Description

Technical Field

[0001] The invention belongs to the technical field of coating and curing, and in particular relates to a scraping coating curing system and method. Background Art

[0002] The post-coating treatment process is a process for functionalizing the coating liquid film layer. The most representative post-coating treatment process is the UV curing process. The UV curing process is a cutting-edge application of photochemical reactions involving coating technology. Through UV irradiation of a certain intensity, it can instantly cure inks, coatings, glues and other related chemicals. Since its advent in 1960, with the rapid development of science and technology, the application field of UV curing technology has continued to expand, covering multiple industries such as automobiles, electronics, communications, aerospace, metals, glass and plastics. Thanks to its significant improvement in product quality and good environmental performance, the UV curing process has gradually replaced the traditional curing process at a rate of more than 10% per year, showing strong market potential.

[0003] However, in the implementation of the UV curing process, the UV light source is often set up as a separate working condition after the coating process. The UV light source is fixedly arranged, and the liquid film to be cured is sent into the irradiation range of the UV light source through a conveyor. After curing, it is taken out through the conveyor. This method causes the liquid film after coating to not cure quickly and in time, and the probability of the liquid film surface being micro-disturbed during the transmission process increases, affecting the uniformity of film formation. On the other hand, the current large-area UV light source is composed of multiple lamp bead arrays. The irradiation surface will produce light intensity deviations due to the density of the lamp beads, thereby affecting the final curing effect of the product (such as Figure 2 ). Similarly, conventional emission sources such as thermal radiation, electromagnetic field, gas, solid, liquid, etc. are usually arranged in an array of a large number of single emission units, such as thermal radiation lamp array, electromagnetic field emission head array, gas nozzle array, powder nozzle array, liquid atomization nozzle array. There are unavoidable gaps between each emission unit, resulting in uneven distribution of heat, electromagnetic and material emitted by the emission unit on the plane, affecting the final curing effect. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a scraping and curing system and method, which can achieve uniform and immediate post-processing of a liquid film.

[0012] Preferably, the reciprocating drive mechanism is a crank slider mechanism, a gear rack transmission mechanism, an eccentric wheel mechanism, a screw nut mechanism, a hydraulic cylinder mechanism, a cylinder mechanism, an electromagnetic drive mechanism or a belt pulley mechanism.

[0013] A scraping coating curing method, based on the scraping coating curing system as described above, comprises: The slurry is injected into the coating substrate at a position in front of the coating scraper, and the coating scraper is driven by the scraper driving mechanism to move forward along the x-axis direction to flatten the slurry. The emission source is driven by the horizontal driving mechanism to move forward along the x-axis direction, and the reciprocating driving mechanism is used to drive the emission source to reciprocate along the y-axis direction.

[0014] Preferably, the movement speed of the emission source in the x-axis direction is the same as the movement speed of the coating blade in the x-axis direction.

[0024] In the present invention, the front refers to the moving direction of the coating blade when coating the slurry.

[0025] The scraping and curing system described in the present invention includes: an emission source motion system and a substrate coating system; the substrate coating system includes: a coating substrate 21, a coating scraper 22 and a scraper driving mechanism; the emission source motion system includes an emission source 18, a horizontal driving mechanism 11 and a reciprocating driving mechanism 17.

[0026] The coating blade 22 and the emission source 18 are both disposed above the coating substrate 21 , and the emission source 18 is located behind the coating blade 22 ; the emission source 18 is composed of a plurality of emission units arranged in an array.

[0027] The scraper drive mechanism is used to drive the coating scraper 22 to perform linear motion along the x-axis direction; the horizontal drive mechanism 11 is used to drive the emission source 18 to perform linear motion along the x-axis direction; the reciprocating drive mechanism 17 is used to drive the emission source 18 to perform reciprocating motion along the y-axis direction. When the emission source 18 moves along the x-axis direction, it is always located behind the coating scraper 22, and has the same movement direction and speed as the coating scraper 22. The relative spatial position of the emission source 18 and the coating scraper 22 during the movement process is controlled to remain unchanged, and there is no collision between the emission source 18 and the coating scraper 22 during the movement process. During the movement of the coating scraper 22, the coating scraper 22 and the coating substrate 21 always maintain a constant gap, and the movement duration and movement displacement of the coating scraper 22 can be controlled as needed.

[0028] The present invention arranges the emission source 18 above the coating substrate 21, and the emission source 18 moves synchronously with the coating scraper 22, so that after the coating scraper 22 flattens the slurry to form a liquid film, the emission source 18 can be used to solidify the liquid film in time. There is no need to transfer the liquid film, and the post-processing process is entered in situ, which reduces the probability of the liquid film being micro-disturbed, reduces the instability of the liquid film, and improves the film forming efficiency and quality.

[0029] More importantly, the present invention is provided with a reciprocating drive mechanism 17 for driving the emission source 18 to perform reciprocating motion. While the horizontal drive mechanism 11 drives the emission source 18 to advance along the x-axis direction, the emission source 18 also performs reciprocating motion along the y-axis direction. The reciprocating motion in the y-axis direction and the linear motion in the x-axis direction are combined to form a sinusoidal motion path, so that the signal coverage range of the emission source 18 forms a sinusoidal motion path, which can reduce the uneven distribution of the emission source 18 signal caused by the gap between the emission units, so that the post-processing of the coated liquid film is more uniform.

[0030] Since a certain distance needs to be maintained between the emission source 18 and the liquid film to be solidified, when the material type and thickness of the product to be prepared change, the distance between the emission source 18 and the liquid film needs to be adjusted. For this reason, in the preferred embodiment of the present invention, a vertical drive mechanism 13 is also provided for driving the emission source 18 to move along the z-axis direction. The vertical drive mechanism 13 can control the height of the emission source 18 from the liquid film to adapt to different working conditions. When the position of the emission source 18 in the z-axis direction needs to be adjusted, it can be conveniently adjusted through the vertical drive mechanism 13 without interrupting the production rhythm, affecting production, and affecting production efficiency.

[0031] In some specific embodiments of the present invention, the emission source 18 is suspended above the coated substrate 21 without contact through the support truss 3. Specifically, the horizontal drive mechanism 11 is arranged on the support truss 3, and the reciprocating drive mechanism 17 is arranged on the output end of the horizontal drive mechanism 11. At the same time, the output end of the horizontal drive mechanism 11 is also provided with a first support rail 16, and the emission source 18 is slidably connected to the first support rail 16, and the output end of the reciprocating drive mechanism 17 is connected to the emission source 18. Therefore, when the horizontal drive mechanism 11 is working, its output end drives the reciprocating drive mechanism 17 and the emission source 18 to move forward along the x-axis direction, and at the same time, the reciprocating drive mechanism 17 drives the emission source 18 to reciprocate along the y-axis direction, and the first support rail 16 can play a role in supporting and guiding the emission source 18.

[0032] When the vertical driving mechanism 13 is provided, the vertical driving mechanism 13 can be provided on the output end of the horizontal driving mechanism 11, and the first supporting rail 16 and the reciprocating driving mechanism 17 can be provided on the output end of the vertical driving mechanism 13. Of course, the horizontal driving mechanism 11 can also be provided on the output end of the vertical driving mechanism 13, and the first supporting rail 16 and the reciprocating driving mechanism 17 can be provided on the output end of the horizontal driving mechanism 11. As long as the movement of the emission source 18 in the x-axis direction and the y-axis direction can be achieved at the same time.

[0033] In order to ensure the stability of the emission source 18 during movement, in some embodiments of the present invention, a balance rail 14 and a second support rail are provided. Specifically, the output end of the horizontal drive mechanism 11 is connected to a balance rail 14 arranged along the z-axis direction, and the balance rail 14 is slidably connected to a second support rail arranged along the y-axis direction, and the second support rail is arranged opposite to and parallel to the first support rail 16. One side of the emission source 18 is slidably connected to the first support rail 16, and the other side is slidably connected to the second support rail, thereby ensuring the stability of the emission source 18 when it reciprocates in the y-axis direction. At the same time, when the vertical drive mechanism 13 drives the emission source 18 to move in the z-axis direction, the balance rail 14 can support the other side of the emission source 18 and play a guiding role, thereby improving the stability of the emission source 18 during vertical movement and preventing the center of gravity from deviating.

[0034] The horizontal driving mechanism 11 in the present invention may adopt any driving mechanism that can provide linear motion, such as a screw-nut mechanism, without any particular limitation.

[0035] The reciprocating drive mechanism 17 in the present invention can be a crank slider mechanism, a gear rack transmission mechanism, an eccentric wheel mechanism, a screw nut mechanism, a hydraulic cylinder mechanism, a cylinder mechanism, an electromagnetic drive mechanism or a belt pulley mechanism, as long as it can provide reciprocating motion.

The first slider is connected to the first screw, and the output end of the first stepper motor is connected to one end of the first screw. The first screw is driven to rotate by the first stepper motor, thereby driving the first slider to perform linear motion.

[0047] The vertical drive mechanism 13 is a screw-nut mechanism, including a second screw, a second slider and a second stepper motor. The second slider is connected to the second screw, and the output end of the second stepper motor is connected to one end of the second screw. The second stepper motor drives the second screw to rotate, thereby driving the second slider to perform linear motion.

[0048] The reciprocating drive mechanism 17 is an eccentric wheel mechanism, that is, an eccentric wheel reciprocating motion motor. The scraper drive mechanism is a motor. The first support rail 16 is arranged along the y-axis direction, and the second support rail is arranged opposite to and parallel to the first support rail 16; the balance rail 14 is arranged along the z-axis direction and opposite to and parallel to the second lead screw.

[0049] The coating blade 22 and the emission source 18 are both disposed above the coating substrate 21, and the emission source 18 is located behind the coating blade; the emission source 18 is composed of a plurality of emission units arranged in an array.

[0050] The horizontal driving mechanism 11 is installed on the supporting truss 3, and the vertical driving mechanism 13 and the balancing guide rail 14 are connected to the first slider of the horizontal driving mechanism 11 through the structural connector 12. The reciprocating driving mechanism 17 and the first supporting guide rail 16 are connected to the second slider of the vertical driving mechanism 13 through the first fixing plate 15, and the second supporting guide rail is connected to the balancing guide rail 14 through the second fixing plate.

[0051] The first stepper motor drives the emission source 18 on the first slider to perform scanning motion along the x-axis direction on the coated substrate through the first lead screw. The movement speed of the emission source 18 is controlled to be equal to the movement speed of the coating scraper through the first stepper motor. The second stepper motor drives the emission source 18 on the second slider to move in the z-axis direction through the second lead screw, thereby adjusting the height of the emission source 18.

[0053] In this embodiment, the freedom of the emission source 18 in three directions is realized through the cooperation of the horizontal drive mechanism 11, the reciprocating drive mechanism 17, and the vertical drive mechanism 13. The emission source 18 is controlled by the horizontal drive mechanism 11 to follow the movement of the coating scraper. The liquid film formed after the coating scraper 22 flattens the slurry immediately enters the irradiation area of ​​the emission source 18, so that the liquid film is immediately solidified and uniformly solidified into a film during the post-processing process of the emission source 18. The reciprocating drive mechanism 17 can eliminate the mesh uneven irradiation caused by the emission unit array of the emission source 18 through lateral vibration during the scanning process, which can effectively improve the uniformity of coating and film making.
