Abstract
Description
Technical Field
[0001] The utility model relates to the field of PCB circuit board manufacturing, in particular to a device for punching holes at equal distances on a PCB circuit board. Background Art
[0002] PCB is a printed circuit board, which is a basic component used in electronic devices. PCB is a method of making circuit connections by printing circuit patterns and component layouts on an insulating substrate. In the production process of PCB, it is usually necessary to punch holes on the substrate, including mounting holes, connecting holes, long through holes, etc. The mounting holes are used to position or support the PCB; the connecting holes are used to connect the electrical connection points of different layers on the PCB; the long through holes are used to connect the electrical connection points of two panels on the PCB.
[0003] In order to obtain holes arranged at equal intervals, an equidistant drilling method is usually used so that a group of equally spaced holes are formed synchronously. The equidistant drilling equipment in the prior art usually uses a cylinder or a ball screw to adjust the spacing, and mechanical drilling or laser drilling is performed after the required spacing is obtained. However, after adjusting to the required spacing, the position of the drilling device is often not fixed. Therefore, if vibration or other interference occurs during the drilling process, it is easy to cause the drill or laser to have difficulty drilling along the same axis, affecting the drilling accuracy.

[0035] The following is further described in detail through specific implementation methods:
[0036] Implementation example Figure 1 As shown: a device for equidistantly punching holes on a PCB circuit board, comprising an operating table 1 and a controller. The operating table 1 of this embodiment is provided with an operating area for punching holes. The controller uses an integrated human-computer interaction interface 6, and the human-computer interaction interface 6 is fixedly mounted on the side wall of the operating table 1, so that the operator can perform corresponding operations thereon according to needs.
[0037] The operating table 1 is provided with a position adjustment component, and the position adjustment component is provided with a connecting plate 5. Specifically, the position adjustment component includes two Y-axis slide rails 3 and one X-axis slide rail 4, and both the Y-axis slide rail 3 and the X-axis slide rail 4 are controlled by a servo motor 2, and the servo motor 2 is installed at one end of the Y-axis slide rail 3 and the X-axis slide rail 4, and the servo motors 2 of the Y-axis slide rail 3 and the X-axis slide rail 4 are connected to the human-machine interaction interface 6 signal.
[0038] Two Y-axis slide rails 3 are symmetrically fixedly connected to both sides of the top surface of the operating table 1, and the X-axis slide rail 4 is mounted on the slide seats of the two Y-axis slide rails 3. The connecting plate 5 is fixedly connected to the slide seat of the X-axis slide rail 4. The servo motors 2 of the two Y-axis slide rails 3 are controlled to run synchronously through the human-machine interaction interface 6, that is, the movement of the punching position on the Y axis can be realized, and the servo motor 2 of the X-axis slide rail 4 is controlled to run through the human-machine interaction interface 6, that is, the movement of the punching position on the X axis can be realized, so that the punching position covers the entire operating area on the operating table 1.
[0039] Combined with Figure 2-6 As shown, three sliding grooves 11 are provided on the connecting plate 5, and the sliding grooves 11 are arranged along the length direction of the connecting plate 5. A sliding shaft 19 is slidably connected in each sliding groove 11, and a magnetic metal belt 17 is bonded and fixed at the bottom of the sliding groove 11. The magnetic metal belt 17 is made of magnetic materials such as iron, cobalt, and nickel.

[0040] In addition, both ends of the connecting plate 5 are fixedly connected to the limit plates 12, and the sliding groove 11 is located between the two limit plates 12. The limit plates 12 limit the maximum sliding stroke of the sliding shaft 19 to prevent the sliding shaft 19 from being separated from the sliding groove 11.
[0041] The sliding shaft 19 on the same vertical line is fixedly connected to a mounting seat 9 at one end away from the sliding groove 11. A punching member 10 is fixedly connected to the mounting seat 9. The punching member 10 can be selected according to the actual PCB circuit board production requirements.

A vertical first guide groove 14 is provided in the center of the guide plate 13, and four inclined second guide grooves 15 are provided on both sides of the guide plate 13.

The guide wheels 16 of the middle mounting seat 9 are slidably matched with the first guide groove 14, and the guide wheels 16 of the mounting seats 9 on both sides are slidably matched with the corresponding second guide grooves 15. In order to reduce the impact vibration generated when the guide wheels 16 contact the two ends of the first guide groove 14 and the second guide groove 15, buffer pads are bonded and fixed at both ends of the first guide groove 14 and the second guide groove 15.
[0044] The specific implementation process is as follows: first, place the PCB circuit board that needs to be drilled into the operating area of the operating table 1; then, set the drilling position and the drilling hole spacing through the human-machine interaction interface 6, and the Y-axis slide 3 and the X-axis slide 4 are operated to adjust the drilling position, and at the same time, the cylinder 7 is operated to adjust the drilling spacing; then, the human-machine interaction interface 6 controls the electromagnet 18 to energize, so that the position of the punching member 10 is locked; finally, the human-machine interaction interface 6 controls the punching member 10 to operate synchronously, and stably realizes the equidistant drilling of the PCB circuit board.
[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
