Description

Technical Field

[0001] The present invention relates to the field of electromagnetic pulse welding, and in particular to an adaptive pulse coil adjustment method based on electromagnetic pulse welding. Background Art

[0002] With the development of electronic information technology, the application scope of electromagnetic pulse welding technology has become increasingly extensive. Electromagnetic pulse welding is a solid-state welding process that can weld two workpieces together using magnetic force. Because electromagnetic pulse welding technology does not generate additional heat during welding and can complete high-quality welds of similar and dissimilar metals in a few microseconds, it is being used in an increasing number of precision welding applications.

[0003] However, current electromagnetic pulse welding equipment is often targeted at a product line of a fixed size, and the size of the electromagnetic pulse coil set inside is also single. If the material or size of the object to be welded changes, the pulse coil may have to be redesigned. This obviously does not take advantage of the demand for coils of various sizes in large-scale welding scenarios. Summary of the Invention

[0004] The purpose of the present invention is to provide an adaptive pulse coil adjustment method based on electromagnetic pulse welding, which can automatically adapt to the scheduling of electromagnetic pulse coils that meet the requirements according to the size of the welding area without replacing the electromagnetic pulse welding equipment, so that the electromagnetic pulse welding equipment can be suitable for more electromagnetic pulse welding scenario requirements.

[0005] The present invention solves the technical problem and adopts the following technical solution:

[0006] The adaptive pulse coil adjustment method based on electromagnetic pulse welding includes the following steps:

[0007] Electromagnetic pulse coils of various specifications and sizes are pre-set and stored inside the electromagnetic pulse welding equipment;

[0008] Obtain the size of the area to be welded, and call the electromagnetic pulse coil of corresponding size according to the size of the area to be welded;

[0009] The called electromagnetic pulse coil is controlled to move to the energy output port of the electromagnetic pulse welding equipment and correspond to the current area to be welded.

[0010] Furthermore, when electromagnetic pulse coils of multiple sizes are pre-set, the number of turns and winding direction of the electromagnetic pulse coils of the same size are the same, and each electromagnetic pulse coil has a connection node connected in series with other electromagnetic pulse coils of the same size.

[0011] Furthermore, electromagnetic pulse coils of the same size are stored in different areas inside the electromagnetic pulse welding equipment according to their size.

[0012] Furthermore, the size of the area to be welded is obtained by an image acquisition unit and / or a size input unit.

[0013] Furthermore, when the size of the area to be welded is obtained through the size input unit, the relevant parameters of the input size of the area to be welded are directly obtained;

[0014] When obtaining the size of the area to be welded by the image acquisition unit, the image of the area to be welded is first obtained by the image acquisition unit, and the outer frame of the area to be welded is delineated according to the image, and the size of the area to be welded is calculated according to the outer frame;

[0015] When the size of the area to be welded is obtained through the size input unit and the image acquisition unit, the relevant parameters of the size of the area to be welded directly obtained and entered are compared with the size of the area to be welded calculated based on the outer frame, and the final size of the welding area is determined after verification.

[0016] Furthermore, when calling an electromagnetic pulse coil of corresponding size according to the size of the area to be welded, it is determined whether an electromagnetic pulse coil of this size meets the current electromagnetic pulse welding conditions. If so, an electromagnetic pulse coil of this size is called; if not, two electromagnetic pulse coils of this size are called.

[0017] Furthermore, the current electromagnetic pulse welding condition refers to whether the number of turns of an electromagnetic pulse coil of a certain size meets the requirement.

[0018] Furthermore, when two electromagnetic pulse coils of the same size are called, the two electromagnetic pulse coils of the same size are connected in series using the connection node.

[0019] The beneficial effects of the present invention are as follows: through the above-mentioned adaptive pulse coil adjustment method based on electromagnetic pulse welding, first, electromagnetic pulse coils of various specifications and sizes are pre-set and stored within the electromagnetic pulse welding equipment. Secondly, the size of the area to be welded is obtained, and the electromagnetic pulse coil of the corresponding specification and size is called according to the size of the area to be welded. Then, the called electromagnetic pulse coil is controlled to move to the energy output port of the electromagnetic pulse welding equipment and correspond to the current area to be welded. The present invention can automatically adapt to the scheduling of the electromagnetic pulse coil that meets the requirements according to the size of the welding area, without the need to replace the electromagnetic pulse welding equipment, making the electromagnetic pulse welding equipment applicable to more electromagnetic pulse welding scenarios. For large-scale electromagnetic pulse welding scenarios, it will greatly improve the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 The figure is a flow chart of the adaptive pulse coil adjustment method based on electromagnetic pulse welding of the present invention. DETAILED DESCRIPTION

[0021] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0022] The present invention proposes an adaptive pulse coil adjustment method based on electromagnetic pulse welding, the flow chart of which is shown in FIG. Figure 1 , wherein the method comprises the following steps:

[0023] S1. Pre-set electromagnetic pulse coils of various sizes and specifications and store them inside the electromagnetic pulse welding equipment;

[0024] S2. Obtain the size of the area to be welded and call the electromagnetic pulse coil of the corresponding size according to the size of the area to be welded;

[0025] S3. Control the called electromagnetic pulse coil to move to the energy output port of the electromagnetic pulse welding equipment, and correspond to the current area to be welded.

[0026] In the above method, in order to adapt to the welding requirements of various sizes of objects to be welded in multiple scenarios, electromagnetic pulse coils of various sizes can be pre-set. In actual application, when electromagnetic pulse coils of various sizes are pre-set, the number of turns and winding direction of the electromagnetic pulse coils of the same size are the same, that is, the electromagnetic pulse coils of the same size are the same, which is specifically reflected in the number of coil turns and winding direction. Generally speaking, the coil material, density and diameter are the same. In addition, in order to meet the welding requirements when scheduling the electromagnetic pulse coils later, if more turns of electromagnetic pulse coils are required, at this time, each electromagnetic pulse coil has a connection node connected in series with other electromagnetic pulse coils of the same size, so as to form a series connection and increase the number of turns of the electromagnetic pulse coil.

[0027] It should be pointed out that when storing electromagnetic pulse coils, in order to ensure the convenience of subsequent scheduling, electromagnetic pulse coils of the same specifications and dimensions need to be stored in different areas inside the electromagnetic pulse welding equipment according to the specifications and dimensions.

[0028] During actual application, the size of the area to be welded can be obtained through the image acquisition unit and / or the size input unit.

[0029] When the size of the area to be welded is obtained through the size entry unit, the relevant parameters of the size of the area to be welded are directly obtained; the size entry unit here can use the human-machine interface of the electromagnetic pulse welding equipment, or a separate entry terminal can be set up. Before using the entry terminal to enter the relevant parameters of the size of the area to be welded, it is necessary to establish a communication connection between the entry terminal and the electromagnetic pulse welding equipment.

[0030] When the size of the area to be welded is obtained through the image acquisition unit, the image of the area to be welded is first obtained by using the image acquisition unit, and the outer frame of the area to be welded is delineated based on the image, and the size of the area to be welded is calculated based on the outer frame; here, the image acquisition unit can use one or more groups of cameras, with the ability to capture a clear image of the area to be welded as a benchmark.

[0031] When the size of the area to be welded is obtained through the size entry unit and the image acquisition unit, the relevant parameters of the size of the area to be welded directly obtained and entered are compared with the size of the area to be welded calculated based on the outer frame, and the final size of the welding area is determined after verification. The verification here can be done manually or by pre-setting the verification standard and verifying it according to the verification standard to finally obtain the accurate size of the area to be welded.

[0032] It should be noted that when calling an EMP coil of a corresponding size based on the size of the area to be welded, a determination is made as to whether a single EMP coil of that size meets the current EMP welding conditions. If so, a single EMP coil of that size is called; if not, two EMP coils of that size are called. Here, the current EMP welding conditions refer to whether the number of turns of a single EMP coil of that size meets the requirements.

[0033] Generally speaking, if the size of the called electromagnetic pulse coil meets the requirements, if the material of the object to be welded changes and more turns of electromagnetic pulse coils of this size are required, they can be directly connected in series using the connection node, that is: when two electromagnetic pulse coils of this specification size are called, the two electromagnetic pulse coils of this specification size are connected in series using the connection node to meet the welding requirements of more welding objects and more welding scenarios.
