Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit boards, in particular to a drilling device for processing core boards. Background Art
[0002] Circuit boards such as PCB and HDI boards are usually formed by laminating multiple layers of core boards. During the production of circuit boards, core board drilling is usually involved. Currently, X-Ray drilling machines are used to drill holes in core boards to improve drilling accuracy. The process of drilling holes in core boards by existing X-Ray drilling machines is as follows: multiple layers of core boards to be drilled are stacked on the workbench, and one of the core boards located in the inner layer is provided with a target. The X-Ray drilling machine detects the target through X-Ray to achieve positioning, and drills holes in the core board so that the core board forms a positioning hole corresponding to the target.
[0003] For example, a Chinese patent with the announcement number CN106973493A discloses a method for manufacturing a PCB and a PCB, and discloses a method for processing deep micro blind holes in a PCB, including the following steps: selecting one of the core boards from a number of core boards and providing an X-ray alignment target for identification by an X-ray drilling machine, and a target PAD corresponding to the blind hole. Pressing a number of core boards together to form a laminated board, wherein the core board provided with the alignment target and the X-ray alignment target is in the inner layer of the laminated board; then the X-ray drilling machine scans and grabs each X-ray alignment target corresponding to each location on the laminated board through X-ray, calculates the center point of each X-ray alignment target, and then drills the target hole. The CCD drilling machine grabs the target hole for alignment, and then determines the drilling position of the blind hole target PAD corresponding to the core board on the laminated board surface by an automatic adjustment compensation method, and then drills the blind hole to improve the drilling accuracy. However, the above-mentioned PCB deep micro blind hole processing method has the following problems: since the X-ray alignment target and the target PAD are set on the core board, the X-ray alignment target and the target PAD cannot be reused, so each time a multi-layer core board is drilled, the X-ray alignment target and the target PAD need to be pre-processed on one of the core boards, which affects the efficiency of the core board drilling. In view of this, the utility model proposes a drilling device for processing the core board to solve the above-mentioned problem. Utility Model Content
[0004] The utility model overcomes the shortcomings of the above-mentioned technology and provides a drilling device for processing core plates.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The workbench is provided with a stopper on the outer periphery of the jig plate for preventing the core plate from moving horizontally relative to the jig plate. The jig plate is provided with a target. An X-Ray drilling machine is provided above the jig plate, the X-Ray drilling machine realizes positioning by detecting the target through X-Ray, and drills holes in the core plate located above the target, so that the core plate forms a positioning hole corresponding to the target.

The target of the jig plate can be reused for X-Ray drilling positioning, and there is no need to set another target on the core plate, thereby improving the drilling efficiency of the core plate. In addition, the stopper prevents the core plate from moving horizontally relative to the jig plate, avoiding the situation where the drilling is offset due to the movement of the core plate during the drilling process.

[0021] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:
[0022] Reference Figure 1-3 , an embodiment of a drilling device for processing a core plate of the utility model is proposed:
[0023] A drilling device for processing a core plate includes a workbench 1, and the workbench 1 is provided with a jig plate 2. The length and width of the jig plate 2 are respectively consistent with the length and width of the core plate 3. At least one layer of core plate 3 is stacked directly above the jig plate 2, and the workbench 1 is provided with a stopper on the outer periphery of the jig plate 2 for preventing the core plate 3 from moving horizontally relative to the jig plate 2, and the jig plate 2 is provided with a target. An X-Ray drilling machine (not marked in the attached drawings) is provided above the jig plate 2, and the X-Ray drilling machine realizes positioning by detecting the target through X-Ray, and drills holes in the core plate 3 located above the target, so that the core plate 3 forms positioning holes corresponding to the target. In the prior art, each time the X-Ray drilling machine drills holes in the stacked core plates, it is necessary to process the target on the inner core plate in advance, and the target cannot be reused. The target of the jig plate 2 of the utility model can be repeatedly used for X-Ray drilling positioning, and there is no need to set another target on the core plate 3, thereby improving the drilling efficiency of the core plate 3, and is particularly suitable for drilling a large number of core plates. The utility model uses an X-Ray drilling machine to drill holes in the core plate 3, and cooperates with the stopper to limit the core plate 3, so that the drilling accuracy of the drilling equipment is improved.
[0024] like Figure 2 As shown, the target is a target hole 21 with a simple structure. Specifically, the target hole 21 vertically penetrates the fixture plate 2, and the diameter of the target hole 21 is larger than the diameter of the positioning hole to avoid damage to the target hole 21 during the drilling process of the X-Ray drilling machine.
[0025] The blocking member is a vertical baffle plate 4 with a simple structure. The stacked core plates 3 are not higher than the vertical baffle plate 4, which effectively prevents the core plates 3 from moving horizontally relative to the fixture plate 2.
[0026] Because the core plate 3 is usually a rectangular plate, the jig plate 2 is a rectangular plate, and vertical baffles 4 are provided on four sides of the jig plate 2 so that the jig plate 2 is fixed on the workbench 1. There is a gap 41 between adjacent vertical baffles 4, and the gap 41 facilitates the removal of the core plate 3 after drilling.
[0027] Specifically, the jig plate 2 is a copper plate, which has a certain rigidity and is not easy to deform. The thickness of the jig plate 2 is not less than 1 mm, so as to avoid the jig plate 2 being too thin and causing the jig plate 2 to warp, and the thickness of the jig plate 2 is not less than 1 mm to ensure that it can support the core plate 3, so that the core plate 3 is spaced from the workbench 1, and the X-Ray drilling machine is prevented from damaging the workbench 1 during the drilling process.
[0028] In the present invention, the fixture plate 2 is provided with four target holes 21 . In other embodiments, the number of the target holes 21 of the fixture plate 2 is not limited.
[0029] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
