The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The welding arc automatic generation method provided by the embodiment of the invention can be applied to the application environment shown in fig. 1. Specifically, the automatic welding arc generation method is applied to an automatic welding arc generation system, which comprises a client and a server shown in fig. 1, wherein the client and the server are in communication through a network, and the client and the server are used for solving the problem of low accuracy in generating welding arcs in the prior art. The client is also called a user side, and refers to a program corresponding to the server and providing local services for the client. The client may be installed on, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. The server may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers.

In an embodiment, as shown in fig. 2, there is provided an automatic generation method of welding wire arcs, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:

s10: receiving an automatic generation instruction of a welding arc; and the welding arc automatic generation instruction comprises the arc formulation requirement information corresponding to the piece to be welded.

It can be understood that the welding arc automatic generation instruction may be automatically generated after receiving the preset arc parameter set corresponding to the to-be-welded part sent by the user and the arc formulation requirement information, or may be directly sent by the user through a mobile terminal such as a mobile phone, a computer, or other servers. The to-be-welded parts are semiconductor materials to be welded, and different to-be-welded parts can formulate demand information corresponding to different wire arcs. The wire arc formulation requirement information can include but is not limited to material information such as a to-be-welded part (the material information can include materials such as the to-be-welded part, thickness or structural information and the like), tail welding information (for example, some to-be-welded materials have requirements for obviously attaching the tail part of the welding wire arc to the ground, so that one piece of tail welding information can be set, the requirement for obviously attaching the ground can be met when the welding wire arc is generated, and the bad phenomenon that two welding parts fall off due to the fact that colloid expands when heated) can be prevented.

S20: and acquiring a starting welding coordinate of a starting welding point and an end point welding coordinate of an end point welding point corresponding to the to-be-welded piece.

It is understood that the to-be-welded component in this embodiment is a semiconductor material, so the initial welding point can be regarded as a wafer dot of the to-be-welded component, and the final welding point can be regarded as an electrode pin point, and the welding wire arc generated in this embodiment is a supporting wire between the wafer dot and the electrode pin point. Generally, the abscissa and the ordinate of the initial welding coordinate of the initial welding point are set to 0, and the end welding coordinate of the end welding point can be calculated and generated according to the distance mapping between the wafer and the electrode pin.

S30: and determining a line arc bending node corresponding to the to-be-welded part according to the line arc formulation requirement information.

It is to be understood that in the above description it is pointed out that the arc making requirement information comprises material information. The different material information may be different in the number of the line arc bending nodes connected to the finally generated welding line arc, and since the line arc spans or the line arc widths of the welding line arcs required to be made of the parts to be welded made of different materials are different, the number of the line arc bending nodes required to be set for the different parts to be welded is different, and then the number of the intermediate connection nodes in the line arc bending nodes corresponding to the parts to be welded can be determined according to the material information. Further, tail welding information is also included in the wire arc formulation requirement information, the tail welding information is used for representing whether the material to be welded has the requirement that the tail of the welding wire arc needs to be obviously attached to the ground, and if the tail welding information represents that the material to be welded has the requirement that the tail of the welding wire arc needs to be obviously attached to the ground, a tail connection node is also included in the wire arc bending node; and if the tail welding information indicates that the material to be welded does not have the requirement that the tail of the welding arc needs to be obviously attached to the ground, the tail connecting node is not included in the wire arc bending node.

Furthermore, because the initial welding point, the end welding point and the wire arc bending node all have three-dimensional coordinates, the middle connecting node and the tail connecting node in the wire arc bending node are both arranged between the initial welding point and the end welding point, and the tail connecting node is arranged between the last middle connecting node and the end welding point, namely the tail connecting node is arranged at one end close to the end welding point; each intermediate node sets gradually between originated welding point and terminal point welding point, if there is the afterbody connected node, then each intermediate node sets gradually between originated welding point and afterbody connected node.

S40: acquiring a preset arc parameter set, and generating a welding arc corresponding to the to-be-welded part according to the preset arc parameter set, the arc formulation requirement information, the initial welding coordinate and the end point welding coordinate; the welding wire loop connects the initial welding point, each wire loop bending node and the final welding point.

The preset arc parameter set may include, but is not limited to, a line length parameter (the line length parameter represents a linear distance from a start welding point to an end welding point), a line arc height parameter (the line arc height parameter refers to a height difference between a set first intermediate connection node and the start welding point), a node connection parameter (the node connection parameter is a set angle value required to be bent at each arc bending node), or a welding point drop value.

Specifically, after determining the arc bending node corresponding to the to-be-welded part according to the arc setting demand information, acquiring a preset arc parameter set, determining the demand information, a starting welding coordinate and an end point welding coordinate according to the preset arc parameter set, the arc, and determining the coordinate information corresponding to each arc bending node, so as to generate a welding arc according to the starting welding coordinate, the coordinate information corresponding to each arc bending node and the end point welding coordinate, that is, the starting welding point, the arc bending node and the end point welding point are connected through the welding arc.

Further, a start welding point and an end welding point may be regarded as a group of welding point groups to be welded, and if there are multiple groups of welding point groups to be welded, the welding arc corresponding to each welding point group to be welded may be determined through the above steps, so as to determine all welding arcs in the welding part to be welded. Further, the parameters in the preset arc parameter group except for the line length parameter set in the embodiment can be fixed, and the welding arcs are determined only by setting the demand information and the preset arc parameter group according to the determined number of the arc bending nodes and the determined arcs, so that the arc top height of each welding arc in the part to be welded is consistent, the arc shape of the welding line is consistent, and the accuracy of generating the welding arcs is improved.

In this embodiment, establish demand information through the arc that corresponds with treating the welding piece and determine the arc bending node, the arc of welding is established to the quantity of the arc bending node and the arc that rethread fixed preset arc parameter group, the arc of determining and demand information and determines the welding arc, so can guarantee to treat that the arc top height of each welding arc is unanimous in the welding piece, and then makes the welding arc shape reach unanimity, has improved the accuracy that the welding arc generated.

In an embodiment, in step S30, that is, the determining the curve bending node corresponding to the to-be-welded part according to the curve formulation requirement information includes:

and analyzing the wire arc formulation requirement information to determine material information and tail welding information corresponding to the to-be-welded parts.

It can be understood that the analysis of the wire arc formulation requirement information mainly includes text analysis of the wire arc formulation requirement information, so that material information (for example, a manner of identifying a material entity) and tail welding information (the tail welding information is substantially a numerical value, and further, analysis and identification can be performed in a numerical detection manner, for example) in the wire arc formulation requirement information are identified.

And determining an intermediate connecting node according to the material information, and determining whether a tail connecting node exists according to the tail welding information.

Specifically, requirement information is formulated to the wire arc, after material information and tail welding information corresponding to the to-be-welded parts are determined, the analyzed material information can be obtained, and because wire arc spans or wire arc widths of welding wire arcs, which need to be made, of the to-be-welded parts of different materials are different, the number of middle connection nodes, which need to be set, of the to-be-welded parts is different, and then the number of the middle connection nodes in the wire arc bending nodes corresponding to the to-be-welded parts can be determined according to the material information, namely, the number of the middle connection nodes can be one or two.

Further, performing numerical value identification on the tail welding information, and determining whether a tail connection node exists according to a numerical value obtained through identification, for example, when the numerical value information (defined as the length of the tail of the welding arc of the to-be-welded member required to be obviously attached to the ground) included in the tail welding information is detected to be not zero, the existence of the tail connection node is represented; when the numerical information (the numerical information defines the length of the tail part of the welding arc to be welded which needs to be obviously attached) contained in the tail part welding information is detected to be zero, the tail part connecting node is represented to be absent.

And when the existence of the tail connecting node is determined according to the tail welding information, recording all the middle connecting nodes and the tail connecting node as the line arc bending node.

And recording all the intermediate connection nodes as the wire arc bending nodes when determining that no tail connection nodes exist according to the tail welding information.

Specifically, in the above description, when it is detected that the numerical information included in the tail information is not zero, it may be determined that the tail connection node exists, and then all the intermediate connection nodes and the tail connection node may be recorded together as the line arc bending node; when the numerical information contained in the tail information is detected to be zero, it is determined that no tail connection node exists, and all the intermediate connection nodes can be recorded as the line arc bending nodes.

In this embodiment, establish demand information according to the line arc and determine corresponding material information and afterbody welding information, confirm the quantity of concrete intermediate junction node to and whether there is afterbody welding node, provide accurate line arc bending node for the follow-up welding arc that generates, and then improved the accuracy that welding line arc generated.

Therefore, after detecting the number of intermediate connection nodes and the number of tail connection nodes contained in the wire arc bending nodes, if the wire arc bending nodes only contain one intermediate connection node and do not contain a tail connection node, the requirement that the tail of the to-be-welded part is attached to the ground does not exist, and then the wire length parameter, the wire arc height parameter, the node connection parameter and the welding point drop value in the preset wire arc parameter group are directly obtained.

Illustratively, the former node coordinates are the coordinates of the intermediate connection node 3 of the first arc shown in fig. 3.

Illustratively, as shown in fig. 4, fig. 4 is an example of a second wire arc having two intermediate connection nodes, one intermediate connection node 3 and another intermediate connection node 4, between wafer 1 having a start pad a1 and electrode pin 2 having a finish pad a 2.
