The phrase "and / or" used herein includes all or any one of the associated listed items and all combinations thereof.

[0038] The embodiment provides a welding method for a welding grinding process. In specific implementation, the welding method comprises the following steps: first, acquiring the position of a welding spot and the length of a welding wire; second, generating a grinding track of a sliding table of a welding machine according to the position of the welding spot and the length of the welding wire, wherein the grinding track is a circular motion track; third, determining the translation distance of the sliding table of the welding machine in the horizontal direction and the vertical direction based on the circular motion track, and superimposing a track algorithm in the horizontal direction of the sliding table of the welding machine to convert the grinding track of the sliding table of the welding machine from the circular motion track to a spiral motion track; and fourth, controlling the sliding table of the welding machine to perform a welding operation based on the spiral motion track. The embodiment introduces a new grinding track algorithm in the grinding process, increases the Table movement of the sliding table of the welding machine in the horizontal direction, converts the circular motion track into the spiral motion track, and thus increases the surface area of the two welding fish tails in contact with the material, thereby improving the fish tail residue and fish tail tension. Therefore, the welding method for the welding grinding process can effectively improve the welding efficiency during the welding grinding process.

[0039] For example, when the grinding track of the sliding table (XY-Table) of the welding machine is a circular track during the welding grinding process, the grinding track is a circular track with the position of the welding spot as the center and the length of the welding wire as the radius. Since it does not have horizontal displacement, the surface area of the two welding fish tails in contact with the material is limited to the repeatedly drawn circular track. In the embodiment, the grinding track of the grinding process is converted from the circular motion track to the spiral motion track by superimposing a track algorithm in the horizontal direction of the grinding process, which brings the movement displacement of the XY-Table in the horizontal direction X-axis, avoids the repeatedly drawn grinding track, and increases the surface area of the two welding fish tails in contact with the material during the welding grinding process, thereby improving the fish tail residue and fish tail tension.

[0040] Exemplary method

[0041] The welding method for the welding grinding process of the embodiment can be applied in a wire bonding machine. As shown in FIG. 1, the welding method for the welding grinding process of the embodiment comprises the following steps: Figure 1

[0042] Step S100, obtaining the position of the welding point and the length of the wire, and generating a grinding track of a slide table of a wire bonding machine according to the position of the welding point and the length of the wire, wherein the grinding track is a circular motion track.

[0043] Specifically, on the existing grinding process, the grinding track shape of the slide table of the wire bonding machine has a linear direction, a perpendicular linear direction, a circular track and an elliptical track. The welding method for the welding grinding process of the embodiment is based on the grinding track of the slide table of the wire bonding machine being a circular track, so the embodiment first needs to obtain the grinding track of the slide table of the wire bonding machine according to the position of the welding point and the length of the wire, and then further superimposes a grinding algorithm on the grinding track to increase the surface area of the contact between the two-wire fish tail and the material, thereby improving the welding efficiency during the welding grinding process.

[0044] Preferably, the welding method for the welding grinding process provided by the embodiment can also be based on other existing grinding track shapes to propose different improvement schemes and superimpose different track algorithms to achieve the effect of increasing the surface area of the contact between the two-wire fish tail and the material, which is not limited in the embodiment.

[0045] In one implementation, before the embodiment obtains the position of the welding point and the length of the wire and generates a grinding track of a slide table of a wire bonding machine according to the position of the welding point and the length of the wire, the following steps are included:

[0046] Step S001, detecting the position information of the material to be welded, and determining whether the material to be welded is within a preset position range according to the position information;

[0047] Step S002, when the material to be welded is within the preset position range, obtaining the position of the welding point and the length of the wire.

[0048] In the specific implementation process, after generating the grinding track of the slide table of the wire bonding machine, the embodiment will start to set different track algorithms according to different directions of the two-wire and different lengths of the wire. Therefore, in order to improve the implementation efficiency in the embodiment, it is necessary to detect whether the material to be welded is placed within the welding position range of the wire bonding machine before generating the grinding track of the slide table of the wire bonding machine.

[0049] ​Specifically, a welding grinding range of a material to be welded is preset in the embodiment, which can be set by a user or detected by a detection device. The detection method can be infrared detection or the like, which is not limited in the embodiment. When the user turns on the start switch of the wire bonding machine, the embodiment first detects the position information of the material to be welded, and determines whether the material to be welded is in the preset position range according to the position information. When the material to be welded is in the preset position range, the position of the welding point and the length of the wire are obtained.

[0050] After step S002, the embodiment starts step S100, which specifically includes:

[0051] In step S101, the position of the welding point and the length of the wire are obtained, and the slide table of the wire bonding machine is controlled to move in a circular trajectory with the position of the welding point as the center and the length of the wire as the radius. The circular trajectory is realized by the difference of sin function time sequence, and the circular motion trajectory function is:

[0052] Wherein, a is the independent variable angle in the polar coordinate system of the circle.

[0053] Since the welding method for the welding grinding process in the embodiment is based on the grinding trajectory of the slide table of the wire bonding machine being a circular trajectory, the embodiment first needs to determine the circular motion trajectory of the grinding process. In the grinding process, the slide table (XY-Table) of the wire bonding machine determines the motion trajectory of the grinding according to the position of the welding point and the length of the wire. The XY-Table moves in a circular trajectory with the position of the welding point as the center and the length of the wire as the radius. In the mathematical equation, the parametric equation of the trajectory of the circle is: X=sin(a), Y=cos(a). When the period of the sin function is different by π / 2, there is sin(a-π / 2)=cos(a), so the circular motion trajectory in the embodiment can be realized by the difference of sin function time sequence, that is, by the function X=sin(a) and the function Y=sin(a-π / 2).

[0054] Further, when the grinding process is a circular motion trajectory, the specific process of controlling the X-axis and Y-axis of the XY-Table to realize the adhesion between the wire and the material is as follows: the position of the welding point is taken as the center, the XY-Table is controlled to move from the center to the arc along the predetermined trajectory, and the X-axis and Y-axis of the XY-Table are repeatedly moved along the circular trajectory N times, and finally the XY-Table is moved from the arc back to the center position to realize the adhesion between the wire and the material.

[0055] In an implementation manner, step S001 of the embodiment further includes the following steps:

[0056] Step S003, when the material to be welded is out of the preset position range, the output device sends a reminder.

[0057] In the implementation process, in order to improve the implementation efficiency in the embodiment, when the user turns on the start switch of the wire bonding machine, the embodiment will preferentially detect the position information of the material to be welded, and judge whether the material to be welded is within the preset position range according to the position information. When the material to be welded is out of the preset position range, the output device sends a reminder.

[0058] Preferably, the output device sends a reminder in many ways, which can be outputting text to remind the user on the terminal device, or sending different colored lights to remind, or playing a bell sound to remind, which is not limited in the embodiment. Through the reminder sent by the output device, the user can be informed to further check the position of the material to be welded by manual detection. When the placement position of the material to be welded is out of the preset position range, the user needs to adjust the position, or when the user forgets to place the material to be welded, the user is reminded to supplement the material and place it in the preset position range.

[0059] Step S200, based on the circular motion trajectory, determine the translation distance of the slide table of the wire bonding machine in the horizontal direction and the vertical direction, and superimpose trajectory algorithm in the horizontal direction of the slide table of the wire bonding machine, convert the grinding trajectory of the slide table of the wire bonding machine from the circular motion trajectory to the spiral motion trajectory.

[0060] In the implementation process, in order to increase the contact area between the two-wire fish tail and the material during the welding and grinding process, the embodiment adopts the method of replacing the circular trajectory with the spiral trajectory.

[0061] In one implementation, when the embodiment superimposes trajectory algorithm in the horizontal direction of the slide table of the wire bonding machine to convert the grinding trajectory of the slide table of the wire bonding machine from the circular motion trajectory to the spiral motion trajectory, it includes the following steps:

[0062] Step S201, superimpose an X=Ka function in the horizontal direction of the circular motion trajectory, realize the conversion of the grinding trajectory of the slide table of the wire bonding machine to the spiral motion trajectory, and the spiral motion trajectory function is:

[0063] Wherein, a is the independent variable angle in the polar coordinate system of the circle, and K is a constant.

[0064] Specifically, the embodiment realizes the trajectory of the equidistant spiral line by increasing the horizontal displacement in the line direction based on the circular trajectory, so as to increase the contact area between the two-wire fish tail and the material and achieve the expected welding effect. In the embodiment, the function is used to show the change mode between the circular trajectory and the spiral trajectory. Specifically, as shown inFigure 2 As shown in the above, a constant function X=K*a is superimposed on the X-axis direction of the circular motion trajectory in a form of function addition, that is, the displacement of the grinding process in the horizontal direction is X=Sin(a)+K*a. Then, the spiral motion trajectory is realized by the function X=Sin(a)+K*a and the function Y=Sin(a-pi / 2).

[0065] Preferably, as shown in the above, the spiral motion trajectory in the embodiment is a spiral gradual pushing motion trajectory in the horizontal direction. Figure 3

[0066] Specifically, in the embodiment, the horizontal displacement of the circular motion trajectory is less than that of the spiral motion trajectory. When the XY-table moves along the circular trajectory with the position of the welding spot as the center and the length of the welding line as the radius, the XY motion of the table is repeated N times along the circular trajectory, and finally returns to the center position from the circular arc. Therefore, the circular trajectory is cyclically superimposed at the same position, and the circular motion trajectory does not have displacement in the horizontal direction. Therefore, when the special material with a relatively thin aluminum layer is processed, the circular motion trajectory often limits the frequency and times of the grinding process. However, the improved spiral motion trajectory in the embodiment is obtained by superimposing the trajectory algorithm in the horizontal direction of the circular motion trajectory. Therefore, when the grinding trajectory is the spiral motion, the spiral motion trajectory has displacement in the horizontal direction, that is, the horizontal displacement of the circular motion trajectory is less than that of the spiral motion trajectory. At the same time, the displacement in the horizontal direction can increase the surface area of the two welding fish tails in contact with the material, so as to improve the fish tail residue and fish tail tension, and effectively solve the problems of limited frequency and times of the grinding process for the special material with a relatively thin aluminum layer.

[0067] In step S300, the slide table of the welding line machine is controlled to perform the welding operation based on the spiral motion trajectory.

[0068] In the embodiment, when the grinding trajectory is the spiral motion trajectory, the grinding trajectory of the XY-table has displacement in the horizontal direction X-axis, which can overcome the phenomenon that the original grinding trajectory is the circular motion trajectory and the trajectory is repeatedly drawn. Therefore, when the grinding process is welded based on the spiral motion trajectory of the embodiment, the fish tail residue and fish tail tension can be improved.

[0069] ​In summary, the embodiment provides a welding method for a welding grinding process. First, the position of a welding spot and the length of a welding wire are obtained. A grinding track of a sliding table of a welding machine is generated according to the position of the welding spot and the length of the welding wire, wherein the grinding track is a circular motion track. Then, the translation distance of the sliding table of the welding machine in the horizontal direction and the vertical direction is determined based on the circular motion track, and a trajectory algorithm is superimposed in the horizontal direction of the sliding table of the welding machine, so as to convert the grinding track of the sliding table of the welding machine from the circular motion track to a spiral motion track. Finally, the sliding table of the welding machine is controlled to perform a welding operation based on the spiral motion track. In the embodiment, a new grinding track algorithm is introduced in the grinding process, the Table movement of the sliding table of the welding machine in the horizontal direction is increased, the circular motion track is converted into the spiral motion track, the surface area of the two welding fish tails in contact with the material is increased, and the effects of improving the fish tail residue and the fish tail tension are achieved. Therefore, the welding method for the welding grinding process can effectively improve the welding efficiency in the welding grinding process.
