Description

Technical Field

[0001] This utility model relates to the field of transfer paper correction technology, and in particular to a transfer paper correction mechanism and a patch machine. Background Technology

[0002] In the field of chip mounting machines, transfer paper, as a key carrier and transfer medium, is widely used in the mounting process of optical components such as polarizers.

[0003] Existing technologies typically employ a tensioning mechanism in conjunction with a conveyor roller to achieve the transport and positioning of transfer paper. However, during actual operation, due to factors such as inherent mechanical transmission clearances, material tension fluctuations, or cumulative path errors, the transfer paper is prone to lateral positional deviation during its travel path, a phenomenon known as misalignment. This misalignment directly results in the polarizer mounted on the transfer paper failing to precisely align with the predetermined position on the glass substrate, causing a significant decrease in the accuracy of the mounting position.

[0004] Since placement accuracy is a key factor in determining product yield, insufficient positional accuracy will directly lead to defects such as poor adhesion, bubbles, or misalignment, making it difficult to effectively guarantee the overall product yield. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is: how to effectively suppress the deviation of the transfer paper during the conveying process, so as to improve the patching accuracy and product yield.

[0006] To address the aforementioned problems, in a first aspect, this utility model provides a transfer paper correction mechanism, comprising: frame; A conveying assembly, mounted on the frame, is used to convey transfer paper; A position detection sensor is mounted on the frame and positioned on one side of the transfer paper to detect the position of the transfer paper. A position adjustment component, disposed on the frame and connected to the conveying component, is used to adjust the position of the transfer paper; The controller is connected to both the position detection sensor and the position adjustment component. The position detection sensor is configured to detect the position deviation of the transfer paper and generate a feedback signal to the controller. The controller is configured to control the position adjustment component to adjust the position of the transfer paper according to the feedback signal.

[0007] A further technical solution is that the conveying assembly includes an active roller and a driven roller, and the transfer paper is wound between the active roller and the driven roller.

[0008] A further technical solution is that the position adjustment assembly includes a first cylinder and a second cylinder, and the two ends of the driven roller are respectively connected to the first cylinder and the second cylinder.

[0013] A further technical solution includes a patch roller assembly, which is mounted on the frame and located on one side of the transfer paper.

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0024] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] See Figure 1 This utility model provides a transfer paper correction mechanism, including a frame 100, a conveying assembly, a position detection sensor 3, a position adjustment assembly, and a controller. The specific structure is described below: A conveying assembly is mounted on the frame 100 for conveying the transfer paper 1; a position detection sensor 3 is mounted on the frame 100 and located on one side of the transfer paper 1 for detecting the position of the transfer paper 1; a position adjustment assembly is mounted on the frame 100 and connected to the conveying assembly for adjusting the position of the transfer paper 1; a controller is connected to both the position detection sensor 3 and the position adjustment assembly, wherein the position detection sensor 3 is configured to detect the position deviation of the transfer paper 1 and generate a feedback signal to the controller, and the controller is configured to control the position adjustment assembly to adjust the position of the transfer paper 1 according to the feedback signal.

[0026] In practice, the edge position of the transfer paper 1 is first monitored in real time and continuously by the position detection sensor 3. This enables early identification and precise quantification of the deviation trend of the transfer paper 1, providing an accurate data basis for subsequent correction actions. When the sensor detects a positional deviation, it immediately converts it into an electrical signal and transmits it to the controller. As the processing core of the system, the controller receives this feedback signal, performs rapid calculations and judgments, and then issues corresponding control commands to the position adjustment component. Based on the command, the position adjustment component applies precise adjustment force to the conveying component, such as by fine-tuning the tension or path, thereby driving the transfer paper 1 to move in the direction that cancels the deviation, completing a closed-loop correction. This automated process from detection and judgment to execution can be completed online in real time without manual intervention, thus completely changing the outdated method of relying on regular manual inspections and adjustments.

[0027] This invention actively counteracts various deviation phenomena caused by factors such as mechanical transmission gaps, uneven material tension, or cumulative path errors, ensuring that the transfer paper 1 always travels stably along the preset theoretical path. The stability of the transfer paper 1's position directly determines the alignment accuracy of the polarizer it carries with the target area of ​​the glass substrate at the moment of attachment. Therefore, this mechanism ensures the alignment accuracy during the attachment process by maintaining the precise positioning of the transfer paper 1. The extremely high attachment alignment accuracy directly manifests as high-quality characteristics such as no bubbles, no offset, and no wrinkles in the attached product, thereby significantly reducing the defective and scrap rates caused by poor alignment.

[0028] In some preferred embodiments, the conveying assembly includes an active roller 4 and a driven roller 5, with the transfer paper 1 wound between the active roller 4 and the driven roller 5.

[0029] In specific implementation, the conveying assembly is defined as including a drive roller 4 and a driven roller 5, with the transfer paper 1 wound between them. This structure brings a stable and reliable conveying effect. The drive roller 4 provides power, and the driven roller 5 provides tension and guidance, together forming a stable conveying path, enabling the transfer paper 1 to travel smoothly and evenly.

[0030] In some preferred embodiments, the position adjustment assembly includes a first cylinder 6 and a second cylinder 7, and the two ends of the driven roller 5 are respectively connected to the first cylinder 6 and the second cylinder 7.

[0031] In practice, the position adjustment component is specifically defined as a first cylinder 6 and a second cylinder 7, which are respectively connected to the two ends of the driven roller 5, achieving precise and directional correction of the deviation of the transfer paper 1. By independently controlling the positions of the two ends of the driven roller 5, this mechanism can accurately simulate applying differentiated tensions to both sides of the transfer paper 1. For example, when the sensor detects that the transfer paper 1 has deviated to one side, the controller can instruct the first cylinder 6 or the second cylinder 7 to act, thereby slightly adjusting the position of the roller and changing the path length or tension of the transfer paper 1 on that side, thus causing the transfer paper 1 to move in the opposite direction and achieving deviation correction. This two-point independent control method, compared with single-point adjustment, can more effectively correct deviations at various tilt angles, greatly improving the accuracy and adaptability of deviation correction.

[0032] In some preferred embodiments, the position adjustment assembly further includes a first electro-proportional valve 9, which is connected to the first cylinder 6.

[0033] In specific implementation, a first electro-proportional valve 9 was added to the first cylinder 6. This improvement brought about a more precise and linear effect in air pressure control. An electro-proportional valve is a device that can continuously and precisely adjust the output air pressure according to an electrical signal. Compared to a simple on / off valve, it makes the control of the output force of the first cylinder 6 no longer a binary state of "on" or "off," but rather allows for stepless and precise adjustment within a range. This means that the controller can output a precisely matched pressure value to the first cylinder 6 through the first electro-proportional valve 9 according to the magnitude of the positional deviation, thereby achieving "micro-manipulation" of the correction force. This precise control avoids over-adjustment or under-adjustment during the correction process, allowing the transfer paper 1 to smoothly and accurately return to the target position, effectively improving the system's stability and correction accuracy.

[0034] In some preferred embodiments, the position adjustment assembly further includes a second electro-proportional valve 10, which is connected to the second cylinder 7.

[0035] In practical implementation, a second electro-proportional valve 10 was added to the second cylinder 7, achieving completely independent and precise coordinated control of the tension on both sides of the transfer paper 1. Now, both the first cylinder 6 and the second cylinder 7 are equipped with their own independent electro-proportional valves, enabling the controller to precisely adjust the height or tension at both ends of the roller in any combination. For example, when correcting complex deviation patterns, the system can simultaneously adjust the cylinder pressure at both ends by different magnitudes, thereby generating a precise resultant torque to correct the position and angle of the transfer paper 1. This dual-channel precision control capability greatly enhances the adaptability and control flexibility of the correction mechanism in dealing with various complex deviation conditions, raising the dynamic adjustment accuracy and stability of the entire system to a new level.

[0036] In some preferred embodiments, the controller is connected to the first electro-proportional valve 9 and the second electro-proportional valve 10, respectively.

[0037] In practice, the controller is connected to the first electro-proportional valve 9 and the second electro-proportional valve 10. This connection constitutes a complete dual-loop precision control system, achieving coordinated and highly automated correction actions. As the core processing unit, the controller can synchronously receive signals from the position detection sensor 3 and process output commands to the two electro-proportional valves in parallel. Based on a preset control algorithm, it can calculate an optimal combination of pressure values ​​in real time and send them to the first and second electro-proportional valves 10, directing the two cylinders to work collaboratively. This centralized control ensures the synchronicity and coordination of the correction actions, avoiding system oscillations or instability that may be caused by asynchronous signals or dispersed control logic, thus guaranteeing a fast, stable, and efficient correction process.

[0038] In some preferred embodiments, the transfer paper correction mechanism further includes an interface detection fiber 2, which is disposed on the frame 100 and connected to the controller for detecting the joints of the transfer paper 1.

[0039] In specific implementation, the interface detection fiber optic cable 2 is used to detect the joints of the transfer paper 1. This component brings the technical effect of preventive quality control. During continuous production, the roll of transfer paper 1 needs to be spliced, and there are usually changes in thickness or material at the joints. The interface detection fiber optic cable 2 can sensitively identify this joint location. When the joint is detected, it can send a signal to the controller, which can then temporarily pause the patching operation or perform special marking in subsequent processes. This function effectively prevents patching at joint locations with abnormal physical characteristics, avoiding a series of quality defects such as patch bubbles, detachment, or scratches that may result, thereby eliminating the generation of certain types of waste at the source and further ensuring and improving the final product yield.

[0040] In some preferred embodiments, the transfer paper correction mechanism further includes an interface detection optical fiber 2 and a patch roller assembly 8, which is disposed on the frame 100 and located on one side of the transfer paper 1.

[0041] In the specific implementation, a patch roller assembly 8 was added and placed on the frame 100 on one side of the transfer paper 1. The patch roller assembly 8 is a key component for completing the final patching action and can improve the reliability of patching.

[0042] In some preferred embodiments, the controller is a programmable logic controller.

[0043] In practical implementation, the Programmable Logic Controller (PLC) is a proven control core in industrial environments. Its robust structure allows it to withstand complex operating conditions such as vibration and electromagnetic interference that may occur at the pick-and-place machine, ensuring long-term stable system operation. Furthermore, the PLC's powerful programming capabilities enable the flexible and reliable implementation of complex correction control logic (such as PID control and dual-cylinder collaborative algorithms), facilitating subsequent adjustments and optimizations based on process requirements. In addition, the PLC's standard communication interface facilitates data exchange between the correction mechanism and the entire production line, enabling a higher level of automation management and thus enhancing the overall intelligence level of the production system.
