Description

Technical Field

[0001] This application belongs to the field of electronic pen technology, specifically relating to an electronic pen assembly device and an electronic pen. Background Technology

[0002] An electronic pen is a device that enables human-computer interaction and can be used in paperless office scenarios such as signing and authorization. An electronic pen mainly consists of a hollow shell and a pen refill embedded in the shell. Some electronic pens have markings on the pen refill and display slots or holes on the shell to ensure that the markings are exposed through the slots or holes after the electronic pen is assembled.

[0003] In related technologies, the assembly of the electronic pen is often done manually. This involves a technician holding the pen tip and the outer casing, visually observing and manually adjusting their relative positions to align the display slot or display hole with the markings on the pen tip. The pen tip is then pushed into the outer casing along its length to complete the assembly of the electronic pen.

[0004] However, assembling electronic pens by hand requires a high level of skill from the technicians. It takes time and effort for the technicians to ensure that the markings are aligned in the correct position, resulting in low assembly efficiency. At the same time, the markings are prone to deviating from the correct position, making it difficult to guarantee the consistency of the assembly results. Utility Model Content

[0005] This application aims to provide an assembly device and an electronic pen for electronic pens, which at least solves the problem of poor assembly efficiency and assembly effect caused by hand-held operation in the prior art.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application provide an assembly apparatus for an electronic pen, the assembly apparatus comprising:

[0008] First clamping mechanism, second clamping mechanism, first driving component, and second driving component;

[0009] The first clamping mechanism includes a limiting groove that matches the size of the electronic pen's casing, one end of which passes through the first clamping mechanism to form an opening facing the second clamping mechanism;

[0010] The second clamping mechanism includes a clamping part for clamping the pen refill of the electronic pen;

[0011] The second clamping mechanism is connected to the first driving member and the second driving member respectively; under the action of the first driving member, the clamping part clamps the pen refill and rotates it around the axis; under the action of the second driving member, the pen refill is pushed to move along the axis toward the opening.

[0012] Optionally, the clamping part of the second clamping mechanism includes a first clamping arm, a clamping base, and an electronic lock;

[0013] One end of the first clamping arm is movably connected to the clamping base, and the other end of the first clamping arm is provided with a first buckle. The first buckle engages when the other end of the first clamping arm contacts the clamping base to clamp the pen refill. When the first buckle is not engaged, the electronic lock prevents the clamping part from rotating around the axis.

[0014] Optionally, the first driving component includes an input shaft and an output shaft, wherein the rotational speed of the input shaft is greater than or equal to the rotational speed of the output shaft, and the output shaft is coaxially connected to the clamping part.

[0015] Optionally, the assembly device for the electronic pen may further include a locking mechanism;

[0016] The locking mechanism includes a second clamping arm, a third clamping arm, and a third driving member. The second clamping arm and the third clamping arm are located on opposite sides of the radial direction of the bearing. Under the action of the third driving member, the second clamping arm and the third clamping arm move closer to each other and clamp the output shaft to prevent the output shaft from rotating.

[0017] Optionally, the first driving component further includes a manual rotating wheel; the manual rotating wheel, the input shaft, and the output shaft are sequentially fixedly connected with the axis as a common rotating axis.

[0018] Optionally, the electronic pen assembly device further includes a first push block, one end of which is connected to the output end of the second drive member, and the other end of which is mounted on the clamping base of the clamping part and is provided with a soft contact part.

[0019] Under the action of the second driving member, the first push block moves along the axis and pushes the pen refill along the axis toward the opening of the limiting groove when the soft contact part contacts the pen refill.

[0020] Optionally, the assembly device for the electronic pen further includes a rotary reset mechanism, which includes a fourth driving member and a second pusher.

[0021] Under the action of the fourth driving member, the second push block moves in a direction perpendicular to the axis and pushes the bottom surface of the clamping base so that the clamping part rotates around the axis, and the bottom surface of the clamping base is parallel to the axis.

[0022] Optionally, the assembly device for the electronic pen further includes an imaging module, which includes a bracket, a lens, and a display panel;

[0023] The lens and the display panel are mounted on the bracket; the lens faces the side of the limiting groove near the opening, the display panel is used to magnify and display the image captured by the lens, and the display panel is provided with a positioning mark.

[0024] Optionally, the first clamping mechanism includes a table and a cover, a second buckle is provided on the table, and a limiting groove is provided on the table; when the cover is closed on the table, the second buckle is engaged, so that the cover presses against the electronic pen placed in the limiting groove.

[0025] Secondly, embodiments of this application provide an electronic pen, which is assembled using an assembly apparatus for an electronic pen as described in any of the first aspects;

[0026] The electronic pen includes a hollow outer shell and a pen refill fitted inside the outer shell. The inner diameter of a first port of the outer shell is larger than the maximum diameter of the pen refill. The outer shell includes a cutout near the first port. The inner diameter of a second port of the outer shell is smaller than the maximum diameter of the pen refill. The surface of the pen refill includes a marking portion. The pen refill extends into the interior of the outer shell from the first port. The pen refill rotates relative to the outer shell to align the marking portion with the cutout portion.

[0027] In this embodiment, the limiting groove of the first clamping mechanism holds the outer shell of the electronic pen, and the clamping part of the second clamping mechanism clamps the pen refill of the electronic pen. This mechanical structure achieves the fixation and pre-positioning of the two main components, the outer shell and the pen refill, avoiding uneven force application or inaccurate positioning during manual assembly. The position of the pen refill relative to the outer shell is controlled by the first and second driving components. The first driving component controls the rotation of the pen refill to ensure it can rotate to the desired position relative to the outer shell. The second driving component pushes the pen refill so that it can be fully inserted into the outer shell after rotating to the desired position, thus completing the assembly of the electronic pen. By replacing manual operation with a mechanical structure, the operational requirements for relevant technicians are reduced, the assembly operation of the electronic pen is simplified, and assembly efficiency is improved. The action of the first and second driving components, in conjunction with the first and second clamping mechanisms, ensures stable force on the outer shell and the pen refill during the assembly process, thereby avoiding additional travel during the relative movement of the outer shell and the pen refill, improving assembly accuracy, and ultimately ensuring the assembly effect.

Detailed Implementation

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0043] Combined with reference Figure 1 and Figure 2 , Figure 1 This is an isometric structural diagram of the electronic pen assembly device provided in the embodiments of this application. Figure 2 For Figure 1 An enlarged structural schematic diagram of region A; the assembly device for the electronic pen may include: a first clamping mechanism 20, a second clamping mechanism 30, a first driving component 41, and a second driving component (…). Figure 1 , Figure 2 (Not shown in the image). The first clamping mechanism 20 includes a limiting groove 211 that matches the size of the outer shell 51 of the electronic pen 50. One end of the limiting groove 211 passes through the first clamping mechanism 20, forming an opening 2111 facing the second clamping mechanism 30. The second clamping mechanism 30 includes a clamping part 31 for clamping the pen refill 52 of the electronic pen 50. The second clamping mechanism 30 is connected to the first driving member 41 and the second driving member respectively. Under the action of the first driving member 41, the clamping part 31 clamps the pen refill 52 and rotates it around the axis 60. Under the action of the second driving member, the pen refill 52 is pushed to move along the axis 60 toward the opening 2111.

[0044] The first clamping mechanism 20, the second clamping mechanism 30, the first driving member 41, and the second driving member can be disposed on the main body 10 of the electronic pen assembly device. The first clamping mechanism 20 and the second clamping mechanism 30 can be disposed on the same surface of the main body 10, while the first driving member 41 and the second driving member can be disposed on the surface or inside the main body 10, respectively. Since the first driving member 41 and the second driving member can be used to adjust the relative position of the pen tip 52 and the outer shell 51, the first driving member 41 and the second driving member can be collectively referred to as the adjustment driving member 40 to distinguish them from other driving members in the electronic pen assembly device.

[0045] In this embodiment, a first clamping mechanism 20 is used to fix the outer shell 51 of the electronic pen 50, and a second clamping mechanism 30 is used to securely clamp the pen refill 52 of the electronic pen 50. By operating the first driving member 41, the pen refill 52 located on the clamping part 31 of the second clamping mechanism 30 rotates around the axis 60. The length extension direction of the limiting groove 211 of the first clamping mechanism 20 is located on the same axis 60 as the pen refill 52 located on the clamping part 31, allowing the pen refill 52 to rotate coaxially relative to the outer shell 51, thereby allowing the pen refill 52 to rotate to the desired position. The desired position here represents an intermediate state of the positional relationship between the pen tip 52 and the outer shell 51 during the assembly process. When the pen tip 52 is in the desired position, the second driving component pushes the pen tip 52 into the outer shell 51 along the length direction of the axis 60, thereby obtaining an electronic pen 50 that is fully assembled and whose pen tip 52 and outer shell 51 meet the preset target positional relationship. The preset target positional relationship can mean that when the electronic pen 50 is assembled, the marking part in the pen tip 52 can be exposed through the display hole or slot of the outer shell 51 without being blocked by other parts of the outer shell 51.

[0046] For example, the first driving component 41 may include a manual rotating wheel; the diameter of the manual rotating wheel may be greater than the maximum diameter of the pen refill, and a person skilled in the art can control the position of the pen refill 52 relative to the outer casing 51 by rotating the manual rotating wheel; since the diameter of the manual rotating wheel is greater than the maximum diameter of the pen refill 52, when the rotational angular velocities of the manual rotating wheel and the pen refill 52 are the same, the linear velocity of the pen refill 52 will be less than the linear velocity of the edge of the manual rotating wheel, so that the rotational stroke of the edge of the manual rotating wheel around the axis 60 is greater than the rotational stroke of the pen refill 52 around the axis 60, thereby realizing the fine-tuning rotation of the pen refill 52 while rotating the manual rotating wheel.

[0047] For example, the second driving component may include a cylinder or a motor; by pushing the pen tip 52 through the second driving component, the pen tip 52 is stably subjected to the thrust from the axial direction of the axis 60, avoiding uneven force on the pen tip 52 in the radial direction of the axis 60, so that the pen tip 52 can be directly pushed into the housing 51 of the electronic pen 50 without causing the pen tip 52 to rotate additionally, thereby avoiding unnecessary travel of the pen tip 52 in the circumferential direction of the axis 60.

[0048] In this embodiment, the clamping part 31 clamps the pen refill 52 and rotates it around the axis 60 in a first circumferential direction. The first circumferential direction can refer to the direction from the initial position of the pen refill 52 to the desired position of the pen refill 52. When viewed from the opening 2111 of the limiting groove 211 towards the clamping part 31, the first circumferential direction can be clockwise or counterclockwise. It can be understood that the rotation of the pen refill 52 from the initial position to the desired position can be the result of multiple adjustments by the first driving member 41. That is, when viewed from the opening 2111 of the limiting groove 211 towards the clamping part 31, the pen refill 52 has undergone multiple clockwise and counterclockwise rotations before finally reaching the desired position.

[0049] In related technologies, it is difficult to ensure that the hand applies force smoothly and evenly to the pen refill 52 and the outer shell 51, thus making it difficult to ensure the relative stability of the pen refill 52 and the outer shell 51 during the assembly process. However, in this embodiment, the outer shell 51 is fixed by the first clamping mechanism 20, the clamping part 31 of the second clamping mechanism ensures the stability of the rotation of the pen refill 52, and the second driving member ensures the stability of the linear movement of the pen refill 52. This ensures the stability of the assembly process of the electronic pen 50, avoids unnecessary stroke of the pen refill 52 during the movement, and ensures the assembly effect of the electronic pen 50.

[0050] In this embodiment, the limiting groove 211 of the first clamping mechanism 20 holds the outer shell 51 of the electronic pen, and the clamping part 31 of the second clamping mechanism 30 clamps the pen refill 52 of the electronic pen. This mechanical structure achieves the fixation and pre-positioning of the two main components, the outer shell 51 and the pen refill 52, avoiding uneven force or inaccurate positioning during assembly. The position of the pen refill relative to the outer shell is controlled by the first driving member 41 and the second driving member 42. The first driving member 41 controls the rotation of the pen refill 52 to ensure that the pen refill 52 can rotate to the desired position relative to the outer shell 51. Two driving components push the pen tip 52, allowing it to be fully inserted into the housing 51 after rotating to the desired position, thus completing the assembly of the electronic pen. By replacing manual operation with mechanical structure, the operational requirements for relevant technicians are reduced, the assembly operation of the electronic pen is simplified, and the assembly efficiency is improved. Through the action of the first driving component 41 and the second driving component, in conjunction with the first clamping mechanism and the second clamping mechanism, the stable force on the housing and pen tip is ensured during the assembly of the electronic pen, thereby avoiding additional travel during the relative movement of the housing 51 and the pen tip 52, improving assembly accuracy, and thus ensuring the assembly effect.

[0051] Optional, in conjunction with reference Figure 2 and Figure 3 ,in Figure 3 for Figure 1 Another enlarged structural diagram of region A in the middle. Figure 2 and Figure 3 The following are axonometric views of region A from different viewing directions. The clamping part 31 of the second clamping mechanism 30 includes a first clamping arm 311, a clamping base 312, and an electronic lock. One end of the first clamping arm 311 is movably connected to the clamping base 312, and the other end of the first clamping arm 311 is provided with a first buckle 3111. When the other end of the first clamping arm 311 is in contact with the clamping base 312, the first buckle 3111 engages to clamp the pen refill 52. When the first buckle 3111 is not engaged, the electronic lock prevents the clamping part 31 from rotating around the axis 60.

[0052] The clamping part 31 in the second clamping mechanism 30 may include a first clamping arm 311 and a clamping base 312. One end of the first clamping arm 311 can be hinged to the clamping base 312, allowing the first clamping arm 311 to rotate around the hinge center, thereby allowing the other end of the first clamping arm 311 to move closer to or further away from the clamping base 312. When the first clamping arm 311 is fastened to the clamping base 312 by the first buckle 3111 at the other end, a gap matching the radial dimension of the pen refill 52 of the electronic pen 50 will be left between the first clamping arm 311 and the clamping base 312. The clamping part 31 can securely hold the pen refill 52 without damaging it. An electronic lock can be installed in the clamping part 31. By engaging or disengaging the first latch 3111, the circuit in the electronic lock can be turned on or off. When the first latch 3111 is not engaged, the circuit in the electronic lock is off. At this time, the electronic lock will lock the clamping part 31, preventing it from rotating. This prevents the clamping part 31 from rotating when the pen refill 52 is not being held or is not securely held, thus preventing abnormal start-up and achieving a foolproof effect.

[0053] After the clamping part 31 firmly clamps the pen refill 52, the length direction of the pen refill 52 and the length extension direction of the limiting groove 211 will both be located on the axis 60, so that after the pen refill 52 is rotated to the desired position, it can be pushed into the outer shell 51 located on the limiting groove 211 along the axis 60.

[0054] When the first clamping arm 311 and the clamping base 312 of the clamping part 31 clamp the pen refill 52 and the first buckle 3111 is engaged, the clamping part 31 can rotate around the axis 60 to drive the clamped pen refill 52 to rotate around the axis 60, thereby achieving the effect of adjusting the relative position of the pen refill 52 and the pen shell located in the limiting groove 211.

[0055] Optional, refer to Figure 4 , Figure 4 Examples of this application Figure 1 A top view of the provided electronic pen assembly device is provided for easy observation. Figure 4 The image module 90 that obstructs the clamping part 31 from the top-down view is omitted; the first driving member 41 includes an input shaft 411 and an output shaft (not shown in the figure 4), the rotational speed of the input shaft 411 is greater than or equal to the rotational speed of the output shaft, and the output shaft is coaxially connected to the clamping part 31.

[0056] The first driving member 41 may include an input shaft 411 and an output shaft. The input shaft 411 is used to receive input excitation for rotating the clamping part 31. The input excitation may include torque provided by a motor, cylinder, or hand. That is, the input shaft 411 may be connected to the output end of a motor or cylinder or a manual force application component. The input shaft 411 may be driven or fixedly connected to one end of the output shaft. The other end of the output shaft is fixed and coaxially connected to the clamping part 31, so that the input excitation can be transmitted to the clamping part 31 to drive the clamping part 31 to rotate.

[0057] The input shaft 411 can be connected to the output shaft so that the rotational speed of the input shaft 411 is greater than that of the output shaft. That is, a speed reduction effect is achieved through the input shaft 411 to the output shaft. When the torque received by the input shaft 411 comes from a motor with a higher rotational speed, the rotational speed of the clamping part 31 can be controlled to be lower than that of the motor through the input shaft 411 to the output shaft, so as to facilitate the observation and fine adjustment of the rotation of the clamping part 31.

[0058] The input shaft 411 can also be fixedly connected coaxially with the output shaft. In this case, the rotational speed of the input shaft 411 is equal to the rotational speed of the output shaft. When the torque received by the input shaft 411 comes from manual operation, the diameter of the input shaft 411 can be set to be larger than the diameter of the pen tip 52, so that the linear velocity of the surface of the input shaft 411 is greater than the linear velocity of the surface of the pen tip 52. At this time, when rotating by the same angle, the pen tip will rotate a shorter stroke relative to the input shaft, thereby enabling fine adjustment of the rotation of the clamping part 31.

[0059] Optional, in conjunction with reference Figure 3 , Figure 5 and Figure 6 ,in Figure 5 for Figure 4 A schematic diagram of the cross-sectional structure along BB. Figure 6 Then it is Figure 5 An enlarged structural diagram of region C; the electronic pen assembly device also includes a locking mechanism 70; the locking mechanism 70 includes a second clamping arm 71, a third clamping arm 72 and a third driving member 73. The second clamping arm 71 and the third clamping arm 72 are located on opposite sides of the radial direction of the output shaft. Under the action of the third driving member 73, the second clamping arm 71 and the third clamping arm 72 move closer to each other and clamp the output shaft to prevent the output shaft from rotating.

[0060] Reference Figure 4 A locking switch 731 can be provided on the main body 10 of the device to manually control the operation of the third drive member 73, thereby realizing manual control of whether the locking mechanism 70 is working. For example, the locking switch 731 can be set as a button.

[0061] After rotating the clamping part 31 to rotate the pen refill 52 to the desired position, the clamping part 31 can be locked by the locking mechanism 70 to prevent further rotation of the clamping part 31 during subsequent processes. Specifically, a bearing 43 is first sleeved on the output shaft. The bearing 43 is divided into a movable part 431 and a fixed part 432. The movable part 431 is sleeved on the output shaft to realize the mating connection between the output shaft and the bearing 43. The fixed part 432 is used to fix the bearing 43 to the main body 10 of the device. The length of the movable part 431 in the direction parallel to the axis 60 is greater than the length of the fixed part 432 in the direction parallel to the axis 60, so that part of the movable part 431 is exposed outside the fixed part 432. On opposite sides of the movable part 431 of the bearing 43 in the radial direction, a second clamping arm 71 and a third clamping arm 72 are respectively provided. The three clamping arms 72 are powered by the third driving member 73. The second clamping arm 71 and the third clamping arm 72 can move closer to or further away from each other. When the second clamping arm 71 and the third clamping arm 72 simultaneously clamp the part of the movable part 431 exposed outside the fixed part 432, they will prevent the movable part 431 of the bearing 43 from continuing to rotate, thereby preventing the output shaft from rotating and thus making the clamping part 31 unable to rotate. It can be understood that the locking mechanism 70 indirectly achieves the clamping and locking of the output shaft through the second clamping arm 71, the third clamping arm 72 and the bearing 43. For example, the third driving member 73 may include a cylinder or a motor. According to the spatial arrangement requirements, the third driving member 73 may be fixedly installed on the surface of the device body 10 or inside the device body 10.

[0062] Optional, in conjunction with reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The first driving component 41 also includes a manual rotating wheel 412; the manual rotating wheel 412, the input shaft 411 and the output shaft (not shown in the above figure) are sequentially fixedly connected with the axis 60 as a common rotating axis.

[0063] The first driving component 41 may include a manual rotating wheel 412. In the embodiment shown in this application, the torque input by the hand is received by the manual rotating wheel 412 and then transmitted to the clamping part 31 in sequence through the coaxially arranged input shaft 411 and output shaft. This allows manual operation of the clamping part 31 to rotate, thereby driving the pen refill 52 to rotate. It should be noted that when the manual rotating wheel 412 is connected to one end of the input shaft 411, the manual rotating wheel 412 will receive the input excitation, and the function of the input shaft 411 will become the transmission of torque. At the same time, the diameter of the rotating handwheel can be set to be larger than the maximum diameter of the pen refill 52. When rotating coaxially, the linear velocity of the edge of the rotating handwheel is greater than the linear velocity of the pen refill 52, ensuring that the first driving component 41 can still achieve the effect of fine-tuning the rotation.

[0064] Optionally, the electronic pen assembly device may further include: a first push block 421; one end of the first push block 421 extends and is connected to the output end of the second drive member 42, and the other end of the first push block 421 is mounted on the clamping base 312 of the clamping part 31 and is provided with a soft contact part 4211; under the action of the second drive member 42, the first push block 421 moves along the axis 60, and when the soft contact part 4211 contacts the pen core 52, it pushes the pen core 52 to move along the axis 60 toward the opening 2111 of the limiting groove 211.

[0065] Reference Figure 5 , Figure 5 The diagram shows a second drive unit 42 for propelling the pen refill 52 in a linear motion and a first pusher 421 that cooperates with it. The second drive unit 42 can be housed inside the main body 10 of the device, thereby improving the space utilization of the device. The second drive unit 42 is connected to the first pusher 421 via a transmission connection, allowing the first pusher 421 to move linearly in a direction X parallel to the axis 60 under the action of the second drive unit 42. Further reference... Figure 2 and Figure 7 ,in Figure 7 for Figure 2 The diagram shows the structure of the first push block 421. The first push block 421 is located on the clamping base 312 at one end outside the main body 10 of the device. It is also provided with a soft contact part 4211. When the first push block 421 moves linearly under the action of the second driving member 42, the soft contact part 4211 will gradually approach the pen refill 52 until it touches the pen refill 52. When the first clamping arm 311 of the clamping part 31 is open, the pen refill 52 can be pushed by the soft contact part 4211 and moved along the axial direction of the axis 60, so that the pen refill 52 is pushed into the outer shell 51 of the electronic pen 50 fixed at the other end of the axis 60, thereby completing the assembly of the electronic pen 50.

[0066] For example, the second driving element 42 may include a cylinder or a motor; a push switch 422 may be provided on the main body of the device to control the start of the second driving element 42, so as to realize manual control of the second driving element 42. For example, the push switch 422 may be set as a button.

[0067] The size of the soft contact portion 4211 matches the cross-sectional size of the pen refill 52, and it is made of a soft material, such as rubber, silicone or other elastic materials. On the one hand, it increases the contact area when the soft contact portion 4211 abuts against the pen refill 52, thereby increasing the friction between the soft contact portion 4211 and the pen refill 52 and preventing the pen refill 52 from generating additional rotation when it is pushed. On the other hand, the soft contact portion 4211 can protect the end of the pen refill 52 during the process of the first pusher 421 pushing the pen refill 52, preventing it from being damaged by impact.

[0068] It should be noted that after the first pusher 421 pushes the pen refill 52 completely into the pen shell, the second drive unit 42 can be controlled to reverse so that the first pusher 421 returns to its initial position so that the second clamping mechanism can receive the next pen refill 52 to be assembled.

[0069] Optional, in conjunction with reference Figure 3 and Figure 8 ,in Figure 8 Another isometric schematic diagram of the assembly apparatus for the electronic pen provided in the embodiments of this application, relative to Figure 1 , Figure 3 The main body 10 and camera module are omitted; the electronic pen assembly device also includes a rotary reset mechanism 80, which includes a fourth drive member 81 and a second push block 82; under the action of the fourth drive member 81, the second push block 82 moves in a direction perpendicular to the axis 60 and pushes the bottom surface of the clamping base 312 so that the clamping part 31 rotates around the axis 60; the bottom surface of the clamping base 312 is parallel to the axis.

[0070] In this embodiment, a rotation reset mechanism 80 is provided to restore the clamping part 31 to its initial position after the electronic pen 50 is assembled; referring to the reference Figure 3 and Figure 8 A second push block 82 is provided below the clamping base 312. Through the fourth driving member 81, the second push block 82 can move in a direction perpendicular to the axis 60 (parallel to the axis 60). Figure 8 The clamping base 312 moves linearly in the Y direction. The bottom surface of the clamping base 312 can be a plane and parallel to the axis 60. When the clamping part 31 is in the initial position, the bottom surface is perpendicular to the moving direction of the second push block 82. When the first circumferential rotation is performed, the bottom surface rotates around the axis 60, causing one side of the bottom surface to press down on the second push block 82. When the fourth driving member 81 is activated, the second push block 82 pushes up the side of the bottom surface of the clamping base 312 that was pressing down on the second push block 82, causing the clamping base 312 to rotate around the axis 60 in the second circumferential direction opposite to the first circumferential direction. This makes the bottom surface of the clamping base 312 parallel to the moving direction of the second push block 82 again, achieving the purpose of resetting.

[0071] For example, the fourth driving element 81 may include a cylinder or a motor; a reset switch 811 may be provided on the main body of the device to control the start of the fourth driving element 81, so as to realize manual control of the fourth driving element 81. For example, the reset switch 811 may be set as a button.

[0072] Optional, in conjunction with reference Figure 1 and Figure 2The electronic pen assembly device also includes an image module 90, which includes a bracket 91, a lens 92, and a display panel 93. The lens 92 and the display panel 93 are mounted on the bracket 91. The lens 92 faces the side of the limiting groove 211 near the opening 2111. The display panel 93 is used to magnify and display the image captured by the lens 92. A positioning mark 931 is provided on the display panel 93.

[0073] An image module 90 is included in the electronic pen assembly device to acquire and magnify real-time images of the pen tip 52 and the outer casing 51. The image module 90 may include a lens 92 for capturing images and a display panel 93 for magnifying the display. The lens 92 and display panel 93 can be sequentially mounted on a support 91. The height of the display panel 93 can be adjusted along the length of the support 91 to match the line-of-sight position of the technician. The image module 90 may also include a charge-coupled device (CCD), which converts the light signal captured by the lens 92 into an electrical signal for transmission to the display panel 93 for display. Further reference... Figure 9 , Figure 9 Examples of this application Figure 1 The provided electronic pen assembly device includes a schematic diagram of the display panel 93 of the image module 90. The surface of the display panel 93 is provided with parallel and spaced linear positioning marks 931. By pre-setting the distance between the lens 92 and the first clamping mechanism 20, the image of the edge of the outer shell 51 or the pen tip 52 in the image displayed on the display panel 93 coincides with the linear positioning marks 931. This helps relevant technicians to rotate and fine-tune the position of the pen tip 52 relative to the outer shell 51 according to the image, ensuring the final assembly effect of the electronic pen 50.

[0074] Optional, in conjunction with reference Figure 1 , Figure 2 and Figure 3 The first clamping mechanism 20 includes a table 21 and a cover 22. A second buckle 221 is provided on the table 21, and a limiting groove 211 is provided on the table 21. When the cover 22 is closed on the table 21, the second buckle 221 is engaged, so that the cover 22 presses the electronic pen 50 placed in the limiting groove 211.

[0075] The first clamping mechanism 20 for fixing the outer shell 51 of the electronic pen 50 may include a table 21 and a cover 22. The table 21 is used to open a limiting groove 211 for placing the outer shell 51 of the electronic pen 50. The cover 22 is provided on the table 21. When the cover 22 is closed, the cover 22 and the table 21 can be pressed together by fastening the second buckle 221 to fix the outer shell 51. The first clamping mechanism 20 can also use an electronic lock, and the closing and closing of the electronic lock can be controlled by the engagement and disengagement of the second latch 221. When the second latch 221 is engaged, the electronic lock is activated, indicating that the pen shell has been fixed. If the first latch 3111 of the clamping part 31 is also engaged, it indicates that the pen refill 52 is also firmly clamped, and the assembly of the electronic pen 50 can begin. If at least one of the first latch 3111 or the second latch 221 is in an open state, the corresponding electronic lock is in a closed state, indicating that at least some parts of the electronic pen 50 are not firmly placed on the clamp. At this time, the first clamping mechanism 20 and the second clamping mechanism 30 need to be checked to ensure that the outer shell 51 and the pen refill 52 are clamped.

[0076] Reference Figure 10 This is an embodiment of the present application. Figure 1 The above-view structural diagram of the electronic pen 50 is shown. This application embodiment also provides an electronic pen 50, which can be assembled by the above-described electronic pen assembly device. The electronic pen 50 includes a hollow outer shell 51 and a pen core 52 assembled inside the outer shell 51. The inner diameter of the first port 511 of the outer shell 51 is larger than the maximum diameter of the pen core 52. The outer shell 51 includes a hollow portion 513 near the first port 511. The inner diameter of the second port 512 of the outer shell 51 is smaller than the maximum diameter of the pen core 52. The surface of the pen core 52 includes a marking portion 521. The pen core 52 extends into the interior of the outer shell 51 from the first port 511. The pen core 52 rotates relative to the outer shell 51 so that the marking portion 521 is aligned with the hollow portion 513.

[0077] The electronic pen assembly apparatus provided in this application embodiment can be used to assemble an electronic pen 50 having the above-mentioned features; the electronic pen 50 includes a pen core 52 and a housing 51. The pen core 52 has an marking portion 521 on its surface. The pen core 52 can extend into the housing 51 through a first port 511 and be fixed inside the housing 51 by adhesive or snap-fit. One end of the pen core 52 extending into the housing 51 will protrude from a second port 512 of the housing 51 to achieve the touch control effect of the electronic pen 50; the housing 51 is positioned near the first port 511. The device is provided with a cutout portion 513 for displaying the marking portion 521 on the pen refill 52 after it is installed inside the housing 51. The assembly device of the electronic pen adjusts the relative position of the marking portion 521 and the cutout portion 513 by causing the pen refill 52 and the housing 51 to rotate relative to each other on the same axis 60, so that the marking portion 521 can be aligned with the cutout portion 513. Then the pen refill 52 is pushed into the housing 51, so that after the assembly of the electronic pen 50 is completed, the marking portion 521 of the pen refill 52 is just exposed from the cutout portion 513 of the housing 51.

[0078] In this embodiment, the limiting groove of the first clamping mechanism holds the outer shell of the electronic pen, and the clamping part of the second clamping mechanism clamps the pen refill of the electronic pen. The limiting groove and the clamping part are located on the same axis, thereby achieving the fixation and pre-positioning of the two major components of the electronic pen through a mechanical structure, avoiding manual assembly of the outer shell and pen refill. The position of the pen refill relative to the outer shell is controlled by adjusting the driving component, wherein the first driving component controls the rotation of the pen refill, ensuring that the pen refill can rotate to the required position relative to the outer shell. The second driving component pushes the first push block, thereby pushing the pen refill, so that after the pen refill rotates to the required position, it can be completely inserted into the outer shell, thus completing the assembly of the electronic pen. By replacing manual operation with mechanical structure, the operational requirements for relevant technicians are reduced, the assembly operation of the electronic pen is simplified, and the assembly efficiency is improved. By adjusting the action of the driving component, in conjunction with the first and second clamping mechanisms, the stable force on the outer shell and pen refill is ensured during the assembly of the electronic pen, thereby avoiding additional travel during the relative movement of the outer shell and pen refill, and thus ensuring the assembly effect.
