Description

Technical Field

[0001] The present invention belongs to the technical field of license plate production, and specifically relates to an electric writing device for electric vehicle license plates. Background Art

[0002] RFID electronic license plates are an intelligent license plate system based on radio frequency identification technology. By installing electronic tags containing unique identification codes on vehicles, they can achieve precise identification and full-process traceability of vehicle identities, and have advantages such as non-contact identification, high accuracy, comprehensive information recording, and support for intelligent supervision.

[0003] With the continuous progress of urban construction, RFID electronic license plates will play a more important role in urban traffic management. In order to meet the unified management of a large number of electric vehicles and equip electric vehicle license plates as soon as possible, the production of electric vehicle license plates also needs to improve efficiency accordingly. The electric vehicle license plates contain readable electronic tags. Before leaving the factory, the corresponding personnel and vehicle information needs to be written in. Currently, the manual transfer method is still used, and the electric vehicle license plates are placed one by one for electric writing, which reduces the production efficiency and increases the production cost.

[0004] A Chinese patent with the authorization announcement number CN215833931 U discloses an electric writing device for electric vehicle license plates, including a machine body, an industrial control computer with an information processing device that is controlled and connected to the machine body. A storage bin is arranged on the machine body, and multiple electric vehicle license plates with electronic tags are stacked in the storage bin. It also includes a transfer platform arranged on the machine body. A pusher mechanism capable of pushing out multiple electric vehicle license plates one by one is arranged along one side of the storage bin on the transfer platform. An electric writing device controlled and connected to the industrial control computer is arranged along the other side of the storage bin on the transfer platform. The electric vehicle license plates stored in batches in the storage bin are pushed out through the pusher mechanism, the electronic tag information of the electronic license plates is identified by a scanning gun, and the electric writing device using an RFID tag reader / writer reads and writes the electronic tag information. When the electric writing of a batch of electric vehicle license plates is completed, these electric vehicle license plates are put back into the storage bin, and the written electric vehicle license plates stored in this batch in the storage bin are pushed out through the pusher mechanism. The electric writing device using an RFID tag reader / writer reads the electronic tag information of the electric vehicle license plates, and after reading, it is fed back to the industrial control computer with a data processing device, and the electronic tag information is verified through data processing to improve the production efficiency of electric vehicle license plates.

[0005] However, the above patent still has the following disadvantages:

[0006] 1. The above patent requires the license plates to be put into the storage bin in batches. After identifying and electrically writing the license plates in sequence, the operator still needs to put the written license plates back into the storage bin and run the above patent again for verification operations. This process has meaningless repetitive work, and the electric writing process and the verification process are not continuous, so efficient and continuous production and processing cannot be achieved, affecting the production efficiency of license plates.

[0007] 2. During the actual electro-writing and verification processes, due to processing defects in some license plates themselves, the RFID chips inside the license plates cannot work properly, or electro-writing errors occur due to being affected during the writing process, resulting in the final RFID information being unreadable or the read information being incorrect. In such cases, the above patent requires manual removal of the license plates with verification errors after stopping the machine, which wastes time and affects the production efficiency of license plates. Summary of the Invention

[0008] In order to overcome the deficiencies of the prior art, the technical problem solved by the present invention is that by setting a feeding bin, the license plates to be electro-written are stacked and placed in the feeding bin, which facilitates the subsequent pushing component to push the license plates one by one to the electro-writer for electro-writing, and the information on the license plates to be electro-written is identified and recorded one by one through the first scanner, realizing automatic and efficient RFID electro-writing processing of license plates. By setting a second scanner and a reader, it can be checked whether the electro-writing information of the license plates entering the switching platform is accurate or whether electro-writing fails. When there are incorrect license plates, the positions of the two switching platforms can be swapped, so that the empty switching platform continues at the end of the slide rail. Without affecting the subsequent continuous electro-writing processing, the incorrect license plates are quickly ejected from the electro-writing processing area through the top plate, realizing automatic and efficient exclusion of incorrect license plates and improving the electro-writing processing efficiency. Through the settings of the third buckle plate, the first buckle plate, and the second buckle plate, the license plates entering the electro-writing area and the verification area can be restricted, avoiding the problem that multiple license plates are stacked and pressed in the electro-writing or verification area, affecting normal electro-writing and verification. Moreover, the first buckle plate can play a role in restricting the flipping direction of the license plate when the top plate ejects the license plate, avoiding the license plate falling on the electro-writing production line again and affecting normal work.

[0018] By setting up an electric drive cylinder and cooperating with the first clip plate, the wrong license plate can be thrown to the outside of the electronic writing equipment, so as to achieve efficient and rapid elimination of the wrong license plate and prevent the wrong license plate from falling into the electronic writing production line and affecting the subsequent normal electronic writing work.

[0019] Two guide plates are fixedly connected between the two side plates and located below the two switching platforms. Two guide grooves of different heights are provided in each guide plate. Both ends of each guide groove have upwardly inclined parts. A group of sliding pins are fixedly connected at the corresponding positions of the guide plates at the bottom of each switching platform. Each group of sliding pins is slidably connected to the two guide grooves of different heights.

[0026] (2) By providing a second scanner and a reader, it is possible to check whether the electric writing information of the license plates entering the switching platform is accurate or whether the electric writing fails. When there is an incorrect license plate, the positions of the two switching platforms can be swapped, so that the empty switching platform continues at the end of the slide rail. Without affecting the subsequent continuous electric writing processing, the incorrect license plate is quickly ejected from the electric writing processing area by the top plate, realizing the automatic and efficient exclusion of incorrect license plates and improving the electric writing processing efficiency.

Detailed implementation manners

[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] As Figure 1 and Figure 2 shown, an electric writing device for an electric vehicle license plate includes a bottom plate 49. Two symmetrically arranged side plates 24 are fixedly connected to the top of the bottom plate 49. A first slide rail frame 20 is fixedly connected between the two side plates 24. A second slide rail frame 22 is fixedly connected to the bottom plate 49. A slide rail 10 is fixedly connected to the second slide rail frame 22 and the first slide rail frame 20. A feeding bin 12 is fixedly connected to the slide rail 10. A license plate 11 is placed in the feeding bin 12. An electric writing device 13 is embedded in one end of the slide rail 10 away from the feeding bin 12. An electric writing support plate 19 fixed between the two side plates 24 is fixedly connected to the bottom side of the electric writing device 13. A bracket 14 is fixedly connected to the electric writing support plate 19 and the first slide rail frame 20. A first support 15 is fixedly connected to the bracket 14 above the slide rail 10. A first scanner 16 facing the slide rail 10 is fixedly connected to the first support 15.

[0038] By setting up the feeding bin 12, the license plates 11 to be electrically written are stacked in the feeding bin 12, which facilitates the subsequent pusher components to push the license plates 11 one by one to the electric writer 13 for electrical writing. The information on the license plates 11 being electrically written is identified and recorded one by one through the first scanner 16, realizing the RFID electrical writing process of the license plates 11.

[0039] As Figure 1 , Figure 2 , Figure 6 and Figure 7 shown, on both sides of one end of the slide rail 10 away from the switching platform 26, two limiting bars 47 are fixedly connected. A push plate 44 is slidably connected between the two limiting bars 47. A shaft seat 43 is fixedly connected to the bottom side of the push plate 44. An avoidance groove 48 is provided on the slide rail 10 at the position where the shaft seat 43 moves. A motor seat 23 is fixedly connected to the slide rail 10 at the corresponding position of the push plate 44. A second motor 40 is fixedly connected to the motor seat 23. The power output end of the second motor 40 passes through the second motor 40 and is drivingly connected to a rocker arm 41. One end of the rocker arm 41 away from the second motor 40 is hinged to a connecting rod 42. One end of the connecting rod 42 away from the rocker arm 41 is hinged to the shaft seat 43.

[0040] By setting up the push plate 44 and using the rotation of the second motor 40 to reciprocate the push plate 44, the license plates 11 are pushed one by one to the electric writer 13 for electrical writing, and the subsequent license plates 11 are pushed again to continue pushing the license plates 11 after the electrical writing is completed, thus realizing the automatic electrical writing work.

[0041] As Figure 6 shown, on the slide rail 10, two baffles 46 are symmetrically and fixedly connected on both sides of the feeding bin 12. Each baffle 46 can be closely attached to the side of the license plate 11. Two symmetrically arranged third fasteners 45 are fixedly connected to the slide rail 10 on both sides of the electric writer 13. The two third fasteners 45 can cover the two side edges of the license plate 11 and slide relative to the license plate 11.

[0042] By setting up the baffles 46, when the push plate 44 pushes the license plate 11 to move, the license plate 11 can be limited and guided to ensure the stable sliding of the license plate 11 on the surface of the slide rail 10. By setting up the third fasteners 45, only one license plate 11 enters the third fasteners 45 each time, avoiding the problem of the license plates 11 being stacked on each other when the push plate 44 pushes the license plates 11, resulting in incorrect electrical writing or inability to perform electrical writing.

[0043] As Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, at one end of the sliding rail 10 away from the push plate 44, there are two closely fitted switching platforms 26. The two switching platforms 26 are at different heights and can slide horizontally. Each switching platform 26 can be fitted and continued with the end of the sliding rail 10. On the two sides of the two switching platforms 26 away from each other, there are respectively fixedly connected with first buckle plates 28. In the two sides of the two switching platforms 26 close to each other, there are respectively provided with chutes 30. In each chute 30, there is a second buckle plate 29 slidably connected. Between each second buckle plate 29 and the bottom of the corresponding chute 30, there is a set of springs 31. Between the two side plates 24 and below the switching platform 26, there is a fixedly connected reading support plate 21. On the reading support plate 21, there is a fixedly connected reader 25. One end of the bracket 14 close to the switching platform 26 is fixedly connected with a second support 17. The second support 17 is fixedly connected with a second scanner 18 facing the switching platform 26.

[0044] By setting the second scanner 18 and the reader 25, it is possible to check whether the electrical writing information of the license plate 11 entering the switching platform 26 is accurate or whether the electrical writing fails. When there is an incorrect license plate 11, by swapping the positions of the two switching platforms 26, the empty switching platform 26 can be continued with the end of the sliding rail 10. Without affecting the subsequent continuous electrical writing process, the incorrect license plate 11 can be quickly ejected from the electrical writing area through the top plate 27, realizing automatic and efficient exclusion of incorrect license plates and improving the electrical writing efficiency.

[0045] As Figure 4 and Figure 5 As shown, between each first buckle plate 28 and the switching platform 26, there is an inclined angle. The end of each second buckle plate 29 has an inclined surface. The bottom of each second buckle plate 29 can abut against the edge of another switching platform 26. On the surface of each switching platform 26, there is an embedded top plate 27. At the corresponding position of the bottom side of each switching platform 26, there is a set of electric cylinders 32 fixedly connected. The extending end of each set of electric cylinders 32 passes through the switching platform 26 and is fixedly connected with the top plate 27.

[0046] By setting the first buckle plate 28 and the second buckle plate 29, when the license plate 11 enters the switching platform 26, it also has the effect of preventing multiple license plates 11 from overlapping and affecting the recognition process. And by changing the relative height while the two switching platforms 26 switch positions, the expansion and contraction of the second buckle plate 29 can be controlled, so that the second buckle plate 29 no longer restricts the license plate 11 during the process of the top plate 27 ejecting the incorrect license plate 11.

[0047] And the first buckle plate 28 and the surface of the switching platform 26 are at an angle, and the first buckle plate 28 hooks on the outer edge of the license plate 11. Then during the process of the top plate 27 pushing the license plate 11, the license plate 11 automatically flips towards the outside of the device, thus preventing the license plate 11 from falling on the electrical writing production line again and affecting the normal electrical writing work.

[0048] As Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, a set of slide rods 33 are fixedly connected to the bottom side of each switching platform 26 between the electric drive cylinders 32. A slider 34 is slidably connected to each set of slide rods 33. A lead screw 35 threadedly connected to the two sliders 34 is rotatably connected between the two side plates 24. A first motor 36 is fixedly connected to the outer side of the side plate 24 at the corresponding position of the lead screw 35. The power output end of the first motor 36 is drivingly connected to the lead screw 35. Two guide plates 38 are fixedly connected between the two side plates 24 below the switching platform 26. Two staggered guide grooves 39 are formed in each guide plate 38. Both ends of each guide groove 39 have upwardly inclined portions. A slide pin 37 is fixedly connected to the bottom of each switching platform 26 near the guide plate 38. The end of each slide pin 37 is slidably connected to the corresponding guide groove 39.

[0049] By setting the threaded connection between the lead screw 35 and the slider 34, the slider 34 is driven to move the switching platform 26 horizontally, achieving the effect of switching the position of the switching platform 26 to exclude the wrong license plate 11. During the horizontal movement of the switching platform 26, it is guided by the guide groove 39, so that the height difference between the two switching platforms 26 changes, changing the telescopic states of the two second buckles 29.

[0050] In this embodiment, initially, the operator connects the device to the power supply and the control system. The operator puts the neatly stacked license plates 11 into the feeding bin 12. Subsequently, the second motor 40 is started through the control system to drive the rocker arm 41 to rotate. Then, due to the hinged connection between the rocker arm 41 and the connecting rod 42, the push plate 44 reciprocates. The limiting strip 47 can limit the movement of the push plate 44, ensuring that the push plate 44 always reciprocates in a straight line.

[0051] During the reciprocating movement of the push plate 44, the license plates 11 in the feeding bin 12 are pushed into the space between the two third buckles 45 one by one. Only one license plate 11 can enter between the two third buckles 45, effectively avoiding the stacking of multiple license plates 11 above the electric writer 13 and affecting the electric writing work. After the license plate 11 enters between the two third buckles 45, the electric writer 13 is aligned with the license plate 11, and the first scanner 16 identifies the label information of the license plate 11 and uploads it to the control system. The control system retrieves the corresponding information of the license plate and performs electric writing through the electric writer 13.

[0052] Subsequently, the push plate 44 reciprocates another stroke, pushing the subsequent license plate 11 further into the space between two third fasteners 45 to continue the electrical writing operation. The license plate 11 that has completed the electrical writing is pushed into the switching platform 26 by the subsequent license plate 11. At this time, one of the switching platforms 26 is in contact with and continues at the end of the slide rail 10, and the other switching platform 26 is located on one side and is higher in height than the switching platform 26 that continues with the slide rail 10. Then, the second fastener 29 in the switching platform 26 that continues with the slide rail 10 is blocked and retracted into the chute 30, while the second fastener 29 in the switching platform 26 that does not continue with the slide rail 10 is not blocked and extends out of the chute 30 under the thrust of the spring 31. The extended second fastener 29 and the first fastener 28 opposite to it work together to also achieve the effect of only allowing one license plate 11 to enter the switching platform 26, avoiding the stacking of license plates 11 and affecting the recognition effect.

[0053] After the license plate 11 that has completed the electrical writing enters the switching platform 26, the second scanner 18 recognizes the tag information of this license plate 11 and uploads it to the control system. At the same time, the reader 25 reads the electrical writing information of this license plate 11 and uploads it to the control system. The control system conducts a comparison and verification. If the verification is correct, the switching platform 26 does not change its position. When the push plate 44 pushes the subsequent license plate 11 into the switching platform 26, the verified license plate 11 is pushed off the switching platform 26. The operator can set a collection device at the end of the switching platform 26 to facilitate the collection of the license plate 11.

[0054] If the verified information is incorrect or the electrical writing information cannot be read, the control system starts the first motor 36 to drive the lead screw 35 to rotate, causing the slider 34 to drive the two switching platforms 26 to quickly switch positions. Then, the switching platform 26 with the incorrect license plate 11 is disengaged from the continuation with the slide rail 10, removing the incorrect license plate 11 from the electrical writing production line, and the empty switching platform 26 continues with the slide rail 10, waiting for the subsequent license plate 11 to enter the switching platform 26 for verification. Compared with the existing method, there is no need to put the license plate 11 back into the production line for verification, realizing automatic, continuous, and efficient electrical writing production and verification work, and improving production efficiency.

[0055] During the process of the two switching platforms 26 switching positions, the two switching platforms 26 will move along the trajectory of the guiding groove 39. During this process, the switching platform 26 that does not carry the incorrect license plate 11 will descend along the inclined part of the guiding groove 39, thus reducing its height. The inclined surface of the originally extended second fastener 29 slides by being squeezed by the switching platform 26, causing the originally extended second fastener 29 to retract into the chute 30. The switching platform 26 that carries the incorrect license plate 11 will be lifted upward along the trajectory of the guiding groove 39 at the end of the lateral movement stroke. Then, the second fastener 29 in this switching platform 26 is no longer blocked and extends out under the thrust of the spring 31, working together with the first fastener 28 to restrict the license plate 11.

[0056] At this time, only the first buckle plate 28 on the switching platform 26 carrying the wrong license plate 11 is in contact with the edge of the license plate 11, and the control system starts the corresponding electric drive cylinder 32 to lift the top plate 27 to lift the wrong license plate 11. During this process, the first buckle plate 28 holds the outer edge of the license plate 11 so that the license plate 11 can only flip to the outside of the equipment and finally detach from the switching platform 26. Finally, the electric drive cylinder 32 retracts to make the top plate 27 embed into the switching platform 26 again. While eliminating the wrong license plate 11, it prevents the wrong license plate 11 from falling on the electric writing production line again and affecting normal work. Due to the inclined angle design of the first buckle plate 28, the first buckle plate 28 will not completely lock the license plate 11 when the license plate 11 is flipped, ensuring that the license plate 11 can be smoothly flipped outward and detached from the switching platform 26.

[0057] The above-mentioned electric writer 13, first scanner 16, second scanner 18, reader 25, electric cylinder 32, first motor 36, second motor 40, etc. are mature existing technologies and will not be described in detail herein.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
