[0035] See also Figure 1 As shown, another embodiment of the present invention provides a processing table for an automatic ball melting machine, comprising a supporting module 9 and the clamp.

[0036] Among them, see Figure 6 As shown, in this embodiment, the support module 9 includes a support frame 901, and a positioning pin 902 is provided on the support frame 901. The positioning pin 902 corresponds to the positioning hole 101 one by one.

Through the cooperation between the positioning pin 902 and the oil-free sleeve 6 in the corresponding positioning hole 101, the fast and accurate loading and fast and convenient unloading of the fixture are achieved.

[0037] For further information, see Figure 6 As shown, in this embodiment, a diffuse reflection photoelectric sensor 903 and a reflected photoelectric sensor 904 are provided on the support frame 901, and the diffuse reflection photoelectric sensor 903 and the reflected photoelectric sensor 904 are used to detect whether there is a clamp on the support module 9 and whether the clamp is installed in place on the support module 9.

[0038] The working principle of the utility model is as follows:

[0039] Before use, see Figure 7 As shown in the figure (label a in the figure represents a welding system; label b in the figure represents a fixture; label d in the figure represents a special tooling), the support module 9 of the processing table is connected to the wire welding system. At this time, the diffuse reflection photoelectric sensor 903 and the reflected photoelectric sensor 904 are connected to the electrical signal of the welding system; and the negative pole of the power supply in the welding system is connected to the support frame 901, wherein the negative pole current of the power supply can be introduced into the fixture through the support frame 901.

[0040] When in use, first fix the clamp with a special tooling to ensure that it will not move; the operator then pulls up the handle 2 to drive the movable copper pole 4 to move, so that a certain small gap is separated between the fixed copper pole 3 and the movable copper pole 4, and then turns the front end of the plug 7 to between the handle 2 and the frame 1 to maintain the gap between the fixed copper pole 3 and the movable copper pole 4. At this time, the spring 5 is further compressed, and the clamping groove 304 formed between the contact surface of the fixed copper pole 3 and the movable copper pole 4 is enlarged; then after the guide wire passes through the clamping groove 304, pull up the handle 2 to rotate the plug 7 away from between the handle 2 and the frame 1, and then release the handle 2. At this time, the movable copper pole 4 is driven by the reaction of the spring 5 to move toward the fixed copper pole 3, and finally fits tightly with the fixed copper pole 3 to achieve loading and fixation of the guide wire.

[0041] After completing the guide wire loading, remove the fixture from the rotating tooling and install it into the support module 9. At this time, the positioning pins 902 are respectively inserted into the oil-free sleeves 6 in the corresponding positioning holes 101, and the diffuse reflection photoelectric sensor 903 and the reflected photoelectric sensor 904 respectively transmit the detection signals back to the welding system in real time to ensure that the fixture is installed in place.

[0042] After completing the guide wire welding process, remove the fixture from the support module 9 and load it onto a special tooling. After separating the fixed copper pole 3 and the movable copper pole 4 by a certain small gap as described above, remove the guide wire, and one round of processing is completed; re-install the new guide wire, the steps are as described above, and will not be repeated here, and enter the next round of processing.

[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
