Description

Technical Field

[0001] The invention relates to the technical field of wiring terminal processing, in particular to automatic welding equipment for wiring terminal processing. Background Art

[0002] When processing terminal blocks, it is necessary to connect the wires and terminals and cooperate with corresponding welding settings to improve the stability of the wiring. In mass production, automatic welding equipment can be effectively used to improve welding efficiency and production efficiency. During use, it is inconvenient to effectively and quickly connect terminals and lines, which affects the efficiency of automatic welding.

[0003] In order to overcome the above-mentioned defects, the prior art (Chinese patent application with application number CN202420638603.3 and application date 2024-03-29) provides a moving busbar welding device. Compared with the prior art, the moving busbar output position can be adjusted and matched by setting a second slide rail, a second slide seat, a second screw rod, a second motor, an electric telescopic rod and a drag ring. At the same time, the height of the moving busbar can be adjusted according to the height of the welding head inside the welding assembly, thereby avoiding the situation where the moving busbar is subjected to excessive force and is separated from the welding assembly. At the same time, it also avoids the falling of the moving busbar, thereby reducing the tension and friction on the moving busbar, thereby increasing the service life of the moving busbar, avoiding the need for maintenance, and thus improving welding efficiency; there is also a prior art (application number CN202411603609.8, Chinese patent application date 2024-11-12) battery terminal automatic welding device, which first presses the terminal with a pressure plate, and then when the clamping block adjusts the angle and position of the battery, the support block and the pressure plate are moved synchronously with the battery, so that the terminal can always maintain contact with the battery. The relative position remains unchanged, which changes the existing way in which the clamping block can only position the battery, and can reduce the risk of the terminal tilting or moving on the battery, which is beneficial to improving the welding effect. At the same time, in the present application, the clamping block first adjusts the position of the battery before pushing the battery to abut against the frame, thereby reducing the risk of damage caused by contact with the frame when the battery is deflected, which is beneficial to ensuring the life of the battery; and the prior art (application number CN201620324796.0, Chinese patent application application date 2016-04-18) a welding device for terminal blocks, which uses high-frequency induction welding to not only eliminate the use of welding wire but also improve the welding quality and welding efficiency. During welding, the cylinder controls the welding gun on the slider to move up and down to weld the terminal blocks one by one; although the prior art can complete the limited docking, the clamping piece used for positioning during the terminal loading process is not convenient for controlling the position accuracy of the terminal during loading, affecting the safety of the welding mechanism, and because the welding head directly contacts the terminal and the line, it is very easy to cause excessive squeezing between the terminal and the line, resulting in easy breakage of the weld.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original automatic welding equipment for terminal processing. Summary of the Invention

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic welding device for processing terminal blocks, provided with a welding bracket for positioning support, and a loading mechanism is installed on the left side of the welding bracket, and a welding mechanism is connected to the right side of the loading mechanism; comprising: a base, installed on the lower surface of the welding bracket, and a support seat is telescopically provided on the upper side of the inner surface of the base, and a turntable is rotated on the right side of the support seat, and the upper surface of the turntable is connected to a connecting rod through an eccentric axis, and a positioning shaft is rotated on the left side of the connecting rod, and a clamping frame is installed on the upper surface of the positioning shaft, and the clamping frame is provided with a limited clamping mechanism; a welding jig is connected to the front side of the upper surface of the support seat, and the upper surface of the welding jig supports the terminal body, and the welding jig is provided with an embedded positioning mechanism.

[0008] Through the above structure, the position of the clamping frame can be controlled during use, so that the clamping frame can control the clamp to load the terminal, thereby staggering the terminal with the welding mechanism to avoid damage to the welding mechanism.

[0020] With the above structure, the stability of the welding fixture's position limitation is controlled by the rotatably connected positioning piece, and the positioning piece and the nesting seat with the tapered surface during use.

[0021] Preferably, the inner surface of the base is rotatably connected to a bevel gear set, and the bevel gear set is connected to gear three through a rotating shaft, and the outer surface of gear three is meshedly connected to a lifting column, and at the same time, the upper side of the inner surface of the lifting column is telescopically connected to telescopic column one, and telescopic column one is nested and slid on the inner surface of the base, and a lifting spring is elastically connected between telescopic column one and the base, and telescopic column one is installed on the lower surface of the support seat, and telescopic column two is installed in the middle section of the lower surface of the support seat, and telescopic column two is nested and slid in the middle section of the inner surface of the base.

[0022] Through the above structure, when in use, the lifting columns in different positions can be linked and controlled to adjust their positions through the symmetrically arranged bevel gear set and gear three, thereby adjusting the elastic buffering force between the base and the support seat, increasing the safety and stability during welding, and avoiding excessive extrusion welding.
