DETAILED DESCRIPTION

[0036] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0037] Embodiment 1:

[0038] like Figure 1-8As shown in the figure, the automatic wire harness end installation machine provided by the present utility model includes: a frame 1, on which a conveying mechanism 2 for horizontally conveying the wire harness is installed. The conveying mechanism 2 adopts a step-by-step conveying method. After each time the wire harness is conveyed forward by a fixed distance, it pauses for a certain period of time, and then conveys the wire harness forward again. This is repeated to achieve the purpose of intermittent wire harness conveyance. Along the wire harness conveying direction, a wire harness restraint mechanism 3, a wire harness de-shelling mechanism 4, a wire splitting mechanism 5, a terminal installation mechanism 6, a terminal housing installation mechanism 7, and an auxiliary fixing mechanism 8 are successively installed on the frame 1. It should be noted that the wire harness restraint mechanism 3 and the wire harness de-shelling mechanism 4 are aligned. The wire harness restraint mechanism 3 uses a cylinder as the driving force. The cylinder drives the pressing block to press and fix the wire harness on the conveying plane of the frame 1, so that the wire harness will not move when the outer shell is removed. The cylinder drives the pressing block to rise and reset, releasing the restriction on the wire harness, and the wire harness can then move forward. The wire harness de-shelling mechanism 4 includes a bracket 22 installed on the frame 1. An electric push rod 23 is installed on the bracket 22. The output end of the electric push rod 23 is installed with a first cutting assembly 24 and a second cutting assembly 25. The first cutting assembly 24 includes two symmetrically installed upper and lower cutters adapted to the outermost wire harness protective shell. The cutters are driven by a cylinder and can move up and down. The two cutters approach each other to cut off the outermost protective shell of the wire harness. The second cutting assembly 25 has a similar structure to the first cutting assembly 24 and will not be described in detail here. The second cutting assembly 25 is used to cut off the inner protective shell of the wire harness. The first cutting assembly 24 is in front of the second cutting assembly 25. When the first cutting assembly 24 and the second cutting assembly 25 cut off the inner and outer protective shells, the electric push rod 23 is activated to pull the first cutting assembly 24 and the second cutting assembly 25 outward, pulling off the outermost protective shell of the previous wire harness and the inner protective shell of the current wire harness from the wire harness. Thus, when the wire harness passes through the first cutting assembly 24 and the second cutting assembly 25 in sequence, the outer protective shell and the inner protective shell are respectively removed. Two guide rods 26 are slidably installed on the bracket 22. One end of the guide rod 26 is connected to the output end of the electric push rod 23. Through the guide rods 26, the support stability of the first cutting assembly 24 and the second cutting assembly 25 is improved. The wire splitting mechanism 5 includes a vertically installed and automatically liftable wire splitting plate and a cylinder for driving the lifting of the wire splitting plate. The bottom end of the wire splitting plate is inserted between the two metal wire ends of the lower wire harness, further squeezing the two metal wires apart to the two sides by a certain distance to facilitate the terminal to be sleeved on the end of the metal wire. The terminal installation mechanism 6 adopts the structure of the existing publicly disclosed automatic terminal installation equipment and will not be described in detail here. It can automatically fix and install the metal terminal on the end of the metal wire. The terminal housing installation mechanism 7 also adopts the structural design of the existing automatic terminal housing installation equipment and can fix and install the plastic housing of the terminal on the metal terminal. The cylinders or other electrical devices mentioned above are all controlled by a PLC to achieve automatic operation, and only manual feeding is required.During use, the wire harness is evenly placed on the conveying mechanism 2. The conveying mechanism 2 intermittently conveys the wire harness. When the wire harness passes through the wire harness restraint mechanism 3 and the wire harness de-shelling mechanism 4, the wire harness restraint mechanism 3 fixes the wire harness for a short time. The first cutting assembly 24 and the second cutting assembly 25 on the wire harness de-shelling mechanism 4 cooperate with the electric push rod 23 to remove the outer shell of the wire harness. When the wire harness passes through the wire splitting mechanism 5, the terminal installation mechanism 6, and the terminal housing installation mechanism 7, the wire harness is successively subjected to wire separation, metal terminal installation, and terminal housing installation. Finally, the wire harness leaves and drops from the tail of the conveying mechanism 2.

[0039] By setting the frame 1, the conveying mechanism 2, the wire harness restraint mechanism 3, the wire harness de-shelling mechanism 4, the wire splitting mechanism 5, the terminal installation mechanism 6, and the terminal housing installation mechanism 7, the entire process from the de-shelling of the wire harness to the installation of the metal terminal and the terminal housing can be automatically completed, with more comprehensive functions. The wire harness processing procedures can be completed on one device, making it more convenient to use.

[0040] Embodiment 2:

[0041] As Figure 1-2 shown, the auxiliary fixing mechanism 8 includes a plurality of auxiliary cylinders installed on the frame 1. A pressing plate is installed at the bottom end of the auxiliary cylinder. When the wire harness stops, the pressing plate descends under the driving action of the auxiliary cylinder and presses the position of the wire harness near the end, so that the wire harness is not easily bent or moved when installing the metal terminal and the plastic housing of the terminal, resulting in the terminal or housing not being installed in place, causing defects or even scrapping.

[0042] By setting the auxiliary fixing mechanism 8, the wire harness can be assisted in fixing, preventing the wire harness from being bent or moved when installing the metal terminal and the housing, which is beneficial to improving the product yield.

[0043] Embodiment 3:

[0044] As Figure 3-6 and Figure 8As shown in the figure, the conveying mechanism 2 includes two conveying wheels 9 installed on one side of the frame 1. A conveyor belt 10 is installed on the conveying wheels 9. The conveyor belt 10 is driven by a conveying component 11 installed inside the frame 1. Above the conveyor belt 10, there is a pressing plate 12. The pressing plate 12 is connected to the frame 1. A plurality of card slots 17 are evenly installed on the outer side of the conveyor belt 10. The intermittent conveying distance of the conveyor belt is a non-zero natural number multiple (i.e., 1, 2, 3, 4...) of the distance between the card slots 17. During use, the driving component intermittently drives the conveyor belt 10 to move, causing the conveying wheels 9 to rotate and the card slots 17 to move a certain distance (a distance that is a non-zero natural number multiple of the length of the distance between the card slots 17). The wire harness is placed on the card slots 17 and clamped. As the conveyor belt 10 moves, the wire harness moves under the pressing plate 12 and is pressed by the pressing plate 12 in the card slots 17 until the wire harness moves out of the pressing plate 12. As the conveyor belt 10 moves, the wire harness falls off from the card slots 17.

[0045] By setting the conveying mechanism 2 including the conveying wheels 9, the conveyor belt 10, the conveying component 11 and the pressing plate 12, and evenly installing the card slots 17 on the conveyor belt 10, the movement of the wire harness can be conveniently conveyed.

[0046] Embodiment 4:

[0047] As Figure 3-6 and Figure 8 shown in the figure, an annular limiting groove 16 is formed on the conveying wheel 9. A plurality of clamping blocks 15 are evenly installed on the inner side of the conveyor belt 10. The number of clamping blocks 15 is the same as the number of card slots 17. During use, the clamping blocks 15 are stuck in the annular groove 16 and rotate, so that the conveyor belt 10 will not axially shift.

[0048] By setting the clamping blocks 15 and the limiting groove 16, axial limiting of the conveyor belt 10 can be carried out to prevent axial movement of the conveyor belt 10 during operation.

[0049] Embodiment 5:

[0050] As Figure 4 and Figure 8As shown in the figure, the conveying assembly 11 includes a composite driving member 13 installed inside the frame 1 and a support plate 14 installed on top of the composite driving member 13. The composite driving member 13 can drive the support plate 14 to move horizontally and can also drive the support plate 14 to lift. A plurality of toggle rods 18 are fixedly installed on one side of the support plate 14. The spacing of the toggle rods 18 is a non-zero integer multiple of the spacing of the clamping blocks 15, and the width of the toggle rods 18 is slightly smaller than the width of the gap formed between the clamping blocks 15. Therefore, the toggle rods 18 can be inserted into the gap between the clamping blocks 15. When in use, the composite driving member 13 drives the support plate 14 to move horizontally so that the toggle rods 18 are aligned with the gaps between the clamping blocks 15. Then the toggle rods 18 rise and are inserted into the gaps. The toggle rods 18 translate to drive the conveyor belt 10 to move. After pausing for a period of time, then the toggle rods 18 descend, repeating the previous steps, thereby realizing the intermittent movement of the conveyor belt 10.

[0051] By providing the conveying assembly 11 including the support plate 14 on top of the composite driving member 13, the intermittent movement of the conveyor belt 10 can be realized.

[0052] Embodiment 6:

[0053] As Figure 4 and Figure 8 shown, a plurality of pneumatic chucks 19 are evenly installed on the top of the support plate 14. The spacing of the pneumatic chucks 19 is the same as the spacing of the card slots 17 and they are aligned one by one. The pneumatic chucks 19 protrude from the gap in the frame 1. When in use, after the support plate 14 rises, the pneumatic chucks 19 are aligned with the wire harness above and clamp it to fixedly support the end of the wire harness, so that when the conveyor belt 10 moves the wire harness, it effectively supports the wire stripping part of the wire harness, preventing the wire harness from bending or swinging due to inertia during movement, keeping the end of the wire harness straight, making it more convenient to align and install the metal terminals and the terminal housing. When the support plate 14 descends, the pneumatic chucks 19 release the wire harness.

[0054] By evenly installing a plurality of pneumatic chucks 19 on the top of the support plate 14, it can prevent the wire harness from bending during movement and facilitate the installation of the terminals.

[0055] Embodiment 7:

[0056] As Figure 8 shown, an insertion joint 20 is provided on the frame 1. The insertion joint 20 is located directly below the wire dividing plate of the wire dividing mechanism 5. When in use, the wire dividing plate descends and is inserted into the insertion joint 20, which can prevent the hard contact between the wire dividing plate and the frame 1, resulting in the extrusion and deformation damage of the end of the wire dividing plate, and is beneficial to extend its service life, thereby extending the service life of the wire dividing mechanism 5.

[0057] By providing the insertion joint 20 on the frame 1, it is beneficial to extend the service life of the wire dividing mechanism 5 and reduce the use cost.

[0058] Embodiment 8:

[0059] As Figure 9 shown, a thin plate 27 with both ends upturned is installed at the bottom of the pressing plate 12. A plurality of plug connectors 28 are installed on the top of the thin plate 27. The top ends of the plug connectors 28 are inserted into the pressing plate 12, and a spring 29 is sleeved on the plug connectors 28. Therefore, the thin plate 27 is elastically connected to the pressing plate 12. During use, the wire harness is stuck in the card slot 17. Under the action of the spring 29, the thin plate 27 presses the top of the wire harness, so that the wire harness is constrained in the card slot 17.

[0060] By setting the thin plate 27, the plug connectors 28 and the spring 29, the thin plate 27 is elastically installed at the bottom of the pressing plate 12, which can elastically constrain the wire harness and prevent the wire harness from being damaged due to hard pressing.

[0061] Embodiment 9:

[0062] As Figure 8 shown, a waste box 21 is installed on one side of the frame 1. The waste box 21 is arranged below the wire harness de-shelling mechanism 4 and is used to collect the peeled wire harness outer shells. During use, the wire harness de-shelling mechanism 4 removes the wire harness outer shell, and the removed outer shell falls into the waste box 21, which is convenient for subsequent centralized processing.

[0063] By installing the waste box 21 on the frame 1, it is convenient to collect the wire harness outer shells and facilitate centralized processing.

[0064] Working principle: During use, the wire harness is evenly placed on the conveying mechanism 2. The conveying mechanism 2 intermittently conveys the wire harness, so that when the wire harness passes through the wire harness constraint mechanism 3 and the wire harness de-shelling mechanism 4, the wire harness constraint mechanism 3 fixes the wire harness for a short time, and the first cutting assembly 24 and the second cutting assembly 25 on the wire harness de-shelling mechanism 4 cooperate with the electric push rod 23 to remove the outer shell of the wire harness. When the wire harness passes through the wire splitting mechanism 5, the terminal installation mechanism 6, and the terminal outer shell installation mechanism 7, the wire harness is successively subjected to wire separation, metal terminal installation, and terminal outer shell installation. Finally, the wire harness leaves and falls from the tail of the conveying mechanism 2.
