Fig. 3 is a schematic diagram of a manipulator grabbing a microdisplay assembly according to an embodiment of the invention, and in combination with fig. 1, 2 and 3, when the microdisplay assembly is used, the microdisplay assembly 3 is placed on the microdisplay assembly limiting platform, so that the lighting port 31 is placed in the limiting slot 11 of the first supporting platform 1, and the flexible circuit board 32 passes through the opening of the limiting slot 11, so that the microdisplay 33 is located on the second supporting platform 2. When the micro display assembly 3 is picked up, the manipulator 5 is used for grabbing two sides of the micro display 33 in the width direction, so that the micro display 33 can be grabbed, and then the micro display is moved to the next operation position. In the scheme, the width of the second supporting table 2 is designed to be smaller than the width of the micro display screen 33, so that the second supporting table 2 can not interfere with the grabbing pliers of the manipulator 5 when the manipulator 5 grabs the micro display screen 33, and the manipulator 5 can grab the micro display screen 33 smoothly conveniently. The micro display screen 33 is picked up by the mode that the manipulator 5 grabs, and the grabbing clamp of the manipulator 5 can not touch the display surface of the micro display screen 33, so that the problem that the display effect of the micro display screen in the follow-up use process can be affected due to the fact that a panel (micro display screen) is picked up by the mode that the sucker is used for sucking in the prior art can be avoided.
In addition, the micro display panel assembly 3 in this example includes a panel (micro display panel), an FPC (flexible circuit board), and a lighting port, wherein the panel (micro display panel 33) and the lighting port 31 are connected through the FPC (flexible circuit board 32). The limiting groove 11 for placing the lighting port 31 is arranged on the first supporting table 1, so that the lighting port 31 can be placed conveniently, and the position of the lighting port 31 can be limited. And when the lighting port 31 is placed in the limit groove 11 of the first supporting table 1, the position of the whole micro display screen assembly 3 can be limited, and the displacement of the micro display screen assembly 3 in the transportation process can be prevented from influencing the subsequent grabbing operation. In addition, the problem that the manipulator 5 touches the micro display screen 33 when grabbing the micro display screen 33, so that the micro display screen 33 is displaced, and the grabbing is inaccurate or difficult to grab is avoided.
In this example, the first supporting table 1 and the second supporting table 2 which are connected with each other refer to that the first supporting table 1 and the second supporting table 2 are two independent supporting tables, and are combined together in a connecting manner; the first support table 1 and the second support table 2 which are integrally formed refer to that the first support table 1 and the second support table 2 are integrally manufactured during manufacturing and are connected together.
In some alternative embodiments, the first support table 1 and/or the second support table 2 are provided with a limiting channel 4 for placing the flexible circuit board 32.
In this example, the shape of the limiting channel 4 may be adaptively designed according to the shape of the flexible circuit board 32. In this example, the shape of the flexible circuit board 32 is long, the corresponding limiting channel 4 is also designed to be long, when the flexible circuit board 32 is placed in the limiting channel 4, the position of the limiting channel 4 can be limited, the position of the whole micro display screen assembly 3 is further ensured to be limited, the displacement of the micro display screen assembly 3 in the migration process can be avoided, the subsequent grabbing operation is affected, the micro display screen 33 is prevented from being touched by the manipulator 5 when the micro display screen 33 is grabbed, the micro display screen 33 is enabled to be displaced, and the problem that the micro display screen 33 is difficult to grab is avoided.
In this example, the limiting channel 4 is in communication with the limiting slot 11 through an opening through which the flexible circuit board 32 passes, i.e. in communication with the limiting slot 11. The limiting channel 4 may be disposed on the first support table 1 or the second support table 2, or may be partially disposed on the first support table 1 or partially disposed on the second support table 2 according to the length of the flexible circuit board 32 and the consideration of convenience in processing, so long as the limiting channel 4 communicating with the limiting groove 11 and capable of limiting the position of the flexible circuit board 32 is formed.
In some alternative embodiments, the end of the limiting channel 4 near the location where the micro display screen 33 is placed is provided with an arc opening 41 that flares outwards.
In the present embodiment, when the micro display 33 is gripped by the robot 5, the grippers of the robot 5 need to grip from both sides of the micro display 33. Although the manipulator 5 employs a gripping device with high precision, when the gripper of the manipulator 5 grips the micro display 33, the micro display 33 needs to be contacted from both sides of the micro display 33, and sometimes, gripping inaccuracy may occur. When the time that the tongs of the manipulator 5 contact the two sides of the micro display screen 33 is different, the conditions of asymmetric grabbing force can be caused, namely, the tongs firstly contacting one side of the micro display screen 33 can apply lateral force to the micro display screen 33 in the other direction, the lateral displacement of the micro display screen 33 can be caused, and meanwhile, the flexible circuit board 32 is driven to laterally displace, so that if one end of the limiting channel 4 close to the placing position of the micro display screen 33 is a flush section, the edge of the section can apply shearing force to the flexible circuit board 32 passively, the performance of the flexible circuit board 32 is affected, and if the displacement is large, the flexible circuit board 32 can be damaged.
In this scheme, set up the arc opening 41 that opens to the outside at the one end that spacing passageway 4 is close to micro-display screen 33 and place the position, can be when the tongs of manipulator 5 snatchs micro-display screen 33, when leading to flexible circuit board 32 to produce lateral displacement, avoid spacing passageway 4 to be close to the one end that micro-display screen 33 places the position and can apply the shearing force for flexible circuit board 32 passively, probably damage flexible circuit board 32's problem.
In some alternative embodiments, the height of the bottom surface of the limiting channel 4 is higher than the height of the bottom surface of the limiting groove 11.
In the present embodiment, the height of the bottom surface of the limiting channel 4 is designed to be higher than the height of the bottom surface of the limiting groove 11, so that the lighting port 31 can be limited in the limiting groove 11. In the migration process, if the whole limiting platform is inclined, when the lighting port 31 has a sliding trend towards one side of the limiting channel 4, the bottom surface of the limiting channel 4 is higher than the bottom surface of the limiting groove 11, so that the lighting port 31 can be limited in the limiting groove 11, and the lighting port 31 is prevented from sliding out of the limiting channel 4.
In some alternative embodiments, the width of the restraint channel 4 is less than the width of the restraint slot 11. In the present embodiment, the width of the limiting channel 4 is set smaller than the width of the limiting groove 11, that is, the width of the flexible circuit board 32 is designed smaller than the width of the lighting port 31, so that the lighting port 31 can be limited in the limiting groove 11. In the migration process, if the whole limiting platform is inclined, when the lighting port 31 has a sliding trend towards one side of the limiting channel 4, the width of the limiting channel 4 is designed to be smaller than the width of the limiting groove 11, the lighting port 31 can be limited in the limiting groove 11, and the lighting port 31 is prevented from sliding out of the limiting channel 4.
In some alternative embodiments, the bearing surface of the second supporting platform 2 for placing the micro display screen 33 is on the same horizontal plane with the bottom surface of the limiting channel 4.
In this embodiment, the bearing surface of the second supporting platform 2 for placing the micro display screen 33 is set to be on the same horizontal plane with the bottom surface of the limiting channel 4, so that when the micro display screen assembly 3 moves together with the limiting platform, the micro display screen assembly 3 can slightly displace on the limiting platform, and friction or shearing at the transition between the bearing surface and the limiting channel 4 is avoided, so that the performance of the flexible circuit board 32 is prevented from being affected.
In addition, in the scheme that the end of the limiting channel 4 near the placement position of the micro display screen 33 is provided with the arc opening 41 which is opened outwards, when the grasping forceps of the manipulator 5 grasp the micro display screen 33, the flexible circuit board 32 is enabled to generate lateral displacement, and the problem that the flexible circuit board 32 is possibly damaged due to friction or shearing at the transition part of the bearing surface and the limiting channel 4 is avoided.
In some alternative embodiments, the width of the opening is equal to the width of the limiting channel 4. In this embodiment, the width of the opening where the flexible circuit board 32 passes through and kept by the limiting groove 11 is equal to the width of the limiting channel 4, even if the limiting channel 4 keeps a smooth side wall, the flexible circuit board 32 can be prevented from rubbing or shearing at the transition between the opening and the limiting channel 4 when the micro display screen assembly 3 moves together with the limiting table and the micro display screen assembly 3 moves slightly on the limiting table or when the tongs of the manipulator 5 grasp the micro display screen 33 to make the flexible circuit board 32 move laterally, so that the flexible circuit board 32 may be damaged.
In some alternative embodiments, the limiting groove 11 is square matched with the lighting port 31, and semicircular grooves 12 which are flush with the bottom surface of the limiting groove 11 are arranged at four corners of the square.
In this embodiment, when the limit groove 11 on the first supporting table 1 is manufactured, for convenience of manufacturing, in this example, a mode of milling the limit groove 11 on the first supporting table 1 is adopted, that is, a mode of milling the limit groove 11 by using a rotation of a milling cutter, and since the lighting port 31 in this embodiment is square, the limit groove 11 for limiting the lighting port 31 is also square. When milling square spacing groove 11, in order to mill just the square structure that limit just lights port 31, need all set up the semicircle groove 12 with spacing groove 11 bottom surface parallel and level in square four corners department, conveniently take out the milling cutter to ensure that spacing groove 11 just in time can limit and lights port 31. In addition, the semicircular grooves 12 are arranged at the four corners of the square, so that the lighting ports 31 can be conveniently taken out manually.
Of course, in other embodiments, the method of molding and casting by integral molding is also adopted, so that the semicircular grooves 12 at the four corners of the square shape are not needed.
In some alternative embodiments, when the micro display screen 33 is placed on the second support table 2, both side edges of the second support table 2 are located at least 1mm inside the widthwise edges of the micro display screen 33.
In this embodiment, the edges of the two sides of the second supporting table 2 are at least 1mm inside the edges of the micro display screen 33 in the width direction, so that when the manipulator 5 grabs the micro display screen 33, the second supporting table 2 is ensured not to interfere with the two sides of the grabbing pliers of the manipulator 5, so that the manipulator 5 can grab the micro display screen 33 smoothly, and the grabbing pliers of the manipulator 5 touch the two sides of the micro display screen 33 at the same time as much as possible, so that the micro display screen 33 is prevented from being touched by the manipulator 5 to displace when being grabbed by the manipulator 5.
In some alternative embodiments, the width of the first support table 1 is greater than the width of the second support table 2, and the junction of the first support table 1 and the second support table 2 is rounded.
In this embodiment, the connection between the first support table 1 and the second support table 2 adopts a circular arc chamfering transition mode, which is convenient for processing. Meanwhile, the connection strength between the first supporting table 1 and the second supporting table 2 is also increased, so that the first supporting table 1 or the second supporting table 2 is prevented from being damaged easily when being impacted accidentally.

And the micro display screen 33 is positioned in the middle of the second supporting table 2, so that the subsequent manipulator 5 can be conveniently grabbed.
S2: the manipulator 5 is used to grasp both sides of the micro display 33 in the width direction and move to a predetermined position.
The manipulator 5 is utilized to grasp two sides of the micro display screen 33 in the width direction, and then the manipulator is moved to the next operation position, and as the width of the second supporting table 2 is smaller than the width of the micro display screen 33, the second supporting table 2 can not interfere with the grasping forceps of the manipulator 5 when the manipulator 5 grasps the micro display screen 33, so that the manipulator 5 can grasp the micro display screen 33 smoothly. The micro display screen 33 is picked up by the mode that the manipulator 5 grabs, and the grabbing clamp of the manipulator 5 can not touch the display surface of the micro display screen 33, so that the problem that the display effect of the micro display screen in the follow-up use process can be affected due to the fact that a panel (micro display screen) is picked up by the mode that the sucker is used for sucking in the prior art can be avoided.
