[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] This embodiment provides an automatic loading and unloading device for flexible printed circuit boards (PCBs). This device automates the loading and unloading of PCBs without requiring manual operation, thus improving efficiency, reducing labor costs, and preventing omissions in steps, which facilitates subsequent processing of the PCBs.

[0030] Combination Figures 1 to 4As shown, the automatic flexible circuit board loading and unloading equipment of this embodiment includes a front-end conveyor line 10, a rear-end conveyor line 20, a sizing section 30, a limiting section 40, a loading platform 50, and a transfer section 60. The front-end conveyor line 10 and the rear-end conveyor line 20 realize the effective transport of the flexible circuit board, while the sizing section 30 can sizing the flexible circuit board located on the rear-end conveyor line 20 for subsequent loading and unloading operations. The limiting section 40 limits the flexible circuit board at the end of the rear-end conveyor line 20. The transfer section 60 moves the sizing flexible circuit board into the loading platform 50 to complete the loading and unloading operation of the flexible circuit board.

[0031] In this embodiment, the automatic flexible circuit board feeding and receiving equipment also includes a base 70. The front conveyor line 10, the rear conveyor line 20, the straightening part 30, the limiting part 40, and the transfer part 60 are all installed on the base 70. The loading platform 50 is located above the front conveyor line 10 and is connected to the base 70 through a side plate 80. There are two loading platforms 50. In this embodiment, there are two loading platforms 50 and they are set above the front conveyor line 10. While not affecting the flexible circuit board feeding, the structure is simplified and the overall integration of the equipment is higher.

[0032] Combination Figure 1 and Figure 2 As shown, the front-end conveyor line 10 in this embodiment is a belt conveyor line. The front-end conveyor line 10 includes two sets of first conveyor lines 11 arranged opposite to each other. An adjustment part 90 is provided between the two sets of first conveyor lines 11. The adjustment part 90 includes an adjustment motor 91, an adjustment gear 92, an adjustment rack 93, and a movable seat 94. The adjustment gear 92 is mounted on the shaft end of the adjustment motor 91. There are two adjustment racks 93, which mesh with the adjustment gear 92. When the adjustment gear 92 rotates, the two adjustment racks 93 move towards each other or in opposite directions. The first conveyor lines 11 are connected by the movable seat 94. The seat 94 is connected to the corresponding adjusting rack 93. In this embodiment, the existence of the adjusting part 90 can adjust the distance between the two first conveying lines 11 so that the front end conveying line 10 can adapt to flexible circuit boards of different specifications and improve the versatility of the equipment. The specific adjustment process is as follows: the adjusting motor 91 drives the adjusting gear 92, the adjusting gear 92 meshes with the adjusting rack 93, so that the adjusting rack 93 moves in opposite directions or in reverse, thereby driving the first conveying line 11 to move through the movable seat 94, so as to realize the adjustment of the distance between the two sets of first conveying lines 11.

[0033] Combination Figure 1 and Figure 3As shown, the rear conveyor line 20 includes two sets of fixed and oppositely arranged roller conveyor lines 21. The sizing section 30 is located at the rear conveyor line 20. The sizing section 30 includes a sizing motor 31, a sizing gear 32, a sizing rack 33, a movable block 34, and a sizing plate 35. The sizing gear 32 is installed on the shaft end of the sizing motor 31. There are two sizing racks 33 that mesh with the sizing gear 32. When the sizing gear 32 rotates, the two sizing racks 33 move towards each other or in opposite directions. The sizing plate 35 is connected to the corresponding sizing gear through the movable block 34. When the flexible circuit board arrives at the rear conveyor line 20, it needs to be shaped by the sizing unit 30 for subsequent transfer. The sizing motor 31 of the sizing unit 30 drives the sizing gear 32, and the two sizing racks 33 mesh with the sizing gear 32. Therefore, when the sizing gear 32 rotates, the two sizing racks 33 move in opposite directions. The sizing racks 33 drive the sizing plates 35 to move through the movable block 34. The two sets of sizing plates 35 size the flexible circuit board from both sides.

[0034] In this embodiment, the straightening plate 35 is an L-shaped plate. The straightening plate 35 is located in the gap between the rollers of the roller conveyor line 21. The straightening plate 35 will not affect the roller conveyor line 21. Its L-shaped structure can effectively straighten the flexible circuit board while avoiding interference with the roller conveyor line 21.

[0035] Combination Figure 1 and Figure 4 As shown, in this embodiment, the limiting part 40 is located at the end of the rear conveyor line 20. The limiting part 40 includes a limiting drive module 41, a limiting cylinder 42, and a limiting plate 43. The limiting drive module 41 drives the limiting cylinder 42, and the limiting cylinder 42 lifts the limiting plate 43 to limit the flexible circuit board. The transfer part 60 includes a transfer module 61 and a transfer suction cup 62. The transfer module 61 drives the transfer suction cup 62. When the transfer suction cup 62 adsorbs the flexible circuit board, it transfers the flexible circuit board to a predetermined position. After the flexible circuit board is aligned, it continues to move along the rear conveyor line 20. Under conveying, when the flexible circuit board reaches the position of the limiting part 40, the limiting drive module 41 and the limiting cylinder 42 of the limiting part 40 extend the limiting plate 43 to limit the flexible circuit board so that the flexible circuit board can be loaded and unloaded in the subsequent process. After the flexible circuit board is limited, the transfer module 61 of the transfer part 60 drives the transfer suction cup 62 to the position of the flexible circuit board. The transfer suction cup 62 adsorbs the flexible circuit board and then the transfer module 61 transfers the transfer suction cup 62 to the loading table 50 to complete the unloading operation of the flexible circuit board.

[0036] In this embodiment, the limiting cylinder 42 is connected to the limiting drive module 41 via a mounting base, and the limiting plate 43 is installed at the end of the piston rod of the limiting cylinder 42. When it is necessary to feed the flexible circuit board, the limiting cylinder 42 drives the limiting plate 43 to move downward, so that the limiting plate 43 no longer limits the flexible circuit board, so that the flexible circuit board can be fed.

[0037] Furthermore, the transfer module 61 in this embodiment is a three-axis module, all of which are lead screw driven modules, driving the transfer suction cup 62 from multiple directions so that the transfer suction cup 62 can adsorb the flexible circuit board.

[0038] In actual use, the flexible circuit board automatic loading and unloading equipment of this embodiment uses a front-end conveyor line 10 to transport flexible circuit boards. The front-end conveyor line 10 is suitable for flexible circuit boards of different specifications. The flexible circuit boards enter the rear-end conveyor line 20 through the front-end conveyor line 10. The straightening unit 30 straightens the flexible circuit boards located on the rear-end conveyor line 20 to facilitate subsequent loading and unloading operations. After the flexible circuit boards are straightened, the limiting unit 40 limits the flexible circuit boards, and the transfer unit 60 transfers the flexible circuit boards to the loading platform 50 to complete the loading and unloading operation of the flexible circuit boards.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
