Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to an automatic feeding mechanism for PCB drilling. Background Technology

[0002] Drilling is a critical process in the manufacturing of printed circuit boards (PCBs). It is used to create vias connecting different circuit layers and through-holes for mounting components. To ensure the accuracy of subsequent multilayer board lamination, precise positioning, and automated assembly, specific positioning holes are usually pre-drilled on the PCB before the actual machining of functional holes. These positioning holes are crucial; they serve as reference points for all subsequent machining and assembly processes, and their positional accuracy directly affects the quality and yield of the final product. Therefore, accurately and efficiently machining these positioning holes on a drilling machine is a fundamental requirement of the PCB manufacturing process.

[0003] However, for a long time, the loading and unloading process for drilling PCB positioning holes has generally relied on manual operation. Operators need to manually move the PCBs to be processed one by one onto the processing platform of the drilling machine, and after the positioning holes are processed, manually remove the PCBs from the platform. This method is not only inefficient in positioning, but also very labor-intensive. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where PCB drilling relies on manual operation, and to propose an automatic feeding mechanism for PCB drilling.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] An automatic feeding mechanism for PCB drilling includes a drilling machine body and a support plate fixedly mounted on the processing end of the drilling machine body. A fixed frame is fixedly mounted on one side of the processing end of the drilling machine body. A driving component is mounted on the fixed frame. A placement plate is slidably mounted on the fixed frame. Multiple clamping rods for placing circuit boards are slidably mounted on the upper surface of the placement plate. A moving component is mounted on the placement plate. The driving component is used to drive the moving component to control the moving direction of the placement plate. When the placement plate moves to the support plate position, the clamping rods rotate to lay the circuit board flat on the support plate.

[0007] Preferably, the moving component includes a moving groove and a guide groove formed on the inner wall of the moving groove, both side by side on the upper surface of the support plate. A moving block is slidably disposed in the moving groove. The upper end of the moving block is fixedly connected to the lower surface of the placement plate. A rotating rod is fixedly disposed at one end of the moving block. A push rod is fixedly disposed at one end of the rotating rod. A guide rod is fixedly disposed on the push rod. The guide rod is located in the guide groove.

[0008] Preferably, the guide groove includes a straight groove and an arc-shaped groove formed on the inner wall of the moving groove, wherein the straight groove and the arc-shaped groove are connected.

[0009] Preferably, two positioning blocks are fixedly provided on the upper surface of the support plate, and the positioning blocks are L-shaped.

[0010] Preferably, the driving component includes a linear motor fixedly mounted on the upper surface of the fixed frame, and a limiting frame is fixedly provided on the slider of the linear motor, the inner wall of the limiting frame being in contact with the perimeter of the placement plate.

[0011] Preferably, the driving component further includes a cylinder fixedly mounted on a fixed frame, the output end of which is used to push the push rod to move.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, by setting up a horizontally sliding placement plate and a rotatable clamping rod structure, automatic feeding and precise positioning of circuit boards during drilling are achieved. After the moving component controls the placement plate to move above the support plate, the clamping rod rotates to lay the circuit board flat in the processing area, replacing the traditional manual placement and adjustment operation mode. This design significantly reduces the labor intensity of operators, avoids board position deviations caused by human factors, and thus improves the processing accuracy of positioning holes.

[0023] Example: This example provides an automatic feeding mechanism for PCB drilling. See [link to example]. Figure 1-4 Specifically, it includes a drilling machine body 1, a support plate 11 fixedly mounted on the processing end of the drilling machine body 1, a fixed frame 12 fixedly mounted on one side of the processing end of the drilling machine body 1, a driving component mounted on the fixed frame 12, a placement plate 13 slidably mounted on the fixed frame 12, a plurality of clamping rods 14 for placing circuit boards slidably mounted on the upper surface of the placement plate 13, a moving component 2 mounted on the placement plate 13, the driving component is used to drive the moving component 2 to control the moving direction of the placement plate 13, and when the placement plate 13 moves to the position of the support plate 11, the clamping rods 14 rotate to lay the circuit board flat on the support plate 11.

[0024] In this embodiment, a fixing frame 12 is provided on the side of the processing area of ​​the drilling machine body 1. The placement plate 13 on the fixing frame 12 can move parallel to the drilling machine body 1. The clamping rod 14 on the placement plate 13 is used to install circuit boards. The circuit board is inserted into the groove of the clamping rod 14 and fixed by the friction between the inner wall of the clamping rod 14 and the circuit board. Each clamping rod 14 moves towards the support plate 11 through the moving component 2, and the circuit board is sequentially sent to the support plate 11. The circuit board on the support plate 11 is facing the drill bit, and the drill bit drills positioning holes in the circuit board. After the circuit board is drilled, it will move to the placement plate 13. Then the placement plate 13 will move a certain distance, so that the next clamping rod 14 can drive the circuit board towards the support plate 11, realizing automatic feeding of the circuit board. The placement plate 13 can be removed from the fixing frame 12. The placement plate 13 and the clamping rod 14 facilitate the transfer of circuit boards between various devices.

[0025] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the movable component 2 includes a movable groove 24 arranged side by side on the upper surface of the support plate 11 and a guide groove 3 arranged on the inner wall of the movable groove 24. A movable block 21 is slidably arranged in the movable groove 24. The upper end of the movable block 21 is fixedly connected to the lower surface of the placement plate 13. A rotating rod 22 is fixedly arranged at one end of the movable block 21. A push rod 23 is fixedly arranged at one end of the rotating rod 22. A guide rod 33 is fixedly arranged on the push rod 23. The guide rod 33 is located in the guide groove 3.

[0026] In this embodiment, the moving block 21 and the inner wall of the moving groove 24 are in contact. The lower end of the moving block 21 is cylindrical and the upper end is rectangular. The moving block 21 slides along the moving groove 24, which restricts the lateral movement of the locking rod 14. When the moving block 21 moves out of the moving groove 24, the cylindrical rotating rod 22 is in contact with the inner wall of the moving groove 24. Through the cooperation of the guide rod 33 and the guide groove 3, the rotating rod 22 rotates in the moving groove 24. The rotating rod 22 drives the moving block 21 and the locking rod 14 to rotate synchronously, so that the vertical circuit board becomes horizontal and is laid flat on the support plate 11, which is convenient for drilling.

[0027] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the guide groove 3 includes a straight groove 31 and an arc-shaped groove 32 formed on the inner wall of the moving groove 24, with the straight groove 31 connected to the arc-shaped groove 32.

[0028] In this embodiment, the lower end of the guide rod 33 is in contact with the inner walls of both the straight groove 31 and the arc groove 32. When the clamping rod 14 is located on the placement plate 13, the guide rod 33 is in the straight groove 31. When the clamping rod 14 moves the circuit board toward the support plate 11, the guide rod 33 moves synchronously through the push rod 23. When the guide rod 33 moves along the straight groove 31 to the position of the arc groove 32, the moving block 21 leaves the moving groove 24. Through the restriction of the arc groove 32, the push rod 23 drives the rotating rod 22 to rotate. The rotating rod 22 drives the moving block 21 and the clamping rod 14 to rotate synchronously, so that the circuit board inside the clamping rod 14 is laid on the support plate 11.

[0029] In the specific implementation process, such as Figure 1 and Figure 2 As shown, two positioning blocks 4 are fixedly provided on the upper surface of the support plate 11, and the positioning blocks 4 are L-shaped.

[0030] In this embodiment, after the lever 14 drives the circuit board to rotate, the circuit board will stop inside the two positioning blocks 4. The two positioning blocks 4 and the lever 14 cooperate to form a concave shape, which limits the lever 14 and improves the stability during drilling.

[0031] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the driving component includes a linear motor 5 fixedly mounted on the upper surface of the fixed frame 12. A limiting frame 51 is fixedly provided on the slider of the linear motor 5, and the inner wall of the limiting frame 51 is in contact with the periphery of the placement plate 13.

[0032] In this embodiment, the linear motor 5 is existing technology and is used to drive the entire placement plate 13 to move, causing the latches 14 on the placement plate 13 to move sequentially to designated positions, and causing the latches 14 to drive the circuit board from the designated positions toward the support plate 11. The placement plate 13 is locked in the cross-shaped limiting frame 51, which facilitates the removal of the entire placement plate 13.

[0033] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the driving component also includes a cylinder 6 fixedly mounted on the fixed frame 12, and the output end of the cylinder 6 is used to push the push rod 23 to move.

[0034] In this embodiment, the cylinder 6 is inserted into the groove at the end of the push rod 23 by the output end of the cylinder 6. The cylinder 6 pushes the push rod 23 to move, which is used to drive the movement of the clamping rod 14. After the output end of the cylinder 6 enters the push rod 23, it generates friction with the inner wall of the push rod 23 and remains in the push rod 23. When the guide rod 33 on the push rod 23 reaches the end of the straight groove 31, the pulling force of the cylinder 6 will leave the push rod 23.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
