Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of computer storage medium, may include therein a network communication module, a user interface module, and a welding program between sheets.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to invoke a welding program between the sheets stored in the memory 1005 and perform the following operations:

and obtaining cosine line parameters input by a user, and determining the cosine line according to the cosine line parameters.
Referring to fig. 2, in one embodiment, a welding method between sheets includes the steps of:
step S10, obtaining a path to be welded;
in this embodiment, the path to be welded may be a welding path preset in the upper computer, or may be a welding path input by an operator to the upper computer according to an actual requirement, so as to control welding between the plates by the upper computer.
Alternatively, the path to be welded may be a path of various shapes, and for example, a path in which a spiral line shown in fig. 4 is present may be taken as the path to be welded. Alternatively, the spiral may be an archimedean spiral, a fermat spiral, an equiangular spiral, or the like.
Step S20, overlapping the path to be welded by a sine line or a cosine line to obtain an overlapped path, wherein the length of the overlapped path is greater than that of the path to be welded;
in this embodiment, because the function values corresponding to the sine line and the cosine line are periodically changed in a certain value range, the paths to be welded are overlapped by using the sine line or the cosine line, the obtained paths after the overlapping processing do not exceed the original welding area, but the length of the welding path is increased, so that the welding bonding force between the plates is increased.
Optionally, when the paths to be welded are superimposed by using sine lines or cosine lines, a mathematical function corresponding to the paths to be welded and a mathematical function corresponding to a sine first or cosine line may be obtained, and the mathematical function corresponding to the paths to be welded is superimposed by using the mathematical function corresponding to the sine lines or cosine lines, so as to obtain the mathematical function corresponding to the paths after the superimposition processing, and generate the paths after the superimposition processing according to the mathematical function corresponding to the paths after the superimposition processing, for example, the mathematical function corresponding to the paths to be welded (as shown in fig. 4) is a polar coordinate equation:
r＝a+bθ
wherein r is2＝x2+y2
The mathematical function for the sinogram (as shown in figure 5) is:
y＝ksinx
substituting the mathematical function value y corresponding to the sine line into x of the polar equation to obtain a mathematical function corresponding to the superimposed path, wherein the corresponding superimposed path is shown in fig. 7.
Alternatively, the sine line or the cosine line may be a standard sine curve or a standard cosine curve, or may be a sine curve or a cosine curve as shown in fig. 5 or fig. 6, which is not limited herein. The paths to be welded shown in fig. 4 are superimposed by using the sine curve or the cosine curve shown in fig. 5, the obtained paths after the superimposition processing are shown in fig. 7, the paths to be welded shown in fig. 4 are superimposed by using the sine curve or the cosine curve shown in fig. 6, and the obtained paths after the superimposition processing are shown in fig. 8.
Alternatively, the specific shape path of the sine line and the cosine line may be set by an operator according to actual requirements, for example, a user may input parameters of the sine line or the cosine line (for example, k in the above formula), correspondingly generate the sine line or the cosine line according to the parameters of the sine line or the cosine line input by the user, and determine a mathematical function corresponding to the sine line or the cosine line.
In step S30, the two plate materials are welded along the superimposed path.
In this embodiment, after the path after the stacking process is generated, the two plates are welded according to the path after the stacking process, and since the path after the stacking process is still in the original welding area and the length of the welding path is longer, the area of the welding connection in the original welding area can be increased.
In the technical scheme disclosed in the embodiment, the sine line or the cosine line is superposed on the path to be welded, so that the welding path is still limited in the original welding area, but the length of the welding path is longer, and thus, more welding points are formed between the plates in the original welding area, the welding bonding force between the plates is increased on the premise of ensuring that the welding area is not increased, and the welding is firmer.
In another embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, the step S30 includes:
step S31, stacking two plates, wherein the two plates comprise a first plate and a second plate, and the lower surface of the first plate is attached to the upper surface of the second plate;
in this embodiment, the plate includes an upper surface, a lower surface, and a side surface. As shown in fig. 9, when welding two plate materials, the two plate materials are stacked, that is, the first plate material 1 is stacked on the second plate material 2, and at this time, the lower surface of the first plate material 1 is attached to the upper surface of the second plate material 2.
Step S32, emitting welding laser to the upper surface of the first plate material, and controlling the welding laser to move according to the path after the superposition processing, so that the welding laser penetrates through the first plate material, and a welding connection portion corresponding to the path after the superposition processing is formed between the lower surface of the first plate material and the upper surface of the second plate material.
In the present embodiment, by controlling the laser welding device to emit the welding laser to the upper surface of the first plate 1, under the action of the welding laser, the corresponding region of the first plate 1 is melted through, and the corresponding region of the upper surface of the second plate 2 is also melted, the melted plates form the welding connection portion 3 between the lower surface of the first plate 1 and the upper surface of the second plate 2, and the welding connection portion 3 is used for welding and connecting the first plate 1 and the second plate 2, so as to realize the welding between the first plate 1 and the second plate 2. The welding laser is controlled to move along a path after the overlaying process (e.g., a path shown in fig. 7 or 8), so that the welded connection 3 formed between the lower surface of the first sheet material 1 and the upper surface of the second sheet material 2 also corresponds to the path after the overlaying process, for example, as shown in fig. 9, fig. 9 is a cross-sectional view, and the welded connection 3 in fig. 9 corresponds to the path to be welded shown in fig. 4.
In the technical scheme disclosed in this embodiment, two plates are stacked, welding laser is emitted to the upper surface of the first plate, and the welding laser is controlled to move according to the path after the stacking process, so that the welding between the first plate and the second plate is realized.
