Description

Technical fields:

[0001] This utility model relates to the technical field of wire processing equipment, and specifically to a top rod triggering structure for a terminal block machine. Background technology:

[0002] Currently, the use of wires is increasing, and the variety of types is also growing. As the lifespan of electrical equipment increases, the requirements for wire quality are also rising, leading to a surge in demand. In the production process, it is often necessary to combine wires of different thicknesses and then crimp them together with terminals to meet specific applications. Such combined wires are convenient to use and have a long service life. Previously, the production of these combined wires was done manually, but this method was inefficient and produced suboptimal quality, gradually failing to meet the demands of mass production. Consequently, it was gradually replaced by automated wire processing equipment.

[0003] Currently available wire processing equipment can automatically strip and twist wires. For example, Chinese utility model patent application CN201556831U discloses a novel pneumatic stripping and twisting machine, which includes: a frame, an upper template, and a lower template; the upper template is equipped with an upper knife holder and an upper wire clamping block movably connected to the upper template, and an upper knife is mounted on the upper knife holder; the lower template is equipped with a lower knife holder, which is connected to the lower template via a pressure plate slide rail, and a lower knife is mounted on the lower knife holder; the upper knife holder and the lower knife holder are connected by guide pillars; the frame has a first cylinder and a second cylinder respectively connected to the upper wire clamping block and the upper template; a third cylinder is also connected to the lower knife holder at the rear of the frame.

[0004] However, this existing structure still has the following shortcomings:

[0005] In this technical solution, three cylinders work simultaneously to drive the upper and lower cutter holders to strip the wire and drive the twisting tool to twist it, completing the stripping and twisting of the wire in one go. However, this technical solution does not have a triggering structure, which results in inconsistent wire lengths each time, and the processing accuracy needs to be improved. In addition, the upper and lower cutter holders and the upper and lower templates are all exposed, making it easy for operators to be pinched and injured during operation.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figures 1 to 6 The diagram shows a top rod triggering structure for a terminal crimping machine, comprising: a base plate 1; a wire clamping module 2 disposed on the base plate 1 for inserting wires; a wire twisting module 3 disposed on the base plate 1 for stripping and twisting wires; and a sliding motor module 5 disposed on the base plate 1 for driving the wire twisting module 3 to slide. The wire twisting module 3 contains a wire clamp assembly 31 for clamping wires and a top rod triggering switch 41 for detecting whether the wire is in position. The top rod triggering switch 41 includes a fixed sleeve 411 passing through the rotation center of the wire clamp assembly 31; a retractable sensing rod 412 passing through the fixed sleeve 411; a sensing switch 413 disposed on the wire twisting module 3 for detecting whether the sensing rod 412 has shifted; and a reset motor 414 tractably connected to the sensing rod 412 for driving the sensing rod 412 to reset.

[0026] In this invention, a top rod trigger switch 41 is installed inside the twisting module 3. During operation, the wire is inserted from outside the equipment through the wire clamping module 2 and touches the sensing rod 412 of the top rod trigger switch 41. Once triggered, the wire clamping assembly 31 clamps the wire, and the twisting module 3 strips and twists the wire, effectively improving the processing accuracy and efficiency of the equipment. Furthermore, the operator's hands do not need to be close to the twisting module 3, so they will not be pinched, effectively improving work safety.

[0027] Combination Figure 2 and Figure 3 As shown, in this utility model, the wire clamping module 2 drives the first clamping block 24 and the second clamping block 25 to move inward together through the specially shaped transmission plate 27, thereby generating a clamping action. Specifically, the wire clamping module 2 includes a wire clamping motor 21 mounted on a base plate 1, a fixed support frame 22 mounted on the base plate 1, a wire clamping seat 23 mounted on the fixed support frame 22, a first clamping block 24 and a second clamping block 25 mounted on the wire clamping seat 23 and clamped by the wire clamping motor 21, a guide shaft 26 that passes laterally through the wire clamping seat 23 and guides the first clamping block 24 and the second clamping block 25, a first spring 210 that is sleeved on the guide shaft 26 and opens the first clamping block 24 and the second clamping block 25, and a transmission plate 27 that is transmissively mounted between the wire clamping motor 21 and the wire clamping seat 23. The first clamping block 24 and the second clamping block 25 are respectively provided with a first through hole 28 and a second through hole 29, and the guide shaft 26 passes through the first through hole 28 and the second through hole 29, so that the first clamping block 24 and the second clamping block 25 can slide horizontally along the guide shaft 26.

[0028] One end of the transmission plate 27 is connected to the output shaft of the wire clamping motor 21, and the other end of the transmission plate 27 has a first connecting part 271 and a second connecting part 272 protruding out. The first connecting part 271 is connected to the lower end of the first clamping block 24, and the second connecting part 272 extends to the lower end of the second clamping block 25 and is connected to the lower end of the second clamping block 25 through the second transmission member 20. When the wire clamping motor 21 drives the transmission plate 27 to move, the first connecting part 271 and the second connecting part 272 respectively drive the first clamping block 24 and the second clamping block 25 to move closer to the middle to clamp the wire. Here, the wire clamp 23 also has a third through hole 235 that passes through the third receiving groove 230. Correspondingly, the second transmission member 20 has a fourth through hole 240. The second bolt 241 passes through the third through hole 235 and the fourth through hole 240 to limit the second transmission member 20 to be located in the third receiving groove 230, and the second transmission member 20 can swing about the second bolt 241 as the rotation center axis. When the transmission plate 27 moves, since the first connecting part 271 is directly connected to the first clamping block 24, the first clamping block 24 will be pushed by the first connecting part 271 to move directly towards the middle. When the second connecting part 272 moves forward, it will drive the second transmission member 20 to swing and push the second clamping block 25 to move towards the first clamping block 24, thus forming the wire clamping action.

[0029] The wire clamping base 23 is provided with a contoured groove 273 for accommodating the transmission plate 27. The wire clamping base 23 also has a third accommodating groove 230 below the first clamping block 24 for accommodating the second transmission component 20. The upper end of the first clamping block 24 is provided with a first clamping jaw 241 for clamping the wire, and the upper end of the second clamping block 25 is provided with a second clamping jaw 251 for clamping the wire. Here, both the first clamping jaw 241 and the second clamping jaw 251 have V-shaped grooves on the side that contacts the wire. During processing, this allows for a more secure clamping of the wire's tail end, effectively preventing accidental slippage of the wire during stripping and twisting by the twisting module 3, thus improving processing precision.

[0030] The twisting module 3 includes a slide rail 301 mounted on the base plate 1, a first sliding seat 32 slidably mounted on the slide rail 301, a wire clamp assembly 31 mounted on the first sliding seat 32 for clamping the wire, a stripping knife 33 mounted on the wire clamp assembly 31 for stripping the wire, a torsion drive module 34 mounted on the first sliding seat 32 for driving the wire clamp assembly 31 to rotate, a wire clamp drive assembly 35 mounted on the first sliding seat 32 for driving the wire clamp assembly 31 to clamp the wire, a push rod trigger switch 41 mounted at the front end of the wire clamp assembly 31 for detecting whether the wire is in position, and a positioning sleeve 36 mounted at the front end of the push rod trigger switch 41 for positioning the wire.

[0031] The sliding motor module 5 includes a first post-stripping motor 51 disposed on the base plate 1, a first synchronous pulley 52 disposed beside the twisting module 3, a second synchronous pulley 53 disposed on the output shaft of the first post-stripping motor 51, and a first synchronous belt 54 that can be driven between the first synchronous pulley 52 and the second synchronous pulley 53. The first sliding seat 32 is provided with a toothed plate 55 for fixed connection with the first synchronous belt 54, so that the first sliding seat 32 can slide by being driven by the first post-stripping motor 51.

[0032] When the equipment is running, the wire first needs to be manually inserted from the wire inlet 82 and passed between the first clamping block 24 and the second clamping block 25 of the wire clamping module 2. Then, the wire clamping assembly 31 of the twisting module 3 clamps the wire and drives the first sliding seat 32 to slide backward through the sliding motor module 5 to drag the wire to a preset length. Then, the twisting drive motor 34 drives the wire clamp 32 to rotate the wire. At this time, the stripping knife 33 of the twisting module 3 strips the wire, and the wire sheath falls into the waste collection box 7. The wire is twisted at the same time after stripping.

[0033] The wire clamp assembly 31 includes a rotating sleeve 311 rotatably disposed at the front end of the first sliding seat 32, a left clamping arm 312 and a right clamping arm 313 symmetrically disposed at the front end of the rotating sleeve 311 for swinging clamping of the wire, a left swing arm 314 and a right swing arm 315 symmetrically mounted on the rotating sleeve 311 for driving the left clamping arm 312 and the right clamping arm 313 to move respectively, and a reset opening spring 316 disposed between the left swing arm 314 and the right swing arm 315. The stripping knife 33 is mounted on the left clamping arm 312 and the right clamping arm 313.

[0034] The base plate 1 is also provided with a waste collection box 7 for collecting wire sheaths, and the waste collection box 7 is located between the wire clamping module 2 and the wire twisting module 3. Here, the waste generated by the twisting module 3 during the wire processing will fall into the waste collection box 7.

[0035] The base plate 1 is also covered with a protective cover module 8 to prevent foreign objects from falling into the interior. The protective cover module 8 is equipped with a control panel 81 for displaying the working status of the device. The lower end of the protective cover module 8 is also equipped with a cable inlet 82 for inserting cables. At least two control buttons 83 for controlling the device are provided on the side of the control panel 81. An emergency stop button 84 for stopping the operation of the device is also provided on the side of the control panel 81.

[0036] The wire clamp drive assembly 35 includes a sliding sleeve 351 sleeved on the rotating sleeve 311 and capable of sliding relative to it, a connecting push block 352 mounted on the sliding sleeve 351, and a first drive device 353 mounted on the first sliding seat 32 for driving the connecting push block 352 to move. A first bearing 354 is installed between the connecting push block 352 and the sliding sleeve 351. The front end of the sliding sleeve 351 forms a tapered arc surface 355 for contacting and pushing the left swing arm 314 and the right swing arm 315 apart. A second slider 356 is provided at the lower end of the connecting push block 352. Correspondingly, a second slide rail 357 is provided on the first sliding seat 32 for the connecting push block 352 to slide.

[0037] The torsion drive module 34 includes a first torsion motor 341 disposed on the first sliding seat 32 and above the clamp assembly 31, a third synchronous pulley 342 disposed on the output shaft of the first torsion motor 341, a fourth synchronous pulley 343 disposed on the rotating sleeve 311, and a second synchronous belt 344 tractably connected between the third synchronous pulley 342 and the fourth synchronous pulley 343. The first sliding seat 32 is provided with a first limit sensor 345 for stopping the movement of the sliding sleeve 351. The first limit sensor 345 is located beside the second slide rail 357. The connecting push block 352 is provided with a first sensing plate 346 for matching the first limit sensor 345.

[0038] In summary, this invention features a top rod trigger switch 41 within the twisting module 3. During operation, the wire is inserted from outside the equipment through the clamping module 2 and touches the sensing rod 412 of the top rod trigger switch 41. Once triggered, the clamping assembly 31 clamps the wire, and the twisting module 3 strips and twists it, effectively improving the processing accuracy and efficiency of the equipment. Furthermore, the operator's hands do not need to be near the twisting module 3, preventing injury and enhancing work safety. Additionally, compared to existing structures, this invention allows for the addition of a housing assembly 10 on the base plate 1, preventing the twisting module 3 and clamping module 2 from being exposed. This further enhances safety, prevents foreign objects from falling into the equipment, and effectively extends its service life.
