[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] See also Figures 1 to 3 The present invention provides a pen-shaped product detection device, comprising a base 1, a loading platform and a Z-axis module, wherein the loading platform and the Z-axis module are mounted on the base 1; the loading platform comprises a first loading surface 2, a second loading surface 3, a first floating moving module and a second floating moving module, the first loading surface 2 and the second loading surface 3 are parallel to each other, the first loading surface 2 and the second loading surface 3 are perpendicular to the center line of the Z-axis module, the first floating moving module is mounted on the first loading surface 2, and the second floating moving module is mounted on the second loading surface 3; a first auxiliary discharge element 21 is mounted on the first loading surface 2, a second auxiliary discharge element 31 is arranged on the second floating moving module, a first through hole is arranged on the board surface on which the first auxiliary discharge element 21 is mounted, the first auxiliary discharge element 21 and the second auxiliary discharge element 31 are connected, a pen-shaped product 7 extends out of the first through hole and is mounted in the first auxiliary discharge element 21 and the second auxiliary discharge element 31, and the second floating moving module moves and adjusts when the pen-shaped product 7 is not in a vertical state.

[0025] In an exemplary embodiment, the first floating moving module and the second floating moving module are frictionless slide rail mobile platforms. Since the mobile platform adopts a frictionless slide rail structure, the frictionless slide rail mobile platform can move accordingly under the action of a smaller force when the device is subjected to the force, thereby adaptively adjusting the position. The force exerted on the frictionless slide rail mobile platform is specifically the force applied when the product installed in the first auxiliary discharge element 21 and the second auxiliary discharge element 31 moves. Since the first auxiliary discharge element 21 is fixedly installed on the first loading surface 2, and the second auxiliary discharge element 31 is fixedly installed on the second floating moving module, but since the pen-shaped product 7 is not initially installed in a vertical state, the second auxiliary discharge element 31 will be offset by the force of the pen-shaped product 7, thereby driving the second floating moving module to move.

[0026] like Figure 2As shown, the loading platform is arranged in two layers, so that the first floating moving module and the second floating moving module are arranged relative to each other, and the first auxiliary material discharge component 21 and the second auxiliary material discharge component 31 are arranged relative to each other, and a through hole is arranged on the plate surface of the first auxiliary material discharge component 21 so that the first auxiliary material discharge component 21 and the second auxiliary material discharge component 31 can be connected, thereby increasing the installation space of the pen-shaped product 7 and reducing the installation tilt offset of the pen-shaped product 7. It should be noted that, as Figure 1 As shown, the base 1 is an operating table provided with a mounting frame, the loading table is installed on the table top of the operating table through a Y-axis movable slide rail 8, the Z-axis module is installed on the mounting frame, and the loading table can adjust the position in the Y-axis direction. Before the device starts working, it is necessary to move the loading table to directly below the Z-axis module so that the Z-axis module can be aligned with the first auxiliary discharge component 21, which is convenient for detecting the pen-shaped product 7, and aligning the center lines of the first auxiliary discharge component 21 and the Z-axis module can effectively improve the subsequent grasping accuracy of the insertion and extraction force detection of the pen-shaped product, and avoid measurement errors caused by inaccurate positioning of the pen-shaped product 7 on the machine. Before testing the insertion and extraction force of the pen cap part 72 of the pen-shaped product 77, the verticality of the pen-shaped product 7 is first calibrated. When the pen-shaped product 7 is in a straightened state, the pen cap part 72 is pulled out to test the insertion and extraction force of the part to be tested, thereby effectively reducing the influence of offset friction on the measurement of the insertion and extraction force, avoiding invalid measurement results caused by offset friction of the object to be tested, and improving the accuracy and precision of the insertion and extraction force measurement.

[0027] The second floating moving module includes a second straightening moving platform, and the second straightening moving platform includes a first sliding element and a second sliding element. The first sliding element is equipped with a first slide plate 32, the first slide plate 32 is equipped with a second sliding element, and the second slide plate 33 is equipped with the second sliding element. The center lines of the first sliding element and the second sliding element are perpendicular to each other, and the first sliding element and the second sliding element are both perpendicular to the center line of the Z-axis module.

[0028] In an exemplary embodiment, the first sliding element and the second sliding element are frictionless slide rails. The present application does not specifically limit the structures of the first sliding element and the second sliding element, that is, the first sliding element and the second sliding element can drive the first slide plate 32 and the second slide plate 33 to move. The first slide plate 32 is slidably mounted on the first sliding element, and the first sliding element provides the first slide plate 32 with a movable range of motion in the X direction. The second slide plate 33 is slidably mounted on the second sliding element, and the second sliding element provides the second slide plate 33 with a movable range of motion in the Y-axis direction. It should be noted that the first slide plate 32 and the second slide plate 33 are both planar plate structures. The present application does not specifically limit the shapes of the first slide plate 32 and the second slide plate 33, and the first slide plate 32 and the second slide plate 33 can be perpendicular to the center line of the Z-axis module. The present application does not specifically limit the setting direction of the first sliding element and the second sliding element, and an angle can be present between the center lines of the first sliding element and the second sliding element. In this exemplary embodiment, the second floating movable module is provided with slide rails in the X and Y directions so that the slide plate installed on the corresponding slide rail can slide along the corresponding direction, and further can realize the position adjustment of the second auxiliary discharge element 31 within any range, thereby improving the flexibility and accuracy of equipment correction.

[0029] The second floating moving module further includes a first adjusting element 34 , which is mounted on both sides of the first slide plate 32 and the second slide plate 33 , and is used to adjust the range of movement of the first slide plate 32 and the second slide plate 33 .

[0030] In an exemplary embodiment, first adjustment elements 34 are further provided on both sides of the board surface of the first slide plate 32 and the second slide plate 33. In this exemplary embodiment, the first adjustment element 34 is a fine-tuning knob, and the present application does not specifically limit the structure of the first adjustment element 34. The first adjustment element 34 can limit the range of motion of the first slide plate 32 and the second slide plate 33. Specifically, the adjustment element of the first slide plate 32 is installed on the side of the board surface perpendicular to the moving direction of the first slide plate 32, and the adjustment element of the second slide plate 33 is installed on the side of the board surface perpendicular to the moving direction of the second slide plate 33. The sides of the board surfaces of the first slide plate 32 and the second slide plate 33 where the adjustment elements are installed are both provided with internal threaded blind holes, and the first adjustment element 34 is a screw adapted to the internal threaded blind holes. It should be noted that the first adjusting element 34 is used to adjust the movable range of the first slide 32 and the second slide 33. That is, before the equipment is straightened, the present application can preliminarily limit the movable range of the first slide 32 and the second slide 33 by setting the first adjusting element 34, i.e., the fine-tuning knob. First, adjust the first adjusting element 34 on both sides of each board surface to limit the movable range of the first slide 32 and the second slide 33, thereby reducing the distance required for adjustment of the subsequent straightening displacement, reducing the difficulty of straightening the pen-shaped product 7, and improving the measurement accuracy.

[0031] The first floating moving module includes a first straightening moving platform, and the center line of the first auxiliary discharge element 21 is located on the same straight line as the center line of the first straightening moving platform; the first straightening moving platform includes a third sliding element and a fourth sliding element, a third slide plate 22 is installed on the third sliding element, a fourth sliding element is installed on the third slide plate 22, and a fourth slide plate 23 is installed on the fourth sliding element; the center lines of the third sliding element and the fourth sliding element are perpendicular to each other, and the third sliding element and the fourth sliding element are both perpendicular to the center line of the Z-axis module.

[0032] The third sliding element and the fourth sliding element are frictionless slide rails. The present application does not specifically limit the structure of the third sliding element and the fourth sliding element. That is, the third sliding element and the fourth sliding element can drive the third slide plate 22 and the fourth slide plate 23 to move. The third slide plate 22 is slidably mounted on the third sliding element, and the third sliding element provides the third slide plate 22 with a movable range of motion in the X direction. The fourth slide plate 23 is slidably mounted on the fourth sliding element, and the fourth sliding element provides the fourth slide plate 23 with a movable range of motion in the Y-axis direction. It should be noted that the third slide plate 22 and the fourth slide plate 23 are both planar plate structures. The present application does not specifically limit the shapes of the third slide plate 22 and the fourth slide plate 23. The plate surfaces of the third slide plate 22 and the fourth slide plate 23 can be perpendicular to the center line of the Z-axis module. The present application does not specifically limit the setting direction of the third sliding element and the fourth sliding element. It is sufficient that there is an angle between the center lines of the third sliding element and the fourth sliding element. In this exemplary embodiment, the first floating movable module is provided with slide rails in the X and Y directions so that the slide plate installed on the corresponding slide rails can slide along the corresponding directions, and further, the position of the first clamping claw module installed on the first floating movable module can be adjusted within any range, thereby improving the flexibility and clamping accuracy of the clamping claw in correcting the pen-shaped product 7.

[0033] The first floating moving module further includes a second adjusting element 24 , which is mounted on both sides of the third slide plate 22 and the fourth slide plate 23 , and is used to adjust the range of movement of the third slide plate 22 and the fourth slide plate 23 .

[0034] In the exemplary embodiment, second adjustment elements 24 are further provided on both sides of the board surface of the third slide plate 22 and the fourth slide plate 23. In the exemplary embodiment, the second adjustment element 24 is a fine-tuning knob, and the present application does not specifically limit the structure of the second adjustment element 24. The second adjustment element 24 can limit the range of motion of the third slide plate 22 and the fourth slide plate 23. Specifically, the adjustment element of the third slide plate 22 is installed on the side of the board surface perpendicular to the moving direction of the third slide plate 22, and the adjustment element of the fourth slide plate 23 is installed on the side of the board surface perpendicular to the moving direction of the fourth slide plate 23. The sides of the board surfaces of the third slide plate 22 and the fourth slide plate 23 on which the second adjustment element 24 is installed are both provided with internal threaded blind holes, and the second adjustment element 24 is a screw adapted to the internal threaded blind holes. It should be noted that the second adjusting element 24 is used to adjust the movable range of the third slide 22 and the fourth slide 23. That is, before the equipment performs straightening work, the present application can preliminarily limit the movable range of the third slide 22 and the fourth slide 23 by setting the second adjusting element 24, that is, the fine-tuning knob. First, adjust the second adjusting element 24 on both sides of each board surface to limit the movable range of the third slide 22 and the fourth slide 23, reduce the distance that the first clamp module needs to adjust for displacement when calibrating the pen-shaped product 7, reduce the difficulty of straightening the pen-shaped product 7, and improve processing efficiency and measurement accuracy.

[0035] The first floating moving module also includes a first clamping module, which includes a first clamping drive device 25 and a first clamping jaw 26. The first clamping jaw drive device 25 drives the first clamping jaw 26 to clamp toward the center of the clamping jaw. The end of the first clamping jaw 26 that clamps the pen-shaped product 7 is provided with a first claw tooth, and the arc radius of the first claw tooth is equal to the radius of the pen-shaped product 7.

[0036] In an exemplary embodiment, the first clamp module is mounted on the second slide plate 33, and the center of the claws of the first clamp 26 is located on the same straight line as the center of the first auxiliary discharge element 21, that is, the first clamp 26 only needs to clamp the pen-shaped product 7, and no alignment is required. In this exemplary embodiment, the diameter of the claws of the first clamp 26 is 8.9 mm, and the diameter of the pen-shaped product 7 is 8.9 mm, that is, the diameter of the claws of the first clamp 26 is matched with the diameter of the pen-shaped product 7, and the tolerance range is 0.03 mm-0.05 mm. It should be noted that the present application clamps the pen-shaped product 7 installed in the first auxiliary discharge element 21 and the second auxiliary discharge element 31 by clamping with the first clamp 26. Since the first clamping jaw 26 is provided with claw teeth, and the diameter of the claw teeth is adapted to the diameter of the pen-shaped product 7, the above-mentioned first clamping jaw 26 can also correct the product when clamping the product, thereby ensuring the straightness of the pen-shaped product 7, facilitating the later detection of the insertion and extraction force of the pen cap part 72 of the pen-shaped product 7, reducing the offset friction caused by the tilt of the product, and improving the precision and accuracy of the measurement.

[0037] The inner diameter of the first auxiliary discharge element 21 and the second auxiliary discharge element 31 is larger than the diameter of the pen-shaped product 7. In the exemplary embodiment, the first auxiliary discharge element 21 and the second auxiliary discharge element 31 are both cylindrical structures. The present application does not specifically limit the shapes of the first auxiliary discharge element 21 and the second auxiliary discharge element 31. The first auxiliary discharge element 21 and the second auxiliary discharge element 31 can preliminarily position the pen-shaped product 7 and facilitate product installation. The diameter of the first auxiliary discharge element 21 and the second auxiliary discharge element 31 is 10 mm. The diameter of the first auxiliary discharge element 21 and the second auxiliary discharge element 31 is larger than the diameter of the pen-shaped product 7, which is more conducive to discharge, ensuring that the product is more conveniently placed in the installation position, and the discharge process is convenient and labor-saving.

[0038] The Z-axis module includes an up-and-down moving driving device and an insertion and extraction force detection module, and the insertion and extraction force detection module is slidably mounted on the up-and-down moving driving device through the first mounting frame 5. In an exemplary embodiment, the insertion and extraction force detection module is used to detect the pulling force of the pen cap portion 72 of the pen-shaped product 7 being pulled out from the pen shaft portion 71, and the up-and-down moving driving device is used to adjust the position of the insertion and extraction force detection module according to the product height, and move the insertion and extraction force detection module up and down. It should be noted that, if Figure 4 As shown, the center line of the insertion and extraction force detection module is located on the same straight line as the center line of the first auxiliary discharge element 21, which is convenient for clamping and grasping the pen-shaped product 7, further reducing the offset friction when the pen cap part 72 of the pen-shaped product 7 is extracted, and improving the measurement precision and accuracy.

[0039] The plug-in and extraction force detection module includes a second clamping jaw module and a tension sensing element 62, and the tension sensing element 62 is installed between the first mounting frame 5 and the second clamping jaw module. In an exemplary embodiment, the tension sensing element 62 is a pressure sensor, and the pressure sensor is arranged between the first mounting frame 5 and the second clamping jaw module, and the pressure sensor is used to detect the tension of pulling the cap part 72 of the pen-shaped product 7 out of the pen shaft part 71. It should be noted that the present application does not make specific limitations on the structure of the pressure sensor, and the tension sensing element 62 can measure the tension of pulling the cap part 72 of the pen-shaped product 7 out of the pen shaft part 71. The plug-in and extraction force detection device of the present application has a simple structure, which is convenient for adjusting and repairing the installation position of each structure.

[0040] The second clamping jaw module includes a second clamping jaw driving device 6 and a second clamping jaw 61. The second clamping jaw driving device 6 drives the second clamping jaw 61 to clamp toward the center of the clamping jaw. Each second clamping jaw 61 is provided with a second claw at the end of the pen-shaped product 7. In the exemplary embodiment, the diameter of the second claw is 8.9 mm, and the diameter of the second claw is adapted to the diameter of the pen-shaped product 7. The present application does not specifically limit the number of the second claws. The second clamping jaw 61 can clamp the cap portion 72 of the pen-shaped product 7. It should be noted that the first clamping jaw 26 clamps the pen shaft portion 71 of the pen-shaped product 7, and the second clamping jaw 61 clamps the pen cap portion 72 of the pen-shaped product 7. The first clamping jaw 26 and the second clamping jaw 61 cooperate to realize the action of pulling the pen cap portion 72 from the pen shaft portion 71, so as to achieve the purpose of measuring the pulling force of pulling the pen cap portion 72 from the pen shaft portion 71. The device has a simple structure, and the pen-shaped product 7 is straightened before measuring the pulling force value, thereby improving the measurement accuracy of the pulling force value.

[0041] The pen-shaped product 7 includes a nib, a barrel 71 and a cap 72, the nib is installed in the second auxiliary discharge element 31, and the tension sensing element 62 is used to measure the tension value of the second clamp 61 pulling the cap 72 out of the barrel 71. In an exemplary embodiment, the end of the pen-shaped product 7 is provided with a nib, and the nib is installed in the second auxiliary discharge element 31. It should be noted that two upper and lower auxiliary discharge elements are provided to install the product, and the diameters of the first auxiliary discharge element 21 and the second auxiliary discharge element 31 are set accordingly according to the diameter of the pen-shaped product 7, and the straightness of the product is initially limited, so that no matter how the pen-shaped product 7 is tilted, it is within the grasping range of the first clamp 26 and the second clamp 61, ensuring that the tension value measurement process of the product can be carried out normally, reducing the working errors of the equipment, and improving the measurement efficiency of the tension value of the pen-shaped product 7.

[0042] Working principle: First, the pen-shaped product 7 is installed in the first auxiliary feeding element 21 and the second auxiliary feeding element 31. Since the diameters of the two auxiliary feeding elements for installing the pen-shaped product 7 are slightly larger than the diameter of the pen-shaped product 7, the pen-shaped product 7 is not completely vertical after installation. The pen tip will give a tilting force to the second auxiliary feeding element 31 due to the tilt, that is, the second auxiliary feeding element 31 tilts in the force direction to drive the second slide 33 to move. After the pen-shaped product 7 is installed in place, the first clamping jaw 26 receives the start signal and starts to retract the clamping jaw to clamp the pen shaft 71 of the pen-shaped product 7, thereby initially positioning the pen-shaped product 7. Specifically, since the first auxiliary feeding element 21 is fixedly arranged on the first floating moving module, after the first clamping jaw 26 clamps the pen-shaped product 7, the pen tip installed in the second auxiliary feeding element 31 gives the second auxiliary feeding element 31 a tilting force again, so that the second auxiliary feeding element 31 moves again. When the pen-shaped product 7 itself is bent, the first clamp 26 clamps the pen shaft 71 near the pen cap 72. After the first clamp 26 clamps the pen-shaped product 7, the second floating movable module moves and adjusts accordingly due to the traction force of the pen-shaped product 7. Usually, the bending degree of the pen-shaped product 7 is small and is within the grasping range of the first clamp 26. The straightening of the pen-shaped product 7 is achieved through the cooperation of the first floating movable module and the second floating movable module.

[0043] After the straightening work of the pen-shaped product 7 is completed, the Z-axis module receives the start signal, and the up-down moving drive device drives the plugging and pulling force detection module to move down to the horizontal height of the pen cap part 72, and then the second clamp 61 tightens and clamps the pen cap part 72. Then the up-down moving drive device is started again, and the first clamp 26 clamps the pen shaft part 71 and the second clamp 61 cooperates to pull out the pen cap part 72 to achieve the separation of the pen cap part 72 and the pen shaft part 71. At this time, the pressure sensor installed between the first mounting frame 5 and the second clamp 61 senses the tension value and determines whether the tension value is within a preset range. Furthermore, the pressure sensor is connected to an alarm device in communication. When the measured tension value does not meet the preset value, the alarm device is activated and the product is judged to be defective. When the tension value is within the preset range, the product is judged to be qualified, the process is terminated, and the operation is repeated. The present application corrects the verticality of the pen-shaped product 7 by setting a floating movable module, thereby effectively reducing the influence of offset friction on the measurement of the insertion and extraction force, avoiding the offset friction of the object to be measured and causing the measurement result to be invalid, and improving the measurement precision and accuracy of the insertion and extraction force of the pen cap part 72 of the pen-shaped product 7.
