Description

Technical Field

[0001] This utility model relates to the field of license plate processing technology, and in particular to an automatic license plate feeding mechanism. Background Technology

[0002] License plates, also known as vehicle license plates, are plates that are hung on the front and rear of a vehicle. They are usually made of aluminum, iron, plastic, or paper and are engraved with the vehicle's registration number, registration area, or other relevant information. Their main function is to indicate the region where the vehicle belongs and to find the owner and registration information of the vehicle through the license plate.

[0003] During license plate processing, the plates need to be placed on the loading mechanism and wait for the handling mechanism to pick them up and send them to the designated area for lettering. The existing loading methods mostly involve manually placing stacks of plates one by one onto the loading mechanism, which is inefficient and the height, position and time interval cannot be consistent, making it difficult for the handling mechanism to pick them up accurately and affecting subsequent assembly line operations. In order to address this technical problem, this application proposes an automatic license plate loading mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic license plate loading mechanism. This mechanism uses a motor to drive a lead screw sleeve to rotate. The precise threaded structure between the lead screw sleeve and the lead screw meshes, causing the lead screw to move up and down. This, in turn, causes a movable plate fixed to the lead screw to move up and down. Under the action of a push rod, the placement plate pushes the plate placed on it upwards. Furthermore, a control component ensures that the plate reaches the same height each time, facilitating precise gripping by the handling mechanism and ensuring uninterrupted assembly line operation in subsequent processes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

Four push rods are fixedly connected to the bottom of the placement plate. The push rods pass through four through holes in the base and are fixedly connected to a lower movable plate. A driving component is provided at the lower end of the movable plate.

[0007] Furthermore, the clamping assembly includes two clamping rods fixedly connected by a connecting rod. The clamping rods are connected to a fixed plate located at the top of the base by a pin. A pneumatic telescopic rod is connected to the lower end of the clamping rod.

[0008] Furthermore, the drive assembly includes a lead screw fixedly connected to the bottom end of the moving plate via a flange, the lead screw being inserted into a motor with a lead screw sleeve.

[0009] Furthermore, a limit sensor is provided at the bottom end of the lead screw, and the limit sensor is electrically connected to the motor.

[0010] Furthermore, four fixing columns are fixedly connected to the bottom of the base, and a motor mounting plate is fixedly connected to the fixing columns. A long rod is fixedly connected to the bottom of the motor mounting plate, and an upper limit sensor and a lower limit sensor are provided at the upper and lower ends of the long rod. The limit sensors are electrically connected to the motor.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 An embodiment of this utility model provides an automatic license plate feeding mechanism, including a base 1. Two limiting posts 2 are fixedly connected to the upper side of the top of the base 1. The limiting posts 2 are connected by a mounting frame 3. A control component is fixedly connected to the mounting frame 3. Adjusting posts 4 are respectively provided on the left and right sides of the top of the base 1. Adjusting post base 5 is fixedly connected to the bottom of the adjusting post 4. The adjusting post base 5 has a threaded round hole. A clamping component is provided on the lower side of the top of the base 1, including two clamping rods 10 fixedly connected by connecting rods 9. The clamping rods 10 are connected to a fixed plate 11 located at the top of the base 1 by a pin. A pneumatic telescopic rod 12 is connected to the lower end of the clamping rods 10. A placement plate 6 is provided on the upper end of the base 1. Four pushing rods 7 are fixedly connected to the bottom end of the placement plate 6. The pushing rods 7 pass through the four through holes opened in the base 1 and are fixedly connected to the lower moving plate 8. A driving component is provided on the lower end of the moving plate 8, including a lead screw 13 fixedly connected to the bottom end of the moving plate 8 by a flange. The lead screw 13 is inserted into a motor 14 with a lead screw sleeve.

[0024] Specifically, the motor 14 drives the lead screw sleeve to rotate, and the precision thread structure between the lead screw sleeve and the lead screw 13 meshes with each other, driving the lead screw 13 to move up and down, thereby driving the moving plate 8 fixed to it to move up and down. Under the action of the push rod 7, the placement plate 6 pushes the plate placed on it upward, and through the control component, it is ensured that the height position of the plate is the same each time, which is convenient for the handling mechanism to grasp accurately and does not affect the assembly line operation of subsequent processes. Two limit posts 2 are fixedly connected to the top of the base 1 to limit the long side direction of the plate. Adjustment posts 4 are respectively set on the left and right sides of the top of the base 1. The adjustment posts 4 are fixed in the corresponding positions by using screws and can be finely adjusted to constrain the short side direction of the plate. By pulling the handle 23, the pneumatic telescopic rod 12 connected to it can be moved, thereby driving the clamping rod 10 to rise, clamping the stacked plates, preventing tilting and collapse, and ensuring that the position does not shift during the upward movement of the plates.

[0025] The base 1 has four fixed posts 16 fixedly connected to its bottom end. The fixed posts 16 are fixedly connected to the motor mounting plate 17. The motor mounting plate 17 has a long rod 18 fixedly connected to its bottom end. The long rod 18 has an upper limit sensor 19 and a lower limit sensor 20 at its upper and lower ends. The limit sensors are electrically connected to the motor 14. The bottom end of the moving plate 8 is fixedly connected to a lead screw 13 through a flange. The lead screw 13 is inserted into the motor 14 with a lead screw sleeve. The bottom end of the lead screw 13 is provided with a limit sensor 15. The limit sensor is electrically connected to the motor 14.

[0026] Specifically, the limit sensor 15 at the bottom of the lead screw 13, in conjunction with the upper limit sensor 19 and lower limit sensor 20 of the long rod, can constrain the top and bottom reaches of the placement plate. When the limit sensor 15 at the bottom and the lower limit sensor 20 trigger an electrical signal, the lead screw 13 stops moving downwards. At this time, the placement plate 6 stops at the origin at the top of the base, and the worker can stack the boards on the placement plate 6. After the conveying mechanism grabs the first board, the control component sends a signal to drive the motor 14 to move forward, and the lead screw 13 moves upwards until the limit sensor 15 at the bottom of the lead screw 13 and the upper limit sensor 19 trigger an electrical signal, and the lead screw 13 stops moving upwards. At this time, the boards on the placement plate 6 have been grabbed. The control component sends a signal to drive the motor 14 to move in the reverse direction, and the lead screw 13 moves downwards, which can make the placement plate 6 return to the origin to reload, thereby ensuring the continuity of automatic loading.

[0027] Working principle: In use, pull handle 23 to lower clamping rod 10. The worker places the stacked boards on the placement plate 6, and pull handle 23 again to clamp clamping rod 10, clamping the stacked boards to prevent tilting and collapse, and ensuring that the boards do not shift position during upward movement. At the same time, start motor 14, which drives the lead screw sleeve to rotate. The precision thread structure between the lead screw sleeve and the lead screw 13 meshes, driving the lead screw 13 to move up and down, thereby driving the movable plate 8 fixed to it to move up and down. Under the action of 7, the placement plate 6 pushes the board placed on it upwards, and through the control component, it ensures that the height position of the board is the same each time, which is convenient for the handling mechanism to grasp accurately and does not affect the subsequent assembly line operation. The limit sensor 15 set at the bottom of the lead screw 13, together with the upper limit sensor 19 and the lower limit sensor 20 of the long rod, can constrain the top and bottom reached by the movement of the placement plate 6. After the placement plate 6 reaches the top and clears the board placed on it, it can return to the origin to reload, thereby ensuring the continuity of automatic feeding.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
