Description

Technical Field

[0001] This utility model is a blind buried hole alignment device for circuit boards, belonging to the technical field of alignment equipment. Background Technology

[0002] With the rapid development of microelectronics technology, circuit board manufacturing is moving towards multi-layered and multifunctional designs. Consequently, printed circuit patterns are becoming increasingly finer, with finer conductors, microvias, and narrower pitch. Blind vias are electroplated holes that connect the outermost layer of a printed circuit board to adjacent inner layers. Because the opposite layer is not visible, they are called blind through-holes. A blind via is essentially a through-hole leading to the surface of the printed circuit board. Located on the top and bottom surfaces of the board, blind vias have a certain depth and are used to connect surface layer circuits to underlying inner layer circuits. Existing blind via alignment equipment generally does not allow for quick clamping and fixing of blind vias, significantly impacting the operating speed of the alignment equipment. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a circuit board blind buried hole alignment device.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0020] Please see Figure 1-4 This utility model provides a technical solution for a circuit board blind hole alignment device, including a lower support body 1, an outer shell 2 mounted on the lower support body 1, a sealing door 4 slidably connected to the outer shell 2, and a handle 3 mounted on the sealing door 4. By mounting the outer shell 2 on the lower support body 1 and using the handle 3 in conjunction with the sealing door 4, it is convenient to seal the outer shell 2 during processing. An alignment processing device body 5 is mounted on the top inside the outer shell 2, and a cross sliding assembly 6 is mounted on the bottom inside the outer shell 2. A circuit board positioning assembly is mounted on the cross sliding assembly 6.

At the same time, the circuit board positioning assembly facilitates the positioning and clamping of the circuit board.

[0021] See Figure 2The cross-shaped sliding assembly 6 includes a lower support base plate 7, an upper sliding support plate 9, and a top mounting plate 10. The bottom of the lower support base plate 7 is fixed to the inner bottom of the outer shell 2 by fixing feet 8. A forward and reverse motor 11 is installed between the lower support base plate 7 and the upper sliding support plate 9, and between the upper sliding support plate 9 and the top mounting plate 10. A support plate 12 is installed at the other end of the lower support base plate 7 and the upper sliding support plate 9. A lead screw 13 is rotatably connected between the output end of the forward and reverse motor 11 and the support plate 12. A connecting block is threaded on the lead screw 13. The connecting block is connected to the bottom of the corresponding upper sliding support plate 9 and the top mounting plate 10. A guide rail 14 is installed on both the lower support base plate 7 and the upper sliding support plate 9. A sliding block 15 is provided at the bottom of both the upper sliding support plate 9 and the top mounting plate 10, which is slidably connected to the guide rail 15.

[0022] See Figure 3 The circuit board positioning assembly includes a support platform 18 fixed on a top mounting plate 10. A processing table 23 for placing the circuit board is located at the center of the support platform 18. A double-headed telescopic cylinder 19 is fixed on the support platform 18.

A guide crossbar 27 is fixed between the support side blocks 26. Sliding guide blocks 28 are symmetrically arranged on the guide crossbar 27. The sliding guide blocks 28 are fixedly connected to one end of the connecting plate 21. When the circuit board is placed in the center of the processing table 23, the double-headed telescopic cylinder 19 drives the push blocks 20, causing the clamping plate 22 on the connecting plate 21 to move synchronously under the action of the sliding guide blocks 28 and the guide crossbar 27, thereby achieving the effect of clamping and releasing.

[0023] See Figure 4 The lower support body 1 has a storage compartment, and a control panel 30 is connected to the lower support body 1 via a rotating connecting frame 29. The storage compartment provides convenient storage for everyday items, while the control panel 30 facilitates data input to control the operation of the entire device.
