Description

Technical Field

[0001] The invention relates to the technical field of wire harness production, in particular to an automatic production line for loosening wire harness ties. Background Art

[0002] In the wire harness manufacturing process, the wires that have been welded to the connectors need to be protected by sheathing. There are many types of sheaths, such as polyvinyl chloride tubes, rainproof cloths, nylon braided mesh sleeves, threaded wire tubes, PVC self-adhesive tapes, etc. In the sheathing process, the wire harness ends are first sorted, bundled, and bundled with cable ties. The cable ties are then connected to the equipment to arrange the wires into a patterned circuit, and then the sheathing process is performed to protect the wires from damage and make the harness a whole to facilitate the sheathing operation. After the sheath is installed on the wire harness, the cable ties need to be removed to complete the process. The existing cable ties are generally loosened by manually cutting the cable ties with scissors or releasing the self-locking of the cable ties to loosen the cable ties. To tie, people need to manually rotate the wire harness, turn the cable tie connection point to the appropriate cutting position, and then use tools to cut the cable tie connection point to achieve the purpose of loosening the tie. When using scissors, you must be careful to avoid cutting the sheath and damaging the sheath. At the same time, the fixed fork used to place the wire harness on the equipment will also hinder the scissors from cutting. The wire harness needs to be removed from the fixed fork or the wire harness needs to be pulled to move the cable tie away from the fixed fork before cutting. The work is cumbersome, and multiple cable ties are used on a wire harness, all of which need to be loosened, which makes the labor intensity of the workers high. Due to the uncertainty of manual cutting, the sheath may be cut, so the workers need to replace the sheath of the wire harness, which is inefficient.

[0003] To this end, an automatic production line for loosening wire harness ties is proposed, which automatically removes the ties through a loosening device, reducing the labor intensity of workers, liberating labor productivity, and improving work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic production line for loosening wire harness ties, which automatically removes the ties through a loosening device, reduces the labor intensity of workers, liberates labor productivity, and improves work efficiency, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An automatic production line for loosening wire harness ties includes a track, a support plate, a fixed fork and a control system. The track is a circular track with multiple support plates installed on it. A driving device such as a synchronous motor drives the track to operate so that the multiple support plates move on the track. The multiple process steps are separated and carried out through the circular track, and the ends of the wire harnesses are sorted, bundled and bundled through the cable ties, and the wire harnesses are sleeved and loosened. The support plate is tilted upward by 20°-45° to facilitate workers to work on the support plate. Multiple fixed forks for wiring are fixed on the support plate. The cable ties are used to bundle the wire harnesses. Through the tied knot The block is connected to the fixed fork to pull the wire harness, which is convenient for casing. Multiple fixed forks are fixed in position according to the wire harness wiring design plan to achieve standardized production. A loosening device for removing the tie tied to the wire harness is installed on the track side. The loosening device includes a pressure device for limiting the movement of the wire harness, a rotating device for positioning the tie connection point and a cutting device for cutting off the tie. The movement of the wire harness on the fixed fork is limited by the pressure device, and the tie connection point is rotated to the corresponding position by the rotating device. Finally, the tie connection point is cut off by the cutting device, thereby achieving the purpose of automatic tie loosening, reducing the labor intensity of workers, liberating labor productivity and improving work efficiency.

[0007] The pressurizing device includes: a bracket, a manipulator, a mounting block 1, a driving element 1, a mounting block 2 and a pressurizing block. The bracket is threadedly connected to the side of the track, and the manipulator is threadedly connected to the bracket. The manipulator is composed of two linear motion axes and one rotary motion axis or a multi-axis articulated manipulator. The linear motion axis can be a gear rack mechanism, a hydraulic cylinder mechanism and a linear module, etc., and the rotary motion axis can be a rotating platform or a rotary cylinder, etc. The bracket carries the manipulator and tilts downward to make the manipulator relatively parallel to the support plate, which is convenient for the programming and operation of the manipulator. The manipulator is threadedly connected to the mounting block 1, and the mounting block 1 is threadedly connected to the driving element 1. The driving element 1 can be: a cylinder, a hydraulic cylinder and an electric telescopic rod, etc. The output end of the driving element is threadedly connected to the mounting block 2, and the mounting block 2 is welded with a pressure block, and the pressure block is provided with an inner groove for accommodating the fixed fork fork head and a pressure port for pressurizing the wiring harness, and the pressure port is provided at the bottom of the side wall of the pressure block, and an opening is provided on the side wall of the pressure block to connect the inner groove. When the equipment is in operation, the manipulator moves above the fixed fork, and the rotating motion shaft rotates the pressure block, and the side wall with the opening 1 on the pressure block is aligned with the cable tie. When the driving element is operated, the fixed fork fork extends into the inner groove, and the wiring harness end without the cable tie falls into the pressure port and is pressurized by the top wall of the pressure port to limit movement. The wiring harness end with the cable tie is not contacted by the pressure block, so as to avoid the pressure block pressing on the cable tie and affecting the subsequent loosening step.

[0008] Preferably, the rotating device includes roller one, roller two, mounting plate one, a driving motor and a camera. The pressure block is provided with a pressure port on the side wall on which roller one and roller two are symmetrically mounted for rotation. Roller one and roller two are provided with patterns that increase the friction of the roller surface and are made of materials with a large friction coefficient, such as rubber and plastic. Mounting plate one is welded to mounting block two, and a driving motor is threadedly connected to mounting plate one. The driving motor is closed-loop controlled, and the output end of the driving motor is fixedly mounted to the rotating shaft on roller one through a coupling. A camera for photographing the position of the cable tie connection point is threadedly connected to mounting block two. The camera can use a COMS or CDD camera, etc. For these two cameras, the imaging transparency and sharpness of the CCD are very good under the same pixels, and the color reproduction and exposure can be guaranteed to be basically accurate. However, CMOS products often have average transparency, weak ability to restore the color of real objects, and poor exposure. Due to its own physical characteristics, the imaging quality of CMOS is still a certain distance away from that of CCD. However, due to its low price, high integration and low power consumption, it is still widely used in the camera field; the wire harness falls into the pressurized port and is restricted by the pressure of the top wall of the pressurized port, and the wire harness is pressed between the rollers 1 and 2. The driving motor drives the roller 1 to rotate clockwise, and the roller 2 supports the wire harness, and the wire harness moves upward into the space surrounded by the rollers 1, 2 and the top wall of the pressurized port. In the meantime, the roller drives the wire harness to rotate, and the cable tie tied to the wire harness rotates accordingly, and the camera takes real-time pictures until the connection point of the cable tie rotates to vertically upward. The camera shooting picture is reflected to the system, and the system controls the motor to stop rotating. By controlling the position of the cable tie connection point, the cutting device cuts off the connection point to complete the loosening of the cable tie, avoiding cutting the cable tie strip that is close to the wire harness and damaging the sheath on the surface of the wire harness; after the loosening step is completed, the driving element contracts, and the driving motor reverses at the same time, moving the wire harness downward out of the space surrounded by the roller one, roller two and the top wall of the pressurizing port to prevent the wire harness from being pulled out of the fixing fork.

[0009] Preferably, the cutting device includes a second mounting plate, a second driving element, a connecting rod and a blade, the second mounting block is welded with a second mounting plate, the second mounting plate is threadedly connected to the second driving element, the second driving element can be: a cylinder, a hydraulic cylinder and an electric telescopic rod, etc., the second mounting plate is provided with a second opening, two slide grooves are symmetrically provided on both sides of the second opening, the blade is slidably installed in the two slide grooves, the connecting rod is threadedly connected to the blade and the output end of the second driving element, and the blade is pushed by the second driving element to cut the cable tie connection point to complete the purpose of loosening the cable tie, the two slide grooves support the two sides of the blade to limit the left and right shaking of the blade, and the connecting rod is tilted downward to connect the blade, when the second driving element pushes the blade, the connecting rod presses the blade against the bottom of the slide groove, so that the blade moves stably at the bottom of the slide groove, and the cable tie connection point is positioned by the bottom edge of the slide groove to ensure the accurate positioning of the cut cable tie.

[0010] Preferably, a plurality of telescopic rods for sharing the load of the driving element 1 are installed on the mounting block 1, and the plurality of telescopic rods and the driving element 1 are commonly threadedly connected to the mounting block 2. The output end of the driving element 1 operates to drive the telescopic rods to extend, and the plurality of telescopic rods share the weight of the components borne by the output end of the driving element 1, thereby reducing the radial force on the output end of the driving element 1, avoiding the output end of the driving element 1 from bending due to large radial force for a long time, affecting the accurate working alignment of the loosening device, and improving the actual load capacity and working life of the driving element 1.

[0011] Preferably, a baffle is fixedly installed on the support plate to catch the fallen cable ties. When the loosening device loosens the wire harness on the support plate, the cut cable ties fall from the wire harness onto the support plate, and finally slide along the inclined surface of the support plate to the baffle. The fallen cable ties are collected by the baffle to prevent the cable ties from falling everywhere and affecting the hygiene of the production site, and also to prevent the cable ties from falling onto the track or other equipment and affecting the normal operation of production. The baffle is tilted upward and has convex edges on both sides to prevent the cable ties from rolling out of the baffle.

[0012] Preferably, the blade has an arc-shaped edge, and the fixed fork is provided with a cutting groove in which the blade cooperates with each other. The second driving element pushes the blade, and the arc-shaped blade cuts at the connection point of the cable tie, reducing the extrusion force directly acting on the connection point of the cable tie by the blade, reducing the degree of deformation of the cable tie under stress, making the cable tie easier to cut, and cooperating with the cutting groove, the blade is inserted into the cutting groove to completely cut off the connection point of the cable tie, and also avoids the blade hitting the fixed fork during cutting, making the blade blunt and difficult to cut next time.

[0013] Preferably, the pressure block is threadedly connected to a sensing pressure plate, and the mounting block is threadedly connected to a warning light. The sensing pressure plate and the warning light are electrically connected to prevent errors in the loosening device due to long-term operation, tool setting errors, and programming errors, which may lead to inaccurate alignment of the inner groove and the fixed fork, causing the pressure block to collide with the fixed fork, causing wear and even damage to the equipment. When this occurs, the sensing pressure plate contacts the fixed fork, and the sensing pressure plate transmits an electrical signal to the control system, which stops the equipment and energizes the warning light, which lights up to alert workers to the equipment operation error.

[0014] Preferably, a buffer element is fixedly installed in the inner groove, and the buffer element can be a spring or a soft block, etc. When the fixed fork is inserted into the inner groove, the top of the fixed fork rests on the buffer element, buffering the impact force brought by the driving element, reducing the vibration and wear caused by the contact between the fixed fork and the pressure block, and improving the service life of the equipment.

[0015] Preferably, the bottom of the support plate is threadedly connected with a plurality of universal wheels, and the support plate is moved by the universal wheels to a position corresponding to the loosening device. The universal wheels are provided with a self-locking mechanism to fix the support plate, and then the loosening device is started to loosen the wire harness on the support plate. This loosening device reduces the budget for configuring the track and reduces the equipment cost. For small-scale production, a large site space is not required to complete the production of the wire harness.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A loosening device for removing the cable ties tied to the wire harness is installed on the side of the track. The loosening device includes a pressure device for limiting the movement of the wire harness, a rotation device for positioning the connection point of the cable tie, and a cutting device for cutting off the cable tie. The pressure device limits the movement of the wire harness on the fixed fork, and the rotation device rotates the connection point of the cable tie to the corresponding position. Finally, the cutting device cuts off the connection point of the cable tie, thereby achieving the purpose of automatic cable tie loosening, reducing the labor intensity of workers, liberating labor productivity, and improving work efficiency.

[0018] 2. A buffer element is fixedly installed in the inner groove. When the fixed fork is inserted into the inner groove, the top of the fixed fork rests on the buffer element, thereby buffering the impact force brought by the driving element, reducing the vibration and wear caused by the contact between the fixed fork and the pressure block, and improving the service life of the equipment.

[0019] 3. The blade has an arc-shaped edge. The second driving element pushes the blade. The arc-shaped blade cuts at the connection point of the cable tie, reducing the extrusion force of the blade directly acting on the connection point of the cable tie, reducing the degree of deformation of the cable tie under stress, and making the cable tie easier to cut.

[0033] The track 1 is a circular track 1 with six support plates 2 installed on the track 1.

The support plates 2 are tilted 30 degrees upward, which is convenient for workers to work on the support plates 2. Multiple fixing forks 3 for wiring are fixedly installed on the support plates 2. The wire harnesses are tied with cable ties, and the knots tied with cable ties are stuck on the fixing forks 3 to pull the wire harnesses, which is convenient for casing. Multiple fixing forks 3 are fixed in position according to the wiring design scheme of the wire harness. A baffle 21 for catching fallen cable ties is fixedly installed on the support plate. The baffle 21 is tilted upward and has convex edges on both sides to prevent the cable ties from rolling out of the baffle 21. Two brackets 4 are fixedly installed on both sides of the track 1, and a manipulator 5 is fixedly installed on the bracket 4. The manipulator 5 is a three-axis manipulator 5 consisting of two linear modules and a rotating platform.

The pressure block 9 is provided with an inner groove 901 for accommodating the fork 3 of the fixed fork and a pressure port 902. The wire harness is pressurized through the top wall of the pressure port 902. , limiting the movement of the wiring harness, and the opening on the opposite side wall connects the inner groove 901 to prevent the pressure block 9 from applying pressure to the cable tie. A buffer element 19 is fixedly installed in the inner groove 901. The buffer element 19 is a soft block made of rubber and has the effect of shock absorption and sound absorption.

The camera 14 shoots in real time until the connection point of the cable tie rotates to vertically upward. The camera 14 shoots the picture and responds to the system. The system controls the motor 13 to stop rotating. The mounting block 8 is fixedly mounted with a mounting plate 2 15, and the mounting plate 2 15 is fixedly mounted with a driving element 2 16.

The blade 18 has an arc-shaped blade, and the fixed fork 3 is provided with a cutting groove 301 that cooperates with the blade 18.

[0034] Specific working process:

[0035] The workers use cable ties to organize and bundle the ends of the wire harnesses on the support plate 2, and then put the wire harnesses through the sleeves. After completion, the synchronous motor 13 drives the track 1 to operate so that the support plate 2 moves on the track 1 and moves under the loosening device. The manipulator 5 is started, and the three corresponding servo motors drive the two linear modules to move and the rotary platform to rotate, so that the pressure block 9 is aligned with the fixed fork 3, and the pressure port 902 is located above the wire harness without a cable tie. The driving element 1 7 is started, pulling the telescopic rod 20 and pushing the mounting block 2 8 and the pressure block 9. The inner groove 901 of the pressure block 9 is sleeved on the fork head of the fixed fork 3. The fixed fork 3 compresses the buffer element 19, and the wire harness is pressed between the roller 1 10 and the roller 2 11. The driving motor drives the roller 1 to rotate clockwise, and the roller 2 supports the wire harness. The wire harness moves upward into the space surrounded by the roller 1, roller 2 and the top wall of the pressure port. The inner wall of the pressure port 902 is against the wire harness, and the driving motor 13 continues to rotate, driving The wire harness and roller 2 11 rotate, and the cable tie tied on the wire harness rotates accordingly. The cable tie connection point rotates to vertically upward. The camera 14 captures the vertically upward cable tie connection point and feeds back to the system. The system controls the drive motor 13 to stop and at the same time controls the output end of the drive element 2 16 to extend and drive the connecting rod 17 and the blade 18. The blade 18 slides in the slide groove, and the curved blade 18 pulls and cuts the cable tie connection point. The blade 18 is inserted into the cutting groove 301, and the cable tie connection point is completely cut off. The waste of the cable tie slides along the support plate 2 to the baffle 21. The output end of the drive element 2 16 drives the connecting rod 17 and the blade 18 to retract. At the same time, the drive element 1 7 drives the pressure block 9 to retract. The drive motor 13 rotates counterclockwise to push the wire harness out. The manipulator 5 moves to another fixed fork 3 to cut the next cable tie until all the wire harness straps supported by a support plate 2 are cut by the above steps. The track 1 operates to move the support plate 2 to loosen the cable tie of the next panel.

[0036] If an error occurs in the loosening device, the driving element 7 drives the pressure block 9 to collide with the fixed fork 3, and the fixed fork 3 hits the induction pressure plate 22 on the pressure device. The induction pressure plate 22 transmits an electrical signal to the control system, and the control system stops the operation of the equipment and energizes the warning light 23. The warning light 23 lights up to remind workers that the equipment is operating incorrectly.

[0037] For example 2, please refer to Figure 9 Different from the first embodiment, the track 1 is not used to move multiple support plates 2. Four universal wheels 24 are fixedly installed at the bottom of the support plate 2. The support plate 2 is moved by the universal wheels 24 to a position corresponding to the loosening device. The universal wheels 24 are provided with a self-locking mechanism to fix the support plate 2, and then the loosening device is started to loosen the wire harness on the support plate 2.

[0038] Compared with Example 1, Example 2 reduces the budget for configuring the track 1 and the equipment cost. By moving a support plate 2 through the universal wheel 24, the space requirement for track layout is reduced, and no large site space is required to complete the production of wire harnesses. In contrast, Example 1 drives multiple support plates 2 through the track 1, and simultaneously performs wire harness processing on multiple support plates 2. A large number of standardized wire harnesses can be produced, but a large site space and budget are required to arrange the track for wire harness production.

[0039] In summary, by comparing Example 1 and Example 2, both small-batch production and large-batch production need to change the position of the fixed fork 3 according to the wiring harness setting pattern. If small-batch production and the site space is small, choose Example 2, change the position of the fixed fork 3 on the individual support plate 2, and carry out wiring harness production; if large-batch production and the site space is large, choose Example 1, change the position of the fixed fork 3 of all support plates 2 on the track 1, and carry out mass production.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
