Description

Technical Field

[0001] This utility model relates to a flipping and pushing device for license plates, belonging to the technical field of license plate production equipment. Background Technology

[0002] In the license plate production industry, after mechanical processing and equipment endorsement, license plates need to be boxed, handled, packaged, and stacked. Currently, license plates are endorsed using specialized equipment, and once a box is full of a specified number of endorsed plates, they are manually transported to a conveyor line for packaging. In this operational mode, because license plate production and packaging often require continuous operation (such as batch stamping, license plate endorsement, full-box handling, and packaging stacking, all processes need to be completed in batches), if manual handling is used during the processing, operators must constantly monitor whether the boxes are full before manually transferring them. Otherwise, it will affect the production schedule of the next box. This process involves a high degree of manual intervention, resulting in low production efficiency and quality control. Especially when facing large-volume production demands, not only do operators need to continuously handle full-box transfers of license plates, leading to high labor intensity and significantly increased labor costs, but the intermittent and inefficient nature of manual operation can also easily cause production process disruptions, affecting overall production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a flipping and pushing device for license plates. This invention automates the loading and transfer of license plates into boxes, reducing labor costs.

[0004] The technical solution of this utility model: a flipping and pushing device for license plates, including a base frame, bearing plates symmetrically arranged on both sides of the rear end of the base frame, and an L-shaped frame body rotatably connected between the two bearing plates; a first connecting seat is provided on the base frame, and a cylinder is rotatably connected to the first connecting seat; a first connecting plate is fixedly connected to the outer side of the L-shaped frame body, and the first connecting plate is rotatably connected to the extended end of the first cylinder; a first push plate and a second push plate are slidably connected to the two straight surfaces of the L-shaped frame body, and a push mechanism is provided between the first push plate, the second push plate and the L-shaped frame body; the first push plate is close to the side of the L-shaped frame body connected to the first connecting plate.

[0005] The aforementioned flipping and pushing device for license plates includes a pushing mechanism comprising a second cylinder fixedly connected to an L-shaped frame, guide rods symmetrically arranged on both sides of the second cylinder, a slider slidably connected to the guide rod, and the slider being fixedly connected to the corresponding pushing plate; a second connecting plate is connected to the output end of the second cylinder, and the second connecting plate is fixedly connected to the corresponding pushing plate.

[0006] The aforementioned flipping and pushing device for license plates has a first bending section with a Z-shaped cross-section on the left side of the first pushing plate, and the bending direction of the first bending section is away from the corresponding straight surface of the L-shaped frame.

[0007] The aforementioned flipping and pushing device for license plates has a second bending section with an L-shaped cross-section on the front side of the second push plate, and the bending direction of the second bending section is toward the corresponding straight surface of the L-shaped frame.

[0008] The aforementioned flipping and pushing device for license plates has multiple pads threadedly connected to the bottom of the base frame, and the lower end of the pads is provided with cushioning cotton.

[0009] The aforementioned flipping and pushing device for license plates has a groove on the L-shaped frame that is located on the same vertical plane as the second cylinder.

[0010] Compared with the prior art, the present invention has the following beneficial effects: Before use, the first cylinder is retracted, causing the side of the L-shaped frame connected to the first connecting plate to rotate until it contacts the base frame. Then, the packaging box is placed on the first push plate, with the opening of the packaging box a certain distance away from the second push plate and close to the card outlet of the external case packing machine, ensuring that the empty packaging box is in the appropriate position on the first push plate. Afterward, the external automatic case packing machine pushes the full box of license plates onto the first push plate. The extended end of the first cylinder extends, causing the L-shaped frame to rotate around the bearing plate until the other vertical surface contacts the base frame, completing a 90° flip. After the flip, the packaging box and license plates change from a horizontal state to a vertical state, and the license plates fall into the packaging box. Finally, the push mechanism pushes the second push plate outward so that it can interact with the external AGV robot for handling operations. Attached Figure Description

Detailed Implementation

[0014] 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.

[0015] Example: A flipping and pushing device for license plates, configured as follows Figure 1-2As shown, the device includes a base frame 1 made of high-strength steel, which is sturdy and durable and can withstand various loads during operation. Bearing plates 2 are symmetrically arranged on both sides of the rear end of the base frame 1. An L-shaped frame 3 made of lightweight, high-strength aluminum alloy is rotatably connected between the two bearing plates 2. The aluminum alloy material ensures the strength of the frame while reducing the overall weight and energy consumption. Figure 2 As shown, the base frame 1 is provided with a first connecting seat 4, and a cylinder is rotatably connected to the first connecting seat 4; a first connecting plate 6 is fixedly connected to the outer side of the L-shaped frame 3, and the first connecting plate 6 is rotatably connected to the extended end of the first cylinder 5. The L-shaped frame can be rotated by the extension and retraction of the first cylinder 5; a first ejector plate 7 and a second ejector plate 8 are slidably connected to the two straight surfaces of the L-shaped frame 3, and an ejection mechanism 9 is provided between the first ejector plate 7 and the second ejector plate 8 and the L-shaped frame 3; the first ejector plate 7 is located near the side of the L-shaped frame 3 connected to the first connecting plate 6. The second ejector plate 8 is provided with a sensing device, such as a touch button or an infrared sensor, to detect whether the packaging box touches the second ejector plate 8. Before use, first retract the first cylinder 5, causing the side of the L-shaped frame connected to the first connecting plate 6 to rotate until it abuts against the base frame 1. Then, place the packaging box horizontally on the first push-out plate 7, with the opening of the packaging box at a suitable distance from the second push-out plate 8. Next, push the first push-out plate 7 outward a suitable distance using the push-out mechanism 9, ensuring that the packaging box is at the appropriate distance from the first push-out plate 7. Afterward, the production equipment pushes the produced license plate onto the first push-out plate 7. When the packaging box approaches the sensing device of the second push-out plate, the extended end of the first cylinder 5 extends, causing the L-shaped frame to rotate around the bearing plate 2 until the other vertical surface contacts the base frame 1, completing a 90° flip. During the flip, the packaging box and license plate on the first push-out plate 7 change from a horizontal state to a vertical state, and the license plate falls into the packaging box. Finally, the second push-out plate 8 of the push-out mechanism 9 pushes outward to complete the interactive handling of the packaging box with the AGV and the flipping device.

[0016] Preferably, such as Figure 2 As shown, the ejection mechanism 9 includes a second cylinder 90 fixedly connected to the L-shaped frame 3. Symmetrically arranged on both sides of the second cylinder 90 are guide rods 91 made of high-quality carbon steel. The surfaces of the guide rods 91 are chrome-plated to reduce the coefficient of friction. A slider 92 is slidably connected to the guide rod 91, and the slider 92 is fixedly connected to the corresponding ejection plate. A second connecting plate 93 is connected to the output end of the second cylinder 90, and the second connecting plate 93 is fixedly connected to the corresponding ejection plate. The second cylinder 90 drives the second connecting plate 93 to move, and the second connecting plate 93 drives the corresponding ejection plate to move. Utilizing the linear driving force of the second cylinder 90, combined with the sliding of the slider 92 on the guide rod 91, the slider 92 and guide rod 91 ensure stable displacement, guaranteeing accurate positioning of the corresponding ejection plate during the ejection process without deviation.

[0017] Preferably, such as Figure 1 As shown, the left side of the first ejector plate 7 is provided with a first bend 10 with a Z-shaped cross-section, and the bending direction of the first bend 10 is away from the corresponding straight surface of the L-shaped frame 3. When placing the packaging box, its side abuts against the first bend 10, thereby fixing the initial position of the packaging box. This facilitates adjusting the appropriate connection position when the production equipment number plate is ejected, so that the number plate can be pushed into the packaging box more accurately, improving the accuracy and efficiency of packing.

[0018] Preferably, such as Figure 1 As shown, the front side of the second ejector plate 8 is provided with a second bending portion 11 with an L-shaped cross-section, and the bending direction of the second bending portion 11 is towards the corresponding straight surface of the L-shaped frame 3. The second bending portion 11 is used to limit the range of inward movement of the second ejector plate 8, and prevents it from moving too far inward and colliding with the first ejector plate 7 by means of physical blocking, so as to avoid damage to the components due to excessive movement.

[0019] Preferably, such as Figure 1 As shown, the bottom of the base frame 1 is connected to multiple feet 12 by threads. The height of the base frame 1 can be adjusted by rotating the feet 12 to adapt to different ground conditions and work requirements. The lower end of the feet 12 is provided with a cushioning cotton 13 made of rubber material. The cushioning cotton 13 absorbs vibration by utilizing its elastic deformation to reduce vibration during the operation of the device, reduce noise, and enhance the stability of the device to prevent the packaging box and license plate from shifting due to vibration.

[0020] Preferably, such as Figure 2 As shown, the L-shaped frame 3 is provided with a groove 14 located on the same vertical plane as the second cylinder 90. The groove 14 is used to prevent the first cylinder 5 from interfering with or colliding with the L-shaped frame 3 during operation.

[0021] Working principle:

[0022] Before use, the first cylinder 5 retracts, causing one side of the L-shaped frame connected to the first connecting plate 6 to rotate until it contacts the base frame 1, forming a stable horizontal placement surface. The packaging box is then placed horizontally on the first push-out plate 7, with the opening at a suitable distance from the second push-out plate 8. Subsequently, the second cylinder 90 in the push-out mechanism 9 drives the second connecting plate 93, causing the first push-out plate 7 to be pushed outward a suitable distance, which ensures that the packaging box is placed stably.

[0023] When the production equipment pushes the full box of license plates to the first push plate 7, the first cylinder 5 extends and pushes the L-shaped frame to rotate 90° around the bearing plate 2 until the other vertical surface contacts the base frame 1; finally, the second cylinder 90 of the push mechanism 9 works again, driving the second push plate 8 to push outward, pushing the box full of license plates to a suitable position, which is convenient for AGV robots and other equipment to handle.

[0024] In the ejection mechanism 9, the guide rods 91 on both sides of the second cylinder 90 cooperate with the slider 92 to provide guidance and stable support for the movement of the ejection plate, ensuring accurate movement of the ejection plate; the Z-shaped first bend 10 of the first ejection plate 7 fixes the initial position of the packaging box through mechanical limiting, which facilitates the accurate placement of the license plate into the box; the L-shaped second bend 11 of the second ejection plate 8 limits its inward movement range to prevent collision with the first ejection plate 7; the pads 12 at the bottom of the base frame 1 are height-adjustable to adapt to different ground conditions, and the cushioning cotton 13 at the bottom can reduce vibration and improve the stability of the device; the groove 14 on the L-shaped frame body, through reasonable space design, avoids interference and collision between the first cylinder 5 and the frame body when working, ensuring coordinated operation of all components.
