[0063] The nail feeding assembly is located on one side of the vacuum welding cabinet 1, and a nail feeding monitoring mechanism 16 is installed above the nail feeding assembly.

[0064] The working principle of this utility model:

[0065] In this embodiment, the battery compartment comprises a top cover and a housing. The housing contains several battery cells. The first feeding assembly includes a first conveyor belt 17, which horizontally transports the battery compartment, as shown in the attached diagram. Figure 3 As shown, the battery compartment moves horizontally from right to left. When the battery compartment is delivered to the position of the first lifting mechanism 18, the first lifting mechanism 18 drives the battery compartment to rise to its highest position. At this time, the separation multi-axis moving mechanism 191 can drive the separation clamping arm 19 along the Y-axis (i.e., Figure 3The battery case moves along the left and right directions (Z-axis direction) and is clamped by the separating clamping arm 19 and transferred to the second conveyor belt 20. There are two first conveyor belts 17 arranged side-by-side; therefore, the first lifting mechanism 18 is positioned between the two first conveyor belts 17 to facilitate lifting the battery case. Grooves are provided on the side walls of the battery case and the side walls of the top cover to facilitate the engagement of the first hook 193 and the second hook 195. Figure 4 As shown, when the first hook 193 is closed, it engages the groove of the top cover; when the second hook 195 is closed, it engages the groove of the housing. The first drive unit 194 can simultaneously drive both first hooks 193 to release the top cover or to close the top cover, and the second drive unit 196 can simultaneously drive both second hooks 195 to release the housing or to close the housing. When the separating clamping arm 19 transfers the battery box onto the second conveyor belt 20, it controls the second hooks 195 to release the housing, and the first hooks 193 to close the top cover. Due to gravity, the housing... The top cover falls onto the second conveyor belt 20, while the top cover moves to another position with the separation clamping arm 19, thus separating the top cover from the box body. The separation mounting plate 192 can be equipped with an ejector that can pass through the top cover and eject the box body located inside the second hook 195. At this time, the second hook 195 has released the box body, and the first hook 193 closes and clamps the top cover. The ejector can be a telescopic ejection structure, such as an electric push rod, cylinder, or other telescopic structure. The separation mounting plate 192 has a through hole that passes through it, so that the ejector can telescopically pass through the through hole. When the second conveyor belt 20 brings the battery-carrying box to the end, the multi-axis robot 8 of the loading and transfer mechanism 25 drives the gripping arm 9 to grab the battery-carrying box. The empty box Y-axis conveying mechanism 22 is set up in parallel with the second conveyor belt 20 in the form of belt conveying. 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 and transfer the empty box after the battery-carrying box is clamped to the empty box Y-axis conveying mechanism 22. The multi-axis robot 8 of the loading and transfer mechanism 25 controls the gripping arm 9 to move the battery-carrying box to the pre-welding monitoring mechanism 30 for inspection, and ensures that the battery-carrying box passes the inspection before welding. After passing the inspection by the pre-welding monitoring mechanism 30, the qualified battery body is transferred to the third conveyor belt 26 by the battery transfer assembly 33 for wiping. The front wiping mechanism 29 and the rear wiping mechanism 31 have the same structure. The front wiping mechanism 29 wipes the battery body passing through the third conveyor belt 26 by a liftable wiping block. After wiping, the battery body is transferred to the clamping mechanism 6 by the gripping arm 9 of the multi-axis manipulator 8 of the battery gripping assembly.

[0066] In this embodiment, the top nail monitoring mechanism 16 detects the sealing nails on the nail feeding assembly. The top nail monitoring mechanism 16 includes a detection camera for detecting the sealing nails, which is set with the detection 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.

[0067] The front part involved in this embodiment is Figure 7 The direction of the vacuum welding cabinet 1 facing the door panel 5, that is, the direction along the Y-axis closer to the door panel 5, is considered the front. Correspondingly, the side of the vacuum welding cabinet 1 away from the door panel 5 along the Y-axis is considered the rear (rear side). In this embodiment, the direction of the vacuum welding cabinet 1 closer 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, i.e., in the Y-axis direction. The left and right directions 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. The forward and backward movement of the door panel 5, in conjunction with the vacuum welding cabinet 1, enables the battery to be moved forward and backward into the vacuum welding environment of the vacuum welding cabinet 1.

[0068] 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.

[0069] 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.

[0070] 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 10 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.

[0071] The top pressure assembly can press the battery body downwards in the vertical direction, such as... Figure 11 As 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.

[0072] 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 for laser welding. 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, enabling entry and exit from the vacuum welding cabinet 1. The door panel 5 can move back and forth along the Y-axis direction to achieve sealing and closure of the vacuum welding cabinet 1 and flexible closure 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 as an elastic connecting member 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.

[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, improve the welding quality, remove excess air from the battery body, and increase the battery cycle life.

[0074] After laser welding, the battery body is transferred to the fourth conveyor belt 27 by the gripping arm 9 of the battery gripping assembly. Then, the wiping mechanism 31 wipes the laser-welded battery body, and it is inspected by the post-weld monitoring mechanism 32. Battery bodies that pass the inspection are output, completing the battery body sealing nail welding process. The pre-weld monitoring mechanism 30, the in-weld monitoring mechanism 4, and the post-weld monitoring mechanism 32 can all be equipped with inspection units such as inspection cameras.

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