[0024] Example: See Figures 1 to 6 In an embodiment of the present invention, an automated testing system for mobile terminal production includes a positioning and conveying component 1, a loading robot 2, and a rotating loading component 3, wherein the positioning and conveying component 1 can convey and position the mobile terminal to be tested, and then the loading robot 2 grabs the mobile terminal and sends it to the rotating loading component 3, the rotating loading component 3 includes a base plate, a turntable 31, a carrier plate 32 and a detection head 36, wherein the turntable 31 is rotatably arranged on the base plate and has power, and a carrier plate 32 is provided on the turntable 31 for receiving the mobile terminal, and a detection head 36 is connected to one side of the base plate by a mounting arm 35, and the detection head 36 can perform touch testing on the mobile terminal in a gentle feeding manner.

[0025] Among them, the loading robot 2 performs grabbing, moving, and lowering actions in a fixed trajectory. Therefore, after the mobile terminal is positioned on the positioning and conveying component 1, the loading robot 2 can more accurately grab and lower the mobile terminal.

[0026] Among them, Figure 3 The positioning and conveying assembly 1 includes a mounting base 11, a rotating wheel 12, a mounting frame 15 and a rotating positioner 16, wherein the mounting base 11 is symmetrically arranged, and two symmetrically arranged rotating wheels 12 are rotatably connected to the mounting base 11. A conveyor belt 13 is transmission-connected between the two rotating wheels 12, and the two conveyor belts 13 jointly support a loading plate 14.

[0027] In addition, a mounting frame 15 is fixed on both mounting seats 11, and a rotation positioner 16 is fixed at the four corners of the mounting frame 15. A positioning arm 17 is fixed to the rotation output end of the rotation positioner 16. A lifting cylinder is also provided between the two mounting seats 11, and a lifting plate 18 is fixed to the output end of the lifting cylinder.

[0028] The width of the lifting plate 18 is smaller than the distance between the two conveyor belts 13 so that the lifting plate 18 can move up and down in the space between the two mounting seats 11 without being blocked;

[0029] The loading plate 14 is used to place the mobile terminal to be tested. Specifically, the mobile terminal is a mobile terminal with a screen.

[0030] The rotary positioner 16 can be a device with a rotary output end such as a motor or a rotary cylinder.

[0031] like Figure 6 The micro-movement of the four positioning arms 17 can assist the mobile terminal to be detected in fine-tuning its position.

[0032] As a preferred embodiment, the upper surface of the lifting plate 18 has a plurality of positioning protrusions, and the lower surface of the loading plate 14 has a plurality of positioning recesses.

[0033] In this embodiment, Figure 2 The turntable 31 has two through slots symmetrically formed thereon, the carrier plate 32 is slidably arranged above the through slots, and a lead screw mechanism 33 for driving the carrier plate 32 to move is arranged below the through slots.

[0034] The screw mechanism is an existing screw-nut substructure, which will not be described in detail here. The screw mechanism 33 can realize the movement of the carrier plate 32, and the carrier plate can realize the positioning load of the material carrier. Specifically, the upper surface of the carrier plate also has multiple positioning protrusions.

[0035] As a preferred embodiment, a positioning cylinder 34 is further fixed on the base plate.

[0036] like Figure 4 The detection head 36 includes a detection chamber 361, a conduit 362, a touch rod 365 and a touch head 366, wherein a T-shaped hole is opened in the middle of the detection chamber 361, and a conduit 362 is embedded in the lower part of the T-shaped hole. A touch rod 365 is slidably arranged in the conduit 362, a piston is set at the top of the touch rod 365, and a touch head 366 is set at the bottom of the touch rod. One side of the conduit 362 is also connected to an air supply pipe 364 so that an external air supply device can supply or extract air to the conduit 362. An overflow head 363 is fixed to the top of the conduit 362, and a plurality of overflow holes are opened on the overflow head 363.

[0037] In addition, a flexible touch pad is provided at the bottom of the touch head 366, and a pressure sensor is embedded in the touch head 366. The pressure sensor and the external air supply device are electrically connected to the controller. The controller is configured as follows: when the touch head 366 is used for touch detection, the touch rod 365 first performs free fall motion, and then when the pressure sensor detects pressure, it controls the external air supply device to supply air.

[0038] The free-fall motion enables the touch head to quickly and gently contact the mobile terminal to be tested. After that, air is supplied through an external air supply device to make the touch rod move further downward so as to make close contact with the mobile terminal to achieve touch detection.

[0039] In order to further improve the softness of the touch of the touch head, in this embodiment, an outer ring 367 is fixed under the detection chamber 361, and a damping adjustment component 368 is provided on the inner side of the outer ring 367. The damping adjustment component 368 is configured as follows: when the touch head 366 is used for touch detection, the touch rod 365 first performs free fall motion. At this time, the damping adjustment component 368 provides the first damping for the touch rod 365. Afterwards, when the pressure sensor detects pressure, the damping adjustment component 368 provides the second damping for the touch rod 365 and limits its downward movement distance.

[0040] The second damping is greater than the first damping, and the second damping can ensure that the damping adjustment component 368 can clamp the touch stick.

[0041] At this time, the external air supply device is controlled to supply air, and the gas can drive the touch rod to move downward quickly, and the moving distance is limited so that the touch head will not cause damage to the screen of the mobile terminal to be detected. Specifically, the damping adjustment component 368 includes a damping loading micro-cylinder 3681, a reset spring 3683 and a limit ring 3684, wherein a plurality of circumferentially distributed damping loading micro-cylinders 3681 are arranged on the inner side of the outer ring 367, and a damping pad 3682 is fixed to the output end of the damping loading micro-cylinder 3681. The damping loading micro-cylinder 3681 is also set to slide along the axial direction of the outer ring 367. The bottom of the damping loading micro-cylinder 3681 is connected to the outer ring 367 by a reset spring 3683, and the inner bottom of the outer ring 367 is fixed with a limit ring 3684.

[0042] That is to say, by controlling the external gas supply device to supply gas, the gas can drive the touch rod to move downward quickly, and the damping loading micro-cylinder 3681 moves accordingly. At this time, the reset spring can provide it with a buffer, as well as subsequent reset. Under the limitation of the limit ring 3684, the touch head will not cause damage to the screen of the mobile terminal to be tested.

[0043] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
