Description

Technical Field

[0001] This utility model relates to the field of circuit board production equipment technology, specifically to a circuit board shunt device. Background Technology

[0002] PCB (Printed Circuit Board), also known as a printed circuit board or printed circuit board, is an important electronic component. It serves as the support for electronic components and provides the electrical connections between them. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. Circuit boards are essential components in the modern electronics industry, used for the electrical connections of electronic components. The production and processing of circuit boards involves multiple steps, including material cutting, drilling, copper plating, image transfer, etching, inspection, and screen printing. Therefore, the process involves the transport of circuit boards, typically via conveyor lines. This transport often involves diversion, for example, to ensure production efficiency, some processes involve multiple devices, requiring the conveyor line to divert the circuit boards to each device. Alternatively, after inspection, circuit boards may be diverted to different areas based on defects. Traditionally, this diversion process is done manually. While robotic arms are now used, with their board-grabbing mechanisms, they not only occupy significant space and are costly, but also require the circuit boards to pause during transfer for gripping, consuming considerable time and impacting the conveyor line's cycle time, resulting in low transport efficiency.

Detailed Implementation

[0027] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1 to 4 This utility model provides a circuit board distribution device, including a machine base, a first conveying mechanism 2, a distribution mechanism 3, a second conveying mechanism 4, and a receiving mechanism 5. The first conveying mechanism 2, the distribution mechanism 3, and the second conveying mechanism 4 are arranged sequentially, and the receiving mechanism 5 is located above the second conveying mechanism 4.

[0030] A diversion mechanism 3 is connected to one end of the first conveying mechanism 2. The diversion mechanism 3 includes a diversion conveying assembly 31 rotatably connected to the first conveying mechanism 2 and a drive assembly 32 mounted on the frame 1. The drive assembly 32 is drively connected to the diversion mechanism 3 and drives the diversion mechanism 3 to rotate relative to the first conveying mechanism 2. The drive assembly 32 drives the diversion conveying assembly 31 to rotate upward, that is, to raise one end of the diversion conveying assembly 31.

[0031] The receiving mechanism 5 is disposed on the frame 1 and is located above the second conveying mechanism 4. When the driving component 32 drives the diversion conveying component to rotate upward, the end of the diversion conveying component 31 and the receiving mechanism 5 are at the same height. At this time, when the circuit board passes through the diversion conveying component 31, it can flow to the receiving mechanism 5, thereby realizing the diversion of the circuit board during conveying.

[0032] The diversion and conveying assembly includes a diversion and conveying frame 311 rotatably connected to the first conveying mechanism, a plurality of diversion and conveying components 312 disposed on the diversion and conveying frame 311, and a first driving member 313 disposed below the diversion and conveying frame 311.

[0033] The drive assembly 32 includes a lifting drive 321 mounted on the frame 1 and a connecting end 322 located at the bottom of the diversion and conveying frame 311. The output end of the lifting drive 321 and the connecting end 322 are rotatably connected. In this embodiment, the lifting drive 321 is a cylinder, the end of which is also rotatably connected to the frame 1. The piston rod end of the cylinder is rotatably connected to the connecting end 322. When the piston rod is pushed out, the diversion and conveying assembly 31 is lifted and rotates upward.

[0034] The circuit board diversion device includes a pressure plate 631 mechanism 6 mounted on the diversion conveying frame 311. The pressure plate 631 mechanism 6 includes two pressure plate 631 supports 61 respectively mounted on both sides of the diversion conveying frame 311, a top plate 62 mounted on the pressure plate 631 supports 61, and a plurality of pressure plate 631 assemblies 63 evenly disposed on the bottom surface of the top plate 62. The pressure plate 631 assemblies 63 provide a clamping force to the circuit board from the top, so that when the diversion conveying assembly rotates upward to an inclined state, the circuit board can maintain friction with the diversion conveying assembly 312 under the clamping force, ensuring that the circuit board will not slip and can be conveyed normally. The pressure plate 631 assemblies 63 need to cover the entire width direction of the diversion conveying assembly to ensure contact with circuit boards within this size range.

[0035] The pressure plate 631 assembly 63 includes a pressure plate 631 connected to the top plate 62, a guide rod 632 connected to the pressure plate 631, a fixing plate 633 connected to the bottom of the guide rod 632, and a plurality of pressure rollers 634 connected to one side of the fixing plate 633. A spring 635 is sleeved on the guide rod 632. There is a gap between the pressure rollers 634 and the diversion and conveying assembly 31 for the circuit board to pass through. The spring 635 is disposed between the pressure plate 631 and the fixing plate 633, and the spring 635 provides elastic force to press the fixing plate 633 towards the diversion and conveying assembly, thereby applying a clamping force to the circuit board. In this embodiment, multiple pressure rollers 634 are arranged in a row to ensure that there is always a pressure roller 634 in contact with the circuit board during movement.

The first conveying mechanism 2 includes a first conveying frame 21 disposed on the frame 1, a plurality of first conveying components 22 disposed on the first conveying frame 21, and a second driving member 23 disposed below the first conveying frame 21. The second driving member 23 and the first conveying components 22 are connected in a driving manner.

[0037] The first conveying frame 21 is equipped with a sensor 24 for sensing the circuit board. The sensor 24 can sense whether the circuit board has entered the first conveying mechanism 2. In a specific implementation, the sensor 24 can be an optical fiber sensor 24.

[0038] The second conveying mechanism 4 is disposed on the frame 1. The second conveying mechanism 4 includes a second conveying frame 41, a plurality of second conveying components 42 disposed on the second conveying frame 41, and a third driving member 43 disposed below the second conveying frame 41. The third driving member 43 and the second conveying components 42 are connected in a driving manner. In this embodiment, the second conveying components 42 may adopt the same structure as the diversion conveying component 31, or they may adopt synchronous pulleys.

[0039] The receiving mechanism 5 includes a support frame 51 mounted on the frame 1 and a loading platform 52 mounted on the support frame 51. In this embodiment, the circuit board diversion device is used to divert defective circuit boards, and the loading platform 52 is used to place defective circuit boards. After the defective products are identified in the preceding process, when the defective products arrive at the diversion conveying assembly 31, the diversion conveying assembly 31 rotates upwards, and the circuit boards enter the loading platform 52 from the diversion conveying assembly 31. The circuit boards are stacked on the loading platform 52 for removal by the operator. During the conveying of the circuit boards, the upward rotation of the diversion conveying assembly quickly sends out the defective products without affecting the conveying cycle of the circuit boards. Alternatively, in this embodiment, the loading platform 52 can also be located at the circuit board processing equipment for temporary storage of circuit boards. Specifically, a board feeding mechanism, such as a conveyor wheel, can be installed on the loading platform 52 to feed the circuit boards into the processing equipment.

[0040] In practical use, the first conveying mechanism 2 and the second conveying mechanism 4 are connected to the circuit board conveying line. The diversion conveying component diverts the circuit boards marked in the previous process to the receiving mechanism 5, while the unmarked circuit boards can pass through the diversion conveying component, enter the second conveying mechanism 4, and enter the conveying line from the second conveying mechanism 4 to be conveyed to the next process.

[0047] The circuit board diversion device includes a pressure plate 631 mechanism 6 mounted on the diversion conveying frame 311. The pressure plate 631 mechanism 6 includes two pressure plate 631 supports 61 respectively mounted on both sides of the diversion conveying frame 311, a top plate 62 mounted on the pressure plate 631 supports 61, and a plurality of pressure plate 631 assemblies 63 evenly disposed on the bottom surface of the top plate 62. The pressure plate 631 assemblies 63 provide a clamping force to the circuit board from the top, so that when the diversion conveying assembly rotates upward to an inclined state, the circuit board can maintain friction with the diversion conveying assembly 312 under the clamping force, ensuring that the circuit board will not slip and can be conveyed normally. The pressure plate 631 assemblies 63 need to cover the entire width direction of the diversion conveying assembly to ensure contact with circuit boards within this size range.

[0048] The pressure plate 631 assembly 63 includes a pressure plate 631 connected to the top plate 62, a guide rod 632 connected to the pressure plate 631, a fixing plate 633 connected to the bottom of the guide rod 632, and a plurality of pressure rollers 634 connected to one side of the fixing plate 633.

The spring 635 is disposed between the pressure plate 631 and the fixing plate 633, and the spring 635 provides elastic force to press the fixing plate 633 towards the diversion and conveying assembly, thereby applying a clamping force to the circuit board. In this embodiment, multiple pressure rollers 634 are arranged in a row to ensure that there is always a pressure roller 634 in contact with the circuit board during movement.

When it is necessary to divert circuit boards to different work areas, the second conveying mechanism 4 and the conveyor belt are connected to different conveyor lines. The diversion conveying component can divert circuit boards to the second conveying mechanism 4 and the conveyor belt according to settings or markings, thereby diverting the circuit boards to different areas. For example, if the current process requires diverting circuit boards to two processing machines, the first circuit board can be conveyed to the second conveying mechanism 4, the second circuit board to the conveyor belt, and so on. Of course, the above is only an example of the use of this utility model. In specific implementation, this utility model can be used in any scenario where circuit board diversion is required, and adaptive adjustments can be made according to the actual application scenario. For example, two conveyor belts can be set, and the driving component 32 can be a type that can set the lifting height, setting the lifting height to two levels, each corresponding to a different conveyor belt, thereby realizing the diversion of three paths.
