Description

Technical Field

[0001] This utility model relates to the field of quality inspection technology, and in particular to a ballpoint pen tip testing 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, ballpoint pen nibs may have various defects such as missing balls, uneven wear, and clogged ink outlets. Therefore, after the ballpoint pens are produced, they need to be inspected, and a vibratory feeder is required for feeding during the inspection.

[0003] Nowadays, most testing equipment uses CCD to inspect components. However, CCD inspection requires the materials to be aligned with uniform edges so that the material edges are always in a fixed area in the image. For devices that use conveyor belts for transportation, it is difficult to align the materials. During the inspection process, a robotic arm is needed to move the materials to a positioning platform for inspection, which adds time to the moving process.

[0004] The pen tip testing device with patent number CN208350033U uses a rotary CCD detection method to observe and test each pen tip individually, which is inefficient and occupies a large space.

[0005] Therefore, it is necessary to propose a ballpoint pen tip detection device to solve the problem of pen tips being difficult to align during transportation using a conveyor belt, thereby facilitating rapid CCD detection and improving detection efficiency. Utility Model Content

[0033] 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.

[0034] Please refer to Figures 1-6This utility model proposes a ballpoint pen tip detection device, including a conveying device 1, a sweeping device 2, a first identification camera assembly 3, a second identification camera assembly 4, and a controller 5. The sweeping device 2, the first identification camera assembly 3, and the second identification camera assembly 4 are all fixedly connected to the conveying device 1. The conveying device 1 is inclined. In order to more effectively align the pen tip to one side under the action of gravity, the angle between the conveying device 1 and the horizontal plane needs to be 20 to 35 degrees. The conveying direction of the conveying device 1 can be inclined upward or inclined downward. The sweeping device 2 is located above the conveying device 1 and contacts the upper surface of the conveying device 1. The first identification camera assembly 3 is located on one side of the conveying device 1 and faces the upper surface of the conveying device 1. The second identification camera assembly 4 is located above one end of the conveying device 1 and faces downward towards the upper surface of the conveying device 1. The controller 5 is electrically connected to the conveying device 1, the sweeping device 2, the first identification camera assembly 3, and the second identification camera assembly 4 respectively. The first identification camera assembly 3 and the second identification camera assembly 4 both use MER2-G series products.

[0035] In this embodiment, the controller 5 issues operating commands to the conveying device 1, the sweeping device 2, the first recognition camera assembly 3, the second recognition camera assembly 4, and the robotic arm. The robotic arm transports the pen tips one by one to the starting end of the conveying device 1 for placement. The starting end of the conveying device 1 is the end away from the second recognition camera assembly 4. The surface of the conveying device 1 has spaced placement slots, in which the pen tips can be placed for transport. The conveying device 1 transports the pen tips in batches at intervals, and the conveying device 1 is tilted so that each pen tip automatically moves towards the side of gravity during transport, solving the alignment problem in the X-axis direction. During transport, the sweeping device 2 sweeps the pen tips in the Y-axis direction, so that one end of the pen tip moves towards the Y-axis direction, solving the alignment problem in the Y-axis direction. The X-axis direction and the Y-axis direction are perpendicular to each other. Then, the pen tips are sequentially detected by the first recognition camera assembly 3 and the second recognition camera assembly 4 using CCD. This completes the detection of each pen tip in the same batch without the need for a separate robotic arm to transport the pen tips to the detection area, making it convenient and fast.

[0036] In summary, this ballpoint pen tip detection equipment can effectively solve the problem of pen tips being difficult to align during transport using a conveyor belt, thereby facilitating rapid CCD detection and improving detection efficiency.

[0037] In this embodiment, the conveying device 1 includes a drive device 11, a driving roller 12, a driven roller 13, a positioning conveyor belt assembly 14, and a support frame 15. The drive device 11 is a stepper motor used to drive the driving roller 12 to rotate. The driving roller 12 and the driven roller 13 are rotatably connected to both ends of the support frame 15, respectively. The driving roller 12 and the driven roller 13 are respectively connected to the inner ends of the positioning conveyor belt assembly 14. A portion of the support frame 15 is located inside the positioning conveyor belt assembly 14. The device also includes a sweeping device 2, a first identification camera assembly 3, and a second... The identification camera assembly 4 is fixedly connected to the support frame 15. The rotating shaft of the drive device 11 is fixedly connected to the center of the active roller 12. The drive device 11 is electrically connected to the controller 5. When the conveying device 1 is in operation, the drive device 11 drives the active roller 12 to rotate. The support frame 15 supports the rotation of the active roller 12 and the driven roller 13. With the support of the driven roller 13, the positioning conveyor belt assembly 14 is transported. A part of the support frame 15 is located inside the positioning conveyor belt assembly 14, which saves installation space and reduces the external space occupied.

[0038] In this embodiment, the positioning conveyor belt assembly 14 includes a conveyor belt 141 and a plurality of positioning transport blocks 142. The conveyor belt 141 is provided with mounting bosses 1411 in the same number as the positioning transport blocks 142. The plurality of mounting bosses 1411 are arranged sequentially at equal intervals. The plurality of positioning transport blocks 142 correspond one-to-one with the plurality of mounting bosses 1411 and are fixedly connected. The upper surface of the positioning transport blocks 142 extends to the bottom of the sweeping device 2. When the conveyor belt 141 is straight, the plurality of positioning transport blocks 142 are arranged end to end. The positioning transport blocks 142 are used to carry the pen tip. When the driving device 11 rotates and drives the conveyor belt 141 to transport the pen tip, the plurality of positioning transport blocks 142 are driven by the conveyor belt 141 to transport the pen tip in sequence towards the second recognition camera assembly 4.

[0039] In this embodiment, the positioning transport block 142 is provided with a placement boss 1421, which extends to the bottom of the sweeping device 2. When multiple positioning transport blocks 142 move sequentially at the bottom of the sweeping device 2, the placement boss 1421 moves against the inner wall of the bottom of the sweeping device 2, so that the rotating sweeping head 23 of the sweeping device 2 can sweep the pen tip on the placement boss 1421, so that one end of the pen tip moves toward the side wall in the direction of rotation of the rotating sweeping head 23, that is, neatly moves toward the Y-axis.

[0040] In this embodiment, the placement boss 1421 is provided with a plurality of placement slots 14211, which are arranged in sequence. The diameter of the placement slots 14211 is slightly larger than the diameter of the pen tip. After the pen tip is placed in the placement slot 14211, the pen tip automatically moves toward the side of gravity during transportation, that is, it automatically moves toward one side wall of the placement slot 14211, thus solving the alignment problem in the X-axis direction.

[0041] In this embodiment, the sweeping device 2 includes a fixed frame 21, a motor 22, and a rotating sweeping head 23. The motor 22 is a DC geared motor and is electrically connected to a controller 5. The controller 5 can control the rotation speed of the motor 22. The two sides of the fixed frame 21 are fixedly connected to the support frame 15. The bottom of the fixed frame 21 is provided with a relief groove 211, and the placement boss 1421 is received in the relief groove 211. When the placement boss 1421 moves, it moves along the direction of the relief groove 211. Under the restriction of the groove wall of the relief groove 211, the pen tip will not accidentally detach from the placement groove 14211. The motor 22 is fixedly connected to the top of the fixed frame 21. One end of the rotating sweeping head 23 is rotatably connected to the top of the fixed frame 21, and the other end of the rotating sweeping head 23 is connected to the top of the fixed frame 21. The rotating head 23 is fixedly connected to the shaft of the motor 22, and one side of the rotating head 23 contacts the placement boss 1421. The rotating head 23 has a cylindrical structure. When the motor 22 rotates, the motor 22 drives the rotating head 23 to sweep the pen tips in the multiple placement slots 14211 in the Y-axis direction. The Y-axis direction is exactly the direction of one side wall of the avoidance slot 211. One side wall of the avoidance slot 211 is a smooth plane, so that the pen tips are neatly aligned in the Y-axis direction, that is, they are aligned in the side wall of the avoidance slot 211. After the placement boss 1421 moves out of the avoidance slot 211, the pen tips will not have any displacement in the Y-axis direction. That is, the pen tips are all successfully positioned at this time, so as to facilitate the subsequent CCD detection by the first recognition camera component 3 and the second recognition camera component 4.

[0042] In this embodiment, the first recognition camera assembly 3 includes a first mounting bracket 31, a first supplementary light 32, and a first visual recognition camera 33. One end of the first mounting bracket 31 is slidably and adjustablely fixedly connected to the support frame 15. The first supplementary light 32 and the first visual recognition camera 33 are both fixedly connected to the other end of the first mounting bracket 31. The first supplementary light 32 is located on one side of the upper surface of the positioning conveyor belt assembly 142 and in front of the first visual recognition camera 3. The first visual recognition camera 3 faces the upper surface of the positioning conveyor belt assembly 142. The first supplementary light 32 and the first visual recognition camera 33 are both electrically connected to the controller 5. Before the first CCD detection, the first mounting bracket 31 can be laterally adjusted in position on the support frame 15. The pen tip is adjusted to the optimal detection position. During the first CCD inspection, the first supplementary light 32 is turned on. After the pen tip is transported to a position aligned with the first visual recognition camera 33, the drive device 11 pauses, the conveyor belt 141 stops transporting, and the pen tip remains in the position aligned with the first visual recognition camera 33 for a first preset time, allowing the first visual recognition camera 33 to perform CCD inspection. After the first CCD inspection is completed, the pen tip is marked by the first visual recognition camera 33. For example, if the pen tip is a good product, the outline of the pen tip is marked in green in the image of the first visual recognition camera 33. If the pen tip is found to have dents or scratches, it is a defective product, and the pen tip is marked in green in the image of the first visual recognition camera 33. The outline is marked in red, then the drive unit 11 is activated, and the conveyor belt 141 begins to transport the signal. The second recognition camera assembly 4 includes a second mounting bracket 41, a second supplementary light 42, and a second visual recognition camera 43. One end of the second mounting bracket 41 is fixedly connected to the support frame 15. The second supplementary light 42 and the second visual recognition camera 43 are both fixedly connected to the other end of the second mounting bracket 41. The second supplementary light 42 is located above the positioning conveyor belt assembly 142 and in front of the second visual recognition camera 43. The second visual recognition camera 43 faces the upper surface of the positioning conveyor belt assembly 142 from top to bottom. Both the second supplementary light 42 and the second visual recognition camera 43 are electrically connected to the controller 5. In the second CCD detection, the second visual recognition camera... 43. Visual recognition detection is performed from top to bottom. When the good pen tip is directly below the second visual recognition camera 43, the drive device 11 pauses again, and the conveyor belt 141 stops transporting again. The pen tip stays at the position aligned with the second visual recognition camera 43 for a second preset time, allowing the second visual recognition camera 43 to perform CCD detection. After completing the second CCD detection, the pen tip will be marked by the second visual recognition camera 43. For example, if the pen tip is good in the first detection and is still good in the second detection, the outline of the pen tip will be kept in green in the image of the second visual recognition camera 43. If the pen tip is found to have dents or scratches, it is a defective product, and the outline of the pen tip will be marked in red in the image of the second visual recognition camera 43.

[0043] In this embodiment, the support frame 15 is provided with a crossbeam 151, and one end of the first mounting frame 31 is provided with a sliding groove 311 and an adjustable clamping part 312. The adjustable clamping part 312 is located on one side of the sliding groove 311, and the crossbeam 151 passes through the sliding groove 311. The adjustable clamping part 312 abuts against the crossbeam 151. When adjusting the position of the first mounting frame 31, the adjustable clamping part 312 can be released, and then the first mounting frame 31 can be slid left and right on the crossbeam 151. After the first mounting frame 31 is adjusted to a suitable position, the adjustable clamping part 312 is tightened so that the adjustable clamping part 312 abuts against one side of the crossbeam 151 to fix the first mounting frame 31.

[0044] In this embodiment, the adjustable clamping part 312 includes a fixing block 3121, a knob bolt 3122, and an abutment block 3123. The abutment block 3123 is slidably connected to one side of the fixing block 3121. The abutment block 3123 is located on one side of the sliding groove 311 and faces the sliding groove 311. The knob bolt 3122 passes through the fixing block 3121 and is threadedly connected to the fixing block 3121. One end of the knob bolt 3122 is rotatably connected to one side of the abutment block 3123. When the abutment block 3123 is released, the knob bolt 3122 is rotated in the opposite direction. 2. Twist the knob bolt 3122, and the abutment block 3123 will be driven by the knob bolt 3122 to slide towards the fixing block 3121. At this time, the abutment block 3123 will release its abutment against one side of the cross frame 151, and the position of the first mounting bracket 31 can be adjusted. When it is necessary to abut the abutment block 3123 against the cross frame 151, twist the knob bolt 3122 in the forward direction, and the abutment block 3123 will be driven by the knob bolt 3122 to slide towards the cross frame 151, and finally abut against one side of the cross frame 151, fixing the first mounting bracket 31.

[0045] In this embodiment, the ballpoint pen tip detection device also includes a discharge air valve 6. The discharge air valve 6 is connected to the air supply pipe via a hose and is electrically connected to the controller 5. The discharge air valve 6 is fixedly connected to the support frame 15 and located on one side of the positioning conveyor belt assembly 14. The nozzle 61 of the discharge air valve 6 is tilted downward toward the upper surface of the positioning conveyor belt assembly 14. The discharge air valve 6 is used to blow the defective pen tip off from one side of the positioning conveyor belt assembly 14. After the first CCD detection, the outline of the defective pen tip has been marked in red and no second CCD detection is required. After the second CCD detection of the good pen tip, the outline of the defective pen tip is also marked in red. When the defective pen tip is transported to one side of the nozzle 61, the discharge air valve 6 opens to spray air, causing the defective pen tip to be blown into the defective collection box.

[0046] In this embodiment, the controller 5 includes a main control chip 51, a first drive module 52, a second drive module 53, a third drive module 54, a fourth drive module 55, and a fifth drive module 56.

At the same time, it receives image information, i.e., photos, from the first visual recognition camera 33 and the second visual recognition camera 43, and compares the photos taken on site with preset photos one by one. For example, the top view photo is compared with the preset top view photo, and the left view photo is compared with the preset left view photo. Finally, the photos that meet the preset requirements are compared. The pen tips in the top view and left view photos are considered good products, while those in photos that do not meet the requirements are considered defective.
