[0033] like Figures 1-6 As shown, a probe welding automatic mold changing mechanism includes an equipment base 1 and a welding laser component 6.

[0037] The welding laser assembly 6 includes a welding Z-axis connecting plate 14 connected to the welding Z-axis module 9, a welding Y-axis electric slide 15 is installed on the welding Z-axis connecting plate 14, a welding X-axis electric slide 16 is installed on the welding Y-axis electric slide 15, a laser head mounting frame 17 is installed on the welding X-axis electric slide 16, a manual rotating table 18 is installed on the laser head mounting frame 17, and a welding head 19 is installed on the manual rotating table 18.

[0038] A clamping assembly X-axis module 13 is installed on the welding clamping gantry on the device base 1 on the side of the probe plate 5 to be welded along the negative direction of the Y-axis, a clamping assembly Z-axis module 12 is installed on the clamping assembly X-axis module 13, a clamping assembly Y-axis module 11 is installed on the clamping assembly Z-axis module 12, and a welding clamping assembly 10 is installed on the clamping assembly Y-axis module 11.

[0039] The welding clamping assembly 10 comprises a clamping Y-axis connecting plate 20 connected with the clamping assembly Y-axis module 11, a clamping jaw mounting plate 21 is installed on the clamping Y-axis connecting plate 20, a fixed clamping jaw 26 is installed on the clamping jaw mounting plate 21 along the side of the positive direction of the X-axis through a fixed clamping jaw seat 25, and a movable clamping jaw 24 is installed on the clamping jaw mounting plate 21 along the side of the negative direction of the X-axis through a movable clamping jaw seat 23.

[0040] A differential head 27 is installed on the clamping jaw mounting plate 21 on the side of the top of the movable clamping jaw seat 23 through a differential head seat 28, and the differential head 27 is distributed along the direction of the X-axis.

[0041] At least one clamping jaw limiting block 29 is installed on the clamping jaw mounting plate 21 on the side of the negative direction of the X-axis of the movable clamping jaw seat 23.

[0042] The relationship between the various components of the utility model is as follows:

[0043] The welding Y-axis module 2 is fixed on the device base 1 through screws, the welding X-axis module 3 is installed on the welding Y-axis module 2 through screws, the welding rotating platform 4 is installed on the welding X-axis module 3 through screws, and the device base 1 has high perpendicularity, parallelism and other precise positional relationships with the welding Y-axis module 2, the welding X-axis module 3 and the welding rotating platform 4. In the welding process, the probe plate 5 to be welded is firmly adsorbed on the welding rotating platform 4 through vacuum.

[0044] The positioning camera Z-axis module 8 is installed on the positioning camera gantry of the device base 1 through screws and has a high perpendicularity assembly relationship with the welding rotating platform 4, and the positioning camera 7 is installed on the positioning camera Z-axis module 8 through screws.

[0045] The welding Z-axis module 9 is installed on the column of the device base 1 through screws and has a high perpendicularity assembly relationship with the welding rotating platform 4, and the welding laser assembly 6 is installed on the welding Z-axis module 9 through screws.

[0046] The clamping assembly X-axis module 13 is installed on the gantry column of the equipment base 1 by screws and has a high verticality assembly relationship with the welding rotary platform 4, the clamping assembly Z-axis module 12 is installed on the clamping assembly X-axis module 13 by screws, the clamping assembly Y-axis module 11 is installed on the clamping assembly Z-axis module 12 by screws, and the welding clamping assembly 10 is installed on the clamping assembly Y-axis module 11 by screws.

[0047] When the probe welding automatic changing mechanism performs short probe welding work, the welding clamping assembly 10 clamps the probe, and under the linkage of the clamping assembly Y-axis module 11, the clamping assembly Z-axis module 12 and the clamping assembly X-axis module 13, the probe is conveyed to the lower side of the positioning camera 7. The positioning camera 7 is driven by the positioning camera Z-axis module 8 to automatically focus on the needle tip of the probe, so as to obtain the XYZ three-dimensional coordinates of the needle tip. Then, according to the needle tip coordinate information, the clamping assembly Z-axis module 12, the welding Y-axis module 2 and the welding X-axis module 3 are linked to make the probe clamped by the welding clamping assembly 10 reach the welding position, and laser welding is performed by the welding laser assembly 6. After welding, each axis returns to the initial position to perform the next short probe welding work cycle.

[0048] As Figures 4-6 When it is a narrow pitch welding probe, different length probes are used to keep the detection needle tip consistent, and the length different probe interval welding is used to ensure the narrow pitch probe welding while leaving a size allowance for the welding clamping mechanism of the probe.

[0049] The welding work sequence when it is a narrow pitch welding probe is as follows: the first stage: first, clamp the short probe for welding, at this time, the short probe pitch is twice the finished product pitch, which is convenient for the clamping mechanism to work, and when the short probe is completely welded, the second stage is started: under the condition of keeping the needle tip in the same position, the clamping mechanism clamping the long probe performs welding work behind the short probe, and the pitch is also twice the finished product pitch. In the third stage, it means that the long and short probes are completed.

[0050] When the short probe 31 is welded and preparations begin for welding the long probe 32, the automatic probe welding change mechanism operates as follows: Based on the size difference between the long and short probes, under program control, the clamping assembly Y-axis module 11 drives the welding clamping assembly 10 to automatically move to the clamping position of the long probe. The welding clamping assembly 10 then clamps the long probe and, under the linkage of the clamping assembly Y-axis module 11, the clamping assembly Z-axis module 12, and the clamping assembly X-axis module 13, is transported to the bottom of the positioning camera 7. The positioning camera 7, driven by the positioning camera Z-axis module 8, automatically focuses on the long probe tip to obtain the X, Y, and Z coordinates of the tip. Then, based on the tip coordinate information, the clamping assembly Z-axis module 12, the welding Y-axis module 2, and the welding X-axis module 3 are linked to move the long probe clamped by the welding clamping assembly 10 to the welding position, where laser welding is performed by the welding laser assembly 6. After welding is completed, each axis returns to its initial position and the next long probe welding cycle begins.

[0051] The device has the function of automatically correcting the position parameters. When the long and short probes are switched, the device will automatically calculate the theoretical tip position of the new probe after the switch based on the tip position of the probe that was successfully welded last time. Accordingly, the clamping component Y-axis module 11 drives the welding clamping component 10 to automatically move to the set position according to the process parameters, and then clamps the new probe. The clamping component Z-axis module 12 and the clamping component X-axis module 13 are sent to the bottom of the positioning camera 7. After the positioning camera 7 locates the actual position of the needle tip, the actual coordinates of the needle tip are compared with the theoretical coordinates to obtain the correction data, and the difference in XYZ coordinates is automatically sent to the control program of the clamping component Z-axis module 12, the welding Y-axis module 2 and the welding X-axis module 3 respectively as the compensation value for the next welding work. At this point, the automatic correction setting of the position parameters after the long and short probes are switched is completed. Among them, the above-mentioned control program is a conventional technical means in this field and will not be described in detail here.

[0052] This new system incorporates a high-precision motion axis into the welding clamping assembly, automatically switching the clamping mechanism's working position based on probe specifications. Combined with a visual positioning system, the welding system's motion axes automatically adjust parameters. This allows for automated probe model switching during welding production, eliminating the need for manual intervention. This significantly reduces production commissioning time, eliminates the influence of human factors, and effectively ensures the stability of welding precision.
