Description

Technical Field

[0001] This utility model relates to the field of display device assembly, and in particular to a substrate fixing device. Background Technology

[0002] During the packaging process of Micro OLED display modules, the Micro OLED screen is prone to generating local heat when it is working. If the heat cannot be dissipated in time, it will directly affect the display stability and lifespan of the screen. Therefore, it is necessary to optimize the heat dissipation performance by attaching flexible heat dissipation copper foil.

[0003] Currently, the industry generally uses manual methods for copper foil lamination. Specifically, operators need to manually fix the Micro OLED screen, then grasp, fold, and press the flexible heat dissipation copper foil to adhere it. Due to the small size of the Micro OLED screen and the thinness of the copper foil, the manual fixing process must be carried out slowly to avoid errors, resulting in extremely low lamination efficiency, which is difficult to meet the needs of large-scale mass production. Furthermore, due to inconsistent manual fixing experience, the pressure applied to the substrate is inconsistent, which can easily cause the screen to shift, resulting in insufficient alignment accuracy between the copper foil and the screen. This, in turn, can easily lead to appearance defects such as bubbles and wrinkles when the copper foil is adhered to the screen surface. Utility Model Content

[0004] This utility model provides a substrate fixing device, which aims to solve the problems of low efficiency and poor bonding quality caused by the reliance on manual fixing of the screen in existing copper foil bonding operations.

[0023] Please see Figures 1-8 This utility model embodiment provides a base fixing device 50. Wherein, Figure 1This is a schematic diagram illustrating the application scenario of the substrate fixing device 50 in this embodiment. The substrate fixing device 50 is used to adjust and fix the position of the substrate 40 so that the flexible sheet 30 can be bonded to the substrate 40 by the flexible sheet automated bonding device 10. In this embodiment, the substrate 40 is a Micro OLED screen, and the flexible sheet 30 is a heat dissipation copper foil. It can be understood that in other embodiments, the substrate 40 may be a motherboard, a watch screen, a backlight module frame, a central control screen, etc., and the flexible sheet 30 may be a metal foil strip, a metal sheet, a ceramic substrate, an adhesive film, etc. During the assembly of the display device, the flexible sheet 30 is first adhered to the back of the substrate 40, with a portion of the flexible sheet 30 extending outside the substrate 40. Then, the substrate 40 is placed face down on the upper substrate fixing device 50. Next, the flexible sheet automatic bonding device 10 folds the flexible sheet 30 extending outside the substrate 40 from the side of the substrate 40 to the front of the substrate 40, and rolls it to the side and / or front of the substrate 40.

[0024] Specifically, the substrate fixing device 50 of this embodiment includes a support platform 5 for supporting the substrate 40; the support platform 5 includes: a base 51, a support seat 52, a fixing component 53, and a correction component 54; the support seat 52 is movably connected to the base 51 and is used to place the substrate 40; the support seat 52 is connected to the correction component 54, and the correction component 54 is fixedly connected to the base 51 and is used to move the support seat 52 to adjust the position of the substrate 40; the fixing component 53 includes a pressure block 531 and a fixing drive member 532, the pressure block 531 is disposed above the support seat 52, and the fixing drive member 532 is used to drive the pressure block 531 to move closer to or away from the support seat 52 to press against the substrate 40 on the support seat 52 or to release the substrate 40.

[0025] In practice, after the substrate 40 is placed on the support seat 52, the fixed drive component 532 is activated to move the pressure block 531 onto the substrate 40 so as to press the substrate 40 down from above and make the substrate 40 firmly abut against the support seat 52; then, the correction component 54 is activated so that the support seat 52 and the substrate 40 on the support seat 52 are adjusted to the preset fitting position.

[0026] In this embodiment, the substrate fixing device 50 drives the pressure block 531 close to the support seat 52 via the fixing drive component 532 to press against the substrate 40, thereby automatically fixing the substrate 40 and ensuring consistent pressure applied to the substrate 40. At the same time, by setting the correction component 54 to adjust the position of the substrate 40, the precise correction of the position of the substrate 40 is achieved, significantly improving the alignment accuracy between the flexible sheet 30 and the substrate 40. In addition, the mechanized fixing and correction operation significantly improves the overall work efficiency compared to manual fixing, meeting the needs of mass production. Moreover, the substrate 40 does not shift and is precisely aligned, fundamentally reducing the generation of undesirable appearances such as bubbles and wrinkles during bonding, and ensuring bonding quality.

[0027] See Figure 5 As shown, the substrate fixing device 50 also includes an adsorption component 55; the adsorption component 55 is connected to the top of the support base 52 and is used to adsorb the substrate 40. After the substrate 40 is placed on the adsorption component 55, the adsorption component 55 forms a negative pressure through a negative pressure system, using atmospheric pressure to adsorb the substrate 40 onto the upper surface of the adsorption component 55; before the pressure block 531 presses against the substrate 40, the adsorption component 55 can pre-fix the substrate 40 to prevent the substrate 40 from shifting; during the pressing of the pressure block 531 and the adjustment of the correction component 54, the adsorption component 55 continues to adsorb, working together with the pressure block 531 to fix the substrate 40; after the bonding is completed, the adsorption component 55 releases the negative pressure, and the substrate 40 can be removed. The adsorption component 55 and the pressure block 531 work together to enhance the fixing stability, prevent the substrate 40 from sliding during position correction, and improve the correction accuracy; moreover, the adsorption method does not cause mechanical damage and can protect the surface of fragile substrates 40 such as Micro OLED screens.

[0028] In a further embodiment, the adsorption component 55 includes: a suction plate 551 and a suction nozzle 552; the suction plate 551 is provided with a plurality of suction holes 5511 arranged in an array, and the suction plate 551 and the suction nozzle 552 are fixedly connected to the top of the support base 52; the suction plate 551 and the suction nozzle 552 respectively adsorb both ends of the substrate 40. In specific implementation, the main body of the substrate 40 can be adsorbed by the suction plate 551, and the extension of the substrate 40 can be adsorbed by the suction nozzle 552. In specific implementation, a negative pressure system can be used to connect the suction holes 5511 of the suction plate 551 and the suction nozzle 552 through pipelines to form a negative pressure, thereby achieving adsorption and fixation of the substrate 40. The array of suction holes 5511 on the suction plate 551 ensures uniform distribution of adsorption force, preventing deformation of the main body of the substrate 40; the suction nozzle 552 accurately adsorbs the extension, ensuring the bonding accuracy of the flexible sheet 30 near the extension, and further reducing poor bonding effects such as bubbles and wrinkles.

[0029] See Figure 6As shown, the fixing component 53 also includes: a rotating rod 533 and a rotating shaft 534; the rotating rod 533 and the rotating shaft 534 are arranged perpendicularly to each other, one end of the rotating rod 533 is fixedly connected to the pressure block 531, and the other end is fixedly connected to the rotating shaft 534; the rotating shaft 534 is drivenly connected to the output end of the fixed drive component 532, which is used to drive the rotating shaft 534 to rotate. After the fixed drive component 532 is started, it outputs rotational power, causing the rotating shaft 534 to rotate around its own axis; because the rotating rod 533 is perpendicular to and fixedly connected to the rotating shaft 534, the rotating shaft 534 will synchronously drive the rotating rod 533 to rotate around the axis of the rotating shaft 534; the end of the rotating rod 533 away from the rotating shaft 534 is fixed to the pressure block 531, thereby causing the pressure block 531 to rotate synchronously with the rotating rod 533, realizing the movement of the pressure block 531 towards or away from the bearing seat 52, and completing the pressing or releasing of the base 40. The arrangement of the rotating shaft 534 and the rotating rod 533 allows the pressure block 531 to extend from the outside of the support seat 52 to above the support seat 52, providing a stable and reliable force transmission for the pressure block 531. This allows the pressure block 531 to press against the base 40 from above, preventing the base 40 from shifting due to tension or mechanical vibration during the clamping, folding, and rolling stages of the flexible sheet 30, thus ensuring the accuracy and stability of the base 40's position.

[0030] In this embodiment, the fixed drive component 532 is a rotary cylinder. The rotary cylinder precisely controls the movement of the pressure block 531 through rotational motion, achieving rapid and stable clamping of the substrate 40, effectively preventing displacement of the substrate 40 during the bonding process, and ensuring consistent pressure application. It is understood that in other embodiments, a servo motor, linear motor, stepper motor, hydraulic cylinder, piezoelectric actuator, or other drive components can be used instead of the rotary cylinder.

[0031] In a further embodiment, the fixing component 53 further includes: a fixing seat 535; the fixing seat 535 is fixedly connected to the support seat 52, and the fixing drive member 532 is fixedly connected to the fixing seat 535. The fixing seat 535 is fixed to the support seat 52, and when the correction component 54 drives the support seat 52 to move or rotate, the fixing seat 535 will move synchronously with the support seat 52; it can also be understood that the fixing drive member 532 is fixed on the fixing seat 535, and therefore will move synchronously with the fixing seat 535 and the support seat 52. The fixing seat 535 provides a stable installation reference for the fixing drive member 532, avoiding the problem of unstable installation caused by the structural limitations of the support seat 52 when the fixing drive member 532 is directly installed on the support seat 52; at the same time, the synchronous movement of the fixing drive member 532 with the support seat 52 can prevent the pressure block 531 from shifting relative to the base 40 when the support seat 52 is adjusted, ensuring the continuous and stable pressing of the pressure block 531 on the base 40, and preventing the base 40 from loosening during the adjustment process.

[0032] See Figures 7-8As shown, the correction component 54 includes an angle correction component 541, which drives the support 52 to rotate to adjust the angle of the base 40. When the control system or vision inspection system of the equipment detects a deviation in the angle of the base 40, it sends a control signal to the angle correction component 541 to control the angle correction component 541 to drive the support 52 to rotate by a specified angle. After receiving the control signal, the angle correction component 541 starts and outputs a rotational driving force. This driving force is transmitted to the support 52, causing the support 52 to rotate around a preset axis perpendicular to the platform of the support 52. The base 40 placed on the support 52 rotates synchronously with the support 52 until the angle of the base 40 reaches the specified angle. Then, the angle correction component 541 stops driving, completing the angle adjustment of the base 40. The angle correction component 541 can accurately correct the angle deviation when the substrate 40 is fed, solving the problems of low accuracy and low efficiency of manual angle adjustment; the angle adjustment is achieved through mechanized drive, ensuring the angle consistency of each substrate 40, avoiding poor bonding effects such as misalignment and wrinkles in subsequent flexible sheet 30 bonding due to angle deviation, and reducing the defect rate; at the same time, the angle adjustment is automated, requiring no manual intervention, reducing labor costs and adapting to the needs of large-scale mass production.

[0033] In a further embodiment, the angle correction component 541 includes: a turntable 5411 and a rotation drive 5412; the turntable 5411 is horizontally arranged and rotatably connected to the base 51, the support seat 52 is fixedly connected to the top of the turntable 5411, and the rotation drive 5412 is used to drive the turntable 5411 to rotate. It is understood that the axis of the turntable 5411 is perpendicular to the platform of the turntable 5411 and is vertically arranged. After the rotation drive 5412 is activated, it outputs power, acting on the horizontally arranged turntable 5411; the turntable 5411 is rotatably connected to the base 51, and under the driving force of the rotation drive 5412, the turntable 5411 rotates around its own central axis; the support seat 52 is fixed to the top of the turntable 5411 and rotates synchronously with the turntable 5411. The horizontal arrangement of the turntable 5411 ensures that the support seat 52 and the base 40 remain horizontal during angle adjustment, preventing the base 40 from slipping or shifting position due to tilting.

[0034] In a further embodiment, the angle correction component 541 further includes: a first slider 5413, a second slider 5414, a first slide rail 5415, and a second slide rail 5416; the first slide rail 5415 and the second slide rail 5416 extend horizontally and are arranged perpendicularly to each other, the first slider 5413 and the second slider 5414 are slidably connected to the first slide rail 5415 and the second slide rail 5416, respectively; the first slide rail 5415 is fixedly connected to the base 51, the second slide rail 5416 is fixedly connected to the first slider 5413, and the edge of the turntable 5411 is connected to the second slider 5414; the rotation drive component 5412 is used to drive the first slider 5413 to move linearly along the first slide rail 5415. The rotation drive 5412 drives the first slider 5413 to move linearly along the horizontally extending first slide rail 5415. Since the edge of the turntable 5411 is connected to the second slider 5414, and the second slider 5414 is connected to the first slider 5413 through the second slide rail 5416, when the first slider 5413 moves, the turntable 5411 is subjected to a first horizontal thrust. This thrust is converted into a tangential force on the turntable 5411 at the edge of the turntable 5411, thereby driving the turntable 5411 to rotate around its axis. Under the movement of the first slider 5413 and the turntable 5411, the second slider 5414 adapts to slide along the second slide rail 5416 to ensure that the turntable 5411 rotates smoothly. By using mutually perpendicular slide rails and sliding components, the linear motion of the rotary drive component 5412 is converted into the rotational motion of the turntable 5411. This eliminates the need for a direct rotary drive structure and the need to vertically mount the rotary drive structure on the base 40. This facilitates the mounting of the rotary drive component 5412, the first sliding component 5413, the second sliding component 5414, the first slide rail 5415, and the second slide rail 5416 on one side of the turntable 5411. This results in a compact structure for the bearing platform 5, reduces the overall height of the bearing platform 5, and prevents the base 40 from wobbling due to excessive height, further ensuring the stability of the base 40.

[0035] In this embodiment, the rotation drive 5412 is a drive structure composed of a precision slide table and a stepper motor. It is understood that, in specific implementations, the precision slide table in the rotation drive 5412 can be directly used as the first sliding member 5413, or an additional slider structure can be used as the first sliding member 5413 and fixedly connected to the precision slide table. The drive structure composed of the precision slide table and the stepper motor has high positioning accuracy. The stepper motor can precisely control the movement distance of the slide table by controlling the step angle, thereby ensuring the accuracy of the rotation angle of the turntable 5411 and meeting the high-precision angle correction requirements of the base 40. It is understood that, in other embodiments, a cylinder, hydraulic cylinder, electric cylinder, or other drive component can be used to replace the drive structure composed of the precision slide table and the stepper motor, depending on actual needs.

[0036] In a further embodiment, a steering protrusion 54111 protrudes outward from the sidewall of the turntable 5411, and the steering protrusion 54111 is rotatably connected to the second sliding member 5414. The steering protrusion 54111 provides a stable force transmission connection structure between the second sliding member 5414 and the turntable 5411, avoiding the problems of small contact area and easy wear caused by the second sliding member 5414 directly contacting the sidewall of the turntable 5411; the rotatable connection between the steering protrusion 54111 and the second sliding member 5414 reduces motion interference, so that the linear motion of the second sliding member 5414 can be smoothly converted into the rotational motion of the turntable 5411, improving the stability of angle adjustment; at the same time, the steering protrusion 54111 is set on the sidewall of the turntable 5411, without occupying the space of the bearing seat 52 installed on the top of the turntable 5411, thus optimizing the structural layout of the bearing platform 5.

[0037] In a further embodiment, the angle correction component 541 further includes: a drive shaft 5417, a support seat 5418, and a steering seat 5419; the support seat 5418 is connected to the base 51, the turntable 5411 is rotatably connected to the support seat 5418, the steering seat 5419 is fixedly connected to the support seat 5418, and the first slide rail 5415 is connected to the side wall of the support seat 5418; the steering seat 5419 is provided with a guide groove 54191 on the side near the steering protrusion 54111, and the drive shaft 5417 passes through the guide groove 54191; one end of the drive shaft 5417 is fixedly connected to the steering protrusion 54111, and the other end is rotatably connected to the second sliding member 5414. The first sliding member 5413 moves linearly along the first slide rail 5415 on the side wall of the support base 5418, driving the second slide rail 5416 and the second sliding member 5414 to move synchronously; the second sliding member 5414 drives one end of the transmission shaft 5417 to move synchronously, the transmission shaft 5417 passes through the guide groove 54191 of the steering seat 5419, and moves along the guide groove 54191 under the restriction of the guide groove 54191; the end of the transmission shaft 5417 away from the second sliding member 5414 is fixed to the steering protrusion 54111, thereby driving the steering protrusion 54111 and the turntable 5411 to rotate around the rotation center on the support base 5418; the turntable 5411 drives the bearing seat 52 and the base 40 to rotate synchronously, completing the angle adjustment of the base 40. The support seat 5418 provides stable rotation support for the turntable 5411, preventing the turntable 5411 from shaking and affecting the angle adjustment accuracy; the guide groove 54191 of the steering seat 5419 plays a precise guiding role for the movement of the drive shaft 5417, ensuring that the trajectory of the drive shaft 5417 driving the turntable 5411 to rotate is controllable and reducing angle deviation.

[0038] See Figure 7As shown, the correction assembly 54 includes: a linear correction component 542 connected to the base 51, and an angle correction component 541 connected to the top of the linear correction component 542. The linear correction component 542 drives the angle correction component 541 to move in a first horizontal direction to adjust the horizontal position of the base 40. More specifically, a support base 5418 is connected to the top of the linear correction component 542. After the linear correction component 542 is activated, it outputs a linear driving force, driving the support base 5418 to move in the first horizontal direction. The rotation drive component 5412, the steering seat 5419, the first slide rail 5415, the first sliding member 5413, the second slide rail 5416, the second sliding member 5414, the drive shaft 5417, and the turntable 5411 all move synchronously with the support base 5418 in the first horizontal direction. The angle correction component 541 drives the bearing seat 52 and the base 40 to move synchronously until the base 40 completes the position adjustment in the first horizontal direction. It is also understood that the linear correction component 542 can be used in conjunction with the automated flexible sheet bonding device 10 for bonding operations. For example, in the automated flexible sheet bonding device 10, the roller used to roll the flexible sheet 30 remains stationary relative to its position in the first horizontal direction. The linear correction component 542 drives the substrate 40 to move in the first horizontal direction, so that the roller continuously contacts the substrate 40 during the movement of the substrate 40. The roller achieves continuous rolling of the flexible sheet 30 with the help of the movement of the substrate 40, tightly bonding the flexible sheet 30 to the surface of the substrate 40. The linear correction component 542 achieves precise adjustment of the substrate 40 in the first horizontal direction, and works with the angle correction component 541 to form a dual correction of horizontal position and angle, solving the problem that manual adjustment of position and angle is not possible. The angle correction component 541 moves as a whole with the linear correction component 542, ensuring that the relative position of the angle correction component 541 and the substrate 40 remains unchanged during the adjustment process, avoiding angle deviation caused by horizontal movement, further improving the positioning accuracy of the substrate 40, and ensuring the bonding quality of the flexible sheet 30.

[0039] In this embodiment, the linear correction component 542 is a drive structure consisting of a precision slide table and a stepper motor. The combination of the precision slide table and the stepper motor provides high positioning accuracy and repeatability. The stepper motor can precisely control the slide table's movement distance, meeting the high-precision horizontal correction requirements of the base 40. The precision slide table offers stable transmission and smooth movement, ensuring the base 40 moves smoothly. It is understood that in other embodiments, cylinders, hydraulic cylinders, electric cylinders, or other drive components can be used to replace the drive structure consisting of the precision slide table and the stepper motor, depending on actual needs.

[0040] In a further embodiment, the rotation drive 5412 extends in the same direction as the straightness correction component 542, and the rotation drive 5412 is used to drive the first sliding member 5413 to move along the first horizontal direction. It can be understood that both the rotation drive 5412 and the straightness correction component 542 extend along the first horizontal direction. The rotation drive 5412 drives the first sliding member 5413 to move along the first horizontal direction, thereby rotating the turntable 5411 through the second sliding member 5414 and the drive shaft 5417, achieving angle adjustment of the base 40. The straightness correction component 542 drives the angle correction component 541 to move as a whole along the first horizontal direction, achieving horizontal position adjustment of the base 40. The rotation drive 5412 and the straightness correction component 542 extend in the same direction and act in the same direction, making the structural layout of the support platform 5 more compact and reducing the horizontal space occupied by the support platform 5.

[0041] See Figure 2 As shown, the substrate fixing device 50 also includes: a linear movement mechanism 6; a base 51 is connected to the linear movement mechanism 6, which drives the base 51 to move in the second horizontal direction to adjust the horizontal position of the substrate 40. More specifically, the first horizontal direction and the second horizontal direction are perpendicular to each other. After the linear movement mechanism 6 is activated, it outputs a linear driving force, which acts on the base 51; the base 51 is connected to the linear movement mechanism 6 and moves along the second horizontal direction with the linear movement mechanism 6; the movement of the base 51 causes the entire support platform 5 to move together, thereby adjusting the position of the substrate 40 in the second horizontal direction. The linear movement mechanism 6 can drive the support platform 5 to move to the preset bonding position, that is, below the flexible sheet automated bonding device 10, so that the support platform 5 can quickly complete the preparation before bonding; in addition, the linear movement mechanism 6 cooperates with the linear correction component 542 to form a two-dimensional horizontal position correction, covering the deviation of the substrate 40 in the horizontal direction.

[0042] In this embodiment, the linear movement mechanism 6 is a linear motor module that extends along the second horizontal direction. The linear motor module operates smoothly with minimal vibration, ensuring the stability of the base 40 during movement and preventing displacement. It is understood that in other embodiments, drive modules such as cylinders, hydraulic cylinders, electric cylinders, synchronous belts, and servo motors can be used instead of the linear motor module, depending on actual needs.

[0043] This embodiment provides a substrate fixing device. By using a fixing drive component to drive the pressure block close to the support seat to press against the substrate, the substrate is automatically fixed, which helps to maintain the consistency of pressure applied to the substrate. At the same time, by setting a correction component to adjust the position of the substrate, the precise correction of the substrate position is achieved, which significantly improves the alignment accuracy between the flexible sheet and the substrate. In addition, the mechanized fixing and correction operation significantly improves the overall work efficiency compared with manual fixing, meets the needs of mass production, and the substrate does not shift and the alignment is precise, which fundamentally reduces the generation of undesirable appearances such as bubbles and wrinkles during bonding, and ensures the bonding quality.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
