Description

Technical Field

[0001] This utility model relates to the field of machine vision automation equipment, and in particular to a spherical rolling body feeding device. Background Technology

[0002] In the automated inspection process of machine vision, for the appearance inspection of spherical rolling bodies, such as steel balls for bearings, ceramic balls, and cigarette bouncy balls, it is necessary to feed the spherical rolling bodies to various holes on the conveyor plate so that they can be transported to specific locations for appearance inspection.

[0003] Existing feeding and conveying mechanisms may employ various methods. Some use suction cups to absorb spherical rolling bodies under negative pressure, then a robotic arm moves the body to a hole on the conveyor plate and releases it, allowing the spherical rolling body to fall accurately into the hole. However, this suction cup feeding mechanism requires the robotic arm to move the suction cup back and forth and feed the body individually, affecting detection efficiency. Others use a vibratory feeder to batch-feed the spherical rolling bodies. Each spherical rolling body slides along a track, and a servo motor is installed below the conveyor plate to drive it. In conjunction with sensors, the holes are positioned so that the spherical rolling bodies fall into the correct holes. This vibratory feeder feeding mechanism is more complex and cannot remove multiple stacked spherical rolling bodies, affecting detection quality. Utility Model Content

[0021] Referring to the accompanying drawings, the foregoing and other features of this utility model will become apparent from the following description. Specific embodiments of this utility model are specifically disclosed in the description and drawings, illustrating some implementations in which the principles of this utility model can be adopted. It should be understood that this utility model is not limited to the described embodiments.

[0022] This utility model provides a spherical rolling body feeding device. Figure 1 This is a three-dimensional structural diagram of the assembly environment of the spherical rolling body feeding device of this utility model. As shown in the figure, the device includes a discharge port 1, a limiting frame 2, and a scraper 3. The discharge port 1 is located above the limiting frame 2 so that each spherical rolling body falls into the limiting frame 2. The limiting frame 2 is located above the area where each discharge hole is set on the conveyor plate 4 (one discharge hole 401 is marked in the example in the figure) to limit the feeding area of ​​the spherical rolling bodies. The scraper 3 is vertically set inside the limiting frame 2. Thus, each spherical rolling body is freely dropped in batches from the previous process onto the conveyor plate 4 through the discharge port 1 and is limited by the limiting frame 2 to the feeding area where each discharge hole is set. The conveyor plate 4 is driven to rotate clockwise, and the vertically set scraper 3 pushes each spherical rolling body into each discharge hole so that it can be transported to a specific position for appearance inspection as the conveyor plate 4 rotates.

[0023] Figure 2 This is a schematic diagram showing a spherical rolling element getting stuck in the material discharge hole of the conveyor plate. Figure 3 yes Figure 2 Schematic diagram of force analysis corresponding to various jamming conditions of spherical rolling elements; such as Figure 2-3 As shown, after a batch of spherical rolling bodies to be tested falls into the material limiting frame 2, various situations may occur where they stack and jam within the material dropping hole. Because the force direction of each spherical rolling body is different under different jamming conditions, in order to better remove the stacked spherical rolling bodies, according to the preferred embodiment of this utility model, see... Figure 4The scraper 3 is positioned at a first bending angle within the material limiting frame 2, near the material discharge port 1. Specifically, both sides 21 and 22 of the material limiting frame 2 have slots, and the two ends of the scraper 3 are vertically inserted into these slots. The final bending angle of the scraper 3 is controlled by the position of the slots on the two sides. Furthermore, scrapers 5, 6, and 7 are also vertically positioned within the material limiting frame 2. Scrapers 5, 6, and 7 are sequentially positioned at second, third, and fourth bending angles, respectively, on the side of the material limiting frame 2 away from the material discharge port 1. The different bending angles are designed to accommodate various stress conditions under different material stacking scenarios. By using scrapers with different bending angles, spherical rolling bodies stacked at different angles are effectively removed, preventing subsequent scratches on the conveyor tray 4.

[0024] Preferably, see Figure 1 The limiting frame 2 has a scraper recycling hopper 8 on the side away from the material discharge port 1. The recycling hopper 8 is located on one side of each scraper and is used to collect the stacked material rejected by each scraper. The scraper recycling hopper 8 is connected to the inner cavity of the limiting frame 2 through an opening 801. The opening 801 is located on one side of the area where each scraper is located. The upper surface of the opening 801 is lower than the horizontal plane of the conveyor plate 4. The stacked spherical rolling bodies that are rejected roll into the opening 801 and enter the scraper recycling hopper 8.

[0025] According to a preferred embodiment of this utility model, the material limiting frame 2 has an opening below the side frame 23 near the material discharge port 1. Furthermore, a baffle 9 is provided on the side of the side frame 23 near the material discharge port 1. Specifically, a pair of slots are formed at the ends of the frame 21 and frame 22 of the material limiting frame 2, and the baffle 9 is inserted into the slots to close the opening below the frame 23. When equipment debugging or changeover testing requires material clearing, the baffle 9 is first pulled upwards to expose the opening. The unfinished spherical rolling bodies to be tested within the material limiting frame 2 roll out from the notch and are cleared. Then, the baffle 9 is closed for subsequent operations.

[0026] According to a preferred embodiment of the present invention, a sensor 10 is provided between the material discharge port 1 and the scraper 3 to monitor the feeding and jamming of each spherical rolling body to be detected in the limiting frame 2.

[0027] Preferred embodiments of the present invention have been described above with reference to the accompanying drawings, and many features and advantages of these embodiments become apparent from this detailed description. Furthermore, since many modifications and alterations will readily occur to those skilled in the art, the embodiments of the present invention are not intended to be limited to the precise structures and operations illustrated and described.
