[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] The utility model provides two technical solutions:

[0024] Figures 1-5The first embodiment is shown: a new energy motor lead-out line servo square welding machine, including the workbench 1, the workbench 1 top near the front side position is equipped with the lower electrode square pressing mechanism 2, the workbench 1 top near the rear side position is equipped with the installation rack mechanism 3, the installation rack mechanism 3 front side is equipped with the servo lifting welding mechanism 4;The lower electrode square pressing mechanism 2 includes the lower electrode fixed plate 21 installed on the top surface of the workbench 1, the lower electrode fixed plate 21 top near the rear side position is installed with the cylinder fixed seat 22, the cylinder fixed seat 22 top is installed with the cylinder 23, the cylinder 23 telescopic end is installed with the linear guide rail sliding block 24, and the linear guide rail sliding block 24 is slidably connected with the cylinder fixed seat 22 through the slide rail, and the linear guide rail sliding block 24 top is installed with the square pressing block 25;The servo lifting welding mechanism 4 includes the upper bottom plate 41, and the upper bottom plate 41 is L-shaped structure, the upper bottom plate 41 top is installed with the servo motor 42, the servo motor 42 output shaft end moves through the upper bottom plate 41 top surface and extends downward, the servo motor 42 output shaft end is installed with the ball screw 43, the ball screw 43 is threaded on the upper electrode seat 44, the upper electrode seat 44 bottom is installed with the upper electrode 47, and the upper electrode 47 is placed above the square pressing block 25, the lower electrode fixed plate 21 top near the front side position is installed with the lower electrode fixed block 26, the lower electrode fixed block 26 top is installed with the lower electrode 27, and the lower electrode 27 is on the same horizontal plane with the square pressing block 25.

[0025] Specifically, first, the servo motor 42 has torque mode and displacement mode, which cooperates with the ball screw 43 to form an accurate vertical motion control system. In torque mode, the servo motor 42 can provide stable torque output to ensure that the ball screw 43 can bear a certain load when rotating. In displacement mode, the rotation angle of the ball screw 43 can be accurately controlled, so that the vertical displacement of the upper electrode seat 44 and the upper electrode 47 can be accurately controlled. When the servo motor 42 drives the ball screw 43 to rotate, the upper electrode seat 44 is threaded on the ball screw 43, and according to the lead and rotation angle of the ball screw 43, the upper electrode seat 44 will produce accurate vertical linear motion. This accurate vertical motion can achieve high-precision control of the position of the upper electrode 47, and further achieve precise control of the up-down welding pressure. At the same time, according to the requirements of materials and processes, the welding deformation can be accurately controlled by controlling the depth and speed of the upper electrode 47, so as to ensure the welding quality.

[0029] In this embodiment, the front surface of the upper electrode seat 44 is provided with an upper cover plate 45, the upper cover plate 45 is a U-shaped structure, the rear surface of the upper cover plate 45 is located at the left and right side edges and is slidably connected to the front surface of the upper bottom plate 41 through a slide rail and a sliding block, and a displacement sensor 46 is arranged on the surface of the upper cover plate 45 near the right side edge.

[0030] Specifically, the displacement sensor 46 is used to monitor the displacement of the upper electrode seat 44 to more accurately control the electrode position during welding.

[0031] In this embodiment, the left surface of the workbench 1 is provided with a welding controller 11, a water distributor 12, a pneumatic three-way piece 13 and an electromagnetic valve group 14, and the welding controller 11 is electrically connected to the transformer 34.

[0032] Specifically, the welding controller 11 is used to control the parameters of the entire welding process, such as current, voltage, welding time, etc., the pneumatic three-way piece 13 provides gas source processing and control for pneumatic components such as the air cylinder 23, the electromagnetic valve group 14 can control the on-off of the air path of components such as the air cylinder 23, and the water distributor 12 can dry the compressed air and perform other processing to prevent water from affecting the equipment.

According to the welding requirements, set the required welding parameters such as welding current, voltage, time, and the pressing distance of the upper electrode 47 through the welding controller 11, then the welding controller 11 controls the servo motor 42 to start, and the servo motor 42 enters the torque mode and displacement mode according to the set parameters, drives the ball screw 43 to rotate, drives the upper electrode seat 44 and the upper electrode 47 on it to move downward, and makes the upper electrode 47 close to the lead-out wire and terminal placed on the pressing block 25.

[0035] At the same time, the cylinder 23 extends and pushes the linear guide rail slider 24 and the pressing block 25 to move forward to limit the lead-out wire and terminal from front to back. When the upper electrode 47 and the lower electrode 27 contact the lead-out wire and terminal, the welding controller 11 controls the transformer 34 to start discharging to apply electric energy to the upper and lower electrodes, and uses the welding principle of resistance heat or arc heat to weld the lead-out wire and terminal together.

[0036] After completing the welding operation, the welding controller 11 controls the servo motor 42 to reverse, so that the upper electrode 47 is lifted upward, and at the same time the cylinder 23 is retracted to reset the pressing block 25, completing a complete welding operation. Through the accurate control and front and back limiting of the upper and lower electrodes in the whole process, the precision and quality of the welding are ensured, the production efficiency and the product qualification rate are improved, and the welding requirements of different specifications of new energy motor lead-out wires are met.
