Description

Technical Field

[0001] The invention relates to the technical field of plasma arc welding, and in particular to a semiconductor tube shell welding packaging device. Background Art

[0002] With the continuous development of modern electronic technology and information technology, smart electronic devices are appearing more and more in people's lives, semiconductor chips are being used more and more frequently, and their importance in electronic devices is increasing day by day, with broad application prospects; semiconductor chips need to be packaged and the leads welded during the production process, and corresponding calibration needs to be performed before welding to ensure the accuracy of lead welding of semiconductor chips.

[0003] Plasma arc welding technology is a highly efficient welding method. Its principle is to use a special welding gun to ionize the incoming gas to produce a high-temperature and high-energy density plasma arc. The arc temperature can reach tens of thousands of degrees Celsius. Through the transferred plasma arc, the current is allowed to act on the weldment through electrodes, plasma gas, etc. to achieve welding. It has concentrated energy and high temperature, and can perform deep penetration welding on thicker metals. The weld has a deep penetration and excellent quality. There are also non-transferred plasma arcs and other types, which are suitable for a variety of materials and welding scenarios. It is widely used in aerospace, automobile manufacturing and other fields, and can meet the needs of high-precision and high-quality welding, and improve the overall performance of the product.

[0004] The existing Chinese patent with publication number CN211387466U discloses a welding auxiliary device for the production and processing of semiconductor package integrated blocks. The user first places the semiconductor integrated block on a placement plate, and then rotates the rotating disk to move the rotating disk upward. In contact with the two swing rods, the bottom ends of the two swing rods swing outward, and the top ends of the two swing rods swing toward each other, thereby driving the two clamping blocks to clamp and fix the semiconductor integrated block, thereby facilitating the welding of the semiconductor integrated block.

[0005] The existing Chinese patent with publication number CN208276423U discloses a welding auxiliary device for the production and processing of semiconductor packaging integrated blocks, which can adjust the height of two groups of brackets through two groups of bolts. When adjusting, it is only necessary to unscrew the bolt to the left through the screw ear, and the right end of the bolt is drilled out from the limit hole on the right, the through hole and the limit hole on the left in turn, thereby facilitating the longitudinal movement of the plug. After adjustment, it is only necessary to screw the bolt to the right through the screw ear, and the right end of the bolt is drilled out from the limit hole on the left, one of the through holes in multiple groups of through holes and the limit hole on the right in turn and screwed to the nut to achieve a fixing effect, so that the height of the work plate can be conveniently adjusted according to the needs of the staff.

[0006] However, the above device has the following problems:

[0007] 1. When welding the semiconductor shell, it is necessary to manually fix the semiconductor shell and the parts to be welded on the device. Since the semiconductor welding precision is high, manual operation is prone to errors, resulting in cold welding and increasing material loss. At the same time, manual placement of the semiconductor shell and the parts to be welded requires a lot of time for fixing and disassembling, which greatly reduces the working efficiency of the device;

[0008] 2. In the prior art, when welding the semiconductor shell through mechanical assembly line operation, since the semiconductor shell and the component to be welded often need to be connected by multiple leads, the welding gun or the semiconductor needs to be rotated multiple times during welding. During the rotation process, the welding gun continuously welds the pin position of the semiconductor. When the welding head performs the welding operation on the shell, a certain force will be applied. These forces may push the shell during the welding process, causing it to shift or tilt on the welding platform, causing the shell to gradually deviate from the predetermined welding position, resulting in the phenomenon of cold welding, which greatly reduces the working efficiency of the device.

[0009] Therefore, a semiconductor tube shell welding packaging device is needed to solve this problem. Summary of the invention

When the welding head performs the welding operation on the tube shell, a certain force will be applied. These forces may push the tube shell during the welding process, causing it to shift or tilt on the welding platform, causing the tube shell to gradually deviate from the predetermined welding position, resulting in the phenomenon of cold welding.

When the starting device performs welding and packaging on the semiconductor tube shell, the unloading device is started to make the welding component fall into the interior of the welding frame, and a semiconductor tube shell placing device is arranged between the unloading device and the welding device. At the same time, the electric telescopic rod is started, and the electric telescopic rod presses the hot pressing welder downward, and at the same time, the T-shaped connecting rod moves downward, thereby driving the two groups of extrusion rods to slowly squeeze the extrusion groove on the connecting piece downward. When the extrusion rod slowly squeezes the connecting piece, since the electric telescopic rod is still moving downward, the conveyor belt is driven to move forward, and the extrusion rod slowly rotates in the connecting piece until it becomes a vertical state. At this time, the welding frame is displaced under the action of the conveyor belt, and the welding frame of the latter section is conveyed to the lower end of the hot pressing welder.

The electric telescopic rod presses the hot pressing welder downward, and at the same time makes the T-shaped connecting rod move downward, thereby driving two groups of extrusion rods to slowly squeeze the extrusion groove on the connecting piece downward. When the extrusion rod slowly extrudes the connecting piece, since the electric telescopic rod is still moving downward, the conveyor belt is driven to move forward, and the extrusion rod slowly rotates in the connecting piece until it becomes a vertical state. At this time, the welding frame is displaced under the action of the conveyor belt, and the welding frame of the rear section is conveyed to the lower end of the hot pressing welder. At the same time, the extrusion rod fixes the connecting piece, so that the conveyor belt maintains a stable state, and the welding components in the welding frame are welded. When the present invention is welding the components to be welded, the conveyor belt can be stably conveyed by the extrusion rod, and the process of sequential feeding is completed by the extrusion rod.
