Description

Technical Field

[0001] The present application relates to the field of packaging box production, and in particular to a packaging box grabbing arm. Background Art

[0002] A packaging box is a box used to package products. Packaging boxes can be classified into paper boxes, iron boxes, wooden boxes, leather boxes, etc. according to the materials. Its function is to ensure the safety of products during transportation and improve the grade of products.

[0003] The production process of packaging boxes often requires multiple steps, and the connection between these steps often requires circulation through conveyor belts. In general, in order to keep the front and back of the packaging boxes consistent during the circulation process, a robotic arm is required to flip the packaging boxes. However, when the robotic arm grabs the packaging box, it is often necessary to temporarily stop the movement of the conveyor belt in order to accurately grab the packaging box, which will seriously affect the overall work efficiency.

[0004] To this end, we proposed a packaging box grasping arm to solve the above problems. Utility Model Content

[0005] The object of the present application is to adjust the front and back sides of the packaging box without interrupting work. Compared with the prior art, a packaging box grabbing arm is provided, including a conveyor belt assembly, and the left and right side walls of the conveyor belt assembly are fixedly installed with an adjustment assembly, the adjustment assembly includes a fixed crossbeam, and the fixed crossbeam is provided with a slide groove near one side wall of the conveyor belt assembly, and both ends of the slide groove are fixedly installed with an electric telescopic rod, the extended end of the electric telescopic rod is fixedly connected with a slider, and the slider is fixedly connected with a flip assembly near the side wall of the conveyor belt assembly, and the flip assembly includes a fixed rod fixedly connected to the slider, and the fixed rod principle is that one end of the fixed crossbeam is rotatably connected to an extension rod through an electric rotating shaft, and the extension rod is rotatably connected to a rotating disk away from a side wall of the electric telescopic rod, and the electric rotating shaft is used to drive the extension rod to rotate downward to block and isolate the packaging box with the wrong posture separately, and the electric telescopic rod is extended so that the slider drives the flip assembly to clamp and fix the packaging box, and then the electric rotating shaft is used to drive the extension rod and the packaging box to flip upward, so as to avoid hindering the movement of the packaging box behind, thereby improving the fluency of the overall work, and cooperating with the rotating disk to flip and adjust the posture of the packaging box, so as to achieve the uniformity of the posture of the packaging box.

[0006] Furthermore, the fixed crossbeam is fixedly connected to the side wall of the conveyor belt assembly through a pair of connecting rods.

[0007] Furthermore, the length of the fixing rod does not exceed one eighth of the width of the conveyor belt assembly, which effectively prevents the fixing rod from hindering the movement of the packaging box.

[0008] Furthermore, the rotating disk is located in the middle of the conveyor belt assembly, which can clamp the packaging box better and more accurately, ensuring that the rotating disk is clamped at the best force point with the greatest possibility.

[0009] Furthermore, a high-definition camera is installed on the upper end of the fixed beam, and the high-definition camera is electrically connected to an analysis module. The analysis module is connected to an external controller. The high-definition camera is used to capture the image, and the analysis module is used to accurately judge the posture of the packaging box to determine whether it is necessary to start the adjustment component to adjust the passing packaging box.

[0010] Furthermore, a servo motor corresponding to the position of the rotating disk is installed near the side wall of the extension rod near the electric telescopic rod. The output end of the servo motor passes through the extension rod and is fixedly connected to the rotating disk. The servo motor can automatically flip a certain angle to adjust the posture of the packaging box, thereby improving the smoothness and stability of the work.

[0011] Furthermore, the rotating disk includes a fixed disk fixedly connected to the output end of the servo motor, the fixed disk is sealed and connected to the contact disk through a compression bag, the contact disk is elastically connected to the fixed disk through a compression spring, and the contact disk is provided with a plurality of protrusions away from the side wall of the fixed disk. A sealed cavity is formed by the fixed disk, the compression bag and the contact disk. When the rotating disk is clamped to the packaging box, the sealed cavity is squeezed and deformed, which alleviates the impact on the packaging box and effectively avoids deformation and damage of the packaging box, making the clamping force more stable, and the compression spring improves the stability of the rotating disk.

[0012] Furthermore, the diameter of the fixed plate exceeds the diameter of the contact plate by 2-4 cm. When the contact plate is subjected to a large clamping force, it can be embedded inwardly into the compression capsule, so that the compression capsule contacts the packaging box, increasing the contact area, improving the clamping stability, and reducing damage to the packaging box.

[0013] Compared with the prior art, the advantages of this application are:

[0014] 1. Use the electric shaft to drive the extension rod to rotate downward to block and isolate the packaging box with the wrong posture. The electric telescopic rod is extended to make the slider drive the flip assembly to clamp and fix the packaging box.

[0015] 2. A sealed cavity is formed by the fixed disk, the compression bag and the contact disk. When the rotating disk clamps the packaging box, the sealed cavity is squeezed and deformed, which alleviates the impact on the packaging box, effectively avoids the deformation and damage of the packaging box, and makes the clamping force more stable.

[0025] The utility model provides a packaging box grabbing arm, see Figure 1-2, including a conveyor belt assembly 1, the left and right side walls of the conveyor belt assembly 1 are fixedly installed with an adjustment assembly 2, the adjustment assembly 2 includes a fixed crossbeam 21, the fixed crossbeam 21 is provided with a slide groove 211 on one side wall close to the conveyor belt assembly 1, electric telescopic rods 23 are fixedly installed on both ends of the slide groove 211, the extended end of the electric telescopic rod 23 is fixedly connected with a slider 24, the slider 24 is fixedly connected with a flip assembly 25 close to the side wall of the conveyor belt assembly 1, the flip assembly 25 includes a fixed rod 251 fixedly connected to the slider 24, the fixed rod 251 is rotatably connected to an extension rod 253 at one end of the fixed crossbeam 21 through an electric rotating shaft 252, and the extension rod 253 is rotatably connected to a rotating disk 26 on a side wall away from the electric telescopic rod 23.

[0026] For details, please refer to Figure 2-3 The electric rotating shaft 252 is used to drive the extension rod 253 to rotate downward to block and isolate the packaging boxes with wrong postures. The electric telescopic rod 23 is extended to allow the slider 24 to drive the flip assembly 25 to clamp and fix the packaging box. Then, the electric rotating shaft 252 is used to drive the extension rod 253 and the packaging box to flip upward to avoid hindering the movement of the packaging boxes behind, thereby improving the smoothness of the overall work. The rotating disk 26 is used to flip and adjust the posture of the packaging box to achieve the uniform posture of the packaging box.

[0027] The fixed cross beam 21 is fixedly connected to the side wall of the conveyor belt assembly 1 through a pair of connecting rods 22 .

[0028] The length of the fixing rod 251 does not exceed one eighth of the width of the conveyor belt assembly 1, which effectively prevents the fixing rod 251 from hindering the movement of the packaging box.

[0029] The rotating disk 26 is located in the middle of the conveyor belt assembly 1, so that the packaging box can be clamped better and more accurately, ensuring that the rotating disk 26 is clamped at the best force point with the greatest possibility.

[0030] A high-definition camera is installed on the upper end of the fixed beam 21. The high-definition camera is electrically connected to an analysis module. The analysis module is connected to an external controller. The high-definition camera is used to capture images and cooperate with the analysis module to accurately judge the posture of the packaging box to determine whether it is necessary to start the adjustment component 2 to adjust the passing packaging box.

[0031] See also Figure 2 A servo motor 254 corresponding to the position of the rotating disk 26 is installed on the extension rod 253 near the side wall of the electric telescopic rod 23. The output end of the servo motor 254 passes through the extension rod 253 and is fixedly connected to the rotating disk 26. The servo motor 254 can automatically flip a certain angle to adjust the posture of the packaging box, thereby improving the smoothness and stability of the work.

[0032] Working principle: the extension rod 253 is in a vertical state under normal conditions, and a high-definition camera is used to capture the image, and the analysis module is used to accurately determine the posture of the packaging box. When a packaging box with an incorrect posture is found to pass through the adjustment component 2, the electric shaft 252 is controlled to drive the extension rod 253 to rotate downward to block and isolate the packaging box with the incorrect posture. The electric telescopic rod 23 is controlled to extend so that the slider 24 moves along the slide groove 211, driving the extension rod 253 to clamp and fix the packaging box. Then, the electric shaft 252 is used to drive the extension rod 253 and the packaging box to flip upward 90 degrees. The servo motor 254 automatically rotates a certain angle to adjust the posture of the packaging box. Finally, the electric shaft 252 is controlled to place the packaging box in the empty position on the conveyor assembly 1, and finally the extension rod 253 and the electric telescopic rod 23 are reset. Embodiment 2:

[0033] The utility model provides a packaging box grabbing arm, see Figure 4 The rotating disk 26 includes a fixed disk 261 fixedly connected to the output end of the servo motor 254. The fixed disk 261 is sealed and connected to the contact disk 262 through a compression bag 263. The contact disk 262 is elastically connected to the fixed disk 261 through a compression spring 265. The contact disk 262 is provided with a plurality of protrusions 264 away from the side wall of the fixed disk 261.

[0034] Specifically, a sealed cavity is formed by the fixed disk 261, the compression bag 263 and the contact disk 262. When the rotating disk 26 is clamped to the packaging box, the sealed cavity is squeezed and deformed, which alleviates the impact on the packaging box and effectively avoids deformation and damage of the packaging box, making the clamping force more stable. The compression spring 265 improves the stability of the rotating disk 26.

[0035] The diameter of the fixed plate 261 exceeds the diameter of the contact plate 262 by 2-4 cm. When the contact plate 262 is subjected to a large clamping force, it can be embedded inwardly into the compression capsule 263, so that the compression capsule 263 contacts the packaging box, thereby increasing the contact area, improving the clamping stability, and reducing damage to the packaging box.

[0036] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
