Description

Technical Field

[0001] This utility model relates to the field of solar printing screen processing technology, specifically a coating device for solar printing screen processing. Background Technology

[0002] In the early days, the coating of solar cell printing screens relied heavily on manual operation. Manual coating was not only inefficient, severely limiting the expansion of production scale, but also difficult to guarantee uniformity and stability due to the variability in manual operation. This led to problems such as uneven ink distribution and poor pattern clarity during the printing process, significantly impacting the production quality and yield of solar cells.

[0003] According to announcement number CN 217856975 U, a coating device for solar screen printing includes a coating mounting frame assembly, a coating shifting assembly, a coating assembly, and a linkage extrusion assembly. This invention achieves coordinated operation of the solar screen adhesive coating and the treatment of adhesive agglomeration during the coating process through the coordinated arrangement of the coating mounting frame structure, coating shifting structure, coating structure, and linkage extrusion structure. This ensures that the structure preventing adhesive agglomeration operates in conjunction with the coating process, and if the adhesive agglomeration treatment structure is damaged, the coating structure will also stop. This prevents quality problems in the solar screen coating caused by operators forgetting to turn on the adhesive agglomeration treatment device or the adhesive agglomeration treatment device stopping or malfunctioning during coating.

[0004] However, the device does not scrape off excess coating when coating the solar printing screen, which results in excess coating on the screen, making its surface rough and failing to effectively guarantee the quality and precision of the coating. Utility Model Content

[0007] The coating mechanism includes a rectangular frame, which is fixedly connected to the top of a support plate. A sliding sleeve is slidably connected to the left and right sides of the rectangular frame. A first fixed frame is fixedly connected to the surface of the sliding sleeve. A rotating shaft is rotatably connected to the front and rear sides of the first fixed frame. A gear is fixedly connected to the middle of the surface of the rotating shaft.

A coating roller is rotatably connected to the front and rear sides of the second fixed frame near the bottom. A fixing block is symmetrically fixed to the right side of the second fixed frame near the bottom. A scraper is fixedly connected to the other end of the fixing block.

[0008] Preferably, the first fixing frame has a hole on its front side that matches the output shaft of the first servo motor, and the surface of the output shaft of the first servo motor passes through and is rotatably connected to the hole, and the output end of the first servo motor is fixedly connected to the front end of the rotating shaft.

[0009] Preferably, the gear meshes with the rack, and the front of the second fixing frame near the bottom has a hole that matches the output shaft of the second servo motor, and the output shaft of the second servo motor passes through and is rotatably connected in the hole, and the output end of the second servo motor is fixedly connected to the front end of the coating roller.

[0010] Preferably, the coating roller is located directly below the discharge nozzle, and a flow controller is fixedly connected to the surface of the discharge nozzle.

[0011] Preferably, the fixing mechanism includes a fixing rod, which is symmetrically fixed to the top of the base. A fixing seat is fixedly connected to the top of the fixing rod. A first cylinder is fixedly connected to the bottom of the base. A lifting seat is fixedly connected to the output end of the first cylinder. Guide rods are symmetrically fixedly connected to the bottom of the lifting seat. A first fixing plate is symmetrically fixedly connected to the top of the lifting seat near the right end. A sliding rod is fixedly connected to the inner side of the first fixing plate. Clamping blocks are symmetrically slidably connected to the surface of the sliding rod. An inclined groove is opened on the top of the clamping block near the left end. A second cylinder is fixedly connected to the top left end of the lifting seat. A second fixing plate is fixedly connected to the output end of the second cylinder. A third fixing plate is fixedly connected to the bottom of the second fixing plate. A moving rod is symmetrically fixedly connected to the top of the third fixing plate.

[0012] Preferably, the bottom of the fixed base has a hole that matches the output shaft of the first cylinder, and the output shaft of the first cylinder passes through and slides up and down in the hole.

[0013] Preferably, the top of the fixed seat has a hole that matches the guide rod, and the surface of the guide rod passes through and slides up and down in the hole. The four sets of guide rods support the lifting seat, making the up and down movement of the lifting seat more stable. The surface of the moving rod is slidably connected in the inclined groove.

[0014] Compared with the prior art, this utility model provides a coating device for solar printing screen processing, which has the following beneficial effects:

[0015] 1. This coating device for solar printing screen processing uses a first servo motor to drive a rotating shaft, which in turn drives a gear. Due to the meshing of the gear and rack, this structural design allows the sliding sleeve to move stably laterally along the rectangular frame. This feature ensures that the coating roller can move evenly on the solar printing screen, providing a stable foundation for subsequent coating operations and greatly improving the efficiency and uniformity of the screen mask coating. A second servo motor drives the coating roller to rotate. The coating roller is located directly below the nozzle. When the coating material flows out of the nozzle, the coating roller can promptly and evenly coat the solar printing screen with the coating material. Simultaneously, a scraper connected to a fixed block is located behind the coating roller. It can further smooth the coated screen, removing excess coating material and making the coating smoother, further improving the coating quality and precision.

[0016] 2. This coating device for solar printing screen processing allows the lifting seat to move up and down via the telescopic movement of the first cylinder. This design enables the fixing mechanism to flexibly adjust the height of the screen according to different coating requirements, facilitating coordination with the coating mechanism and improving the device's applicability and versatility. The telescopic movement of the second cylinder drives the second and third fixing plates to move, causing the moving rod to slide within the inclined groove at the top of the clamping block. Because the clamping block slides symmetrically back and forth on the sliding rod surface, when the moving rod slides within the inclined groove, it pushes the clamping block to move in opposite directions, thus achieving the clamping and releasing operation of the solar printing screen. This clamping method is simple and reliable, ensuring that the screen does not shift during the coating process on the screen mask, guaranteeing the accuracy and consistency of the coating.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-3This utility model provides a technical solution: a coating device for processing solar printing screens, including a base 1, with support plates 2 symmetrically fixedly connected to the left and right sides of the bottom of the base 1, a coating mechanism 3 fixedly connected to the top of the support plates 2, and a fixing mechanism 4 provided on the top of the base 1.

A second fixed frame 38 is fixedly connected to the bottom of the first fixed frame 33. A hopper 39 is fixedly connected to the front and rear sides of the second fixed frame 38. A discharge nozzle 311 is fixedly connected at equal intervals to the bottom of the hopper 39. A second servo motor 312 is fixedly connected to the front of the second fixed frame 38 near the bottom. A coating roller 313 is rotatably connected to the front and rear sides of the second fixed frame 38 near the bottom.

The output shaft of the second servo motor 312 passes through and is rotatably connected in the hole.

[0032] The coating roller 313 is located directly below the discharge nozzle 311, and a flow controller is fixedly connected to the surface of the discharge nozzle 311.

[0033] Example 2

[0034] Please see Figure 4-5 Furthermore, based on Embodiment 1, a fixing mechanism 4 is obtained.

[0035] The fixing mechanism 4 includes a fixing rod 41, which is symmetrically fixed to the top of the base 1. A fixing seat 42 is fixedly connected to the top of the fixing rod 41. A first cylinder 43 is fixedly connected to the bottom of the base 1. A lifting seat 44 is fixedly connected to the output end of the first cylinder 43. A guide rod 45 is symmetrically fixed to the bottom of the lifting seat 44. A first fixing plate 46 is symmetrically fixed to the top of the lifting seat 44 near the right end. A sliding rod 47 is fixedly connected to the inner side of the first fixing plate 46. A clamping block 48 is symmetrically slidably connected to the surface of the sliding rod 47. A slanted groove 49 is opened on the top of the clamping block 48 near the left end. A second cylinder 411 is fixedly connected to the top left end of the lifting seat 44. A second fixing plate 412 is fixedly connected to the output end of the second cylinder 411. A third fixing plate 413 is fixedly connected to the bottom of the second fixing plate 412. A moving rod 414 is symmetrically fixed to the top of the third fixing plate 413.

[0036] The bottom of the fixed base 42 has a hole that matches the output shaft of the first cylinder 43, and the output shaft of the first cylinder 43 passes through and slides up and down in the hole.

[0037] The top of the fixed seat 42 has a hole that matches the guide rod 45, and the surface of the guide rod 45 passes through and slides up and down in the hole. The four sets of guide rods 45 support the lifting seat 44, making the lifting seat 44 move up and down more stably. The surface of the moving rod 414 is slidably connected in the inclined groove 49.

[0038] In actual operation, when this device is used, the first servo motor 36 starts, driving the rotating shaft 34 to rotate. The gear 35, which is fixedly connected to the middle of the surface of the rotating shaft 34, rotates synchronously with the rotating shaft 34. The gear 35 meshes with the rack 37, which is fixedly connected to the left and right sides of the inner wall of the rectangular frame 31. According to the transmission principle of the gear 35 and rack 37, the rotation of the gear 35 is converted into its translational motion on the rack 37. Since the sliding sleeve 32 is slidably connected to the rectangular frame 31, and the first fixed frame 33 is fixed to the surface of the sliding sleeve 32, when the gear 35 moves along the rack 37, it drives the sliding sleeve 32, the first fixed frame 33, and the entire coating execution component connected to the first fixed frame 33 to slide left and right on the surface of the rectangular frame 31, realizing the movement of the coating component in the transverse direction of the screen. The hopper 39 is fixed on the front and rear sides inside the second fixed frame 38, and the discharge nozzles 311, which are equidistantly distributed at the bottom of the hopper 39, are used to output the coating. A flow controller is fixedly connected to the surface of the nozzle 311, allowing manual adjustment of the paint flow rate according to actual coating requirements. A second servo motor 312 is mounted on the front of the second mounting bracket 38 near the bottom. Its output shaft passes through a matching hole on the front of the second mounting bracket 38 and is rotatably connected within the hole. The output end is fixedly connected to the front end of the coating roller 313. When the second servo motor 312 starts, it drives the coating roller 313 to rotate. Since the coating roller 313 is located directly below the nozzle 311, the paint flowing from the nozzle 311 falls directly onto the rotating surface of the coating roller 313. As the coating roller 313 rotates, the paint is evenly coated onto the solar printing screen below it. A fixing block 314 is symmetrically fixed to the right side of the second mounting bracket 38 near the bottom, with the other end of the fixing block 314 connected to a scraper 315. After the coating roller 313 completes the paint coating, the scraper 315 immediately smooths the paint coated on the screen. The function of the doctor blade 315 is to scrape off excess coating on the screen, so that the coating forms a uniform and smooth coating on the screen, further improving the coating quality.

[0039] The first cylinder 43 is fixed to the bottom of the base 1. Its output shaft passes through a matching hole opened at the bottom of the fixed seat 42 and slides up and down within the hole. The output end is fixedly connected to the lifting seat 44. When the piston of the first cylinder 43 extends and retracts, it drives the lifting seat 44 to move up and down. The guide rods 45, which are symmetrically fixedly connected to the bottom of the lifting seat 44, pass through the matching hole opened at the top of the fixed seat 42 and slide up and down within the hole. The four sets of guide rods 45 provide stable support for the lifting seat 44, so that the lifting seat 44 remains stable during the up and down movement driven by the first cylinder 43, without shaking or shifting. Thus, the height of the solar printing screen fixed on the lifting seat 44 can be precisely adjusted according to the coating process requirements. The second cylinder 411 is fixed to the top left end of the lifting seat 44, and its output end is fixedly connected to the second fixed plate 412. When the second cylinder 411 is activated, the piston extends or retracts, causing the second fixed plate 412 to move left and right. The third fixed plate 413, which is fixedly connected to the bottom of the second fixed plate 412, moves synchronously with the second fixed plate 412. The moving rods 414, which are symmetrically fixedly connected to the top of the third fixed plate 413, also move accordingly. The end of the moving rod 414 slides in the inclined groove 49 opened near the left end of the top of the clamping block 48. The clamping block 48 slides symmetrically back and forth on the surface of the slide rod 47, which is fixedly connected to the inner side of the first fixed plate 46. When the moving rod 414 slides in the inclined groove 49, according to the guiding effect of the inclined groove 49, it will push the two clamping blocks 48 to move towards or away from each other along the slide rod 47. When the clamping blocks 48 move towards each other, the solar printing screen placed on the top of the lifting seat 44 can be clamped and fixed; when the clamping blocks 48 move away from each other, the screen is released, facilitating operations such as screen replacement.
