Description

Technical Field

[0001] This application relates to the field of film application technology, and in particular to a film application machine. Background Technology

[0002] Glass panels are a widely used product, especially in electronic products such as mobile phones, tablets, and televisions. Typically, after glass panels are manufactured, different films need to be applied to them for different applications. Operators need to place and fix the glass panel on a processing table, then pick up the film material and slowly apply it to the glass panel. Because these film materials are very thin, the application process requires extreme care and a high level of operator skill. However, manual application makes it difficult to reduce the flatness of the film material during the application process, easily resulting in small air bubbles or indentations, leading to reduced product quality or wasted film. Summary of the Invention

[0003] In order to improve the efficiency and pass rate of film application, this application provides a film application machine.

[0004] This application provides a film applicator, which adopts the following technical solution: A film applicator includes a base, on which a moving device, a film applicator, a feeding device, and a cutting device are mounted; The film-attaching device includes a film-attaching wheel, the interior of which is provided with a pipe for vacuum adsorption. A baffle block is fixedly provided on the surface of the film-attaching wheel, and the baffle block is essentially a rectangular block. The surface of the film-attaching wheel is also provided with a first adsorption part, a second adsorption part, and a third adsorption part. The first adsorption part, the second adsorption part, and the third adsorption part are all composed of multiple circular ventilation holes. The first adsorption part, the second adsorption part, and the third adsorption part are all connected to the vacuum adsorption pipes arranged inside the film-attaching wheel. The first adsorption part is arranged adjacent to the baffle block. The density of the ventilation holes in the second adsorption part is set to be lower than the density of the ventilation holes in the first adsorption part. The moving device includes a moving arm, which includes a first rotating fixed plate and a second sliding plate. The first rotating fixed plate and the second sliding plate are slidably connected by a screw mechanism. A suction fixture, a vacuuming device and a vision device are fixedly installed at the bottom of the second sliding plate. The suction fixture includes a suction base and a contact seat. The suction base has multiple annular grooves forming vacuum grooves, and the multiple vacuum grooves are arranged in a concentric circle pattern.

[0005] By adopting the above technical solution, and through the configuration of the film-applying wheel and the moving arm, the film-applying wheel is provided with a first adsorption section, a second adsorption section, and a third adsorption section. The first and second adsorption sections are used to directly adsorb the film material, which helps to fix the film material during application. The density of the ventilation holes in the second adsorption section is set to be lower than that in the first adsorption section, making the density of the ventilation holes in the first adsorption section higher than that in the second adsorption section. The first adsorption section is used to adsorb the edges of the film material. This configuration can improve the adsorption strength of the first adsorption section on the edges of the film material, making it easier to pull and pick up the film material. By setting the partition block, the surface of the film-applying wheel is divided, so that the film-applying wheel can only pull up one layer of film material at a time, avoiding application failure or material waste due to too many layers. By setting the moving arm, a suction fixture is provided on the moving arm, and a vacuum groove for negative pressure adsorption is provided on the suction fixture, so that the suction fixture can achieve the adsorption function of the glass panel. Through the above configuration, the equipment can achieve the adsorption function of glass panel and film material.

[0006] In one specific implementation, the film-attaching wheel has a movable slot, the third adsorption part is located at the bottom of the movable slot, and a wedge is provided inside the movable slot. The wedge includes an insertion part and a wedge-shaped part. The insertion part is inserted into the movable slot. A rubber ring is provided at one end of the insertion part near the wedge-shaped part and at the bottom of the insertion part. A magnetic block is fixedly provided on the bottom surface of the insertion part. The magnetic block and the third adsorption part form a double fixation of the wedge block by magnetic attraction and negative pressure adsorption.

[0007] By adopting the above technical solution, the wedge includes a wedge-shaped part and an insertion part. The insertion part is used to fix the wedge. The wedge shape of the wedge-shaped part allows the film material to be lifted by the wedge when it passes through the wedge, which facilitates the cutting and application of the material. The rubber ring and the magnetic block provide double security for fixing the wedge. When the equipment is stopped, the wedge can be magnetically fixed by the magnetic block. When the equipment is running, the centrifugal force generated by the rotation of the film-applying wheel provides further reinforcement.

[0008] In one specific implementation, the wedge-shaped portion is exposed on the surface of the coating wheel, and the top surface of the wedge-shaped portion is coated with a light-absorbing coating, which works in conjunction with a vision device for visual recognition.

[0009] By adopting the above technical solution, and by setting the light-absorbing coating, the light-absorbing coating can cooperate with the vision device to locate the edge position of the film material, and calibrate and position the edge of the glass panel and the edge of the film material, thereby improving the accuracy of film application.

[0010] In one specific implementation scheme, the mobile device includes a first telescopic sleeve, a second telescopic sleeve, and a moving arm. The first and second telescopic sleeves are identical, each including a fixed part and a telescopic part. The fixed part is fixedly mounted on a base, and the top of each telescopic part has a groove forming an assembly slot. A sliding column is fixedly mounted in the assembly slot on the first telescopic sleeve, and a rotary motor and a rotary column are fixedly mounted in the assembly slot on the second telescopic sleeve. The output shaft of the rotary motor is keyed to the rotary column, and the rotary motor is hidden within the assembly slot.

[0011] By adopting the above technical solution, the lifting effect of the moving arm can be achieved by setting the first telescopic sleeve and the second telescopic sleeve, and the rotation effect of the moving arm can be achieved by setting the rotating column and the rotating motor.

[0012] In one specific implementation scheme, the side of the rotating column is provided with an elongated groove to form a transmission groove. There are two transmission grooves, which are respectively opened opposite each other at both ends of the rotating column. The first rotating fixing plate is provided with a closing slide sleeve and a C-shaped sleeve at one end near the first telescopic sleeve and the second telescopic sleeve. The closing slide sleeve is fitted on the rotating column. The inner wall of the closing slide sleeve is provided with a protrusion to form a transmission tooth, which is inserted into the transmission groove.

[0013] By adopting the above technical solution and setting the transmission teeth, the transmission function can be realized, enabling the closed sliding sleeve to rotate along the rotating column, thereby driving the moving arm to achieve the technical effect of rotation.

[0014] In one specific implementation, the C-shaped sleeve is substantially shaped like the letter "C", the C-shaped sleeve is connected to the sliding post for opening and closing, and the bottom of the C-shaped sleeve and the closed sliding sleeve are in contact with the top of the telescopic part.

[0015] By adopting the above technical solution, and by setting the C-shaped sleeve, the shape of the C-shaped sleeve is actually set to the letter "C". This setting can realize the opening and closing connection between the C-shaped sleeve and the sliding column, thereby forming a connection with the closed sliding sleeve with one end fixed and the other end movable, so that the moving arm can realize the function of rotation.

[0016] In one specific implementation scheme, a push block cylinder is also fixedly provided on the side wall of the contact seat, and a calibration push block is fixedly provided on the output shaft of the push block cylinder. The calibration push block is a rectangular block, and a positioning plate for assisting the vision device in positioning is provided at the end of the contact seat opposite to the calibration push block.

[0017] By adopting the above technical solution, the calibration pusher and the positioning plate play a calibration role. The positioning plate is set adjacent to the vision device, so that the positioning plate can assist in the positioning of the vision device.

[0018] In one specific implementation, the cutting device is fixedly mounted on the base, and the cutting device includes a drive mechanism and a laser cutter, the laser cutter being used to cut the film material.

[0019] By adopting the above technical solution, the laser cutter can be used to cut the film material.

[0020] In one specific implementation, the base is further provided with a slide rail, on which a bracket is slidably mounted, and the film-attached wheel is rotatably mounted on the bracket.

[0021] By adopting the above technical solution, the slide rail enables the film-attached wheel to move.

[0022] In one specific implementation, the feeding device includes an installation roller, a tensioning roller, and a feeding roller. An extension frame is fixedly provided at the end of the base. The tensioning roller and the feeding roller are fixedly provided at the end of the base through the extension frame. Both the tensioning roller and the feeding roller are rotatably mounted on the extension frame.

[0023] By adopting the above technical solution and setting the installation roller, tensioning roller and feeding roller, the feeding setting of the film material can be realized.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up the film application device and the moving device, the film application device can achieve the technical effect of adsorbing and rolling the film application material, and the moving device can achieve the effect of moving and adsorbing the glass panel.

[0025] 2. By configuring the cutting device, the cutting device includes a laser cutter for cutting the film material. The film roller is equipped with a baffle block. When the laser cutter cuts the film material, the laser cutter can act as a baffle to prevent the laser from damaging other parts of the equipment. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0029] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0030] This application discloses a film applicator, as shown in the embodiments below. Figure 1 The system includes a base 2, on which a moving device, a film-applying device, a feeding device, and a cutting device are mounted. In this embodiment, a controller is also provided, configured as a normal controller, used to control the actuators in this application.

[0031] The feeding device includes an installation roller 43, a tensioning roller 42, and a feeding roller 45. An extension frame 46 is fixedly installed at the end of the base 2. The tensioning roller 42 and the feeding roller 45 are fixedly installed at the end of the base 2 via the extension frame 46. Both the tensioning roller 42 and the feeding roller 45 are rotatably mounted on the extension frame 46. A feeding frame 47 is fixedly connected to the end of the extension frame 46 away from the fixed plate. The installation roller 43 is rotatably mounted on the feeding frame 47. The film-applying material is installed on the installation roller 43 in roll form. The film-applying material passes through the tensioning roller 42 and the feeding roller 45 for feeding. The tensioning roller 42 tensions the film-applying material, which helps to move the film-applying material. The feeding roller 45 is provided with a rubber material to increase friction. The feeding roller 45 is set as an active roller. A motor for driving the feeding roller 45 is fixedly installed on the side end of the extension frame 46. The motor is connected to the feeding roller 45 for transmission.

[0032] Reference Figure 2 and Figure 3 The moving device includes a first telescopic sleeve 11, a second telescopic sleeve 12, and a moving arm 13. The first telescopic sleeve 11 and the second telescopic sleeve 12 are identical, each including a fixed part 111 and a telescopic part 112. The fixed part 111 is fixedly mounted on the base 2. The top of each telescopic part 112 has a groove forming an assembly groove 121. A sliding post 113 is fixedly mounted within the assembly groove 121 on the first telescopic sleeve 11, and the bottom of the sliding post 113 is threadedly connected to the assembly groove 121. A rotary motor 122 and a rotating post 123 are fixedly mounted within the assembly groove 121 on the second telescopic sleeve 12, and the output shaft of the rotary motor 122 is keyed to the rotating post 123. The rotary motor 122 is concealed within the assembly groove 121. The side of the rotating column 123 is provided with a long strip-shaped groove to form a transmission groove 124. There are two transmission grooves 124, which are opposite to each other at both ends of the rotating column 123.

[0033] The motion arm 13 includes a first rotating fixed plate 131 and a second sliding plate 135. The first rotating fixed plate 131 and the second sliding plate 135 are slidably connected by a screw mechanism. A motor for driving the screw mechanism is fixedly installed on the side end of the first rotating fixed plate 131. Through the screw mechanism and the motor, the second sliding plate 135 can move bidirectionally along the length direction of the first rotating plate.

[0034] A closing slide sleeve 132 and a C-shaped sleeve 134 are provided at one end of the first rotating fixed plate 131 near the first telescopic sleeve 11 and the second telescopic sleeve 12. The closing slide sleeve 132 and the C-shaped sleeve 134 are fixedly arranged at intervals. The closing slide sleeve 132 is designed to match the shape of the rotating column 123 and is fitted onto the rotating column 123. The inner wall of the closing slide sleeve 132 is provided with protrusions forming transmission teeth 133. When the closing slide sleeve 132 is fitted onto the rotating column 123, the transmission teeth 133 can be inserted into the transmission groove 124. Due to the setting of the transmission groove 124, when the rotating column 123 is driven to rotate by the rotating motor 122, the closing slide sleeve 132 rotates accordingly. The C-shaped sleeve 134 is essentially shaped like the letter "C". It engages with the sliding column 113. Since the diameter of the telescopic part 112 is larger than the diameter of the sliding column 113 and also larger than the diameter of the closed sliding sleeve 132, the bottoms of the C-shaped sleeve 134 and the closed sliding sleeve 132 can contact the top of the telescopic part 112. This allows the first telescopic sleeve 11 and the second telescopic sleeve 12 to simultaneously raise and lower the C-shaped sleeve 134 and the closed sliding sleeve 132. In this embodiment, the first telescopic sleeve 11 and the second telescopic sleeve 12 raise and lower synchronously. Due to the shape of the C-shaped sleeve 134, it is in movable contact with the telescopic part 112. When the rotary motor 122 drives the rotating column 123 to rotate, the rotating column 123, through the closed sliding sleeve 132, can drive the first rotating fixed plate 131 and the second sliding plate 135 to rotate, thereby enabling the moving arm 13 to rotate along the rotating column 123.

[0035] In this embodiment, the glass panel placement position and the storage area after film application are both reasonably arranged around the motion arm 13 and placed within the range that the motion arm 13 can reach automatically.

[0036] Reference Figure 4A suction fixture 136, a vacuuming device, and a vision device 138 are fixedly installed at the bottom of the second sliding plate 135. The suction fixture 136 and the vision device 138 are arranged adjacent to each other. The suction fixture 136 is used to adsorb the glass panel, and the vision device 138 is used to perform visual calibration. The suction fixture 136 includes a suction base 20 and a contact seat 14. The suction base 20 is fixedly connected to the second sliding plate 135, and the contact seat 14 is fixedly located at the end of the suction base 20 away from the second sliding plate 135. The suction base 20 is a shell structure, and the vacuuming device is fixedly installed inside the suction base 20. Multiple annular grooves are formed on the contact seat 14 to form vacuum grooves 141, and the multiple vacuum grooves 141 are arranged in a concentric circle pattern. The vacuum grooves 141 are connected to the vacuuming device through pipelines, so that the vacuum grooves 141 can form negative pressure, thereby realizing the function of adsorbing the glass panel. A pusher cylinder 143 is fixedly mounted on the side wall of the contact seat 14. A calibration pusher 142 is fixedly mounted on the output shaft of the pusher cylinder 143. The pusher cylinder 143 drives the calibration pusher 142 to move along the surface of the contact seat 14. A positioning plate 35 for assisting the vision device 138 in positioning is provided at the end of the contact seat 14 opposite to the calibration pusher 142. The positioning plate 35 is adjacent to the vision device 138. The calibration block is a rectangular block, and the position of the glass panel is corrected by the straight edge of the rectangular block.

[0037] Reference Figure 6 and Figure 7 The film-applying device includes an application wheel 3, which is used to roll and apply film to the glass panel. A slide rail 36 is provided on the base 2, and a support 37 is slidably mounted on the slide rail 36. The application wheel 3 is rotatably mounted on the support 37. A motor for driving the rotation of the application wheel 3 is also provided on the side of the support 37. The application wheel 3 is a cylindrical roller, and its interior is equipped with pipes for vacuum adsorption. A baffle block 31 is fixedly mounted along the surface of the application wheel 3. The baffle block 31 is essentially a rectangular block and serves as a barrier, specifically for blocking the film material, ensuring that the application wheel 3 can only pick up one layer of film material at a time (one layer is one circumference of the application wheel 3). The surface of the application wheel 3 has a first adsorption section 311, a second adsorption section 32, and a third adsorption section 332. The first adsorption part 311, the second adsorption part 32, and the third adsorption part 332 are all connected to the pipelines arranged inside the film-coating wheel 3. The first adsorption part 311, the second adsorption part 32, and the third adsorption part 332 are all composed of multiple circular ventilation holes. The first adsorption part 311 is arranged adjacent to the partition block 31, and the ventilation holes of the first adsorption part 311 are arranged in a row along the length direction of the film-coating wheel 3. The second adsorption part 32 is evenly distributed along the surface of the film-coating wheel 3, and the density of the ventilation holes of the second adsorption part 32 is set to be lower than the density of the ventilation holes of the first adsorption part 311.

[0038] A groove is formed on the film-attaching wheel 3 on the side of the partition block 31 opposite to the first adsorption part 311 to form a movable slot 33. The third adsorption part 332 is formed at the bottom of the movable slot 33. A wedge block 34 is provided in the movable slot 33. The wedge block 34 includes an insertion part 341 and a wedge-shaped part 343. The insertion part 341 is inserted into the movable slot 33, and the wedge-shaped part 343 is shaped like a wedge block 34 and protrudes from the surface of the film-attaching wheel 3. The wedge block 34 is adsorbed by the third adsorption part 332 through the insertion part 341, thereby fixing the wedge block 34 in the movable slot 33. A rubber ring 342 is provided at one end of the insertion part 341 near the wedge-shaped part 343 and at the bottom of the insertion part 341. The rubber ring 342 is used to improve the sealing between the insertion part 341 and the movable slot 33, thereby improving the adsorption capacity of the third adsorption part 332. The film-attached wheel 3 is made of magnetic material, and a magnetic block is fixedly installed on the bottom surface of the insertion part 341. The magnetic block is recessed in the insertion part 341. The magnetic force of the magnetic block can improve the fixing effect of the wedge 34, so that the wedge 34 forms a dual fixing effect of magnetic attraction and negative pressure adsorption, preventing it from falling off during use. When the equipment is not running, the third adsorption part 332 adsorbs, and the wedge 34 is fixed by magnetic attraction to prevent it from falling off. The magnetic fixation also makes it easy to replace the wedge 34.

[0039] The top surface of the wedge-shaped portion 343 is coated with a light-absorbing coating. The light-absorbing coating works with the vision device 138 to perform visual recognition and is used to position the relative position of the glass panel and the film material during the film application process.

[0040] Reference Figure 5 The cutting device and the feeding device are arranged opposite to each other. The cutting device is fixedly mounted on the base 2. The cutting device includes a drive mechanism and a laser cutter 51. The drive mechanism is set as a conventional slide rail 36. The laser cutter 51 is used to cut the film material.

[0041] The implementation principle of this application embodiment is as follows: The operator needs to first install the film material on the installation roller 43, place the glass panel to be filmed in the glass panel placement position, start the equipment, and the moving arm 13 realizes the rotation action through the rotating column 123, and realizes the up and down extension action through the first telescopic sleeve 11 and the second telescopic sleeve 12. The moving arm 13 first moves to the glass panel placement position, and uses the negative pressure formed by the vacuum groove 141 opened on the contact seat 14 to adsorb the glass panel. The push block cylinder 143 pushes the calibration push block 142 to push the glass panel to the positioning plate 35 for positioning.

[0042] The feeding roller works in conjunction with the film-attaching roller 3 to perform the film-attaching operation. The first adsorption part 311 first adsorbs one end of the film-attaching material, and then the film-attaching roller 3 rotates, causing the film-attaching material to be adsorbed by the second adsorption part 32. When the partition block 31 rotates to a vertical position, it means that the film-attaching roller 3 has completed the adsorption of one layer of film-attaching material. The default height of the laser cutter 51 is the same as the height when the partition block 31 is in the vertical direction. When the film-attaching roller 3 has completed the adsorption of one layer of film-attaching material, due to the setting of the wedge block 34, the end of the film-attaching material near the partition block 31 is lifted to a certain height by the wedge-shaped part 343, forming an inclined surface. The laser cutter 51 performs straight cutting on the film-attaching material. During cutting, since the partition block 31 is set behind the laser cutting of the film-attaching material, the partition block 31 can act as a barrier to prevent laser burning and damage to the equipment. After the coating material is cut, the motion arm 13 moves to the top of the coating wheel 3. The vision device 138 and the wedge 343 work together to locate and position the coating. If the position is inaccurate, the slide rail 36 at the bottom of the coating wheel 3 will move with the coating wheel 3 and align the coating material with the glass panel. Then the motion arm 13 moves down to press the edge of the glass panel against the edge of the coating material. The motor drives the coating wheel 3 to rotate, and the slide rail 36 drives the coating wheel 3 to move, so that the coating wheel 3 rotates and moves at the same time, and finally completes the coating process on the glass panel.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
