Description

Technical Field

[0001] The invention relates to the technical field of layered product processing, in particular to a polyimide material coating process and device. Background Art

[0002] The surface treatment of polyimide is difficult, and it is difficult to improve the surface properties and the bonding strength between it and the metal layer or other materials. The surface treatment requires degreasing, roughening, bridging, drying, plating and oxidation processes in sequence. When bridging, an adhesive needs to be applied to form a coating.

[0003] In the prior art, during the bridging process, the roller or scraper is adjusted to a suitable height from the primer, and then the adhesive material is applied to the primer using the roller or scraper to achieve the specified thickness. However, since the adhesive material will adhere to the outer surface of the roller or scraper during the coating process, if there is a lot of adhered material and it is not cleaned in time, the effective height of the roller or scraper that actually acts on the elastic layer during subsequent coating will be reduced, thereby making the coating thickness thinner. However, it is difficult for the staff to detect this subtle change during the coating process, and it is not convenient to quickly adjust the coating thickness according to this change, which is not conducive to precise control of the coating thickness of the polyimide adhesive material. Summary of the invention

[0004] The object of the present invention is to provide a polyimide material coating process and device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a polyimide material coating process and device, comprising a cart; a stirring tank is installed above the cart, the stirring tank is connected to a feeding pipe, a support plate is fixedly connected to one side of the cart, a first linear guide is fixedly installed to one side of the support plate, a first slide is slidably connected to the inside of the first linear guide, a measuring component is connected to one side of the first slide, the measuring component comprises a second linear guide, a second slide and a support seat, a roller is arranged on one side of the support seat, and the measuring component is used to measure the coating height of the roller; A load-bearing seat is fixedly connected to one side of the support seat, a motor is installed above the load-bearing seat, the motor is connected to a leveling component, and the leveling component is used to level the adhesive material.

[0006] Through the above technical solution, the adhesive can be stirred using a stirring tank, which can better ensure that the adhesive avoids block precipitation or uneven distribution problems caused by long-term storage, thereby making the entire coating surface consistent, and the coating thickness can be controlled through the measuring component to meet the coating requirements of the specified coating thickness.

[0007] Furthermore, the first slide is threadedly connected to a first screw rod, and the size of the first linear guide rail is larger than that of the second linear guide rail.

[0008] Through the above technical solution, rotating the first screw rod can enable the first slide to drive the second linear guide rail to perform linear motion in the vertical direction, thereby facilitating the position height adjustment of the structure connected to the second linear guide rail.

[0009] Furthermore, the second slide is threadedly connected to the second screw rod, and the second slide is connected to the support seat in a fixed manner.

[0010] Through the above technical solution, rotating the second screw can enable the second slide to drive the support seat to move linearly in the vertical direction, thereby facilitating the position height adjustment of the structure connected to the support seat.

[0011] Furthermore, a support shaft is fixedly connected to one side of the support seat, the roller is sleeved on the outer surface of the support shaft, the outer surface of the support shaft is fixedly connected to a support rod, the support rods are respectively located on both sides of the roller, the ends of the two support rods are fixedly connected to a material guide pipe, one end of the material guide pipe is interconnected with the material delivery pipe, and nozzles are arranged at equal distances on one side of the material guide pipe.

[0012] Through the above technical solution, the coating material inside the stirring tank is transported to the material guide pipe through the feed pipe, the coating material inside the material guide pipe can be sprayed out through the nozzle, and the coating material is rolled by the roller to make the coating material more evenly distributed.

[0013] Furthermore, an indicator rod is fixedly connected to the outer surface of the support shaft, a scale plate is fixedly connected to one side of the second linear guide rail, the indicator rod and the scale plate are connected by sliding connection, and the lower surface of the second linear guide rail is rotatably connected to a limit block.

[0014] Through the above technical solution, the limit block is used to fit with the ground, so as to indicate the position where the coating thickness is zero. When adjusting the height of the support seat, the support seat drives the indicator rod and the roller to adjust the height synchronously through the support shaft, and the lower ends of the indicator rod and the roller are located on the same horizontal line. When adjusting the height, the indicator rod will slide along the scale plate and indicate the scale on the scale plate. The indicated height value is the height difference between the lower end of the roller and the lower end of the limit block, that is, the thickness value that the roller can coat in this state.

[0015] Furthermore, the leveling assembly includes a fixed plate, a rotating shaft passes through the interior of the fixed plate, the rotating shaft and the fixed plate are connected in a rotational manner, one end of the rotating shaft is connected to the motor transmission, the other end of the rotating shaft is connected to the first gear, one side of the first gear is meshingly connected to the second gear, the second gear and the fixed plate are connected in a rotational manner, one side of the second gear is fixedly connected to a transmission shaft, one end of the transmission shaft is fixedly connected to a first connecting rod, the other end of the first connecting rod is rotationally connected to the second connecting rod, the upper surface of the load-bearing seat is fixedly connected to a guide seat, one side of the guide seat is slidably connected to a slider, and the slider and the second connecting rod are connected in a rotational manner.

[0016] Through the above technical solution, the first gear drives the second gear to rotate by rotating, and the second gear drives the slider to move through the first connecting rod and the second connecting rod, so that the slider is lifted and lowered on one side of the guide seat.

[0017] Furthermore, the diameter of the first gear is greater than the diameter of the second gear, and the first gear is an incomplete gear.

[0018] Through the above technical solution, since the first gear is an incomplete gear, the first gear will drive the second gear to rotate intermittently while rotating continuously, so that the slider can move intermittently, so as to achieve the purpose of stopping the lifting and lowering movement for a short time when the slider moves to the uppermost and lowermost ends.

[0019] Furthermore, a connecting plate is fixedly connected to one side of the sliding block, an indicating block is fixedly connected to the lower surface of the connecting plate, a flat knife is fixedly connected to the lower surface of the indicating block, and the thickness of the indicating block is greater than the thickness of the flat knife.

[0020] Through the above technical solution, the slider will drive the indicator block and the flat knife to move synchronously. When the slider drops to the lower end and remains in a state of stopping lifting for a short time, the flat knife will scrape and level the coating material after the roller is rolled while pushing the trolley, thereby ensuring the flatness of the coating material. The lower surface of the indicator block and the flat knife are on the same horizontal plane as the lowest point of the roller. When the actual thickness of the roller coating deviates from the set thickness, if the actual coating thickness is too thick, then when the coating material is scraped and leveled by the flat knife, the coating material will overflow to the side of the indicator block. If the actual coating thickness is too thin, then when the coating material is scraped and leveled by the flat knife, the coating material will not be able to adhere to the lower surface of the indicator block. Therefore, the indicator block can quickly determine whether there is an abnormality in the current coating thickness, which is convenient for the processing workers to quickly adjust the coating thickness.

[0021] Furthermore, an L-shaped rod is fixedly connected to one side of the load-bearing seat, a base is fixedly connected to the upper surface of the L-shaped rod, a cleaning assembly is connected to the base, the cleaning assembly includes a slide and a scraper, the slide is connected to the base in a sliding manner, the slide is connected to the scraper in a fixed manner, one side of the slide is rotatably connected to a driven rod, the other end of the driven rod is rotatably connected to a protrusion, the protrusion is fixedly connected to the first gear, and the thickness of the driven rod is less than the length of the rotating shaft.

[0022] Through the above technical solution, the coating material adhered to one side of the indicator block can be scraped off by using the cleaning component, thereby preventing the adhered coating material from affecting the subsequent indicating work of the indicator block.

[0023] A polyimide material coating process, using the above-mentioned device, comprises the following steps: S1. Degreasing the surface of the polyimide material plate and assisting the treatment by adding an additive to the surface; S2, roughening the surface; S3, the adhesive in the stirring tank is sent to the surface of the polyimide plate through the feeding pipe, and the leveling component leveling the adhesive material; S4, drying the polyimide plate with the coating; S5, sequentially performing chemical plating and magnetron sputtering plating on the polyimide plate; S6. Oxidizing the aluminum plating layer formed on the surface.

[0024] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the coating thickness of the coating material can be indicated by the indicator block. If the actual coating thickness is too thick, the coating material will overflow to the side of the indicator block when the coating material is scraped flat by the flat knife and the indicator block. If the actual coating thickness is too thin, the coating material will not be able to adhere to the lower surface of the indicator block when the coating material is scraped flat by the flat knife. Therefore, the indicator block can quickly determine whether there is an abnormality in the current coating thickness, thereby facilitating the processing workers to quickly adjust the coating thickness.

[0025] 2. In the present invention, when the cart is pushed to move and the coating material is coated by the roller, in the process of indicating the thickness of the coating material by the indicator block, the flat knife and the indicator block will move synchronously with the cart, and the flat knife will scrape and level the coating material after the roller is rolled during the movement, thereby ensuring the flatness of the coating material.

[0026] 3. In the present invention, by adjusting the position of the limit block to make it fit with the ground, the limit block can indicate the position where the coating thickness is zero, and the indicator rod and the lower end of the roller are located on the same horizontal line. When adjusting the height, the indicator rod will slide along the scale plate and indicate the scale on the scale plate. The indicated height value is the height difference between the lower end of the roller and the lower end of the limit block, that is, the thickness value that the roller can coat in this state. Therefore, when the position height of the support seat is adjusted by rotating the second screw, the coating thickness of the roller can be quickly adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present invention provides a technical solution: Figure 1 - Figure 8 A polyimide material coating process and device shown in the figure include a trolley 1; a stirring tank 2 is installed above the trolley 1, the stirring tank 2 is connected to a feed pipe 3, a support plate 4 is fixedly connected to one side of the trolley 1, a first linear guide 5 is fixedly installed on one side of the support plate 4, a first slide 6 is slidably connected inside the first linear guide 5, a measuring component is connected to one side of the first slide 6, the measuring component includes a second linear guide 8, a second slide 9 and a support seat 11, a roller 13 is arranged on one side of the support seat 11, and the measuring component is used to measure the coating height of the roller 13, a support shaft 12 is fixedly connected to one side of the support seat 11, the roller 13 is sleeved on the outer surface of the support shaft 12, a support rod 17 is fixedly connected to the outer surface of the support shaft 12, the support rod 17 is respectively located on both sides of the roller 13, and the ends of the two support rods 17 are fixedly connected to a guide pipe 18, one end of the guide pipe 18 is interconnected with the feed pipe 3, and a nozzle 19 is equidistantly arranged on one side of the guide pipe 18.

[0031] The method for coating the coating material is: first, place the adhesive into the stirring tank 2 for mixing, and then push the cart 1 to move along the area on the surface of the polyimide plate that needs to be coated. During this process, the coating material is continuously mixed inside the stirring tank 2. At the same time, the coating material inside the stirring tank 2 is transported to the guide pipe 18 through the feed pipe 3. The coating material inside the guide pipe 18 can be sprayed out through the nozzle 19. The roller 13 rolls the coating material during the movement to make the coating material more evenly distributed. The stirring tank 2 is a prior art with a stirring mechanism on the inside, which can avoid agglomeration or uneven distribution due to long-term storage, thereby making the thermal insulation performance of the entire coating surface more consistent.

[0032] See also Figure 1-Figure 4 The first slide 6 is threadedly connected to the first screw rod 7, the size of the first linear guide 5 is larger than the size of the second linear guide 8, the second slide 9 is threadedly connected to the second screw rod 10, the second slide 9 is connected to the support seat 11 in a fixed connection, the outer surface of the support shaft 12 is fixedly connected to the indicator rod 15, one side of the second linear guide 8 is fixedly connected to the scale plate 14, the indicator rod 15 and the scale plate 14 are connected in a sliding manner, and the lower surface of the second linear guide 8 is rotatably connected to the limit block 16.

[0033] The method for adjusting and controlling the coating thickness of the coating material is as follows: first, rotate the limit block 16 to make it parallel to the second linear guide 8, then rotate the first screw rod 7, the first screw rod 7 drives the first slide 6 to move downward along the first linear guide 5 by rotation, and the first slide 6 drives the second linear guide 8 to move synchronously, thereby driving the structure connected to the second linear guide 8 to move downward synchronously, when the limit block 16 at the lower end of the second linear guide 8 is tightly in contact with the ground, the rotation of the first screw rod 7 can be stopped at this time, when the limit block 16 is in contact with the ground, it indicates the position where the coating thickness is zero, and then rotate the second screw rod 10, the second screw rod 10 drives the second slide 9 to move upward along the second linear guide 8 by rotation, so that the second slide 9 drives its connection through the support seat 11 The connected structure moves upward synchronously. When the height of the support seat 11 is adjusted, the support seat 11 drives the indicator rod 15 and the roller 13 to adjust the height synchronously through the support shaft 12, and the lower ends of the indicator rod 15 and the roller 13 are located on the same horizontal line. The indicator rod 15 will slide along the scale plate 14 when adjusting the height, and indicate the scale on the scale plate 14. The indicated height value is the height difference between the lower end of the roller 13 and the lower end of the limit block 16, that is, the thickness value that the roller 13 can apply in this state. When the indicator rod 15 indicates the required coating thickness, the rotation of the second screw rod 10 can be stopped, and then the limit block 16 is rotated in the opposite direction to reset it, so that the limit block 16 remains perpendicular to the second linear guide rail 8, thereby avoiding affecting the movement of the cart 1.

[0034] See also Figure 1-Figure 7 A load-bearing seat 20 is fixedly connected to one side of the support seat 11, and a motor 21 is installed above the load-bearing seat 20. The motor 21 is connected to a leveling component, and the leveling component is used to level the adhesive material. The leveling component includes a fixed plate 22, and a rotating shaft 23 runs through the interior of the fixed plate 22. The connection between the rotating shaft 23 and the fixed plate 22 is a rotation connection. One end of the rotating shaft 23 is transmission-connected to the motor 21, and the other end of the rotating shaft 23 is connected to a first gear 24. One side of the first gear 24 is meshedly connected to a second gear 25. The second gear 25 is connected to the fixed plate 22 in a rotation connection. One side of the second gear 25 is fixedly connected to a transmission shaft 26. One end of the shaft 26 is fixedly connected to the first connecting rod 27, and the other end of the first connecting rod 27 is rotatably connected to the second connecting rod 28. The upper surface of the load-bearing seat 20 is fixedly connected to the guide seat 30, and one side of the guide seat 30 is slidably connected to the slider 29. The connection method between the slider 29 and the second connecting rod 28 is a rotational connection. The diameter of the first gear 24 is greater than the diameter of the second gear 25. The first gear 24 is an incomplete gear. One side of the slider 29 is fixedly connected to a connecting plate 31, and the lower surface of the connecting plate 31 is fixedly connected to an indicating block 32, and the lower surface of the indicating block 32 is fixedly connected to a flat knife 33, and the thickness of the indicating block 32 is greater than the thickness of the flat knife 33.

[0035] The principle of leveling the coating material is that when the trolley 1 is pushed to move and the coating material is coated by the roller 13, the flat knife 33 will move synchronously with the trolley 1. During the movement, the flat knife 33 will scrape and level the coating material after being rolled by the roller 13, thereby ensuring the flatness of the coating material.

[0036] The principle of indicating the coating thickness of the coating material is as follows: when the cart 1 is pushed to move and the coating material is coated by the roller 13, the motor 21 is first started, and the motor 21 drives the first gear 24 to rotate through the rotating shaft 23, and the first gear 24 drives the second gear 25 to rotate by rotating, and the second gear 25 drives the slider 29 to move through the first connecting rod 27 and the second connecting rod 28, and the guide seat 30 guides and limits the movement of the slider 29, so that the slider 29 is linearly lifted and lowered on one side of the guide seat 30, and the slider 29 drives the indicating block 32 and the flat knife 33 to move synchronously, and because the first gear 24 is an incomplete gear, the first gear 24 will drive the second gear 25 to rotate intermittently when it rotates continuously, so that the slider 29 moves intermittently, so that the slider 29 will move when it moves to the uppermost and lowermost ends. The purpose of keeping the lifting and lowering movement stopped for a short time is to make the indicator block 32 and the flat knife 33 stop lifting and lowering for a short time when they move to the uppermost and lowermost ends. When the indicator block 32 stops lifting and lowering at the lowermost end, the indicator block 32 and the flat knife 33 can move with the trolley 1 to scrape and level the coating material after rolling by the roller 13. When the indicator block 32 stops lifting and lowering at the uppermost end, the thickness of the coating material can be indicated. If the actual coating thickness is too thick, then when the coating material is scraped and leveled by the flat knife 33, the coating material will overflow to the side of the indicator block 32. If the actual coating thickness is too thin, then when the coating material is scraped and leveled by the flat knife 33, the coating material will not be able to adhere to the lower surface of the indicator block 32. Therefore, the indicator block 32 can quickly determine whether there is an abnormality in the current coating thickness, thereby facilitating the processing workers to quickly adjust the coating thickness.

[0037] See also Figure 1-Figure 8 An L-shaped rod 34 is fixedly connected to one side of the load-bearing seat 20, and a base 35 is fixedly connected to the upper surface of the L-shaped rod 34. The base 35 is connected to a cleaning assembly, and the cleaning assembly includes a slide 36 and a scraper 37. The connection between the slide 36 and the base 35 is a sliding connection, and the connection between the slide 36 and the scraper 37 is a fixed connection. A driven rod 38 is rotatably connected to one side of the slide 36, and a protrusion 39 is rotatably connected to the other end of the driven rod 38. The protrusion 39 is fixedly connected to the first gear 24. The thickness of the driven rod 38 is less than the length of the rotating shaft 23, and the height of the scraper 37 is greater than the height of the indicator block 32. The indicator block 32 has a conical structure when viewed from above.

[0038] The principle of cleaning the indicator block 32 is as follows: when the slider 29 drives the indicator block 32 to rise to the uppermost end and maintains a state of stopping lifting for a short time, since the first gear 24 is eccentrically connected to the protrusion 39, the first gear 24 will drive the driven rod 38 to move through the protrusion 39 during the rotation process, and the driven rod 38 will drive the slide 36 to move, and under the support and guiding action of the base 35, the driven rod 38 will drive the slide 36 to reciprocate left and right, and when the slide 36 drives the scraper 37 to reciprocate left and right, the coating material adhered to one side of the indicator block 32 will be scraped off, thereby preventing the adhered coating material from affecting the subsequent indication work of the indicator block 32.

[0039] A polyimide material coating process is also proposed, which is carried out using the above-mentioned device and includes the following steps: S1. Degreasing the surface of the polyimide material plate and assisting the treatment by adding an additive to the surface; S2, roughening the surface; S3, the adhesive in the stirring tank 2 is sent to the surface of the polyimide plate through the feeding pipe 3, and the leveling component leveling the adhesive material; S4, drying the polyimide plate with the coating; S5, sequentially performing chemical plating and magnetron sputtering plating on the polyimide plate; S6.
