Description

Technical Field

[0001] The utility model relates to the field of production and processing of FPC circuit boards, in particular to a hollowing and engraving device for an FPC circuit board. Background Art

[0002] FPC circuit board is a kind of printed circuit board made of polyimide or polyester film with high reliability and excellent flexibility. It has the characteristics of light weight, thin thickness, good bending performance and high wiring density. Therefore, it is widely used in various electronic products.

[0003] The processing principle of FPC circuit boards is mainly based on the microscopic synergy of conductive materials and insulating substrates. Conductive materials (such as copper foil) constitute the circuit pattern of FPC and are responsible for transmitting current and signals; while the insulating substrate (such as polyimide or polyester film) plays the role of supporting and protecting the circuit, ensuring that the current is stably transmitted along a specific path. Through precise processing techniques such as photolithography, etching, electroplating, etc., the circuit pattern is accurately transferred to the insulating substrate to form an FPC finished product with specific functions.

[0004] Existing FPC circuit board hollowing engraving devices generally use a drill bit to directly engrave the circuit board. During use and observation, it was found that this processing method will generate a large amount of debris during the processing. These debris remaining on the circuit board will not only affect the drill bit's processing of the circuit board, but also cause scratches on the surface of the circuit board, causing damage to the circuit board.

[0005] Therefore, in order to solve the above problems, an FPC circuit board hollowing engraving device is proposed. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the FPC circuit board hollow engraving device described in the present invention includes an operating table; a group of first linear motors are fixedly connected to the top of the operating table; the output end of the first linear motor is fixedly connected to a support column; a second linear motor is fixedly connected between the support columns; the output end of the second linear motor is fixedly connected to a connecting column; the end of the connecting column is fixedly connected to an engraving component; a connecting plate is fixedly connected to the middle of the connecting column; an exhaust pipe is provided through the middle of the connecting plate; the end of the exhaust pipe is connected to an exhaust box; by providing an exhaust pipe through the middle of the connecting plate and connecting the exhaust box at the end of the exhaust pipe, the debris generated by the engraving can be adsorbed when the engraving component engraves the circuit board, thereby reducing the situation where the debris generated by the engraving stays on the surface of the circuit board and causes scratches on the circuit board.

[0008] Preferably, the end of the connecting plate is slidably connected to a baffle; the baffle is correspondingly arranged, and by slidably connecting a pair of baffles at the end of the connecting plate, the adsorption space can be reduced when the vacuum box adsorbs debris, thereby enhancing the vacuum box's adsorption effect on debris generated during engraving.

[0009] Preferably, a plurality of first brackets are fixed to the bottom of the baffle; a ball is rotatably connected to the end of the first bracket. By rotatably connecting the ball to the end of the first bracket, the ball can press down and fix the circuit board when the engraving component engraves the circuit board, thereby reducing the shaking of the circuit board during the engraving process.

[0010] Preferably, a pair of second brackets are fixedly connected to the middle of the connecting column; an air pipe is fixedly connected to the end of the second bracket. By fixing the air pipe to the end of the second bracket, cold air can be delivered to the surface of the circuit board when the engraving component is engraving the circuit board, which can reduce the deformation and damage of the circuit board caused by excessive heat generated during the engraving process.

[0011] Preferably, the end of the gas pipe is connected to a fan-shaped nozzle; the fan-shaped nozzle is a trumpet-shaped structure. After the cold air is transported into the gas pipe, the cold air is blown toward the surface of the circuit board through the fan-shaped nozzle. By connecting the fan-shaped nozzle to the end of the gas pipe, the cold air blown toward the surface of the circuit board can be diffused when the cold air is injected into the gas pipe, thereby increasing the contact area between the cold air and the circuit board and achieving a better cooling effect.

[0012] Preferably, a panel is fixedly connected to the top of the operating table; the first linear motor is located inside the panel, and the debris generated when the engraving component engraves the circuit board is adsorbed by the vacuum box, and the small amount of remaining debris still remains on the surface of the operating table. By fixing the panel on the operating table, the small amount of remaining debris can be blocked, reducing the pollution of the operating environment caused by the splashing of debris. At the same time, by providing the panel, the influence of external dust and impurities on the engraving of the circuit board can be reduced when the engraving component engraves the circuit board.

[0014] 1. The FPC circuit board hollowing engraving device described in the utility model has an exhaust pipe running through the middle of the connecting plate, and an exhaust box is connected to the end of the exhaust pipe. When the engraving component is engraving the circuit board, the engraving debris is absorbed, thereby reducing the situation where the engraving debris stays on the surface of the circuit board and causes scratches on the circuit board.

[0015] 2. The FPC circuit board hollowing engraving device described in the utility model is capable of reducing the adsorption space when the vacuum box adsorbs debris by slidingly connecting a pair of baffles at the end of the connecting plate, thereby enhancing the vacuum box's adsorption effect on debris generated during engraving.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] like Figures 1 to 5As shown, an FPC circuit board hollowing engraving device described in an embodiment of the present invention includes an operating table 1; a group of first linear motors 11 are fixedly connected to the top of the operating table 1; the output end of the first linear motor 11 is fixedly connected to a support column 12; a second linear motor 13 is fixedly connected between the support columns 12; the output end of the second linear motor 13 is fixedly connected to a connecting column 14; the end of the connecting column 14 is fixedly connected to an engraving component 15; a connecting plate 16 is fixedly connected to the middle of the connecting column 14; an exhaust pipe 17 is provided through the middle of the connecting plate 16; the end of the exhaust pipe 17 is connected to an exhaust box 18; when working, the circuit board is placed on the top of the operating table 1 and then the first linear motor 11 is turned on. When the first linear motor 11 moves, it drives the The support column 12 moves, and when the first linear motor 11 moves to the specified position, the second linear motor 13 is turned on. The movement of the second linear motor 13 drives the engraving component 15 fixed to the end of the connecting column 14 to move. The rotating engraving component 15 engraves the circuit board. When the engraving component 15 engraves the circuit board, an exhaust device is connected to the end of the exhaust pipe 17. When the engraving component 15 engraves the circuit board, debris generated is extracted through the exhaust box 18. By providing an exhaust pipe 17 through the middle of the connecting plate 16 and connecting the exhaust box 18 to the end of the exhaust pipe 17, the debris generated by the engraving can be adsorbed when the engraving component 15 engraves the circuit board, thereby reducing the situation where the debris generated by the engraving stays on the surface of the circuit board and causes scratches on the circuit board.

[0026] like Figure 2 As shown, the end of the connecting plate 16 is slidably connected to a baffle 2; the baffle 2 is correspondingly arranged, and when the engraving component 15 engraves the circuit board, the debris generated is adsorbed by the vacuum box 18. At this time, the baffle 2 reduces the adsorption space of the vacuum box 18. By slidingly connecting a pair of baffles 2 to the end of the connecting plate 16, the adsorption space can be reduced when the vacuum box 18 adsorbs the debris, thereby enhancing the adsorption effect of the vacuum box 18 on the debris generated during engraving.

[0027] like Figure 3 As shown, a plurality of first brackets 3 are fixedly connected to the bottom of the baffle 2; a ball 31 is rotatably connected to the end of the first bracket 3. When the second linear motor 13 drives the connecting column 14 to move to the specified position and the engraving component 15 engraves the circuit board, the ball 31 contacts the surface of the circuit board and rolls on the surface of the circuit board during the engraving process. When the ball 31 contacts the circuit board, the circuit board is pressed down. By rotatably connecting the ball 31 to the end of the first bracket 3, the ball 31 can press down and fix the circuit board when the engraving component 15 engraves the circuit board, thereby reducing the shaking of the circuit board during the engraving process.

[0028] like Figure 4As shown, a pair of second brackets 4 are fixedly connected to the middle of the connecting column 14; an air pipe 41 is fixedly connected to the end of the second bracket 4. When the engraving component 15 engraves the circuit board, cold air is injected into the air pipe 41, and the cold air is blown to the surface of the circuit board through the air pipe 41. By fixing the air pipe 41 to the end of the second bracket 4, the cold air can be transported to the surface of the circuit board when the engraving component 15 engraves the circuit board, which can reduce the deformation and damage of the circuit board caused by excessive heat generated during the engraving process.

[0029] like Figure 5 As shown, the end of the air pipe 41 is connected to a fan-shaped nozzle 5; the fan-shaped nozzle 5 is a trumpet-shaped structure. After the cold air is transported into the air pipe 41, the cold air is blown toward the surface of the circuit board through the fan-shaped nozzle 5. By connecting the fan-shaped nozzle 5 at the end of the air pipe 41, the cold air blown toward the surface of the circuit board can be diffused when the cold air is injected into the air pipe 41, thereby increasing the contact area between the cold air and the circuit board and achieving a better cooling effect.

[0030] like Figure 5 As shown, a panel 6 is fixedly connected to the top of the operating table 1; the first linear motor 11 is located inside the panel 6. When the engraving component 15 engraves the circuit board, the debris generated is adsorbed by the vacuum box 18, and the small amount of remaining debris still remains on the surface of the operating table 1. By fixing the panel 6 on the operating table 1, the small amount of remaining debris can be blocked to reduce the pollution of the operating environment caused by the splashing of debris. At the same time, by providing the panel 6, the influence of external dust and impurities on the circuit board engraving can be reduced when the engraving component 15 engraves the circuit board.

[0031] Working principle: Place the circuit board on top of the operating table 1 and then turn on the first linear motor 11. When the first linear motor 11 moves, it drives the support column 12 fixed to its output end to move. When the first linear motor 11 moves to the specified position, the second linear motor 13 is turned on. While the second linear motor 13 moves, it drives the engraving component 15 fixed to the end of the connecting column 14 to move. The rotating engraving component 15 engraves the circuit board. When the engraving component 15 engraves the circuit board, an exhaust device is connected to the end of the exhaust pipe 17. When the engraving component 15 engraves the circuit board, the debris generated is extracted through the exhaust box 18. When the engraving assembly 15 engraves the circuit board, the debris generated is adsorbed by the vacuum box 18. At this time, the baffle 2 reduces the adsorption space of the vacuum box 18. A pair of baffles 2 are slidably connected to the end of the connecting plate 16, which can reduce the adsorption space when the vacuum box 18 adsorbs the debris, thereby enhancing the adsorption effect of the vacuum box 18 on the debris generated during engraving. When the second linear motor 13 drives the connecting column 14 to move to the specified position, the engraving assembly 15 engraves the circuit board, and the ball 31 contacts the surface of the circuit board and rolls on the surface of the circuit board during the engraving process. When the ball 31 contacts the circuit board When the circuit board is pressed down, the ball 31 is connected to the end of the first bracket 3 by rotation, so that the ball 31 can press the circuit board down and fix it when the engraving component 15 is engraving the circuit board. When the engraving component 15 is engraving the circuit board, cold air is injected into the air pipe 41, and the cold air is blown to the surface of the circuit board through the air pipe 41. By fixing the air pipe 41 at the end of the second bracket 4, the cold air can be delivered to the surface of the circuit board when the engraving component 15 is engraving the circuit board. After the cold air is delivered to the inside of the air pipe 41, the cold air is blown to the surface of the circuit board through the fan-shaped nozzle 5. There is a fan-shaped nozzle 5, which can diffuse the cold air blown onto the surface of the circuit board when injecting cold air into the air pipe 41, thereby increasing the contact area between the cold air and the circuit board. The debris generated when the engraving component 15 engraves the circuit board is adsorbed by the vacuum box 18, and the small amount of remaining debris still remains on the surface of the operating table 1. By fixing the enclosure 6 on the operating table 1, the small amount of remaining debris can be blocked to reduce the pollution of the operating environment caused by the splashing of debris. At the same time, the provision of the enclosure 6 can reduce the impact of external dust and impurities on the engraving of the circuit board when the engraving component 15 engraves the circuit board.
