Detailed implementation manners

[0026] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Referring to Figures 1 to 3 As shown, the present invention also provides a medium-sized fully automatic tape pasting machine, including a frame 21 and a housing 20 arranged on the frame 21. A carrying platform 8 for placing the FPC to be pasted, a loading and unloading assembly, a stripping knife assembly, and a suction head assembly are arranged on the frame 21.

[0029] The loading and unloading assembly is used for loading the FPC to be pasted and unloading the FPC with the tape pasted. The stripping knife assembly is used for placing the tape coil to be bonded and separating it to obtain the tape to be bonded. The suction head assembly is used for adsorbing the tape to be bonded and bonding it on the FPC to be pasted.

[0030] Referring to Figure 4As shown in the figure, for the convenience of installation and to ensure the reliability of the operation of the entire device, the stage 8 is installed on the frame 21 through the platform 4. A Y-axis guide rail 23 and a Y-axis linear motor 22 are provided between the platform 4 and the stage 8, enabling the stage 8 to drive the FPC to be pasted placed thereon to move longitudinally in the Y-axis direction on the platform 4, so that it can move to the loading and unloading positions of the FPC to be pasted, and can also move to the pasting position.

[0031] Furthermore, a blower 24 is adopted and connected to the stage 8 through a corrugated pipe passing through the platform 4, that is, the stage 8 has a vacuum adsorption function, firmly adsorbing the FPC to be pasted placed thereon on the stage 8 and sucking the FPC to be pasted flat. Similarly, the stage 8 also has a heating device, enabling it to have a heating function for heating the FPC to be pasted placed thereon.

[0032] Furthermore, a left material image system 14 and a right material image system 15 are symmetrically arranged on both sides of the stage 8 on the platform 4 for photographing and positioning the adhesive tape to be pasted.

[0033] Refer to Figure 5 As shown in the figure, the loading and unloading assembly includes a loading tray 10, an unloading tray 6, an unloading manipulator 5, and a loading manipulator 11. The loading tray 10 is arranged on one side of the stage 8, and the right separator paper tray 7 is arranged on the other side opposite to the stage 8. The unloading manipulator 5 and the loading manipulator 11 are arranged on the platform 4 and above the stage 8. A guide rail and a synchronous belt are provided between the unloading manipulator 5 and the loading manipulator 11 and the platform 4, enabling them to translate in the X-axis direction. In this way, the FPC to be pasted can be conveniently adsorbed from the loading tray 10 and placed on the stage 8, and the FPC with the adhesive tape pasted can also be adsorbed and placed on the unloading tray 6, thus completing the loading and unloading.

[0034] Furthermore, the loading and unloading assembly further includes a left separator paper tray 9 and a right separator paper tray 7 for placing separator paper. The left separator paper tray 9 is arranged in parallel with the loading tray 10, and the right separator paper tray 7 is arranged in parallel with the unloading tray 6.

[0035] During specific feeding, the feeding manipulator 11 moves above the feeding tray 10, picks up a piece of FPC to be pasted, drives the FPC to be pasted to move and places it on the carrier table 8. After placing it, the blower 24 and the heating function are started to firmly and flatly adsorb the FPC to be pasted on the carrier table 8 and heat the FPC to be pasted. At the same time, the carrier table 8 drives the adsorbed FPC to be pasted to run to the pasting position. At this time, the feeding manipulator 11 moves back above the feeding tray assembly 10 along the X-axis and picks up the next FPC to wait. During discharging, the discharging manipulator 5 moves above the carrier table 8, the discharging manipulator 5 descends and turns on the vacuum adsorption, sucks up the FPC with the sticker pasted, rises to the uppermost end, and drives the FPC with the sticker pasted to move above the discharging tray 6, descends and stops the vacuum adsorption, and the FPC is placed in the discharging tray 6.

[0036] Refer to Figure 6 As shown, the stripping knife assembly is located below the loading and unloading assembly. In order to ensure reliable operation and improve the working efficiency of the equipment in the embodiment of the present invention, two sets of stripping knife assemblies, namely the left stripping knife assembly 18 and the right stripping knife assembly 16, are symmetrically arranged on both sides of the platform 4 and are respectively located below the feeding tray 10 and the discharging tray 6.

[0037] The left stripping knife assembly 18 and the right stripping knife assembly 16 have the same structure. Both include a side plate 161, and a feeding shaft 25, a film winding-up shaft 30 and a material winding-up shaft 29 are sequentially and parallelly arranged on the side plate 161. A stripping knife 26 for fixing the receiving table 27 is also arranged on the side plate 161. The stripping knife 26 is located above the material winding-up shaft 29 and is connected to the side plate 161 through a guide rail and a lead screw, so that both the stripping knife 26 and the receiving table 27 can move on the side plate 161.

[0038] Furthermore, a material pulling system 28 is also arranged on the side plate 161 and below the receiving table 27, which is used to pull the material tape during stripping to move the material pasted on the material tape to a proper position, and then press the material tape to prevent it from moving, so as to improve the stripping accuracy. The material pulling system 28 includes a first roller 281, a second roller 282, a material pulling motor 283 and a material pulling cylinder 284. The first roller 281 is connected to the material pulling motor 283 through a synchronous belt to make a rotational movement and can pull the material tape.

[0039] In the above, the second roller 282 is driven to rotate by the material pulling cylinder 284. By controlling the tightness of the fit between the first roller 281 and the second roller 282 through the material pulling cylinder 284, the clamping and opening of the two silicone rollers can be achieved. A material tape passes through between the first roller 281 and the second roller 282 and can be clamped by them. When automatically stripping, the material tape is pulled to move it to a proper position, then the material tape is pressed tightly to prevent it from moving, and its relative position with the stripping knife 26 is ensured to be unchanged, so as to improve the stripping accuracy and prevent the material from deforming. In the embodiment of the present invention, both the first roller 281 and the second roller 282 are made of silicone rollers, with simple structure and reliable operation.

[0040] Further, an electromagnetic brake 251 is installed on the loading shaft 25, which can ensure that the loading shaft 25 is locked when the stripping knife 26 strips materials through the transfer suction cup assembly, ensuring the tightness of the material tape, thereby ensuring the reliability of the equipment operation and improving the stripping accuracy.

[0041] Specifically, an operator places a roll of adhesive tape to be adhered on the loading shaft 27, and the end of the material tape of the adhesive tape passes through the gap between the stripping knife 26 and the receiving table 27, and the gap between the first roller 281 and the second roller 282 of the material pulling system 28 in sequence, and finally winds around the winding shaft 29. The upper protective film of the adhesive tape roll is wound around the upper film winding shaft 30, and the material tape is adjusted to an accurate position. By means of the material pulling cylinder 284, it can be ensured that when the stripping knife 26 moves, the material tape is always in a tightened state and its relative position does not move, thereby improving the stripping accuracy.

[0042] Further, a transfer suction cup assembly is arranged on the side plate 161 and above the receiving table 27 for adsorbing the adhesive tape when stripping the adhesive tape roll. The transfer suction cup assembly can move up and down along its own guide rail and is connected to a blower to realize the vacuum adsorption function and the vacuum breaking function. In the embodiment of the present invention, a right transfer suction cup assembly 17 is arranged in the right stripping knife assembly 16, and a left transfer suction cup assembly 19 is arranged in the left stripping knife assembly 18.

[0043] During specific automatic stripping, the material pulling system 28 operates, i.e., the first roller 281 rotates to pull the tape of the adhesive tape roll to the stripping position. The stripping knife 26 drives the receiving table 27 to move rightward, and the tape is pressed tightly through the cooperation of the second roller 282 and the first roller 281. The electromagnetic brake also locks the loading shaft 25 to ensure that the position of the tape remains stationary, and then the stripping knife 26 can strip the adhesive tape on the tape. At this time, the stripping knife 26 and the receiving table 27 move leftward to below the transfer suction cup assembly, and the position of the tape also remains unchanged. The suction cup of the transfer suction cup assembly descends to be closely above the stripping knife 26 and turns on the vacuum adsorption to adsorb the stripped adhesive tape. The stripping knife 26 and the receiving table 27 continue to move, moving the receiving table 27 directly below the suction cup in the transfer suction cup assembly. The suction cup of the transfer suction cup assembly stops the vacuum adsorption and turns on the vacuum breaking, and the receiving table 27 turns on the vacuum adsorption, and the adhesive tape will fall onto the receiving table 27.

[0044] In the embodiment of the present invention, the stripping knife assembly, through the transfer suction cup assembly and in cooperation with the material pulling system 28, can achieve precise stripping of adhesive tapes, covering films or shielding films with complex shapes. When stripping special-shaped materials with complex shapes, after being stripped by the stripping knife 26, it is difficult for the material to directly reach the receiving table 27 and still remain undeformed. Usually, deformation, wrinkles and other situations will occur, thus affecting the pasting accuracy and equipment stability. By sucking the material with the suction cup of the suction cup assembly, then translating through the stripping knife 26 and the receiving table 27, and then the transfer suction cup assembly turns on the vacuum breaking and the receiving table 27 turns on the vacuum adsorption, in this way, the receiving table 27 can firmly catch the stripped material and ensure that it remains undeformed.

[0045] Refer to Figure 7 As shown, the suction head assembly is arranged on the platform 4 through the cross beam 3. For the convenience of installation, the cross beam 3 is arranged on the platform 4 through the connecting frame 301. To improve work efficiency, the suction head assembly includes a connecting plate, a suction head Z-axis, a U-axis and a suction head. The suction head Z-axis is installed on the connecting plate and is provided with a U-axis. The U-axis is provided with a suction head capable of performing vertical and rotational movements. The suction head also has a vacuum adsorption function and a heating function for adsorbing and heating the adhesive tape (covering film, shielding film). Further, a Mark imaging system corresponding to the position of the carrier table 8 is also arranged on the U-axis for taking pictures of the FPC to be pasted.

[0046] In the embodiment of the present invention, two sets of suction head assemblies are also adopted, namely the left suction head assembly 12 and the right suction head assembly 2. A left suction head Z-axis 31 is arranged on the left connecting plate 121 of the left suction head assembly 12. A left U-axis 32 is fixed on the left suction head Z-axis 31, and a left suction head 321 is arranged on the left U-axis 32. A right suction head Z-axis 33 is arranged on the right connecting plate 211 of the right suction head assembly 2. A right U-axis 34 is fixed on the right suction head Z-axis 33, and a right suction head 341 is arranged on the right U-axis 34. A left Mark imaging system 13 and a right Mark imaging system 1 are also fixed on the left U-axis 32 and the right U-axis 34 for taking pictures of the FPC to be pasted.

[0047] In the embodiment of the present invention, both the platform 4 and the cross beam 3 are made of marble. The marble has precise structure, good stability, shock absorption performance and high hardness, and can effectively improve the accuracy and stability of the equipment.

[0048] Specifically, taking the process of the right suction head assembly 2 pasting materials as an example, the right suction head Z-axis 33 drives the right U-axis 34 to descend a certain distance. The right U-axis 34 turns on the vacuum adsorption function and the heating function, and the adhesive tape to be pasted will be sucked by the right suction head 341 and perform the next action. The right suction head assembly 2 will move along the X-axis guide rail 36 to the pasting position on the FPC to be pasted. When it moves above the right material imaging system 15, the right material imaging system 15 will take pictures and position the adhesive tape on the right suction head 341 to determine the accurate position of the adhesive tape on the right suction head 341. At this time, the right suction head assembly 2 continues to run and runs to the pasting position on the FPC. The right U-axis 34 drives the right suction head 341 to press down along the Z-axis, and at the same time closes the vacuum adsorption. After pressing for a specified time, the right U-axis 34 rises along the Z-axis, and the adhesive tape to be pasted will be pasted to the specified position of the FPC to be pasted on the stage 8.

[0049] Taking the pasting of adhesive tape as an example, the following further describes the pasting process of the pasting machine in the embodiment of the present invention. The operations and processes of pasting the cover film, shielding film, etc. are the same as those of pasting the adhesive tape. The specific process is as follows:

[0050] (1) The operator neatly places several pieces of FPC materials (i.e., FPC to be pasted) that need to be pasted with adhesive tape on the loading tray 10 and positions them. When separator paper is required, several pieces of separator paper are neatly placed on the left separator paper tray 9 and positioned.

[0051] (2) The operator places the adhesive tape roll material to be pasted on the loading shaft 25 of the peeling knife assembly, adjusts the tape to the accurate position through the material pulling system 28, and presses it tightly.

[0052] (3) After the pasting machine performs the reset operation, it starts to run automatically.

[0053] (4) The loading and unloading component starts the loading work. The loading manipulator 11 sucks a piece of FPC to be pasted and moves it to place it on the carrier 8. The carrier 8 drives the FPC to be pasted to run to the pasting position; at this time, the loading manipulator 11 returns to its original position, sucks the next piece of FPC to be pasted and waits.

[0054] (5) The left suction head component 12 moves above the FPC to be pasted, takes pictures of specific Mark points on the FPC to be pasted through the left Mark imaging system 13 and performs positioning to determine the accurate position of the FPC to be pasted on the carrier 8; meanwhile, the right suction head component 2 moves above the receiving table 27 of the right stripping knife component 16 and waits to adsorb the adhesive tape roll stock.

[0055] (6) The right stripping knife component 16 starts to work. Through the action of the material pulling system 28 and the stripping knife 26, the adhesive tape roll stock is separated to obtain the adhesive tape. The separated adhesive tape is adsorbed by the suction cups of the right transfer suction cup component 17, and the adhesive tape is placed on the receiving table 27 and then rises and returns to its original position. The stripping knife 26 and the receiving table 27 continue to move, driving the adhesive tape to move below the right suction head component 2.

[0056] (7) The right suction head component 2 starts to work. The U-axis, suction head Z-axis and suction in the right suction head component 2 drive the right suction head 341 to move. The right suction head 341 sucks the adhesive tape on the receiving table 27 and moves. When it moves to the pasting position, the adhesive tape is pasted on the FPC to be pasted. The right suction head component 2 repeats the work, and the right suction head 341 returns above the receiving table 27 of the right stripping knife component 16 and waits to suck the next piece of adhesive tape.

[0057] During the pasting process of the right suction head component 2, the left suction head component 12 will move above the receiving table 27 of the left stripping knife component 18 to suck the adhesive tape to be pasted. The action and process of sucking the adhesive tape are the same as those of the right suction head component 2 when sucking the adhesive tape. After the right suction head component 2 finishes pasting the adhesive tape and confirms safety, the left suction head component 12 also performs the pasting action along the X-axis guide rail 36 on the marble cross beam 3. The pasting action and process are the same as those of the right suction head component 2 when pasting the adhesive tape.

[0058] In the above process, the left suction head component 12 and the right suction head component 2 alternately suck and paste materials according to the above actions until all the positions of the adhesive tape to be pasted on the FPC to be pasted are pasted with adhesive tape.

[0059] (8) After all the positions of the adhesive tape to be pasted on the FPC to be pasted are pasted with adhesive tape, the carrier 8 drives the pasted FPC to run to the unloading position and stops vacuum adsorption. The unloading manipulator 5 of the loading and unloading component sucks the FPC pasted with adhesive tape from the carrier 8 and moves it to place it in the unloading tray 6.

[0060] At this time, one bonding cycle of the entire FPC board is completed.

[0061] In the embodiments of the present invention, usually, the FPCs to be pasted on the loading tray 10 do not have separator paper, but separator paper needs to be placed between each FPC with adhesive tape pasted to prevent scratches caused by friction between the FPCs. Therefore, after each FPC is pasted, the unloading manipulator 5 needs to take a piece of separator paper from the right separator paper tray 7 and place it on the FPC on the unloading tray 6.

[0062] If a stack of FPCs to be pasted in the loading tray 10 itself has separator paper, after the loading manipulator 11 sucks up a piece of FPC to be pasted, it is necessary to directly take the separator paper on the FPC to be pasted in the loading tray 10 into the unloading tray 6, and there is no need to place additional separator paper in the right separator paper tray 7. If some of the FPCs to be pasted have separator paper and it is required that the separator paper for loading is different from that for unloading, then for each FPC to be pasted loaded, the loading manipulator 11 needs to suck up the separator paper on the FPC to be pasted in the loading tray 10 and place it in the left separator paper tray 9. Then, after unloading, the unloading manipulator 5 sucks up a piece of another type of separator paper from the right separator paper tray 7 and places it in the unloading tray 6.

[0063] The medium-sized fully automatic adhesive pasting machine provided by the present invention realizes reliable peeling and pasting of the material tape through the loading platform, the loading and unloading assembly, the peeling knife assembly and the suction head assembly. The overall structure is simple, the size is small, the function is reliable and easy to implement, and its efficiency and stability are further improved. In addition, in the peeling knife assembly, the transfer suction cup assembly is used for sucking and peeling materials. When peeling materials with a very large and very thin size, it can prevent the materials from deforming and deviating during the peeling process, thereby improving the peeling accuracy and preventing peeling deformation, so as to ensure the pasting accuracy.

[0064] In summary, the above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
