[0034] Combination Figure 3 , Figure 7 The two automatic apron feeding mechanisms 2 each include a vibration disk 21, a discharge guide rod 22 connected at one end to the discharge port of the vibration disk 21, and an apron storage seat 23 installed at the other end of the discharge guide rod 22. The vibration disk 21 automatically arranges the aprons in sequence and transports them to the apron storage seat 23, and the automatic apron picking unit 6 continuously picks up the aprons in the apron storage seat 23.

The feeding sensor 32 is electrically connected to the feeding finger cylinder 31; by placing the wire harness on the positioning block 34, the feeding sensor 32 senses that the wire harness is placed and feeds back a signal, prompting the feeding finger cylinder 31 to drive the two feeding claws 33 to move relative to each other to clamp the wire harness on the positioning block 34.

[0036] Combination Figures 3 to 9 The wire harness material transfer unit 4 includes a horizontal reciprocating drive member 41 installed on the frame 1, and a plurality of material transfer jaw cylinder assemblies 42 installed at intervals on the horizontal reciprocating drive member 41; the horizontal reciprocating drive member 41 is electrically connected to the feeding sensor 32; the horizontal reciprocating drive member 41 is any one of a motor screw transmission assembly or a gear tooth 623-622 transmission assembly or a ball screw transmission assembly or a cylinder horizontal driving assembly; the material transfer jaw cylinder assembly 42 is driven by the horizontal reciprocating drive member 41 to reciprocate between the feeding jaw 33 and the wire harness feeding unit 5, between the two groups of wire harness feeding units 5, and between the wire harness feeding unit 5 and the visual inspection and unloading unit 8, thereby realizing automatic loading and transferring of the wire harness, wire harness assembly, and wire harness unloading processes.

[0037] Both wire harness feeding units 5 include a horizontal feeding drive 51 installed on the frame 1 and a feeding claw cylinder assembly 52 installed on the horizontal feeding drive 51. The horizontal feeding drive 51 is a cylinder driving assembly, and the driving direction of the horizontal feeding drive 51 is arranged perpendicular to the driving direction of the wire harness shifting unit 4; the horizontal feeding drive 51 drives the feeding claw cylinder assembly 52 to reciprocate between the wire harness shifting unit 4 and the automatic leather ring picking unit 6, so as to pick up the wire harness on the wire harness shifting unit 4 and move it to the leather ring assembly unit 7.

[0038] The two automatic leather ring picking units 6 each include a vertical driving member 61 installed on the frame 1, a rotating unit 62 installed on the vertical driving member 61, a parallel opening and closing finger cylinder assembly 63 connected to the rotating unit 62, and shafts 64 respectively installed on multiple driving rods of the parallel opening and closing finger cylinder assembly 63; the parallel opening and closing finger cylinder assembly 63 controls the opening or gathering of the multiple shafts 64. When the parallel opening and closing finger cylinder assembly 63 controls the gathering of the multiple shafts 64, the multiple shafts 64 are columnar, and the diameter is adapted to the diameter of the leather ring, so that the leather ring is sleeved outside the multiple shafts 64 when gathered, thereby realizing the function of leather ring feeding.

[0039] The vertical driving member 61 drives the parallel opening and closing finger cylinder assembly 63 to reciprocate in the direction of the leather ring automatic feeding mechanism 2, and the rotating unit 62 controls the parallel opening and closing finger cylinder assembly 63 to rotate so that the shaft 64 corresponds to the wiring harness on the wiring harness feeding unit 5, and the leather ring assembly unit 7 acts on the shaft 64 to assemble the leather ring on the shaft 64 on the wiring harness on the wiring harness feeding unit 5.

[0040] Among them, the vertical driving member 61 is a cylinder driving assembly, and the rotating unit 62 includes a first cylinder 621 fixedly installed on the vertical driving member 61, a rack 622 connected to the first cylinder 621 driving member, a gear 623 meshing and transmission connected to the rack 622, and a rotating shaft 624 connected to the gear axis. The rotating shaft 624 is fixedly connected to the parallel opening and closing finger cylinder assembly 63, and the rotating shaft 624 is rotatably installed on the vertical driving member 61; the rack 622 gear is driven to operate by the first cylinder 621, thereby causing the parallel opening and closing finger cylinder assembly 63 connected to the rotating shaft 624 to rotate 180°.

[0041] The leather ring assembly unit 7 includes an assembly cylinder 71 installed on the rotating unit 62 and a pusher 72 installed on the assembly cylinder 71. The pusher 72 is arranged on the outer side of the shaft rod 64. The assembly cylinder 71 drives the pusher 72 to reciprocate along the axial direction of the shaft rod 64. When the parallel opening and closing finger cylinder assembly 63 controls the opening of multiple shaft rods 64, the multiple shaft rods 64 are hollow ring-shaped, and the leather ring is opened. At this time, the pusher 72 and the shaft rod 64 are in conflict.

[0042] After the rotating unit 62 drives the parallel opening and closing finger cylinder assembly 63 to rotate 180°, the horizontal feed drive 51 in the wire harness feeding unit 5 drives the feed clamp cylinder assembly 52 to move toward the parallel opening and closing finger cylinder assembly 63, and makes the wire harness on the feed clamp cylinder assembly 52 pass through the hollow space between multiple shafts 64. At this time, the parallel opening and closing finger cylinder assembly 63 controls the multiple shafts 64 to gather together and wrap around the outside of the wire harness. Then, the assembly cylinder 71 drives the pusher 72 to move along the axial direction of the shaft 64. The pusher 72 pushes the leather ring mounted on the multiple shafts 64 onto the wire harness, thereby realizing the function of automatic assembly of the leather ring on the wire harness.

[0043] Combination Figures 2 to 4 The visual material picking and unloading unit 8 includes a material picking driving member 81 installed on the frame 1, a material picking finger cylinder 82 installed on the driving rod of the material picking driving member 81, a material picking claw 83 installed on the driving rod of the material picking finger cylinder 82, and a visual material picking module installed on the frame 1. The visual material picking module is electrically connected to the wire harness moving unit 4, the wire harness feeding unit 5, and the material picking driving member 81; the material picking driving member 81 drives the material picking finger cylinder 82 to reciprocate toward the wire harness moving unit 4, and the material picking finger cylinder 82 drives the material picking claw 83 to clamp or release the wire harness.

[0044] The implementation principle is: first, place the wire harness to be processed on the positioning block 34 in the wire harness feeding unit 3. At this time, the feeding sensor 32 senses that the wire harness is placed, and then feeds back the signal to prompt the feeding finger cylinder 31 to drive the two feeding claws 33 to move relative to each other to clamp the wire harness on the positioning block 34; then, the horizontal reciprocating drive member 41 in the wire harness moving unit 4 drives the moving claw cylinder assembly 42 at the feeding claw 33 to clamp the wire harness at the feeding claw 33, thereby realizing the automatic loading and moving process of the wire harness.

[0045] At the same time, the parallel opening and closing finger cylinder assemblies 63 in the two groups of automatic leather ring picking units 6 control the multiple shafts 64 to gather in a columnar state, and the vertical driving member 61 drives the multiple shafts 64 to move toward the direction of the automatic leather ring feeding mechanism 2, so that the shafts 64 are inserted into the leather sleeves on the leather ring storage seat 23, and the leather sleeve automatic material taking process is realized; then, the vertical driving member 61 drives the multiple shafts 64 to return to their positions, and the parallel opening and closing finger cylinder assemblies 63 control the opening of the multiple shafts 64, and the multiple shafts 64 are hollow rings to open the leather rings; then, the first cylinder 621 in the rotating unit 62 prompts the rack 622 gear to operate, thereby driving the parallel opening and closing finger cylinder assemblies 63 to rotate 180°.

[0046] At the same time, the horizontal reciprocating drive member 41 in the harness moving unit 4 drives the moving clamping claw cylinder assembly 42 to reciprocate between the loading clamping claw 33 and the harness feeding unit 5 and the two sets of harness feeding units 5, so as to realize the automatic material transfer of the harness from the loading clamping claw 33 to the feeding clamping claw cylinder assembly 52, and then the feeding clamping claw cylinder assembly 52 in the harness feeding unit 5 picks up the wire speed on the feeding clamping claw cylinder assembly 52, and drives the feeding clamping claw cylinder assembly 52 to move in the direction of the parallel opening and closing finger cylinder assembly 63 through the horizontal feeding drive member 51, and makes the harness on the feeding clamping claw cylinder assembly 52 pass through the multiple shafts 6 4, at this time, the parallel opening and closing finger cylinder assembly 63 controls the multiple shafts 64 to gather together and wrap around the outside of the wiring harness, and the assembly cylinder 71 in the leather ring assembly unit 7 drives the pushing piece 72 to move along the axial direction of the shaft 64, and the pushing piece 72 pushes the leather rings sleeved on the multiple shafts 64 onto the wiring harness, thereby realizing the function of automatic assembly and placement of the leather rings on the wiring harness; similarly, the two groups of leather ring automatic picking units 6, the wiring harness feeding unit 5, and the leather ring assembly unit 7 have the same structure, and are driven differently by the first cylinder 621 in the wiring harness feeding unit 5 to realize the leather ring sleeve process at different positions of the wiring harness.

[0047] Finally, the wire harness moving unit 4 drives the moving clamping claw cylinder assembly 42 to reciprocate between the wire harness feeding unit 5 and the visual material checking and unloading unit 8 through the horizontal reciprocating driving part 41, and picks up the wire harness with the leather ring from the feeding clamping claw cylinder assembly 52 in the wire harness feeding unit 5 and transfers it to the material checking finger cylinder 82 in the visual material checking and unloading unit 8. The material checking finger cylinder 82 drives the material checking claw 83 to clamp the wire harness for visual inspection to determine whether the leather cover on the wire harness is successfully put on. If there is a difference, the wire harness moving unit 4, The wire harness feeding unit 5 and the material inspection driving member 81 stop moving, so as to facilitate the removal of the unqualified wire harness and restart the operation. If the apron is qualified, the material inspection finger cylinder 82 drives the material inspection claw 83 to open, so as to realize the wire harness unloading process. By sequentially arranging the wire harness loading unit 3, the wire harness moving unit 4, the wire harness feeding unit 5, the apron automatic picking unit 6, the apron assembly unit 7 and the visual material inspection and unloading unit 8, the automatic apron putting process of the wire harness end is realized, which has the effect of improving the processing efficiency of the wire harness products and reducing the labor intensity.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
