[0051] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in combination with specific embodiments.

[0052] In order to monitor whether the metal conductive block 330 of the test port on the test fixture is seriously worn, as shown in Figure 1 The present application provides an OLED module test fixture for detecting an OLED module 200, which comprises a jig bottom plate 100, a plurality of first terminals 300, a plate body 500, a shell 600, a plurality of top heads 800, and two third blocks 1600. Specifically, as shown in Figure 3 The plurality of first terminals 300 are fixedly installed on the upper surface of the jig bottom plate 100 by means of the conductive pins arranged at the bottom thereof. As shown in Figure 4 The upper surface of each of the two first terminals 300 is provided with a first groove 320, as shown in Figure 5 and Figure 6As shown, the plate body 500 is arranged inside the first groove body 320 and is slidingly mounted with the inner wall thereof, so the plate body 500 can move up and down along the first groove body 320, and since the first groove body 320 is arranged in the first terminal 300, the plate body 500 can move up and down along the first terminal 300. Figure 4 As shown, the inner wall of the first groove body 320 is symmetrically provided with a plurality of metal conductive blocks 330, and in order to facilitate the plate body 500 to move up and down along the first groove body 320, the outer surface of the opposite two sides of the plate body 500 is provided with a plurality of openings 510, and the metal conductive blocks 330 are arranged inside the openings 510, so as not to interfere with the up and down movement of the plate body 500. Because, as shown, Figure 8 As shown, the upper surface of the plate body 500 is provided with a through groove 520, and the shell 600 is arranged inside the through groove 520 and is slidingly mounted with the inner wall thereof, so the shell 600 can move up and down along the inner wall of the through groove 520, and since the through groove 520 is arranged in the first terminal 300, the shell 600 can move up and down along the first terminal 300. Figure 7 As shown, a plurality of top heads 800 are arranged inside the plurality of openings 510, and as shown, Figure 10 As shown, one end of the top head 800 close to the shell 600 penetrates the inner wall of the through groove 520 and is slidingly mounted with the plate body 500, so when one end of the top head 800 abuts against the outer surface of the metal conductive block 330, it can move close to the shell 600 along the central axis direction thereof, and since, as shown, Figure 9 and Figure 10 As shown, two third blocks 1600 are arranged at the two ends of the shell 600, and when the plate body 500 moves up and down, the positions of the plate body 500 can be limited by the two third blocks 1600 so that it cannot move downward, and the two third blocks 1600 are coupled with the plurality of top heads 800, and when the plurality of top heads 800 move close to the shell 600 along the central axis direction of the top head 800, the two third blocks 1600 can be driven to move away from each other, thereby releasing the position limitation of the plate body 500 so that it can move downward. Through the device, when the end surface of the plurality of top heads 800 abuts against the highest point of the outer surface of the metal conductive block 330, the plurality of top heads 800 will move close to the shell 600 along the central axis direction thereof, at this time, the two third blocks 1600 move away from each other so that the plate body 500 can continue to move downward, and when the outer surface of the metal conductive block 330 is worn to a certain value, because the moving distance of the plurality of top heads 800 is not enough, the distance of the two third blocks 1600 moving away from each other is small, so that the position limitation of the plate body 500 cannot be released, and the plate body 500 cannot continue to move downward. Through the arrangement, the operator can be reminded in time that the wear of the metal conductive block 330 is serious and the first terminal 300 needs to be replaced, avoiding unstable electrical connection during detection of the OLED module 200, and ensuring the accuracy of the detection result.

[0053] In order to realize the detection of the test fixture on the OLED module 200, as shown, Figure 2As shown, the lower surface of the OLED module 200 is provided with two second terminals 400, the lower surface of the two second terminals 400 is provided with a fourth groove, the top wall of the fourth groove is fixedly connected with a polar plate 420, the outer surfaces of the opposite sides of the polar plate 420 are provided with a plurality of conductive sheets, during detection, the operator manually inserts the polar plate 420 into the inside of the first groove 320, so that the conductive sheet abuts against the metal conductive block 330, thereby realizing electrical connection, and because the conductive pin and the circuit printed on the jig bottom plate 100 are in electrical connection, the plurality of metal conductive blocks 330 are in electrical connection with the corresponding conductive pins, and the metal conductive blocks 330 are powered by the power supply connected through the circuit printed on the jig bottom plate 100, after the conductive sheet abuts against the metal conductive block 330, the OLED module 200 displays the information of normal power-on, thereby determining whether the OLED module 200 is functional, and completing the function test of the OLED module 200. When the polar plate 420 is inserted into the inside of the first groove 320, it will contact the upper surfaces of the plate body 500 and the shell 600, thereby driving the plate body 500 and the shell 600 to move downward to the groove bottom of the first groove 320.

[0054] It should be noted that, in order to avoid the polar plate 420 being inserted into the first groove 320 of the first terminal 300 in the wrong direction, as shown in Figure 2 and Figure 4 shown, the outer surfaces of the first terminal 300 close to the two ends are respectively provided with notches 310, the inner walls of the fourth groove close to the two ends are provided with protrusions 410 matched with the notches 310, through the cooperation of the notches 310 and the protrusions 410, the polar plate 420 cannot be inserted into the first groove 320 in the wrong way.

[0055] In order to enable the plurality of jacks 800 to move along the central axis direction of the jack 800 to move close to the shell 600, thereby driving the two third blocks 1600 to move away from each other, as shown in Figure 12 shown, the inside of the shell 600 is provided with a cavity 610, the inner walls of the cavity 610 close to the two ends are symmetrically slidably installed with two piston plates 1500, the outer surfaces of the two piston plates 1500 away from each other are fixedly connected with second rod bodies 1000, through the movement of the two piston plates 1500 away from each other, the second rod bodies 1000 respectively drive the two third blocks 1600 to move away from each other. In order to enable the two piston plates 1500 to move away from each other, as shown in Figure 13 shown, the outer surfaces of the opposite sides of the shell 600 are symmetrically provided with a plurality of through holes, the inner walls of the plurality of through holes are fixedly connected with a sheet 620, the sheet 620 has a certain flexibility and can be elastically deformed when stressed, and can restore to the original state when the stress is removed, because the inside of the cavity 610 between the two piston plates 1500 is filled with hydraulic oil, and as Figure 10As shown, the other end of the top head 800 can abut against the outer surface of the sheet 620, and the one end of the top head 800 abuts against the metal conductive block 330, so that when the top head 800 moves close to the shell 600, the top head 800 will squeeze the sheet 620, so that the hydraulic oil inside the cavity 610 is squeezed, thereby pushing the two piston plates 1500 to move away from each other, and making the two piston plates 1500 drive the third blocks 1600 to move away from each other through the second rod bodies 1000.

[0056] In order to make the two piston plates 1500 correctly move away from each other, the two piston plates 1500 completely seal the two ends of the cavity 610, and as shown, Figure 13 As shown, since the two piston plates 1500 are respectively formed with inner cavities with the inner walls of the two ends of the shell 600, in order to make the inner cavities communicate with air, the upper surface of the second rod body 1000 is provided with an air channel 1010, the air channel 1010 is in communication with the inner cavities, and the air channel 1010 is in communication with the external environment, so that the air pressure inside the inner cavities is balanced.

[0057] In order to make the two third blocks 1600 limit the position of the plate body 500, as shown, Figure 9 and Figure 15As shown, the other end of the second rod body 1000 penetrates the end face of the shell 600, the other end of the second rod body 1000 is fixedly connected with the third block 1600, the second rod body 1000 and the third block 1600 are vertically arranged in a T-shaped structure, and the first groove body 320 is provided with a second groove body 340 close to the inner wall of the two ends, the first terminal 300 is provided with two third groove bodies 350 symmetrically on the upper surface close to the two ends, the second groove body 340 and the third groove body 350 are connected in communication, the width of the third groove body 350 is greater than that of the second groove body 340, the third block 1600 and the third groove body 350 are matched, and the second rod body 1000 and the second groove body 340 are matched. When the two third blocks 1600 move away from each other, the third block 1600 will move above the third groove body 350, and when the plate body 500 continues to move downward, the third block 1600 will continue to slide downward along the inner wall of the third groove body 350. When the two third blocks 1600 do not move away from each other or the distance of moving away from each other is not enough, the two third blocks 1600 cannot correctly enter the inside of the third groove body 350, thereby limiting the plate body 500 from continuing to move downward. It should be noted that because the metal conductive block 330 needs to have a certain wear range in actual use, a fixed gap is provided between the third groove body 350 and the third block 1600, and the size of the gap is the wear value of the metal conductive block 330. Within the wear value range, the third block 1600 can slide on the inner wall of the third groove body 350. In order for the plate body 500 to move downward to the bottom of the first groove body 320, the second groove body 340, the third groove body 350 and the first groove body 320 are arranged with the same depth.

[0058] It should be noted that when the OLED module 200 test fixture is used for a long time, the operator needs to regularly detect whether the metal conductive block 330 is in electrical communication with the circuit on the fixture bottom plate 100 through the surface probe of the multimeter. In order to avoid the operator from mistakenly touching the plate body 500 with the small probe when using, the upper surface of the shell 600 is higher than the upper surface of the plate body 500 in the initial state (i.e., when the pole plate 420 is not inserted into the first groove body 320). At this time, the sheet 620 installed on the side surface of the shell 600 is a distance higher than the top head 800, as shown in the figure. Figure 10 As shown, the end of the top head 800 close to the shell 600 abuts against the side surface of the shell 600, so that the top head 800 cannot extrude the sheet 620, thereby preventing the two third blocks 1600 from moving away from each other, so that the plate body 500 cannot continue to move downward, and the small probe cannot break the metal conductive block 330.

[0059] Because the upper surface of the shell 600 is higher than the upper surface of the plate body 500, when the polar plate 420 is ready to be inserted into the first groove body 320, it will first contact the upper surface of the shell 600, and by the polar plate 420 pressing the shell 600 downward, the shell 600 moves downward along the through groove 520 until the upper surface of the shell 600 is flush with the upper surface of the plate body 500, at this time, the end of the top head 800 close to the shell 600 will be in contact with the surface of the sheet 620, in order to make the shell 600 move downward to the upper surface flush with the upper surface of the plate body 500, as shown in Figure 11 , the plate body 500 is provided with a first vertical groove close to the two ends, and the other end of the second rod body 1000 penetrates the first vertical groove and is slidably installed on the inner wall of the first vertical groove, and the cooperation of the first vertical groove and the second rod body 1000 limits the distance of the shell 600 moving downward along the through groove 520.

[0060] In order to further ensure that the shell 600 can only move downward when the upper surface is flush with the upper surface of the plate body 500, as shown in Figure 9 , the upper surface of the plate body 500 close to the two ends is symmetrically provided with two sink grooves 530, as shown in Figure 11 , the inner wall of the two sink grooves 530 is slidably installed with a first block 1300, the outer surface of the side of the first block 1300 away from each other is fixedly connected with a first rod body 900, one end of the first rod body 900 penetrates the outer surface of the plate body 500 and is slidably installed thereon, the outer surface of the other side of the first block 1300 is fixedly connected with a spring 1200, the other end of the spring 1200 is fixedly connected with the inner wall of the sink groove 530 away from one end of the first rod body 900, and the elastic force of the spring 1200 makes the first block 1300 drive the first rod body 900 to extend out of the inside of the sink groove 530 and be located outside the end surface of the plate body 500, and because the width of the first rod body 900 is greater than that of the second groove body 340, when the upper surface of the shell 600 is not moved downward to be flush with the upper surface of the plate body 500, the first rod body 900 will be blocked at the top of the second groove body 340, so that the plate body 500 cannot continue to move downward, and through this arrangement, the top head 800 is prevented from being in contact with the metal conductive block 330 when it does not move to the position of the sheet 620, because the top head 800 is blocked by the shell 600 at this time, so it cannot move, which ensures that the top head 800 will not damage the surface of the metal conductive block 330 and cause it to deform and collapse.

[0061] In order to make the first rod body 900 retract into the sink groove 530 when the shell 600 moves downward along the through groove 520 until the upper surface is flush with the upper surface of the plate body 500, and ensure that the plate body 500 can normally move downward later, as shown in Figure 12As shown, the lower surface of the shell 600 is symmetrically fixedly connected with two fourth blocks 1800, the lower surface of each of the two fourth blocks 1800 is provided with a fourth inclined surface 1810, the upper surface of the first block 1300 is provided with a first inclined surface 1310 matched with the fourth inclined surface 1810, by moving the shell 600 downward, the fourth inclined surface 1810 of the lower surface of the fourth block 1800 abuts against the first inclined surface 1310 of the upper surface of the first block 1300, thereby driving the two first blocks 1300 to move close to each other, and further driving the two first blocks 1300 to retract the first rod 900 into the sink groove 530.

[0062] As shown, the lower surface of the shell 600 is symmetrically fixedly connected with two fourth blocks 1800, the lower surface of each of the two fourth blocks 1800 is provided with a fourth inclined surface 1810, the upper surface of the first block 1300 is provided with a first inclined surface 1310 matched with the fourth inclined surface 1810, by moving the shell 600 downward, the fourth inclined surface 1810 of the lower surface of the fourth block 1800 abuts against the first inclined surface 1310 of the upper surface of the first block 1300, thereby driving the two first blocks 1300 to move close to each other, and further driving the two first blocks 1300 to retract the first rod 900 into the sink groove 530. Figure 12 and Figure 16 As shown, the inner wall of the two sink grooves 530 near the two ends is slidably provided with an insertion plate 1100, one side of the outer surface of the insertion plate 1100 is flush with the end surface of the shell 600, the other side of the outer surface of the insertion plate 1100 is flush with the inner wall of the sink groove 530, the top end of the insertion plate 1100 is higher than the upper surface of the shell 600, when the polar plate 420 is ready to be inserted into the first groove 320, it will first contact the top end of the insertion plate 1100, thereby driving the insertion plate 1100 to move downward. Since the upper surface of the first inclined surface 1310 near the bottom is fixedly connected with a baffle 1700, the bottom end of the fourth block 1800 abuts against the top end of the baffle 1700, when the bottom end of the fourth block 1800 is still at the position of the top end of the baffle 1700, at this time, the shell 600 cannot be moved downward to the position where the upper surface thereof is flush with the upper surface of the plate body 500, in order for the insertion plate 1100 to move downward to drive the fourth block 1800 to move away from the baffle 1700, the upper surface of each of the two sink grooves 530 is fixedly connected with a second block 1400, the upper surface of the second block 1400 is provided with a second inclined surface 1410, the lower surface of the insertion plate 1100 is provided with a third inclined surface 1110 matched with the second inclined surface 1410, the insertion plate 1100 moves downward to drive the two first rods 900 to move close to each other by a distance through the third inclined surface 1110 and the second inclined surface 1410, the distance makes the bottom of the fourth block 1800 move away from the top of the baffle 1700, at this time, the fourth inclined surface 1810 falls into the upper surface of the baffle 1700, thereby enabling the first rod 900 to continue to retract into the sink groove 530 when the shell 600 moves downward, if the polar plate 420 is inserted obliquely towards one end, it will cause one of the two insertion plates 1100 to be unable to be pressed by the polar plate 420, thereby avoiding the first rod 900 from further retracting into the sink groove 530, and preventing the plate body 500 from continuing to move downward, thereby avoiding the polar plate 420 from breaking the metal conductive block 330, in order for the insertion plate 1100 to move downward correctly, as shown in Figure 12As shown, the outer surface of the plug-in plate 1100 is provided with a second vertical groove, and the second rod body 1000 is slidably installed in the second vertical groove.

[0063] In order to make the plate body 500 be above the metal conductive block 330 when the test fixture is not used, as shown in Figure 3 and Figure 14 As shown, the plate body 500 is symmetrically fixedly installed with two slide columns 700 near the lower surfaces of the two ends, the bottom ends of the two slide columns 700 are sleeved with a tension spring 710 penetrating the lower surface of the fixture bottom plate 100, one end of the tension spring 710 is fixedly connected with the lower surface of the fixture bottom plate 100, and the other end of the tension spring 710 is fixedly connected with the bottom end of the slide column 700. Through the elastic force of the tension spring 710, the slide column 700 drives the plate body 500 to be above the metal conductive block 330, so as to protect the metal conductive block 330 from being accidentally touched and damaged, and meanwhile, through the tension spring 710, the upper surface of the plate body 500 can always abut against the bottom end of the polar plate 420 when being pressed by the polar plate 420.

[0064] In the embodiment, as shown in Figure 10 In order to limit the top head 800 from sliding out of the plate body 500, the diameter of the top head 800 near one end of the shell 600 is greater than that of the other end.
