[0032] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.
[0033] Reference Figures 1 to 3This application provides an electronic pen testing device, comprising a frame 10, a first driving mechanism 20, a first clamping member 30, a second clamping member 40, a second driving mechanism 50, and a counterweight 60. The first driving mechanism 20 is connected to the frame 10. The first clamping member 30 and the second clamping member 40 are spaced apart along a first direction Y. The first driving mechanism 20 can drive the first clamping member 30 and the second clamping member 40 to move closer or further apart along the first direction Y. The first clamping member 30 is provided with a first touch portion 301, and the second clamping member 40 is provided with a second touch portion 401. An electronic pen holding space is formed between the first touch unit 301 and the second touch unit 401. The first touch unit 301 and the second touch unit 401 are used to touch the touch area on the body of the electronic pen 110 for touch detection. The second drive mechanism 50 is connected to the frame 10. The counterweight 60 is disposed on one side of the electronic pen holding space along the second direction Z. The second drive mechanism 50 can drive the counterweight 60 to move closer to or away from the electronic pen holding space along the second direction Z. The counterweight 60 is used to apply pressure to the tip 111 of the electronic pen 110 for pressure detection. The first direction Y intersects the second direction Z. Preferably, the first direction Y and the second direction Z are perpendicular to each other.
[0034] In this embodiment, the pen body of the electronic pen 110 is first clamped by the first touch part 301 of the first clamping member 30 and the second touch part 401 of the second clamping member 40. This not only fixes the electronic pen 110, but also detects the touch area on the pen body. In addition, this embodiment also uses the counterweight 60 to press the tip 111 of the fixed electronic pen 110 to perform pressure sensitivity testing on the electronic pen 110. The two testing structures are integrated, so that two test results can be obtained at the same time, which has high detection efficiency and reduces costs.
[0035] It should be noted that before testing the electronic pen 110, it can be connected to a display device such as a smart tablet to make the touch test results and pressure sensitivity test results more intuitive.
[0036] Specifically, the first touch unit 301 and the second touch unit 401 are clamped on the touch area of the electronic pen 110 to simulate the touch area of the electronic pen 110 by a human hand for touch detection. The detection result can be obtained from the touch area of the electronic pen 110 or from the corresponding feedback presented on the display device, thereby determining whether the function of the touch area of the electronic pen 110 is normal and achieving the purpose of detecting the touch area of the electronic pen 110.
[0037] In addition, the counterweight 60 is an object with a certain weight. After it presses against the tip 111, it can be converted into pressure data. This pressure data can be compared with the pressure data detected by the electronic pen 110 itself, so as to determine whether the pressure detection function of the electronic pen 110 is normal, so as to achieve the purpose of pressure sensitivity testing of the electronic pen 110. Of course, the above pressure data can be displayed intuitively on the display device.
[0038] In some embodiments, refer to Figure 1 and Figure 4 The electronic pen testing device also includes a third drive mechanism 70 and a positioning seat 80. The third drive mechanism 70 is connected to the frame 10, and the positioning seat 80 can be limited and connected to the pen tail end 112 of the electronic pen 110. The third drive mechanism 70 can drive the positioning seat 80 to move closer to or away from the electronic pen clamping space along a third direction X; wherein, the first direction Y, the second direction Z, and the third direction X intersect each other. Preferably, the first direction Y, the second direction Z, and the third direction X are perpendicular to each other.
[0039] In this embodiment, the positioning seat 80 fixes the electronic pen 110 and can approach and be placed within the electronic pen clamping space under the drive of the third driving mechanism 70, which can also be understood as the loading process; then the first driving mechanism 20 drives the first clamping member 30 and the second clamping member 40 to approach and clamp the electronic pen 110, while the counterweight 60 can press down on the tip 111 of the electronic pen 110. After the test is completed, the unloading process is the reverse of the loading process described above, and will not be described again here.
[0040] Understandably, the first clamping member 30 and the second clamping member 40 can prevent the electronic pen 110 from being pressed and moving along the second direction Z by friction. Furthermore, the positioning seat 80 abuts against the pen tail end 112 of the electronic pen 110, which can also prevent the electronic pen 110 from moving along the second direction Z.
[0041] In addition, the positioning base 80 is provided with an extension 801, which is distributed along the second direction Z and at least covers part of the circumference of the body of the electronic pen 110, resulting in better positioning effect.
[0042] Optionally, the first drive mechanism 20, the second drive mechanism 50, and the third drive mechanism 70 may include a pneumatic cylinder, a hydraulic cylinder, a linear motor, or a rotary motor in conjunction with a lead screw assembly.
[0043] In some embodiments, refer to Figure 1 and Figure 4 The frame 10 is provided with slide rails 90 distributed along the third direction X, and the positioning seat 80 is slidably connected to the slide rails 90.
[0044] In this embodiment, the positioning seat 80 can slide directly or indirectly on the slide rail 90 through a slider, thereby limiting the movement trajectory of the positioning seat 80, ensuring that the positioning seat 80 can be accurately positioned within the electronic pen clamping space, and making the movement process of the positioning seat more stable.
[0045] In some embodiments, refer to Figure 3 and Figure 5 The counterweight 60 includes a counterweight block 601, a rod 602, and a pressing member 603. One end of the rod 602 is connected to the counterweight block 601, and the other end of the rod 602 is connected to the pressing member 603. The pressing member 603 can press against the tip 111 of the electronic pen 110. The power output part of the second drive mechanism 50 is provided with a limiting plate 120, and the rod 602 passes through the limiting plate 120 along the second direction Z.
[0046] It should be noted that the specific structure of the counterweight 60 can take many forms. For example, referring to this embodiment, the counterweight 60 uses the gravity of the counterweight block 601 to convert into the pressure required for pressure sensitivity testing, and uses the pressure-pressing member 603 to directly or indirectly press against the tip 111 of the electronic pen 110. At the same time, a limiting plate 120 is set to limit the rod 602 of the counterweight 60 to prevent the rod 602 from tilting, ensuring that the pressure is always directly facing the tip 111 of the electronic pen 110 along the second direction Z, resulting in better testing effect.
[0047] In some embodiments, refer to Figure 3 The counterweight 60 also includes a pressure sensor 604, which is located on the side of the pressing member 603 facing the electronic pen clamping space. The pressing member 603 can press the tip 111 of the electronic pen 110 through the pressure sensor 604.
[0048] In this embodiment, the pressure sensor 604 can directly and accurately obtain the pressure applied to the tip 111 of the electronic pen 110, making the test results more accurate.
[0049] In some embodiments, refer to Figure 5 and Figure 6 The counterweight 60 also includes a limiting sleeve 605, which is sleeved on the rod 602 and has a limiting part 6051. The limiting plate 120 has a limiting groove 121 on the side away from the electronic pen clamping space, which can accommodate and abut the limiting part 6051. The second drive mechanism 50 can drive the counterweight 60 away from the electronic pen clamping space through the cooperation of the limiting groove 121 and the limiting part 6051.
[0050] Specifically, refer to Figure 6The limiting plate 120 is provided with a clearance hole 122, which is coaxial with the limiting groove 121. The limiting sleeve 605 passes through the clearance hole 122, and the limiting part 6051 of the limiting sleeve 605 is located in the limiting groove 121. More specifically, the second driving mechanism 50 can drive the limiting plate 120 away from the electronic pen 110, thereby raising the limiting sleeve 605 and driving the rod 602 and the counterweight 601 to move upward, so that the pressing member 603 can separate from the tip 111 of the electronic pen 110 or reduce the pressure on the tip 111.
[0051] It should be noted that if the limiting sleeve 605 is not set, it is also a viable implementation method for the limiting plate 120 to directly abut against and lift the counterweight 601.
[0052] Understandably, the second drive mechanism 50 drives the limiting plate 120 closer to the electronic pen 110, thereby preventing the limiting plate 120 from applying a supporting force to the limiting sleeve 605. In other words, the entire weight of the counterweight 601 is converted into a resisting force applied to the tip 111 of the electronic pen 110, completing the test. Furthermore, in some tests, if it is not desired that the entire weight of the counterweight 601 be applied to the electronic pen 110, the distance between the limiting plate 120 and the tip 111 of the electronic pen 110 can be controlled. This allows the limiting plate 120 to apply a partial supporting force to the limiting sleeve 605, converting part of the weight of the counterweight 601 into a resisting force. Due to the presence of the pressure sensor 604, the magnitude of this resisting force is always obtainable, demonstrating a clever structural design.
[0053] In some embodiments, the mass of the counterweight 601 is m, and satisfies 510g≤m≤550g.
[0054] In this embodiment, if the mass of the counterweight 601 is too large, it will cause excessive load on the electronic pen 110 or the limiting plate 120, and may even damage the tip 111; if the mass of the counterweight 601 is too small, it will be difficult to meet the testing requirements. Therefore, the mass of the counterweight 601 should be moderate, that is, the value of m should be moderate. For example, m can be any one of 510g, 515g, 520g, 525g, 530g, 535g, 540g, 545g and 550g or within the range of any two of these values.
[0055] In some embodiments, the first touch portion 301 and / or the second touch portion 401 are soft structures.
[0056] In this embodiment, the first touch unit 301 and / or the second touch unit 401 are soft structures, which can not only avoid pinching the electronic pen 110, but also simulate the touch of a finger, making the test results more accurate.
[0057] In some embodiments, both the first touch portion 301 and the second touch portion 401 are conductors, as shown in the reference. Figure 2 The dimension of the first touch unit 301 along the second direction Z is greater than the dimension of the second touch unit 401 along the second direction Z.
[0058] It should be noted that, typically, the touch area of the electronic pen 110 involves capacitive touch technology. The first touch part 301 and the second touch part 401 need to be conductive materials (such as conductive silicone) to change the electric field of the touch area of the electronic pen 110, thereby detecting a touch.
[0059] Understandably, if the touch area of the electronic pen 110 involves resistive touch technology or other touch technologies, it is also desirable to implement the first touch portion 301 and the second touch portion 401 as non-conductive materials.
[0060] Furthermore, both the first touch unit 301 and the second touch unit 401 are conductive, which can also conduct away static electricity on the electronic pen 110, avoiding affecting the test results. Specifically, the first touch unit 301 has a larger dimension along the second direction Z, covering more area of the electronic pen 110, and can conduct static electricity from more areas of the pen, resulting in better test performance; the second touch unit 401 has a smaller dimension along the second direction Z, which can meet the requirement of covering the touch area of the electronic pen 110, while also avoiding the positioning seat 80, resulting in high space utilization.
[0061] In some embodiments, refer to Figure 1 The electronic pen testing device also includes a photoelectric sensor 100, which includes a first device 101 and a second device 102. The first device 101 and the second device 102 are spaced apart along the first direction Y, and a photoelectric detection area is formed between them. The photoelectric detection area is located on one side of the positioning seat 80 along the third direction X, and the movement path of the positioning seat 80 does not exceed the photoelectric detection area.
[0062] It should be noted that the photoelectric sensor 100 can also be referred to as a safety light curtain, safety light grid, or photoelectric protection device, and is an important safety device used in industrial environments. For example, the first device 101 can create a detection area, i.e., a photoelectric detection area, by emitting a light beam (e.g., infrared light) and receiving these light beams on the opposite second device 102; or the first device 101 can emit and receive light beams, and the second device 102 can reflect the light beam emitted by the first device 101 back to the first device 101, so as to form a photoelectric detection area between the first device 101 and the second device 102; when any object (usually part of a human body) enters the photoelectric detection area, the photoelectric sensor 100 can quickly detect it and send a signal to stop the operation of the relevant machine to avoid accidental injury.
[0063] In this embodiment, the positioning seat 80 moves along a third direction X between the electronic pen holding space and the photoelectric detection area, and it can move into the electronic pen holding space, but cannot move into the photoelectric detection area.
[0064] It should be noted that the electronic pen testing device also includes other components, such as a digital display timer that communicates with the control unit, a manual start button, etc. Other components will not be described here.
[0065] In particular, the term "and / or" in this application should be understood as follows:
[0066] In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.
[0067] In the second case, the term "and / or" between the last two of three or more subjects means including at least any one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject;
[0068] Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.
[0069] Finally, although the embodiments of this application have been described above in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the concept of this application, and such modifications and variations all fall within the scope of protection of this application.
