Description

Technical Field

[0001] The present invention relates to the field of automation equipment, and in particular to a fully automatic high-speed 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 lamination automated production line: 1. Since the materials involved in the polarizer lamination process include glass substrates and polarizers, the problem of automatic loading, transfer and movement of glass substrates and polarizers needs to be solved first; 2. In addition, in the actual lamination process, the process requirements for attaching polarizers to both the front and back sides of the glass substrate need to be met, so the problem of attaching the front and back sides of the glass substrate needs to be solved; 3. The traditional lamination process is generally a single lamination, that is, after lamination once, 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 lamination to improve the subsequent lamination yield, the surface detection problem of glass and polarizer needs to be solved before lamination; 5. During the lamination process, when the polarizer made of flexible material is attached to the glass substrate, the lamination bubble problem needs to be solved; 6. In addition, the surface of the polarizer is covered with a protective film when it comes, so the problem of automatic tearing of the film before lamination needs to be solved.

[0027] The beneficial effects of the present invention are:

[0028] In view of the defects and shortcomings of the prior art, the present invention independently develops and designs a fully automatic high-speed laminating machine and a laminating process thereof, which adopts two parallel mounting parts as a whole to complete the automatic attachment of the front and back polarizers on the glass substrate one by one, realizes the automatic loading, transfer and detection of the glass substrate and the polarizer, and has the functions of polarizer transfer and film tearing in one. It adopts a rotating method for taking polarizers and mounting, effectively reduces the waiting time and improves the mounting efficiency.

[0029] The present invention is designed and developed for the automatic polarizer attachment technology. The first mounting part and the second mounting part which are arranged in parallel along a straight line are used as mounting execution devices. The two mounting parts are connected by a transfer platform. The transfer platform can realize 180° rotation through motor drive to rotate and replace the attachment surface of the glass substrate. The glass substrate of the previous workstation is moved to the transfer platform of the first mounting part for feeding. After the first mounting part completes the attachment of one side of the glass substrate, the glass substrate is connected through the transfer platform of the second mounting part, and the glass substrate is rotated 180° so that the non-attached surface of the glass substrate faces upward, and then the mounting process is carried out through the second mounting part. The first mounting part and the second mounting part have the same overall structure and have good versatility.

[0030] The first mounting part and the second mounting part of the present invention as a whole include a polarizer feeding mechanism, a transfer film tearing mechanism, a mounting mechanism, a transfer platform, a glass feeding detection mechanism and a mounting platform; the polarizer feeding mechanism and the transfer platform are respectively arranged on both sides of the machine, the glass feeding detection mechanism is located on the side of the transfer platform, and extends linearly along the side direction of the machine; the glass substrate on the transfer platform is moved to the detection platform for detection by the feeding linear module of the glass feeding detection mechanism, and then moved to the mounting platform for polarizer to be attached by the material taking component of the glass feeding detection mechanism; the polarizer stacked up and down in the material box of the polarizer feeding mechanism is taken out by the feeding detection component of the polarizer feeding mechanism and placed in the polarizer After the inspection on the transfer platform, the loading inspection component moves the polarizer to the film tearing support of the transfer film tearing mechanism. The film tearing component of the transfer film tearing mechanism takes out the film tearing tape from the film tearing tape component, adheres the film tearing tape to the protective film material at the bottom of the polarizer, and makes the film tear off the polarizer after the film tearing tape adheres to the film material through the relative linear motion between the film tearing component and the film tearing support. The polarizer after film tearing is taken out by one mounting head of the mounting mechanism, while the other mounting head of the mounting mechanism attaches the polarizer to the glass substrate on the mounting platform. After the mounting is completed, the two mounting heads rotate and the empty mounting head takes the polarizer, while the full mounting head attaches the polarizer to the glass substrate. This cycle is alternated to realize the rotational polarizer attachment. Specifically:

[0031] In order to solve the problem of automatic loading, transfer and movement of polarizers, the present invention designs a polarizer loading mechanism, which as a whole includes a material box, a loading detection component and a polarizer transfer platform. The material box of the present invention uses a material box support plate as a bearing structure, and an adjustment slide groove is provided on the material box support plate. By detachably installing a limit plate on the strip slide groove, a storage space is formed by utilizing the space between the limit plates to store multiple polarizers stacked up and down. In the storage space, the material plate is used as a bearing component to support the polarizer. At the same time, the material plate is driven by a push rod through the bottom push cylinder to push up the polarizers one by one, so that the upper loading detection component can take out the top polarizer one by one. The feeding detection component of the present invention integrates the functions of taking polarizer, removing static electricity and releasing polarizer at the same time. The feeding detection component uses a linear module as a bearing and power component. The linear module is connected with a feeding component and a moving detection component. The feeding component and the moving detection component adsorb the polarizer through the vacuum negative pressure adsorption principle. Among them, after the feeding component takes out the polarizers from the material box one by one and places them on the polarizer transfer platform, the moving detection component detects the polarizer so as to screen out defective products; at the same time, the static electricity removal component arranged on the outer side of the linear module and extending downward removes static electricity from the polarizer through plasma. The polarizer that has been removed static electricity and detected is sucked from the polarizer transfer platform by the moving detection component and moved to the film tearing transfer mechanism for subsequent film tearing action. The feeding detection component realizes the actions of taking and releasing polarizer at the same time through a set of linear modules, and completes the surface detection and static electricity removal of the polarizer while taking and placing the polarizer. It effectively simplifies the structure and reduces the equipment manufacturing cost under the premise of ensuring the realization of functions.

[0032] In response to the film tearing process requirements before polarizer pasting, the present invention is innovatively designed with a film tearing transfer mechanism, which integrates the functions of the traditional independently designed film tearing tape mechanism, the film tearing mechanism and the polarizer platform into one. The present invention uses a film tearing linear module and a film tearing bracket arranged in parallel and at intervals as a bearing mechanism, and a film tearing support platform is arranged on the film tearing linear module and the film tearing bracket, and is driven by the film tearing linear module to move back and forth along a linear slide rail arranged on the film tearing bracket. In particular, the side edges of the rectangular film tearing support platform are inclined to the direction of the linear slide rail, that is, the corners of the film tearing support platform are located in the sliding channel of the film tearing support platform. This structural design enables the film tearing tape to be torn from the corners of the polarizer placed on the film tearing support platform during subsequent film tearing. This diagonal film tearing method can reduce the pulling force of the film material on the polarizer during film tearing, thereby improving the film tearing quality. In addition, the present invention provides a film tearing tape component and a film tearing component on the side of the film tearing bracket, i.e., the film tearing linear module. The film tearing tape component automatically guides out and recycles the film tearing tape with the film tearing tape adhered thereto. During the process of guiding out the film tearing tape, the film tearing component adheres the film tearing tape to the bottom of the film material at the bottom of the polarizer from below. At the same time, after the patch mechanism sucks the polarizer on the film tearing support from above, the film tearing support and the film tearing component move linearly relative to each other, so that the film material is torn off from the bottom of the polarizer.

[0033] In view of the situation that there is a waiting time between feeding and patching in the traditional polarizer bonding process, which leads to low production efficiency, the present invention innovatively designs a patch mechanism. The patch mechanism of the present invention adopts a rotation design, and uses a rotation motor with an output end facing upward as a power output component. The rotation motor drives the rotation support and the rotating support to rotate, and the placement heads symmetrically arranged on both sides of the rotating support rotate back and forth between the patch platform and the film tearing support with the rotating support. When one placement head takes out the polarizer from the film tearing support and tears the film, the other placement head attaches the absorbed polarizer to the glass substrate on the patch platform. The two placement heads synchronously realize the actions of taking out and sticking the polarizer, and the next rotation is carried out after completion, thereby effectively reducing the overall standby time and greatly improving the polarizer bonding efficiency. In addition, the mounting head of the present invention adopts the roller-belt attachment principle, and uses a flexible roller-belt to take and attach the polarizer. The roller-belt is tensioned by a fixed roller assembly and a movable roller assembly to maintain the flatness of its bottom after tensioning. At the same time, the movable roller assembly can also adjust the tension of the roller-belt in real time. A pressure roller assembly is also provided between the fixed roller assembly and the movable roller assembly. After the pressure roller of the pressure roller assembly presses against the roller-belt from above, the pressure roller moves linearly above the roller-belt during the attachment, and the polarizer is gradually attached to the glass substrate. This flexible attachment method not only protects the polarizer, but also realizes line contact attachment compared to the traditional surface contact attachment, and effectively solves the problem of bubbles easily generated between the polarizer and the glass substrate during the attachment process; and the pressure roller realizes real-time adjustment of the tension through the adjustment cylinder and the adjustment roller to adapt to the situation of tension changes in the actual production process.

[0034] In view of the automatic feeding, cleaning and detection process requirements of the glass substrate, the present invention is innovatively designed with a glass feeding detection mechanism, which integrates the functions of automatic glass substrate placement, glass substrate surface detection and cleaning. The glass feeding detection mechanism uses the feeding mechanism as the main part, and the feeding linear module of the feeding mechanism connects the transfer platform and the patch mechanism in a linear direction to form a glass substrate logistics path. After the glass substrate that flows out from the previous workstation to the transfer platform is taken out to the detection platform by the feeding component of the feeding mechanism, the detection plane drives the glass substrate to move linearly toward the patch mechanism, and passes through the first detection component and the second detection component, thereby realizing the automatic detection of the surface of the glass substrate. In particular, the present invention integrates a first detection component and surface detection for glass substrate surface detection. Since the size range of glass substrates is relatively large, such as smart watches, mobile phones, computers, and tablets are relatively small, while the size of TV screens is large, in order to adapt to surface detection of different sizes, for large-size screens, the first detection component only detects the corners of the rectangular screen to determine the position and angle placement of the screen, and at the same time combines surface detection to detect the surface quality of the screen, thereby covering the detection needs of the entire screen and greatly improving the detection quality compared to the prior art.

[0098] Furthermore, the present invention designs a fully automatic high-speed laminating machine and its laminating process that adopts two parallel-arranged mounting parts to complete the automatic attachment of polarizers on the front and back sides of the glass substrate one by one, realizes the automatic loading, transfer and detection of the glass substrate and the polarizer, and has the functions of polarizer transfer and film tearing in one. It adopts a rotating method for taking polarizers and mounting, effectively reducing the waiting time and improving the mounting efficiency.

[0099] The present invention is designed and developed for the automatic polarizer attachment technology. The first mounting part and the second mounting part which are arranged in parallel along a straight line are used as mounting execution devices. The two mounting parts are connected by a transfer platform. The transfer platform can realize 180° rotation through motor drive to rotate and replace the attachment surface of the glass substrate. The glass substrate of the previous workstation is moved to the transfer platform of the first mounting part for feeding. After the first mounting part completes the attachment of one side of the glass substrate, the glass substrate is connected through the transfer platform of the second mounting part, and the glass substrate is rotated 180° so that the non-attached surface of the glass substrate faces upward, and then the mounting process is carried out through the second mounting part. The first mounting part and the second mounting part have the same overall structure and have good versatility. The first mounting part and the second mounting part of the present invention as a whole include a polarizer feeding mechanism, a transfer film tearing mechanism, a mounting mechanism, a transfer platform, a glass feeding detection mechanism and a mounting platform; the polarizer feeding mechanism and the transfer platform are respectively arranged on both sides of the machine, the glass feeding detection mechanism is located on the side of the transfer platform, and extends linearly along the side direction of the machine; the glass substrate on the transfer platform is moved to the detection platform for detection by the feeding linear module of the glass feeding detection mechanism, and then moved to the mounting platform for polarizer to be attached by the material taking component of the glass feeding detection mechanism; the polarizer stacked up and down in the material box of the polarizer feeding mechanism is taken out by the feeding detection component of the polarizer feeding mechanism and placed in the polarizer After the inspection on the rotating platform, the loading inspection component moves the polarizer to the film tearing support platform of the transfer film tearing mechanism. After the film tearing component of the transfer film tearing mechanism takes out the film tearing tape from the film tearing tape component, it adheres the film tearing tape to the protective film material at the bottom of the polarizer, and through the relative linear motion of the film tearing component and the film tearing support platform, the film material is torn off the polarizer after the film tearing tape adheres to the film material; the polarizer after film tearing is taken out by a mounting head of the mounting mechanism, and at the same time, the other mounting head of the mounting mechanism attaches the polarizer to the glass substrate on the mounting platform. After the mounting is completed, the two mounting heads rotate and rotate, the empty mounting head takes the polarizer, and the full mounting head attaches the polarizer to the glass substrate, and the rotating polarizer attachment is realized in this cycle. Specifically: Aiming at the problem of automatic loading, transfer and movement of polarizers, the present invention designs a polarizer loading mechanism, which as a whole includes a material box, a loading detection component and a polarizer transfer platform; the material box of the present invention uses a material box support plate as a bearing structure, and an adjustment slide groove is opened on the material box support plate. By detachably installing a limit plate on the strip slide groove, a storage space is formed by utilizing the space between the limit plates to store multiple polarizers stacked up and down. The material plate is used as a bearing component in the storage space to bear and support the polarizer. At the same time, the material plate is driven by the ejection cylinder at the bottom to push up the ejection rod, thereby pushing the polarizers upward one by one, so that the upper loading detection component can take out the top polarizer one by one.The feeding detection component of the present invention integrates the functions of taking polarizer, cleaning polarizer and placing polarizer. The feeding detection component uses a linear module as a bearing and power component. The linear module is connected with a feeding component and a moving detection component. The feeding component and the moving detection component adsorb the polarizer through the vacuum negative pressure adsorption principle. Among them, after the feeding component takes out the polarizers from the material box one by one and places them on the polarizer transfer platform, the moving detection component detects the polarizer so as to screen out defective products; at the same time, the static electricity removal component arranged on the outside of the linear module and extending downward cleans the surface of the polarizer through plasma. The polarizer that has been cleaned and detected is sucked from the polarizer transfer platform by the moving detection component and moved to the film tearing transfer mechanism for subsequent film tearing action. The feeding detection component of the present invention realizes the actions of taking and placing polarizer at the same time through a set of linear modules, and completes the surface detection and cleaning of the polarizer while taking and placing the polarizer. It effectively simplifies the structure and reduces the equipment manufacturing cost under the premise of ensuring the realization of the functions. In response to the film tearing process requirements before polarizer bonding, the present invention is innovatively designed with a film tearing transfer mechanism, which integrates the functions of the traditional independently designed film tearing tape mechanism, the film tearing mechanism and the polarizer platform into one. The film tearing transfer mechanism of the present invention uses a film tearing linear module and a film tearing bracket arranged in parallel and at intervals as a bearing mechanism, and a film tearing support platform is arranged on the film tearing linear module and the film tearing bracket, and is driven by the film tearing linear module to move back and forth along a linear slide rail arranged on the film tearing bracket. In particular, the side edges of the rectangular film tearing support platform are inclined to the direction of the linear slide rail, that is, the corners of the film tearing support platform are located in the sliding channel of the film tearing support platform. This structural design enables the film tearing tape to be torn from the corners of the polarizer placed on the film tearing support platform during subsequent film tearing. This diagonal film tearing method can reduce the pulling force of the film material on the polarizer during film tearing, thereby improving the film tearing quality. In addition, the film tearing transfer mechanism of the present invention is respectively provided with a film tearing tape component and a film tearing component on the side of the film tearing bracket, i.e., the film tearing linear module. The film tearing tape component automatically guides out and recycles the film tearing tape with the film tearing tape adhered thereto. In the process of guiding out the film tearing tape, multiple pieces of film tearing tape adhered to the film tearing tape at intervals are torn off the film tearing tape by the film tearing component. Then, the film tearing component adheres the film tearing tape to the bottom of the film material at the bottom of the polarizer from below. At the same time, after the film pasting mechanism sucks the polarizer on the film tearing support from above, the film tearing support and the film tearing component move linearly relative to each other, so that the film material is torn off from the bottom of the polarizer.In view of the situation that there is a waiting time between feeding and patching in the traditional polarizer bonding process, which leads to low production efficiency, the present invention innovatively designs a patch mechanism. The patch mechanism of the present invention adopts a rotation design, and uses a rotation motor with an output end facing upward as a power output component. The rotation motor drives the rotation support and the rotating support to rotate, and the placement heads symmetrically arranged on both sides of the rotating support rotate back and forth between the patch platform and the film tearing support with the rotating support. When one placement head takes out the polarizer from the film tearing support and tears the film, the other placement head attaches the absorbed polarizer to the glass substrate on the patch platform. The two placement heads synchronously realize the actions of taking out and sticking the polarizer, and the next rotation is carried out after completion, thereby effectively reducing the overall standby time and greatly improving the polarizer bonding efficiency. In addition, the mounting head of the present invention adopts the roller-belt attachment principle, and uses a flexible roller-belt to take and attach the polarizer. The roller-belt is tensioned by a fixed roller assembly and a movable roller assembly to maintain the flatness of its bottom after tensioning. At the same time, the movable roller assembly can also adjust the tension of the roller-belt in real time. A pressure roller assembly is also provided between the fixed roller assembly and the movable roller assembly. After the pressure roller of the pressure roller assembly presses against the roller-belt from above, the pressure roller moves linearly above the roller-belt during the attachment, and the polarizer is gradually attached to the glass substrate. This flexible attachment method not only protects the polarizer, but also realizes line contact attachment compared to the traditional surface contact attachment, and effectively solves the problem of bubbles easily generated between the polarizer and the glass substrate during the attachment process; and the pressure roller realizes real-time adjustment of the tension through the adjustment cylinder and the adjustment roller to adapt to the situation of tension changes in the actual production process. In view of the automatic feeding, cleaning and detection process requirements of the glass substrate, the present invention is innovatively designed with a glass feeding detection mechanism, which integrates the functions of automatic glass substrate placement, glass substrate surface detection and cleaning. The glass feeding detection mechanism uses the feeding mechanism as the main part, and the feeding linear module of the feeding mechanism connects the transfer platform and the patch mechanism in a linear direction to form a glass substrate logistics path. After the glass substrate that flows out from the previous workstation to the transfer platform is taken out to the detection platform by the feeding component of the feeding mechanism, the detection plane drives the glass substrate to move linearly toward the patch mechanism, and passes through the first detection component and the second detection component, thereby realizing the automatic detection of the surface of the glass substrate. In particular, the present invention integrates a first detection component and surface detection for glass substrate surface detection. Since the size range of glass substrates is relatively large, such as smart watches, mobile phones, computers, and tablets are relatively small, while the size of TV screens is large, in order to adapt to surface detection of different sizes, for large-size screens, the first detection component only detects the corners of the rectangular screen to determine the position and angle placement of the screen, and at the same time combines surface detection to detect the surface quality of the screen, thereby covering the detection needs of the entire screen and greatly improving the detection quality compared to the prior art.At the same time, the present invention also integrates a surface cleaning function. The plasma box supported by the connecting rod is arranged to tilt toward the glass substrate below. The glass substrate placed on the detection platform is automatically cleaned from both sides by plasma, which effectively ensures the subsequent screen bonding quality.
