Description

Technical Field

[0001] This utility model relates to the field of anti-glare film coating device, and specifically to a coating device for preparing an anti-glare film. Background Technology

[0002] Anti-glare film is a functional coating that reduces reflected light interference and enhances visual clarity through surface treatment. It forms a uniform nanoscale rough structure on the substrate surface, causing diffuse reflection when light is incident, preventing direct light from entering the eyes and thus reducing glare. Applying anti-glare film requires a special coating device. There are various types of anti-glare film with distinct technical characteristics and a wide range of applications.

[0003] A search revealed a utility model patent with publication number CN220277321U, which discloses a mobile phone back cover coating device. The device includes a body with an upward-opening storage cavity. A discharge cavity penetrating the body is connected to the side wall of the storage cavity. A tray for placing the mobile phone back cover is slidably mounted on the bottom wall of the discharge cavity. Movable plates are detachably connected to both sides of the storage cavity, and rotating plates are detachably connected to the movable plates. A coating spray plate is provided on the end face of the rotating plate. This utility model controls the operation of the coating spray plate through the rotating plate. When not in operation, the spray plate can be rotated and flipped, facilitating material transportation and movement, ensuring that the spray plate does not affect uncoated or already coated equipment. Furthermore, the movable plates allow for easy removal and installation of the spray plate, enabling timely replacement and maintenance, ensuring the normal operation of the coating process.

[0004] Existing anti-glare film coating devices are generally used on flat objects, which typically have at least two sides. In special applications, both sides need to be coated, but existing coating devices can only perform single-sided spraying. This necessitates secondary processing during the coating process, significantly reducing the efficiency of anti-glare film coating.

[0005] Therefore, it is necessary to invent a coating device for preparing an anti-glare film to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a coating device for preparing an anti-glare film. By fixing the side of a straight plate-shaped object within a fixed frame, the device allows for simultaneous coating of both sides of the object with an anti-glare film after both sides are exposed, thus solving the problem of low efficiency in coating anti-glare films on straight plate-shaped objects in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coating device for preparing an anti-glare film layer, comprising a bottom frame, a middle frame installed above the bottom frame, a top frame installed above the middle frame, a storage tank installed above the top frame, a pneumatic diaphragm pump installed above the top frame, and the pneumatic diaphragm pump connected to the storage tank via a pipeline; multiple sets of atomizing nozzles are sequentially installed in both the bottom frame and the top frame, and the atomizing nozzles in the bottom frame and the top frame are arranged opposite to each other, and the atomizing nozzles are connected to the output hose of the pneumatic diaphragm pump;

[0008] The coating component set in the middle frame includes a connecting groove, which is symmetrically opened on the middle frame, bottom frame and top frame respectively, and the connecting groove is connected to the interior of the corresponding middle frame, bottom frame and top frame. A screw is rotatably connected in the connecting groove on one side of the middle frame, and a guide rod is installed in the connecting groove on the other side of the middle frame. The internal structure of the connecting grooves of the middle frame, bottom frame and top frame is the same.

[0009] The fixing component set inside the middle frame includes a fixing frame, which is set inside the middle frame. The fixing frame has connecting cavities on all four sides inside. The connecting cavities have symmetrically formed limit grooves. The connecting seats are set above the connecting cavities. Limit blocks are symmetrically installed on the connecting seats, and the limit blocks are slidably connected to the corresponding limit grooves.

[0010] Preferably, the coating assembly further includes bevel gears, which are sleeved and fixed on each set of screws. The connecting groove of the middle frame is symmetrically rotatably connected to bidirectional bevel gear shafts, and one end of each set of bidirectional bevel gear shafts meshes with the bevel gears inside the middle frame. Furthermore, one end of each set of bidirectional bevel gear shafts meshes with the bevel gears inside the bottom frame and the top frame, respectively.

[0011] Preferably, a servo motor is installed on one side of the middle frame, and the output end of the servo motor is connected to the screw shaft of the middle frame.

[0012] Preferably, each set of screws is screwed with an internally threaded block, and each set of guide rods is slidably connected with a slider.

[0013] Preferably, a sliding seat is installed between the internal threaded block and the slider in the bottom frame and the top frame, and the sliding seat is fixedly connected to the corresponding atomizing nozzle.

[0019] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figure 1-7 The coating apparatus for preparing an anti-glare film layer shown includes a bottom frame 001, a middle frame 101 mounted above the bottom frame 001, a top frame 102 mounted above the middle frame 101, a storage tank 103 mounted above the top frame 102, and a pneumatic diaphragm pump 104 mounted above the top frame 102. The pneumatic diaphragm pump 104 is connected to the storage tank 103 by a pipeline. Multiple sets of atomizing nozzles 105 are sequentially installed in both the bottom frame 001 and the top frame 102. The atomizing nozzles 105 in the bottom frame 001 and the atomizing nozzles 105 in the top frame 102 are arranged opposite to each other. The atomizing nozzles 105 are connected to the output hose of the pneumatic diaphragm pump 104.

[0033] The anti-glare coating material in the storage tank 103 can be transported to the atomizing nozzle 105 by the pneumatic diaphragm pump 104, thereby realizing the anti-glare coating operation.

[0034] The coating component 002 disposed within the middle frame 101 includes a connecting groove 201. The connecting grooves 201 are symmetrically opened on the middle frame 101, the bottom frame 001, and the top frame 102, and the connecting grooves 201 are all connected to the interior of the corresponding middle frame 101, the bottom frame 001, and the top frame 102. A screw 202 is rotatably connected in the connecting groove 201 on one side of the middle frame 101, and a guide rod 209 is installed in the connecting groove 201 on the other side of the middle frame 101. The internal structure of the connecting grooves 201 of the middle frame 101, the bottom frame 001, and the top frame 102 is the same.

[0035] The fixing component 003 set inside the middle frame 101 includes a fixing frame 301. The fixing frame 301 is set inside the middle frame 101. A connecting cavity 302 is opened on all four sides inside the fixing frame 301. A limiting groove 303 is symmetrically opened in the connecting cavity 302. A connecting seat 304 is set on the upper part of the connecting cavity 302. A limiting block 305 is symmetrically installed on the connecting seat 304, and the limiting block 305 is slidably connected to the corresponding limiting groove 303.

[0036] With the cooperation of the limiting groove 303 and the limiting block 305, the connecting seat 304 can slide stably within the connecting cavity 302.

[0037] Furthermore, in the above structure, the coating component 002 also includes a bevel gear 203, which is sleeved and fixed on each set of screws 202. The connecting groove 201 of the middle frame 101 is symmetrically rotatably connected to a bidirectional bevel gear shaft 204, and one end of each set of bidirectional bevel gear shafts 204 meshes with the bevel gear 203 inside the middle frame 101. Additionally, one end of each set of bidirectional bevel gear shafts 204 meshes with the bevel gear 203 inside the bottom frame 001 and the top frame 102, respectively.

[0038] The bidirectional bevel gear shaft 204 allows the screw 202 inside the middle frame 101 to rotate, which in turn drives the screws 202 inside the bottom frame 001 and the top frame 102 to rotate. The screws 202 inside the middle frame 101 have opposite thread directions to the screws 202 inside the bottom frame 001 and the top frame 102, thus allowing the fixed frame 301 to move in the opposite direction to the moving direction of the atomizing nozzle 105, ensuring uniform coating.

[0039] Furthermore, in the above structure, a servo motor 205 is installed on one side of the middle frame 101, and the output end of the servo motor 205 is axially connected to the screw 202 of the middle frame 101.

[0040] The servo motor 205 can be activated to drive the screw 202 to rotate.

[0041] Furthermore, in the above structure, each set of screws 202 is screwed with an internal thread block 207, and each set of guide rods 209 is slidably connected with a slider 208.

[0042] The screw 202 can drive the internal thread block 207 to move.

[0043] Furthermore, in the above structure, a sliding seat 206 is installed between the internal threaded block 207 and the slider 208 in the bottom frame 001 and the top frame 102, and the sliding seat 206 is fixedly connected to the corresponding atomizing nozzle 105.

[0044] The movement of the internal threaded block 207 can cause the sliding seat 206 to move, which in turn drives the atomizing nozzle 105 to move. The cooperation between the slider 208 and the guide rod 209 can ensure that the movement of the sliding seat 206 is more stable.

[0045] Furthermore, in the above structure, a fixing frame 301 is installed between the internal threaded block 207 and the slider 208 inside the middle frame 101.

[0046] The fixed frame 301 can be moved by the internal thread block 207 and slider 208 inside the middle frame 101.

[0047] Furthermore, in the above structure, the fixing component 003 also includes a mating hole 306, which is sequentially formed on one side of the connecting seat 304.

[0048] Furthermore, in the above structure, a sliding rod 307 is slidably connected within the mating hole 306, and a fixing seat 309 is installed on one side of the sliding rod 307, with the fixing seat 309 located within the fixing frame 301.

[0049] By engaging the mating hole 306 and the slide bar 307, the fixed seat 309 can move on one side of the connecting seat 304, thereby allowing the fixed seat 309 to move within the fixed frame 301.

[0050] Furthermore, in the above structure, a spring 308 is installed between the slide rod 307 and the inside of the docking hole 306, a synchronization platform 310 is provided at the bottom inside the connecting cavity 302, an electric push rod 316 is installed between the synchronization platform 310 and the inner wall of the connecting cavity 302, and a stop rod 311 is installed on one side of the synchronization platform 310, and the stop rod 311 is connected through the inner wall of the connecting cavity 302.

[0051] The spring 308 can keep the position of the slide bar 307, so that the fixed seat 309 can be effectively buffered when it moves towards the object, avoiding hard contact and damage to the object. The electric push rod 316 can drive the synchronous table 310 to move, so that the stop bar 311 can pass through the fixed frame 301, allowing the object to be placed on the stop bar 311.

[0052] Furthermore, in the above structure, a fixing plate 312 is symmetrically installed on the inner wall of the connecting cavity 302, and a rotating arm 313 is symmetrically rotatably connected below the fixing plate 312. A sliding cavity 314 is symmetrically opened on both sets of rotating arms 313. A docking rod 315 is symmetrically installed on the synchronous table 310 and the connecting seat 304, and the docking rod 315 is slidably connected to the corresponding sliding cavity 314.

[0053] By rotating the arm 313, the synchronous table 310 retracts along the fixed frame 301 while driving the stop bar 311. At this time, the synchronous table 310 drives the rotating arm 313 to rotate, thereby moving the connecting seat 304 to one side and bringing the fixed seat 309 closer to the object, thus completing the fixation of the side of the straight plate-shaped object. The fixed seat 309 retracts under the action of the spring 308, so that it can automatically adapt to the specific shape of the straight plate-shaped object.

[0054] The working principle of this practical application is as follows:

[0055] Refer to the instruction manual appendix Figure 1-7 By placing the flat object at the center of the fixed frame 301, it can fall above each set of baffles 311. When the electric push rod 316 retracts, the baffles 311 will retract downwards along the flat object. At the same time, the rotating arm 313 rotates, causing the connecting seat 304 to push the fixed seat 309 to fit and fix against the side of the flat object. At this time, the servo motor 205 is started, causing one set of screws 202 to rotate. Simultaneously, under the action of the bidirectional bevel gear shaft 204, the other two sets of screws 202 rotate, thereby realizing the synchronous movement of the two sets of sliding seats 206 and the opposite movement of the fixed frame 301. This allows the anti-glare film material at the spraying point of the atomizing nozzle 105 to be coated on both sides of the flat object, thus achieving simultaneous coating processing on both sides. This structure enables simultaneous processing on both sides of the flat object during the anti-glare film coating process, greatly improving processing efficiency.

[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
