the manipulator longitudinal rail, and at this time, due to the existence of the blocking portion 72 in the middle of the two manipulators 71, the light guide plate does not move from the clamping execution position to the clamping release position along with the manipulator 71.
The receiving station 80 includes at least one receiving bin 81, and the receiving device 70 transports the light guide plate processed by the previous processing station (automatic processing unit 2) from the light guide plate positioning and fixing device 50 to the receiving bin 81 of the receiving station 80.
Referring to fig. 9 and 10, in order to increase the number of light guide plates received by the receiving station 80, in a preferred embodiment, the receiving station 80 includes two receiving bins 81 located on the same receiving rail 83, after the receiving bin 81 located at the receiving station 84 is filled with light guide plates, the receiving bin 81 moves out of the receiving station along the receiving rail 83, and another receiving bin 81 moves to the receiving station 84 along the receiving rail 83 to receive the light guide plates conveyed by the receiving device 70.
When the receiving device 70 releases the light guide plate to the receiving station 80, the light guide plate may be dislocated due to the air resistance when moving in a free-fall manner, so that the released light guide plate does not fall into the receiving bin 81. With continued reference to fig. 9 and 10, in another preferred embodiment, the receiving station 80 further includes a misalignment-preventing calibrating portion 82, when the receiving device 70 releases the light guide plate to the receiving station 80, one side of the released light guide plate away from the receiving device 70 first contacts the misalignment-preventing calibrating portion 82, the misalignment-preventing calibrating portion 82 blocks the side of the released light guide plate (the side away from the receiving device 70) from freely falling downward, and at this time, the other side of the released light guide plate (the side close to the receiving device 70) freely falls, so as to drive the whole released light guide plate to tilt downward to freely fall, and then fall into the receiving bin 81. Since the air resistance is reduced when the released light guide plate is inclined downward, the probability that the released light guide plate directly falls into the receiving bin 81 is increased, and the probability can almost reach 100%.
It should be noted that the automatic material taking unit 1 of the automatic processing equipment for the light incident end face of the light guide plate is not only suitable for the automatic material receiving of the automatic processing equipment for the light incident end face of the light guide plate, but also suitable for other automatic equipment which needs to automatically collect sheet-shaped plates together.
In addition, the automatic processing equipment for the light incident end face of the light guide plate and each part thereof are not only suitable for the light guide plate, but also suitable for other sheet-shaped plates of which the end faces need special treatment, and the end faces to be processed of the plates are suitable for the light incident end face of the light guide plate.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
