Description

Technical Field

[0001] The present invention relates to the technical field of coating, and particularly to a PI film coating device for manufacturing a non-polarizer display panel. Background Art

[0002] The PI (polyimide) film coating device is a key device in the process of manufacturing a non-polarizer display panel, mainly used for precisely coating a layer of PI film on a specific substrate. This device usually consists of a liquid supply system, a coating head, a substrate transfer system, a drying system, a control system, etc., and can achieve uniform and stable coating of the PI film to meet the high-performance requirements of the display panel. The PI composite film is the polyimide film. The polyimide film is one of the better-performing film-like insulating materials in the world. It is formed by polycondensation of pyromellitic dianhydride and diaminodiphenyl ether in a strongly polar solvent, followed by casting into a film and then imidization. It is one of the varieties with the highest thermal stability among known organic polymers, mainly because the molecular chain contains a large number of aromatic rings.

[0003] When the existing PI film coating device coats the panel, there are problems such as the shaking of the panel affecting the coating effect, and excessive coating resulting in too thick a coating, which affects the use of the panel. Therefore, a new design has been carried out for this situation. Summary of the Invention

A slide rail frame is fixedly connected to the top of the composite base. The outside of the slide rail frame is slidably connected to the bottom of the processing mechanism. One side of the top of the composite base near the middle of the slide rail frame is fixedly connected with a fixing component. By placing the display panel inside the fixing component, the fixing component plays a role in fixing the panel, avoiding shaking during operation and preventing the coating effect from being affected. A moving frame body is slidably connected to the outside of the slide rail frame. A liquid storage tank is fixedly connected to the top of the moving frame body.

A heater is fixedly connected to the top of the outside of the liquid storage tank. A heater is arranged outside the liquid storage tank. The material is heated by the heater to avoid the material cooling during operation, affecting the coating effect, and avoiding uneven coverage during the coating process, affecting the product quality and reducing the operation efficiency. A coating mechanism is fixedly connected to one side of the outside of the liquid storage tank near the composite base. By sliding the moving frame body on the outside of the slide rail frame, the coating mechanism is driven to slide on the surface of the panel, thereby achieving the coating effect on the panel. The coating mechanism controls the flow rate of the raw material to avoid excessive flow of the material, resulting in too thick coating and affecting the subsequent use effect.

[0005] Preferably, the fixing component includes a fixing base. The bottom of the fixing base is fixedly connected to the top of the composite base. A receiving block is fixedly connected to the outside of the fixing base away from the composite base. When the panel is placed inside the fixing base, the protection mechanism is controlled by the first electric push rod to squeeze the panel, thereby achieving the effect of fixing the object, facilitating subsequent coating, avoiding shaking during the coating process, and preventing deviation during coating, affecting the coating quality.

[0006] Preferably, the protection mechanism includes a square frame. A connecting rod is fixedly connected to one side of the outside of the square frame near the square plate. When the square frame contacts the panel, the connecting rod slides towards the square plate side, causing the spring strip to be squeezed, thereby achieving a shock absorption and buffering effect through the spring structure, avoiding excessive extrusion and damaging the panel. The outside of the connecting rod is slidably connected to the outside of the square plate. A spring strip is sleeved on the outside of the connecting rod near the square frame.

On the outer side of the circular frame away from the moving frame body, a coating outer shell is fixedly connected. A roller shaft is rotatably connected to the inner side of the coating outer shell. The PI film liquid enters the interior of the coating outer shell from the plastic pipe and then rotates on the surface of the panel through the roller shaft, thereby achieving the coating effect on the panel. By rotating the roller shaft inside the coating outer shell, the coating flow rate can be controlled to avoid excessive coating flow rate resulting in too thick a coating layer, which affects the product quality. On the outer side of the coating outer shell close to the circular frame, a second electric push rod is fixedly connected. The second electric push rod controls the lifting of the coating outer shell to facilitate fitting the surface of the panel and improve the coating effect. The outer side of the second electric push rod away from the coating outer shell is fixedly connected to the outer side of the moving frame body.

[0008] Preferably, the processing mechanism includes a processing frame body. The bottom of the processing frame body is slidably connected to the outer side of the slide rail frame. On the outer side of the processing frame body away from the composite base, a box body is fixedly connected. By increasing the travel of the air flow through the box body, the effect of uniformly conveying the air flow can be achieved, thereby achieving the effect of maintaining uniform drying and curing and avoiding uneven drying, which affects the operation efficiency. A dryer is fixedly connected to the outer side of the box body. The dryer generates hot air flow into the interior of the box body and then flows out from the air outlet housing, thereby achieving the drying effect on the coating layer and achieving the effect of drying and curing. On the outer side of the box body close to the processing frame body, a connecting pipe is fixedly connected. On the outer side of the connecting pipe away from the box body, an air outlet housing is fixedly connected.

By the rotating mechanism rubbing against the inner wall of the air outlet housing, the effect of cleaning dust can be achieved, avoiding dust accumulation after long-term operation, which affects the subsequent gas flow effect. A spring rod is fixedly connected to the outer side of the air outlet housing. The air outlet housing is connected through the spring rod. The spring material plays a role in shock absorption and buffering, reducing the amplitude generated by the gas flow and improving the stability of the components. The outer side of the spring rod away from the air outlet housing is fixedly connected to the outer side of the processing frame body.

By forming the block surface grooves, the contact area is increased by grooving, the friction performance is improved, and at the same time, the chip removal effect is improved, dust adsorption is reduced, and the subsequent friction effect is prevented from being affected.

[0012] Preferably, the cutting mechanism includes a third electric push rod. After the coating layer is dried and cured, the third electric push rod controls the first frame to extrude towards the panel inside the fixing component. When the pressing plate contacts the panel, the elastic rod contracts for buffering to avoid damaging the panel. One side of the outside of the third electric push rod is fixedly connected to the outside of the processing frame body, and the side of the outside of the third electric push rod away from the processing frame body is fixedly connected to a first frame. When the third electric push rod controls the first frame to lift, the elastic rod restores its elasticity, increasing the shaking effect of the component on the coating layer and reducing the adhesion effect with the panel. An elastic rod is slidably connected to the outside of the first frame away from the third electric push rod, and a pressing plate is fixedly connected to one side of the outside of the elastic rod.

[0014] The present invention provides a PI film coating device for manufacturing a non-polarizer display panel, having the following beneficial effects: 1. The PI film coating equipment for manufacturing the polarizer-free display panel, through the design of the composite mechanism, places the display panel inside the fixing component, and the fixing component plays a role in fixing the panel to avoid shaking during operation and prevent affecting the coating effect. The PI film solution enters the inside of the liquid storage tank, which facilitates subsequent use and plays a role in uniform feeding to a certain extent, avoiding uneven coating. A heater is provided outside the liquid storage tank to heat the material and prevent the material from cooling during operation, which may affect the coating effect, and to avoid uneven coverage during coating, which may affect the product quality and reduce the operation efficiency. After fixing the panel, the moving frame slides outside the slide rail frame, driving the coating mechanism to slide on the surface of the panel, thereby achieving the coating effect on the panel. Secondly, the coating mechanism controls the flow rate of the raw material to avoid excessive flow of the material, resulting in too thick coating and affecting the subsequent use effect.

[0015] 2. The PI film coating equipment for manufacturing the polarizer-free display panel, through the design of the processing mechanism, generates hot air flow by the dryer and enters the inside of the box body, and then flows out from the air outlet housing, thereby achieving the drying effect on the coating layer and the effect of drying and curing.

Secondly, the coating mechanism 17 controls the flow rate of the raw material to avoid excessive flow of the material, resulting in too thick coating and affecting the subsequent use effect.

[0023] Second Embodiment. On the basis of the first embodiment, please refer to Figures 4 to 6 As shown, the fixing component 13 includes a fixing base 131. The bottom of the fixing base 131 is fixedly connected to the top of the composite base 11. A receiving block 132 is fixedly connected to one side of the outside of the fixing base 131 away from the composite base 11. A first electric push rod 133 is fixedly connected to one side of the outside of the receiving block 132. A square plate 134 is fixedly connected to the side of the first electric push rod 133 away from the receiving block 132. A protective mechanism 135 is slidably connected to one side of the outside of the square plate 134. When the panel is placed inside the fixing base 131, the first electric push rod 133 controls the protective mechanism 135 to squeeze the panel, thereby achieving the effect of fixing the object, facilitating subsequent coating, avoiding shaking during the coating process, preventing deviation during coating and affecting the coating quality. At the same time, the protective mechanism 135 plays a certain buffering effect, avoiding damage to the panel caused by excessive extrusion and increasing the use cost.

[0024] The protection mechanism 135 includes a square frame 1351. On one side of the square frame 1351 close to the square plate 134, a connecting rod 1354 is fixedly connected. The outer side of the connecting rod 1354 is slidably connected to the outer side of the square plate 134. A spring strip 1355 is sleeved on the outer side of the connecting rod 1354 close to the square frame 1351. On the side of the square frame 1351 far from the connecting rod 1354, a silica gel block 1352 is fixedly connected. When the square frame 1351 contacts the panel, the connecting rod 1354 slides towards the square plate 134, causing the spring strip 1355 to be squeezed, thereby achieving a shock-absorbing and buffering effect through the spring structure, avoiding excessive extrusion and damaging the panel. Secondly, the silica gel block 1352 is made of silica gel material, so as to increase the protection effect on the panel, reduce the amplitude of extrusion, and reduce the wear of the panel.

[0025] The coating mechanism 17 includes a circular frame 171. Between the opposite surfaces of the circular frame 171, a plastic pipe 172 is fixedly connected. On the side of the circular frame 171 far from the moving frame body 14, a coating outer shell 173 is fixedly connected. Inside the coating outer shell 173, a roller 174 is rotatably connected. On the side of the coating outer shell 173 close to the circular frame 171, a second electric push rod 175 is fixedly connected. On the side of the second electric push rod 175 far from the coating outer shell 173, it is fixedly connected to the outer side of the moving frame body 14. The PI film liquid enters the inside of the coating outer shell 173 from the plastic pipe 172, and then rotates on the surface of the panel through the roller 174, so as to achieve the coating effect on the panel. The second electric push rod 175 is used to control the lifting of the coating outer shell 173, so as to facilitate fitting the surface of the panel and improve the coating effect. The roller 174 rotates inside the coating outer shell 173, thereby controlling the coating flow rate and avoiding the coating layer being too thick due to excessive coating flow rate, which affects the product quality.

[0026] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 7 to 10 As shown, the processing mechanism 2 includes a processing frame body 21. The bottom of the processing frame body 21 is slidably connected to the outer side of the slide rail frame 12. On the side of the processing frame body 21 far from the composite base 11, a box body 22 is fixedly connected. On the outer side of the box body 22, a dryer 23 is fixedly connected. On the side of the box body 22 close to the processing frame body 21, a connecting pipe 24 is fixedly connected. On the side of the connecting pipe 24 far from the box body 22, an air outlet housing 25 is fixedly connected. The hot air flow generated by the dryer 23 enters the inside of the box body 22 and then flows out from the air outlet housing 25, so as to achieve the drying effect on the coating layer, so as to achieve the drying and curing effect. By increasing the air flow travel through the box body 22, the effect of uniformly conveying the air flow is achieved, so as to achieve the effect of maintaining uniform drying and curing and avoid uneven drying, which affects the operation efficiency.

[0027] On one side of the processing frame body 21 away from the box body 22, a cutting mechanism 28 is fixedly connected. At the bottom inside the air outlet housing 25, a rotating mechanism 27 is fixedly connected. On the outside of the air outlet housing 25, a spring rod 26 is fixedly connected. On the side of the spring rod 26 away from the air outlet housing 25, it is fixedly connected to the outside of the processing frame body 21. The hot air flow impacts the rotating mechanism 27 to drive the rotation of the rotating mechanism 27. The rotating mechanism 27 rubs against the inner wall of the air outlet housing 25 to clean the dust, so as to avoid dust accumulation after long-term operation and affect the subsequent gas flow effect. The air outlet housing 25 is connected by the spring rod 26, and the spring material plays a role of shock absorption and buffering, reducing the amplitude generated by the gas flow and improving the stability of the components.

[0028] The rotating mechanism 27 includes a rotating base 271. The bottom of the rotating base 271 is fixedly connected to the inside of the air outlet housing 25. The outside of the rotating base 271 is rotatably connected to a rotating bracket 272. Between the opposite surfaces of the rotating bracket 272, a paddle 273 is fixedly connected. On the side of the rotating bracket 272 away from the paddle 273, an adapter plate 274 is fixedly connected. The hot air flow impacts the paddle 273, and the impact drives the rotation of the rotating bracket 272, so that the adapter plate 274 rubs against the inner wall of the component to clean the dust particles. By rubbing, the internal dust particles are reduced to keep the component clean. At the same time, the contact area with the air flow is increased through the paddle 273, improving the rotation efficiency of the component.

[0029] Inside the adapter plate 274, a friction block 275 is rotatably connected. On the outside of the friction block 275, a block surface groove 276 is provided. The friction block 275 is arranged inside the adapter plate 274. When the adapter plate 274 rotates, it drives the rotation of the friction block 275. The friction block 275 wipes and cleans the dust on the inner wall of the equipment to reduce the dust residue. By providing the block surface groove 276, the contact area is increased through the grooving, improving the friction performance, and at the same time improving the chip removal effect, reducing the dust adsorption and avoiding affecting the subsequent friction effect.

[0030] The cutting mechanism 28 includes a third electric push rod 281. One side outside the third electric push rod 281 is fixedly connected to the outer side of the processing frame 21. The side of the third electric push rod 281 far from the processing frame 21 is fixedly connected to a first frame 282. A resilient rod 283 is slidably connected to the side of the first frame 282 far from the third electric push rod 281. One side of the resilient rod 283 is fixedly connected to a pressing plate 284. A plate surface groove 285 is formed on the side of the pressing plate 284 far from the resilient rod 283. After the coating layer is dried and cured, the first frame 282 is controlled by the third electric push rod 281 to extrude the panel inside the fixing assembly 13. When the pressing plate 284 contacts the panel, it is buffered by the contraction of the resilient rod 283 to avoid damaging the panel. When the pressing plate 284 moves towards the inside of the first frame 282, the two sides of the panel are cut by the cutting block 287 to prevent the coating layer from overflowing, so as to achieve the effect of cleaning the excess coating layer.

[0031] A spring frame 286 is fixedly connected to the edge of the first frame 282 on the side close to the third electric push rod 281. A cutting block 287 is fixedly connected to one side of the spring frame 286. By connecting the cutting block 287 through the spring frame 286, a certain contraction effect is achieved when the cutting block 287 presses down, avoiding excessive cutting and playing a protective role for the object. By opening the plate surface groove 285, the space between the groove and the coating layer is increased to prevent the object from sticking. When the third electric push rod 281 controls the first frame 282 to lift, the resilient rod 283 restores its elasticity, increasing the shaking effect of the component on the coating layer and reducing the adhesion effect with the panel.

[0032] During use, the staff places the panel inside the fixed component 13 within the composite mechanism 1. The fixed component 13 fixes the panel, preventing it from shaking during subsequent operations, avoiding affecting the subsequent coating effect and preventing coating overflow. The PI film material enters from the top of the liquid storage tank 15, and the liquid storage tank 15 plays a certain storage role to facilitate subsequent continuous operations. The heater 16 heats the inside of the liquid storage tank 15 to prevent the internal material from cooling and solidifying during operation, preventing it from affecting subsequent coating operations. The moving frame 14 slides on the surface of the slide rail frame 12, driving the coating mechanism 17 to rub the surface of the panel, thereby achieving the coating operation on the panel. The coating mechanism 17 controls the coating flow rate to avoid excessive coating flow rate and overflow, which affects the coating quality, and at the same time avoids excessive coating thickness affecting the use effect of the panel. After the coating of the panel is completed, the processing mechanism 2 slides on the surface of the slide rail frame 12 towards the fixed component 13. The dryer 23 inside the processing mechanism 2 generates hot air flow, and heats the coating layer from the air outlet housing 25, thereby achieving the effect of drying and curing the coating layer, improving the adsorption effect of the coating layer. After the PI film dries on the surface of the panel, the cutting mechanism 28 presses down on the surface of the panel to cut the possible overflow coating to avoid affecting subsequent processing, and then the panel is taken out from inside the fixed component 13.
