Description

Technical Field

[0001] The present invention relates to a production device for aluminum electrolytic capacitors, and particularly to a nail winding machine. Background Art

[0002] During the production process of aluminum electrolytic capacitors, it is necessary to wind the anode foil, electrolytic paper, and cathode foil to form a core package, and the whole process is completed by a nail winding machine. When winding, the anode foil, electrolytic paper, and cathode foil are all wound on the reel. In order to correct the positions of the anode foil and cathode foil when replacing the anode foil and cathode foil reels, several meters of electrolytic paper are connected to the leading end of each reel of anode foil and cathode foil when winding the anode foil and cathode foil. The electrolytic paper connected to the leading end replaces the anode foil and cathode foil to play a role in correction, and the electrolytic paper connected to the leading end can also play a role in protecting the anode foil. The price of electrolytic paper is much cheaper than that of the anode foil and cathode foil, so electrolytic paper is selected to be connected at the leading end and the trailing end.

[0003] As the nail winding progresses, the anode foil, electrolytic paper, and cathode foil on the anode foil reel, electrolytic paper reel, and cathode foil reel will be used up. The traditional method is to manually bond the material on a new reel to the material that is about to be used up with tape. The whole process needs to be completed with the machine stopped, and the core packages containing joints need to be manually removed.

[0004] When replacing the anode foil or cathode foil, first connect the reel, then pull out the extra-connected electrolytic paper, correct the position on the nail winding machine, tear off the electrolytic paper connected to the leading end of the anode foil or cathode foil, stick it on the anode foil or cathode foil with tape, and reserve a certain length of tape to connect to the anode foil or cathode foil that is about to be used up. When the anode foil or cathode foil being wound is about to be used up, manually stick the tape connected to the new anode foil or cathode foil on the anode foil or cathode foil that is about to be used up; such connection is very demanding on the technical proficiency of the operator, and the working intensity of the operator is very high because an operator needs to operate 6 - 8 nail winding machines, and each time it needs to be stopped, which affects the efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide an automatic material receiving device on a nail winding machine, so as to save manpower, improve efficiency, and ensure the connection quality when replacing the coil materials.

[0006] To solve the above technical problems, the technical solution proposed by the present invention is as follows: An automatic material receiving device on a nail winding machine, comprising a laminating assembly and a cutting device; the cutting device is arranged in front of the laminating assembly, an output wheel is arranged behind the laminating assembly, and two input wheels are arranged in front of the cutting device; the laminating assembly includes a pair of front laminating wheels and a pair of rear laminating wheels, and the two front laminating wheels and the two rear laminating wheels are respectively arranged opposite to each other; a material blocking protrusion is arranged between the front laminating wheels and the rear laminating wheels; a tape is attached to the interface end of the electrode foil (anode foil or cathode foil) or electrolytic paper to be connected, and the tape is placed at the position of the rear laminating wheel; at least one of the two rear laminating wheels is connected to a cylinder or an electromagnet.

The technical terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the scope of the present invention.

[0027] Embodiment 1

[0028] As Figure 1 shown, an automatic material receiving device on a staple roll machine includes a laminating assembly 3 and a cutting device 6; the cutting device 6 is arranged in front of the laminating assembly 3, a discharging wheel 1 is arranged behind the laminating assembly 3, two feeding wheels 2 are arranged in front of the cutting device 6, the laminating assembly 3 includes a pair of front laminating wheels 31 and a pair of rear laminating wheels 32, and the two front laminating wheels 31 and the two rear laminating wheels 32 are respectively arranged oppositely; a material blocking protrusion 4 is arranged between the front laminating wheel 31 and the rear laminating wheel 32; a tape 5 is attached to the interface end of the anode foil 8 to be connected, and the tape 5 is placed at the position of the rear laminating wheel 32. In this embodiment, the rear laminating wheel 32 and the front laminating wheel 31 arranged above are connected to a cylinder and move together during movement.

[0029] As Figure 1 shown, in this embodiment, the anode foil 8 to be connected is placed on the upper material blocking protrusion 4, and a section of tape 5 is attached to the anode foil 8 to be connected, and the reserved tape 5 is arranged below the upper rear laminating wheel 32. When connection is required, the upper rear laminating wheel 32 and the front laminating wheel 31 push the anode foil 8 to be connected downward, and when the upper rear laminating wheel 32 is tightly pressed against the lower rear laminating wheel 32, the anode foil to be connected is connected to the anode foil in use. In this embodiment, both the front laminating wheel 31 and the rear laminating wheel 32 are made of urethane rubber wheels and can rotate, so that the movement of the anode foil in use and the connected anode foil will not be hindered. In other embodiments, the two front laminating wheels 31 and the two rear laminating wheels 32 can be connected to a cylinder, but need to move simultaneously during movement, or the lower front laminating wheel 31 and the lower rear laminating wheel 32 can be connected to a cylinder, or only one of the two rear laminating wheels 32 can be connected to a cylinder.

[0030] As Figure 4As shown, in this embodiment, two material blocking protrusions 4 are provided and are arranged oppositely. The length of the material blocking protrusion 4 should be as short as possible, but it is necessary to ensure that the anode foil 8 to be connected will not fall when placed on the upper material blocking protrusion 4. The lower material blocking protrusion 4 only plays a certain isolation role to prevent the operator from accidentally touching the anode foil in use when the tape 5 on the anode foil to be connected is placed on the lower post-laminating wheel 32, thus affecting the anode foil being nailed and wound. The length of the material blocking protrusion 4 is as short as possible so that when the post-laminating wheel 32 and the pre-laminating wheel 31 push the anode foil to be connected, the anode foil to be connected can smoothly cross over the material blocking protrusion 4.

[0031] In this embodiment, the cutting device 6 includes a photoelectric detector 61 and a cutting assembly 62; the photoelectric detector 61 is arranged between the pre-laminating wheel 31 and the post-laminating wheel 32, there are two photoelectric detectors 61, and both are arranged directly facing the anode foil 8; the cutting assembly 62 is arranged in front of the pre-laminating wheel 31. In this embodiment, since both the head end and the tail end of the anode foil 8 on the reel are connected with electrolytic paper, and the color of the electrolytic paper is different from that of the anode foil, this color difference can be sensed by the photoelectric sensor. It is worth noting that when the material receiving device in this embodiment is connected to the electrolytic paper, a mark, such as a different color, should be made at the end of each roll of electrolytic paper as much as possible, so that the photoelectric sensor can sense it. It is also possible not to set a color, because when the electrolytic paper is used up, the photoelectric sensor can also sense it, but the subsequent calibration is very troublesome; because it is necessary to re-thread the electrolytic paper through each adjusting wheel.

[0032] In this embodiment, the cutting assembly 62 is arranged between the feeding wheel 2 and the laminating assembly 3. As Figure 2 and Figure 3 shown, the cutting assembly 62 includes a cushion block 621 and a cutting block 622. The cutting block 622 is arranged opposite to the end of the cushion block 621 and is arranged relatively, and the cutting block 622 can be cut off along the end of the cushion block 621. As Figure 2 and Figure 3 shown, in this embodiment, the head end of the cushion block 621 is arc-shaped.

[0033] In this embodiment, the cushion block 621 is connected to the machine wall 7 of the nailing and winding machine. An activity slot 623 is provided on the machine wall 7 of the nailing and winding machine at the position where the cutting block 622 is connected. One end of the cutting block 622 passes through the activity slot 623 and is connected to a cylinder or an electromagnet. In this embodiment, the cutting block 622 extends into the activity slot 623, so that it can be ensured that the anode foil on the cushion block 621 is completely cut off during cutting.

[0034] In this embodiment, a photoelectric inductor is used to detect whether the coiled material (anode foil, electrolytic paper or cathode foil) being wound is used up. When it is used up, the laminating assembly 3 is activated to connect a new coiled material to the nearly used-up coiled material through the tape 5, and the cutting device 6 cuts off the electrolytic paper behind the coiled material, thereby completing the automatic connection of the coiled material; the entire process does not require manual participation, and the operator only needs to replace the spool and perform calibration.
