[0002] In the assembly line production of lithium-ion batteries, the battery needs to be evacuated and filled with helium after the secondary filling process, and a special nail inserter is used to insert a plastic sealing nail into the filling hole of the lithium-ion battery to seal it. The subsequent metal sealing nail welding and helium inspection process are then carried out.

[0003] The existing sealing nail removal device generally uses a nail prevention device and a robot to take and place nails. Not only is the nail placement unstable and prone to jamming, but the sealing nails are also small in size and inconvenient to take and place. The pass rate of the robot to take and place nails is not good, and the efficiency of manual insertion of plastic sealing nails is low, resulting in difficulty in improving the efficiency of the nailing mechanism and poor quality.

[0004] Therefore, a new battery sealing nail removal device is needed to improve the stability and efficiency of this workstation to meet the higher production capacity requirements of the injection system. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0026] See also Figure 1-3 In this embodiment, a sealing nail removing device includes a vibration plate 1, a nail feeding mechanism 2 and a nail removing and placing mechanism 3, wherein:

[0027] The vibration plate 1 also includes a material channel 11 provided at the nail outlet end thereof. The vibration plate 1 arranges the sealing nails with their tips facing upwards through its own vibration and moves them onto the material channel 11. The upper end surface of the vibration plate 1 has a spiral structure (not shown in the figure), which is a prior art and will not be described in detail here.

[0028] The nail feeding mechanism 2 includes a nail feeding plate 21, a nail suction tube 22 and a nail feeding tube 23 arranged on the nail feeding plate 21; the nail feeding plate 21 is placed vertically, the number of the nail suction tubes 22 is 2, the number of the nail feeding tubes 23 is 4, the nail suction tubes 22 and the nail feeding tubes 23 are arranged on the same horizontal plane, and the nail suction tube 22 is located in the middle of the nail feeding tubes 23;

[0029] The nail picking and placing mechanism 3 includes a nail head 31 for sucking sealing nails, a positive and negative pressure converter 32 connected to the rear end of the nail head 31, and an aperture detector 24 for detecting the position of the sealing nail; a sliding unit 33 that drives the nail head 31 to move horizontally in a direction parallel to the nail feeding plate 21; and the nail head 31 is on the same horizontal plane as the nail sucking tube 22 and the nail feeding tube 23. The inside of the nail head 31 has a hollow structure connected to the pipeline of the positive and negative pressure converter 32. When sucking nails, the positive and negative pressure converter 32 generates negative pressure. Since the nail sucking tube 22 is very short, the sealing nail is sucked to the end of the nail head 31 due to the suction force. The aperture detector 24 detects whether the sealing nail exists and whether it meets the arrangement of the pointed head facing outward. The aperture detector 24 feeds back information to the host computer. When the state of the sealing nail is not correct, the host computer controls the positive and negative pressure converter 32 to break the vacuum with positive pressure, and the sealing nail falls naturally and is then collected in a centralized manner.

[0030] Furthermore, the discharge end of the material channel 11 is on the same horizontal plane as the nail suction tube 22, and the material channel 11 is slightly inclined upward. When the sealing nails are arranged on the material channel 11 under the action of vibration, they gradually approach the nail suction tube 22. Since the sealing nails themselves are light in weight, they are easily sucked by the nail heads 31 under negative pressure.

[0031] Furthermore, the sliding unit 33 includes an L-shaped plate 331, a connecting plate 332 slidably connected to the bottom end of the L-shaped plate 331, and a cylinder driving the L-shaped plate 331 to slide relative to the connecting plate 332; the rear end of the nail head 31 passes through the vertical section of the L-shaped plate 331 and is fixedly connected thereto. The L-shaped plate 331 drives the nail head 31 to move horizontally, and when the nail head 31 is in a coaxial position with the nail suction tube 22, the positive-negative pressure converter 32 generates negative pressure, causing the nail head 31 to generate suction; when the nail head 31 moves to a position coaxial with the nail delivery tube 23, the positive-negative pressure converter 32 generates positive pressure, causing the nail head to generate thrust, sending the sealing nail into the nail delivery tube 23, and then transmitting it to the nail pressing mouth of the nail driving device, pressing the sealing nail down and driving it into the injection hole.

[0032] Furthermore, the nail suction tube 22 is a straight tube with a very short length, which makes it easier for the nail head 31 to absorb the sealing nail; the nail delivery tube 23 is a curved tube with the bending direction facing upward, which is connected to the air pipe of the nailing device to implement subsequent nailing actions.

[0033] When the utility model is in operation, the sealing nails are placed on the vibration plate 1. Under the action of vibration, the sealing nails are arranged with their pointed ends facing upward, and gradually move to the material channel 11, close to the nail suction tube 22. The positive and negative pressure converter 32 generates negative pressure on the nail head 31, and the sealing nail passes through the nail suction tube 22 and is sucked on the nail head 31. The aperture detector 24 monitors the state of the sealing nail on the nail head in real time. When the sealing nail is sucked on the nail head 31 with its pointed end facing outward, the system continues to operate; the L-shaped plate 331 drives the nail head 31 to move to the nail feeding tube 23 on one side, at which time the positive and negative pressure converter 32 generates positive pressure on the nail head 31, pushing the sealing nail into the nail feeding tube 23, and then entering the nail driving device to perform the nail driving action; then, the nail head 31 returns to the nail suction tube 22, continues to absorb the sealing nail, and moves toward the nail feeding tube 23 on the other side, and sends the sealing nail into the nail feeding tube 23 in the same way, forming a circular motion. When the sealing nail is not sucked on the nail head with the pointed end facing outward, the positive pressure of the positive and negative pressure converter 32 breaks the vacuum, the sealing nail falls naturally, and the nail head 31 sucks the sealing nail from the nail suction tube 22 again until the sealing nail is in a correct state.

[0034] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0035] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
