Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display device and a method for assembling the display device. Background Technology

[0002] Currently, the appearance design of display devices is one of the most important factors influencing consumers' purchasing decisions. As the demand for high-quality viewing experiences increases, displays are trending towards ultra-narrow bezels, resulting in increasingly narrower bezels in their designs.

[0020] The adhesive is used to bond the display panel and the first support frame.

[0021] In some embodiments, the display device further includes adhesive lines;

[0025] According to a second aspect of the present disclosure, a method for assembling a display device is provided, comprising:

[0026] The back panel of the display device is connected to the second connecting frame that supports the outer frame of the display device.

[0027] The film structure of the display device is assembled between the first support frame and the second support frame of the supporting outer frame, such that there is a gap between the film structure and the first connecting frame of the supporting outer frame;

[0028] The display panel of the display device is assembled onto the side of the first support frame away from the second support frame;

[0029] The gap is used to provide space for the expansion of the diaphragm structure.

[0030] In some embodiments, assembling the display panel of the display device onto the side of the first support frame opposite to the second support frame includes:

[0031] Multiple positioning points are laser-engraved on the adhesive surface of the first support frame on the side opposite to the second support frame.

[0039] When the first fitted data is within the first preset error range, the dispensing head of the dispensing device is controlled to dispense the adhesive onto the dispensing surface based on the fitted trajectory formed by the first fitted data.

[0040] In some embodiments, the fitted trajectory includes at least one corner position; controlling the dispensing head of the dispensing device to dispense the adhesive onto the dispensing surface based on the fitted trajectory formed by the first fitted data includes:

[0041] When the dispensing head is controlled to dispense adhesive along the fitted trajectory, if the dispensing head is detected to have moved to the corner position, the movement speed of the dispensing head is reduced to a first set speed, and the amount of adhesive supplied by the dispensing head is reduced, so that the adhesive is dispensed on the dispensing surface.

[0042] If it is detected that the dispensing head has been adjusted from the first direction of movement to the second direction of movement at the corner position, the movement speed of the dispensing head is increased to the second set speed, and the glue supply of the dispensing head is increased, so that the adhesive is dispensed on the dispensing surface.

[0048] In some embodiments, controlling the dispensing head to dispense the adhesive onto the dispensing surface based on the second fitted data includes:

[0049] Based on the second fitted data, the actual distance from the dispensing head to different positions on the dispensing surface is determined;

[0050] If the actual distance differs from the preset desired distance, the position of the dispensing head is adjusted.

[0051] The adhesive is applied to the adhesive surface using the adjusted dispensing head.

[0052] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0053] In this embodiment, the backplate is connected to the second connecting frame, and the gap between the diaphragm structure and the first connecting frame serves as an expansion gap, providing space for the expansion of the diaphragm structure. In other words, no additional components are provided between the diaphragm structure and the first connecting frame in this embodiment. Therefore, while reducing the BM region to achieve a narrower frame width, the expansion gap of the diaphragm structure can be increased, reducing the likelihood of the diaphragm structure warping during expansion.

[0054] Furthermore, in this embodiment, no additional components are provided in the gap between the diaphragm structure and the first connecting frame, which makes the diaphragm structure closer to the first connecting frame. This not only increases the pressing area of ​​the first support frame pressing the diaphragm structure and improves the reliability of the display device, but also reduces the occurrence of light at the gap when viewing from the display side of the display panel, thus improving the viewing experience.

[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0074] This disclosure provides a display device. Figure 1 This is a schematic diagram illustrating the structure of a display device according to an exemplary embodiment of the present disclosure. For example... Figure 1 As shown, the display device includes a supporting frame 100, a display panel 200, a diaphragm structure 300, and a back plate 400. The supporting frame 100 has a first connecting frame 101, a first support frame 102, a second support frame 103, and a second connecting frame 104. The first support frame 102 and the second support frame 103 are connected side-by-side to the same side of the first connecting frame 101 along a first direction A and can both extend along a second direction B. The second direction B is different from the first direction A. The second connecting frame 104 is connected to the side of the second support frame 103 away from the first connecting frame 101. The display panel 200 is disposed on the side of the first support frame 102 away from the second support frame 103. The diaphragm structure 300 is disposed between the first support frame 102 and the second support frame 103. The back plate 400 is connected to the second connecting frame 104. The gap between the diaphragm structure 300 and the first connecting frame 101 provides space for the expansion of the diaphragm structure 300.

[0075] In this embodiment of the disclosure, the display device is used to provide a viewing experience through the display function of the display panel. The display device includes television equipment, monitors, tablet computers, and laptop devices, etc., and this embodiment of the disclosure does not limit this to any particular type.

[0076] For example, the display device includes a television device. In the television device of this disclosure embodiment, the bending arm of the back plate is not disposed between the diaphragm structure and the first connecting frame, but rather the back plate is connected to the second connecting frame, and the gap between the diaphragm structure and the first connecting frame is used as an expansion gap to provide space for the expansion of the diaphragm structure. That is to say, no additional components are disposed between the diaphragm structure and the first connecting frame in this disclosure embodiment.

[0077] In this embodiment, the supporting frame includes a first connecting frame, a second connecting frame, a first supporting frame, and a second supporting frame. The first connecting frame, the second connecting frame, the first supporting frame, and the second supporting frame can be integrally formed to constitute the supporting frame.

[0078] The first support frame and the second support frame are connected side-by-side to the same side of the first connecting frame along a first direction. This first direction may include a direction perpendicular to the display surface of the display panel.

[0079] It should be noted that the first connecting frame can be an annular frame with an opening, and the first support frame and the second support frame can be located within the annular space enclosed by the first connecting frame.

[0080] Both the second support frame and the first support frame extend along a second direction. This second direction differs from the first direction in that there is an angle between the first and second directions, which can be an acute angle, a right angle, or an obtuse angle.

[0081] For example, the angle between the first direction and the second direction is a right angle. When the first direction is perpendicular to the display surface of the display panel, the second direction may be parallel to the display surface of the display panel.

[0082] The aforementioned display panel is mounted on the first support frame. In other words, the first support frame is used to support the display panel.

[0083] It should be noted that the display panel, the first support frame, and the second support frame can be stacked in the first direction.

[0084] For example, the display panel may include: a liquid crystal panel (Open Cell, OC), an organic light-emitting diode display panel, a light-emitting diode display panel, a cathode ray tube display panel, or a quantum dot display panel, etc., and the embodiments disclosed herein are not limited thereto.

[0085] In this embodiment of the disclosure, the display panel and the first support frame can be fixed by different fixing methods.

[0086] For example, the first support frame and the display panel can be fixed by means of foam adhesive or liquid adhesive.

[0087] In this embodiment, such as Figure 1 As shown, the display device also includes a back cover 500. The back cover 500 can be connected to the first connecting frame 101. The cavity space enclosed by the back cover 500 can be closed by the display panel 200 and the first connecting frame 101; the display panel 200 covers the opening of the cavity space. Here, the first connecting frame can be the display outer frame of the display device.

[0088] The aforementioned diaphragm structure is disposed between the first support frame and the second support frame. Here, the diaphragm structure can be connected to the second support frame, that is, the second support frame can be used to support the diaphragm structure.

[0089] It should be noted that the film structure is an optical film structure, which can be used to adjust the display brightness of the display panel. For example... Figure 1As shown, the diaphragm structure 300 can be formed by stacking a diffuser plate 301 and a brightness enhancement film 302 along the first direction A.

[0090] The diffuser plate 301 is connected between the brightness enhancement film 302 and the second support frame 103. The diffuser plate 301 is used to scatter incident light; the brightness enhancement film 302 is used to increase light intensity.

[0091] The aforementioned backplate is connected to the second connecting frame. The second connecting frame can extend away from the first support frame.

[0092] Here, the back panel and the second connecting frame can be fixedly connected to achieve fixed support of the outer frame through the back panel.

[0093] It should be noted that the back plate does not extend into the gap between the diaphragm structure and the first connecting frame. That is, in the second direction, the gap between the diaphragm structure and the first connecting frame does not accommodate other additional devices, but serves as an expansion gap to provide space for the expansion of the diaphragm structure.

[0094] Here, the diaphragm structure expands when heated. By setting an expansion gap to accommodate the expanded diaphragm structure, the warping and lifting of the diaphragm structure can be reduced.

[0095] In this embodiment of the disclosure, the surface of the first support frame facing the diaphragm structure is pressed against the diaphragm structure.

[0096] It should be noted that since no additional components are accommodated in the gap between the diaphragm structure and the first connecting frame, the diaphragm structure will be closer to the first connecting frame in the second direction. This not only increases the pressing area of ​​the diaphragm structure against the first support frame, improving the reliability of the display device, but also reduces the amount of light appearing at the gap when viewing from the display side of the display panel, thus improving the viewing experience.

[0097] To buffer the compression effect of the first support frame on the diaphragm structure, embodiments of this disclosure also propose providing a buffer in the display device. In some embodiments, such as Figure 1 As shown, the display device also includes a buffer 600; the buffer 600 is disposed between the diaphragm structure 300 and the first support frame 102 and connected to the first support frame 102.

[0098] In this embodiment of the disclosure, the buffer is used to buffer the force exerted by the first support frame on the diaphragm structure.

[0099] It should be noted that the buffer and the diaphragm structure can be spaced apart or in contact, and the embodiments disclosed herein do not impose any restrictions on this.

[0100] For example, the cushioning element includes cushioning foam. Of course, the cushioning element may also be composed of other cushioning materials, and this disclosure does not limit this.

[0101] In related technologies, Figure 2 This is a schematic diagram illustrating the structure of a conventional display device according to an exemplary embodiment. For example... Figure 2 As shown, the extension arm 11 of the back panel in the display device is disposed between the diaphragm 13 and the outer frame 12. Thus, in the process of narrowing the bezel width 15 by reducing the black matrix (BM) region 14, there may be problems such as insufficient expansion gap S1 of the diaphragm 13 and small pressing area of ​​the diaphragm 13.

[0102] Based on this, the present disclosure proposes that the backplate is connected to the second connecting frame, and the gap between the diaphragm structure and the first connecting frame serves as an expansion gap to provide space for the expansion of the diaphragm structure. In other words, compared to related technologies that place the extension arm of the backplate between the diaphragm structure and the first connecting frame, the present disclosure does not include any additional components between the diaphragm structure and the first connecting frame; that is, the design of the backplate extension arm is eliminated in the gap. This increases the expansion gap of the diaphragm structure while reducing the frame width in the BM region, thus reducing the likelihood of the diaphragm structure warping during expansion.

[0103] Furthermore, the elimination of the backplate extension arm design in the gap in this embodiment may bring the diaphragm structure closer to the first connecting frame. This not only increases the pressing area of ​​the first support frame pressing the diaphragm structure and improves the reliability of the display device, but also reduces the amount of light appearing at the gap when viewing from the display side of the display panel, thus improving the viewing experience.

[0104] In some embodiments, such as Figure 1 As shown, the back plate 400 has a first back plate portion 401 extending along the second direction B and a second back plate portion 402 extending in a direction away from the first support frame 102; the first back plate portion 401 is connected between the diaphragm structure 300 and the second support frame 103; the second back plate portion 402 is connected between the first back plate portion 401 and the second connecting frame 104.

[0105] In this embodiment, the first backplate is connected between the diaphragm structure and the second support frame. The diaphragm structure is disposed between the first and second support frames, and the first support frame supports the display panel. Therefore, the display panel, the first support frame, the diaphragm structure, the first backplate, and the second support frame can be stacked along a first direction.

[0106] It should be noted that the length of the first back panel along the second direction may be less than or equal to the length of the second support frame along the second direction.

[0107] In this embodiment of the present disclosure, both the second connecting frame and the second back plate can extend away from the first support frame, so that the second back plate and the second connecting frame can be better fixed together.

[0108] In some embodiments, such as Figure 1 As shown, the second back plate portion 402 has a first fixing hole 404, the first fixing hole 404 having a raised edge 403; the second connecting frame 104 has a second fixing hole 105; the second fixing hole 105 surrounds the raised edge 403 of the first fixing hole 404, and the first fixing hole 404 is aligned with the second fixing hole 105; the display device also includes a fastener 700; the fastener 700 passes through the first fixing hole 404 and the second fixing hole 105 and is connected to the second connecting frame 104.

[0109] In this embodiment, the protruding edge of the first fixing hole can be formed by protruding towards the second connecting frame. The size of the protruding edge can be set according to the actual situation, and this embodiment does not limit it.

[0110] The aforementioned fastener passes through the first and second fixing holes to secure the second back plate and the second connecting frame. Here, the dimensions of the first and second fixing holes are adapted to the dimensions of the fastener passing through the two fixing holes, so that the fastener can better secure the second back plate and the second connecting frame.

[0111] It should be noted that the fasteners may include screws, which are used to secure the second back plate and the second connecting frame.

[0112] In this embodiment, the second fixing hole surrounds the protruding edge, and the second fixing hole is aligned with the first fixing hole. That is, the straightness of the plane of the connecting surface between the protruding edge and the second fixing hole is related to the straightness of the plane of the first support frame in the support outer frame. In other words, by controlling the straightness of the plane of the connecting surface between the protruding edge and the second fixing hole, the straightness of the plane of the first support frame in the support outer frame can be adjusted.

[0113] It is understood that by setting a raised edge so that the second fixing hole surrounds the raised edge, the planar straightness of the first support frame in the support outer frame can be adjusted to improve the assembly effect of the support outer frame.

[0114] In some embodiments, such as Figure 1 As shown, the display device also includes an adhesive component 900; the adhesive component 900 is applied to the side of the first support frame 102 opposite to the second support frame 103 by dispensing adhesive through a dispensing device; the adhesive component 900 is used to bond the display panel 200 and the first support frame 102.

[0115] In this embodiment of the disclosure, the display panel can be directly fixed to the supporting frame using an adhesive.

[0116] It should be noted that the adhesive can be applied to the adhesive surface of the first support frame in a liquid state using a dispensing device, and the display panel and the first support frame can be effectively fixed after the adhesive has cured.

[0117] Here, the adhesive includes various adhesives, which may include, but are not limited to, UV adhesives or hot melt adhesives, etc., and the embodiments disclosed herein do not limit this.

[0118] For example, when the frame width narrows, the area for setting the adhesive between the OC and the first support frame also narrows, resulting in a reduction in the effective bonding area of ​​the OC and consequently quality problems such as OC detachment. Currently, foam tape is commonly used to fix the OC and the first support frame. However, when the width of the BM area of ​​the OC is shortened to less than 3mm, the mechanical properties of the foam tape cannot meet the bonding requirements of the OC, increasing the risk of OC detachment.

[0119] Based on this, the present disclosure proposes to use a dispensing device to dispense adhesive onto the side of the first support frame opposite to the second support frame, and then use the adhesive to bond the display panel and the first support frame. Thus, by controlling the dispensing device to dispense adhesive, the present disclosure not only improves the reliability of the fixation between the first support frame and the display panel, but also enables rapid connection between dispensing and assembly.

[0120] In some embodiments, such as Figure 1 and Figure 3 As shown, the display device also includes an adhesive line 800; the adhesive line 800 is disposed along the connection edge between the display panel 200 and the first support frame 102 and is exposed on at least one side of the support frame 100.

[0121] In this embodiment of the present disclosure, the adhesive line displayed on the outside of the support frame is subjected to external force, which can weaken the connection strength between the display panel and the first support frame, thereby achieving the effect of separating the display panel and the first support frame.

[0122] It should be noted that the adhesive line is exposed on at least one side of the supporting frame, including: one end of the adhesive line is exposed on one side of the supporting frame, and may also include: two ends of the adhesive line are exposed on opposite sides of the supporting frame.

[0123] Understandably, when repairing display equipment requires disassembling the display panel and supporting frame, pulling the exposed adhesive lines allows for separation of the display panel and supporting frame, facilitating after-sales repair. Furthermore, by having the adhesive lines exposed on opposite sides of the supporting frame, the display panel and supporting frame can be separated more easily, improving the user experience.

[0124] This disclosure also proposes a method for assembling a display device, which mainly includes the following steps:

[0125] The back panel of the display device is connected to the second connecting frame that supports the outer frame of the display device.

[0126] The diaphragm structure of the display device is assembled between the first support frame and the second support frame of the supporting outer frame, and a gap is formed between the diaphragm structure and the first connecting frame of the supporting outer frame.

[0127] The display panel of the display device is assembled on the side of the first support frame away from the second support frame;

[0128] The gaps provide space for the expansion of the diaphragm structure.

[0129] In this embodiment of the present disclosure, when assembling the backplate, the first backplate portion of the backplate can be assembled between the diaphragm structure and the second support frame, and the second backplate portion of the backplate can be connected to the first backplate portion and the second connecting frame.

[0130] When fixing the second back plate and the second connecting frame, the first fixing hole of the second back plate and the second fixing hole of the second connecting frame can be aligned first, and the second fixing hole can be assembled outside the protruding edge of the first fixing hole so that the second fixing hole surrounds the protruding edge of the first fixing hole; then the second back plate and the second connecting frame can be fixed by passing the fastener through the first fixing hole and the second fixing hole.

[0131] When assembling the adhesive line, the adhesive line can be first set along the connection edge between the display panel and the first support frame, and the adhesive line can be exposed on at least one side of the support frame.

[0132] When assembling the buffer, the buffer can be assembled between the diaphragm structure and the first support frame and connected to the first support frame.

[0133] Understandably, during the assembly of the display device, the backplate is connected to the second connecting frame, and the diaphragm structure is assembled between the first and second supporting frames of the supporting outer frame, with a gap between the diaphragm structure and the first connecting frame of the supporting outer frame, which provides space for the expansion of the diaphragm structure.

[0134] In other words, no additional components are provided between the diaphragm structure and the first connecting frame in this embodiment of the present disclosure. That is, the design of the back plate extension arm is eliminated in the gap. In this way, while reducing the BM area to achieve a narrower frame width, the expansion gap of the diaphragm structure can be increased, reducing the possibility of the diaphragm structure expanding and warping.

[0135] Furthermore, the elimination of the backplate extension arm design in the gap in this embodiment may bring the diaphragm structure closer to the first connecting frame. This not only increases the pressing area of ​​the first support frame pressing the diaphragm structure and improves the reliability of the display device, but also reduces the amount of light appearing at the gap when viewing from the display side of the display panel, thus improving the viewing experience.

[0136] In some embodiments, the display panel of the display device is assembled onto the side of the first support frame opposite to the second support frame, including:

[0137] Multiple positioning points are laser-etched on the adhesive surface of the first support frame on the side opposite to the second support frame.

[0138] Acquire dispensing data for multiple positioning points;

[0139] Based on dispensing data, control the dispensing equipment to dispense adhesive onto the dispensing surface of the bonded parts;

[0140] The display panel is assembled onto the adhesive surface, allowing the adhesive to bond the display panel and the first support frame.

[0141] In this embodiment of the present disclosure, multiple positioning points can be laser-etched onto the dispensing surface according to a preset dispensing trajectory using a laser machine in the dispensing equipment.

[0142] It should be noted that when multiple positioning points are set on the dispensing surface, the multiple positioning points can be evenly distributed on the dispensing surface along the preset dispensing trajectory, and the distance between two adjacent positioning points is equal.

[0143] In this embodiment of the disclosure, obtaining dispensing data for multiple positioning points may include: acquiring coordinate data of multiple positioning points on the dispensing surface through the camera component of the dispensing device.

[0144] It should be noted that, as Figure 1 and Figure 4 As shown, the first support frame 102 may deform in the horizontal direction of the dispensing surface 1020, causing the dispensing surface 1020 to become a wavy surface. By analyzing the coordinate data of multiple positioning points on the dispensing surface, the degree of deformation of the dispensing surface can be known. Therefore, based on the coordinate data of multiple positioning points, the dispensing can be controlled, which can reduce the impact of the dispensing surface deformation on the dispensing and improve the dispensing accuracy.

[0145] In this embodiment of the disclosure, obtaining dispensing data for multiple positioning points may further include: collecting distance data between multiple positioning points and the dispensing head of the dispensing device through the ranging component of the dispensing device.

[0146] It should be noted that, as Figure 1 and 4As shown, the first support frame 102 may also have uneven deformation in the direction perpendicular to the dispensing surface 1020. By analyzing the distance data between multiple positioning points and the dispensing head, the degree of deformation of the first support frame in the direction perpendicular to the dispensing surface can be known. Therefore, based on the distance data of multiple positioning points, the dispensing can be controlled, which can reduce the impact of the distance variation between the dispensing head and different positions of the dispensing surface on the dispensing width and improve the dispensing accuracy.

[0147] Understandably, considering that the dispensing condition of the adhesive affects the reliability of fixing the display panel and the first support frame, this disclosure proposes to obtain dispensing data by lasering multiple positioning points on the dispensing surface. This can improve the dispensing accuracy based on the dispensing data, thereby improving the reliability of fixing the display panel and the first support frame.

[0148] In some embodiments, acquiring dispensing data for multiple positioning points includes:

[0149] The camera component of the dispensing equipment collects coordinate data of multiple positioning points;

[0150] Based on dispensing data, the dispensing equipment is controlled to dispense adhesive onto the dispensing surface of the bonded parts, including:

[0151] The coordinate data of multiple positioning points are fitted to obtain the first fitted data;

[0152] When the first fitted data is within the first preset error range, the dispensing head of the dispensing device is controlled to dispense adhesive onto the dispensing surface based on the fitted trajectory formed by the first fitted data.

[0153] In this embodiment, the camera assembly can be disposed on the dispensing head of the dispensing device. After fixing the dispensing device and the supporting frame, the dispensing head can be driven to move along the set direction of the positioning points to collect coordinate data of multiple positioning points.

[0154] It should be noted that during the process of the camera component acquiring multiple positioning points, the dispensing head will not dispense adhesive, that is, the dispensing head is in the off state.

[0155] In this embodiment of the disclosure, a preset fitting algorithm can be used to fit the coordinate data of multiple positioning points to obtain the first fitted data. This preset fitting algorithm includes linear regression, spline interpolation, etc., and this embodiment of the disclosure does not impose any limitations.

[0156] The first fitting data mentioned above is within the first preset error range, indicating that the deformation of the dispensing surface of the first support frame has not exceeded the standard. Therefore, based on the fitting trajectory formed by the first fitting data, the dispensing head of the dispensing device can be controlled to dispense adhesive onto the dispensing surface.

[0157] If the first fitted data is outside the first preset error range, it indicates that the deformation of the adhesive surface of the current first support frame exceeds the standard, and the current support frame needs to be replaced. Then, it is necessary to judge whether the deformation of the adhesive surface of the replaced support frame exceeds the standard.

[0158] It should be noted that judging whether the deformation of the adhesive surface exceeds the standard based on the first fitted data can eliminate the support frame that exceeds the standard in advance.

[0159] It is understandable that, when the first fitted data is within a first preset error range, the dispensing head of the dispensing device, based on the fitted trajectory formed by the first fitted data, can be controlled to dispense adhesive onto the dispensing surface, thus achieving precise dispensing onto the dispensing surface. For example, as... Figure 5 As shown, the distance S2 from the adhesive part to the edge of the adhesive part can be precisely controlled, thereby enabling the adhesive part to better fix the display panel and the first support frame.

[0160] In some embodiments, the fitted trajectory includes at least one corner position; based on the fitted trajectory formed by the first fitted data, controlling the dispensing head of the dispensing device to dispense adhesive onto the dispensing surface includes:

[0161] When the dispensing head is controlled to dispense adhesive along the fitted trajectory, if the dispensing head is detected to have moved to a corner position, the movement speed of the dispensing head is reduced to the first set speed, and the amount of adhesive supplied by the dispensing head is reduced, so that the adhesive is dispensed on the dispensing surface.

[0162] If it is detected that the dispensing head has changed from the first direction of movement to the second direction of movement at the corner position, the movement speed of the dispensing head is increased to the second set speed, and the amount of glue supplied by the dispensing head is increased, so that the adhesive is applied to the dispensing surface.

[0163] In this embodiment of the disclosure, the fitted trajectory includes corner positions. For example... Figure 4 As shown, glue pooling can occur during the dispensing process at corners, which can easily lead to glue overflow at the corners during the pressing of the first support frame and the display panel. Therefore, this embodiment proposes to first identify whether the dispensing head has moved to a corner position, and then adjust the movement speed of the dispensing head and the glue supply at the corner position. This can reduce glue pooling at the corner position, thereby reducing glue overflow during assembly.

[0164] It should be noted that the camera component installed on the dispensing head can be used to identify whether the dispensing head has moved to a corner position, and whether the dispensing head adjusts its movement direction when it moves to a corner position.

[0165] In this embodiment of the present disclosure, when the dispensing head moves to the corner position, the movement speed of the dispensing head and the amount of adhesive supplied are reduced, which can reduce the occurrence of adhesive accumulation at the corner position.

[0166] It should be noted that the first set speed can be set to a value lower than the preset speed, depending on the actual situation. For example, the first set speed can be set to 0.

[0167] In this embodiment, the dispensing head changes its direction of movement at the corner. When the dispensing head is adjusted to the second direction of movement, the movement speed of the dispensing head and the amount of glue supplied are increased. This is compatible with the reduction of the movement speed of the dispensing head and the amount of glue supplied when the dispensing head moves to the corner, thereby minimizing the occurrence of glue accumulation at the corner.

[0168] It should be noted that the second set speed can be set to a value greater than the preset speed value according to the actual situation, and this embodiment does not limit this.

[0169] The first direction of motion and the second direction of motion are at an angle, which can be an acute angle, an obtuse angle or a right angle, etc., and the embodiments disclosed herein do not limit this.

[0170] In this embodiment of the disclosure, during the dispensing process, the movement speed of the dispensing head is positively correlated with the amount of adhesive supplied. A higher movement speed results in a greater amount of adhesive supplied, while a lower movement speed results in a smaller amount of adhesive supplied. This allows for more uniform dispensing.

[0171] In this embodiment of the disclosure, the fitted trajectory further includes a starting position and an ending position, and the corner position is located between the starting position and the ending position. The movement of the dispensing head along the fitted trajectory includes at least: the dispensing head moving from the initial position to the corner position, and the dispensing head moving from the corner position to the ending position. When there are at least two corner positions, the movement of the dispensing head along the fitted trajectory further includes: the dispensing head moving from an adjacent first corner position to an adjacent second corner position.

[0172] Here, the embodiments of this disclosure can be based on the movement principle that the dispensing head reduces its movement speed to a first set speed when it moves to a corner position, and increases its movement speed to a second set speed when it is adjusted from the first movement direction to the second movement direction at the corner position. This allows for the control of the dispensing head to move from the initial position to the corner position, the control of the dispensing head to move from the corner position to the end position, and the control of the dispensing head to move from the first corner position to the second corner position.

[0173] It should be noted that the movement of the control point adhesive head from its initial position to the corner position may include:

[0174] One scenario involves controlling the dispensing head to move at a constant speed towards the corner position at a third set speed, and then reducing the speed to the first set speed when it reaches the corner position.

[0175] Another scenario involves controlling the dispensing head to first increase its movement speed to the third set speed, then moving at a constant speed at the third set speed, and finally reducing it to the first set speed when it reaches a corner.

[0176] The movement of the control point nozzle from the corner position to the end position may include:

[0177] One approach is to increase the speed of the dispensing head to a second set speed, and then have the dispensing head move at the second set speed at a constant speed to the endpoint.

[0178] Another approach is to first increase the speed of the dispensing head to the second set speed, then move the dispensing head at a constant speed at the second set speed, and finally reduce the speed of the dispensing head to the fourth set speed when it reaches the end position.

[0179] The movement of the control point adhesive head from the first corner position to the second corner position may include:

[0180] One approach is to first increase the speed of the dispensing head to the second set speed, then move the dispensing head at a constant speed at the second set speed, and finally reduce the speed of the dispensing head to the first set speed when the dispensing head reaches the second corner position.

[0181] Another approach is to first increase the dispensing head's movement speed to the second set speed, then control the dispensing head to decrease its movement speed starting from the second set speed, and finally reduce the dispensing head's movement speed to the first set speed when it reaches the second corner position.

[0182] For example, such as Figure 4 As shown, the fitted trajectory includes: the first adhesive trajectory from the starting position L1 to the first corner position L2, the second adhesive trajectory from the first corner position L2 to the second corner position L3, and the third adhesive trajectory from the second corner position L3 to the ending position L4.

[0183] During the movement of the dispensing head along the first dispensing trajectory, the dispensing head is controlled to move towards the first corner position L2 at a set speed V1, and when the dispensing head moves to the first corner position L2, the movement speed of the dispensing head is reduced to the first set speed.

[0184] During the movement of the dispensing head along the second dispensing trajectory, the dispensing head is controlled to move towards the second corner position L3 at a set speed V2, and when the dispensing head moves to the second corner position L3, the movement speed of the dispensing head is reduced to the first set speed.

[0185] During the movement of the dispensing head along the third dispensing trajectory, the dispensing head is first controlled to move towards the endpoint position L4 at a set speed V3, and the dispensing head movement speed is reduced when it reaches the endpoint position L4.

[0186] It should be noted that V1, V2, and V3 are vector velocities. The direction of velocity of V1 is the same as the extension direction of the first adhesive dot trajectory, the direction of velocity of V2 is the same as the extension direction of the second adhesive dot trajectory, and the direction of velocity of V3 is the same as the extension direction of the third adhesive dot trajectory. V1, V2, and V3 can also be vector velocities with equal values ​​but opposite directions.

[0187] Here, as the dispensing head moves along the first and second dispensing trajectories, the direction of movement of the dispensing head changes by 90 degrees. The speed of the dispensing head can be adjusted from V1→0→V2. The amount of glue supplied is gradually reduced first and then gradually increased after the 90-degree movement direction is adjusted.

[0188] During the movement of the dispensing head along the second and third dispensing trajectories, the direction of movement of the dispensing head changes by 90 degrees. The speed of the dispensing head can be adjusted from V2→0→V3→0. The amount of glue supplied gradually decreases and then gradually increases and then gradually decreases after adjusting the 90-degree movement direction.

[0189] In some embodiments, acquiring dispensing data for multiple positioning points includes:

[0190] The distance data between multiple positioning points and the dispensing head of the dispensing equipment is collected by the ranging component of the dispensing equipment.

[0191] Based on dispensing data, the dispensing equipment is controlled to dispense adhesive onto the dispensing surface of the bonded parts, including:

[0192] The distance data corresponding to multiple positioning points are fitted to obtain the second fitted data;

[0193] When the distance difference between the highest and lowest points of the fitting curve formed by the second fitting data is within a second preset error range, the dispensing head is controlled to dispense adhesive onto the dispensing surface based on the second fitting data.

[0194] In this embodiment of the disclosure, the ranging component can be disposed on the dispensing head of the dispensing device. After fixing the dispensing device and the supporting frame, the dispensing head can be driven to move along the set direction of the positioning points to collect distance data corresponding to multiple positioning points.

[0195] It should be noted that during the process of the ranging component collecting multiple positioning points, the dispensing head will not dispense adhesive, that is, the dispensing head is in the off state.

[0196] In this embodiment of the disclosure, a preset fitting algorithm can be used to fit the distance data corresponding to multiple positioning points to obtain second fitted data. This preset fitting algorithm includes linear regression, spline interpolation, etc., and this embodiment of the disclosure does not impose any limitations.

[0197] The aforementioned distance difference is within the second preset error range, indicating that the deformation of the first support frame in the direction perpendicular to the dispensing surface has not exceeded the standard. Therefore, based on the second fitting data, the dispensing head of the dispensing device can be controlled to dispense adhesive onto the dispensing surface.

[0198] If the aforementioned distance difference is outside the second preset error range, it indicates that the deformation of the current first support frame in the direction perpendicular to the adhesive surface exceeds the standard, and the current support frame needs to be replaced. Then, it is necessary to re-evaluate whether the deformation of the first support frame in the direction perpendicular to the adhesive surface of the replaced support frame exceeds the standard.

[0199] Understandably, when the distance difference is within the second preset error range, based on the second fitted data, the dispensing head of the dispensing device is controlled to dispense adhesive onto the dispensing surface, thereby achieving precise adhesive application to the dispensing surface.

[0200] In some embodiments, based on second fitted data, controlling the dispensing head to dispense adhesive onto the dispensing surface includes:

[0201] Based on the second fitted data, the actual distance from the dispensing head to different positions on the dispensing surface is determined;

[0202] If the actual distance differs from the preset desired distance, adjust the position of the dispensing head.

[0203] The adhesive is applied to the adhesive surface using the adjusted dispensing head.

[0204] In this embodiment, the first support frame deforms in the direction perpendicular to the dispensing surface, causing variations in the distance from the dispensing head to different positions on the dispensing surface. This results in inconsistent dispensing width, potentially jeopardizing the reliability of the display panel's fixation. Therefore, this embodiment proposes adjusting the position of the dispensing head based on the actual distance, ensuring a consistent distance from the dispensing head to different positions on the dispensing surface. This leads to more uniform dispensing and improves the reliability of the display panel's fixation.

[0205] It should be noted that during the process of controlling the dispensing head to dispense glue along the fitted trajectory, the actual distance from the dispensing head to each dispensing position in the dispensing trajectory can be determined based on the second fitted data.

[0206] In this embodiment of the disclosure, when the actual distance differs from the preset expected distance, adjusting the position of the dispensing head may include: adjusting the position of the dispensing head based on the difference between the actual distance and the preset expected distance.

[0207] It should be noted that when the actual distance is greater than the preset expected distance, the dispensing head is moved by the absolute value of the difference distance along the vertical direction of the dispensing surface towards a position closer to the dispensing surface. When the actual distance is less than the preset expected distance, the dispensing head is moved by the absolute value of the difference distance along the vertical direction of the dispensing surface away from the dispensing surface.

[0208] Here, when the actual distance and the preset desired distance are equal, dispensing is performed directly based on the current position of the dispensing head, without the need to adjust the position of the dispensing head.

[0209] It is understood that the first support frame may deform in the horizontal direction of the dispensing surface (e.g., in the X and Y directions of the dispensing surface) and also in the vertical direction of the dispensing surface (e.g., in the Z direction of the dispensing surface). Therefore, embodiments of this disclosure propose that the dispensing head can be controlled to dispense the adhesive onto the dispensing surface based on both first and second fitted data. This maximizes dispensing accuracy.

[0210] To better understand the above one or more assembly methods, the following are examples of embodiments of this disclosure:

[0211] like Figure 6 As shown, during the assembly of the display panel onto the first support frame, the dispensing process, addressing deformation occurring in the horizontal direction of the dispensing surface, may include the following steps:

[0212] S1001. Laser-etch multiple positioning points onto the adhesive surface of the first support frame within the current support outer frame.

[0213] S1002. Collect coordinate data of multiple positioning points through the camera component of the dispensing equipment;

[0214] Here, in step S1002, the dispensing head of the dispensing device does not dispense adhesive and is in the dispensing off state. The coordinate data of each positioning point is collected by driving the dispensing head to move.

[0215] S1003. Fit the coordinate data of multiple positioning points to obtain the first fitted data;

[0216] S1004. Determine whether the first fitted data is within the first preset error range; if not, proceed to step S1005; if yes, proceed to steps S1006 and S1007.

[0217] S1005, Replace the current support frame;

[0218] Here, after replacing the current support frame, we will return to step S1001.

[0219] S1006. When the dispensing head is controlled to dispense adhesive along the fitting trajectory corresponding to the first fitting data, if it is detected that the dispensing head has moved to the corner position of the fitting trajectory, the movement speed of the dispensing head is reduced to the first set speed, and the amount of adhesive supplied by the dispensing head is reduced, so that the adhesive is dispensed on the dispensing surface.

[0220] Here, this embodiment of the disclosure detects the corner positions of the fitted trajectory. If the movement reaches a corner position, this embodiment of the disclosure proposes to reduce the movement speed of the dispensing head and reduce the glue supply.

[0221] S1007. When controlling the dispensing head to dispense adhesive along the fitted trajectory, if it is detected that the dispensing head is adjusted from the first direction of movement to the second direction of movement at the corner position, the movement speed of the dispensing head is increased to the second set speed, and the amount of adhesive supplied by the dispensing head is increased, so that the adhesive is dispensed on the dispensing surface.

[0222] Here, if the corner position is adjusted to the second direction of movement, this embodiment of the disclosure proposes to increase the movement speed of the dispensing head in the second direction of movement and increase the amount of adhesive supplied.

[0223] like Figure 7 As shown, during the assembly of the display panel onto the first support frame, the dispensing process, addressing deformation occurring in the vertical direction of the dispensing surface, may include the following steps:

[0224] S2001. Laser-etch multiple positioning points on the adhesive surface of the first support frame within the current support outer frame.

[0225] S2002. Collect distance data between multiple positioning points and the dispensing head of the dispensing equipment through the ranging component of the dispensing equipment;

[0226] S2003. Fit the distance data corresponding to multiple positioning points to obtain the second fitted data;

[0227] S2004. Determine the distance difference between the highest and lowest points of the fitted curve formed by the second fitted data;

[0228] S2005. Determine if the distance difference is within the second preset error range; if not, proceed to step S2006; if yes, proceed to step S2007.

[0229] S2006. Replace the current support frame;

[0230] S2007. Based on the second fitted data, determine the actual distance from the dispensing head to different positions on the dispensing surface;

[0231] S2008. When the actual distance differs from the preset expected distance, the position of the dispensing head is adjusted, and the adhesive is dispensed onto the dispensing surface based on the adjusted dispensing head.

[0232] Here, the difference between the actual distance and the preset expected distance indicates that the dispensing surface of the first support frame is deformed in the vertical direction of the dispensing surface. Therefore, it is necessary to compensate the dispensing head in the vertical direction of the dispensing surface based on the actual distance measured by the ranging component in order to adjust the position of the dispensing head.
