Description
Technical Field
The application relates to the field of 3D display, in particular to a sealant coating system.
Background
In the manufacturing process of the 2D/3D switchable display device, in order to lock the liquid crystal in the liquid crystal layer in the area corresponding to the lens layer (i.e., the effective display area of the liquid crystal panel, also referred to as AA area), before the liquid crystal is arranged in a liquid crystal dripping manner, a sealant is required to be applied to the periphery of the AA area to form a sealant portion, and the upper substrate and the lower substrate are bonded by using the sealant portion, thereby forming the display device.
At present, the coating technology of the sealant mainly comprises the following steps: firstly, screen printing (the formed screen structure is manufactured mainly according to the required coating layout, and then hot stamping is carried out); and secondly, spraying sealant (gradually spraying on the substrate to finally form a desired coating layout).
As a certain tolerance exists in any substrate, the general thickness tolerance is +/-3%, and meanwhile, certain height fluctuation conditions (surface roughness or fine particles and the like caused by a front-stage process) exist on the surface of the substrate, for the second coating mode, a coating machine station detects the appearance condition of the surface of the substrate by using a detector on the self-body in the coating process, and the height of a nozzle is adjusted while coating according to the detection result, so that the whole coated cross-section area is maintained within a controllable specification, and the reliability of a product is not influenced when the product is finally formed into a box. Specifically, when the distance detected by the detector is large, the spray head is adjusted to move downwards, the height of the spray head is reduced, and when the detected distance is small, the spray head is adjusted to move upwards, and the height of the spray head is increased.
In the prior art, the spray head and the detector are both disposed on the coating head of the coating system, and when the plane perpendicular to the height direction is the XY plane (i.e., the surface of the substrate), as shown in fig. 1, the projections of the spray head 2' and the detector 3' on the surface of the substrate 01' are offset on the X axis and the Y axis. This results in a deviation of the position of the spray head applied on the substrate from the position detected by the detector.
The sealant is applied by the application system in the prior art, and the relative positions of the trace applied by the spray head on the substrate and the trace detected by the detector are as shown in fig. 2, where the trace applied by the spray head on the substrate is rectangular (actually, rectangular frame is used for simplicity, and rectangular frame is replaced by rectangle here), four sides are defined as a1, b1, c1 and d1, respectively, the trace detected by the detector is rectangular (actually, rectangular frame is used for simplicity, rectangular frame is replaced by rectangle here), and four sides are defined as a2, b2, c2 and d2, respectively.
It is clear that when the position detected by the detector is on b2 or c2 as shown in fig. 2, the detector is likely to detect the lenticular region 02 'on the substrate, since the height of the lenticular layer is about several tens of micrometers, which is an order of magnitude with respect to the tolerance of the glass substrate, the detector will not ignore the detection result, and, depending on the detection result, the coating system will adjust the position of the spray head so that it moves upward, increasing the height of the spray head to apply the sealant, which eventually results in the sealant on the substrate being too thick here, i.e. the whole cross-sectional area of the region becomes large, and after the upper and lower substrates are finally laminated, the width of the sealant 03' is large as shown in fig. 3, which does not meet the relevant glue width standard or other design standard of the display device.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.
As described in the background art, the width of part of the sealant in the display device prepared by the sealant coating system in the prior art is larger, so as to solve the technical problem as described above, the application provides a sealant coating system.
In an exemplary embodiment of the present application, a sealant application system is provided, and a partial structure schematic diagram of the system is shown in fig. 4 or 5, and the sealant application system includes an application head 1, a spray head 2, a detection unit, and a control unit. Wherein the coating head 1 is provided with a first position, a second position and a third position which are arranged at two sides of the first position; the spray head 2 is arranged at a first position of the coating head 1; the detection unit comprises a detector 3, wherein the second position and the third position of the coating head 1 are used for installing the detector 3, and the detector 3 is used for detecting the distance between the substrate and the detector; the control unit includes an operation control module electrically connected to the detection unit, and the operation control module is configured to control the nozzle to operate according to a detection result of the detector 3 mounted at the second position or according to a detection result of the detector 3 mounted at the third position.
By means of the technical scheme, the detector is arranged at the second position and/or the third position on the coating head, namely when the detection unit is one detector, the detector is arranged at the second position or the third position, when the detection unit comprises two or more detectors, at least one detector is respectively arranged at the second position, one detector is arranged at the third position, the work control module in the control unit can control the spray head to work according to the detection result of the detector positioned at the second position or the third position according to actual conditions, and then the spray head can work according to the detection result of the detector projected to be not positioned in the grating area, so that the problem caused by too wide width of the sealant is avoided.
In one embodiment of the present application, the operation control module is configured to control the operation of the detector mounted at the second position and the operation of the detector mounted at the third position, or the operation of the detector mounted at the second position and the operation of the detector mounted at the third position, and the head 2 is operated according to a detection result of the detector being operated. For example, when the position detected by the detector at the second position is close to the grating area on the detection substrate, the operation control module controls the detector at the second position to stop operating and controls the detector at the third position to operate, so that the detection position of the detector avoids the grating area.
In addition, when only one detector is included in the detection unit, the detector needs to be installed in the second position or the third position, i.e., when the detector is required to be in the second position, the detector is installed in the second position, and when the detector is required to be in the third position, the detector is installed in the third position.
In an embodiment of the application, the control unit further includes a first position control module, where the first position control module is electrically connected to the spray head and the detector, and the first position control module is configured to control the spray head to move synchronously with the detector that is working, so as to perform the work of coating and detecting at the same time.
In order to better control the spray head and the detector synchronously, in one embodiment of the present application, the first position control module is electrically connected to the coating head, so as to control the spray head and the detector mounted on the coating head.
In another embodiment of the present application, the sealant applying system further includes a server electrically connected to the first position control module and the operation control module, the server controlling the operation control module according to a signal transmitted from the first position control module, the server starting the operation control module when the first position control module transmits a signal for the detector to reach a predetermined position or a signal for the nozzle to reach a predetermined position to the server, the operation control module controlling the detector to reach the predetermined position to stop operation, for example, controlling the detector mounted at the second position to stop operation when the detector to reach the predetermined position is mounted at the second position, and controlling the detector mounted at the third position to operate; when the first position control module transmits a signal that the detector does not reach a predetermined position or a signal that the head does not reach a predetermined position to the server, the server does not activate the operation control module.
In order to further facilitate the operation of the operation control module, in one embodiment of the present application, the first position control module sends a signal that the detector reaches a predetermined position to the server, when the position of the projection of the detector on the detection substrate is located at the grating area on the detection substrate or at the junction between the grating area and the detection substrate, the detector is considered to reach the predetermined position, and the server controls to start the operation of the operation control module, and the operation control module controls the detector located at the predetermined position to stop operating, for example, when the detector located at the predetermined position is mounted at the third position, controls the detector mounted at the third position to stop operating, and controls the detector mounted at the second position to operate.
The predetermined position of the detector in the present application is not limited to the above description, and a person skilled in the art may determine the predetermined position according to specific conditions such as the shape of the detection substrate, the size detection of the detection substrate, the size of the grating region provided on the detection substrate, the shape of the grating region, the application shape of the sealant, and/or the application size of the sealant. Likewise, the person skilled in the art can determine the predetermined position of the spray head on the basis of some of the conditions described above.
For example, as shown in fig. 6, when the shapes of the detection substrate 01 and the lens layer (i.e., the grating region 02) are rectangular, the application direction is assumed to be counterclockwise, that is, the detector at one position is firstly used to work synchronously with the spray head, the motion track of the spray head is from a3 to d3, and the motion track of the detector is from a4 to d4. When the spray head is about to reach the corner of d3 and c3 or just reaches the corner of d3 and c3, the other detector can be started to work, namely the detector at the other position is controlled to work, the movement track of the spray head passes through c4 to b4, and the movement track of the spray head passes through c3 to b3, when the spray head is about to reach the corner of b3 and a3 or just reaches the corner of b3 and a3, the detector at the other position can be started to work, and the process is circulated until coating is completed. I.e. in this embodiment, there are two predetermined positions, near the corner of d3 and c3 and near the corner of b3 and a 3. The first position control module can send the preset position of the spray head or the preset position of the detector to the server, and the server judges whether to start the work control module according to the corresponding position information.
In yet another embodiment of the present application, as shown in fig. 5, the detecting unit includes a detector 3, the coating head 1 includes a substrate 11 and a guide rail 12, and the first position is located on the substrate 11; the guide rail 12 is provided on the base 11, and the second position and the third position are both located on the guide rail 12. By the arrangement of the guide rail, the detector can be moved along the guide rail from the second position to the third position or from the third position to the second position.
In order to further prevent the arrangement of the guide rail from affecting the operation of the spray head, in one embodiment of the present application, the guide rail 12 is arranged around the first position as shown in fig. 5.
The shape of the projection of the guide rail on the substrate can be rectangular, circular, triangular or other shapes, for example, a non-closed graph, for example, a straight line of two rubbers, and a person skilled in the art can select a guide rail with a proper shape according to practical situations.
In one embodiment of the present application, as shown in fig. 5, the projection of the guide rail 12 on the base 11 is a rectangular frame. This allows for better control of the movement of the detector.
In order to control the actuation of the working module more precisely, in one embodiment of the present application, the control unit further comprises a second position control module, which is electrically connected to the detector and is configured to control the detector to move between the second position and the third position.
In another embodiment of the present application, the server is further electrically connected to the second position control module, the first position control module sends a signal that the detector reaches a predetermined position or a signal that the nozzle reaches a predetermined position to the server, the server starts the second position control module, and when the second position control module sends a signal that the detector position movement is completed to the server, the server controls the operation control module to start.
In yet another embodiment of the present application, as shown in fig. 4, the detecting unit includes two detectors 3, and the two detectors 3 are respectively disposed at a second position and a third position. When one of the detectors is required to work, the other detector is only required to be controlled to be turned on, and the other detector is not required to be moved from the second position or the third position to the other position, so that the detection unit can more efficiently and rapidly coat the sealant.
In order to adjust the amount of the sealant coated on the detection substrate in real time, so that the whole cross-sectional area of the coated sealant is maintained within a controllable specification, and the performance of the product is not affected while the product is finally formed into a box. When the detected height of the detection substrate is higher, the spray head is adjusted to move upwards, and when the detected height of the detection substrate is lower, the spray head is adjusted to move downwards.
The operation control module in the present application may control whether the detector operates, or control which position of the detector transmits the corresponding detection result to the third position control module, or control whether the spray head operates according to the detection result of the detector mounted at the second position, or according to the detection result of the detector mounted at the third position, by other suitable methods.
For the first way in the upper paragraph, i.e. for "control whether the detector is active", it is necessary to control the operation of the detector in one of the second and third positions, and the detector in the other position is inactive. For the second way in the upper paragraph, i.e. for "which position detector is controlled to send the corresponding detection result to the third position control module, or by other suitable means", the two position detectors may be operated simultaneously, or only the corresponding detector that is controlled to send the detection result to the third position control module, there is a specific embodiment for this way: the detector at which position (namely the second position or the third position) is controlled to be electrically connected with the third position control module, so that the detection result of the detector at the corresponding position is sent to the third position control module.
In the above paragraph, the mentioned case of "the detectors at two positions can be operated simultaneously" is only applicable to the case where two detectors are included in the detection unit in the sealant coating system, and is not applicable to the case where the detection unit includes only one detector.
In a specific embodiment of the present application, the operation control module controls the detector installed at the second position to send a corresponding detection result to the third position control module, or the operation control module controls the detector installed at the third position to send a detection result to the third position control module.
