Description

Technical Field

[0001] This invention relates to the field of circuit board inkjet printing technology, and in particular to a PCB circuit board production equipment. Background Technology

[0002] During the production of printed circuit boards (PCBs), inkjet printers are used to print markings (such as product information, model numbers, and parameters of relevant electronic components) on their surfaces. During printing, the PCB is placed on the inkjet printer, and the print head moves close to the PCB to spray ink, leaving the markings. After printing, a small amount of ink remains at the nozzle, and this ink drips onto the guide rail below the print head.

[0003] To avoid ink contamination and corrosion of the guide rails, existing inkjet printers are equipped with features such as... Figure 1 The protective structure shown has a take-up roller 21 and an oil-proof cloth 22 wound on the feed side of the inkjet printer. The end of the oil-proof cloth 22 is connected to the support table. When the inkjet printing task is performed, the support table moves and pulls out the oil-proof cloth 22 so that it is laid above the guide rail to block the falling ink.

[0004] The aforementioned protective structure only protects the front of the inkjet printer. The area behind it, uncovered by the tarpaulin 22, is not covered. Ink remaining on the printhead does not fall off immediately; after printing, residual ink at the nozzle gradually accumulates under gravity, eventually forming droplets. If the carrier platform has already reset, the ink will still fall directly onto the guide rail. This means the guide rail remains susceptible to contamination and corrosion. Furthermore, the take-up roller 21 rewinds the tarpaulin 22 during carrier platform reset. Frequent forward and reverse rotation of the take-up roller 21 during printing rapidly shortens its internal reset spring lifespan, resulting in a high failure rate for the take-up roller 21. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a PCB circuit board production equipment that prevents residual ink from contaminating the equipment during the printing process, avoids ink corrosion of the guide rails, and improves the service life of the equipment.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A PCB circuit board manufacturing equipment includes: a barrier strip, a base, a print head located on the front side of the base, and an electric guide rail;

[0008] The electric guide rail is provided with a follower slide, and the follower slide is provided with a first docking part and a second docking part that are symmetrical to each other. One end of the barrier strip is provided on the first docking part, and the other end of the barrier strip passes around the back of the base and is connected to the second docking part.

[0009] Each end of the base is provided with a traction bracket, and each traction bracket is provided with a tension roller, and each tension roller abuts against the barrier belt.

[0010] In one embodiment, the tensioning roller includes a central rod and a plurality of coarse rolling sleeves and a plurality of fine rolling sleeves alternately disposed on the outer wall of the central rod, wherein the outer diameter of the coarse rolling sleeves is larger than the outer diameter of the fine rolling sleeves; the barrier band includes a plurality of secondary barrier bands that abut against the fine rolling sleeves and a plurality of primary barrier bands that abut against the coarse rolling sleeves, wherein the edge of the primary barrier band has an adhesive portion that extends beyond the coarse rolling sleeves and covers the secondary barrier bands adjacent to the primary barrier bands.

[0011] In one embodiment, the length of the coarse rolling sleeve is L1, the length of the fine rolling sleeve is L2, the width of the main isolation strip is H1, and the width of the secondary isolation strip is H2. <L1=L2

[0012] In one embodiment, the coarse rolling sleeve is tactilely connected to the central rod, and the fine rolling sleeve is tactilely connected to the central rod.

[0013] In one embodiment, the traction bracket has a waist-shaped hole at the position where it connects to the base.

[0014] In one embodiment, the base is provided with a cleaning disc.

[0015] In one embodiment, a plurality of auxiliary rollers are provided on the reverse side of the base, and the auxiliary rollers abut against the barrier strip.

[0016] In one embodiment, quick-change components are provided at the locations of the first docking portion and the second docking portion. The quick-change components include a floating bracket, a flip plate, a clamping plate, and a return spring. The floating bracket is slidably disposed on the follower slide. The return spring provides elastic force to keep the floating bracket in close contact with the outer wall of the follower slide. The floating bracket is provided with a limiting pin. The flip plate is rotatably disposed on the follower slide. The flip plate is provided with a locking hole that matches the limiting pin. There is a gap between the flip plate and the floating bracket. The gap is used to accommodate the clamping plate. The clamping plate is provided with a positioning hole that matches the limiting pin. The clamping plate is connected to the end of the barrier strip.

[0017] In one embodiment, the end of the limiting pin is provided with a spherical anti-jamming part.

[0018] ​In one embodiment, the quick-change assembly further includes an auxiliary track, one end of which is disposed on the first docking portion, and the other end of which passes around the back of the base and is connected to the second docking portion. A hook is provided on the outer wall of the auxiliary track, and a T-shaped docking portion matching the hook is provided on the clamping plate.

[0019] The above-mentioned PCB circuit board production equipment has the following advantages:

[0020] 1. Both ends of the barrier strip are connected to the follower slide, allowing the barrier strip to move synchronously with the follower slide. This ensures that the barrier strip can cover the electric guide rail throughout the entire process, blocking any ink drips and improving the equipment's anti-fouling ability.

[0021] 2. The tension roller abuts against the barrier belt, keeping the barrier belt taut, and the sliding process of the barrier belt pulled by the follower slide is stable and smooth.

[0022] 3. The barrier tape can move synchronously with the sliding table, eliminating the need for a dedicated winding component to wind up the barrier tape. This saves on equipment manufacturing costs and avoids maintenance issues caused by winding component failures. Attached Figure Description

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figure 2 The present invention provides a PCB circuit board production equipment 10, including: a barrier strip 100, a base 200, a print head 300 and an electric guide rail 400 located on the front side of the base 200.

[0037] Please see Figure 5 and Figure 6 The electric guide rail 400 is equipped with a follower slide 500, which has a first docking part 510 and a second docking part 520 that are symmetrical to each other. One end of the barrier strip 100 is located on the first docking part 510, and the other end of the barrier strip 100 passes over the opposite side of the base 200 (the side of the base 200 away from the electric guide rail 400) and is connected to the second docking part 520. Figure 5 As shown, the barrier strip 100 and the follower slide 500 together form a "U"-shaped structure, allowing the barrier strip 100 to fully cover the electric guide rail 400.

[0038] For preferred options, please refer to [link / reference]. Figure 5Multiple auxiliary rollers 240 are provided on the reverse side of the base 200. The auxiliary rollers 240 abut against the barrier belt 100, which can reduce the contact area between the barrier belt 100 and the base 200, reduce the resistance when the barrier belt 100 moves, and make its movement smoother.

[0039] Please see Figure 2 and Figure 5 Each end of the base 200 is provided with a traction bracket 210, and each traction bracket 210 is provided with a tension roller 220, each tension roller 220 abutting against the barrier belt 100. Preferably, the traction bracket 210 is provided with an oblong hole at the position where it connects to the base 200. The fixed position of the traction bracket 210 on the base 200 can be adjusted through the oblong hole, thereby adjusting the tension of the barrier belt 100 after it is fixed.

[0040] The system includes a follower slide 500 to support the circuit board to be printed, and an electric guide rail 400 to drive the follower slide 500 to move the circuit board to the position of the print head 300. The print head 300 then performs the printing operation. Specifically, the location of the print head 300 includes a gantry frame, an electric guide rail for adjusting the position of the print head 300, and a CCD image acquisition device. During printing, the CCD captures an image of the circuit board, the electric guide rail moves the print head 300 to the target position, and the print head 300 prints ink onto the circuit board.

[0041] The principle behind the barrier strip 100 preventing residual ink from falling into the motor guide rail 400 is as follows:

[0042] Since the two ends of the barrier strip 100 are connected to the first docking part 510 and the second docking part 520 of the follower slide table 500 respectively, and cooperate with the barrier strip 100 to form a "U"-shaped structure, the barrier strip 100 can cover the first docking part 510 to the front end of the base 200 (product feeding side) and the second docking part 520 to the rear end of the base 200 (side away from the operator), providing all-round protection for the electric guide rail 400.

[0043] When the electric guide rail 400 drives the follower slide 500 from the front end of the base 200 to the position of the print head 300, the first docking part 510 applies a pulling force to the barrier belt 100, pulling the barrier belt 100 towards the front end of the base 200. Figure 5 Taking the state as an example, at this time, the barrier band 100 rotates counterclockwise;

[0044] Conversely, when the electric guide rail 400 drives the follower slide 500 back from the print head 300 to the front end of the base 200, the second docking part 520 applies a pulling force to the barrier belt 100, pulling the barrier belt 100 towards the rear end of the base 200, so as to... Figure 5Taking the current state as an example, the barrier strip 100 rotates clockwise. That is, the electric guide rail 400 drives the follower slide 500 to move, and the barrier strip 100 will rotate accordingly, ensuring that the barrier strip 100 covers the electric guide rail 400 throughout the entire process, which can protect the electric guide rail 400 in all directions.

[0045] In one embodiment, please refer to Figure 2 The base 200 is equipped with a cleaning disc 230. After the print head 300 finishes printing, it can be moved to the cleaning disc 230 for cleaning and removal of any residual ink.

[0046] The PCB circuit board production equipment 10 described above has the following advantages:

[0047] 1. Both ends of the barrier strip 100 are connected to the follower slide 500, so that the barrier strip 100 and the follower slide 500 move synchronously, allowing the barrier strip 100 to cover the electric guide rail 400 throughout the entire process. Whenever ink drips, it will be blocked, thus improving the equipment's anti-fouling ability.

[0048] 2. The tension roller 220 abuts against the barrier belt 100, keeping the barrier belt 100 taut, and the sliding process of the barrier belt 100 pulled by the follower slide table 500 is stable and smooth.

[0049] 3. The barrier tape can move synchronously with the sliding table, eliminating the need for a dedicated winding component to wind up the barrier tape. This saves on equipment manufacturing costs and avoids maintenance issues caused by winding component failures.

[0050] In the PCB circuit board production equipment 10, the two ends of the barrier strip 100 are connected to the follower slide 500, and the two form a "U"-shaped structure, so that the barrier strip 100 rotates when the follower slide 500 moves, protecting the electric guide rail 400 throughout the process and avoiding the influence of residual ink from the printing process on the electric guide rail 400. However, since the entire barrier belt 100 moves with the sliding table 500, the airflow generated during the rotation of the barrier belt 100 is large, and the resistance during the rotation is also large, resulting in noise when the sliding table 500 moves. On the other hand, the sliding table 500 pulls on the barrier belt 100, and since the barrier belt 100 moves as a whole, the pulling force is large, which can easily cause the barrier belt 100 to break during the pulling process. After the barrier belt 100 is broken, its ability to resist the pulling force becomes weaker. If it is not replaced in time, the barrier belt 100 will break at the broken point, and the entire barrier belt 100 will need to be replaced, resulting in high maintenance costs.

[0051] To resolve the above issues, please refer to [link / reference]. Figure 3 and Figure 4The tension roller 220 includes a central rod 221 and a plurality of coarse rolling sleeves 222 and a plurality of fine rolling sleeves 223 alternately disposed on the outer wall of the central rod 221. The coarse rolling sleeves 222 are tactilely connected to the central rod 221, and the fine rolling sleeves 223 are tactilely connected to the central rod 221. The outer diameter of the coarse rolling sleeves 222 is larger than the outer diameter of the fine rolling sleeves 223.

[0052] The barrier band 100 includes a plurality of secondary barrier bands 110 that abut against the fine rolling sleeve 223 and a plurality of main barrier bands 120 that abut against the coarse rolling sleeve 222. The main barrier band 120 has an adhesive portion 121 on its edge, the adhesive portion 121 extends beyond the coarse rolling sleeve 222, and the adhesive portion 121 covers the secondary barrier bands 110 adjacent to the main barrier band 120.

[0053] For further details, please refer to Figure 4 The length of the coarse rolling sleeve 222 is L1, the length of the fine rolling sleeve 223 is L2, the width of the main isolation strip 120 is H1, and the width of the secondary isolation strip 110 is H2. <L1=L2

[0054] It should be noted that you should refer to [link / reference]. Figure 4 The coarse rolling sleeve 222 and the fine rolling sleeve 223 are alternately distributed on the central rod 221, and the outer diameter of the coarse rolling sleeve 222 is larger than the outer diameter of the fine rolling sleeve 223, making the outer side of the central rod 221 continuously concave and convex (protruding at the coarse rolling sleeve 222 and concave at the fine rolling sleeve 223). In addition, the secondary isolation strip 110 contacts the fine rolling sleeve 223, and the main isolation strip 120 contacts the coarse rolling sleeve 222, causing the main isolation strip 120 and the secondary isolation strip 110 to be misaligned. Moreover, the laying position of the main isolation strip 120 is higher than that of the secondary isolation strip 110, resulting in the main isolation strip 120 and the secondary isolation strip 110 being misaligned, and a gap is generated at the junction of the secondary isolation strip 110 and the main isolation strip 120.

[0055] The barrier belt 100 is divided into multiple independent secondary barrier belts 110 and multiple independent main barrier belts 120, with gaps between adjacent secondary barrier belts 110 and main barrier belts 120, reducing the airflow generated during rotation; and the coarse rolling sleeve 222 and fine rolling sleeve 223 in contact with it are both rolledly connected to the central rod 221, reducing the resistance encountered by the barrier belt 100 during rotation, and the vibration generated during rotation is also reduced, which can effectively reduce the noise generated by the barrier belt 100 during rotation.

[0056] ​It is important to note that a crucial objective of this invention is to minimize airflow during the rotation of the barrier strip 100. If the barrier strip 100 is a single, undivided sheet, it generates a very large airflow during rotation, which can interfere with normal text printing on the PCB board. Therefore, this invention specifically divides the barrier strip 100 into multiple independent secondary barrier strips 110 and multiple independent main barrier strips 120. However, this is not sufficient; gaps must also be created between the multiple independent secondary barrier strips 110 and the multiple independent main barrier strips 120. This allows the generated airflow to effectively pass through these gaps, thereby reducing the airflow volume. Therefore, this invention specifically incorporates a tension roller 220 structure. Specifically, the outer wall of the central rod 221 has multiple coarse rolling sleeves 222 and multiple fine rolling sleeves 223. This creates a permeable gap between the main isolation belt 120 and the secondary isolation belt 110, which are respectively wound around the coarse rolling sleeves 222 and the fine rolling sleeves 223. The generated air can then effectively pass through this gap, thereby reducing the airflow. It is conceivable that if the multiple coarse rolling sleeves 222 and multiple fine rolling sleeves 223 were not provided on the outer wall of the central rod 221, no gap would be created between the main isolation belt 120 and the secondary isolation belt 110, and they would still stick together, failing to achieve the desired permeability. Furthermore, by simply providing multiple coarse rolling sleeves 222 and multiple fine rolling sleeves 223 on the outer wall of the central rod 221 (without requiring a complex structure), a permeable gap can be cleverly created between the main isolation belt 120 and the secondary isolation belt 110.

[0057] It should be emphasized that the main isolation strip 120 and the secondary isolation strip 110 are staggered, and the main isolation strip 120 is laid higher than the secondary isolation strip 110. The width of the main isolation strip 120 is greater than that of the coarse rolling sleeve 222. That is, the bonding part 121 on the edge of the main isolation strip 120 extends from the coarse rolling sleeve 222 and extends above the secondary isolation strip 110. In this way, the main isolation strip 120 and the secondary isolation strip 110 overlap at the bonding part 121, which can prevent dripping ink from falling through the gap between the main isolation strip 120 and the secondary isolation strip 110. While ensuring that the main isolation strip 120 and the secondary isolation strip 110 are independent of each other, they can still block ink in all directions.

[0058] On the other hand, the main isolation belt 120 and the secondary isolation belt 110 are independent of each other. Even if they are damaged during use, only the damaged main isolation belt 120 or the secondary isolation belt 110 needs to be replaced, which can effectively save fabric and reduce maintenance costs.

[0059] The improvements to the barrier belt 100 and tension roller 220 have the following beneficial effects:

[0060] 1. The barrier belt 100 is divided into multiple independent secondary barrier belts 110 and multiple independent main barrier belts 120, and there is a gap between adjacent secondary barrier belts 110 and main barrier belts 120, so that the air volume generated during the rotation process is reduced; the fine rolling sleeve 223 and the coarse rolling sleeve 222 are both rolledly connected to the center rod 221, which can reduce the resistance when the barrier belt 100 rotates, and the two work together to reduce the noise generated during the printing process;

[0061] 2. The fine rolling sleeve 223 and the coarse rolling sleeve 222 cooperate to form a continuous concave-convex structure on the outside of the central rod 221, so that the secondary isolation strip 110 covering it is staggered from the main isolation strip 120, reducing the friction between the main isolation strip 120 and the secondary isolation strip 110. At the same time, the main isolation strip 120 is provided with a fitting part 121 covering the secondary isolation strip 110, preventing ink from seeping in from the gap, so that the main isolation strip 120 and the secondary isolation strip 110 do not interfere with each other while ensuring the ability to block ink.

[0062] 3. When the barrier strip 100 is damaged, only the main barrier strip 120 or the secondary barrier strip 110 that is damaged needs to be replaced. The entire barrier strip 100 does not need to be replaced, which can effectively save fabric and reduce maintenance costs.

[0063] The aforementioned improvements reduced the resistance of the barrier belt 100 as it moves with the follower slide 500, lowered the noise generated during operation, and made the barrier belt 100 easier to replace. However, the barrier belt 100's function in the inkjet printer is to prevent ink from dripping into the electric guide rail 400. Its ink adsorption capacity is limited, and the drying of the ink also weakens the flexibility of the barrier belt 100, making it prone to wear during rotation. To ensure the normal operation of the equipment, the barrier belt 100 needs to be replaced periodically. Replacing the barrier belt 100 requires the cooperation of two operators. The two operators stand at opposite ends of the equipment. The operator standing at the feed position connects one end of the barrier belt 100 to the first docking part 510, then hangs the other end of the barrier belt 100 on a long pole (such as a clothes support pole) and pushes it under the base 200. The other operator then catches the barrier belt 100, pulls it out from under the base 200, and secures the other end of the barrier belt 100 to the second docking part 520. On the other hand, the barrier belt 100 connects to the follower slide 500 after passing over the back of the base 200, and it needs to be kept taut. When securing the other end of the barrier belt 100 to the second docking part 520, it needs to be pulled taut; excessive force can cause the barrier belt 100 to break. Therefore, simplifying the replacement steps of the barrier belt 100 to make it easier to replace is also a problem that needs to be solved.

[0064] To resolve the above issues, please refer to [link / reference]. Figure 6 and Figure 7A quick-change assembly is provided at the location of the first docking part 510 and the second docking part 520. The quick-change assembly includes a floating bracket 610, a flip plate 620, a clamping plate 630 and a return spring 640.

[0065] Please see Figure 6 and Figure 7 The floating bracket 610 is slidably mounted on the follower slide 500. The return spring 640 provides elastic force to keep the floating bracket 610 in close contact with the outer wall of the follower slide 500. The floating bracket 610 is provided with a limit pin 611. The flip plate 620 is rotatably mounted on the follower slide 500. The flip plate 620 is provided with a locking hole 621 that matches the limit pin 611.

[0066] There is a gap between the flip plate 620 and the floating bracket 610, which is used to accommodate the clamping plate 630. The clamping plate 630 is provided with a positioning hole 631 that matches the limiting pin 611, and the clamping plate 630 is connected to the end of the barrier strip 100, that is, both ends of the barrier strip 100 are provided with clamping plates 630.

[0067] Please see Figure 7 The end of the limiting pin 611 is provided with a spherical anti-jamming part 612.

[0068] Please see Figure 8 and Figure 9 The quick-change assembly also includes an auxiliary track 650, one end of which is located on the first docking part 510, and the other end of the auxiliary track 650 is connected to the second docking part 520 on the reverse side of the base 200. A hook 651 is provided on the outer wall of the auxiliary track 650, and a T-shaped docking part 632 matching the hook 651 is provided on the clamping plate 630.

[0069] Please see Figure 8 and Figure 9 The process of replacing barrier band 100 is as follows:

[0070] First, place the clamp 630 on one end of the barrier strip 100 on the floating bracket 610 at the first docking part 510, and limit the clamp 630 by penetrating the positioning hole 631.

[0071] Next, the operator stands in the original position and starts the electric guide rail 400, causing the follower slide 500 to slide toward the print head 300. After the follower slide 500 moves to the end away from the operator, the operator picks up the clamp 630 on the other end of the barrier belt 100, and hangs the T-shaped docking part 632 on the clamp 630 onto the hook 651 of the auxiliary track 650. The operator starts the electric guide rail 400 to return the follower slide 500. As the follower slide 500 approaches the operator, the clamp 630 hanging on the auxiliary track 650 is transported to the other side of the base 200.

[0072] At this point, the operator can walk behind the base 200 and remove the clamping plate 630 from the auxiliary track 650. The electric guide rail 400 is then activated again to allow the follower slide 500 to slide towards the print head 300. The follower slide 500 will then approach the operator's position and tighten the barrier belt 100. After the follower slide 500 has moved to the operator's position, the clamping plate 630 on the other end of the barrier belt 100 is placed on the floating bracket 610 at the second docking section 520. Finally, the flipping pieces 620 on the first docking section 510 and the second docking section 520 are flipped so that they cover the clamping plate 630.

[0073] The replacement of the barrier band 100 can be completed by a single operator. A return spring 640 is provided between the floating bracket 610 and the base 200. When the operator fixes the clamp 630 on the second docking part 520, pulling the barrier band 100 will cause the floating bracket 610 at the first docking part 510 to shift, preventing the barrier band 100 from being damaged. After the clamp 630 is fixed, the return spring 640 resets the floating bracket 610, ensuring that the barrier band 100 is taut after the clamp 630 is fixed. The floating bracket 610 can be locked after the flip plate 620 is closed. The operation process is simple.

[0074] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
