Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] See Figure 1-2 This embodiment relates to a pen refill writing smoothness detection device, including a base 100 and a connecting assembly 3 that is slidably mounted on the base 100 via a three-axis slide module 1. A driving component 2 for rotating the connecting assembly 3 is mounted on a frame that moves along the Z-axis in the three-axis slide module 1. The connecting assembly 3 includes a fixed seat 4 connected to the driving component 2 and a connecting seat 5 rotatably mounted on the fixed seat 4. The connecting seat 5 includes a first seat 6 and a second seat 7 that rotate along the inner and outer sides of the fixed seat 4, respectively. The first seat 6 has a convex ring 51 and a locking element 52 rotatably mounted on the convex ring 51. The second seat 7 has a connecting rod 71 that passes through the first seat 6. The left and right sides of the first seat 6 and the second seat 7 are respectively provided with sliding grooves 62 and rotatably mounted second locking elements 72 at the connection positions with the fixed seat 4. The connecting rod 71 is fitted with a compression spring 74 and rotatably mounted with multiple sets of third locking elements 75. The second seat 7 also has a connecting plate 53 slidably mounted on it, and a second convex ring 531 is provided below the connecting plate 53 at the position corresponding to the convex ring 51.

[0019] Specifically in this embodiment, such as Figure 1The overall structure of this pen refill writing smoothness detection device, as shown, uses a three-axis slide module 1 on the base 100, which is conventionally designed in the prior art. Through the first drive motor 11, the second drive motor 12, and the third drive motor 13 located at different positions on its frame, combined with the driving sliding method of the synchronous belt slide 14 and the lead screw slide 15, the driving component 2 and its connecting assembly 3 can move along the X, Y, and Z axes above the base 100. Figure 2 The diagram shows the specific structural configuration of the drive component 2 and its connecting assembly 3 of the fourth drive motor 20. The fixed base 4 is installed on the drive shaft 21 of the fourth drive motor 20, enabling the drive component 2 to drive the connecting assembly 3 to rotate. The first seat 6 and the second seat 7 in the connecting base 5 can rotate at an appropriate angle on one side of the fixed base 4. In the early stage of testing, the pen refill can be inserted into the through groove 512 opened in the convex ring 51 for a certain length. The tail end of the pen refill can be placed into the groove formed by the second convex ring 531 set at the corresponding position below the connecting plate 53, so that the top wall of its tail end abuts against the bottom wall of the groove in the second convex ring 531. At the same time, in this state, the connecting plate 53 slides down along the second sliding groove 76 opened on the corresponding walls on the left and right sides of the second seat 7, and is placed under the limit of the second sliding groove 76. Figure 1For example, the position is stable. Then, combined with the setting that the diameter of the through groove 512 and the groove body is slightly larger than the diameter of the pen refill, and the locking member 52 rotatably set in the threaded hole 511 opened on the side wall of the convex ring 51, the pen refill that abuts against the groove body of the second convex ring 531 in the through groove 512 is stably locked. Then, the connecting seat 5 is rotated so that it has a certain tilt angle on the fixed seat 4. The pen refill that is locked and fixed in the through groove 512 on the convex ring 51 by the locking member 52 then obtains a corresponding tilt angle simulating the human hand holding writing state. Then, after the rotation angle is adjusted, the two sets of second locking members 72 that are opened on both sides of the second seat body 7 and rotate in the second threaded hole 73 can be rotated to realize the connection seat 5. The locking and fixing process at the corresponding rotation angle, combined with the connecting rod 71 passing through the mounting hole 61 opened on the upper part of the second seat 7 at the corresponding position of the first seat 6, allows the first seat 6 and the second seat 7 to be adjusted in position by rotating synchronously. The first seat 6 can also slide up and down along the connecting rod 71 of the second seat 7 on the fixed seat 4 through the sliding grooves 62 opened on both sides. The connecting rod 71 is rotatably provided with multiple sets of third locking parts 75 through a threaded structure, and the compression spring 74 is sleeved on the connecting rod 71 between the third locking parts 75 and the first seat 6. In the static state, the compression spring 74 can make the first seat 6 fit against the second seat 7. At the same time, the rotation of multiple sets of third locking parts can also be achieved by adjusting the connecting rod 71. The component 75 can flexibly adjust the extension length and corresponding abutment force of the compression spring 74. Finally, it can control the third drive motor 13 in the three-axis slide module 1 so that the drive component 2 and its connecting component 3 can move along the Z-axis towards the base 100. This causes the tip of the pen refill, which is locked and stabilized by the locking component 52 in the through groove 512 on the convex ring 51, to contact and abut against the writing paper 110 such as cardboard placed on the base 100. Combined with the three-axis slide module 1 and its drive component 2 driving the connecting component 3 to move in different directions on the base 100, the process of drawing lines on the writing paper 110 such as cardboard placed on the base 100 by the operator is realized. The operator can judge the writing smoothness of the pen refill based on the changes in the depth of the drawn lines and whether there are any breaks in the lines. Compared with manual line drawing tests, this method can effectively reduce labor intensity while improving the stability of the test. In the process of ensuring that the Z-axis height of the connecting component 3 above the base 100 remains constant so that the pen refill can stably draw lines on the writing paper 110, the resistance of the pen refill against the writing paper 110 causes the first base 6, combined with the sliding grooves 62 on both sides, to have a tendency to move upward along the connecting rod 71 in the direction of pressing the spring 74. Under the resistance of the pen refill's tail end, the connecting plate 53 also has a tendency to slide upward synchronously with the second base 7 along the second sliding grooves 76 on both sides of the second base 7.In response to vibrations generated during the operation of the three-axis slide module 1 and uneven placement of the writing paper 110 leading to wrinkles and inconsistent heights between the paper 110 and the writing surface, the connecting component 3 with this structure can also provide a certain buffering effect for the pen refill held on the convex ring 51 during the writing smoothness detection process. Furthermore, the extension and retraction length of the compression spring 74 can be adjusted by rotating the multiple sets of third locking parts 75 on the connecting rod 71. Thus, under the pressure of the compression spring 74, the pen refill on the convex ring 51 of the first seat 6 can be placed on the cardboard or other writing paper on the base 100. Zhang 110 has different resisting forces, enabling the detection of writing smoothness of the pen refill under different writing pressures. This further improves the detection effect of the device on the writing smoothness of the pen refill, enhances the flexibility of use, and improves the accuracy of the detection results. In addition, during the initial detection phase, when a pen refill that meets the detection standard is locked in the through groove 512 of the convex ring 51 by the locking member 52 in the above-mentioned insertion method, the length of the connecting rod 71, the structural strength setting of the compression spring 74, and the structural characteristics of the writing paper 110 such as cardboard placed on the substrate are combined to ensure that the connecting rod 71 is in the mounting hole. When the maximum adjustment length of the multiple sets of third locking members 75 corresponding to the corresponding extension length above the first seat body 61 is such that the compression spring 74 sleeved around the connecting rod 71 is in the maximum compression state, and the pen refill that meets the testing requirements can draw lines and write normally, and the paper 110 used for writing by the pen refill will not be damaged under the corresponding writing force, the corresponding coordinates of the driving component 2 and the connecting assembly 3 at the lowest detection height along the Z-axis above the base 100 are marked, so that the third driving component in the three-axis slide module 1 can be used in subsequent testing. The height at which the motor 13 drives the drive component 2 and the connecting assembly 3 descends above the base 100 will not exceed the aforementioned calibrated coordinates. Combined with the pen refill insertion process where the connecting plate 53 is at the bottom of the second slide groove 76 and the second convex ring 531 abuts against the end of the pen refill, this ensures the uniformity and operational efficiency of pen refills of the same specification being locked to the corresponding length in the through groove 512 of the convex ring 51 by the locking member 52. This guarantees the effectiveness and stability of the connecting assembly 3, reducing unnecessary damage to the pen tip and the writing paper 110.

[0020] A pressure sensor 54 is also provided between the first seat 6 and the second seat 7. Multiple sets of pressure sensors 54 are provided and detachably mounted on the second seat 7. Figure 3As can be seen, the pressure sensor 54 can be inserted into the groove 77 provided above the second base 7. A wiring route is provided through the opening on one side of the groove 77. The corresponding wiring of the pressure sensor 54 can be connected to an external digital pressure switch or other terminal for displaying pressure values. In actual use, the first base 6, under the pressure of the spring 74, presses down on the pressure detection end of the pressure sensor 54 located in the groove 77 above the second base 7. Simultaneously, the pressure value can be displayed in real time using an external digital pressure switch or other terminal for displaying pressure values. When the operator rotates the multiple sets of third locking parts 75 on the connecting rod 71 to adjust the extension length of the spring 74, it is convenient to observe, judge, and record pressure value changes through an external digital pressure switch or other terminal for displaying pressure values, further improving the flexibility and stability of the connecting component 3. Furthermore, when the pressure sensor 54 is combined with the third drive motor 13 in the three-axis slide module 1 to drive the drive component 2 and the connecting component 3 to descend so that the pen tip initially contacts the writing paper 110 placed on the base 100, the pressure value displayed by the pressure sensor 54 and its external digital display pressure switch or other terminal for pressure value display changes. This allows for the calibration of the descent point of the third drive motor 13 in the Z-axis direction, ensuring that the pen tip has a certain contact force with the writing paper 110 and that the connecting component 3 plays its role in the writing smoothness detection process. The pressure value also allows for easy adjustment of the contact force between the pen tip and the writing paper 110, while also appropriately reducing unnecessary damage to the pen tip and the writing paper 110, thus improving the effectiveness and stability of this pen tip writing smoothness detection device.

[0021] The connecting seat 5 is detachably mounted on the fixed seat 4 via fourth locking members 30 provided on both sides. The fourth locking members 30 pass through the sliding groove 62 on the first seat body 6 and the fixed seat 4 respectively, and are rotatably mounted on the second seat body 7. Specifically, it can be combined with... Figure 3 As shown, the second seat 7 has a third threaded hole 78 adapted to the rotation of the fourth locking member 30, and the depth of the third threaded hole 78 does not exceed the corresponding wall thickness of the second seat 7. The fixed seat 4 has slots 40 on both sides for the fourth locking member 30 to pass through. During installation, the fourth locking member 30 can pass through the sliding groove 62 of the first seat 6 and the slot 40 of the fixed seat 4 respectively, and rotate in the third threaded hole 78 through the threaded structure. At the same time, combined with the length setting of the fourth locking member 30 and the depth setting of the third threaded hole 78, when the fourth locking member 30 is tightened in the third threaded hole 78, there is an appropriate gap between the wall surface corresponding to the head end of the fourth locking member 30 and the corresponding side wall of the first seat 6. This enables the connecting seat 5 to be detachably connected to the fixed seat 4 while ensuring the normal sliding process of the first seat 6 on the fixed seat 4 and the second seat 7, improving the structural detachability of the connecting component 3, and facilitating daily maintenance and later maintenance operations.

[0022] The aforementioned convex rings 51 and 531 are arranged in multiple sets along the first base 6 and the connecting plate 53 at intervals. A fifth locking member 65 for detachable connection of the convex rings 51 is also rotatably mounted on the first base 6. Figure 3 and Figure 4 As can be seen, the protruding ring 51 can be inserted into the matching ring groove 63 opened on the first base 6. Combined with the fourth threaded hole 64 opened on the first base 6 that communicates with the ring groove 63 and the fifth locking member 65 rotatably set on it, the protruding ring 51 in the ring groove 63 is locked and fixed, which further improves the structural detachability and disassembly flexibility of the connecting component 3. Moreover, the protruding ring 51 and the second protruding ring 531 can be set into multiple sets according to the usage requirements. Combined with the connecting plate 53 on both sides of the second base 7 at the lowest point of the second sliding groove 76, multiple sets of pen refills of the same specification can be installed. The tail end of the pen refill can be in the groove of multiple sets of second protruding rings 531 in a resisting state and locked by the locking member 52. The pen refills are locked and fixed in the through groove 512 of 51, which ensures the consistency of the locking length of multiple sets of pen refills on the first seat 6 below the connecting plate 53. Combined with the spaced arrangement of multiple sets of convex plates and second convex rings 531, in the subsequent writing smoothness detection process, the rotation of the connecting component 3 can be driven by the driving component 2. In conjunction with the first driving motor 11 and the second driving motor 12 in the three-axis slide module 1, the connecting component 3 is driven to move along the X-axis and Y-axis of the base 100, respectively. This facilitates the writing smoothness detection process under the premise of observing and judging the writing trajectory of the pen refills at the corresponding positions, thereby further improving the detection efficiency and applicability of this pen refill writing smoothness detection device.

[0023] The connecting plate 53 is provided with several sets of through holes 532 at the position corresponding to the second convex ring 531. Specifically, the diameter of the through holes 532 and the spacing between adjacent through holes 532 should be smaller than the outer diameter of the pen refill tail. The arrangement of several sets of through holes 532 is set so that when the pen refill tail is abutted in the groove of the second convex ring 531, it ensures that the tail will not get stuck in the through hole 532, while also allowing the second convex ring 531 to have a certain ventilation effect. This ensures that the ink inside the pen refill flows out normally during the writing smoothness test, and reduces the unnecessary impact on the uniformity of ink flow and the subsequent writing smoothness test results caused by the closure of the groove of the second convex ring 531.

[0024] An adjustment part 31 is also provided between the second seat 7 and the fixed seat 4. The adjustment part 31 includes multiple sets of spaced ball grooves 41 arranged circumferentially along the rotation direction of the second seat 7, and ball bearings 79 rotatably disposed on the left and right sides of the second seat 7 at corresponding positions to be adapted to and engaged with the ball grooves 41. Figure 3As can be seen, multiple sets of ball grooves 41 can be symmetrically arranged at corresponding intervals on both sides of the slot hole 40 on the fixed seat 4 according to actual testing requirements. When the connecting seat 5 is adjusted to rotate on the fixed seat 4, the balls 79 provided on the corresponding wall surfaces on both sides of the second seat 7 can be engaged in the ball grooves 41 at the corresponding positions. The addition of the structure of the adjustment part 31 can further improve the locking effect of the connecting seat 5 on the fixed seat 4 at the corresponding angle in combination with the locking process of the second locking member 72. At the same time, it can also further improve the operation speed of the connecting seat 5 on the fixed seat 4 at the corresponding angle adjustment process, and meet the testing requirements of the pen refill posture under different rotation angles.

[0025] The base 100 is also provided with multiple sets of fixing parts 8. Each fixing part 8 includes a support plate 81 and a support leg 82 slidably mounted on the support plate 81 via a support rod 83. A second compression spring 84 is sleeved on the support rod 83 located below the support plate 81, and multiple sets of sixth locking members 85 are rotatably mounted on the support rod 83 for detachable connection to the support leg 82. Specifically, from... Figure 1 As can be seen, the support plate 81 can be fixed at an appropriate height above the base 100 by being installed on the frame of the three-axis slide module 1 on both sides of the base 100 through bolted connections. Simultaneously, the support leg 82 can slide up and down through the connecting hole corresponding to the support plate 81 via the support rod 83. The second compression spring 84 sleeved on the support rod 83 then abuts against the support plate 81 below the connecting hole. A certain length of the support rod 83 extends above the connecting hole and, combined with the threaded structure at its end, is tightened by multiple sets of sixth locking components 85 to achieve the limiting and fixing of the support leg 82 on the support plate 81. Therefore, in actual use, it can be pulled... The movable support leg 82 slides and lifts up along the support plate 81, positioning the corresponding corners of the cardboard or other writing paper 110 placed on the base 100 below the support leg 82. Then, the support leg 82 is released, allowing it to slide downwards along the support plate 81 under the pressure of the compression spring 74, pressing down on the cardboard or other writing paper 110 until the corners of the entire cardboard or other writing paper 110 on the base 100 are pressed and fixed by multiple sets of fixing parts 8. The addition of multiple sets of fixing parts 8 can further improve the stability of the cardboard or other writing paper 110 placed on the base 100, reduce displacement that would affect the normal testing process, and improve testing stability.
