[0050] Further references Figure 8The mobile device 330 includes a second driving member 331, a third base plate 338 fixedly connected to the output end of the second driving member 331, and a third driving member 337 fixedly connected to the third base plate 338. A test finger 321 is fixedly connected to the output end of the third driving member 337. In this embodiment, two third driving members 337 and two test fingers 321 are provided, respectively used to test the washing machine touch panel 4 on the two limiting slots 210.

[0051] Specifically, the moving device 330 also includes a second slide rail 333, a pair of second columns 341, and a second base plate 342. The pair of second columns 341 are symmetrically arranged about the fixed platform 200. The second columns 341 are fixedly connected to the fixed base plate 103 by screws, and both ends of the second base plate 342 are fixedly connected to the pair of second columns 341 by screws. The second driving member 331 is arranged parallel to the second slide rail 333 and is fixedly connected to the second base plate 342 by screws. A third slider 332 is fixed on the output end of the second driving member 331, and a fourth slider 334 is slidably arranged on the second slide rail 333. The third base plate 338 is connected to the third slider 332 and the fourth slider 334 respectively. When the second driving member 331 drives the third base plate 338 to move, the second slide rail 333 enables the third base plate 338 to move more stably.

[0052] Furthermore, two third driving members 337 are symmetrically connected to the third base plate 338 and are arranged perpendicularly to the second driving member 331. The test module 320 also includes fasteners 322, to which the test finger 321 is fixedly connected. In this embodiment, there are two fasteners 322, which are respectively fixedly connected to the output ends of the two third driving members 337 and move under the drive of the two third driving members 337, thereby driving the test finger 321 to perform the test operation.

[0053] Preferably, the test finger 321 is made of copper rod. Copper rod is relatively soft, which can effectively avoid damage to the screen and mechanical contacts. Furthermore, copper rod is conductive, allowing it to replace human fingers when testing capacitive touchscreens. Preferably, the second drive component 331 is a single-axis movement module, and the third drive component 337 is a cylinder.

[0054] In addition, the test module 320 also includes a buffer 323 and a limiting bolt 324, both of which are fixedly connected to the third base plate 338. Specifically, a first side plate 339 is also fixed to the third base plate 338, and the buffer 323 and the limiting bolt 324 are both connected to the first side plate 339 by screws. The buffer 323 can abut against the fastener 322 to cushion the movement of the test finger 321. Specifically, the buffer 323 abuts against the fastener 322, making the downward pressure gentler. When the test finger 321 moves to its position, the limiting bolt 324 abuts against the fastener 322 to prevent the test finger 321 from pressing down excessively and damaging the washing machine touch panel 4.

[0055] The control principle of this washing machine touch panel function testing device during use is as follows: Figure 9 As shown, and also refer to Figure 2 The operator presses the power button 113 to start the device. The fourth drive component 121 retracts under the control of the controller 115, driving the door panel 120 to lift and open the box opening 102. Then, the controller 115 controls the first drive component 240 to drive the fixed platform 200 to move to the bottom edge of the box opening 102, where a material handling device (not shown) is placed. The operator then takes out two washing machine touch panels 4 to be tested from the material handling device, places the two washing machine touch panels 4 in a pair of limiting slots 210 respectively, and rotates the second limiting component 230 to fix the washing machine touch panels 4 in the limiting slots 210. At this time, the washing machine touch panels 4 are electrically connected to the pins 203. Then the operator presses a pair of start buttons 112 with both hands, and the controller 115 controls the first drive unit 240 to drive the fixed platform 200 to move to the test component 3; if the first sensor 122 detects an object in the box opening 102 or the second sensor 205 does not detect the washing machine touch panel 4, the device stops operating and displays a warning message; if the first sensor 122 detects no object in the box opening 102 and the second sensor 205 detects the washing machine touch panel 4, the fourth drive unit 121 drives the door panel 120 to fall and close the box opening 102, so that the silent box 100 maintains a silent environment.

[0056] During the testing process, this washing machine touch panel function testing device... Figure 3 and Figure 4As shown, firstly, the fifth driving component 222 drives the second limiting block 224 to move and abut against the washing machine touch panel 4, thereby further fixing the washing machine touch panel 4. During the test, the first driving component 240 drives the washing machine touch panel 4 to move along the X direction in the figure, the second driving component 331 drives the test finger 321 to move along the Y direction in the figure, and the third driving component 337 drives the test finger 321 to move along the Z direction, thus achieving the purpose of the test finger 321 touching and pressing any position on the washing machine touch panel 4. During the test, the camera 301 located above the washing machine touch panel 4 will take pictures of the screen display content during the test and transmit them to the host computer 304 for analysis and comparison. In addition, the sound emitted by the buzzer on the washing machine touch panel 4 is detected by the sound level meter 351 located below the fixed platform 200, and the relevant data will also be transmitted to the host computer 304. After comparing the received test data with the normal data, the host computer 304 will display the test result as "PASS" or "FAIL" on the integrated display screen of the host computer 304.

[0057] After the test, the controller 115 controls the fourth drive unit 121 to retract, lifts the door panel 120 to open the box opening 102, and then controls the first drive unit 240 to drive the fixed platform 200 to move to the bottom edge of the box opening 102, waiting for the operator to replace the washing machine touch panel 4.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
