Technical Field

[0001] The present invention relates to the technical field of rocker testing, and particularly relates to a rocker testing device and method. Background Art

[0002] In existing electronic devices, the rocker is one of the main operation control devices in the control system. The electrical and mechanical performance of the rocker determines the accuracy of the control. Therefore, the electrical and mechanical tests of the rocker are very important. Currently, the conventional testing devices have low ability to test and inspect the performance of the rocker, and the testing process and structure are relatively cumbersome.

[0003] There are two ways to test the rocker: manual testing and automated testing. The manual testing method has low efficiency, is greatly interfered by human factors, has poor controllability of the testing conditions, and the obtained test results often have large differences, so the reference value is not high; the automated testing equipment has a complex structure, and the automated testing tooling for clamping the rocker has difficulties in installation and disassembly, and it is difficult to detect rockers of different models through a set of tooling, resulting in low testing efficiency when facing the testing requirements of batch production.

[0010] The rocker feedback device includes a first support plate and a second support plate located on both sides of the driving device, and is equipped with a limit block to prevent the rocker driving device from hitting the body when not calibrated to the zero position. The first support plate is equipped with a first position zeroing sensor for detecting the angle of the rocker rotation device, and the second support plate is equipped with a second position zeroing sensor for detecting the rocker driving device.

The size of the mounting plate 3 can be replaced according to the size of the rocker. In the figure, 6 is the rocker to be tested, and 6-1 is the metal operating rod of the rocker.

[0019] When testing the rocker, the rocker 6 is installed directly above the mounting plate 3 of the rocker fixing device, the metal rod 6-1 of the rocker 6 is placed in the direction of the second rotating motor 14, the pressing block 5 is placed directly above the rocker 6, and the locking mechanism 4 is used to press the pressing block 5 to fix the rocker 6. The locking mechanism 4 can adjust the fixing degree according to the size of the rocker, so as to replace different models of rockers during production. Further, the communication transfer module 12 of the rocker is fixedly connected to the mounting plate and is communicatively electrically connected to the rocker 6 and the signal acquisition device of the control box 1.

[0020] The first rotating motor 11 of the rocker driving device is installed on the control box 1. The center of the first turntable 16 is fixed to the output shaft of the rotating motor 11 through a transfer. The pushing rod 15 is fixed to the side of the turntable 16 with bolts and is perpendicular to and intersects the metal operating rod 6-1 of the rocker 6. Driven by the first rotating motor 11, the rocker 6 can move to the corresponding angle according to the demand to complete the main process of the test.

[0021] The second rotating motor 14 of the rocker rotating device is installed on the control box 1. The center of the second turntable 10 is fixed to the output shaft of the second rotating motor 14 through a transfer. The rocker fixing device is located on the support column 17 and is fixed with bolts. Driven by the second rotating motor 14, the rocker fixing device and the fixed rocker 6 can be rotated to the corresponding angle according to the requirements to complete the corresponding position change of the rocker in the X-axis and Y-axis planes.

[0022] The first support plate 8 and the second support plate 18 of the rocker feedback device are located on both sides of the rocker driving device and are fixed to the control box 1 by bolts. Limit blocks 9 for limiting the rocker driving device are installed on the support plate 8 and the support plate 18 to prevent the rocker driving device from hitting the body when not calibrated to the zero position. At the same time, a first position zeroing sensor 7 is fixed on one side of the top of the support plate 8 by an L-shaped sheet metal part, and a second position zeroing sensor 13 is installed on the other support plate 18. The first position zeroing sensor 7 detects the angular position of the rocker rotating device, and the second position zeroing sensor 13 detects the angular position of the rocker driving device. The first position zeroing sensor 7 and the second position zeroing sensor 13 are electrically connected to the control module of the control box 1. The touch display screen 2 is installed on the control box 1 as the host computer to control the movement of the rocker driving device and the rocker rotating device, and feedback the positions of each device in the system through the position zeroing sensor and return to the initial position for the next test cycle. A signal acquisition module for real-time acquisition of rocker output value data, a data storage module for storing rocker output value data, and a control feedback module for comparing it with a preset value to judge whether the rocker output value meets the performance requirements are also installed inside the control box 1.

[0023] In the present invention, an industrial computer or a touch display screen is used as the host computer, and a single-chip microcomputer, DSP, etc. are used as the slave computer to control the rocker test device. With the present invention, performance testing and production testing of the rocker can be carried out. First, the tester places the rocker on the mounting plate, uses a pressing block to place it directly above the rocker and fixes it by tightening the locking device. Then, click the parameter setting on the main page of the touch display screen to set the parameters of the tested rocker, including the range of the swing angle of the rocker operating rod and the range of the output voltage amplitude.

[0024] Performance testing refers to detecting the situation of the rocker under long-term life tests. When performing rocker performance testing, the rocker will record the voltage amplitude range of each swing angle during the test and perform counting and accumulation after each cycle (one cycle is 360°). In the performance testing mode, the data obtained from each swing angle test of the rocker will be displayed in the form of a waveform on the touch display screen, which is convenient for the tester to monitor the rocker test process. The rocker test device will detect whether the data of each swing angle conforms to the set ideal value range. The data that does not meet the requirements will be recorded on one side of the touch display screen. By recording the swing angle range and voltage amplitude range that exceed the set ideal value, the obtained test data can be provided to technicians for further solutions. In the performance testing mode of the rocker test device, the strength of the structural parts of the rocker can be tested, including whether the service life of the used spring meets the design requirements and the wear situation between the structural parts in contact with the moving parts. Based on the data obtained from the performance testing, the rocker parts can be rectified and further tested to improve the quality and meet the requirements of the rocker.

[0025] When conducting production tests, the host computer sends a start command to the slave computer of the joystick test device. After receiving the start command, the communication module on the joystick is electrically connected to the signal acquisition device. At the same time, the rotary motor that drives the joystick drive device drives the push rod to contact and move with the metal rod of the joystick. The joystick drive device and the joystick rotation device will perform a self-test for the first zero-position calibration during the initial process, so that the positions of all devices of the joystick test device are at the set initial positions during the test, to ensure the accuracy and reliability of joystick testing. After receiving the command sent by the host computer, the joystick rotation device will rotate successively according to different set angles to collect the voltage amplitude change data of the joystick in different directions. The joystick test device operates in coordination with the joystick drive device and the joystick rotation device according to different commands sent by the host computer, thereby realizing the test process of the joystick.

[0026] When testing the joystick, the tester first places the joystick on the mounting plate part, places the pressing block directly above the joystick and fixes it by using the locking device to press the pressing block. Click on the parameter setting on the main page of the touch display screen to set the parameters of the joystick to be tested, including the range of the swing angle of the joystick operating rod and the range of the output voltage amplitude. Then return to the main page and click on the corresponding production test. The host computer sends a start command to the slave computer of the joystick test device. After receiving the start command, the communication module on the joystick is electrically connected to the signal acquisition device. At the same time, the rotary motor that drives the joystick drive device drives the push rod part to contact and move with the metal rod of the joystick. The joystick drive device and the joystick rotation device will perform a self-test for the first zero-position calibration during the initial process, that is, when the device receives the command sent by the touch display screen, the position zeroing sensor will detect the relative position angles of the joystick rotation device and the joystick drive device with respect to the device in the first time, and whether they conform to the preset position angles. If they do not conform, after being judged by the feedback control module, the data will be transmitted to the host computer, and the host computer will send a command to drive the joystick rotation device and the joystick drive device to run to the starting position angle during the test, so that the positions of all devices of the joystick test device are at the set initial positions during the test, to ensure the accuracy and reliability of joystick testing. After receiving the command sent by the host computer, the joystick rotation device will rotate successively according to the set angles to collect the voltage amplitude change data of the joystick in different directions. The joystick test device operates in coordination with the joystick drive device and the joystick rotation device according to different commands sent by the host computer, thereby realizing the test process of the joystick.
