[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-5 The automatic wire laying device for automobile wire harness in the embodiment comprises an operating table 1, a wire laying part, a feeding and cutting part, a wire pulling part and a blanking part are installed on the tabletop of the operating table 1 from left to right, and a bearing table 25 is fixed and connected with the feeding and cutting part and located below the wire pulling part; the feeding and cutting part is divided into a feeding part and a cutting part, the feeding part comprises an upper table 7 fixed on the operating table 1, a guide plate 8 is fixed on the inner side of the upper table 7, two long plates are formed on the top of the guide plate 8, and a driving roller 9 and an upper roller 40 symmetrically arranged above and below the driving roller 9 are further installed on the inner side of the upper table 7, and a pressing end is installed in the cutting part.

[0023] In the above structure, the wire roll is installed on the pay-off part, the wire harness can be guided to the guide plate through the pay-off part, the two long plates can play a limiting role, the wire segment is placed with a large front and rear offset angle, then passes through between the driving roller and the upper roller, and then passes through the pressing end on one side, then moves to the right under the driving action of the driving roller and the action of the upper roller, so as to pass through the cutting part until the wire head is moved to the carrying table, then the wire harness is pulled to a certain length through the cooperation between the pulling part, the driving roller and the upper roller, the cutting part cuts off the wire harness, and the pressing end also tightens the wire harness, avoiding movement of cutting, and facilitating the position of the wire harness after cutting to be held and stayed, facilitating the next conveying, the pulling part moves the wire harness to the discharging part to complete collection, so that automatic pulling, cutting and collection can be realized, and the pulling part is reset after cutting, and the above operation is cycled to improve production efficiency.

[0024] As Figure 1 , the pay-off part includes a vertical plate 2 fixed on the operation table 1, a wire reel 3 for installing a wire roll is rotationally connected to the vertical plate 2, a driving motor 4 in transmission connection with the wire reel 3 is installed, and a tensioning roller 5 is installed, and two auxiliary rollers 6 are further installed on the vertical plate 2, and the inner side of the upper table 7 is also provided with the auxiliary rollers 6. The wire roll is installed through the wire reel, then one end of the wire roll is guided through the auxiliary roller and the tensioning roller and moved to the guide plate between the guide driving roller and the upper roller, and then passes through the pressing end on one side, when the pulling part pulls the wire harness, the driving motor simultaneously drives the wire reel to rotate, and the driving roller and the upper roller cooperate to convey the wire harness, so that the pay-off process is smooth.

[0025] Wherein, the front and rear sidewalls of the upper table 7 are fixed with side blocks 10, the waist holes are formed in the side blocks 10, the upper roller 40 is located in the waist hole of the two side blocks 10 and rotates, the sleeve 39 located above the upper roller 40 is slidably connected in the waist hole, the bottom of the sleeve 39 is fixed with a spring 12, and the side block 10 is threadedly connected with a screw rod 11 rotationally connected with the top of the sleeve 39. The upper roller can slide up and down in the waist hole, when moving upward, the spring 1 is extruded to play a buffering role, and the sleeve can be driven to move downward or upward through the rotation of the screw rod, so that the downward pressure of the spring 1 can be adjusted.

[0026] In addition, the cutting part includes linear modules 13 installed on the front and rear sidewalls of the upper table 7, a cutting knife 14 is fixed between the moving ends of the two linear modules 13, and the pressing ends are respectively installed on the cutting knife 14 and the two linear modules 13. During the conveying process of the wire harness, the wire harness first passes through the pressing end on the linear module, then passes through the cutting knife, and then passes through the pressing end on the cutting knife, when the pulling part pulls the wire harness to a specified length, the pressing end on the linear module first tightens the wire harness, then the linear module drives the cutting knife to cut off the wire harness, and in the cutting process, the pressing end on the cutting knife tightens the wire harness together with the carrying table to complete the cutting.

[0027] like Figures 3-5 ,by Figure 3 As shown in the diagram, the clamping end is divided into a left clamping end and a right clamping end. The left clamping end includes a side plate 16 fixed between the front surfaces of the two linear modules 13, and an upper moving plate 15 fixed between the moving ends of the two linear modules 13 located below the cutter 14. The side plate 16 is U-shaped and docks with the support platform 25. The upper surface of the side plate 16 is on the same horizontal plane as the table surface of the support platform 25. Two guide rods 18 are threaded through the side plate 16. A pressure plate 19 is fixed between the top ends of the guide rods 18, and a base plate 17 fixed to the upper moving plate 15 is fixed between the bottom ends of the guide rods 18. When the wire harness is pulled to the moving length, it moves through the lower moving end of the linear module, causing the upper moving plate to move down, so that the base plate moves the guide rods accordingly, until the pressure plate is close to the side plate, thus clamping the wire harness and preventing it from deviating after subsequent cutting.

[0028] The right pressure end includes a side block 20 fixed to the back of the cutter 14. The side block 20 has two through holes, and an inner block 22 is fixed inside each hole. A second spring 23 is fixed to the bottom of the inner block 22, and a positioning block 24 is fixed between the bottoms of the two second springs 23. A column 21, fixed to the positioning block 24, passes through the inner sides of the inner block 22 and the second spring 23. The bottom of the positioning block is not on the same horizontal plane as the bottom of the cutter. Therefore, when the cutter cuts the wire harness, the positioning block first presses the wire harness down and fixes it via the support platform. Simultaneously, as the cutter continues to press down, the positioning block drives the column upward, compressing the second spring, thus providing a buffer. This compresses the wire harness at both ends, preventing it from moving and affecting the cutting. When the cutter resets, the spring force of the second spring also drives the positioning block to reset.

[0029] like Figure 1 The wire pulling section includes a moving device 26 fixed on the operating table 1. A lower-push cylinder 27 is mounted on the moving end of the moving device 26. A lower-push plate 28, which slides against the front of the lower-push cylinder 27, is fixed to the piston rod of the lower-push cylinder 27. A clamping cylinder 29, located above the support platform 25, is mounted on the bottom of the lower-push plate 28. When the wire harness is conveyed to the head on the support platform via the drive roller and the upper roller, the clamping end of the clamping cylinder 29 opens to its maximum. Then, the lower-push cylinder drives the lower-push plate to move downwards, thereby causing the clamping cylinder 29 to move downwards simultaneously. This positions one end of the wire harness head between the clamping ends of the clamping cylinder 29. The clamping end of the clamping cylinder 29 then closes to clamp and fix the wire harness. The moving device 29 then moves the wire harness, pulling it to the specified length.

[0030] The operation table 1 is further provided with a horizontal moving device 30, the moving end of the horizontal moving device 30 is fixedly provided with a horizontal moving table 31, and the horizontal moving table 31 is internally provided with a receiving tray 32. After the wire harness is pulled to a certain length and cut off, the cut-off wire harness is transferred to the receiving tray through the pulling device and is placed in the receiving tray. When a certain amount of wire harnesses are placed in the receiving tray, the horizontal moving device drives the horizontal moving table to move, so that the receiving tray can be moved to a designated position for collection.

[0031] In addition, as Figure 2 The operation table 1 is further provided with a horizontal moving device 30, the moving end of the horizontal moving device 30 is fixedly provided with a horizontal moving table 31, and the horizontal moving table 31 is internally provided with a receiving tray 32. After the wire harness is pulled to a certain length and cut off, the cut-off wire harness is transferred to the receiving tray through the pulling device and is placed in the receiving tray. When a certain amount of wire harnesses are placed in the receiving tray, the horizontal moving device drives the horizontal moving table to move, so that the receiving tray can be moved to a designated position for collection.

[0032] The working principle of the above embodiment is as follows:

[0033] First, the wire roll is installed in the wire disc, and then the wire harness is guided to pass between the driving roller and the upper roller through the auxiliary roller, the tensioning roller and the guide plate, and is transferred to the side plate. The upper moving plate is driven downward by the linear module, the bottom plate is synchronously moved, the wire harness is pressed and fixed by the pressing plate driven by the guide rod, so that the preliminary operation of the wire harness is completed. The bottom plate is lifted up by the upper moving plate, the driving roller and the driving motor are operated, the wire harness is conveyed forward, and a section of the wire harness is moved to the supporting table. The wire harness is clamped and fixed by the clamping cylinder one when the lower top plate is driven downward by the lower top cylinder. The lower top plate is moved to the right side by the moving device one, and the wire harness is moved to a designated position. The lower end moving end of the linear module is operated to drive the pressing plate to press the wire harness again, and the upper end moving end is operated to drive the cutter to press down. At this time, the positioning block is pressed first, the cutter continues to press down, the positioning block drives the vertical column to move upward and press the spring two. The spring two plays a buffering role. When the cutter rises, the spring two drives the positioning block to reset. After the wire harness is cut off, the positioning block is reset, and then the wire harness is moved to the receiving tray by the moving device one. When a certain amount of wire harnesses are collected, the horizontal moving device drives the horizontal moving table to move, so that the receiving tray is located below the connecting plate. The connecting plate is driven downward by the screw rod device, the receiving tray is clamped and fixed by the clamping cylinder two, and the receiving tray is moved to the conveying table by the moving device two. The receiving tray is placed on the conveying table by the cooperation of the screw rod device and the clamping cylinder two, and is transferred to other processes by the conveying table.

[0034] In summary, the wire laying, wire pulling and wire cutting can be completed automatically, so as to reduce the manual intervention, improve the efficiency and reduce the error.
