Description

Technical Field

[0001] The utility model generally relates to the technical field of writing pen production and manufacturing, and in particular to a detection device and writing pen assembly equipment. Background Art

[0002] The double-ball pen tip is a pen tip used in straight liquid writing pens, which has the advantages of smooth writing and uniform ink output. Among them, there is a ball in the inner hole of the pen tip, and the shape of the ball is only about 0.6 mm. Before the pen tip is fully assembled, due to the difference in material, volume and weight between the ball itself and the pen tip, it will be affected by factors such as temperature, humidity, static electricity and magnetism in the assembly environment, and the position height of the ball in the inner hole of the pen tip will vary. At the same time, the smallest point of the inner hole of the pen tip is only 1.15 mm, but the depth reaches 11 mm. The detection probe needs to be thin and long, and the detection probe needs to be built into the inner hole of the pen tip for detection. It is difficult to ensure the accuracy of the detection, resulting in the phenomenon of missing and over-installing of balls, and it is impossible to completely realize the defective selection through effective detection methods in subsequent processes. Only through long-term timeliness verification can it be verified whether the ball is missing, and it is difficult to ensure the consistency of cost and quality. Utility Model Content

Since the detection piece and the detection movable component are placed outside the workpiece to be detected, the detection process is independent of the internal size of the workpiece to be detected, which reduces the difficulty of detection and improves the detection production efficiency.

[0047] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0048] This embodiment provides a detection device. During the detection and assembly of a writing pen, the detection device is used to detect detection elements such as internal parts of the writing pen. For example, the detection element can be a ball of the writing pen, and the ball includes but is not limited to a writing bead, a valve bead, etc. Among them, the workpiece to be detected can specifically refer to the nib of the writing pen. The nib is provided with an open end, and an inner hole is provided in the nib. The inner hole and the open end are connected. The inner hole accommodates a writing bead, a valve bead, and a spring, etc. One side of the valve bead abuts the spring, and the other side abuts the writing bead. The writing bead is at least partially exposed at the open end, which is convenient for users to write, and can maintain zero-gap airtightness at any time. No auxiliary structure is required to protect the airtightness of the nib, and it can also ensure that the nib does not leak ink, does not dry ink, and other problems, thereby maintaining a good writing state. Since the nib of the writing pen has both a writing bead and a valve bead, the writing pen is specifically a double-ball nib.

[0049] The minimum value of the inner hole of the existing pen tip is about 1.15mm, and the depth of the inner hole is about 11mm. Due to the small radial dimension of the inner hole and the relatively deep depth, it is difficult to accurately detect the presence and position height of each ball in the inner hole, which makes it easy for the balls to be missed or over-installed, affecting the quality of the finished writing pen.

[0050] To solve this problem, Figure 1-Figure 2 As shown, this embodiment provides a detection device for detecting the ball of a writing pen. The detection device comprises a bearing mechanism 1, and the bearing mechanism 1 is used to carry a workpiece to be detected.

[0051] The bearing mechanism 1 includes a bearing base 11 and a fixture 12. The fixture 12 is arranged on the bearing base 11, and is used to clamp and fix the workpiece to be detected, realize the installation and fixation of the workpiece to be detected, and provide a certain support force for the workpiece to be detected. The bearing base 11 can be a rectangular structure, a disc structure or other regular or irregular structures. The bearing base 11 can also be a fixed structure or a movable structure. For example, the bearing base 11 is a disc structure, and a plurality of fixtures 12 are arranged on the bearing base 11 along the circumference of the bearing base 11. The output end of the rotary drive source (not shown in the figure) is connected to the bearing base 11. The rotary drive source drives the bearing base 11 to rotate, so that the detection device can continuously detect the workpiece to be detected, and the production efficiency is relatively high.

[0052] like Figure 1-Figure 2 As shown, the detection device further includes a detection mechanism 2, which includes a mounting base 21, a detection movable component 22 and a detection member 23. The mounting base 21 can be a rectangular structure, an L-shaped structure or other regular or irregular structures.

[0053] The mounting base 21 provides a mounting position for the detection movable assembly 22 and provides a certain support force for the detection movable assembly 22. The detection movable assembly 22 is movably arranged on the mounting base 21, and the detection movable assembly 22 can move relative to the mounting base 21. The detection member 23 can be an infrared sensor, a photoelectric sensor, etc. The detection member 23 is used to detect the position of the detection movable assembly 22. The mounting position of the detection member 23 is not limited. The detection member 23 can be arranged on the mounting base 21 or at other positions of the detection device.

[0054] The detection device also includes a driving mechanism 3, which is connected to the mounting base 21. The driving mechanism 3 drives the detection movable component 22 to move toward the direction close to the supporting mechanism 1 through the mounting base 21, so that the detection movable component 22 can move relative to the mounting base 21 after abutting against the workpiece to be detected. The detection member 23 is used to detect the position of the detection movable component 22.

[0055] The driving mechanism 3 can provide the detection mechanism 2 with a driving force to generate relative movement with the supporting mechanism 1. For example, the driving mechanism 3 can provide a lifting driving force for the detection mechanism 2. Under the driving action of the driving mechanism 3, after the detection movable component 22 contacts and presses against the detection element of the workpiece to be detected, the detection element provides a reaction force for the detection movable component 22, and the detection movable component 22 moves relative to the mounting base 21 in a direction away from the detection element. The detection member 23 can detect the position of the detection movable component 22, and judge whether the detection element of the workpiece to be detected is missing or over-installed according to the position change of the detection movable component 22.

[0056] In the detection device provided in this embodiment, the detection member 23 does not directly extend into the workpiece to be detected and detect the detection element of the workpiece to be detected, but after the detection movable component 22 contacts the workpiece to be detected, the detection member 23 indirectly determines the presence or amount of the detection element in the workpiece to be detected by detecting the position of the detection movable component 22. Since the detection member 23 and the detection movable component 22 are placed outside the workpiece to be detected, the detection process is independent of the internal size of the workpiece to be detected, which reduces the detection difficulty and improves the detection production efficiency.

[0057] In one embodiment, Figure 1-Figure 2 As shown, the driving mechanism 3 includes at least one of a lifting driving source 31 and a cam structure (not shown in the figure).

[0058] Exemplarily, the driving mechanism 3 includes a lifting driving source 31, the lifting driving source 31 can be specifically selected from a lifting cylinder, the lifting cylinder can be specifically selected from a precision slide cylinder, the lifting driving source 31 can also be selected from a linear motor, the output end of the lifting driving source 31 is connected to the mounting base 21, and the lifting driving source 31 drives the mounting base 21 to perform lifting motion; the driving mechanism 3 can also include a cam structure, the cam structure specifically includes a rotating motor and a cam, the output end of the rotating motor is connected to the cam, the rotating motor drives the cam to rotate, and the mounting base 21 and the surface of the cam are directly abutted or indirectly abutted through a pressure block, etc. Abutment, with the rotation of the cam, the mounting base 21 can move up and down; the driving mechanism 3 can also have a lifting drive source 31 and a cam structure at the same time, for example, the surface of the cam directly abuts or indirectly abuts the lifting shaft 32 through a pressure block, etc., with the rotation of the cam, the lifting shaft 32 can move up and down to achieve a first-level lifting movement, the lifting shaft 32 is directly or indirectly connected to the lifting drive source 31 through a connecting seat and other structures, the output end of the lifting drive source 31 is connected to the mounting base 21, and the lifting drive source 31 drives the mounting base 21 to perform lifting and lowering movements to achieve a second-level lifting and lowering movement. In this way, the first-level lifting can achieve preliminary rough lifting in the lifting movement, and the second-level lifting can achieve fine lifting in the lifting movement. Of course, the first-level lifting can be used to detect other parameters, such as pen tips.

[0059] In one embodiment, Figure 3-Figure 4 As shown, the mounting base 21 includes a vertical portion and a horizontal portion, and the horizontal portion and the vertical portion are perpendicular to each other to form an L-shaped structure. The lifting drive source 31 of the driving mechanism 3 is connected to the vertical portion, the horizontal portion is arranged in parallel with the bearing base 11 of the bearing mechanism 1, and the detection mechanism 2 is arranged on the horizontal portion, and the horizontal portion is used to carry the detection mechanism 2. In this way, the lifting and carrying of the mounting base 21 do not interfere with each other, and the reliability is good.

[0060] In one embodiment, the detection movable component 22 includes a detection needle 221, which is inserted into the mounting base 21 and slidably cooperates with the mounting base 21. The detection needle 221 can be inserted into the inner hole of the workpiece to be detected and can abut against the detection element.

[0061] The detection needle 221 can also be called a detection shaft. The driving mechanism 3 drives the detection needle 221 to move downward and gradually approach the workpiece to be detected through the mounting base 21, so that the detection needle 221 is inserted into the inner hole of the workpiece to be detected. As the detection needle 221 is pressed down, the detection needle 221 contacts and abuts against the detection element, and the detection element pushes the detection needle 221 to move away from the detection element relative to the mounting base 21. The position change of the detection needle 221 is used to determine the presence or absence, quantity or height position of the detection element. It can be understood that the detection member 23 can directly detect the position change of the detection needle 221, and can also detect other parts in the detection movable component 22 that move with the movement of the detection needle 221.

[0062] The radial clearance between the detection needle 221 and the inner hole is 0.1 mm to 0.3 mm.

[0063] If the radial clearance between the detection needle 221 and the inner hole is less than 0.1mm, the radial clearance is relatively small. Since the diameter of the valve ball represented by the detection element is only 0.6mm, the weight is light, and the inner diameter of the inner hole is relatively small and the depth is relatively deep, the matching clearance between the detection needle 221 and the inner hole needs to be controlled very accurately. If the matching clearance is too small, friction or collision will occur, causing the detection needle 221 to deform or generate static electricity; if the matching clearance between the detection needle 221 and the inner hole of the pen tip is too large, since the outer diameter of the detection needle 221 is too small and the length is too long, it cannot withstand the load generated by the detection action, so that the accuracy cannot be guaranteed and deformation and fracture occur. For this reason, by setting the radial clearance between the detection needle 221 and the inner hole to 0.1mm~0.3mm, the radial clearance is within a reasonable range, which can reduce the collision caused by friction, and the inner hole can guide the detection needle 221 to avoid deformation and easy fracture of the detection needle 221, thereby improving the stability of the detection mechanism 2 and reducing the risk of false detection.

[0064] In addition, the material of the detection needle 221 is made of non-magnetic materials, such as metal, plastic, etc., to avoid the detection needle 221 having adsorption during the detection action, which will lift the detection element, causing the detection element to fall after being detected but adsorbed, thereby reducing the phenomenon of missing detection elements. Therefore, in the production and manufacturing process of the detection needle 221, it is necessary to comprehensively consider the rationality of design, material matching, heat treatment process, machining process and precision requirements.

[0065] In one embodiment, the detection movable component 22 also includes a detection amplifier 222, which is arranged on the mounting base 21. The end of the detection needle 221 away from the supporting mechanism 1 can push one end of the detection amplifier 222 to make the detection amplifier 222 rotate relative to the mounting base 21. The detection component 23 is used to detect the position of the other end of the detection amplifier 222.

[0066] Specifically, the detection amplifier 222 includes a contact portion 2222 , a rotating portion 2223 and a detection portion 2224 , and two ends of the rotating portion 2223 are connected to the contact portion 2222 and the detection portion 2224 , respectively. A rotating seat is provided on the mounting base 21, and the rotating portion 2223 of the detection amplifier 222 is rotatably connected to the rotating seat through a rotating shaft. The rotating portion 2223 can be a cylindrical structure, and the detection amplifier 222 can rotate relative to the rotating seat through the rotating shaft. The end of the detection amplifier 222 close to the detection needle 221 is the contact portion 2222, and the contact portion 2222 can be a rectangular structure. The top of the detection needle 221 can push the contact portion 2222 of the detection amplifier 222, and the end of the detection amplifier 222 away from the detection needle 221 is the detection portion 2224, and the detection portion 2224 can be a fan-shaped structure. The detection amplifier 222 is essentially a lever structure. After the upper end of the detection needle 221 lifts or lowers the contact portion 2222 of the detection amplifier 222, the detection amplifier 222 rotates relative to the rotating seat, so that the detection portion 2224 of the detection amplifier 222 changes its position, which is convenient for the detection member 23 to detect the detection portion 2224.

[0067] In this way, the detection amplifier 222 moves with the movement of the detection needle 221, and the detection member 23 directly detects the detection amplifier 222, which is used to characterize the movement of the detection needle 221, so as to achieve the purpose of indirectly detecting the detection element. By utilizing the rotational movement of the detection amplifier 222, the movement direction is changed, which facilitates the spatial arrangement between the detection member 23 and the detection amplifier 222, facilitates detection, and improves detection accuracy.

[0068] Since the size of the detection element is relatively small, even if the detection element is over-installed or missing, the size change difference is relatively small when the detection element 23 directly detects the detection element, which is inconvenient to detect. Therefore, the distance between the force application position of the detection needle 221 on one end of the detection amplifier 222 and the rotation center of the detection amplifier 222 is L1, and the distance between the detection position of the detection element 23 on the other end of the detection amplifier 222 and the rotation center of the detection amplifier 222 is L2; ​​wherein L1<L2.

[0069] According to the lever principle, the rotation angles of one end and the other end of the detection amplifier 222 are the same, so the lifting height of the detection needle 221 on one end of the detection amplifier 222 is smaller than the lowering height of the other end of the detection amplifier 222, so as to amplify the movement stroke of the detection needle 221 and facilitate detection by the detection part 23.

[0070] In one embodiment, a plurality of detection slots 2221 are disposed at the other end of the detection amplifier 222 , and the detection element 23 is used to detect one of the plurality of detection slots 2221 .

[0071] A plurality of detection slots 2221 can be evenly arranged along the circumference of the detection portion 2224 of the detection amplifier 222. When the detection portion 2224 rotates with the rotating portion 2223, the detection member 23 can detect the positions of different detection slots 2221 to indicate different positions of the detection needle 221, so as to achieve the purpose of detecting the detection element. The detection member 23 is arranged toward the detection slot 2221, that is, the detection slot 2221 is detected by a cross-beam method.

[0072] There are five detection slots 2221, which are evenly arranged circumferentially along the detection portion 2224 of the detection amplifier 222. The five detection slots 2221 can be the first detection slot, the second detection slot, the third detection slot, the fourth detection slot and the fifth detection slot from top to bottom. Of course, the number of the detection slots 2221 can also be one or other numbers.

[0073] For example, in the initial state, the detection amplifier 222 is in a horizontal state, and the detection member 23 can detect the detection slot 2221 located in the middle, that is, the third detection slot. The driving mechanism 3 drives the detection needle 221 to descend to a preset height, which is slightly greater than the distance between the detection element and the opening end of the pen tip. After the driving mechanism 3 drives the detection needle 221 to descend and contact the detection element, the detection element can lift the detection needle 221, and then the detection needle 221 lifts the contact portion 2222 of the detection amplifier 222, and the detection portion 2224 of the detection amplifier 222 descends. The detection member 23 detects the second detection slot, which means that there is a detection element in the workpiece to be detected and the number of detection elements is exactly one; if the detection member 23 detects the first detection slot, it means that there is a detection element in the workpiece to be detected and the number of detection elements is two, and there is a situation of multiple installation. If the driving mechanism 3 drives the detection needle 221 to descend, after the detection needle 221 contacts the workpiece to be detected, the detection needle 221 presses down the contact part 2222 of the detection amplifier 222, and lifts up the detection part 2224 of the detection amplifier 222, and the detection part 23 detects the fourth detection slot or the fifth detection slot, which means that there is no detection element in the workpiece to be detected, there is a missing installation, or the height position of the detection element is too low, and further detection is required.

[0074] In one embodiment, Figure 2-Figure 4 As shown, the detection movable component 22 also includes an adapter 223 , which can also be called a connecting joint. The adapter 223 is connected to at least one of the detection needle 221 and the detection amplifier 222 .

[0075] Exemplarily, the adapter 223 can be set at the top of the detection needle 221. As the detection needle 221 descends and rises, the adapter 223 contacts the contact portion 2222 of the detection amplifier 222. The adapter 223 is used to increase the contact area between the detection needle 221 and the detection amplifier 222, thereby improving the accuracy and reliability of the detection.

[0076] Exemplarily, the adapter 223 can be connected to the side of the contact portion 2222 away from the rotating portion 2223, the detection needle 221 contacts the adapter 223, and drives the detection amplifier 222 to rotate through the adapter 223, and the adapter 223 is used to increase the contact area between the detection needle 221 and the detection amplifier 222, thereby improving the accuracy and reliability of detection.

[0077] Of course, the adapter 223 can also be connected to the detection needle 221 and the detection amplifier 222 at the same time. The adapter 223 serves as an intermediate connection between the detection needle 221 and the detection amplifier 222, and increases the contact area between the detection needle 221 and the detection amplifier 222.

[0078] Specifically, the adapter 223 includes a guide portion 2231, which is disposed on the mounting base 21. The guide portion 2231 is provided with a guide hole 2230, and the detection needle 221 is passed through the guide hole 2230. The guide hole 2230 guides the detection needle 221 to ensure the smoothness of the movement of the detection needle 221 and reduce the deformation and bending of the detection needle 221.

[0079] The adapter 223 further includes a connecting portion 2232 , which is disposed on a side of the guide portion 2231 away from the detection needle 221 . One end of the connecting portion 2232 can abut against the detection needle 221 , and the other end is connected to the detection amplifier 222 .

[0080] Specifically, the connecting portion 2232 and the detecting needle 221 are arranged correspondingly, that is, the orthographic projection of the connecting portion 2232 relative to the horizontal portion of the mounting base 21 and the orthographic projection of the detecting needle 221 relative to the horizontal portion at least partially overlap. When the detecting needle 221 is lifted up, the upper end of the detecting needle 221 contacts the connecting portion 2232, and the contact portion 2222 of the detecting amplifier 222 is pushed to move through the connecting portion 2232.

[0081] The adapter 223 provided in the present disclosure has a guiding portion 2231 and a connecting portion 2232. While increasing the contact area between the detection needle 221 and the detection amplifier 222, it can also guide and limit the detection needle 221, thereby improving the verticality of the detection needle 221 during the lifting process, thereby ensuring the accuracy and consistency of the detection.

[0082] It should be particularly noted that the guide portion 2231 and the mounting base 21 are not connected by bolts, welding or the like, otherwise the detection needle 221 cannot drive the detection amplifier 222 to move through the adapter 223 .

[0083] In one embodiment, the position between the connecting portion 2232 and the detection amplifier 222 is adjustable. In this way, the position of the adapter 223 is not fixed, but movable. By adjusting the position of the connecting portion 2232, the position of the detection needle 221 relative to the workpiece to be detected is adjusted to ensure that the detection needle 221 and the inner hole of the workpiece to be detected can be accurately aligned. At the same time, by adjusting the position of the connecting portion 2232 relative to the detection amplifier 222, the amplification ratio of the action stroke can be adjusted.

[0084] Specifically, one of the detection amplifier 222 and the connecting portion 2232 is provided with a strip groove, and the other is provided with an adjustment shaft, which can slide along the extension direction of the strip groove and engage with it, so as to achieve the purpose of active adjustment between the detection amplifier 222 and the contact portion 2222 and the connecting portion 2232 of the adapter 223. Of course, the active position adjustment between the adapter 223 and the detection amplifier 222 can also be other ways, which are not limited in this embodiment.

[0085] In one embodiment, Figure 2-Figure 4 As shown, the detection device further includes an alignment mechanism 4, which includes a positioning member 41 and an alignment measuring member 42. The positioning member 41 may be a positioning pin shaft, and the positioning member 41 is arranged on the mounting base 21 and corresponds to the detection movable assembly 22. The alignment measuring member 42 may be a differential head, and the alignment measuring member 42 is arranged on the positioning member 41 to detect the position of the detection member 23 relative to the detection movable assembly 22. The alignment measuring member 42 is used to monitor the position of the detection member 23 to avoid the situation where the detection member 23 does not detect the detection slot 2221 accurately.

[0086] The present embodiment also provides a writing pen assembly device, including the above-mentioned detection device. The driving mechanism 3 can provide a driving force for the detection mechanism 2 to generate relative movement with the supporting mechanism 1. For example, the driving mechanism 3 can provide a lifting driving force for the detection mechanism 2. Under the driving action of the driving mechanism 3, after the detection movable component 22 contacts and presses against the detection element of the workpiece to be detected, the detection element provides a reaction force for the detection movable component 22, and the detection movable component 22 moves relative to the mounting base 21 in a direction away from the detection element. The detection member 23 can detect the position of the detection movable component 22, and judge whether the detection element of the workpiece to be detected is missing or over-installed according to the position change of the detection movable component 22.
