Description

Technical Field

[0001] This utility model relates to the field of keyboard testing technology, and in particular to a testing tool for testing magnetic axis keyboard keys. Background Technology

[0002] In the field of keyboard manufacturing and quality control, especially for magnetic axis keyboards with extremely high actuation precision requirements, key function and durability testing is a key step in ensuring product quality. Currently, there is a common keyboard testing device on the market. It typically uses multiple manually adjustable probes set up inside a test platform. Before use, the tester needs to move and fix the position of each vertical bar one by one according to the key layout of the keyboard under test, aligning it with a specific key on the keyboard. After the device is started, these vertical bars move vertically up and down under the drive mechanism to simulate repeated pressing tests of the keyboard keys by a human hand.

[0003] However, this traditional testing device has obvious drawbacks in practical applications and cannot meet the needs of efficient and comprehensive testing of magnetic axis keyboards. The main drawbacks are: First, the debugging process is cumbersome and inefficient: Since the key layout, number of keys and size of different keyboard models are different, after changing the keyboard model being tested, the testers must spend a lot of time manually positioning and locking each vertical bar again. This alignment process is not only cumbersome to operate, but also seriously slows down the production cycle. Second, insufficient test coverage hinders comprehensive evaluation: The limited number of vertical bars in this type of device typically only covers some frequently used keys on the keyboard. This results in a large number of keys not being tested simultaneously, creating blind spots in quality inspection. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1: Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a testing tool for testing magnetic axis keyboard keys, including a test platform 100, a multi-axis driver 110 arranged on the top of the test platform 100, and a keyboard body 300 arranged in the lower inner part of the test platform 100. The multi-axis driver 110 is the core actuator for realizing test actions. It is preferably a three-axis (X, Y, Z) Cartesian coordinate robot, also known as a linear module or gantry structure. The driver is driven by a high-precision servo motor or stepper motor and the transmission is achieved through a ball screw or synchronous belt to ensure that the motion process is smooth, accurate and low noise.

[0027] The multi-axis driver 110 is rigidly connected to the board 210 through its vertical output end. It is mainly responsible for driving the entire test component 200 to perform repeated and controllable pressing and lifting movements in the vertical direction. Its motion accuracy, repeatability, and speed stability directly determine the reliability of the test results. Through program control, the driver can accurately set the pressing stroke, speed, dwell time, and total number of test cycles, thereby simulating various human hand operation scenarios from gentle to fast, and meeting the requirements of magnetic axis keyboards under different test standards. Test component 200 is located at the drive end of multi-axis driver 110 and is also located directly above keyboard body 300. The test assembly 200 includes a plate 210 located below the drive end of the multi-axis driver 110. The plate 210 has multiple slots 211 arranged in a rectangular array inside. A spring rebounder 216 is arranged above the inside of the slots 211, and a test rod 212 is fixedly connected to the lower part of the spring rebounder 216.

[0028] When personnel need to perform key testing on the keyboard, the keys are first placed in the test platform 100 and below the board 210. Then, the multi-axis driver 110 can drive the board 210 to be above the keyboard and move vertically downward. First, the lower end of the detection rod inside the board 210 contacts the keyboard key. Since there is a gap between the keyboard keys, the contact rod that contacts the key will be pushed upward and squeeze the spring return 216. The test rod 212 that is between the keycap gaps is in the initial state. Then, after the multi-axis driver 110 drives the board 210 to rise, the spring return 216 will drive the upper end of the test rod 212 to rebound downward. The test rod 212 that was originally in contact with the key will extend downward, and the lower end surface will be lower than the test rod 212 that is not in contact with the key. The aforementioned spring-loaded spring 216 is the core elastic element that gives each test rod 212 independent adaptive capability, used to achieve two-stage positioning of the test rod 212: that is, it can stably retract and lock when pressed by external force; under the next pressing cycle or a specific reset signal, it can quickly pop out and lock back in the extended position. In this embodiment, the spring-loaded spring 216 is in a compressed state, so it only needs to be pressed to open the pop-out mode. The spring-loaded spring 216 is mainly composed of a shell, a spindle, a helical spring, and a reversing mechanism consisting of a sliding pin and a special-shaped slot. The spindle is fixedly connected to the test rod 212 and is the core component of the movement. The helical spring is sleeved on the outside of the spindle to provide energy storage and reset power. The reversing mechanism is the key to realizing the self-locking function. Usually, one or more sliding pins are set on the spindle, and a specific annular or helical special-shaped slot is provided on the inner wall of the shell. The trajectory of the slot is designed to guide the sliding pin to make lateral displacement when it reaches a specific position, thereby realizing the switching between the locking and unlocking states of the spindle. The specific operation is as follows: When the lower end of the test rod 212 contacts the keycap and is subjected to continuous pressure, the spindle is pushed into the shell of the spring return 216, compressing the coil spring. During this process, the sliding pin on the spindle moves along the irregular groove trajectory on the inner wall of the shell. When pressed to a certain stroke, the sliding pin slides into the locking groove of the groove under the combined action of the spring pressure and the groove contour, so that the test rod 212 is mechanically locked in the retracted state. At this time, even if the reaction force of the keycap disappears, the test rod 212 will not pop out. When all test rods 212 need to be reset to prepare for the next test or for height locking, the multi-axis driver 110 drives the plate 210 to perform a small-amplitude, rapid secondary downward pressure. This downward pressure instantly dissipates the balance of the sliding pin in the locking groove, causing it to slide out of the groove and into the release channel of the slot. At this moment, the elastic potential energy of the compressed helical spring is released instantaneously, pushing the spindle to move rapidly downward until the sliding pin moves to the lower limit point of the slot trajectory and is locked again. Thus, the test rods 212 return to their maximum extended state, completing one working cycle. Specifically, the test assembly 200 also includes a first piston 215 disposed on the surface of the test rod 212. The first piston 215 is located in the groove 211 and its edge is in contact with the groove wall.

[0029] When the aforementioned plate 210 drives the test rod 212 to contact the keyboard, the lower end of the test rod 212 is subjected to pressure, which will drive the first piston 215 to move upward inside the groove 211. The first piston 215 will then discharge the excess gas in the upper part of the groove 211 to the outside, so that the air pressure in the groove 211 remains constant, and at the same time, it can also lay the foundation for the subsequent locking operation of the test rod 212. Specifically, a vertical rod 213 is inserted inside the first piston 215, and both ends of the vertical rod 213 are fixedly connected to the inner wall of the groove 211.

[0030] To ensure the absolute verticality and stability of the test rod 212 during its up-and-down movement and to prevent it from wobbling or shifting within the groove 211 and exerting lateral force on the magnetic shaft, a vertical rod 213 is inserted inside the first piston 215. Both ends of the vertical rod 213 are fixedly connected to the inner wall of the groove 211, forming a robust guide rail that allows the first piston 215 to maintain vertical movement.

[0031] Specifically, the lower end of the test rod 212 is fitted with a protective sleeve made of silicone.

[0032] Considering that the test stick 212 is a component that comes into direct contact with the keycap, in order to prevent the hard test stick 212 from wearing down or even scratching the surface of the keycap during long-term and repeated testing, a protective sleeve made of silicone is fitted on the lower end of the test stick 212. The silicone material is soft, elastic and has a moderate coefficient of friction, which can effectively protect the surface of the keyboard keycap and prevent scratches or wear. Example 2: Reference Figures 3-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, one end of the pipe 220 is threadedly connected to a lead screw 221, and a second piston 222 is fixedly connected to the surface of the lead screw 221 through a bearing seat.

[0034] After the plate 210 rises and the test rod 212 that contacts the button is ejected downward by the springback device 216, the operator can hold the lead screw 221 and rotate it. At this time, the second piston 222 will pull the lead screw 221 in the direction of the lead screw 221 to draw gas from the multiple rows of tanks 211 through the pipe 220, so that the tanks 211 are in a negative pressure state. Thus, the height of all test rods 212 can be limited.

[0035] Specifically, the trough 211 is arranged in multiple rows, with multiple troughs 211 in each row. The multiple troughs 211 in the same row are interconnected. A pipe 220 is fixedly connected to one side of the plate 210. The surface of the pipe 220 is connected in a straight array with a number of air pipes that are the same as the number of rows of troughs 211. The air pipes are connected to the troughs 211 in the plate 210.

[0036] The above design achieves synchronous adjustment, greatly improving the ease of operation for personnel.

[0037] Specifically, a resistance ring 214 is provided above the first piston 215, and the resistance ring 214 is made of rubber.

[0038] The aforementioned resistance ring 214 has a diameter that is wider at the top and narrower at the bottom. The resistance ring 214 is not connected to any structure; it is only positioned above the first piston 215. When the first piston 215 is ejected downward by the rebound device 216, due to the small contact area between its lower part and the inner wall of the groove 211, it can fall to the surface of the first piston 215 by its own weight. When the inside of the groove 211 is under negative pressure, in order to prevent the first piston 215 from being sucked upward, the upper end face of the resistance ring 214, which has the same diameter as the inner wall of the groove 211, can increase the resistance between the resistance ring 214 and the inner wall of the groove 211, thereby achieving the effect of blocking the position of the first piston 215. During use, the operator first fixes the keyboard body 300 to be tested inside the test platform 100, ensuring it is stably positioned directly below the board 210. After starting the device, the multi-axis driver 110 drives the entire test assembly 200 to descend. During the descent, when the silicone protective sleeve at the lower end of the test rod 212 contacts the keyboard keycaps, the reaction force of the keycaps pushes the test rod 212 upward, compressing the spring return mechanism 216. Simultaneously, the first piston 215 fixed to the test rod 212 moves synchronously upward along the vertical rod 213 within the groove 211, expelling the gas from the upper part of the groove 211 to accommodate this compression stroke. Due to the gaps between the keyboard keycaps, the test rod 212 that is not in contact with the keycaps will remain in its initial extended state. After the initial contact positioning is completed, the multi-axis driver 110 drives the plate 210 to rise. At this time, all the compressed springs 216 begin to release their elasticity, pushing the test rods 212 below them to reset downwards. The test rods 212 that were previously in contact with the keycaps extend downwards under the action of the springs 216, and their lower end face will be lower than those test rods 212 that were not in contact with the keycaps and were always in the initial position. This allows the lower end face of all test rods 212 to automatically adapt to the undulating layout of the keyboard keycaps and form a contact plane that matches the contour of the keycaps. After all test rods 212 have completed their adaptive reset, the operator can rotate the lead screw 221. The rotation of the lead screw 221 will pull the second piston 222 connected to it to move within the pipe 220. Through the pipe 220 and the exhaust pipes connected to it, the gas in all the interconnected tanks 211 in the same row is extracted simultaneously, so that a stable negative pressure state is formed inside the entire system. Under this negative pressure, all the first pistons 215 have a tendency to be drawn upward.

[0039] At this point, the rubber resistance ring 214 positioned above the first piston 215 plays a crucial role. It falls naturally under its own weight and adheres to the upper surface of the first piston 215. Because its upper end diameter matches the inner wall of the groove 211, it generates significant frictional resistance against the groove wall under negative pressure. This resistance effectively prevents the first piston 215 from being drawn upwards, thus firmly locking all the test rods 212 at their respective suitable height positions. Finally, the multi-axis driver 110 can then, according to a preset program, drive the entire pre-shaped test assembly 200 to repeatedly and precisely cycle through vertical pressing and lifting, efficiently, comprehensively, and non-destructively automating the testing of all keys on the entire keyboard.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
