Description

Technical Field

[0001] This utility model belongs to the field of motor vehicle license plate production technology, and in particular relates to a lateral parking device for motor vehicle license plates. Background Technology

[0002] During the production of vehicle license plates, a QR code needs to be affixed to the semi-finished vehicle license plate as an identification serial number. The affixing operation is completed by a signing machine using laser printing on the semi-finished vehicle license plate.

[0003] Currently, semi-finished vehicle license plates are transported by conveyor belts. To improve the efficiency of the endorsement process, multiple endorsement machines are installed on the side of the conveyor belt, with a robotic arm at each machine. A lifting plate is installed on the upper side of the conveyor belt at each machine, which is used to block the semi-finished vehicle license plates on the conveyor belt when the robotic arm grabs them. This structure is shown in the automatic endorsement system for vehicle license plates published in CN118419539A. The main drawback is that when grabbing a semi-finished vehicle license plate, the falling lifting plate will hinder the subsequent semi-finished vehicle license plates from being transported further on the conveyor belt, resulting in low conveying efficiency and seriously affecting the production efficiency of semi-finished vehicle license plates.

[0015] The beneficial effects achieved by adopting the above technical solution are as follows:

[0016] The lateral parking device for vehicle license plates of this utility model includes a mounting frame, a material picking mechanism, a parking conveyor belt mechanism, a material supporting mechanism, and a limiting structure arranged sequentially on the mounting frame, as well as a horizontal material feeding mechanism arranged at the corresponding material supporting mechanism; the material picking mechanism includes a material picking shaft rotatably mounted on the mounting frame, a flipping drive mechanism for driving the material picking shaft to rotate, and two rocker arms spaced apart along the axial direction of the material picking shaft, the first end of the rocker arm being located away from the parking conveyor belt mechanism, and the second end of the rocker arm being fixed to the material picking shaft, and also includes a first roller rotatably mounted on the first end of the rocker arm, a second roller rotatably mounted on the second end of the rocker arm, and a material picking conveyor belt arranged between the first roller and the second roller, the second roller being coaxially arranged with the material picking shaft; the lateral parking device for vehicle license plates also includes a material picking power mechanism for driving the parking conveyor belt of the parking conveyor belt mechanism and the material picking conveyor belt of the material picking mechanism to rotate.

[0017] The lateral parking device for vehicle license plates is fixed to the upper side of the license plate conveyor belt device. During operation, a tilting drive mechanism drives two rocker arms to tilt downwards, causing the first ends of the two rocker arms to tilt to the lower part of both sides of the license plate conveyor belt, forming an inclined conveying channel. When the license plate conveyor belt device conveys the semi-finished vehicle license plate to the first ends of the two rocker arms, under the pushing action of the license plate conveyor belt and the material-retrieving conveyor belts of the two rocker arms, the semi-finished vehicle license plate moves upward along the inclined conveying channel formed by the two rocker arms, thus picking up the semi-finished vehicle license plate conveyed by the license plate conveyor belt device. The material-retrieving conveyor belts of the two rocker arms then transport the picked-up semi-finished vehicle license plate to the parking conveyor belt of the parking conveyor belt mechanism. The semi-finished vehicle license plate is then transported by the parking conveyor belt mechanism to the material support mechanism and blocked and positioned by the limiting structure. The horizontal material feeding mechanism then moves the semi-finished vehicle license plate to the corresponding receiving conveyor belt device, which then transports it to the endorsement machine. When the semi-finished vehicle license plate is not needed, the flipping drive mechanism drives the two rocker arms to flip upwards, raising the first ends of the two rocker arms. This does not affect the rearward transport of the semi-finished vehicle license plate by the license plate conveyor belt device, improving transport efficiency and thus increasing the production efficiency of the semi-finished vehicle license plate. This solves the problem of low efficiency in transporting semi-finished vehicle license plates to the endorsement machine and improves the production efficiency of the semi-finished vehicle license plate.

[0018] The vehicle license plate lateral parking device is fixed to the upper side of the license plate conveyor belt device. During operation, the two rocker arms flip downward to form an inclined conveying channel, which picks up the semi-finished vehicle license plates from the license plate conveyor belt device. When it is not necessary to pick up the semi-finished vehicle license plates, the two rocker arms flip upward without affecting the rearward conveying of the semi-finished vehicle license plates by the license plate conveyor belt device. This improves the conveying efficiency and solves the problem of low efficiency in conveying semi-finished vehicle license plates to the endorsement machine, thereby improving the production efficiency of semi-finished vehicle license plates.

[0032] like Figures 1 to 7 As shown, the lateral parking device 100 for motor vehicle license plates includes a mounting frame, a material picking mechanism 120, a parking conveyor belt mechanism 130, a material supporting mechanism 140, a limiting structure 160, and a horizontal material pushing mechanism 150 provided at the corresponding material supporting mechanism 140.

[0033] The material handling mechanism 120 includes a material handling shaft 121 rotatably mounted on the mounting frame, a flipping drive mechanism for driving the material handling shaft 121 to rotate, and two rocker arms 122 spaced apart along the axial direction of the material handling shaft 121. The first end of the rocker arm 122 is located away from the mooring conveyor belt mechanism 130, and the second end of the rocker arm 122 is fixed to the material handling shaft 121. It also includes a first roller 123 rotatably mounted on the first end of the rocker arm 122, a second roller 124 rotatably mounted on the second end of the rocker arm 122, and a material handling conveyor belt 126 disposed between the first roller 123 and the second roller 124. The second roller 124 is coaxially arranged with the material handling shaft 121.

[0034] The parking conveyor belt mechanism 130 includes a front parking belt roller 131 and a rear parking belt roller 132 spaced apart in the front-to-back direction, and a parking conveyor belt disposed between the front parking belt roller 131 and the rear parking belt roller 132. The front parking belt roller 131 and the rear parking belt roller 132 are rotatably mounted on the mounting frame.

[0035] The lateral parking device 100 for motor vehicle license plates also includes a material handling power mechanism for driving the parking conveyor belt of the parking conveyor belt mechanism 130 and the material handling conveyor belt 126 of the material handling mechanism 120 to rotate.

[0036] For ease of understanding, combined with Figure 8 and Figure 9 The following instructions are provided regarding the installation and use of the lateral parking device 100 for motor vehicle license plates:

[0037] The intelligent parking and material handling equipment for motor vehicle license plates includes a license plate conveyor belt device 200 for conveying semi-finished motor vehicle license plates, at least two sets of the aforementioned lateral parking devices 100 for motor vehicle license plates are arranged at intervals on the upper side of the license plate conveyor belt device 200 along the conveying direction of the license plate conveyor belt device 200, the mounting frame of the lateral parking device 100 for motor vehicle license plates is fixed on the upper side of the license plate conveyor belt device 200, the conveying direction of the parking conveyor belt mechanism 130 is arranged in the same direction as the conveying direction of the license plate conveyor belt device 200, and a receiving conveyor belt device 300 is provided on the side of the license plate conveyor belt device 200 corresponding to each set of lateral parking devices 100 for motor vehicle license plates.

[0038] It is generally understood that the conveying direction of the license plate conveyor belt device 200 is from front to back, and the semi-finished vehicle license plate is laid flat on the license plate conveyor belt of the license plate conveyor belt device 200 in a direction perpendicular to the conveying direction of the license plate conveyor belt device 200.

[0039] During operation, the two rocker arms 122 are driven downwards by the flipping drive mechanism, causing the first ends of the two rocker arms 122 to flip to the lower part of both sides of the license plate conveyor belt of the license plate conveyor belt device 200, forming an inclined conveying channel. When the license plate conveyor belt device 200 conveys the semi-finished vehicle license plate to the first ends of the two rocker arms 122, under the pushing action of the license plate conveyor belt of the license plate conveyor belt device 200 and the material picking conveyor belt 126 of the two rocker arms 122, the semi-finished vehicle license plate moves upward along the inclined conveying channel formed by the two rocker arms 122, thereby picking up the semi-finished vehicle license plate conveyed by the license plate conveyor belt device 200, and the material picking conveyor belt 126 of the two rocker arms 122 transports the picked-up semi-finished vehicle license plate to the parking area. The parking conveyor belt of the parking conveyor belt mechanism 130 then transports the picked-up semi-finished vehicle license plate to the material support mechanism 140, where it is blocked and positioned by the limiting structure 160. The horizontal material feeding mechanism 150 then moves the picked-up semi-finished vehicle license plate to the receiving conveyor belt device 300 on the corresponding side, and the receiving conveyor belt device 300 transports the picked-up semi-finished vehicle license plate to the endorsement machine. When it is not necessary to pick up the semi-finished vehicle license plate, the flipping drive mechanism drives the two rocker arms 122 to flip upward, raising the first ends of the two rocker arms 122. This does not affect the rearward transport of the semi-finished vehicle license plate by the license plate conveyor belt device 200, thereby improving the conveying efficiency and thus improving the production efficiency of the semi-finished vehicle license plate.

[0040] During operation, the vehicle license plate lateral parking device 100 is fixed to the upper side of the license plate conveyor belt device 200. After the two rocker arms 122 are flipped downwards, they can form an inclined conveying channel to pick up the semi-finished vehicle license plates on the license plate conveyor belt device 200. When it is not necessary to pick up the semi-finished vehicle license plates, the two rocker arms 122 are flipped upwards, which will not affect the rearward conveying of the semi-finished vehicle license plates by the license plate conveyor belt device 200, thus improving the conveying efficiency. The vehicle license plate lateral parking device of this utility model solves the problem of low efficiency in conveying semi-finished vehicle license plates to the endorsement machine and can improve the production efficiency of semi-finished vehicle license plates.

[0041] In this utility model, the license plate conveyor belt device 200 includes a base frame 210, a first conveyor belt mechanism 220, a middle conveyor belt mechanism 240, and a second conveyor belt mechanism 230 spaced apart on the base frame 210, and a conveying power mechanism that drives the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230 to rotate synchronously. The semi-finished vehicle license plate is placed across the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230, enabling the semi-finished vehicle license plate to move smoothly; two rocker arms 1 The 22 are respectively positioned between the first conveyor belt mechanism 220 and the middle conveyor belt mechanism 240, and between the middle conveyor belt mechanism 240 and the second conveyor belt mechanism 230, so that the first roller 123 at the first end of the two rocker arms 122 can be flipped to the lower part of the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230, thus avoiding the problem of the semi-finished vehicle license plate moving from the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230 to the material picking mechanism 120, and preventing the problem of the semi-finished vehicle license plate from tilting and falling off.

[0042] Specifically, the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230 each include a support rod fixed to the base frame 210, a front roller and a rear roller rotatably mounted at both ends of the support rod, and a license plate conveyor belt arranged around the outer periphery of the front roller, the support rod, and the rear roller; it also includes a drive roller 250 rotatably mounted on the lower side of the support rod of the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230, and a rotation drive mechanism for driving the drive roller 250 to rotate. Typically, the rotation drive... The mechanism is a motor. Front tension roller 261 and rear tension roller 262 are rotatably installed on the front and rear sides of the drive roller 250, corresponding to the license plate conveyor belt of the first conveyor belt mechanism 220, the license plate conveyor belt of the middle conveyor belt mechanism 240, and the license plate conveyor belt of the second conveyor belt mechanism 230, respectively. The belts of the license plate conveyor belts of the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230 located on the lower side of the support rod are respectively wound around the front tension roller 261, the drive roller 250, and the rear tension roller 262.

[0043] The drive roller 250 includes a drive roller main shaft, and a first roller body, a middle roller body, and a second roller body, which are spaced apart from the drive roller main shaft and respectively correspond to the license plate conveyor belts of the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230. Typically, the drive roller main shaft, the first roller body, the middle roller body, and the second roller body are connected as a single solid roller structure. The front tension roller 261 and the rear tension roller 262 are configured as roller structures, with the roller shaft fixedly mounted on the lower side of the support rod. Alternatively, the front tension roller 261 and the rear tension roller 262 can also be configured as solid roller structures, in which case they would need to be rotatably mounted on the lower side of the support rod.

[0044] Since the license plate conveyor belts of the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230 are relatively long, in order to prevent the license plate conveyor belt from deviating, straight guide grooves are provided on the upper and lower sides of the support rods, and annular guide grooves are provided on the outer peripheral sides of the front roller, the rear roller, the first roller body, the middle roller body, the second roller body, the front tension roller 261, and the rear tension roller 262. Correspondingly, annular protrusions are provided on the inner ring side of the license plate conveyor belt, which achieves guidance and limitation through snap-fit.

[0045] Typically, an input-side support roller 270 is provided on the lower side of the front end of the support rod near the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230, and an output-side support roller 280 is provided on the lower side of the rear end of the support rod near the first conveyor belt mechanism 220, the middle conveyor belt mechanism 240, and the second conveyor belt mechanism 230. The input-side support roller 270 and the output-side support roller 280 are configured as roller structures or solid roller structures.

[0046] In this utility model, to facilitate the smooth transport of the semi-finished vehicle license plate picked up by the material handling mechanism 120 to the parking conveyor belt mechanism 130, the parking conveyor belt includes a first parking conveyor belt 133, a middle parking conveyor belt 135, and a second parking conveyor belt 134, which are axially spaced along the front parking belt roller 131 and the rear parking belt roller 132. Correspondingly, two rocker arms 122 are respectively disposed between the first parking conveyor belt 133 and the middle parking conveyor belt 135, and between the middle parking conveyor belt 135 and the second parking conveyor belt 134. The roller mounting shaft 1231 of the first roller 123 is slidably mounted on the rocker arm in the direction of approaching / moving away from the material handling shaft 121. 122, elastic tensioning mechanisms 125 are respectively provided between the two sides of the rocker arm 122 and the two ends of the roller mounting shaft 1231 of the first roller 123 for pushing the first roller 123 to slide away from the material taking shaft 121, so that the material taking conveyor belt 126 between the first roller 123 and the front parking belt roller 131 is in a tensioned state. A belt-supporting roller 127 rotatably mounted on the rocker arm 122 is also provided between the first roller 123 and the second roller 124. The material taking conveyor belt 126 extends to the front parking belt roller 131 and is fitted onto the front parking belt roller 131. The lower part of the material taking conveyor belt 126 passes over the upper side of the belt-supporting roller 127, such as... Figure 5 and Figure 6 As shown.

[0047] To prevent the first mooring conveyor belt 133, the middle mooring conveyor belt 135, and the second mooring conveyor belt 134 from skewing during rotation, a first annular groove, a middle annular groove, and a second annular groove are respectively provided on the front mooring belt roller 131 and the rear mooring belt roller 132 at positions corresponding to the first mooring conveyor belt 133, the middle mooring conveyor belt 135, and the second mooring conveyor belt 134. This can prevent the first mooring conveyor belt 133, the middle mooring conveyor belt 135, and the second mooring conveyor belt 134 from skewing. A material picking belt annular groove is provided on the front mooring belt roller 131 at the position corresponding to the material picking conveyor belt 126 of the rocker arm 122. This can prevent the material picking conveyor belt 126 from skewing. Typically, the front parking belt roller 131 and the rear parking belt roller 132 each include a parking belt roller main shaft and rotating shafts fixed at both ends of the parking belt roller main shaft. The two rotating shafts are coaxially arranged with the parking belt roller main shaft. During installation, rotation is achieved through bearing seats and bearings.

[0050] The belt roller 127 is configured as a drum structure, but it can also be configured as follows: including a belt roller mounting shaft and a belt cylinder body fitted onto and rotatably connected to the belt roller mounting shaft. Typically, the rotatable connection is achieved through bearings.

[0051] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the elastic tensioning mechanism 125 includes a mounting base 1251 fixed between the roller mounting shaft 1231 and the second end of the rocker arm 122 on the side of the rocker arm 122.

In order to facilitate the sliding of the first roller 123, both ends of the roller mounting shaft 1231 are set as square rods, which can prevent the rotation between the roller mounting shaft 1231 and the elongated through holes.

[0053] Since the end of the picking conveyor belt 126 near the front parking roller 131 is fitted onto the front parking roller 131, the parking conveyor belt and the picking conveyor belt 126 can rotate synchronously. To facilitate driving, a picking power mechanism is provided, which is connected to the front parking roller 131 or the rear parking roller 132. Typically, the picking power mechanism is a motor, with a motor synchronous pulley fixed on the output shaft of the motor, and a roller synchronous pulley fixed at the end of the corresponding side of the front parking roller 131 or the rear parking roller 132.

The limiting structure 160 is provided at the position corresponding to the rear material support roller 143. During material handling, the two rocker arms 122 flip downwards, and the semi-finished vehicle license plate moves upwards along the inclined conveyor channel formed by the two rocker arms 122 to the parking conveyor belt mechanism 130. When the first parking conveyor belt 133, the middle parking conveyor belt 135, and the second parking conveyor belt 134 of the parking conveyor belt mechanism 130 rotate, they can transport the semi-finished vehicle license plate to the material support mechanism 140.
