Description

Technical Field

[0001] This application relates to the field of coating equipment technology, and more particularly to a coating equipment. Background Technology

[0002] In the production process of electrochromic films, coating equipment is mainly used to coat the surface of the substrate with a layer of coating with specific functions, and then obtain the desired film after drying. To ensure that the coating thickness is the same throughout the substrate, a transmittance monitoring device is needed to monitor the transmittance, and then adjust the conveying speed of the feeding device of the coating equipment according to the transmittance. In traditional coating equipment, a transmittance monitoring device is usually installed at the unloading end of the film to monitor whether the thickness of the film is within the expected range. However, this can easily lead to the inability to monitor the film thickness in real time over a long range between the feeding and unloading ends. This results in uneven film thickness and reduced production yield. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a coating device that can improve the thickness uniformity and production yield of the film.

[0040] Reference Figures 1 to 4 As shown, the coating equipment involved in the embodiments of this application has a first direction x, and the coating equipment includes: a feeding device 100, a discharging device 200, a baking device 300, a light transmittance monitoring device 400, and a control device 500.

[0041] Specifically, the feeding device 100 and the unloading device 200 are spaced apart along the first direction x; the baking device 300 is disposed between the feeding device 100 and the unloading device 200, and the feeding device 100 is used to feed the film along the first direction x via the baking device 300 to the unloading device 200; the transmittance monitoring device 400 is disposed on the path of the film being conveyed along the first direction x, and is used to monitor the first transmittance of the film at the feeding device 100; both the feeding device 100 and the transmittance monitoring device 400 are electrically connected to the control device 500, and the transmittance monitoring device 400 is used to send a signal of the first transmittance to the control device 500. When the value of the first transmittance received by the control device 500 exceeds the first preset range value, the control device 500 controls the feeding device 100 to adjust the conveying speed along the first direction x.

[0042] It should be noted that the first direction x is Figure 1 as well as Figure 2 The direction indicated by x in the middle.

[0043] In the coating equipment of this application, when coating a film, the film can be conveyed along the first direction x by the feeding device 100 to the unloading device 200 via the baking device 300, so that the film is coated and baked by the baking device 300 to obtain the desired film. In this process, the first transmittance of the film at the feeding device 100 can be monitored by the transmittance monitoring device 400. When the value of the first transmittance received by the controller exceeds the first preset range value, the controller can control the feeding device 100 to adjust the conveying speed along the first direction x, thereby adjusting the conveying speed of the film at the feeding device 100, thereby adjusting the coating thickness on the film, and further controlling the film thickness within the expected thickness range. In this way, the problem that the film thickness over a long range between the feeding device 100 and the unloading device 200 cannot be monitored in real time can be solved, thereby improving the film thickness uniformity and production yield.

[0044] Reference Figure 3 as well as Figure 4 As shown, the transmittance monitoring device 400 includes a first transmittance monitoring device 401 and a second transmittance monitoring device 402. Both the first transmittance monitoring device 401 and the second transmittance monitoring device 402 are electrically connected to the control device 500. The first transmittance monitoring device 401 is located at the feeding device 100 and is used to monitor the first transmittance and send a signal of the first transmittance to the control device 500. The second transmittance monitoring device 402 is located at the unloading device 200 and is used to monitor the second transmittance of the film at the unloading device 200 and send a signal of the second transmittance to the control device 500. The second transmittance has a second preset range value. The control device 500 obtains the first preset range value based on the difference between the first transmittance and the second transmittance and the second preset range value.

[0045] In this embodiment, when the second transmittance at the feeding device 200 is within the second preset range, the film thickness is within the expected thickness range. It is understood that the coating thickness of the coated film will change before and after baking due to the difference in dryness and wetness. The coating thickness of the dry film is less than that of the wet film. Therefore, the transmittance of the dry film is greater than that of the wet film. Thus, the difference between the first and second transmittance can be used to obtain the transmittance change, which in turn can be used to obtain the thickness change of the film after baking by the baking device 300. Then, the first preset range value is obtained based on the transmittance change and the second preset range value. When the first transmittance at the feeding device 100 is within the first preset range, the transmittance of the baked film can be made to be within the second preset range, further ensuring that the thickness of the baked film is within the expected thickness range. In this way, the thickness of the film can be monitored in real time from the feeding device 100, thereby improving the production yield of the film.

[0046] Reference Figure 5 as well as Figure 8 As shown, the transmittance monitoring device 400 includes a bracket 410 and a transmittance monitoring component 420. The bracket 410 is provided at both the feeding device 100 and the unloading device 200, and the transmittance monitoring component 420 is mounted on the bracket 410.

[0047] In this embodiment, the transmittance monitoring component 420 can be supported by the bracket 410. Each bracket 410 is provided with a transmittance monitoring component 420. The transmittance monitoring component 420 on the bracket 410 at the feeding device 100 is used to monitor the first transmittance in real time, and the transmittance monitoring component 420 on the bracket 410 at the unloading device 200 is used to monitor the second transmittance in real time, so as to obtain the real-time transmittance signals of the first transmittance and the second transmittance.

[0048] Reference Figure 5 As shown, the coating equipment also has a second direction y, which intersects with the first direction x, as referenced. Figure 6 The transmittance monitoring component 420 includes an emitter 421 and a receiver 422. The emitter 421 and the receiver 422 are spaced apart along the second direction y to define a feeding space 423 for the film to pass through. The emitter 421 is used to emit transmitted light to the film, and the receiver 422 is used to receive the transmitted light.

[0049] It should be noted that the second direction y is Figure 1 as well as Figure 2 The direction indicated by y in the middle.

[0050] It should be noted that the transmittance detection component located at the feeding device 100 is the first transmittance detection component, and the ratio between the transmitted light received by the receiver 422 of the first transmittance detection component and the transmitted light emitted by the emitter 421 is the first transmittance. The transmittance detection component located at the unloading device 200 is the second transmittance detection component, and the ratio between the transmitted light received by the receiver 422 of the second transmittance detection component and the transmitted light emitted by the emitter 421 is the second transmittance.

[0051] In this embodiment, the diaphragm can pass through the feeding space 423 so that the transmitter 421 and the receiver 422 are located on opposite sides of the diaphragm along the second direction y. In this way, the transmitted light emitted by the transmitter 421 to the diaphragm can be transmitted through the diaphragm to the receiver 422. The transmittance can be obtained by the transmittance of the transmitted light received by the receiver 422, thereby obtaining the transmittance of the diaphragm at the transmittance monitoring component 420.

[0052] Example 1

[0053] Reference Figure 5 As shown, in Embodiment 1, the coating equipment also has a third direction z, which intersects with the first direction x. The transmittance monitoring device 400 also includes a driving member 430, which is connected to the transmittance monitoring component 420 and is used to drive the transmittance monitoring component 420 to move along the third direction z.

[0054] It should be noted that the third party is z. Figure 1 as well as Figure 2 The direction indicated by z in the middle.

[0055] In this embodiment, the transmittance monitoring component 420 can be driven to move along the third direction z, that is, along the width direction of the film, so that the transmittance monitoring component 420 can be applied to films of different widths, thereby improving the applicability of the transmittance monitoring device 400.

[0056] Specifically, refer to Figure 7 As shown, the transmittance monitoring device 400 also includes multiple guide components 450. Each guide component 450 includes a guide rail 451 and a guide member 452. The multiple guide rails 451 are spaced apart on the bracket 410 along the second direction y and extend along the third direction z. Each guide member 452 is connected to a guide rail 451. The drive member 430 is connected to each guide member 452 and drives the multiple guide members 452 to move simultaneously along the third direction z relative to the guide rail 451. The transmitter 421 is connected to a guide member 452, and the receiver 422 is connected to a guide member 452. In this way, the guide member 452 can guide the movement of the transmitter 421 and the receiver 422 along the third direction z, so that the transmitter 421 and the receiver 422 can move along the third direction z.

[0057] Reference Figure 5 As shown, there are multiple transmittance monitoring components 420 and driving components 430. The multiple transmittance monitoring components 420 are spaced apart along the third direction z. The driving component 430 is connected to at least one transmittance monitoring component 420 and is used to drive the transmittance monitoring component 420 connected thereto to move along the third direction z.

[0058] Specifically, in this embodiment, two transmittance monitoring components 420 and two driving components 430 are provided. The two driving components 430 are respectively disposed on both sides of the membrane along the third direction z. Each driving component 430 is connected to one transmittance monitoring component 420, so that the two transmittance monitoring components 420 move on both sides of the membrane along the third direction z, thereby realizing the monitoring of transmittance of the membrane at multiple positions along the third direction z through the two transmittance monitoring components 420.

[0059] In this embodiment, since multiple transmittance monitoring components 420 are spaced apart along the third direction z, the transmittance of the film at multiple positions along the third direction z can be monitored through multiple transmittance monitoring components 420, thereby improving the accuracy of transmittance monitoring of the film. Furthermore, since the driving component 430 can drive the transmittance monitoring components 420 connected to it to move along the third direction z, each transmittance monitoring component 420 can be applied to films of different widths, thereby improving the applicability of the transmittance monitoring device 400.

[0060] Example 2

[0061] Reference Figure 8 as well as Figure 9 As shown, the transmittance monitoring device 400 also includes a fixing component 440, which is mounted on the bracket 410 and extends along the third direction z. There are multiple transmittance monitoring components 420, which are spaced apart along the third direction z and mounted on the fixing component 440.

[0062] In this embodiment, multiple transmittance monitoring components 420 can be spaced apart on the fixing component 440 along the third direction z. In this way, the multiple transmittance monitoring components 420 can be fixed by the fixing component 440, so that the transmittance of the film can be monitored at multiple positions along the third direction z of the film by the multiple transmittance monitoring components 420, thereby improving the accuracy of transmittance monitoring of the film.

[0063] Reference Figure 9 As shown, the fixing component 440 includes a fixing member 441 and a connecting member 442. The fixing member 441 extends along the third direction z. The light transmittance monitoring component 420 is disposed on the fixing member 441. Both ends of the fixing member 441 along the third direction z are respectively connected to a connecting member 442. The connecting member 442 is connected to the bracket 410.

[0064] In this embodiment, since the fixing member 441 extends along the third direction z, multiple transmittance monitoring components 420 can be spaced along the third direction z on the fixing member 441 to fix the multiple transmittance monitoring components 420. Since the two ends of the fixing member 441 along the third direction z are respectively connected to a connector 442, and the connector 442 is connected to the bracket 410, the two ends of the fixing member 441 along the third direction z can be connected to the bracket 410 through the connector 442, thereby fixing the fixing member 441.

[0065] Continue to refer to Figure 9As shown, a plurality of first connecting holes 4411 are provided at one end of the fastener 441 connected to the connector 442. The plurality of first connecting holes 4411 are arranged around a third direction z. A plurality of second connecting holes 4421 are provided at the connection between the connector 442 and the fastener 441. The fastener 441 rotates relative to the connector 442 around a third direction z so that the second connecting hole 4421 communicates with a first connecting hole 4411. The fastening assembly 440 also includes a plurality of first fasteners 443, which pass through the interconnected first connecting holes 4411 and second connecting holes 4421.

[0066] In this embodiment, when the fixing member 441 rotates relative to the connecting member 442 about a third direction z to a preset angle, each second connecting hole 4421 on the connecting member 442 is connected to a first connecting hole 4411 on the fixing member 441. Then, the first fastener 443 is inserted into the interconnected first connecting hole 4411 and second connecting hole 4421. The connection between the fixing member 441 and the connecting member 442 is achieved through the cooperation of the first fastener 443 with the first connecting hole 4411 and the second connecting hole 4421. In this way, the fixing member 441 can rotate relative to the connecting member 442 about a third direction z to any angle, so that the angle of the feeding space 423 can be adapted to the conveying angle of the film, thereby improving the applicability of the light transmittance monitoring device 400.

[0067] Specifically, in this embodiment, the walls of the first connecting hole 4411 and the second connecting hole 4421 are provided with internal threads, and the outer wall of the first fastener 443 is provided with external threads. The first fastener 443 is connected to the first connecting hole 4411 and the second connecting hole 4421 by threads.

[0068] Specifically, refer to Figure 10 As shown, the fixing member 441 includes a first fixing part 4412 and a second fixing part 4413. Both the first fixing part 4412 and the second fixing part 4413 extend along a third direction z, and the first fixing part 4412 and the second fixing part 4413 are spaced apart along a second direction y to define a feeding space 423. The transmitting member 421 is disposed on the first fixing part 4412, and the receiving member 422 is disposed on the second fixing part 4413. The fixing member 441 also includes a connecting part 4414. Both ends of the first fixing part 4412 and the second fixing part 4413 along the third direction z are connected to a connecting part 4414. Each connecting part 4414 is connected to a connecting member 442, so that the first fixing part 4412 and the second fixing part 4413 are connected to the connecting member 442 through the connecting part 4414.

[0069] Reference Figure 9As shown, the fixing component 440 also includes a second fastener 444, which is connected to the fixing member 441 and is disposed at the end where the fixing member 441 is connected to the connector 442. A plurality of first connecting holes 4411 are arranged around the second fastener 444 in a third direction z. The connector 442 is also provided with a third connecting hole 4422, and a plurality of second connecting holes 4421 are arranged around the third connecting hole 4422 in a third direction z. The second fastener 444 passes through the third connecting hole 4422 and is interference-fitted with the hole wall of the third connecting hole 4422.

[0070] In this embodiment, since multiple first connecting holes 4411 surround the second fastener 444 in a third direction z, and multiple second connecting holes 4421 surround the third connecting hole 4422 in a third direction z, when the fixing member 441 rotates relative to the connecting member 442 in a third direction z, the second fastener 444 can always be inserted into the third connecting hole 4422. When it is necessary to adjust the angle of the fixing member 441, the first fastener 443 can be removed from the first connecting hole 4411 and the second connecting hole 4421. This allows the fastener 441 to rotate relative to the connector 442 about a third direction z. Since the second fastener 444 is interference-fitted with the wall of the third connecting hole 4422, the fastener 441 can be prevented from separating from the connector 442 during the adjustment of the fastener 441. This prevents the fastener 441 from falling off, making it easier to adjust the fastener 441 and also preventing damage to the light transmittance monitoring component 420 on the fastener 441.
