Description

Technical Field

[0001] The present application relates to the field of license plate storage and retrieval technology, and in particular to a license plate retrieval device. Background Art

[0002] At present, there are many mechanisms on the market for grabbing motor vehicle license plates. During the process of grabbing license plates, multiple license plates may be grabbed at one time due to the mutual adhesion between license plates. The existing mechanisms have different ways of dealing with the adhesion between license plates. For example, spacers or partitions are placed between two adjacent license plates to avoid adhesion between adjacent license plates. Although this can achieve the purpose of grabbing one license plate at a time to a certain extent, it requires staff to place spacers or partitions between license plates multiple times, which increases the inconvenience of placing and taking license plates and affects the overall efficiency of the equipment. In addition, the spacers or partitions take up a lot of space in the card box, resulting in a large size and small capacity of the card box, affecting the overall volume of the equipment.

[0003] Therefore, in response to the above technical problems, how to provide a license plate retrieval device that has high efficiency in retrieval and placement of license plates and can retrieve single license plates without placing separation paper / partitions is a technical problem that technical personnel in this field need to solve. Utility Model Content

[0004] The purpose of this application is to provide a license plate retrieval device that optimizes the volume of the card storage mechanism. No paper or partition is required between the license plates, which greatly improves the speed of retrieving and placing the plates, can greatly reduce the number of times the staff needs to place the plates, and speeds up the overall working efficiency of the equipment.

[0005] To achieve the above objectives, the present application provides a license plate retrieval device, comprising:

[0006] The card storage mechanism includes a conveyor belt for placing a plurality of license plates, wherein the conveyor belt transports the frontmost license plate to a preset position, and adjacent license plates are placed in a close relationship in the thickness direction;

[0008] The card separating mechanism includes a card separating piece arranged at the outer edge of the preset path. When the license plate being grabbed is at a preset position or a preset section in the preset path, the distance between the card separating piece and the license plate being grabbed in the thickness direction is less than or equal to the thickness of the license plate, so that the card separating piece and the license plate adhered to the grabbed license plate interfere with or rub against each other, and the friction force generated by the friction is greater than the adhesion force of the adjacent license plates.

[0009] Preferably, it further comprises a base, the card depositing mechanism and the card retrieving mechanism are arranged on the base, and the card retrieving mechanism is arranged on the side of the license plate close to the front end.

[0010] Preferably, the card deposit mechanism further comprises:

[0011] a main frame, the conveyor belt being arranged on the main frame;

[0013] Side baffles are provided on the main frame, and the side baffles are located on both sides of the conveyor belt to limit the movement of the license plate on the conveyor belt;

[0014] A limit plate is fixedly arranged between the two side baffles and located on the upper side of the conveyor belt. The limit plate is used to limit the frontmost license plate to the preset position.

[0015] Preferably, the card separating mechanism further comprises a fixed frame arranged on the upper side of the side baffle, and the card separating member is arranged on the fixed frame.

[0016] Preferably, the card storage mechanism further comprises a detection sensor, and the detection sensor is used to detect whether the frontmost number plate reaches the preset position.

[0017] Preferably, the card taking mechanism further comprises:

[0018] Mounting plate;

[0022] Preferably, the gripping member comprises a manipulator, and the manipulator grips the license plate via a pneumatic suction cup.

[0023] Preferably, the device further comprises a detection mechanism disposed on the upper side of the card taking mechanism, wherein the detection mechanism comprises:

[0024] a conveyor belt for receiving the license plate grabbed by the grabbing member;

When the grabbed license plate moves along the preset path, since the distance between the license plate separating member and the grabbed license plate in the thickness direction of the grabbed license plate is less than or equal to the thickness of the license plate, if the grabbed license plate is adhered to other license plates, the adhered license plate and the license plate separating member will interfere or rub against each other. If interference occurs, the grabbing member will have a blocking effect on the adhered license plate, thereby separating the adhered license plate from the grabbed license plate, ensuring that the license plate taken out by the license plate retrieval mechanism is one piece; if friction occurs, the friction force generated by the friction is greater than the adhesion force of the adjacent license plates, thereby also making the grabbed license plate and the adhered license plate completely separated, thereby ensuring that the license plate taken out by the license plate retrieval mechanism is one piece.

[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper," "lower," "front," and "back" are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0046] like Figure 1As shown, in this embodiment, a license plate retrieval device is provided, which includes a card storage mechanism 1, a card retrieval mechanism 2, and a card separation mechanism 3. The card storage mechanism 1 is used to place multiple license plates 6, specifically, multiple license plates 6 are placed on a conveyor belt 11, and the conveyor belt 11 can transport the front-most license plate 6 to a preset position. When multiple license plates 6 are placed on the card storage mechanism 1, adjacent license plates 6 are placed in a close proximity in the thickness direction, and after the front-most license plate 6 is grabbed, the following license plates 6 will be moved laterally by the distance of one license plate 6 under the drive of the conveyor belt 11, ensuring that when the license plate retrieval mechanism 2 retrieves the license plates 6, the license plates 6 to be retrieved are all in the preset position, and the preset position is fixed.

[0047] The card retrieval mechanism 2 includes a grabbing member 24 for grabbing the frontmost license plate 6. The grabbing member 24 can be set in various ways, including but not limited to the setting of a manipulator, to ensure that the grabbing member 24 can grab the license plate 6 and separate it from the card storage mechanism 1 along a preset path.

[0048] The card separating mechanism 3 includes a card separating piece 32 arranged at the outer edge of a preset path. The preset path is the preset movement path of the above-mentioned grabbed number plate 6. When the grabbed number plate 6 is at a preset position or a preset section in the preset path, the distance between the card separating piece 32 and the grabbed number plate 6 in the thickness direction is less than or equal to the thickness of the number plate 6, so that the card separating piece 32 and the number plate 6 adhered to the grabbed number plate 6 interfere with or rub against each other. The friction force generated by the friction is greater than the adhesion force of the adjacent number plates 6. Therefore, under the action of the card separating piece 32, the front and rear number plates 6 are completely separated, ensuring that the number plate 6 taken out by the card taking mechanism 2 is always one.

[0049] In summary of the above embodiments, the present application places the number plate 6 on the conveyor belt 11 of the card storage mechanism 1, and the conveyor belt 11 conveys the number plate 6 to a preset position. When the card taking mechanism 2 takes the card, it will separate the front number plate 6 from the card storage mechanism 1 along the preset path. When the grabbed number plate 6 moves along the preset path, since the distance between the card separation member 32 and the grabbed number plate 6 in the thickness direction is less than or equal to the thickness of the number plate 6, if the grabbed number plate 6 is adhered to other number plates 6, This will cause the adhered number plate 6 to interfere with or rub against the card separating member 32. If interference occurs, the grabbing member 24 will have a blocking effect on the adhered number plate 6, thereby separating the adhered number plate 6 from the grabbed number plate 6, ensuring that the number plate 6 taken out by the card taking mechanism 2 is one piece; if friction occurs, the friction force generated by the friction is greater than the adhesion force of the adjacent number plates 6, thereby also completely separating the grabbed number plate 6 from the adhered number plate 6, thereby ensuring that the number plate 6 taken out by the card taking mechanism 2 is one piece.

[0050] Please refer to Figure 1 and Figure 2The license plate retrieval device of the present application also includes a base 5, which serves as the main supporting component of the device. The card storage mechanism 1 and the card retrieval mechanism 2 are both arranged on the base 5, and the card retrieval mechanism 2 is arranged on the side close to the frontmost license plate 6, so that the card retrieval mechanism 2 can grab the frontmost license plate 6.

[0051] Please refer to Figure 3 The card storage mechanism 1 also includes a main frame 12, a transmission motor 13, a side baffle 16 and a limit plate 14. The main frame 12 is arranged on the base 5. The main frame 12 can be an aluminum profile frame. The conveyor belt 11 is arranged on the main frame 12. The transmission motor 13 serves as the power source of the conveyor belt 11 and is also arranged on the main frame 12. The power end of the transmission motor 13 is connected to the conveyor belt 11 through a synchronous belt to drive the conveyor belt 11 to transport the number plate 6.

[0052] The side baffles 16 are provided on the main frame 12 and are located on both sides of the conveyor belt 11 . The side baffles 16 can limit or guide the movement of the license plate 6 along the conveying direction of the conveyor belt 11 , thereby ensuring the movement stability of the license plate 6 .

[0053] A limit plate 14 is provided at the front end of the conveyor belt 11. The limit plate 14 is fixedly arranged between the two side baffles 16 and is located above the conveyor belt 11. When the license plate 6 is transported to the limit plate 14 via the conveyor belt 11, the limit plate 14 can limit the frontmost license plate 6 to this position, and the limited position is the preset position of the frontmost license plate 6.

[0054] In addition, the card storage mechanism 1 also includes a detection sensor 15. When the frontmost license plate 6 reaches the limit position of the limit plate 14, that is, the preset position, the detection sensor 15 can be used to detect whether the frontmost license plate 6 has accurately reached the preset position, or to detect whether there is a license plate 6 at the preset position, thereby providing a pre-judgment condition for the subsequent grabbing mechanism.

[0055] Please refer to Figure 5 The card-splitting mechanism 3 also includes a fixed frame 31 arranged on the upper side of the side baffle 16, and a card-splitting member 32 is arranged on the fixed frame 31; specifically, the card-splitting member 32 can be a card-splitting plate or a card-splitting ring, that is, it can be plate-shaped or ring-shaped. No more restrictions are made here, as long as it can ensure that it can interfere with or rub against the adhered number plate 6, and all fall within the scope of protection of this application.

[0056] Please refer to Figure 4The card retrieval mechanism 2 also includes a mounting plate 21, a drive motor 22, and a rotating shaft 23. The mounting plate 21 can be mounted on the base 5 via a frame, providing a stable load-bearing effect for the card retrieval mechanism 2. The drive motor 22 is mounted on the mounting plate 21, and the power end of the drive motor 22 is provided with a driving tooth. The rotating shaft 23 is rotatably mounted on the two mounting plates 21, and the rotating shaft 23 is provided with a driven tooth that meshes with the driving tooth, thereby driving the rotating shaft 23 to rotate. On this basis, the grabbing member 24 is fixedly mounted on the rotating shaft 23, thereby driving the grabbing member 24 to rotate about the axis of the rotating shaft 23, thereby driving the grabbed number plate 6 to rotate along the axis of the rotating shaft 23.

[0057] It should be pointed out that the above-mentioned grasping member 24 of the present application can be a robot, which grasps the license plate 6 through a pneumatic suction cup; that is, the robot can achieve correspondence with the position of the front end license plate 6 through the rotation of the rotating shaft 23, thereby grasping the front end license plate 6, and after grasping, the license plate 6 rotates along the axis of the rotating shaft 23, that is, the path generated by the rotational movement is the preset path of the license plate 6.

[0058] In addition, the device of the present application further comprises a detection mechanism 4 disposed on the upper side of the card taking mechanism 2, and the detection mechanism 4 can be connected to the base 5 or the card taking mechanism 2 through a frame. Figure 6 The detection mechanism 4 includes a conveyor belt 41, a limit baffle 43 and a conveying motor 42. The conveyor belt 41 can be used to receive the license plate 6 grasped by the grasping member 24. That is to say, when the grasping member 24 rotates along the rotating shaft 23, the grasped license plate 6 will rotate to the position of the detection mechanism 4, thereby turning off the grasping function of the grasping member 24 and causing the license plate 6 to fall onto the conveyor belt 41.

[0059] Limit baffles 43 are provided on both sides of the conveyor belt 41. When the license plate 6 moves on the conveyor belt 41, the two limit baffles 43 can restrict or guide the direction of the license plate 6, so that the license plate 6 is conveyed along the conveyor belt 41 in a predetermined manner, ensuring the conveying stability of the license plate 6. The conveying motor 42 can be fixedly mounted on the frame. The power end of the conveying motor 42 is connected to the conveyor belt 41 via a synchronous belt to drive the conveyor belt 41 to move, thereby driving the license plate 6 to move on the conveyor belt 41.

[0060] In addition, please refer to Figure 6 The detection mechanism 4 also includes a distance measuring sensor 44 provided on the limit baffle 43. The distance measuring sensor 44 is used to detect the thickness of the license plates 6 on the conveyor belt 41 to determine whether there are multiple license plates 6; that is, when the actual thickness detected by the distance measuring sensor 44 is greater than the thickness of a single license plate 6, it indicates that multiple license plates 6 are stuck together.

[0061] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0062] This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the method and core ideas of this application. It should be noted that for those skilled in the art, without departing from the principles of this application, various improvements and modifications can be made to this application, and such improvements and modifications also fall within the scope of protection of the claims of this application.
