Description

Technical Field

[0001] This application relates to the technical field of pen tip processing, and in particular to a testing device for pen tip processing. Background Technology

[0002] Ballpoint pens typically consist of a refill and a barrel containing the refill for easy grip. After the refill is manufactured and before it is packaged and stored, the writing smoothness of the refill needs to be tested. Writing smoothness refers to the combined effect of fluency and lubrication during writing. Writing smoothness can be quantitatively determined by using a proprietary pen refill line tester under specified writing angles, writing speeds, and writing pressures. This test measures the continuity of the writing line trajectory, the amount of ink dispensed, and its fluctuations.

[0003] The utility model patent with authorization publication number CN207439449U discloses a fully automatic pen refill marking detection machine, including: a control system; a lifting component; a clamping component fixedly connected to the lifting component; a marking paper guide component stacked on the lifting component; and a cam lifting component located below the lifting component and the clamping component, wherein the front end of the marking paper guide component is also fixedly connected to a shooting detection component.

[0004] When using the imaging and detection component, the lens surface is prone to dust accumulation. Dust on the lens surface will affect the clarity of the paper image, which in turn will affect the computer's judgment of the lines on the paper, easily leading to misjudgment and affecting the detection quality. Summary of the Invention

[0005] To improve the quality of testing, this application provides a testing device for pen tip processing.

[0006] The technical solution of the pen tip processing detection device provided in this application is as follows: A pen tip processing detection device includes a paper feeder, a guide plate, a lens holder, a camera, a wiping rod, and a wiping cloth. The guide plate is fixedly connected to the paper feeder and is used for paper to slide and adhere. The lens holder is fixedly connected to the paper feeder and the camera is fixedly connected to the lens holder and is used to photograph the paper on the guide plate. The wiping rod is slidably connected to the lens holder, and the wiping cloth is fixedly connected to the end of the wiping rod facing the camera lens and is used to wipe the camera lens.

[0007] By adopting the above technical solution, the wiping rod slides so that the wiping cloth wipes the camera lens, making the camera take clear pictures. This facilitates machine learning comparison of the pictures by the computer, reduces misjudgments, and improves the detection quality.

[0008] Preferably, the lens holder has a mounting groove on the side facing the guide plate, the camera is fixedly embedded in the mounting groove, and the two ends of the wiping rod are slidably connected to the groove wall of the mounting groove.

[0009] By adopting the above technical solution, the mounting groove guides the sliding of the wiping rod, allowing the wiping cloth to thoroughly wipe the camera lens, maintaining the clarity of the camera lens and improving the detection quality.

[0010] Preferably, a pen tip processing detection device further includes a sliding rod and a first spring. The groove wall of the mounting groove is provided with a guide groove. The end of the sliding rod is slidably embedded in the guide groove. One end of the first spring is fixedly connected to the end of the wiping rod away from the camera, and the other end of the first spring is fixedly connected to the sliding rod.

[0011] By adopting the above technical solution, the guide groove guides the sliding of the sliding rod, enabling the sliding rod to slide stably. The spring, through the wiping rod, causes the wiping cloth to press against the camera lens, facilitating the wiping of the camera lens, resulting in clearer camera images and improved detection quality.

[0012] Preferably, a pen tip processing detection device further includes a limiting rod, wherein a limiting groove is provided at one end of the wiping rod facing the sliding rod, one end of the limiting rod is fixedly connected to the end of the sliding rod facing the wiping rod, and the other end of the limiting rod is slidably connected to the groove wall of the limiting groove, and the sliding direction of the limiting rod is parallel to the axial direction of the limiting groove.

[0013] By adopting the above technical solution, the use of the limiting rod facilitates the sliding rod to slide while driving the wiping rod to move synchronously, reducing the probability of spring torsion and damage, and extending the service life of the device.

[0014] Preferably, a pen tip processing detection device further includes a reciprocating lead screw, which is rotatably connected to the wall of the guide groove about its own axis. The rotation axis of the reciprocating lead screw is perpendicular to the sliding direction of the sliding rod. The sliding rod is provided with a sliding port, and the reciprocating lead screw is threadedly connected to the inner wall of the sliding port.

[0015] By adopting the above technical solution, the reciprocating screw rotates, causing the sliding rod to slide back and forth, thereby achieving repeated wiping of the lens. The structure is simple, facilitates repeated wiping of the lens, and improves the wiping efficiency of the lens.

[0016] Preferably, a pen tip processing detection device further includes a fixed base, a fixed plate, a vibration component, and a clamping component. The upper end of the fixed base is connected to a rotating ring. A rotating rod is fixedly connected to the outer wall of the fixed plate. The rotating rod is coaxially rotatably connected to the inner wall of the rotating ring. The rotating rod is connected to a reciprocating lead screw through a transmission component. The vibration component is connected to the upper end of the fixed plate. The clamping component is connected to the upper end of the vibration component. The clamping component is used to clamp the pen tip. The vibration component is used to drive the pen tip to draw circles on the paper. The rotation of the fixed plate is used to control the pen tip to be perpendicular to the paper.

[0017] By adopting the above technical solution, the rotation of the fixed plate makes the pen refill perpendicular to the paper. At the same time, the rotation of the fixed plate drives the reciprocating screw to rotate through the transmission component, so that the wiping rod slides to wipe the camera lens. No additional drive source is required, the structure is simple, the clamping component clamps the pen refill, and the vibration component vibrates to make the pen refill draw circles on the paper, which is convenient for detecting the quality of the pen refill.

The first synchronous pulley is coaxially and fixedly connected to the outer wall of the rotating rod, the second synchronous pulley is coaxially and fixedly connected to the outer wall of the reciprocating lead screw, and the synchronous belt is sleeved on the outer periphery of the first and second synchronous pulleys.

[0019] By adopting the above technical solution, the timing pulley and timing belt are used together, the transmission component has a simple structure, is easy to use, is stable in use, and is easy to maintain and replace.

[0020] Preferably, the fixed plate is provided with a movable groove, the length direction of which is parallel to the rotation axis of the fixed plate. The vibration assembly includes a vibrating plate, a second spring, and a vibration motor. The lower end of the vibrating plate is connected to a vibrating column. The second spring is sleeved on the outer periphery of the vibrating column. The vibrating column passes through the movable groove. One end of the second spring is connected to the upper end of the fixed plate, and the other end of the second spring is connected to the lower end of the vibrating plate. The vibration motor is fixedly connected to the lower end of the vibrating plate, and the clamping assembly is fixedly connected to the upper end of the vibrating plate.

[0021] By adopting the above technical solution, the vibration motor drives the vibration plate and clamping assembly to vibrate, causing the pen tip clamped by the clamping assembly to draw circles on the paper, which facilitates the detection of the writing smoothness of the pen tip.

The guide post is fixedly connected to the upper end of the vibrating plate, the upper clamping plate is fixedly connected to the upper end of the guide post, and the lower clamping plate is slidably connected to the guide post. The sliding direction of the lower clamping plate is parallel to the axis of the guide post. The lower end of the upper clamping plate is provided with an upper clamping groove, and the upper end of the lower clamping plate is provided with a lower clamping groove. Both the upper and lower clamping grooves are used for inserting pen refills.

[0023] By adopting the above technical solution, the upper clamping groove and the lower clamping groove position the pen refill. The lower clamping plate slides upward and works together with the upper clamping plate to clamp the pen refill, so that when the fixing plate is tilted, the pen refill is less likely to fall off the detection device due to gravity, thus improving the stability of the detection.

[0024] Preferably, the clamping assembly further includes a gear, a first rack, a push plate, and a second rack. The gear is located on the side of the pen refill away from the guide plate. The gear is rotatably connected to the upper clamping plate around its own axis. The rotation axis of the gear is parallel to the rotation axis of the fixed plate. The first rack is fixedly connected to the lower clamping plate and meshes with the end of the gear away from the guide plate. The push plate is slidably connected to the upper clamping plate. The end of the push plate facing the guide plate is used to abut the tail of the pen refill. The second rack is fixedly connected to the push plate and meshes with the upper end of the gear.

[0025] By adopting the above technical solution, the lower clamping plate slides upward while driving the first rack to slide, causing the gear to rotate. The second rack slides, driving the push plate to slide. The push plate slides and pushes the pen refill against the guide plate, making it easier for the pen refill to draw circles on the paper.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The wiping rod slides so that the wiping cloth wipes the camera lens, making the camera take clear pictures, which makes it easier for the computer to perform machine learning comparison on the pictures, reducing false judgments and improving detection quality; 2. The rotation of the fixed plate makes the pen refill perpendicular to the paper. At the same time, the rotation of the fixed plate drives the reciprocating screw to rotate through the transmission component, so that the wiping rod slides to wipe the camera lens. No additional drive source is required, the structure is simple, the clamping component clamps the pen refill, and the vibration component vibrates to make the pen refill draw circles on the paper, which is convenient for detecting the quality of the pen refill. 3. As the lower clamping plate slides upward, it drives the first rack to slide, causing the gear to rotate. The second rack slides, driving the push plate to slide. The push plate slides and presses the pen refill against the guide plate, making it easier for the pen refill to draw circles on the paper. Attached Figure Description
