Description

Technical Field

[0001] This utility model relates to the field of fuse processing technology, specifically a forming and cutting machine for battery protection board fuses. Background Technology

[0002] The battery protection board protects the battery during charging and discharging, and includes fuses, a switching circuit, and an overvoltage protection chip. When the battery voltage exceeds a certain value, the overvoltage protection chip controls the switching circuit to conduct, grounding the fuse to reduce the voltage at the cell connection terminals and the current through the fuse. Continued overcharging eventually causes the fuse to blow, thus protecting the battery from overcharging. The fuse also needs to be deformed after manufacturing to facilitate installation.

[0003] In the current fuse manufacturing process, the fuse is typically cut to the required length using a shearing device, and then bent into shape using a forming device. However, because the bent fuse is tightly embedded in the bending die of the forming device, it needs to be manually removed from the die after the bending operation is completed. This method is not only time-consuming and labor-intensive, resulting in low efficiency, but it also easily damages the fuse, causing product quality problems. Summary of the Invention

[0004] The purpose of this invention is to provide a forming and cutting machine for battery protection board fuses, which can remove all fuses at once, with high work efficiency and less risk of damaging the fuses, thereby solving the problems of low efficiency and easy damage to fuses in the existing fuse removal methods mentioned in the background art.

[0020] Please see Figure 1-3 A forming and shearing machine for battery protection board fuses includes a base 1, a support column 2, and a support platform 3. The support column 2 is erected on one side of the top surface of the base 1, and the support platform 3 is connected to the top of the support column 2. A lower bending die 4 is provided in the middle of the top surface of the base 1, and an upper bending die 5, which can move up and down, is provided below the support platform 3, opposite to the lower bending die 4. A driving mechanism 6 is provided on the support platform 3 for driving the upper bending die 5 to rise and fall. A receiving groove 41 is formed on the top surface of the lower bending die 4 along its length. Protrusions 42 are formed on the top surfaces of the lower bending die 4 on both sides of the receiving groove 41, and grooves 51 that fit the protrusions 42 are formed on the bottom surface of the upper bending die 5. A plurality of bending grooves 43 are arranged at equal intervals on the top surface of the lower bending die 4, and an ejection mechanism 7 for ejecting the fuse from the bending groove 43 is provided in the receiving groove 41.

[0021] In this embodiment, both the protrusion 42 and the groove 51 are conical, and the bending groove 43 is conical at the position of the protrusion 42; the bending groove 43 extends into the receiving groove 41.

[0022] Please see Figure 1-2During bending, the fuse is first placed on the lower bending die 4, with the fuse leads positioned in the bending groove 43 and the fuse body positioned above the receiving groove 41. Then, the drive mechanism 6 drives the upper bending die 5 downwards until it closes with the lower bending die 4, bending the fuse leads into the appropriate shape. After bending, the drive mechanism 6 drives the upper bending die 5 upwards until it completely separates from the lower bending die 4. Please refer to [link to relevant documentation]. Figure 3 Then, all fuses can be ejected from the bending groove 43 by the ejection mechanism 7; this utility model can remove all fuses at once and is not easy to damage the fuses, which greatly improves work efficiency.

[0023] Please see Figure 1-2 The driving mechanism 6 includes a lifting plate 61, a mounting block 62, two shearing plates 63, and a first cylinder 64. The lifting plate 61 is vertically mounted below the support platform 3. The mounting block 62 is connected to the bottom surface of the lifting plate 61. The two shearing plates 63 are arranged opposite each other on both sides of the mounting block 62. The bending upper die 5 is movably mounted between the two shearing plates 63. The first cylinder 64 is mounted on the support platform 3, with one end connected downward to the lifting plate 61, for driving the lifting plate 61 to rise and fall.

[0024] The shearing plate 63 and the edge of the bending lower die 4 are staggered vertically. When the shearing plate 63 descends with the lifting plate 61 to the position of the bending lower die 4, the shearing plate 63 works with the edge of the bending lower die 4 to cut off the fuse pins. This cuts off the pins while the fuse is being bent, without having to cut off the excess pins after the pins are bent, thus improving work efficiency.

[0025] Please see Figure 1-2 The shearing plate 63 has two opposing guide grooves 631 along the vertical direction. The bending upper die 5 has guide shafts 52 connected to its two sides, which are movably disposed within the guide grooves 631. Through the cooperation of the guide shafts 52 and the guide grooves 631, the bending upper die 5 can stably rise and fall between the two shearing plates 63. In this embodiment, a limiting protrusion ring is formed on the outer circumferential surface of the guide shaft 52 extending beyond the shearing plate 63. The limiting protrusion ring serves to position the bending upper die 5.

[0026] The drive mechanism 6 includes two slide rods 65 and two springs 66. The two slide rods 65 are arranged opposite each other at the bottom of the mounting block 62 and perpendicular to the bottom surface of the mounting block 62. The bending upper die 5 is slidably mounted on the two slide rods 65. The spring 66 is sleeved on the slide rod 65, with one end of the spring 66 connected upward to the bottom surface of the mounting block 62 and the other end connected downward to the top surface of the bending upper die 5. The bottom surface of the mounting block 62 is provided with two opposing limiting blocks 67 to limit the distance the bending upper die 5 moves towards the mounting block 62.

[0027] During bending, the first cylinder 64 drives the lifting plate 61, mounting block 62, two shearing plates 63, and bending upper die 5 to press down. When the bending upper die 5 and bending lower die 4 are closed, the two shearing plates 63 continue to descend, working with the edge of the bending lower die 4 to cut off the fuse pin. Meanwhile, the bending upper die 5 continuously compresses the spring 66 during this process. When the two limit blocks 67 at the bottom of the mounting block 62 press against the top surface of the bending upper die 5, the bending upper die 5 works with the bending lower die 4 to bend the fuse pin. Then, the first cylinder 64 drives the lifting plate 61, mounting block 62, two shearing plates 63, and bending upper die 5 to rise, thus opening the die.

[0028] In this embodiment, protrusions 44 are formed on both sides of the receiving groove 41 on the top surface of the lower bending die 4, and a limiting groove 53 adapted to the protrusions 44 is provided on the bottom surface of the upper bending die 5; the upper bending die 5 and the lower bending die 4 are accurately closed by the cooperation of the protrusions 44 and the limiting groove 53.

[0029] Please see Figure 1 Two guide rods 11 are arranged opposite each other on the base 1, and the lifting plate 61 is movably arranged on the two guide rods 11 in the vertical direction.

[0030] Please see Figure 1-2 The ejection mechanism 7 includes a hinge seat 71, an ejector rod 72, and a second cylinder 73. A step 45 is provided on one edge of the top surface of the lower bending die 4. The hinge seat 71 is installed on the bottom wall of the step 45. One end of the ejector rod 72 is hinged to the hinge seat 71, and the other end passes through the receiving groove 41 and is hinged to the piston rod of the second cylinder 73. The end of the second cylinder 73 away from the ejector rod 72 is hinged to the base 1.

[0031] Please see Figure 3 After the fuse lead is cut off and formed, the bending upper die 5 moves upward to open the mold. At this time, the second cylinder 73 can be activated. The second cylinder 73 drives the ejector rod 72 to swing upward around the hinge point with the hinge seat 71 towards the receiving groove 41. During the swinging process, the ejector rod 72 pushes the fuse upward so that the fuse lead is disengaged from the bending groove 43. Then the fuse slides downward along the axial direction of the ejector rod 72 to complete the discharge. Finally, the second cylinder 73 drives the ejector rod 72 to reset.

[0032] Please see Figure 1-2A finished product frame 8 is provided below the end of the push rod 72 near the hinge seat 71. The finished product frame 8 is mounted on the base 1 and is used to receive the fuse that slides down from the push rod 72. In this embodiment, the bottom surface and inner wall of the finished product frame 8 are covered with a sponge layer to prevent the surface of the fuse from being damaged by impact with the finished product frame 8 when it is being cut. Inclined receiving plates 9 are provided on both sides of the bending lower die 4. A waste frame 10 is provided on one side of the finished product frame 8. The bottom end of the receiving plate 9 extends into the waste frame 10. The receiving plate 9 is used to receive the cut lead waste, and the waste frame 10 is used to collect the lead waste.
