The fifth stepping motor 60 is installed on the other moving seat 5.

[0043] The working principle of a welding and splicing device for platinum mesh processing is as follows:

[0044] First, connect the wires of all electrical equipment and power them on. Then, pass the platinum-rhodium wires 38 through the first straightening device 17 and the second straightening device 40 respectively, and then clamp the platinum-rhodium wires 38 with the first clamp 37 and the second clamp. Then, start the second servo motor 24 and the third servo motor 34. Control the rotation of the second belt 23 through the second servo motor 24, control the rotation of the second transmission wheel 22 through the second belt 23, thereby controlling the rotation of the driving roller 20. Clamp the platinum-rhodium wire 38 in the Y-axis direction through the driving roller 20, thereby controlling the platinum-rhodium wire 38 in the Y-axis direction to move backward. Then, start the third servo motor 34, thereby controlling the rotation of the third belt 33, and further controlling the rotation of the third transmission wheel 32, thereby controlling the rotation of the second screw rod 30. The L-shaped moving block 35 is threadedly connected to the second screw rod 30, and the L-shaped moving block 35 is sleeved on the first guide rod 31. When the second screw rod 30 rotates, the movement of the L-shaped moving block 35 is controlled, and further the movement of the third electric push rod 36 and the first clamp 37 is controlled.

[0045] When the first clamp 37 holds the platinum-rhodium wire 38 and moves it to the rear end, the second electric push rod 26 is started. The first cutting disc 27 and the second stepping motor 28 at the lower end are controlled to descend through the second electric push rod 26. While descending, the second stepping motor 28 is started, so as to control the rotation of the first cutting disc 27, and then cut off the platinum-rhodium wire 38. Then the third electric push rod 36 is started to control the descent of the first clamp 37, so as to place the platinum-rhodium wire 38 in the Y-axis direction on the positioning tool 13. Then the first servo motor 10 is started. The rotation of the first belt 9 is controlled through the first servo motor 10, so as to control the rotation of the first transmission wheel 8, and then control the rotation of the rotating shaft 7 on one side, so as to control the rotation of the rotating wheel 11, and then control the rotation of the conveyor belt 12, so as to control the horizontal movement of the positioning tool 13, and then control the horizontal movement of the platinum-rhodium wire 38 falling on the positioning tool 13; then repeat the above steps to cover the platinum-rhodium wire 38 in the Y-axis direction.

[0046] When the platinum-rhodium wire 38 in the Y-axis direction is covered, the first electric push rod 14 is started. The supporting plate 15 is pushed upward through the first electric push rod 14, so as to lift all the platinum-rhodium wires 38 in the Y-axis direction. At this time, the platinum-rhodium wires 38 in the Y-axis direction fall into the positioning grooves transversely opened on the top surface of the supporting plate 15; then the fourth servo motor 46 is started. The rotation of the third screw rod 48 is controlled through the fourth servo motor 46. Since the baffle plate 49 is threadedly connected with the third screw rod 48, when the third screw rod 48 rotates, the movement of the baffle plate 49 is controlled, so as to control the movement of the fifth electric push rod 50 and the second clamp, so as to pull out the platinum-rhodium wire 38 in the X-axis direction. Then the fourth electric push rod 43 is started. The second cutting disc 44 and the third stepping motor 45 at the lower end are controlled to descend through the fourth electric push rod 43. While descending, the third stepping motor 45 is started, so as to control the rotation of the second cutting disc 44, and then cut the pulled-out platinum-rhodium wire 38.

[0047] When the cutting is completed, the platinum-rhodium wire 38 in the X-axis direction will fall into the guiding tool 39. Then the first stepping motor 4 is started. The rotation of the first screw rod 3 is controlled through the first stepping motor 4. Since the moving seat 5 is threadedly connected with the first screw rod 3, when the first screw rod 3 rotates, the movement of the moving seat 5 is controlled, and then the movement of the guiding tool 39 is controlled. When the lower end of the guiding tool 39 moves to the position where welding is required, the fifth stepping motor 60 is started. The rotation of the fourth belt 59 is controlled through the fifth stepping motor 60, so as to control the rotation of the fourth transmission wheel 58, and then control the rotation of the rotating plate 57, so as to discharge the cut platinum-rhodium wire 38. At this time, the platinum-rhodium wire 38 in the X-axis direction falls on the platinum-rhodium wire 38 in the Y-axis direction.

[0048] Start the fourth stepping motor 53, control the rotation of the bidirectional lead screw 51 through the fourth stepping motor 53. Since the moving connecting seat 54 is threadedly connected to the bidirectional lead screw 51 and is sleeved on the second guide rod 52, when the bidirectional lead screw 51 rotates, the movement of the two ends of the moving connecting seat 54 is controlled, and further the movement of the air cylinder 55 and the welding torch 56 is controlled. Then start the air cylinder 55 to control the welding torch 56 to descend, so as to weld the platinum-rhodium wire 38 in the X-axis direction and the Y-axis direction. Repeat the above steps to complete the welding of the platinum-rhodium mesh, and then cut off the power supply of all electrical equipment.

[0049] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific embodiments of the present invention are limited thereto.
