Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo sorting, specifically to a cargo identification device for a sorting robotic arm. Background Technology
[0002] Goods are transported at intervals on a conveyor belt, and by installing robotic arms, large quantities of goods can be sorted instead of manually.
[0003] Labels that are easy to identify are placed on boxes and bags. However, after goods are placed on the conveyor belt manually or mechanically, the only guarantee is that the goods are placed facing upwards. Labels are often randomly pasted on the goods. Furthermore, aligning the goods on the conveyor belt will reduce sorting efficiency.
[0004] The cameras of the corresponding scanning and recognition instruments on the sorting equipment are usually fixedly installed, mostly facing downwards, with a few placed on one side of the goods. They are always unable to effectively capture information from other sides of the goods, which leads to some goods not being recognized and thus unable to be correctly sorted by the robotic arm. Therefore, a sorting robotic arm goods recognition device is provided. Utility Model Content
[0005] I. Technical problems to be solved
[0006] The technical problem this invention aims to solve is that labels attached to goods in conjunction with robotic arms for sorting are generally pasted haphazardly, and calibrating the placement of goods on the conveyor belt also consumes manpower and resources, reducing work efficiency.

[0010] The base frame is equipped with a longitudinal capture mechanism that enables the camera mounted on the bracket to rotate on both sides of the cargo below.
[0011] The bottom of the bracket is connected to an arc-shaped inner guide frame, on which a slider for directly supporting the camera is connected. The bracket is equipped with a lateral capture mechanism that causes the slider to move along the inner guide frame, thereby enabling the slider to drive the camera to rotate on the left and right sides of the cargo below.
[0012] Furthermore, the longitudinal capture mechanism includes a drive shaft connected to both sides of the bottom end of the support and rotatably connected to the base frame, and a No. 1 motor that drives and cooperates with the drive shaft is installed on one side of the base frame.

A positioning piece is provided at one end of the sliding column that passes through the outer guide frame.
[0014] Furthermore, the lateral capture mechanism includes a screw rotatably connected to the top of the bracket, a second motor that drives and cooperates with the screw is installed on one side of the bracket, a threaded sleeve is threadedly connected to the screw, a limiting component is connected to the bracket to prevent the threaded sleeve from rotating and to provide auxiliary support for components such as the telescopic rod, and a telescopic rod with its bottom end rotatably connected to the slider is connected below the threaded sleeve.
[0015] Furthermore, the limiting component includes a slide rail located on the top of the bracket, and the top of the screw sleeve is connected to a hanger that slides through the slide rail and is slidably connected to the bracket.
[0016] Furthermore, the telescopic rod is composed of a hanging rod connected below the screw sleeve and a sliding cylinder rotatably connected above the slider.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.
[0028] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a sorting robotic arm cargo identification device, combined with an appendix... Figure 1-2 The system includes a base frame 1 with an internal transmission mechanism. The cargo sorting robot arm is installed on one side of the base frame 1. The cargo is placed on the conveyor belt by manual labor or feeding equipment. During transportation, the cargo is grabbed by the sorting robot arm and placed in the corresponding storage mechanism. The sorting robot arm and the conveyor mechanism are both within the scope of existing technology and will not be described in detail here. The robot arm is generally installed or placed on the ground on one side of the conveyor belt. Depending on the needs, one or more robots are used.
[0029] A bracket 6 is rotatably connected above the base frame 1. A camera 10 is installed downward inside the bracket 6 for scanning and identifying the goods on the transmission mechanism and sorting them with the robotic arm. The camera 10 is the main component of the scanning device for taking pictures and authenticating the identification codes affixed to the goods. Since this application mainly improves the scanning position of the camera 10, only the camera 10 is highlighted here.
[0030] The device can be simply understood as the camera 10 providing a flexible frame or platform, which is mounted on the base frame 1 and, from the appearance, is integrated with the transmission mechanism. It is to be placed before the goods are conveyed to the robotic arm sorting area.
[0031] The base frame 1 is connected to external guide frames 2 in an arc shape on both sides, combined with the attached... Figure 6 The bracket 6 is connected to two sides by sliding columns 4 embedded in the outer guide frame 2 to provide auxiliary support. One end of the sliding column 4 that passes through the outer guide frame 2 is connected to a positioning piece 5.
[0032] The base frame 1 is equipped with a longitudinal capturing mechanism that causes the bracket 6 carrying the camera 10 to rotate on both sides of the cargo below, combined with the attached... Figure 5 The longitudinal capture mechanism includes a drive shaft 7 connected to both sides of the bottom end of the bracket 6 and rotatably connected to the base frame 1. A No. 1 motor 8 is installed on one side of the base frame 1 and is mutually driven and cooperates with the drive shaft 7.
[0033] As motor 8 operates, the drive shaft 7 causes the bracket 6 containing camera 10 to rotate in the same direction as the movement path of the goods. The camera 10, which originally shot vertically downwards, changes its shooting angle after such rotation, which can effectively capture, photograph and scan the information pasted on the front and back sides of the goods.
[0034] The bottom of the bracket 6 is connected to an arc-shaped inner guide frame 3, which is combined with the attached... Figure 4 The inner guide frame 3 is connected to a slider 9 for directly supporting the camera 10. Similar to the front and rear shooting of the camera 10 mentioned above, the slider 9 carries the camera 10 and moves within the inner guide frame 3, which can also change the shooting angle. Since the inner guide frame 3 and the outer guide frame 2 are arranged perpendicular to each other, this part of the mechanism can effectively capture, photograph, and scan the information pasted on the left and right sides of the goods.
[0035] The bracket 6 is equipped with a lateral capture mechanism that causes the slider 9 to move along the inner guide frame 3, thereby enabling the slider 9 to drive the camera 10 to rotate on the left and right sides of the cargo below. The lateral capture mechanism includes a screw 11 rotatably connected to the top of the bracket 6. A second motor 12, which is mutually driven and cooperates with the screw 11, is installed on one side of the bracket 6. Figure 3 The screw 11 is threadedly connected to a screw sleeve 13, and the bracket 6 is connected to a limiting component for preventing the screw sleeve 13 from rotating and also for providing auxiliary support for components such as telescopic rods. The limiting component includes a slide rail 15 located on the top of the bracket 6, and a hanger 14 is connected to the top of the screw sleeve 13 through the slide rail 15 and slidably connected to the bracket 6.
[0036] The threaded sleeve 13 is connected to a telescopic rod whose bottom end is rotatably connected to the slider 9. The telescopic rod is composed of a hanging rod 16 connected to the bottom of the threaded sleeve 13 and a sliding cylinder 17 rotatably connected to the top of the slider 9. The sliding cylinder 17 is provided with sliding grooves 18 on all four sides. The bottom end of the hanging rod 16 extends into the sliding cylinder 17 and passes through the sliding grooves 18 to maintain a sliding connection with the sliding cylinder 17.
[0037] The second motor 12 runs, causing the screw 11 to rotate. Due to the limiting conditions between the screw sleeve 13 and the bracket 6 on the screw 11, it can only carry the slider 9 and the camera 10 below and move along the axial direction of the screw 11, that is, perpendicular to the direction of the goods movement path. The slider 9 is embedded in the arc-shaped inner guide frame 3. Under the combination of the two modes of driving and limiting, the camera 10 can achieve the left and right rotation movement above the goods.
[0038] The sorting robotic arm is connected to camera 10, motor 8 and motor 12 via a controller and corresponding control system.
[0039] Since the No. 2 motor 12 is fixedly mounted on the bracket 6 and rotates slightly on the base frame 1 and the ground along with the bracket 6, the power cord of the No. 2 motor 12 should be of appropriate length and sufficient space should be reserved for it next to the transmission mechanism.
[0040] In the cargo sorting system equipped with this device, the operating logic is as follows: the cargo is placed on the conveyor belt and moves towards the end. It first passes under the camera 10. With the support of the horizontal and vertical capture mechanisms, the camera 10 scans the information attached to the cargo and classifies and identifies it through relevant equipment. The signal is then transmitted to the robotic arm behind it. When the cargo arrives in the robotic arm's control area, the corresponding sorting operation is performed, which is completed by the relevant control system and its controller.
[0041] In a specific implementation of this invention, goods with classification information labels are transported by a conveyor belt to a location below camera 10. Motor 8 and motor 12 are started and work together to make camera 10 rotate back and forth and left and right above the goods, covering the top, front, back, left and right sides of the goods to search for the labels from all angles. After the information is detected, the goods can be sorted by a robotic arm.
[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
