Description

Technical Field

[0001] The present application relates to the field of mobile phone screen production technology, and in particular to a multifunctional platform for a copper foil attaching machine. Background Art

[0002] In the production process of mobile phone screens, in order to shield electromagnetic, copper foil tape will be attached to the end of the FPC cable of the mobile phone screen, and a PET film will be set on the surface of the copper foil tape. The copper foil attachment process is attachment-pressure holding-film tearing, that is, after the copper foil tape is attached, pressure will be held first to make the copper foil tape and the mobile phone screen cable fit completely, and then the PET film will be torn off.

[0003] A copper foil attaching machine is disclosed in the related art, which mainly includes a machine, multiple manipulators, an attaching platform, a pressure-maintaining platform and a film-tearing platform, wherein the manipulators, the attaching platform, the pressure-maintaining platform and the film-tearing platform are independently arranged on the machine, and the multiple manipulators correspond to the attaching platform, the pressure-maintaining platform and the film-tearing platform respectively. A material conveyor belt that circulates between the attaching platform, the pressure-maintaining platform and the film-tearing platform is arranged on the machine, and the manipulator is matched with the material conveyor belt to make the material flow on the corresponding platform to carry out the corresponding process. However, the setting of the material conveyor belt not only makes the copper foil attaching machine occupy a large space, but also increases the material circulation time between multiple platforms. Summary of the invention

[0004] In order to reduce the space occupied by the copper foil attaching machine and reduce the time for materials to flow between multiple platforms, the present application provides a multifunctional platform for the copper foil attaching machine.

[0005] The multifunctional platform for a copper foil attaching machine provided in this application adopts the following technical solution:

[0006] A multifunctional platform for a copper foil attaching machine comprises a base plate, a plurality of overhead rods, an overhead plate, a horizontal moving device, a lifting device and a transfer frame; the two ends of the overhead rods are respectively connected to the base plate and the overhead plate, an installation gap is left between the base plate and the overhead plate, and a pressure holding area and a film tearing area are arranged on the board surface of the overhead plate facing away from the base plate; the horizontal moving device and the lifting device are both located in the installation gap; the lifting device is connected to the horizontal moving device; the horizontal moving device is used to drive the lifting device to and from the pressure holding area and the film tearing area; a moving groove is provided through the board surface of the overhead plate, and the moving groove is extended along the moving direction of the horizontal moving device; the moving groove is for the transfer frame to pass through, and one end of the moving groove passes through the side wall of the overhead plate; the transfer frame is installed on the lifting device, and the lifting device drives the transfer frame to rise and fall, and the transfer frame is used to support materials in the pressure holding area and the film tearing area.

[0007] By adopting the above technical scheme, the horizontal moving device is started to drive the lifting device and the transfer frame to move horizontally. After the transfer frame moves to the specified position, the lifting device is started, and the transfer frame supports the materials of the previous process and the materials in the pressure holding area. The horizontal moving device is started again to drive the lifting device and the transfer frame to move horizontally in the opposite direction, so that the materials of the previous process are transferred to the top of the pressure holding area, and the materials in the pressure holding area are transferred to the top of the film tearing area. Then the lifting device drives the transfer frame to descend, so that the materials are against the surface of the overhead plate. In this way, materials flow into both the pressure holding area and the film tearing area, so that the corresponding robot arm of the copper foil attaching machine can perform corresponding operations on the materials in the pressure holding area and the film tearing area, and at the same time transfer the materials in the film tearing area. Based on this, the present application provides a multifunctional platform for a copper foil attaching machine. Compared with the current multi-platform arrangement of copper foil attaching machines and the way materials flow between multiple platforms, the installation gap between the bottom plate and the overhead plate is utilized to realize the vertical space utilization, and a horizontal moving device and a lifting device are used to utilize the transfer rack to transfer materials between the front process, the pressure holding area and the film tearing area. In this way, while realizing the material transfer, the pressure holding platform and the film tearing platform of the current copper foil attaching machine are integrated into one platform, shortening the distance between the pressure holding platform and the film tearing platform, thereby reducing the space occupied by the copper foil attaching machine and reducing the time for materials to flow between multiple platforms.

[0008] Optionally, the overhead plate is provided with a negative pressure part at the film tearing area, and the negative pressure part is used to adsorb the material to the board surface of the overhead plate; the transfer rack is provided with a material suction cup with an external negative pressure; the overhead plate is provided with an air blowing part at the film tearing area, and the air blowing part is externally connected to a compressed air device, and the air blowing part is used to guide compressed air to blow the flexible part of the material.

[0009] By adopting the above technical solution, when the transfer rack is used to support and transfer the material, the negative pressure of the material suction cup is used to temporarily fix the position of the material on the transfer rack. For example, when transferring a mobile phone screen with an FPC cable installed, the flexible FPC cable will bend under the influence of gravity when the mobile phone screen is lifted. After the mobile phone screen is placed on the overhead board, the bent FPC cable will spread on the board surface of the overhead board, disconnect the negative pressure of the material suction cup, and then use the negative pressure part to adsorb the material to fix it on the board surface of the overhead board, so as to reduce the displacement of the material position when the subsequent process is unfolded, such as the pressure holding process or the film tearing process. When the FPC cable is converted from a bent state to a spread state, the edge of the FPC cable or the structure on it is easy to rub against the board surface of the overhead board or to collide with the negative pressure part, which will hinder the spreading of the FPC in the bent state, causing the FPC in the bent state to arch and generate a gap between it and the negative pressure part, and it is easy for the negative pressure part to have difficulty adsorbing the FPC cable in the bent state. The air blowing part blows air toward the bent FPC cable to adjust the bent FPC cable and spread it, so that the spread FPC cable contacts the board surface of the overhead board, thereby improving the contact success rate between the negative pressure part and the FPC cable and improving the problem that the bent FPC cable is difficult to be adsorbed by the negative pressure part.

[0010] Optionally, the negative pressure part includes a vacuum suction cup; a placement groove is opened on the board surface of the overhead board; the vacuum suction cup is located in the placement groove and is externally connected to a negative pressure device; the vacuum suction cup is for material to abut.

[0011] By adopting the above technical solution, the vacuum suction cup adsorbs the material, such as the FPC cable of the mobile phone screen, to reduce the risk of the mobile phone screen moving during the film tearing operation, thereby reducing the risk of the material escaping from the negative pressure part and improving the connection stability between the material and the overhead plate.

[0012] Optionally, the board surface of the overhead plate is provided with an air blowing groove, the air blowing part is located in the air blowing groove, and the overhead plate is provided with a flow regulating mechanism in the air blowing groove. When the transfer rack is raised or lowered, the flow regulating mechanism regulates the gas flow rate blown toward the material through the air blowing part.

[0013] By adopting the above technical solution, when the lifting device drives the transfer rack to descend and the height of the material is in a changing process, the blowing part blows air to the flexible part of the material all the time, so that the flexible part of the material is in a state of being supported by the airflow, for example, the FPC cable of the mobile phone screen is spread in the air. And the flow regulating mechanism changes the gas flow rate of the blowing part blowing to the material as the transfer rack rises and falls, so that the material corresponds to different gas flow rates at different heights, and improves the problem of the material detaching from the transfer rack when the gas flow rate of the blowing part blowing to the material is large, so that when the material is at different heights, the airflow of the blowing part blowing to the material can improve the bending of the flexible part of the material, and take into account the connection stability between the material and the transfer rack; when the material is placed on the board surface of the overhead board, the risk of the flexible part of the material being stuck in the groove on the overhead board is reduced, the problem of the flexible part of the material being arched on the overhead board is improved, the problem of the mobile phone screen FPC cable being damaged due to bending is improved, and the problem of the negative pressure part being unable to adsorb the material is improved.

[0014] Optionally, the flow regulating mechanism includes an elastic ring, a plurality of movable sheets, an elastic band and an elastic circular ring air bag, the blowing part is a blowing hole opened at the bottom of the blowing groove; the elastic ring is installed on the overhead plate at the bottom of the blowing groove and is coaxially arranged with the blowing hole; a plurality of the movable sheets are installed on the elastic ring, and the plurality of movable sheets are arranged at intervals along the circumference of the elastic ring; the elastic band is used to connect two adjacent movable sheets and block the gap between two adjacent movable sheets; the plurality of movable sheets and the elastic band form an air cylinder with openings at both ends; the elastic circular ring air bag is movably connected to the inner wall of the air cylinder and is coaxially arranged with the elastic ring, and the elastic circular ring air bag is externally connected to an inflation device.

[0015] By adopting the above technical solution, when the lifting device drives the transfer rack to lift, the inflation device connected to the elastic annular air bag and the compressed air device connected to the blowing hole are started. Since the movable sheet is installed on the elastic ring and the elastic band connects two adjacent movable sheets, as the elastic annular air bag is inflated and expanded, the elastic ring and the elastic band will be elastically deformed, and the opening of the air cylinder will gradually expand, achieving the effect of changing the gas flow rate blown to the material through the blowing part. When the material is against the board surface of the overhead board, the inflation device and the compressed air device are turned off, and the material can be fixed to the board surface of the overhead board through the negative pressure part. At the same time, in the process before the elastic ring and the elastic band restore the elastic deformation, the multiple movable sheets squeeze the expanded elastic annular air bag, so that the gas in the elastic annular air bag is discharged to the inflation device or the outside world, so that the opening of the air cylinder is restored to the state before the expansion, waiting for the next time the material is placed on the board surface of the overhead board. Through the expansion and contraction of the elastic circular ring air bag and the combination of multiple movable plates, the dynamic change of the size of the air cylinder opening is achieved during the elastic deformation of the elastic ring and the elastic band. The elastic circular ring air bag is located on the inner wall of the air cylinder, so that the size of the air cylinder opening is further reduced, thereby increasing the adjustment range of the flow regulating mechanism for regulating the gas flow blown to the material through the blowing hole.

[0016] Optionally, exhaust holes are provided on the surface of the elastic circular ring air bag.

[0017] By adopting the above technical solution and introducing the exhaust hole, the shrinkage efficiency of the expanded elastic annular air bag is improved, while the response speed and change efficiency of the flow regulating mechanism are improved.

[0018] Optionally, the flow regulating mechanism includes a servo motor and a connecting wire; the servo motor is installed on the overhead plate; the blowing part is an elastic blowing pipe, and the elastic blowing pipe is externally connected to a compressed air device; the connecting wire is wound around the outer peripheral side of the elastic blowing pipe; one end of the connecting wire is connected to the inner wall of the overhead plate located at the blowing groove, and the other end is connected to the side wall of the servo motor shaft.

[0019] By adopting the above technical solution, when the lifting device drives the transfer rack to lift, the servo motor and the compressed air device connected to the elastic blowing pipe are started, the shaft of the servo motor rotates, and the connecting wire wound around the shaft will be loosened. The connecting wire is located at the winding part of the elastic blowing pipe. Under the elastic force of the elastic blowing pipe, the mouth of the elastic blowing pipe will change from small to large, thereby achieving the effect of adjusting the gas flow rate of the blowing part to the material. Due to the high control accuracy of the servo motor, the deformation of the mouth of the elastic blowing pipe is changed through the servo motor and the connecting wire to accurately control the gas flow rate of the blowing part to the material, improve the adjustment range of the flow regulating mechanism to adjust the gas flow rate blown to the material through the blowing hole, and at the same time improve the adjustment accuracy of the flow regulating mechanism.

[0020] Optionally, a limit plate is provided on the inner wall of the overhead plate located at the blowing groove; a limit hole is formed through the plate surface of the limit plate; and the limit hole is for the elastic blowing pipe to pass through.

[0021] By adopting the above technical solution and introducing the limit plate, through the limit hole, when the elastic blowing pipe is tightened or relaxed at the connecting line, the risk of excessive deviation of the position of the pipe mouth of the elastic blowing pipe causing the air flow direction to deviate is reduced.

[0022] Optionally, a movable block is detachably connected to the overhead plate; the placement groove passes through the board surface of the overhead plate; the vacuum suction cup is installed on the movable block; and the placement groove is extended along the movement direction of the horizontal moving device.

[0023] By adopting the above technical solution, the vacuum suction cup is connected to the movable block, and when the movable block is subsequently separated from the overhead plate, the vacuum suction cup can be replaced or the position of the vacuum suction cup can be changed, so that different types of vacuum suction cups correspond to different types of materials, thereby improving the adaptability of the vacuum suction cup.

[0024] Optionally, a blowing piece is provided on the transfer rack, and the blowing piece is externally connected to a compressed air device, and the blowing piece is used to guide the compressed air to blow toward the board surface of the overhead board.

[0025] By adopting the above technical scheme, since the pressure holding area and the film tearing area are both located on the board surface of the overhead board, the transfer rack can be horizontally moved by the horizontal moving device and the lifting and lowering of the lifting device, thereby cleaning the impurities on the surface of the pressure holding area and the film tearing area at the same time, thereby reducing the risk of impurities damaging the material when the material is placed in the pressure holding area or the film tearing area. In this way, the transfer rack not only realizes the effect of supporting the material, but also realizes the effect of cleaning the pressure holding area and the film tearing area at the same time in combination with the blowing parts.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Compared with the current multi-platform arrangement of copper foil attaching machines and the material flow between multiple platforms, the installation gap between the bottom plate and the overhead plate is used to realize the vertical space utilization, and the horizontal moving device and the lifting device are matched to use the transfer rack to flow the materials between the front process, the pressure holding area and the film tearing area. In this way, while realizing the material transfer, the pressure holding platform and the film tearing platform of the current copper foil attaching machine are integrated into one platform, shortening the distance between the pressure holding platform and the film tearing platform, which not only reduces the space occupied by the copper foil attaching machine, but also reduces the material flow time between multiple platforms;

[0028] 2. The compressed air is guided to the flexible part of the material through the air blowing part to adjust the bending state of the flexible part of the material so that the flexible part of the material being spread contacts the surface of the overhead plate, thereby increasing the contact success rate between the negative pressure part and the flexible part of the material and improving the problem that the flexible part of the material in the bent state is difficult to be adsorbed by the negative pressure part;

[0029] 3. Through the flow regulating mechanism, when the material is at different heights, the air flow rate blown by the blowing part to the material is changed, so that the flexible part of the material is spread in the air, thereby reducing the risk of the bent flexible part of the material getting stuck in the groove on the overhead board when the material is placed on the board surface of the overhead board, improving the problem of the flexible part of the material being arched on the overhead board, improving the problem of the flexible part of the material being damaged due to bending, and at the same time improving the problem of the negative pressure part being unable to adsorb the material.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-8 This application is described in further detail.

[0040] In the production process of mobile phone screens, in order to shield electromagnetic waves, copper foil tape is attached to the end of the FPC cable of the mobile phone screen, and a PET film is provided on the surface of the copper foil tape. The process of copper foil attachment is attachment-pressure holding-film tearing, and a copper foil attaching machine is currently used for copper foil attachment. The copper foil attaching machine includes a machine, multiple platforms, multiple manipulators and a material conveyor belt, wherein each platform corresponds to a corresponding process, and each manipulator corresponds to each platform to carry out the corresponding process. The material conveyor belt flows between multiple platforms, which not only makes the copper foil attaching machine occupy a large space, but also increases the material circulation time between multiple platforms.

[0041] The embodiment of the present application discloses a multifunctional platform for a copper foil attaching machine, which aims to reduce the space occupied by the copper foil attaching machine and reduce the time for materials to flow between multiple platforms.

[0042] Example 1

[0043] Reference Figure 1 and Figure 2 A multifunctional platform for a copper foil attaching machine includes a base plate 1, a plurality of overhead rods 2, an overhead plate 3, a horizontal moving device 4, a lifting device 5 and a transfer frame 6, wherein the base plate 1 is installed on the machine platform of the copper foil attaching machine. The two ends of the overhead rods 2 are respectively fixed to the board surface of the base plate 1 and the board surface of the overhead plate 3, and an installation gap is left between the base plate 1 and the overhead plate 3. The board surface of the overhead plate 3 facing away from the base plate 1 is provided with a pressure holding area 31 and a film tearing area 32. The board surface of the overhead plate 3 is penetrated by a moving groove 33, and the moving groove 33 is extended along the movement direction of the horizontal moving device 4. The moving groove 33 is for the transfer frame 6 to pass through. One end of the moving groove 33 passes through the side wall of the overhead plate 3, and the moving groove 33 simultaneously connects the pressure holding area 31 and the film tearing area 32. It is worth noting that the pressure holding area 31 and the film tearing area 32 correspond to multiple manipulators on the copper foil attaching machine.

[0044] Also refer to Figure 3, the board surface of the overhead board 3 located in the holding area 31 and the film tearing area 32 is provided with a negative pressure part 7, and the negative pressure part 7 is used to adsorb materials to the board surface of the overhead board 3, and the negative pressure part 7 is externally connected to a negative pressure device. It should be noted that the negative pressure part 7 of the holding area 31 is defined as the first adsorption part, and the negative pressure part 7 of the film tearing area 32 is defined as the second adsorption part. The first adsorption part is a vacuum groove opened on the board surface of the overhead board 3, and the vacuum groove is an annular structure, and a vacuum hole is opened at the bottom of the vacuum groove. The second adsorption part includes a vacuum suction cup, and a movable block 8 is detachably connected to the overhead board 3, and the vacuum suction cup is fixed on the movable block 8. A placement groove 34 is opened through the board surface of the overhead board 3, and the placement groove is extended along the movement direction of the horizontal moving device 4. The vacuum suction cup is located in the placement groove, and the vacuum suction cup is abutted for materials (such as the FPC cable of the mobile phone screen). The significance of setting the negative pressure parts 7 of the pressure holding area 31 and the film tearing area 32 to different structures is that, since the pressure holding process is to press the material, it is necessary to avoid opening grooves under the material (such as the FPC cable of the mobile phone screen) to reduce the risk of material damage. In the film tearing process, the robot needs to tear off the film adhered to the material, and the high suction force of the vacuum suction cup is used to reduce the risk of material movement in the negative pressure area during the film tearing process.

[0045] In one embodiment, the first adsorption portion and the second adsorption portion have the same structure, that is, both are a combination structure of a vacuum groove and a vacuum hole.

[0046] It is worth noting that the detachable connection between the movable block 8 and the overhead plate 3 can be a bolt connection. The board surface of the overhead plate 3 is provided with a waist-shaped stepped hole, which is extended along the extension direction of the placement groove. The waist-shaped stepped hole is for the bolt to pass through, and can also be magnetically fixed, etc., so as to facilitate the subsequent adjustment of the position of the vacuum suction cup to adapt to different types of materials.

[0047] The horizontal moving device 4 and the lifting device 5 are both located in the installation gap, the horizontal moving device 4 is fixed on the bottom plate 1, and the lifting device 5 is connected to the horizontal moving device 4. The horizontal moving device 4 is used to drive the lifting device 5 and the transfer frame 6 to and from the pressure holding area 31 and the film tearing area 32. It should be noted that the horizontal moving device 4 can be a cylinder, a screw slider mechanism, or a belt transmission mechanism, and the present application is not limited thereto. Similarly, the lifting device 5 can be a cylinder, a screw lifting mechanism, etc., and the present application is not limited thereto.

[0048] The transfer rack 6 is installed on the lifting device 5, and the lifting device 5 drives the transfer rack 6 to rise and fall. A material suction cup 61 is fixed on the transfer rack 6. The material suction cup 61 is externally connected to a negative pressure device and is provided for material to abut. The transfer rack 6 is used to support the materials in the pressure holding area 31 and the film tearing area 32.

[0049] The implementation principle of Example 1 is as follows: start the horizontal moving device 4 to drive the lifting device 5 and the transfer rack 6 to move horizontally. After the transfer rack 6 moves to the specified position, start the lifting device 5, and the transfer rack 6 supports the materials of the previous process (such as the attachment process) and the materials in the pressure holding area 31. Start the horizontal moving device 4 again to drive the lifting device 5 and the transfer rack 6 to move horizontally in the opposite direction, so that the materials of the previous process are transferred to the top of the pressure holding area 31, and the materials in the pressure holding area 31 are transferred to the top of the film tearing area 32. Then the lifting device 5 drives the transfer rack 6 to descend, so that the materials are against the board surface of the overhead plate 3. In this way, materials flow into both the pressure holding area 31 and the film tearing area 32, so that the corresponding manipulator of the copper foil attaching machine can perform corresponding operations on the materials in the pressure holding area 31 and the film tearing area 32, and at the same time transfer the materials in the film tearing area 32. By utilizing the installation gap between the bottom plate 1 and the overhead plate 3, the space utilization in the vertical direction is realized, and the horizontal moving device 4 and the lifting device 5 are matched, and the transfer rack 6 is used to circulate the materials between the front process, the pressure holding area 31 and the film tearing area 32, so that the traditional material conveyor belt used for circulating materials is placed under the platform, reducing the space occupied by the copper foil attaching machine, and integrating the traditional pressure holding platform and the film tearing platform into the same platform. With the manipulator of the copper foil attaching machine, it has both the functions of the pressure holding platform and the film tearing platform, shortens the distance between the pressure holding platform and the film tearing platform, thereby reducing the time for materials to flow between multiple platforms.

[0050] Example 2

[0051] Continue to refer to Figure 4 , the difference between this embodiment and embodiment 1 is that a blowing piece 62 is obliquely arranged on the transfer rack 6, and the blowing piece 62 is externally connected to a compressed air device. The blowing piece 62 is used to guide the compressed air to blow toward the board surface of the overhead board 3. The blowing piece 62 can be an air pipe, or a hole, etc., and the present application is not limited thereto. Since the pressure holding area 31 and the film tearing area 32 are both located on the board surface of the overhead board 3, when the transfer rack 6 is horizontally moved by the horizontal moving device 4 and the lifting device 5 is lifted and lowered, the impurities on the surface of the pressure holding area 31 and the film tearing area 32 can be cleaned at the same time, thereby reducing the risk of impurities damaging the material when the material is placed in the pressure holding area 31 or the film tearing area 32 (such as the crushing of the mobile phone screen). In this way, the transfer rack 6 not only achieves the effect of supporting the material, but also achieves the effect of cleaning the pressure holding area 31 and the film tearing area 32 at the same time with the blowing piece 62.

[0052] Example 3

[0053] Reference Figure 5 and Figure 6The difference between this embodiment and embodiment 1 is that the overhead plate 3 is provided with a blowing portion 9 at the position of the film tearing area 32, and the board surface of the overhead plate 3 is penetrated by a blowing groove 35 for accommodating the blowing portion 9. It can be understood that the surface of the movable block 8 is the bottom of the blowing groove 35, and the blowing portion 9 is located at the bottom of the blowing groove 35. In this embodiment, the blowing portion 9 is a blowing hole. The blowing portion 9 is externally connected to a compressed air device, and the blowing portion 9 is used to guide compressed air to blow the flexible part of the material (such as the FPC cable of the mobile phone screen). In this way, the compressed air is guided to the flexible part of the material by the blowing portion 9, and the bending state of the flexible part of the material is adjusted, so that the spread flexible part of the material contacts with the board surface of the overhead plate 3, thereby improving the contact success rate between the negative pressure portion 7 and the flexible part of the material, and improving the problem that the flexible part of the material in the bent state is difficult to be adsorbed by the negative pressure portion 7.

[0054] The movable block 8 is provided with a flow regulating mechanism 10. When the transfer rack 6 is raised or lowered, the flow regulating mechanism 10 regulates the gas flow rate blown to the material through the blowing part 9. It can be understood that when the material is placed on the board surface of the overhead board 3 from top to bottom, the air pressure blown to the soft part of the material is weakened from strong through the flow regulating mechanism 10, so that the soft part of the material is in a spreading state during the lifting process, reducing the risk of the bent flexible part of the material being stuck in the groove on the overhead board 3, and improving the problem of the flexible part of the material being arched and damaged on the overhead board 3.

[0055] The flow regulating mechanism 10 comprises an elastic ring 101, a plurality of movable sheets 102, an elastic band 103 and an elastic circular air bag 104, wherein the elastic ring 101 is fixed to the surface of the movable block 8 and is coaxially arranged with the blowing hole. The plurality of movable sheets 102 are all fixed to the side wall of the elastic ring 101 and have a gap between them and the surface of the movable block 8, and the plurality of movable sheets 102 are arranged at intervals along the circumference of the elastic ring 101. The elastic band 103 is used to connect two adjacent movable sheets 102 and block the gap between the two adjacent movable sheets 102, and the plurality of movable sheets 102 and the elastic band 103 form an air cylinder with openings at both ends. The elastic annular air bag 104 is located in the air cylinder and is connected to the surface of the movable sheet 102. An exhaust hole 1041 is provided on the surface of the elastic annular air bag 104. The elastic annular air bag 104 is coaxially arranged with the elastic ring 101. The elastic annular air bag 104 is externally connected to an inflatable device. It should be noted that the inflatable device can set the opening and closing time through a copper foil attaching machine, and can also be electrically connected to the lifting device 5 to open and close the inflatable device when the lifting device 5 has a lifting action.

[0056] When the lifting device 5 drives the transfer rack 6 to rise and fall, the inflation device connected to the elastic annular air bag 104 and the compressed air device connected to the blowing hole are started. Since the movable sheet 102 is installed on the elastic ring 101 and the elastic belt 103 connects two adjacent movable sheets 102, as the elastic annular air bag 104 is inflated and expanded, the elastic ring 101 and the elastic belt 103 will be elastically deformed, and the opening of the air cylinder will gradually expand, achieving the effect of changing the gas flow rate blown to the material through the blowing part 9. When the material is against the board surface of the overhead board 3, the inflation device and the compressed air device are turned off, and the material can be fixed on the board surface of the overhead board 3 through the negative pressure part 7. At the same time, in the process before the elastic ring 101 and the elastic belt 103 restore the elastic deformation, the multiple movable sheets 102 squeeze the expanded elastic annular air bag 104, and the gas in the elastic annular air bag 104 is discharged to the outside through the exhaust hole 1041, so that the opening of the air cylinder is restored to the state before the expansion, waiting for the next material to be placed on the board surface of the overhead board 3.

[0057] In one embodiment, the overhead plate 3 is also provided with a blowing portion 9 and a flow regulating mechanism 10 at the position of the pressure maintaining area 31 .

[0058] The implementation principle of Example 3 is: through the blowing part 9 and the flow regulating mechanism 10, in the process of transferring materials on the transfer rack 6, the effect of the soft part of the material spreading in the air is achieved, thereby reducing the risk of the soft part of the material being damaged by arching when the material is placed on the board surface of the overhead plate 3, and improving the problem that the flexible part of the material is difficult to be adsorbed by the negative pressure part 7 due to the arching. In this way, the production yield of the copper foil attaching machine is improved, and the problem of frequent alarms of the copper foil attaching machine due to the inability to vacuum adsorb the material is improved.

[0059] Example 4

[0060] Reference Figure 7 and Figure 8 The difference between this embodiment and the embodiment 3 is that the structures of the blowing part 9 and the flow regulating mechanism 10 are different. The blowing part 9 is an elastic blowing pipe, and a limit plate 36 is fixed on the inner wall of the overhead plate 3 located at the blowing groove 35. The plate surface of the limit plate 36 is penetrated by a limit hole 361, and the limit hole 361 is for the elastic blowing pipe to pass through.

[0061] The flow regulating mechanism 10 includes a servo motor 105 and a connecting wire 106. The servo motor 105 is mounted on the overhead plate 3, and the rotating shaft of the servo motor 105 is located in the air blowing groove 35. The connecting wire 106 is wound around the outer peripheral side of the elastic air blowing pipe passing through the limiting hole 351. One end of the connecting wire 106 is connected to the inner wall of the overhead plate 3 located in the air blowing groove 35, and the other end is connected to the side wall of the rotating shaft of the servo motor 105.

[0062] When the lifting device 5 drives the transfer rack 6 to lift, the servo motor 105 and the compressed air device connected to the elastic blowing pipe are started, the shaft of the servo motor 105 rotates, and the connecting wire 106 wound around the shaft will be loosened. The connecting wire 106 is located at the winding part of the elastic blowing pipe. Under the elastic force of the elastic blowing pipe, the mouth of the elastic blowing pipe will change from small to large, thereby achieving the effect of adjusting the gas flow rate of the blowing part 9 to the material. Due to the high control accuracy of the servo motor 105, the deformation of the mouth of the elastic blowing pipe is changed through the servo motor 105 and the connecting wire 106 to accurately control the gas flow rate of the blowing part 9 to the material, improve the adjustment range of the flow regulating mechanism 10 to adjust the gas flow rate blown to the material through the blowing hole, and at the same time improve the adjustment accuracy of the flow regulating mechanism 10.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
