Description

Technical Field

[0001] The invention belongs to the technical field of license plate production, in particular to an electric writing device for electric license plates. Background Art

[0002] RFID electronic license plate is an intelligent license plate system based on radio frequency identification technology. It achieves accurate identification and full traceability of vehicle identity by installing electronic tags containing unique identification codes on vehicles. It has the advantages of 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, electric license plates should be equipped as soon as possible, and the production efficiency of electric license plates should be improved accordingly. Electric license plates contain readable electronic tags, and the corresponding personnel and vehicle information needs to be written before leaving the factory. At present, manual transmission is still used to place electric license plates one by one for electronic writing, which reduces production efficiency and increases production costs.

[0004] The authorization announcement number is CN215833931 U's Chinese patent discloses an electric writing device for electric vehicle license plates, including a machine body, an industrial computer with an information processing device connected to the machine body for control, a storage bin provided on the machine body, a plurality of electric vehicle license plates with electronic tags stacked in the storage bin, and a conveying platform provided on the machine body, a pushing mechanism capable of pushing out a plurality of electric vehicle license plates one by one is provided along one side of the storage bin on the conveying platform, an electronic writing device connected to the control of the industrial computer is provided along the other side of the storage bin on the conveying platform, the electric vehicle license plates stored in batches in the storage bin are pushed out by the pushing mechanism, the electronic tag information of the electronic license plates is identified by a scanning gun, the electronic tag information is read and written by the electronic writing device using an RFID tag reader / writer, after a batch of electric vehicle license plates are electronically written, the electric vehicle license plates are put back into the storage bin, the batch of electric vehicle license plates with written information stored in the storage bin are pushed out by the pushing mechanism, the electronic tag information of the electric vehicle license plates is read by the electronic writing device using an RFID tag reader / writer, and after reading, the electronic tag information is fed back to the industrial computer with a data processing device, and the electronic tag information is verified by 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 that the license plates be put into a storage bin in batches, and after the license plates are identified and electronically written in turn, the operator is required to put the written license plates back into the storage bin and run the above patent again for verification. This process involves meaningless repetitive work, and the electronic writing process and the verification process are not continuous, and efficient and continuous production and processing cannot be achieved, which affects the production efficiency of the license plates.

[0007] 2. In the actual electronic writing and verification process, due to processing defects in some license plates themselves, the RFID chip inside the license plate cannot work properly, or the electronic writing error occurs due to the influence during the writing process, resulting in the final RFID information being unable to be read or the read information being erroneous. When encountering this situation, the above patent requires manual shutdown and removal of the wrongly verified license plate, which wastes time and affects the production efficiency of the license plate.

By providing a second scanner and reader, it is possible to check whether the electronic writing information of the license plates entering the switching platform is accurate or whether the electronic writing fails. When an erroneous license plate appears, the positions of the two switching platforms can be swapped to make the empty license plates The switching platform connects to the end of the slide rail without affecting the subsequent continuous electro-writing processing. At the same time, the erroneous license plate can be quickly ejected from the electro-writing processing area through the top plate, thereby automatically and efficiently eliminating the erroneous license plate and improving the electro-writing processing efficiency. Through the setting 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 to avoid the problem of multiple license plates overlapping in the electro-writing or verification area, affecting the normal electro-writing and verification.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the solutions 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] like Figure 1 and Figure 2 As shown, an electric writing device for electric license plates includes a base plate 49, two symmetrical side plates 24 are fixedly connected to the top of the base 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 base plate 49, a slide rail 10 is fixedly connected to the second slide rail frame 22 and the first slide rail frame 20, a feed bin 12 is fixedly connected to the slide rail 10, a license plate 11 is placed in the feed bin 12, an electric writer 13 is embedded in the end of the slide rail 10 away from the feed 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 writer 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, and a first scanner 16 facing the slide rail 10 is fixedly connected to the first support 15.

[0038] By setting up a feed bin 12, the license plates 11 to be electronically written are stacked and placed in the feed bin 12, which makes it convenient for the subsequent pushing components to push the license plates 11 one by one to the electronic writer 13 for electronic writing, and the information on the license plates 11 to be electronically written is identified and recorded one by one through the first scanner 16, thereby realizing the RFID electronic writing processing of the license plates 11.

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

[0040] By setting a push plate 44 and utilizing the rotation of the second motor 40 to make the push plate 44 reciprocate, the license plates 11 are pushed one by one to the electronic writer 13 for electronic writing, and the subsequent license plates 11 are pushed again to continue pushing the license plates 11 after electronic writing, thereby realizing automatic electronic writing.

[0041] like Figure 6 As shown, two baffles 46 are symmetrically distributed and fixedly connected on both sides of the feed bin 12 on the slide rail 10, and each baffle 46 can fit tightly against the side of the license plate 11. Two third buckle plates 45 are symmetrically fixedly connected on both sides of the electric writer 13 on the slide rail 10, and the two third buckle plates 45 can cover the edges of both sides of the license plate 11 and slide relative to the license plate 11.

[0042] By setting the baffle 46, the license plate 11 can be limited and guided when the push plate 44 pushes the license plate 11 to move, ensuring that the license plate 11 slides stably on the surface of the slide rail 10. By setting the third buckle plate 45, only one license plate 11 enters the third buckle plate 45 at a time, avoiding the problem of the license plates 11 overlapping each other when the push plate 44 pushes the license plate 11, resulting in electronic writing errors or failure to write electronically.

[0043] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, two tightly fitting switching platforms 26 are provided at one end of the slide rail 10 away from the push plate 44, and the two switching platforms 26 are staggered in height and can slide laterally. Each switching platform 26 can be fitted and connected with the end of the slide rail 10, and the two switching platforms 26 are fixedly connected with a first buckle plate 28 on both sides away from each other, and the two switching platforms 26 are provided with a slide groove 30 on both sides close to each other. A second buckle plate 29 is slidably connected in each slide groove 30, and a group of springs 31 are provided between each second buckle plate 29 and the bottom of the corresponding slide groove 30. A reading support plate 21 is fixedly connected between the two side plates 24 and below the switching platform 26, and a reader 25 is fixedly connected to the reading support plate 21. A second support 17 is fixedly connected to one end of the bracket 14 close to the switching platform 26, and a second scanner 18 facing the switching platform 26 is fixedly connected to the second support 17.

[0044] By setting up the second scanner 18 and the reader 25, it is possible to check whether the electronically written information of the license plate 11 entering the switching platform 26 is accurate or whether the electronic writing fails. When an erroneous license plate 11 appears, the positions of the two switching platforms 26 can be swapped so that the empty switching platform 26 is connected to the end of the slide rail 10. This does not affect the subsequent continuous electronic writing processing. At the same time, the erroneous license plate 11 can be quickly ejected from the electronic writing processing area through the top plate 27, thereby automatically and efficiently eliminating erroneous license plates and improving the efficiency of electronic writing processing.

[0045] like Figure 4 and Figure 5 As shown, each first buckle plate 28 is arranged at an inclined angle with the switching platform 26, and each second buckle plate 29 has an inclined surface at the end, and the bottom of each second buckle plate 29 can be against the edge of another switching platform 26. A top plate 27 is embedded in the surface of each switching platform 26, and a group of electric drive cylinders 32 are fixedly connected to the bottom side of each switching platform 26 at a position corresponding to the top plate 27, and the extended end of each group of electric drive cylinders 32 passes through the switching platform 26 and is fixedly connected to the top plate 27.

[0046] By providing the first gusset plate 28 and the second gusset plate 29, when the license plate 11 enters the switching platform 26, it is also possible to prevent multiple license plates 11 from overlapping and affecting the recognition process. The two switching platforms 26 change their relative heights while switching positions to control the extension and retraction of the second gusset plate 29, so that the second gusset plate 29 no longer restricts the license plate 11 when the top plate 27 pushes out the wrong license plate 11.

[0047] The first clip plate 28 is set at an angle to the surface of the switching platform 26, and the first clip plate 28 is hooked on the outer edge of the license plate 11. When the top plate 27 pushes the license plate 11, the license plate 11 automatically flips to the outside of the device, thereby preventing the license plate 11 from falling on the electronic writing production line again and affecting the normal electronic writing work.

[0048] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a group of sliding rods 33 are fixedly connected to the bottom side of each switching platform 26 between the electric drive cylinders 32, and a slider 34 is slidably connected to each group of sliding rods 33. A screw rod 35 threadedly connected to the two sliders 34 is rotatably connected between the two side plates 24, and a first motor 36 is fixedly connected to the outer side of the side plate 24 at a position corresponding to the screw rod 35. The power output end of the first motor 36 is transmission-connected to the screw rod 35. Two guide plates 38 are fixedly connected between the two side plates 24 and below the switching platform 26. Two guide grooves 39 of different heights are opened on each guide plate 38, and both ends of each guide groove 39 have upwardly inclined parts. A sliding pin 37 is fixedly connected to the bottom of each switching platform 26 near the guide plate 38, and the end of each sliding pin 37 is slidably connected to the corresponding guide groove 39.

[0049] By setting a threaded connection between the screw rod 35 and the slider 34, the slider 34 is driven to move laterally with the switching platform 26, so that the switching platform 26 switches its position to eliminate the wrong license plate 11, and the switching platform 26 is guided by the guide groove 39 during the lateral movement, so that the height difference between the two switching platforms 26 changes, thereby changing the telescopic state of the two second buckle plates 29.

[0050] In this embodiment, initially, the operator connects the device to the power supply and the control system, and the operator puts the neatly arranged and stacked license plates 11 into the feed bin 12. Then, the second motor 40 is started through the control system to drive the rocker arm 41 to rotate. The rocker arm 41 and the connecting rod 42 are hinged to drive the push plate 44 to move back and forth, and the limit bar 47 can limit the movement of the push plate 44, ensuring that the push plate 44 always moves back and forth in a straight line.

[0051] During the reciprocating movement, the push plate 44 will push the license plate 11 in the feed bin 12 one by one between the two third buckle plates 45. The two third buckle plates 45 can only allow one license plate 11 to enter, which effectively avoids multiple license plates 11 overlapping above the electric writer 13 and affecting the electric writing work. After the license plate 11 enters between the two third buckle plates 45, the electric writer 13 is aligned with the license plate 11 and the first scanner 16 recognizes 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 writes it through the electric writer 13.

[0052] Then the push plate 44 reciprocates one stroke again to push the subsequent license plate 11 between the two third buckle plates 45 to continue the electronic writing work, and the license plate 11 that has been electronically written is pushed into the switching platform 26 by the subsequent license plate 11. At this time, one of the switching platforms 26 is attached and connected to the end of the slide rail 10, and the other switching platform 26 is located on one side of it and is higher than the switching platform 26 connected to the slide rail 10. The second buckle plate 29 in the switching platform 26 connected to the slide rail 10 is blocked and stored in the slide groove 30, and the second buckle plate 29 in the switching platform 26 not connected to the slide rail 10 is not blocked and extends out of the slide groove 30 under the thrust of the spring 31. The extended second buckle plate 29 and the first buckle plate 28 opposite to it work together to also have the effect of allowing only one license plate 11 to enter the switching platform 26, thereby avoiding the overlapping of the license plates 11 affecting the recognition effect.

[0053] When the electronically written license plate 11 enters the switching platform 26, the second scanner 18 identifies the tag information of the license plate 11 and uploads it to the control system. At the same time, the reader 25 reads the electronically written information of the license plate 11 and uploads it to the control system. The control system compares and verifies. If the verification is correct, the switching platform 26 does not switch 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 verification information is incorrect or the electronically written information cannot be read, the control system starts the first motor 36 to drive the screw rod 35 to rotate, so that the slider 34 drives the two switching platforms 26 to switch positions quickly, and the switching platform 26 with the wrong license plate 11 is disconnected from the slide rail 10, and the wrong license plate 11 is moved out of the electronically written production line, while the empty switching platform 26 is connected to 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 into the production line again for verification, so that automatic, continuous and efficient electronic writing production and verification work can be realized, thereby improving production efficiency.

[0055] During the process of switching positions of the two switching platforms 26, the two switching platforms 26 will move along the trajectory of the guide groove 39. During this process, the switching platform 26 that does not carry the wrong license plate 11 will descend along the inclined part of the guide groove 39, thereby reducing the height. The inclined surface of the originally extended second buckle plate 29 squeezes and slides with the switching platform 26, so that the originally extended second buckle plate 29 retracts into the slide groove 30, and the switching platform 26 carrying the wrong license plate 11 will be lifted upward along the trajectory of the guide groove 39 at the end of the lateral movement. Then, the second buckle plate 29 in this switching platform 26 is no longer blocked and extends out under the thrust of the spring 31, and works together with the first buckle plate 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.
