[0033] As described in the background art, the organic light emitting diode (OLED) display technology is considered as the most potential new display technology of the next generation. Compared with the liquid crystal display technology, the OLED display technology has the advantages of low energy consumption, low cost, self-luminous, wide viewing angle, fast response speed and the like. In the manufacturing process of the curved OLED display module, it is necessary to attach a composite functional adhesive tape to the curved area of the semi-finished module after the cover plate is attached, so as to realize the functions of electromagnetic shielding, heat management or structural reinforcement. However, the existing adhesive tape attaching process has high process complexity and low production efficiency.
[0034] It can be understood that, when the composite functional adhesive tape is attached to the curved area of the semi-finished module through the existing adhesive tape attaching process, the composite functional adhesive tape is first attached to the semi-finished module by a roller, and after the roller attachment is completed, the attached composite functional adhesive tape is further compressed by a pressure head for secondary compression, so as to prevent the adhesive tapes at both ends from being raised. Since the secondary compression is required, the equipment cost and process steps of the adhesive tape attaching process are increased.
[0035] Referring to Figures 1 to 5To solve the above problems, according to one aspect of the present application, the embodiment of the present application provides a tape attaching device, which comprises: a workpiece carrier 10, a tape carrier 20, a roller module 30 and a driving module 40, wherein the workpiece carrier 10 is used for loading a workpiece with a tape attaching surface, the tape attaching surface comprises a flat section and a curved section located at the edge of the flat section; the roller module 30 is rotatably installed on the tape carrier 20; the driving module 40 is drivingly connected with the tape carrier 20 and is used for driving the tape carrier 20 to move back and forth in a first direction and a second direction; the roller module 30 can roll and press the tape on the tape attaching surface by rotating along the rotation axis thereof and moving with the tape carrier 20 in the first direction, and can slide and roll the tape on the tape attaching surface by moving with the tape carrier 20 in the second direction, wherein the rotation axis of the roller module 30 is parallel to the tape attaching surface, the first direction is perpendicular to the rotation axis of the roller module 30, the second direction is parallel to the rotation axis of the roller module 30, and the area of the tape used for attaching to the curved section forms an edge lifting area. The tape attaching device provided by the embodiment can drive the tape carrier 20 to move in the first direction or the second direction by driving the tape carrier 20 through the driving module 40, when the tape carrier 20 is driven to move in the first direction by the driving module 40, the tape carrier 20 can drive the roller module 30 to move in the first direction, and the roller module 30 can rotate to realize the rolling and pressing attachment of the tape, when the tape carrier 20 is driven to move in the second direction by the driving module 40, the tape carrier 20 can drive the roller module 30 to move in the second direction, and the sliding friction between the roller module 30 and the tape can realize the rolling and pressing of the tape, thereby reducing the probability of tape lifting. The tape attaching device provided by the embodiment can realize the attachment and pressing of the tape, simplify the process complexity of tape attachment, and improve the production efficiency. It should be noted that the first direction and the second direction in the embodiment are both parallel to the tape attaching surface, and the second direction is perpendicular to the first direction.
[0036] It should be noted that the workpiece carrier 10 in the embodiment refers to a support platform used for fixing and positioning a workpiece, the surface of which can be provided with vacuum suction holes, clamp structures or positioning pins and the like to ensure that the workpiece maintains a stable posture during tape attaching; the tape carrier 20 refers to a modular platform used for carrying and providing a tape, which is used for conveying the tape to the tape attaching surface of the workpiece in a flat state; the roller module 30 refers to a pressing roller assembly that can rotate around its own axis, which realizes the pressing function by rolling or sliding movement with the tape or the surface of the workpiece.
[0037] It can be understood that the rolling pressing in the embodiment refers to a movement mode of the roller module 30 rotating around its own axis and translating in the first direction at the same time when contacting the adhesive tape, gradually attaching the adhesive tape to the adhesive surface of the workpiece through rolling friction, avoiding bubbles or wrinkles caused by one-time contact, and the sliding rolling refers to a movement mode of the roller module 30 stopping rotating and translating in the second direction, using sliding friction to locally press the adhesive tape to exclude residual bubbles and enhance the interface bonding force.
[0038] In some embodiments, the workpiece in the embodiment is a semi-finished curved display module for completing the cover plate attachment.
[0039] In a specific embodiment, after the adhesive tape is attached to the adhesive surface, the roller module performs sliding rolling on the edge easy warping area of the adhesive tape by translating with the adhesive tape stage in the second direction; by driving the roller module to slide and roll the edge easy warping area of the attached adhesive tape in the second direction parallel to its axis, the internal stress of the adhesive tape attached to the curved section can be effectively reduced or even eliminated, the edge warping risk of the adhesive tape is reduced, and the reliability and durability of the adhesive tape attachment are improved.
[0040] In some embodiments, the sliding rolling in the embodiment is only performed on the edge easy warping area of the adhesive tape, by setting the sliding rolling to only act on the edge easy warping area of the adhesive tape, the compaction effect of the adhesive tape in the curvature mutation area can be targetedly strengthened, the interface bubbles remaining in the edge easy warping area of the adhesive tape due to uneven stretching during initial attachment can be excluded, and the edge warping trend can be effectively inhibited, while avoiding excessive rolling of the flat section to damage the adhesive tape, the conformality and bonding reliability of the attachment of the edge easy warping area of the adhesive tape are improved.
[0041] In a specific embodiment, the adhesive surface in the embodiment includes two curved sections, and the two curved sections are located at the two ends of the flat section in the first direction. Since the two curved sections are located at the two ends of the flat section in the first direction, the roller module 30 can eliminate residual stress and interface bubbles caused by uneven stretching of the adhesive tape by reciprocating sliding rolling on the two end curved sections, inhibit the risk of symmetry warping, and ensure uniform attachment and long-term adhesion stability of the adhesive tape on the adhesive surface.
[0042] In a specific embodiment, when the workpiece is loaded on the workpiece carrier 10 and the adhesive tape is loaded on the adhesive tape carrier 20, the adhesive tape carrier 20 has a first state in which the roller module 30 is pressed against the adhesive surface to perform rolling pressing and / or sliding rolling, and a second state in which the roller module 30 is separated from the adhesive surface. It should be noted that the first state in this embodiment refers to a working state in which the adhesive tape carrier 20 adjusts the spatial position through the driving module 40 to keep the roller module 30 in contact with the adhesive surface of the workpiece and apply a predetermined pressure, in which state the roller module 30 can perform rolling pressing and / or sliding rolling to achieve the attachment and compaction of the adhesive tape; the second state refers to a non-working state in which the adhesive tape carrier 20 adjusts the spatial position through the driving module 40 to completely separate the roller module 30 from the adhesive surface of the workpiece, in which state an operation space can be provided for loading and unloading the workpiece, replacing the adhesive tape, or maintaining the equipment.
[0043] In a specific embodiment, the driving module 40 in this embodiment can also drive the adhesive tape carrier 20 to move in a third direction, wherein the third direction is perpendicular to the first direction and the second direction, respectively. The driving module 40 drives the adhesive tape carrier 20 to move in the third direction to switch the adhesive tape carrier 20 between the first state and the second state. By driving the adhesive tape carrier 20 to move in the third direction through the driving module 40, the adhesive tape carrier 20 can be quickly switched between the first state and the second state. Specifically, by controlling the pressing or separation of the roller module 30 and the adhesive surface through movement in the third direction, the pressure during rolling pressing and sliding rolling can be well controlled and stable, improving the attachment quality of the adhesive tape. At the same time, the quick switching between the first state and the second state can facilitate the rapid loading and unloading of the workpiece, improving the production efficiency of the adhesive tape attachment.

By setting the device main body 50 as the overall support structure, the workpiece carrier 10 and the driving module 40 can be effectively supported, improving the process stability of the adhesive tape attachment device. By installing the adhesive tape carrier 20 on the output end of the driving module 40 and locating it on the side of the workpiece carrier 10 away from the device main body 50, efficient power transmission between the driving module 40 and the adhesive tape carrier 20 can be ensured, and at the same time, the structure of the adhesive tape attachment device can be made more compact to some extent, reducing the occupied space of the adhesive tape attachment device.
[0045] It should be noted that the device body 50 in the embodiment refers to the base support structure of the adhesive tape attaching device, which is usually a rigid frame or platform, used to fix and carry other functional components, and to ensure the mechanical stability and vibration resistance of the adhesive tape attaching device.
[0046] Referring to Figures 1 to 3 As shown, in a specific embodiment, the workpiece carrier 10 in the embodiment is provided with a first adsorption assembly, and the workpiece carrier 10 is loaded with the workpiece through the first adsorption assembly. By providing the first adsorption assembly on the workpiece carrier 10, the workpiece carrier 10 can be adsorbed and fixed through the negative pressure generated by the first adsorption assembly, avoiding the damage or positioning deviation of the workpiece surface caused by the traditional mechanical clamping method. The adsorbed and fixed loading method can effectively inhibit the slight displacement or vibration of the workpiece, and provide a high-precision and high-stability positioning reference for the adhesive tape attaching process. It should be noted that the first adsorption assembly in the embodiment refers to a negative pressure adsorption mechanism integrated on the surface of the workpiece carrier 10, which generates and maintains a negative pressure environment to generate an adsorption force on the surface of the workpiece in a non-contact manner, realizing the fixation and positioning of the workpiece.
[0047] In some embodiments, the workpiece carrier 10 in the embodiment is provided with a first vacuum adsorption area, and a plurality of first vacuum adsorption holes are arranged on the first vacuum adsorption area in the embodiment. The first adsorption assembly in the embodiment includes a first vacuum generating assembly, which is in communication with each first vacuum adsorption hole for generating adsorption negative pressure on the first vacuum adsorption area through the first vacuum adsorption hole. By arranging a plurality of first vacuum adsorption holes on the first vacuum adsorption area and making each first vacuum adsorption hole communicate with the first vacuum generating assembly, the adhesive tape attaching device can generate uniform adsorption negative pressure on the first vacuum adsorption area through the first vacuum generating assembly and the first vacuum adsorption hole, thereby reliably fixing the workpiece on the workpiece carrier 10, preventing the workpiece from shifting or vibrating during the rolling and pressing process of the roller module 30, and ensuring the stability of the adhesive tape attaching process and the accuracy of the attaching position.
[0048] Referring to Figures 1 to 3As shown, in a specific embodiment, the adhesive tape loading platform 20 in the embodiment is provided with a second adsorption assembly, and the adhesive tape is loaded by the second adsorption assembly. By providing the second adsorption assembly on the adhesive tape loading platform 20, the adhesive tape loading platform 20 can be adsorbed and fixed by the negative pressure generated by the second adsorption assembly, avoiding the deformation, pollution or displacement of the adhesive tape caused by the traditional mechanical grabbing or pre-adhesive method. In addition, the adsorption and fixed loading method can ensure that the adhesive tape remains flat and stretched before being attached, reducing the risk of wrinkles and bubbles in the initial attachment stage, and providing a stable tension basis for the rolling and pressing of the roller module 30. It should be noted that the second adsorption assembly in the embodiment refers to a negative pressure adsorption mechanism integrated on the surface of the adhesive tape loading platform 20, which generates and maintains a negative pressure environment to generate an adsorption force on the surface of the adhesive tape in a non-contact manner, achieving the fixation and positioning of the adhesive tape.

The second adsorption assembly in the embodiment includes a second vacuum generating assembly, which is in communication with each second vacuum adsorption hole for generating adsorption negative pressure on the second vacuum adsorption area through the second vacuum adsorption hole. By arranging a plurality of second vacuum adsorption holes on the second vacuum adsorption area and making each second vacuum adsorption hole in communication with the second vacuum generating assembly, the adhesive tape attaching device can provide uniform and reliable adsorption force to the adhesive tape before and during the attaching operation, avoiding the offset, wrinkles or loosening of the adhesive tape, and ensuring the accuracy of the initial attachment position.

The execution end of the multi-axis robot is fixedly connected with the adhesive tape loading platform 20. The multi-axis robot in the embodiment is configured to drive the adhesive tape loading platform 20 to realize high-precision reciprocating movement and positioning in the first direction, the second direction and the third direction. Through the multi-degree-of-freedom motion characteristics of the multi-axis robot, the roller module 30 can be flexibly and accurately controlled to complete complex motion trajectories, such as rolling and pressing of the adhesive tape and sliding and pressing of the attached adhesive tape. By setting the driving module 40 as a multi-axis robot, the positioning accuracy and action consistency of the rolling and pressing and sliding and pressing process can be significantly improved, the adaptability and processing capacity of the adhesive tape attaching device to workpieces with complex curved surface profiles can be enhanced, and the automation level, production efficiency and yield of the adhesive tape attaching device can be greatly improved.
[0051] Referring to Figures 1 to 5In some embodiments, the tape adhering device in the present embodiment comprises a first linear drive assembly, a second linear drive assembly and a third linear drive assembly. The first linear drive assembly is mounted on the device main body 50, and the movement direction of the output end of the first linear drive assembly is parallel to the first direction, for driving the tape carrier 20 to move back and forth along the first direction.

It can be understood that in some embodiments, the first linear drive assembly, the second linear drive assembly and the third linear drive assembly in the present embodiment are air cylinders, and of course in other embodiments, the first linear drive assembly, the second linear drive assembly and the third linear drive assembly in the present embodiment can also be hydraulic cylinders, linear motors or other linear drive devices.
[0052] In some embodiments, the tape carrier 20 in the present embodiment is provided with a first support shaft, and the roller module 30 comprises a first roller main body provided with a first mounting hole, and the first roller main body is rotatably sleeved on the first support shaft through the first mounting hole. By rotatably sleeving the first roller main body on the first support shaft of the tape carrier 20, a rotating pair with compact structure, good rigidity and stable operation can be formed, ensuring that the roller module 30 can rotate smoothly around the fixed axis during rolling and pressing, and improving the uniformity and reliability of tape adhering.

By arranging the first rotary bearing between the first mounting hole and the first support shaft, the frictional resistance and movement noise during rotation of the first roller main body can be significantly reduced, ensuring the stability and smoothness of the rolling and pressing process, and improving the mechanical life and long-term operation reliability of the roller module 30.

The tape stage 20 is provided with a second support shaft, and the roller module 30 comprises a second roller body provided with a second mounting hole, and the second roller body is rotatably sleeved on the second support shaft through the second mounting hole. The floating connection module composed of the sliding connection block and the elastic reset member enables the roller module 30 to float along the third direction and adaptively fit the taping surface of the workpiece. Moreover, the rotation cooperation between the second roller body and the second support shaft can flexibly compensate the unevenness of the taping surface or the installation error while maintaining the precise rolling and pressing function, thereby ensuring uniform pressure on the tape and avoiding poor pressing or damage to the workpiece caused by rigid contact.
[0055] In some embodiments, the tape attaching device further comprises a second rotation bearing, which is located in the second mounting hole and cooperates with the inner side wall of the second mounting hole, and the inner ring of the second rotation bearing cooperates with the outer ring of the second support shaft. The second rotation bearing arranged between the second mounting hole and the second support shaft can significantly reduce the friction resistance and movement noise when the second roller body rotates, thereby ensuring the stability and smoothness of the rolling and pressing process, and improving the mechanical life and long-term operation reliability of the roller module 30.

The integration of the feeding module on the tape stage 20 can form a compact structural layout of the feeding source and the attaching execution unit, shorten the transmission path of the tape from the feeding to the attaching, and ensure the constant tension of the tape during conveying by arranging the tension controller on the downstream tape conveying path of the feeding disc, thereby effectively improving the stability and positioning accuracy of the tape conveying.

The driving feeding roller is connected with the output shaft of the feeding driving motor. The driven pressing roller is arranged opposite to the driving feeding roller through the elastic pressing mechanism, and a tape conveying channel is formed between the driving feeding roller and the driven pressing roller. It should be noted that the elastic pressing mechanism in the present embodiment can provide continuous and stable pressing force for the driven pressing roller, so as to ensure that the driving feeding roller reliably clamps the tape and prevent the tape from slipping or deviating during the conveying process. The feeding driving motor can directly control the rotation angle of the driving feeding roller, so that the tape can be conveyed to the second vacuum adsorption area in a fixed length.
[0058] In some embodiments, the tape attaching device in the present embodiment further comprises a cutting module for cutting the tape positioned and adsorbed on the second vacuum adsorption area. The cutting module in the present embodiment comprises a fourth linear driving assembly and a cutting tool assembly. The fourth linear driving assembly is installed on the tape loading platform 20.

It can be understood that in some embodiments, the fourth linear driving assembly in the present embodiment is a pneumatic cylinder. Of course, in other embodiments, the fourth linear driving assembly in the present embodiment can also be a hydraulic cylinder, a linear motor or other linear driving devices.
[0059] In some embodiments, when the tape loading platform 20 in the present embodiment is fed, the feeding disc of the feeding module continuously releases the tape, and the tension controller maintains the constant tension of the tape during the conveying process. Then, the feeding driving motor of the feeding module drives the driving feeding roller to rotate. Through the cooperative action of the driven pressing roller pressed by the elastic pressing mechanism, the tape is accurately conveyed to the second vacuum adsorption area of the tape loading platform 20 in a fixed length and is adsorbed and fixed. Next, the fourth linear driving assembly of the cutting module drives the moving cutter part to move and cooperates with the fixed cutter part to cut the tape into a preset specification. At this time, the tape feeding of the tape loading platform 20 is completed.
[0060] In some embodiments, when the adhesive tape is attached by the adhesive tape attaching device in this embodiment, the workpiece is first accurately positioned and adsorbed and fixed on the workpiece table 10, at the same time, the adhesive tape is fed to the second vacuum adsorption area of the adhesive tape table 20 in a fixed length by the feeding module and is adsorbed and fixed by the second adsorption assembly, then the driving module 40 drives the adhesive tape table 20 to move, so that the roller module 30 is positioned directly above the starting position of the adhesive tape attaching of the workpiece, then the driving module 40 drives the adhesive tape table 20 to move downward along the third direction, so that the roller module 30 is pressed against the adhesive attaching surface of the workpiece, at this time, one end of the adhesive tape in the first direction is located between the roller module 30 and the adhesive attaching surface, and is pressed and attached to the adhesive attaching surface by the roller module 30, after the roller module 30 is pressed against the surface of the workpiece, the driving module 40 drives the adhesive tape table 20 to move along the first direction, and the roller module 30 rolls accordingly, in the process of rolling and pressing, the adhesive tape is gradually peeled off from the second vacuum adsorption area and is simultaneously pressed and attached to the surface of the workpiece, after the adhesive tape is attached, the driving module 40 drives the adhesive tape table 20 to move to the edge easy warping area of the attached adhesive tape, then the driving module 40 drives the adhesive tape table 20 to move along the second direction, and the roller module 30 slides accordingly, so as to realize the sliding rolling of the attached adhesive tape, after the rolling and reinforcement of the attached adhesive tape is completed, the adhesive tape attaching device can return to the initial state to prepare for the next working cycle.
[0061] Referring to Figure 6 As shown, according to another aspect of the present application, an adhesive tape attaching method is provided, the adhesive tape attaching method adopts the adhesive tape attaching device as described above, and the adhesive tape attaching method comprises the following steps: S101, providing a semi-finished product module having an adhesive attaching surface; S103, driving the adhesive tape table 20 to move along the first direction by the driving module 40, so that the roller module 30 rolls and presses the adhesive tape to attach the adhesive tape to the adhesive attaching surface; and S105, driving the adhesive tape table 20 to reciprocate along the second direction by the driving module 40, so that the roller module 30 slides and rolls the edge easy warping area of the attached adhesive tape. By controlling the adhesive tape table 20 to move along the first direction by the driving module 40 and combining the autorotation of the roller module 30, the efficient and stable rolling and pressing of the adhesive tape on the adhesive attaching surface can be realized, by controlling the adhesive tape table 20 to reciprocate along the second direction by the driving module 40, the roller module 30 can slide and roll the edge easy warping area of the attached adhesive tape through the sliding friction between the roller module 30 and the attached adhesive tape, the adhesive tape attaching method in this embodiment can continuously complete the attachment and reinforcement of the adhesive tape at one time, the risk of air bubbles and warping of the adhesive tape attachment is eliminated, and the efficiency, precision and reliability of the adhesive tape attachment are effectively improved.
[0062] It can be understood that the adhesive attaching surface of the semi-finished product module in this embodiment comprises a planar section and a curved section located at the edge of the planar section, and the edge easy warping area of the adhesive tape refers to the corresponding area for attaching to the curved section.
[0063] In a specific embodiment, the positive pressure applied by the roller module 30 to the adhesive tape during the rolling pressing is the same as the positive pressure applied to the adhesive tape during the sliding rolling. By setting the positive pressure applied by the roller module 30 to the adhesive tape during the rolling pressing and the sliding rolling to be the same, the uniformity and consistency of the interface pressure distribution during the adhesive tape attaching process can be ensured. Specifically, during the rolling pressing, the constant positive pressure can ensure that the adhesive tape and the adhesive surface are initially attached without bubbles. During the sliding rolling, maintaining the same positive pressure can avoid the secondary displacement of the adhesive tape or the damage to the adhesive layer caused by the sudden change of the pressure, thereby improving the overall uniformity, interface bonding strength and long-term reliability of the adhesive tape attaching.
[0064] In another embodiment, the positive pressure applied by the roller module 30 to the adhesive tape during the rolling pressing is greater than the positive pressure applied to the adhesive tape during the sliding rolling. By setting the positive pressure applied by the roller module 30 to the adhesive tape during the rolling pressing to be greater than the positive pressure applied to the adhesive tape during the sliding rolling, the roller module can ensure that the adhesive tape and the adhesive surface have better initial attaching strength by the larger positive pressure of the rolling pressing, and reduce the risk of deformation or damage of the adhesive tape caused by the sliding rolling process by the smaller positive pressure of the sliding rolling.
[0065] In summary, the adhesive tape attaching device and the adhesive tape attaching method provided by the embodiment have at least the following beneficial technical effects: the adhesive tape attaching device provided by the embodiment can drive the adhesive tape stage 20 to move in the first direction or the second direction by the driving module 40. When the adhesive tape stage 20 is driven by the driving module 40 to move in the first direction, the adhesive tape stage 20 can drive the roller module 30 to move in the first direction, and the rolling pressing attaching of the adhesive tape can be realized by the rotation of the roller module 30. When the adhesive tape stage 20 is driven by the driving module 40 to move in the second direction, the adhesive tape stage 20 can drive the roller module 30 to move in the second direction, and the rolling pressing of the adhesive tape can be realized by the sliding friction between the roller module 30 and the adhesive tape, thereby reducing the probability of the adhesive tape being lifted. The adhesive tape attaching device provided by the embodiment can realize the attaching and compacting of the adhesive tape, thereby simplifying the process complexity of the adhesive tape attaching and improving the production efficiency.
