[0067] In this specification, many specific details are provided to provide a thorough understanding of the specific embodiments of the present invention; however, those skilled in the art should know that the present invention can still be practiced without one or more of these specific details; in other cases, well-known details are not shown or described to avoid obscuring the main technical features of the present invention. The technical content and detailed description of the present invention are described as follows with the accompanying drawings:

[0068] See also Figure 1 and Figure 2 ,in Figure 1 It is a structural schematic diagram of the rocker device.

[0069] Figure 2 A block diagram of a testing device according to the present invention is provided.

[0070] The present invention discloses a test device for converting linear motion into circular motion (hereinafter referred to as the test device 2 in the specification). The test device 2 can control the internal components to perform linear motion without human intervention, guide the rocker device 1 to perform circular motion through the linear motion, thereby realizing the conversion of linear motion into circular motion, and detect the movement status of the rocker device 1 to determine whether the rocker device 1 is a good product or a defective product.

[0071] like Figure 1 As shown, the rocker device 1 referred to in the present invention is a device with a certain movable space, which can be tilted to the bottom in a 360-degree circular range towards the force direction after being subjected to force, and return to the initial position after the force is released.

[0072] Generally speaking, the rocker device 1 has at least a base 11, an extension rod 12 and a disc 13. The base 11 is placed on a plane. One end of the extension rod 12 is pivoted to the base 11, and the disc 13 is arranged on the other end. When the disc 13 or the extension rod 12 is subjected to force, it can tilt in the direction of the force based on the pivot point of the extension rod 12 on the base 11. When the force is released, the extension rod 12 returns to the initial position based on the pivot point (when in the initial position, the extension rod 12 is perpendicular to the base 11). Based on the characteristics of the pivot connection, the extension rod 12 can use the base 11 as a fixed point to rotate clockwise or counterclockwise, thereby realizing the rotation function of the rocker device 1.

[0073] The testing device 2 of the present invention is mainly used for Figure 1 The rocker device 1 shown performs linear conversion into circular motion, thereby realizing automatic circular testing of the rocker device 1 .

[0074] like Figure 2 As shown, the testing device 2 of the present invention comprises at least a control unit 21 and at least four push rods 23 , wherein the at least four push rods 23 are respectively electrically connected to the control unit 21 to be controlled by the control unit 21 and to be actuated.

[0075] In one embodiment, the control unit 21 may be, for example, a processor, a central processing unit (CPU), a micro control unit (MCU), a system on chip (SoC), a programmable logic controller (PLC), etc., but is not limited to this.

[0076] At least four push rods 23 can be implemented based on electromagnetic valves, electromagnets or pneumatic cylinders. Specifically, the control unit 21 can issue control commands to each push rod 23 to displace the push rod 23 by controlling the electromagnetic valves, electromagnets or pneumatic cylinders. When a push rod 23 receives a control command from the control unit 21 to perform a propulsion action, the push rod 23 moves linearly in a specified direction; when a push rod 23 receives a control command from the control unit 21 to perform a homing action, the push rod 23 moves linearly in the opposite direction of the specified direction to return to the original position.

[0077] The test device 2 of the present invention controls at least four push rods 23 to perform the pushing action and the returning action through the control unit 21, thereby utilizing the action of the push rods 23 to drive the rocker device 1 to perform circular motion. In this way, the linear motion of each push rod 23 can be converted into the circular motion of the rocker device 1, and then the motion status of the rocker device 1 can be detected.

[0078] Specifically, when using the test device 2 of the present invention to test the rocker device 1, the user needs to place the rocker device 1 in a position where all the push rods 23 can reach it. When a push rod 23 is controlled to perform a pushing action, the front end can touch the rocker device 1 (the extension rod 12 or the disc), and the push rod 23 continues to push, which can drive the rocker device 1 to fall to the bottom in the same direction. When this push rod 23 is controlled to perform a returning action, the force on the rocker device 1 is reduced, and it can return in the opposite direction of the force until the rocker device 1 returns to the initial position (that is, the extension rod 12 is perpendicular to the base 11).

[0079] The present invention utilizes at least two push rods 23 to perform a pushing action and a returning action respectively, and drives the rocker device 1 to rotate through a linear motion, thereby realizing a circular test.

[0080] Please also see Figure 3 , is a specific embodiment of the push rod arrangement diagram of the test device of the present invention. Figure 3 In the embodiment of the test device 2, the test device 2 has four push rods 23, including a first push rod 231, a second push rod 232, a third push rod 233 and a fourth push rod 234, wherein the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 are arranged at the same angle (i.e. Figure 3 The first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 are arranged in a circle, and an accommodating space 3 is formed at the center position of the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234.

[0081] In the present invention, the user can place the rocker device 1 to be tested in the accommodation space 3. At this time, the distances between the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 and the rocker device 1 are the same (all are distances L, and this distance L is a safe distance for the rocker device 1 to not touch the unactivated push rod on the side after being forced to fall to the bottom), so the rocker device 1 will not directly touch the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234. When one of the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 is controlled to move toward the accommodation space 3, its front end can touch the rocker device 1, and then drive the rocker device 1 to fall in the direction of the force.

[0082] Specifically, when testing, the control unit 21 first selects one of the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 as the current push rod (taking the first push rod 231 as an example), and controls the current push rod to move toward the center position, thereby causing the rocker device 1 to tip over.

[0083] After the rocker device 1 is tilted to the bottom, the control unit 21 selects the next push rod from the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 along the preset rotation direction (e.g., clockwise or counterclockwise). For example, if the rotation direction is clockwise, the control unit 21 selects the fourth push rod 234 as the next push rod; if the rotation direction is counterclockwise, the control unit 21 selects the second push rod 232 as the next push rod. Then, the control unit 21 controls the next push rod to advance toward the accommodating space 3, and controls the current push rod to return to its original position, wherein the advancing action of the next push rod and the returning action of the current push rod can be completed simultaneously or separately, but there is a time difference between the start time of the two (to be described in detail later).

[0084] Specifically, when the next push rod is pushed toward the accommodating space 3, it will also drive the rocker device 1 to fall to the bottom in the force direction after touching the rocker device 1 at the front end. In addition, when the next push rod performs a pushing action, the current push rod will also perform a returning action. When the pushing action of the next push rod and the returning action of the current push rod are completed, the rocker device 1 can complete a quarter of a circular motion. The control unit 21 controls the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 in sequence along the rotation direction to perform the above-mentioned actions (that is, control one push rod to perform a pushing action, and control another push rod to perform a returning action). When all the push rods in the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 complete a pushing action and a returning action, the rocker device 1 can complete a complete circular motion, and at this time the test equipment 2 can complete the circular test of the rocker device 1.

[0085] In one embodiment, the electronic device 5 is connected to the rocker device 1 and continuously detects the position signal of the rocker device 1. When the control unit 21 of the test device 2 controls the next push rod to perform the pushing action, it can continuously receive the position signal of the rocker device 1 from the electronic device 5, and compare the position signal with the previous position signal to determine whether the rocker device 1 starts to move. When it is determined that the position signal is different from the previous position signal, it means that the next push rod has touched the rocker device 1. At this time, the control unit 21 controls the current push rod to start the homing action. In other words, there is a time difference between the starting time point of the pushing action of the next push rod and the homing action of the current push rod, and the completion time point can be the same or different based on the speed adopted.

[0086] Please also see Figure 4 , which is a specific embodiment of the test flow chart of the present invention. The present invention further proposes a test method for converting linear motion into circular motion (hereinafter referred to as the test method in the specification), which is applied to Figure 2 and Figure 3 The test device 2 shown converts the linear motion of the internal first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 into the circular motion of the rocker device 1 placed in the accommodating space 3 of the test device 2, thereby testing whether the electronic signal of the rocker device 1 is correct.

[0087] Before testing the rocker device 1, the user needs to place the rocker device 1 to be tested in the accommodation space 3 and then start the testing device 2. Figure 4 As shown, after the test device 2 is started, the control unit 21 first selects one of the at least four push rods 23 as the current push rod, and controls the current push rod to advance toward the accommodating space 3 to apply force to the rocker device 1, thereby driving the rocker device 1 to fall to the bottom in the force direction (step S41).

[0088] After the rocker device 1 tilts to the bottom in the direction of the force, the control unit 21 selects one of at least four push rods 23 as the next push rod along the preset rotation direction, controls the next push rod to advance in the direction of the accommodating space 3 to apply force to the rocker device 1, and controls the current push rod to return to its original position (step S42).

[0089] Specifically, the top ends of all push rods 23 of the test device 2 are spaced the same distance from the rocker device 1 (eg Figure 3 The distance L shown in FIG. 1 is a distance L shown in FIG. 1 , and all push rods 23 may have the same or similar moving speed. More specifically, the speed of each push rod 23 when performing the pushing action may be equal to the speed when performing the returning action, thereby realizing a control mode of one slow advance plus one slow retreat. In one embodiment, the control unit 21 determines that the pushing action of the push rod is completed when the rocker device 1 tilts to the bottom in one direction, and determines that the returning action of the push rod is completed when the push rod returns to the initial position.

[0090] In one embodiment, the control unit 21 first controls the next push rod to move toward the accommodating space in step S42, and continuously obtains the position signal of the joystick device 1 through the electronic device 5, and then compares the position signal with the previous position signal. When it is determined that the position signal is the same as the previous position signal, it means that the joystick device 1 has not moved, that is, the next push rod has not yet touched the joystick device 1. At this time, the control unit 21 does not control the current push rod to return to its original position.

[0091] When it is determined that the position signal is different from the previous position signal, it means that the joystick device 1 is moving, that is, the next push rod has touched the joystick device 1. At this time, the control unit 21 controls the current push rod to start the return action. In one embodiment, the push action of the next push rod and the return action of the current push rod are completed at the same time.

[0092] After step S42, the control unit 21 continues to determine whether the propulsion action of the next push rod and the return action of the current push rod are completed (step S43), and before completion, continues to control the next push rod to perform the propulsion action based on the specified moving speed and at the same time controls the current push rod to perform the return action based on the same or similar moving speed.

[0093] After the pushing action of the next push rod and the returning action of the current push rod are completed, the control unit 21 determines whether all the push rods 23 have been controlled to perform one pushing action and one returning action respectively (step S44 ).

[0094] If the judgment in step S44 is no, the control unit 21 returns to step S42, takes the next push rod as the new current push rod, selects the new next push rod from at least four push rods 23 in the rotation order, controls the next push rod to advance toward the accommodating space 3 to apply force to the rocker device 1, and controls the current push rod to return to its original position.

[0095] If the answer in step S44 is yes, it means that the joystick device 1 has completed a complete circular motion, and the control unit 21 can terminate the testing method of the present invention.

[0096] Specifically, Figure 2 As shown, the test device 2 of the present invention further comprises a storage unit 22 and an alarm unit 24 electrically connected to the control unit 21. In one embodiment, the storage unit 22 stores control rules of the push rod 23, such as the actuation sequence (corresponding to the rotation direction), the moving speed and the advancing distance of the push rod 23. Figure 4 In the aforementioned steps S41 and S42, the control unit 41 selects the current push rod and the next push rod according to the actuation sequence, controls each push rod 23 to advance toward the accommodating space 3 according to the moving speed and the advancing distance, and controls each push rod 23 to return to the initial position according to the moving speed.

[0097] like Figure 2 As shown, the joystick device 1 can be electrically connected to an external electronic device 5, such as a computer or a mobile phone, so that the electronic device 5 receives the electronic signal generated when the joystick device 1 rotates. When the joystick device 1 is placed in the accommodation space 3 of the test equipment 2 and driven by the push rod 23, a corresponding electronic signal will be generated based on the movement. During the operation of the push rod 23, the electronic device 5 captures the electronic signal of the joystick device 1 in every tiny time (such as microseconds or milliseconds), and marks the test track generated by the movement of the joystick device 1 (such as FIG. 5A to FIG. 5E Test track 42 shown).

[0098] In the present invention, the electronic device 5 or the warning unit 24 of the test device 2 can receive and determine whether the test trajectory matches the preset threshold trajectory. If it is determined that the test trajectory does not match the threshold trajectory, for example, the difference is too large or there are too many missing signals in the test trajectory, the electronic device 5 or the warning unit 24 can record the wrong test trajectory, or directly send a warning signal to remind the user that the joystick device 1 may be a defective product.

[0099] See also FIG. 5A to FIG. 5E , is a specific embodiment of a schematic diagram of multiple continuous test actions of the present invention. For ease of understanding, FIG. 5A to FIG. 5E The embodiment of the present invention takes the test device 2 having a first push rod 231, a second push rod 232, a third push rod 233 and a fourth push rod 234 as an example, wherein the angle between each adjacent push rod among the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 is 90 degrees. However, in other embodiments, the number of push rods 23 may be a multiple of four, or any number greater than four, instead of being 1. FIG. 5A to FIG. 5E The following are limited to those shown.

[0100] like Figure 5A As shown, first, the control unit 21 of the test device 2 selects the second push rod 232 among the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 as the current push rod, and controls the current push rod to move toward the accommodating space 3 (i.e., the position of the rocker device 1). After the front end of the current push rod touches the rocker device 1, it can be stressed and tilted to the bottom in the direction of the stress.

[0101] It is worth mentioning that the testing device 2 of the present invention converts the linear motion of the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 into the circular motion of the rocker device 1, thereby testing the rocker device 1, wherein the rocker device 1 tilting to the bottom in one direction can be regarded as a preparatory action before the circular motion, so Figure 5A The control of the second push rod 232 by the control unit 21 can be regarded as a preparatory pushing action.

[0102] exist FIG. 5A to FIG. 5E In the embodiment of the present invention, the rotation direction is preset to be clockwise. Figure 5B As shown, the control unit 21 of the test device 2 then selects the first push rod 231 as the next push rod according to the rotation direction. Then, the control unit 21 controls the next push rod to advance toward the accommodating space 3, so that the rocker device 1 is forced to fall to the bottom in the force direction, and controls the current push rod (i.e., the second push rod 232) to return to its original position.

[0103] When the pushing action of the next push rod and the returning action of the current push rod are completed, the rocker device 1 has completed a quarter of the rotation, and the rocker device 1 leaves the following Figure 5B One quarter of the test trajectory 42 is shown. It is worth mentioning that, since the present invention converts the linear motion of the push rod into the circular motion of the rocker device 1, rather than directly controlling the rocker device 1 to perform circular motion, the test trajectory 42 actually generated by the rocker device 1 will be slightly inward compared to the standard circular trajectory 41. Therefore, as long as the test trajectory 42 of the rocker device 1 can be successfully drawn, and the difference between the test trajectory 42 and the threshold trajectory (such as the standard circular trajectory 41) does not exceed the threshold, the electronic device 5 or the warning unit 24 will identify it as a normal test trajectory 42. On the contrary, if the test trajectory 42 of the rocker device 1 cannot be drawn (for example, the signal is lost or discontinuous), or the difference between the test trajectory 42 and the threshold trajectory exceeds the threshold, the electronic device 5 or the warning unit 24 will identify the rocker device 1 currently being tested as a defective product and issue a warning.

[0104] Then as Figure 5C As shown, after the next push rod (i.e., the first push rod 231) is pushed forward and the current push rod (i.e., the second push rod 232) is returned to its original position, the control unit 21 uses the next push rod as the new current push rod, and selects the fourth push rod 234 as the new next push rod according to the rotation direction. Then, the control unit 21 controls the next push rod (i.e., the fourth push rod 234) to be pushed in the direction of the accommodation space 3, so that the rocker device 1 is forced to fall to the bottom in the force direction, and controls the current push rod (i.e., the first push rod 231) to return to its original position.

[0105] When the pushing action of the next push rod and the returning action of the current push rod are completed, the rocker device 1 has completed half of the rotation, and the following Figure 5C One-half of the test trajectory 42 is shown.

[0106] Then as Figure 5D As shown, after the pushing action of the next push rod (i.e., the fourth push rod 234) and the returning action of the current push rod (i.e., the first push rod 231) are completed, the control unit 21 uses the next push rod as the new current push rod, and selects the third push rod 233 as the new next push rod according to the rotation direction. Then, the control unit 21 controls the next push rod (i.e., the third push rod 233) to push toward the accommodating space 3, so that the rocker device 1 is forced to fall to the bottom in the force direction, and controls the current push rod (i.e., the fourth push rod 234) to return to its original position.

[0107] When the pushing action of the next push rod and the returning action of the current push rod are completed, the rocker device 1 has completed three quarters of the rotation, and the following Figure 5D Three quarters of a test trajectory 42 are shown.

[0108] Then as Figure 5E As shown, after the pushing action of the next push rod (i.e., the third push rod 233) and the returning action of the current push rod (i.e., the fourth push rod 234) are completed, the control unit 21 uses the next push rod as the new current push rod, and selects the second push rod 232 as the new next push rod according to the rotation direction. Then, the control unit 21 controls the next push rod (i.e., the second push rod 232) to push toward the accommodating space 3, so that the rocker device 1 is forced to fall to the bottom in the force direction, and controls the current push rod (i.e., the third push rod 233) to return to its original position.

[0109] When the pushing action of the next push rod and the returning action of the current push rod are completed, the rocker device 1 completes a complete circular motion and leaves the following Figure 5E A circular test track 42 is shown.

[0110] like FIG. 5A to FIG. 5E As shown, when the test device 2 guides the rocker device 1 to move by controlling the push rods 231-234, the electronic device 5 will continuously record the electronic signal generated by the rocker device 1 and mark the corresponding test track 42, thereby, the electronic device 5 or the test device 2 can determine whether the rocker device 1 is a good product or a bad product based on the parameters such as the retraction degree, integrity, and continuity of the test track 42. In addition, when the test device 2 of the present invention performs the above-mentioned actions to perform a circular test on the rocker device 1, no human intervention is required at all, which can effectively reduce the test cost and shorten the test time.

[0111] exist FIG. 5A to FIG. 5E In the embodiment of the present invention, the control unit 21 controls the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 to perform linear motion based on the clockwise rotation direction, so as to make the rocker device 1 perform clockwise circular motion. In other embodiments, the control unit 21 may also control the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 to perform linear motion based on the counterclockwise rotation direction, so as to make the rocker device 1 perform counterclockwise circular motion, instead of using the clockwise rotation direction. FIG. 5A to FIG. 5E The embodiments shown are limited.

[0112] exist FIG. 5A to FIG. 5EIn the embodiment of the present invention, the control unit 21 controls each push rod 231-234 to perform one push action and one return action (except the preparatory push action in the first step), thereby converting the linear motion of the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 into one complete circular motion of the rocker device 1 and performing a good / bad product test. In other embodiments, the control unit 21 can control each of the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 to perform multiple push actions and multiple return actions (for example, two or three times, etc.) according to a predetermined actuation sequence, thereby confirming that the test track 42 engraved by the electronic device 5 is correct, thereby enhancing the accuracy of the test result.

[0113] It is worth mentioning that the control unit 21 can also continuously control each of the first push rod 231, the second push rod 232, the third push rod 233 and the fourth push rod 234 to perform multiple pushing actions and multiple returning actions (for example, ten thousand times or one hundred thousand times) according to a predetermined actuation sequence until the electronic device 5 cannot engrave the correct test track 42 of the rocker device 1. In this way, the test device 2 and the test method of the present invention can also be used to test the service life of the rocker device 1.

[0114] See also Figure 6 , which is a specific embodiment of the push rod arrangement diagram of the test device of the present invention. In one embodiment, the number of the multiple push rods 23 of the test device 2 is a multiple of four, such as four, eight, twelve or sixteen. When selecting two push rods (i.e., the current push rod and the next push rod) for group action (i.e., performing a pushing action and a homing action), the control unit 21 mainly selects two push rods with an angle interval of 90 degrees. In other words, when the current push rod has been determined, the control unit 21 selects a push rod that differs from the current push rod by 90 degrees from the multiple push rods 23 based on the rotation direction as the next push rod.

[0115] exist Figure 6 In the embodiment of the present invention, the testing device 2 has eight putters 23 , including a first putter 231 , a second putter 232 , a third putter 233 , a fourth putter 234 , a fifth putter 235 , a sixth putter 236 , a seventh putter 237 and an eighth putter 238 .

[0116] For example, if the current push rod is the first push rod 231 and the rotation direction is clockwise, the control unit 21 will select the fourth push rod 234 as the next push rod after the first push rod 231 completes the pushing action. For another example, if the current push rod is the seventh push rod 237 and the rotation direction is counterclockwise, the control unit 21 will select the eighth push rod 238 as the next push rod after the seventh push rod 237 completes the pushing action.

[0117] In another embodiment, the number of the plurality of push rods 23 of the test device 2 is four or more, such as four, five, six or seven. When selecting two push rods to be actuated in a group, the control unit 21 mainly selects two push rods that are directly adjacent to each other. In other words, when the current push rod has been determined, the control unit 21 selects the push rod that is directly adjacent to the current push rod from the plurality of push rods 23 as the next push rod based on the rotation direction.

[0118] by Figure 6 For example, if the current push rod is the third push rod 233 and the rotation direction is clockwise, the control unit 21 will select the sixth push rod 236 as the next push rod after the third push rod 233 completes the pushing action. For another example, if the current push rod is the fifth push rod 235 and the rotation direction is counterclockwise, the control unit 21 will select the second push rod 232 as the next push rod after the fifth push rod 235 completes the pushing action.

[0119] By increasing the number of push rods 231-238, the conversion resolution of linear to circular motion can be improved. In this way, when the joystick device 1 is guided by the linear motion of the push rods 231-238 to perform circular motion, the motion trajectory can be more consistent with a perfect circle.

[0120] The testing device and the testing method of the present invention guide the rocker device to perform circular motion by controlling multiple push rods, and can automatically perform signal testing on the rocker device without human intervention, thereby effectively reducing the testing cost and shortening the testing time.

[0121] However, the above is only a preferred embodiment of the present invention, and it cannot limit the scope of the present invention. That is, all equivalent changes and modifications made according to the present invention should still fall within the scope of the patent coverage of the present invention. The present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those familiar with the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should fall within the scope of protection of the claims attached to the present invention.
