After welding is completed, the welding part needs to be quality inspected.

[0004] During the manual welding process of lead capacitor welding, the welding is manual loading. During manual loading, the leads need to be manually spread out, and then the product is placed between the leads with tweezers.

[0025] A rectangular docking plate 8 is fixedly connected to the rotating rod, and a pair of rectangular docking plates 8 are connected to the same rectangular plate 9. A rectangular pressing plate 10 is provided on the upper surface of the rectangular plate 9. A mounting bar 11 is also provided on the upper surface of the rectangular plate 9, and several semicircular open balls 12 with the same spacing are provided on the mounting bar 11.

[0026] When in use, first place the lead welding body 5 on the bottom surface of the rectangular loading plate 2, and then manually move the U-shaped limiting clamp 4. Because a pair of mutually symmetrical U-shaped limiting clamps 4 are provided on the bottom surface inside the rectangular loading plate 2, and the U-shaped limiting clamp 4 and the rectangular loading plate 2 are slidingly connected, and the U-shaped limiting clamp 4 has resilience. After manually moving the U-shaped limiting clamp 4, due to the resilience of the U-shaped limiting clamp 4, the U-shaped limiting clamp 4 will temporarily clamp the lead welding body 5, and then manually rotate the rectangular plate 9. Because a rectangular pressing plate 10 is provided on the upper surface of the rectangular plate 9, and a mounting bar 11 is also provided on the upper surface of the rectangular plate 9, and a number of semicircular opening balls 12 with the same spacing are provided on the mounting bar 11, when the rectangular plate 9 is rotated, the rectangular pressing plate 10 will press the lead welding body 5. At this time, a number of leads will be stretched out by a number of semicircular opening balls 12 with the same spacing, and then the products to be welded can be placed between the leads.

[0027] Example 2

[0028] Reference Figure 1 、 4 5 is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that a feeding device 13 is provided on one side of the heating copper block 1, and a plurality of rectangular feeding tubes 14 are provided inside the feeding device 13. A pair of rectangular storage frames 15 are connected through the upper surface of the rectangular feeding tubes 14.

[0029] A pair of U-shaped limit frames 16 are provided inside the rectangular feed tube 14, and a rectangular rod is provided between the pair of U-shaped limit frames 16. The lower surface of the rectangular feed tube 14 is connected to a rectangular guide frame 17. A rectangular baffle 18 is provided at the vertical surface of the pair of U-shaped limit frames 16, and the rectangular baffle 18 passes through the rectangular feed tube 14. The rectangular baffle 18 is connected to a rectangular extension plate 19. A rectangular docking block 20 is provided at the vertical surface on both sides of the rectangular extension plate 19, and the rectangular lower surface Hydraulic telescopic rods 21 are installed on the vertical surfaces on both sides of the material pipe 14, and L-shaped moving blocks 22 are provided on the vertical surfaces on both sides of the rectangular discharge pipe 14. Ball bearings are also provided on the bottom surface of the L-shaped moving block 22. The L-shaped moving block 22 is in contact with the operating desktop, and an L-shaped mounting plate is provided on the upper surface of the operating desktop. A guide round rod is provided between a pair of L-shaped mounting plates, and the guide round rod passes through the L-shaped moving block 22, and there is a sliding relationship between the L-shaped moving block 22 and the guide round rod.

[0030] When in use, first follow the operating steps in Example 1, because a pair of L-shaped mounting plates are provided with a guide rod, and the guide rod passes through the L-shaped moving block 22, and the L-shaped moving block 22 and the guide rod are in a sliding relationship, then manually pull the L-shaped moving block 22. When the L-shaped moving block 22 cannot move, do not let go, and then start a pair of hydraulic telescopic rods 21, because the extension rod of the hydraulic telescopic rod 21 is connected to the rectangular docking block 20, and the rectangular docking block 20 is connected to the rectangular extension plate 19, and the rectangular extension plate 19 is connected to several rectangular baffles 18. As the hydraulic telescopic rod 2 1 is started. At this time, among the pair of U-shaped limit frames 16, only the U-shaped limit frame 16 close to the hydraulic telescopic rod 21 has the product. As the extension rod of the hydraulic telescopic rod 21 retracts, the pair of U-shaped limit frames 16 will move toward the direction of the lead welding body 5. When moving to the cross-sectional opening at the upper end of the rectangular guide frame 17, because the product has no support, it will leak out of the rectangular guide frame 17 and eventually fall between the leads. After that, the hydraulic telescopic rod 21 can be stopped, and then the L-shaped moving block 22 can be reset. After that, the rectangular plate 9 can be reset and the welding process can be carried out.

[0031] The remaining structures are the same as those of Example 1.
