Description

Technical Field

[0001] The utility model relates to the field of motor vehicle license plate production, and particularly to a selection character mold device for a batch license plate production machine. Background Art

[0002] Currently, the production of license plate numbers is an important link in the vehicle management agency's issuance of vehicle license plates. Traditional license plate production methods generally adopt manual or semi-automatic operations. In this mode, since each license plate number is unique, the manufacturer needs to manually arrange the corresponding character molds on the stamping machine tool according to the number of each license plate, and then stamp the blank plate. This operation method not only has low efficiency, but also is prone to quality problems such as skewed fonts, uneven character spacing, and inconsistent depths, which is time-consuming and laborious.

[0003] In order to improve the automation degree and stamping quality of license plate production, a single-character stamping device has been proposed in the prior art, such as the technology disclosed in the Chinese patent with the authorization announcement number CN210363030U. The device includes a character mold module, a moving module, and a stamping module. The character mold module stores a plurality of concave character molds and a plurality of convex character molds corresponding to the concave character molds. The stamping module is provided with a first clamping position and a second clamping position for adapting and installing the convex character mold and the concave character mold respectively. The moving module is used to automatically feed or discharge the required convex character mold and concave character mold into or out of the corresponding clamping positions of the stamping module. In this way, the stamping module can automatically stamp the corresponding single character on the plate to be stamped, thereby realizing the automatic stamping of license plate numbers, improving the license plate production efficiency and ensuring the stamping quality.

[0004] However, although the above single-character stamping device realizes automatic operation, its basic working principle is that only one single-character mold can be selected and stamped at a time. Considering that a standard license plate number usually contains 6 to 7 characters, this means that for each license plate produced, the device needs to repeat 6 to 7 independent character mold selections. The frequent replacement of character molds takes up a considerable amount of time, resulting in room for improvement in the overall production efficiency. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a selection character mold device for a batch license plate production machine, so as to achieve the purpose of improving production efficiency.

[0006] To solve the above technical problems, the technical solution of the present utility model is: a character mold selection device for a batch license plate making machine, including a frame, on which an upper support frame and a lower support frame are fixedly connected. The lower support frame is located below the upper support frame and is correspondingly arranged with the upper support frame. There is a gap between the upper support frame and the lower support frame. The upper support frame is connected with a plurality of upper partition plates along its length direction. An upper accommodation cavity is formed between adjacent upper partition plates. The lower support frame is connected with a plurality of lower partition plates along its length direction. A lower accommodation cavity is formed between adjacent lower partition plates. A set of character mold groups is arranged in each lower accommodation cavity. An adjusting mechanism for pushing the character mold group to move towards the upper accommodation cavity is arranged on the frame and / or the upper support frame and / or the lower support frame. Each lower accommodation cavity corresponds to an adjusting mechanism. The height of the gap is greater than the thickness of one character module and less than the thickness of two character modules.

[0007] To implement the above technical solution, first, a series of pre-set character mold groups are prepared. Each character mold group contains all concave character modules or all convex character modules required to complete a standard license plate. All concave character modules or all convex character modules are orderly stacked and stored in the lower accommodation cavities of the lower support frame. When the system receives a license plate making instruction, the corresponding adjusting mechanism is activated. This adjusting mechanism precisely pushes the character mold group upward. During the upward movement of the character mold group, the selected character modules are located in the gap reserved between the upper support frame and the lower support frame. Subsequently, a push plate is passed through the gap, and all the selected character modules can be pushed out of the gap to the designated position at one time, thus preparing for the subsequent synchronous stamping operation. This parallel selection mechanism greatly reduces the number and time-consuming of character mold replacement and plate shifting during the production of a single license plate, fundamentally solving the efficiency bottleneck caused by the cumbersome repetition operation cycle of the existing single-character stamping device.

[0008] As a preferred solution of the present utility model, the upper support frame is provided with a plurality of upper observation slots corresponding to the upper partition plates, and the upper observation slots communicate with the upper accommodation cavity.

[0009] To implement the above technical solution, the plurality of upper observation slots provided on the upper support frame allow operators or automated vision systems to monitor and confirm the final positioning state of the character modules in real time; it also has the function of reducing the weight of the structure, contributing to the overall light weight of the equipment.

[0010] As a preferred solution of the present utility model, the lower support frame is provided with a plurality of lower observation slots corresponding to the lower partition plates, and the lower observation slots communicate with the lower accommodation cavity.

[0011] To implement the above technical solution, the plurality of upper observation slots provided on the upper support frame allow operators or automated vision systems to monitor and confirm the final positioning state of the character modules in real time; it also has the function of reducing the weight of the structure, contributing to the overall light weight of the equipment.

[0012] As a preferred solution of the present invention, a reinforcement frame is connected to the outer wall of the upper support frame, the reinforcement frame surrounds the upper support frame, the reinforcement frame is fixed to the frame through a support frame, and the reinforcement frame is close to the gap.

[0013] The above technical solution implements the fixed connection between the reinforcement frame and the frame, providing continuous external support and restraint to the upper support frame. This continuous structural support ensures that the upper support frame maintains its structural integrity and positioning accuracy throughout the entire stamping cycle, especially when the character module passes through the gap below it, thus providing a stable foundation for the precise positioning of the character module and subsequent stamping.

[0014] As a preferred solution of the present invention, a fixing plate is fixedly connected to the frame, a reinforcing plate is fixedly connected to the fixing plate, the reinforcing plate surrounds the outer wall of the lower support frame, and the side wall of the reinforcing plate is used to interfere with the outer wall of the lower support frame.

[0015] In implementing the above technical solution, when the letterform assembly within the lower support frame is pushed upward by the adjustment mechanism, the lower support frame is subjected to various operating forces and potential impact forces. At this time, the reinforcement plate surrounding and contacting the outer wall of the lower support frame, through its secure connection with the fixed plate and the frame, continuously provides enhanced structural support and rigid restraint for the lower support frame.

[0016] As a preferred solution of the present invention, two reinforcing plates are provided and are respectively located at both ends of the fixed plate, and the length direction of the reinforcing plates is arranged along the height direction of the lower support frame.

[0017] To implement the above technical solution, when the adjustment mechanism pushes the character module group to move up and down in the lower accommodating cavity of the lower support frame, the two reinforcement plates effectively suppress the overall bending or local deformation that may occur in the lower support frame when subjected to force through the interference with the outer wall of the lower support frame, thereby ensuring the precise shape and position of the lower accommodating cavity, and further ensuring the smooth movement and precise alignment of the character module group in the lower accommodating cavity, as well as the accuracy of the character modules when they are launched in batches.

[0018] As a preferred solution of the present invention, weight-reducing grooves are provided on both the upper partition and the lower partition.

[0019] The above technical solution is implemented by creating weight-reducing slots in the upper and lower partitions, achieving a lightweight design for the entire device. While maintaining the necessary rigidity and separation function of the partitions, the material usage and weight of the partitions themselves are effectively reduced.

[0020] As a preferred embodiment of the present utility model, the adjusting mechanism includes an adjusting motor, a support plate, a sliding rod, and a rotating rod. The sliding rod is fixed to the frame, and the length direction of the sliding rod is arranged along the height direction of the lower support frame. The rotating rod is rotatably connected to the frame, and the axis of the sliding rod is parallel to the axis of the rotating rod. The support plate is slidably connected to the sliding rod and threadedly connected to the rotating rod. The support plate supports the character module group, and the adjusting motor drives the rotating rod to rotate through a connecting component.

[0021] To achieve the above technical solution, the rotational torque of the adjusting motor is transmitted to the rotating rod through the connecting component, driving the rotating rod to rotate around its axis. Since the support plate is threadedly connected to the rotating rod, the rotation of the rotating rod will force the support plate to perform a linear motion along the axial direction of the rotating rod. At the same time, the sliding connection between the support plate and the sliding rod ensures the stability and accuracy of the direction of the support plate during the linear motion.

[0022] As a preferred embodiment of the present utility model, the connecting component includes a first connecting wheel, a second connecting wheel, and a connecting belt. The motor shaft of the adjusting motor is fixedly connected to the first connecting wheel, the second connecting wheel is fixedly connected to the rotating rod, and the first connecting wheel causes the second connecting wheel to rotate through the connecting belt.

[0023] To achieve the above technical solution, through the coordinated action of the first connecting wheel, the second connecting wheel, and the connecting belt, the efficient, stable, and flexible transmission of the power of the adjusting motor to the rotating rod is realized. This connecting belt transmission method has inherent shock absorption and buffering characteristics, which can effectively absorb the impact and vibration when the adjusting motor starts and stops, thereby reducing noise, protecting key components such as the adjusting motor and the rotating rod, and extending their service life. At the same time, by adjusting the diameters of the first connecting wheel and the second connecting wheel, the transmission ratio can be flexibly configured to adapt to different torque and speed requirements, improving the adaptability and adjustability of the device.

Detailed implementation manners

[0030] The following further details the specific implementation manners of the present utility model in conjunction with the accompanying drawings, so that the technical solutions of the present utility model are easier to understand and master.

[0031] A character mold selection device for a batch license plate making machine includes a frame 1, on which an upper support frame 2 and a lower support frame 3 are fixedly connected. The upper support frame 2 and the lower support frame 3 are both vertically arranged. The lower support frame 3 is located directly below the upper support frame 2 and is correspondingly arranged with the upper support frame 2. There is a gap 27 between the upper support frame 2 and the lower support frame 3.

[0032] The upper support frame 2 is fixedly connected with a plurality of upper partition plates 4 along its own length direction, and an upper accommodation cavity is formed between two adjacent upper partition plates 4; upper positioning holes 5 are opened on the inner wall of the upper support frame 2, and first convex parts 6 are integrally connected to both ends of the upper partition plate 4. The first convex parts 6 are embedded into the upper positioning holes 5 to realize the fixed connection between the upper support frame 2 and the upper partition plate 4.

[0033] The lower support frame 3 is fixedly connected with a plurality of lower partition plates 7 along its own length direction, and a lower accommodation cavity is formed between two adjacent lower partition plates 7. Lower positioning holes 8 are opened on the inner wall of the lower support frame 3, and second convex parts 9 are integrally connected to both ends of the lower partition plate 7 respectively. The second convex parts 9 are embedded into the lower positioning holes 8 to realize the fixed connection between the lower support frame 3 and the lower partition plate 7.

[0034] Therefore, there are a plurality of upper accommodation cavities and lower accommodation cavities.

[0035] Weight reduction grooves 10 are opened on both the upper partition plate 4 and the lower partition plate 7. The weight reduction grooves 10 on the upper partition plate 4 are arranged along the length direction of the upper partition plate 4; the weight reduction grooves 10 on the lower partition plate 7 are arranged along the length direction of the lower partition plate 7.

[0036] A set of character modules is arranged in each lower accommodation cavity. Each set of character modules includes all concave character modules 11 or all convex character modules 11 required to complete a standard license plate. The height of the gap 27 is greater than the thickness of one character module 11 and less than the thickness of two character modules 11.

[0037] Therefore, in order to stamp a license plate from a sheet metal, two of these selected die devices are required. A concave die module group is placed on one selected die device, and a convex die module group is placed on the other selected die device.

[0038] An adjusting mechanism 12 for pushing the die module group to move closer to the upper accommodating cavity is provided on the frame 1. Each lower accommodating cavity corresponds to an adjusting mechanism 12.

[0039] The adjusting mechanism 12 includes an adjusting motor 13, a support plate 14, a sliding rod 15, and a rotating rod 16. The sliding rod 15 is fixed to the frame 1, and the length direction of the sliding rod 15 is arranged along the height direction of the lower support frame 3, that is, the sliding rod 15 is vertically arranged. The rotating rod 16 is rotatably connected to the frame 1, and the axis of the sliding rod 15 is parallel to the axis of the rotating rod 16. The support plate 14 is slidably connected to the sliding rod 15 and is threadedly connected to the rotating rod 16. The rotating rod 16 is a lead screw.

[0040] The adjusting motor 13 drives the rotating rod 16 to rotate through a connection assembly 17. The connection assembly 17 includes a first connecting wheel 18, a second connecting wheel 19, and a connecting belt 20. The motor shaft of the adjusting motor 13 is fixedly connected to the first connecting wheel 18, and the first connecting wheel 18 is coaxially arranged with the motor shaft. The second connecting wheel 19 is fixedly connected to the rotating rod 16, and the second connecting wheel 19 is coaxially arranged with the rotating rod 16. The first connecting wheel 18 causes the second connecting wheel 19 to rotate through the connecting belt 20. The first connecting wheel 18 and the second connecting wheel 19 are gears, and the connecting belt 20 is a toothed belt. The connecting belt 20 is tensioned by the first connecting wheel 18 and the second connecting wheel 19.

[0041] When the adjusting motor 13 is started, the motor shaft rotates, and the first connecting wheel 18 causes the rotating rod 16 to rotate through the connecting belt 20, so that the support plate 14 moves along the length direction of the sliding rod 15. The support plate 14 pushes the die module group along the lower support frame 3 in the direction close to the upper support frame 2, so that the selected die module 11 in the die module group is located in the gap 27. Since each lower accommodating cavity corresponds to an adjusting mechanism 12, all the selected die modules 11 can be located in the gap 27 in a very short time.

[0042] By moving the push plate 28 along the length direction of the frame 1, all the die modules 11 located in the gap 27 can be pushed out simultaneously, so as to greatly improve the production efficiency. [[ID=!7]]

[0043] A plurality of upper observation slots 21 are provided in the upper support frame 2. One upper observation slot 21 corresponds to one upper partition plate 4, and the upper partition plate 4 is located in the middle of the upper observation slot 21. The upper observation slot 21 communicates with the upper accommodating cavity.

[0044] A plurality of lower observation slots 22 are provided in the lower support frame 3. One lower observation slot 22 corresponds to the lower partition plate 7, and the lower observation slot 22 communicates with the lower accommodating cavity.

[0045] A reinforcing frame 23 is fixedly connected to the outer wall of the upper support frame 2, and the reinforcing frame 23 surrounds the upper support frame 2. The reinforcing frame 23 is fixed to the machine frame 1 through a support frame 26, and the reinforcing frame 23 is close to the gap 27.

[0046] A vertically arranged fixing plate 24 is fixedly connected to the machine frame 1, and the two fixing plates 24 are respectively located on both sides of the lower support frame 3. A reinforcing plate 25 is fixedly connected between the two fixing plates 24. The reinforcing plate 25 surrounds the outer wall of the lower support frame 3, and the side wall of the reinforcing plate 25 is used to abut against the outer wall of the lower support frame 3.

[0047] There are two reinforcing plates 25, which are respectively located at both ends of the fixing plate 24.

[0048] Of course, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
