DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] See also Figure 1 to Figure 5 , an automatic wrapping device for automobile wiring harnesses, comprising:

[0034] A wrapping machine body 1, on which a wrapping film 11 is installed;

[0035] The tape wrapping unit 2 is rotatably connected to the tape wrapping machine body 1, and is slidably connected to the mounting unit 3 inside. The tape wrapping unit 2 is connected to the winding film 11 through the mounting unit 3, and is used to cooperate with the mounting unit 3 to realize automatic tape wrapping of the winding film 11 on the automobile wiring harness;

[0036] The reinforcement unit 4 is rotatably connected to the end of the mounting unit 3 and is used to limit and reinforce the end of the wrapping film 11;

[0037] The rotating unit 5 is slidably connected to the inside of the wrapping unit 2, and the ends thereof are respectively connected to the mounting unit 3 and the reinforcement unit 4, and is used to drive the mounting unit 3 to slide in the wrapping unit 2 and drive the reinforcement unit 4 to rotate at the end of the wrapping unit 2;

[0038] A guide unit 6 is rotatably connected to the tape wrapping machine body 1 and is rollingly connected to the surface of the automobile wiring harness to guide the automobile wiring harness;

[0039] A traction unit 7 is rotatably connected to the tape wrapping machine body 1 and is rollingly connected to the surface of the automobile wiring harness. The end of the traction unit 7 is connected to a driving unit 8 for cooperating with the driving unit 8 to achieve traction of the automobile wiring harness.

[0040] The adjusting unit 9 is slidably connected in the traction unit 7 and is used for adjusting the clamping force of the traction unit 7 on the automobile wiring harness.

[0041] In one embodiment of the present invention, when wrapping the automobile wiring harness, the wrapping film 11 is placed on the wrapping unit 2 through the installation unit 3, and the wrapping unit 2 is turned on. The wrapping unit 2 can drive the wrapping film 11 to rotate with the cooperation of the installation unit 3, so that the wrapping film 11 can wrap the automobile wiring harness. The driving unit 8 is turned on, and the traction unit 7 can drive the automobile wiring harness to perform traction transmission with the cooperation of the driving unit 8, so that the wrapping unit 2 can continuously wrap the automobile wiring harness.

[0042] The tape wrapping unit 2 can drive the rotating unit 5 to rotate synchronously when rotating, and the rotating unit 5 will slide under the centrifugal force generated by the rotation of the tape wrapping unit 2, so that the installation unit 3 and the reinforcement unit 4 will expand and rotate in the opposite direction respectively under the action of the rotating unit 5, so that the installation unit 3 and the reinforcement unit 4 can respectively be in close contact with the inner wall and the end of the sleeve where the wrapping film 11 is located, thereby realizing automatic fixation of the wrapping film 11 and improving the stability of the wrapping film 11 when wrapping the automotive wiring harness.

[0043] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the winding unit 2 includes:

[0044] The bracket 21 is fixed on the belt wrapping machine body 1. The bracket 21 is divided into two groups, and two groups of driving shafts 22 are rotatably connected to the two groups of brackets 21.

[0045] The driving member 23 is installed on the side of the bracket 21, wherein the end of one group of the driving shafts 22 is connected to the output end of the driving member 23, and the ends of any two adjacent groups of driving shafts 22 are connected by a transmission belt 25;

[0046] The driving wheels 24 are mounted on the end surfaces of the four sets of driving shafts 22, and the four sets of driving wheels 24 are rollingly connected to the surface of the belt ring 26;

[0047] The opening 261 is formed on the belt ring 26 .

[0048] In this embodiment, when the automobile wiring harness is taped, the automobile wiring harness is passed through the opening 261 into the taping ring 26, the wrapping film 11 (or the wrapping tape) is placed on the taping ring 26 through the mounting unit 3, and one end of the wrapping film 11 is fixed to the surface of the automobile wiring harness.

[0049] The driving member 23 is turned on, and the output end of the driving member 23 can drive the driving shaft 22 to rotate on the bracket 21. Since the ends of any two adjacent groups of driving shafts 22 are connected by the transmission belt 25, the four groups of driving shafts 22 will rotate under the drive of the four groups of transmission belts 25. When the four groups of driving shafts 22 rotate, they can drive the driving wheels 24 on their surfaces to rotate synchronously. Since the surface of the belt wrapping ring 26 is rollingly connected to the four groups of driving wheels 24, the belt wrapping ring 26 will rotate under the action of the four groups of driving wheels 24. When the belt wrapping ring 26 rotates, it can drive the winding film 11 to rotate synchronously through the installation unit 3, so that the winding film 11 can wrap the surface of the automobile wiring harness.

[0050] Furthermore, the installation unit 3 and the wrapping film 11 (wrapping tape) may be installed in two groups, and the surface of the automobile wiring harness may be wrapped with two groups of wrapping films 11 (wrapping tapes) or with the wrapping film 11 and the wrapping tape alternately.

[0051] In one embodiment of the present invention, Figure 4 As shown, the installation unit 3 includes:

[0052] The expansion roller 31 has its end fixed on the belt ring 26 and has a through hole 32 formed inside;

[0053] The elastic airbag 33 is slidably connected in the inflation roller 31 , and its end is communicated with the through hole 32 .

[0054] In this embodiment, when installing the wrapping film 11 (or wrapping tape), the sleeve where the wrapping film 11 is located is placed on the surface of the inflation roller 31. When the wrapping tape ring 26 rotates, the wrapping film 11 on its surface can be driven to rotate by the inflation roller 31, and the elastic airbags 33 will automatically expand under the action of the rotating unit 5, so that multiple groups of elastic airbags 33 are in close contact with the inner wall of the sleeve of the wrapping film 11, thereby realizing automatic fixation of the wrapping film 11.

[0055] In one embodiment of the present invention, Figure 4 As shown, the reinforcement unit 4 includes:

[0056] The groove 41 is provided at the end of the inflation roller 31 and communicates with the through hole 32. Two sets of rotating shafts 42 are rotatably connected inside the groove 41.

[0057] A gear 43 is mounted on the two sets of rotating shafts 42, and a reinforcement frame 44 is fixed on the gear 43;

[0058] The rack 45 is slidably connected in the groove 41 and meshedly connected with the two sets of gears 43 on both sides.

[0059] In this embodiment, when the belt ring 26 drives the wrapping film 11 to rotate through the expansion roller 31, the rack 45 will slide in the groove 41 in the direction away from the belt ring 26 under the action of the rotating unit 5. When sliding, the rack 45 can drive the two sets of rotating shafts 42 to rotate in the opposite direction in the groove 41 through the two sets of gears 43. At the same time, the two sets of gears 43 will drive the reinforcement frame 44 to rotate in the opposite direction, so that the two sets of reinforcement frames 44 move away from each other until the two sets of reinforcement frames 44 rotate to the same straight line. At this time, the two sets of reinforcement frames 44 will both contact the end of the sleeve where the wrapping film 11 is located, thereby preventing the sleeve where the wrapping film 11 is located from slipping out of the surface of the expansion roller 31, thereby improving the stability of the wrapping film 11 installed on the surface of the expansion roller 31.

[0060] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the rotating unit 5 comprises:

[0061] A slide groove 51 is provided inside the belt wrap ring 26. The slide groove 51 is at least eight groups, and a first sliding plug 52 is slidably connected inside the slide groove 51.

[0062] The connecting empty pipe 53 is provided inside the belt ring 26, one end of which is connected to each group of slide grooves 51, and the other end of which is connected to the through hole 32;

[0063] The second sliding plug 54 is slidably connected inside the through hole 32 , and an end of the second sliding plug 54 is connected to the rack 45 .

[0064] In this embodiment, when the belt ring 26 rotates under the action of the four groups of driving wheels 24, the belt ring 26 can drive the first sliding plug 52 inside it to rotate synchronously through each group of slide grooves 51. When the rotation speed of the belt ring 26 gradually increases, each group of first sliding plugs 52 will slide in the corresponding slide groove 51 under the action of centrifugal force, so that the space in each group of slide grooves 51 will be reduced, and then the air in the slide groove 51 will enter the through hole 32 in the inflation roller 31 through the connecting empty tube 53 under the squeezing of the first sliding plug 52. Since the end of each group of elastic airbags 33 is connected to the through hole 32, each group of elastic airbags 33 will expand, so that the multiple groups of elastic airbags 33 are in close contact with the inner wall of the sleeve of the wrapping film 11, thereby realizing automatic fixation of the wrapping film 11.

[0065] When the air in each group of slide grooves 51 enters the through hole 32 through the connecting empty pipe 53, the second sliding plug 54 will slide in the direction away from the winding ring 26 under the push of the air pressure inside the through hole 32. When sliding, the second sliding plug 54 can push the rack 45 to slide synchronously in the groove 41, so that the two groups of gears 43 will drive the two groups of reinforcement frames 44 to rotate in opposite directions under the action of the rack 45 until the two groups of reinforcement frames 44 contact the end of the sleeve where the winding film 11 is located, thereby preventing the sleeve where the winding film 11 is located from slipping off the surface of the inflation roller 31, thereby improving the stability of the winding film 11 when wrapping the automobile wiring harness.

[0066] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the guide unit 6 includes:

[0067] A support frame 61 is fixed on the belt wrapping machine body 1, and two sets of rotating rods 62 are rotatably connected to the support frame 61;

[0068] The elastic guide roller 63 is installed on the surface of the rotating rod 62 .

[0069] In this embodiment, when the automobile wiring harness is wrapped, the automobile wiring harness is passed between two sets of elastic guide rollers 63. The two sets of elastic guide rollers 63 can guide the automobile wiring harness, thereby improving the stability of the automobile wiring harness when wrapped. The guide unit 6 can be installed in two sets, which is not a sole limitation here.

[0070] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the traction unit 7 includes:

[0071] The fixing frame 71 is connected to the belt wrapping machine body 1, and two sets of first support plates 711 are fixed on the side;

[0072] The first traction roller 72 has its ends rotatably connected to the two sets of first support plates 711;

[0073] The sliding frame 73 is slidably connected to the surface of the fixed frame 71, and two sets of second support plates 731 are fixed on the side;

[0074] The second traction roller 74 has its ends rotatably connected to the two sets of second support plates 731;

[0075] The clamping groove 741 is provided on the surface of the first traction roller 72 and the second traction roller 74 .

[0076] In this embodiment, three groups of clamping grooves 741 are opened on the surfaces of the first traction roller 72 and the second traction roller 74. The specifications of the three groups of clamping grooves 741 are inconsistent, so that the clamping grooves 741 can adapt to automobile wiring harnesses of different specifications.

[0077] When the automobile wiring harness is taped, the taped automobile wiring harness is passed through one group of clamping grooves 741, and the driving unit 8 is turned on. The driving unit 8 can drive the first traction roller 72 on the first support plate 711 and the second traction roller 74 on the second support plate 731 to rotate in the opposite direction, so that the first traction roller 72 and the second traction roller 74 can drive the clamping grooves 741 on their surfaces to rotate in the opposite direction, and then the clamping grooves 741 can pull and slide the taped automobile wiring harness inside, so that the taping unit 2 can continuously tap the automobile wiring harness.

[0078] In one embodiment of the present invention, Figure 1 As shown, the driving unit 8 includes:

[0079] An auxiliary bracket 81 is connected to the side of the fixing bracket 71, and a driver 83 is installed on the side;

[0080] A driving gear 82 is rotatably connected to the auxiliary bracket 81, and an end portion is connected to an output end of a driver 83;

[0081] The face gears 84 are fixed to the ends of the first traction roller 72 and the second traction roller 74 , and both sets of face gears 84 are meshedly connected with the driving gear 82 .

[0082] In this embodiment, the driver 83 is turned on, and the driver 83 can drive the driving gear 82 to rotate in the auxiliary bracket 81. The driving gear 82 can drive the first traction roller 72 on the first support plate 711 and the second traction roller 74 on the second support plate 731 to rotate in the opposite direction through the connection with the two sets of face gears 84, so that the first traction roller 72 and the second traction roller 74 can drive the clamping groove 741 to rotate in the opposite direction synchronously, and then the clamping groove 741 can pull and slide the automobile wiring harness wrapped therein, so as to facilitate the winding unit 2 to continuously wrap the automobile wiring harness.

[0083] The driving member 23 and the driver 83 may both be pneumatic motors or electric motors, which are not limited here.

[0084] In one embodiment of the present invention, Figure 5 As shown, the adjustment unit 9 includes:

[0085] An L-shaped frame 91 is connected to the end of the fixed frame 71, and a limiting frame 911 is fixed on the side thereof, and the limiting frame 911 is slidably connected in the sliding frame 73;

[0086] A sliding rod 92, one end of which is fixed to the inner wall of the L-shaped frame 91, and the other end of which is slidably connected to the inside of the sliding frame 73;

[0087] The bolt 93 is connected to the surface of the sliding rod 92 through threads, and an elastic member 94 is connected between the bolt 93 and the end of the sliding frame 73 .

[0088] In this embodiment, when the gap between the first traction roller 72 and the second traction roller 74 needs to be adjusted, the bolt 93 is rotated with a wrench so that the bolt 93 is raised and lowered on the surface of the sliding rod 92 , so that the bolt 93 can adjust the elastic force of the elastic member 94 .

[0089] When the bolt 93 slides downward on the surface of the sliding rod 92, the elastic member 94 is compressed, so that the sliding frame 73 can slide downward on the surface of the fixed frame 71 under the elastic force of the elastic member 94, so that the sliding frame 73 can drive the second traction roller 74 to slide downward through the second support plate 731, and the gap between the second traction roller 74 and the first traction roller 72 can be adjusted, and then the specification of the clamping groove 741 can be adjusted, so that the clamping groove 741 can adapt to automobile wiring harnesses of different specifications, and at the same time, the clamping force of the clamping groove 741 on the automobile wiring harness can be increased, so as to facilitate stable traction of the automobile wiring harness.

[0090] When the bolt 93 slides upward on the surface of the sliding rod 92, the working process is opposite to the above, and the gap between the second traction roller 74 and the first traction roller 72 increases, so that the clamping groove 741 can adapt to larger specifications of automobile wiring harnesses.

[0091] When the sliding frame 73 slides on the surface of the fixed frame 71, the sliding rod 92 and the limiting frame 911 can guide and limit the sliding frame 73, thereby improving the stability of the sliding frame 73 when it is lifted or lowered. The elastic member 94 can also buffer the second traction roller 74 and the clamping groove 741 through the sliding frame 73, thereby preventing the clamping groove 741 on the surface of the second traction roller 74 from having a hard mechanical collision with the surface of the automobile wiring harness, thereby improving the protective performance of the automobile wiring harness. The elastic member 94 can be a spring or elastic rubber, which is not limited here.

[0092] The working principle of the present invention is: when wrapping the automobile wiring harness, the automobile wiring harness is passed through the opening 261 into the inside of the wrapping ring 26, the wrapping film 11 is placed on the wrapping ring 26 through the installation unit 3, and one end of the wrapping film 11 is fixed on the surface of the automobile wiring harness. The driving member 23 is turned on, and the output end of the driving member 23 can drive the driving shaft 22 to rotate on the bracket 21. When the four groups of driving shafts 22 rotate, they can drive the driving wheels 24 on their surfaces to rotate synchronously. At the same time, the wrapping ring 26 will rotate under the action of the four groups of driving wheels 24. When the wrapping ring 26 rotates, it can drive the wrapping film 11 to rotate synchronously through the installation unit 3, so that the wrapping film 11 can wrap the surface of the automobile wiring harness.

[0093] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
