Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a wire harness cutting device for wire harness production. Background Art

[0002] The automotive wiring harness is the network backbone of the vehicle's electrical circuits. Without it, there would be no automotive circuits. A wiring harness is a component that connects electrical circuits by crimping copper contact terminals with wires and cables, then wrapping them with plastic-molded insulation or a metal casing.

[0003] Automotive wiring harnesses require a cutting process during production. Currently, manual assistance is required in pushing, transferring, and cutting the wire harnesses during the cutting process. Manual assistance is also required in measuring the lengths to complete the cutting. The degree of automation needs to be improved. In summary, the above problems in the wire harness cutting process need to be solved urgently. Utility Model Content

[0004] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes a wire harness cutting device for wire harness production.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A wire harness cutting device for wire harness production includes a processing table, on which is provided a rolling assembly for automatically conveying the wire harness without deviation, an automatic cutting assembly on one side of the rolling assembly, a blanking hole on one side of the automatic cutting assembly, and a blanking trough connected to the blanking hole, wherein an inclined table is provided in the blanking trough, and the automatic cutting assembly includes an upper cutter and a lower cutter with a V-shaped main body, and the two are staggered in the vertical direction and cooperate with each other.

[0007] This device does not require manual pushing and transfer for cutting the wire harness, and the position of the wire harness will not shift during the automatic roller conveying process. It automatically completes the cutting and unloading processes, and can achieve fixed-length cutting of the wire harness without the need for manual auxiliary measurement. The degree of automation and the use effect of the wire harness cutting device are better.

[0008] Furthermore, the rolling assembly includes an installation box, a first rotating roller and a second rotating roller. The installation box is provided on the processing table. The installation box is equidistantly and rotatably connected to a number of first rotating rollers at the same height and a number of second rotating rollers above the first rotating rollers and distributed and matched with the first rotating rollers in a one-to-one correspondence. A driving assembly is provided in the installation box and the driving assembly is connected to the second rotating rollers so that the several second rotating rollers move synchronously in the same direction. The first rotating roller and the second rotating roller are circumferentially provided with wire grooves adapted to the width of the wire harness to limit the position of the wire harness during the transmission process.

[0009] The above solution can realize the automatic non-offset loading and transfer of the wire harness to the lower cutter through the roller pressing component, and can also complete the subsequent fixed-length cutting.

[0010] Furthermore, the automatic cutting assembly includes a mounting frame, hydraulic equipment, a mounting plate, an upper cutter and a lower cutter. The mounting frame and the lower cutter are provided on the processing table. The mounting frame is provided with a hydraulic equipment, the hydraulic equipment is connected to the mounting plate, and the mounting plate is provided with an upper cutter.

[0011] The above solution realizes efficient cutting of the wire harness by automatic cutting components.

[0012] Furthermore, the processing table is provided with a screw assembly spaced apart from the blanking hole, the screw assembly is provided with a limit plate with an L-shaped main body, and the limit plate is provided with a pressure sensor in contact with the end face of the wiring harness.

[0013] The above scheme can change the cutting length of the wire harness by controlling the time interval of automatic start and stop of the roller pressure component through the controller to achieve fixed-length cutting. However, if the roller pressure component fails, it will not be able to start and stop accurately according to the pre-set time interval. If it stops early, the wire harness will not contact the limit plate. At this time, the force on the pressure sensor is 0, which is judged to be abnormal. If it does not stop in time, the wire harness will contact the limit plate and cause the pressure detection value to increase to an abnormal value beyond the standard value (the value range between the wire harness and the pressure sensor under normal start and stop is pre-set). In this way, fixed-length cutting can be completed more accurately.

[0014] Furthermore, a collection box is placed on one side of the processing table, and the end of the inclined table is above the collection box.

[0015] Furthermore, the driving assembly adopts chain transmission.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Compared with the existing technology, this device does not require manual pushing and transfer for cutting the wire harness, and the position of the wire harness will not be offset during the automatic roller conveying process. It automatically completes the cutting and unloading processes, and can achieve fixed-length cutting of the wire harness without the need for manual auxiliary measurement. The wire harness cutting device has a better degree of automation and use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0026] like Figures 1 to 5 As shown, a wire harness cutting device for wire harness production includes a processing table 1, on which is provided a rolling assembly for automatic conveying of the wire harness without offset, an automatic cutting assembly on one side of the rolling assembly, a blanking hole 13 on one side of the automatic cutting assembly, and a blanking trough 11 connected to the blanking hole 13, a ramp 12 is provided in the blanking trough 11, and the automatic cutting assembly includes an upper cutter 34 and a lower cutter 35 with a V-shaped main body, and the two are staggered in the vertical direction and cooperate with each other.

[0027] Further refinement of the embodiment of the present invention is as follows: Figure 1 and Figure 4 As shown, the rolling assembly includes an installation box 2, a first rotating roller 21 and a second rotating roller 22. The installation box 2 is provided on the processing table 1. The installation box 2 is equidistant and rotatably connected to a number of first rotating rollers 21 at the same height and a number of second rotating rollers 22 above the first rotating rollers 21 and distributed and matched with the first rotating rollers 21. A driving assembly is provided in the installation box 2 and the driving assembly is connected to the second rotating rollers 22 so that the several second rotating rollers 22 move synchronously in the same direction (specifically, the driving assembly adopts chain transmission, which belongs to the existing technical means and is not described and is not shown in the figure). The first rotating roller 21 and the second rotating roller 22 are circumferentially provided with a wire groove 23 adapted to the width of the wire harness to limit the position of the wire harness during the transmission process. It should be noted that the bottom surfaces of the wire grooves 23 on the upper and lower rotating rollers are in contact with the wire harness.

[0028] Further refinement of the embodiment of the present invention is as follows: Figures 1 to 3 As shown, the automatic cutting assembly includes a mounting frame 31, a hydraulic device 32, a mounting plate 33, an upper cutter 34 and a lower cutter 35. The mounting frame 31 and the lower cutter 35 are provided on the processing table 1. The hydraulic device 32 is provided on the mounting frame 31. The hydraulic device 32 is connected to the mounting plate 33. The upper cutter 34 is provided on the mounting plate 33.

[0029] Further refinement of the embodiment of the present invention is as follows: Figure 1 As shown, a collecting box 14 is placed on one side of the processing table 1 , and the end of the inclined table 12 is located above the collecting box 14 .

[0030] It should be noted that the drive assembly and the hydraulic device 32 are electrically connected to the controller, which is not shown in the figure.

[0031] The workflow of this utility model:

[0032] First, the end face of the wire harness passes through the wire groove 23 on the first connecting roller and the second connecting roller on the far left at the same time. At this time, the position of the wire harness is limited (the wire harness is not numbered in the figure). Then the controller controls the driving component to rotate the second connecting roller. At this time, under the action of the second connecting roller, the first connecting roller rotates synchronously to carry out directional transportation of the wire harness and the position of the wire harness will not shift during the transportation process. As the transportation progresses, the initial end of the wire harness will pass through between the first connecting roller and the second connecting roller on the far right, and then the wire harness will meet the lower cutter 35. The wire harness is in contact with each other and continues to move. The start and stop time interval of the roller pressing assembly is pre-set in the controller to limit the length of the wire harness cut each time, that is, fixed-length cutting is achieved. When the wire harness reaches the fixed length, the roller pressing assembly stops working. At this time, the controller controls the hydraulic device 32 to drive the upper cutter 34 to move downward. At this time, the upper cutter 34 will cooperate with the lower cutter 35 to cut the wire harness. The cut wire harness falls from the blanking hole 13 into the blanking chute 11 and moves along the inclined platform 12, and finally falls into the collection box 14 to complete collection. The above process is repeated to achieve the assembly line cutting of the wire harness.

[0033] Compared with the existing technology, this device does not require manual pushing and transfer for cutting the wire harness, and the position of the wire harness will not be offset during the automatic roller conveying process. It automatically completes the cutting and unloading processes, and can achieve fixed-length cutting of the wire harness without the need for manual auxiliary measurement. The wire harness cutting device has a better degree of automation and use effect.

[0034] In some embodiments, as Figure 1 and Figure 5As shown, the processing table 1 is provided with a screw assembly 41 spaced apart from the blanking hole 13, the screw assembly 41 is provided with a limit plate 42 with an L-shaped main body, the limit plate 42 is provided with a pressure sensor 43 in contact with the end face of the wire harness, and the screw assembly 41 and the pressure sensor 43 are also electrically connected to the controller;

[0035] This device can change the cutting length of the wire harness by controlling the time interval of automatic start and stop of the roller assembly through the controller to achieve fixed-length cutting. However, if the roller assembly fails, it will not be able to start and stop accurately according to the pre-set time interval. If it stops early, the wire harness will not contact the limit plate 42. At this time, the force on the pressure sensor 43 is 0, which is judged to be abnormal. If it does not stop in time, the wire harness will contact the limit plate 42 and cause the pressure detection value to increase to an abnormal value beyond the standard value (the value range between the wire harness and the pressure sensor 43 under normal start and stop is pre-set). In this way, fixed-length cutting can be completed more accurately.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
