Abstract
Description
Technical Field
[0001] This utility model relates to the field of label pasting technology, and in particular to a robotic arm structure for automatic label pasting of plastic products. Background Technology
[0002] In the production of plastic products, various product information labels need to be affixed to the products. Currently, robotic arms are often used to affix these labels.
[0003] When using a robotic arm to affix labels, a suction cup is used to adhere the label paper. The robotic arm then moves the label paper to the product location and affixes it to the product. Existing suction cups generally have a flat structure, allowing the label paper to be held flat on the suction cup. However, when affixing labels to non-flat areas of the product, the traditional flat suction cup structure is limited by its shape. To ensure a firm adhesion, the robotic arm needs to move left and right and push the label paper to ensure stable adhesion to the product, which affects the label affixing efficiency. Utility Model Content

[0005] Therefore, one objective of this utility model is to propose a robotic arm structure for automatically labeling plastic product labels, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of this utility model provides a robotic arm structure for automatically labeling plastic product labels, including a base, a robotic arm mounted on the base, a mounting plate at the end of the robotic arm, a fixed suction plate fixedly connected to the mounting plate, a movable suction plate rotatably connected to the side of the fixed suction plate, and a coil spring between the movable suction plate and the fixed suction plate; an electric push rod is mounted on the mounting plate, a movable frame is fixedly connected to the output end of the electric push rod, a push rod is threaded onto the movable frame, the push rod passes through the mounting plate, an air extraction assembly is mounted on the robotic arm, and exhaust pipes are provided inside both the fixed suction plate and the movable suction plate.
[0007] The above technical solution involves the following steps: When labeling non-planar products, the push rod is pre-rotated to adjust its position according to the product shape, enabling it to drive the movable suction plate to rotate and adapt to the product's shape. During labeling, the label paper is first adsorbed using the flat fixed and movable suction plates. A robotic arm moves the label paper to the product position and presses it onto the product. Subsequently, an electric push rod moves the movable frame, which in turn moves the push rod. The push rod then rotates the movable suction plate, causing it to push the label paper onto the product, completing the labeling process. This eliminates the need for a robotic arm to move left and right to push the label paper onto the product, saving time and increasing efficiency.
[0008] Preferably, in any of the above embodiments, the top and bottom of the movable suction plate are provided with a sleeve frame, and the coil spring is disposed within the sleeve frame.

[0010] Preferably, in any of the above solutions, the movable suction plate adopts a U-shaped structure, and the movable suction plate includes several single plates that are rotatably connected in sequence, with coil springs also provided between adjacent single plates.
[0011] The above technical solution employs a multi-stage movable suction plate, which can accommodate products of more shapes. Springs are also installed between the individual plates of the movable suction plate, so that the entire movable suction plate can remain horizontal when no external force is applied, making it convenient for the device to adsorb the label paper.
[0012] Preferably, as described in any of the above embodiments, movable suction plates are provided on both sides of the fixed suction plate, and electric push rods are provided on both sides of the mounting plate.
[0013] The above technical solution involves setting movable suction plates on both sides of the fixed suction plate, so that when the suction cup is centered on the fixed suction plate, the label paper is fixedly adsorbed in the middle, making the adsorption more stable.
[0014] Preferably, in any of the above solutions, the movable frame adopts an H-shaped structure and is located on the side of the mounting plate away from the movable suction plate.
[0015] The above technical solution is adopted: the movable frame provides an installation platform for the push rod, and its H-shaped structure ensures that the setting of the push rod is not affected by the electric push rod.
[0016] Preferably, in any of the above embodiments, the rear end of the push rod is fixedly connected to a rotating handle, and the front end of the push rod is provided with a buffer head.
[0017] The above technical solution employs a handle at the rear end of the push rod for easy rotation by the user. A buffer head is provided at the front end to cushion the movement between the push rod and the moving plate, preventing excessive wear from hard contact.
[0018] Preferably, in any of the above schemes, the number of push rods is the same as the number of movable suction plates or an integer multiple of the number of movable suction plates.
[0019] The above technical solution involves setting multiple push rods corresponding to the movable suction plates, so that each movable suction plate can be pushed by an individual push rod.
[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0021] 1. This robotic arm structure for automatically labeling plastic products utilizes a mounting plate, fixed suction plate, movable suction plate, coil spring, electric push rod, movable frame, and push rod. When labeling non-flat products, the push rod is pre-positioned according to the product shape, allowing it to rotate and align with the movable and fixed suction plates.

Then, the electric push rod moves the movable frame, which in turn moves the push rod, which in turn rotates the movable suction plate, pushing the label onto the product. This eliminates the need for the robotic arm to move left and right to adhere the label, saving time and increasing efficiency.
[0022] 2. The robotic arm structure for automatically labeling plastic products features a frame on the movable suction plate that provides a mounting platform and space for the coil springs, while also protecting them and promoting their long-term use.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] like Figures 1-4 As shown, this utility model includes a base 1, a robotic arm 2 mounted on the base 1, a mounting plate 3 at the end of the robotic arm 2, a fixed suction plate 4 fixedly connected to the mounting plate 3, a movable suction plate 5 rotatably connected to the side of the fixed suction plate 4, and a coil spring 6 between the movable suction plate 5 and the fixed suction plate 4; an electric push rod 7 mounted on the mounting plate 3, a movable frame 8 fixedly connected to the output end of the electric push rod 7, a push rod 9 threadedly connected to the movable frame 8, the push rod 9 penetrating the mounting plate 3, an air extraction assembly 10 mounted on the robotic arm 2, and an exhaust pipe 11 inside both the fixed suction plate 4 and the movable suction plate 5.
[0033] When affixing labels to non-flat products, the position of the push rod 9 is pre-adjusted according to the product shape, allowing the push rod 9 to drive the movable suction plate 5 to rotate, adapting the movable suction plate 5 to the shape of the fixed suction plate 4. During the affixing process, the label paper is first adsorbed using the flat fixed suction plate 4 and movable suction plate 5. The robotic arm 2 moves the label paper to the product position and presses it onto the product. Then, the electric push rod 7 drives the movable frame 8 to move, which in turn drives the push rod 9 to move. The push rod 9 pushes the movable suction plate 5 to rotate, causing the movable suction plate 5 to push the label paper onto the product, completing the affixing process. This eliminates the need for the robotic arm to move left and right to push the label paper onto the product, saving affixing time and increasing efficiency.
[0034] Example 1: The top and bottom of the movable suction plate 5 are provided with sleeve frames, and the coil spring 6 is set inside the sleeve frames. The movable suction plate 5 adopts a U-shaped structure and includes several single plates that are rotatably connected in sequence. Coil springs 6 are also provided between adjacent single plates.
[0035] Specifically: The frame on the movable suction plate 5 provides an installation platform and space for the coil spring 6, and also provides protection for the coil spring 6, which is beneficial to the long-term use of the coil spring 6. The movable suction plate 5, which adopts a multi-level structure formed by multiple single plates rotating and connected to each other, can adapt to products of more shapes. Coil springs 6 are also set between the single plates of the movable suction plate 5, so that the movable suction plate 5 as a whole can maintain a horizontal state when no external force is applied, which facilitates the device to adsorb the label paper.
[0036] Example 2: Movable suction plates 5 are provided on both sides of the fixed suction plate 4, and electric push rods 7 are provided on both sides of the mounting plate 3. The movable frame 8 adopts an H-shaped structure and is located on the side of the mounting plate 3 away from the movable suction plates 5.
[0037] Specifically: Movable suction plates 5 are provided on both sides of the fixed suction plate 4, so that the suction cup is centered on the fixed suction plate 4, and when adsorbing label paper, the label paper is fixedly adsorbed in the middle, making the adsorption more stable. The movable frame 8 provides an installation platform for the push rod 9, and its H-shaped structure ensures that the setting of the push rod 9 is not affected by the electric push rod 7.
[0038] Example 3: A rotating handle is fixedly connected to the rear end of the push rod 9, and a buffer head is provided at the front end of the push rod 9. The number of push rods 9 is the same as the number of movable suction plates 5 or an integer multiple of the number of movable suction plates 5.
[0039] Specifically: A handle is provided at the rear end of the push rod 9 for easy rotation by the user. When adjusting the position of the push rod 9, the user can hold the handle and rotate it to change its position. A buffer head is provided at the front end of the push rod 9. The buffer head can be deformed under pressure, providing cushioning between it and the movable plate 5 and avoiding excessive wear caused by hard contact between the two. Multiple push rods 9 are provided corresponding to the movable suction plates 5, so that each movable suction plate 5 can be pushed by an individual push rod 9.
[0040] The working principle of this utility model is as follows:
[0041] S1. According to the product shape, pre-rotate the push rod 9 to adjust its position so that the push rod 9 can push the movable suction plate 5 to rotate, so that the movable suction plate 5 and the fixed suction plate 4 can match the shape of the product.
[0042] S2. When pasting, first use the flat fixed suction plate 4 and movable suction plate 5 to adsorb the label paper, and the robotic arm 2 moves the label paper to the product position.
[0043] S3. First, press the label onto the product. Then, the electric push rod 7 drives the movable frame 8 to move, the movable frame 8 drives the push rod 9 to move, and the push rod 9 pushes the movable suction plate 5 to rotate, so that the movable suction plate 5 pushes the label onto the product, completing the pasting.

This robotic arm structure for automatically labeling plastic products comprises a mounting plate 3, a fixed suction plate 4, a movable suction plate 5, a coil spring 6, an electric push rod 7, a movable frame 8, and a push rod 9. When labeling non-flat products, the push rod 9 is pre-positioned according to the product shape, allowing it to drive the movable suction plate 5 to rotate, thus adapting the movable suction plate 5 to the shape of the fixed suction plate 4. During labeling, the fixed suction plate 4 and movable suction plate 5, in their flat state, first adhere the label. The robotic arm 2 moves the label to the product position and presses it onto the product. Then, the electric push rod 7 moves the movable frame 8, which in turn moves the push rod 9. The push rod 9 pushes the movable suction plate 5 to rotate, causing it to adhere the label to the product, completing the labeling process. This eliminates the need for the robotic arm to move left and right to push the label onto the product, saving time and increasing efficiency.
