Description

Technical Field

[0001] This utility model relates to the field of ball detection technology, and in particular to a ball detection device. Background Technology

[0002] Ballpoint pens are widely used as everyday writing tools, and the quality of their nibs directly affects the smoothness of writing. During the production process, the balls used in the nibs may have various defects such as uneven roundness, dents, and scratches. Therefore, the balls need to be inspected after production.

[0003] A ball detection device and system with patent number CN206997115U uses a rotating turntable to transport and detect balls. However, during the feeding process, the feeding mechanism may fail to feed the balls, leaving the material receiving slot on the turntable empty. In the preset operating program, the turntable will rotate intermittently at a preset angle regardless of whether there is material in the material receiving slot, so as to rotate the material receiving slot to the underside of the visual recognition device for visual recognition detection. If the feeding mechanism frequently fails to feed the balls (due to abnormalities), the time it takes for subsequent balls to rotate to the underside of the visual recognition device will increase, which will increase the overall detection time and make it difficult to detect subsequent balls at the same rate, thus reducing the detection efficiency.

[0004] Therefore, it is necessary to propose a ball detection device to avoid increasing the detection time of subsequent balls when there is a missing ball, thereby maintaining detection efficiency. Utility Model Content

[0011] Furthermore, the material mixing turntable is provided with a conical mixing end for mixing the ball.

[0012] Furthermore, the rotating material transfer device includes a driving device, a material feeding disc, and a fixed frame. The driving device is electrically connected to the controller.

[0017] The beneficial effects of this utility model are:

[0018] This invention employs a material height detection device to detect the height of the material on the rotating material transfer device before visual inspection. During visual inspection, since the material height detection device maintains a first distance from adjacent visual inspection devices, once the material height detection device detects that there is no material in the material area below, the area without material can be rapidly rotated by the rotating material transfer device, thus quickly passing under the visual inspection device and avoiding lengthening the inspection time of subsequent beads. In summary, this bead detection device can effectively avoid increasing the inspection time of subsequent beads when there is no material falling, thereby maintaining inspection efficiency.

[0035] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0036] Please refer to Figures 1-7This utility model proposes a ball detection device, including a frame 1, a controller 2, a stirring and discharging device 3, a material height detection device 4, a rotating and transferring device 5, at least one vision detection device 6, and a material blowing mechanism 7. The stirring and discharging device 3, the rotating and transferring device 5, the material height detection device 4, the at least one vision detection device 6, and the material blowing mechanism 7 are all fixedly connected to the frame 1. The material blowing mechanism 7, the stirring and discharging device 3, the material height detection device 4, and the at least one vision detection device 6 are arranged in an arc along the rotation direction of the rotating and transferring device 5. The material height detection device 4 maintains a first distance from the adjacent vision detection device 6. One end of the stirring and discharging device 3, one end of the vision detection device 6, and one end of the material blowing mechanism 7 all extend to the upper outer periphery of the rotating and transferring device 5. The controller 2 is electrically connected to the stirring and discharging device 3, the rotating and transferring device 5, the material height detection device 4, the vision detection device 6, and the material blowing mechanism 7 respectively. The vision detection device 6 is a CCD camera, which can perform CCD detection on the material. The number of vision detection devices 6 can be one or more, arranged according to requirements.

[0037] In this embodiment, the material height detection device 4 detects the height of the material on the rotating material transfer device 5 before visual inspection. During visual inspection, the stirring and discharging device 3 drops the beads one by one onto the rotating material transfer device 5. The rotating material transfer device 5 pauses intermittently to catch the beads, ensuring that the beads 8 are evenly distributed. If the stirring and discharging device 3 misses a drop, an empty space will appear in the material area on the rotating material transfer device 5 where the beads were originally, and the height detected by the visual inspection device 6 when the rotating material transfer device 5 is paused will decrease. Since the rotating material transfer device 5 rotates from left to right, and the material height detection device 4 is adjacent to the visual inspection device... 6. Maintain a first spacing (the first spacing is 2 to 4 bead positions between the bead detected by the material height detection device 4 and the bead detected by the adjacent vision detection device 6; the first spacing can be adjusted as needed). The distance between the material height detection device 4 and the mixing and discharging device 3 is not limited and can be adjusted as needed. After the material height detection device 4 detects that there is no material in the material area below, taking a first spacing of 4 bead positions as an example, when the vision detection device 6 detects that there is a lack of material below, the rotating transfer device 5 will rotate continuously for the fourth material area after three intermittent pauses in detecting the beads. That is, the area without material is rotated by the rotating device 5. The material transfer device 5 rotates rapidly, quickly passing under the vision inspection device 6. It stops under the vision inspection device 6 again in the fifth material area. If the vision inspection device 6 detects a lack of material below and also a lack of material in the next material area, the material transfer device 5 will rotate intermittently for three pauses to inspect the beads. In the fourth and fifth material areas, it will stop without stopping, stopping under the vision inspection device 6 again in the sixth material area, and so on, to avoid lengthening the inspection time for subsequent beads. Furthermore, to prevent the beads dropped by the mixing and discharging device 3 from skipping over equally spaced material areas while the material area is rapidly passing under the vision inspection device 6, the material transfer device 5 will rotate continuously. In cases where acceleration occurs frequently due to the area, after the mixing and discharging device 3 has failed to discharge material once (i.e., after the material height detection device 4 detects that there is no material in the material area below), the mixing and discharging device 3 will stop discharging material. The controller 2 records the number of times material falls without material. If the number of times material falls without material exceeds a preset number, the device will stop operating and sound a fault alarm. After all the balls on the rotating material transfer device 5 have been detected and discharged from the rotating material transfer device 5, the rotating material transfer device 5 will reset, and the mixing and discharging device 3 will start discharging material again from the starting point of the rotating material transfer device 5. This ensures that the detection of material (balls) is continuous and the time is constant.

[0038] The controller 2 includes a data processing module 21, a first drive module 22, a distance detection module 23, a second drive module 24, a third drive module 25, and a storage module 26. The data processing module 21 is electrically connected to the first drive module 22, the distance detection module 23, the second drive module 24, the third drive module 25, the storage module 26, and the vision detection device 6. The data processing module 21 is used to issue corresponding operating instructions to the first drive module 22, the second drive module 24, and the third drive module 25, and to receive height data from the distance detection module 23 and image data from the vision detection device 6, and to compare the height data and image data respectively. At the same time, it calls the stored data in the storage module 26. The first drive module 22 is electrically connected to the mixing and discharging device 3 and is used to issue a first operating instruction to the mixing and discharging device 3, so that the mixing and discharging device 3... Material feeding device 3 feeds material; distance detection module 23 is electrically connected to material height detection device 4. Distance detection module 23 receives height data detected by material height detection device 4 and transmits it back to data processing module 21. Data processing module 21 compares the transmitted height data with the pre-stored height data to determine whether there is material below; second drive module 24 is electrically connected to rotating material transfer device 5. Second drive module 24 issues second running commands to rotating material transfer device 5, causing rotating material transfer device 5 to rotate at constant or variable speed; third drive module 25 is electrically connected to material blowing mechanism 7. Third drive module 25 issues third running commands to material blowing mechanism 7, causing material blowing mechanism 7 to be driven or shut down; storage module 26 stores the number of times material falls without being fed, the location of good material, and the location of defective material.

[0039] In summary, this ball detection equipment can effectively avoid increasing the detection time of subsequent balls when there is a missing ball, thereby maintaining detection efficiency.

[0040] In this embodiment, the material height detection device 4 includes a vertical frame 41, an adjusting frame 42, a knob adjusting component 43, and an infrared distance sensor 44. The infrared distance sensor 44 is electrically connected to the controller 2. One end of the vertical frame 41 is fixedly connected to the frame 1 and located on one side of the rotating material transfer device 5. One end of the adjusting frame 42 is slidably adjusted to the other end of the vertical frame 41. One end of the knob adjusting component 43 is threadedly connected to the adjusting frame 42 and abuts against the surface of the vertical frame 41. The infrared distance sensor 44 is fixedly connected to the other end of the adjusting frame 42 and faces vertically toward the upper outer peripheral surface of the rotating material transfer device 5. The infrared distance sensor 44 can adjust the height of the rotating material transfer device 5 by adjusting the up and down sliding position of the adjusting frame 42 to adjust the appropriate installation height. After adjustment, the adjusting frame 42 is fixed by tightening the knob adjusting component 43, which is convenient and quick.

[0041] In this embodiment, the mixing and discharging device 3 includes a support frame 31, a storage hopper 32, a motor 33, a distributing mixing turntable 34, and a discharge pipe 35. The motor 33 is electrically connected to the controller 2. One end of the support frame 31 is fixedly connected to the frame 1 and located on one side of the rotating material transfer device 5. The motor 33 is fixedly connected to the support frame 31. The storage hopper 32 is fixedly connected to the other end of the support frame 31. One end of the distributing mixing turntable 34 is fixedly connected to the rotating shaft of the motor 33 at its center. The other end of the distributing mixing turntable 34 extends into the storage hopper 32 and communicates with the storage hopper 32. One side of the discharge pipe 35 is fixedly connected to the support frame 31, and one end of the discharge pipe 35 is connected to the storage hopper 32. The material is connected to one side of the lower surface of the material mixing turntable 34, and the other end of the discharge pipe 35 extends to the upper outer periphery of the rotating material transfer device 5. When the material is discharged, since the material is in the form of spheres, a large number of spheres remain in the storage hopper 32. The spheres exert pressure on each other, resulting in greater resistance to falling. In order to ensure that spheres fall every time the rotating material transfer device 5 is paused, the motor 33 drives the material mixing turntable 34 to mix the spheres inside the storage hopper 32, so that the spheres roll into the material mixing turntable 34 and then fall one by one into the discharge pipe 35, and then into the material area of ​​the rotating material transfer device 5 through the discharge pipe 35.

[0042] In this embodiment, the distributing and mixing turntable 34 is provided with multiple pre-drop grooves 341, which are evenly distributed around the circumference. One of the pre-drop grooves 341 is connected to one end of the discharge pipe 35. The function of the multiple pre-drop grooves 341 is to allow the balls to fall into the pre-drop grooves 341 first when the distributing and mixing turntable 34 rotates and mixes. Since the pre-drop grooves 341 are connected grooves, after the balls fall in, only one pre-drop groove 341 is connected to one end of the discharge pipe 35, while the rest of the pre-drop grooves 341 are blocked by the bottom wall of the storage hopper 32. This ensures that most of the pre-drop grooves 341 can contain balls. When the distributing and mixing turntable 34 rotates, the pre-drop grooves 341 containing balls align with one end of the discharge pipe 35, and the balls will fall down the discharge pipe 35 into the material area of ​​the rotating material transfer device 5.

[0043] In this embodiment, the material mixing turntable 34 is provided with a conical mixing end 342 for mixing the beads. When the material mixing turntable 34 rotates and mixes, the conical mixing end 342 rotates and mixes against the bottom of a pile of beads in the storage hopper 32, so that the beads roll down the slope of the conical mixing end 342. When the material mixing turntable 34 rotates, most of the beads can enter the pre-falling groove 341.

[0044] In this embodiment, the rotating material transfer device 5 includes a drive device 51, a material feeding disc 52, and a fixed frame 53. The drive device 51 is electrically connected to the controller 2. One end of the drive device 51 is fixedly connected to the fixed frame 53, and one end of the fixed frame 53 is fixedly connected to the frame 1. The center of the material feeding disc 52 is fixedly connected to the output end of the drive device 51. The material feeding disc 52 is located on the upper surface of the fixed frame 53 and is rotatably connected to the fixed frame 53. The drive device 51 is a direct drive motor (DD motor). When feeding material, the drive device 51 drives the material feeding disc 52 to rotate intermittently, so as to push the material to move in an arc on the surface of the fixed frame 53, and then move it to the area below the vision inspection device 6 for inspection.

[0045] In this embodiment, a grooved feeding ring 521 is provided on the outer periphery of the feeding disc 52, and a material support groove 531 is provided on the outer periphery of the fixing frame 53. The material support groove 531 is a circular structure arranged around the outer periphery of the fixing frame 53. The grooved feeding ring 521 is located above the material support groove 531. One end of the stirring and discharging device 3, one end of the visual inspection device 6, and one end of the material blowing mechanism 7 all extend above the grooved feeding ring 521. When the ball falls from the discharging pipe 35, the bottom of the ball will be supported by the material support groove 531. When the feeding disc 52 rotates, the grooved feeding ring 521 will push the ball to roll along the direction of the material support groove 531.

[0046] In this embodiment, the inter-slot feeding ring 521 is provided with a plurality of U-shaped grooves 5211, which are evenly distributed around the inter-slot feeding ring 521. All of the U-shaped grooves 5211 are connected to the material support groove 531. When the ball falls from the drop tube 35, the ball will fall into the U-shaped groove 5211 aligned with the drop tube 35, and most of the ball will be contained in the U-shaped groove 5211. When the feeding disc 52 rotates, the groove wall of the U-shaped groove 5211 will push the ball to roll along the direction of the material support groove 531.

[0047] In this embodiment, the U-shaped groove 5211 is perpendicular to the material support groove 531 so that when the feeding disc 52 rotates, the groove wall of the U-shaped groove 5211 applies a pushing force to the ball.

[0048] In this embodiment, the material blowing mechanism 7 includes an arc-shaped mounting frame 71, multiple blowing nozzles 72, and multiple material dropping channels 73. All blowing nozzles 72 are electrically connected to the controller 2 and to an external air pipe. The blowing nozzles 72 are opened or closed by a solenoid valve, which is electrically connected to the controller 2. The external air pipe is always in a state of continuous air supply. When it needs to be opened, the solenoid valve is energized and opens, allowing gas to flow into the blowing nozzles 72, causing them to blow air. When it needs to be closed, the solenoid valve is de-energized and closes, leaving the blowing nozzles 72 without air. The material is ejected from the arc-shaped mounting bracket 71, which is fixedly connected to the frame 1 and located on one side of the rotating material transfer device 5. Multiple air nozzles 72 and multiple material drop channels 73 are fixedly connected to the arc-shaped mounting bracket 71. One end of each air nozzle 72 extends above one side of the rotating material transfer device 5 and corresponds to one of the multiple material drop channels 73, facing the groove feeding ring 521 and the material drop channels 73. The multiple material drop channels 73 can be divided into two parts: one for good products and another for defective products. For example, there may be 10 material drop channels. Channel 73 can divide the 10 feeding channels 73 into 7 feeding channels for good products and 3 feeding channels for defective products. After the vision inspection device 6 inspects the balls below, it will mark the balls of good and defective products and record their positions. For example, there are 50 U-shaped grooves 5211, each containing one ball. The arc distance between the vision inspection device 6 and the feeding channel for good products is 30 ball intervals, and the arc distance between the vision inspection device 6 and the feeding channel for defective products is 37 ball intervals. After the visual inspection device 6 marks the lower ball as a good product, the material feeding plate 52 rotates intermittently for 30 times, and the good ball will align with the good product drop channel. At this time, the corresponding blower nozzle 72 will be turned on, and the good ball will be blown into the good product drop channel. After the visual inspection device 6 marks the lower ball as a defective product, the material feeding plate 52 rotates intermittently for 37 times, and the defective ball will align with the defective product drop channel. At this time, the corresponding blower nozzle 72 will be turned on, and the defective ball will be blown into the defective product drop channel.

[0049] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
