Description

Technical Field

[0001] This utility model relates to the field of manufacturing equipment technology in the photovoltaic industry, and in particular to a scraper mechanism for laser printing substrates. Background Technology

[0002] The coating process on the laser printing substrate is one of the key steps in the laser printing process. It involves uniformly applying a specific paste or coating onto the substrate to ensure the smooth progress of the subsequent laser printing process. During the coating process, a special doctor blade mechanism is usually used to scrape off excess paste to ensure the uniformity of the coating. Inevitably, some paste will remain on the doctor blade during the coating process. If this residual paste is not recovered in time, it will not only waste raw materials, but may also affect the normal use of the doctor blade due to the drying and clumping of the paste, thus affecting the coating quality.

[0003] The existing scraper mechanism lacks effective recycling measures, making it difficult to recycle the remaining slurry on the scraper in a timely manner. Moreover, existing equipment usually requires shutdown to recycle the slurry on the scraper, which affects production continuity and efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of existing scraper mechanisms that lack a recycling device, this utility model provides a scraper mechanism for laser printing substrates.

[0005] The technical solution of this utility model is as follows: A scraper mechanism for laser printing substrate includes a frame, a lifting mechanism, a mounting frame, a motor, a fixing plate, a scraper, a second cylinder, and a scraper blade. The lifting mechanism is located at the rear of the frame, and the mounting frame is located on the lifting mechanism. A motor is mounted on one end of the mounting frame, and two fixing plates are located on the output shaft of the motor. One of the fixing plates is connected to the output shaft of the motor, and two scrapers are located between the two fixing plates. The two fixing plates are fixed together by bolts to fix the scraper blade. A second cylinder is located at the front of the frame, and a scraper blade is located on the upper side of the second cylinder. A scraping opening is opened in the middle of the scraper blade.

[0006] In one embodiment, the lifting mechanism includes a first cylinder and a sliding frame. The first cylinder is located at the rear of the frame, and the piston of the first cylinder is connected to the mounting frame. Two sliding frames are located on the lower side of the mounting frame, and the sliding frames are slidably connected to the frame.

[0007] In one embodiment, a rubber strip is also included, with the scraping opening of the scraper having a rubber strip.

[0008] In one embodiment, a pressure sensor and an adjustment mechanism are also included, with the pressure sensor connected between the sliding frame and the mounting frame, and the adjustment mechanism provided between the mounting frame and the pressure sensor.

[0009] In one embodiment, the adjustment mechanism includes a bolt and an elastic element, with the bolt threaded onto the mounting bracket and the elastic element connecting the bolt and the pressure sensor.

[0010] In one embodiment, a collection frame is also included, which is slidably mounted on the frame and located directly below the scraper.

[0011] The present invention has the following advantages: 1. The present invention achieves rapid switching between the upper and lower scrapers by rotating the fixed plate driven by the motor. If the upper scraper accumulates slurry during the coating process, it can be immediately switched to the lower scraper to continue working. At the same time, the original upper scraper is cleaned, avoiding downtime and waiting, and significantly improving production efficiency.

[0012] 2. This utility model, through the design of a pressure sensor, can monitor the downward pressure of the scraper in real time. By cooperating with the bolt and the elastic element, the compression of the elastic element can be adjusted, and the scraper pressure can be dynamically adjusted to ensure that the scraper is subjected to uniform force on both sides, thereby improving the flatness and consistency of the coating.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] A squeegee mechanism for laser printing substrates, such as Figures 1-6As shown, the system includes a frame 1, a lifting mechanism, a mounting frame 4, a motor 5, a fixing plate 6, a scraper 7, a second cylinder 8, and a scraper blade 9. The lifting mechanism is located at the rear of the frame 1, and the mounting frame 4 is mounted on the lifting mechanism. The motor 5 is mounted on one end of the mounting frame 4. Two fixing plates 6 are located on the output shaft of the motor 5, one of which is connected to the output shaft of the motor 5. Two scrapers 7 are located between the two fixing plates 6. The two fixing plates 6 are fixed together by bolts 11, which also fix the scraper blade 7. The second cylinder 8 is located at the front of the frame 1, and a scraper blade 9 is located on the upper side of the second cylinder 8. The scraper blade 9 has a scraping opening in the middle. When the piston of the second cylinder 8 extends, the scraping opening of the scraper blade 9 contacts the side of the lower scraper blade 7.

[0022] In use, the upper scraper 7 performs the coating work. When there is too much slurry remaining on the upper scraper 7, the motor 5 drives the fixing plate 6 and the scraper 7 on it to rotate, which exchanges the positions of the upper and lower scrapers 7. The original lower scraper 7 performs the coating work. At this time, the second cylinder 8 drives the scraper 9 to rise. The scraper 9 scrapes off the slurry on the original upper scraper 7, thus simultaneously performing the coating work and cleaning the scraper 7. When it is necessary to replace the scraper 7, the lifting mechanism drives the mounting frame 4 and the motor 5 and scraper 7 on it to rise, remove the fixing plate 6 on one side, replace the scraper 7, and then reinstall the fixing plate 6. The lifting mechanism drives the scraper 7 to reset.

[0023] like Figure 4 As shown, the lifting mechanism includes a first cylinder 2 and a sliding frame 3. The first cylinder 2 is located on the rear side of the frame 1. The piston of the first cylinder 2 is connected to the mounting frame 4. Two sliding frames 3 are located on the lower side of the mounting frame 4. The sliding frames 3 are slidably connected to the frame 1. By extending and retracting the piston of the first cylinder 2, the mounting frame 4 and its motor 5 and scraper 7 can be driven to move up and down, which facilitates the replacement of the scraper 7. The sliding frame 3 is slidably connected to the frame 1, which ensures the stability and guidance of the mounting frame 4 during the lifting process, making the lifting movement more stable and accurate.

[0024] like Figure 3 As shown, it also includes a rubber strip 91. The scraping opening of the scraper 9 is provided with a rubber strip 91. The rubber strip 91 has a certain elasticity and softness. When the scraper 9 scrapes the slurry on the scraper 7, the rubber strip 91 can better fit the surface of the scraper 7, avoiding direct contact between the scraper 9 and the scraper 7 and causing damage to the surface of the scraper 7.

[0025] like Figure 4 and Figure 5As shown, it also includes a pressure sensor 10 and an adjustment mechanism. The pressure sensor 10 is connected between the sliding frame 3 and the mounting frame 4. An adjustment mechanism is provided between the mounting frame 4 and the pressure sensor 10. The pressure sensor 10 is used to detect the downward pressure of the doctor blade 7 during the coating process. When the pressure is abnormal, it can be adjusted in time through the adjustment mechanism to avoid affecting the printing quality and the service life of the doctor blade 7 due to excessive or insufficient pressure.

[0026] like Figures 5-6 As shown, the adjustment mechanism includes a bolt 11 and an elastic element 12. The mounting bracket 4 is threaded with a bolt 11, and an elastic element 12 is connected between the bolt 11 and the pressure sensor 10. When the pressure sensor 10 detects an abnormal pressure, the bolt 11 can be used to adjust the compression degree of the elastic element 12, thereby adjusting the force of the scraper 7 during coating, so that the scraper 7 is subjected to uniform force on both sides, ensuring the flatness and quality of the coating.

[0027] like Figure 1 As shown, it also includes a collection frame 13. The collection frame 13 is slidably provided on the frame 1. The collection frame 13 is located directly below the scraper 9. The collection frame 13 is used to collect the slurry scraped off the scraper 7 by the scraper 9, to prevent the slurry from falling randomly, to keep the working environment clean, and to facilitate the centralized processing of the scraped slurry.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
