Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the application.

[0024] like Figs. 1-3 As shown, the circuit board digital one-time molding system includes a device body 1, a crossbeam 2 installed at one end of the top surface of the device body 1, a spraying platform 3 set on the top of the device body 1, a circuit board placed on the top surface of the spraying platform 3, and a Teflon coating sprayed on the surface of the spraying platform 3. A spraying head 4 is installed in the middle of the side of the crossbeam 2, and the spraying platform 3 is set on top of the spraying head 4. The spraying head 4 performs character layer spraying, solder mask spraying, epoxy resin layer spraying, and circuit layer spraying operations on the top surface of the spraying platform 3. An X-axis drive table 5 and a Y-axis drive table 6 are arranged crosswise on the top surface of the device body 1, and the X-axis drive table 5 is set on top of the Y-axis drive table 6. The spraying platform 3 is installed in the middle of the top surface of the X-axis drive table 5. The Y-axis drive table 6 supports the X-axis drive table 5 by magnetic force. The X-axis drive table 5 is used to move horizontally along the top surface of the device body 1, and the Y-axis drive table 6 is used to move vertically along the top surface of the device body 1.

[0025] During operation, the spraying head 4 can perform character layer spraying, solder mask spraying, epoxy resin layer spraying, and circuit layer spraying on the top surface of the spraying platform 3, forming a circuit board on the top surface of the spraying platform 3. The surface of the spraying platform 3 is coated with Teflon, which facilitates the separation of the circuit board from the spraying platform 3 after it is formed. The spraying head 4 can perform character layer spraying, solder mask spraying, epoxy resin layer spraying, and circuit layer spraying on the spraying platform 3, allowing the circuit board to be formed in one step. Furthermore, the spraying head 4 uses material deposition technology, similar to 3D printing technology, without any material reduction process or the need for drilling through holes, ensuring that the circuit board processing is environmentally friendly and free from solid and dust pollution.

[0026] As one embodiment of the present invention:

[0027] The bottom of the spraying head 4 is equipped with a character layer spraying component 7, which is used to spray pigment onto the top surface of the circuit board to form character symbols on the top surface of the circuit board.

[0028] As one embodiment of the present invention:

[0029] The bottom of the spraying head 4 is equipped with a solder resist spraying assembly 8, which is used to spray green paint onto the top surface of the circuit board.

[0030] As one embodiment of the present invention:

[0031] An epoxy resin layer spraying assembly 9 is installed at the bottom of the spraying head 4. The epoxy resin layer spraying assembly 9 is used to spray an epoxy resin layer onto the top surface of the spraying platform 3 to form a circuit board base layer.

[0032] As one embodiment of the present invention:

[0033] The bottom of the spraying head 4 is equipped with a circuit layer spraying component 10, which is used to spray circuit patterns onto the top surface of the circuit board.

[0034] The circuit pattern is sprayed onto the top surface of the circuit board using the circuit layer spraying component 10. No chemical etching is required during the spraying process, making the production process environmentally friendly and pollution-free.

[0035] Through the cooperation of the character layer spraying component 7, the solder mask layer spraying component 8, the epoxy resin layer spraying component 9, and the circuit layer spraying component 10, the circuit board can be formed in one step without the need for wafer fabrication and board fabrication processes, which greatly reduces the investment in equipment and space, greatly reduces the generation of solid waste and hazardous waste, and the process time for a single circuit board can be shortened to a few hours.

[0036] As one embodiment of the present invention:

[0037] The X-axis drive stage 5 is equipped with an electromagnetic top plate 51. When the electromagnetic top plate 51 is energized, the top surface of the electromagnetic top plate 51 generates an S-pole magnetic force. The Y-axis drive stage 6 is equipped with several electromagnetic bottom plates 61. The electromagnetic bottom plates 61 are evenly distributed in a straight line. An attractive electromagnetic block 62 is provided in the middle of the electromagnetic bottom plate 61, and a repulsive electromagnetic block 63 is provided at both ends of the electromagnetic bottom plate 61. When the attractive electromagnetic block 62 is energized, the top surface of the attractive electromagnetic block 62 generates an N-pole magnetic force, and when the repulsive electromagnetic block 63 is energized, the top surface of the repulsive electromagnetic block 63 generates an S-pole magnetic force. The repulsive force between the two repulsive electromagnetic blocks 63 and the electromagnetic top plate 51 is greater than the attractive force between the attractive electromagnetic block 62 and the electromagnetic top plate 51.

[0038] During operation, the electromagnetic top plate 51 in the X-axis drive stage 5 and the electromagnetic base plate 61 in the Y-axis drive stage 6 can be energized sequentially. After energization, the top surface of the electromagnetic top plate 51 generates an S-pole magnetic force. Since the electromagnetic base plate 61 has an attractive electromagnetic block 62 in the middle and repulsive electromagnetic blocks 63 at both ends, the attractive electromagnetic block 62 generates an N-pole magnetic force on its top surface after energization, and the repulsive electromagnetic block 63 generates an S-pole magnetic force. Therefore, the magnetic poles of the attractive electromagnetic block 62 and the electromagnetic top plate 51 are opposite, generating... The magnetic poles of the electromagnetic blocks 63 and the electromagnetic top plate 51 are the same, generating a repulsive force. Since the repulsive force between the two repulsive electromagnetic blocks 63 and the electromagnetic top plate 51 is greater than the attractive force between the attractive electromagnetic blocks 62 and the electromagnetic top plate 51, the X-axis drive stage 5 can be suspended on the top of the Y-axis drive stage 6. The attractive force generated between the attractive electromagnetic blocks 62 and the electromagnetic top plate 51 can ensure that the X-axis drive stage 5 is stable on the top surface of the Y-axis drive stage 6, and also ensure that the X-axis drive stage 5 moves more smoothly along the direction of the Y-axis drive stage 6.

[0039] The X-axis drive platform 5 and the Y-axis drive platform 6 can be driven by electric push rods, hydraulic push rods, or pneumatic push rods to achieve the lateral movement of the X-axis drive platform 5 along the top surface of the device body 1 and the longitudinal movement of the Y-axis drive platform 6 along the top surface of the device body 1. Since the spraying platform 3 is installed at the center of the top surface of the X-axis drive platform 5, the movement of the X-axis drive platform 5 and the Y-axis drive platform 6 can drive the spraying platform 3, enabling the spraying platform 3 to move laterally and longitudinally along the top surface of the device body 1. This ensures that the spraying head 4 can perform character layer spraying, solder mask layer spraying, epoxy resin layer spraying, and circuit layer spraying operations on the top surface of the spraying platform 3.

[0040] The working principle of this invention is as follows: First, the spraying platform 3 is moved to the bottom surface of the epoxy resin layer spraying assembly 9 by the X-axis drive stage 5 and the Y-axis drive stage 6. The epoxy resin layer spraying assembly 9 is used to spray an epoxy resin layer onto the top surface of the spraying platform 3 to form the circuit board base layer. During this process, the X-axis drive stage 5 and the Y-axis drive stage 6 drive the spraying platform 3 to make the circuit board base layer formed on the top surface of the spraying platform 3 uniform in thickness and shape. Then, the solder resist layer spraying assembly 8 is used to spray green oil onto the top surface of the circuit board base layer. After the green oil solder resist layer is sprayed, the circuit layer spraying assembly 10 is used to spray circuit patterns onto the top surface of the circuit board. Finally, the character layer spraying assembly 7 is used to spray pigment onto the top surface of the circuit board to form character symbols on the top surface of the circuit board, thus completing the production of the circuit board.

[0041] During operation, the electromagnetic top plate 51 in the X-axis drive stage 5 and the electromagnetic base plate 61 in the Y-axis drive stage 6 can be energized sequentially. After energization, the top surface of the electromagnetic top plate 51 generates an S-pole magnetic force. Since the electromagnetic base plate 61 has an attractive electromagnetic block 62 in the middle and repulsive electromagnetic blocks 63 at both ends, the attractive electromagnetic block 62 generates an N-pole magnetic force on its top surface after energization, and the repulsive electromagnetic block 63 generates an S-pole magnetic force. Therefore, the magnetic poles of the attractive electromagnetic block 62 and the electromagnetic top plate 51 are opposite, generating... The magnetic poles of the electromagnetic blocks 63 and the electromagnetic top plate 51 are the same, generating a repulsive force. Since the repulsive force between the two repulsive electromagnetic blocks 63 and the electromagnetic top plate 51 is greater than the attractive force between the attractive electromagnetic blocks 62 and the electromagnetic top plate 51, the X-axis drive stage 5 can be suspended on the top of the Y-axis drive stage 6. The attractive force generated between the attractive electromagnetic blocks 62 and the electromagnetic top plate 51 can ensure that the X-axis drive stage 5 is stable on the top surface of the Y-axis drive stage 6, and also ensure that the X-axis drive stage 5 moves more smoothly along the direction of the Y-axis drive stage 6.

[0042] The X-axis drive platform 5 and the Y-axis drive platform 6 can be driven by electric push rods, hydraulic push rods, or pneumatic push rods to achieve the lateral movement of the X-axis drive platform 5 along the top surface of the device body 1 and the longitudinal movement of the Y-axis drive platform 6 along the top surface of the device body 1. Since the spraying platform 3 is installed at the center of the top surface of the X-axis drive platform 5, the movement of the X-axis drive platform 5 and the Y-axis drive platform 6 can drive the spraying platform 3, enabling the spraying platform 3 to move laterally and longitudinally along the top surface of the device body 1. This ensures that the spraying head 4 can perform character layer spraying, solder mask layer spraying, epoxy resin layer spraying, and circuit layer spraying operations on the top surface of the spraying platform 3.

[0043] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
