Description
Technical Field
[0001] This utility model relates to the field of electronic pen assembly technology, and more specifically to an electronic pen assembly device. Background Technology
[0002] An electronic pen consists of a pen casing and a refill inside the casing. To reduce the movement of the refill inside the casing, the outer circumference of the refill is close to the inner cavity size of the casing, making it difficult to install the refill into the casing. At the same time, interference foam FPC (Flexible Printed Circuit) is attached to the outer surface of the refill. During the process of installing the refill into the casing, the FPC is at risk of curling and damage, which further increases the assembly difficulty of the electronic pen.
[0003] In related technologies, the assembly of pen shell and pen refill is carried out manually using a small pressure bar tool. The FPC is prone to interference with the pen shell, which can cause the FPC to curl or even be damaged. Furthermore, the assembly accuracy and consistency of the pen refill and pen shell cannot be guaranteed. Since the positioning between the pen shell and pen refill needs to be manually controlled, the production efficiency is also low. Utility Model Content
[0004] In view of this, the present invention provides an electronic pen assembly device to solve the problems of potential curling and damage of FPC, inability to guarantee assembly accuracy and consistency, and low production efficiency during the assembly of electronic pen refills and shells.
[0005] This utility model provides an electronic pen assembly device, comprising: a body; a guide block, detachably disposed on the body and having a guide hole, the guide hole penetrating the guide block, forming a pen shell insertion port at one end of the guide block and a pen refill insertion port at the other end of the guide block; a sliding module, including a slide rail and a slider, the slide rail being disposed on the body, the slider being slidably disposed on the slide rail and sliding along the axial direction of the guide hole; a pressure detection element disposed on the side of the slider facing the guide block; and a pen refill pusher disposed on the side of the pressure detection element facing the guide block.
[0006] Beneficial Effects: This electronic pen assembly device uses a guide block to pre-position the pen shell and pen refill, and employs a refill pusher to insert the pen refill into the pen shell. No manual control of the relative position of the pen shell and pen refill is required. During assembly, the pen shell and pen refill experience only axial thrust applied by the refill pusher along the guide hole, with almost no deflection force. This improves the installation accuracy and consistency between the pen shell and pen refill, resulting in high production efficiency. Furthermore, it reduces the likelihood of FPC interference with the pen shell, decreasing the probability of FPC curling and damage, thus improving the yield rate of the electronic pen. By incorporating a pressure detection component, the pressure of the refill pusher can be monitored to prevent abnormal thrust from damaging the pen refill or pen shell, further improving product yield. Additionally, since the guide block is detachable from the main body, it facilitates the insertion of the pen shell and pen refill into the guide hole, improving the assembly efficiency of the electronic pen.
[0007] In one optional embodiment, the push pen refill component has a guide groove on the side facing the guide block, and the cross-sectional area of the guide groove gradually increases towards the guide block.
[0008] Beneficial effects: When the pen refill pusher moves toward the guide block, the pen refill is easily inserted into the guide groove. As the pen refill is inserted into the bottom of the guide groove, the positioning between the pen refill pusher and the pen refill is achieved, so that the central axis of the guide groove of the pen refill pusher and the central axis of the pen refill coincide or approximately coincide, resulting in a good fit between the pen refill pusher and the pen refill.
[0009] In one optional embodiment, the electronic pen assembly device further includes a limiting block disposed on the body and located between the slider and the guide block, wherein the slider can abut against the limiting block within its sliding stroke.
[0010] Beneficial effects: The limiting block can limit the maximum depth of the pen refill inserted into the pen case, preventing the pen refill from being inserted too deeply into the pen case. This reduces the probability of damage to the pen refill and pen case, and also improves installation accuracy and consistency.
[0011] In one optional embodiment, the guide hole includes a pen shell insertion segment and a pen refill insertion segment, the pen shell insertion segment communicating with the pen shell socket, and the pen refill insertion segment communicating between the pen shell insertion segment and the pen refill socket; on a plane perpendicular to the axis of the guide hole, the projection of the pen refill insertion segment lies within the projection of the pen shell insertion segment.
[0012] Beneficial effects: A step can be formed between the refill segment and the shell segment. When the shell is inserted into the shell segment from the shell insertion port, the shell abuts against the step between the refill and shell segments, thus determining the relative position between the shell and the guide block. When the refill is inserted into the refill segment from the refill insertion port, due to its small cross-sectional area, it can pass through the refill segment and into the shell. Furthermore, the assembled refill and shell can be removed from the shell insertion port.
[0013] In one alternative embodiment, the cross-sectional area of the pen refill segment gradually increases toward the pen refill opening.
[0014] Beneficial effects: It facilitates the insertion of the pen refill into the pen refill insert and reduces friction between the pen refill and the inner wall of the pen refill insert, thereby reducing the probability of FPC curling and damage and improving the yield rate of electronic pens.
[0015] In one alternative embodiment, the inner circumferential surface of the pen casing segment is provided with a positioning protrusion; at least a portion of the inner circumferential surface of the pen refill segment is constructed as a positioning plane.
[0016] Beneficial effects: The outer circumferential surface of the pen shell has a notch, and the positioning protrusion inside the pen shell insertion section mates with the notch to position the pen shell and guide block circumferentially within the guide hole, preventing relative rotation between the guide block and the pen shell. The positioning plane enables the guide block and pen refill to be positioned circumferentially within the guide hole, preventing relative rotation between them, thereby determining the relative position of the pen shell and pen refill circumferentially within the guide hole and improving installation accuracy.
[0017] In one optional embodiment, the electronic pen assembly device further includes: a push plate slidably disposed on the body; a slide rod connected to the push plate, and the slider slidably connected to the slide rod; and an elastic element sleeved on the slide rod and located between the push plate and the slider.
[0018] Beneficial effects: When the slider comes into contact with the pen refill, and the slider pushes the pen refill to move, the elastic element can undergo elastic deformation to absorb part of the pressure between the slider and the pen refill, thus preventing the pen refill and pen shell from being damaged due to excessive force.
[0019] In one optional embodiment, the electronic pen assembly device further includes: a driver, comprising a driver body and a driver rod, the driver body being disposed inside the body, and the driver rod being retractably connected to the driver body; the sliding module and the sliding rod being disposed outside the body, the body having a through hole, the push plate being slidably disposed through the through hole and connected to the driver rod.
[0020] Beneficial effects: By incorporating a driver that allows the push plate to slide relative to the body, automatic assembly between the pen refill and the pen shell is achieved, eliminating the need for manual movement of the slider and increasing automation. Since the driver is located inside the body, its exposed area is reduced, preventing dust and other impurities from affecting its operation. Furthermore, the air tubing connected to the driver can be concealed within the body, improving the neatness of the piping layout and facilitating the normal operation of the electronic pen assembly device. Additionally, the through-hole design allows the push plate to connect to both the driver and the sliding module while simultaneously enabling movement of the push plate relative to the body.
[0021] In one optional embodiment, the electronic pen assembly device further includes: a mounting base disposed on the body and having a mounting groove, wherein the guide block is disposed in the mounting groove; and a positioning base disposed on the body and located on the side of the mounting base opposite to the pen refill component, wherein the positioning base has a pen shell positioning groove, wherein the side of the pen shell positioning groove facing the mounting base has a pen shell through hole, and wherein the side of the pen shell positioning groove opposite to the mounting base has a pen shell stop portion.
[0022] Beneficial effects: The mounting slot can fix the relative position between the mounting base and the guide block, thereby fixing the relative position between the guide block and the body. The pen shell positioning slot can fix the relative position between the pen shell and the positioning base. Since the pen shell is placed into the pen shell mounting slot after the pen shell and guide block are fixed, the pen shell through hole can avoid interference between the pen shell and the side wall of the pen shell mounting slot. Furthermore, the end of the pen shell away from the guide block abuts against the pen shell stop. When the pen refill pusher moves the pen refill within the guide block, and when the pen refill is inserted into the pen shell, the guide block and pen shell will not move relative to the body, thus improving the installation accuracy and efficiency of the pen shell and pen refill.
[0023] In one alternative embodiment, the lowest point of the guide hole is higher than the sidewall of the mounting groove.
[0024] Beneficial effects: It can avoid interference between the pen shell and pen refill inserted into the guide hole and the side wall of the mounting slot, which makes it easier to put the guide block for inserting the pen shell and pen refill into the mounting slot, and can also prevent the pen refill from contacting the side wall of the mounting slot during movement, which would cause the FPC to curl or be damaged, thus improving the yield rate of electronic pen assembly.

[0051] The following is combined Figures 1 to 11 The following describes embodiments of the present invention.
[0052] According to an embodiment of the present invention, an electronic pen assembly device 1 is provided, which includes a body 100, a guide block 200, a sliding module 300, a pressure detection element 400, and a pen refill pusher 500.
[0053] The guide block 200 is detachably mounted on the body 100, and the guide block 200 is provided with a guide hole 210. The guide hole 210 passes through the guide block 200, forming a pen shell insertion port 2111 at one end of the guide block 200, and a pen refill insertion port 2121 at the other end of the guide block 200.
[0054] The sliding module 300 includes a slide rail 310 and a slider 320. The slide rail 310 is disposed on the body 100, and the slider 320 is slidably disposed on the slide rail 310, and the slider 320 slides axially along the guide hole 210. A pressure detection element 400 is disposed on the side of the slider 320 facing the guide block 200. A pen refill pusher 500 is disposed on the side of the pressure detection element 400 facing the guide block 200.
[0055] Specifically, during the assembly of the electronic pen, the guide block 200 is first removed from the body 100. The pen shell 2 of the electronic pen to be assembled is inserted into the guide hole 210 through the pen shell insertion port 2111, and the pen refill 3 of the electronic pen to be assembled is inserted into the guide hole 210 through the pen refill insertion port 2121, thus achieving pre-positioning between the pen shell 2 and the pen refill 3. Both the pen shell 2 and the pen refill 3 can be constructed as cylindrical, and the guide hole 210 is constructed as a cylindrical hole. Then, the guide block 200 is installed onto the body 100. On the 0, the control slider 320 moves along the slide rail 310 towards the guide block 200. The slider 320 drives the pressure detection element 400 and the pen refill pusher 500 to move towards the guide block 200 simultaneously. Finally, the pen refill pusher 500 contacts the pen refill 3 and pushes the pen refill 3 towards the pen shell 2 until the pen refill 3 is inserted into the pen shell 2. After the pen refill 3 is inserted into the pen shell 2, the slider 320 stops moving. The pressure detection element 400 detects the pressure of the pen refill pusher 500 in real time.
[0056] By setting up a pressure detection component 400, the pressure of the pen refill component 500, i.e., the pressure on the pen refill 3, can be monitored in real time, preventing abnormal pushing force from damaging the pen refill 3 or the pen shell 2, thereby improving product yield. Furthermore, since the guide block 200 is detachable from the body 100, it is convenient to insert the pen shell 2 and the pen refill 3 into the guide hole 210, improving the assembly efficiency of the electronic pen.
[0057] The pen shell 2 and pen refill 3 are pre-positioned by the guide block 200, and the pen refill pusher 500 pushes the pen refill 3 into the pen shell 2. There is no need for manual control of the relative position of the pen shell 2 and pen refill 3. During the assembly process, the pen shell 2 and pen refill 3 are almost only subjected to the axial thrust applied by the pen refill pusher 500 along the guide hole 210, and are almost not subjected to deflection force. This can improve the installation accuracy and consistency between the pen shell 2 and pen refill 3. Not only is the production efficiency high, but the FPC is also less likely to interfere with the pen shell 2, reducing the probability of FPC curling and damage, and improving the yield of electronic pens.
[0058] like Figure 1 and Figure 5 As shown, in some embodiments, the push pen refill 500 has a guide groove 510 on the side facing the guide block 200, and the cross-sectional area of the guide groove 510 gradually increases towards the guide block 200. That is, the area of the opening of the guide groove 510 is larger than the area of the bottom of the guide groove 510.
[0059] In this way, when the pen refill pusher 500 moves toward the guide block 200, the pen refill 3 can be easily inserted into the guide groove 510. As the pen refill 3 is inserted into the bottom of the guide groove 510, the positioning between the pen refill pusher 500 and the pen refill 3 can be achieved, so that the central axis of the guide groove 510 of the pen refill pusher 500 and the central axis of the pen refill 3 coincide or approximately coincide, and the cooperation effect between the pen refill pusher 500 and the pen refill 3 is good.
[0060] like Figures 2-5 As shown, in some embodiments, the electronic pen assembly device 1 further includes a limiting block 800, which is disposed on the body 100 and located between the slider 320 and the guide block 200. The slider 320 can abut against the limiting block 800 within its sliding stroke.
[0061] Specifically, when the slider 320 moves toward the guide block 200, the slider 320 will gradually approach the limit block 800 until the slider 320 abuts against the limit block 800, thereby limiting the maximum depth of the pen refill 3 inserted into the pen shell 2, preventing the pen refill 3 from being over-inserted into the pen shell 2, which can reduce the probability of damage to the pen refill 3 and the pen shell 2, and improve the installation accuracy and consistency.
[0062] like Figures 7-10 As shown, in some embodiments, the guide hole 210 includes a pen shell insertion segment 211 and a pen refill insertion segment 212. The pen shell insertion segment 211 communicates with the pen shell socket 2111, and the pen refill insertion segment 212 communicates between the pen shell insertion segment 211 and the pen refill socket 2121. The central axis of the pen refill insertion segment 212 and the central axis of the pen shell insertion segment 211 can be set to coincide. On a plane perpendicular to the axis of the guide hole 210, the projection of the pen refill insertion segment 212 is located within the projection of the pen shell insertion segment 211.
[0063] In other words, the cross-sectional area of the pen shell insertion segment 211 is larger than that of the pen refill insertion segment 212, forming a step between the pen refill insertion segment 212 and the pen shell insertion segment 211. When the pen shell 2 is inserted into the pen shell insertion segment 211 from the pen shell insertion port 2111, the pen shell 2 will abut against the step between the pen refill insertion segment 212 and the pen shell insertion segment 211, thereby determining the relative position between the pen shell 2 and the guide block 200. The pen refill 3 is inserted into the pen refill insertion segment 212 from the pen refill insertion port 2121. Since the cross-sectional area of the pen refill 3 is smaller, the pen refill 3 can pass through the pen refill insertion segment 212 and be inserted into the pen shell 2. The assembled pen refill 3 and pen shell 2 can be pulled out from the pen shell insertion segment 211.
[0064] Furthermore, the cross-sectional area of the pen refill segment 212 gradually increases in the direction away from the pen housing segment 211. This facilitates the insertion of the pen refill 3 into the pen refill segment 212 and reduces friction between the pen refill 3 and the inner wall of the pen refill segment 212, thereby reducing the probability of FPC curling and damage and improving the yield rate of the electronic pen.
[0065] Furthermore, the inner circumferential surface of the pen shell insertion segment 211 is provided with a positioning protrusion 2112. For example, the outer contour of the cross-section of the portion of the pen shell 2 inserted into the pen shell insertion segment 211 can be hexagonal, and the inner contour of the cross-section of the pen shell insertion segment 211 is also hexagonal, to adapt to the shape of the pen shell 2. Specifically, the outer circumferential surface of the pen shell 2 is provided with a notch 21, and the positioning protrusion 2112 of the pen shell insertion segment 211 cooperates with the notch 21 of the pen shell 2 to achieve the positioning of the pen shell 2 and the guide block 200 in the circumferential direction of the guide hole 210, and to prevent the guide block 200 and the pen shell 2 from rotating relative to each other.
[0066] At least a portion of the inner circumferential surface of the pen refill section 212 is constructed as a positioning plane 2122. Specifically, the outer circumferential surface of the pen refill 3 also includes a plane that mates with the positioning plane 2122. This enables the guide block 200 and the pen refill 3 to be positioned in the circumferential direction of the guide hole 210, and prevents relative rotation between the guide block 200 and the pen refill 3. This, in turn, determines the relative position of the pen shell 2 and the pen refill 3 in the circumferential direction of the guide hole 210, thereby improving the installation accuracy.
[0067] like Figures 1-6 As shown, in some embodiments, the electronic pen assembly device 1 further includes a push plate 630, a slide bar 640, and an elastic element 650.
[0068] A push plate 630 is slidably mounted on the body 100, a slide rod 640 is connected to the push plate 630, and a slider 320 is slidably connected to the slide rod 640. An elastic element 650 is sleeved on the slide rod 640 and is located between the push plate 630 and the slider 320. The elastic element 650 can be a spring, and the push plate 630 can slide relative to the body 100 manually, pneumatically, or electrically to allow the slider 320 to move closer to or further away from the guide block 200, thus improving the structural flexibility of the electronic pen assembly device 1.
[0069] By setting an elastic element 650 sleeved on the slide bar 640, and the elastic element 650 being located between the push plate 630 and the slider 320, when the slider 320 abuts against the pen refill 3, and when the slider 320 pushes the pen refill 3 to move, the elastic element 650 can undergo elastic deformation to absorb part of the pressure between the slider 320 and the pen refill 3, thus preventing the pen refill 3 and the pen shell 2 from being damaged due to excessive force.
[0070] Furthermore, the electronic pen assembly device 1 also includes a driver 600. The driver 600 includes a driver body 610 and a driver rod 620. The driver body 610 is disposed on the body 100, and the driver rod 620 is telescopically connected to the driver body 610. The sliding module 300 and the slide rod 640 are disposed outside the body 100. The body 100 has a through hole 110, and the push plate 630 is slidably inserted through the through hole 110 and connected to the driver rod 620.
[0071] For example, the driver 600 can be a cylinder.
[0072] By setting the driver 600 to drive the push plate 630 to slide relative to the body 100, automatic assembly between the pen refill 3 and the pen shell 2 can be achieved without manually pushing the slider 320 to move, thus improving the degree of automation.
[0073] Since the driver 600 is located inside the body 100, its exposed area is reduced. This prevents dust and other impurities from affecting the operation of the driver 600 and also allows the air pipe connected to the driver 600 to be hidden inside the body 100, improving the neatness of the piping arrangement of the electronic pen assembly device 1 and facilitating its normal operation. Furthermore, by providing the through hole 110, the push plate 630 can be moved relative to the body 100 while simultaneously connecting to both the driver 600 and the sliding module 300.
[0074] like Figures 1-6 as well as Figure 11As shown, in some embodiments, the electronic pen assembly device 1 further includes a mounting base 710 and a positioning base 720. The mounting base 710 and the positioning base 720 are disposed on the body 100, and the mounting base 710 has a mounting groove 711, with a guide block 200 disposed within the mounting groove 711. The positioning base 720 has a pen housing positioning groove 721, with a pen housing through hole 7211 on the side of the pen housing positioning groove 721 facing the mounting base 710, and a pen housing stop portion 7212 on the side of the pen housing positioning groove 721 facing away from the mounting base 710.
[0075] The mounting slot 711 fixes the relative position between the mounting base 710 and the guide block 200, thereby fixing the relative position between the guide block 200 and the body 100. The pen shell positioning slot 721 fixes the relative position between the pen shell 2 and the positioning base 720. Since the pen shell 2 is placed into the pen shell positioning slot 721 after the pen shell 2 and the guide block 200 are fixed, the pen shell through hole 7211 can avoid interference between the side walls of the pen shell 2 and the pen shell positioning slot 721. Furthermore, the end of the pen shell 2 away from the guide block 200 abuts against the pen shell stop part 7212. When the pen refill pusher 500 pushes the pen refill 3 to move within the guide block 200, and when the pen refill 3 is inserted into the pen shell 2, the guide block 200 and the pen shell 2 will not move relative to the body 100, thereby improving the installation accuracy and efficiency of the pen shell 2 and the pen refill 3.
[0076] Furthermore, such as Figure 5 As shown, the lowest point of the guide hole 210 is higher than the side wall of the mounting groove 711.
[0077] This avoids interference between the pen shell 2 and pen refill 3 inserted into the guide hole 210 and the side wall of the mounting groove 711. This facilitates the placement of the guide block 200 containing the pen shell 2 and pen refill 3 into the mounting groove 711, and also prevents the pen refill 3 from contacting the side wall of the mounting groove 711 during movement, which could cause the FPC to curl or be damaged, thus improving the yield rate of electronic pen assembly.
[0078] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
