Description

Technical Field

[0001] This utility model relates to the field of gripping mechanism technology, specifically a gripping mechanism for producing vehicle license plates. Background Technology

[0002] Vehicle license plates, also known as vehicle plates, are legal marks issued by the national vehicle management authority after registering motor vehicles in accordance with the law. They are equivalent to a car's "ID card," used to uniquely identify a car and facilitate road traffic management, vehicle tracking, tax collection, and other functions.

[0003] During the stacking and feeding of semi-finished vehicle license plates, due to factors such as humid environment or long storage time, adjacent semi-finished products are prone to sticking together, requiring external force to forcibly separate them, which affects production efficiency. To solve this problem, non-woven fabric or release paper is usually inserted between each semi-finished product as a separating material when stacking.

[0004] However, before proceeding to the lettering process, the insulating material must be removed so that the semi-finished license plate can be picked up by an external robotic arm for further processing. Currently, the license plate gripping mechanism installed on the end effector of the robotic arm is only capable of gripping metal plates and cannot effectively pick up non-woven fabrics or release paper. Therefore, the robotic arm needs to perform additional manual or auxiliary separation operations when picking up materials, which complicates the overall gripping process and reduces the efficiency and continuity of automated operations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a gripping mechanism for vehicle license plate production, which can grip the license plate and the separator separately.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gripping mechanism for producing vehicle license plates, comprising a mounting bracket mounted on an external robotic arm end effector, a connecting plate fixedly connected to one side of one end of the mounting bracket, a first mounting plate connected to the lower end of the connecting plate, two second mounting plates fixedly connected to the other side of the mounting bracket near the connecting plate, mounting blocks connected to the other ends of the two second mounting plates, license plate gripping components connected to both ends of the first mounting plate and inside the two mounting blocks, a separator gripping component connected to the middle of the mounting bracket near the connecting plate, and a proximity sensor connected to the end of the mounting bracket near the second mounting plates.

[0007] Furthermore, each of the four license plate gripping components includes a height adjustment rod and a regular suction cup. The lower ends of the four height adjustment rods pass through both ends of the first mounting plate and the two mounting blocks, and are fixedly connected to the upper ends of the four regular suction cups. The interiors of the four height adjustment rods are hollow, and the hollow interiors of the four height adjustment rods are connected to the interiors of the four regular suction cups.

[0008] Furthermore, the four height adjustment rods are respectively fastened to both ends of the No. 1 mounting plate and two mounting blocks by several nuts.

[0009] Furthermore, both ends of the No. 1 mounting plate and the two mounting blocks are provided with adjustment ports for the horizontal adjustment of the height adjustment rod.

[0010] Furthermore, the isolation component gripping assembly includes a needle-type suction cup and a cylinder. The outer wall of the cylinder is fixedly connected to the upper surface of the mounting bracket near the first mounting plate. The output end of the cylinder is fixedly connected to the upper end of the needle-type suction cup. The needle surface of the needle-type suction cup faces downward and is located between four ordinary suction cups.

[0011] Furthermore, each of the two No. 2 mounting plates has a movable opening at the end away from the mounting bracket, and an anti-detachment opening is provided on the upper surface of each movable opening. An extension plate is fixedly connected to one side of the mounting block, and a guide strip is fixedly connected to the upper surface of the other end of the extension plate. The extension plate is slidably connected to the movable opening, and the guide strip is slidably connected to the anti-detachment opening.

[0012] Furthermore, both mounting plates No. 2 have several tightening knobs threaded inside, with the screw end of the tightening knob penetrating into the moving port and abutting against the side wall of the extension plate.

[0013] Furthermore, anti-detachment blocks are fixedly connected to both ends of the two extension plates, and the width of the anti-detachment blocks is greater than the width of the extension plates and the width of the moving opening.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This gripping mechanism for vehicle license plate production integrates a license plate gripping component and a separator gripping component. It can simultaneously grip and separate the semi-finished license plate and the separator without manual or auxiliary equipment intervention. It solves the limitation of traditional mechanisms that can only grip metal plates, reduces process interruptions, realizes full automation of the "grip-separation-transfer" process, and improves the continuity of the production line. 2. This type of gripping mechanism for vehicle license plate production has a height adjustment rod for the license plate gripping component that is fastened to the mounting plate by a nut. The height of the suction cup can be flexibly adjusted according to the thickness of the license plate. The first mounting plate and the mounting block have a horizontal adjustment port, which, together with the moving port and guide strip structure of the second mounting plate, allows the suction cup to slide and adjust the spacing in the horizontal direction. It is suitable for gripping different sizes (such as small car / large car license plates) and has strong versatility. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-3 A gripping mechanism for producing vehicle license plates includes a mounting bracket 1 mounted on an end effector of an external robotic arm. A connecting plate 3 is fixedly connected to one side of one end of the mounting bracket 1. A first mounting plate 2 is connected to the lower end of the connecting plate 3. Two second mounting plates 4 are fixedly connected to the other side of the mounting bracket 1 near the connecting plate 3. A mounting block 6 is connected to the other end of each of the two second mounting plates 4. License plate gripping components are connected to both ends of the first mounting plate 2 and inside the two mounting blocks 6. A spacer gripping component is connected to the middle of the mounting bracket 1 near the connecting plate 3. A proximity sensor 7 is connected to the end of the mounting bracket 1 near the second mounting plate 4.

[0019] like Figures 1 to 3 As shown, before using the gripping mechanism for vehicle license plate production in this utility model, the mounting bracket 1 is first installed and fixed on an external automated production line (hereinafter referred to as the production line). After debugging, it can be put into normal use. During use, as the license plate semi-finished product and the isolation component (such as non-woven fabric) from the upstream of the production line move to the license plate gripping component and the isolation component gripping component, the external robotic arm (hereinafter referred to as the robotic arm) controls the mounting bracket 1 and all the components on the mounting bracket 1 (hereinafter referred to as the entire mechanism) to approach the production line together. At this time, the proximity sensor 7 automatically detects whether the approaching component is the license plate or the isolation component. If it is a barrier component, the barrier component gripping component will automatically start at this time. The barrier component gripping component can automatically grab the barrier component that is close to it on the production line. After the barrier component is grabbed, the barrier component gripping component will lift the barrier component to above the four license plate gripping components, and then the license plate and barrier component on the production line can be directly separated. Then, an external air source (such as an air pump) will suck up the license plate through the four license plate gripping mechanisms. After that, the robotic arm will control the license plate and barrier component to move to their respective next process and then reset to grab and separate the next license plate and barrier component. The whole process does not require human intervention, which is more automated and more efficient.

[0020] As a preferred embodiment of this utility model, each of the four license plate gripping components includes a height adjustment rod 5 and a common suction cup 9. The lower ends of the four height adjustment rods 5 pass through both ends of the first mounting plate 2 and the two mounting blocks 6 respectively, and are fixedly connected to the upper ends of the four common suction cups 9 respectively. The interior of each of the four height adjustment rods 5 is hollow, and the hollow interior of each of the four height adjustment rods 5 is connected to the interior of each of the four common suction cups 9.

[0021] More specifically, when it is necessary to grab the license plate, simply turn on the external air source. At this time, the input end of the external air source starts to draw air from the hollow position of the four height adjustment rods 5, which can then pick up the license plate below the ordinary suction cup 9. After that, simply place the license plate to the next process with the robotic arm, and then turn off the external air source (or turn on the external air source in reverse). At this time, the license plate will fall automatically without human intervention.

[0022] As a preferred embodiment of this utility model, the four height adjustment rods 5 are respectively fastened to both ends of the first mounting plate 2 and the two mounting blocks 6 by a number of nuts.

[0023] More specifically, by setting a nut on the outside of the height adjustment rod 5, the height of the height adjustment rod 5 on the mounting plate 2 or mounting block 6 can be adjusted according to the thickness of different robotic arms or license plates, making it easier to grab the license plate.

[0024] As a preferred embodiment of this utility model, both ends of the first mounting plate 2 and the two mounting blocks 6 are provided with adjustment ports 16 for the horizontal adjustment of the height adjustment rod 5.

[0025] More specifically, by setting the adjustment port 16, the position of the height adjustment rod 5 can be adjusted within a certain range according to the width of different license plates, thereby improving the gripping stability.

[0026] As a preferred embodiment of this utility model, the isolation component gripping assembly includes a needle suction cup 8 and a cylinder 11. The outer wall of the cylinder 11 is fixedly connected to the upper surface of the mounting bracket 1 near the first mounting plate 2. The output end of the cylinder 11 is fixedly connected to the upper end of the needle suction cup 8. The needle surface of the needle suction cup 8 faces downward, and the needle suction cup 8 is located between four ordinary suction cups 9.

[0027] More specifically, when it is necessary to grab the isolation piece, simply activate the cylinder 11. The output end of the cylinder 11 extends downward and pushes the needle suction cup 8 down together. After the needle suction cup 8 descends, the needles on the bottom of the needle suction cup 8 will insert into the isolation piece. Then, as the cylinder 11 resets, the isolation piece can be separated from the top of the license plate. It should be noted that the needle suction cup 8 is a mature existing technology, which includes, but is not limited to, a needle assembly that is fixed by friction when inserted into the surface of a workpiece (usually supporting fixed or adjustable stroke to adapt to different workpiece thicknesses). In this utility model, only the needle suction cup 8 is used, and no changes are made to the external or internal structure of the needle suction cup 8, retaining its original function and effect.

[0028] As a preferred embodiment of this utility model, each of the two second mounting plates 4 has a movable opening 13 at the end away from the mounting bracket 1, and each of the two movable openings 13 has an anti-detachment opening 14 on its upper surface. An extension plate 10 is fixedly connected to one side of the mounting block 6, and a guide strip 12 is fixedly connected to the upper surface of the other end of the extension plate 10. The extension plate 10 is slidably connected to the movable opening 13, and the guide strip 12 is slidably connected to the anti-detachment opening 14.

[0029] More specifically, by setting a movable port 13 and an anti-detachment port 14 on the second mounting plate 4, and setting an extension plate 10 and a guide bar 12 on the mounting block 6, the mounting block 6 and the height adjustment rod 5 installed on the mounting block 6 can have a certain degree of front and rear adjustment capability, adapting to the grabbing of more license plates of various sizes.

[0030] As a preferred embodiment of this utility model, the interior of each of the two No. 2 mounting plates 4 is threaded with several clamping knobs 17, and the screw end of the clamping knob 17 passes through the moving port 13 and abuts against the side wall of the extension plate 10.

[0031] More specifically, by setting the clamping knob 17, after adjusting the position of the height adjustment rod 5 on the second mounting plate 4, the clamping knob 17 can be locked, so that the height adjustment rod 5 is not easy to move after adjustment.

[0032] As a preferred embodiment of this utility model, anti-detachment blocks 15 are fixedly connected to both ends of the two extension plates 10. The width of the anti-detachment blocks 15 is greater than the width of the extension plates 10 and the width of the moving opening 13.

[0033] More specifically, by setting the anti-detachment block 15, the extension plate 10 can be prevented from falling out of the moving port 13.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
