Description

Technical Field

[0001] This utility model relates to the field of cardboard box production, and in particular to a clamping assembly for material stacking. Background Technology

[0002] With the rapid development of the cardboard box manufacturing industry, how to efficiently and accurately stack cardboard boxes has become a focus of attention for enterprises. Traditional stacking methods often rely on manual operation, which is not only inefficient but also poses safety hazards. Therefore, automated cardboard box stacking fixtures have emerged to replace manual operation and improve stacking efficiency and safety.

[0003] In existing carton palletizing fixtures, most rely on gripper cylinders to move and grip the two grippers. The working principle of this method is to use the extension and retraction of the cylinder to push the grippers open and close, thereby gripping the carton. However, this method has some limitations. The extension and retraction speed and force control of the cylinder are relatively limited, making it difficult to achieve high-precision gripping and positioning. At the same time, the maintenance cost of the cylinder is high, and there are potential risks such as leakage.

[0004] Therefore, it is necessary to propose a clamping assembly for material palletizing to solve the above problems. Utility Model Content

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1-6As shown, a clamping assembly for material palletizing includes a mounting frame 1 connected to a palletizing robot. Specifically, a mounting base 2 is bolted to the top of the mounting frame 1, and the mounting frame 1 is bolted to the palletizing robot via the mounting base 2. A servo mechanism is provided at the upper end of the mounting frame 1, and a gripping mechanism driven by the servo mechanism is provided at the lower end of the servo mechanism. The servo mechanism includes second synchronous pulleys 15 located at both ends of the mounting frame 1, and a first belt 10 is provided on the two second synchronous pulleys 15. A servo motor 4 for driving the rotation of the second synchronous pulleys 15 is provided at one end of the mounting frame 1. Specifically, a fixed frame 9 is provided at one end of the mounting frame 1, and the servo motor 4 is mounted on one side of the fixed frame 9, with the fixed frame 9 facing away from the servo motor 1. A pair of first synchronous pulleys 14 are provided on one side of the servo motor 4, and one of the first synchronous pulleys 14 corresponds to the servo motor 4. The servo motor 4 is used to drive the first synchronous pulley 14 to rotate. A second belt 13 is provided on the outer side of the two first synchronous pulleys 14. One of the second synchronous pulleys 15 is provided on the side of the fixed frame 9 and corresponds to the first synchronous pulley 14 away from the servo motor 4. The second synchronous pulley 15 is coaxially arranged with the first synchronous pulley 14, so that the first synchronous pulley 14 can drive the second synchronous pulley 15 to rotate when it rotates. In order to achieve the tension of the second belt 13, a tensioning pulley 12 corresponding to the second belt 13 is rotatably provided on one side of the fixed frame 9, and the tensioning pulley 12 abuts against the second belt 13.

[0029] Furthermore, the clamping mechanism includes movable frames 6 movably disposed at both ends of the bottom of the mounting frame 1. A clamping plate 3 for clamping materials is vertically disposed at the bottom of the movable frame 6. A connecting arm 11 corresponding to the first belt 10 is disposed on one side of the upper end of the movable frame 6, and the connecting arms 11 on the two movable frames 6 are respectively bolted to the upper and lower ends of the first belt 10, so that the two connecting arms 11 can be displaced in opposite directions when the first belt 10 is running. A first sensor 17 for detecting materials is disposed on the side of the clamping plate 3 used for clamping. In order to reduce clamping damage, a silicone plate 8 is disposed on the side of the clamping plate 3 used for clamping. The silicone plates 8 are evenly distributed, and the sidewall of the silicone plate 8 is provided with protrusions. The first sensor 17 is located in the gap between two of the silicone plates 8, and the first sensor 17 does not protrude from the side of the silicone plate 8.

[0030] In order to achieve the displacement of the movable frame 6, a sensing plate 19 is provided on one side of the upper end of the movable frame 6, and a second sensor 18 corresponding to the sensing plate 19 and used to detect the position of the sensing plate 19 is provided at the bottom of the mounting frame 1.

[0031] To increase the stability of the movable frame 6, a linear guide rail 7 is provided on the bottom side of the mounting frame 1, and a slider 16 is provided on the movable frame 6 for sliding cooperation with the linear guide rail 7.

[0032] In order to protect the transmission parts, a protective cover 5 is provided on the side of the fixed frame 9 away from the servo motor 4 to cover the first synchronous pulley 14 and the second belt 13.

[0033] In use, the mounting base 2 on the top of the mounting frame 1 is bolted onto the palletizing robot. The palletizing robot moves the clamp to the gripping position, so that the two clamping plates 3 are located on one side of the carton. The first sensor 17 detects the position, and the servo motor 4 drives the first synchronous wheel 14 to rotate. The first synchronous wheel 14 drives another first synchronous wheel 14 to rotate through the second belt 13. The first synchronous wheel 14 drives the second synchronous wheel 15 to rotate. The second synchronous wheel 15 drives the first belt 10 to rotate. Then, the first belt 10 drives the two moving frames 6 to move in the opposite direction through the connecting arm 11. The moving frames 6 drive the clamping plates 3 to grip the carton. The second sensor 18, in conjunction with the sensing plate 19, senses that the moving frame 6 has moved to the correct position and stops gripping. The palletizing robot moves the device to the palletizing position. The servo motor 4 reverses, and the clamping plates 3 release the carton. Similarly, the second sensor 18 and the sensing plate 19 sense that the moving frame 6 has moved to the correct position, and the servo motor 4 stops. Then, the carton is moved away again by the palletizing robot, waiting for subsequent gripping.

[0034] The servo mechanism of this device, in conjunction with the gripping mechanism, enables the gripping of materials. The servo motor 4 features high precision, high speed, and high stability control, allowing for precise control of carton gripping. Through belt drive, the rotational motion of the servo motor 4 is converted into the linear motion of the clamping plate 3, thus achieving precise gripping and positioning of the carton. Moreover, the servo motor 4 has high energy conversion efficiency, with a higher energy efficiency ratio compared to a cylinder. This means that under the same gripping task, the clamp driven by the servo motor 4 consumes less energy, achieving higher energy efficiency. Furthermore, the structure of the servo motor 4 and the belt drive system is relatively simple, resulting in lower maintenance costs. At the same time, due to the high control precision of the servo motor 4, the failure rate caused by improper operation or wear can be reduced, thereby lowering maintenance costs. In addition, the servo motor 4 can be programmed to achieve different gripping modes and speed control, adapting to cartons of different sizes and weights. This flexibility allows the clamp to cope with various palletizing requirements, improving the adaptability and flexibility of the production line.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
