Description

Technical Field

[0001] The utility model relates to the technical field of back clip welding, in particular to a back clip welding positioning jig. Background Art

[0002] Driven by mobile communication and multimedia technologies, the wide application of small electronic devices such as microphones and action cameras in various scenarios has put forward higher requirements for the portability and stability of the devices.

[0031] The carrying component 10 includes a base 11, a supporting member 12 installed in the middle of the top surface of the base 11, and a limiting member 13 installed on one side of the top end of the supporting member 12. Among them, a groove 14 is provided on the top surface of the base 11, and both the supporting member 12 and the limiting member 13 are located inside the groove 14.

[0032] In this embodiment, a placement cavity (not shown in the figure) is provided in the middle of the base 11 along its height direction, and the placement cavity is used to match and accommodate the installation of the supporting member 12. Among them, the top surface of the supporting member 12 is designed to be a curved surface profile. The top surface of the supporting member 12 on the side close to the limiting member 13 protrudes beyond the placement cavity, and the top surface of the supporting member 12 on the side far from the limiting member 13 is located inside the placement cavity, so as to better match the supporting clip 41. When supporting, one side of the clip 41 abuts against the limiting member 13, and the other side of the clip 41 abuts against the inner wall of the placement cavity, realizing the horizontal positioning of the clip 41.

[0033] The horizontal positioning component 20 includes a first horizontal positioning plate 21 installed at one end of the top surface of the base 11, a second horizontal positioning plate 22 for abutting against the first horizontal positioning plate 21, a horizontal positioning block 23 adjustably installed in the middle of the second horizontal positioning plate 22, and an intermediate rod 24 for passing through the second horizontal positioning plate 22. Among them, an avoidance cavity 221 is provided in the middle of the second horizontal positioning plate 22, and the avoidance cavity 221 is used to correspond to the supporting member 12; the horizontal positioning block 23 is installed inside the avoidance cavity 221, and the horizontal positioning block 23 is located on one side of the supporting member 12 to abut against one side of the elastic piece 42. A through hole 222 is provided on one side of the second horizontal positioning plate 22, and the through hole 222 communicates with the avoidance cavity 221 inward. After passing through the through hole 222, the intermediate rod 24 abuts against the side of the elastic piece 42 far from the horizontal positioning block 23, and the horizontal positioning of the elastic piece 42 is realized by using the intermediate rod 24 and the horizontal positioning block 23, thereby ensuring the horizontal relative position between the clip 41 and the elastic piece 42.

[0034] In this embodiment, both the first horizontal positioning plate 21 and the second horizontal positioning plate 22 are located inside the groove 14, which is beneficial to improving the accuracy of horizontal positioning. Magnets 25 are respectively installed on the relative two sides of the surface of the first horizontal positioning plate 21 facing the second horizontal positioning plate 22, and the second horizontal positioning plate 22 can be effectively adsorbed by using the magnets 25 to ensure the positioning stability of the elastic piece 42.

[0037] Please refer to again Figure 4 , in this embodiment, the rotary pressing rod 33 includes a rod body 331, a rotating shaft 332 vertically connecting one end of the rod body 331, and a spring 333 sleeved on the rotating shaft 332. Among them, the rotating shaft 332 is rotatably and telescopically connected to the base 11, the spring 33 is located inside the base 11, and the spring 33 is used to drive the rod body 331 to abut against the pressing rod 31 to achieve locking, so that the vertical positioning block 32 stably abuts against the elastic sheet 42.
