Description

V. Description of the invention (1) [Technical field to which the invention belongs] [First, a key test device and method. The Muji keyboard is widely used in various electronic devices to control electronic devices or as peripheral devices for data input, such as: computers, personal computers, direct keyboards for industrial hand-made keyboards, etc. The input function of the electronic equipment, but you W7 7L as a key, thus affecting the operation of the electronic equipment, Bei Zhiyou 4 will be directly tested. At first glance, in the research and development process, it is often necessary to test the durability of the keyboard keys. The test is performed by testing each key of the keyboard, and the method is completed, that is, the person presses the key, and then continues to press the key. This test method is not only costly / D, > 乂 _, and because the force of the manual pressing is different, the test quality of the key cannot be guaranteed. j If you do not use different types of keyboards, such as mechanical contact A, you should have a membrane-type keyboard when testing multiple pressures on both of them. m Μ VI VI ^ ^, do not use this method to test, because it will be manually pressed. It is difficult to pinch the drought, and the chance of misjudgment is greatly increased. Another conventional device and method for testing the keys such as 20000 ^ 6 ^ Chinese Patent Publication No. 1 257241 and June 2000 ^ Kai

^.) ^, 1 258034 ^^, ##, pLC L0glC Cntr0ller) The controller controls the cylinder to actuate, and the drive mechanism moves the compression test mechanism in a shape of Λ Γ to suppress β movement, However, this kind of button test set is due to the PLC control state and the y-axis shift driver.

As a result, the cost of testing is too high. And when testing the keyboard of the mobile phone, such as yttrium, car, and V, if the key test device and method are used, 200411375 V. Description of the invention (2) ^ The control unit of the axis displacement drive mechanism is programmed, The keyboard requires different programs, and the operation process is complicated. Comparison of different $ knowledge technology ’The key test device of the present invention is used to test the reliability of the key, the operation is simple, and the test cost is low. [Summary of the Invention] An object of the present invention is to provide an easy-to-use key test method. Another object of the present invention is to provide an easy-to-use key test: a key test device for keyboard durability of electronic device keys: Machine i ΐ two test institutions, a main control device and a mounting plate.

Among them, stand leg 233 It can be integrally formed or recognized on the base 231 by welding or gluing to set up the holder 235 and make the holder 235 a distance from the base 231 and the distance can be adjusted. Among them, the holder has 2 arms and 35 arms ^ The Γ-shaped π-shaped bracket is detachably mounted on # by means of a nail. The holding post 237 is mechanically set on the base 231. It is sadly used to hold the keyboard under test, and it is provided with a hole. (Unmarked =. The keyboard under test is through a nail (not marked) corresponding to the hole in the plurality of holding posts 237 It is fixed on the base 231. The reset device 25 Ϊ ^ 3 t or bonding is mechanically provided on the holding mechanism 23 for resetting the month J [pressed cylinder 21 3, and this reset message will pass feedback 200411375 V. Description of the invention (5) The signal detection circuit is transmitted to the main control device 1 0. The mounting plate 30 is detachably mounted on the holding frame 235 in a detachable manner, such as a nail, and is provided with a plurality of mounting holes 31 -The size of the mounting hole 31 is slightly larger than that of the terminal element of the terminal element group 21.1, so that the terminal element of the terminal element group 2 n can pass therethrough and is mechanically fixed in the mounting hole 31, and The arrangement of the relative positions of the plurality of mounting holes 31 corresponds to the arrangement of the test keys of the keyboard under test, so that the pneumatic component group can accurately align the pressing position with the keyboard under test through the mounting plate 30, so that the The key test device 1 0 0 can be used to test a keyboard with a variety of different key arrangements by replacing different mounting plates 3 0. In conjunction with the process, it is set to 10 to read and activate. If the control surface parameters, test editing Key setting, If the test is over, please test the effect of the stream master control. If it is, use the number of the set method. If it is a valid component group, it is shown in the second figure, which is the relative of the key test method of the present invention. The control software information can be written and stored in the above for execution. Among them, step 3 0 0 judges whether the start key is invalid. Then proceed to step 3 1 0 to further judge that the edit key is valid then proceed to step 320 to set all parameters. This process board 11 Edit button 11 3 The process of setting the test parameters, which can be read from the LCD display 111, the main | white &amp; ', including the test moving speed, the number of tests, the output mode, and the alarm party 11 is invalid and returns to the beginning . If it is judged in step 300, step 330 is executed, that is, controlled by the main control device 10 = keys of the keyboard are tested one by one, and step 3402 = one round of testing. y Further test whether the cylinder 213 is in step 350

Mode &quot; Mode, if the judgment result is', then proceed to step = &quot; Auto 115 alarm until the test action is stopped, if not $ 'Alarm by alarm, stop the test at the same time' and then judge at step 430 = valid, If the right judgment result is yes, then go to step 44. Otherwise, go to the police and stop the test. Return to step 4 1 0. The steps 300, 310, and 32 in the above-mentioned private practice mainly fulfill the functions of “reliance.” Here you can set the total number of tests, the test speed, and the alarm mode and other parameters. In the present invention, there are two types of tests: simultaneous motion and rotary motion, in which uniform motion means that the plural cylinders are operated together, and that the plural cylinders act in sequence. All the test actions are only performed by pressing the control surface s, the stop key 113 ', and no programming action is required. Editor

In summary, the present invention is in accordance with the requirements of the invention patent application. &quot; Disclosed above are only the best J Shi U of the present invention
