However, traditional FPC circuit board printing equipment is gradually unable to meet the growing production needs and high-precision requirements. In terms of material transportation, the lack of effective tension control and material sorting devices often leads to wrinkles, offsets and even tears in the circuit board raw materials and printed inner boards during transportation, seriously affecting the printing quality and production efficiency. In the printing process, the inkjet system of traditional equipment is not accurate enough, and it is difficult to achieve accurate printing of tiny circuits and complex patterns. The ink volume control is unstable, and it is easy to have too much or too little ink, resulting in defects such as short circuits or open circuits;

Furthermore, the equipment's stability and reliability are insufficient, and components are prone to wear and loosening after long periods of operation. This leads to frequent equipment failures, high maintenance costs, and prolonged downtime, impacting production schedules and business profitability. Utility Model Content

[0019] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Example 1
[0021] like Figure 1-4 As shown, an FPC circuit board printing device is provided, including a base 1, a fixed cavity 2 is fixedly connected to the left side of the upper surface of the base 1, a side cover 3 is fixedly connected to the right side of the fixed cavity 2, a motor 4 is fixedly connected to the left side of the interior of the fixed cavity 2, a transmission column 5 is fixedly connected to the right side of the output end of the motor 4, the right side of the transmission column 5 passes through the right side of the side cover 3, the outer wall of the transmission column 5 is fixedly connected to the right side of the side cover 3, a cylinder 6 is fixedly connected to the outer wall of the cylinder 6, a circuit board raw material 7 is wound around the outer wall of the cylinder 6, a transport cavity 8 is provided on the rear surface of the base 1, a feed port 9 is opened on the front surface of the transport cavity 8, a rotating rod 10 is fixedly connected to the left side of the inner wall of the fixed cavity 2, and the output end of the rotating rod 10 The right end passes through the right side of the side cover 3, the outer wall of the rotating rod 10 is fixedly connected to the raw material cylinder 11, and the outer wall of the raw material cylinder 11 is wound with a printing inner plate 12. On the right side of the side cover 3, an inkjet device 13 is fixedly connected to the upper surface of the rotating rod 10. On the right side of the side cover 3, an extrusion rod 14 is fixedly connected below the cylinder 6, and an extrusion rod 2 15 is fixedly connected to the lower surface of the extrusion rod 14. The printing inner plate 12 contacts the outer walls of the inkjet device 13, the extrusion rod 14 and the extrusion rod 2, and extends to the inside of the feed port 9. A transmission belt 22 is wound inside the fixed cavity 2 between the outer wall of the transmission column 5 and the outer wall 10 of the rotating rod 10.
[0022] Before motor 4 starts, the circuit board raw material 7 is wound around cylinder 6, and the printed inner plate 12 is wound around the raw material barrel 11. All components are initially stationary, ready for printing. The main function of the transmission belt 22 is to transmit power between the transmission column 5 and the rotating rod 10. When motor 4 starts, its output end drives the transmission column 5 to rotate. The rotational power of the transmission column 5 is transmitted to the rotating rod 10 via the transmission belt 22 wound between its outer wall and the outer wall of the rotating rod 10. In this way, the rotating rod 10 can rotate synchronously with the drive column 5, thereby driving the raw material barrel 11 to which it is fixed, achieving the orderly release of the printed inner plate 12 from the raw material barrel 11 and providing the basic conditions for subsequent printing, extrusion, and other processes. The output end drives the rotation of the transmission column 5. The transmission column 5 extends from the interior of the fixed chamber 2 to the right through the side cover 3. As the transmission column 5 rotates, the cylinder 6 fixed to its outer wall on the right side of the side cover 3 rotates synchronously. As cylinder 6 rotates, the circuit board stock 7 wrapped around its outer wall begins to release, providing underlying support and other related functions for the subsequent processing of the printed inner board 12. The rotating rod 10 drives the release of the printed inner board: Simultaneously, the rotating rod 10, fixed to the left inner wall of the fixed chamber 2, rotates under the action of power. The right end of the rotating rod 10 extends through the side cover 3. The raw material barrel 11, fixed to its outer wall, rotates with the rotation of the rotating rod 10, thereby releasing the printed inner board 12 wrapped around the outer wall of the raw material barrel 11. During the release of the printed inner board 12, the inkjet device 13 located on the upper surface of the rotating rod 10 on the right side of the side cover 3 begins to operate. The inkjet device 13 sprays printing material such as ink onto the moving surface of the printed inner board 12 according to a preset program and pattern, printing the circuit pattern. After printing, the printed inner board 12 continues to move, and as it passes by the squeezing rods 14 and 15 located below the cylinder 6, they squeeze the printed inner board 12. This process can make the printing ink adhere better to the printed inner plate 12, and can also flatten the printed inner plate 12 to ensure the printing quality and stability of subsequent processing. After printing and extrusion, the printed inner plate 12 enters the transport cavity 8 through the feed port 9 on the front surface of the transport cavity 8 under the action of its own moving inertia and the possible auxiliary pushing device. In the transport cavity 8, there should be corresponding transportation mechanisms such as conveyor belts, rollers, etc. The article does not describe in detail how to transport the printed inner plate 12 to subsequent processing steps, such as drying, cutting, testing, etc., or transport it to a collection area for centralized processing, thereby completing the printing and preliminary transportation process of the FPC circuit board printed inner plate. Throughout the process, the various components work together to ensure the orderly progress of the printing work.
[0023] In this embodiment, a rotating bottom rod 16 is fixedly connected to the lower right side of the side cover 3, and a contact bottom plate 17 is provided around the outer side wall of the rotating bottom rod 16. A limit rod 18 is fixedly connected to the upper surface of the rotating bottom rod 16 on the right side of the side cover 3. The outer side wall of the contact bottom plate 17 contacts the limit rod 18, and the top end of the contact bottom plate 17 extends to the inside of the feed port 9.
[0024] After the printed inner plate 12 is printed by the inkjet device 13 and then squeezed by the squeezing rod 14 and the squeezing rod 2 15, it continues to move forward and prepares to enter the feed port 9. At this time, the contact bottom plate 17 plays a role of receiving and guiding. Since the top of the contact bottom plate 17 extends to the inside of the feed port 9, it can ensure that the printed inner plate 12 and other components can be relatively smoothly transitioned from the previous processing area to the feed port 9 and then into the transport cavity 8. The existence of the limit rod 18 plays a role of limiting the contact bottom plate 17. It limits the rotation range of the contact bottom plate 17 on the rotating bottom rod 16, so that the contact bottom plate 17 can maintain a suitable position and angle when receiving and guiding the printed inner plate 12 and other components, ensuring the smoothness of the entire transition process, and avoiding the contact bottom plate 17 from being unable to accurately receive or guide the printed inner plate 12 to enter the feed port 9 due to excessive rotation and other reasons.
[0025] In this embodiment, the inkjet device 13 includes a horizontal block 101. The outer wall of the horizontal block 101 is symmetrically fixedly connected to a connecting rod 102. The outer wall of the connecting rod 102 is rotatably connected to a sleeve 103. The upper surface of the horizontal block 101 is fixedly connected to a fixed block 104. The outer wall of the fixed block 104 is symmetrically fixedly connected to a connecting plate 105. The opposite side of the connecting plate 105 is symmetrically rotatably connected to a printing roller 106. The outer wall of the printing roller 106 is provided with a laser dot inkjet hole 107. The printing inner plate 12 contacts the inner side of the laser dot inkjet hole 107.
[0026] When the printing plate 12 moves within the machine to the location of the inkjet device 13, it comes into contact with the inner side of the laser dot inkjet apertures 107 on the outer wall of the print roller 106. At this point, the ink supply system within the inkjet device 13 precisely sprays ink onto the surface of the printing plate 12 through the laser dot inkjet apertures 107. The rotational connection between the print roller 106 and the connecting plate 105 allows it to adapt to the movement speed and surface conditions of the printing plate 12. During the printing process, the printing roller 106 can rotate accordingly according to the movement of the printing inner plate 12, ensuring that the laser point inkjet hole 107 always maintains a good contact state with the printing inner plate 12, thereby achieving uniform and accurate inkjet printing. At the same time, the horizontal block 101 is connected to the outer sleeve 103 through the rotation of the connecting rod 102, and the coordinated action of components such as the fixed block 104 ensures the stability and flexibility of the entire inkjet device 13 during the operation of the equipment, so that it can meet the printing needs while adapting to various possible equipment operating conditions and changes in the characteristics of the printing inner plate 12.
[0027] In this embodiment, a plurality of support bases 19 are symmetrically fixedly connected to the lower surface of the base 1;
[0028] Multiple support brackets 19 are symmetrically fixed to the lower surface of base 1. This symmetrical layout helps evenly distribute the weight of the device, ensuring that the device remains balanced and stable when placed. Each support bracket 19 is firmly connected to base 1, perhaps through welding, bolting, or other reliable fixing methods, ensuring that the support brackets 19 will not easily loosen or fall off during operation, thereby providing continuous and reliable support for the device.
[0029] In this embodiment, a plurality of separation rollers 20 are fixedly connected to the right side of the side cover 3;
[0030] During the release process, the circuit board raw material 7 may become attached to impurities in the surrounding environment or loose parts generated during the winding process. The separation roller 20 can also properly sort and separate the circuit board raw material 7, ensuring that the circuit board raw material 7 can smoothly provide support for the printed inner board 12 and other related functions, and that the circuit board raw material 7 is in good condition and does not affect the operation of the entire equipment.
[0031] In this embodiment, a control switch 21 is fixedly connected to the front surface of the fixed cavity 2 .
[0032] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
