Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-5 The utility model provides a technical solution: a temporary storage device for circuit board transportation, comprising:

[0038] The transplanting mechanism 1 is driven by a horizontal driving mechanism 8 and is arranged on a device stand 9; wherein the horizontal driving mechanism 8 is a linear motor;

[0039] A first material taking mechanism 3, which is connected to one side of the transplanting mechanism 1 through a first vertical driving mechanism 2;

[0040] A second material taking mechanism 5, which is connected to the other side of the transplanting mechanism 1 through a second vertical driving mechanism 4;

[0041] A plurality of material grabbing members 6, which are arranged on the first material picking mechanism 3 and the second material picking mechanism 5, and include a lifting rod 61 and a suction cup 62 at the bottom of the lifting rod 61. The lifting rod 61 is passed through the first material picking mechanism 3 and the second material picking mechanism 5 and a limit block 63 is provided at the end of the movable interval;

[0042] The lifting mechanism 10 has a top lifting drive provided with a transfer table 11 for temporarily storing the circuit board 100. The two sides of the lifting mechanism 10 are respectively connected to the conveying mechanism. In this embodiment, the conveying mechanism is a driving conveying structure in which a driving roller shaft cooperates with a conveyor belt.

[0043] The outer side of the connection end between the transplanting mechanism 1 and the horizontal driving mechanism 8 is connected to a drag chain 13 to improve the stability of the transplanting mechanism 1 when being driven to move.

[0044] The device stand 9 is provided with a shielding belt 12 above the horizontal driving mechanism 8, and the horizontal driving mechanism 8 is provided with a top dust-proof design and a shielding design to ensure its efficient operation.

[0045] Specific as Figure 3 , 4 As shown, the suction cup 62 is a telescopic folding suction cup, which includes a plurality of axially arranged and fixed conical units 621. This design can realize rotatable and direction-adjustable adsorption of the circuit board 100, and can adapt to the different horizontal positions of each grabbing member 6 on the material picking mechanism and the stable adsorption and grabbing requirements when the circuit board 100 is slightly deformed.

[0046] The bottom of the conical unit 621 on the upper layer is provided with a connecting port located in the center and an exhaust port 622 on the outside. The bottom of the conical unit 621 on the bottom is provided with a suction port, which can realize the rapid discharge of internal air when the suction cup 62 is squeezed and adsorbed, so as to realize the internal negative pressure and vacuum environment, and avoid the problem that the suction port and the circuit board 100 are not adsorbed quickly and stably due to the discharge of gas at the suction port when the common suction cup is squeezed and adsorbed. During the lifting activity, the exhaust port 622 is blocked due to the influence of the folding structure; and when the circuit board 100 is driven to shake and desorb, the internal pressure of the suction cup 62 can also be quickly restored to speed up the desorption process.

[0047] The lifting rod 61 is hollow and the top is connected to the negative pressure system in the transplanting mechanism 1, so that the internal pressure of the suction cup 62 can be quickly adjusted to achieve fast and efficient adsorption and desorption of the circuit board 100.

[0048] A pre-lifting drive mechanism 7 is provided on the material grabbing member 6 on one side of the second material taking mechanism 5, and the material grabbing member 6 is inserted into the pre-lifting drive mechanism 7. The pre-lifting drive mechanism 7 drives a lifting block provided below the linkage block on the side of the material grabbing member 6. This design allows the circuit board 100 to be taken from the transfer table 11 by first repeatedly lifting and lowering one side of the circuit board 100 through the pre-lifting drive mechanism 7, and then coordinating with the transfer table 11 to move downward, so as to achieve the removal of a single circuit board 100, and avoid the problem of it being taken out at the same time as the lower layer circuit board 100 due to adsorption and stacking. Among them, the two vertical drive mechanisms and the pre-lifting drive mechanism 7 are one or more of a cylinder, a hydraulic cylinder or a motor.

[0049] The working principle of a temporary storage device for circuit board transportation in this embodiment includes: when in use, Figure 2 , the horizontal driving mechanism 8 drives the transplanting mechanism 1, so that it drives the first material picking mechanism 3 to move above the circuit board 100 on the conveying mechanism on one side, and the first vertical driving mechanism 2 drives the first material picking mechanism 3 to move downward, and the material grabbing member 6 performs docking and adsorption of the circuit board through the suction cup 62, and at the same time, moves upward along the first material picking mechanism 3 for buffering. An elastic member can be arranged between the two to improve the buffering performance of the structure. The first material picking mechanism 3 abuts against the limit block 63 to complete the downward movement and adsorption operation; the horizontal driving mechanism 8 and the first vertical driving mechanism 2 drive the driving device to reset, and the first vertical driving mechanism 2 drives the first material picking mechanism 3 to move downward and stop instantly, so as to realize the shaking off of the circuit board 100 and place the circuit board 100 on the transfer table 11; Figure 5 The second vertical drive mechanism 4 drives the second material picking mechanism 5 to move downward, so that it can achieve docking and adsorption of the grabbing piece 6 and the circuit board 100 in the same way as the first material picking mechanism 3; the pre-lifting drive mechanism 7 drives the corresponding grabbing piece 6 to move up and down, so that the stacked circuit boards 100 are separated, and the transfer table 11 is driven to move downward to realize the removal of a single circuit board 100. The driving method adopts a cylinder, a hydraulic cylinder or a motor. After that, the transplanting mechanism 1 moves to the conveying mechanism on the other side to load, subsequently convey and process the circuit board 100.

[0050] In summary, due to the adoption of the above technical solution, the circuit board transfer temporary storage device of this embodiment has the following beneficial effects compared with the prior art:

[0051] 1. This device can realize structural buffering when driving the grabbing part to dock and adsorb the circuit board through the material taking mechanism and the grabbing part, so as to avoid damage to the circuit board.

[0052] 2. The transfer table with lifting drive is equipped with pre-lifting drive mechanism, which can realize the efficient removal of single circuit boards, thereby realizing efficient material loading and unloading and transfer.

[0053] 3. The use of telescopic foldable suction cups can realize the rotatable and direction-adjustable adsorption of circuit boards, and can adapt to the different horizontal positions of the grabbing parts on the material-collecting mechanism and the stable adsorption and grabbing requirements when the circuit boards are slightly deformed.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
