[0002] In the process of automated production and processing, there is a situation where the inner core needs to be glued to the outer cover. The main processing steps are as follows: first, the outer cover is glued, and then the inner core is loaded into the outer cover, and the inner core and the outer cover are fixed with glue to complete the entire processing process of glue-pointing and buckling.

[0003] The prior art glue dispensing and buckling cover process mainly relies on the glue dispensing and buckling cover processing line to be implemented.

The specific structure and principle adopt the existing technology and will not be described in detail. The glue dispensing head 48 can be conveniently moved and adjusted to a position aligned with the cover body to be glued. The glue is pumped into the glue mixing pipe 46 by the pressure pump in the glue tank. The two kinds of glue are mixed in the glue mixing pipe 46 and then diverted to the two glue dispensing heads 48 through the diverter seat 47. Finally, the two glue dispensing heads 48 respectively apply the glue to the two covers on the same material tray to realize the glue dispensing action.

[0044] After the glue-dispensed cover is transported to the bottom of the positioning circle 54, the CCD camera B53 can be used to take photos of the glue-dispensed area inside the cover. If the glue-dispensing meets the requirements, the feeding conveyor belt 31 will continue to transport the glue-dispensed cover downstream. If the glue-dispensing is unqualified, the unqualified product will be transferred by the NG transfer unit 6. In addition, the positioning circle 54 can block other objects around the shooting to prevent other objects from interfering with the photo detection.

[0045] Specifically, the NG transfer unit 6 includes an NG conveyor belt 61, a column B62, a front and rear cylinder 63, a lifting cylinder 64 and a gripper 65.

The turning surface mechanism 72 is used to clamp the inner core body supplied by the feeding conveyor belt 71 and then turn it over. The inner core body is transported from the upstream end to the downstream end by the feeding conveyor belt 71. The inner core body is tightened and turned over 180 degrees by the turning surface mechanism 72 to achieve the change of surface, thereby ensuring the correct position of the inner core body and the cover body when assembled.

[0048] Among them, the flipping mechanism 72 includes a mounting frame B721 fixed on the workbench 1, a driving motor 722 fixed on the side of the mounting frame B721, a shaft 723 rotatably mounted on the top of the mounting frame B721, a pulley group 724 arranged on the side of the mounting frame B721, a clamping pneumatic cylinder A725 fixed on the end of the shaft 723, and a pair of clamping claws A726 arranged on the two moving ends of the clamping pneumatic cylinder A725.

The transmission method adopts the existing technology, and the specific structure and working principle are not described in detail. When the clamping pneumatic cylinder A725 works, its two moving ends can drive the two clamping claws A726 to move closer to or away from each other.

[0049] By driving the motor 722, the shaft 723 is driven to rotate under the transmission action of the pulley group 724, which can then drive the clamping pneumatic cylinder A725 and the clamping jaws A726 to swing synchronously, providing effective drive for the rotation and surface changing action. When the two clamping jaws A726 are driven to approach each other by the clamping pneumatic cylinder A725, the inner core body of the material can be clamped to facilitate the surface changing.

The clamping end 88 is fixed at the bottom of the connecting seat 87. The clamping end 88 is aligned with the feeding conveyor belt 31.

[0051] The operation of cylinder A82 and cylinder B83 can drive the clamping pneumatic cylinder B84 and the clamping claw B85 to move and adjust, thereby realizing the transfer and feeding of the inner core. Cylinder A82 and cylinder B83 adopt existing technology, and the specific structure and working principle are no longer described in detail. When taking materials, the clamping pneumatic cylinder B84 drives the two clamping claws B85 to approach each other, and the inner core after the surface change is tightened. Then, the clamping pneumatic cylinder A725 drives the two clamping claws A726 to move away from each other to release the inner core. Then, the cylinder A82 and cylinder B83 work to transfer the inner core to the cover body after gluing. Then, the clamping pneumatic cylinder B84 drives the two clamping claws B85 to move away from each other to release the inner core.

[0052] As the feeding conveyor belt 31 continues to convey, when the cover body containing the inner core moves to the west of the clamping end 88, the downward pressure cylinder 86 extends and works, and under the fixed connection of the connecting seat 87, the clamping end 88 is driven downward, so that the inner core can be pressed into the cover body, completing the press-fitting of the inner core.

[0053] In addition, two groups of feeding conveyor belts 71 and flip-over mechanisms 72 are arranged. One feeding conveyor belt 71 and one flip-over mechanism 72 work together to form two inner core feeding lines for the inner core. Two groups of press-fitting units 8 are also arranged, and each group of press-fitting units 8 works together with each inner core feeding line to realize the inner core transfer structure at two locations, so that it can match the two placement positions for the cover body on the material tray, and the overall structural layout is reasonable.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
