Description

Technical Field

[0001] The utility model belongs to the technical field of positioning tooling, in particular to a copper-embedded production positioning device for a multi-layer circuit board. Background Art

[0002] The buried copper process refers to embedding conductive copper foil in the inner layer of the PCB board to achieve circuit connection between different layers. This process can effectively reduce the surface routing of the circuit board and improve the wiring density and signal transmission performance of the circuit board. At the same time, since the conductive layer is embedded inside the board, it can also enhance the mechanical strength and heat resistance of the circuit board; the processing technology includes: designing PCB circuit diagrams, making PCB boards, grooving and drilling, buried copper treatment, pressing, cleaning, etc., among which the buried copper treatment is to embed the conductive copper foil into the opened grooves and holes, and perform necessary compaction and fixing treatment. Then, a conductive layer is covered on the surface of the copper foil by chemical copper deposition or electroplating to achieve circuit connection between different layers;

[0003] In order to ensure the copper embedding effect and reliability, the circuit board needs to be fixed before copper embedding. Most of the existing methods are to place the circuit board on the workbench, and then use the screw to drive the pressing plate to press the circuit board on the workbench. The pressing of the two ends of the circuit board is an independent manual operation structure. The force of manually turning the screw to press is not easy to control, and it is easy to be too loose or too tight, which is not conducive to the reliable and safe positioning of the circuit board. Secondly, the existing positioning tooling needs to be customized according to the size of the circuit board, and the adaptability is poor;

[0004] In order to solve the above problems, the present application proposes a multi-layer circuit board buried copper production positioning device. Utility Model Content

The bottom plate 4, the side panel 5, and the clamping plate 6 can adjust the spacing on the workbench 1 at the same time. A notch block 12 is fixed on the slide 16, and a driving rod 13 slides in the notch block 12. The driving rod 13 is perpendicular to the workbench 1 and can move in the horizontal and vertical directions. There are two driving rods 13. An electric cylinder 14 that can drive the two driving rods 13 to rise and fall synchronously is also installed at the bottom of the transmission chamber 2. A slide plate 7 is fixed at the bottom of the bottom plate 4.

[0028] Among them, a rotating screw 8 is provided inside the transmission chamber 2, and an internal thread block 9 is fitted on the external thread of the screw 8. A connecting rod 10 is hinged between the internal thread block 9 and the slide plate 7. A servo motor 11 with an output end fixed to the screw 8 is installed inside the transmission chamber 2. In this embodiment, there are two internal thread blocks 9 and four connecting rods 10, which effectively ensure the adjustment stability and accuracy between the two base plates 4.

[0029] Among them, the workbench 1 is provided with an adjustment groove 18 for the sliding of the base plate 4 and a slide groove 19 for the sliding of the slide plate 7. The lead screw 8 and the internal thread block 9 are spirally driven and drive the base plate 4 to slide in the adjustment groove 18 under the action of the connecting rod 10. In this embodiment, the base plate 4 is set in the adjustment groove 18. When the circuit board is clamped, the bottom is in contact with the base plate 4 and the workbench 1 at the same time, ensuring the stability of the circuit board and avoiding bending. At the same time, the circuit board can also be pressed by this positioning tool.

[0030] Among them, the clamping plate 6 and the notch block 12 are both flipped 90°, and the top of the driving rod 13 can rotate and slide inside the notch block 12. In this embodiment, the clamping plate 6 is in a horizontal state when it is pressed, and is in a vertical state when it is completely released. The clamping plate 6 in the vertical state does not affect the picking and placing of the circuit board on the workbench 1.

[0031] Among them, a linkage plate 15 is fixed to the output end of the electric cylinder 14, and slides 16 are fixed to both ends of the linkage plate 15. The slides 16 are vertically distributed to the driving rod 13. In this embodiment, two slides 16 are connected at the same time through the linkage plate 15, and the two slides 16 are respectively connected to the clamping plates 6 at both ends to ensure the consistency of the clamping force of the clamping plates 6 at both ends, thereby ensuring the clamping effect of the circuit board.

[0032] Among them, a slider 17 sliding in the slide seat 16 is fixed at the bottom of the driving rod 13, and the driving rod 13 slides horizontally in the slide seat 16 through the slider 17. In this embodiment, the setting of the slide seat 16 and the slider 17 neither affects the position adjustment of the splint 6 nor affects the synchronous driving of the driving rod 13 by the electric cylinder 14 after adjustment, and has strong flexibility.

In this embodiment, the guide component can be composed of a guide rod, a guide sleeve, etc., mainly to ensure the structure and matching stability of the linkage plate 15, the slide seat 16, and the driving rod 13, thereby ensuring the reliable clamping of the splint 6.

[0034] It can be understood that first, a clamping plate 6 with an adjustable spacing is set, which can be adjusted according to the size of the circuit board and has better adaptability. Secondly, the driving of the two clamping plates 6 is simultaneously realized through an electric cylinder 14 to ensure the clamping consistency and strength. Finally, the adjustment and stable clamping are linked, and the clamping plate 6 can be adjusted while reliably maintaining the clamping stability.

[0035] A specific application of this embodiment is: Figure 1 As shown, the circuit board is placed on the workbench 1, and then the servo motor 11 is started. The servo motor 11 drives the lead screw 8 to rotate, and the lead screw 8 drives the internal thread block 9 to move through the thread. During the movement of the internal thread block 9, the sliding plate 7 is driven to slide in the sliding groove 19 through the connecting rod 10. At the same time, the bottom plate 4 slides in the adjusting groove 18, and the side plate 5, the clamping plate 6, and the driving rod 13 follow and slide synchronously. At this time, the slider 17 also slides in the sliding seat 16. The side plate 5 and the two sides of the circuit board are limited. The servo motor 11 stops working, and the electric cylinder 14 drives the linkage plate 15 and the sliding seat 16 to move upward synchronously. The sliding seat 16 drives the driving rod 13 to move upward, and the driving rod 13 moves inside the notch block 12, and then drives the clamping plate 6 to move downward under the action of the lever principle until the bottom of the clamping plate 6 clamps the circuit board between the bottom plate 4, the side plate 5, and the clamping plate 6, as shown in FIG. Figure 2 In the state shown, copper embedding work can be carried out;

[0036] Disengagement positioning: drive the electric cylinder 14 in the reverse direction, the linkage plate 15 and the driving rod 13 move downward, the lever principle drives the clamping plate 6 to move upward, the clamping plate 6 moves away from the top of the circuit board, and the circuit board can be taken out;

[0037] When the circuit boards of the same size are processed continuously, there is no need to adjust the positions of the two clamping plates 6, and the processing can be continued directly according to the first adjusted position.
