Description

Technical Field

[0001] The present invention relates to the field of protector wire harness processing equipment, and specifically to a protector wire cutting, twisting, tin soldering and inserting jig equipment. Background Art

[0002] The overcurrent protection components used in electronic devices mainly include ordinary fuses, thermal fuses, self - reset fuses, fuse resistors, etc. They are generally connected in series in the circuit. When abnormal phenomena such as overcurrent or overheat occur in the circuit, they will immediately cut off the circuit to play a protective role to prevent the further expansion of the fault. During the processing and manufacturing of the protection components, usually the two wire harnesses of the positive and negative poles are connected to the tin soldering station under the treatment of relevant jigs and welded to the positive and negative terminals of the protection component, such as tin soldering.

[0003] At present, during the process of wire harness access processing by the existing tin soldering and inserting jig equipment, we found the following defects: 1. Generally, it is necessary to separately cut two wire harnesses independently and move them together. The processing flow is cumbersome, time - consuming, and inefficient; 2. It is necessary to continuously adjust the orientation of the wire harness so as to implement clamping at the arrival station, which is likely to cause the wire harness to be chaotic and not neat enough, especially for longer wire harnesses. Therefore, a protector wire cutting, twisting, tin soldering and inserting jig equipment is proposed for the above problems. Summary of the Invention

The third wire groove and the semi-circular knife edge groove are on the same central axis. A side pushing cylinder is installed at the bottom end of the side clamping block located in the side clamping groove.

[0006] Preferably, the middle cutting mechanism further includes an iron core, a connecting seat, a pushing knife cylinder, an electromagnet, a connecting block and an L-shaped plate. The iron core is fixedly installed on one side of the end face of the top of the knife rod, and the iron core is magnetically attracted to the electromagnet. The electromagnet is fixedly installed on one side of the end face of the output end of the pushing knife cylinder, and a connecting block is installed on the other side of the end face of the output end of the pushing knife cylinder. The connecting block and the connecting seat located at the concave surface are connected to each other through a rotating shaft sleeved with a torsion spring. The concave surface is arranged on the other side of the end face of the top of the knife rod. The cylinder part of the pushing knife cylinder is fixedly connected to the corresponding part of the L-shaped plate.

[0007] Preferably, there are two limit strip blocks, and both of the two limit strip blocks are fixedly connected to the corresponding side walls of the U-shaped long plate through the L-shaped plates located in the middle cutting mechanism.

[0008] Preferably, a rectangular groove is opened at the end of the other side of the limit strip block, and the rectangular groove is communicated with the corresponding part of the second wire groove through a round hole. The side of the round hole is communicated with the side strip groove, and the inside of the rectangular groove is fixedly connected to the cylinder part of the wire pressing cylinder.

[0009] Preferably, a split end inserting block is installed at the middle position on the top of one side of the knife plate, and the split end inserting block externally pushes and separates the two ends of the middle cut of the wire harness.

[0010] Preferably, a wire attaching groove is opened at the top of one side of the side clamping block, and the cylinder part of the side pushing cylinder is fixedly connected to the corresponding part of the T-shaped block.

[0011] Preferably, the bottom of the T-shaped block is fixedly connected to the solder-in guide seat, and the screw hole block structure on one side of the solder-in guide seat is threadedly connected to the lead screw. One end of the lead screw is connected to an external motor.

[0012] Preferably, the top of the solder joint is inserted into the guide seat, and both sides of the height adjustment cylinder are slidably connected to the same set of third guide rails. Part of the third guide rail passes through the shuttle window on the U-shaped long plate, and the top of the shuttle window communicates with the middle part of the folding line hole.

[0013] Preferably, one side of the clamping wire-pulling component is slidably connected to the second guide rail inside the U-shaped long plate, and the other side of the clamping wire-pulling component is connected to an external servo linear motion module.

[0014] Preferably, one end of the shearing tool installation station is positioned and connected to the first guide rail outside the U-shaped long plate.

[0015] The beneficial effects of the present invention are as follows: 1. When the wire-pushing cylinder runs and extends quickly, the wire harness enters between the two limiting strip blocks with the first wire groove on the top strip block as the carrier, which is beneficial to making the two sides of this section of the wire harness parallel to each other, achieving the effect of quickly combining them together, and providing convenience for subsequent peeling, clamping, and moving the ends of this section of the wire harness.

[0016] 2. During the process of the wire harness moving from right to left between the two limiting strip blocks, a hole channel for restricting the wire harness is formed by the coincidence between the first wire groove and the second wire groove in the wire body processing mechanism, ensuring the straightness of the two sides of this section of the wire harness when entering between the two limiting strip blocks, and avoiding the bending and confusion of the wire harness.

[0017] 3. Effectively reduce the adjustment frequency of the position and orientation of the wire harness during various required processing processes before soldering, and improve the soldering processing efficiency of the wire harness.

[0018] 4. By pushing the connected side clamping block into the corresponding side clamping groove by the side-pushing cylinder, and at the same time, the wire groove on the side clamping block is tightly clamped with the corresponding part of the wire harness, it is beneficial to keep the ends of the two bare wire cores flat and immovable, and the mutual distance remains unchanged, ensuring the accuracy of the bare core end of the wire harness at the soldering point.

[0019] 5. The other end of the middle short block in the top wire mechanism contacts and presses against the cutting edge surface of the tool bar in the middle cutting mechanism, which can cut the wire harness part at the middle short block into two, realizing the function of cutting a section of wire harness into two sections, and saving the cumbersome steps of cutting the wire harness one by one.

[0020] 6. Utilize the distance between the two limiting strip blocks and cooperate with the top strip block to enter between the two limiting strip blocks, ensuring the invariability of the distance between the two wire harnesses to be processed during the processing process, and also keeping the wire harness in a straight state all the time.

[0024] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0027] Please refer to Figure 1-10 As shown, a protector wire cutting, twisting, tin soldering, and inserting jig device includes a clamping wire pulling component 1, a wire pushing mechanism 2, a height adjustment cylinder 3, a wire pushing cylinder 4, a middle cutting mechanism 5, a wire body processing mechanism 6, a wire end clamping mechanism 7, a tin soldering and inserting guide seat 8, a wire folding hole 910 on a U-shaped long plate 9, and a shear tool installation station 10. The wire harness part between the clamping wire pulling component 1 and the shear tool installation station 10 is moved into the wire body processing mechanism 6 through the wire pushing mechanism 2; A first wire groove 221 is formed in the middle of the side wall around the wire pushing strip 220 in the wire pushing mechanism 2, and an end groove 222 is formed on one end face of the wire pushing strip 220. A rectangular hole 223 on the inner wall of the end groove 222 is elastically connected to one end of a middle short block 210 through a spring. The other end of the middle short block 210 is in contact with the cutting edge surface of a tool bar 510 in the middle cutting mechanism 5. The wire pushing strip 220 is moved to the front of the wire folding hole 910 through the height adjustment cylinder 3, and the output ends of the height adjustment cylinder 3 and the wire pushing cylinder 4 are connected to each other; The specific solution here: Combine Figure 2 and Figure 3As shown, the telescopic movement of the height adjustment cylinder 3 pushes the connected top line block 220 to the front of the folding line hole 910. At the same time, ensure that the middle horizontal plane of the first wire groove 221 on the top line block 220 coincides with the middle horizontal plane of the folding line hole 910, and the first wire groove 221 contacts the wire harness part at the folding line hole 910 through the connection and pushing of the wire pushing cylinder 4; At the moment when the clamping wire pulling component 1 and the shearing tool installation station 10 complete the synchronous cutting of this section of the wire harness, the wire pushing cylinder 4 runs and quickly extends to make this section of the wire harness enter between the two limit strip blocks 640 with the first wire groove 221 on the top line block 220 as the carrier, which is beneficial to making the two sides of this section of the wire harness in a parallel state, achieving the effect of quickly combining them together, and providing convenience for subsequent peeling, clamping, and moving of the end of this section of the wire harness.

[0028] A hole channel for restraining the wire harness is formed by the coincidence between the first wire groove 221 and the second wire groove 644 in the wire body processing mechanism 6. The second wire groove 644 is opened at the middle position on one side of the limit strip block 640, and a side strip groove 642 is opened at one end inside the second wire groove 644. One end of the connecting rod 620 in the side strip groove 642 is installed with a half-ring knife 610, and the other end of the connecting rod 620 is fixedly connected to the output end of the wire pressing cylinder 630. The semi-circular blade groove 711 is soldered into the guide seat 8 and moves to form a complete annular peeling knife structure with the same-side half-ring knife 610; The specific solution here: Combine Figure 6 、 Figure 7 and Figure 10 As shown, during the process of this section of the wire harness moving from the right end to the left between the two limit strip blocks 640, a hole channel for restraining the wire harness is formed by the coincidence between the first wire groove 221 and the second wire groove 644 in the wire body processing mechanism 6, ensuring the straightness of the two sides of this section of the wire harness when entering between the two limit strip blocks 640, avoiding the bending and chaos of the wire harness, and the middle cutting mechanism 5 cuts this section of the wire harness part at the end face of the middle short block 210 into two; When the two ends formed by cutting the middle of the wire harness penetrate into the annular peeling knife structure formed by the half-ring knife 610 and the semi-circular blade groove 711, the wire pressing cylinder 630 runs, and its output end face passes through the round hole 643 to press and fix the wire harness part at the corresponding position of the first wire groove 221. At the same time, the half-ring knife 610 connected to the output end of the wire pressing cylinder 630 through the connecting rod 620 approaches the semi-circular blade groove 711 to cut through the insulating skin at the end of the wire harness. At the same time, the two side clamping blocks 750 in the wire end clamping mechanism 7 respectively clamp and fix the insulating skin parts at the corresponding ends of the wire harness to be peeled; At this time, the solder joint feeding guide seat 8 that can be traction - moved drives the wire - end clamping mechanism 7 connected thereto to move leftward along the third guide rail 13, so that the part where the insulating skin is penetrated and cut is separated from the wire core of the wire harness, completing the wire harness stripping; For the second time, the solder joint feeding guide seat 8 that can be traction - moved drives the wire - end clamping mechanism 7 connected thereto to move rightward along the third guide rail 13, so that the two side clamping blocks 750 respectively clamp and fix the two exposed wire core ends. At the same time, the pressing cylinder 630 and the half - ring knife 610 both reset, releasing the fixation of the part of the wire harness located between the two limiting strip blocks 640; For the third time, the solder joint feeding guide seat 8 that can be traction - moved drives the wire - end clamping mechanism 7 connected thereto to move leftward along the third guide rail 13, so that the two combined wire harness segments separated from the two limiting strip blocks 640 are sent to the soldering station, and the bare core ends of the two wire harness segments are placed at the welding points; In summary, the frequency of position and orientation adjustment during various required processing procedures before wire harness soldering is effectively reduced, improving the wire harness soldering processing efficiency.

[0029] The knife plate 710 in the wire - end clamping mechanism 7 is fixedly installed on one side wall of the T - shaped block 730, and semi - circular knife blade grooves 711 are opened at both top corners of the knife plate 710. Third wire grooves 732 and side clamping grooves 731 are respectively opened at the two top ends and the middle position on both sides of the T - shaped block 730. The third wire groove 732 and the semi - circular knife blade groove 711 are on the same central axis. A side - pushing cylinder 740 is installed at the bottom end of the side clamping block 750 located in the side clamping groove 731; The specific solution here: In combination with Figure 8 and Figure 9 As shown, when the corresponding end of the wire harness enters the corresponding third wire groove 732, the side - pushing cylinder 740 pushes the connected side clamping block 750 into the corresponding side clamping groove 731. At the same time, the wire - attaching groove 751 on the side clamping block 750 is tightly clamped with the corresponding part of the wire harness, which is beneficial to keeping the two exposed wire core ends in a flat and immovable state, and the mutual distance remains unchanged, ensuring the accuracy of placing the bare core end of the wire harness at the soldering point.

[0030] The middle cutting mechanism 5 further includes an iron core 511, a connecting seat 513, a push knife cylinder 520, an electromagnet 521, a connecting block 522 and an L-shaped plate 530. The iron core 511 is fixedly installed on one side of the top end face of the knife rod 510, and the iron core 511 is magnetically attracted and connected to the electromagnet 521. The electromagnet 521 is fixedly installed on one side of the output end face of the push knife cylinder 520, and a connecting block 522 is installed on the other side of the output end face of the push knife cylinder 520. The connecting block 522 and the connecting seat 513 located at the concave surface 512 are connected to each other through a rotating shaft sleeved with a torsion spring. The concave surface 512 is arranged on the other side of the top end face of the knife rod 510. The cylinder body part of the push knife cylinder 520 is fixedly connected to the corresponding part of the L-shaped plate 530; The specific implementation plan here: Refer to Figure 4 and Figure 5 As shown, when the push knife cylinder 520 operates, it pushes the knife rod 510 magnetically fixed to the iron core 511 by the electromagnet 521 to move downward into the middle position between the two limit strip blocks 640. Under the action of the push wire cylinder 4 pushing the top wire mechanism 2 connected by the height adjustment cylinder 3 to move leftward, the other end of the middle short block 210 in the top wire mechanism 2 comes into contact with and presses against the cutting edge surface of the knife rod 510 in the middle cutting mechanism 5, enabling the wire harness part at the middle short block 210 to be cut into two, realizing the function of cutting a wire harness into two segments, and saving the cumbersome steps of cutting each wire in the wire harness one by one; After the wire harness is cut, the electromagnet 521 is instantly powered off and loses magnetism, releasing the fixation of the knife rod 510 connected to the iron core 511. The knife rod 510 rotates upward and leftward under the push of the middle short block 210 until the knife rod 510 disengages from the other end of the top wire strip 220. Combining the connection between the connecting block 522 and the connecting seat 513 located at the concave surface 512 through a rotating shaft sleeved with a torsion spring, the knife rod 510 quickly resets. The electromagnet 521 is powered on to magnetically fix the iron core 511 together, and the push knife cylinder 520 contracts to pull the knife rod 510 back to the initial height position to prevent hindering the return movement of the top wire mechanism 2.

[0031] There are two limit strip blocks 640, and both of the two limit strip blocks 640 are fixedly connected to the corresponding side walls of the U-shaped long plate 9 through the L-shaped plate 530 in the middle cutting mechanism 5. By using the distance between the two limit strip blocks 640 and cooperating with the top wire strip 220 entering between the two limit strip blocks 640, the invariability of the distance between the two wire harnesses to be processed during the process is ensured, and the wire harness can always be in a straight state.

[0032] On the other end of the limiting bar block 640, a rectangular groove 641 is provided, and the rectangular groove 641 communicates with the corresponding part of the second wire groove 644 through a round hole 643. The lateral side inside the round hole 643 communicates with the side bar groove 642, and the inside of the rectangular groove 641 is fixedly connected to the cylinder part of the wire pressing cylinder 630.

[0033] At the middle position of the top of one side of the knife plate 710, a split end inserting block 720 is installed. The split end inserting block 720 pushes the two ends of the cut wire harness in the middle outwards to prevent the two ends of the newly formed wire harness at the cut part from not separating, so that the newly formed wire harness ends are located in the corresponding first wire groove 221 or the second wire groove 644.

[0034] On the top of one side of the side clamping block 750, a wire attaching groove 751 is provided. The cylinder part of the side pushing cylinder 740 is fixedly connected to the corresponding part of the T-shaped block 730.

[0035] The bottom of the T-shaped block 730 is fixedly connected to the solder joint feeding seat 8, and the screw hole block structure on one side of the solder joint feeding seat 8 is threadedly connected to the lead screw 14. One end of the lead screw 14 is connected to an external motor. By driving the connected lead screw 14 to rotate through the external motor, the solder joint feeding seat 8 connected to the other end of the lead screw 14 moves left or right along the third guide rail 13.

[0036] The top of the solder joint feeding seat 8 and both sides of the height adjusting cylinder 3 are slidably connected to the same group of third guide rails 13, and a part of the third guide rail 13 passes through the shuttle window 920 on the U-shaped long plate 9. The top of the shuttle window 920 communicates with the middle part of the folding wire hole 910.

[0037] One side of the clamping wire pulling component 1 is slidably connected to the second guide rail 12 inside the U-shaped long plate 9, and the other side of the clamping wire pulling component 1 is connected to an external servo linear motion module. One end of the shear tool installation station 10 is positioned and connected to the first guide rail 11 outside the U-shaped long plate 9, so as to meet the control operation requirements for initially cutting the wire harness.
