[0002] In intelligent assembly line operations, small parts, such as fasteners, are frequently used. Incoming small parts are transported to the workstation via storage fixtures, and then sorted one by one to the line edge. For example, a bolt-specific sorting device disclosed in patent publication number CN107486404A uses a turntable and leverages centrifugal force combined with a vibrating plate to sort the bolts. Before use, the device adjusts the distance between the sliding plate located in the groove on the connecting plate and the adjacent connecting plate according to the size of the bolts to be sorted, controlled by an adjusting disc.

[0003] However, such sorting devices are mostly used in fixed workstation operations. If they are used on a highly flexible assembly line, there will be blind spots in material conveying, and they will not be able to adapt well. Utility Model Content

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0020] like Figure 1 , Figure 2 As shown, the material shoveling device provided in this embodiment includes a bucket 1, a connecting column 2, a mounting base 3, and an adjusting mechanism 4.

[0021] The bucket 1 includes a bottom plate 11, a back plate 13, and two side plates 12. The bottom plate 11 is connected between the bottoms of the two side plates 12, the back plate 13 is connected to one end of the two side plates 12, and the other end of the two side plates 12 forms a shovel opening 16. The height of the side plates 12 gradually decreases from the back plate 13.

[0022] The connecting column 2 connects the back plate 13 and the mounting base 3. In the first embodiment, the connecting column 2 is a structural component that serves a connecting function. A weight sensor 5 is installed on the base plate 11. The weight sensor 5 is electrically connected to the control system of the robotic arm and can display the weight value on the display screen of the robotic arm. In the second embodiment, the connecting column 2 is a Guanjiang electronic digital display weighing bar with a built-in display screen, which can display the weight of the material entering the bucket 1.

[0023] The bucket 1 is equipped with an adjustment mechanism 4 for adjusting the opening of the shovel opening 16. There are two adjustment mechanisms 4 arranged symmetrically along the center line H inside the bucket 1.

[0024] The adjustment mechanism 4 includes a drive source 41 and a baffle 42. A mounting plate 14 and a guide plate 15 are provided on the inner surface of the side plate 12. The drive source 41 is mounted on the mounting plate 14 and is a servo motor with its power output end facing upwards. The guide plate 15 is located at the lower end of the mounting plate 14.

[0025] The baffle 42 includes a baffle plate 421, a first connecting rod 422 perpendicularly connected to the baffle plate 421, and a second connecting rod 423 perpendicularly connected to the first connecting rod 422. The baffle plate 421 is placed on the base plate 11 and located in front of the guide plate 15 (on the side away from the back plate 13). The end of the second connecting rod 423 away from the first connecting rod 422 is connected to the power output end of the drive source 41.

[0026] The inner surface of the guide plate 15 near the center line H forms a first guide surface 151, which causes the thickness of the guide plate 15 to gradually decrease from near the baffle 42. The inner surface of the baffle 42 near the center line H is sequentially formed with a second guide surface 4211 and a third guide surface 4212. The third guide surface 4212 is disposed near the back plate 13. The second guide surface 4211 is an arc-shaped surface, causing the thickness of the baffle 42 to gradually decrease from the third guide surface 4212.

[0027] like Figure 3 As shown, a channel for material 7 to enter and exit is formed between the two baffles 421 and the guide plate 15 that are set opposite to each other.

[0028] The drive source 41 drives the first connecting rod 422 to swing, which in turn drives the second connecting rod 423 and the baffle 421 to swing to form a first position and a second position. Figure 2 As shown, in the first position, the baffle 42 is positioned away from the center line H of the shovel opening 16, and the opening size of the shovel opening 16 is at its maximum. Figure 2 , Figure 3 As shown, in the second position, the baffle 42 is positioned close to the center line H of the shovel opening 16. The number of rotations of the servo motor can be adjusted according to the size of the material to form different second positions, adapting to the sorting of materials of different sizes.

[0029] like Figure 4 As shown, the present invention also provides a robotic arm 6, including the above-mentioned shoveling device, wherein the mounting base 3 of the shoveling device is installed at the end of the robotic arm 6.

[0030] In use, place the adjustment mechanism 4 in the first position, drive the robotic arm to the workstation where the parts are stored, and scoop in the material. Then check the weight on the display screen. Move the robotic arm to the workstation. The robotic arm can be mounted on a mobile chassis, enabling more flexible and intelligent operation. Input the designed quantity of parts for the workstation operation into the control system. The control system calculates the total weight G2 of the parts required for the workstation based on the weight G1 of a single part and the designed quantity W. Then subtract G2 from the total weight G3 currently in the bucket 1 to obtain the weight G4. Start the drive source 41 and swing the baffle 42 to a suitable second position. The suitable second position means that the space between the two baffles 42 is just enough for one material to be discharged (e.g., Figure 3 (As shown). Start the robotic arm, tilt the shovel opening 16, and swing the robotic arm appropriately to generate vibration, outputting materials one by one from the shovel opening 16. When the sensed weight of the bucket 1 equals G4, raise the robotic arm and stop discharging materials.

[0031] This invention can adapt to the sorting needs of small materials of different sizes and specifications, automatically weigh them, and has strong versatility and practicality.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
