Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a PCB board temporary storage and stacking machine. Background Art

[0002] PCBs, also known as printed circuit boards, are important electronic components used in a wide variety of electronic devices. PCB stacking machines are used to stack multiple PCBs to a predetermined height and number of layers, temporarily storing them for subsequent processing.

[0003] Chinese patent publication number CN218433785U discloses a compact PCB stacking machine. The device's operating principle for stacking PCBs is as follows: the support cylinder extends, and the fixed mechanism's push cylinder pushes the bottom PCB, causing it to fall from the support plate onto the support cylinder's pallet. The moving mechanism's push cylinder pushes the other side of the PCB off the support plate and onto a belt. The support cylinder then retracts, allowing the PCB closest to the fixed mechanism to fall onto the belt.

[0004] The disadvantage of the above-mentioned existing technical solution is that when the push cylinder pushes the PCB board onto the belt, this action causes all the PCB boards stacked above to vibrate, which easily causes their positions to shift, reducing the overall stability of the stacked PCB boards, thereby limiting the number of PCB boards that can be stacked. At the same time, frequent vibrations can easily cause scratches on the surfaces of adjacent PCB boards, affecting the processing effect of the PCB boards. Utility Model Content

[0005] The purpose of the utility model is to provide a PCB board temporary storage and stacking machine to solve the technical problem in the prior art that when a PCB board is pushed down onto a belt by a sheet-pushing cylinder, this action causes all the PCB boards stacked above to vibrate, thereby easily causing their positions to shift and reducing the overall stability of the stacked PCB boards.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solutions:

[0007] A PCB board temporary storage and stacking machine includes a lifting assembly for pushing PCB boards up, a stacking mechanism for storing PCB boards, a feeding assembly for feeding PCB boards into the stacking mechanism, and a feeding assembly for feeding PCB boards out of the stacking mechanism. The lifting assembly and the feeding assembly are both arranged on a double-belt conveyor device. The stacking mechanism includes a transverse movement assembly arranged on one side of the double-belt conveyor device. A moving frame is provided on the transverse movement assembly. A storage frame and a driving assembly for driving the storage frame to rise and fall are slidably fitted inside the moving frame. Multiple groups of storage cavities are provided inside the storage frame. Multiple groups of slots are provided on both sides of each group of storage cavities. A strap for supporting PCB boards is slidably fitted inside the slots. The feeding assembly is provided on one side of the transverse movement assembly.

[0008] As a further solution of the present invention: the drive components are provided with two groups, and are respectively arranged on both sides of the moving frame. Each group of the drive components includes at least two groups of rotating shafts rotatably connected to the inner wall of the moving frame. The two groups of the rotating shafts are cooperated with transmission belts fixedly connected to the storage frame. A motor is fixedly connected to the moving frame, and the output end of the motor is coaxially fixedly connected to the rotating shaft.

[0009] As a further solution of the present invention: the lifting assembly includes a first electric telescopic rod fixedly arranged on the double-belt conveyor device, the output end of the first electric telescopic rod is fixedly connected to a support plate, and the support plate is rotatably connected to multiple groups of support wheels for supporting PCB boards.

[0010] As a further solution of the present invention: the feeding assembly includes a second electric telescopic rod fixedly arranged on one side of the double-belt conveyor device, and the telescopic end of the second electric telescopic rod is fixedly connected to a first L-shaped push plate for pushing the PCB board to move.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 3 As shown, a PCB board temporary storage and stacking machine includes a lifting component for pushing the PCB board up, a stacking mechanism 7 for storing the PCB board, a feeding component for feeding the PCB board into the stacking mechanism 7, and a feeding component for feeding the PCB board out of the stacking mechanism 7.

[0023] The lifting assembly includes a first electric telescopic rod 2 fixedly arranged on the double-belt conveyor device 1, and the output end of the first electric telescopic rod 2 is fixedly connected to a support plate 3. The first electric telescopic rod 2 can drive the support plate 3 to move upward, and the support plate 3 is rotatably connected to multiple groups of support wheels 4 for supporting PCB boards.

[0024] The feeding assembly includes a second electric telescopic rod 5 fixedly arranged on one side of the dual-belt conveyor device 1. The telescopic end of the second electric telescopic rod 5 is fixedly connected to a first L-shaped push plate 6 for pushing the PCB board to move. The second electric telescopic rod 5 extends to drive the first L-shaped push plate 6 to move, and the PCB board on the support wheel 4 is pushed toward the stacking mechanism 7 through the first L-shaped push plate 6.

[0025] The stacking mechanism 7 includes an electric guide rail 701 arranged on one side of the dual-belt conveyor device 1. The extension direction of the electric guide rail 701 is parallel to the extension direction of the dual-belt conveyor device 1. A movable frame 702 is provided on the electric guide rail 701. A storage frame 703 and a driving component for driving the storage frame 703 to rise and fall are slidably fitted inside the movable frame 702. A plurality of storage cavities 709 for storing PCB boards are provided inside the storage frame 703. A plurality of slots 705 are provided on both sides of each storage cavity 709. A strap 704 for supporting the PCB board is slidably fitted inside the slot 705. The staff can place the strap 704 inside the corresponding slot 705 as needed to control the spacing between adjacent straps 704.

[0026] Two sets of drive assemblies are provided, one on each side of the movable frame 702. Each set of drive assemblies includes at least two sets of rotating shafts 706 rotatably connected to the inner wall of the movable frame 702. The two sets of rotating shafts 706 are equipped with transmission belts 707 fixedly connected to the storage frame 703. A motor 708 is fixedly connected to the movable frame 702, and the output end of the motor 708 is coaxially fixedly connected to the rotating shaft 706. The motor 708 drives the connected rotating shaft 706 to rotate, which in turn drives the transmission belt 707 to move. The transmission belt 707 drives the storage frame 703 to move, thereby achieving the effect of raising and lowering the storage frame 703.

[0027] The delivery assembly includes a support assembly 8 mounted on one side of the motorized guide rail 701. A third motorized telescopic rod 9 is fixedly connected to the support assembly 8. A second L-shaped push plate 10, which is used to push the PCBs, is fixedly connected to the telescopic end of the third motorized telescopic rod 9. Extending the third motorized telescopic rod 9 moves the second L-shaped push plate 10, which pushes the PCBs in the corresponding position until they are pushed away from the storage frame 703. The third motorized telescopic rod 9 then retracts, returning the second L-shaped push plate 10 to its original position.

[0028] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be described in conjunction with specific application scenarios:

[0029] When the PCB board on the dual-belt conveyor device 1 is transported to just above the support plate 3, the first electric telescopic rod 2 extends to drive the support plate 3 to move upward, and the support plate 3 drives the multiple sets of support wheels 4 to move upward, and the support wheels 4 push the PCB board away from the conveyor belt. Then the second electric telescopic rod 5 extends to drive the first L-shaped push plate 6 to move, and the PCB board on the support wheel 4 is pushed into the storage cavity 709 by the first L-shaped push plate 6. The PCB board will slide onto the corresponding strap 704. Then the first electric telescopic rod 2 and the second electric telescopic rod 5 are both retracted, driving the support wheel 4 and the first L-shaped push plate 6 to reset.

[0030] The motor 708 drives the connected rotating shaft 706 to rotate, and the rotating shaft 706 drives the transmission belt 707 to move, and the transmission belt 707 drives the storage frame 703 to move, thereby achieving the lifting effect of the storage frame 703. When the slat 704 receives the PCB board and the storage cavity 709 where it is located has storage space, the storage frame 703 can be driven to move, thereby driving the empty slat 704 to align with the first L-shaped push plate 6, so as to facilitate the reception of the next group of PCB boards; when the storage cavity 709 where the slat 704 is located is full, the electric guide rail 701 drives the moving frame 702 to move, so that another group of empty storage cavities 709 are aligned with the first L-shaped push plate 6, and then the position of the storage frame 703 is adjusted by the motor 708, so that the empty slat 704 at the bottom layer of the storage cavity 709 is aligned with the first L-shaped push plate 6, so as to facilitate the storage of more PCB boards;

[0031] When it is necessary to output the PCB board from the storage cavity 709, the position of the movable frame 702 can be adjusted first to align the storage cavity 709 to be output with the second L-shaped push plate 10, and the position of the storage frame 703 can be adjusted by the motor 708, so that the PCB board at the highest position in the storage cavity 709 is aligned with the second L-shaped push plate 10, and the third electric telescopic rod 9 extends to drive the second L-shaped push plate 10 to move, and the second L-shaped push plate 10 pushes the PCB board at the corresponding position to move until the PCB board is pushed away from the storage frame 703. At the same time, the first electric telescopic rod 2 extends to drive the supporting wheel 4 to align with the second L-shaped push plate 10, thereby catching the PCB board sent by the second L-shaped push plate 10, and then the first electric telescopic rod 2 retracts to drive the supporting wheel 4 to move downward, thereby placing the PCB board on the double-belt conveyor device 1, thereby realizing the output of the PCB board;

[0032] When the PCBs leave the storage cavity 709, the third electric telescopic rod 9 contracts, driving the second L-shaped push plate 10 to reset, and the motor 708 adjusts the position of the storage frame 703, so that the next group of PCBs are aligned with the second L-shaped push plate 10. The above operation is repeated. When all the PCBs in the storage cavities 709 of this group are output, the electric guide rail 701 drives the moving frame 702 to move, so that another group of storage cavities 709 is aligned with the second L-shaped push plate 10, thereby facilitating the output of the PCBs in the storage cavities 709 of the next group.

[0033] During use, the staff can place the straps 704 inside the corresponding slots 705 as needed to adjust the spacing between adjacent straps 704 to adapt to different work scenarios. When there are no electronic components soldered on the PCB board, the spacing between adjacent straps 704 can be adjusted according to the thickness of the PCB board. When the object to be stored is a PCB board with electronic components soldered on it, the spacing between adjacent straps 704 can be adjusted according to the size of the reference PCB board and the electronic components, thereby expanding the scope of use.

[0034] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
