Description

Technical Field

[0001] The present invention belongs to the field of conveying technology, and specifically relates to a conveying device for fragile thin plates, and more particularly to a conveying device for LED backplane detection and a working method thereof. Background Art

[0002] After LED production is completed, the brightness of the lamp beads needs to be tested. In related technologies, this is usually achieved by combining conveying equipment with image acquisition equipment. The conveying equipment transports the LED to be tested to the bottom of the image acquisition camera, and then transports the LED away after the image acquisition is completed.

[0003] Since LED backplanes come in various sizes, a conveying device with adjustable width is used in related art to convey them. The distance between the two conveyor belts in the conveying device is adjusted to match LED backplanes of different specifications.

[0004] A significant problem with width-adjustable conveying devices is that the side panels of the conveyor belt will shift on the drive shaft, causing the lubricating oil on the transmission gear to be smeared on the drive shaft. When the drive shaft rotates, the lubricating oil will be thrown onto the back of the LED backplane. Due to the complex circuitry of the LED backplane, subsequent cleaning becomes more difficult.

[0005] Therefore, it is urgently necessary to provide a conveying device for LED backplane inspection and a working method thereof to solve the technical problem in the related art that lubricating oil is easily thrown to the back of the LED backplane.

[0006] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0026] In an optional embodiment, a cleaning sponge is further attached to the bottom of the cleaning plate, and the cleaning sponge is configured to absorb lubricating oil on the output shaft; and

[0027] When the cleaning plate moves, the position of the cleaning sponge corresponds to the position of the squeezing push block, and the squeezing push block extends to squeeze the cleaning sponge to squeeze out the lubricating oil absorbed by the cleaning sponge.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0050] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.

[0051] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0052] See also Figure 1 , Figure 1 A conveying device for LED backplane inspection is shown, comprising: a supporting base plate 1, one side of which is fixedly provided with a first conveying side plate 11, and the other side of which is slidably provided with a second conveying side plate 12; a transmission motor 13, the output shaft 14 of the transmission motor 13 respectively passes through the first conveying side plate 11 and the second conveying side plate 12 to simultaneously drive the transmission gears 15 on the two side plates to rotate; and a shielding wheel 2, which is provided on the transmission gear 15 of the second conveying side plate 12; and the shielding wheel 2 is configured to clean the output shaft 14 of the transmission motor 13 when the second conveying side plate 12 moves.

[0053] In this embodiment, the conveying side plates are configured as one fixed and the other movable, and the distance between the two conveying side plates can be adjusted by moving the movable second conveying side plate 12. The transmission motor 13 is coordinated with the output shaft 14, so that the transmission motor 13 can simultaneously drive the transmission belts on the first conveying side plate 11 and the second conveying side plate 12 to rotate synchronously at the same speed. At the same time, the shielding wheel 2 provided on the transmission gear 15 of the second conveying side plate 12 can block the lubricating oil on the output shaft 14 when the transmission motor 13 rotates, so as to prevent the output shaft 14 from throwing the lubricating oil to the back of the LED back panel when rotating, causing product contamination.

[0054] Specifically, in order to achieve adjustable width, the conveying side plate needs to be configured to be movable. Therefore, one of the conveying side plates needs to slide along the output shaft 14 of the transmission motor 13. In order to ensure smooth sliding and smooth rotation of the output shaft 14, it is necessary to apply lubricating oil or grease between the output shaft 14 of the motor and the conveying side plate. For LED backplane testing, although grease is used, the grease will be unevenly liquefied due to the long-term light emission and heat generation during the lighting test of the LED backplane, which will cause the lubricating oil or liquefied grease to be thrown to the back of the LED backplane when the output shaft 14 rotates. Since the LED backplane is usually provided with electronic components such as terminal blocks and circuits, if the lubricating oil or grease is stuck at this time, a complicated cleaning process will be required later.

[0055] See also Figure 2 and Figure 3In some embodiments, a shielding wheel 2 is provided on the transmission gear 15 of the second conveying side plate 12, and the shielding wheel 2 is located on the outside of the transmission gear 15, that is, the shielding wheel 2 is located on the side of the transmission gear 15 close to the first conveying side plate 11. When the second conveying side plate 12 moves toward the first conveying side plate 11, the shielding wheel 2 contacts the output shaft 14 before the transmission gear 15. At this time, the cleaning plate 22 of the shielding wheel 2 first smears the output shaft 14, so that the transmission gear 15 can slide smoothly. When the second conveying side plate 12 moves in a direction away from the first conveying side plate 11, the shielding wheel 2 contacts the output shaft 14 after the transmission gear 15, thereby wiping off the lubricating oil remaining after the transmission gear 15 moves, so that there is no lubricating oil residue on the exposed surface of the output shaft 14, thereby avoiding subsequent pollution problems.

[0056] See also Figure 4 In some embodiments, a plurality of cleaning grooves 23 are provided in the wheel body 21 of the shielding wheel 2. The positions of the cleaning grooves 23 correspond to the positions of the side walls of the output shaft 14. In addition, a spring 24 connected to the cleaning plate 22 is provided in the cleaning groove 23. Preferably, the spring 24 is configured as a tension spring 24, that is, the spring 24 applies a thrust to the cleaning plate 22, so that the cleaning plate 22 can be attached to the side wall of the output shaft 14. When the conveying equipment performs normal conveying work, the shielding wheel 2 will rotate with the transmission gear 15. At this time, the cleaning plate 22 will be subjected to the centrifugal force to move toward the cleaning groove 23. The bottom of the groove moves, so that the cleaning plate 22 is separated from the side wall of the output shaft 14. At this time, the distance between the cleaning plate 22 and the side wall of the output shaft 14 is used for the lubricating oil to be thrown out. That is, the cleaning plate 22 is configured to not contact the output shaft 14 at this time, so as to provide space for the lubricating oil to be thrown out. Specifically, when the lubricating oil generates centrifugal force due to the rotation of the output shaft 14, the lubricating oil will have a tendency to move. If the cleaning plate 22 is always in contact with the output shaft 14, the lubricating oil may move toward the outside of the shielding wheel 2 due to the squeezing of the cleaning plate 22, which will cause the lubricating oil to flow out of the shielding wheel 2 and cause pollution.

[0057] In some embodiments, an extrusion push block 26 is further provided in the shielding wheel 2; the extrusion push block 26 is configured to extend from the shielding wheel 2 after the cleaning plate 22 moves, so as to push the lubricating oil on the cleaning plate 22 back to the transmission gear 15, that is, the extrusion push block 26 is configured to be forced to move toward the inner side of the shielding wheel 2 after the shielding wheel 2 rotates, and the distance of its movement includes but is not limited to 3 / 4 of the width of the cleaning plate 22. At this time, the extrusion push block 26 will squeeze the cleaning sponge at the bottom of the cleaning plate 22, so that the lubricating oil absorbed in the cleaning sponge is squeezed out, and the squeezed lubricating oil will be pushed to the transmission gear 15 under the action of the extrusion push block 26, so that the lubricating oil can lubricate the transmission gear 15 again.

[0058] Specifically, the extrusion push block 26 is arranged in the accommodating groove, and the accommodating groove is located at the groove mouth of the cleaning groove 23; an elastic member 27 is provided at the bottom of the accommodating groove, and the elastic member 27 is configured to be used to pull the extrusion push block 26 back into the accommodating groove, and a connecting air channel 25 is opened between the cleaning groove 23 and the accommodating groove; the air inlet of the connecting air channel 25 is located at the bottom of the cleaning groove 23, and the air outlet of the connecting air channel 25 is located at the bottom of the accommodating groove; when the cleaning plate 22 moves toward the bottom of the cleaning groove 23, it pushes the gas in the cleaning groove 23 to flow from the air inlet through the air outlet to the accommodating groove, thereby pushing the extrusion push block 26 out.

[0059] As an optional embodiment, the cleaning plate 22 cooperates with the cleaning sponge and the extrusion push block 26 so that the lubricating oil can be absorbed and reused repeatedly, thereby avoiding the contamination of the back of the LED caused by the lubricating oil remaining on the output shaft 14 when the conveying side plate moves, and avoiding the rotation jamming problem caused by insufficient lubricating oil due to the use of a single lubricating oil absorption in the related art.

[0060] In some embodiments, the cross section of the output shaft 14 is a regular hexagon; and a connecting hole that matches the shape of the output shaft 14 is defined in the output shaft 14 and the transmission gear 15 .

[0061] In some embodiments, the conveying equipment also includes: a pushing screw 17, which is connected to the second conveying side plate 12; wherein the pushing screw 17 is configured to push the second conveying side plate 12 to move to adjust the distance between the first conveying side plate 11 and the second conveying side plate 12.

[0062] In some embodiments, the conveying device further includes: a conveying belt 16 , which is connected to the transmission gear 15 ; and the conveying belt 16 is configured to convey the LED back panel to be tested to move under the drive of the transmission gear 15 .

[0063] On the second aspect, some embodiments also provide a working method of a conveying device for LED backplane detection, including: using the above-mentioned conveying device for LED backplane detection; and adjusting the distance between the first conveying side plate 11 and the second conveying side plate 12 by pushing the screw rod 17; when the second conveying side plate 12 moves, the cleaning plate 22 is displaced in accordance with the output shaft 14 to absorb the lubricating oil remaining on the surface of the output shaft 14; when the transmission gear 15 rotates, the cleaning plate 22 is rotated by centrifugal force to drive the extrusion push block 26 to extend and push the adsorbed lubricating oil to the transmission gear 15.

[0064] In summary, the conveying equipment for LED backplane inspection adjusts the width of the conveying equipment by adjusting the distance between the first conveying side plate 11 and the second conveying side plate 12, thereby adapting to LED backplanes of different width specifications. At the same time, the shielding wheel is used to wipe the output shaft 14 of the transmission motor 13 when the second conveying side plate 12 moves. Specifically, the cleaning plate 22 of the shielding wheel is attached to the outer wall of the output shaft 14, thereby wiping the output shaft 14 when the shielding wheel moves. The squeezing push block 26 provided in the shielding wheel can extend when the shielding wheel rotates with the transmission gear 15 to squeeze the cleaning sponge provided on the bottom of the cleaning plate 22, and push the lubricating oil absorbed by the cleaning plate 22 when it moves back to the transmission gear 15 to ensure that the transmission gear 15 rotates and moves smoothly in the future.
