[0025] For an assembly feeding device provided by an embodiment of the present invention, before feeding a display module to different workstations, first, each carrier on each carrier material tray is grabbed onto an assembly plate through a first transfer structure, realizing convenient transfer of each carrier without manual operation. Then, the display modules on each product material tray are grabbed onto the carriers on the assembly plate through a second transfer structure, realizing convenient transfer of each display module without manual operation. At this time, the PAD points on the PCB board are opposite to the PAD point avoidance areas, and the movable plate is in the second state, that is, the movable plate and the display module are arranged at intervals. Then, the movable plate is driven to move through a driving member, so that the movable plate presses the PCB board of the display module by gravity, and an efficient assembly forms a feeding unit. And at this time, the movable plate is in the first state, so that when feeding to different workstations subsequently, the movable plate will firmly press the display module on the corresponding carrier, ensuring that the display module will not detach from the carrier during the transfer and feeding of the display module. Finally, the carrier of the feeding unit completed with assembly on the assembly plate is transferred back to each carrier material tray through the first transfer structure again. By repeating the above steps, storage of multiple feeding units can be realized through each carrier material tray. During the testing process of the display module at each workstation, unified transfer can be realized through multiple carrier material trays, thereby improving the feeding rate. And at different workstations, only the carriers on each carrier material tray need to be placed on the workstation in sequence, and the PAD points on the PCB board are conducted through the conduction mechanism passing through the PAD point avoidance areas, thereby finally realizing the lighting of the display panel.

[0026] That is to say, an assembly feeding device provided by an embodiment of the present invention can not only conveniently and efficiently complete the assembly of the carrier and the display module, but also realize the storage and transfer of multiple feeding units, and can also avoid the problem that the display module is extremely likely to fall off and be damaged from the carrier during the transfer and feeding of the display module.

[0042] Embodiment:

[0043] Figure 1 is the first view of an assembly feeding device provided by an embodiment of the present invention, Figure 2 is the second view of an assembly feeding device provided by an embodiment of the present invention, combined with Figure 1 and Figure 2As shown, the assembly and feeding device includes a bottom plate 1 and a transfer component 2.

[0044] The bottom plate 1 is provided with an assembly plate 11 (see Figure 3 ), the assembly plate 11 is provided with a driving part 12, a plurality of carrier plate material trays 13 and a plurality of product material trays 14 are placed on the bottom plate 1, and each carrier plate material tray 13 is provided with a plurality of carrier plates 131 arranged at intervals (see Figure 4 ). Each carrier plate 131 is provided with a PAD point avoidance area 1311 and a movable plate 1312. The movable plate 1312 is movably arranged on the carrier plate 131, and the driving part 12 is in transmission connection with the movable plate 1312 to drive the movable plate 1312 to press the PCB board 1412 of the display module 141. Each product material tray 14 is provided with a plurality of display modules 141 arranged at intervals.

[0045] The transfer component 2 includes a first transfer structure 21 and a second transfer structure 22. The first transfer structure 21 can grasp each carrier plate 131 to transfer the carrier plate 131 between the assembly plate 11 and the carrier plate material tray 13, and the second transfer structure 22 can grasp each display module 141 to transfer the display module 141 between the corresponding carrier plate 131 on the assembly plate 11 and the product material tray 14.

[0046] For an assembly loading device provided by an embodiment of the present invention, before loading the display module 141 at different workstations, first, each carrier 131 on each carrier material tray 13 is grabbed by the first transfer structure 21 and placed on the assembly plate 11, realizing the convenient transfer of each carrier 131 without manual operation. Then, the display module 141 on each product material tray 14 is grabbed by the second transfer structure 22 and placed on the carrier 131 of the assembly plate 11, realizing the convenient transfer of each display module 141 without manual operation. At this time, the PAD points on the PCB board 1412 are directly opposite to the PAD point avoidance area 1311, and the movable plate 1312 is in the second state, that is, the movable plate 1312 is arranged at an interval from the display module 141. Then, the driving member 12 is used to drive the movable plate 1312 to move, so that the movable plate 1312 presses the PCB board 1412 of the display module 141 by gravity, and an efficient assembly forms a loading unit. And, at this time, the movable plate 1312 is in the first state, so that when loading at different workstations subsequently, the movable plate 1312 will firmly press the display module 141 on the corresponding carrier 131, so that the display module 141 will not break away from the carrier 131 during the transfer and loading of the display module 141. Finally, the carrier 131 of the loading unit completed on the assembly plate 11 is transferred back to each carrier material tray 13 by the first transfer structure 21 again. Repeat the above steps, so that multiple loading units can be stored through each carrier material tray 13. During the testing process of the display module 141 at each workstation, unified transfer can be realized through multiple carrier material trays 13, thereby improving the loading rate. And, at different workstations, only need to place each carrier 131 on the carrier material tray 13 on the workstation in sequence, and conduct the PAD points on the PCB board 1412 after passing through the PAD point avoidance area 1311 through the conduction mechanism, so as to finally realize the lighting of the display panel 1411.

[0047] That is to say, an assembly loading device provided by an embodiment of the present invention can not only conveniently and efficiently complete the assembly of the carrier 131 and the display module 141, but also realize the storage and transfer of multiple loading units, and can also avoid the problem that the display module 141 is extremely easy to fall off and be damaged from the carrier 131 during the transfer and loading of the display module 141.

[0048] Exemplarily, the number of the movable plates 1312 can be 2, so as to ensure the reliability of the pressing of the PCB board 1412.

[0049] Exemplarily, the carrier 131 has a display panel positioning groove 1317 to position the display panel 1411. The product material tray 14 and the carrier 131 have avoidance holes 1318, which can realize the avoidance of the downward support of the panel tray 225.

[0050] Furthermore, a avoiding groove 1319 is provided on the surface of the movable plate 1312 facing the PCB board 1412 of the display module, and at least one side of the avoiding groove 1319 extends to the edge of the movable plate 1312 to limit the top surface and side edges of the PCB board 1412.

[0051] In the above embodiment, the arrangement of the avoidance groove 1319 can not only realize the pressing of the PCB board 1412, but also realize the limiting of the side of the PCB board 1412, thereby further realizing the positioning of the PCB board 1412.

[0052] Figure 5 is a schematic structural diagram of a first transport structure provided by an embodiment of the present invention, such as Figure 5 As shown, the first transfer structure 21 includes a first bracket 211, a first finger cylinder 212 and two carrier trays 213. The first finger cylinder 212 can be moved along the X-axis, Y-axis or Z-axis directions on the first bracket 211 through a linear module. The first finger cylinder 212 is transmission-connected to the two carrier trays 213 to drive the two carrier trays 213 to move closer or further away.

[0053] In the above embodiment, the position of the first finger cylinder 212 in three-dimensional space can be adjusted by the linear module on the first bracket 211, so that the position of the carrier tray 213 can be adjusted, and then each carrier 131 on each carrier material tray 13 can be grasped in turn.

[0054] Exemplarily, a first connecting plate 214 is provided between the first finger cylinder 212 and the carrier tray 213 , thereby achieving avoidance above the carrier 131 .

[0055] Similarly, both sides of the carrier plate 131 have avoidance grooves, so as to facilitate the loading of the carrier plate 131 after the carrier plate tray 213 is inserted.

[0056] In addition, the first bracket 211 includes a first support rod arranged along the X-axis, a second support rod arranged along the Y-axis, and a third support rod arranged along the Z-axis. Linear modules are respectively arranged on the three support rods. The two opposite support rods are driven by the linear modules, and the first finger cylinder 212 is connected to the linear module on the third support rod, thereby finally realizing the position adjustment of the first finger cylinder 212 in three-dimensional space. In addition, a first camera is arranged on the first bracket 211, which is used to take pictures of the carrier material tray 13 or the assembly plate 11. The first camera transmits the image obtained by the photo to the image processor, and transmits it to the controller after processing. The controller controls the multiple linear modules to perform corresponding displacements, thereby realizing the automatic grasping and placement of the carrier 131 at different positions.

[0057] Exemplarily, the number of the first finger cylinders 212 can be two, and each first finger cylinder 212 corresponds to two carrier trays 213, so as to realize the transfer of two carriers 131 and improve the efficiency.

[0058] Figure 6 FIG. is a schematic structural diagram of a second transfer structure provided by an embodiment of the present invention. As Figure 6 shown, the second transfer structure 22 includes a second bracket 221, a connection block 222, a PCB board suction cup 223, a second finger cylinder 224, and two panel trays 225. The connection block 222 can move along the X-axis, Y-axis, or Z-axis directions on the second bracket 221 through a linear module 161. The PCB board suction cup 223 and the second finger cylinder 224 are arranged at intervals on the connection block 222. The second finger cylinder 224 is in transmission connection with the two panel trays 225 to drive the two panel trays 225 to approach or separate from each other.

[0059] In the above embodiment, the position adjustment of the connection block 222 in the three-dimensional space can be realized through the linear module 161 on the second bracket 221, so that the positions of the PCB board suction cup 223, the second finger cylinder 224, and the two panel trays 225 can be adjusted, and then multiple display panels 1411 on each product material tray 14 in sequence can be grabbed.

[0060] Exemplarily, second connecting plates 226 are respectively arranged at two output ends of the second finger cylinder 224, and the panel trays 225 are connected through the second connecting plates 226, so as to realize the avoidance position above the display panel 1411.

[0061] Exemplarily, by evacuating the air from the PCB board suction cup 223, the adsorption and positioning of the PCB board 1412 can be automatically realized, with high stability and high speed. In addition, the second finger cylinder 224 can drive the two panel trays 225 to approach until the two panel trays 225 move below the display panel 1411 to stably hold the display panel 1411, so as to finally automatically realize the grabbing and transfer of the display module 141 and avoid manual operation.

[0062] In addition, since the display panel 1411 is usually a silicon-based chip (without a glass film attached at this time) and has components on the top surface, the top surface and the side edges of the display panel 1411 cannot be in contact with the outside during the transfer process (to avoid damaging the components). The panel tray 225 only supports the bottom surface of the display panel 1411, and under the adsorption and positioning of the PCB board 1412, during the grabbing and transfer process, the panel tray 225, the second finger cylinder 224, etc. will not contact the top surface and the side edges of the display panel 1411, so as to effectively avoid damaging the display panel 1411. Moreover, through the support of the two panel trays 225, the stability is high and the space utilization rate is high.

[0063] Exemplarily, the second bracket 221 also includes a first rod arranged along the X-axis, a second rod arranged along the Y-axis, and a third rod arranged along the Z-axis. Linear modules are respectively provided on the three rods, and the relative two rods are driven by the linear modules, while the connecting block 222 is drivingly connected to the linear module on the third rod. In addition, a second camera is provided on the second bracket 221 for taking pictures of the product material tray 14 or the carrier plate 131. The second camera transmits the images obtained by taking pictures to the image processor, and after processing, transmits them to the controller, and the controller controls the plurality of linear modules 161 to perform corresponding displacements, so as to realize the automatic grasping and placement of the display modules 141 at different positions.

[0064] Exemplarily, the bottom plate 1 is provided with a plurality of light sources, so as to provide light sources for taking pictures of the first camera or the second camera.

[0065] In this embodiment, the PCB board suction cup 223 can be a bellows suction cup.

[0066] It is easy to understand that the bellows suction cup has a certain flexibility and can expand and contract in the vertical direction, thereby compensating for the height difference in the vertical direction between the bottom surface of the PCB board suction cup 223 required for different display modules 141 and the top surface of the panel tray 225, and increasing the applicable range of the device. In addition, during the process of grasping the display module 141, when the connecting block 222 moves downward, the PCB board suction cup 223 first contacts and compresses the PCB board 1412, and at this time, the PCB board 1412 is adsorbed and will not be damaged by being pressed. Thereafter, the panel tray 225 continues to descend below the display panel 1411, and the second finger cylinder 224 drives the two panel trays 225 to approach (so that the panel trays 225 are located directly below the display panel 1411). Finally, the connecting block 222 moves upward, and the two panel trays 225 respectively support both sides of the bottom surface of the display panel 1411, and the PCB board 1412 is adsorbed by the PCB board suction cup 223, so as to finally complete the grasping of the display module 141.

[0067] Furthermore, each panel tray 225 is respectively provided with a plurality of adsorption holes, and the plurality of adsorption holes of each panel tray 225 are arranged at intervals.

[0068] In the above embodiment, the adsorption and fixation of the display panel 1411 can be realized by evacuating the plurality of adsorption holes, so as to prevent the display panel 1411 from swinging and colliding and being damaged during the transportation process.

[0069] In addition, each carrier plate 131 is provided with a first two-dimensional code, each display module 141 is provided with a second two-dimensional code (not shown in the figure), and the first bracket 211 is provided with a code scanning probe for scanning and associating the first two-dimensional code and the second two-dimensional code.

[0070] Exemplarily, after the display module 141 is pressed on the carrier board 131, the code scanning probe can scan the two-dimensional codes on the carrier board 131 and the corresponding display module 141 respectively, and associate the first two-dimensional code and the second two-dimensional code to form a corresponding relationship, making it more convenient for subsequent management, recording, and querying.

[0071] In other embodiments of the present invention, the first transfer structure 21 and the second transfer structure 22 can also be robotic arms.

[0072] In this embodiment, a waste tray 15 for placing the carrier board 131 is provided on the bottom plate 1. The first transfer structure 21 is configured to transfer the carrier board 131 from the assembly plate 11 to the waste tray 15 when the display module 141 is misaligned on the carrier board 131.

[0073] It is easy to understand that when the display module 141 is misaligned during the placement process on the carrier board 131, the movable plate 1312 is very likely to press on the display panel 1411, resulting in damage to the display panel 1411. Therefore, by providing the waste tray 15, when the display module 141 is misaligned on the carrier board 131, the carrier board 131 can be directly transferred to the waste tray 15, and at this time, there is no need to press the display module 141 anymore.

[0074] In one implementation manner of the present invention, Figure 7 is a schematic structural diagram of the assembly plate provided by the embodiment of the present invention. Combining Figure 4 and Figure 7 as shown, the movable plate 1312 includes a first plate body 1313 and a second plate body 1314 arranged in an L shape. A rotating shaft is inserted at the connection of the first plate body 1313 and the second plate body 1314, and the rotating shaft is rotatably arranged on the carrier board 131. The driving member 12 includes a first cylinder 121, a second cylinder 122, and a driving rod 123. The output shaft of the first cylinder 121 is in transmission connection with the second cylinder 122, and the output shaft of the first cylinder 121 is parallel to the rotating shaft. The output shaft of the second cylinder 122 is perpendicular to the rotating shaft, and the driving rod 123 is perpendicularly connected to the output shaft of the second cylinder 122 to drive the first plate body 1313 or the second plate body 1314 to flip.

[0075] In the above embodiments, by flipping the first plate body 1313 or the second plate body 1314, the movable plate 1312 can be conveniently switched between the first state and the second state. At the same time, by flipping the first plate body 1313 or the second plate body 1314, the flipping of the movable plate 1312 can be conveniently achieved, so as to conveniently press the PCB board 1412. In addition, the first cylinder 121 can drive the driving rod 123 to move left and right, so as to avoid the interference of the driving rod 123 with the picking and placing of the display module 141 on the carrier plate 131. The second cylinder 122 can act on the first plate body 1313 or the second plate body 1314, so as to realize the automatic flipping of the movable plate 1312 without manual flipping.

[0076] Exemplarily, through holes are provided on the assembly plate 11. An installation plate is arranged below the assembly plate 11. The installation plate and the assembly plate 11 are arranged in parallel at intervals, and the installation plate and the assembly plate 11 are connected by columns. The first cylinder 121 is arranged on the installation plate. The output shaft of the first cylinder 121 is connected with a third connecting plate 124. The third connecting plate 124 is of an L-shaped structure. The second cylinder 122 is located on the third connecting plate 124. A fourth connecting plate 125 is installed on the output shaft of the second cylinder 122. The fourth connecting plate 125 passes through the through hole and is in transmission connection with the driving rod 123.

[0077] Exemplarily, the second cylinder 122 can be a finger cylinder, so as to drive the flipping of 2 movable plates 1312 simultaneously.

[0078] Exemplarily, in the initial state, the second plate body 1314 is arranged perpendicular to the carrier plate 131 (the second plate body 1314 is vertical), and the first plate body 1313 is arranged parallel to the carrier plate 131 (at this time, the movable plate 1312 does not press the PCB board 1412, and the driving rod 123 is arranged at intervals from the movable plate 1312). Then, the first cylinder 121 drives the second cylinder 122 and the driving rod 123 to move above the first movable plate 1312, and the second cylinder 122 drives the driving rod 123 to act on the second plate body 1314. The first plate body 1313 rotates to be vertical. At this time, the movable plate 1312 is in the second state. Then, the display module 141 is placed on the carrier plate 131. Finally, the second cylinder 122 drives the driving rod 123 to act on the first plate body 1313, so that the first plate body 1313 rotates to press the PCB board 1412. At this time, the movable plate 1312 is adjusted from the second state to the first state. When the display module 141 needs to be removed, at this time, the second cylinder 122 drives the driving rod 123 to act on the second plate body 1314 again, so that the first plate body 1313 is vertical and separated from the PCB board 1412. At this time, the movable plate 1312 is adjusted from the first state to the second state.

[0079] Furthermore, the carrier plate 131 has two first magnets 1315 arranged at intervals, the first plate body 1313 and the second plate body 1314 have second magnets 1316 respectively, and each second magnet 1316 is arranged opposite to and matched with the corresponding first magnet 1315. The magnetic force generated between the first magnet 1315 and the second magnet 1316 can not only keep the movable plate 1312 in the first state, but also keep it in the second state, thereby preventing the movable plate 1312 from accidentally turning over.

[0080] In another implementation of the present invention, the movable plate 1312 is slidably arranged on the carrier plate 131, and the driving member 12 is a third cylinder, which is transmission-connected to the movable plate 1312 to drive the movable plate 1312 to slide (not shown).

[0081] In the above embodiment, the position of the movable plate 1312 can be easily adjusted by sliding the movable plate 1312 , thereby also realizing convenient conversion of the movable plate 1312 between the first state and the second state.

[0082] Exemplarily, when the movable plate 1312 is in the second state, the display module 141 is placed on the carrier plate 131. Then, the movable plate 1312 is driven to slide by the third cylinder so that the movable plate 1312 is pressed against the PCB board 1412, and the movable plate 1312 is adjusted from the second state to the first state. When the display module 141 needs to be removed, the movable plate 1312 is driven to slide by the third cylinder so that the movable plate 1312 is separated from the PCB board 1412, and the movable plate 1312 is adjusted from the first state to the second state.

[0084] In the above embodiment, the first conveyor line 16 can realize automatic transfer of the carrier material tray 13, thereby realizing automatic loading and unloading of the carrier 131. The second conveyor line 17 can realize automatic transfer of the product material tray 14, thereby realizing automatic loading and unloading of the display module 141.

[0085] Exemplarily, the first conveyor line 16 and the second conveyor line 17 each include a linear module 161, a bracket 162 and two cylinders 163 (see Figure 3) The output end of the linear module 161 drives the bracket 162 to move linearly (the two ends of the linear module 161 can be regarded as the loading port and the unloading port). Two cylinders 163 are arranged at intervals on the bracket 162, and the output ends of the cylinders 163 are drivingly connected to the clamping plates 1631. Thus, the carrier plate material tray 13 or the product material tray 14 is clamped and fixed by the two clamping plates 1631 corresponding to the two cylinders 163, and finally the conveying and displacement are completed under the linear module 161.

[0086] In addition, there is a box body 18 under the bottom plate 1. On one side inside the box body 18, there is a first loading port 181 and a first unloading port 182. Both the first loading port 181 and the first unloading port 182 are provided with a first lifting structure. A plurality of carrier plate material trays 13 are stacked together and are drivingly connected to the output end of the first lifting structure to sequentially lift each carrier plate material tray 13 to the bottom plate 1.

[0087] On the other side inside the box body 18, there is a second loading port 183 and a second unloading port 184. Both the second loading port 183 and the second unloading port 184 are provided with a second lifting structure. A plurality of product material trays 14 are stacked together and are drivingly connected to the output end of the second lifting structure to sequentially lift each product material tray 14 to the bottom plate 1.

[0088] In the above embodiment, by arranging the loading port, the unloading port or the corresponding lifting mechanism inside the box body 18, the carrier plate material tray 13 or the product material tray 14 can be lifted to the bottom plate 1, thereby improving the space utilization rate of the device.

[0089] Exemplarily, two first lifting structures or two second lifting structures are located at both ends of the linear module 161 corresponding to the first conveying line 16 or the second conveying line 17 on the box body 18. Thus, the carrier plate material tray 13 or the product material tray 14 can be sequentially lifted to the bottom plate 1 and then transferred through the first conveying line 16 or the second conveying line 17, and a plurality of carrier plate material trays 13 or a plurality of product material trays 14 can be vertically stacked together to improve the space utilization rate.

[0090] It should be noted that the linear module is a conventional structure in the art, specifically including a motor, a lead screw and a slider. By finally converting the rotation of the motor into the linear motion of the slider, it will not be elaborated here. In addition, the first lifting structure or the second lifting structure can be a stepping motor or a linear module.

[0091] Exemplarily, both the carrier plate material tray 13 and the product material tray 14 are provided with a plurality of positioning grooves arranged at uniform intervals to realize the positioning of the carrier plate 131 or the display panel 1411.

[0092] In other embodiments of the present invention, the first conveying line 16 and the second conveying line 17 can also be conveyor belts, and the present invention does not limit this.
