Description

Automatic change sticky tape fixed point and wrap equipment

Technical Field

The utility model belongs to pencil production automation equipment field, concretely relates to can wrap equipment of sticky tape by automatic fixed point, location.

Background

In the field of harness production, the adhesive tape is widely used, and especially in the rear-end processing procedure of harness production, the harness is often required to be bundled at a fixed point by the adhesive tape for marking the position, preventing the harness from being scattered, or serving as the final bundling state of the harness. For example, the twisted cable on the wire twisting machine needs to be temporarily bound by adhesive tapes at two ends to prevent the twisted cable from being scattered in the transferring process; many wiring harnesses need to be taped at different positions before assembly for identification of the assembly position; for example, for some wire harnesses with low protection grade on automobiles, in order to reduce cost and light weight of the automobiles, the spaced point winding adhesive tape is adopted to replace the integral wrapping winding adhesive tape or protective sleeves (corrugated pipes and the like); the wire harness in the household appliance industry is in the form of interval bundling tapes as the final processing state of the wire harness.

If only 1-2 of the strands (branches) need to be taped, there is generally no great difference in the efficiency of taping achieved by manual taping by workers and automated equipment. In fact, the harnesses requiring the fixed-point adhesive tapes are generally long, and the adhesive tape binding points are numerous, and sometimes the number of the adhesive tapes to be bound on one harness (or on a branch) is up to twenty. Moreover, the position distribution size of the adhesive tape is changeable, and the requirement on the precision of the positioning size is high (generally, the tolerance is required to be within 5 mm). At present, aiming at the above-mentioned wire harness with more points needing to be bundled with adhesive tapes, the technical scheme similar to that shown in fig. 1 is generally adopted in the industry for operation: each size of wiring harness requires a custom tooling platen 2. The wire clamping seat 1 for integrally positioning the wire harness is arranged on the upper surface of the tool bedplate and used for quickly positioning the wire harness on the tool bedplate. And aiming at the number and the positions of each different wire harness tape wrapping, a tape wrapping position comparison piece 5 is arranged at a corresponding position on the tool bedplate. A worker firstly clamps and positions the wire harness 4 to be wrapped on the tool bedplate, then manually tears the adhesive tape raw material 6, and manually winds the adhesive tape on the corresponding position of the wire harness according to the position corresponding to the adhesive tape position contrast piece to form a wrapping completion adhesive tape 3. It is clear that such a conventional solution has significant drawbacks: the adhesive tape binding machine has the advantages of high labor intensity of workers, low production efficiency, low adhesive tape binding quality and binding position precision, easiness in omission of adhesive tape binding points, large number of required tool platens and the like.

It is therefore desirable to provide a tape point wrapping device solution that can be automated first.

Of course, the moving direction in the figures is only one of the forms, and based on the above principle, when the tape guide roller 816 fixed on the tape unwinding sliding base 820 is driven by the tape unwinding driving base 828 in one direction, the moving direction should be such that the stroke distance between the unwinding point and the non-return point of the tape 822 is increased, so that the tape can be pulled out of the tape roll. The non-return point here refers to the limit point of the adhesive tape 822 by the adhesive tape non-return means. In addition, the other side of the adhesive tape unwinding sliding seat 820 is connected with one end of an adhesive tape tensioning spring 821, and the other end of the adhesive tape tensioning spring 821 is tensioned on the machine head base plate 804, so that the unwound adhesive tape is always kept in a proper tensioning state, and winding and bonding phenomena cannot occur.

In the automatic rubber coating machine head 8 of the embodiment, the rubber tape cutting device is a rubber tape scissors 811 for cutting off rubber tapes, which adopts the principle of common scissors and consists of two jointed cutting blades, wherein one blade is set to be fixed, the other blade is set to be a movable blade, the movable blade is driven by a scissors driver 812, and the scissors driver can be a rotary cylinder, a motor and the like.

In the automatic rubber coating machine head 8 of the embodiment, the rubber tape non-return device comprises a rubber tape non-return pressure arm 813, a rubber tape guide seat 814 and a rubber tape non-return pressure arm cylinder 815, wherein the rubber tape non-return pressure arm 813 is a swing arm hinged on the base plate, and the rubber tape non-return pressure arm is matched with the rubber tape guide seat 814 to play a role in preventing the rubber tape from retracting when the rubber tape is unwound and also play a role in maintaining the posture of the rubber tape head after being cut when the rubber tape is cut. The adhesive tape 822 passes through the surface of the adhesive tape guide seat 814, the adhesive tape non-return pressure arm 813 is hinged on the machine head base plate 804, the adhesive tape non-return pressure arm cylinder 815 is driven to rotate around a hinged point, and one end of the adhesive tape non-return pressure arm cylinder 815 can be matched with the adhesive tape guide seat 814 to clamp and limit the adhesive tape 822 in the rotating process. The non-return action of the adhesive tape non-return device is actually powered by the adhesive tape non-return pressure arm cylinder 815, so that whether the adhesive tape is non-return operated or not can be controlled by controlling the adhesive tape non-return pressure arm cylinder 815.

In the automatic rubber coating machine head 8 of this embodiment, the rubber coating press block 810 is two blade-shaped elastic press blocks hinged to two sides of the opening slot of the rubber coating driving wheel 809, and the free ends of the two elastic press blocks are respectively compressed by involution under the spring force to form a tapered bell mouth with the mouth opening towards the inlet direction of the opening slot. After the wire harness 4 enters from the horn mouth, the wire harness 4 can be gradually pressed by up and down wrapping, so that the adhesive tape 822 is further bonded with the wire harness 4, and when the rubber wrapping driving wheel 809 rotates, the adhesive tape 822 which is not wrapped on the wire harness 4 can be further wound on the wire harness 4.

Based on the automatic encapsulation machine head 8, internal work such as wrapping, cutting and the like of an adhesive tape can be automatically completed, the method for encapsulating the wiring harness 4 by the automatic encapsulation machine head 8 is described in detail as follows:

s301: first, before starting the automatic wrapping tape, the automatic wrapping head 8 is initialized, and the tape inside the head is in a state shown in fig. 8: the open slot of the encapsulation wheel 809 faces the clamped wire harness 4, the adhesive tape head 831 is clamped by the adhesive tape clamping jaw 808 and crosses the inlet of the open slot of the encapsulation wheel 809 in a mode that the adhesive surface faces back to the rotation center of the encapsulation wheel 809, the adhesive tape unwinding sliding seat 820 is in a rear position, the adhesive tape is already in the longest unwinding state, and the adhesive tape 822 is unwound in advance; the adhesive tape non-return pressure arm 813 releases the non-return state.

S302: as shown in fig. 10, after the automatic encapsulation process is started, the tape clamping jaw 808 is first controlled to open, so that the tape head 831 is in a free state; then, the automatic encapsulation machine head 8 is driven to move towards the wire harness 4, so that the wire harness 4 is primarily bonded with the adhesive surface of the adhesive tape and the primarily bonded adhesive tape head 831 is driven to further move to the rotation center of the encapsulation driving wheel 809 (as shown in fig. 11), and the encapsulation pressing block 810 is tightly attached to the surface of the wire harness under the action of the spring force; the tape 822, now unwound, is also partially brought into the encapsulating position.

S303: after the wire harness 4 moves to the rubber coating wheel coating position with the tape head 831, as shown in fig. 12, the tape non-return arm cylinder 815 drives the tape non-return arm 813 to close and press the tape surface at the tape cutting position. When the adhesive tape non-return pressing arm 813 is closed to press the surface of the adhesive tape, the adhesive tape unwinding cylinder 827 drives the adhesive tape unwinding slide 820 to move in the adhesive tape unwinding direction, thereby unwinding the adhesive tape. When the tape is unwound, the piston rod of the tape unwinding cylinder 827 returns to the original position (the position shown in fig. 13). At the same time, the tape scissors 811 are driven by the scissors driver 812 to cut the tape.

S304: as shown in fig. 13, after the adhesive tape is cut off, the rubber coating wheel 809 is driven to rotate around the rotation center, so that the adhesive tape 822 is coated on the surface of the wire harness 4 under the pressing of the rubber coating pressing block 810, and the adhesive tape coating work of one wire harness coating position is completed;

s305: after the automatic taping head 8 is out of position with the wiring harness 4, the gripper arm swing cylinder 805 drives the gripper arm swing arm 806 upward to extend the open tape gripper 808 to the tape head 831, as shown in fig. 14. Then, as shown in fig. 14, the tape gripper 808 grips the tape head 831, and after the tape anti-jam arm 813 is released, the tape swing arm 806 goes back down to the original position to re-cross the tape 822 across the open slot entrance of the encapsulation wheel 809. As shown in fig. 15, the preparation work before the tape encapsulation is completed, the preparation work of the tape encapsulation and the cutting of the single point of the automatic encapsulation head is completed, and the next wire harness encapsulation is waited.
