[0002] Flexible printed circuit board (FPC) is a commonly used electronic component. It is thin, light, flexible and bendable. It is widely used in mobile phones, tablet computers, laptops and other products. When making liquid crystal display screens, flexible printed circuit boards are combined with liquid crystal panels. In order to improve the efficiency of mass production, automatic feeders are usually used to transport FPCs to the assembly line. However, due to the small size and thinness of flexible printed circuit boards, a large number of flexible printed circuit boards will be stored in a single tray, and the position of the flexible printed circuit board relative to the tray will be offset and changed due to the transportation process of the tray, resulting in the inability of traditional automatic feeders to accurately pick up the flexible printed circuit board. As a result, the automatic feeder is often prone to errors due to failure to pick up the flexible printed circuit board, which seriously affects the feeding efficiency of the flexible printed circuit board.

[0023] See also Figure 1The embodiment of the present application provides a material rapid identification and transfer device, including a loading platform 1, a control computer, a tray changing robot 3, and a material picking part 2. Among them, a backlight system 11 is provided on the upper surface of the loading platform 1, and a transparent tray 4 containing materials is arranged on the loading platform 1; the material picking part 2 includes a material picking robot 21 and an image receiver 22 arranged on the lower side of the material picking robot 21; the tray changing robot 3 is arranged on one side of the material picking part 2, and the tray changing robot 3 is used to take away the empty tray 4 on the loading platform 1 and transport the tray 4 containing materials to the loading platform 1; the control computer is electrically connected to the material picking part 2 and the tray changing robot 3, and the control computer receives the image received by the image receiver 22, and analyzes the material distribution and position coordinates according to the image, and controls the material picking part 2 and the tray changing robot 3 to work.

[0024] The material rapid identification and transfer device provided in the present embodiment is provided with a backlight system 11 on the upper surface of the loading platform 1, so that when the transparent tray 4 containing materials is located on the loading platform 1, the materials on the tray 4 will block the light emitted by the backlight system 11 from irradiating into the image receiver 22. Therefore, the image receiver 22 can determine the specific position of the material according to the shadow shape position of the received image, and send the received image information to the control computer, and use the control computer to control the material picking part 2 to accurately pick up the material. When the received image indicates that there is no material on the tray 4, the control computer controls the tray changing robot 3 to replace the tray 4, that is, to take away the empty tray 4 and then move the tray 4 containing materials to the loading platform 1.

[0025] In one embodiment, a groove is provided on the upper surface of the loading platform 1, and the size of the groove is consistent with the size of the tray 4, and the backlight system 11 is provided at the bottom of the groove. By providing the groove on the upper surface of the loading platform 1, the tray 4 is positioned by using the groove, so that the tray 4 can be accurately located at the preset position of the loading platform 1, so that the subsequent material taking part 2 can take the material on the tray 4.

[0026] Since the material (sheet FPC) in the tray 4 is prone to tilt and rotate at a certain angle when the tray 4 moves (including the material transportation process and the process of the tray changing robot 3 transporting the tray 4 to the loading platform 1), it is easy to cause the material picking part 2 to be unable to load the material in the correct posture. For this reason, in one embodiment, the material picking robot 21 includes an XYZ three-axis motion mechanism 211, a rotation adjustment part 212, and a material picking part 213; the rotation adjustment part 212 is arranged on the XYZ three-axis motion mechanism 211, and the material picking part 213 is arranged on the rotation axis of the rotation adjustment part 212. By setting up the rotation adjustment part 212, when the image receiver 22 feeds back the material image to the control computer, the control computer can know whether the material has been tilted and rotated and its specific rotation angle, and then control the rotation adjustment part 212 to rotate in the opposite direction by the same angle after the material picking part 213 (a vacuum suction cup is provided at the bottom of the material picking part 213, and the material is picked up by vacuum suction) picks up the material, so as to ensure that the material can be loaded in the correct posture.

[0027] In one embodiment, the material picking portion 213 is provided with an elastic telescopic structure. In order to protect the material and prevent the material from being damaged by the material picking portion 213 during the loading process, an elastic telescopic structure is provided in the material picking portion 213. Specifically, the material picking portion 213 may include a first picking block and a second picking block, the second picking block is slidably disposed on the first picking block, and an elastic member is disposed between the two, and a vacuum suction cup structure is disposed on the second picking block. When the vacuum suction cup structure on the second picking block picks up the material, the second picking block can slide by overcoming the elastic force of the elastic member, thereby preventing the material from being damaged by the material picking portion 213 during the loading process.

[0028] In one embodiment, four vacuum suction cups are arranged at the bottom of the tray changing robot 3, and the four vacuum suction cups respectively correspond to the four corners of the tray 4. By arranging four vacuum suction cups at the bottom of the tray changing robot 3, the stability of the tray changing robot 3 during the tray changing action is ensured.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
