Description

Technical Field

[0001] This invention relates to license plate manufacturing equipment, and more particularly, to a multi-specification license plate manufacturing machine. Background Technology

[0002] Currently, with the automation development of vehicle license plate production technology, related manufacturing equipment is also constantly being updated. For example, Chinese patent application publication number CN120348094A discloses a batch license plate production machine. This equipment mainly uses multiple first and second lifting mechanisms arranged side by side on the frame to store and select punch and die sets, respectively. The selected molds are transported to the stamping station using first and second push plates, and finally, the pressing plate pushes the lifting plate to complete the stamping of the blank. This design, through automated mold selection and independent lifting and conveying, improves production efficiency to a certain extent and reduces mold storage space.

[0003] However, this technical solution has significant limitations in practical applications. Because the multiple lifting mechanisms responsible for providing the letter molds are installed side-by-side on the frame at fixed intervals, the physical positions of each letter mold group are relatively fixed. During license plate production, the selected molds can only be arranged according to this fixed equipment structure spacing, i.e., only in a long strip arrangement. This limits the equipment to producing only a single size of license plate, severely restricting its versatility and practicality. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a multi-specification license plate production machine to improve the versatility and practicality of the equipment.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a multi-specification license plate making machine, comprising a frame, a lower mold frame, and an upper mold frame located above the lower mold frame. The upper mold frame has an upper placement slot for placing upper serial number characters, and the lower mold frame has a lower placement slot for placing lower serial number characters. The upper placement slot and the lower placement slot correspond to each other. A molding mechanism is connected to the frame. The lower mold frame has a first lower connecting slot and a second lower connecting slot. The first lower connecting slot is located to the side of the lower placement slot, and the second lower connecting slot is located at the lower placement slot. On the front or rear side, the first lower connecting groove and the second lower connecting groove are used to selectively install the lower province and city characters. The upper mold frame is provided with a first upper connecting groove and a second upper connecting groove. The first upper connecting groove and the second upper connecting groove are used to selectively install the upper province and city characters. The first lower connecting groove corresponds to the first upper connecting groove, and the second lower connecting groove corresponds to the second upper connecting groove. A first license plate placement area is formed between the first lower connecting groove and the lower placement groove, and a second license plate placement area is formed between the second lower connecting groove and the lower placement groove. A drive mechanism is provided on the frame. The driving mechanism moves the lower mold frame closer to the molding mechanism while simultaneously moving the upper mold frame closer to the lower mold frame, or the driving mechanism moves the lower mold frame further away from the molding mechanism while simultaneously moving the upper mold frame further away from the lower mold frame.

[0006] To achieve the above technical solution, the lower mold frame and the upper mold frame move synchronously through a drive mechanism. When producing a license plate of the first specification, the lower province / city character mold is installed in the first lower connecting groove, and the upper province / city character mold is installed in the first upper connecting groove. At this time, the first lower connecting groove and the lower placement groove cooperate to form a horizontally extending first license plate placement area. When producing a license plate of the second specification, the lower province / city character mold is installed in the second lower connecting groove, and the upper province / city character mold is installed in the second upper connecting groove. At this time, the second lower connecting groove and the lower placement groove cooperate to form a vertically extending second license plate placement area. As the drive mechanism moves the lower mold frame closer to the molding mechanism, it simultaneously drives the upper mold frame to move closer to the lower mold frame to complete the mold closing preparation; conversely, when moving away from the molding mechanism, the mold opens. By setting a first lower connecting groove, a second lower connecting groove, and corresponding first upper connecting groove and second upper connecting groove in different positions on the lower mold frame and the upper mold frame, the relative positions of the province and city characters and the serial number characters can be flexibly adjusted according to requirements, thus enabling the stamping production of two different specifications of license plates on the same machine and effectively improving the versatility of the equipment.

[0007] In a preferred embodiment of the present invention, a support base is connected to the frame, and the support base is provided with a placement area for storing the lower serial number character mold, the upper serial number character mold, the upper province / city character mold, and the lower province / city character mold, and the molding mechanism is disposed on the support base.

[0008] By implementing the above technical solution, the integrated placement area on the support base can centrally store the lower serial number font, the upper serial number font, the upper province / city font, and the lower province / city font. This not only optimizes the overall layout of the equipment but also makes the structure more compact.

[0009] In a preferred embodiment of the present invention, the driving mechanism includes a driving rod, a sliding rod, a separating plate, and a separating component. The driving rod is rotatably connected to the frame, the sliding rod is connected to the frame, the lower mold frame is threadedly connected to the driving rod and slidably connected to the sliding rod, the axis of the sliding rod is parallel to the axis of the driving rod, the sliding rod extends toward the molding mechanism, the separating plate is connected to the frame, the separating plate has a separating inclined surface, and the separating component is connected to the upper mold frame and is used to slide along the separating inclined surface.

[0010] To achieve the above technical solution, the drive rod rotates on the frame, using a threaded transmission to drive the lower mold frame to move axially along the slide rod. During the movement of the upper mold frame driven by the lower mold frame, the separating component connected to the upper mold frame slides along the separating ramp of the separating plate fixed to the frame. When the separating component slides to the high end of the separating ramp, it forces the upper mold frame to rise relative to the lower mold frame, achieving automatic mold opening; when the separating component slides to the low end of the separating ramp, the upper mold frame, under gravity or guiding force, approaches the lower mold frame, achieving automatic mold closing. By utilizing the horizontal feed motion of the lower mold frame, combined with the inclined guiding action of the separating plate and the separating component, it is converted into the vertical opening and closing motion of the upper mold frame. This eliminates the need for a separate lifting power source for the upper mold frame, simplifying the mechanical structure and reducing energy consumption.

[0011] In a preferred embodiment of the present invention, a guide rod is connected to the upper mold frame, and a guide groove is provided on the lower mold frame, wherein the guide rod is slidably connected in the guide groove.

[0012] To achieve the above technical solution, during the process of the upper mold frame covering the lower mold frame, the guide rod connected to the upper mold frame is constrained by the guide groove opened on the lower mold frame, and is forced to slide and flip along a direction perpendicular to the height of the lower mold frame. This forcibly corrects the movement trajectory of the upper mold frame, ensuring that the upper mold frame can be pressed flat and without angles onto the license plate placed on the lower mold frame. This effectively avoids the problem of uneven force or deformation of the license plate caused by the angle between the upper and lower mold frames, and significantly improves the flatness and finished product quality of the license plate pressing.

[0013] As a preferred embodiment of the present invention, the lower mold frame is connected with a plurality of first positioning posts, a plurality of common positioning posts, and a plurality of second positioning posts. The plurality of first positioning posts and the plurality of common positioning posts form a first license plate placement area, and the plurality of second positioning posts and the plurality of common positioning posts form a second license plate placement area.

[0014] To achieve the above technical solution, several common positioning posts are used as references on the lower die frame. When producing a license plate of the first specification, several first positioning posts, in conjunction with the common positioning posts, enclose the first license plate placement area, limiting the position of the elongated blank. When producing a license plate of the second specification, several second positioning posts, in conjunction with the common positioning posts, enclose the second license plate placement area, limiting the position of the square blank. By reusing the common positioning posts, the structural layout of the lower die frame surface is simplified, enabling rapid and accurate positioning of license plate blanks of different shapes, ensuring the accuracy of the stamped font position.

[0015] In a preferred embodiment of the present invention, the support base is provided with a molding groove, and the molding mechanism includes a molding screw, a molding sleeve and a molding plate. The molding screw is rotatably connected to the support base, the molding sleeve is slidably connected to the molding groove, the molding screw is threadedly connected to the molding sleeve, the molding plate is connected to the molding sleeve, and a molding area is formed between the molding plate and the inner wall of the molding groove.

[0016] To achieve the above technical solution, the rotating molding screw drives the threaded molding sleeve to slide up and down relative to the frame, thereby causing the molding plate connected to the molding sleeve to move vertically upward, applying pressure to the upper and lower mold frames in the molding groove. The rotational motion is converted into strong vertical pressure through screw transmission, which can stably and evenly press the molding plate against the upper and lower mold frames, ensuring that the depth and clarity of the license plate stamping meet the standards.

[0017] In a preferred embodiment of the present invention, a longitudinal frame is connected to the frame, a transverse frame is slidably connected to the longitudinal frame along its length, a vertical frame is slidably connected to the transverse frame along its length, and a mounting frame and a clamping frame are slidably connected to the vertical frame along its height. A suction cup for picking up license plates is connected to the mounting frame, and a gripper for clamping the lower serial number character mold, the upper serial number character mold, the upper province / city character mold, and the lower province / city character mold is slidably connected to the clamping frame.

[0018] To achieve the above technical solution, a three-axis linkage automated gripping system is constructed by sliding the horizontal frame on the vertical frame, the vertical frame on the horizontal frame, and the mounting frame and clamping frame on the vertical frame. The suction cups on the mounting frame are responsible for picking up and placing the license plates to be processed or already processed, while the grippers on the clamping frame are specifically used for gripping and replacing the lower serial number mold, upper serial number mold, upper province / city mold, and lower province / city mold. This achieves complete automation of license plate loading / unloading and mold changing, greatly reducing manual labor intensity and improving the continuity and safety of the production process.

[0019] In a preferred embodiment of the present invention, a plurality of limiting rods are connected to the frame, and a first push plate and a second push plate are slidably connected to the frame. The first push plate and the plurality of limiting rods form a first storage area for placing a first license plate, and the second push plate and the plurality of limiting rods form a second storage area for placing a second license plate.

[0020] To achieve the above technical solution, a first and second push plate are installed on the frame, each working in conjunction with several limiting rods to create independent first and second storage areas. During production, the first push plate can push finished license plates of the first specification to be neatly stacked in the first storage area, while the second push plate can push finished license plates of the second specification to be stacked in the second storage area. This achieves the classified collection and organization of finished license plates of different specifications, avoiding confusion among finished products.

[0021] As a preferred embodiment of the present invention, a tray for placing license plates is connected to the frame, a heating plate corresponding to the tray is connected to the frame, a hot stamping area is formed between the tray and the heating plate, the end of the longitudinal frame away from the molding mechanism extends towards the hot stamping area, and an unwinding roller for supporting the hot stamping film roll and a winding roller for winding up waste film are rotatably connected to the frame.

[0022] To achieve the above technical solution, the working range of the gripping system is extended to cover the hot stamping area through the longitudinal frame extension design. Suction cups transport the stamped license plate to a tray, where a heating plate hot stamps the lettering on the license plate surface. Simultaneously, the unwinding and rewinding rollers work together to automatically transport the hot stamping film and collect waste. Integrating the stamping and hot stamping processes into a single machine reduces the time the license plate spends transferring between different machines, significantly improving the overall efficiency of license plate production.

[0023] In a preferred embodiment of the present invention, the tray is slidably connected to the frame, and a peeling member is slidably connected to the frame. The peeling member moves along the length of the heating plate and passes between the hot stamping film and the license plate to separate the hot stamping film from the license plate.

[0024] To achieve the above technical solution, after hot stamping, the peeling part moves along the length of the heating plate and passes between the hot stamping film and the license plate, so that the hot stamping film is separated from the surface of the license plate, ensuring the surface quality and aesthetics of the finished license plate.

[0025] In summary, the present invention has the following beneficial effects: 1. By setting up two sets of mold installation positions, namely the first connecting groove and the second connecting groove, the limitation of fixed character mold arrangement in traditional equipment is broken. It can flexibly switch between producing single-layer rectangular and double-layer square license plates on one machine, thereby reducing equipment investment costs.

[0026] 2. By utilizing the inclined surfaces of the separation plate and the separation component, the horizontal feed motion of the lower mold frame enables the automatic vertical opening and closing of the upper mold frame, eliminating the need for an additional lifting drive device, thus simplifying the mechanical structure and improving operational stability.

[0027] 3. It integrates a three-axis robotic arm system, which not only realizes the automatic loading and unloading of license plate blanks, but also the automatic gripping and replacement of letter molds, greatly improving production efficiency.

[0028] 4. The stamping and hot stamping processes are integrated into one, and a special peeling part is provided to ensure the quality of hot stamping separation. With the help of a precise guiding and positioning mechanism, a high yield rate of license plate production is guaranteed. Attached Figure Description

[0051] The lower mold frame 21 is connected to several first positioning posts 40, several common positioning posts 41, and several second positioning posts 42. The several first positioning posts 40 and several common positioning posts 41 form a first license plate placement area 36; the several second positioning posts 42 and several common positioning posts 41 form a second license plate placement area 37.

[0052] The upper ends of the first positioning post 40, the common positioning post 41, and the second positioning post 42 are all provided with guide slopes 43.

[0053] A limiting and guiding mechanism 44 is provided between the lower mold frame 21 and the upper mold frame 20. The limiting and guiding mechanism 44 includes a guide groove 45 and a guide rod 46. A guide block 47 is fixedly connected to the upper surface of the lower mold frame 21 by bolts. The guide groove 45 is formed on the guide block 47, and its length direction is set along the height direction of the lower mold frame 21. The guide rod 46 is threaded to the side wall of the upper mold frame 20 and slidably connected in the guide groove 45. The guide rod 46 is cylindrical. The guide groove 45 is an oblong groove. The guide rod 46 is placed horizontally.

[0054] A drive mechanism 48 is provided on the frame 1. The drive mechanism 48 drives the lower mold frame 21 to move closer to the molding mechanism 10 while simultaneously moving the upper mold frame 20 closer to the lower mold frame 21. Alternatively, the drive mechanism 48 drives the lower mold frame 21 to move away from the molding mechanism 10 while simultaneously moving the upper mold frame 20 away from the lower mold frame 21.

[0055] The drive mechanism 48 includes a drive rod 49, a slide rod 50, a separation plate 51, and a separation component 52. The drive rod 49 is horizontally positioned and rotatably connected to the frame 1. The drive rod 49 is driven by a servo motor, which is fixed to the frame 1. The drive rod 49 is a lead screw. The slide rod 50 is connected to the frame 1, and the axis of the slide rod 50 is parallel to the axis of the drive rod 49. A displacement block 53 is fixedly connected to the lower end of the lower mold frame 21. The displacement block 53 is threadedly connected to the drive rod 49 and slidably connected to the slide rod 50.

[0056] The slide bar 50 extends toward the molding mechanism 10. The separation plate 51 is connected to the frame 1, and the two separation plates 51 are located on the left and right sides of the upper mold frame 20, respectively. A separation slope 54 is provided on the separation plate 51, and the separation member 52 is fixedly connected to the side wall of the upper mold frame 20 and is used to slide along the separation slope 54.

[0057] The drive mechanism 48 drives the lower mold frame 21 and the upper mold frame 20 to be placed in the molding area 14. The lower mold frame 21 corresponds to the molding plate 13, and the upper mold frame 20 corresponds to the support base 2.

[0058] Two stabilizing guide rails 55 are fixedly connected to the frame 1. The two stabilizing guide rails 55 are located on both sides of the displacement block 53 and below the lower mold frame 21. The length direction of the stabilizing guide rail 55 is parallel to the length direction of the drive rod 49. The stabilizing guide rail 55 passes through the molding zone 14. Four support wheels 56 are rotatably connected to the lower surface of the lower mold frame 21. The four support wheels 56 are located at the four corners of the lower mold frame 21. Two support wheels 56 are rolledly connected to one stabilizing guide rail 55.

[0059] The drive mechanism 48 starts and drives the lower mold frame 21 to move the upper mold frame 20 toward the separation plate 51. The separation component 52 connected to the upper mold frame 20 abuts against the separation slope 54 of the separation plate 51 on the frame 1 and climbs along it, thereby overcoming the weight of the upper mold frame 20.
