[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Figure 1 The structure of a manual joint welding jig (without elbow clamp) according to an embodiment of the present application is shown schematically, Figure 2 The structure of the jig upper plate in Figure 1 is shown, Figure 3 The structure of the jig lower plate in Figure 1 is shown, Figure 4 The top perspective structure of the manual joint welding jig (with elbow clamp) in Figure 1 when closed is shown, Figure 5 The side view structure of the manual joint welding jig in Figure 4 when closed is shown. As shown in Figures 1-5 , the jig comprises a jig upper plate 1, a jig lower plate 2, a base plate 3 and an elbow clamp 4, wherein one side of the jig upper plate 1 and the jig lower plate 2 are movably connected by a hinge 14, the jig upper plate 1 can be turned to close with the jig lower plate 2, that is, the bottom surface of the jig upper plate 1 is attached to the top surface of the jig lower plate 2. The jig lower plate 2 and the elbow clamp 4 are both installed on a base plate 3, and one end of the elbow clamp 4 is above the jig lower plate 2, which can clamp the closed jig upper plate 1 and jig lower plate 2.

[0023] Preferably, the jig upper plate 1 and the jig lower plate 2 are both made of stainless steel, and other suitable materials for making the jig can also be selected according to the situation.

[0024] Two protruding pressing blocks 11 are formed side by side on the bottom surface of the jig upper plate 1, the pressing blocks 11 are roughly square, and a through laser guide hole 12 is provided on each pressing block 11. The laser guide hole 12 is through, which is used to guide the direction of the laser, when the jig upper plate 1 and the jig lower plate 2 are closed, the laser is used to pass through the laser guide hole 12, then the welding can be carried out at the accurate position.

[0025] A groove 23 is formed in the middle of the top surface of the jig lower plate 2, the width of the groove 23 is roughly equal to the width of the material belt 5 to be welded. Upward protruding bosses 24 are formed on both sides inside the groove 23, wherein the height of the bosses 24 is not higher than the part of the top surface of the jig lower plate 2 without the groove 23.

[0026] A row of guide pins 21 is provided on the bosses 24 on both sides inside the groove 23 on the top surface of the jig lower plate 2, the height of the two rows of guide pins 21 is higher than the top surface of the jig lower plate 2. Therefore, in order to ensure that the jig upper plate 1 and the jig lower plate 2 can be closed smoothly, two rows of pin holes 13 are provided on the bottom surface of the jig upper plate 1, and the two rows of pin holes 13 correspond to the two rows of guide pins 21 respectively, that is, when the jig upper plate 1 and the jig lower plate 2 are closed, the two rows of guide pins 21 can be inserted into the two rows of pin holes 13.

[0027] Two welding blocks 22 are also installed on the top surface of the lower jig plate 2, and the two welding blocks 22 respectively pass through the middle of the two protrusions 24 on the inside of the groove 23, and separate the row of guide pins 21 on the protrusions 24 at both ends. Among them, respectively corresponding to the two pressing blocks 11 and the laser guide holes 12 thereon, that is, when the upper jig plate 1 and the lower jig plate 2 are closed, the two pressing blocks 11 and the laser guide holes 12 thereon are respectively located directly above the two welding blocks 22.

[0028] Preferably, the welding block 22 is slightly higher than the protrusion 24, so that when the upper jig plate 1 and the lower jig plate 2 are closed, the pressing block 11 can be tightly pressed with the welding block 22.

[0029] The elbow clamp 4 is installed on a bottom plate 3 through a pad 41. Specifically, the pad 41 is installed on the bottom plate 3 and does not contact the lower jig plate 2, and the elbow clamp 4 is installed above the pad 41. Among them, the two ends of the elbow clamp 4 are the pressing part 42 and the holding part 43, and the pressing part 42 extends above the lower jig plate 2.
