[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The suction nozzle can be moved downward under the drive of the servo lifting slide to suck the separator paper in the paper tray and lift it up. Then the front and rear arms of the separator paper drive the product to move so that the product in the tray can be located under the separator paper.

After the separation paper is sucked, the suction nozzle will reset, and the pressing frame will stick to the upper part of the separation paper. At the same time, the reset spring pushes the tooth plate to reset it, and then the lower clamping frame will flip up and reset, so that the separation paper is clamped between the upper clamping frame and the lower clamping frame. At the same time, the suction nozzle releases the suction of the separation paper, and then the threaded rod rotates to drive the threaded sleeve to move down, so that the separation paper is pressed on the product by the pressing frame. The threaded sleeve is then moved onto the product, and then the threaded sleeve continues to move down. The pressing frame remains stationary due to the support of the product, and the spring is opened and contracted to allow the connecting frame to continue to move down under the drive of the threaded sleeve, so as to drive the paper spreading frame to move and push the paper spreading seat, so that the two paper spreading seats can move oppositely on the unfolding rod, and then drive the two groups of upper clamping frames and lower clamping frames to move oppositely to pull the partition paper, so that the partition paper is flattened and accurately laid on the product to avoid the phenomenon that the partition paper does not fully cover the product due to factors such as partition paper wrinkles, thereby ensuring the separation effect of the product.

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] like Figure 1-Figure 11 The shown device is used for loading and unloading materials in FPC processing, including a frame 1 and a feeding assembly installed on the frame 1. A servo lifting slide 8 is fixedly installed on the rear part of one side of the upper end of the frame 1, and a connecting frame 9 is fixedly installed on the servo lifting slide 8. The servo lifting slide 8 drives the connecting frame 9 to move up and down. Two nozzle seats 10 are symmetrically extended from the end of the connecting frame 9, and the connecting frame 9 serves to connect the nozzle seats 10. Two suction nozzles 11 are symmetrically installed through the upper ends of the two nozzle seats 10, and the nozzle seats 10 serve to support the suction nozzles 11. The suction nozzles 11 are connected to an external air pump to absorb the spacer paper. A paper support tray 37 is arranged below the suction nozzle 11, and the lower end of the paper support tray 37 is fixed to the frame 1. The paper support tray 37 serves to support the spacer paper. A paper spreading piece is arranged behind the paper support tray 37, and the paper spreading piece is connected to the frame 1.

[0030] The feeding assembly includes a tray lifting mechanism 2 installed at the front of the other side of the upper end of the frame 1. The tray lifting mechanism 2 is used for initial loading. The tray lifting mechanism 2 is driven by a screw motor to ensure the accuracy of the loading grabbing position. A positioning grabbing manipulator 3 is installed on the side of the frame 1. The positioning grabbing manipulator 3 uses a suction cup to suck the product and drives the product to move forward and backward and up and down to place it on the CCD alignment platform 4. A CCD alignment platform 4 is installed at the rear of the other side of the upper end of the frame 1. The CCD alignment platform 4 uses visual alignment to align the product, that is, the camera data is used to automatically align the product placed on the alignment platform as required, thereby saving workers' loading time. This method effectively solves the problem that traditional equipment can only use a manipulator to pick up materials, but cannot automatically align, and workers need to manually align. The phenomenon of alignment and alignment can be achieved, which effectively saves loading time and speeds up loading, thereby improving the operation efficiency of the equipment. A loading arm 5 is installed in the middle of the upper end of the frame 1. The loading arm 5 uses a suction cup to absorb the product and drives the product to move left and right and up and down to place it on the mold. A discharging arm 6 is installed at the front of one side of the upper end of the frame 1. The discharging arm 6 uses a suction cup to absorb the product and drives the product to move left and right and up and down to remove it from the mold and place it in the receiving tray of the front and rear paper separation arms 7. The front and rear paper separation arms 7 are arranged below the discharging arm 6. The front and rear paper separation arms 7 can drive the product to move back and forth. The front and rear paper separation arms 7 are connected to the frame 1. Because the above-mentioned control and product absorption methods are existing technologies and have been widely used, they are not elaborated in detail here.

[0031] The paper unfolding part includes a frame 14 arranged at the rear of the paper supporting tray 37, the frame 14 is fixed to the frame 1, and a threaded rod 18 is rotatably installed between the upper and lower end surfaces inside the frame 14, and the frame 14 plays a role in supporting the threaded rod 18, and the threaded rod 18 passes through the upper end of the frame 14, and a threaded sleeve 17 is screwed on the outer surface of the threaded rod 18, and the threaded rod 18 plays a role in driving the threaded sleeve 17 to move up and down, and an unfolding rod 12 is elastically installed at the front end of the threaded sleeve 17, and two paper unfolding seats 26 are symmetrically and slidably installed on the outer surface of the unfolding rod 12, and the unfolding rod 12 plays a role in guiding the paper unfolding seats 26, and the front ends of the two paper unfolding seats 26 are fixedly installed with upper clamping frames 24, and the paper unfolding seats 26 play a role in supporting the upper clamping frames 24 and the lower clamping frames 36, and a pressing frame 35 is fixedly installed in the middle of the front end of the unfolding rod 12.

[0032] A lower clamping frame 36 is provided below the upper clamping frame 24, and the lower clamping frame 36 is rotatably connected to the paper spreading seat 26. The height of the pressing frame 35 is lower than that of the lower clamping frame 36, which can ensure that after the spacer paper is laid, the lower clamping frame 36 will not scratch the spacer paper when it is reset. Sliding ears 19 extend from both sides of the threaded sleeve 17, and the sliding ears 19 slide through both sides of the frame 14. The sliding ears 19 play a role in guiding the threaded sleeve 17. A guide column 21 is fixedly installed in the middle part of the upper end of the unfolding rod 12, and a connecting frame 20 is slidably installed on the outer surface of the guide column 21. The guide column 21 plays a guiding role, and the connecting frame 20 plays a pressing role. The end of the connecting frame 20 is fixed to the front end of the threaded sleeve 17.

[0033] A servo motor 15 is fixedly installed on the upper end of the frame 14, and the output end of the servo motor 15 is fixed to the threaded rod 18. The servo motor 15 drives the threaded rod 18 to rotate. An opening spring 22 is wound around the outer side of the guide column 21. One end of the opening spring 22 is fixed to the unfolding rod 12, and the other end of the opening spring 22 is fixed to the lower end of the connecting frame 20. The opening spring 22 adopts a spring with relatively large elasticity to ensure that the product will not be damaged when the pressing frame 35 is pressed on the product. A positioning cap 25 is coaxially inlaid on the upper end of the guide column 21. The positioning cap 25 is attached to the upper end of the connecting frame 20, and the positioning cap 25 prevents the guide column 21 and the connecting frame 20 from separating.

[0034] The two sides of the connecting frame 20 are rotatably installed with paper display frames 23, and the ends of the paper display frames 23 are rotatably connected to the paper display seats 26. The paper display frames 23 can push the paper display seats 26 so that the two paper display seats 26 can move in opposite directions on the unfolding rod 12, thereby driving the two groups of upper clamping frames 24 and lower clamping frames 36 to move in opposite directions to pull the partition paper so that the partition paper is flattened and accurately laid on the product. The lower part of the paper display seat 26 is rotatably installed with a shaft body 32, and the end of the lower clamping frame 36 is embedded in the outer surface of the shaft body 32. The shaft body 32 serves to connect the lower clamping frame 36. The end of the shaft body 32 is coaxially embedded with a gear 33, and the lower part of the gear 33 is meshed with a tooth plate 34. The gear 33 and the tooth plate 34 serve to drive the lower clamping frame 36 to flip down, and the tooth plate 34 is elastically connected to the paper display seat 26.

[0035] A push rail 16 is fixedly installed at the end of the nozzle seat 10. The lower end surface of the push rail 16 is arranged in an inclined surface, which can facilitate pushing the guide wheel 31. The guide wheel 31 is fitted on the inclined surface of the push rail 16. The guide wheel 31 is connected to the tooth plate 34. A fixing frame 27 is fixedly installed at the rear end of the paper unfolding seat 26. A reset rod 29 is fixedly installed at the rear end of the tooth plate 34. The fixing frame 27 plays a role in supporting the reset rod 29. The reset rod 29 slides through both ends of the fixing frame 27. The reset rod 29 plays a role in driving the tooth plate 34 to move and reset.

[0036] Guide frames 30 are slidably installed through both sides of the toothed plate 34. One end of the guide frame 30 is fixed to one end of the fixed frame 27. The guide frame 30 functions to guide the toothed plate 34. A convex cap 28 is coaxially inlaid on the outer surface of the reset rod 29. The convex cap 28 abuts against one end of the fixed frame 27. A reset spring 13 is wound around the outside of the reset rod 29. The convex cap 28 functions to be pushed by the reset spring 13. One end of the reset spring 13 is fixed to the other end of the fixed frame 27, and the other end of the reset spring 13 is fixed to the convex cap 28. The reset spring 13 can push the reset rod 29, thereby driving the toothed plate 34 to move and resetting it.

[0037] During use, the worker places the product on the tray lifting mechanism 2 as required. The positioning and grasping manipulator 3 grabs the product from the tray lifting mechanism 2 and places it on the CCD positioning platform 4. The CCD positioning platform 4 uses visual positioning and automatically positions the product placed on the positioning platform correctly according to the camera data. After the positioning is completed, the feeding arm 5 grabs the product from the CCD positioning platform 4 and places it into the punching die for punching. After punching is completed, the unloading arm 6 grabs the product from the die and places it into the receiving tray of the paper separating front and rear arms 7. Then, the suction nozzle 11 is driven by the servo lifting slide 8 to move downward to suck and lift the paper separator in the paper tray 37 upward. During this process, when the suction nozzle 11 moves downward, the push rail 16 will move downward synchronously to push the guide wheel 31 through the inclined surface on the push rail 16, causing the toothed plate 34 to move, thereby driving the gear 33 to rotate and making the lower clamping frame 36 turn down by ninety degrees. After the paper separator is sucked, when the suction nozzle 11 resets, the pressing frame 35 will abut against the upper part of the paper separator. At the same time, the reset spring 13 pushes the toothed plate 34 to reset it, thereby causing the lower clamping frame 36 to turn up and reset to clamp the paper separator between the upper clamping frame 24 and the lower clamping frame 36. At the same time, the suction nozzle 11 releases the suction of the paper separator. Subsequently, the paper separating front and rear arms 7 drive the product to move so that the product in the tray can be located below the paper separator. Then, the threaded rod 18 rotates to drive the threaded sleeve 17 to move downward to press the paper separator onto the product by means of the pressing frame 35. Subsequently, the threaded sleeve 17 continues to move downward. The pressing frame 35 remains stationary under the support of the product, and the opening spring 22 contracts and deforms, causing the connecting frame 20 to continue to move downward under the drive of the threaded sleeve 17 to drive the paper unfolding frame 23 to move and push the paper unfolding seat 26, enabling the two paper unfolding seats 26 to move in opposite directions on the unfolding rod 12, thereby driving the two groups of upper clamping frames 24 and lower clamping frames 36 to move in opposite directions to pull the paper separator, flatten the paper separator, and accurately lay it on the product. This cycle separates each layer of products, completing one processing process.
