The probe 12722 is not required to be pressed all the time manually in the test process, and the operation is simple and easy. By providing the projection 1281 on the stopper 128, the stopper 128 is made convenient to rotate. The anti-slip grooves can play a role in preventing slipping.

With continued reference to fig. 5, the flip 1271 further includes a second decompression position, wherein the first decompression position is located between the second decompression position and the compression position, and an acute angle is formed between the first decompression position and the compression position.

The carrier assembly 12 further includes a magnetic attraction 129 disposed on a top surface of the carrier plate 121, the flip 1271 being coupled to the magnetic attraction 129 when the flip 1271 is in the second decompressed position. The first decompression position and the compression joint position are acute angles, and the first torsion spring 130 only drives the flip 1271 to be located at the first decompression position, so that damage caused by collision between the flip 1271 and the bearing plate 121 after the flip 1271 is overturned due to overlarge elastic force can be avoided. At this time, if the carrying component 12 is carried, the flip 1271 is easily rocked due to external influence, and with the above structure, the flip 1271 is manually rotated to move from the first decompression position to the second decompression position, and in the process of moving from the first decompression position to the second decompression position, the flip 1271 is separated from the first torsion spring 130, and the first torsion spring 130 no longer generates an acting force on the flip 1271. And when the flip 1271 is moved to the second decompressed position, the magnetic attraction 129 is connected, so that the flip 1271 can be prevented from shaking.

The touch screen 1001 is placed in the cavity 1211, the touch PCB1002 is placed in the PCB positioning groove 1212, the touch PCB1002 is absorbed through the vacuum absorption hole 1216, the touch FPC1003 is placed in the FPC positioning groove 1213, the output end of the touch FPC1003 is inserted on the input end of the FPC jack 122, the output end of the FPC jack 122 is connected with the input end of the FPC docking module 123 through the adapter plate 124, the output end of the FPC docking module 123 is connected with the contact pin of the input end of the plug-in module 113 through the contact, the output end of the plug-in module 113 is connected with an external test instrument, and the backlight 112 irradiates the touch screen 1001 to perform OTP test, TP test and ET test. After the detection is completed, the crimping module on the testing instrument is withdrawn, and the detection carrier flows back.

When the silver paste test is required to be performed on the touch PCB1002, the flip 1271 is manually rotated to the press-connection position, the second torsion spring drives the limiting piece 128 to be positioned at the lock position, the clamping strip 12711 is positioned in the clamping groove, and the limiting piece 128 fixes the flip 1271 at the press-connection position; when the silver paste test is completed, the limiting piece 128 is rotated to the unlocking position, the clamping groove is separated from the clamping strip 12711, at this time, the first torsion spring 130 drives the flip cover 1271 to be located at the first decompression position, and the probe 12722 is separated from the touch screen 1001. Manually rotating the flap 1271 to the second decompressed position and connecting the flap 1271 to the magnetic attraction 129.

Thus, the working process of the detection logistics jig of the preferred embodiment is completed.

When the detection logistics jig is used for testing a touch panel, a touch screen is placed in a cavity, a touch PCB is placed in a PCB positioning groove, a touch FPC is placed in the FPC positioning groove, the output end of the touch FPC is inserted into the input end of an FPC jack, and then the output end of an insert module is connected with an external testing instrument, so that the detection logistics jig can be used for testing; the touch panel of different specifications, its touch screen, touch PCB and touch FPC's size can change, touch FPC's output and plug-in components module's input can stagger, when the touch panel of different specifications is tested, only need change corresponding carrier assembly can, make the size of die cavity and touch screen assorted, PCB constant head tank's size and touch PCB's size assorted, FPC's size and touch FPC's size assorted, simultaneously, FPC's output can be connected with FPC's input of jack, FPC's output can be connected with FPC's input electricity of module, FPC's output can be connected with plug-in components module's input electricity, then when touch FPC's output staggers with plug-in components module's input, also can be connected touch FPC with plug-in components module electricity through FPC jack and butt joint module. Aiming at touch panels with different specifications, only different bearing components need to be replaced, so that the cost can be saved, and the universality module is increased.

In summary, although the present invention has been described with reference to the preferred embodiments, the scope of the invention is not limited thereto, and any person skilled in the art who is skilled in the art should make equivalent substitutions or modifications according to the technical scheme of the present invention within the scope of the present invention.
