Description

Technical Field

[0001] The present invention relates to the technical field of resin plate cleaning, and more specifically, to an NMP cleaning machine commonly used for resin plates of various generations and line sizes and a method for using the same. Background Art

[0002] With the improvement of people's scientific and technological level, the LCD panel industry is developing faster and faster, and flexible printing technology is widely used. In this printing technology, flexible resin plates are used for printing and plate making. When the flexible resin printing plate is used on the printing machine, on the one hand, the cleanliness of the printing plate must be ensured, and on the other hand, the adhesion between the printing plate film surface and the alignment liquid must be ensured. Usually, the main component of the alignment liquid, NMP (N-methylpyrrolidone), is used to aging and soak the printing plate, that is, a large amount of NMP solvent is poured into a square tank until the printing plate is completely covered. A large amount of foreign matter floating in the NMP solvent after multiple aging and soaking cannot be filtered and removed. If it continues to be used in the aging and soaking of the next plate on the production line, it will affect the cleanliness and aging effect of the next plate. In general, it is directly discharged and disposed of after aging and soaking. However, NMP is the main component of the alignment liquid, and the procurement cost is high. If it is directly discharged, it will cause low material utilization and property loss. In addition, NMP is a hazardous chemical, and manual operation has major safety hazards when exposed to chemicals. At the same time, conventional NMP cleaning machines are mostly designed for the size of a single-generation line of the client. The two ends of the resin plate are designed with fixtures to fix the plate on the equipment. The high-frequency ultrasonic vibration cleaning process ensures the cleaning effect of the plate and the position of the plate does not shift. However, as a resin plate manufacturer, our company supplies to multi-generation customer groups around the world. It is impossible to equip each generation line with a cleaning machine, so we need to design a universal NMP cleaning machine that can meet the cleaning of various sizes of generation lines before shipment, and apply it to the cleaning steps on the production line.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0019] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1-3As shown, the present invention provides an NMP cleaning machine commonly used for resin plates of various generations of line sizes, comprising a loading car 1, an NMP cleaning chamber 2, a DIW cleaning chamber 3, and a unloading car 4 which are sequentially connected and arranged along the direction of the production line, the NMP cleaning chamber 2 is connected to the DIW cleaning chamber 3 and a loading port 6 is arranged on the side of the NMP cleaning chamber 2 facing the loading car 1, and a unloading port is arranged on the side of the DIW cleaning chamber 3 facing the unloading car 4, the tops of the loading car 1 and the unloading car 4 are at the same height and are respectively provided with transmission mechanisms 5 along the direction of the production line, the vertical position of the transmission mechanism 5 corresponds to the loading port 6 and the unloading port, a plate transport clamp 7 is arranged on the transmission mechanism 5, the plate transport clamp 7 has a groove 8 for accommodating resin plates 10 of various generations of line sizes, a row of pressure rods 9 are arranged on the top of the groove 8, and the pressure rods 9 are used to press and fix the resin plates 10 in the groove 8 downward, an NMP soaking tank 11 is arranged at the bottom of the NMP cleaning chamber 2, and a first A transmission device 12 is provided in the NMP cleaning chamber 2, and an NMP spray device 13 is provided in the NMP cleaning chamber 2 for spray-rinsing the resin plate 10. A first lifting device 14 is also provided in the NMP cleaning chamber 2 for operating the first transmission device 12 to move up and down, so as to sink the plate transport clamp 7 on the first transmission device 12 into the NMP soaking tank 11 or take it out. A DIW soaking tank 15 is provided at the bottom of the DIW cleaning chamber 3, and a second transmission device 16 is provided in the middle along the production line direction. A DIW spray device 17 is provided in the DIW cleaning chamber 3 for spray-rinsing the resin plate 10. A second lifting device 18 is also provided in the DIW cleaning chamber 3 for operating the second transmission device 16 to move up and down, so as to sink the plate transport clamp 7 on the second transmission device 16 into the DIW soaking tank 15 or take it out. Wind cutting devices 19 are respectively provided in the NMP cleaning chamber 2 and the DIW cleaning chamber 3 for drying the rinsed resin plate 10.

[0021] The plate transport clamp 7 can carry and fix various sizes of generation line plates. When various sizes of generation line plates need to be NMP cleaned, the plates are first placed flat in the groove 8. The volume of the groove 8 is designed according to the maximum size of the cleaned plate. The resin plate 10 is fixed by the design of the built-in pressure rod 9 to prevent floating and displacement. The transmission system of the entire NMP cleaning machine includes a transmission mechanism 5 on the loading car 1, a first transmission device 12 in the NMP cleaning chamber 2, a second transmission device 16 in the DIW cleaning chamber 3, and a transmission mechanism 5 on the unloading car 4. The plate transport clamp 7 carrying the resin plate 10 is transported in sequence. After the resin plate 10 enters the NMP cleaning chamber 2, the resin plate 10 is transported by the transmission mechanism 5 to the first transmission device 12, a space for closing the loading port 6 is left between the first transmission device 12 and the transmission mechanism 5 of the loading vehicle 1. After the resin plate 10 completely enters the NMP cleaning chamber 2, the transmission movement is stopped, and the switch doors (including the loading port 6) of the NMP cleaning chamber 2 on both sides of the transportation path are closed. The first lifting device 14 directly drives the first transmission device 12 to move up and down. When the first transmission device 12 moves, it drives the plate transport clamp 7 carried by it to move synchronously. First, the first lifting device 14 moves the first transmission device 12 downward, so that the plate transport clamp 7 sinks together and is immersed below the liquid surface of the NMP immersion tank 11 to achieve full coverage immersion. After the immersion is completed, the first transmission device 12 and the plate transport clamp 7 are lifted to the bottom by the first lifting device 14. The position before sinking is equivalent to returning to the initial height position of entering the NMP cleaning chamber 2, and the NMP spray device 13 is started to spray the resin plate 10. After cleaning, the wind knife is used to blow and dry the plate 10 through the wind cutting device 19 to ensure that the surface of the plate of each size generation line after cleaning is maintained at a high cleanliness and no water droplets. After the NMP cleaning is completed, the NMP cleaning chamber 2 is opened, and the first transmission device 12 is started to convey the plate transport clamp 7 to the second transmission device 16. Similarly, the switch doors (including the unloading port) on both sides of the transportation path of the DIW cleaning chamber 3 are closed, and the second lifting device 18 is started to drive the first transmission device 12 and the plate transport clamp 7 carried by it to move downward, and sink it into the DIW soaking tank. The resin plate 10 is immersed in DIW pure water below the liquid level of the body 15, and then the second transmission device 16 and the plate transport clamp 7 are lifted to the position before sinking by the second lifting device 18, and returned to the initial height position, and the DIW spraying device 17 is started to spray the surface of the resin plate 10 with pure water. The liquid after spraying on the surface of the resin plate 10 will also be blown and dried by the wind cutting device 19, and finally transmitted from the discharge port to complete the cleaning of the resin plate 10. It not only solves the problem of low solvent utilization rate of the existing NMP immersion device, but also solves the problem that one cleaning equipment cannot be used for cleaning resin plates 10 of various generations and line sizes, and also improves the cleaning efficiency and cleaning effect of the resin plate 10 compared with conventional immersion and cleaning equipment processes.

[0022] In another technical solution, Figure 1-2As shown, lifting doors are respectively provided at the loading port 6, the unloading port and the connection between the NMP cleaning chamber 2 and the DIW cleaning chamber 3, and an exhaust gas discharge port 20 is provided at the top of the DIW cleaning chamber 3. The electrically controlled lifting door is provided to facilitate the control and closure of the corresponding NMP cleaning chamber 2 or DIW cleaning chamber 3. After the NMP cleaning is completed, the lifting door on the front side of the transportation direction will be opened to bring the plate transport clamp 7 and the exhaust gas into the DIW cleaning chamber 3, partially dissolved in pure water, and the final chemical solvent exhaust gas is discharged centrally through the exhaust gas discharge port 20 of the DIW cleaning chamber 3 to ensure environmental safety in the area.

[0023] In another technical solution, Figure 1-2 As shown, the exhaust gas outlet 20 is opened at the top of the DIW cleaning chamber 3 near the middle of one side, and the front and rear sides of the top of the DIW cleaning chamber 3 are inclined upward toward the exhaust gas outlet 20 to guide the internal airflow and discharge it in a centralized manner.

[0024] In another technical solution, Figure 1-3 As shown, the plate transport clamp 7 is symmetrically provided with a slot member 21 on both sides of the groove 8 perpendicular to the transmission direction. The slot member 21 includes a pair of inner vertical plates 22 and outer vertical plates 23 which are parallel to the transmission direction and arranged in sequence away from the center of the resin plate 10. The tops of the inner vertical plates 22 and the outer vertical plates 23 are commonly connected to a top plate 24, and the bottoms are respectively fixedly connected to the plate transport clamp 7. One side of the inner vertical plate 22 is inclined downward toward the center to extend through and form a mounting hole 25. The bottom of the mounting hole 25 extends upward to form a clamping hole 26. The width of the mounting hole 25 is greater than the outer diameter of the pressure rod 9. The height of the clamping hole 26 is greater than the sum of the height of the largest size of the resin plate 10 and the outer diameter of the pressure rod 9.

[0025] The outer vertical plate 23 and the top plate 24 serve as a fixed connection structure with the inner vertical plate 22. On a pair of opposite inner vertical plates 22, mounting holes 25 and clamping holes 26 are symmetrically opened. The pressure rod 9 slides downward from the entrance of the mounting hole 25 into the clamping hole 26. The vertical position of the pressure rod 9 in the clamping hole 26 is adjusted according to the size and thickness of the resin plate 10, and the pressure rod 9 is limited by the top of the clamping hole 26. If needed, a downward limiting structure for the pressure rod 9, such as a clamping block, can be set in the clamping hole 26. In another technical solution, Figure 3 As shown, an annular ring 27 is sleeved and connected to the outer periphery of the pressure rod 9 at intervals along the axial direction to abut against the top surface of the resin plate 10 downward to avoid scratching the surface of the resin plate 10. In another technical solution, Figure 1 As shown, transparent windows 28 are respectively provided on the left and right sides of the NMP cleaning chamber 2 and the DIW cleaning chamber 3 in the transmission direction, so that technicians can observe the interior of the cleaning chambers.

[0026] In another technical solution, Figure 1-2 As shown, the loading trolley 1 is detachably connected to the side of the NMP cleaning chamber 2 away from the DIW cleaning chamber 3, and the unloading trolley 4 is detachably connected to the side of the DIW cleaning chamber 3 away from the NMP cleaning chamber 2. The loading port 6 and the unloading port are universal in front and back, and the detachable connection form can be freely combined to freely combine the loading trolley 1 and the unloading trolley 4. The loading trolley 1 and the unloading trolley 4 can be set to the same structure to reduce the occupied space of the overall cleaning machine.

[0027] In another technical solution, Figure 2 As shown, the first lifting device 14 and the second lifting device 18 respectively include a group of driving motors and multiple transmission wheels. The driving motors are fixed on the inner wall of the corresponding NMP cleaning chamber 2 or the DIW cleaning chamber 3. The multiple transmission wheels are connected to the inner wall of the corresponding NMP cleaning chamber 2 or the DIW cleaning chamber 3 through bearings and are located above the driving motors. The output end of the driving motor is coaxially connected with a driving gear. The driving gear, multiple transmission wheels and the end of the first transmission device 12 or the second transmission device 16 of the same group are jointly wound with a meshing chain. The driving gear is driven to rotate by the driving motor, and the vertical movement of the first transmission device 12 or the second transmission device 16 is achieved under the action of the transmission wheels.

[0028] In the NMP cleaning chamber 2 and the DIW cleaning chamber 3, in addition to the driving motor, a commutator, a coupling, a lifting shaft, etc. are also provided, which are used for power steering and power balancing of the plate transport clamp 7 in the corresponding NMP or DIW cleaning chamber 3. The driving motor starts the lifting effect of the plate transport clamp 7 when it rotates forward, and moves the plate transport clamp 7 downward when it rotates reversely. Under the control of the meshing chain and the driving motor, the moving position of the plate transport clamp 7 can be kept equal by rotating the same number of circles. The entire driving system to which the first transmission device 12, the second transmission device 16, the first lifting device 14, and the second lifting device 18 belong mainly plays a transmission role. The existing technologies of various related structural products are very mature and will not be repeated here. In another technical solution, Figure 2 As shown, an ultrasonic device 29 and a driving device are respectively provided in the NMP cleaning chamber 2 and the DIW cleaning chamber 3. The driving device drives the ultrasonic device 29 to rise or fall, so that the ultrasonic device 29 enters or moves out of the corresponding NMP soaking tank 11 or the DIW soaking tank 15.

[0029] The NMP soaking tank 11 and the DIW soaking tank 15 are both equipped with an ultrasonic vibration plate device, and the ultrasonic device 29 can be selectively moved by a driving device to turn on the ultrasonic function or adjust the ultrasonic power to improve the cleaning effect.

[0030] The present invention also provides a method for using an NMP cleaning machine that is universally applicable to resin plates 10 of all generations of line sizes, Figure 1-3 , including the following steps: S1. When the generation line plates of various sizes need to be cleaned with NMP, the resin plate 10 is first placed flat in the groove 8, and the surface of the resin plate 10 is fixed by the pressing rod 9 to press and fix the resin plate 10 to be cleaned.

[0031] S2, open the lifting door of the loading port 6, place the plate transporting clamp 7 on the transmission mechanism 5 of the loading vehicle 1, carry and transport the plate transporting clamp 7 to the NMP cleaning chamber 2 through the transmission mechanism 5, transfer the plate transporting clamp 7 to the first transmission device 12, close the lifting doors on both sides of the NMP cleaning chamber 2, move the first transmission device 12 downward through the first lifting device 14, sink the plate transporting clamp 7 into the NMP soaking tank 11, and soak the resin plate 10 in full coverage. The transmission mechanism 5 can generally choose a roller transmission mode. If an ultrasonic device 29 is provided, it will sink until the NMP solvent liquid level submerges the ultrasonic vibration plate, and the corresponding ultrasonic soaking cleaning time is set according to the size of the plate.

[0032] S3, the first transmission device 12 is moved up to the height before the downward movement through the first lifting device 14, generally to the middle position of the chamber, and the resin plate 10 is sprayed and rinsed by the NMP spray device 13, and the NMP rinse is performed to enhance the surface cleaning effect, and then the surface of the resin plate 10 is blown and dried by the wind knife device 19 in the room.

[0033] S4, opening the lifting door between the NMP cleaning chamber 2 and the DIW cleaning chamber 3, starting the first transmission device 12 to transfer the plate transport clamp 7 to the second transmission device 16 in the DIW cleaning chamber 3, and closing the lifting doors on both sides of the DIW cleaning chamber 3.

[0034] S5. In a manner similar to steps S2-S3, the second transmission device 16 is moved down by the second lifting device 18, so that the plate transporting clamp 7 sinks into the DIW soaking tank 15, and the resin plate 10 is fully soaked. The second transmission device 16 is moved up by the second lifting device 18 to the height before the downward movement, and the resin plate 10 is sprayed by the DIW spray device 17, and then the surface of the resin plate 10 is air-knife-blown and dried by the indoor wind-cut device 19. A large amount of solvent droplets will remain on the surface of the resin plate 10 washed with NMP and DIW liquids, and the residual liquid on the surface and back of the plate needs to be blown away by the wind-cut device 19. The wind-cut device 19 is equipped with a heating pump with an air outlet temperature of about 50°C and a blowing time of 30 minutes to ensure that the surface of the cleaned resin plate 10 is clean and dry.

[0035] S6, opening the lifting door of the discharge port, and transmitting the plate transporting clamp 7 to the transmission mechanism 5 of the unloading vehicle 4 through the second transmission device 16, thereby completing the entire cleaning process.

[0036] The present invention is a NMP cleaning machine and a method for using the same, which is generally applicable to resin plates 10 of all generations of lines. The cleaning machine body includes an NMP cleaning chamber 2, a DIW cleaning chamber 3, a loading car 1, and an unloading car 4. When cleaning the resin plate 10, a plate transport clamp 7 that can accommodate all generations of lines of various sizes is provided for carrying and fixing. This allows the cleaning machine to be generally applicable to cleaning resin plates 10 of all generations of lines and ensures the cleaning effect without positional displacement during the cleaning process. The plate transport clamp 7 is sequentially transported by the transmission mechanism 5 and the first transmission device 12 and the second transmission device 16 into the NMP cleaning chamber 2 and the DIW cleaning chamber 3, and is lowered to the NMP cleaning chamber 2 by the first lifting device 14. An aging immersion treatment is carried out in the NMP immersion tank 11, spray-type flushing is carried out through the NMP spray device 13, and then it is dried through the wind cutting device 19. In the DIW cleaning chamber 3, it is sunk to the DIW immersion tank 15 through the first lifting device 14 for aging immersion treatment, and spray-type flushing is carried out through the DIW spray device 17 to enhance the surface cleaning effect, and then it is dried through the wind cutting device 19. It can ensure that the surface of the cleaning plates of various sizes of the generation line materials is maintained in a high cleanliness state without water droplets and stains after cleaning. The entire cleaning process equipment has a compact structure, high cleaning efficiency, good cleaning effect, and multiple uses, which greatly saves the cleaning cost of the resin plate 10.

[0037] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
