[0037] In this embodiment, the touch panel can be various automotive interior products including touch switches, for example, touch front interior lamps, touch rear interior lamps, intelligent surfaces, touch display panels, etc., which can meet the technical requirements of different products.

[0038] In this embodiment, the pressing device includes: a SCARA robot and a test copper bar; the test copper bar is arranged on the SCARA robot; the host computer is electrically connected to the SCARA robot, and the host computer is adapted to control the SCARA robot to drive the test copper bar to press the touch panel to be detected; the detection device includes: a high-precision pressure sensor electrically connected to the host computer; the high-precision pressure sensor is arranged on the test copper bar; the high-precision pressure sensor is adapted to detect the pressing pressure when the test copper bar presses the touch panel, and send the detected pressure data to the host computer. The high-precision pressure sensor is fixed on the SCARA robot through a bracket, and the test copper bar is connected to the pressure sensor to simulate the contact of a human hand with products such as lamps or intelligent surfaces with touch switches. When the SCARA robot drives the test copper bar to move downward, a certain pressure will be applied to the surface of the touch switch to make the switch conduct, and the conduction current of the lamp or intelligent surface product is transmitted to the PC program (host computer) through the current acquisition module to determine whether the test result is qualified. The SCARA robot selected is a Delta Electronics four-axis horizontal articulated robot with a maximum working radius of 400 mm and a repeatability accuracy of ±0.01 mm, meeting the accuracy requirements of motion control. The range of the high-precision pressure sensor is 0.1 - 3 KN, the accuracy is 0.1%, the shape is small and the installation is convenient. The equipped pressure sensor digital display has a display accuracy of 0.01% and is connected to the PC through the RS-232 serial port.

[0039] In this embodiment, the host computer is electrically connected to the robot controller of the SCARA robot. The host computer can send control signals to the robot controller, and the robot controller controls the SCARA robot to work. A regulated power supply can be set to supply power to the SCARA robot and the digital display of the pressure sensor. A programmable power supply is set to supply power to the workpiece to be detected (the touch panel to be detected) and the host computer.

[0040] In this embodiment, the detection device includes: a current acquisition module; the current acquisition module is electrically connected to the host computer and is also electrically connected to the touch panel to be detected; the current acquisition module is adapted to detect the current when the test copper bar presses the touch panel and send the detected current data to the host computer. With robot control as the main part, combined with functions such as pressure sensing acquisition, current acquisition, data transmission and processing, and human-computer interaction, the automatic detection of the touch switch performance of the automotive interior lamp is realized.

[0041] In this embodiment, the high-precision pressure sensor is electrically connected to a digital display of the pressure sensor; the digital display of the pressure sensor is adapted to display the pressure data detected by the high-precision pressure sensor.

[0042] In this embodiment, the host computer is adapted to control the pressing device to press the touch panel to be detected, that is, the host computer is adapted to control the pressing device to reach the touchable point of the touch panel to be detected, set the horizontal coordinates (X, Y), the Z-axis of the pressing device moves downward, apply a downward pressing force at the touchable point, and adjust the up and down coordinates of the Z-axis through the pressure value fed back by the detection device to determine the point coordinates (X, Y, Z) to be detected at the touchable point.

Adjusting the Z-axis pressure value can control the surface force of the product assembly to be greater than 200N, and the touch operating force is within the range of (4 ± 0.8)N.

[0045] (2) Write an automated control script. According to the parameters determined in advance in (1), set the touch points (X, Y, Z) in the program script. Refer to the product test technical requirements and set data such as the distance between the Z-axis of the robot and the product, acceleration, pressing time, and number of presses. The PC executes the automated script to control the robot to apply pressure to the touch panel. When the Z-axis reaches the specified pressing point, it sends an in-place signal to the PC through the RS-232 interface.

[0046] (3) Data collection and analysis. After the robot arrives at the position, the PC collects the pressure value of the pressure sensor digital display and the current value of the current module, analyzes whether the collected pressure value and current value meet the conditions during normal operation of the product, generates a test result, and the program records the test result and outputs a test report. It can be achieved that: 1) a force of more than 200 N can be applied to the surface of the touch-type product assembly; 2) the operating force of each contact character on the touch panel is controlled at 4 ± 0.8 N; 3) the accuracy of motion control reaches 1 mm / s. Move the test copper rod towards the touch area at a speed of 1 mm / s from a distance of 10 mm from the touch surface until a touch signal response is obtained; 30,000 times of durability test at room temperature; 4) automatically generate a test report.
