Description

Technical Field

[0001] The present invention relates to the technical field of flexible printed circuit board processing, and specifically relates to a full-automatic four-head high-speed laminating device. Background Art

[0028] In order to enable those skilled in the art of the present technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0029] Please refer to Figures 1 to 9, the present invention provides a fully automatic four-head high-speed laminating device, including a device body 1, a mounting seat 2 is fixedly connected to the device body 1, a fixed frame 3 is fixedly connected to the mounting seat 2, and a lifting mechanism 4 for supporting the reinforcing sheet is slidably connected to both sides of the mounting seat 2 where the fixed frame 3 is located. A suction mechanism 5 is fixedly connected to the bottom end of the fixed frame 3, and a rolling mechanism 6 for pressing the reinforcing sheet is slidably connected to the suction mechanism 5.

[0030] The suction mechanism 5 is provided to suck the reinforcing sheet on the feeder, move it to the mounting area through the moving structure on the device body 1, and perform mounting when reaching the mounting area. The lifting mechanism 4 supports the reinforcing sheet when the suction mechanism 5 sucks the reinforcing sheet, preventing it from falling during the movement of the reinforcing sheet and avoiding the situation of missed mounting. When the reinforcing sheet is being mounted, the provided rolling mechanism 6 rolls the reinforcing sheet, enabling the reinforcing sheet to be mounted more firmly and improving the mounting effect.

[0031] Please refer to Figure 4 、 Figure 6 、 Figure 7 and Figure 9, the suction mechanism 5 includes a sticker head 7 fixedly connected to the bottom end of the fixed frame 3. A pressing plate 8 is fixedly connected to the bottom end of the sticker head 7. An installation groove 9 is formed at a position of the sticker head 7 close to the pressing plate 8. A connecting plate 10 is fixedly connected between the sticker head 7 and the fixed frame 3. A first partition plate 11 is fixedly connected to one side of the connecting plate 10 located inside the fixed frame 3. One end of the first partition plate 11 is fixedly connected to the inner wall of the fixed frame 3. The other end of the first partition plate 11 is fixedly connected to a second partition plate 12. The second partition plate 12 is perpendicular to the first partition plate 11. The other end of the second partition plate 12 is fixedly connected to the fixed frame 3. A first sliding groove 13 is formed in the inner wall of the fixed frame 3 away from the first partition plate 11. A blocking partition plate 14 is slidably connected in the first sliding groove 13. The other end of the blocking partition plate 14 is slidably connected to the second partition plate 12. An adsorption cavity 15 is formed between the first partition plate 11, the second partition plate 12 and the inner wall of the fixed frame 3. An air inlet cavity 16 is formed between the second partition plate 12, the blocking partition plate 14 and the inner wall of the fixed frame 3. A release cavity 17 is formed between the first partition plate 11, the blocking partition plate 14 and the inner wall of the fixed frame 3. A first sliding plate 18 for closing the adsorption cavity 15 is slidably connected to the first partition plate 11. A second sliding plate 19 for closing the air inlet cavity 16 is slidably connected to the second partition plate 12. A sealing plate 20 for closing the release cavity 17 is fixedly connected to the inner wall of the fixed frame 3. A connecting frame 21 is fixedly connected to both the first sliding plate 18 and the second sliding plate 19. A threaded rod 22 is threadedly connected through the position of the blocking partition plate 14 located in the first sliding groove 13. A motor 23 is fixedly connected to the fixed frame 3 at a position corresponding to the threaded rod 22. The output end of the motor 23 is fixedly connected to the threaded rod 22. A first spring 24 is fixedly connected between the second sliding plate 19 and the connecting plate 10. A first through port 25 is formed in the connecting plate 10 at a position located inside the adsorption cavity 15. A second through port 26 is formed in the connecting plate 10 at a position located inside the release cavity 17. A blocking member 27 for blocking the second through port 26 is fixedly connected to the connecting plate 10 at the first through port 25.

[0032] In the initial state, under the action of the first spring 24, the second sliding plate 19 is close to the connecting plate 10. Through the connecting frame 21, the first sliding plate 18 is also close to the connecting plate 10, so that the spaces of the air inlet cavity 16 and the adsorption cavity 15 are small. At the same time, the partition plate 14 separates the air inlet cavity 16 and the release cavity 17. When the device performs chip mounting, air is input into the air inlet cavity 16 through the air inlet joint 55. The air pressure will push the second sliding plate 19 to move. The movement of the second sliding plate 19 drives the first sliding plate 18 to move through the connecting frame 21, so that the space of the adsorption cavity 15 increases, and the blocking member 27 blocks the second through port, so that negative pressure is generated in the chip head 7. The pressing plate 8 is close to the reinforcing patch, and the holes on the pressing plate 8 are blocked, so that the chip head 7 adsorbs the reinforcing patch, which is convenient for stably moving the reinforcing patch. When moving to the chip mounting area, the motor 23 is started. The motor 23 drives the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the partition plate 14 to move, so that the air inlet cavity 16 is communicated with the release cavity 17. Air enters the release cavity 17, and the air pressure in the air inlet cavity 16 decreases. Under the action of the first spring 24, the second partition plate 12 is driven to move. The movement of the second partition plate 12 drives the first partition plate 11 to move through the connecting frame 21. The movement of the first partition plate 11 generates a driving force to open the second through port 26, so that the release cavity 17 is communicated with the inside of the chip head 7, the pressure in the chip head 7 increases, and the chip head 7 can quickly separate from the reinforcing patch to perform the chip mounting of the reinforcing patch, and the reinforcing patch is pushed through the holes on the pressing plate 8 to be more firmly attached to the circuit board.

[0033] Please refer to Figure 9 As shown in the figure, the blocking member 27 includes a fixing frame 28 fixedly connected to the connecting plate 10 at the first through port 25. One end of the fixing frame 28 away from the connecting plate 10 is rotatably connected with a fixing ring 29. The fixing ring 29 is fixedly connected with a rotating frame 30 in the circumferential direction. One end of the rotating frame 30 is fixedly connected with a blocking block 31 for blocking the second through port 26. A rotating rod 32 is fixedly connected to the position of the first sliding plate 18 corresponding to the first through port 25. A spiral groove 33 is formed on the rotating rod 32. Vertical grooves 34 communicating with the spiral groove 33 are formed at both ends of the rotating rod 32 located in the spiral groove 33. A pushing block 35 is slidably connected in the spiral groove 33. The other end of the pushing block 35 is fixedly connected with the fixing ring 29.

[0034] When the first sliding plate 18 moves upward, the first sliding plate 18 drives the rotating rod 32 to move. The movement of the rotating rod 32 will cause the pushing block 35 to rotate along the spiral groove 33 and then move into the vertical groove 34, thereby driving the fixed ring 29 to rotate. The rotation of the fixed ring 29 drives the rotating frame 30 to rotate, and the rotation of the rotating frame 30 drives the blocking block 31 to block the second through port 26. When the blocking block 31 rotates away from the second through port 26, it will no longer rotate. When the blocking block 31 returns to block the second through port 26, the time for blocking the second through port 26 can be reduced, and the space connected to the adsorption cavity 15 can be reduced. Thus, a negative pressure can be generated faster in the suction head 7 to adsorb the reinforcing patch. The process of blocking the second through port 26 is opposite to the above process.

[0035] Please refer to Figure 2 and Figure 3 As shown in FIGS. and, the lifting mechanism 4 includes mounting plates 36 slidably connected to the mounting seat 2 on both sides of the fixed frame 3. At a position near the bottom end of the fixed frame 3 on each mounting plate 36, a rotating shaft 37 is rotatably connected through. Symmetrically fixed to the rotating shaft 37 are lifting hooks 38. At a position between the two lifting hooks 38 at the position of the rotating shaft 37, a gear 39 is fixedly connected. At a position corresponding to the gear 39 on the fixed frame 3, a rack 40 is fixedly connected. The gear 39 meshes with the rack 40. Fixedly connected to the bottom end of the mounting seat 2 is an electric push rod 41, and the electric push rod 41 is fixedly connected to the mounting plate 36 through a push rod.

[0036] When the suction head 7 adsorbs the reinforcing patch, the electric push rod 41 is started. The electric push rod 41 drives the mounting plate 36 to move through the push rod. The movement of the mounting plate 36 drives the rotating shaft 37 to move. The movement of the rotating shaft 37 drives the gear 39 to move. The gear 39 meshes with the rack 40. When the gear 39 moves, the gear 39 will drive the rotating shaft 37 to rotate. The rotation of the rotating shaft 37 drives the lifting hook 38 to rotate, so as to rotate under the reinforcing patch and support the adsorbed reinforcing patch, preventing the reinforcing patch from falling during the movement and avoiding the situation of missed mounting. When mounting, the process is opposite to the above. The lifting hook 38 will disengage from the reinforcing patch, thus not hindering the mounting of the reinforcing patch.

[0037] Please refer to Figure 5 and Figure 8, the rolling mechanism 6 includes a sliding block 42 slidably connected in the installation groove 9. One side of the sliding block 42 located in the installation groove 9 is fixedly connected with a connecting rod 43. One end of the connecting rod 43 is hinged with a connecting rod 44. One end of the sliding block 42 is fixedly connected with a second spring 45. The other end of the second spring 45 is fixedly connected with the head 7. The head 7 is ball-jointed with a rotating ball 46 at a position below the installation groove 9. A telescopic rod 47 is fixedly connected to the position of the rotating ball 46 outside the head 7. One end of the telescopic rod 47 is fixedly connected with a fixed rod 48. One end of the fixed rod 48 is fixedly connected with a moving rod 49. One end of the moving rod 49 is fixedly connected with a pressing roller 50. One side of the telescopic rod 47 close to the mounting plate 36 is hinged with a hinged rod 51. A rotating rod 52 is fixedly connected to the position of the hinged rod 51 close to the mounting plate 36. The rotating rod 52 is rotatably connected to a mounting rod 53 at a position away from the hinged rod 51. One end of the mounting rod 53 is fixedly connected with the mounting plate 36. A third spring 54 is fixedly connected between the mounting rod 53 and the hinged rod 51.

[0038] When performing the mounting, due to the continuous entry of air into the head 7, the internal pressure thereof increases. Thus, the air enters the telescopic rod 47 through the rotating ball 46, and the telescopic rod 47 elongates. The telescopic rod 47 will drive the fixed rod 48 to move. The movement of the fixed rod 48 drives the moving rod 49 to move. The movement of the moving rod 49 drives the pressing roller 50 to move, so as to perform rolling on the reinforcing patch. The mounting plate 36 moves upward. The movement of the mounting plate 36 drives the mounting rod 53 to move. The movement of the mounting rod 53 drives the hinged rod 51 to move. The hinged rod 51 moves and abuts against the fixed frame 3, so that the rotating rod 52 rotates. The rotation of the rotating rod 52 drives the hinged rod 51 to rotate. The rotation of the hinged rod 51 drives the telescopic rod 47 to rotate. The rotation of the telescopic rod 47 causes the pressing roller 50 to generate pressure on the reinforcing patch, so that the reinforcing patch can be more firmly mounted on the circuit board, improving the mounting effect. When the pressure in the head 7 increases, it will push the sliding block 42 to move. The movement of the sliding block 42 drives the connecting rod 43 to move. The movement of the connecting rod 43 drives the connecting rod 44 to move. The movement of the connecting rod 44 drives the hinged rod 51 to move. The movement of the hinged rod 51 drives the telescopic rod 47 to rotate around the rotating ball 46, so that the telescopic rod 47 moves towards the direction of the reinforcing patch, further increasing the pressure of the pressing roller 50 on the reinforcing patch, making the reinforcing patch more firmly mounted on the circuit board. When the mounting is completed, contrary to the above process, the telescopic rod 47 retracts, and the mounting plate 36 moves upward, so that the abutting rod is separated from the fixed frame 3. Under the action of the third spring 54 and the second spring 45, the pressing roller 50 is moved away from the reinforcing patch, avoiding blocking the adsorption of the subsequent reinforcing patch.

[0039] Please refer to Figure 3, one end of the hinge rod 51 far away from the telescopic rod 47 abuts against the fixed frame 3. When the hinge rod 51 abuts against the fixed frame 3, the telescopic rod 47 is made to approach the reinforcement piece, increasing the pressure of the pressing roller 50 on the reinforcement piece and improving the mounting effect of the reinforcement piece.

[0040] Please refer to Figure 3 and Figure 8 , the telescopic rod 47 is internally hollow and is connected to the inside of the attaching head 7 through a rotating ball 46, enabling the telescopic rod 47 to expand and contract through the air flow inside the attaching head 7.

[0041] Please refer to Figure 3 and Figure 8 , one end of the connecting rod 44 extends outside the attaching head 7 and is hinged to the telescopic rod 47, enabling the connecting rod 44 to push the telescopic rod 47 to rotate, making the telescopic rod 47 approach the reinforcement piece, increasing the pressure of the pressing roller 50 on the reinforcement piece and improving the mounting effect of the reinforcement piece.

[0042] Please refer to Figure 2 and Figure 7 , an air inlet joint 55 is fixedly connected to the outer wall of the fixed frame 3, and the air inlet joint 55 penetrates through the fixed frame 3 and is connected to the air inlet cavity 16. The adsorption and release of the reinforcement piece can be completed through one air inlet joint 55.

[0043] Please refer to Figure 6 , both the first through port 25 and the second through port 26 are connected to the inside of the attaching head 7, enabling the adsorption cavity 15 and the release cavity 17 to be connected to the attaching head 7 through the first through port 25 and the second through port 26, completing the adsorption and release process of the reinforcement piece.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
