[0041] The purpose of the material receiving system for FPC board sorting provided by the present utility model is to sort FPC boards with similar expansion coefficients together, and then select different parts according to different expansion coefficients of the FPC boards and assemble them with the FPC boards. For example, FPC boards with larger expansion coefficients are assembled with components with the same larger expansion coefficients. In this way, the subsequent assembly effect can be better, and the quality of the product can be better maintained.

[0042] The incoming FPC boards are in a stacked state, and then the stacked FPC boards are sorted. At the same time, there is separator paper between different layers of FPC boards to protect the FPC boards. When sorting, first, a conventional structure such as a suction cup or a manipulator sucks the top FPC board and transfers it to a vision inspection platform. This platform is made of transparent glass, and there is a camera below it to take pictures of the FPC board and compare several holes on the edge of the FPC board to determine the expansion coefficient of this individual FPC board. After the determination, the suction cup or the manipulator moves the FPC board upward and then translates it onto a certain outer support plate 5 or inner support plate 7, and then the suction cup or the manipulator comes back to move the separator paper and place it on this FPC board (which can isolate it from the next FPC board); then the suction cup and the manipulator move back to their original positions and suck the next FPC board. It should also be understood that what this application claims to protect is a material receiving system for receiving FPC boards and separator paper, while the suction cup, vision inspection platform, etc. are not the structures claimed to be protected in this application. They are introduced here only for auxiliary explanation, and even if they are not fully and completely described, it does not affect the scope of protection claimed in this application.

[0043] The structures for receiving FPC boards with different expansion coefficients are the inner support plate 7 and the outer support plate 5. For example, FPC boards with a larger expansion coefficient are placed on the outer support plate 5, and those with a smaller expansion coefficient are placed on the inner support plate 7. The inner support plate 7 and the outer support plate 5 are each driven to move by a first driving mechanism and a second driving mechanism, respectively, and at the same time, the outer support plate 5 and the inner support plate 7 do not affect each other. In this way, the purpose of saving space can be achieved, and the compactness of the equipment is better.

[0044] In this application, there are several receiving units, and the suction cup, etc. can send the FPC board and the separator paper to any outer support plate 5 and inner support plate 7. In this way, the FPC boards with different expansion coefficients can be more detailedly subdivided, that is, the classification of FPC boards can be made more accurate, which can play a more promoting role in subsequent assembly. At the same time, since each inner support plate 7 is located below the outer support plate 5, the compactness of the entire equipment can be further improved.

[0045] When the outer support plate 5 moves, only the first motor 11 drives the first lead screw 10 to rotate, and then the first lead screw 10 can drive the outer plate body 4 to move, and at the same time drive the outer support plate 5 to move; similarly, the second motor 15 and the second lead screw 14 can also drive the inner support plate 7 and the inner plate body 6 to move reciprocally, and the inner support plate 7 and the outer support plate 5 do not affect each other.

[0046] When the quantity of FPC boards reaches a certain amount or when the FPC boards are taken off one by one, workers can either manually sample or use other mechanical structures such as manipulators to automatically pick up materials; when picking up materials, the first relief opening 17 and the first material taking opening 16 enable the FPC boards on the outer support plate 5 to be more conveniently taken off; similarly, the second relief opening and the second material taking opening 18 enable the FPC boards on the inner support plate 7 to be more conveniently taken off.

[0047] Not only that, when receiving the FPC boards, the limiting part 23 can also play a role in limiting the periphery of the FPC boards to prevent them from running off, etc., and at the same time can also prevent the spacer paper from falling off. Since the sizes of different FPC boards are different, the position of the limiting part 23 needs to be adjusted; when adjusting, just rotate the limiting part 23 so that the locking rod 22 moves upward relative to the anti - detachment block 20, so that the anti - detachment block 20 can move downward a very small distance, and then can move along the length direction of the limiting groove 19; after moving to the appropriate position, rotate the limiting part 23 until the locking rod 22 touches the bottom of the limiting groove 19 and the top of the anti - detachment block 20 touches the inner wall of the limiting groove 19. At this time, the position and angle of the limiting part 23 are fixed, and the FPC boards can be limited; when limiting, it is preferably at a certain distance from the FPC boards to facilitate the normal placement of the FPC boards.

[0048] When the thickness of the FPC boards and the spacer paper is relatively large (i.e., there are many layers), at this time, the lower pressing plate 27 can also press down on the FPC boards to squeeze out some of the air in the middle and improve the position stability of a stack of FPC boards. The lower pressing plate 27 and the manipulator or suction cup used to grab the FPC boards are located on both sides of the horizontal frame 25, and the lower pressing frame 26 and the suction cup, etc. do not affect each other. When the suction cup, etc. place the FPC boards in place, the first motor 11 or the second motor 15 moves the FPC boards to the other side of the horizontal frame 25; then the third motor 29 and the third lead screw drive the horizontal movable frame 28 to move to the appropriate position, the fourth motor 32 and the fourth lead screw drive the transmission frame 33 to move downward, and the lower pressing plate 27 presses on the top spacer paper or FPC board (at this time, the lower pressing plate 27 is higher than the limiting part 23 or an avoidance hole is provided on the lower pressing plate 27, and the limiting part 23 can be inserted into the avoidance hole so that the lower pressing plate 27 can move downward normally); then the transmission frame 33 continues to move downward, and the bottom of the transmission frame 33 touches the top of the elastic member 36, that is, at this time, the transmission frame 33 presses the lower pressing plate 27 downward through the elastic member 36 and presses the FPC boards to the appropriate degree; since the elastic member 36 makes the acting force gradually increase, in this way, the air between different layers can be better discharged, and at the same time, it can also prevent excessive pressure on the FPC boards, playing a protective role for the FPC boards.

[0049] After the downward pressing is completed, the transmission frame 33 rises. When the transmission frame 33 touches the bottom of the anti-disengagement part 35, the lower pressing plate 27 can be raised through the anti-disengagement part 35 and the guide rod 34. The lower pressing frame 26 is movably sleeved on the horizontal movable frame 28. At the same time, the horizontal frame 25 is perpendicular to the projections of all the outer tracks 2 and the inner tracks 3 in the vertical direction. Therefore, the lower pressing plate 27 can act on all the outer supporting plates 5 and the inner supporting plates 7.

[0050] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way.
