Description

Technical Field

[0001] The present invention relates to the field of automation equipment, and in particular to a fully automatic special-shaped polarizer laminating machine and a laminating process thereof. Background Art

[0002] Glass substrates and polarizers are the most basic assembly materials in the production and assembly process of mobile phone screens, TV screens and other fields. Glass substrates are used as carriers, and polarizers are attached to the surface of glass substrates to meet various optical needs. According to the characteristics of the glass substrate, it is divided into flexible screens or rigid screens. In the actual production and manufacturing process of the display, the polarizer needs to be attached to the surface of the glass substrate. With the continuous improvement of display manufacturing technology, foreign display manufacturers have gradually introduced automated production lines into screen manufacturing. Domestic screen manufacturers have also increased their investment in recent years, continuously carrying out industrial transformation and upgrading, and replacing traditional manual assembly production lines with automated production lines.

[0003] The following technical problems need to be solved in the process of upgrading the polarizer bonding automated production line: 1. Since the polarizer bonding process involves the process requirement that polarizers need to be attached to both sides of the glass substrate, traditional bonding equipment generally places the glass substrate flat on the stacking platform and then attaches the polarizer to the surface of the glass substrate. The process requirements for attaching the back of the glass substrate cannot be met, so the back side attachment problem needs to be solved. In the actual processing process, polarizers often need to be attached to both sides of the glass substrate. At this time, after attaching a piece of glass substrate, the glass substrate needs to be rotated 180° to attach the polarizer on the other side. Based on the above process requirements, it is necessary to solve the automatic connection of glass substrates between different workstations and the replacement of the glass substrate attachment surface; 2. Before attachment, it also involves the automatic loading, transfer and movement of glass substrates and polarizers; 3. The traditional attachment process is generally a single-time bonding process. , that is, after one pasting, the material is loaded and attached. This process has a standby time, that is, the polarizer cannot be attached when it is loaded, and the material cannot be loaded when it is attached; 4. Since the surface quality needs to be guaranteed before pasting to improve the subsequent pasting yield, the surface cleaning and detection problems of glass and polarizer need to be solved before pasting; 5. During the pasting process, when the polarizer made of flexible material is attached to the glass substrate, the problem of bonding bubbles needs to be solved; 6. In addition, the surface of the polarizer is covered with a protective film when it is incoming, so the problem of automatic tearing of the film before pasting needs to be solved; 7. After the polarizer is attached to the glass substrate, the position deviation that may occur during the attachment process will cause the polarizer to be attached. Position error, so the problem of polarizer attachment position accuracy needs to be solved; in particular, for special-shaped polarizers, due to their irregular size or position to be inspected, it is more difficult than traditional detection.

[0016] A laminating process of a fully automatic special-shaped polarizer laminating machine includes the following process steps:

[0017] S1. Material transfer: After the material transfer mechanism receives the glass substrate from the previous station, it drives the glass substrate to transfer 180° to the side of the loading arm;

[0024] The beneficial effects of the present invention are:

[0025] In view of the defects and shortcomings of the prior art, the present invention independently develops and designs a device that realizes the adjustment of the bonding surface of the glass substrate by automatically receiving and flipping the feeding, and uses the lower mounting belt and the upper mounting suction plate to cooperate to realize the automatic bonding of the back side of the polarizer, and effectively reduces the bonding bubbles through line contact bonding, adopts rotating polarizers and patches, reduces the waiting time, and effectively improves the production efficiency, and combines point detection and surface detection methods to effectively realize the full-automatic special-shaped polarizer bonding machine and bonding process for automatic detection of irregular surfaces.

[0026] The present invention as a whole comprises a material receiving and flipping mechanism, a material loading and moving arm, a transfer platform, a rotating patch mechanism, a polarizer loading mechanism and a material picking and film tearing patch mechanism. After the front side patch is completed at the previous workstation, the glass substrate is sucked by the material receiving and flipping mechanism and then flipped 180 degrees and transferred to the bottom of the material loading and moving arm. After being sucked by the material loading and moving arm, the glass substrate is moved to the transfer platform; the patch platform of the material picking and film tearing patch mechanism sucks the glass substrate from the transfer platform and sets it with the attachment surface facing downward. After the polarizers stacked up and down in the material box of the polarizer feeding mechanism are automatically lifted up one by one by the material box, the material picking and film tearing and pasting mechanism takes out the polarizers and places them on the polarizer transfer platform. The polarizer transfer platform drives the polarizer to be transported forward in a straight line. When passing through the polarizer detection mechanism and the cleaning mechanism, the surface is inspected and cleaned. After the inspection and cleaning, the polarizer is moved to a mounting head of the rotating mounting mechanism by the polarizer taking assembly of the material picking and film tearing and pasting mechanism. The mounting head supports the polarizer through a flexible mounting belt. At the same time, the film tearing assembly of the material picking and film tearing and pasting mechanism adheres the easy-tear sticker to the film material to be torn on the surface of the polarizer after the easy-tear sticker is taken out by the easy-tear sticker mechanism. The film tearing assembly tears the film material on the surface of the polarizer through the easy-tear sticker. After the polarizer is torn off, the rotating patch mechanism drives the mounting head to rotate and rotate to the bottom of the mounting platform of the material picking and film tearing mechanism. The mounting platform moves downward to the mounting head. The mounting head pushes the mounting belt from the bottom through the pressure roller inside it to make one side of the polarizer contact with the glass substrate line. The pressure roller remains in the top state and moves straight to the other side, so that the polarizer is completely attached to the surface of the glass substrate. When the mounting head completes the attachment, the other mounting head simultaneously performs the polarizer mounting and polarizer film tearing actions. After the mounting head completes the attachment, the two mounting heads rotate, and the mounting platform absorbs the next glass substrate at the same time for the next attachment. This rotating attachment method effectively reduces the waiting time at different workstations, improves the connection efficiency between different workstations, and greatly improves production efficiency. And the line contact patch using the above-mentioned flexible mounting belt greatly reduces the generation of bubbles during the attachment process compared to the traditional surface attachment.

[0027] The present invention designs a material receiving and flipping mechanism for the process requirements of automatic material receiving and flipping at different workstations. The material receiving and flipping mechanism is used for the automatic connection, transfer and flipping of materials between two processing stations in the polarizer attachment production line. The connecting linear module is used as a horizontal power component to drive the connecting linear slide arranged thereon to move back and forth in a direction perpendicular to the connection line of the two processing stations, thereby realizing automatic adjustment of the material receiving and feeding position. By using a rotating motor arranged on the connecting linear slide as an automatic flipping power component, the rotating motor drives the material plate to flip back and forth between the two processing stations by driving the rotating motor connected to its output end, thereby realizing the transfer and transfer of materials while flipping the materials 180°, which meets the process requirements of attaching polarizers on both sides of the glass substrate. At the same time, a plurality of installation slots are provided on the material plate, and a vacuum suction nozzle is detachably installed in the installation slot body, and the vacuum negative pressure generated by the vacuum suction nozzle is used to adsorb and fix the material. At the same time, the installation position of each vacuum suction nozzle can be adjusted in real time according to the size of the material to adapt to the adsorption of materials of various sizes, and has good versatility.

[0028] Aiming at the requirements of back-side attachment of glass substrate and film tearing process before patching, the present invention creatively designs a material picking, film tearing and patching mechanism. The material picking, film tearing and patching mechanism uses a U-shaped support frame as a bearing body, and a first linear module and a second linear module are respectively provided on the top and side wall of the support frame. The first linear module is provided with a polarizer assembly, and the second linear module is provided with a film tearing assembly and a patching platform. The first linear module and the second linear module are used as horizontal driving power mechanisms to drive the polarizer assembly, the film tearing assembly and the patch assembly in the horizontal linear direction respectively. In the actual production process, the polarizer removal assembly of the present invention realizes automatic suction and removal of the polarizer from the material box. After the film tearing assembly takes out the easy-tear sticker at the easy-tear sticker mechanism, it adheres the easy-tear sticker to the film material on the surface of the polarizer. When pulling the easy-tear sticker adhered to the surface of the film material, the film material is torn off the surface of the polarizer by the stickiness of the easy-tear sticker. At the same time, during the film tearing process of the easy-tear sticker, the auxiliary cylinder of the film tearing assembly drives the pressing block to tilt and press the polarizer downward to prevent the easy-tear sticker from pulling up the polarizer during the film tearing process, thereby ensuring the quality of film tearing. Compared with the traditional upward support method, the patch platform of the present invention sets the adsorption surface as a downward structure, and fixes the glass substrate by the patch suction plate, so that the attachment surface of the glass substrate is set downward, and the film tearing mechanism can tear off the film material on the upwardly set surface to be attached of the polarizer. The two work together, and the polarizer after film tearing can be automatically attached to the bottom surface of the glass substrate upward through the patch mechanism below, realizing automatic attachment of the reverse side.

[0029] The present invention aims at the problems of surface quality detection before attachment and attachment accuracy detection after attachment involved in the polarizer attachment process, and in particular, designs a detection mechanism for the above-mentioned problems of materials of different sizes and properties. A detection bracket vertically erected on the side of the production line is used as a bearing component, and a support plane horizontally extending to the top of the production line is provided on the top of the detection bracket; a surface detection bracket is vertically provided on the top of the side between the detection brackets, and a horizontally extending support plate is formed on the top of the surface detection bracket. A surface detection CCD with a lens facing downward is provided on the support plate. The surface detection CCD can realize the whole surface detection of the material flowing through the production line, which can be applied to surface quality detection before attachment and whole surface detection of the material after attachment. At the same time, a longitudinal drive module is provided on the top supporting plane of the detection bracket and is parallel to the side of the detection bracket. The longitudinal drive module drives the transverse drive module arranged perpendicular to it to move linearly in the longitudinal direction. At the same time, the transverse drive module drives the point detection bracket connected thereto to move linearly in the transverse direction. A point detection CCD is arranged on the point detection bracket. The position of the point detection CCD in the horizontal plane is adjusted in real time through the longitudinal and transverse direction drives. The point detection CCD can be adjusted for special parts to be inspected. At the same time, the movement path of the point detection CCD can be set according to the outer contour of the special-shaped material. Therefore, the outer contour of the special-shaped material is precisely inspected and the polarizer attachment accuracy is judged by detecting the shooting pattern of whether the polarizer is aligned with the glass substrate at the outer contour.

Fully automatic special-shaped polarizer bonding machine and bonding process.

[0093] The present invention as a whole comprises a material receiving and flipping mechanism, a material loading and moving arm, a transfer platform, a rotating patch mechanism, a polarizer loading mechanism and a material picking and film tearing patch mechanism. After the front side patch is completed at the previous workstation, the glass substrate is sucked by the material receiving and flipping mechanism and then flipped 180 degrees and transferred to the bottom of the material loading and moving arm. After being sucked by the material loading and moving arm, the glass substrate is moved to the transfer platform; the patch platform of the material picking and film tearing patch mechanism sucks the glass substrate from the transfer platform and sets it with the attachment surface facing downward. After the polarizers stacked up and down in the material box of the polarizer feeding mechanism are automatically lifted up one by one by the material box, the material picking and film tearing and pasting mechanism takes out the polarizers and places them on the polarizer transfer platform. The polarizer transfer platform drives the polarizer to be transported forward in a straight line. When passing through the polarizer detection mechanism and the cleaning mechanism, the surface is inspected and cleaned. After the inspection and cleaning, the polarizer is moved to a mounting head of the rotating mounting mechanism by the polarizer taking assembly of the material picking and film tearing and pasting mechanism. The mounting head supports the polarizer through a flexible mounting belt. At the same time, the film tearing assembly of the material picking and film tearing and pasting mechanism adheres the easy-tear sticker to the film material to be torn on the surface of the polarizer after the easy-tear sticker is taken out by the easy-tear sticker mechanism. The film tearing assembly tears the film material on the surface of the polarizer through the easy-tear sticker. After the polarizer is torn off, the rotating patch mechanism drives the mounting head to rotate and rotate to the bottom of the mounting platform of the material picking and film tearing mechanism. The mounting platform moves downward to the mounting head. The mounting head pushes the mounting belt from the bottom through the pressure roller inside it to make one side of the polarizer contact with the glass substrate line. The pressure roller remains in the top state and moves straight to the other side, so that the polarizer is completely attached to the surface of the glass substrate. When the mounting head completes the attachment, the other mounting head simultaneously performs the polarizer mounting and polarizer film tearing actions. After the mounting head completes the attachment, the two mounting heads rotate, and the mounting platform absorbs the next glass substrate at the same time for the next attachment. This rotating attachment method effectively reduces the waiting time at different workstations, improves the connection efficiency between different workstations, and greatly improves production efficiency. And the line contact patch using the above-mentioned flexible mounting belt greatly reduces the generation of bubbles during the attachment process compared to the traditional surface attachment.

[0094] The present invention designs a material receiving and flipping mechanism for the process requirements of automatic material receiving and flipping at different workstations. The material receiving and flipping mechanism is used for the automatic connection, transfer and flipping of materials between two processing stations in the polarizer attachment production line. The connecting linear module is used as a horizontal power component to drive the connecting linear slide arranged thereon to move back and forth in a direction perpendicular to the connection line of the two processing stations, thereby realizing automatic adjustment of the material receiving and feeding position. By using a rotating motor arranged on the connecting linear slide as an automatic flipping power component, the rotating motor drives the material plate to flip back and forth between the two processing stations by driving the rotating motor connected to its output end, thereby realizing the transfer and transfer of materials while flipping the materials 180°, which meets the process requirements of attaching polarizers on both sides of the glass substrate. At the same time, a plurality of installation slots are provided on the material plate, and a vacuum suction nozzle is detachably installed in the installation slot body, and the vacuum negative pressure generated by the vacuum suction nozzle is used to adsorb and fix the material. At the same time, the installation position of each vacuum suction nozzle can be adjusted in real time according to the size of the material to adapt to the adsorption of materials of various sizes, and has good versatility.

[0095] Aiming at the requirements of back-side attachment of glass substrate and film tearing process before patching, the present invention creatively designs a material picking, film tearing and patching mechanism. The material picking, film tearing and patching mechanism uses a U-shaped support frame as a bearing body, and a first linear module and a second linear module are respectively provided on the top and side wall of the support frame. The first linear module is provided with a polarizer assembly, and the second linear module is provided with a film tearing assembly and a patching platform. The first linear module and the second linear module are used as horizontal driving power mechanisms to drive the polarizer assembly, the film tearing assembly and the patch assembly in the horizontal linear direction respectively. In the actual production process, the polarizer removal assembly of the present invention realizes automatic suction and removal of the polarizer from the material box. After the film tearing assembly takes out the easy-tear sticker at the easy-tear sticker mechanism, it adheres the easy-tear sticker to the film material on the surface of the polarizer. When pulling the easy-tear sticker adhered to the surface of the film material, the film material is torn off the surface of the polarizer by the stickiness of the easy-tear sticker. At the same time, during the film tearing process of the easy-tear sticker, the auxiliary cylinder of the film tearing assembly drives the pressing block to tilt and press the polarizer downward to prevent the easy-tear sticker from pulling up the polarizer during the film tearing process, thereby ensuring the quality of film tearing. Compared with the traditional upward support method, the patch platform of the present invention sets the adsorption surface as a downward structure, and fixes the glass substrate by the patch suction plate, so that the attachment surface of the glass substrate is set downward, and the film tearing mechanism can tear off the film material on the upwardly set surface to be attached of the polarizer. The two work together, and the polarizer after film tearing can be automatically attached to the bottom surface of the glass substrate upward through the patch mechanism below, realizing automatic attachment of the reverse side.

[0096] The present invention aims at the problems of surface quality detection before attachment and attachment accuracy detection after attachment involved in the polarizer attachment process, and in particular, designs a detection mechanism for the above-mentioned problems of materials of different sizes and properties. A detection bracket vertically erected on the side of the production line is used as a bearing component, and a support plane horizontally extending to the top of the production line is provided on the top of the detection bracket; a surface detection bracket is vertically provided on the top of the side between the detection brackets, and a horizontally extending support plate is formed on the top of the surface detection bracket. A surface detection CCD with a lens facing downward is provided on the support plate. The surface detection CCD can realize the whole surface detection of the material flowing through the production line, which can be applied to surface quality detection before attachment and whole surface detection of the material after attachment. At the same time, a longitudinal drive module is provided on the top supporting plane of the detection bracket and is parallel to the side of the detection bracket. The longitudinal drive module drives the transverse drive module arranged perpendicular to it to move linearly in the longitudinal direction. At the same time, the transverse drive module drives the point detection bracket connected thereto to move linearly in the transverse direction. A point detection CCD is arranged on the point detection bracket. The position of the point detection CCD in the horizontal plane is adjusted in real time through the longitudinal and transverse direction drives. The point detection CCD can be adjusted for special parts to be inspected. At the same time, the movement path of the point detection CCD can be set according to the outer contour of the special-shaped material. Therefore, the outer contour of the special-shaped material is precisely inspected and the polarizer attachment accuracy is judged by detecting the shooting pattern of whether the polarizer is aligned with the glass substrate at the outer contour.
