Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, specifically to a PCB board screening and buffering device. Background Technology

[0002] PCB boards, also known as printed circuit boards, are important electronic components and serve as the support for electronic devices. During PCB production, they need to be screened to remove substandard PCB boards. CN219745584U discloses a PCB screening and buffering device that uses a storage structure to collect defective PCB boards. In use, workers remove the defective PCB boards and place them in a storage basket. A fixing shell supports the basket, and a connecting plate secures the fixing shell to the top of a side panel. When the basket is full, the handle is lifted, causing the basket to be removed from the fixing shell, thus effectively collecting the defective PCB boards.

[0003] The device requires manual sorting of PCBs during use, which results in low sorting efficiency. Furthermore, fatigue can easily occur during long-term operation, and minor problems with PCBs are not easily detected, leading to low sorting accuracy.

[0004] Therefore, it is necessary to invent a PCB board screening and buffering device to solve the above problems. Utility Model Content

The first conveyor belt and the second conveyor belt work together to transport the PCB board, and the testing equipment is used to test the PCB board. When the product is qualified, the second equipment support is in a horizontal state.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figures 1 to 3 The PCB board screening and buffering device shown includes a first device bracket 1 and a second device bracket 2. A first conveyor belt 12 and a second conveyor belt 22 are respectively provided on the surface of the first device bracket 1 and the second device bracket 2. Multiple sets of first drive shafts 11 are rotatably connected inside the first device bracket 1. The first conveyor belt 12 is driven by the multiple sets of first drive shafts 11. A first motor 13 is fixedly installed on the left end of the front surface of the first device bracket 1. The output end of the first motor 13 is fixedly connected to the front end of the left first drive shaft 11 through a coupling. Multiple sets of second drive shafts 21 are rotatably connected inside the second device bracket 2. The second conveyor belt 22 is driven by the multiple sets of second drive shafts 21. A second motor 23 is fixedly installed on the right end of the front surface of the second device bracket 2. The output end of the second motor 23 is fixedly connected to the front end of the right second drive shaft 21 through a coupling. A connecting plate 15 is fixedly connected to the right end of the first device bracket 1. The left end of the second device bracket 2 is rotatably connected to the connecting plate 15. A detection device 14 is provided on the upper side of the first device bracket 1.

[0031] The testing equipment 14 is an optical scanner that inspects PCBs with a large number of integrated electronic components and high density, scanning for fault points on the PCB surface. The first motor 13 drives the first conveyor belt 12 to rotate, and the second motor 23 drives the second conveyor belt 22 to rotate. During use, the operator places the PCBs sequentially at the left end of the first conveyor belt 12. As the first conveyor belt 12 rotates, it transports the PCBs to the right. When the PCBs pass under the testing equipment 14, the testing equipment 14 inspects them and transmits the inspection information to the PLC controller. When the PCBs pass the inspection, the PLC controller adjusts the second equipment support 2 to a horizontal position. When the PCBs fail the inspection, the PLC controller rotates the second equipment support 2 downwards to an inclined position, thus sorting the qualified and unqualified PCBs.

[0032] See Figure 1 , Figure 3 and Figure 4 An adjustment assembly is provided on the lower side of the second equipment bracket 2. The adjustment assembly includes a support frame 3, a first fixed rod 31, a hydraulic cylinder 33, and a second fixed rod 34. The upper end of the support frame 3 is fixedly connected to the connecting plate 15. The first fixed rod 31 is fixedly connected to the inner wall of the support frame 3 near the lower side. A first connecting block 32 is fixedly connected to the right side surface of the first fixed rod 31. The second fixed rod 34 is fixedly connected to the lower surface of the second equipment bracket 2 near the right side. A second connecting block 35 is fixedly connected to the left side surface of the second fixed rod 34. The hydraulic cylinder 33 is inclined with the left side lower than the right side. The left end of the hydraulic cylinder 33 is rotatably connected to the first connecting block 32. The right end of the telescopic rod in the hydraulic cylinder 33 is rotatably connected to the second connecting block 35.

[0033] Specifically, when a product passes inspection, the PLC controller activates hydraulic cylinder 33, causing the telescopic rod in hydraulic cylinder 33 to extend outward. At this time, the telescopic rod in hydraulic cylinder 33 pushes the second fixed rod 34 upward, causing the left end of the second equipment bracket 2 to rotate counterclockwise around the connecting plate 15, rotating the second equipment bracket 2 to a horizontal position. When a product fails inspection, the telescopic rod in hydraulic cylinder 33 retracts inward, pulling the second fixed rod 34 downward, which in turn causes the left end of the second equipment bracket 2 to rotate clockwise around the connecting plate 15, rotating the second equipment bracket 2 to an inclined position for product sorting.

[0034] See Figure 1 and Figure 4 The right side of the second equipment bracket 2 is provided with a first buffer box 4 and a second buffer box 43. Multiple sets of support rods 41 are fixedly connected to the side of the first buffer box 4. Multiple sets of casters 42 are rotatably connected to the lower end of the support rods 41 and the lower surface of the second buffer box 43.

[0035] In addition, when the second equipment bracket 2 is in a horizontal position, the PCB board on its surface will be transported to the inside of the first buffer box 4 for storage. When the second equipment bracket 2 is in an inclined position, the PCB board will be transported to the inside of the second buffer box 43 for storage. Both the first buffer box 4 and the second buffer box 43 are equipped with casters 42 on their lower sides, which facilitates the movement and transfer of the first buffer box 4 and the second buffer box 43 and improves the convenience of operation.

[0036] The working principle of this utility model is as follows: By using the testing equipment 14 to test the PCB board, the testing accuracy is improved. At the same time, the hydraulic cylinder 33 is used to adjust the angle of the second equipment support 2, so that qualified products are transported to the first buffer box 4 and unqualified products are transported to the second buffer box 43, thereby realizing automatic product sorting and effectively improving the accuracy and efficiency of product sorting.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
