Description

Technical Field

[0001] This invention relates to the field of wire harness processing equipment technology, and in particular to a multi-wire merging crimping machine for sleeves and its usage method. Background Technology

[0002] Currently, in the field of wire harness processing equipment, it is necessary to complete the process of pressing the terminals of the main wire (single wire harness) and the auxiliary wire (multiple combined wire harnesses, which are formed by twisting the bare copper wire ends of multiple wire harnesses together to form a combined wire) together in opposite directions, and then inserting heat shrink tubing at the joint and positioning it to shrink it.

[0003] Several related sleeve termination and splicing devices have been disclosed in the prior art. For example, patent application CN214849495U proposes a multi-wire sleeve termination and splicing mechanism, and patent application CN113328317A proposes a fully automatic wire cutting, stripping, termination, sleeve, and multi-wire splicing machine. In the technical solutions of the above two devices, the sleeve action is performed when merging and splicing multiple wires by pushing the heat shrink tubing from the direction of multiple wire bundles to the direction of a single wire bundle. That is, after the single wire bundle is connected to the bare copper wire end of the multiple merged wire bundles with the heat shrink tubing, the heat shrink tubing is pulled towards the single wire bundle by the wire pulling mechanism until the heat shrink tubing is covered and sleeved at the termination connection point. The heat shrink tubing is then heated and shrunk and fixed by an electric soldering iron.

[0004] However, since the diameter of the multiple combined wire harnesses is relatively large, and the multiple wire harnesses will be twisted to a certain extent when they are combined, the combined wire harness will cause a certain degree of obstruction when the heat shrink tubing is pushed from the combined wire harness to the single wire harness for sheathing. This will increase the failure rate during the sheathing operation. In other words, the above sheathing method has strict requirements on the twisting degree of the wire and the hole diameter tolerance of the heat shrink tubing. Summary of the Invention

[0022] The present invention also provides the following technical solution: a method for using a multi-wire merging crimping machine for sleeves, comprising the following steps:

[0023] Step 1: Control the operation of the tube feeding and cutting mechanism. The specific process is as follows:

[0024] First, control the tube feeding motor to work. Through the rotation of the drive gear, the driven gear, the conveying gear and the conveying cylinder will be driven to rotate synchronously. Through the rotation of the left and right conveying cylinders, the heat shrink tubing will be conveyed forward under the guidance of guide tube one and guide tube two to the pneumatic cutter. When it has been conveyed forward to a certain length, control the pneumatic cutter to work. The pneumatic cutter will automatically cut the heat shrink tubing into a section.

[0025] Step Two: Control the operation of the first conveying mechanism. The specific process is as follows:

[0026] First, control the pneumatic gripper to simultaneously grab and hold the section of heat shrink tubing cut in step one. Then, control the transport motor to drive the transport arm and pneumatic gripper to move along the slide rail in the left and right directions through the transmission of the synchronous pulley and synchronous toothed belt until the pneumatic gripper transports the tubing to the front station of the wire feeding sleeve mechanism.

[0027] Step 3: Control the operation of the wire feeding sleeve mechanism. The specific process is as follows:

[0028] First, the wire feeding assembly is controlled to operate, specifically by controlling the wire feeding motor. This drives the rotation of wire feeding gear one, which, in conjunction with the transmission belt, synchronously drives wire feeding gears two, three, four, and five to rotate. Wire feeding gear two then synchronously drives the lower conveyor wheel, and wire feeding gear five synchronously drives the upper conveyor wheel. The rotation of the upper and lower conveyor wheels drives the main wire, i.e., the single wire harness, forward under the guidance of the wire feeding guide tube and guide block to the conduit at the sleeve assembly. At this time, the linear module is simultaneously controlled to operate, i.e., the external driver is controlled to operate, driving the transmission gear two to rotate. This synchronously drives the transmission shaft and transmission gear one to rotate. With the cooperation of transmission gear one and the moving frame with a rack and pinion, the moving frame, wire feeding assembly, and sleeve assembly are driven to move forward on the slide groove of the fixed platform until the conduit is moved forward and inserted into the heat shrink tubing held and fixed by the pneumatic jaws in step two. When the process of inserting the conduit into the heat shrink tubing is completed, the first transport mechanism is synchronously controlled to return to its original position, waiting for the clamping of the next section of heat shrink tubing.

[0029] Then, the wire feeding assembly continues to operate, that is, by using the rotation of the upper and lower conveyor wheels, the single wire harness is driven forward to be fed between the rear fixed V-shaped cutter and the moving V-shaped cutter in the stripping mechanism, and then continues to be fed forward to a certain distance, which does not exceed the distance between the front and rear fixed V-shaped cutters or the moving V-shaped cutters.

[0030] Step 4: Control the operation of the peeling mechanism. The specific process is as follows:

[0031] First, control the external driver to work, drive the power gear and transmission gear to rotate. With the cooperation of the transmission gear and the moving plate with meshing teeth, drive the moving plate and the moving V-shaped cutter on it to move upward until the single wire harness is stripped by the fixed V-shaped cutter and the moving V-shaped cutter on the rear.

[0032] During the stripping action, the wire feeding assembly is controlled to work simultaneously, that is, to drive a single wire harness to retract a certain distance so that the front end of the single wire harness is completely stripped of its outer sheath.

[0033] After the above stripping process is completed, continue to control the wire feeding assembly to continue to feed the single wire harness forward to the crimping station of the terminal crimping mechanism.

[0034] Step 5: Control the second handling mechanism to transport the auxiliary wires (multiple combined wire bundles) transferred by the robot arm in the previous process to the pneumatic gripper of the wire pulling mechanism. The working process of the second handling mechanism is the same as that of the first handling mechanism. The multiple combined wire bundles are clamped and fixed by the pneumatic gripper.

[0035] Step Six: First, control the terminal crimping mechanism to complete the process of crimping the bare core ends of multiple combined wire harnesses and single wire harnesses;

[0036] When performing the above-mentioned terminal crimping action, it also includes:

[0037] The synchronous control sleeve assembly moves the pressing cylinder, which drives the moving block and the guide tube on it to move down, that is, drives the single wire harness in the guide tube to move down until it moves down to the crimping station;

[0038] Synchronous control of the pneumatically driven pressing block movement enables it to complete the pressing process of the pneumatic gripper jaws through downward movement, that is, to drive the multiple combined wire harnesses clamped and fixed on the pneumatic gripper jaws to move down until they move down to the crimping station.

[0039] When the above terminal crimping process is completed, control the downward pressing cylinder to move it, causing it to drive the single wire harness to return to its upward position; control the pneumatic pressing block to move it, causing it to return to its upward position. At this time, the pneumatic gripper uses the elastic force of the spring rod to return to its position, causing the multiple combined wire harnesses to return to their upward position.

[0040] Step 7: Control the forward-pushing cylinder in the sleeve assembly to move forward synchronously, driving the forward push rod and the forward-pushing slide sleeve to move forward, pushing the heat shrink tubing sleeved on the guide tube forward until the front end of the heat shrink tubing is pushed onto the multiple combined wire harnesses, and at this time the heat shrink tubing has covered the connection point of the mating terminal; then control the air-driven soldering iron to move down, and use the heat of the soldering iron to shrink and fix the heat shrink tubing at the connection point of the mating terminal;

[0041] Step 8: Control the operation of the wire feeding assembly and the wire pulling mechanism. The specific process is as follows:

[0042] When the wire feeding assembly is working, it drives the single wire harness to continue to be fed forward;

[0043] Simultaneously, the wire pulling mechanism is controlled to operate, i.e., the wire pulling motor is controlled to operate, driving the rotating gear to rotate. With the cooperation of the rotating gear and the moving arm with meshing teeth, the moving arm and its pneumatic grippers move forward along the slide, driving multiple combined wire harnesses forward. That is, through the cooperation of the above-mentioned wire feeding assembly and wire pulling mechanism, the wire harnesses after being connected and merged with the sleeve are conveyed forward until the length of a single wire harness conveyed through the conduit meets a certain requirement. At this time, the stripping mechanism is controlled to operate, using the fixed V-shaped cutter and the moving V-shaped cutter on the rear side to complete the cutting action of the rear end of the single wire harness; using the fixed V-shaped cutter and the moving V-shaped cutter on the front side to complete the stripping action of the rear end of the cut single wire harness.

[0044] The above-mentioned stripping action on the rear end of a single wire harness also includes: controlling the pneumatic pliers in the wire pulling mechanism to continue moving forward a certain distance so that the rear end of the single wire harness is completely stripped of its outer sheath.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] 1. The present invention features a novel and unique sleeve structure design when performing the sleeve operation on the heat shrink tubing. The sleeve process is as follows: First, the linear module operates to drive the guide tube to be inserted into the heat shrink tubing. Then, by controlling the action of the forward-pushing cylinder, the heat shrink tubing is pushed forward through the forward-pushing sliding sleeve until the front end of the heat shrink tubing is pushed onto multiple combined wire harnesses. At this time, the heat shrink tubing has covered the connection point of the mating terminal block.

[0047] 2. The present invention uses a sleeve method that adjusts the position of the heat shrink tubing by moving it from the direction of a single wire harness with an externally sleeved conduit towards the direction of multiple combined wire harnesses. The guide tube ensures a smooth and unobstructed sleeve process, reducing the failure rate during sleeve installation.

[0048] 3. Using this invention reduces the requirements for wire twist and heat shrink tubing aperture tolerance, while the failure rate is only 0.2%. In contrast, existing technologies have strict requirements for wire twist and heat shrink tubing aperture tolerance, resulting in a failure rate as high as 3%-5%. This invention, by using a heat shrink tubing of a single aperture specification, can complete the tubing operation for a single wire harness main line and two, three, or four wire harness auxiliary lines (i.e., achieving tubing switching modes of one-to-two, one-to-three, and one-to-four connections between the main and auxiliary lines). Existing technology uses one aperture specification for one-to-two and one-to-three connection modes, and another aperture specification for one-to-three and one-to-four connection modes. Since different models of heat shrink tubing have different procurement costs, using the tubing structure of this invention can save on heat shrink tubing procurement costs and reduce enterprise production costs.

[0081] Example 2

[0082] This invention also provides a method for using a multi-wire merging crimping machine for sleeves, comprising the following steps:

[0083] Step 1: Control the operation of the tube feeding and cutting mechanism 1. The specific process is as follows:

[0084] First, control the tube feeding motor 12 to work. Through the rotation of the drive gear 13, the driven gear 14, the conveying gear 15 and the conveying cylinder 16 are driven to rotate synchronously. Through the rotation of the left and right conveying cylinders 16, the heat shrink tube is driven to be conveyed forward to the pneumatic cutter 19 under the guidance of the guide tube 17 and the guide tube 2 18. When it is conveyed forward to a certain length, the pneumatic cutter 19 is controlled to work. The pneumatic cutter 19 automatically cuts the heat shrink tube to form a section.

[0085] Step 2: Control the operation of the first conveying mechanism 2. The specific process is as follows:

[0086] First, control the pneumatic gripper 27 to synchronously grip and hold the section of heat shrink tubing cut in step one. Then, control the transport motor 22 to drive the transport arm 25 and the pneumatic gripper 27 to move along the slide rail 26 in the left and right directions through the transmission of the synchronous pulley 23 and the synchronous toothed belt 24 until the pneumatic gripper 27 transports the tubing to the front position of the wire feeding sleeve mechanism 3.

[0087] Step 3: Control the operation of the wire feeding sleeve mechanism 3. The specific process is as follows:

[0088] First, the wire feeding assembly 32 is controlled to operate, specifically the wire feeding motor 322. This motor drives the first wire feeding gear 323 to rotate, which, in conjunction with the transmission belt 328, synchronously drives the second wire feeding gear 324, the third wire feeding gear 325, the fourth wire feeding gear 326, and the fifth wire feeding gear 327 to rotate. The second wire feeding gear 324 synchronously drives the lower conveyor wheel 330 to rotate, and the fifth wire feeding gear 327 synchronously drives the upper conveyor wheel 329 to rotate. The rotation of the upper conveyor wheel 329 and the lower conveyor wheel 330 drives the main wire, i.e., the single wire bundle, forward into the conduit 341 at the sleeve assembly 33, guided by the wire feeding guide tube 334 and the guide block 335. At this time, the linear control module 31 is activated, which means the external driver is activated to drive the transmission gear 315 to rotate. This drives the transmission shaft 313 and the transmission gear 314 to rotate synchronously. With the cooperation of the transmission gear 314 and the moving frame 316 with rack and pinion, the moving frame 316, the wire feeding assembly 32, and the sleeve assembly 33 are driven to move forward on the slide groove of the fixed platform 311 until the conduit 341 is moved forward and inserted into the heat shrink tubing clamped and fixed by the pneumatic claw 27 in step two. When the process of inserting the conduit 341 into the heat shrink tubing is completed, the first transport mechanism 2 is activated to return to its original position and wait for the clamping of the next section of heat shrink tubing.

[0089] Then, the wire feeding assembly 32 continues to operate, that is, by using the rotation of the upper conveyor wheel 329 and the lower conveyor wheel 330, the single wire harness is driven forward to be fed between the rear fixed V-shaped cutter 42 and the movable V-shaped cutter 43 in the stripping mechanism 4, and then continues to be fed forward to a certain distance, which does not exceed the distance between the front and rear fixed V-shaped cutters 42 or the movable V-shaped cutter 43.

[0090] Step 4: Control the operation of the peeling mechanism 4. The specific process is as follows:

[0091] First, control the external driver to work, drive the power gear 46 and the transmission gear 47 to rotate. With the cooperation of the transmission gear 47 and the moving plate 44 with meshing teeth, drive the moving plate 44 and the moving V-shaped cutter 43 on it to move upward until the single wire harness is stripped through the fixed V-shaped cutter 42 and the moving V-shaped cutter 43 on the rear side.

[0092] While the stripping action is in progress, the wire feeding assembly 32 is simultaneously controlled to work, that is, to drive the single wire harness to retract a certain distance so that the front end of the single wire harness is completely stripped of the wire harness outer sheath.

[0093] After the above stripping process is completed, continue to control the wire feeding assembly 32 to continue to work, that is, drive the single wire harness forward to continue to feed it to the crimping station of the terminal crimping mechanism 6;

[0094] Step 5: Control the second transport mechanism 5 to transport the auxiliary wires, i.e., multiple combined wire bundles, that have been transferred by the robot arm in the previous process to the pneumatic gripper 96 of the wire pulling mechanism 9. The working process of the second transport mechanism 5 here is the same as that of the first transport mechanism 2; the multiple combined wire bundles are clamped and fixed by the pneumatic gripper 96.

[0095] Step Six: First, control the terminal crimping mechanism 6 to complete the process of crimping the bare core ends of multiple combined wire harnesses and single wire harnesses.

[0096] When performing the above-mentioned terminal crimping action, it also includes:

[0097] The downward pressure cylinder 339 in the synchronous control sleeve assembly 33 is activated, causing it to drive the moving block 340 and the conduit 341 on it to move downward, that is, to drive the single wire harness in the conduit 341 to move downward until it moves to the crimping station.

[0098] The synchronous control of the pneumatically driven pressing block 8 causes it to complete the pressing process of the pneumatic jaw 96 by moving downward, that is, it drives the multiple combined wire harnesses clamped and fixed on the pneumatic jaw 96 to move downward until they move to the crimping station.

[0099] When the above-mentioned terminal crimping process is completed, the control cylinder 339 is activated to drive the single wire harness to return to its original position; the pneumatically driven pressing block 8 is activated to return to its original position. At this time, the pneumatic gripper 96 uses the elastic force of the spring rod to return to its original position, causing the multiple combined wire harnesses to return to their original positions. This ensures that during the following sleeve operation, the single wire harness and the multiple combined wire harnesses always maintain the same horizontal height, which can further ensure the smoothness and efficiency of the sleeve process.

[0100] Step 7: Control the forward push cylinder 342 in the sleeve assembly 33 to act, synchronously driving the forward push rod 343 and the forward push sliding sleeve 344 to move forward, pushing the heat shrinkable tube sleeved on the conduit 341 to move forward until the front end of the heat shrinkable tube is pushed and sleeved onto multiple bundled wire harnesses, and at this time, the connection point where the terminals are butt-connected is covered by the heat shrinkable tube; then control the pneumatic soldering iron 7 to move down, and heat the soldering iron to shrink and fix the heat shrinkable tube at the connection point where the terminals are butt-connected;

[0101] Step 8: Control the wire feeding assembly 32 and the wire pulling mechanism 9 to work. The specific process is as follows:

[0102] First, when the wire feeding assembly 32 works, it drives the single wire harness to continue to be conveyed forward;

[0103] Meanwhile, control the wire pulling mechanism 9 to work, that is, control the wire pulling motor 91 to work, drive the rotating gear 93 to rotate, and under the cooperation of the rotating gear 93 and the moving arm 94 with meshing teeth, drive the moving arm 94 and the pneumatic jaw 96 thereon to move forward along the slide seat 92, driving the multiple bundled wire harnesses to move forward; that is, through the cooperation of the above-mentioned wire feeding assembly 32 and the wire pulling mechanism 9, the wire harness after being butted and combined with the sleeve is conveyed forward until the length of the single wire harness conveyed out through the conduit 341 meets a certain length. At this time, control the stripping mechanism 4 to work, and use the fixed V-shaped cutter 42 and the moving V-shaped cutter 43 at the rear to cooperate to complete the cutting action on the rear end of the single wire harness; use the fixed V-shaped cutter 42 and the moving V-shaped cutter 43 at the front to cooperate to complete the peeling action on the rear end of the cut single wire harness.

[0104] When performing the peeling action on the rear end of the single wire harness as described above, it further includes: controlling the pneumatic jaw 96 in the wire pulling mechanism 9 to continue to move forward for a certain distance so that the rear end of the single wire harness is completely stripped of the wire harness outer skin.

[0105] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention according to the above disclosure shall fall within the protection scope of the claims.
