Description

Technical Field

[0001] This utility model belongs to the field of motor vehicle license plate production technology, and in particular relates to a longitudinal 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] This utility model discloses a longitudinal parking device for motor vehicle license plates, comprising a mounting frame, a material-picking mechanism and a parking conveyor belt mechanism sequentially arranged along the front-rear direction on the mounting frame, and a positioning structure corresponding to the rear side of the parking conveyor belt mechanism. The conveying direction of the parking conveyor belt mechanism is arranged along the front-rear direction. The parking conveyor belt mechanism includes a front parking belt roller and a rear parking belt roller spaced apart along the front-rear direction, and a parking conveyor belt disposed between the front parking belt roller and the rear parking belt roller. The front parking belt roller and the rear parking belt roller are rotatably mounted on the mounting frame. The device also includes a parking conveying drive mechanism for driving the front parking belt roller or the rear parking belt roller to rotate. The material-picking mechanism includes a component parallel to the front parking belt roller. The assembly includes a material-retrieving shaft mounted on the front side of the front parking conveyor roller, a flipping drive mechanism for driving the material-retrieving shaft to rotate, and a material-retrieving plate. The rear side of the material-retrieving plate is fixed to the material-retrieving shaft, and the front side of the material-retrieving plate is located away from the parking conveyor belt mechanism. Two extension plates are provided on the front side of the material-retrieving plate away from the material-retrieving shaft, spaced apart along the axial direction of the material-retrieving shaft. The assembly also includes a material-retrieving conveyor belt mechanism respectively located between the two extension plates and the corresponding sides of the material-retrieving shaft, and a material-retrieving power mechanism for driving the material-retrieving conveyor belt mechanism to rotate. The material-retrieving plate has elongated through holes corresponding to the material-retrieving conveyor belt mechanism, and the upper belt body of the material-retrieving conveyor belt protrudes from the surface of the material-retrieving plate.

[0017] The mounting frame of the longitudinal parking device for motor vehicle license plates is fixed on the upper side of the license plate conveyor belt device. The conveying direction of the parking conveyor belt mechanism is set in the same direction as the conveying direction of the license plate conveyor belt device. A receiving conveyor belt device is provided on the side of the license plate conveyor belt device corresponding to each group of longitudinal parking devices for motor vehicle license plates. A license plate transfer mechanism for transferring semi-finished motor vehicle license plates is provided between the rear side of the parking conveyor belt mechanism and the receiving conveyor belt device.

[0018] During operation, the flipping drive mechanism drives the material-receiving plate downwards via the material-receiving shaft, causing the two extension plates at the front of the material-receiving plate to flip to the lower sides of the license plate conveyor belt of the license plate conveyor device, forming an inclined conveying channel. When the license plate conveyor belt device conveys the semi-finished vehicle license plate to the two extension plates, under the pushing action of the license plate conveyor belt and the guiding action of the two extension plates, the semi-finished vehicle license plate moves along the two extension plates towards the upper part of the material-receiving plate. At the same time, since there are material-receiving conveyor belt mechanisms and material-receiving power mechanisms for driving the rotation of the material-receiving conveyor belt mechanisms between the two extension plates and the corresponding sides of the material-receiving shaft, the rotation of the material-receiving conveyor belts of the two material-receiving conveyor belt mechanisms can drive the semi-finished vehicle license plate to move upwards along the inclined conveying channel, realizing the transfer of the license plate. The vehicle license plate semi-finished product is picked up by the conveyor belt device and transported to the parking conveyor belt mechanism. The parking conveyor belt mechanism then transports the picked-up semi-finished product backward and positions it with a positioning structure. A license plate transfer mechanism then transfers the picked-up semi-finished product to a receiving conveyor belt device located on the side of the license plate conveyor belt device. The receiving conveyor belt device then transports the picked-up semi-finished product to the endorsement machine. When picking up the semi-finished product is not required, a flipping drive mechanism drives the picking plate upward through the picking shaft, raising the two extension plates on the front side of the picking plate. This does not affect the rearward transport of the semi-finished product by the license plate conveyor belt device, improving transport efficiency and thus increasing the production efficiency of the semi-finished product. This utility model's longitudinal parking device for vehicle license plates solves the problem of low efficiency in transporting semi-finished product to the endorsement machine, thereby improving the production efficiency of semi-finished product.

[0029] like Figures 1 to 6 As shown, this utility model discloses a longitudinal parking device for motor vehicle license plates. In use, the longitudinal parking device for motor vehicle license plates is fixed to the upper side of the license plate conveyor belt device 80 and is used to pick up the semi-finished motor vehicle license plates conveyed by the license plate conveyor belt device 80. Generally, it is understood that the conveying direction of the license plate conveyor belt device 80 is from the front to the rear. The semi-finished motor vehicle license plates are laid flat on the license plate conveyor belt of the license plate conveyor belt device 80 along the conveying direction of the license plate conveyor belt device 80. That is, the length direction of the semi-finished motor vehicle license plates is set along the conveying direction of the license plate conveyor belt device 80. The longitudinal parking device for motor vehicle license plates includes a mounting frame, a material picking mechanism 20 and a parking conveyor belt mechanism 30 are arranged sequentially on the mounting frame in the front-rear direction, and a positioning structure 50 is arranged at the rear side of the parking conveyor belt mechanism 30. The conveying direction of the parking conveyor belt mechanism 30 is set in the front-rear direction.

[0030] The mooring conveyor belt mechanism 30 includes a front mooring belt roller 31 and a rear mooring belt roller 32 spaced apart in the front-to-back direction, and a mooring conveyor belt disposed between the front mooring belt roller 31 and the rear mooring belt roller 32. The front mooring belt roller 31 and the rear mooring belt roller 32 are rotatably mounted on the mounting frame, and the mechanism also includes a mooring conveyor drive mechanism 35 for driving the front mooring belt roller 31 or the rear mooring belt roller 32 to rotate.

[0031] The material handling mechanism 20 includes a material handling shaft 21, which is parallel to the front parking conveyor roller 31 and rotatably mounted on a mounting bracket at the front side of the front parking conveyor roller 31; a flipping drive mechanism 40 for driving the material handling shaft 21 to rotate; and a material handling plate 22. The rear side of the material handling plate 22 is fixed to the material handling shaft 21, and the front side of the material handling plate 22 is located away from the parking conveyor belt mechanism 30. A spacer is provided on the front side of the material handling plate 22 away from the material handling shaft 21 along the axial direction of the material handling shaft 21. The two extension plates 221 are spaced apart, and the extension plates 221 are also provided with a material picking conveyor belt mechanism 23 and a material picking power mechanism 24 for driving the material picking conveyor belt 234 of the material picking conveyor belt mechanism 23 to rotate. The material picking plate 22 is provided with an elongated through hole 222 corresponding to each material picking conveyor belt mechanism 23. The upper belt body of the material picking conveyor belt 234 of the material picking conveyor belt mechanism 23 protrudes from the plate surface of the material picking plate 22.

[0032] For ease of understanding, combined with Figure 6 The following instructions are provided regarding the installation and use of the longitudinal parking device for motor vehicle license plates:

[0033] The mounting frame of the longitudinal parking device for motor vehicle license plates is fixed on the upper side of the license plate conveyor belt device 80. The conveying direction of the parking conveyor belt mechanism 30 is the same as that of the license plate conveyor belt device 80. A receiving conveyor belt device is provided on the side of the license plate conveyor belt device 80 for each group of longitudinal parking devices for motor vehicle license plates. A license plate transfer mechanism for transferring semi-finished motor vehicle license plates is provided between the rear side of the parking conveyor belt mechanism 30 and the receiving conveyor belt device.

[0034] During operation, the flipping drive mechanism 40 drives the picking plate 22 downwards via the picking shaft 21, causing the two extension plates 221 at the front of the picking plate 22 to flip to the lower part of both sides of the license plate conveyor belt of the license plate conveyor belt device 80, forming an inclined conveying channel. When the license plate conveyor belt device 80 conveys the semi-finished vehicle license plate to the two extension plates 221, under the pushing action of the license plate conveyor belt of the license plate conveyor belt device 80 and the guiding action of the two extension plates 221, the semi-finished vehicle license plate moves along the two extension plates 221 towards the upper side of the picking plate 22. At the same time, since there are picking conveyor belt mechanisms 23 and picking power mechanisms 24 for driving the picking conveyor belt 234 of the picking conveyor belt mechanism 23 to rotate between the two extension plates 221 and the corresponding sides of the picking shaft 21, the rotation of the picking conveyor belt 234 of the two picking conveyor belt mechanisms 23 can drive the semi-finished vehicle license plate to be conveyed along the inclined channel. The channel moves upward to pick up the semi-finished vehicle license plates conveyed by the license plate conveyor belt device 80, and then transports the picked-up semi-finished vehicle license plates to the parking conveyor belt mechanism 30. The parking conveyor belt mechanism 30 then transports the picked-up semi-finished vehicle license plates backward and is blocked and positioned by the positioning structure 50. The license plate transfer mechanism then transfers the picked-up semi-finished vehicle license plates to the receiving conveyor belt device located on the side of the license plate conveyor belt device 80. The receiving conveyor belt device then transports the picked-up semi-finished vehicle license plates to the endorsement machine. When it is not necessary to pick up the semi-finished vehicle license plates, the flipping drive mechanism 40 drives the picking plate 22 to flip upward through the picking shaft 21, so that the two extension plates 221 at the front side of the picking plate 22 are lifted upward. This does not affect the rearward transport of the semi-finished vehicle license plates by the license plate conveyor belt device 80, which can improve the conveying efficiency and thus improve the production efficiency of the semi-finished vehicle license plates.

[0035] During operation, since the mounting frame of the longitudinal parking device for motor vehicle license plates is fixed to the upper side of the license plate conveyor belt device 80, the material pick-up plate 22 can be flipped downward to form an inclined conveying channel to pick up the semi-finished motor vehicle license plates on the license plate conveyor belt device 80. When it is not necessary to pick up the semi-finished motor vehicle license plates, the material pick-up plate 22 can be flipped upward without affecting the rearward conveying of the semi-finished motor vehicle license plates by the license plate conveyor belt device 80, thereby improving the conveying efficiency. The longitudinal parking device for motor vehicle license plates of this utility model solves the problem of low efficiency in conveying semi-finished motor vehicle license plates to the endorsement machine and can improve the production efficiency of semi-finished motor vehicle license plates.

[0036] In this utility model, the license plate conveyor belt device 80 includes a base frame 81, a first conveyor belt mechanism 82, a middle conveyor belt mechanism 84, and a second conveyor belt mechanism 83 spaced apart on the base frame 81, and a conveying power mechanism that drives the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83 to rotate synchronously. The length direction of the semi-finished vehicle license plate is arranged along the front-rear direction and is placed flat on the middle conveyor belt mechanism 84. Two extension plates 221 are respectively arranged on both sides of the middle conveyor belt mechanism 84, so that the two extension plates 221 can be flipped to the lower part of the middle conveyor belt mechanism 84.

[0037] Specifically, the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83 each include a support rod fixed to the base frame 81, 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 rotatably mounted on the lower side of the support rod of the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83, and a rotation drive mechanism for driving the drive roller to rotate. Normally, the rotation drive mechanism is a motor.

The belts of the license plate conveyor belts of the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83 located on the lower side of the support rod are respectively wound around the front tension roller, the drive roller, and the rear tension roller.

[0038] The drive roller 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 correspond to the number plate conveyor belts of the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83, respectively. 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 and the rear tension roller are configured as roller structures, with the roller shaft fixedly mounted on the lower side of the support rod. Alternatively, the front and rear tension rollers 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.

[0039] Since the license plate conveyor belts of the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83 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, and the rear tension roller. Correspondingly, annular protrusions are provided on the inner ring side of the license plate conveyor belt, which achieves guidance and limiting through snap-fit.

[0040] Typically, an input-side support roller is provided on the lower side of the front end of the support rod near the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83, and an output-side support roller is provided on the lower side of the rear end of the support rod near the first conveyor belt mechanism 82, the middle conveyor belt mechanism 84, and the second conveyor belt mechanism 83. The input-side support roller and the output-side support roller are configured as roller structures or solid roller structures.

[0041] In some other embodiments, the license plate conveyor belt device 80 may also be configured as follows: including a base frame 81, a license plate conveyor belt mechanism fixed to the base frame 81, and two extension plates 221 respectively provided on both sides of the license plate conveyor belt mechanism.

[0042] In this utility model, the material picking conveyor belt mechanism 23 includes a first roller 231 rotatably mounted on the lower side of the front end of the elongated through hole 222, a second roller 232 rotatably mounted on the lower side of the rear end of the elongated through hole 222, and a third roller 233 disposed on the lower side of the rear end of the picking plate 22. The third roller 233 is fixed to the output shaft of the material picking power mechanism 24. A material picking conveyor belt 234 is wound between the first roller 231, the second roller 232, and the third roller 233. The material picking conveyor belt located between the first roller 231 and the second roller 232 protrudes from the surface of the picking plate 22.

[0043] Specifically, the material handling power mechanism 24 is fixed to the material handling shaft 21. Typically, the material handling power mechanism 24 is a motor.

[0044] For ease of installation, an upper mounting plane 211 is provided on the upper side of the material picking shaft 21, and a lower mounting plane 212 is provided on the lower side of the material picking shaft 21. The rear part of the material picking plate 22 is fixed to the upper mounting plane 211, and the material picking power mechanism 24 is fixed to the lower mounting plane 212.

[0045] like Figure 1As shown, to facilitate the flipping of the material-retrieving plate 22, the flipping drive mechanism 40 includes a push-pull drive mechanism 41 fixed to the mounting bracket, a connecting block 42 fixed to the output part of the push-pull drive mechanism 41, a roller 43 rotatably mounted on the side of the connecting block 42 away from the push-pull drive mechanism 41, and a swing arm 44 fixed to the end of the material-retrieving shaft 21. The swing arm 44 has an elongated groove arranged radially along the material-retrieving shaft 21, and the roller 43 is disposed inside the elongated groove. Typically, the push-pull drive mechanism 41 is a cylinder; however, it can also be an electric push rod. In some other embodiments, the flipping drive mechanism 40 can also be a motor, with the motor's output shaft connected to the material-retrieving shaft 21.

[0046] In this utility model, to facilitate the smooth transport of the semi-finished vehicle license plate picked up by the material picking mechanism 20 to the parking conveyor belt mechanism 30, an auxiliary support plate 223 is provided on the rear side of the material picking plate 22, and an obtuse angle α is provided between the auxiliary support plate 223 and the material picking plate 22, such as... Figure 4 As shown, after the material taking plate 22 flips downward, the upper side of the auxiliary pallet 223 is flush with the upper side of the parking conveyor belt. Usually, since the semi-finished vehicle license plate has a certain length, it is necessary to appropriately increase the size of the obtuse angle α to facilitate the movement of the semi-finished vehicle license plate from the material taking plate 22 to the parking conveyor belt mechanism 30. Commonly used angles are 120 degrees, 135 degrees, 160 degrees, etc.

[0047] Specifically, the auxiliary pallet 223, the material picking plate 22, and the two extension plates 221 are connected as an integrated structure.

[0048] In this utility model, the mooring conveyor belt includes a first mooring conveyor belt 33 and a second mooring conveyor belt 34, which are axially spaced along the front mooring belt roller 31 and the rear mooring belt roller 32.

[0049] To prevent the first and second parking conveyor belts 33 and 34 from skewing during rotation, a first annular groove and a second annular groove are respectively provided on the front parking roller 31 and the rear parking roller 32 at positions corresponding to the first and second parking conveyor belts 33 and 34, respectively. Typically, the front parking roller 31 and the rear parking roller 32 each include a main shaft portion and rotating shaft portions fixed to both ends of the main shaft portion. The two rotating shaft portions are coaxially arranged with the main shaft portion and are rotated during installation via bearing seats and bearings.

[0050] Furthermore, the parking conveyor belt mechanism 30 also includes a conveyor belt support plate 36 disposed between the front parking belt roller 31 and the rear parking belt roller 32 and fixed to the mounting frame, a front support shaft 37 disposed between the conveyor belt support plate 36 and the front parking belt roller 31, and a rear support shaft 38 disposed between the conveyor belt support plate 36 and the rear parking belt roller 32. The front support shaft 37 and the rear support shaft 38 are rotatably mounted on the mounting frame.
