[0068] Working principle of the present invention:

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

[0070] The front involved in this embodiment is Figure 1 The direction of the vacuum welding cabinet 1 toward the door panel 5, that is, the direction of the vacuum welding cabinet 1 close to the door panel 5 along the Y-axis direction is the front, and correspondingly, the side of the vacuum welding cabinet 1 away from the door panel 5 along the Y-axis direction is the rear (rear side); in this embodiment, the direction of the vacuum welding cabinet 1 close to the door panel 5 is the positive direction, that is, the vacuum welding cabinet 1 is taken as the center 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 the X-axis direction, and the up and down direction of the vacuum welding cabinet 1 is the Z-axis direction.

[0071] The multi-axis manipulator 8 can drive the grabbing arm 9 to rotate and move in multiple directions, and can clamp the battery body at different positions, and transfer the corresponding battery body to the clamp mechanism 6 for fixing; the grabbing unit 92 can include a finger cylinder and a clamping block, and the finger cylinder drives the clamping block to clamp the battery body. The grabbing sensing unit 93 can monitor whether there is a battery on the grabbing unit 92, and the grabbing sensing unit 93 can select a laser sensor. The grabbing unit 92 is installed on the grabbing mounting plate 91, and the clamping block of the grabbing unit 92 is provided with an elastic member, and the elastic member such as a spring and other elastic structures can ensure that the clamping block flexibly clamps the battery body to prevent the battery body from being clamped.

[0072] The pressing multi-axis moving mechanism of the pressing assembly includes a pressing X-axis moving mechanism, a pressing Y-axis moving mechanism, and a pressing Z-axis moving mechanism, which can meet the movement of the pressing adsorption mechanism 12 in the X-axis direction, the Y-axis direction, and the Z-axis direction; the pressing guide rail 121 is slidably matched with the sliding pressure claw 122, the pressing guide rail 121 is vertically arranged, and the sliding pressure claw 122 can be lifted and lowered along the pressing guide rail 121. The top of the sliding pressure claw 122 is connected to the pressing guide rail 121 or other structures through a pressing elastic member 123 to ensure the flexible downward pressing action of the sliding pressure claw 122. The sliding pressure claw 122 has an adsorption structure 13, and the lower end of the adsorption structure 13 is used to adsorb the sealing pin. The adsorption structure 13 can be connected to an external vacuum air path or other structure that can provide a negative pressure structure. The adsorption structure 13 of the sliding pressure claw 122 can set a vacuum value to achieve adsorption or release of the sealing pin. The bottom of the sliding pressing claw 122 in this embodiment is arranged horizontally, which increases the downward pressure of the sliding pressing claw 122 on the adsorbed sealing nail, and at the same time increases the overall strength of the sliding pressing claw 122, making the process of pressing down the sealing nail or transferring the sealing nail smoother.

[0073] The clamp mechanism 6 in this embodiment can accommodate two battery bodies at the same time. One battery body can be placed on the front side of the substrate and closely fit with the front pressing sheet. Figure 4As shown, at this time, the left-side pressing unit 64 on the left side of the substrate moves toward the side close to the front side pressing sheet and presses the battery body, and the front side unit moves toward the side close to the substrate and presses the battery body; another battery body can be placed on the rear side of the substrate and fit closely with the rear side pressing sheet, at this time, the right-side pressing unit 65 on the right side of the substrate moves toward the side close to the rear side pressing sheet and presses the battery body, and the rear side unit moves toward the side close to the substrate and presses the battery body; Figure 4 In the figure, A is the position where one battery body is placed in the clamp mechanism 6, and B is the position where another battery body is placed in the clamp mechanism 6.

[0074] The pressing assembly can press the battery body downward in the vertical direction. Figure 5 As shown, the top pressing unit 101 can be set according to the shape and structure of the battery body. The top pressing unit 101 in this embodiment is L-shaped to adapt to 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 blowing unit 103 to blow protective gas to 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 provided with a rubber coating treatment, and the spring allows the top pressing unit 101 to flexibly press the battery body to avoid crushing. The liquid suction unit 102 and the blowing unit 103 are driven by the top pressing Z-axis moving mechanism and are respectively 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 blowing unit 103 to collide with the battery body during the action process. The liquid suction unit 102 can absorb the electrolyte overflowed in the vacuum environment, and the air blowing unit 103 can be provided with an air blowing pipe connected to a protective gas source to provide a protective gas welding environment when cleaning, pre-welding, and fully welding the liquid filling port of the battery body.

[0075] In this embodiment, the positioning mechanism can be a rangefinder camera, which can be installed on the bracket through the 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 removal and nailing 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 movement of the clamp mechanism 6 in the Y-axis direction through the first Y-axis moving mechanism 7, and can realize the entry and exit of the vacuum welding cabinet 1. The door panel 5 can move forward and backward along the Y-axis direction to achieve 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 selected from elastic connectors such as springs. When the first pressure plate 51 or the second pressure plate 53 is pressed, the pressure plate buffer 52 can buffer the impact force and pressure, so as to achieve flexible compression and closure of the moving channel by the door panel 5. The welding monitoring mechanism 4 can be selected from a unit structure such as a monitoring camera that can be used to monitor the battery body.

[0076] The 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, the vacuum welding cabinet 1 can perform vacuum treatment on the welding environment, improve the welding quality, remove excess air from the battery body, and increase the battery cycle times.
