continuing to refer to fig. 3, firstly, feeding is performed, a worker puts the bottom diaphragms in the feeding frame 210, and the material lifting module 212 drives the lifting plate 213 to lift the bottom diaphragms in the feeding frame 210 one by one until the bottom diaphragms reach the feeding frame infrared sensor 211; the first negative pressure suction cup 250 is linked with the feeding X-axis slide rail pair 241, the feeding Y-axis slide rail pair 242 and the feeding Z-axis cylinder 243 to transfer the bottom membrane in the feeding frame 210 to the feeding conveying belt 220;
continuing to refer to fig. 5, then, performing bottom film separation, wherein the single-sided film 231 provides traction force through the tape transport roller 230 and is wound on the surface of the feeding transport belt 220 for circulation, the sticky side of the single-sided film 231 faces upwards, the single-sided film can be stuck with the bottom film for recovery in the circulation process, and the FPC light bar can be peeled off and waits for the first transfer mechanism 300 to clamp in the process that the bottom film is recovered along the single-sided film 231 at the foremost end of the transport belt;
then taking out the FPC light bar, when the FPC light bar is peeled off from the bottom membrane to the front end of the material conveying belt 220, the FPC light bar is identified by the material infrared sensor 330, the material infrared sensor 330 sends a signal to a control computer so as to control the rubber belt conveying roller 230 to pause and work, then the first CCD sensor 340 acquires the coordinate of the connecting part 1 of the FPC light bar, the clamping manipulator 320 transfers the three-axis sliding rail pair 310 in a linkage manner to acquire the coordinate according to the first CCD sensor 340, the connecting part 1 of the FPC light bar is clamped, and the FPC light bar is displaced to a set adsorption coordinate;
continuing to refer to fig. 6, then positioning the FPC light bar, after the FPC light bar is clamped by the clamping manipulator 320, the material placing table 401 is slid to a position below a set adsorption coordinate by driving of the Y-axis screw slide rail pair 407, then the clamping manipulator 320 is released, and the FPC light bar is transferred onto the material placing table 401, then the material placing table 401 is reset to an initial position, the left and right limiting cylinders 404 and the front and rear limiting cylinders 405 respectively drive the left and right limiting baffles 402 and the front and rear limiting baffles 403 to simultaneously approach to the center of the material placing table 401, and push the FPC light bar until the FPC light bar is pushed to a set position of the center;
and finally, transferring the FPC light bar out of the machine, after the FPC light bar is positioned in the positioning mechanism 400, sucking the FPC light bar by the multi-axis manipulator 510 and the second negative pressure sucker 520, scanning the contour coordinates of the FPC light bar by the second CCD sensor 530, sending the contour coordinates to the control computer, comparing the contour coordinates with the set coordinates by the control computer, controlling the multi-axis manipulator 510 to adjust the position of the FPC light bar, and transferring the FPC light bar out of the FPC light bar assembly machine to be assembled after the position of the FPC light bar is adjusted to the set coordinates.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
