[0028] Embodiment 1: a lead detection device, as shown in the figure, comprising a workbench 1, a detection mechanism, a folding mechanism, a cutting mechanism and a tape winding mechanism, the detection mechanism, the folding mechanism and the cutting mechanism are sequentially arranged on the workbench 1 from right to left, and the tape winding mechanism is arranged on the workbench 1 and located in front of the folding mechanism, the detection mechanism is used for detecting the exposed copper of the lead, the folding mechanism is used for bending the lead, the tape winding mechanism is used for conveying the bent lead to the direction of the cutting mechanism, and the cutting mechanism is used for cutting the lead with exposed copper. Figures 1-10 The worker rotates the spool wound with the lead in advance on the workbench 1, and then intermittently conveys the single lead to the direction of the folding mechanism at equal intervals. In the conveying process, the detection mechanism can detect the exposed copper of the lead, and when the exposed copper of the lead is detected, the state of this section of lead is marked as NG in the program. When the lead is conveyed to the position of the folding mechanism, the folding mechanism cuts the lead, and then bends the cut section of the lead into a U shape. The tape winding mechanism encapsulates the bent lead into the carrier tape and conveys it to the direction of the cutting mechanism. When the section of lead marked as NG is conveyed to the position of the cutting mechanism, the cutting mechanism cuts the lead, and the unmarked lead is not cut.

[0029] Embodiment 2: based on embodiment 1, as shown in the figures,

[0030] Figure 1 Figure 3 Figure 5 the detection mechanism comprises a detection seat 101 and an exposed copper detector 102, the workbench 1 is fixedly connected with the detection seat 101, the detection seat 101 is provided with a threading hole 103 for the lead to pass through, and the detection seat 101 is fixedly connected with the exposed copper detector 102. The exposed copper detector 102 is an instrument capable of detecting exposed copper in the prior art, and the exposed copper detector 102 is located on the side of the threading hole 103 entering the lead.

[0031] The lead in the conveying process to the folding mechanism passes through the exposed copper detector 102 and the threading hole 103, and the exposed copper detector 102 can detect the lead with exposed copper.

[0032] As shown in the figures, Figure 1 Figure 3 Figure 4 Figure 6 Figure 7 ​​​​​​​As shown, the folding mechanism includes a folding guide rail 2, a folding slider 201, a first support 202, a folding seat 203, a hook block 204, a line stop 205, a line stop guide rod 206, a line stop bracket 207, a first spring 208, a line stop plate 209, a lifting assembly, and a cutting assembly. The folding guide rail 2 is fixedly connected to the worktable 1. The folding slider 201 is slidably connected to the folding guide rail 2 in the horizontal direction. A first support 202 is fixedly connected to the top of the folding slider 201. A folding seat 203 is fixedly connected to the first support 202. Two hook blocks 204 are symmetrically fixed to the top of the folding seat 203, with a gap between the two hook blocks 204. Figure 7 As can be seen, a channel is formed between the lower side of the hook block 204 and the bending seat 203. This channel is used to accommodate the lead wire for bending. A wire stop seat 205 is fixedly connected to the workbench 1. Two wire stop guide rods 206 are symmetrically fixed to the wire stop seat 205. A wire stop bracket 207 is slidably connected to the wire stop guide rod 206 in the vertical direction. A first spring 208 is sleeved on the wire stop guide rod 206. When the wire stop bracket 207 slides upward, it will compress the first spring 208. A wire stop plate 209 is fixedly connected to the wire stop bracket 207, and the wire is blocked. The plate 209 is located between two hook blocks 204. During the process of the hook blocks 204 dragging the lead wire toward the guide plate 209, the guide plate 209 bends the lead wire into a U-shape by blocking the middle of the lead wire. A lifting component is connected to the first support 202. The lifting component is used to drive the guide plate 209 upward to disengage from the lead wire, so that the hook blocks 204 can transport the bent lead wire to the tape feeding mechanism. A wire cutting component is installed on the detection seat 101. The wire cutting component is used to cut the lead wire at equal intervals so that the hook blocks 204 can be dragged.

[0033] like Figure 6 As shown, the lifting assembly includes an upper top block 3 and a rotating top plate 301, from... Figure 7 As can be seen, a blind hole is provided on the first support 202, and the rotating top plate 301 is rotatably connected in the blind hole. A torsion spring is provided between the rotating top plate 301 and the first support 202, so that the rotating top plate 301 can be rotated and reset through the torsion spring. The rotating top plate 301 can only rotate within a range of 90 degrees. Figure 7 The rotating top plate 301 in the vertical position can rotate 90 degrees counterclockwise. The torsion spring is used to drive the rotating top plate 301 to rotate 90 degrees clockwise to reset. The upper top block 3 is fixed on the wire stop plate 209. The upper top block 3 is a right trapezoid. The rotating top plate 301 is used to press the upper top block 3 to drive the wire stop plate 209 upward to disengage from the lead wire.

[0034] like Figures 3-5As shown, the cutting assembly includes a cutting guide frame 302 and a cutting knife 303. The cutting guide frame 302 is fixed to the detection seat 101 away from the copper exposure detector 102. The cutting knife 303 is slidably connected to the cutting guide frame 302. The cutting knife 303 is used to cut the lead wire that is drawn out of the threading hole 103.

[0035] The lead wire is intermittently sent out from the threading hole 103 of the detection seat 101. When the lead wire is not sent to the front side of the folding seat 203, the folding slider 201 is first controlled to slide forward. Then the lead wire in the threading hole 103 is sent a fixed distance to the left. Then the folding slider 201 is controlled to slide back to reset, and the cutting knife 303 is controlled to slide back. The cutting knife 303 first cuts the lead wire that is drawn out. The lead wire falls on the folding seat 203. During the process of the folding slider 201 sliding back to reset, the lead wire is dragged by the hooking block 204 to the direction of the blocking plate 209. The hooking block 204 and the blocking plate 209 cooperate to bend the lead wire into a U shape. The two sides of the lead wire are located in the channel formed between the hooking block 204 and the folding seat 203. When the folding slider 201 slides forward, the upper top block 3 lifts the rotating top plate 301. The rotating top plate 301 drives the blocking plate 209 to move upward. The first spring 208 is compressed, so that the blocking plate 209 and the bent lead wire are separated from each other. Thus, the hooking block 204 and the folding seat 203 can drive the bent lead wire to move to the front side, so as to send the bent lead wire to the forward side of the braiding mechanism. Then the rotating top plate 301 is separated from the upper top block 3. The first spring 208 drives the blocking support 207 and the blocking plate 209 to reset downward. The blocking plate 209 can cooperate with the hooking block 204 again to bend the lead wire. When the folding slider 201 slides back to reset, the upper top block 3 drives the rotating top plate 301 to rotate into the blind hole of the first support 202. When the folding slider 201 resets, the rotating top plate 301 is separated from the upper top block 3. The rotating top plate 301 resets under the action of the torsional spring.

[0036] As shown in Figure 1 , Figure 3 and Figure 8 , the cutting mechanism includes a cutting frame 4, a gas cylinder 401, a cutting knife 402 and a protective frame 403. The cutting frame 4 is fixed to the workbench 1. The gas cylinder 401 is fixed to the cutting frame 4. The cutting knife 402 is fixed to the extension shaft of the gas cylinder 401. The cutting knife 402 is used to cut the lead wire that exposes the copper on the braiding mechanism. Two protective frames 403 are symmetrically fixed to the cutting frame 4.

[0037] When the marked lead wire is sent to the lower side of the cutting knife 402, the gas cylinder 401 extends downward, so that the cutting knife 402 cuts the lead wire.

When the wire feeding slider 601 slides towards the fixed clamping block 609, the wire clamping guide 605 first slides towards the wire feeding guide 6, so that the outer clamping block 604 cooperates with the inner clamping block 603 to clamp the wire, and the pneumatic clamping block 610 is away from the fixed clamping block 609, thereby feeding the wire towards the copper exposure detector 102. When the wire feeding slider 601 slides away from the fixed clamping block 609, the wire clamping guide 605 first slides away from the wire feeding guide 6 under the pushing of the second spring 608, so that the outer clamping block 604 moves away from the inner clamping block 603 to release the clamping of the wire, and the pneumatic clamping block 610 is controlled to move towards the fixed clamping block 609 to clamp the wire, thereby preventing the wire from retracting. By repeating the above steps, the wire can be intermittently fed to the left, and the length of each feeding is equal.

When the wire feeding slider 601 slides towards the fixed clamping block 609, the wire clamping guide 605 first slides towards the wire feeding guide 6, so that the outer clamping block 604 cooperates with the inner clamping block 603 to clamp the wire, and the pneumatic clamping block 610 is away from the fixed clamping block 609, thereby feeding the wire towards the copper exposure detector 102. When the wire feeding slider 601 slides away from the fixed clamping block 609, the wire clamping guide 605 first slides away from the wire feeding guide 6 under the pushing of the second spring 608, so that the outer clamping block 604 moves away from the inner clamping block 603 to release the clamping of the wire, and the pneumatic clamping block 610 is controlled to move towards the fixed clamping block 609 to clamp the wire, thereby preventing the wire from retracting.

[0044] As Figure 1, Figure 3 and Figure 4 As shown, it also includes a driven mechanism for driving the zigzag slider 201 and the cutting blade 303. The driven mechanism includes a driven seat 8, a driven shaft 801, an upper pulley assembly 802, a bevel gear assembly 803, a rotating shaft 804, a lower pulley assembly 805, a driven cam 806, a rocker arm 807, a pull rod 808, and a driven torsion spring 809. Two driven shafts 801 are rotatably connected to the lower side of the worktable 1 through multiple driven seats 8. The two driven shafts 801 are located at the same height but perpendicular to each other, and the drive shaft 701 is driven by one of the driven shafts 801 through the upper pulley assembly 802. The two driven shafts 801 are driven by the bevel gear assembly 803. A rotating shaft 804 is rotatably connected to the lower side of the worktable 1. Shaft 804 is connected to another driven shaft 801 via a lower pulley group 805. Two driven cams 806 are fixed on the rotating shaft 804, but the two driven cams 806 are set at different angles. Two rocker arms 807 are rotatably connected to the worktable 1. A driven torsion spring 809 is sleeved on the rotating shaft of the rocker arm 807. One end of the driven torsion spring 809 is fixed to the bracket on the lower side of the worktable 1, and the other end of the driven torsion spring 809 is fixed to the rocker arm 807. One end of a pull rod 808 is rotatably connected to the upper side of each rocker arm 807. The other end of one pull rod 808 is rotatably connected to the wire cutter 303, and the other end of the pull rod 808 is rotatably connected to the first support 202.

[0045] When the drive shaft 701 rotates, it drives the rotating shaft 804 to rotate synchronously via the upper pulley assembly 802, driven shaft 801, bevel gear assembly 803, and lower pulley assembly 805. During the rotation of the transmission shaft 707, one of the driven cams 806 first presses against an adjacent rocker arm 807. This rocker arm 807 then drives the wire cutter 303 to slide backward via the pull rod 808 to cut the lead wire. Then, another driven cam 806 presses against another rocker arm 807, which then drives the wire cutter 303 to slide backward via the pull rod 808. The folding slider 201 slides backward, thereby bending the lead wire through the hook block 204 and the wire stop plate 209. When the rocker arm 807 is squeezed and rotated, it will store the power of the connected driven torsion spring 809. When the driven cam 806 disengages from the corresponding rocker arm 807, the driven torsion spring 809 will drive the rocker arm 807 to rotate and reset. The rocker arm 807 will first push the wire cutter 303 forward to reset via the pull rod 808, and then push the folding slider 201 forward to slide, so as to cut and bend the lead wire again.
