[0025] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments 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 clip positioning fixture 100 for positioning a button battery 01 , a positive spring clip 02 , and a negative spring clip 03 , so as to accurately weld the positive spring clip 02 and the negative spring clip 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 configured to be flipped over. The fixed clamping jaw 20 is fixedly mounted on the carrier mounting base 10, and the movable clamping jaw 30 is mounted on the carrier mounting base 10 so as to be movably moved 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 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 mounted on the carrier mounting base 10 so as to be movably moved 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. Positioning pins 42 for inserting and positioning the spring piece are installed on the front and rear sides of the adjustment portion 41 .
[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 electrode spring 03 is placed on the front side of the adjustment portion 41 and inserted into the positioning pin 42 to perform preliminary positioning of the negative electrode spring 03. The shape and position of the negative electrode spring 03 are then checked using a visual inspection device (such as a CCD). If the negative electrode spring 03 needs to be adjusted, the spring displacement block 40 is slid in the left and right directions, driving the negative electrode spring 03 to adjust its position and shape, so that the negative electrode spring 03 is accurately installed on the button battery 01 to avoid deformation caused by interference with the button battery 01. The negative electrode spring 03 can then be welded to the positive side of the button battery 01. Afterwards, the carrier mounting base 10 is operated to flip 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 perform preliminary positioning of 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 in the left and right directions to drive the positive spring piece 02 to adjust its 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. After that, the positive spring piece 02 can be welded to the back side of the button battery 01.
[0029] As mentioned above, after the positive and negative shrapnel 02 and 03 are installed on the positioning pins 42, the positive and negative shrapnel 02 and 03 have been preliminarily positioned. Before welding, the shrapnel displacement block 40 can also be translated in the left and right directions, thereby driving the positive and negative shrapnel 02 and 03 to accurately align with the button battery 01, avoiding the problem of corner warping and inaccurate placement causing inaccurate welding. In addition, the positive and negative shrapnel 02 and 03 are also provided with outwardly extending gold fingers 04, 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 each extend upwards over the carrier mounting base 10. At this point, the clamping cavity extends front to back. The adjustment portion 41 is located above the fixed clamping end 21 and the movable clamping end 31. The adjustment portion 41 does not interfere with the fixed clamping end 21 and the movable clamping end 31. Preferably, the adjustment portion 41 is a straight arm structure extending in the left-right direction to facilitate structural layout.
[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the movable jaw 30 and the shrapnel displacement block 40 are independently translatable, that is, the movements of the movable jaw 30 and the shrapnel 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 movable jaw 30 is installed on the first guide rail group 11, and the shrapnel displacement block 40 is installed on the second guide rail group 12. The movable jaw 30 is translated in the left-right direction on the carrier mounting base 10 through the first guide rail group 11, and the shrapnel displacement block 40 is translated in the left-right direction on the carrier mounting base 10 through the second guide rail group 12. The left-right translation of the movable jaw 30 is facilitated by the provision of the first guide rail group 11, and the left-right translation of the shrapnel displacement block 40 is facilitated by the provision of the second guide rail group 12.
[0032] like Figure 1 、 Figure 2 and Figure 4 As shown, the carrier mounting base 10 is equipped with a first return spring 13, which constantly pushes the movable jaw 30 toward the fixed jaw 20. The movable jaw 30 is operated to translate away from the fixed jaw 20 to place the button battery 01 into the clamping cavity. After the movable jaw 30 is released, the first return spring 13 causes the movable jaw 30 to translate toward the fixed jaw 20, and the movable jaw 30 and the fixed jaw 20 jointly clamp the button battery 01.
[0033] like Figures 1 to 4As shown, the button battery spring positioning fixture 100 of the present invention also includes a carrier flip seat 50. The carrier mounting base 10 is rotatably mounted to the carrier flip seat 50 via a rotating shaft 51, and the carrier flip seat 50 is flipped 180 degrees by the rotating shaft 51. Furthermore, the carrier flip seat 50 is provided with a mounting portion 52 and a first structural portion 53 and a second structural portion 54, respectively provided on the left and right sides of the mounting portion 52. The carrier mounting base 10 is also connected to a magnetic member 14. The first structural portion 53 is mounted with a plurality of magnets 55, and the second structural portion 54 is mounted with a plurality of magnets 55. The magnetic member 14 is located in front of the first structural portion 53 and is attracted by the magnets 55 on the first structural portion 53 to be positioned in the first structural portion 53. After the carrier flip seat 50 is flipped 180 degrees, the magnetic member 14 is located in front of the second structural portion 54 and is attracted by the magnets 55 on the second structural portion 54 to be positioned in the second structural portion 54. Magnets 55 are mounted on the first structural portion 53 and the second structural portion 54 to tightly attract the magnetic member 14 located in front of the magnets 55, thereby stably positioning the carrier mounting base 10. Preferably, the magnetic member 14 is a metal member, such as an iron plate or a metal plate.
[0034] like Figures 1 to 4 As shown, the button battery shrapnel positioning jig 100 of the present invention also includes a jig fine-shift slider 60 and a mounting bracket 70. The jig fine-shift slider 60 is mounted on the mounting bracket 70 so that it can slide left and right. The carrier flip seat 50 is mounted on the jig fine-shift slider 60. The mounting bracket 70 is equipped with a second return spring 71, which has a constant tendency to drive the jig fine-shift slider 60 to translate to the right. The jig fine-shift slider 60 can translate left and right on the mounting bracket 70, allowing the button battery shrapnel positioning jig 100 to be fine-tuned in the left and right directions to meet the needs of different workstations and working conditions.
[0035] The following briefly introduces the processing process of the button battery shrapnel positioning system of the utility model: Figure 8a As shown, the mobile clamping jaw 30 is moved away from the fixed clamping jaw 20 by a power source such as a cylinder, and the clamping cavity becomes larger. Figure 8b As shown, the manipulator grabs the button battery 01 and places it into the clamping chamber. After the cylinder retracts, under the action of the first return spring 13, the mobile clamping jaw 30 moves closer to the fixed clamping jaw 20, and the mobile clamping end 31 and the fixed clamping end 21 clamp the button battery 01 together. Figure 8c As shown, the spring displacement block 40 is driven by a driving device (such as a power source such as a motor) to move horizontally to the left and reach the discharge position. The robot absorbs the negative spring 03 and places it on the front side of the adjustment part 41 and inserts it into the positioning pin 42. Figure 8dAs shown, the button battery shrapnel positioning jig 100 is moved to the visual inspection device (such as a CCD device) under the action of the conveyor belt to take pictures and position the negative electrode shrapnel 03, and the shape and position information of the negative electrode shrapnel 03 are obtained. According to the obtained shape and position information, the driving device (such as a motor) is controlled to drive the shrapnel displacement block 40 to perform translation adjustment along the left and right directions (the direction indicated by the arrow k), so that the negative electrode shrapnel 03 is accurately buckled on the button battery 01. The button battery shrapnel positioning jig 100 is moved to the welding station under the action of the conveyor belt to weld the negative electrode shrapnel 03 to the button battery 01. Figure 8e As shown, the carrier flip seat 50 flips 180 degrees, and the spring displacement block 40 moves to the right under the drive of a power source such as a motor to reach the discharge position. The robot absorbs the positive spring 02 and places it on the rear side of the adjustment part 41 and inserts it into the positioning pin 42. Figure 8f As shown, the button battery spring clip positioning jig 100 is moved by a conveyor belt to a visual inspection device (e.g., a CCD device) for imaging and positioning. This information captures the morphological and positional information of the positive electrode spring clip 02. Based on this information, a drive device (e.g., a motor) is controlled to drive the spring clip displacement block 40 for translational adjustment in the left-right direction (in the direction indicated by arrow K) to accurately secure the positive electrode spring clip 02 to the button battery 01. The button battery spring clip positioning jig 100 is then moved by a conveyor belt to a welding station where the positive electrode spring clip 02 is welded to the button battery 01. Using a power source such as a pneumatic cylinder, the movable jaw 30 is translated away from the fixed jaw 20, enlarging the clamping cavity. The robot then removes the button battery 01 from the clamping cavity, completing the process. It should also be noted that after the negative electrode spring clip 03 is welded to the button battery 01, it disengages from the positioning pin 42.
[0036] exist Figure 1 and Figure 3 , the direction indicated by arrow X is from left to right, the direction indicated by arrow Y is from front to back, and the direction indicated by arrow Z is from bottom to top.
