Description

Technical Field

[0001] The present invention belongs to the technical field of thin film coating, and particularly relates to a thin film coating mechanism for electronic ceramic slurry. Background Art

[0002] Electronic ceramics (such as lanthanum lead zirconate titanate PLZT, alumina, etc.) are widely used in fields such as capacitors, sensors, and microelectronic devices due to their excellent dielectric, piezoelectric, and energy storage properties. With the advancement of technologies such as 5G communication and new energy storage, the market demand for highly uniform ceramic films has increased sharply. Such films need to uniformly attach ceramic slurry to the surface of the substrate through a coating process and then form a dense structure through sintering.

Therefore, an institution that can be applied to material verification experiments and in - process inspection is needed to avoid material waste and manpower waste caused by using large coating machines. Thus, a thin film coating mechanism for electronic ceramic slurry is proposed. Summary of the Invention

Detailed implementation manners

[0028] In order to make the objectives, technical solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0029] Referring to Figure 1-7 , an electronic ceramic slurry film coating mechanism is proposed in an embodiment of the present invention, including a working platform 1. Fixed plates 2 are installed at the four corners of the top of the working platform 1. Two fixed plates 2 on the same side are fixedly connected with sliding rods 4. A moving seat 5 is slidably connected to the sliding rods 4. A collection box 6 is arranged on the left side of the bottom of the working platform 1 for collecting excess slurry. A collection groove opened on the working platform 1 is arranged above the collection box 6. A material containing shell 10 is arranged between the two moving seats 5. A discharge port 71 is opened at the bottom of the material containing shell 10. A discharge plate 7 is rotatably connected in the discharge port 71. A flattening piece 72 is installed at the bottom of the material containing shell 10 for flattening the slurry. Avoidance grooves 8 are opened on the front and rear sides of the top of the working platform 1. A number of vacuum adsorption holes 9 are evenly arranged on the working platform 1 for adsorbing the film to be coated. A speed change component is arranged in the moving seat 5.

[0030] The speed-changing assembly includes a rotating shaft 51 rotatably connected to the moving seat 5 and a gear groove 54 formed at the top of the sliding rod 4. The rotating shaft 51 includes a push-pull rod body and a main rod body. The push-pull rod body extends out of the moving seat 5 and is slidably connected to the main rod body. One end of the push-pull rod body close to the main rod body is polygonal and is snap-connected, so as to ensure the linkage between the rotating push-pull rod body and the main rod body of the rotating shaft 51;

[0031] A first gear 52 is fixedly connected to the rotating shaft 51. A second gear 53 located on the rotating shaft 51 is installed on the side of the first gear 52. A first rack 55 is installed at the bottom of the cavity of the gear groove 54. The sizes of the first gear 52 and the first rack 55 are both less than half of the gear groove 54. The first rack 55 and the first gear 52 can be disengaged and meshed. A shaft body 50 is rotatably connected in the moving seat 5. A third gear 57 is connected to the shaft body 50. A sleeve 56 is slidably connected in the third gear 57. A top contact rod 58 is installed on the side of the sleeve 56. A receiving groove 59 is formed in the shaft body 50 and the third gear 57. A limiting piece 513 is slidably connected in the receiving groove 59. An extrusion rod 512 is connected in the middle of the limiting piece 513. A first extrusion spring 510 is fixedly connected to the bottom of the extrusion rod 512. A triangular groove 514 is formed at a position on the inner wall of the sleeve 56 that is adapted to the receiving groove 59. Through the speed-changing assembly, the opening and closing size of the discharge plate 7 can be flexibly changed according to the moving speed of the moving seat 5, thereby ensuring that the amount of discharged material will not cause uneven coating due to too little discharge when moving too fast.

[0032] The top contact rod 58 is slidably connected to the moving seat 5 and the material containing shell 10. Openings matching the sliding rod 4 are formed on both sides of the moving seat 5.

[0033] A discharge control assembly is arranged on the material containing shell 10. The discharge control assembly includes a cavity 121 formed in the material containing shell 10. A pressure-bearing platform 123 is slidably connected to the inner wall of the cavity 121. A second return spring 122 is fixedly connected to the top of the pressure-bearing platform 123. A top contact groove 124 is formed in the pressure-bearing platform 123. The groove wall of the top contact groove 124 contacts the top contact rod 58. A second rack 127 is fixedly connected to the bottom of the pressure-bearing platform 123. Pin-connected rods 125 are fixedly connected to both sides of the discharge plate 7. A fourth gear 126 is fixedly connected to the pin-connected rods 125. The discharge control assembly can accurately control the opening and closing of the discharge plate 7 according to the moving state of the moving seat 5, and further control the discharge amount of the slurry.

[0034] The discharge plate 7 is rotatably connected to the material containing shell 10 through the pin-connected rods 125. The fourth gear 126 meshes with the second rack 127. The top contact groove 124 is a groove with a triangular cross-section. A hole for the second rack 127 to move is formed in the material containing shell 10. A limiting strip is fixedly connected to the inner wall of the sleeve 56. A limiting groove matching the limiting strip is formed on the third gear 57.

[0035] A straightening component is provided at the bottom of the moving seat 5. The straightening component includes a bevel gear ring 111 fixed on the shaft body 50. A first bevel gear 112 is meshed and connected to the bevel gear ring 111. The bottom of the first bevel gear 112 is connected to a transmission rod 115 rotatably connected to the moving seat 5. The bottom of the transmission rod 115 is fixedly connected to a second bevel gear 119. A fixed frame 113 is fixedly connected to the bottom of the moving seat 5. A support frame 114 is fixedly connected to the side wall of the fixed frame 113. A number of transmission rods 1111 are rotatably connected in the support frame 114. One end of the transmission rod 1111 closer to the inside protrudes out of the support frame 114 and is fixedly connected to a third bevel gear 1110. A roller 116 is fixedly connected to each of the transmission rods 1111. The same friction belt 117 is installed on the outer side of the roller 116. A moving table 1113 is slidably connected to the bottom of the fixed frame 113. A bolt 1114 threadedly connected to the moving table 1113 and rotatably connected to the fixed frame 113. The moving table 1113 is connected to a lower support plate 118 located below the support frame 114. The straightening component can straighten the thin film during the coating process to prevent the thin film from wrinkling, especially in the adsorption area, reducing the occurrence of depressions in the adsorption area, so that the slurry accumulates in the depressions.

[0036] The third bevel gear 1110 is meshed with the second bevel gear 119. The bottom of the friction belt 117 protrudes from the bottom of the support frame 114. The bottom of the support frame 114 is flush with the top of the working platform 1. The lower section of the fixed frame 113 extends into the avoidance groove 8.

[0037] The specific implementation method is as follows: When in use, the thin film to be coated is placed on the working platform 1 and adsorbed and fixed through the vacuum adsorption holes 9.

[0038] Push the moving seat 5 to move on the sliding rod 4. When the moving seat 5 moves, the first gear 52 meshes with the first rack 55 to drive the rotation of the rotating shaft 51. The second gear 53 will rotate to drive the rotation of the third gear 57. The third gear 57 drives the rotation of the sleeve 56. During this period, the extrusion rod 512 extends out of the extrusion sleeve 56 by centrifugal force, and the sleeve 56 will displace outward, thereby moving the top contact rod 58 to the top contact groove 124 of the extrusion bearing platform 123, causing the bearing platform 123 to move upward, driving the movement of the second rack 127, and then driving the rotation of the discharge plate 7 through the fourth gear 126 to control the slurry to flow out from the discharge port 71, and at the same time, the moving seat 5 is flattened by the flattening piece 72 during the movement.

[0039] During the movement of the moving seat 5, both sides of the film are inserted between the lower support plate 118 and the support frame 114. The position between the support plate 118 and the support frame 114 can be adjusted through the cooperation of the moving table 1113 and the bolt 1114. When the third gear 57 rotates, it drives the bevel gear ring 111 to rotate, and then the first bevel gear 112, the transmission rod 115, and the second bevel gear 119 drive the third bevel gear 1110 to rotate, causing the transmission rod 1111 and the roller 116 to rotate, thereby driving the friction belt 117 to rotate clockwise to Figure 2 straighten the film on this basis. The excess slurry flows into the collection box 6 through the collection tank. And during the reset of the moving seat 5, the push-pull rod body is pulled to disengage the first gear 52 from the first rack 55. In this way, the first gear 52 does not rotate and does not generate centrifugal force during reset. Due to the reset spring two 122 and the extrusion spring one 510, the pressure-bearing table 123 and the discharge plate 7 are reset to block the discharge port 71 to prevent overflow and waste.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
