Description

Technical Field

[0001] The invention relates to the technical field of wire harness winding, and in particular to a wire harness winding mechanism. Background Art

[0002] Wire harness winding is a common process technology in the automotive, aerospace, electronics and electrical industries. It is mainly used to fix a wire harness consisting of multiple cables (for example, grouping wires or cables according to function or voltage level) together with a winding tape (such as strapping tape or insulating tape) to form the wire harness into a predetermined shape and size.

[0003] In the prior art, a wire harness winding mechanism is usually used to wind the wire harness. The existing wire harness winding mechanism, such as a Chinese patent document with announcement number CN111942957B, discloses a device for winding air-conditioning wiring, which includes a base, a ring A, an electric drive module, a ring B, a square frame and a winding mechanism, wherein two rings B driven by the electric drive module are rotatably matched between two coaxial rings A symmetrically mounted on a mobile base, and a square frame is fixed between the two rings B, and a detachable winding mechanism is installed in the square frame; the winding mechanism rotates synchronously with the two rings B driven by the electric drive module to ensure that the winding belt continuously tightens the pipe harness during the rotation of the winding belt around the pipe harness, thereby improving the winding effect of the winding belt on the pipe harness.

[0004] When the wire harness winding mechanism in the above-mentioned prior art is working, multiple parallel cables are first gathered into a wire harness, and then the wire harness is passed through the winding device in sequence from the beginning to the end along its length direction, and one end of the winding belt is connected to the head end of the wire harness. Multiple wire harnesses gradually pass through the winding device, and the winding device drives the winding belt roll to move along a circular trajectory, so that the winding belt is wound around the outside of the wire harness to complete the winding operation of the wire harness, thereby binding, fixing and protecting the wire harness, and making the wire harness after winding have good tensile strength and corrosion resistance.

[0005] However, the above patent document still has the following shortcomings: when the winding belt moves along a circular trajectory, it will generate radial tension on the wire harness and extend in a straight line along the axis of a cable, causing the cable to twist and thus unable to extend in a straight line. Moreover, the twisted cable is separated from the original radial arrangement position, which is easy to be confused during subsequent maintenance and makes it difficult to perform maintenance operations.

DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 8 As shown, the wire harness winding mechanism of the present invention includes a winding mechanism 1, a clamping and conveying mechanism 2 and a discharging mechanism 3. The winding mechanism 1 is used to discharge the winding belt so that the winding belt is wound around the outside of four cables, and the four cables can form a wire harness. The discharging mechanism 3 is connected to the winding mechanism 1, and is used to clamp and convey the part after the wire harness is wound, so that the wire harness gradually passes through the winding mechanism 1, and the wire harness is gradually wound by the winding mechanism 1. The clamping and conveying mechanism 2 is connected to the winding mechanism 1, and is used to clamp the wire harness that has not passed through the winding mechanism 1, so that the wire harness located between the clamping and conveying mechanism 2 and the discharging mechanism 3 is in a straightened state, so as to avoid the cable being subjected to torsion after the winding belt generates radial tension on the cable, thereby causing the twisted cable to deviate from the original radial arrangement position, so as to facilitate the subsequent repair of a single damaged cable.

[0032] like Figure 1 and Figure 2As shown, the winding mechanism 1 includes a base plate 11, a mounting seat 12, a rotating drum 13, a reel 14, a driving source 15, a transmission wheel 16, a transmission wheel 2 17 and a driving belt 18. The mounting seat 12 is connected to the top of the base plate 11, and the mounting seat 12 is vertically arranged between the base plate 11. The rotating drum 13 is rotatably connected to the mounting seat 12. The rotating drum 13 has a central axis. The rotating drum 13 can rotate along the central axis. The wire harness can pass horizontally from the middle position of the rotating drum 13. The reel 14 is connected to the left edge of the rotating drum 13, so that when the rotating drum 13 rotates, it can drive the reel 14 to move in a circular trajectory along the central axis, so that the reel 14 can wind the winding belt On the outside of the wire harness, the winding operation of the wire harness is completed. The driving source 15 is connected to the right side of the mounting seat 12, and the transmission wheel 16 is rotatably connected to the left side of the mounting seat 12. There are two transmission wheels 16. The driving source 15 is a motor with an output shaft facing left, and the output shaft of the driving source 15 passes through the left side of the mounting seat 12. The transmission wheel 2 17 is connected to the output shaft of the driving source 15. The driving belt 18 is transmission-connected between the transmission wheel 2 17 and the two transmission wheels 16, and the driving belt 18 is in close contact with the rotating drum 13, so that the driving belt 18 can drive the rotating drum 13 to rotate when it is running, thereby providing power for the unwinding roller 14 to move in a circular trajectory along the central axis.

[0033] Start the driving source 15 to drive the driving belt 18, the transmission wheel 2 17 and the two transmission wheels 1 16, and the driving belt 18 drives the rotating drum 13 to rotate along the central axis. At this time, the wire harness passes through the clamping transmission of the clamping conveying mechanism 2 and the discharging mechanism 3 so that the wire harness passes horizontally along the central axis of the rotating drum 13, and the wire harness between the clamping conveying mechanism 2 and the discharging mechanism 3 is in a straight state. When the rotating drum 13 rotates, it drives the unwinding roller 14 to move in a circular trajectory along the central axis, so that the winding belt is wound around the outside of the wire harness between the clamping conveying mechanism 2 and the discharging mechanism 3.

[0034] like Figures 1 to 6As shown, the clamping and conveying mechanism 2 includes a mounting cylinder 21, a mounting roller 22, a guide frame 23, a clamping and conveying member 24, a transmission member 25, a gear ring 26 and a gear 27. The mounting cylinder 21 is arranged on the right side of the mounting seat 12, and the mounting cylinder 21 is coaxially arranged with the rotating cylinder 13. The mounting roller 22 is connected to the right edge of the mounting cylinder 21, and the guide frame 23 is connected to the inner right end of the mounting cylinder 21. There are four mounting rollers 22, and cables are wound around the outer sides of the four mounting rollers 22. The cables on the four mounting rollers 22 pass through the guide frame 23. The four cables can be guided by the guide frame 23 so that the four cables are parallel to the central axis, thereby forming a wiring harness, so that the wiring harness can be subsequently conveyed to the winding mechanism 1 for winding. The clamping and conveying member 24 is connected in the mounting cylinder 21, and the clamping and conveying member 24 can clamp and convey the wiring harness so that the wiring harness between the clamping and conveying member 24 and the discharging mechanism 3 is in a straightened state, so that the winding belt can be wound around the wiring harness.

[0035] The transmission member 25 is connected between the mounting cylinder 21 and the mounting seat 12. The transmission member 25 includes a driving source three 251, a gear two 252 and a gear ring two 253. The gear ring two 253 is connected to the outside of the mounting cylinder 21. The driving source three 251 is connected to the right side of the mounting seat 12. The driving source three 251 is a motor. The gear two 252 is connected to the output shaft of the driving source three 251. The gear two 252 is meshed with the gear ring two 253. The gear ring one 26 is connected to the left side of the mounting seat 12. The gear one 27 is connected to the unwinding roller 14. The unwinding roller 14 is rotatably connected to the rotating drum 13. The gear ring one 26 is meshed with the gear one 27. The driving source three 251 is started to drive the gear two 252 and the gear ring two 253 to mesh and transmit. The gear ring two 253 drives the mounting cylinder 21 to rotate, and the rotation direction of the mounting cylinder 21 is opposite to the rotation direction of the rotating drum 13. At the same time, the discharging mechanism 3 can rotate synchronously with the mounting cylinder 21 to make the wiring harness rotate. When being wound by the winding belt, it can rotate along the central axis, and the rotation direction of the wire harness is opposite to the direction in which the unwinding roller 14 moves in a circular trajectory along the central axis. When the unwinding roller 14 moves along the circular trajectory, the gear 27 and the gear ring 26 are meshed for transmission, so that the unwinding roller 14 rotates, and the rotation direction of the unwinding roller 14 is the same as the rotation direction of the rotating drum 13 along the central axis, so as to speed up the unwinding speed of the winding belt by the unwinding roller 14. At this time, the rotating wire harness can actively wind the winding belt, and cooperate with the unwinding roller 14 to rotate in a circular trajectory along the central axis to wind the winding belt around the wire harness. Under the condition of the same winding speed of the wire harness, the speed at which the rotating drum 13 drives the unwinding roller 14 to move in a circular trajectory along the central axis can be reduced, thereby reducing the radial tension of the winding belt on the wire harness, and further preventing the cable from being separated from the original radial arrangement position after being subjected to torque, so as to facilitate the subsequent repair of the damaged cable.

[0036] Continue to refer Figures 1 to 6As shown, the clamping conveyor 24 includes a mounting frame 241, a chain / belt transmission structure, a pushing structure and a clamping member 246. The clamping member 246 is provided with six groups, and the number of clamping members 246 in each group is set to two, which is used to clamp the wire harness. The mounting frame 241 and the chain / belt transmission structure are provided with two, and are symmetrically distributed about the central axis. The two chain / belt transmission structures are respectively connected to the two mounting frames 241, and the transmission directions of the two chain / belt transmission structures are opposite. The mounting frame 241 is connected to the mounting cylinder 21. The chain / belt transmission structure includes a driving source 242, a transmission roller 243 and a transmission part. 244, two transmission rollers 243 are provided, and the two transmission rollers 243 are both rotatably connected to the inner side of the mounting frame 241, and two transmission parts 244 are provided, and the two transmission parts 244 are both transmission-connected between the two transmission rollers 243, and the two transmission parts 244 are arranged front to back, and a second driving source 242 is connected to the mounting frame 241, and the second driving source 242 is a motor, and the output shaft of the second driving source 242 is connected to one of the transmission rollers 243, and starting the second driving source 242 can drive the two transmission parts 244 and the two transmission rollers 243 to transmit, and the two transmission parts 244 transmit synchronously in the same direction.

[0037] The pushing structure is connected between the two chain / belt transmission structures, and the pushing structure includes a moving part 245, an elastic part 247, a blocking part 248 and a guiding part 249. The moving part 245 and the elastic part 247 are both arranged in six groups, and the number of each group of the moving part 245 and the elastic part 247 is both arranged in two. The six groups of elastic parts 247 are respectively connected to the six groups of moving parts 245, and the two moving parts 245 in the same group are respectively connected to the transmission parts 244 of the two chain / belt transmission structures. The two clamping members 246 in the same group are respectively plugged into the two moving parts 245 in the same group and connected to the elastic part 247. The elastic part 247 can be a spring or an elastic sheet. The blocking part 248 and the guiding part 249 are both arranged in two. The two blocking parts 248 are respectively connected to one end of the inner side of the two mounting frames 241 close to the central axis, and the two guiding parts 249 are connected to the inner side of the two mounting frames 241. On the inner side, the guide part 249 has an inclined section and a horizontal section. When two clamping members 246 of the same group pass through the two guide parts 249, the side of the moving part 245 plugged with the clamping members 246 of this group close to the center axis contacts the blocking part 248, thereby blocking the moving part 245. When the end of the clamping member 246 away from the center axis contacts the inclined section of the guide part 249, under the guidance of the inclined section, the two clamping members 246 of the same group approach each other and compress the elastic part 247 until the two clamping members 246 of the same group clamp the wire harness. After the end of the clamping member 246 away from the wire harness moves to the horizontal section, at least two groups of clamping members 246 maintain the state of clamping the wire harness, thereby clamping and conveying the wire harness. After the clamping member 246 is separated from the horizontal section, the clamping member 246 is reset under the push of the elastic part 247 to separate the clamping member 246 from the wire harness.

[0038] Four cables are respectively wound on four installation rollers 22, and one end of each of the four cables passes through the guide frame 23 and is clamped by two groups of clamping members 246 to form a wire harness. After the end of the wire harness is wound by the winding belt, it is clamped and driven by the discharging mechanism 3, and the two chain / belt transmission structures are started to run in reverse to drive the pushing structure and the six groups of clamping members 246 to move. When the two clamping members 246 of the same group pass through the two guide parts 249, the side of the moving part 245 plugged with the group of clamping members 246 close to the central axis contacts the blocking part 248, thereby blocking the moving part 245. When the end of the clamping member 246 away from the central axis contacts the inclined section of the guide part 249, the moving part 245 is blocked by the blocking part 248. , under the guidance of the inclined section, the two clamping members 246 of the same group are brought close to each other and the elastic part 247 is compressed until the two clamping members 246 of the same group clamp the wire harness. At this time, the end of the clamping member 246 away from the central axis moves to the horizontal section, and at least two groups of clamping members 246 clamp the wire harness, thereby clamping and conveying the wire harness. After the clamping member 246 is separated from the horizontal section, the clamping member 246 is reset under the push of the elastic part 247 to separate the clamping member 246 from the wire harness, thereby making the wire harness between the clamping and conveying mechanism 2 and the discharging mechanism 3 in a stretched state, and the winding mechanism 1 winds the winding belt around the outside of the stretched wire harness.

[0039] like Figure 1 , Figure 7 and Figure 8 As shown, the discharging mechanism 3 includes a support frame 31, a support cylinder 32, a connecting portion 33, two clamping rollers, a driving source four 36, a gear ring three 37, a driving source five 38 and a gear three 39. The support frame 31 is connected to the top of the bottom plate 11, the support cylinder 32 is installed on the support frame 31, the support cylinder 32 and the rotating cylinder 13 are coaxially arranged, the connecting portion 33 is connected to the inner side of the support cylinder 32, and a clamping space for radially clamping the wire harness is reserved between the two clamping rollers. The two clamping rollers are respectively an active roller 34 and a driven roller 35. The active roller 34 and the driven roller 35 are both rotatably connected to the front side of the connecting portion 33, and the active roller 34 is located at the driven roller. Above the roller 35, a driving source four 36 is connected to the rear side of the connecting part 33. The driving source four 36 is a motor. The output shaft of the driving source four 36 is connected to the active roller 34. The end of the wire harness after being wound by the winding belt is transmitted between the active roller 34 and the driven roller 35. The end of the wire harness is clamped by the active roller 34 and the driven roller 35 to make the wire harness between the clamping conveying mechanism 2 and the discharging mechanism 3 in a straight state. Starting the driving source four 36 can drive the active roller 34, so that the end of the wire harness moves along the extension line of the central axis in the direction away from the winding mechanism 1 under the drive of the active roller 34, and at the same time drives the driven roller 35 to rotate.

[0040] Gear ring three 37 is connected to the outside of the support cylinder 32, and driving source five 38 is connected to the support frame 31. Driving source five 38 is a motor, and gear three 39 is connected to the output shaft of driving source five 38. Gear three 39 is meshingly connected with gear ring three 37. Starting driving source five 38 drives gear three 39 and gear ring three 37 to mesh and transmit, thereby driving the supporting cylinder 32 and the mounting cylinder 21 to rotate synchronously in the same direction, so that the clamping conveying mechanism 2 and the discharging mechanism 3 can drive the wire harness to rotate during the conveying process of the wire harness, and the rotation direction is opposite to the direction of the circular movement of the unwinding roller 14 along the central axis. Therefore, under the condition of the same winding speed of the wire harness, the speed at which the rotating drum 13 drives the unwinding roller 14 to move in a circular trajectory along the central axis can be reduced, thereby reducing the radial tension of the winding belt on the four cables.

[0041] Working principle:

[0042] The cables on the four mounting rollers 22 are pulled so that one end of each of the four cables passes through the guide frame 23 and is clamped by two sets of clamping members 246 to form a wiring harness. After the ends of the wiring harness are wound with a winding belt, they are clamped and driven by two clamping rollers on the discharging mechanism 3.

[0043] The two groups of chain / belt transmission structures are started to run in reverse to drive the push structure and the six groups of clamping members 246 to move. When the two clamping members 246 of the same group pass through the two guide parts 249, the side of the moving part 245 plugged with the group of clamping members 246 close to the central axis contacts the blocking part 248, thereby blocking the moving part 245. When the end of the clamping member 246 away from the central axis contacts the inclined section of the guide part 249, under the guidance of the inclined section, the two clamping members 246 of the same group are brought close to each other and the elastic part 247 is compressed until Until two clamping members 246 of the same group clamp the wire harness, at this time the clamping member 246 moves away from one end of the wire harness to the horizontal section, and at least two groups of clamping members 246 clamp the wire harness, thereby clamping and conveying the wire harness. After the clamping member 246 is separated from the horizontal section, the clamping member 246 is reset under the push of the elastic part 247 to separate the clamping member 246 from the wire harness, so that the wire harness between the clamping and conveying mechanism 2 and the discharging mechanism 3 is in a straightened state, and the winding mechanism 1 wraps the winding belt around the outside of the wire harness in the straightened state.

[0044] Starting the driving source 4 36 can drive the active roller 34, so that the ends of the four cables move in a direction away from the winding mechanism 1 under the drive of the active roller 34, and at the same time drive the driven roller 35 to rotate.

[0045] The driving source 15 is started to drive the driving belt 18, the transmission wheel 2 17 and the two transmission wheels 1 16, and the driving belt 18 drives the rotating drum 13 to rotate. When the rotating drum 13 rotates, it drives the unwinding roller 14 to move in a circular trajectory along the central axis, so that the winding belt is wound around the outside of the wire harness in a straight state between the clamping conveying mechanism 2 and the discharging mechanism 3.

[0046] When the unwinding roller 14 moves in a circular trajectory along the central axis, the gear 27 and the gear ring 26 mesh and transmit, so that the unwinding roller 14 rotates, and the rotation direction of the unwinding roller 14 is the same as the rotation direction of the rotating drum 13 along the central axis, so as to speed up the unwinding speed of the unwinding roller 14 for the winding tape.

[0047] The driving source three 251 is started to drive the gear two 252 and the gear ring two 253 to engage in transmission, and the gear ring two 253 drives the installation cylinder 21 to rotate, and the rotation direction of the installation cylinder 21 is opposite to the rotation direction of the rotating drum 13. At the same time, the driving source five 38 is started to drive the gear three 39 and the gear ring three 37 to engage in transmission, thereby driving the support cylinder 32 and the installation cylinder 21 to rotate synchronously in the same direction, so that the clamping conveying mechanism 2 and the discharging mechanism 3 drive the wire harness to rotate during the process of conveying the wire harness, and the rotation direction is opposite to the direction in which the unwinding roller 14 moves in a circular trajectory along the central axis, so that the wire harness actively wraps the winding belt around the outside, thereby reducing the speed at which the rotating drum 13 drives the unwinding roller 14 to move in a circular trajectory along the central axis when the winding speed of the wire harness is the same, thereby reducing the radial tension of the winding belt on the four cables.
