Description

Technical Field

[0001] This utility model belongs to the field of integrated circuit board manufacturing technology, specifically relating to a drilling machine used in integrated circuit board manufacturing. Background Technology

[0002] Integrated circuit boards are manufactured using semiconductor processes. Many transistors, resistors, capacitors, and other components are fabricated on a small single-crystal silicon wafer. These components are then assembled into complete electronic circuits using multilayer or tunnel wiring methods. The production process involves material preparation, drilling, copper plating, lamination, exposure, development, copper plating, soldering, film removal, etching, solder removal, optical inspection, solder resist application, and solder resist exposure. Therefore, after etching, a drilling machine is needed to drill through the holes in the board to allow for the insertion of electrical components and their subsequent soldering, resulting in a more secure assembly between the electronic components and the circuit board. This process involves drilling.

[0003] Chinese patent discloses a drilling machine for integrated circuit board production (publication number CN219287835U). The moving component of this utility model can change the orientation of the circuit board by rotation, so that the drilling head can perform four processing operations on the same point without moving the upper path of each group of circuit boards. It does not require changing the moving path. At the same point, only the upper and lower positions of the drilling head need to be changed for processing, thereby reducing the length of the moving path inside the equipment, reducing the mechanical wear of the equipment drive components, and improving the service life of the equipment.

[0004] When drilling holes in a circuit board, the drilling process generates debris. Because the debris is small, some of it adheres to the surface of the circuit board. It is not easy for the debris to fall off when the circuit board is adjusted by the rotating wheel. At the same time, the debris may adhere to the surface of the circuit board, affecting subsequent electroplating, soldering and other processes, thereby reducing the electrical performance of the circuit board.

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-4 As shown, a drilling machine for integrated circuit board production includes a base 1, a drill 3, a driver 5, and a positioner 10. A control board 2 is fixedly connected to the surface of the base 1, and four placement racks 4 are fixedly connected to the surface of the base 1. Rotating wheels 6 are rotatably connected to the inner walls of the four placement racks 4, and four mounting racks 7 are fixedly connected to the inner walls of the rotating wheels 6. A collecting device 8 is provided on the surface of the base 1, and an auxiliary device 9 is provided on the surface of the base 1.

[0025] In this embodiment of the utility model: the circuit board that needs to be drilled is installed on the mounting bracket 7, and then the drill 3 is adjusted to the appropriate position to start the drilling operation. During the adjustment process, the auxiliary device 9 can help to accurately position and unify the drilling position. Furthermore, the drive 5 drives the rotating wheel 6 to rotate, which can realize the replacement of the circuit board. During the replacement process, the circuit board can come into contact with the collection device 8 to achieve the collection of debris.

[0026] like Figure 1-3 As shown, the collecting device 8 includes two sliding plates 801, both of which are slidably connected to the surface of the base 1. A vertical rod 802 is fixedly connected to the surface of each sliding plate 801. An extension rod 803 is fixedly connected to the end of each vertical rod 802 away from the sliding plate 801. A cylinder 804 is rotatably connected to the arc surface of the extension rod 803. An external rod 811 is fixedly connected to the arc surface of the cylinder 804. The external rod 811 is T-shaped, and two square rods 812 are fixedly connected to the surface of the external rod 811. Connecting cylinders 81 are slidably connected to the surfaces of the two square rods 812. 3. A rotating ring 814 is rotatably connected to the surface of the connecting cylinder 813. A conveyor belt 815 is driven to the surface of the rotating ring 814. An adhesive layer 816, made of silicone, is bonded to the surface of the conveyor belt 815. By installing the conveyor belt 815 and the adhesive layer 816, debris falling from the circuit board due to the rotation of the drive wheel after drilling can be collected. The adhesive layer 816 can also contact the surface of the circuit board to adhere and clean the debris. A torsion spring 807 is fitted onto the surface of the extension rod 803. Both ends are fixedly connected to the cylinder 804 and the upright 802 respectively. The torsion spring 807 helps the cylinder 804 to be positioned, thus facilitating the replacement of the adhesive layer 816 on the surface of the conveyor belt 815. An extension plate 805 is fixedly connected to the arc surface of the cylinder 804. A circular hole 806 is opened on the surface of the extension plate 805. When the operator needs to rotate the cylinder 804 to replace the adhesive layer 816, the operator can place his finger in the circular hole 806 to help the cylinder 804 rotate. The circular hole 806 can also... It provides a simple anti-slip effect and increases the convenience of replacing the adhesive layer 816. The end of the extension rod 803 away from the upright rod 802 is fixedly connected to the connecting plate 808. The side of the connecting plate 808 near the rotating wheel 6 is fixedly connected to the roller 809. The surface of the roller 809 is glued with a sponge sleeve 810. Some debris is attached tightly, and the simple contact of the adhesive layer 816 cannot achieve a good cleaning effect. Since the sponge sleeve 810 is made of soft material and the sponge itself has a porous structure, it can contact the debris on the surface of the circuit board and scrape the debris off.

[0027] The working principle described above is as follows: A finger is placed above or below the circular hole 806 in the extension plate 805, causing the slide plate 801 to slide outwards. This, in turn, causes the cylinder 804 to rotate via the extension plate 805. This rotates the connecting frame to an outward position, allowing the operator to slide and install the connecting cylinder 813 on the surface of the square rod 812. The conveyor belt 815 is then installed via the rotating ring 814 on the surface of the connecting cylinder 813. Once the parts are installed, the operator releases their finger, at which point the cylinder 804 is driven by the torsion spring 807. Now, the device is reset so that the adhesive layer 816 on the surface of the conveyor belt 815 can easily come into contact with the accessible part of the circuit board. At this time, the installation of the collection device 8 is completed. When the rotating wheel 6 drives the circuit board to be replaced, the falling debris will stick to the surface of the adhesive layer 816. Because the adhesive layer 816 has easy contact with the surface of the circuit board, it can achieve the effect of easy adhesion and cleaning. When the circuit board is replaced and adjusted, it will come into contact with the sponge sleeve 810. The debris scraped off by the sponge sleeve 810 will also fall to the surface of the adhesive layer 816 for collection.

[0028] like Figure 2 and Figure 4 As shown, the auxiliary device 9 includes a mounting plate 901, which is slidably connected to the output end of the drill 3. Two connecting rods 903 are fixedly connected to the surface of the mounting plate 901. A connecting frame 904 is fixedly connected to the end of the two connecting rods 903 away from the mounting plate 901. A slide rod 905 is slidably connected to the inner wall of the connecting frame 904. A long plate 907 is fixedly connected to the surface of the base 1. Several scale holes 908 are opened on the surface of the long plate 907. The scale holes 908 are linearly arrayed on the surface of the long plate 907. When the drill 3 is adjusting to drill the surface of the circuit board, it can cooperate with the slide rod 905 and the scale groove for auxiliary positioning, helping the drill 3 to drill more accurately on the surface of the circuit board. To achieve precise positioning during drilling, minimal adjustments by the operator are required. An anti-slip ring 902 is glued to the inner wall of the mounting plate 901 and slidably connects to the output end of the drill 3. Made of rubber, the anti-slip ring 902 increases the stability of the mounting plate 901 at the output end of the drill 3, allowing the drill 3 to work well with the slide rod 905 for drilling position calculation and adjustment. A roller 906 is rotatably connected to the end of the slide rod 905 near the long plate 907, and slidably connects to the long plate 907. The roller 906 helps the slide rod 905 slide left and right within the graduated hole 908, preventing positional shift when the drill 3 performs drilling operations to either side.

[0029] The working principle described above is as follows: Before drilling, the operator can slide the mounting plate 901 onto the output end surface of the drill 3. The inner wall of the mounting plate 901 has an anti-slip ring 902, which increases the friction between the mounting plate 901 and the surface of the drill 3. This allows the operator to release the limiting position of the drill 3. Simultaneously, when adjusting the position of the drill 3, the sliding rod 905 slides on the surface of the long plate 907. By observing the scale hole 908 on the surface of the long plate 907, the operator can understand and record the adjustment distance, facilitating subsequent positioning and drilling. Furthermore, the roller 906 is located inside the scale hole 908, ensuring that its position does not shift during left and right adjustments, further facilitating drilling position adjustment on a straight line.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
