Description

Technical Field

[0001] The invention relates to the technical field of film-coated polymer material sublimation, in particular to a film-coated polymer material sublimation device. Background Art

[0002] The coating material is generally heated to make the surface components evaporate in the form of atomic groups or ions, and settle on the surface of the substrate to form a thin film through the film forming process. The film forming process is: scattered points - island structure - vagal structure - layered growth. The existing sublimation device has the following defects during use:

[0003] First, when polymer materials are sublimated, due to the temperature difference between the film surface and the substrate, the film will be affected by thermal stress during the deposition process. The internal stress generated inside the film will have a negative impact on the physical properties and performance of the film, thus causing the film to crack.

[0004] Secondly, existing sublimation devices are mostly assembled and connected by flanges, and the single-layer flange structure without sealing protection cannot guarantee the sealing of the sublimation device, which is very likely to cause leakage of polymer materials in seamless pipes and loss of high-temperature heat;

[0005] Finally, the gas generated by the sublimation device after evaporating the coating polymer material needs to rely on the gas's own fluidity to achieve natural transportation and sedimentation. Not only is the coating efficiency low, but the disordered sedimentation cannot guarantee the saturation and uniformity of the coating process. Summary of the invention

[0054] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0055] Reference Figure 1-Figure 8 A coating polymer material sublimation device includes a seamless tube 1, on which a first fixing component 2 and a second fixing component 3 are arranged. The first fixing component 2 is matched with one end of the seamless tube 1, and the second fixing component 3 is matched with the other end of the seamless tube 1.

[0056] In some embodiments, the first fixing assembly 2 includes an upper flange 201, a material door base 202 including a door support plate, a pressure plate base 203, a spin plate 204, an adjustment block 205, a handle 206, a door hinge plate 207, a material door 208 and an arc cover 209, and each component is specifically arranged as follows:

[0057] Reference Figure 1 and Figure 2 The upper flange 201 is fixedly connected to one end of the seamless pipe 1. The fixing method is one of welding or bolting. When welding is adopted, the upper flange 201 is ensured to be integrally arranged with the seamless pipe 1. When bolting is adopted, the upper flange 201 is combined with the seamless pipe 1 when it is assembled, which increases the flexibility of the installation of the upper flange 201 to enhance its adaptability.

[0058] Reference Figure 1 and Figure 2 The material door base 202 is fixedly connected to one side of the upper flange 201 by flat head screws, and threaded holes used in conjunction with the flat head screws are provided on the material door base 202 and the upper flange 201. It should be noted that: the door support plate is installed on the material door base 202 by hexagon socket bolts, gaskets and spring washers. The gaskets and the spring washers are provided with holes corresponding to the hexagon socket bolts. The material door base 202 and the door support plate are provided with threaded holes corresponding to the hexagon socket bolts. The spring washer is located above the gasket. Since the spring washer has pre-tension, after the hexagon socket bolt presses the spring washer, under the action of pre-tension and friction, the hexagon socket bolt will no longer loosen. Moreover, the diameter of the gasket located below the spring washer is larger than that of the spring washer, which helps to increase the force-bearing area of ​​the hexagon socket bolt and the spring washer. The advantages of the shape setting of the gasket and its setting position are the same as those of other components except the gasket.

[0059] Reference Figure 1 and Figure 2 The pressing plate base 203 is fixedly connected to the other side of the upper flange 201 by flat head screws, and the structural tightness of the upper flange is enhanced by arranging the material door base 202 and the pressing plate base 203;

[0060] Reference Figure 1 and Figure 2The spinning plate 204 is rotatably installed on the pressure plate base 203 through a rotating shaft, a gasket, a hexagon socket bolt, a locking nut and a gasket. The rotating shaft is set so that the spinning plate 204 can be rotated, and the spinning plate 204 is driven to rotate by the hexagon socket bolt. When the rotating shaft and the hexagon socket bolt are used, a gasket structure is provided in combination. The gasket structure can ensure the tightness of the hexagon socket bolt and the rotating shaft. It should be noted that: a storage groove for sliding the hexagon socket bolt is provided on the rotating shaft, and the locking nut and the gasket are located at the bottom end of the pressure plate base 203. The locking nut and the hexagon socket bolt are used in conjunction to strengthen the tightness between the spinning plate 204 and the pressure plate base 203.

[0061] Reference Figure 1 and Figure 2 The adjusting block 205 is arranged on the spinning plate 204 by two screws, two hexagon socket bolts, two washers and two spring washers. It should be noted that the two hexagon socket bolts, two washers and two spring washers are arranged in a matching manner, and the two screws are arranged at the inner side of the two hexagon socket bolts. The arrangement of the washers and the spring washers can prevent the hexagon socket bolts from loosening. The handle 206 is arranged in a matching manner on the spinning plate 204;

[0062] Reference Figure 1 and Figure 2 , the door hinge plate 207 is installed on the material door base 202 through the door support plate and the pin shaft, and the material door 208 is fixedly installed on the door hinge plate 207 through a gasket, a spring washer group and an inner hexagonal bolt. The setting of the gasket and the spring washer group can prevent the inner hexagonal bolt from loosening, and the material door 208 is hingedly installed by utilizing the connection relationship between the door hinge plate 207 and the material door base 202. It should be noted that: the pin shaft is installed on the door support plate through a retaining spring, and a movable long hole for sliding the pin shaft is opened on the door hinge plate 207, so that the door hinge plate 207 can rotate based on the pin shaft, and the retaining spring can prevent the door hinge plate 207 on the pin shaft from axial movement, so that the material door 208 fixedly connected to the door hinge plate 207 can be manually deflected and adjusted;

[0063] Reference Figure 1 and Figure 2 The arc cover 209 is installed on the material door 208 through bolts and a hand wheel. The material door 208 located between the above two is pressed and fixed by the spinning plate 204 and the pressure plate base 203, which helps to ensure the sealing and stability of the connection between the material door 208 and the upper flange 201. The material door 208, the arc cover 209 and the hand wheel are all provided with threaded holes corresponding to the bolts, so that the arc cover 209 is installed on the material door 208. When the hand wheel is installed on the arc cover 209, the setting of the hand wheel helps to improve the convenience of the staff in operating the material door 208 to open and close.

[0064] In some embodiments, the second fixing assembly 3 includes a bottom cover 301 and a standard part 302. Further, the bottom cover 301 and the standard part 302 are arranged such that the bottom cover 301 is mounted on the other end of the seamless pipe 1, and the standard part 302 is mounted on the bottom cover 301. The other end of the seamless pipe 1 can be normally closed through the bottom cover 301.

[0065] Based on the setting of the seamless pipe 1, in order to provide a working space for the sublimation operation of the coated polymer material, a working pipe 4 and a cover plate 5 are also provided on the seamless pipe 1. The working pipe 4 is fixedly connected to the seamless pipe 1, and one end of the cover plate 5 is pin-mounted on the working pipe 4, and the other end of the cover plate 5 is bolted to the working pipe 4. It should be noted that the bolts used by the working pipe 4 and the cover plate 5 are matched with gaskets to improve the tightness between the working pipe 4 and the cover plate 5. The working pipe 4 and the cover plate 5 are both located on one end of the seamless pipe 1 for setting the first fixing component 2;

[0066] An insulating cavity 14 for filling insulating materials is provided between the working tube 4 and the seamless tube 1. The insulating materials in the insulating cavity 14 can avoid scalding accidents when taking the seamless tube 1, which helps to improve the safety of the sublimation device.

[0067] Based on the setting of the seamless pipe 1, in order to realize the separate operation of heating sublimation and sedimentation collection of the coated polymer material, a heating cavity 6 and a sedimentation cavity 7 are also provided on the seamless pipe 1. The heating cavity 6 and the sedimentation cavity 7 are symmetrically opened in one end of the seamless pipe 1 for setting the first fixing component 2, so that the input of the sublimated coated polymer material and the removal of the coated finished product can be taken out through one end of the seamless pipe 1, which helps to improve the convenience of the staff in taking the operation;

[0068] An electric heating wire 15 is provided in the wall of the heating cavity 6, and the electric heating wire 15 is a multi-layer square ring structure, which helps to improve the heating uniformity of the coating polymer material by the electric heating wire 15. The electric heating wire 15 is provided with an internal power supply located in the working tube 4, and the internal power supply is provided with an on-off switch;

[0069] Based on the setting of the seamless pipe 1, in order to connect the heating cavity 6 and the sedimentation cavity 7, a U-shaped connecting pipe 8 is also provided on the seamless pipe 1. The U-shaped connecting pipe 8 is fixedly connected between the heating cavity 6 and the sedimentation cavity 7, and the U-shaped connecting pipe 8 is located in the seamless pipe 1, so that the gas generated after the sublimation of the coating polymer material can flow into the sedimentation cavity 7 through the U-shaped connecting pipe 8;

[0070] Based on the setting of the seamless pipe 1, in order to achieve communication with the U-shaped connecting pipe 8 when the internal pressure of the heating cavity 6 changes, and not communicating with the U-shaped connecting pipe 8 when the internal pressure of the heating cavity 6 remains unchanged, a pressure valve 9 is also provided on the seamless pipe 1. The pressure valve 9 is fixedly arranged between the U-shaped connecting pipe 8 and the heating cavity 6. Through the setting of the pressure valve 9, when the coated polymer material sublimates and generates gas, the pressure inside the heating cavity 6 will change. When the internal pressure of the heating cavity 6 increases, the pressure valve 9 will no longer close the U-shaped connecting pipe 8. It should be noted that when the coated polymer material is heated and does not sublimate to generate gas, the pressure valve 9 closes the U-shaped connecting pipe 8 and the heating cavity 6, so as to avoid the electric heating wire 15 from losing heat due to the opening of the U-shaped connecting pipe 8, which affects the sublimation efficiency of the coated polymer material.

[0071] Based on the setting of the seamless pipe 1, in order to achieve heat preservation of the gas flowing in one side of the heating cavity 6 of the U-shaped connecting pipe 8, a heat preservation cavity 10 is also provided on the seamless pipe 1. The heat preservation cavity 10 is opened on one side of the U-shaped connecting pipe 8 close to the heating cavity 6, and the heat preservation cavity 10 is filled with heat preservation material. The setting of the heat preservation material can prevent the gas generated after the sublimation of the polymer material from cooling during the transportation process, which helps to prevent the gas generated after the sublimation of the polymer material from condensing in advance;

[0072] Based on the setting of the seamless tube 1, in order to adjust the temperature difference between the collecting substrate 12 and the thin film formed on the surface of the collecting substrate 12, a placing plate 11, a collecting substrate 12, a resistance block 13, a temperature controller 17 and a heating plate 16 are also provided on the seamless tube 1. For details, refer to the attached manual. Figure 8 , further, the placement plate 11 is integrally connected to the inner wall of the sedimentation chamber 7, the collecting substrate 12 is movably placed on the placement plate 11, the abutment block 13 is fixedly connected to the collecting substrate 12, a heating plate 16 is fixedly mounted on the collecting substrate 12, and a temperature controller 17 for adjusting the temperature of the heating plate 16 is fixedly mounted on the placement plate 11. It should be noted that: the temperature controller 17 and the heating plate 16 are equipped with a built-in power supply located in the working tube 4, the temperature controller 17 is used to sense the temperature of the outer end of the collecting substrate 12 and then control the heating temperature of the heating plate 16, which helps to reduce the temperature difference between the collecting substrate 12 and the film, thereby reducing the thermal stress generated in the film during the deposition process, and helps to avoid the negative impact of thermal stress on the film causing cracking;

[0073] Based on the setting of the seamless tube 1, in order to achieve uniform sedimentation of the coated polymer material on the collecting substrate 12, an auxiliary mechanism is also provided on the seamless tube 1, and the auxiliary mechanism is provided in the U-shaped connecting tube 8 and the sedimentation cavity 7, and the auxiliary mechanism is used to control the flow rate of the airflow in the U-shaped connecting tube 8 and the sedimentation cavity 7;

[0074] In some embodiments, the auxiliary mechanism includes a buffer cover 18, a transition duct 19, a diffuser cover 20, a discharge plate 21, a fan 22, a spiral blade 23, a guide hole 24, a guide port 25, a first guide plate 26 and a second guide plate 27, and each component is specifically arranged as follows:

[0075] Reference Figure 6 , the buffer cover 18 is fixedly connected to the settling chamber 7, and the buffer cover 18 is arranged corresponding to the U-shaped connecting pipe 8, the transition pipe 19 is fixedly connected to the buffer cover 18, the diffusion cover 20 is fixedly connected to the transition pipe 19, and the discharge plate 21 is fixedly connected to the end of the diffusion cover 20 away from the transition pipe 19;

[0076] The buffer cover 18 and the diffuser cover 20 are funnel structures with openings facing each other, and the discharge plate 21 is concentrically connected to one end of the diffuser cover 20 away from the transition pipe 19;

[0077] The buffer cover 18, the transition pipe 19 and the diffusion cover 20 are integrally formed into an hourglass structure, so that when the gas flows from the U-shaped connecting pipe 8 to the buffer cover 18, the transition pipe 19 and the diffusion cover 20 in sequence, the gas will first enter the large space from the small space, then enter the small space through the large space, and finally enter the large space through the small space, so that the gas undergoes multiple diffusion and concentration, thereby realizing gas expansion, so that the gas does external work, and the internal energy is converted into mechanical energy. Under this action, the internal energy is reduced and the mechanical energy is increased. According to the law of conservation of energy, the internal energy of the gas is reduced. As long as the physical state remains unchanged, the relative distance between molecules remains unchanged, and the molecular potential energy remains unchanged, the change in internal energy, that is, the change in molecular kinetic energy, the reduction in internal energy, the weakening of gas molecular motion, and the reduction in molecular kinetic energy, thereby reducing the temperature of the gas and helping to improve the sedimentation efficiency of the gas;

[0078] Based on the setting of the hourglass structure, the present invention also discloses a structure that can generate an inlet airflow, which is composed of a fan 22 and a spiral blade 23. The fan 22 is fixedly installed in the transition pipe 19. The fan 22 is equipped with an internal power supply located in the working pipe 4. The internal power supply is equipped with an on-off switch. Through the buffer cover 18, the transition pipe 19 and the diffusion cover 20, it should be noted that the main body of the fan 22 is composed of fan blades, a fan shaft, a motor and a fan bracket. The fan bracket is the support and guide part of the fan 22. The fan bracket is a circular frame structure corresponding to the transition pipe 19, and an air guide port is opened on the fan bracket;

[0079] The spiral blade 23 is disposed in the U-shaped connecting pipe 8 through the fan shaft of the fan 22. The spiral blade 23 is used to spirally transport the gas in the U-shaped connecting pipe 8 on one side of the sedimentation chamber 7, which helps to improve the flow efficiency of the gas in the U-shaped connecting pipe 8.

[0080] A guide port 25 corresponding to the spiral blade 23 is provided between the buffer cover 18 and the U-shaped connecting pipe 8. A staggered first guide plate 26 and a second guide plate 27 are fixedly connected in the buffer cover 18, and the first guide plate 26 and the second guide plate 27 are arranged in opposite directions.

[0081] It should be noted that: by the inclined arrangement of the guide port 25, the first guide plate 26 and the second guide plate 27, the gas will collide with the guide port 25, the first guide plate 26 and the second guide plate 27 when passing through the guide port 25, the first guide plate 26 and the second guide plate 27, so that the gas is deflected multiple times, thereby slowing down the flow rate of the gas and preventing the gas from directly contacting the fan 22 and causing the fan 22 to be compressed and damaged;

[0082] Please refer to the instruction manual for details Figure 6 The guide holes 24 are evenly distributed in the discharge plate 21 in the circumferential direction, and the gas in the diffuser 20 moves through the evenly distributed guide holes 24 so that the airflow is dispersed and moves to avoid concentration;

[0083] In some embodiments, the guide hole 24 includes a first vertical section 28, a first inclined section 29, a second vertical section 30, a second inclined section 31, a third vertical section 32 and a diffuser section 33 connected in sequence, and each component is specifically arranged as follows:

[0084] Reference Figure 7 The first vertical section 28 is connected to the upper end of the first inclined section 29. The vertical arrangement of the first vertical section 28 allows the gas in the diffuser 20 to directly enter the guide hole 24, which helps to improve the efficiency of the gas entering the guide hole 24.

[0085] Under the inertial impact of the gas, since the angle between the first vertical section 28 and the first inclined section 29 is an obtuse angle, the gas will collide with the inner wall of the first inclined section 29 under the guidance of the first vertical section 28, so that the gas flow rate is reduced;

[0086] The second vertical section 30 is connected to the upper end of the first inclined section 29, and the angle between the first inclined section 29 and the second vertical section 30 is an obtuse angle. The second inclined section 31 is connected to the upper end of the second vertical section 30, and the angle between the second vertical section 30 and the second inclined section 31 is an obtuse angle. The first inclined section 29 and the second inclined section 31 are opened in opposite directions. The gas will collide with the inner wall of the second inclined section 31 under the guidance of the second vertical section 30. The first vertical section 28 and the first inclined section 29 can further reduce the gas flow rate, so that the gas discharge flow rate is slower and more natural, avoiding the gas flow rate being too fast to collide with the collection substrate 12 and causing backflow, which helps to ensure the stability of the gas during sedimentation.

[0087] The third vertical section 32 is connected to the second inclined section 31, and the angle between the second inclined section 31 and the third vertical section 32 is an obtuse angle. The diffusion section 33 is connected to the upper end of the third vertical section 32. The diffusion section 33 is a trumpet-shaped structure. The gas can be guided to the diffusion section 33 through the third vertical section 32. The gas is guided by the diffusion section 33 and sinks to the collection substrate 12, thereby increasing the coverage area of ​​the gas on the collection substrate 12. The gas is put into the collection substrate 12 through a plurality of guide holes 24, which helps to improve the uniformity of the gas film after it is formed.

[0088] It should be noted that the specific models and specifications of the air pressure valve 9, the electric heating wire 15, the heating plate 16, the temperature controller 17 and the fan 22 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated. The above-mentioned gas specifically refers to the gas generated after the sublimation of the coated polymer material. When the device is operating, the device is provided with one end of the first fixed component 2 placed downward.

[0089] The present invention can be explained by the following operation mode:

[0090] Rotate the spinning plate 204, open the material door 208 and the cover plate 5, place the coating polymer material to be sublimated in the heating chamber 6, close the cover plate 5, and close the material door 208;

[0091] The electric heating wire 15 and the fan 22 are started, and the electric heating wire 15 heats the coating polymer material. The gas generated after the coating polymer material sublimates reaches the required pressure state inside the heating cavity 6, and the pressure valve 9 is opened, and the gas enters the U-shaped connecting pipe 10;

[0092] The fan 22 drives the spiral blade 23 to rotate through the fan shaft, so as to spirally transport the gas. The gas enters the buffer cover 18 under the guidance of the guide port 25. Through the arrangement of the first guide plate 26 and the second guide plate 27, the gas performs multiple deflection motions in the buffer cover 18 along a Z-shaped trajectory to achieve deceleration.

[0093] The gas in the buffer cover 18 is transported by the fan 22 so that the gas enters the diffusion cover 20 through the transition pipe 19. Figure 6 With attached Figure 7 First, the gas enters the first inclined section 29 through the first vertical section 28, then the gas enters the second vertical section 30 through the first inclined section 29, then the gas enters the second inclined section 31 through the second vertical section 30, then the gas enters the third vertical section 32 through the second inclined section 31, and finally, the gas enters the diffusion section 33 through the third vertical section 32. Because the opening suddenly becomes larger, the pressure becomes smaller and the flow rate decreases, so that the gas flows to the collection substrate 12 through the diffusion section 33 during the slow movement;

[0094] The temperature in the settling section 7 is sensed by the temperature controller 17 , and the heating plate 16 is started. The heating plate 16 can heat the collecting substrate 12 , so as to avoid a large temperature error between the collecting substrate 12 and the coating film.

[0095] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
