Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically relates to a welding equipment for pins of a ceramic heating element. Background Art

[0002] A ceramic heating element is a medium that can make a heating wire generate heat after being powered on. Ceramic heating elements are widely used in life. For example, they are used in atomizers, especially as ceramic heating cores in electronic cigarette atomizers. During the production process of ceramic heating elements, corresponding welding equipment is required to weld the pins at both ends of the ceramic heating element. After retrieval, a patent with the Chinese patent publication number CN216298217U discloses a welding equipment for pins of a ceramic heating element, which includes a frame, a pin feeding device and a folding foot testing device on the frame. The pin feeding device includes a feeding and cutting chuck and a welding chuck. The welding chuck is located on the side of the feeding and cutting chuck for feeding pins. The feeding and cutting chuck is arranged on a feeding and cutting slide seat, and the feeding and cutting slide seat is driven by a feeding and cutting slide seat cylinder to slide back and forth towards the spot welding table. Although this technical solution can automatically weld and bend the pins of the ceramic heating element, when in use, there is only one processing station. Therefore, after each processing, the operations of unloading and loading materials need to be carried out, and continuous processing cannot be carried out, thus reducing the work efficiency. Moreover, when in use, each structure is fixed and cannot be adjusted, which is inconvenient for welding ceramic heating elements of different specifications, and the cutting length of the pins cannot be adjusted.

[0003] A patent with the Chinese patent publication number CN218465706U discloses a flat welder for ceramic pins, which includes a unit platform and a ceramic feeding device, a pin conveying device, a ceramic positioning device, and a ceramic output device arranged on the unit platform; the ceramic feeding device includes a feeding module and a clamping cylinder, and the feeding module includes a vibration motor, a vibration disc, and a vibration discharging port. Although this technical solution can also realize automatic pin welding of ceramic heating elements, there is also only one processing station, which will also reduce the work efficiency.

[0006] The adjustable conveying mechanism includes a chute formed on the upper surface of the base. Two first side plates are symmetrically and slidably connected to the upper surface of the base. A belt conveyor is fixedly installed on the outer surface of each first side plate. On one side of the outer surface of the belts of the two belt conveyors, a plurality of mounting frames are sequentially fixedly connected. A placing frame for placing a ceramic heating element is provided between two opposite mounting frames.

[0007] Through the above technical solution, the provided placing frame facilitates the placement of the corresponding ceramic heating element. The operation of the belt conveyor can directly convey the ceramic heating element, thereby improving work efficiency. Moreover, the placing frame connected by bolts is convenient for replacement, thus facilitating the conveyance of ceramic heating elements of different specifications.

The top end of the slider is fixedly connected to the bottom end of the adjacent first side plate. An L-shaped blanking plate is fixedly connected to one side of each of the two first side plates.

[0009] Through the above technical solution, the rotation of the first motor drives the rotation of the first bidirectional lead screw.

A fifth cylinder is fixedly installed through one side of the top of the moving plate. The bottom end of the fifth cylinder is fixedly connected to a pressing plate for pressing the pin wire.

[0017] Through the above technical solution, the rotation of the second motor drives the rotation of the second bidirectional lead screw, and the two moving blocks and the welding gun can be driven to move left and right through the thread, so as to facilitate the pin welding of ceramic heating elements of different specifications. The operation of the fifth cylinder can drive the pressing plate to move downward, and then the two pins can be pressed tightly to avoid movement during welding, thereby improving the welding quality.

[0018] Preferably, the adjustable feeding mechanism includes a support seat fixedly connected to one side of the top of the base. Mounting frames are symmetrically fixedly connected to the top of the support seat. A winding roller is rotatably connected inside the mounting frame. A pin wire is wound around the outer surface of the winding roller. Straighteners are sleeved on the outer surfaces of the two pin wires.

[0019] Through the above technical solution, the two straighteners can automatically convey and straighten the two pin wires.

[0020] Preferably, a sixth cylinder is fixedly installed on the outer surface of the first side plate located on one side.
