Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a multi-type welding structure. Background Technology

[0002] Spot welding is a welding process that uses resistance heat generated by electric current to locally melt metal and form a connection through pressure. The steps are usually as follows: In the pressurization stage, the electrode applies a predetermined pressure to the workpiece to make the workpieces to be welded in close contact, eliminate gaps, and form a stable current path. In the welding heating stage, the welding current is turned on to form a circuit. Resistance heat melts the metal in the contact area to form a weld nugget. In the pressure holding stage, after the current is cut off, the electrode continues to maintain pressure, allowing the weld nugget to cool and solidify under pressure. In the rest stage, the electrode releases pressure and leaves the workpiece, completing the welding of one spot and preparing for the next cycle.

[0003] Chinese patent CN219443808U discloses a spot welding device, including a frame, an upper spot welding head and a lower spot welding head disposed on the frame, and a worktable disposed on the frame. The worktable has a welding area located at the positions of the upper and lower spot welding heads. The worktable is provided with an adjustment component for fixing the position of the workpiece. The adjustment component includes a first guide rail, a clamping block, and a connecting rod. The first guide rail is fixed to the worktable, and part of it is located in the welding area. The clamping block is movably disposed on the first guide rail. A left clamping block is located on the left side, and a right clamping block is movably located on the right side of the first guide rail. The connecting rod connects the left clamping block and the right clamping block. The left clamping block and the right clamping block are respectively provided with locking members. As the locking members abut against the connecting rod, they are used to fix the relative distance between the left clamping block and the right clamping block. The left clamping block and the right clamping block are respectively provided with second guide rails, and fixed seats are movably mounted on the left clamping block and the right clamping block through the second guide rails. The workpiece is placed on the fixed seat, and the welding position of the workpiece in the welding area is adjusted as the fixed seat and the clamping block move.

[0004] However, the technical solution of this patent has the following problems: This patent cannot perform multiple types of welding and fusion, nor can it automatically lock the gap during continuous welding.

[0005] Therefore, those skilled in the art have provided a multi-type welding structure to solve the above problems. Utility Model Content

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A multi-type welding machine includes a frame 1, a fixing fixture mechanism 2 for fixing circuit boards is installed on the frame 1, a clamping mechanism 3 for clamping the solder joints of the circuit board and assisting in welding is installed on the middle side of the frame 1, a pressing mechanism 4 for pressing the circuit board and assisting in welding is installed on the right front side of the frame 1, and a continuous welding mechanism 5 for continuously spot welding the clamped or pressed circuit board is installed on the left front side of the frame 1.

The fixed ends of multiple hydraulic buffers 44 are fixedly installed at the output end of the first robotic arm 41, and the buffer ends of the hydraulic buffers 44 are close to the end of the irregularly shaped sliding frame 42 away from the voltage conductive block 43.

[0017] The output end of the first mechanical arm 41 of the first drive component of the pressing mechanism 4 moves, driving the voltage-conducting block 43 on the irregular sliding frame 42 to the second welding point 24. The output end of the first mechanical arm 41 moves downward, driving the irregular sliding frame 42 and the voltage-conducting block 43 downward. The voltage-conducting block 43 moves downward and abuts against the second welding point 24. At the same time, the irregular sliding frame 42 moves upward due to the reaction force of the voltage-conducting block 43. The hydraulic buffer 44 buffers the movement of the irregular sliding frame 42 and keeps the irregular sliding frame 42 under continuous pressure, so that the voltage-conducting block 43 always abuts against the second welding point 24, which is beneficial to the stability of subsequent welding fusion.

The output end of the third robotic arm 51 of the welding component moves, driving the sliding support frame 52 and the conductive rod 54 to move above the first welding point 23 or the second welding point 24. The output end of the fourth cylinder 53 moves, driving the sliding support frame 52 and the conductive rod 54 to move downward, so that the conductive rod 54 is close to the first welding point 23 or the second welding point 24.
