Description

[0002] In the production of automotive wiring harnesses, in order to meet the connection requirements of different electrical components in the car, it is usually necessary to use tape to wrap multiple scattered wiring harnesses into bundles to facilitate the subsequent connection and installation of the wiring harnesses in the car.

[0003] Among them, point wrapping at multiple points on a strand of automotive wiring harness is a common way of wrapping adhesive tape, that is, wrapping adhesive tape at different positions in the axial direction of a strand of automotive wiring harness until the bundle wrapping operation is completed.

[0004] In the point winding operation of the automotive wiring harness, in order to ensure that the thickness of the tape wound at different points is consistent, it is usually necessary to cut the tape into sections of a fixed length and then wrap the fixed-length tape around the wiring harness; the existing tape is stored in rolls, and when the point winding operation of the automotive wiring harness is required, the end of the tape is first pulled manually, and after the end of the tape is pulled a fixed distance, the tape is cut and separated to obtain a fixed length of tape.

[0005] However, in the tape stored in rolls, the tape is bonded together, the bonding strength of the tape itself is not stable, and the resistance caused is also unstable; therefore, each time the tape is pulled, it will cause different degrees of tensile deformation, and the thickness of the tape actually cut will be thinner than the theoretical thickness, while the length of the tape cut is fixed, which will cause the thickness of the tape wrapped at different points on the same automotive wiring harness to fluctuate greatly, which cannot meet production regulations.

DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1 As shown, an embodiment of the present invention provides a tape detection and cutting machine for automobile wiring harness production, comprising: a frame 1; a placement roller 11, which is arranged on the frame 1 for placing tape rolls; a clamping assembly 2, which is used to clamp the end of the tape; a first linear drive assembly 31, which is used to drive the clamping assembly 2 to make a linear motion along the length direction of the tape; a carrier component 41, which is movably arranged on the frame 1; a detection component 42, which is rotatably arranged on the carrier component 41; a first contact, which is arranged on the detection component 42 and is located on the center plane in the thickness direction of the tape; a second linear drive assembly 32, which is used to drive the carrier component 41 to make a linear motion along the width direction of the tape, and can drive the detection component 42 to contact the tape and make the first contact contact the upper surface of the tape; a sensing component, which is used to sense the rotation angle of the detection component 42 and convert it into an electrical signal; a control terminal, which receives the electrical signal of the sensing component, calculates the actual thickness of the tape, and transmits the electrical signal to the first linear drive assembly 31 to compensate for the length of the tape.

[0020] For example, in a design, it is necessary to wrap N turns of tape with a theoretical thickness of T on an automobile wiring harness, and the theoretical length of the tape to be cut is S1; however, when the tape is stretched out from the roll, it is deformed to a certain extent, and the actual thickness of the tape is t, and t<T.

[0021] It can be known that the theoretical thickness of the tape wrapped around the automobile wiring harness is NT, and the actual thickness of the tape is t, then the actual number of turns of the tape is n=NT / t, thus the actual required tape length S=nπd+nπ(D-d) / 2; wherein d is the diameter of the first turn of tape wrapped around the automobile wiring harness, d=2t+the diameter of the automobile wiring harness; D is the diameter of the nth turn of tape wrapped around the automobile wiring harness, D=2nt+the diameter of the automobile wiring harness; similarly, the specific value of S1 can be obtained, and the length that needs to be compensated S2=S-S1.

[0022] Specifically, the control terminal may be a programmable logic controller, which automatically calculates the thickness of the adhesive tape and compensates for its length through a PLC programming language.

[0023] During specific use, first, the clamping component 2 clamps the end of the tape, the first linear drive component 31 is started, and drives the clamping component 2 to move a fixed distance to obtain a tape with a length of S1, and the first linear drive component 31 stops and stands by; the second linear drive component 32 is started, and drives the detection component 42 on the carrier component 41 to move until the first contact touches the upper surface of the tape. In the vertical direction, the first contact reaches the upper surface of the tape from the center plane in the thickness direction of the tape. The rotation angle of the detection component 42 is sensed by the sensing component and transmitted to the control terminal, and the control terminal knows the actual thickness t of the tape; then the length S2 of the tape that needs to be compensated is calculated based on the actual thickness t of the tape, and the electrical signal is transmitted to start the first drive component, driving the clamping component 2 to move a distance of S2, and finally the tape with an actual length of S is obtained.

[0024] In the present invention, the thickness of the tape can be measured in real time, and the number of turns of the tape wrapped around the automobile wiring harness can be increased by compensating the length of the tape, thereby compensating the thickness of the tape wrapped around the automobile wiring harness, which can effectively ensure that the thickness fluctuation of the tape wrapped at different points on the same automobile wiring harness is within the design tolerance range and meets the production regulations.

[0028] In specific use, under the action of gravity, the detection component 42 abuts against the barrier rod, and the detection component 42 is positioned and installed through the barrier rod. The encoder shaft is at a fixed rotation angle, and the angle value of β can be obtained by subsequently sensing the angle of rotation of the encoder shaft.
