Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of PC board processing equipment, and more specifically, to a coating equipment for PC board processing. Background Technology
[0002] PC sheet, short for polycarbonate sheet, also known as polyester sheet or Kapron sheet, is a high-performance engineering plastic sheet. However, PC sheet itself does not resist ultraviolet (UV) radiation. Long-term exposure to UV rays will cause the sheet to age and become brittle, severely affecting its impact resistance and safety performance. Therefore, coatings, especially UV-resistant coatings, are needed to effectively reduce UV penetration and extend the sheet's lifespan. Because of electrostatic attraction, PC sheet surfaces easily attract dust. While the dust has relatively low adhesion, it is difficult to remove completely through conventional wiping methods. Therefore, to ensure the quality of the PC sheet coating, the PC sheet surface needs to be dusted before coating processing.
[0003] In the existing technical solution, Chinese Patent No. CN216460552U discloses a coating device for PC glass plates, including a roller conveyor. A protective cover is fixed above the roller conveyor. The protective cover is divided into a dirt removal zone, a coating zone and a curing zone. A dust removal mechanism is provided in the dirt removal zone. The dust removal mechanism first stabilizes the compressed air in the distribution pipe, and then introduces it into the air blowing head through multiple air distribution pipes, so that the air pressure in the air blowing head is relatively uniform, thereby making the blown airflow stable and facilitating the removal of dust.
[0004] The shortcomings of the above-mentioned existing technical solutions are that since the device only performs dust removal and subsequent coating treatment on one side of the PC glass plate, if the other side needs to be treated in the same way, the PC glass plate must be flipped or replaced with another device that is dedicated to treating the other side. This undoubtedly increases the number of operation steps and time costs in the production process and reduces the overall processing efficiency. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a coating equipment for PC board processing, which solves the technical problem that the prior art device only performs dust removal and subsequent coating treatment on one side of the PC glass board, and the PC glass board must be flipped or replaced with another equipment specifically for processing the other side, resulting in increased costs.
[0006] According to one aspect, at least one embodiment of this disclosure provides a coating application apparatus for PC board processing, comprising:
[0007] The equipment rack and the conveying assembly, wherein the conveying assembly is disposed inside the equipment rack;
[0008] The equipment includes a drive motor and a dust removal assembly, wherein the drive motor is mounted on one side of the equipment frame and the dust removal assembly is disposed inside the equipment frame.
[0009] A feed pump and a coating assembly are provided, wherein the feed pump is located on one side of the equipment frame and the coating assembly is located inside the equipment frame;
[0010] A pair of shrouds and a drying assembly, wherein the shrouds are respectively fixed to the top and bottom of the equipment rack, and the drying assembly is disposed inside the shrouds;

Each of the several conveying wheels on one side is provided with a driven gear at its lower end. A drive shaft is provided at the bottom of the equipment frame. The drive shaft is rotated by a motor. Several drive gears are provided on the drive shaft, and all drive gears mesh with the driven gears.
[0012] As a further technical solution, the coating assembly includes a pair of guide frames, both of which are disposed at the top and bottom of the equipment frame. A conveying pipe is movably connected inside the pair of guide frames, and several coating nozzles are disposed at the bottom of the conveying pipe.
[0013] As a further technical solution, the conveying pipe is connected to the feeding pump, one end of the conveying pipe is connected to a transmission rod via a pin-driven rotating wheel, and a bidirectional shaft frame and a control motor are provided on the side surface of the equipment frame.
[0014] As a further technical solution, both the output end of the control motor and the bidirectional shaft are provided with transmission wheels, which are connected by belt drive. The two ends of the bidirectional shaft are respectively rotatably connected to a pair of transmission rods by pins.
[0015] As a further technical solution, the dust removal assembly includes a pair of electrostatic adsorption rollers, both of which rotate within the equipment frame. One of the electrostatic adsorption rollers is connected to the output end of the drive motor, and a transmission gear is provided at one end of the electrostatic adsorption roller.
[0016] As a further technical solution, the top and bottom of the equipment frame are fixed with gas collection hoods, the surface of the gas collection hoods is provided with centrifugal fans and filter gas collection boxes, and the inner surface of the gas collection hoods is provided with several horizontal holes.
[0017] As a further technical solution, the drying assembly includes several ultraviolet lamps, which are installed on the inner surface of the shroud. An outer cover is provided on the top of the shroud, and an air intake fan and a filter are installed inside the outer cover.
[0018] As a further technical solution, the gas collecting hood is provided with several scraper strips on the surface of the electrostatic adsorption roller.
[0019] As a further technical solution, both ends of the bidirectional shaft bracket are eccentric structures.
[0020] As a further technical solution, a number of support rollers are provided on one side of the equipment frame.
[0021] The beneficial effects of the embodiments disclosed herein are as follows:
[0022] 1. This disclosure includes a conveying assembly that, through the cooperation of a drive shaft, a drive gear, and a driven gear, enables the synchronous rotation of multiple conveying wheels, stably clamping and conveying PC boards. The inclined and concave design of the conveying wheel surfaces can accommodate PC boards of different thicknesses, ensuring the stability of the PC boards during conveying and providing a reliable foundation for subsequent dust removal, coating, and drying processes.
[0023] 2. The dust removal components in this disclosure offer significant advantages. The electrostatic adsorption rollers can efficiently adsorb dust from the PC board surface, and the transmission gears enable the two adsorption rollers to work synchronously, expanding the dust removal range. The combination of the air collection hood, centrifugal fan, and filter air collection box can promptly collect the adsorbed dust, preventing dust from re-contaminating the PC board. The scraper further enhances the dust removal effect, ensuring the cleanliness of the PC board surface and improving the coating quality.
[0024] 3. In this disclosure, the coating assembly plays a crucial role. The eccentric structure of the bidirectional shaft frame, in conjunction with the control motor and transmission wheels, enables the conveying pipe to move rapidly and repeatedly within the guide frame. The coating nozzles can evenly spray the coating onto the PC board surface, ensuring the uniformity and quality of the coating, improving coating efficiency, reducing coating waste, and meeting the process requirements for PC board coating.
[0025] 4. In this disclosure, the drying components are highly effective. The ultraviolet lamps can quickly dry the coating material, accelerating the production process. The intake fan and filter ensure a clean drying environment while effectively dissipating heat, preventing excessive temperature from affecting the performance of the PC board and coating material. This ensures the stability and reliability of the drying process and improves the processing quality of the PC board. Attached Figure Description

[0039] like Figures 1-5 As shown, it illustrates a coating application apparatus for PC board processing according to an embodiment of the present disclosure, comprising:
[0040] The equipment rack 1 and the conveying assembly 5 are arranged inside the equipment rack 1;
[0041] The drive motor 2 and the dust removal component 7 are installed on one side of the equipment frame 1, and the dust removal component 7 is installed inside the equipment frame 1.
[0042] The feed pump 3 and the coating assembly 6 are provided. The feed pump 3 is located on one side of the equipment frame 1, and the coating assembly 6 is located inside the equipment frame 1.
[0043] A pair of partitions 4 and a drying assembly 8 are provided. The partitions 4 are fixed to the top and bottom of the equipment frame 1, respectively, and the drying assembly 8 is disposed inside the partitions 4.
[0044] The conveying assembly 5 includes several conveying wheels 5-1, which are respectively installed on the inner surfaces of both sides of the equipment frame 1. Each of the several conveying wheels 5-1 on one side is provided with a driven gear 5-2 at its lower end. A drive shaft 5-3 is provided at the bottom of the equipment frame 1. The drive shaft 5-3 is rotated by a motor. Several drive gears 5-4 are provided on the drive shaft 5-3, and all drive gears 5-4 mesh with the driven gears 5-2.
[0045] In some examples, to achieve the effect of clamping and conveying PC boards, a conveying assembly 5 is designed, including several conveying wheels 5-1. The conveying wheels 5-1 are installed on both sides inside the equipment frame 1 to support the two ends of the PC board. The surface of the conveying wheels 5-1 is inclined and concave, which can clamp the PC board according to its thickness. One side of the conveying wheel 5-1 has multiple driven gears 5-2 at its lower end. The drive shaft 5-3 is at the bottom of the equipment frame 1, and multiple drive gears 5-4 on its surface mesh with the driven gears 5-2, which can control the synchronous rotation of multiple conveying wheels 5-1 to achieve the conveying effect.
[0046] like Figures 1-5 As shown, this embodiment proposes a coating component 6 including a pair of guide frames 6-1, both of which are set at the top and bottom of the equipment frame 1. A conveying pipe 6-2 is movably connected inside the pair of guide frames 6-1. Several coating nozzles 6-3 are set at the bottom of the conveying pipe 6-2. The conveying pipe 6-2 is connected to the feed pump 3. One end of the conveying pipe 6-2 is connected to a transmission rod 6-4 via a pin-driven rotating wheel. A bidirectional shaft frame 6-5 and a control motor 6-6 are set on the side surface of the equipment frame 1. A transmission wheel 6-7 is set on both the output end of the control motor 6-6 and the bidirectional shaft frame 6-5. The transmission wheels 6-7 are connected to each other via belt drive. The two ends of the bidirectional shaft frame 6-5 are respectively rotatably connected to the pair of transmission rods 6-4 via pins.
[0047] In some examples, to achieve uniform coating, a coating assembly 6 is designed. Two guide frames 6-1 are provided at the top and bottom of the equipment frame 1. Both guide frames 6-1 are movably fitted inside the guide frame 6-1 and connected to the feed pump 3. The guide frame 6-1 can move a certain distance left and right within the guide frame 6-1. Multiple coating nozzles 6-3 on the surface of the conveying pipe 6-2 are used to spray material downwards. A bidirectional shaft 6-5 is rotatably connected to one side of the equipment frame 1 and is driven to rotate by a control motor 6-6 and a transmission wheel 6-7. Both ends of the bidirectional shaft 6-5 are connected to the two conveying pipes 6-2 through a transmission rod 6-4. The bidirectional shaft 6-5 can drive the two conveying pipes 6-2 to move quickly and repeatedly, making the material coverage more uniform.
[0048] like Figures 1-5As shown, this embodiment proposes a dust removal component 7 including a pair of electrostatic adsorption rollers 7-1, both of which rotate within the equipment frame 1. One of the electrostatic adsorption rollers 7-1 is connected to the output end of the drive motor 2. A transmission gear 7-2 is provided at one end of the electrostatic adsorption roller 7-1. A gas collection hood 7-3 is fixed at the top and bottom of the equipment frame 1. A centrifugal fan 7-4 and a filter gas collection box 7-5 are provided on the surface of the gas collection hood 7-3. Several horizontal holes 7-6 are opened on the inner surface of the gas collection hood 7-3.
[0049] In some examples, a dust removal component 7 is designed to achieve the effect of dust removal on the surface of PC boards. It includes two electrostatic adsorption rollers 7-1 rotatably connected inside the equipment frame 1. The drive motor 2 can control the rotation of one of the electrostatic adsorption rollers 7-1, and through the transmission gear 7-2, the two electrostatic adsorption rollers 7-1 rotate synchronously, which can clean the surface of the PC boards being transported and adsorb and carry the dust down. Two air collection hoods 7-3 are located outside the electrostatic adsorption rollers 7-1. The centrifugal fan 7-4 and the filter dust collection box are installed on the surface of the air collection hoods 7-3, which can generate suction force through the horizontal holes 7-6 on the inner surface of the air collection hoods 7-3. The horizontal holes 7-6 are distributed outside the electrostatic adsorption rollers 7-1, which can quickly absorb the dust carried up into the filter dust collection box. The filter dust collection box is a split connection and can be disassembled for cleaning of the dust inside.
[0050] like Figures 1-5 As shown, this embodiment proposes a drying component 8 including several ultraviolet lamps 8-1, the ultraviolet lamps 8-1 are installed on the inner surface of the shroud 4, the top of the shroud 4 is provided with an outer cover 8-2, and an air intake fan 8-3 and a filter screen 8-4 are installed inside the outer cover 8-2.
[0051] In some examples, to achieve rapid drying of the coated material, a drying assembly 8 is designed, including multiple ultraviolet lamps 8-1. The ultraviolet lamps 8-1 are installed on the inner surface of the shroud 4 and are evenly distributed, so as to irradiate the surface of the PC board and dry the material quickly. Multiple outer covers 8-2 are set on the top of the shroud 4. An air intake fan 8-3 and a filter screen 8-4 are installed in the outer covers 8-2. The air intake fan 8-3 can blow air into the shroud 4, and the filter screen 8-4 can block dust and squeeze out some heat to avoid excessive internal temperature. The filter screen 8-4 can be removed for easy replacement and dust cleaning.
[0052] For example, such as Figure 5 As shown, the surface of the gas collecting hood 7-3 relative to the electrostatic adsorption roller 7-1 is provided with several scraper strips 9.
[0053] In some examples, by providing multiple scrapers 9 that contact the surface of the electrostatic adsorption roller 7-1, dust can be scraped off, thus aiding in dust collection.
[0054] For example, such as Figure 4As shown, both ends of the bidirectional bearing 6-5 are eccentric structures.
[0055] In some examples, the eccentric structure enables the bidirectional shaft 6-5 to drive the two conveying pipes 6-2 to move left and right at a constant speed.
[0056] For example, such as Figure 1 As shown, several support rollers 10 are provided on one side of the equipment frame 1.
[0057] In some examples, multiple support rollers 10 are provided for receiving the coated PC board.
[0058] In actual use: Place the PC board on the conveyor wheel 5-1 inside the equipment rack 1, start the drive motor 2, and the motor drives the transmission shaft 5-3 to rotate. The drive gear 5-4 meshes with the driven gear 5-2, causing the conveyor wheel 5-1 to rotate synchronously, thus conveying the PC board. During the conveying process, the PC board first passes through the dust removal component 7. The drive motor 2 drives one electrostatic adsorption roller 7-1 to rotate, and through the transmission gear 7-2, it causes the other electrostatic adsorption roller 7-1 to rotate synchronously, adsorbing dust on the surface of the PC board. The centrifugal fan 7-4 on the air collection hood 7-3 starts, sucking the dust into the filter air collection box 7-5 through the horizontal holes 7-6. The scraper 9 assists in cleaning the electrostatic adsorption roller 7-1. 1. Surface dust is removed, and then the PC board reaches the coating assembly 6. The feed pump 3 delivers the coating to the conveying pipe 6-2. The control motor 6-6 drives the bidirectional shaft 6-5 to rotate. Through the transmission wheel 6-7 and belt drive, the transmission rod 6-4 moves the conveying pipe 6-2 left and right within the guide frame 6-1. The coating nozzle 6-3 evenly coats the PC board. After coating, the PC board enters the drying assembly 8 area. The ultraviolet lamp 8-1 irradiates the PC board to make the coating material dry quickly. The air intake fan 8-3 blows air into the shroud 4. The filter screen 8-4 blocks dust and dissipates some heat. Finally, the PC board is received by the support roller 10 on one side of the equipment frame 1.
