Description

Technical Field

[0001] The invention belongs to the technical field of production of multilayer polyimide reinforcing sheets, in particular to a coating device for a laminated polyimide reinforcing sheet. Background Art

[0002] Laminated polyimide reinforcing sheet is a high-performance composite material, mainly composed of multiple layers of polyimide film or other reinforcing materials. The production of laminated polyimide reinforcing sheet is mainly through coating polyimide liquid or polyimide film on the specified substrate, and then drying and amination. The film formed is generally distributed in the form of a whole piece (PI) film and multiple small pieces of film. Among them, the production of small pieces of film is commonly produced by anilox roller coating. The holes on the anilox roller carry the coating liquid to rotate, so that the anilox roller contacts the substrate and starts to rotate. The coating liquid is evenly transferred to the substrate under the action of the anilox roller to form regular pieces of liquid film. After subsequent steps, the coating is completed.

[0003] In this method, during the coating process, even if a scraper is used to tidy up the coating liquid, a layer of film will still remain on the surface of the roller. If these films are stacked layer by layer, it will affect the quality of coating and may also cause blockage and jamming.

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figures 1 to 8 As shown, the present invention provides a laminated polyimide reinforcing sheet coating device, comprising a base 1, a textured coating component 3 and a cleaning roller 7 are rotatably connected inside the base 1, and a liquid replenishing component 5 and a coating mechanism 6 are fixedly connected in the middle of the base 1;

[0032] The liquid replenishing assembly 5 includes a liquid replenishing tank 51 fixedly connected to the base 1, a liquid replenishing tube 52 fixedly connected to the top of the liquid replenishing tank 51, a guide baffle 53 fixedly connected inside the liquid replenishing tube 52, and a resisting scraper 54 fixedly connected to the bottom of the liquid replenishing tank 51;

[0033] The smearing mechanism 6 includes a smearing component 61 fixedly connected to the base 1, an adjustment component 62 is slidably connected to one side of the smearing component 61, a support rod 63 is arranged between the smearing component 61 and the adjustment component 62, a limiting slide groove 64 is opened in the middle of the adjustment component 62, and the support rod 63 is slidably connected inside the limiting slide groove 64.

[0034] The above scheme is adopted: by setting a liquid replenishing groove 51, the textured coating component 3 can pass through the liquid replenishing groove 51 to replenish the coating liquid, and then the resisting scraper 54 removes the excess coating liquid. After the textured coating component 3 contacts the glass substrate 4 and completes the coating, the textured coating component 3 will rotate toward the coating component 61, so that the movable resisting block 627 is squeezed by the positioning protrusion 33, and the fork-shaped squeezing block 622 is driven to move by pushing the sliding bracket 621, and the second spring 623 is squeezed to move downward, so that the auxiliary coating gasket 619 is coated with cleaning liquid on the horizontal spacing between the recessed eyes 32, and the main coating gasket 615 is coated with cleaning liquid on the longitudinal spacing between the recessed eyes 32, so as to complete the coating of the cleaning liquid around the recessed eyes 32; finally, it rotates to the cleaning roller 7, and the cleaning roller 7 absorbs the cleaning liquid and the polyimide film between the recessed eyes 32 to achieve the cleaning effect, so that the appearance of the coating roller body 31 remains clean.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the lower end of the base 1 is fixedly connected to the conveyor belt 2, the top of the conveyor belt 2 conveys a glass substrate 4, the upper end of the base 1 is rotatably connected to the cleaning roller 7, the anilox coating assembly 3 includes a coating roller body 31, the middle part of the coating roller body 31 is provided with a ring-shaped recessed eye 32, both ends of the coating roller body 31 are fixedly connected with a positioning protrusion 33, the recessed eye 32 corresponds to the position of the positioning protrusion 33, the bottom of the coating roller body 31 is in conflict with the glass substrate 4, the coating roller body 31 is vertically distributed with the cleaning roller 7, and is in conflict with the cleaning roller 7.

[0036] The above scheme is adopted: by setting the textured coating component 3, when the recessed eye 32 passes through the liquid replenishing component 5, the recessed eye 32 will be immersed in the coating liquid, so that the coating liquid fills the interior of the recessed eye 32 to carry the coating liquid, and then the coating roller body 31 rotates to make the recessed eye 32 carrying the coating liquid contact with the glass substrate 4. When the coating liquid contacts the glass substrate 4, the coating liquid will adhere to the glass substrate 4, and the coating liquid forms a neat and separate sheet of polyimide film on the top of the glass substrate 4, thereby completing the coating. By setting the positioning protrusion 33, the coating roller body 31 can synchronously drive the coating mechanism 6 and the cleaning roller 7 to operate to clean the surface of the coating roller body 31, so as to avoid the accumulation of polyimide film on the coating roller body 31, which affects the coating.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, the liquid replenishing groove 51 is in contact with the coating roller body 31 and its specifications match those of the coating roller body 31, the liquid replenishing tube 52 is externally connected to an infusion pump, the side of the guide baffle 53 away from the coating roller body 31 is set to face obliquely downward, the contact scraper 54 matches the specifications of the coating roller body 31, and the contact scraper 54 is in close contact with the coating roller body 31.

[0038] The above scheme is adopted: by setting up a liquid replenishing component 5, the liquid replenishing groove 51 is in contact with the coating roller body 31, so that the coating liquid inside the recessed eye 32 can be replenished in time, and at the same time, the rotation direction of the recessed eye 32 is downward toward the liquid replenishing groove 51, so that the recessed eye 32 passes from the liquid replenishing groove 51 to the contact scraper 54, and the contact scraper 54 is used to scrape the coating liquid at the recessed eye 32 flat, so as to control the amount of coating liquid inside the recessed eye 32 and avoid a large amount of coating liquid remaining on the outer surface of the coating roller body 31. The setting of the guide baffle 53 prevents the coating liquid replenished by the liquid replenishing pipe 52 to the liquid replenishing groove 51 from falling directly, and can be blocked by the guide baffle 53 to slow down the falling speed, so as to avoid splashing of the coating liquid due to falling.

[0039] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the smearing component 61 includes a main support 611 fixedly connected to the base 1, a cleaning liquid storage tube 612 is fixedly connected to the middle of the main support 611, and a liquid infusion tube 613 is fixedly connected to the cleaning liquid storage tube 612 on a side close to the coating roller body 31 in a linear manner, first liquid separation cavities 614 are evenly spaced inside the main support 611, a main smearing gasket 615 is fixedly connected inside the first liquid separation cavity 614, a movable smearing block 616 is linearly distributed and slidably connected inside the main support 611, first springs 617 are fixedly connected on both sides of the movable smearing block 616, a second liquid separation cavity 618 is opened inside the movable smearing block 616, and a side of the movable smearing block 616 close to the coating roller body 31 is fixedly connected to an auxiliary smearing gasket 619.

[0040] The above scheme is adopted: by setting up a coating component 61, the main coating gasket 615 and the auxiliary coating gasket 619 are used to coat the vertical gap and the horizontal gap between the recessed eyes 32 with cleaning liquid, so that the cleaning roller 7 can clean the residual polyimide film. The movable coating block 616 arranged inside the main support 611 can drive the auxiliary coating gasket 619 to move up and down reciprocatingly to prevent the cleaning liquid from being smeared into the recessed eyes 32. Through the first liquid separation cavity 614 and the second liquid separation cavity 618, the cleaning liquid can evenly penetrate the main coating gasket 615 and the auxiliary coating gasket 619 to coat the gap between the recessed eyes 32 to the right area, thereby ensuring the cleaning effect of the cleaning roller 7. The cleaning liquid storage tube 612 and the infusion tube 613 are arranged so that when the coating roller body 31 is in operation, the main coating gasket 615 and the auxiliary coating gasket 619 can always keep being soaked in the cleaning liquid.

[0041] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the main support 611 is located on the side of the coating roller body 31 away from the liquid replenishing tank 51, and is in conflict with the coating roller body 31. The infusion tube 613 is spaced apart with straight tubes and bellows, wherein the straight tube connects the cleaning liquid storage tube 612 with the first liquid separation chamber 614, wherein the bellows is fixedly connected to the movable smear block 616, and connects the cleaning liquid storage tube 612 with the second liquid separation chamber 618, the main smear gasket 615 and the auxiliary smear gasket 619 are both in conflict with the coating roller body 31, and are distributed in the middle of the recessed eye 32, the movable smear block 616 corresponds to the vertical position of the recessed eye 32, and one end of the first spring 617 is fixedly connected to the main support 611.

[0042] The above scheme is adopted: by setting the infusion tube 613 into two types, a straight tube and a corrugated tube, and distributing them at intervals, so that the straight tube is connected to the first liquid separation chamber 614, and the corrugated tube is fixedly connected to the movable smear block 616, so that the movable smear block 616 can still maintain the transportation of cleaning liquid when moving up and down, so that the main smear gasket 615 and the auxiliary smear gasket 619 are always kept in an infiltrated state, and at the same time, the movable smear block 616 is set to correspond to the vertical position of the recessed eye 32, so that the movable smear block 616 can smear the lateral interval of the recessed eye 32, and at the same time can cross the recessed eye 32 to prevent the cleaning liquid from entering the interior of the recessed eye 32.

[0043] like Figure 5 , Figure 6 and Figure 7As shown, the adjustment assembly 62 includes a sliding bracket 621 slidably connected to the support rod 63, a fork-shaped extrusion block 622 is linearly fixedly connected to one side of the sliding bracket 621 close to the main bracket 611, a second spring 623 and a third spring 626 are fixedly connected to both ends of the sliding bracket 621, a sliding support block 624 is slidably connected to both ends of the sliding bracket 621, a spring piece 625 is fixedly connected to the top of the sliding support block 624, and one end of the sliding support block 624 located on the outer side of the sliding bracket 621 is rotatably connected to a movable stop block 627. 621 is located on the side of the main bracket 611 away from the cleaning roller 7, the fork-shaped extrusion block 622 corresponds to the position of the movable smear block 616, the fork-shaped extrusion block 622 conflicts with the top of the movable smear block 616, one end of the second spring 623 is fixedly connected to the main bracket 611, the top of the spring piece 625 is fixedly connected to the sliding bracket 621, one end of the third spring 626 is fixedly connected to one end of the movable stop block 627 close to the main bracket 611, the movable stop block 627 corresponds to the position of the positioning protrusion 33, and the movable stop block 627 conflicts with the positioning protrusion 33.

[0044] The above scheme is adopted: the setting of the adjustment component 62 can push the adjustment component 62 to move through the rotation of the coating roller body 31, and the positioning protrusion 33 can control the rise and fall of the movable smear block 616. The fork-shaped squeezing block 622 set on the side of the sliding bracket 621 can squeeze the movable smear block 616 to move downward, so that the movable smear block 616 pushes the auxiliary smear gasket 619 to conflict with the coating roller body 31. An inclined surface is set at one corner of the fork-shaped squeezing block 622, and a slope corresponding to the fork-shaped squeezing block 622 is set on the top of the movable smear block 616 to facilitate the fork-shaped squeezing block 622 to push the movable smear block 616. The second spring 623 set between the sliding bracket 621 and the main bracket 611 can push the sliding bracket 621 to drive the fork-shaped squeezing block 622 to move, so that the movable smear block 616 can be pushed up by the first spring 617 to release the conflict with the coating roller body 31 to cross the recessed eye 32. The arrangement of the sliding support block 624, the spring piece 625, the third spring 626 and the movable stop block 627 can facilitate the movement of the sliding bracket 621 by pushing the positioning protrusion 33. The movable stop block 627 contacts the positioning protrusion 33 and is pushed by the positioning protrusion 33, so that the movable stop block 627 drives the sliding bracket 621 to move through the sliding support block 624, so that the fork-shaped squeezing block 622 squeezes the movable smear block 616. Then, the positioning protrusion 33 continues to move and pushes the sliding bracket 621 until it contacts the main bracket 611, so that the movable stop block 627 cannot move. Then, the positioning protrusion 33 will push the movable stop block 627 to flip over, and then pass over the movable stop block 627 to release it from the squeezed state, so that the second spring 623 can push the sliding bracket 621 to reset, thereby releasing the squeezing of the fork-shaped squeezing block 622 on the movable smear block 616, and causing the movable smear block 616 to rise to pass over the recessed eye 32.

[0045] like Figure 1 Figure 2 and Figure 4 As shown, a reserved hole matching the concave eye 32 is provided on the outside of the cleaning roller 7 , and tooth grooves matching the positioning protrusion 33 are provided at both ends of the cleaning roller 7 and meshedly connected with the positioning protrusion 33 .

[0046] The above solution is adopted: by opening reserved holes and tooth grooves on the cleaning roller 7, the cleaning roller 7 can rotate with the coating roller body 31 and perform targeted cleaning and absorption treatment on the gaps between the recessed eyes 32 to clean the polyimide film mixed with the cleaning liquid.

[0047] The working principle and use process of the present invention are as follows: during operation, the coating roller body 31 rotates, so that the recessed eye 32 passes through the replenishing groove 51 to replenish the coating liquid, and the excess coating liquid is scraped off by the resisting scraper 54, and then the recessed eye 32 rotates to the bottom of the recessed eye 32 to contact the glass substrate 4, so that the coating liquid inside the recessed eye 32 is retained on the glass substrate 4 to form a film with uniform specifications, and then the recessed eye 32 rotates toward the main support 611, at which time the movable resisting block 627 is squeezed by the positioning protrusion 33, so that the sliding support 621 pushes the fork-shaped squeezing block 622 to squeeze the second spring 623 to move downward, so that the auxiliary coating gasket 619 applies the cleaning liquid to the horizontal spacing between the recessed eyes 32, and at the same time, the main coating gasket 615 applies the cleaning liquid to the longitudinal spacing between the recessed eyes 32, so as to complete the cleaning of the gaps around the recessed eye 32;

[0048] Then the positioning protrusion 33 squeezes the movable stop block 627 to flip, so that the movable stop block 627 is released from the pushed state, and the sliding bracket 621 is unlocked, so that it is pushed to reset by the second spring 623, so that the fork-shaped squeezing block 622 releases the squeezing of the movable smear block 616, and the movable smear block 616 is pushed upward by the first spring 617, just passing over the recessed eye 32, and then rotates to the cleaning roller 7, and the cleaning roller 7 absorbs the cleaning liquid and the polyimide film between the recessed eye 32 to achieve the cleaning effect, so that the appearance of the coating roller body 31 remains clean and tidy, and the accumulation of polyimide film is avoided.
