Description

Technical Field

[0001] This utility model relates to the field of coating equipment, and in particular to a double-sided vertical coating mechanism. Background Technology

[0002] In the field of flexible materials processing, coating is one of the key processes, and its quality and efficiency directly affect product performance. The current mainstream method for coating flexible materials involves laying the material flat on a planar worktable, fixing it through vacuum adsorption, and then coating one side. This method has significant drawbacks: 1. Vacuum adsorption systems have complex structures and can only achieve single-sided coating. To complete double-sided coating, the material needs to be flipped and the operation repeated, resulting in low coating efficiency and difficulty in meeting the needs of mass production.

[0003] 2. When the slurry has not cured after coating, it is necessary to manually or mechanically remove the material from the workbench and transfer it to the curing area. During this process, the slurry is easily scratched and flowed by external forces, which will damage the integrity of the coating layer and greatly reduce the coating yield.

[0004] 3. Uneven stress on the material during planar coating can easily cause local wrinkles, especially for thin, flexible materials. Wrinkles can lead to inconsistent coating thickness and affect the stability of product quality.

[0005] To address the aforementioned issues, the industry urgently needs a coating mechanism that can achieve simultaneous coating on both sides and avoid transfer damage when the slurry is not fully cured, in order to improve coating efficiency and yield. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0007] A double-sided vertical coating mechanism includes a frame on which a worktable is fixedly mounted; A vertical support is fixedly installed in the middle of the workbench, and a tensioning frame is detachably installed inside the vertical support. A flexible material is installed inside the tensioning frame. An X-axis conveying mechanism is fixedly installed on both the left and right sides of the workbench. A Z-axis conveying mechanism is set on the X-axis conveying mechanism. The X-axis conveying mechanism drives the Z-axis conveying mechanism to move closer to or away from the tension frame. A coating unit is set on the Z-axis conveying mechanism. The Z-axis conveying mechanism drives the coating unit to move up and down. The two coating units coat the two sides of the flexible material respectively.

[0008] Furthermore, the two coating units are arranged symmetrically to each other.

[0009] Furthermore: the coating unit includes a coating slide, a hopper, and a slit opening. The Z-axis conveying mechanism drives the coating slide to move up and down. The hopper is fixedly installed on the coating slide. The slit opening is integrally formed and set on the bottom side edge of the hopper. The coating unit coats the flexible material from bottom to top within the tension frame through the slit opening.

[0010] Furthermore, the bottom side of the hopper is formed with an inclined coating head, and a slit opening is integrally formed in the inclined coating head. The inclined coating head coats the surface of the flexible material through the slit opening.

[0011] Furthermore: the side of the vertical support is formed with a square groove, the tensioning frame is installed in the square groove with clearance fit, and several horizontal quick clamps are fixedly installed on the side of the vertical support, and the tensioning frame is pressed into the square groove by the several horizontal quick clamps.

[0012] Furthermore: the tensioning frame includes a left frame, a middle frame, and a right cover. A positioning slot is formed on the inner edge of the right side of the left frame, and a frame-shaped protrusion is formed on the inner edge of the left side of the middle frame. The frame-shaped protrusion is fitted into the positioning slot with a gap fit. An insertion frame is formed on the inner edge of the left side of the right cover. The insertion frame is inserted into the middle frame and the left frame with a gap fit. The left edge of the insertion frame is flush with the left surface of the left frame. The middle frame is fixedly installed between the left frame and the right cover by screws.

[0013] Furthermore, both the X-axis conveying mechanism and the Z-axis conveying mechanism adopt linear modules.

[0014] Furthermore: at least two slotted photoelectric switches are fixedly installed on the side of the Z-axis conveying mechanism, and a right-angled side is fixedly installed on the coating unit. When the coating unit moves up and down, the outer end of the right-angled side is inserted into the slotted photoelectric switch with a gap fit.

[0015] Furthermore, a right-angle bracket is fixedly installed between the vertical support and the workbench.

[0016] Furthermore, anti-slip pads are fixedly installed at all four ends of the bottom side of the frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. Improved efficiency: The double-sided synchronous coating design eliminates the need to flip the material, increasing efficiency by more than 1 times compared to the traditional single-sided coating method. Furthermore, the tension frame can be quickly assembled and disassembled, and coating and curing can be carried out in parallel, further improving the efficiency of mass production.

[0018] 2. Improved yield: The vertically taut flexible material is evenly stressed during coating, without wrinkles; after coating, the material does not need to be transferred immediately and can enter the curing area together with the taut frame, avoiding damage when the slurry is not cured. The coating yield has been increased from more than 85% in the traditional method to more than 98%.

[0019] 3. Stable quality: The X-axis and Z-axis conveying mechanisms adopt linear modules with a positioning accuracy of up to ±0.01mm, ensuring uniform coating thickness; the design of the inclined coating head and slit opening makes the slurry coating smoother, without bubbles or sagging.

[0020] 4. Easy to operate: The tensioning frame can be disassembled and assembled in just 30 seconds without the need for professional tools; the slotted photoelectric switch realizes automatic anti-collision protection, reducing the difficulty of operation and safety risks.

[0030] like Figure 1-9As shown, a double-sided vertical coating mechanism of the present invention includes a frame 1, on which a worktable 2 is fixedly installed; A vertical support 3 is fixedly installed in the middle of the workbench 2. A tensioning frame 4 is detachably installed inside the vertical support 3. A flexible material 5 is installed inside the tensioning frame 4. X-axis conveying mechanisms 6 are fixedly installed on both the left and right sides of the workbench 2. Z-axis conveying mechanisms 7 are provided on the X-axis conveying mechanisms 6. The X-axis conveying mechanisms 6 drive the Z-axis conveying mechanisms 7 to move closer to or further away from the tension frame 4. Coating units 8 are provided on the Z-axis conveying mechanisms 7. The Z-axis conveying mechanisms 7 drive the coating units 8 to move up and down. The two coating units 8 coat the two sides of the flexible material 5 respectively.

[0031] The principle is as follows: the flexible material 5 is fixedly installed in the tension frame 4, and the coating units 8 on the left and right sides of the tension frame 4 are used to coat the slurry on both sides of the flexible material 5. The X-axis conveying mechanism 6 drives the coating units 8 to move closer to or away from the surface of the flexible material 5 to control the coating thickness of the slurry. The flexible material 5 can be vertically fixed by the tension frame 4, and then the coating units 8 on both sides are used to synchronously lift and coat the material, which avoids stress concentration that could cause the flexible material 5 to break. At the same time, it can also speed up the coating efficiency on both sides of the flexible material 5.

[0032] The flexible material 5 of this utility model can be a flexible film, flexible circuit board, flexible tape, flexible paper, etc., with a wide range of applications. It can achieve the technical effect of vertically stretching the flexible material 5 and simultaneously coating both sides.

[0033] Furthermore: the two coating units 8 are arranged symmetrically to each other; each coating unit 8 includes a coating slide 81, a hopper 82, and a slit opening 83. The Z-axis conveying mechanism 7 drives the coating slide 81 to move up and down. The hopper 82 is fixedly installed on the coating slide 81. The slit opening 83 is integrally formed on the bottom edge of the hopper 82. The coating unit 8 coats the flexible material 5 from bottom to top within the tension frame 4 through the slit opening 83. The slurry to be coated is placed into the hopper 82. The slurry will flow to the slit opening 83 for uniform output due to its own weight. With the upward movement of the coating unit 8, the slurry can be uniformly coated on the surface of the flexible material 5. By vertically tensioning and coating both sides, the coating efficiency and coating quality are accelerated.

[0034] Furthermore, the bottom side of the hopper 82 is formed with an inclined coating head 9, and the slit opening 83 is integrally formed in the inclined coating head 9. The inclined coating head 9 coats the surface of the flexible material 5 through the slit opening 83. The coating head can be inserted obliquely into the tension frame, so that the slit opening 83 abuts against the surface of the flexible material 5 to perform mechanical coating action, ensuring the uniformity of coating, thereby improving the coating quality of the slurry on the surface of the flexible material 5.

[0035] Furthermore: the vertical support 3 has a square groove 10 formed on its side, and the tensioning frame 4 is fitted into the square groove 10 with a clearance fit. Several horizontal quick clamps 11 are fixedly installed on the side of the vertical support 3, and the tensioning frame 4 is pressed into the square groove 10 by the several horizontal quick clamps 11. This allows for quick installation and removal of the tensioning frame 4 in the square groove 10. After the flexible material 5 is coated, the corresponding tensioning frame 4 can be removed and placed aside for the surface slurry to dry. At this time, another tensioning frame 4 can be used to install the flexible material 5 to be coated and reinstalled into the square groove 10 for vertical double-sided coating operation, which is beneficial for batch coating testing and production.

[0036] Furthermore: the tensioning frame 4 includes a left frame 41, a middle frame 42, and a right cover 43. A positioning slot 12 is formed on the inner edge of the right side of the left frame 41. A frame-shaped protrusion 13 is formed on the inner edge of the left side of the middle frame 42. The frame-shaped protrusion 13 is fitted into the positioning slot 12 with a clearance fit. An insertion frame 14 is formed on the inner edge of the left side of the right cover 43. The insertion frame 14 is inserted into the middle frame 42 and the left frame 41 with a clearance fit. The left edge of the insertion frame 14 is flush with the left surface of the left frame 41. The middle frame 42 is fixedly installed on the left frame 41 and the right cover 43 by screws. Between the right cover 43; when installing the flexible material 5, first disassemble the tensioning frame 4, put the flexible material 5 into the positioning slot 12, and then install the middle frame 42. The frame-shaped protrusion 13 of the middle frame 42 will press into the positioning slot 12, thereby achieving the initial positioning of the flexible material 5. Then, install the right cover 43. The insertion frame 14 on the left side of the right cover 43 will abut against the flexible material 5 and insert into the middle frame 42 and the left frame 41, achieving the technical effect of tensioning the flexible material 5, satisfying the tensioning effect during vertical double-sided coating, and ensuring the stability of double-sided coating.

[0037] Furthermore: both the X-axis conveying mechanism 6 and the Z-axis conveying mechanism 7 adopt linear modules; the X-axis direction can enable the coating unit 8 to approach or move away from the two sides of the flexible material 5, and the Z-axis direction can enable the coating unit 8 to lift and coat on the flexible material 5.

[0038] Furthermore: At least two slotted photoelectric switches 15 are fixedly installed on the side of the Z-axis conveying mechanism 7, and a right-angled side 16 is fixedly installed on the coating unit 8. When the coating unit 8 moves up and down, the outer end of the right-angled side 16 is inserted into the slotted photoelectric switch 15 with a gap fit. During the up and down movement, the real-time height detection of the coating unit 8 can be achieved by inserting the right-angled side 16 into the slotted photoelectric switch 15, so as to avoid the coating unit 8 from contacting the tensioning frame 4 and achieve a stable coating effect.

[0039] Furthermore, a right-angle frame 17 is fixedly installed between the vertical support 3 and the workbench 2; the right-angle frame 17 ensures that the vertical support 3 remains in a vertical state, thereby ensuring the vertical assembly of the tension frame 4 and facilitating the coating operation on both sides of the flexible material 5.

[0040] Furthermore, anti-slip pads 18 are fixedly installed at all four ends of the bottom side of the frame 1; it can be placed on a table or the ground for use, and can effectively prevent slipping.

[0041] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
