In order to facilitate the technical solution disclosed in the present invention to be fully understood by those skilled in the art, the following detailed description is made in conjunction with the specific embodiments, and fig. 1 shows a schematic perspective view of a testing tool suitable for an electronic panel of the present invention, which is mainly composed of a base 1, a loading fixture 2, an electronic panel assembly 3, an electrical conduction transfer assembly 4, a testing unit 5, and a suction cup module 6. The loading fixture 2 is detachably fixed on the base 1 by screws, and a receiving groove 21 (shown in fig. 9) extends downwards from the upper plane of the loading fixture. The electronic panel 3 assembly includes an electronic panel 31 and a conductive flat cable 32. The electrical flat cable 32 is connected to the electronic panel 31, electrically connected thereto, and integrally sunk in the receiving recess 21. The electrically conductive transfer assembly 4 is used in cooperation with the electrically conductive flat cable 32, and is inserted into and fixed to the base 1, and is disposed right in front of the loading fixture 2. The test unit 5 is adapted to the electrically conducting relay member 4, electrically conducted, and disposed at the right side of the base 1 in alignment. When the electronic panel assembly 3 is placed in position relative to the loading fixture 2, a complete electrical testing loop is formed among the electronic panel 31, the electrical flat cable 32, the electrical conduction relay assembly 4 and the testing unit 5.

It should be emphasized that fig. 2 shows a schematic perspective view of the testing tool for electronic panels according to the present invention (with the electronic panel and a part of the base hidden), and a suction cup module 6 is further added. The suction cup module 6 includes a vacuum suction nozzle 61 (shown in fig. 14) and a vacuum generator (not shown in the drawings). The vacuum generator is communicated with the suction nozzle 61 to provide suction negative pressure for the suction nozzle. The number of the vacuum suction nozzles 61 is 4, and the vacuum suction nozzles are respectively arranged at four corners of the accommodation recess 21 to realize suction fixing of the electronic panel 31. By adopting the technical scheme, in the actual operation process, the worker can conveniently and quickly finish the disassembling and assembling operation of the electronic panel 31 only by controlling the on/off of the vacuum suction nozzle 61, so that on one hand, the time consumed by the disassembling and assembling process of the electronic panel 31 is greatly reduced, and the detection efficiency is effectively improved; on the other hand, the labor intensity of workers is effectively reduced, and two or even three stations can be considered by a single person at the same time, so that the cost of human resources is reduced manyfold.

It should be noted that the number of the vacuum nozzles 61 may also be adaptively selected according to the area, thickness, material and other factors of the pre-loaded electronic panel 31, so as to ensure reliable and stable adsorption of the electronic panel 31.

As is known, the suction-function end of the vacuum nozzle 61 is made of rubber and has a certain axial compressibility (as shown in FIG. 14). Based on this, and in view of avoiding the vacuum suction nozzle 61 from colliding with the electronic panel 31 during the application process and ensuring that the electronic panel 31 has a good flatness after being sucked, a preferred scheme is recommended here, which is specifically as follows: a nozzle placing hole 211 (shown in fig. 9) extends downward from the bottom wall of the receiving recess 21. The vacuum nozzles 61 are built in and fixed in the nozzle-placing holes 211 in a one-to-one correspondence with the tops thereof being set a distance a (as shown in fig. 2) beyond the bottom walls of the accommodating recesses 21. The value a needs to be set according to the stress and material of the single vacuum suction nozzle 61 during actual operation, and is generally not more than 1 mm.

The electrically conductive relay member 4 disposed between the electrically conductive flat cable 32 and the testing unit 5 can adopt various design structures to achieve the current conducting function, however, a preferred scheme is recommended here, specifically as follows: as shown in fig. 2 to 7, the electrically conductive relay member 4 is mainly composed of a support base 41, a test substrate 42, pogo pins 43, a PCB 44, and an electrical connector 45. Thereafter, the supporting base 41 is detachably and fixedly connected to the base 1, and is formed by sequentially connecting a top plate 411, a supporting column 412 and a bottom plate 413 from top to bottom (as shown in fig. 10). The PCB 44 is pressed between the base 413 and the base 1. The pogo pin 43 is composed of an upper conductive terminal 431, a middle fixing section 432 and a lower conductive terminal 433 in sequence from top to bottom (as shown in fig. 13). Both the upper conduction terminal 431 and the lower conduction terminal 433 can perform axial telescopic movement relative to the middle fixed section 432. The middle fixing section 432 is inserted into and fixed on the top plate 411 to fix the position of the pogo pin 43. The test substrate 42 is disposed right above the top plate 411, and has a first through hole 421 for the upper conductive terminal 431 to pass through, so as to be in electrical contact with the electrical cable 32 by elastic abutting contact (as shown in fig. 12). A second through hole 4131 is formed in the bottom plate 413 for the lower conductive terminal 433 to pass through, and electrically connected to the PCB 44 by elastically abutting against the bottom plate (as shown in fig. 11). The electrical connector 45 is inserted and fixed on the sidewall of the base 1, electrically connected with the PCB 44, and directly corresponds to the testing unit 5. Through adopting above-mentioned technical scheme to set up, its electric conduction that compares in traditional project organization passes through transfer subassembly 4, and this electric conduction passes through transfer subassembly 4 has comparatively succinct project organization, does benefit to the manufacturing implementation, and later stage maintainability is better, and can ensure stability, the reliability that the electric current switched on effectively.

Moreover, as a further optimization of the structure of the above-mentioned electric conduction transit assembly 4, a guide post 46, a cylindrical spring 47 and a limit screw 48 may be further added according to actual requirements. The limit screw 48 passes through the test substrate 42, and the lower end portion thereof is screwed and fixed to the top plate 411, and correspondingly, a screw through hole 423 through which the limit screw 48 freely passes is formed in the test substrate 42. The guide posts 46 are fixed to the top plate 411, and correspondingly, guide holes 422 adapted to the guide posts 46 are opened in the test board 42. The cylindrical spring 47 is elastically urged between the test substrate 42 and the top plate 411 (as shown in fig. 2 and 3). In this way, the test substrate 42 has a certain floating property with respect to the supporting base 41, that is, the test substrate 42 can perform adaptive translational motion along its own axial direction, thereby effectively ensuring reliable contact between the flat cable 32 and each pogo pin 43 and ensuring stability and reliability of current conduction.

Moreover, in order to further ensure the reliable contact between the flat cable 32 and the retractable probe 43 and prevent the occurrence of poor electrical contact, the testing tool for the electronic panel may further include a limiting device 7, which is mounted on the loading fixture 2 in a matching manner. The stopper 7 includes a pressing plate 71, a hinge shaft (not shown), and a magnet 72. The hinge shaft is arranged and fixed on the loading jig 2. The pressing plate 71 is fixed to the loading jig 2 by the hinge shaft, and can be freely turned over with respect to the flat cable 32. The magnet 72 is mounted and fixed to the non-hinged end of the platen 71 (as shown in fig. 8). When the electronic panel 31 assembly is placed in position relative to the loading fixture 2 and the suction of the suction cup module 6 is completed, the pressing plate 71 is turned over in time, and the magnetic force of the magnet 72 is assisted to stably press the electronic panel against the flat cable 32.

Here, the magnet 72 may be mounted on the loading jig 2 and directly face the non-hinged end of the pressing plate 71 according to actual conditions. Of course, when the required pressing force is large, the magnet 72 (not shown) may be added to the pressing plate 71 and the loading jig 2.

Finally, it should be noted that a proximity sensor 73 may be further added to the limiting device 7. The proximity sensor 73 is installed and fixed on the loading jig 2 and is disposed opposite to the hinge shaft to sense and detect whether the pressing plate 71 is turned over in place in real time (as shown in fig. 8). In the actual use process of the test fixture for the electronic panel, the proximity sensor 73 can detect whether the pressing plate 71 is turned over in place relative to the loading fixture 2 in real time, and then can determine whether the flat cable 32 is reliably pressed.
