[0064] Working principle of the present invention:

[0065] In this embodiment, the battery box includes a top cover and a box body, and a plurality of battery bodies are placed in the box body. The first feeding assembly includes a first conveyor belt 17, and the first conveyor belt 17 can horizontally convey the battery box. Figure 3 As shown, the battery tray moves horizontally from right to left. When the battery tray is delivered to the position of the first lifting mechanism 18, the first lifting mechanism 18 drives the battery tray to rise to the highest position of the first lifting mechanism 18. At this time, the separation multi-axis moving mechanism 191 can drive the separation clamping arm 19 to move along the Y axis (i.e. Figure 3The battery box is moved in the left and right directions and the Z-axis direction, and the battery box is clamped by the separation clamping arm 19 and transferred to the second conveyor belt 20. There are two first conveyor belts 17, and the two first conveyor belts 17 are arranged side by side. Therefore, the first lifting mechanism 18 is arranged between the two first conveyor belts 17 to facilitate lifting the battery box. The side walls of the battery box and the side walls of the top cover are provided with grooves to facilitate the buckling of the first claw 193 and the second claw 195; Figure 4 As shown, when the first hook 193 is in the closed state, it engages with the groove of the top cover, and when the second hook 195 is in the closed state, it engages with the groove of the box body; the first driving member 194 can simultaneously drive the two first hooks 193 to release the top cover or to close and engage the top cover, and the second driving member 196 can simultaneously drive the two second hooks 195 to release the box body or to close and engage the box body; when the separation clamping arm 19 transfers the battery box to the second conveyor belt 20, the second hook 195 is controlled to release the box body, and the first hook 193 is tightly engaged with the top cover. Due to the effect of gravity, the box body It falls to the second conveyor belt 20, and the top cover moves to another position for placing the top cover along with the separation clamping arm 19, so that the top cover is separated from the box body; a separation mounting plate 192 can be provided with an ejector and can pass through the top cover and then eject the box body located on the inner side of the second hook 195. At this time, the second hook 195 has released the box body, and the first hook 193 is closed and clamped to clamp the top cover. The ejector can select a retractable ejector structure, such as an electric push rod, a cylinder or other retractable structures. The separation mounting plate 192 is provided with a through hole that runs through it, so that the ejector can be retracted and passed through the through hole. When the second conveyor belt 20 brings the box carrying the battery body to the end, the multi-axis manipulator 8 of the loading and transferring mechanism 25 drives the grabbing arm 9 to grab the battery body on the box. The empty box Y-axis conveying mechanism 22 is arranged side by side with the second conveyor belt 20 in the form of belt conveyor. The empty box X-axis moving mechanism 21 and the empty box Z-axis moving mechanism 23 enable the empty box clamping mechanism 24 to grab the empty box after the battery body is clamped and move it to the empty box Y-axis conveying mechanism 22; the multi-axis manipulator 8 of the loading and transferring mechanism 25 controls the grabbing arm 9 to move the battery body to the pre-welding monitoring mechanism 30 for inspection to ensure that welding is carried out after the battery body inspection is passed. The qualified battery body after inspection by the pre-welding monitoring mechanism 30 is transferred to the third conveyor belt 26 for wiping through the battery transfer assembly 33. The front wiping mechanism 29 has the same structure as the rear wiping mechanism 31. The front wiping mechanism 29 wipes the battery body passing through the third conveyor belt 26 through a liftable wiping block. After wiping, the battery body is transferred to the clamping mechanism 6 through the grabbing arm 9 of the multi-axis manipulator 8 of the battery grabbing assembly.

[0066] In this embodiment, the nail upper monitoring mechanism 16 detects the sealing nails on the nail feeding assembly. The nail upper monitoring mechanism 16 includes a detection camera for detecting the sealing nails. The detection direction of the detection 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, and clamp the sealing nails on the nail feeding box.

[0067] The front involved in this embodiment is Figure 7 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 used as the center reference, the moving channel of the vacuum welding cabinet 1 and the door panel 5 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. The forward and backward movement of the door panel 5 cooperates with the vacuum welding cabinet 1 to realize the forward and backward movement of the battery material taking and releasing to the vacuum welding environment of the vacuum welding cabinet 1.

[0068] 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 detect 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.

[0069] 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.

[0070] 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. Fig.10 As 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;

[0071] The pressing assembly can press the battery body downward in the vertical direction. Fig.11 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.

[0072] In this embodiment, the positioning mechanism can be selected as a rangefinder camera, and the rangefinder camera 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 sealing nail position 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., and 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 for laser welding. 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 achieve 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 closure of the door panel 5. A pressure plate buffer 52 is set 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 the flexible pressing and closing of the door panel 5 on the moving channel.

[0073] 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 1. When the door panel 5 is closed, the vacuum welding cabinet 1 can perform vacuum treatment on the welding environment to improve the welding quality, remove excess air from the battery body, and increase the number of battery cycles.

[0074] The laser-welded battery body is transferred to the fourth conveyor belt 27 by the grabbing arm 9 of the battery grabbing assembly, and the post-wiping mechanism 31 wipes the laser-welded battery body, and then the post-welding monitoring mechanism 32 performs inspection, and the battery body that passes the inspection will be output, completing the battery body sealing nail welding process. The pre-welding monitoring mechanism 30, the in-welding monitoring mechanism 4, and the post-welding monitoring mechanism 32 can all select inspection units such as inspection cameras.

[0075] The door panel 5 includes a first pressing plate, a pressing plate buffer, and a second pressing plate which are connected in sequence; a second Y-axis moving mechanism 11 is arranged at the bottom of the vacuum welding cabinet, and a moving end of the second Y-axis moving mechanism 11 is connected to the first pressing plate.
