Description

Technical Field

[0001] This utility model relates to the field of fuse manufacturing technology, and in particular to a fuse end cap pressing device. Background Technology

[0002] A fuse is an essential electronic component in a circuit system, primarily serving as an overload protection device. When a fuse is correctly installed in a circuit, it will melt and break the circuit when the current abnormally rises to a certain level or temperature, thus protecting the circuit's safe operation and preventing dangers such as fires caused by overheating.

[0003] In the fuse manufacturing process, refer to Figure 1 After the fuse 7 is filled with sand, the end caps 71 at both ends of the fuse 7 need to be sealed with copper caps 72 by riveting the sand filling holes 711 on the end caps 71. The copper caps 72 can be cylindrical structures with one end open and the other end having a conical protrusion. Since both ends of the fuse need to be connected to end caps, sand filling only needs to be done through the sand filling hole on one end cap, and the end cap on the other end needs to be sealed. However, the end caps are all uniformly produced from the same mold, and the end cap on the non-sand-filled end needs to have its sand filling hole sealed. Therefore, it is necessary to perform a copper cap pressing operation on the sand filling holes on some end caps. In addition, some fuses need to be cured after sand filling (for fuses that do not need to be cured, the end cap or copper cap can be sealed). Curing requires the passage of some air, so a complete seal cannot be used. Therefore, a copper cap with a gap (there is a gap at the bottom of the cap) can be used. Thus, it is necessary to rivet the gap copper caps separately for the sand filling holes of some end caps to avoid the need to open two sets of molds to produce different end caps, which would be more costly and would not allow for flexible selection during the production process.

[0004] Furthermore, the existing copper cap pressing operation requires manual operation. Workers place the end cap on the workbench, manually pick up the smaller copper cap, align the conical protrusion with the sand-filling hole on the end cap, and then operate the lever of the manual riveting machine to slowly lower the pressing pin, align it with the copper cap, and then rivet it tightly to the sand-filling hole on the end cap. The existing pressing operation is inefficient and labor-intensive, leading to increased fuse production costs and reduced product competitiveness. In addition, the existing pressing equipment can only press end caps on fuses that have already been sand-filled; pressing end caps on the other end requires custom-made caps, which is costly. Modifying only the existing pressing equipment could significantly reduce costs. This case arises from this. Utility Model Content

[0018] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0019] Combination Figures 2 to 7 As shown, this utility model discloses a fuse end cap pressing device, which includes an X-axis linear module 1 and a Z-axis linear module 2, a copper cap feeding device 3, an automatic pressing device 4, an end cap fixing device 5, and an end cap feeding device 6. The X-axis linear module 1 is connected to the Z-axis linear module 2 and is used to drive the Z-axis linear module 2 to move left and right along the X-axis direction. The end cap feeding device 6, the end cap fixing device 5, the copper cap feeding device 3, and the automatic pressing device 4 are located on the same axis and are parallel to each other in front of the X-axis linear module 1.

[0020] The end cap fixing device 5 is used to fix the end cap 71. The copper cap feeding device 3 is used to output the copper cap 72 with its opening facing upwards. The end cap feeding device 6 includes an end cap storage assembly 61 for placing the end cap 71 and an end cap transfer assembly that can transfer the end caps 71 one by one from the end cap storage assembly to the end cap fixing device 5. In this embodiment, the end cap transfer assembly is a suction cup assembly 62 that can pick up and put down the end caps 71. The suction cup assembly 62 is provided with at least two suction cups 621 that can simultaneously pick up the end caps 71. Considering that the end caps 71 have a certain weight, the suction cup assembly in this embodiment is provided with three suction cups 621.

[0021] The automatic riveting device 4 and the suction cup assembly 62 are located above the end cap fixing device 5. The automatic riveting device 4 and the suction cup assembly 62 are connected side by side to the Z-axis linear module 2 and move up and down along the Z-axis in the Z-axis linear module 2. In this embodiment, the automatic riveting device 4 and the suction cup assembly 62 are connected side by side to the Z-axis module mounting plate 21 of the Z-axis linear module 2. The automatic riveting device 4 and the suction cup assembly 62 are independently set on the Z-axis module mounting plate 21. When the Z-axis module mounting plate 21 receives a drive command, it realizes a lifting and lowering movement. The suction cup assembly 62 can pick up the end cap from the end cap storage assembly 61 and put it into the end cap fixing device 5. The automatic riveting device 4 can adsorb the copper cap onto the end cap and then perform riveting. In this embodiment, the X-axis linear module 1 and Z-axis linear module 2, the copper cap feeding device 3, the automatic riveting device 4, the end cap fixing device 5, and the end cap feeding device 6 are all mounted on a platform 81. The platform 81 is located on the top of a cabinet 82, and the X-axis linear module 1 is mounted on a gantry frame 83 fixed on the platform. The automatic riveting device 4 includes a cap-pressing pin 41. The automatic riveting device 4 moves up and down, causing the cap-pressing pin 41 to extend vertically into the opening of the copper cap 72 and near the sand-filling hole 711 of the end cap 71. The cap-pressing pin 41 is used to absorb and remove the copper cap 72 from the copper cap feeding device 3 and to rivet and fix the copper cap 72 to the sand-filling hole 711 of the end cap 71.

[0022] Furthermore, the device may also include an end cap storage box 9 for storing the end cap 71 after it has been capped. The end cap 71 after being capped in the end cap fixing device 5 is transferred to the end cap storage box 9 by the suction cup assembly 62. The end cap storage box 9 is located outside the end cap storage assembly 61. The end cap fixing device 5, the end cap storage assembly 61, and the end cap storage box 9 are located on the same axis and are all located below the suction cup assembly 62, so that the end cap can be picked up and lowered by the suction cup assembly.

[0023] The end cap fixing device 5 includes an end cap placement platform 52 on a base 51. The end cap 71 is placed on one side of the end cap placement platform 52 and is enclosed on that side. The other side of the end cap placement platform 52 is provided with a limiting member 53 that can lock and limit the end cap 71. In this embodiment, the limiting member 53 includes a support frame 531, a locking block 532, and a top holding member 533. The support frame 531 is supported on one side of the base 51. The front end of the locking block 532 faces the end cap 71 on the end cap placement platform 52. The top holding member 533 is fixed on the support frame 531. The locking block 532 locks the end cap 71 with the help of the top holding member 533. After being locked, the end cap 71 is limited on the end cap placement platform 52. The top support 533 can be a push cylinder. In this embodiment, the end cap 71 is square, and a square limiting groove 521 is formed in the top surface of the end cap placement platform 52. One corner of the end cap 71 is inserted into one side of the end cap placement platform 52, and this corner of the end cap 71 is blocked. The limiting member 53 is located opposite the corner of the end cap 71 that has been inserted. The front end of the locking block 532 forms a locking edge that allows the corner of the end cap 71 to be locked into it. Figure 8 As shown, a flange 712 is formed by extending downward from the outer periphery of one end face of the end cap 71. A groove 522 is provided in the bottom surface of the limiting groove 521 to allow the flange 712 to be inserted, so as to keep the end cap 71 flat on the end cap placement platform 52 and ensure the smooth operation of the cap pressing action.

[0024] In this embodiment, the end cap storage assembly 61 includes a limiting component and a lifting mechanism. The limiting component includes two limiting strips 611. A through hole (not shown in the figure) is provided on the platform 81. The two limiting strips 611 pass through the mounting hole and are fixed to a mounting block 612. The mounting block 612 is fixed to the platform 81. The end cap 71 passes through the two limiting strips 611 and is located inside the two limiting strips 611. In this embodiment, the through hole is a square hole with an area larger than the area of ​​the end cap. The limiting strips 611 are strips with bent corners in their cross-section. After the two limiting strips 611 are inserted into the through hole, the end cap 71 can pass through and be limited by both sides between the two limiting strips 611, so that the end cap 71, when stacked, is located between the two limiting strips 611. The limiting strips are fixed to the platform by the mounting block 612. The limiting strips 611 or the mounting block 612 can be adjusted appropriately to accommodate end caps 71 of different specifications. A lifting mechanism is located below the platform 81. A certain number of end caps 71 can be stacked and positioned between two limiting strips 611. The lifting mechanism is used to gradually push the stacked end caps 71 upwards, so that the suction cup assembly 62 can smoothly suck the end caps into the end cap fixing device 5. In this embodiment, as shown... Figure 6As shown, the lifting mechanism includes a support guide frame 613, a stepper motor 614, a lead screw 615, and a slider 616 mounted on the lead screw 615. The support guide frame 613 includes a base plate 6131 fixed below the platform 81 and multiple guide posts 6132. The stepper motor 614 is mounted on the base plate 6131. ​​The lead screw is located between the multiple guide posts 6132, and the lead screw 615 and the slider 616 are located between two limiting plates 611. The end cap 71 is stacked and located on the slider 616 and between the two limiting plates 611. The driven lead screw 615 can drive the slider 616 to move upward, thereby gradually pushing the end cap 71 on the slider 616 upward.

[0025] The copper cap feeding device 3 includes a rotary selection mechanism 31 and a swing suction mechanism 32. The rotary selection mechanism 31 includes a cap box 311, a rotating blade 312, and a rotary motor 313. The cap box 311 is used to hold a plurality of copper caps. The rotary motor 313 drives the rotating blade 312 to rotate. The end of the rotating blade 312 has a copper cap seat 314 arranged along the rotation direction. The copper cap seat 314 rotates through the cap box 311 with the rotating blade 312, and the size of the copper cap seat 314 matches the opening of the copper cap 72. Thus, when the rotating blade 312 rotates through the cap box 311, the copper cap seat 314 can randomly extend into the opening of a copper cap 72 for locking. The continuing to rotate rotating blade 312 uses the copper cap seat 314 to carry the copper cap 72 away from the cap box 311 for adsorption by the swing suction mechanism 32 described below. Figure 3 or Figure 7 As shown, the cap box 311 has an arc-shaped groove 3111 to facilitate the collection of copper caps 72, making it easier for the copper cap seat 314 of the rotating blade 312 to clamp the copper caps 72, and also improving the clamping success rate.

[0026] The oscillating suction mechanism 32 includes an oscillating cylinder 321 and an oscillating suction cap rod 322. One end of the oscillating suction cap rod 322 is connected to the oscillating cylinder 321, and the other end has a copper cap adsorption groove 323, which is used to accommodate and adsorb the copper cap 72. The oscillating suction cap rod 322 is driven by the oscillating cylinder 321 to oscillate and approach the copper cap seat 314 to adsorb the copper cap 72. After the oscillating suction cap rod 322 returns to its original position, it places the copper cap 72 in an open-facing state. In this embodiment, the oscillating suction mechanism 32 and the rotary material selection mechanism 31 are arranged side by side, with the oscillating suction mechanism 32 being closer to the end cap 71 of the end cap fixing device 5 than the rotary material selection mechanism 31.

[0027] Both the cap-pressing pin 41 and the swinging cap-suction rod 322 are connected to a negative pressure device. The swinging cap-suction rod 322 may have a negative pressure channel (not shown in the figure). One end of the negative pressure channel is connected to the copper cap adsorption groove 323, and the other end is connected to the negative pressure device. This allows the copper cap adsorption groove 323 to have a negative pressure adsorption function. When the swinging cap-suction rod 322 swings, the copper cap adsorption groove 323 can flip over and cover the copper cap 72 of the copper cap seat 314, then adsorb and fix the copper cap 72 into the copper cap adsorption groove 323. After the swinging cap-suction rod 322 swings and resets, the copper cap 72 moves with the copper cap adsorption groove 323 closer to the end cap fixing device 5 and remains in an open-facing state, so that the cap-pressing pin 41 of the aforementioned automatic riveting device can adsorb the copper cap 72. In this embodiment, the bottom surface of the cap-pressing needle 41 may be provided with a negative pressure opening (not shown in the figure), and the negative pressure opening head is also connected to the negative pressure device. Thus, when the cap-pressing needle 41 is inserted into the opening of the copper cap 72 in the copper cap adsorption groove 323, the negative pressure suction of the copper cap adsorption groove 323 is closed while the negative pressure suction of the cap-pressing needle 41 is turned on, so that the copper cap 72 can be adsorbed onto the cap-pressing needle 41.

[0028] With the above structure, when the fuse end cap crimping equipment of this utility model is working, the suction cup assembly 62 in the end cap feeding device 6 first picks up the end cap 71 in the end cap storage assembly 61 and moves it to the end cap fixing device 5 (after the end cap 71 in the end cap storage assembly 61 is picked up, the end cap 71 can be pushed up again by the lifting mechanism to facilitate the next suction). The end cap 71 to be crimped is fixed in the end cap fixing device 5 by the limiting member 53, while the copper cap feeding device 3 automatically outputs the copper cap 72 with the opening facing upward, and keeps the sand filling hole 711 of the end cap 71, the copper cap 72 with the opening facing upward and the crimping pin 41 in the same straight line. Using the rotating material selection mechanism 31 and the swing suction mechanism 32, the copper cap 72 can be positioned directly below the crimping pin 41 of the automatic crimping device 4. Then, the Z-axis linear module drives the process. The automatic riveting device 4 moves downward to allow the capping pin 41 to adhere to the copper cap 72. Then, the copper cap 72 moves upward away from the copper cap feeding device 3 and is positioned above the end cap 71 fixed on the end cap fixing device 5. The X-axis linear module then operates again to drive the capping pin 41 of the automatic riveting device 4, so that the capping pin 41 and the copper cap 72 are aligned with the sand filling hole 711 of the end cap 71. Then, the capping pin 41 lowers with the copper cap 72, placing the copper cap 72 into the sand filling hole 711. At the same time, the automatic riveting device drives the capping pin 41 to move downward to rivet and fix the copper cap in the sand filling hole, thus completing the fuse capping operation. Finally, the suction cup assembly 62 is used to adhere the capped end cap into the end cap storage box 9. This cycle is repeated to realize the automated operation of fuse capping, which can effectively improve production efficiency and reduce labor costs.

[0029] In addition, the end cap pressing device of this utility model can be modified and adjusted from the fuse pressing device. For example, the X-axis linear module 1 and Z-axis linear module 2, copper cap feeding device 3, and automatic riveting device 4 can be reused from the existing fuse end cap pressing device. Only some mechanisms need to be slightly adjusted (for example, the automatic riveting device 4 is retained on the Z-axis linear module 2 and a suction cup assembly 62 is added). Then, the end cap fixing device 5 and the end cap feeding device 6 are added to reassemble and form a pressing device that can be used for the other end cap, thus saving equipment costs.

[0030] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.

The copper cap seat passes through the cap box as the rotating blade rotates, and the size of the copper cap seat matches the opening of the copper cap. The swing suction mechanism includes a swing cylinder and a swing suction rod. One end of the swing suction rod is connected to the swing cylinder, and the other end has a copper cap adsorption groove, which is used to accommodate and adsorb copper caps. The swing suction rod is driven by the swing cylinder to swing and approach the copper cap seat to adsorb the copper caps. After the swing suction rod returns to its original position, it places the copper caps in an opening-up state.
