Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a copper bottom plate welding device. Background Art

[0002] Copper base plate is a circuit board material composed of copper foil and substrate, usually used as the base plate of PCB board. Its material is mainly pure copper or copper alloy with copper content of more than 99.99%. Copper base plate is mainly produced by die casting or stretching. Die casting is generally to place pure copper or copper alloy billet in a mold and form it under high temperature and high pressure; stretching is to stretch the copper foil into the shape of the base plate.

[0003] Copper baseplate is widely used in the electronics industry. It is mainly used as the base plate of PCB board. Its biggest advantage is that it has excellent conductivity and can quickly transmit electrical signals. In addition, copper baseplate can also provide strong mechanical support to help maintain the shape and stability of the circuit board.

[0004] In addition, copper baseplates also play a very important role in some high-performance applications. For example, in some high-speed and high-frequency circuits, since electrical signals need to be transmitted quickly and stably, the uniformity and thinness of the copper baseplate are very important. In addition, for some high-temperature applications, the thermal conductivity of pure copper baseplates is very good, so they are often used as heat sinks.

[0005] Various parts usually need to be welded on the copper base plate to meet its use or assembly performance. During the welding operation, it is usually necessary to use a welding fixture to clamp and fix the workpiece to be welded to ensure its welding accuracy. The traditional welding fixture only has the function of clamping and fixing. After welding is completed, the workpiece outside the welded city needs to be manually pulled out, which is troublesome to remove. In addition, the welding slag is easy to scatter and accumulate on the fixture, which is troublesome to clean and even affects the positioning accuracy of the fixture. Utility Model Content

[0029] The use of the utility model:

[0030] First of all, it should be made clear that the welding device involved in the utility model is mainly used for welding operations on flat parts of plate materials. The utility model takes the automatic lifting of the welded workpiece and the collection and cleaning of welding slag during the welding process of the copper bottom plate as an example to explain its use method in detail. The welding process can be divided into two situations. One is full automation, that is, the automatic conveying of materials is realized by a vibrating feeding plate in conjunction with a mobile platform, the automatic placement and removal of the welded workpiece is realized by a manipulator, and the welding operation of the welded part is realized by an automatic welding gun. The second is manual loading and unloading, automatic welding is realized with the help of a manipulator, and manual material removal is performed after welding is completed. Both methods can be used for the automatic lifting and welding slag collection operations involved in the utility model. When the welded workpiece needs to be removed after welding is completed, the clamping part of the clamp 400 is released, and the output rod of the telescopic push rod 601 is started to extend, and the push plate 602 and The collecting mechanism 700 lifts the workpiece on the fixture 400 after welding, and then cooperates with the automatic material taking mechanism or manual work to take out the workpiece after welding.

The utility model can realize automatic lifting of the welded workpiece through the ejection mechanism 600, which is convenient for subsequent operators or automatic material taking mechanisms to take out materials, and the welding slag in the welding process can be collected in a centralized manner through the collecting mechanism 700 to prevent it from being scattered on the fixture 400, causing trouble in subsequent cleaning, and even causing the positioning accuracy of the fixture 400 to deteriorate in severe cases. Cleaning is more convenient and simple, which solves the problem that the traditional welding fixture 400 cannot automatically lift the welded material, which makes it more troublesome to take out the workpiece, and the welding slag is easily scattered and accumulated on the fixture 400, which is troublesome to clean and even affects the positioning accuracy of the fixture 400.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
