The bottom end of the welding head fixing plate 38 is installed with a welding head 39, and the top end is detachably provided with a plurality of counterweights 310.

[0033] During welding, the material base is placed in the base tray component, and the material cover is transferred from the cover tray component by the cover transfer component. The welding heads on the left and right sides are respectively installed on the welding head fixing plates on the left and right sides. According to the size of the welding material, the first servo motor drives the welding head on the bidirectional lead screw to move left and right synchronously, thereby accurately realizing the welding of materials of different sizes. The first up and down moving module is driven by the second servo motor to drive the left welding component and the right welding component to move up and down. After welding a material, the entire roller welding component is driven to rise, and the material chassis moves to the next material station. At this time, the cover transfer component transfers the cover to the new material base.

[0035] The base tray component is placed under the roller welding component. Its main function is to place the base of the welding material in the base tray. It has two linear motion axes, X, Y and R, and one rotational motion axis around the Z axis. The horizontal left and right movement in the X direction is achieved by the fourth servo motor driving the first left and right movement module, the horizontal forward and backward movement in the Y direction is achieved by the third servo motor driving the first forward and backward movement module, and the R rotation is driven by the fifth servo motor to drive the turntable drive module to achieve left and right movement, thereby driving the rotary alignment platform to rotate around the Z axis, and the direct drive torque motor rotates 90° to achieve welding of square materials in two directions.

[0036] When welding a pair of sides of a rectangular material, the third servo motor drives the first forward and backward moving module to move horizontally. After welding one material, the third servo motor drives the first forward and backward moving module, and the fourth servo motor drives the first left and right moving module to move horizontally to the second material position for welding; when the other set of opposite sides of the rectangular material needs to be welded, the direct drive torque motor rotates 90° to weld in sequence; when the horizontal angle of the material needs to be adjusted, the fifth servo motor drives the turntable drive module to move horizontally left and right, and then drives the rotary alignment platform to rotate and align to adjust the accurate posture of the material to ensure welding accuracy.

[0038] The main function of the cover plate transfer component is to accurately transfer the material cover plate from the cover plate tray to the corresponding material base on the base tray.

[0039] First, the ninth servo motor drives the second forward and backward moving module, and the ninth servo motor drives the second left and right moving module to move horizontally above the cover to be moved. Then the eighth servo motor drives the second up and down moving module to move the nozzle down to the cover to be moved. At the same time, the nozzle sucks the cover. The eighth servo motor drives the second up and down moving module to move the nozzle up to the specified height. The cover on the nozzle is placed on the corresponding material base by driving the second forward and backward moving module, the second left and right moving module, and the second up and down moving module. During the transfer process, it passes through the upward visual component, and the upward visual component visually recognizes its posture and gives feedback. If it exceeds the allowable error, the sixth servo motor drives the pneumatic rotary joint to rotate and adjust to a reasonable posture. After the transfer is completed, the roller welding head performs spot welding, and the eighth servo motor drives the second up and down moving module again to move the nozzle up and transfer the next cover. The characteristics of this cover transfer component are accurate moving position, fast transfer speed, and high alignment accuracy.

[0041] This component can meet the needs of different working conditions. It can be used alone as a fixed cover tray or a clip cover tray. The clip cover tray has two linear motion axes, X and Z. The horizontal left and right movement in the X direction is achieved by the eleventh servo motor driving the third left and right moving module, and the vertical up and down movement in the Z direction is achieved by the tenth servo motor driving the up and down moving synchronous belt.
