Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of LED production, specifically relates to a LED automatic plate collecting machine. BACKGROUND

[0002] In the production and manufacturing process of the LED plate, after the manufacturing of the LED plate is completed, the LED plate needs to be stored in a special tray, the tray is designed with a containing groove suitable for the size and shape of the LED plate, which can ensure that the LED plate will not be damaged by knocking, so as to facilitate the subsequent storage, transportation and distribution of the LED plate.

[0003] At present, the storage process of the LED plate into the tray is mainly completed by the plate collecting machine. The plate collecting machine can accurately grasp and place the LED plate to the predetermined position in the tray, thereby completing the storage work of the LED plate. Although the plate collecting machine has achieved remarkable results in the storage of the LED plate, the degree of automation of the tray stacking and discharging link still needs to be improved.

[0004] After the LED plate is successfully stored in the tray, the existing plate collecting machine often cannot directly perform the stacking operation of the tray, and still needs to rely on manual or simple auxiliary tools to complete. The worker needs to manually take down the tray full of LED plates from the plate collecting machine, and then stack them one by one on the forklift, trolley and other tools, and then push the whole into the warehouse for storage. This manual stacking and discharging method not only consumes a lot of human resources and increases the labor cost of the enterprise, but also is difficult to meet the demand of rapid turnover and large-scale storage, and there is a safety hazard. The worker may be tired, inattentive and other factors, resulting in uneven stacking, tilting or even falling risk, which threatens the safety of the LED plate and may cause product damage or personal injury.

[0005] Therefore, in order to overcome the limitations of the existing plate collecting machine in the tray stacking and discharging link and improve the automation level of the LED plate production process, it is particularly important to develop a new type of LED automatic plate collecting machine.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] The utility model provides an automatic LED board collecting machine, which is used to solve the problem of how to automatically collect, stack and unload LED boards 7 and material trays 3.

[0048] See Figure 1 As shown, Figure 1 3D is a three-dimensional diagram of the LED automatic board collecting machine in the embodiment, which includes a frame 1, an LED board conveying device 2, a tray conveying device 4, a board collecting and stacking device 5 and a material unloading device 6.

[0049] The frame 1 is provided with a first loading station 11 , a second loading station 12 and a board collecting station 13 .

[0050] The LED board conveying device 2 is installed on the frame 1 , and the LED board conveying device 2 is used to convey the LED board 7 to the first loading station 11 .

[0051] The tray conveying device 4 is mounted on the frame 1 and is used to convey the empty tray 3 to the second loading station 12. The tray 3 has a receiving slot 31 for receiving the LED board 7.

[0052] The board collecting and stacking device 5 is installed on the frame 1. The board collecting and stacking device 5 is used to grab the material tray 3 of the second loading station 12 and stack it on the board collecting station 13, and grab the LED board 7 of the first loading station 11 and transfer it to the receiving groove 31 of the material tray 3 of the board collecting station 13.

[0053] The unloading device 6 is installed on the frame 1 and opposite to the plate collecting station 13, and is used to move the full tray 3 loaded with LED plates 7 out of the plate collecting and stacking device 5.

[0054] When the LED automatic plate collecting machine is used, first, the LED plate conveying device 2 conveys the LED plate 7 to the first feeding station 11, and the tray conveying device 4 conveys the empty tray 3 to the second feeding station 12; then, the plate collecting and stacking device 5 grabs the empty tray 3 at the second feeding station 12 and places it on the plate collecting station 13, and then grabs the LED plate 7 at the first feeding station 11 and transfers it into the containing groove 31 of the tray 3 at the plate collecting station 13, so as to complete the automatic storage of the LED plate 7 into the tray 3; after the tray 3 is full of the LED plates 7, the plate collecting and stacking device 5 drives the full tray 3 loaded with the LED plates 7 to move down by one height of the tray 3, so as to move the full tray 3 loaded with the LED plates 7 out of the plate collecting station 13; then, after the above-mentioned feeding actions of the LED plate 7 and the tray 3 are repeated again, the plate collecting and stacking device 5 grabs the empty tray 3 at the second feeding station 12 again and places it on the plate collecting station 13, so as to stack the empty tray 3 on the full tray 3 loaded with the LED plates 7, thereby completing the automatic stacking of the trays 3 loaded with the LED plates 7; finally, after the plate collecting and stacking device 5 repeats the stacking of several trays 3 loaded with the LED plates 7, the unloading device 6 moves the stacked trays 3 out of the LED automatic plate collecting machine from the plate collecting and stacking device 5, thereby completing the automatic unloading of the stacked trays 3. As can be seen, the LED automatic plate collecting machine can automatically store the LED plate 7 into the tray 3 through the cooperation of the LED plate conveying device 2, the tray conveying device 4 and the plate collecting and stacking device 5, and after the storage, the plate collecting and stacking device 5 and the unloading device 6 can cooperate to automatically stack and unload the tray 3, instead of manual stacking and unloading, and the whole storage, stacking and unloading process is all performed automatically, which effectively improves the automation degree of the LED plate 7 production process, reduces the labor cost, thereby effectively improves the production efficiency of the LED plate 7 and ensures the product safety and personnel safety.

[0055] The LED automatic plate collecting machine loads the LED plate 7 and the empty tray 3 through the LED plate conveying device 2 and the tray conveying device 4 respectively, and the two feeding operation spaces do not overlap with each other, can be independently performed, do not interfere with each other, and effectively improve the plate collecting efficiency of the LED plate 7.

[0056] Referring to FIGS. 1 to 5, Figure 1 and Figure 2 , Figure 2As shown in the structural schematic diagram of the tray conveying device, the plate collecting and stacking device and the discharging device in the embodiment, in an embodiment of the plate collecting and stacking device 5, the plate collecting and stacking device 5 comprises a suction cup 51, a mechanical arm 52, a first carrier plate 53 and a first carrier plate driving mechanism 54. The suction cup 51 is used to adsorb or release the LED plate 7. The mechanical arm 52 is arranged on the rack 1 by screwing or welding and the like, and is in driving connection with the suction cup 51. The mechanical arm 52 is used to drive the suction cup 51 to reciprocate between the plate collecting station 13 and the first feeding station 11, and between the plate collecting station 13 and the second feeding station 12. The first carrier plate 53 is used to carry the tray 3, and the first carrier plate 53 is opposite to the plate collecting station 13. The first carrier plate driving mechanism 54 is arranged on the rack 1 by screwing or welding and the like, and is in driving connection with the first carrier plate 53. The first carrier plate driving mechanism 54 is used to drive the first carrier plate 53 to ascend or descend towards or away from the plate collecting station 13. In this way, when the plate is collected and stacked, first, the mechanical arm 52 drives the suction cup 51 to contact the empty tray 3 of the second feeding station 12, and the suction cup 51 adsorbs and grabs the empty tray 3. Then, the mechanical arm 52 drives the suction cup 51 and the empty tray 3 on the suction cup 51 to move to the plate collecting station 13, and then the suction cup 51 releases the empty tray 3, so as to place the empty tray 3 on the first carrier plate 53 of the plate collecting station 13. After that, the mechanical arm 52 drives the suction cup 51 to contact the LED plate 7 of the first feeding station 11, and the suction cup 51 adsorbs and grabs the LED plate 7. The mechanical arm 52 drives the suction cup 51 and the LED plate 7 on the suction cup 51 to move to a containing groove 31 of the tray 3 of the plate collecting station 13, and the suction cup 51 releases the LED plate 7 to place the LED plate 7 in the containing groove 31. After the tray 3 is fully loaded with the LED plate 7, the first carrier plate driving mechanism 54 drives the first carrier plate 53 to move downward by a height of the tray 3, so as to move the tray 3 fully loaded with the LED plate 7 out of the plate collecting station 13, so that the mechanical arm 52 and the suction cup 51 cooperate to transfer the next empty tray 3 to the plate collecting station 13, so as to be stacked on the tray 3 fully loaded with the LED plate 7. As can be seen, the plate collecting and stacking device 5 can grab both the tray 3 and the LED plate 7 through cooperation of the mechanical arm 52 and the suction cup 51, which greatly saves the equipment cost, and in combination with the first carrier plate 53 and the first carrier plate driving mechanism 54, the tray 3 can be automatically stacked, which is convenient for subsequent overall discharging and storage.

[0057] The suction cup 51 can use an existing vacuum suction cup 51 to grab the LED board 7 and the tray 3 by negative pressure adsorption. The suction cup 51 can also be replaced by a gripping mechanism such as a clamping cylinder, but compared with a rigid gripping method such as a clamping cylinder, the suction cup 51 flexibly grabs the LED board 7, which can better avoid damage such as bumps to the LED board 7. The manipulator 52 can use an existing manipulator 52, and its output end is connected to the suction cup 51 by screwing or welding. The first carrier drive mechanism 54 can use an existing linear displacement drive mechanism such as a ball screw linear module or a linear motor linear module, and its output end is connected to the first carrier 53 by screwing or welding.

[0058] See Figure 1 and Figure 2 As shown, based on the above embodiment, the plate collecting and stacking device 5 further includes a plate collecting position detection member 55 and a plate collecting and positioning mechanism 56. Both the plate collecting position detection member 55 and the plate collecting and positioning mechanism 56 are mounted on the frame 1 by screwing or welding, and are positioned opposite the plate collecting station 13. The plate collecting position detection member 55 is used to detect whether the material tray 3 has been transferred to the plate collecting station 13, and the plate collecting and positioning mechanism 56 is used to fix or release the material tray 3 in the plate collecting station 13. In this way, when the board collection detection part 55 detects that the material tray 3 is transferred to the board collection station 13, the board collection positioning mechanism 56 fixes the material tray 3 on the board collection station 13, and then the robot 52 and the suction cup 51 cooperate to place the LED board 7 in the receiving groove 31 of the material tray 3; after the material tray 3 is fully loaded with LED boards 7, the board collection positioning mechanism 56 releases the material tray 3, and the first carrier plate driving mechanism 54 drives the first carrier plate 53 to move down the height of a material tray 3, and moves the material tray 3 fully loaded with LED boards 7 out of the board collection station 13. It can be seen that during the board collecting process, the board collecting positioning mechanism 56 fixes the material tray 3 on the board collecting station 13, which can effectively prevent the material tray 3 from moving during the board collecting process, affecting the board collecting operation of the board collecting and stacking device 5, and thus affecting the accuracy of the board collecting operation; and after the material tray 3 is fully loaded with LED boards 7, the board collecting positioning mechanism 56 releases the material tray 3, which can facilitate the first carrier plate 53 and the first carrier plate driving mechanism 54 to drive the material tray 3 fully loaded with LED boards 7 to descend and move out of the board collecting station 13, leaving the board collecting station 13 empty, and then facilitate the next empty material tray 3 to be transferred to the board collecting station 13 and stacked on the material tray 3 fully loaded with LED boards 7.

[0059] The plate closing position detection member 55 can use a position sensor or an infrared sensor. The plate closing positioning mechanism 56 can use an existing telescopic mechanism such as a telescopic cylinder or a telescopic pole. In this way, when the output end of the plate closing positioning mechanism 56 is extended, it can be pressed against the material tray 3 to fix the material tray 3 on the plate closing station 13. Conversely, when the output end of the plate closing positioning mechanism 56 is retracted, the material tray 3 can be released.

[0060] See Figure 1 andFigure 2 As shown in FIG. 6, in one embodiment of the discharging device 6, the discharging device 6 comprises a discharging conveyor belt 61. The discharging conveyor belt 61 is installed on the frame 1, and is used to drive the tray 3 on the first carrier plate 53 to move away from the first carrier plate 53. In this way, the discharging device 6 can remove the tray 3 stacked on the first carrier plate 53 from the LED automatic tray collecting machine as a whole through the discharging conveyor belt 61, so as to realize automatic discharging of the stacked tray 3, and the discharging conveyor belt 61 can be connected with the storage conveying line, so as to also realize automatic storage of the stacked tray 3, effectively improve the automation degree of the LED plate 7 production process, reduce the labor cost, effectively improve the production efficiency of the LED plate 7, and ensure the product safety and personnel safety.

[0061] The above-mentioned discharging conveyor belt 61 can use an existing conveying belt, and can use a motor and gear combination driving mode for conveying. The above-mentioned discharging conveyor belt 61 can also use a conveying chain or a transplanting mechanism as a conveying mechanism.

[0062] Referring to FIGS. 7 and 8, Figure 1 and Figure 3 As shown, Figure 3 FIG. 7 is a perspective view of the LED plate conveying device in the embodiment, and FIG. 8 is a sectional view of the LED plate conveying device in the embodiment. In one embodiment of the LED plate conveying device 2, the LED plate conveying device 2 comprises a first lifting mechanism 21 and a first conveyor belt mechanism 22. The first lifting mechanism 21 is arranged on the frame 1 by screwing or welding. The first conveyor belt mechanism 22 is installed on the output end of the first lifting mechanism 21 and is opposite to the first feeding station 11. The first conveyor belt mechanism 22 is provided with at least two storage stations 221 for storing the LED plate 7, and is used to drive the LED plate 7 to be sequentially input to each storage station 221 towards the first feeding station 11. The first lifting mechanism 21 is used to drive the first conveyor belt mechanism 22 to move up or down towards or away from the first feeding station 11. In this way, when feeding the LED plate 7, at least two LED plates 7 can be input to the first conveyor belt mechanism 22 from outside the LED automatic tray collecting machine and sequentially stored in each storage station 221; then, the first lifting mechanism 21 drives the first conveyor belt mechanism 22 to move up towards the first feeding station 11, so as to move the LED plate 7 on the first conveyor belt mechanism 22 into the first feeding station 11, thereby realizing automatic feeding of the LED plate 7. It can be seen that the LED plate conveying device 2 can convey at least two LED plates 7 to the first feeding station 11 at one time, without repeatedly feeding the LED plate 7 multiple times, thereby greatly improving the tray collecting efficiency.

[0063] The above-mentioned first lifting mechanism 21 can use a linear displacement driving mechanism such as a ball screw linear module or a linear motor linear module.

[0064] The at least two storage stations 221 can be designed to be opposite to the first feeding station 11. In this way, after the first conveying belt mechanism 22 is raised towards the first feeding station 11, the LED panel 7 in each of the at least two storage stations 221 can be moved into the first feeding station 11, so that the mechanical hand 52 can grasp the LED panel 7 in any of the at least two storage stations 221; or among the at least two storage stations 221, the innermost storage station 221 can be designed to be opposite to the first feeding station 11. In this way, after the first conveying belt mechanism 22 is raised towards the first feeding station 11, the LED panel 7 in the innermost storage station 221 can be moved into the first feeding station 11, so that the mechanical hand 52 can only grasp the LED panel 7 in the innermost storage station 221. After the LED panel 7 in the innermost storage station 221 is grasped, the first conveying belt mechanism 22 can drive the LED panel 7 thereon to move one storage station 221 along the conveying direction, so as to move the next LED panel 7 into the first feeding station 11 for grasping by the mechanical hand 52. The above two embodiments can be selected according to customer requirements.

[0065] On the basis of the above embodiment, the tray 3 has at least two accommodating grooves 31, the number of the suction cups 51, the accommodating grooves 31 and the storage stations 221 is the same and one-to-one corresponding. In this way, the panel collecting and stacking device 5 can grasp and transfer at least two LED panels 7 at a time, further improving the panel collecting efficiency.

[0066] Referring to Figure 3 In one embodiment of the first conveying belt mechanism 22, the first conveying belt mechanism 22 includes two first conveying belts 222 which are parallel and symmetrically distributed, and one or both of the first conveying belts 222 is / are slidingly connected to the output end of the first lifting mechanism 21. The LED panel conveying device 2 further includes a spacing adjustment mechanism 23 which is drivingly connected to one or both of the first conveying belts 222, for driving the two first conveying belts 222 to move closer to or away from each other, so that the spacing of the two first conveying belts 222 is adapted to the LED panel 7 to be collected. In this way, the LED automatic panel collecting machine can feed LED panels 7 of different sizes through the LED panel conveying device 2, greatly improving the application range of the LED automatic panel collecting machine.

[0067] The above first conveying belt 222 can use an existing conveying belt, and can use a motor and gear combination to drive the conveying. The above first conveying belt 222 can also use a conveying chain or a transplanting mechanism instead.

[0068] The above-mentioned two first conveyor belts 222 can be arranged on the output end of the first lifting mechanism 21 by screwing or welding, and the other can be slidably connected to the output end of the first lifting mechanism 21 by a slide rail, and the spacing adjustment mechanism 23 can use an existing linear displacement drive mechanism such as a ball screw linear module or a linear motor linear module, and be fixed on the previous first conveyor belt 222 or on the output end of the first lifting mechanism 21 by screwing or welding, and the output end of the spacing adjustment mechanism 23 is fixed to the next first conveyor belt 222 by screwing or welding; or the above-mentioned two first conveyor belts 222 can both be slidably connected to the output end of the first lifting mechanism 21 by a slide rail, and the spacing adjustment mechanism 23 can use an existing bidirectional linear displacement drive mechanism such as a bidirectional screw linear module, and be fixed on the output end of the first lifting mechanism 21 by screwing or welding, and the output end of the spacing adjustment mechanism 23 is fixed to the two first conveyor belts 222 by screwing or welding. In the above two embodiments, the spacing adjustment mechanism 23 can adjust the spacing between the two first conveyor belts 222 .

[0069] See Figure 3 As shown, based on the above embodiment, the LED board conveying device 2 further includes a first in-place detection member 24 and a first positioning mechanism 25. Both the first in-place detection member 24 and the first positioning mechanism 25 are attached to the frame 1 by screwing or welding. The number of first in-place detection members 24, first positioning mechanisms 25, and storage stations 221 are the same and correspond to each other. The first in-place detection member 24 is used to detect whether an LED board 7 has been entered into a storage station 221, and the first positioning mechanism 25 is used to secure or release the LED board 7 in each storage station 221. In this way, when in use, the first conveyor belt 222 inputs each LED board 7 into each storage station 221 in sequence along the conveying direction. When the first in-position detection member 24 detects that the LED board 7 is input into the corresponding storage station 221, the corresponding first positioning mechanism 25 fixes the LED board 7 on the corresponding storage station 221 to prevent the LED board 7 from deviating from the corresponding storage station 221 before the board is collected, affecting the board collecting and stacking device 5 to grasp the LED board 7, and thus affecting the accuracy of the board collecting operation; until the board is collected or feeding is required, the first positioning mechanism 25 releases the corresponding LED board 7 so that the board collecting and stacking device 5 can grasp the LED board 7 for the board collecting operation, or so that the first conveyor belt 222 can input the LED board 7 into the next empty storage station 221.

[0070] The first in-position detection member 24 may be a position sensor or an infrared sensor. The first positioning mechanism 25 may be a telescopic mechanism such as an existing telescopic cylinder or a telescopic pole. In this way, when the output end of the first positioning mechanism 25 is extended, it can abut against the LED board 7 and fix the LED board 7 on the storage station 221. Conversely, when the output end of the first positioning mechanism 25 is retracted, the LED board 7 can be released.

[0071] See Figure 1 and Figure 2 As shown, in one embodiment of the tray conveyor device 4, the tray conveyor device 4 includes a second conveyor belt mechanism 41, a second carrier plate 42, and a second carrier plate driving mechanism 43. The second conveyor belt mechanism 41 and the second carrier plate driving mechanism 43 are both mounted on the frame 1 by screwing or welding. The second conveyor belt mechanism 41 is used to drive the stacked trays 3 toward the second carrier plate 42. The second carrier plate driving mechanism 43 is in transmission connection with the second carrier plate 42 and is used to drive the second carrier plate 42 to move upward or downward toward or away from the second loading station 12. In this way, when loading the material tray 3, first, the second conveyor belt mechanism 41 inputs one or a stack of material trays 3 onto the second carrier plate 42, and then the second carrier plate driving mechanism 43 drives the second carrier plate 42 to rise toward the second loading station 12, and the one or a stack of material trays 3 thereon can be lifted up and rise accordingly, leaving the second conveyor belt mechanism 41, and the material tray 3 or the uppermost material tray 3 of the stack of material trays 3 can be moved into the second loading station 12, so that the plate collecting and stacking device 5 can grab the material tray 3 of the second loading station 12 for the plate collecting operation; the second loading station After the material tray 3 of the station 12 is grabbed, if there is still a material tray 3 on the second carrier 42, the second carrier driving mechanism 43 drives the second carrier 42 to rise toward the second loading station 12 by the height of a material tray 3, so as to move the next material tray 3 on the second carrier 42 into the second loading station 12. If there is no material tray 3 on the second carrier 42, the second carrier driving mechanism 43 drives the second carrier 42 to descend back to its original position with its back to the second loading station 12, and the second conveyor belt mechanism 41 inputs the next or next stack of material trays 3 onto the second carrier 42. It can be seen that the second conveyor belt mechanism 41 and the second carrier 42 can both carry multiple stacked material trays 3. The material tray conveying device 4 includes the second conveyor belt mechanism 41, the second carrier 42 and the second carrier driving mechanism 43, which can not only automatically convey the loaded material tray 3, but also convey and load multiple stacked material trays 3 at one time. In this way, there is no need to repeatedly load the material tray 3, which can further improve the plate collection efficiency.

[0072] The second conveyor belt mechanism 41 can utilize any existing conveying mechanism, such as a motor-conveyor belt mechanism, a motor-conveyor chain mechanism, or a transfer mechanism. The second carrier plate drive mechanism 43 can utilize an existing linear displacement drive mechanism, such as a ball screw linear module or a linear motor linear module, with its output end connected to the second carrier plate 42 by screwing or welding.

[0073] See Figure 1 and Figure 2 As shown, based on the above embodiment, the tray conveying device 4 further includes a second in-place detection member 44 and a second positioning mechanism 45. The second in-place detection member 44 and the second positioning mechanism 45 are both mounted on the frame 1 by screwing or welding, and are positioned opposite the second loading station 12. The second in-place detection member 44 is used to detect whether the tray 3 has been conveyed to the second loading station 12, and the second positioning mechanism 45 is used to secure or release the tray 3 at the second loading station 12. In this way, when in use, the second conveyor belt mechanism 41, the second carrier plate 42 and the second carrier plate driving mechanism 43 cooperate to input the material tray 3 into the second loading station 12. When the second in-place detection member 44 detects that the material tray 3 is input into the second loading station 12, the second positioning mechanism 45 fixes the material tray 3 on the second loading station 12 to prevent the material tray 3 from moving and deviating from the second loading station 12, affecting the plate collecting and stacking device 5 to grasp the material tray 3, and thus affecting the accuracy of the plate collecting operation; until the plate is collected, the second positioning mechanism 45 releases the material tray 3 so that the plate collecting and stacking device 5 can grasp the material tray 3 for the plate collecting operation.

[0074] The second in-position detection member 44 may be a position sensor or an infrared sensor. The second positioning mechanism 45 may be a telescopic mechanism such as an existing telescopic cylinder or a telescopic pole. In this way, when the output end of the second positioning mechanism 45 is extended, it can be pressed against the material tray 3 to fix the material tray 3 on the second loading station 12. Conversely, when the output end of the second positioning mechanism 45 is retracted, the material tray 3 can be released.
