Description

Technical Field

[0001] This utility model belongs to the technical field of film cleaning, and in particular relates to an automatic film cleaning machine. Background Technology

[0002] In the printed circuit board (PCB) manufacturing industry, the surface cleanliness of the film, used as the carrier for photoplotting imaging, directly affects the accuracy of circuit transfer. Traditional PCB film cleaning mainly relies on manual operation, using lint-free cloths soaked in alcohol or special solvents for manual wiping. This has the following problems: low efficiency, as manual cleaning of a single film is time-consuming and cannot quickly clean the film; low quality, as manual wiping can easily cause scratches on the PCB board, resulting in light scattering spots on the film, and residual cleaning solution can cause "crystallization contamination"; low precision, as manual wiping makes it difficult to control the wiping force and the amount of cleaning solution used, and different operators have inconsistent cleaning standards, easily leading to inconsistent cleanliness of the PCB board film.

[0003] Therefore, there is a need to provide a new type of automatic film cleaning machine. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0021] like Figures 1 to 8As shown, the automatic film cleaning machine includes a cleaning machine body 1. The cleaning machine body 1 is equipped with a film feeding and adsorption mechanism, a film cleaning mechanism, and a film unloading and adsorption mechanism. The film feeding and adsorption mechanism adsorbs the film and transfers it to the film cleaning mechanism for cleaning. The film unloading and adsorption mechanism adsorbs the cleaned film from the film cleaning mechanism and unloads it. The film feeding and adsorption mechanisms have identical structures. A moving mechanism is mounted on the top of the cleaning machine body 1, which drives the film feeding and adsorption mechanisms to reciprocate on the cleaning machine body 1. The film cleaning mechanism includes a film placement table and a spray nozzle. The film loading and suction mechanism consists of a sprayer 7 and a cleaner 8. Sprayer 7 is located near the film loading and suction mechanism, while cleaner 8 is located near the film unloading and suction mechanism. Sprayer 7 contains cleaning fluid for cleaning the film. After spraying the cleaning fluid onto the film, cleaner 8 cleans the film. A film placement platform can move back and forth below sprayer 7 and cleaner 8. After the film loading and suction mechanism places the film to be cleaned on the film placement platform, the platform moves back and forth below sprayer 7 so that sprayer 7 can spray cleaning fluid onto the film. Then, the platform moves back and forth below cleaner 8 so that cleaner 8 can clean the film. Specifically: like Figures 4 to 7 As shown, the film placement stage includes a first guide rail 2, a first slider 3, a tray 4, an adsorption platform 5, and a servo motor 6. The first guide rail 2 is mounted on the washing machine body 1. The first slider 3 is slidably connected to the first guide rail 2. The tray 4 is fixed on the first slider 3 and can reciprocate along the first guide rail 2 with the first slider 3. The adsorption platform 5 is placed inside the tray 4. The adsorption platform 5 is a vacuum adsorption system. Under vacuum, the adsorption platform 5 adsorbs the film on the film feeding adsorption mechanism. The servo motor 6 is installed below the first guide rail 2 and electrically connected to the first slider 3. When the servo motor is activated... Motor 6, the first slider 3 slides along the first guide rail 2 to bring the adsorption table 5 close to the film feeding adsorption mechanism and adsorb the film on the film feeding adsorption mechanism, and then follows the first slider 3 to move along the first guide rail 2 towards the sprayer 7 to spray cleaning liquid onto the film. Then it follows the first slider 3 to move along the first guide rail 2 towards the cleaner 8 to clean the film. After the film is cleaned, it follows the first slider 3 to move along the first guide rail 2 towards the film unloading adsorption mechanism to pick up the film on the adsorption table 5 for unloading.

[0022] To facilitate thorough cleaning of the film, a cleaning roller 9 is installed on the side of the cleaner 8 facing the adsorption table 5. The cleaning roller 9 rolls back and forth on the surface of the film to clean it. Understandably, the material of the cleaning roller 9 will not damage the film. Therefore, the cleaning roller 9 can be made of materials such as cotton plastic.

[0023] A dryer 10 is provided on the main body 1 of the cleaning machine, near the film feeding and adsorption mechanism and located next to the cleaner 8. After the film is cleaned by the cleaner 8, there may be residual cleaning liquid on the film. The dryer 10 can dry the residual cleaning liquid to ensure that the cleaned film remains dry.

[0024] like Figure 8 As shown, the moving mechanism includes a second guide rail 11, a third guide rail 12, a second slider 13, a third slider 14, a fixed frame 15, a first reduction motor 16, and a second reduction motor 17. The second guide rail 11 and the third guide rail 12 are mounted on the top ends of the cleaning machine body 1 and are arranged opposite to each other. The second slider 13 is slidably connected to the second guide rail 11, and the third slider 14 is slidably connected to the third guide rail 12. The sliding direction of the second slider 13 along the second guide rail 11 and the sliding direction of the third slider 14 along the third guide rail 12 are consistent with the sliding direction of the first slider 3 along the first guide rail 2. The fixed frame 15 is fixed to both the second slider 13 and the third slider 14 and can reciprocate along the second guide rail 11 or the third slider 14 along the third guide rail 12. The first reduction motor 16 is mounted on the second guide rail 11 to drive the second slider 13 to slide along the second guide rail 11. The second reduction motor 17 is mounted on the third guide rail 12 to drive the third slider 14 to slide along the third guide rail 12. The second guide rail 11 is close to the film feeding and adsorption mechanism, and the third guide rail 12 is close to the film unloading and adsorption mechanism. The above arrangement allows the moving mechanism to move back and forth on the top of the cleaning machine body 1. Specifically, the second guide rail 11 being close to the film feeding and adsorption mechanism allows the moving mechanism to drive the film feeding and adsorption mechanism to move back and forth on the top of the cleaning machine body 1, and the third guide rail 12 being close to the film unloading and adsorption mechanism allows the moving mechanism to drive the film unloading and adsorption mechanism to move back and forth on the top of the cleaning machine body 1. like Figure 2 , Figure 3 and Figure 8As shown, the film feeding and adsorption mechanism includes a lifting assembly and an adsorption assembly. The lifting assembly is installed inside the cleaning machine body 1 and includes two fixed rods 18, a lead screw 19, a lifting platform 20, and a lifting motor 21. The fixed rods 18 are fixedly installed inside the cleaning machine body 1 along the height direction, and the two fixed rods 18 are respectively located on both sides of the lead screw 19. The lifting platform 20 passes through the fixed rods 18 and the lead screw 19 and is rotatably connected to the lead screw 19. The lifting motor 21 is located at the top of the cleaning machine body 1, and the output shaft of the lifting motor 21 is rotatably connected to the lead screw 19. The adsorption assembly is used to adsorb the film to be cleaned on the lifting platform 20. The assembly includes a top plate 22, a middle plate 23, and an adsorption plate 24 arranged from top to bottom. The adsorption assembly also includes several guide columns 25 arranged in the height direction. One end of each guide column 25 is fixedly connected to the top plate 22, and the other end passes through the middle plate 23 and the adsorption plate 24, and is fixedly connected to the adsorption plate 24. A pushing cylinder 26 is also provided between the top plate 22 and the middle plate 23. The upper surface of the middle plate 23 is fixedly connected to the side of the fixing frame 15, and the fixing frame 15 is located within the area enclosed by the guide columns 25, allowing the adsorption assembly to reciprocate along the second guide rail 11 with the second slider 13. The film to be cleaned is placed on the lifting platform 20, and the lifting is started. The lowering motor 21 drives the lead screw 19 to rotate, which in turn drives the lifting platform 20 to move upward along the fixed rod 18 until the film is attracted by the adsorption plate 24. After the adsorption plate 24 attracts the film, the first reduction motor 16 and the second reduction motor 17 start simultaneously. The second slider 13 moves along the second guide rail 11 towards the film placement platform, and at the same time, the third slider 14 moves along the third guide rail 12 towards the film placement platform. This moves the entire moving mechanism towards the film placement platform. At the same time, the film placement platform moves in the opposite direction to the moving mechanism as described above until the adsorption platform 5 picks up the film from the adsorption plate 24. The film cleaning operation described above is carried out. After the film cleaning operation is completed, the film unloading and adsorption mechanism moves toward the film placement table in the opposite direction to the film loading and adsorption mechanism. At the same time, the film placement table moves toward the film unloading and adsorption mechanism along the first guide rail 2 in the opposite direction to the adsorption plate 24 on the film unloading and adsorption mechanism to pick up the cleaned film on the adsorption table 5. The lifting platform 20 on the film unloading and adsorption mechanism receives the cleaned film. Then, the lifting motor 21 of the film unloading and adsorption mechanism is started so that the film loaded with the cleaned film is unloaded along with the lifting platform 20.

[0025] like Figure 2 , Figure 3As shown, to facilitate the loading of the film to be cleaned and the unloading of the cleaned film, grooves 27 are provided on both sides of the bottom of the cleaning machine body 1. That is, grooves 27 are provided on both sides of the cleaning machine body 1 near the film loading and unloading adsorption mechanisms. A film support frame 28 that can slide along the grooves 27 is placed within the grooves 27. The film support frame 28 includes several spaced film carrier plates 29, on which the film to be cleaned is placed. The bottom film carrier plate 29 has a groove 30 on its end face. A slot 31 that mates with the groove 30 is opened at the bottom of the cleaning machine body 1. When the film is loaded... During loading, the groove 30 and the empty groove 31 are designed to facilitate the lifting platform 20 to receive the film on the bottom film carrier plate 29. During loading, the lifting platform 20 is lowered to the bottom of the film carrier plate 29, and the film support frame 28 is pushed to allow the film on the film carrier plate 29 to enter the lifting platform 20. The lifting platform 20 then transfers the film to the film loading and adsorption mechanism for subsequent cleaning. During unloading, the film carrying the cleaned film is lowered to the bottom of the bottom film carrier plate 29 by the lifting platform 20 for unloading. The bottom of the film support frame 28 is equipped with casters 32 so that the film support frame 28 can slide along the slide groove 27.

[0026] To facilitate the film support bracket 28 entering the washing machine body 1 for loading or unloading after washing, the chute 27 is set as an inclined surface with respect to the ground.

[0027] like Figures 1 to 3 As shown, the bottom of the cleaning machine body 1 is equipped with pulleys 33 and foot cups 34. The pulleys 33 facilitate the movement of the cleaning machine body 1, and the foot cups 34 facilitate the fixation of the cleaning machine body 1.
