[0068] The working principle of this utility model:

[0069] In this embodiment, the top nail monitoring mechanism 16 monitors the sealing nails on the nail feeding assembly. The top nail monitoring mechanism 16 includes a monitoring camera for monitoring the sealing nails. The monitoring camera is set with the monitoring direction facing downward. The nail feeding assembly is provided with multiple stackable nail feeding boxes, nail feeding box guide rails, and nail feeding lifting mechanism. The nail feeding boxes containing the sealing nails are transported along the nail feeding box guide rails. The top nail moving assembly 14 includes a top nail X-axis moving module, a top nail Y-axis moving module, and a top nail Z-axis moving module. The top nail moving assembly 14 can drive the top nail gripping assembly 15 to move along the X-axis, Y-axis, and Z-axis directions. The top nail gripping assembly 15 can be provided with a clamping structure, a suction cup, or a suction nozzle, etc., which can be used to grip the sealing nails on the nail feeding box.

[0070] The front part involved in this embodiment is Figure 1 The direction in which the vacuum welding cabinet 1 faces the door panel 5, that is, the direction along the Y-axis of the vacuum welding cabinet 1 closest to the door panel 5, is the front. Correspondingly, the side of the vacuum welding cabinet 1 away from the door panel 5 along the Y-axis is the rear (rear side). In this embodiment, the direction of the vacuum welding cabinet 1 closest to the door panel 5 is taken as the positive direction. That is, with the vacuum welding cabinet 1 as the central reference, the moving channel of the vacuum welding cabinet 1 and the door panel 5 are in the front direction, that is, in the Y-axis direction. The left and right sides of the vacuum welding cabinet 1 are in the X-axis direction, and the up and down direction of the vacuum welding cabinet 1 is in the Z-axis direction.

[0071] The multi-axis robotic arm 8 can drive the gripping arm 9 to rotate and move in multiple directions, clamping battery bodies at different positions and transferring them to the clamping mechanism 6 for fixation. The gripping unit 92 may include a finger cylinder and a gripping block. The finger cylinder drives the gripping block to clamp the battery body. The gripping sensing unit 93 can detect whether there is a battery on the gripping unit 92, and the gripping sensing unit 93 may be a laser sensor. The gripping unit 92 is mounted on the gripping mounting plate 91. The gripping block of the gripping unit 92 is equipped with an elastic element, such as a spring, to ensure that the gripping block flexibly clamps the battery body and prevents the battery body from being damaged.

[0072] The pressing assembly's multi-axis moving mechanism includes a pressing X-axis moving mechanism, a pressing Y-axis moving mechanism, and a pressing Z-axis moving mechanism, which can satisfy the movement of the pressing adsorption mechanism 12 in the X-axis, Y-axis, and Z-axis directions. The pressing guide rail 121 and the sliding claw 122 are slidably engaged. The pressing guide rail 121 is vertically set, and the sliding claw 122 can move up and down along the pressing guide rail 121. The top of the sliding claw 122 is connected to the pressing guide rail 121 or other structures through a pressing elastic element 123 to ensure the flexible downward pressing action of the sliding claw 122. The sliding claw 122 has an adsorption structure 13. The lower end of the adsorption structure 13 is used to adsorb the sealing nail. The adsorption structure 13 can be connected to external vacuum circuits or other structures that can provide negative pressure. The adsorption structure 13 of the sliding claw 122 can be set with a vacuum value to achieve the adsorption or release of the sealing nail. In this embodiment, the bottom of the sliding pressure claw 122 is set horizontally, which increases the downward pressure of the sliding pressure claw 122 on the adsorbed sealing nail, and at the same time increases the overall strength of the sliding pressure claw 122, making the process of pressing down the sealing nail or transferring the sealing nail more stable.

[0073] In this embodiment, the clamping mechanism 6 can simultaneously accommodate two battery bodies. One battery body can be placed on the front side of the substrate and closely fitted to the front pressure plate, such as... Figure 4 As shown, at this time, the left pressing unit 64 on the left side of the substrate moves toward the side closer to the front pressing plate and presses the battery body, and the front unit moves toward the side closer to the substrate and presses the battery body; another battery body can be placed on the rear side of the substrate and closely attached to the rear pressing plate. At this time, the right pressing unit 65 on the right side of the substrate moves toward the side closer to the rear pressing plate and presses the battery body, and the rear unit moves toward the side closer to the substrate and presses the battery body. Figure 4 In the diagram, point A is the position where one battery body is placed in the clamping mechanism 6, and point B is the position where another battery body is placed in the clamping mechanism 6.

[0074] The top pressure assembly can press the battery body downwards in the vertical direction, such as... Figure 5As shown, the top pressing unit 101 can be set according to the shape and structure of the battery body. In this embodiment, the top pressing unit 101 is L-shaped to fit the battery body to be processed. The top pressing unit 101 can flatten the top of the battery body, use the liquid suction unit 102 to suck liquid from the battery body, and use the air blowing unit 103 to blow protective gas into the battery body. The top pressing unit 101 is connected to the lifting end of the top pressing Z-axis moving mechanism through a spring. The top pressing unit 101 can also be equipped with a rubber coating treatment. With the spring, the top pressing unit 101 can flexibly press the battery body to avoid damage. The liquid suction unit 102 and the air blowing unit 103 are both driven by the top pressing Z-axis moving mechanism and are located on one side of the top pressing unit 101 to avoid the top pressing unit 101 causing the liquid suction unit 102 and the air blowing unit 103 to collide with the battery body during the operation. The liquid suction unit 102 can suck up the electrolyte overflowing under vacuum, and the air blowing unit 103 can be equipped with an air blowing pipe connected to a protective gas source to provide a protective gas welding environment during cleaning, pre-welding, and full welding of the battery body's liquid injection port.

[0075] In this embodiment, the positioning mechanism can be a rangefinder camera, which can be mounted on a bracket via a camera mounting structure. The bracket is located on one side of the support frame. The rangefinder camera can obtain the position of the sealing nail to guide the nail-picking and nail-installing action of the sliding pressure claw 122. The laser emission mechanism 3 includes a galvanometer unit, a scene unit, etc. The lifting mechanism 2 can drive the laser emission mechanism 3 to move up and down. The laser beam passing through the laser emission mechanism 3 can enter the vacuum welding cabinet 1 through the laser processing channel to perform laser welding on the battery body and the sealing nail. The moving channel can meet the needs of the clamping mechanism 6 to move in the Y-axis direction via the first Y-axis moving mechanism 7, which can realize entry and exit of the vacuum welding cabinet 1. The door panel 5 can move back and forth along the Y-axis direction to realize the sealing closure of the vacuum welding cabinet 1 and the flexible closing of the door panel 5. A pressure plate buffer 52 is provided between the first pressure plate 51 and the second pressure plate 53. The pressure plate buffer 52 can be an elastic connecting component such as a spring. When the first pressure plate 51 or the second pressure plate 53 is subjected to pressure, the pressure plate buffer 52 can buffer the impact force and pressure, realizing the flexible pressing and closing of the door panel 5 on the moving channel. The welding monitoring mechanism 4 can be a unit structure such as a monitoring camera that can be used to monitor the battery body.

[0076] Vacuum welding cabinet 1 is connected to a negative pressure pipe, which can be connected to an external negative pressure device or equipped with a negative pressure unit to perform vacuum treatment on the closed and sealed vacuum welding cabinet. When the door panel 5 is closed, vacuum welding cabinet 1 can perform vacuum treatment on the welding environment, improve welding quality, remove excess air from the battery body, and increase the battery cycle life.
