[0020] As Figure 1 and Figure 2 shown, the present application discloses a child camera display backlight board AOI detection device 100 for realizing the automatic detection of the backlight board. The detection device 100 includes a working platform 10, on which a feeding mechanism 20, a driving mechanism 30 and a detection mechanism 40 are arranged. The feeding mechanism 20 and the detection mechanism 40 are both arranged on the side of the driving mechanism 30. The feeding mechanism 20 is used to move the backlight board to the driving mechanism 30, and then the driving mechanism 30 drives the backlight board to a preset position, and the detection mechanism 40 detects the backlight board and performs a discharging process on the detected backlight board.

[0021] Combined with Figure 2 Referring to Figure 3 and Figure 4 , the feeding mechanism 20 includes a transmission component 22 and a feeding grasping component 21. The transmission component 22 is used to drive the backlight board to a preset working station, and the feeding grasping component 21 is used to grasp the backlight board at the preset working station to a preset position. Specifically, the feeding grasping component 21 includes a robotic arm 211 and a suction cup gripper 212. The robotic arm 211 can drive the suction cup gripper 212 to move, and the suction cup gripper 212 grasps the backlight board on the transmission component 22.

[0022] In the prior art, the suction cup gripper generally includes a fixed center and a plurality of grasping arms. Each grasping arm exists independently. One end of the grasping arm is fixedly matched with the fixed center by screws. Each grasping arm is relatively independent, and the disassembly and installation are carried out independently. In the case of having a plurality of grasping arms, it is necessary to fix them multiple times, the operation is complex and angle fixing parts are required, increasing the cost.

[0023] The suction cup gripper 212 disclosed in the present application has a simple structure and is convenient for disassembly and installation.

[0024] As Figure 4 and Figure 5As shown, the suction cup jaw 212 includes a support 2121, a cover plate 2122, a first clamping arm 2123, and a second clamping arm 2124. The robotic arm 211 is connected to the cover plate 2122 and drives the suction cup jaw 212 through the cover plate 2122. A first clamping arm groove 21211 and a second clamping arm groove 21213 are provided on the support 2121. The first clamping arm groove 21211 and the second clamping arm groove 21213 are cross-distributed. The first clamping arm 2123 is disposed in the first clamping arm groove 21211, and the second clamping arm 2124 is disposed in the second clamping arm groove 21213. The cover plate 2122 is connected to the support 2121 to fix the first clamping arm 2123 in the first clamping arm groove 21211 and the second clamping arm 2124 in the second clamping arm groove 21213. Both ends of the first clamping arm 2123 extend out of the first clamping arm groove 21211 respectively, and both ends of the second clamping arm 2124 extend out of the second clamping arm groove 21213 respectively. Vacuum suction heads 125 are respectively connected to both ends of the first clamping arm 2123 and both ends of the second clamping arm 2124. The suction cup jaw 212 adsorbs the backlight panel through the vacuum suction heads 2125. In this application, the first clamping arm 2123 is placed in the first clamping arm groove 21211, and the second clamping arm 2124 is placed in the second clamping arm groove 21213. Then, when the cover plate 2122 is fixedly connected to the support 2121, the first clamping arm 2123 and the second clamping arm 2124 can be fixed and positioned on the support 2121 without using fixing devices such as screws to separately fix the clamping arms, and the operation is simple.

[0025] In this application, both ends of the first clamping arm 2123 and both ends of the second clamping arm 2124 extend out of the support 2121. Furthermore, the first clamping arm 2123 and the second clamping arm 2124 respectively fix the vacuum suction heads 2125 at both ends. The suction cup jaw 212 can grab the backlight panel through the four vacuum suction heads 2125. Fixing the first clamping arm 2123 and the second clamping arm 2124 simultaneously can achieve the effect of fixing four existing clamping arms.

[0026] The bottom surface of the first clamping arm groove 21211 is provided with a clamping arm recess 21212. A clamping arm protrusion 21231 is provided on the first clamping arm 2123. When the first clamping arm 2123 is placed in the first clamping arm groove 21211, the clamping arm protrusion 21231 is arranged in the clamping arm recess 21212. When the second clamping arm 2124 is placed in the second clamping arm groove 21213, the second clamping arm 2124 presses against the top surface of the clamping arm protrusion 21231; the upper surface of the second clamping arm 2124 and the upper surface of the first clamping arm 2123 are located on the same horizontal plane. Specifically, the clamping arm protrusion 21231 is formed by bending the first clamping arm 2123 downward. When the clamping arm protrusion 21231 is placed in the clamping arm recess 21212, it can not only position the first clamping arm 2123, but also enable the second clamping arm 2124 to be cross-distributed with the first clamping arm 2123, playing a role in avoiding interference. Moreover, it can also make the first clamping arm 2123 and the second clamping arm 2124 on the same horizontal plane, facilitating the installation of a vacuum adsorption device on the first clamping arm 2123 and the second clamping arm 2124 without the need for separate horizontal calibration on the horizontal plane.

[0027] A positioning shaft 21232 is provided on the first clamping arm 2123, and a pin shaft hole 21241 is provided on the second clamping arm 2124. When the first clamping arm 2123 is placed in the first clamping arm groove 21211 and the second clamping arm 2124 is placed in the second clamping arm groove 21213, the positioning shaft 21232 passes through the pin shaft hole 21241 to position the first clamping arm 2123 and the second clamping arm 2124. Specifically, when the clamping arm protrusion 21231 of the first clamping arm 2123 extends into the clamping arm recess 21212, the first clamping arm 2123 can be positioned with the support 2121, preventing the first clamping arm 2123 from sliding relative to the first clamping arm groove 21211. If on this basis the positioning shaft 21232 passes through the pin shaft hole 21241, at this time the first clamping arm 2123 can also position the second clamping arm 2124, preventing the second clamping arm 2124 from sliding relative to the second clamping arm groove 21213.

[0028] Further, at least one first positioning hole 21233 is provided on the first clamping arm 2123, at least one second positioning hole 21242 is provided on the second clamping arm 2124, a first positioning pin (not shown in the figure) corresponding to the first positioning hole 21233 and a second positioning pin (not shown in the figure) corresponding to the second positioning hole 21242 are provided on the cover plate 2122. When the cover plate 2122 is connected to the support 2121, the first positioning pin extends into the first positioning hole 21233 and the second positioning pin extends into the second positioning hole 21242. In this application, the cover plate 2122 and the support 2121 can be fixed by screws or snap connection. When the cover plate 2122 is fixedly connected to the support 2121, the first positioning pin extends into the first positioning hole 21233 and the second positioning pin extends into the second positioning hole 21242, thereby further positioning the first clamping arm 2123 and the second clamping arm 2124 and preventing the first clamping arm 2123 and the second clamping arm 2124 from shaking relative to the support 2121.

[0029] Further, the suction cup gripper 212 further includes a holding spring 21221. One end of the holding spring 21221 abuts against a positioning point on the second clamping arm 2124, and the other end of the holding spring 21221 abuts against the cover plate 2122. The cover plate 2122 presses the second clamping arm 2124 through the holding spring 21221. The positioning point on the second clamping arm 2124 is located at the intersection position of the second clamping arm 2124 and the first clamping arm 2123. In this application, the top end of the positioning shaft 21232 extends into the holding spring 21221 to position the holding spring 21221 and prevent the holding spring 21221 from sliding. When the cover plate 2122 is fixed to the support 2121, the cover plate 2122 abuts against the second clamping arm 2124 through the holding spring 21221, and the first clamping arm 2123 and the second clamping arm 2124 are abutted against the support 2121.

[0030] When sucking the backlight panel through the suction cup gripper 212, the robotic arm 211 needs to drive the suction cup gripper 212 to move downward. When the vacuum suction head 2125 abuts against the backlight panel, the holding spring 21221 can also play a certain buffering role. The vacuum suction head 2125 drives the first clamping arm 2123 and the second clamping arm 2124 to move upward or have a tendency to move upward. At this time, the holding spring 21221 can be used for buffering.

[0031] In this application, the loading mechanism 20 and the detection mechanism 40 are both arranged on the side of the driving mechanism 30. The loading and grasping component 21 is used to grasp the backlight panel from the transmission component 22 and move it to the driving mechanism 30. The driving mechanism 30 drives the backlight panel to move, and the detection mechanism 40 is used to perform optical detection on the backlight panel that has moved to a preset position. During operation, the robotic arm 211 grasps the backlight panel from a preset position of the transmission component 22 through the suction cup gripper 212, and then the robotic arm 211 moves the backlight panel to the driving mechanism 30 through the suction cup gripper 212. The robotic arm 211 can adopt an existing five-axis robotic arm, and no specific limitation is imposed on it in this application.

[0032] Please continue to refer to Figure 6 Furthermore, the transmission component 22 includes a first transmission bracket 221, a second transmission bracket 222, and a transmission motor 223. Among them, the first transmission bracket 221 is fixed to the working platform 10. The first end of the first transmission bracket 221 is close to the driving mechanism 30. A first roller 2211 is provided at the first end of the first transmission bracket 221, and a second roller 2212 is provided at the second end of the first transmission bracket 221. The first roller 2211 and the second roller 2212 are in transmission cooperation through a first transmission belt 2213. The transmission motor 223 is used to drive the first roller 2211 to rotate; the first end of the second transmission bracket 222 is connected to the second end of the first transmission bracket 221. A third roller 2221 is provided at the first end of the second transmission bracket 222, and a fourth roller 2222 is provided at the second end of the second transmission bracket 222. The third roller 2221 and the fourth roller 2222 are in transmission cooperation through a second transmission belt 2223; the third roller 2221 and the second roller 2212 are in transmission cooperation through a third transmission belt 224; a stopper 228 is provided at the first end of the first transmission bracket 221. The stopper 228 is used to stop the backlight panel at a preset station, and the loading and grasping component 21 grasps the backlight panel from the preset station to move it to the driving mechanism 30.

[0033] In the present application, by setting the first transmission bracket 221 and the second transmission bracket 222, the distance of the entire bracket can be increased, and the first transmission bracket 221 is provided with a first transmission belt 2213, and the second transmission bracket 222 is provided with a second transmission belt 2223, and the first transmission bracket 221 and the second transmission bracket 222 can also be transmitted and coordinated through the third transmission belt 224, and then when the transmission motor 223 drives the first roller 2211 to rotate, the backlight panel can be driven to move through the first transmission belt 2213, the second transmission belt 2223 and the third transmission belt 224. The three transmission belts are used for relay transmission to avoid the problem of loose transmission belts and poor transmission accuracy when using one transmission belt. When the transmission belt is long, it is easy to cause errors in transmission due to insufficient tension or accuracy problems. By setting three transmission belts for relay transmission, this problem can be solved to a large extent.

[0034] By providing the stopper 228 , when the backlight panel is transferred to the preset workstation, the stopper 228 prevents the backlight panel from being further transferred. At this time, the robot arm 211 can grab the backlight panel through the suction cup clamp 212 .

[0035] In the present application, two adjusting cylinders 225 are disposed on opposite sides of the first transmission bracket 221, and the two adjusting cylinders 225 are respectively located on both sides of the preset station, and top blocks 2251 are fixed to the output ends of the two adjusting cylinders 225, and the two adjusting cylinders 225 can adjust the position of the backlight panel through the top blocks 2251. The movement direction of the adjusting cylinder 225 is perpendicular to the transmission direction of the transmission component 22 to the backlight panel.

[0036] The transmission assembly 22 also includes a guide structure, which includes a first guide plate 2261 and a second guide plate 2262. The first guide plate 2261 and the second guide plate 2262 are both installed on the first transmission bracket 221 through a fixed rod 2263. The first guide plate 2261 and the second guide plate 2262 can slide along the fixed rod 2263; the extension direction of the fixed rod 2263 is perpendicular to the transmission direction of the transmission assembly 22; the distance between the first guide plate 2261 and the second guide plate 2262 away from the stopper 228 is greater than the distance between the first guide plate 2261 and the second guide plate 2262 close to the stopper 228. By setting the first guide plate 2261 and the second guide plate 2262, the backlight panel being transmitted can be prevented from deviating from the original transmission position to a certain extent. In the present application, the preset station is at the guide end of the guide structure, that is, after the backlight panel is separated from the guide structure, it can touch the stopper 228, and the position can also be adjusted by the adjustment cylinder 225.

[0037] An ion blower 227 is further provided on the transmission component 22. The ion blower 227 is disposed above the first conveyor belt 2213 to blow air on the backlight panel on the first conveyor belt 2213.

[0039] The detection mechanism 40 includes a first detection component 41, a second detection component 42, a film laminating component 43, and a blanking component 44. The first detection component 41, the second detection component 42, the film laminating component 43, and the blanking component 44 are evenly distributed on the circumference of the turntable 32. The turntable 32 drives the fixture component 33 to sequentially pass through the first detection component 41, the second detection component 42, the film laminating component 43, and the blanking component 44. The first detection component 41 is used to detect the brightness of the backlight panel, and the second detection component 42 is used to detect scratches and film bubbles on the backlight panel.
