Description

Technical Field

[0001] This utility model relates to the field of license plate hot stamping equipment, and in particular to an automatic loading and unloading device for a license plate hot stamping machine. Background Technology

[0002] In the field of license plate production, automatic loading and unloading devices are core components connecting the hot stamping machine with the preceding and following processes. The precise transport of license plates to the hot stamping area and the efficient removal of finished license plates after hot stamping both rely on stable and reliable loading and unloading mechanisms. Existing technologies already include solutions for automating the entire license plate production process. For example, Chinese utility model patent CN219193748U discloses an automatic license plate production device. This device sequentially connects and installs an incoming material conveyor line, a shaping machine, an inspection and rejection unit, a labeling machine, a labeling machine, a pressing machine, an automatic license plate pressing machine, a hot stamping machine, and a license plate inspection machine. However, the core focus of the loading and unloading mechanism in the aforementioned prior art is to ensure the continuity of loading and unloading throughout the entire production line. Its structural layout needs to be adapted to the end of the conveyor belt of the entire production line, which results in a large overall volume of the loading and unloading mechanism and a significant increase in the floor space. In scenarios where production space is limited, the equipment layout is easily restricted. At the same time, for small and medium-sized production or for the need to upgrade the automation of only a single hot stamping process, this type of loading and unloading mechanism that relies on the complete production line has the problem of low space utilization. Utility Model Content

[0003] The purpose of this invention is to provide an automatic loading and unloading device for a license plate hot stamping machine. This invention achieves side-to-side loading and unloading of license plates through a combination of a rodless cylinder and a lifting cylinder, ensuring efficient loading and unloading while effectively reducing the overall size of the device.

[0004] The technical solution of this utility model is an automatic loading and unloading device for a license plate hot stamping machine, comprising mechanism fixing frames on both sides of a license plate conveying mechanism on a workbench. The device is characterized in that: the mechanism fixing frames on both sides are respectively provided with a loading component for feeding the license plate to the infeed end of the license plate conveying mechanism and a unloading component for removing the license plate from the discharge end of the license plate conveying mechanism. The loading and unloading components have the same structure and both include a rodless cylinder mounted on the mechanism fixing frame. The translation end of the rodless cylinder is provided with a lifting cylinder, and the lifting end of the lifting cylinder is provided with a suction cup assembly for adsorbing the license plate.

[0005] In the aforementioned automatic loading and unloading device for a license plate hot stamping machine, the mechanism fixing frame includes a trapezoidal body with a bottom folded edge on the bottom side, which is connected to the side of the license plate conveying mechanism by multiple bolts; the upper end of the trapezoidal body has a top folded edge that connects to the rodless cylinder.

[0006] In the aforementioned automatic loading and unloading device for a license plate hot stamping machine, the trapezoidal body has a plurality of through holes evenly distributed on it.

[0007] In the aforementioned automatic loading and unloading device for a license plate hot stamping machine, the translation end of the rodless cylinder has a flat plate, one end of the flat plate has a longitudinal plate, and the lifting cylinder is disposed on the longitudinal plate.

[0008] In the aforementioned automatic loading and unloading device for a license plate hot stamping machine, the suction cup assembly includes an intermediate block connected to the lifting end of a lifting cylinder. A suction cup fixing plate is connected to the bottom of the intermediate block, and a suction cup rod is connected to the suction cup fixing plate via bolts. The end of the suction cup rod has a suction cup head.

[0009] In the aforementioned automatic loading and unloading device for a license plate hot stamping machine, the suction cup fixing plate has adjusting grooves on both sides for adjusting the spacing of the suction cup rods, and the bolts on the suction cup rods are inserted into the adjusting grooves.

[0010] In the aforementioned automatic loading and unloading device for a license plate hot stamping machine, the suction cup rod has a long through groove, and the suction cup head is disposed in the long through groove.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses a combination of rodless cylinder and lifting cylinder to achieve side loading and unloading. The rodless cylinder enables precise lateral translation of the license plate along the conveying mechanism, while the lifting cylinder completes the vertical lifting and unloading of the license plate, ensuring accurate transfer of the license plate. This effectively reduces the size of the device, meeting the compact layout requirements of small and medium-sized production scenarios and adapting to the automation upgrade of a single hot stamping process. It effectively solves the problem of limited equipment layout when production space is limited.

[0012] 2. The adjustable horizontal grooves on both sides of the suction cup fixing plate can slide to adjust the lateral spacing of the suction cup rods as needed, and the spacing between the suction cup heads is effectively adjusted. The long through groove on the suction cup rod can adjust the position of the suction cup head in the length direction of the license plate. The dual adjustment structure can adapt to different specifications of license plates. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example: An automatic loading and unloading device for a license plate hot stamping machine, including mechanism fixing frames 2 disposed on both sides of the license plate conveying mechanism 1 on the worktable, as shown in the attached figure. Figure 1 As shown, the mechanism fixing frame 2 includes a trapezoidal body 8, with a bottom flange 9 on the bottom side of the trapezoidal body 8. The bottom flange 9 is connected to the side of the license plate conveying mechanism 1 by multiple bolts. The upper end of the trapezoidal body 8 has a top flange 10 connected to the rodless cylinder 5. The mechanism fixing frame adopts a trapezoidal body design, and the trapezoidal structure has both excellent load-bearing capacity and deformation resistance. The bottom flange is firmly connected to the side of the license plate conveying mechanism by multiple sets of bolts, and the top flange provides a horizontal installation reference for the rodless cylinder, ensuring stable cylinder translation and lifting movements during loading and unloading, and preventing license plate conveying deviation. The trapezoidal body 8 has multiple through holes 11 evenly distributed on it. By opening through holes, the strength can be maintained. While reducing the overall weight, the device achieves overall weight reduction. The two side mechanism mounting frames 2 are respectively equipped with a feeding assembly 3 for delivering license plates to the inlet end of the license plate conveying mechanism 1 and a discharging assembly 4 for removing license plates from the outlet end of the license plate conveying mechanism 1. The feeding assembly 3 and discharging assembly 4 have identical structures, both including a rodless cylinder 5 mounted on the mechanism mounting frame 2. The translation end of the rodless cylinder 5 is equipped with a lifting cylinder 6. The rodless cylinder enables precise lateral translation of the license plate along the conveying mechanism, while the lifting cylinder performs vertical lifting and placement of the license plate. The lifting end of the lifting cylinder 6 is equipped with a suction cup assembly 7 for adsorbing the license plate. A license plate placement platform 20 is provided on the side of the inlet end of the license plate conveying mechanism, as shown in the attached figure. Figure 2 As shown, the license plate to be hot-stamped is placed on the plate placement table. A finished product placement table 21 is provided at the discharge end of the license plate conveying mechanism, where the hot-stamped license plate is placed. In use, this utility model mainly involves setting a hot-stamping roller 22, a hot-stamping film feeding roller 23, and a hot-stamping film receiving roller 24 between the feeding and unloading components. The prepared hot-stamping film passes through the bottom of the hot-stamping roller. The rodless cylinder 5 has a flat plate 12 on its translation end, and a longitudinal plate 13 at one end of the flat plate 12. A lifting cylinder 6 is mounted on the longitudinal plate 13, as shown in the attached diagram. Figure 3 As shown, the suction cup assembly 7 includes an intermediate block 14 connected to the lifting end of the lifting cylinder 6. A suction cup fixing plate 15 is connected to the bottom of the intermediate block 14. The intermediate block is connected to the suction cup fixing plate by screws. A suction cup rod 16 is connected to the suction cup fixing plate 15 by bolts. The end of the suction cup rod 16 has a suction cup head 17. There are four pairs of suction cup rods, each with a suction cup head at its end, corresponding to the four corners of the license plate. The suction cup fixing plate 15 has adjusting grooves 18 on both sides for adjusting the spacing of the suction cup rods 16, as shown in the attached figure. Figure 4 As shown, the bolts on the suction cup rod 16 pass through the adjusting transverse groove 18. The suction cup rod 16 has a long through groove 19, and the suction cup head 17 is disposed in the long through groove 19. The upper end of the suction cup head has a nut. Tightening the nut tightly fits the nut against the suction cup rod, thereby fixing the suction cup head. The adjusting transverse grooves on both sides of the suction cup fixing plate can slide to adjust the lateral spacing of the suction cup rod as needed, and the spacing between the suction cup heads is effectively adjusted. This structure can adapt to license plates of different widths. The long through groove on the suction cup rod can adjust the position of the suction cup head in the length direction of the license plate. This structure can adapt to license plates of different lengths. The dual adjustment structure can adapt to different specifications of license plates. This utility model also has the following advantages: It integrates two sets of robotic arms in the feeding and discharging directions of the hot stamping equipment at a 90-degree angle, which overturns the 180-degree (0-degree) feeding and discharging method on the market, greatly reducing the space occupied by the overall hot stamping process. At the same time, it is convenient for the operator to monitor the operation of the entire equipment. If a set of suction cups is added to the robotic arms, two license plates can be grabbed at the same time for double-plate hot stamping, and the hot stamping efficiency can be doubled.

[0017] The working principle of this utility model is as follows: The lifting cylinder of the feeding component extends, driving the suction cup component to descend vertically until the suction cup head is in contact with the surface of the license plate to be hot-stamped on the top layer of the plate placement platform; the suction cup component is connected to negative pressure, and the suction cup head generates suction force to firmly hold the license plate. After suction is completed, the lifting cylinder retracts, driving the adsorbed license plate vertically upward to the preset height. The rodless cylinder is activated, and its translation end drives the lifting cylinder, suction cup component, and adsorbed license plate to move laterally along the horizontal reference of the top folded edge of the mechanism fixing frame until the license plate is precisely positioned directly above the feeding end of the license plate conveying mechanism. The lifting cylinder extends again, placing the license plate smoothly on the conveying surface of the feeding end of the license plate conveying mechanism; the suction cup component cuts off the negative pressure, and the suction cup head releases the license plate; then the lifting cylinder retracts and resets, and the rodless cylinder drives the entire... The loading actuator moves horizontally back above the license plate placement platform, awaiting the next material handling cycle. During unloading, the lifting cylinder of the unloading component extends, causing the suction cup assembly to descend vertically, making the suction cup head adhere to the surface of the finished license plate at the output end of the license plate conveying mechanism. The suction cup assembly applies negative pressure to attract the finished license plate, and the lifting cylinder retracts, vertically lifting the finished license plate to a preset height. The rodless cylinder starts, driving the lifting cylinder, suction cup assembly, and finished license plate to move laterally along the top folded edge of the mechanism's fixing frame to directly above the finished product placement platform. The lifting cylinder extends, smoothly placing the finished license plate on the finished product placement platform. The suction cup assembly cuts off the negative pressure, releasing the finished product. Subsequently, the lifting cylinder retracts and resets, and the rodless cylinder drives the unloading actuator to move horizontally back above the output end of the license plate conveying mechanism, awaiting the next finished product collection cycle.
