Description

Technical Field

[0001] This invention relates to the technical field of electronic pens, and more particularly to a multi-angle pinch calibration test module for electronic pens. Background Technology

[0002] An electronic pen, also known as an electronic stylus, is a human-computer interaction input tool used in conjunction with touch-screen electronic devices based on technologies such as electromagnetic induction, capacitive induction, and pressure sensing. During the manufacturing process, electronic pens are prone to problems such as inconsistent sensitivity when lightly pinched at different angles and deviations in the pressing threshold due to limitations in the processing precision of components, the stability of assembly processes, and differences in material properties. Therefore, calibration testing equipment is needed to test and calibrate electronic pens before they leave the factory.

[0003] Currently, traditional calibration testing modules use stress sensors for calibration when testing electronic pens. Stress sensors can usually only detect forces in a specific direction or at a single angle, making it difficult to fully cover the multi-angle light pinching situations that electronic pens may encounter in actual use. Moreover, the stress sensor calibration of styluses on the market currently uses motors and pressure sensors for pressure testing. The motor speed is slow and the downward pressure cannot be controlled, resulting in unstable pressure and an accuracy of only ±50g. As a result, it is difficult for the test results to fully reflect the performance of electronic pens in real-world usage scenarios. Summary of the Invention

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The following describes an embodiment of the present invention, an electronic pen multi-angle pinch calibration test module, with reference to the accompanying drawings.

[0021] like Figures 1-7 As shown, an embodiment of the present invention provides an electronic pen multi-angle pinch calibration test module, comprising: a test machine 1 and a test mechanism 5, wherein the test mechanism 5 is disposed inside the test machine 1.

[0022] The testing mechanism 5 includes a fixed plate 51, a first power source 52, a first slide rail 53, a tray 54, a driving component 55, a guide block 56, a protective surface 57, a fixed block 58, and an electronic pen 59.

[0023] The fixed plate 51 is installed inside the test machine 1, the first power source 52 is installed on the fixed plate 51, the first slide rail 53 is installed on the fixed plate 51, the tray 54 is installed on the moving block of the first slide rail 53, the drive component 55 is installed on the tray 54, the guide block 56 is connected to the output end of the drive component 55, the anti-corrosion surface 57 is installed on the outer wall of the guide block 56, the fixed block 58 is fixed on the tray 54, and the electronic pen 59 is detachably placed on the fixed block 58 and the guide block 56.

[0024] It should be noted that the first power source 52 described in this embodiment of the invention is a telescopic cylinder. The first power source 52 can drive the tray 54 to perform linear reciprocating motion on the first slide rail 53, thereby moving the electronic pen 59 placed on the tray 54 to different test positions. The driving component 55 is a 200W servo motor. The driving component 55 can precisely control the rotation of the guide block 56, so that the electronic pen 59 can simulate multiple usage angles during the test. The shape of the protective surface 57 matches the shape of the electronic pen 59, and can protect the electronic pen 59 during the test to prevent it from being damaged by force.

[0025] Specifically, when the electronic pen 59 needs to be calibrated by pinching at multiple angles, the first power source 52 is started first. The first power source 52 drives the tray 54 to move along the first slide rail 53 to the preset test position. At this time, the electronic pen 59 is accurately placed between the fixed block 58 and the guide block 56. The guide block 56 is rotated by the drive component 55, so that the electronic pen 59 is adjusted to the angle to be tested.

[0026] In one embodiment of this application, such as Figure 1 As shown, the test machine 1 is equipped with signal lights 2, and the outer wall of the test machine 1 is equipped with a display screen 3.

[0027] Understandably, indicator light 2 can intuitively display the working status of the test module. For example, when the test starts, ends, or an abnormality occurs, indicator light 2 will use different colored lights to indicate the status, making it easy for operators to quickly understand the module's operation. Display screen 3 is used to display various data during the test in real time, such as the pressure value of the electronic pen 59 when pinched at different angles, test time, number of tests, etc. Operators can monitor and analyze the test process based on the data displayed on display screen 3.

[0028] In one embodiment of this application, such as Figure 1 As shown, a storage cabinet 4 is provided on the outer wall of the testing machine 1.

[0029] Understandably, storage cabinet 4 is a pull-out cabinet containing a computer and a mouse. The design of storage cabinet 4 facilitates the storage and processing of test data by operators. The computer can be used to record and analyze various data generated during the test, while the mouse allows operators to easily operate the computer.

[0030] In one embodiment of this application, such as Figure 3 As shown, a pressing component 6 is provided on the fixing plate 51.

[0031] The pressing component 6 includes a support frame 61, a mounting plate 62, a first connecting plate 63, a second slide rail 64, a second power source 65, a locking block 66, a connecting block 67, a first support roller 68, a housing 69, and a weight 610.

[0032] The support frame 61 is fixed on the fixed plate 51, the mounting plate 62 is installed on the support frame 61, the first connecting plate 63 is fixed on the outer wall of the support frame 61, the second slide rail 64 is installed on the outer wall of the first connecting plate 63, the second power source 65 is installed on the outer wall of the first connecting plate 63, and the output end of the second power source 65 is connected to the moving block of the second slide rail 64, the locking block 66 is installed on the moving block of the second slide rail 64, one end of the connecting block 67 is installed inside the locking block 66, the first support roller 68 is rotatably connected to the other end of the connecting block 67, the outer shell 69 is installed on the locking block 66, and the weight 610 is installed inside the outer shell 69.

[0033] It should be noted that the second power source 65 described in this embodiment of the invention is a telescopic cylinder. The second power source 65 drives the moving block of the second slide rail 64 to move vertically, thereby driving the locking block 66, the connecting block 67 and the first support roller 68 to achieve lifting and lowering actions. The weight 610 is placed inside the outer shell 69. The downward pressure can be adjusted by increasing or decreasing the number of weights 610 to meet the calibration and testing requirements of electronic pens 59 of different specifications. The first support roller 68 is made of PPS and contacts the body of the electronic pen 59, ensuring the accuracy of downward pressure while avoiding damage to the pen body.

[0034] Specifically, the second power source 65 drives the moving block of the second slide rail 64 to move downward, and the locking block 66 descends accordingly, causing the connecting block 67 and the first support roller 68 to move downward synchronously. The weight 610 inside the outer shell 69 is adjusted and applies precise pressure to the electronic pen 59 through the first support roller 68, realizing multi-pressure, multi-position, and multi-angle calibration tests.

[0035] In one embodiment of this application, such as Figure 1 As shown, a maintenance window 8 is provided on the outer wall of the testing machine 1, and a safety light curtain 9 is installed on the outer wall of the testing machine 1.

[0036] Understandably, maintenance window 8 provides operators with a convenient access for inspection and repair. When the test module malfunctions or requires routine maintenance, operators can open maintenance window 8 to inspect, replace, or adjust the internal components of the test machine 1 without disassembling the entire test module, greatly improving maintenance efficiency. If an operator accidentally inserts their hand or other object into the test area during testing, the safety light curtain 9 will immediately detect the obstruction and quickly send a signal to the control system. Upon receiving the signal, the control system will immediately stop the test module's operation, effectively preventing injury to the operator and ensuring their personal safety.

[0037] In one embodiment of this application, such as Figure 1As shown, a test light 10 is installed on the outer wall of the tray 54, and an operation button 11 is installed on the outer wall of the test machine 1.

[0038] Understandably, the test light 10 provides intuitive visual feedback during testing. When the electronic pen 59 is in normal testing mode, the test light 10 displays green; when an abnormality occurs, such as pressure exceeding the set range or the electronic pen 59 shifting position, the test light 10 turns red to remind the operator to handle the situation promptly. The operation button 11 allows the operator to manually control the test module, such as starting or resetting the test, or stopping the test in an emergency to prevent unexpected situations during testing.

[0039] In one embodiment of this application, such as Figure 2 As shown, a support assembly 7 is provided on the bottom wall of the fixing plate 51.

[0040] The support assembly 7 includes a support plate 71, a third slide rail 72, a second connecting plate 73, a fourth slide rail 74, a third power source 75, a mounting component 76, a first adjusting block 77, a second adjusting block 78, and a second support roller 79.

[0041] Support plate 71 is installed on the bottom wall of fixed plate 51, third slide rail 72 is installed on the outer wall of support plate 71, second connecting plate 73 is installed on the moving block of third slide rail 72, fourth slide rail 74 is installed on the outer wall of second connecting plate 73, third power source 75 is installed on the moving block of fourth slide rail 74, mounting piece 76 is connected to the output end of third power source 75, first adjusting block 77 is installed on mounting piece 76, second adjusting block 78 is installed on first adjusting block 77, and second support roller 79 is rotatably installed on the outer wall of second adjusting block 78.

[0042] It should be noted that the third power source 75 described in the embodiments of the present invention is a telescopic cylinder. The third power source 75 can drive the mounting component 76 to perform linear reciprocating motion on the fourth slide rail 74, thereby driving the first adjusting block 77, the second adjusting block 78 and the second support roller 79 to adjust their positions.

[0043] Specifically, when the support position needs to be adjusted according to different sizes of the electronic pen 59 or testing requirements, the third power source 75 is activated, driving the moving block of the fourth slide rail 74 to move, thereby moving the mounting component 76, the first adjusting block 77, the second adjusting block 78, and the second support roller 79 to the appropriate position. By adjusting the first adjusting block 77 and the second adjusting block 78, the height and angle of the second support roller 79 can be further fine-tuned to ensure that the second support roller 79 can accurately and stably support the electronic pen 59, providing reliable support conditions for calibration testing and ensuring the accuracy and reliability of the test results.

[0044] In one embodiment of this application, such as Figure 6 As shown, an electrical control box 12 is installed at the bottom of the test machine 1, and a cooling fan 13 is installed on the outer wall of the electrical control box 12.

[0045] Understandably, the electrical control box 12, as the core control unit of the test module, integrates various electrical components and circuit boards to precisely control and adjust various parameters during the test process. The cooling fan 13 can dissipate the heat generated inside the electrical control box 12 in a timely manner, preventing the performance of electrical components from deteriorating or being damaged due to excessive temperature, thereby ensuring that the test module can operate stably for a long time.

[0046] In one embodiment of this application, such as Figure 1 and Figure 6 As shown, the bottom wall of the electrical control box 12 is equipped with shock-absorbing pads 14 and casters 15.

[0047] Understandably, the shock-absorbing pad 14 is made of highly elastic material, which can effectively absorb and buffer the vibration generated by the test module during operation, avoid the vibration from causing adverse effects on the electrical components inside the control box 12, and further ensure the stability and reliability of the test module. The casters 15 make the entire test module have good mobility, and the operator can move the test module to different working positions according to actual needs, which improves the flexibility and ease of use of the equipment.

[0048] In one embodiment of this application, such as Figure 1 and Figure 4 As shown, the bottom wall of the electrical control box 12 is equipped with a foot 16, and the bottom wall of the foot 16 is equipped with an anti-slip pad 17.

[0049] Understandably, the stand 16 provides a stable support base for the test module. When the test module needs to be fixed in a certain position for long-term testing, the stand 16 can ensure that the module will not move or tilt due to external forces, thus ensuring the stability and accuracy of the testing process. The anti-slip pad 17 further enhances the anti-slip performance of the stand 16, effectively preventing the stand 16 from sliding.

[0050] Working Principle: When this multi-angle pinch calibration test module for electronic pens is in operation, the electronic pen 59 is first detachably placed on the fixing block 58 and guide block 56 according to the test requirements. The first power source 52 is activated, driving the tray 54 to move along the first slide rail 53 to the preset test position, placing the electronic pen 59 at the appropriate test point. Next, the drive component 55 (200W servo motor) precisely controls the rotation of the guide block 56, driving the electronic pen 59 to adjust to the required test angle. At the same time, if it is necessary to adjust the downward pressure, it can be achieved by increasing or decreasing the number of weights 610 placed inside the outer casing 69. The second power source 65 drives the moving block of the second slide rail 64 to move up and down linearly, driving the locking block 66, connecting block 67 and the first support roller 68 to achieve lifting and lowering actions. The first support roller 68 contacts the body of the electronic pen 59 and applies precise pressure to it, completing the calibration test for multiple pressures, multiple positions, and multiple angles. During testing, indicator light 2 visually displays the working status of the test module, while display screen 3 displays various data in real time, such as the pressure value of the electronic pen 59 when lightly pinched at different angles, test time, and number of tests, facilitating monitoring and analysis by operators. Test light 10 provides visual feedback during testing, displaying green when the test is normal and turning red when an abnormality occurs. When the support position needs to be adjusted according to the different sizes of the electronic pen 59 or testing requirements, the third power source 75 is activated, driving the moving block of the fourth slide rail 74 to move, which in turn moves the mounting part 76, the first adjusting block 77, the second adjusting block 78, and the second support roller 79 to the appropriate position. Then, by adjusting the first adjusting block 77 and the second adjusting block 78, the height and angle of the second support roller 79 are finely adjusted to ensure that it accurately and stably supports the electronic pen 59. The electrical control box 12 serves as the core control unit, precisely controlling and adjusting various parameters during the testing process. The cooling fan 13 dissipates the heat generated inside in a timely manner, the shock-absorbing pad 14 absorbs and buffers the vibrations generated during operation, the casters 15 facilitate the movement of the test module, and the feet 16 and anti-slip pads 17 provide stable support for the test module, preventing it from moving or tilting due to external forces, thus ensuring the stability and accuracy of the testing process.
