Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing equipment technology, and in particular to a capacitor welding and flipping device based on a semi-automatic electric arc. Background Technology

[0002] As a core energy storage component in electronic devices, capacitors are widely used in power systems, industrial frequency converters, and new energy vehicle charging piles, among other fields. Their welding quality directly determines product reliability and lifespan. In semi-automatic arc welding processes, capacitor casings need to be flipped and positioned to enable welding operations on different sides, meeting production requirements. Currently, existing capacitor welding flipping methods rely heavily on manual operation or complex automated equipment. Manual flipping is not only labor-intensive and inefficient, but also poses safety risks due to the high temperatures after welding. Furthermore, operational errors can easily lead to capacitor positioning misalignment and inaccurate flipping angles, resulting in defects such as incomplete welds and welding misalignments, affecting product yield. Complex automated equipment, on the other hand, suffers from high production costs, cumbersome installation, and inconvenient maintenance, and is difficult to adapt to the flipping requirements of capacitors of different sizes, exhibiting poor flexibility. Simultaneously, existing flipping devices generally lack reliable braking and positioning mechanisms, leading to angular deviations after flipping and insufficient positioning accuracy, failing to reliably meet the precise positioning requirements of semi-automatic arc welding. In addition, the adaptability and stability of the clamping mechanisms are poor, easily damaging the capacitor casing, further restricting the efficiency and quality of capacitor welding and making it difficult to meet the actual needs of mass production.

There are two positioning grooves 934, which are respectively opened at the upper and lower positions of the right side of the telescopic arm 85. The interior of the positioning groove 934 matches the left exterior of the positioning head 933 and is hemispherical.

[0033] The workbench 10 is provided with several welding limiting grooves.

[0034] The invention is used in the following way: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, first, the motor 21 of the lifting mechanism 2 is started. The output shaft of the motor 21 drives the screw 22 to rotate clockwise. The screw 22 is threadedly engaged with the nut seat 23, driving the nut seat 23 to move the lifting seat 5 vertically downwards along the guide groove 4. Simultaneously, the lifting seat 5 drives the telescopic transmission device 8 and the positioning clamp 9 on the right side to move downwards together until the snap-fit ​​hole 92 of the positioning clamp 9 is fitted onto the outside of the capacitor shell to be clamped. At the same time, the spring 99 pushes the movable clamp 94 to move towards the capacitor shell, cooperating with the fixed clamp 910 to clamp and fix the capacitor shell. At this time, the positioning chuck 933 of the positioning structure 93 is still inserted in the positioning groove 934 to ensure that the positioning chuck 9 will not rotate arbitrarily. After clamping is completed, the motor 21 is started again. The output shaft of the motor 21 drives the screw 22 to rotate counterclockwise, which drives the nut seat 23 to move the lifting seat 5 vertically upward along the guide groove 4. The lifting seat 5 synchronously drives the telescopic transmission device 8, the positioning chuck 9 and the clamped capacitor shell to move upward together. As the lifting seat 5 moves upward, the transmission gear 64 of the flipping mechanism 6 gradually meshes with the fixed rack 66 on the rear side of the inner groove 61. Since the transmission gear 64 is connected to the transmission shaft 65 through a one-way bearing, the transmission gear 64 rotates under the action of the fixed rack 66 during the upward movement of the lifting seat 5, and drives the transmission shaft 65 to rotate synchronously through the one-way bearing.The drive shaft 65 drives the drive shaft 74 of the brake holding mechanism 7 connected to its right side to rotate. The rotation of the drive shaft 74 drives the connecting shaft 81 to rotate through the connector 75. The connecting shaft 81 then drives the positioning chuck 9 to rotate and flip as a whole through the spline hole 83, spline shaft 89 and rotating head 88. When the drive gear 64 moves upward and disengages from the fixed rack 66, the spring 78 can cause the push slot block 76 to lock the rotating body 73 for braking. In addition, the positioning chuck 933 of the positioning structure 93 is always locked in the positioning groove 934. Together with the brake holding mechanism 7, this double protection ensures that the capacitor shell remains at a fixed angle after flipping, meeting the requirements of welding operations. During the upward movement of the lifting seat 5, the positioning block 63 also moves synchronously with the drive shaft 65 and flips. After the capacitor shell has flipped, the motor 21 is started. The output shaft of the motor 21 drives the screw 22 to rotate clockwise, driving the lifting seat 5 to move vertically downward along the guide groove 4. At this time, due to the transmission... The shaft 65 and the transmission gear 64 are connected by a one-way bearing. When the transmission gear 64 meshes and rotates with the fixed rack 66, it will not drive the transmission shaft 65 to rotate. Therefore, the angle of the capacitor shell after flipping remains unchanged. As the lifting seat 5 continues to move downward, the positioning block 63 will precisely engage in the positioning groove on the upper side of the positioning slot seat 62, further improving the positioning accuracy of the capacitor shell after flipping and preventing it from shifting or rotating. When the lifting seat 5 continues to move downward until the capacitor shell held by the positioning chuck 9 moves down to above the worktable 10 and aligns with one of the welding limit grooves on the worktable 10, the operator will then pull the movable handle 97 again. This will cause the movable chuck 94 to compress the spring 99 through the connecting rod 98, separating the movable chuck 94 from the capacitor shell and releasing the clamp on the capacitor shell. Under the action of gravity, the capacitor shell will fall completely into the welding limit groove of the worktable 10, completing the placement and positioning of the capacitor shell, which will facilitate subsequent semi-automatic arc welding operations.
