Description

Technical Field

[0001] The utility model relates to the technical field of circuit board printing and processing, in particular to an automatic board feeding machine for printed circuit board processing. Background Art

[0002] Printed circuit boards are the support and electrical connection carrier of electronic components. They are made using electronic printing technology. For batch printing of circuit boards, it is usually necessary to place the circuit boards to be printed one by one onto a conveyor belt and transport them to the printing mechanism for printing.

[0003] For example, the Chinese patent authorization announcement number CN207827193U states, "The technical problem to be solved is that the machines mentioned in the background art generally use ordinary conveyor belt devices for feeding materials, and a separate clamping tool is required to clamp the printed circuit boards. Different conveyor devices are required for circuit boards of different sizes, which increases the production cost of the enterprise."

[0004] The technical solution adopted in the above-mentioned reference document is a feeding device for circuit board processing, comprising two symmetrically arranged feeding units, with a distance between the two feeding units, and the distance is adjusted by a lower connecting rod;

[0005] However, when the above-mentioned circuit boards are printed and conveyed, they are usually clamped manually or by equipment and placed one by one on the surface of the conveyor belt of the conveyor mechanism for transportation. The former has low placement efficiency, and the spacing between the circuit boards on the conveyor belt is misaligned, which affects the subsequent printing of the circuit boards. After the circuit boards are clamped by the equipment, the position deviation of the circuit boards occurs at the conveyor belt printing mechanism, and they need to be straightened by the positioning mechanism, which has a greater impact on the subsequent processing of the circuit boards. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic board feeding machine for printed circuit board processing, which can automatically feed batches of stacked circuit boards onto a conveyor belt, and after the circuit boards are fed, the circuit boards and the printing mechanism are accurately positioned, making it more convenient for further processing.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic board feeding machine for printed circuit board processing, comprising a frame, a conveying mechanism, and a material box, wherein a side panel is integrally formed on one side of the frame, a stroke cylinder is fixedly installed on the back of the side panel, a rack is fixedly connected to the telescopic end of the stroke cylinder, a gear is rotatably installed on the back of the side panel through a rotating shaft, a turntable is fixedly sleeved on the front end of the gear rotating shaft, circuit boards are placed at equal intervals inside the material box, a lifting block is movably installed at the bottom of the material box, a swing plate is rotatably installed at the inner corner of one side of the front side of the side panel, a movable plate is slidably installed inside the swing plate, a lifting cylinder is fixedly installed on the bottom end of the movable plate, and a suction cup is fixedly connected to the telescopic end of the lifting cylinder.

[0008] Preferably, a printing mechanism is installed in the middle of the frame, and the printing mechanism is used to print the circuit boards transported by the top of the conveying mechanism.

[0009] Preferably, a guide rail is fixedly installed on the back side of the side panel, and the rack is slidably installed in the guide rail.

[0010] Preferably, the outer edge of the rack is meshed with the outer edge of the gear.

[0011] Preferably, the material box is located at one end of the conveying mechanism, and the size of the inner cavity of the material box matches the size of the circuit board.

[0012] Preferably, a lifting cylinder is fixedly installed on the bottom of the inner wall of the material box, and the telescopic end of the lifting cylinder is fixedly connected to the bottom of the lifting block.

[0013] Preferably, the movable plate is an L-shaped structure, a pin is fixedly installed on one side of the front of the movable plate, and the swing plate is movably sleeved outside the pin.

[0014] Preferably, a vacuum generator is fixedly installed on the telescopic end of the lifting cylinder, and the vacuum generator is used in conjunction with the suction cup.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model relates to a method for stacking circuit boards in batches in a material box. When the circuit boards are put onto the conveyor belt of the conveying mechanism, the lifting cylinder can lift the stacked circuit boards upwards with the lifting block until they are flush with the top of the material box, so that the circuit boards to be put in can be in a straightened state on the top of the material box, and the telescopic end of the stroke cylinder drives the turntable back and forth on the front of the side plate through the rack transmission gear, so that the swing plate and the movable plate cooperate to swing back and forth between the material box and the conveying mechanism.
