It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0016] A welding jig ejection mechanism includes a welding jig and an ejection structure 2. A first special-shaped small part a1 and a second special-shaped small part a2 are placed in the welding jig 1 and fixed. The welding mechanism welds the first special-shaped small part a1 and the second special-shaped small part a2 in the welding jig 1 together. Then an external manipulator opens the welding jig 1 and places it on the ejection structure 2. The welding jig 1 moves along the ejection structure 2 to eject the special-shaped small part after welding, so as to realize the ejection and material removal of the special-shaped small part.
[0017] The welding jig 1 includes a jig body 11, a pressure block 12, a first clamping block 13, a second clamping block 14, a third clamping block 15, a fourth clamping block 16, a first fixed penetrating rod 17 and a second fixed penetrating rod 18. The pressure block 12 is hingedly arranged on the jig body 11, so that the first special-shaped small piece a1 and the second special-shaped small piece a2 can be placed on the jig body 11 and pressed and fixed to prevent the first special-shaped small piece a1 and the second special-shaped small piece a2 from moving during welding to ensure welding accuracy. The first clamping block 13, the second clamping block 14, the third clamping block 15 and the fourth clamping block 16 are all inserted into the jig body 11, the first clamping block 13 and the third clamping block 15 are inserted into the jig body 11 from the side of the jig body 11, the second clamping block 14 and the fourth clamping block 16 are inserted into the jig body 11 from the top of the jig body 11, the first fixed penetrating rod 17 and the second fixed penetrating rod 18 are inserted into the jig body 11, and the first fixed penetrating rod 17 passes through the second clamping block 14, and the second fixed penetrating rod 18 passes through the first clamping block 13 and the third clamping block 15 to fix the first clamping block 13, the second clamping block 14 and the third clamping block 15. The first clamping block 13, the second clamping block 14, the third clamping block 15 and the fourth clamping block 16 are all special-shaped blocks. The fixture body 11 is matched with the first clamping block 13, the second clamping block 14, the third clamping block 15 and the fourth clamping block 16 to achieve foolproofing. A clamping space 19 for placing special-shaped small parts is formed between the first clamping block 13, the second clamping block 14, the third clamping block 15 and the fourth clamping block 16 and the fixture body 11, thereby fixing the first special-shaped small part a1 and the second special-shaped small part a2. The fixture body 11 is provided with a first magnet 111 and a positioning column 112. The positioning column 1 12 is arranged on one side of the clamping space 19, and is used to fix the first special-shaped small part a1. The first magnet 111 is fixed on the jig body 11, and the first magnet 111 is magnetically connected to the pressure block 12. The pressure block 12 is provided with a second magnet 121 and a welding hole 122. The second magnet 121 is fixed on the pressure block 12, and the second magnet 121 is magnetically connected to the jig body 11. The welding hole 122 is aligned with the welding position between the first special-shaped small part a1 and the second special-shaped small part a2, so that the welding mechanism can weld the first special-shaped small part a1 and the second special-shaped small part a2.
[0018] The ejection structure 2 includes a base 21, a guide rod 22 and a ejector rod 23. The guide rod 22 is arranged on the base 21 in an orderly manner, and the guide rod 22 is arranged around the four corners of the jig body 11 to fix the welding jig 1. The ejector rod 23 is arranged in the middle of the base 21 to eject the special-shaped small parts located in the welding jig 1. The lower end of the jig body 11 is inclined, which is used to adjust the welding angle to facilitate welding by the welding mechanism. The base 2 is provided with a ramp 24 that matches the lower end surface of the jig body 11, so that the upper end of the jig body 1 remains horizontal during ejection. The upper end of the ejector pin 23 is provided with a protrusion 231 and a groove 232, which are arranged adjacent to each other. When ejection is required, the protrusion 231 first contacts the special-shaped small part, so that the special-shaped small part is first ejected from the positioning column 112, and then the groove 232 contacts the special-shaped small part, so that the special-shaped small part is ejected from the jig body 1, thereby realizing the ejection of the special-shaped small part.
