Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment, specifically a blind hole forming device for circuit board processing. Background Technology

[0002] During circuit board manufacturing, through-holes and blind vias need to be installed on the circuit board. Blind vias are similar to through-holes, but blind vias only partially penetrate the PCB. They connect the top layer to the inside without penetrating the PCB. They are usually used to connect circuits between the surface layer and the inner layer and are very suitable for multi-layer PCBs with limited space. The manufacturing process of blind vias is relatively complex. If the drilling depth is not carefully controlled, it can easily cause difficulties in electroplating inside the hole. Therefore, it is advisable to drill the holes for the circuit layers that need to be connected in the individual circuit layers first, and then glue them together.

[0003] According to the patent document CN102784831A, a blind hole plate stamping forming device is disclosed, which includes a crank-connecting rod punch press. The bed is divided into two parts, and a die is provided between the two beds. The bed surface on one side of the die is covered by a guide rail. The bed surface on the other side of the die is provided with a blind hole positioning body and a guide rail from near to far. The surface of the positioning body has a concave-convex surface consistent with the punch and die. When this technical solution is used, it relies on the impact kinetic energy of the punch to quickly realize the blind hole processing of the corresponding forming surfaces of the punch and die. With the use of a movable and restrictive positioning worktable, accurate and continuous production processing can be achieved. Regarding the above technical solution, although the stamping is realized, the stamping position cannot be squeezed and polished after stamping, which is inconvenient when using it. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a blind hole forming device for circuit board processing, thereby solving the problems mentioned in the background art. This utility model has a novel structure. In use, the electrode tube is stamped by a tapered column. After the electrode tube is impacted, the diameter of the top is larger than the diameter of the opening. Later, the drive motor drives the tapered column and the fixed cylinder to rotate and complete the extrusion, so that the top of the electrode tube is relatively flat with the circuit board.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blind hole forming device for circuit board processing, comprising a base, a support seat welded to the base, an opening in the support seat, a clamping plate movably mounted inside the opening, a movable seat movably mounted between the clamping plates, a lifting mechanism fixedly mounted on the movable seat, a sliding groove in the inner wall of the opening, a slider movably mounted inside the sliding groove, a pushing mechanism fixedly mounted on the slider, a fixing groove in the base, and a fixing column movably mounted inside the fixing groove.

[0006] Furthermore, the fixing post is installed inside the fixing groove via a reset mechanism. The fixing post has a slot, and a limit post is movably installed inside the slot.

[0007] Furthermore, the inner wall of the clamping plate has a groove, and a protrusion is movably installed inside the groove. The protrusion is fixedly installed on the side of the movable seat, and a fixing plate is fixed at one end of the lifting mechanism.

[0008] Furthermore, a connecting column is fixed on the fixing plate, a support plate is fixed at one end of the connecting column, a drive motor is fixedly installed on the support plate, and a tapered column is fixedly installed on the drive motor.

[0009] Furthermore, a fixing cylinder is fixed on the conical column, a circuit board is movably mounted on the conical column, an electrode tube is movably mounted on the circuit board, and the circuit board is movably mounted between the fixing columns.

[0010] Furthermore, a fixing block is movably mounted on the limiting post, the fixing block has a threaded hole, a threaded post is rotatably mounted inside the threaded hole, one end of the threaded post is fixed on the limiting post, and a limiting block is movably mounted on the side of the fixing block.

[0011] Furthermore, the fixing block is movably installed inside the slot, and a limiting groove is formed on the inner wall of the slot. The limiting block is installed inside the limiting groove by a tension mechanism, and a torsion spring shaft is installed between the fixing block and the limiting block.

[0012] Furthermore, a support mechanism is fixed on the inner wall of the opening, one end of the support mechanism is fixed to the clamping plate, and a displacement mechanism is fixedly installed on the support base, one end of the displacement mechanism is fixed to the clamping plate.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the electrode tube is stamped by a tapered column during use. After the electrode tube is impacted, the diameter of the top is larger than the opening. Later, the drive motor drives the tapered column and the fixed cylinder to rotate and complete the extrusion, so that the top of the electrode tube is relatively flat with the circuit board.

[0015] In this invention, a circuit board is installed between fixed posts. A support mechanism presses against the fixed posts, and the fixed posts complete the compression and limiting of the circuit board. Then, the limiting posts move downward under the pull of the tension mechanism. The limiting posts complete the vertical compression and fixing of the circuit board from top to bottom. The limiting posts rotate on the fixed block through threaded posts. The rotation adjusts the contact area between the limiting posts and the circuit board, so as to achieve contact compression of different side widths of the circuit board.

[0016] In this invention, after the clamping plate loses its inward pressing force, the movable seat loses the pressing and limiting effect of the clamping plate and is removed from the clamping plate. After removal, the diameter of the tapered column is selected and replaced. The movable seat is pushed to move left and right by the displacement mechanism, and the displacement mechanism pushes the clamping plate and the movable seat to move back and forth, thus completing the rapid adjustment of the stamping position.

[0024] In this embodiment, a groove 27 is formed on the inner wall of the clamping plate 6, and a protrusion 28 is movably installed inside the groove 27. The protrusion 28 is fixedly installed on the side of the movable seat 9. A fixing plate 21 is fixed at one end of the lifting mechanism 20. A connecting column 23 is fixed on the fixing plate 21. A support plate 22 is fixed at one end of the connecting column 23. A drive motor 24 is fixedly installed on the support plate 22. A conical column 29 is fixedly installed on the drive motor 24.

The circuit board 31 is movably installed between the fixing columns 11. The bottom of the fixing cylinder 30 squeezes the electrode tube 32 to ensure that the top of the electrode tube 32 is wrapped around the circuit board 31.

[0025] In this embodiment, a fixing block 15 is movably mounted on the limiting post 13. The fixing block 15 has a threaded hole, and a threaded post 16 is rotatably mounted inside the threaded hole. One end of the threaded post 16 is fixed to the limiting post 13. A limiting block 17 is movably mounted on the side of the fixing block 15. The fixing block 15 is movably mounted inside the slot 12.

The lifting mechanism 20 is started to push the conical column 29 to move downward. The conical column 29 moves downward to press the electrode tube 32. After the electrode tube 32 is pressed, a blind hole circuit connection is formed. After the conical column 29 is pressed, the drive motor 24 drives the conical column 29 and the fixed cylinder 30 to rotate to complete the extrusion and grinding of the top of the electrode tube 32. The extrusion makes the bottom of the electrode tube 32 fit and distribute with the circuit board 31.
