[0065] The vacuum adsorption plate 113 of this embodiment has multiple spaced vacuum adsorption holes for introducing negative pressure gas to adsorb the display screen 10 and fix the display screen 10 on the vacuum adsorption plate 113. The multiple grooves on the top surface of the adapter plate 112 that connect the vacuum adsorption holes are used to connect a vacuum negative pressure device through a single vacuum pipeline, which facilitates the connection of the vacuum adsorption plate 113 to the negative pressure gas source and makes the structural arrangement of the panel carrier 110 more neat.

An elongated hole is provided at one end of the locking plate 102 that is in contact with the first upper sliding platform 122 or the second upper sliding platform 125. A locking screw 103 is provided on the side wall of both the first upper sliding platform 122 and the second upper sliding platform 125, passing through the elongated hole and threadedly connected to the first upper sliding platform 122 or the second upper sliding platform 125. The locking screw 103 has a pressing surface that presses against the locking plate 102.

[0073] In this embodiment, after the X-axis slide and Y-axis slide have adjusted the spatial orientation of the display screen 10, they are held in place. Locking plates 102 are fixedly connected to both the first sliding base 121 and the second sliding base 124. The locking plates 102 are fixedly connected to the side wall of the first sliding base 121 or the second sliding base 124 by screws. The locking plates 102 are securely connected to the first upper slide 122 or the second upper slide 125 by locking screws 103, thereby limiting changes in the position of the adjusted X-axis and Y-axis slides and improving the positioning reliability of the display screen 10.

[0074] In some alternative embodiments: see Figures 6 to 8 As shown in the figure, this application embodiment provides an automatic insertion device for display panel testing. The second adjustment mechanism 220 of the automatic insertion device includes a lower slide seat 222 slidably connected to a base 201 via a lower slide rail 221. The lower slide seat 222 reciprocates along the Y-axis direction on the lower slide rail 221. An upper slide seat 224 is slidably connected to the top of the lower slide seat 222 via an upper slide rail 223. The upper slide seat 224 reciprocates along the X-axis direction on the upper slide rail 223.

[0075] The lower slide 222 reciprocates along the Y-axis on the lower slide rail 221 to adjust the position of the test circuit board 20 in the Y-axis direction. The upper slide 224 reciprocates along the X-axis on the upper slide rail 223 to adjust the position of the test circuit board 20 in the X-axis direction. A rotary table 225 that rotates around the Z-axis is rotatably connected to the upper slide 224. A flip plate 226 that flips around the X-axis is rotatably connected to the top of the rotary table 225. The top of the flip plate 226 is provided with a height adjustment mechanism for connecting the mounting plate 202.

[0076] The rotary table 225 is rotatably connected to the upper slide 224, allowing the rotary table 225 to rotate around the Z-axis. The flip plate 226 is rotatably connected to the top of the rotary table 225, allowing the flip plate 226 to flip around the X-axis. A height adjustment mechanism is connected to the top of the flip plate 226, allowing the mounting plate 202 to move up and down along the Z-axis.

[0077] The second adjustment mechanism 220 of this application embodiment utilizes the lower slide 222, upper slide 224, rotary table 225, flip plate 226 and height adjustment mechanism to achieve linear movement in the X, Y and Z axis directions, as well as rotation around the Z axis and around the X axis, thereby adjusting the posture of the test circuit board 20 connected to the mounting plate 202 along the five axes, so that the test circuit board 20 can be connected to different types of display screens 10 with greater adjustment flexibility.

[0078] In some alternative embodiments: see Figures 6 to 8 As shown in the figure, this application embodiment provides an automatic insertion device for display panel testing. The drive mechanism 210 of the automatic insertion device includes a swing arm 211 with one end rotatably connected to the base 201, and guide pins 237 that are slidably connected to the swing arm 211 are fixedly connected to both ends of the sliding seat 222. A guide hole is provided on the swing arm 211 for the guide pin 237 to pass through. The length direction of the guide hole is parallel to the length direction of the swing arm 211, so that when the swing arm 211 pushes the sliding seat 222 to reciprocate along the Y-axis direction on the sliding rail 221, the guide pin 237 has room for movement.

[0079] A handle 212 is fixedly connected to the other end of the swing arm 211. An automatic telescopic mechanism 213, which drives the swing arm 211 to rotate on the base 201, is rotatably connected to the base 201. The automatic telescopic mechanism 213 is rotatably connected to the swing arm 211. The automatic telescopic mechanism 213 is preferably, but not limited to, an automatic extension and retraction mechanism such as a cylinder or an electric cylinder. When the automatic telescopic mechanism 213 extends, it drives the swing arm 211 to move on the base 201 in a direction close to the display positioning mechanism 100. When the automatic telescopic mechanism 213 retracts, it drives the swing arm 211 to move on the base 201 in a direction away from the display positioning mechanism 100.

[0080] The drive mechanism 210 of this embodiment is provided with a swing arm 211, one end of which is rotatably connected to the base 201. The swing arm 211 is slidably connected to the lower slide seat 222 via a guide pin 237. By driving the swing arm 211 to rotate around the base 201, the lower slide seat 222 can be driven to reciprocate along the Y-axis on the lower slide rail 221. The swing arm 211 can be connected to a handle 212 for manual drive or to an automatic telescopic mechanism 213 for drive, which improves the flexibility of the drive mechanism 210.

[0081] The base 201 includes a base plate and a side plate that are perpendicularly connected to each other. The side plate is located at one end of the base plate and is perpendicularly connected to each other to form an "L" shape. The side plate is fixedly connected to the panel carrier 110 of the display positioning mechanism 100 to avoid positional changes between the panel carrier 110 and the mounting plate 202 when adjusting the panel carrier 110 and the detection camera for center positioning, thereby reducing the difficulty of alignment adjustment between the display 10 and the test circuit board 20.

[0082] In some alternative embodiments: see Figures 6 to 8 As shown in the figure, this application embodiment provides an automatic insertion device for testing display panels. The lower slide 222 of the automatic insertion device is fixedly connected to a first lug 231. A first adjusting screw 232, which drives the upper slide 224 to reciprocate along the X-axis, is rotatably connected to the first lug 231. The first adjusting screw 232 is rotatably connected to the first lug 231, and the position of the upper slide 224 along the X-axis can be adjusted by adjusting the length of the first adjusting screw 232.

[0083] The rotary table 225 has multiple concentric arc holes 233. Bolts connecting to the upper slide 224 are installed within the arc holes 233 of the rotary table 225. A second lug 234 is fixedly connected to the upper slide 224. A second adjusting screw 235, which drives the rotary table 225 to reciprocate around the Z-axis, is located on the second lug 234. The second adjusting screw 235 is rotatably connected to the second lug 234, and the rotation angle of the rotary table 225 around the Z-axis can be adjusted by adjusting the length of the second adjusting screw 235.

[0084] Both ends of the tilting plate 226 are threadedly connected to a third adjusting screw 236, which drives the tilting plate 226 to rotate around the X-axis. The end of the third adjusting screw 236 abuts against the top surface of the rotary table 225. Two third adjusting screws 236 are provided and located on either side of the rotation axis around which the tilting plate 226 rotates. The rotation angle of the tilting plate 226 around the X-axis can be adjusted by adjusting the length of the third adjusting screw 236.

[0085] The height adjustment mechanism includes a lower slider 227 and an upper slider 228 that are connected by sliding force. A curved plate 229 is rotatably connected to the lower slider 227 to adjust the lifting and lowering movement of the upper slider 228. The lower slider 227 is equipped with a Z-axis micrometer knob 230 that drives the curved plate 229 to rotate. The Z-axis micrometer knob 230 is fixed to the lower slider 227. By manually rotating and adjusting the Z-axis micrometer knob 230, the Z-axis micrometer knob 230 drives the curved plate 229 to rotate up and down, thereby controlling the lifting and lowering movement of the upper slider 228.

[0086] The first adjusting screw 232, the second adjusting screw 235, the third adjusting screw 236, and the Z-axis micrometer knob 230 in this embodiment are used to make the mounting plate 202 move linearly in the Y-axis and Z-axis directions, and rotate around the Z-axis and X-axis directions, respectively, so as to precisely adjust the posture of the test circuit board 20 connected to the mounting plate 202, and thus precisely align and plug into the connector of the display screen 10.

[0087] In some alternative embodiments: see Figure 3 and Figure 4 As shown in the embodiment of this application, an automatic insertion device for testing display panels is provided. The pressing mechanism 130 of the automatic insertion device includes a fixed bracket 131 fixed on a panel carrier 110. A guide rod 132 is slidably connected to the fixed bracket 131, and a pressure plate 134 is connected to the guide rod 132. A lifting mechanism 133 is connected between the pressure plate 134 and the fixed bracket 131 to drive the pressure plate 134 to move towards or away from the panel carrier 110. The lifting mechanism 133 is preferably, but not limited to, a cylinder or an electric cylinder. When the lifting mechanism 133 extends, it drives the pressure plate 134 to press the PCB board of the display screen 10, thereby pressing the PCB board of the display screen 10 onto the panel carrier 110.

[0088] In this embodiment, the pressing mechanism 130 is used to press the PCB board on the display screen 10 onto the panel carrier 110 before the connector of the display screen 10 and the connector of the test circuit board 20 are mated together, in order to prevent the PCB board on the display screen 10 from shifting. The pressing mechanism 130 has a fixed bracket 131 mounted on the panel carrier 110. A pressure plate 134 is connected to the fixed bracket 131 via a guide rod 132. The pressure plate 134 moves towards or away from the panel carrier 110 under the driving action of the lifting mechanism 133 to achieve the pressing action and improve the positional alignment accuracy when the connectors are mated together.

[0089] Working principle

[0090] The automatic insertion device for display panel testing in this application includes a display screen positioning mechanism 100, which includes a base plate 101, a panel carrier 110 for placing and positioning a display screen 10 above the base plate 101, a first adjustment mechanism 120 for adjusting the spatial posture of the panel carrier 110 between the base plate 101 and the panel carrier 110, and a pressing mechanism 130 for pressing the display screen 10 on the top of the panel carrier 110; a connector insertion and removal mechanism 200, which includes a base 201, a mounting plate 202 for fixing a test circuit board 20 on the base 201, a second adjustment mechanism 220 for adjusting the posture between the mounting plates 202 slidably connected to the base 201, and a drive mechanism 210 for driving the second adjustment mechanism 220 and the mounting plate 202 to move in a direction close to or away from the display screen positioning mechanism 100.

[0091] Therefore, the automatic insertion device for display panel testing in this application utilizes the cooperation of the display positioning mechanism 100 and the connector insertion / removal mechanism 200 to achieve rapid alignment and automatic insertion / removal connection between the display screen 10 located on the display positioning mechanism 100 and the test circuit board 20 located on the connector insertion / removal mechanism 200. Specifically, the display positioning mechanism 100 uses the panel carrier 110 to position and support the display screen 10, and uses the first adjustment mechanism 120 to adjust the spatial orientation of the display screen 10 on the panel carrier 110. After adjusting the spatial orientation of the display screen 10, the connector of the display screen 10 can achieve precise docking with the connector of the test circuit board 20, and the display screen 10 can be centered directly below the testing camera, enabling centered testing by the testing camera.

[0092] The connector insertion / removal mechanism 200 includes a mounting plate 202 for fixing the test circuit board 20, and a second adjustment mechanism 220 at the bottom of the mounting plate 202 for adjusting the spatial orientation of the mounting plate 202 and the test circuit board 20. After the second adjustment mechanism 220 adjusts the spatial orientation of the test circuit board 20, the connector of the test circuit board 20 is precisely aligned with the connector of the display screen 10. The drive mechanism 210 moves the second adjustment mechanism 220 and the mounting plate 202 in a direction that approaches or moves away from the display screen positioning mechanism 100, thereby automatically inserting the connector of the test circuit board 20 mounted on the mounting plate 202 into the connector of the display screen 10, automatically completing the insertion action to light up the display screen 10, improving work efficiency and saving labor costs.
