[0025] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figures 8a-8f As shown, the present invention discloses a button battery spring piece positioning fixture 100, which is used to position a button battery 01, a positive spring piece 02 and a negative spring piece 03, so as to accurately weld the positive spring piece 02 and the negative spring piece 03 to the front and back sides of the button battery 01.
[0027] The button battery shrapnel positioning fixture 100 of the present invention includes a carrier mounting base 10, a fixed clamping jaw 20, a movable clamping jaw 30 and a shrapnel displacement block 40. The carrier mounting base 10 is arranged to be flippable. The fixed clamping jaw 20 is fixedly mounted on the carrier mounting base 10, and the movable clamping jaw 30 is installed on the carrier mounting base 10 so as to be translatably movable in the left and right directions. The fixed clamping jaw 20 has a fixed clamping end 21, and the movable clamping jaw 30 has a movable clamping end 31. The fixed clamping end 21 and the movable clamping end 31 are arranged opposite to each other on the left and right, and the two enclose a clamping cavity (not marked) for clamping the button battery 01. The translation of the movable clamping jaw 30 in the left and right directions causes the clamping cavity to become larger or smaller accordingly. The shrapnel displacement block 40 is installed on the carrier mounting base 10 so as to be translatably movable in the left and right directions. The spring piece displacement block 40 is provided with an adjustment portion 41 extending toward one side of the clamping cavity, and the front side and the rear side of the adjustment portion 41 are provided with positioning pins 42 for inserting and positioning the spring piece.
[0028] During processing, the button battery 01 is placed in the clamping cavity, and the movable clamping end 31 of the movable clamping jaw 30 and the fixed clamping end 21 of the fixed clamping jaw 20 clamp the button battery 01. The negative spring piece 03 is placed on the front side of the adjustment part 41 and inserted into the positioning pin 42, and the negative spring piece 03 is preliminarily positioned. Then, the shape and position of the negative spring piece 03 are checked by a visual inspection device (such as CCD). If the negative spring piece 03 needs to be adjusted, the spring piece displacement block 40 slides in the left and right directions to drive the negative spring piece 03 to adjust the position and shape, so that the negative spring piece 03 is accurately installed on the button battery 01 to avoid deformation caused by interference with the button battery 01. After that, the negative spring piece 03 can be welded to the positive side of the button battery 01. After that, the carrier mounting base 10 is operated to turn over. Place the positive spring piece 02 on the rear side of the adjustment part 41 and insert it into the positioning pin 42 to preliminarily position the positive spring piece 02. Then, use a visual inspection device (such as CCD) to check the shape and position of the positive spring piece 02. If the positive spring piece 02 needs to be adjusted, the spring piece displacement block 40 slides along the left and right directions to drive the positive spring piece 02 to adjust the position and shape, so that the positive spring piece 02 can be accurately installed on the button battery 01 to avoid deformation caused by interference with the button battery 01. Then, the positive spring piece 02 can be welded to the back side of the button battery 01.
[0029] As mentioned above, after the positive spring piece 02 and the negative spring piece 03 are installed on the positioning pin 42, the positive spring piece 02 and the negative spring piece 03 have been preliminarily positioned. Before welding, the spring piece displacement block 40 can also be translated in the left and right directions, thereby driving the positive spring piece 02 and the negative spring piece 03 to accurately align with the button battery 01, avoiding the problem of inaccurate welding caused by the corners being lifted or the placement being inaccurate. In addition, the positive spring piece 02 and the negative spring piece 03 are also provided with gold fingers 04 extending outward, and the size of the gold fingers 04 also directly determines whether the welding is qualified. After the above adjustments, if Figure 5-7 As shown, the positive spring clip 02 and the negative spring clip 03 are placed in place and accurately positioned with the button battery 01. The distance A between the gold finger of the negative spring clip 03 and the center of the button battery 01, the distance B between the gold finger of the negative spring clip 03 and the top surface of the button battery 01, the distance C between the gold finger of the positive spring clip 02 and the center of the button battery 01, the distance D between the gold finger of the positive spring clip 02 and the bottom surface of the button battery 01, and the spacing E between the gold finger 04 of the positive spring clip 02 and the gold finger 04 of the negative spring clip 03 all meet the processing standards.
[0030] like Figure 1 , Figure 2 and Figure 3As shown, the fixed clamping end 21 and the movable clamping end 31 respectively pass upward over the carrier mounting base 10, and the clamping cavity penetrates front and back at this time, and the adjustment part 41 is arranged on the upper side of the fixed clamping end 21 and the movable clamping end 31, and the adjustment part 41 will not interfere with the fixed clamping end 21 and the movable clamping end 31. Preferably, the adjustment part 41 is a straight arm structure extending in the left-right direction to facilitate the structural arrangement.
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mobile jaw 30 and the spring displacement block 40 are independently translatable, that is, the movements of the mobile jaw 30 and the spring displacement block 40 are independent, have no connection with each other, and will not affect each other's movement. Specifically, the carrier mounting base 10 is installed with a first guide rail group 11 and a second guide rail group 12. The mobile jaw 30 is installed on the first guide rail group 11, and the spring displacement block 40 is installed on the second guide rail group 12. The mobile jaw 30 is translated along the left and right direction on the carrier mounting base 10 through the first guide rail group 11, and the spring displacement block 40 is translated along the left and right direction on the carrier mounting base 10 through the second guide rail group 12. The left and right translation of the mobile jaw 30 is facilitated by the first guide rail group 11, and the left and right translation of the spring displacement block 40 is facilitated by the second guide rail group 12.
[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the carrier mounting base 10 is installed with a first return spring 13, and the first return spring 13 always has a tendency to push the mobile clamping jaw 30 close to the fixed clamping jaw 20. The mobile clamping jaw 30 is operated to move away from the fixed clamping jaw 20, and the button battery 01 is placed in the clamping cavity. After the mobile clamping jaw 30 is relaxed, under the action of the first return spring 13, the mobile clamping jaw 30 moves close to the fixed clamping jaw 20, and the mobile clamping jaw 30 and the fixed clamping jaw 20 clamp the button battery 01 together.
