[0025] Depend on Figures 1 to 5As shown, this utility model includes a bracket 1 installed at the discharge end of the cable forming machine, a wire feeding mechanism installed on one side of the bracket 1, a length measuring mechanism installed on the other side of the bracket 1, and a wire cutting mechanism installed on the bracket 1 and located between the wire feeding mechanism and the length measuring mechanism.

[0026] Specifically, the length measuring mechanism includes a fixed plate 10 mounted on a support 1 and a support plate 11 mounted on the support 1 and adjacent to the fixed plate 10. A length measuring wheel 12 connected to a controller 6 is mounted on the fixed plate 10. A linear motor 13 is mounted on the support plate 11.

[0027] The wire cutting mechanism also includes a through hole 24 on the fixed block 2 for the cable to pass through.

A power motor 23 connected to the controller 6 is fixed on the connecting plate 22. The saw disc 20 is connected to the output end of the power motor 23. A cutting groove 241 communicating with the through hole 24 is provided on the fixed block 2 at the position corresponding to the saw disc 20.

[0028] The wire feeding mechanism includes a support frame 3 connected to the bracket 1, a take-up wheel 30 rotatably mounted on the support frame 3, and a clamp 31 vertically mounted on the wheel surface of the take-up wheel 30.

[0029] Two support blocks 32 are symmetrically arranged on the support frame 3. A winding wheel 30 is provided between the two support blocks 32. A rotating shaft 301 passes through the middle of the winding wheel 30. A slot 302 is provided on the end face of the protruding end of the rotating shaft 301. Each support block 32 is provided with a clearance groove 321. The two ends of the rotating shaft 301 extend into the clearance grooves 321 at the corresponding ends. A servo motor 33 connected to the controller 6 is provided on the support block 32 adjacent to the slot 302. The output end of the servo motor 33 extends into the clearance groove 321 at the corresponding end and is connected to the rotating shaft 301. Specifically, A transmission rod 34 extending into a clearance groove 321 is connected to the output end of the servo motor 33. A straight section 341 is provided at the extension end of the transmission rod 34, and a connecting through hole 342 is provided on the straight section 341. A connecting hole 303 is provided on the groove wall of the slot 302 at the position corresponding to the connecting through hole 342. The straight section 341 extends into the slot 302, and a locking bolt passes through the connecting hole 303 and the connecting through hole 342. A nut is screwed onto the protruding end of the locking bolt, and the nut abuts against the outer wall of the rotating shaft 301, so that the winding wheel 30 is fixedly connected to the output end of the servo motor 33.

[0030] The support assembly includes a support plate 35 extending horizontally from each of the support blocks 32. The two support plates 35 are arranged facing each other and symmetrically. Each support plate 35 has a vertical plate at its extended end. Each vertical plate has a groove 351 at its upper end. The groove wall of the groove 351 is fitted to the outer wall of the rotating shaft 301.

[0031] In addition, a fixing frame 16 is provided on the bracket 1, a universal joint 17 is provided on the fixing frame 16, a sleeve is connected to the movable end of the universal joint 17, and an air blowing pipe 18 is fixedly installed inside the sleeve.

[0032] The working principle of this utility model is as follows:

[0033] like Figures 1 to 5As shown, the end of the cable prepared by the cable-forming machine (not shown) is placed on the upper wheel surface of the length-counting wheel 12 and marked as 0 on the controller 6. The controller starts the linear motor 13, which drives the pressure plate 14 to move down through the connecting rod 131, so that the inner side wall of the arc-shaped pressure plate 14 fits against the outer side wall of the cable. The linear motor 13 is then turned off, and the cable continues to be pulled out. The friction between the cable and the length-counting wheel 12 drives the length-counting wheel 12 to rotate synchronously. At this time, the controller 6 starts to measure the length according to the rotation of the length-counting wheel 12, pulls the cable to move and moves it out through the through hole 24 on the fixing block 2. The moved cable moves to the position of the winding wheel 30, and then the end of the cable is fitted onto the clamp 31. Then, the controller 6 starts the servo motor 33 to drive the winding wheel 30 to rotate, which also pulls the cable to move and realizes the winding operation on the winding wheel 30. In order to ensure the stability of pulling the cable, the number of clamps 31 should be set according to the specific use conditions, which will not be elaborated here.

[0034] When the length of the cable reaches the winding length requirement of the winding wheel 30, the count of the controller 6 is reset to zero and the controller 6 temporarily shuts down the servo motor 33. Then the controller 6 turns on the engraving machine 15, which engraves a mark on the outer wall of the cable through the clearance hole 141 on the pressure cover 14. Subsequently, the controller 6 turns on the servo motor 33 again, driving the cable to continue moving and moving the mark to the position of the cutting groove 241, and then turns off the servo motor 33.

[0035] Next, the controller 6 starts the stepper motor 21, which drives the connecting plate 22 to rotate. At the same time, the saw disc 20 also rotates in the vertical direction in sync with the connecting plate 22. When one side of the saw disc 20 enters the cutting groove 241, the controller 6 starts the power motor 23 to make the saw disc 20 rotate. Combined with the continued rotation of the connecting plate 22, the cable is cut at the marked position. At this time, the power motor 33 is turned off and the stepper motor 21 is started to rotate, which drives the saw disc 20 to leave the cutting groove 241. The servo motor 33 is then started to bring out the cut cable.

[0036] Finally, loosen the nut and remove the locking bolt to disconnect the transmission rod 34 from the rotating shaft 301. Since the groove wall of the groove 351 is fitted to the outer wall of the rotating shaft 301, the winding wheel 30 remains stable when the connection is disconnected, allowing the upper end of the groove 321 to open. At this time, the winding wheel 30 can be moved away as a whole.

[0037] By observing and comparing the state of the engraving marks at the cutting position, that is, the relative position between the cutting position and the mark, one can intuitively understand the state of the cutting. If it exceeds the tolerance range, adjustments should be made in time.

[0038] Subsequently, as Figure 2 and Figure 3As shown, an empty take-up reel 30 is placed on top, with the straight section 341 extending into the slot 302. A locking bolt passes through the connecting hole 303 and the connecting through hole 342. A nut is screwed onto the protruding end of the locking bolt, and the nut abuts against the outer wall of the rotating shaft 301, so that the take-up reel 30 is fixedly connected to the output end of the servo motor 33. Then, according to the aforementioned relevant content, the cable is pulled out, and the cut end of the cable is fixed on the clamp 31. The controller 6 starts the servo motor 33. After the length is measured, the cutting operation is performed again. This process is repeated to achieve segmented take-up of the cable.

[0039] During production operations, in order to ensure the accuracy of the measured length, the air pump (not indicated) should be turned on in a timely manner to discharge air through the air blowing pipe 18. Since the air blowing pipe 18 is connected to the movable end of the sleeve and the universal joint 17, the air blowing pipe 18 can be rotated to achieve dust removal at the positions of the length measuring wheel 12, the pressure cap 14 and the through hole 24. Similarly, in order to ensure the smooth rotation of the winding wheel 30, lubricating fluid should be added to the groove 351 in a timely manner.

[0040] It should be noted that since the installation positions of the length measuring wheel 12 and the cutting groove 241 are fixed, the distance between the upper wheel surface of the length measuring wheel 12 and the cutting groove 241 is constant. After the length is measured, the distance to move to the cutting position can be preset on the controller 6 so as to achieve the continuity and automation of intermediate processing actions.

[0041] In addition, the use of the equipment is also explained. Since the output end of the linear motor 13 can drive the pressure plate 14 and the engraving machine 15 to move synchronously in the vertical direction, and considering the usage environment, the engraving machine 15 should be a miniature engraving machine. The engraving machine 15 only needs to place the components of the working part on the pressure plate 14. At the same time, the clearance hole 141 is provided at the engraving output position, which also simplifies the overall installation structure of the tooling.

[0042] In this embodiment, the controller 6 is a PLC controller, which is only for direct use and does not require any changes to the operating program. After the cable length is measured, the zeroing on the controller 6 can be done manually. While ensuring convenient operation, it does not involve any changes to the program of the controller 6. Therefore, the connection of the controller 6 will not be described in detail here.
