Description

Technical Field

[0001] This utility model relates to the field of glass film technology, and in particular to a glass film application mechanism for processing mobile phone front cover glass. Background Technology

[0002] In some manufacturing processes of mobile phone front cover glass, it is often necessary to apply a protective film to the glass surface to prevent scratches and avoid dust adhesion affecting subsequent processes. Chinese invention patent (CN106542142A) discloses a film application device, which includes a base plate for vacuum adsorption of the screen (glass sheet), a suction plate located above the base plate for vacuum adsorption of the film, and a rolling mechanism located between the base plate and the suction plate. During film application, the suction plate drives the film to press down and contact the screen on the base plate, while the rollers of the rolling mechanism press the film onto the film. The base plate is driven to move relative to the suction plate through a slide rail mechanism to complete the screen film application. In this device, the rollers and suction plate move up and down synchronously, and the rollers are located on one side of the suction plate. When applying the film, the rollers roll and press the film onto the upper surface of the screen from one side. When the rollers roll and come into contact with the edge of the film, they can easily lift the edge of the film, causing the edge of the film to not adhere firmly to the edge of the screen. This results in air bubbles appearing at the edge of the screen where the film is applied, affecting the quality of the screen film application and leading to a high defect rate.

[0031] In order to make the above purpose, features and advantages of the utility model more apparent, obvious and easy to understand, the specific implementation of the utility model will be described in detail below with the drawings. In the following description, a lot of specific details are set forth in order to fully understand the utility model. But the utility model can be implemented in many other ways different from the description, and the person skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0032] Please refer to Figure 1The utility model discloses a glass film pasting mechanism that can improve film pasting quality and film pasting yield, which is used for pasting a layer of high-precision protective film (film sheet) on the surface of a glass sheet. The glass film pasting mechanism is used for being installed on a mechanical hand that can move at least in the film pasting direction of the glass sheet. In other words, the glass film pasting mechanism is fixed on an external mechanical hand. The external mechanical hand comprises a fixed part, a transmission mechanism connected with the fixed part, and a clamping part connected with the transmission mechanism. The glass film pasting mechanism is fixedly connected with the clamping part. The clamping part can move at least in the film pasting direction of the glass sheet under the drive of the transmission mechanism, so as to drive the glass film pasting mechanism to suck and paste the film sheet. In the scheme, the mechanical hand used for driving the glass film pasting mechanism to move in the film pasting direction of the glass sheet can be a commercially available six-axis mechanical hand, a four-axis mechanical hand, or other driving mechanisms that can drive the glass film pasting mechanism to move in the film pasting direction of the glass sheet. The film pasting direction of the glass sheet is the left-right direction of the mechanism shown in Figure 3 and Figure 4 The vertical direction is the up-down direction of the mechanism shown in Figure 3 and Figure 4 .

[0033] Specifically, please refer to Figures 1-4The glass film pasting mechanism of the embodiment comprises a first lifting module 100, a mounting frame 200, a second lifting module 300, a horizontal movement module 400, a roller 500, a first suction plate 600, a second suction plate 700 and a main controller (not shown in the figure). The first lifting module 100 is installed on the gripping part of an external mechanical arm, and the first lifting module 100 has a first lifting part. The mounting frame 200 is fixed on the first lifting part. The second lifting module 300 is located on one side of the mounting frame 200 and is fixedly connected with the mounting frame 200. The second lifting module 300 has a second lifting part. The horizontal movement module 400 is located on the other side of the mounting frame 200 and is fixedly connected with the mounting frame 200. The horizontal movement module 400 has a horizontal movement part which can move along the direction of pasting the film on the glass sheet. The horizontal movement part is provided with a support 800 which extends towards the second lifting module 300. The roller 500 is located beside the mounting frame 200. The roller 500 is rotatably installed on the second lifting part and is lifted by the second lifting part. The first suction plate 600 is fixed on the bottom of the mounting frame 200. The first suction plate 600 is provided with a plurality of first suction holes 610 which are in communication with an external air pressure device. The plurality of first suction holes 610 penetrate the lower surface of the first suction plate 600 and form a first film suction plane on the lower surface of the first suction plate 600 for adsorbing the main body of the film 10. The second suction plate 700 is fixed on the support 800 and is located below the roller 500. The second suction plate 700 is provided with a plurality of second suction holes 710 which are in communication with the external air pressure device. The plurality of second suction holes 710 penetrate the lower surface of the second suction plate 700 and form a second film suction plane on the lower surface of the second suction plate 700 for adsorbing one side edge of the film 10. The second film suction plane is flush with the first film suction plane. The main controller is electrically connected with the first lifting module 100, the second lifting module 300 and the horizontal movement module 400. When the horizontal movement part is lowered, the support 800 and the second suction plate 700 are driven to move away from the first suction plate 600, so that a roller lifting channel is formed between the first suction plate 600 and the second suction plate 700. Preferably, the main controller is a PLC controller. Alternatively, the main controller can be a single-chip microcomputer. In this scheme, the second film suction plane is flush with the first film suction plane, which facilitates the flattening of the film 10 on the first film suction plane and the second film suction plane and prevents wrinkles from being generated on the film.

[0034] In this embodiment, the first lifting module 100 is used to drive the first suction plate 600, the second suction plate 700, and the roller 500 to rise and fall, so that the film 10 adsorbed on the first suction plate 600 and the second suction plate 700 can descend to contact the glass sheet 20 to be coated, and to raise the first suction plate 600, the second suction plate 700, and the roller 500 to leave the glass sheet after coating, so as to carry out the coating operation on the next glass sheet. The second lifting module 300 is used to drive the roller 500 to rise and fall relative to the first suction plate 600 and the second suction plate 700, so that the roller 500 rises before and after the coating operation, so that the first suction plate 600 and the second suction plate 700 jointly adsorb and unfold the film 10, and to lower the roller 500 during coating, so that the roller 500 presses down from above the film 10 and contacts the edge of the film 10. The transverse module 400 is used to drive the second suction plate 700 to approach or move away from the first suction plate 600, so that the second suction plate 700 together adsorbs the film 10 when it is in contact with the first suction plate 600, and so that when the second suction plate 700 leaves the first suction plate 600, a roller lifting channel is left between the second suction plate 700 and the first suction plate 600, so that the roller 500 descends to abut against the edge of the film 10 and gradually rolls the film 10 and the glass sheet.

[0035] During the lamination process of the film 10, an external robotic arm first moves the glass lamination mechanism to above the film storage station. The main controller then controls the first lifting module 100 to lower the remaining components on the mounting frame 200 as a whole (or the robotic arm can lower the glass lamination mechanism as a whole). During this process, the first suction hole 610 of the first suction plate 600 and the second suction hole 710 of the second suction plate 700 are connected to an external air pressure device, creating a negative pressure at the first and second film adsorption planes. Thus, the film at the film storage station adheres to the first and second film adsorption planes under the negative pressure. Subsequently, the main controller controls the first lifting module 100 to lift the remaining components on the mounting frame 200, causing the mounting frame 200 and the remaining components on it to rise as a whole (or the robotic arm can raise the glass lamination mechanism as a whole) away from the film storage station. The robotic arm then drives the glass lamination mechanism to move above the glass sheet 20 to be laminationd. Next, the main controller drives the first lifting module 100 again, causing the remaining components mounted on the mounting bracket 200 to descend to a preset height. The lateral movement module 400, driven by the main controller, moves the bracket 800, causing the second suction plate 700 to move away from the first suction plate 600 until the second suction plate 700 completely leaves the edge of the film. At this point, the edge of the film 10 contacts the glass sheet. Then, the second lifting module 300, controlled by the main controller, moves the second lifting unit, causing the roller 500 to descend until it contacts the film 10. After the roller 500 contacts the film 10, the robotic arm moves the entire glass film application mechanism along the film application direction. Figure 3 and Figure 4 Moving from center to right, during this process, the first suction plate 600 continuously adsorbs the film 10. The film 10 is tensioned under the combined action of the first suction plate 600 and the roller 500. Driven by the robot arm, the roller 500 flattens the various parts of the film 10 onto the surface of the glass sheet. After the film is applied, the main controller controls the first lifting module 100, the second lifting module 300, and the transverse module 400 to reset and return to the film 10 storage station to grab the film 10 again. This cycle continues until the film application operation on all glass sheets is completed.

[0036] The glass film application mechanism of this utility model has a liftable roller 500 and a second suction plate 700 that can move closer to or further away from the first suction plate 600, which can be arranged beside the first suction plate 600. When applying the film, the roller 500 can be raised and lowered by moving the second suction plate 700 to release the restriction of the second suction plate 700 on the film. This allows the roller 500 to contact the edge of the film 10 from above and apply the film 10 to the glass sheet. This replaces the film application method of rolling the roller 500 onto the film from the side. It can avoid the problems of film edge warping and poor adhesion between the film edge and the glass sheet, prevent air bubbles from appearing at the film application area of ​​the glass sheet, and improve the film application quality and yield.

[0037] Please combine Figures 1-4 The first lifting module 100 includes a mounting platform 110 for fixing to the gripper of a robotic arm, a servo motor 120 fixed to the top or bottom of the mounting platform 110 and electrically connected to the main controller, a ball screw (not shown) driven by the output shaft of the servo motor 120 and arranged vertically, a first slide rail 130 fixed to the mounting platform 110 and extending vertically, and a first slider 140 fixedly connected to the ball nut of the ball screw and slidably engaged with the first slide rail 130. The first slider 140 forms the first lifting part and is fixedly connected to the mounting frame 200. In this embodiment, the ball screw includes a lead screw and a ball nut sleeved on the lead screw and threadedly engaged with the lead screw. During the rotation of the lead screw, due to the threaded connection between the lead screw and the ball nut, the ball nut will shift along the length direction of the lead screw, thereby converting the rotation of the lead screw into the linear motion of the ball nut, so that the ball nut can drive the first slider 140 and the mounting frame 200 to rise and fall. By sliding the first slider 140 against the first slide rail 130, the path of the first slider 140 along the mounting platform 110 can be limited, thereby reducing the shaking of the first suction plate 600, the second suction plate 700, and the roller 500 during the lifting process, so that the film 10 can be aligned with the glass to be coated. In other embodiments, the first lifting module 100 can also be a cylinder, an electric cylinder, or a hydraulic cylinder, with the piston rod of the cylinder, electric cylinder, or hydraulic cylinder serving as the first lifting part of the first lifting module 100. Of course, the first lifting module 100 can also be replaced with other commercially available linear modules, which will not be described in detail here.

[0038] Furthermore, the first lifting module 100 also includes a coupling (not shown in the figure), which is connected to the output shaft of the servo motor 120 and the lead screw of the ball screw, respectively. That is, one end of the coupling is fixedly connected to the output shaft of the servo motor 120, and the other end of the coupling is fixedly connected to the lead screw of the ball screw, and the axes of the three are collinear. In addition, the first lifting module 100 also includes a first slotted photoelectric switch 150 fixed on one side of the mounting platform 110 and located in a first position, and a second slotted photoelectric switch 160 fixed on the other side of the mounting platform 110 and located in a second position. A first baffle 141 corresponding to the first slotted photoelectric switch 150 is fixed on one side of the first slider 140, and a second baffle 142 corresponding to the second slotted photoelectric switch 160 is fixed on the other side of the first slider 140. The horizontal height of the first position is higher than the horizontal height of the second position. The first slotted photoelectric switch 150 and the second slotted photoelectric switch 160 are electrically connected to the main controller. In other words, the first slotted photoelectric switch 150 is located above the second slotted photoelectric switch 160. In this solution, by setting the first slotted photoelectric switch 150 and the second slotted photoelectric switch 160, it is beneficial to control the lifting range of the mounting bracket 200 and the components on the mounting bracket 200.

[0039] Specifically, during the downward movement of the first slider 140 driven by the ball nut, when the second baffle 142 passes through the beam-emitting area (the area between the infrared emitter and the infrared receiver) of the second slotted photoelectric switch 160, the infrared light emitted by the infrared emitter of the second slotted photoelectric switch 160 is blocked by the second baffle 142. The infrared receiver of the second slotted photoelectric switch 160 fails to receive the signal emitted by the infrared emitter, and the potential at the second slotted photoelectric switch 160 changes. The main controller then controls the servo motor 120 to stop working to avoid damage or breakage of the glass due to the continuous downward movement of the first suction plate 600 and the second suction plate 700. Similarly, as the first slider 140 moves upward under the action of the ball nut, when the first baffle 141 passes through the beam-emitting area (the area between the infrared transmitter and the infrared receiver) of the first slotted photoelectric switch 150, the infrared light emitted by the infrared transmitter of the first slotted photoelectric switch 150 is blocked by the first baffle 141. The infrared receiver of the first slotted photoelectric switch 150 fails to receive the signal emitted by the infrared transmitter, and the potential at the first slotted photoelectric switch 150 changes. The main controller then controls the servo motor 120 to stop working to avoid the problem of the mounting bracket 200 impacting the servo motor 120 due to the excessive distance of the first slider 140 rising, thus ensuring the safety of the operation.

[0040] In one embodiment, the mounting bracket 200 includes a module adapter plate 210 located on the side of the first slider 140 facing away from the mounting platform 110 and fixedly connected to the first slider 140; two ribs 220 oppositely disposed and fixedly connected to the side of the module adapter plate 210 facing away from the first slider 140; and a transition cross plate 230 located below the module adapter plate 210 and fixedly connected to the bottom of the module adapter plate 210 and the bottom of the ribs 220. The dimensions of the ribs 220 gradually increase from top to bottom along the glass sheet lamination direction (the thickness direction of the module adapter plate 210). That is, the ribs 220 have a triangular plate structure and are used as reinforcing ribs to improve the overall mechanical strength of the mounting bracket 200.

[0041] Please combine Figures 1-4 as well as Figure 7 The second lifting module 300 includes a cylinder mounting plate 310 fixed on the transition horizontal plate 230 and arranged vertically, a first cylinder 320 fixed on the cylinder mounting plate 310, a first solenoid valve group disposed on the connecting pipe between the first cylinder 320 and the external air pressure device and electrically connected to the main controller, and an n-shaped connecting frame 330 located below the first cylinder 320 and fixedly connected to the piston rod of the first cylinder 320. The n-shaped connecting frame 330 forms the second lifting part. The n-shaped connecting frame 330 includes two vertical parts arranged opposite each other and a horizontal part fixedly connected to the top of the two vertical parts. A roller 500 is located between the two vertical parts and rotatably connected to the two vertical parts. Furthermore, the first solenoid valve group includes a first intake valve disposed on the intake pipe of the first cylinder 320 and a first exhaust valve disposed on the exhaust pipe of the first cylinder 320. The main controller controls the intake and exhaust of the first cylinder 320 by controlling the opening and closing of the first intake valve and the first exhaust valve, thereby realizing the lifting and lowering control of the piston rod of the first cylinder 320. In this embodiment, a rotating shaft passes through the two vertical parts, one end of the rotating shaft is fixedly connected to one vertical part, and the other end of the rotating shaft is fixedly connected to the other vertical part. The roller 500 is rotatably sleeved on the rotating shaft. Of course, the roller 500 can also be fixedly sleeved on the rotating shaft, and the rotating shaft can be rotatably engaged with the two vertical parts. To improve the smoothness of the roller 500's lifting and lowering, a second slide rail 340 is fixed on the side of the cylinder mounting plate 310 facing away from the module adapter plate 210. A second slider 350 is fixed on the piston rod of the first cylinder. The second slider 350 covers the second slide rail 340 and slides in cooperation with it. Thus, through the mutual constraint of the second slide rail 340 and the second slider 350, the lifting and lowering path of the n-shaped connecting frame 330 can be limited, reducing the shaking of the n-shaped connecting frame 330 during the lifting and lowering process. At the same time, the relative displacement of the roller 500 with the diaphragm in the horizontal direction is reduced, so that the roller 500 can fully cover the diaphragm.

[0042] Please combine Figures 1-4 as well as Figure 7The horizontal movement module 400 includes a second cylinder 410 located on the module adapter plate 210 facing away from the second lifting module 300 and fixedly connected to the adapter plate 230; and a second solenoid valve group disposed on the communication pipeline between the second cylinder 410 and an external pneumatic device and electrically connected to the main controller. The second cylinder 410 is arranged along the glass sheet lamination direction, and the piston rod of the second cylinder 410 forms a horizontally moving part. Further, the second solenoid valve group includes a second intake valve disposed on the intake pipeline of the second cylinder 410 and a second exhaust valve disposed on the exhaust pipeline of the second cylinder 410. The main controller controls the intake and exhaust of the second cylinder 410 by controlling the opening and closing of the second intake valve and the second exhaust valve, thereby achieving lifting control of the piston rod of the second cylinder 410. The piston rod of the second cylinder 410 extends along the glass sheet lamination direction to drive the bracket 800 and the second suction plate 700 closer to or further away from the first suction plate 600. To improve the stability of the movement of the support 800, the upper surface of the cylinder of the second cylinder 410 is provided with a third slide rail 420 extending along the direction of the glass sheet film application. A third slider 430 is fixed on the piston rod of the second cylinder 410. The third slider 430 covers the third slide rail 420 and slides in cooperation with the third slide rail 420. In this way, the movement path of the support can be limited by the mutual constraint between the third slide rail 420 and the third slider 430, so that the second suction plate is always aligned with the first suction plate in its width direction, thereby ensuring the stability of the adsorption of the film 10 by the first and second suction plates and the flatness of the film.

[0043] The bracket 800 includes a first adapter plate 810 fixedly connected to the piston rod of the second cylinder 410, and two second adapter plates 820 oppositely disposed on both sides of the first suction plate 600 and fixedly connected to the two opposite sides of the first adapter plate 810. The second adapter plates 820 extend along the glass film application direction, and the second suction plate 700 is located between the two second adapter plates 820 and fixedly connected to them. Alternatively, the bracket 800 can be understood as having a U-shaped structure, with the width of the first adapter plate 810 greater than the width of the first suction plate 600, so that the two second adapter plates 820 are located on both sides of the first suction plate 600, thus avoiding interference between the bracket 800 and the first suction plate 600.

[0044] Please combine Figures 1-5The first suction plate 600 has several first suction holes 610 arranged in a square array. A groove 620 is formed on the upper surface of the first suction plate 600. A cover plate 630 for sealing the groove 620 is fixed to the upper surface of the first suction plate 600. An annular vacuum gasket 640 is provided between the cover plate 630 and the first suction plate 600 to prevent air leakage at the connection between the cover plate 630 and the first suction plate 600. An air passage communicating with the groove 620 is formed on the upper surface of the cover plate 630, and a first connector 650 communicating with an external air pressure device is provided at this air passage. In this design, since the first suction plate 600 is used to adsorb the main body of the membrane, and the second suction plate 700 is used to adsorb the edge of the membrane, the adsorption plane of the first membrane and the adsorption plane of the second membrane are of equal width. The length of the adsorption plane of the first membrane is N times the length of the adsorption plane of the second membrane, where N is an integer greater than or equal to 10. Of course, depending on the size of the roller 500, N can also be an integer less than 10, which will not be elaborated here. Please refer to... Figure 6 The second suction plate 700 has a plurality of second suction holes 710 arranged in a square array. The second suction plate 700 has an air groove that communicates with each of the second suction holes 710. The side of the second suction plate 700 has an air hole 720 that communicates with the air groove. A second connector 730 that communicates with an external air pressure device is fixed at the air hole 720.

[0045] In addition, the glass film application mechanism also includes a pressure regulating valve 900 fixed on the module adapter plate 210 and located between two ribs 220. The pressure regulating valve 900 is arranged on the connecting pipe between the first suction plate 600 and the external air pressure device, and the pressure regulating valve 900 is electrically connected to the main controller. In this embodiment, the air inlet and outlet of the pressure regulating valve 900 are respectively connected to the connecting pipe between the first suction plate 600 and the external air pressure device. The flow rate in the regulating valve or the opening degree of the regulating valve can be controlled by the main controller to control the air pressure at the adsorption plane of the first film, thereby controlling the adsorption force of the first suction plate 600 on the film.

[0046] Roller 500 is used to provide the extrusion force during the film lamination process, so that the film is firmly attached to the glass surface. In this solution, the shape of roller 500 is adapted to the shape of the glass to be laminated. When the glass to be laminated is flat glass, the circumferential side of roller 500 is cylindrical; when the glass to be laminated is curved glass, the circumferential side of roller 500 is a non-cylindrical curved surface.
