Description

Technical Field

[0001] The present invention belongs to the technical field of wire harness processing, and specifically relates to a charging gun wire harness cutting and stripping device. Background Technique

[0002] The wire harness is used to achieve the electrical connection between the charging gun and the charging pile. To facilitate the use of the charging gun, the wire harness of the charging gun needs to have a certain length. When processing the charging gun wire harness, a cutting and stripping device is required to cut the wire harness into a certain length and remove a part of the insulating skin at the end of the wire harness to expose the wire core for connection with the charging gun and the charging pile.

[0003] When processing the charging gun wire harness, it is necessary to convey the free end of the coiled wire harness to the cutting and stripping position through a conveying mechanism for cutting and stripping. After the wire harness is cut, the conveying mechanism outputs the cut wire harness and continues to convey the coiled wire harness for the cutting process of the next section of the wire harness. During the cutting and conveying process of the wire harness, the free end of the coiled wire harness after cutting will naturally droop downward under the action of gravity due to the lack of support force, resulting in difficulty in stably conveying the free end of the wire harness forward and affecting the smooth progress of wire harness cutting. Moreover, the existing cutting and stripping device can only strip one end of the cut wire harness at a time, resulting in low wire harness processing efficiency. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0023] Refer to Figure 1 、 Figure 2 and Figure 4 , a charging gun wire harness cutting and stripping device provided in this embodiment includes: The cutting and stripping mechanism 1 includes a set of cutting mechanisms and two sets of stripping mechanisms, and the two sets of stripping mechanisms are arranged on both sides of the cutting mechanism; The conveying mechanism 2 is symmetrically provided with two sets, and the two sets of stripping mechanisms are respectively arranged corresponding to the two sets of conveying mechanisms 2. Under the combined action of the stripping mechanism and the conveying mechanism 2, the stripping action of different lengths of the wire harness end is completed; The driving mechanism 3 is used to drive the two sets of conveying mechanisms 2 to rotate in the same or opposite directions. When the two sets of conveying mechanisms 2 rotate in the same direction, the two sets of conveying mechanisms 2 jointly complete the wire harness conveying. When the two sets of conveying mechanisms 2 rotate in opposite directions, the two sets of conveying mechanisms 2 respectively cooperate with the two sets of stripping mechanisms to strip the two ends of the wire harness; There are two wire guide cylinders 4 corresponding to the two sets of conveying mechanisms 2. The wire guide cylinders 4 are located between the wire stripping mechanism and the conveying mechanism 2. The distance between the two wire guide cylinders 4 is configured to be adjustable. After the wire harness is cut, the conveying mechanism 2 conveys the wire harness. First, control the two wire guide cylinders 4 to move towards each other. The two wire guide cylinders 4 approach each other, and the distance between them decreases. The free end of the wire harness is stably conveyed from one wire guide cylinder 4 to the other wire guide cylinder 4. Then, control the two wire guide cylinders 4 to move in opposite directions. The free end of the wire harness continues to move towards the other set of conveying mechanism 2 along with the wire guide cylinder 4. When the two wire guide cylinders 4 are respectively close to the two sets of conveying mechanisms 2, the free end of the wire harness is stably conveyed to the conveying mechanism 2 in front of the cutting and wire stripping mechanism 1 under the guidance of the wire guide cylinder 4, ensuring the stable conveyance of the wire harness.

[0024] It should be noted that in this embodiment, the wire harness in the system is conveyed from the conveying mechanism 2 behind the cutting and wire stripping mechanism 1 to the conveying mechanism 2 in front of the cutting and wire stripping mechanism 1.

[0025] Specifically, refer to Figures 5 - 7 , in this embodiment, the driving mechanism 3 includes: A driving motor 5, including an output shaft, and a driving gear 6 is fixedly arranged on the output shaft; Driving components, two sets are symmetrically arranged on both sides of the driving gear 6; The driving components include: A transmission shaft 7, and two sets of bevel gear transmission groups are arranged at both ends of the transmission shaft 7; A driven gear 8, fixedly arranged on the transmission shaft 7; Among them, the driving gear 6 is configured to be adjustable relative to the positions of the two driven gears 8, and the driving gear 6 is configured to mesh with one of the driven gears 8; For one set of driving components, the bevel gear transmission groups at both ends of the transmission shaft 7 are symmetrically arranged, and the two sets of conveying mechanisms 2 are driven to rotate in opposite directions through the two symmetrically arranged bevel gear transmission groups; For the other set of driving components, the bevel gear transmission groups at both ends of the transmission shaft 7 are arranged in an array, and the two sets of conveying mechanisms 2 are driven to rotate in the same direction through the two bevel gear transmission groups arranged in an array.

[0026] Specifically, refer to Figure 5 , in this embodiment, the driving mechanism 3 further includes a protective box 9, and the transmission shaft 7 is rotatably arranged on the side wall of the protective box 9; A position adjusting mechanism is fixedly arranged on the inner bottom wall of the protective box 9. The position adjusting mechanism includes: A first shaft seat 10, fixedly arranged on the inner bottom wall of the protective box 9; A position adjusting motor 11, fixedly arranged on the first shaft seat 10; The position adjustment screw 12 is rotatably arranged on the first shaft seat 10, and the position adjustment screw 12 is connected to the output shaft of the position adjustment motor 11; The position guiding slide bar 13 is fixedly arranged on the first shaft seat 10; The driving motor 5 is connected to the position adjustment screw 12 through a thread, and the driving motor 5 is slidably arranged on the position guiding slide bar 13.

[0027] During use, under the action of the position adjustment motor 11, the position of the driving motor 5 is adjusted, that is, the meshing state of the driving gear 6 and the two groups of driven gears 8 is adjusted; When the driving gear 6 meshes with the driven gears 8 corresponding to the two symmetrically arranged bevel gear sets, the two conveying mechanisms 2 are driven to rotate in opposite directions; When the driving gear 6 meshes with the driven gears 8 corresponding to the two bevel gear sets arranged in an array, the two conveying mechanisms 2 are driven to rotate in the same direction.

[0028] Specifically, referring to Figure 5 , in this embodiment, the bevel gear transmission group includes a driving bevel gear 14 and a driven bevel gear 15. The driving bevel gear 14 is fixedly arranged on the transmission shaft 7, the side wall of the protective box 9 is rotatably provided with a driving shaft 16, the driven bevel gear 15 is fixedly arranged on the driving shaft 16, the driving bevel gear 14 and the driven bevel gear 15 are meshed, and under the meshing action of the driving bevel gear 14 and the driven bevel gear 15, the driving shaft 16 is driven to rotate by the transmission shaft 7.

[0029] It should be noted that the symmetric arrangement described in this solution means that the driven bevel gears 15 of the two bevel gear transmission groups are respectively located on the opposite sides of the corresponding driving bevel gears 14, and the array arrangement means that the driven bevel gears 15 of the two bevel gear transmission groups are respectively located on the same side of the corresponding driving bevel gears 14. Due to the difference in the arrangement sides of the driven bevel gears 15 relative to the driving bevel gears 14, the rotation directions of the driving shafts 16 are different.

[0030] Specifically, referring to Figure 3 , in this embodiment, a spacing adjustment mechanism is provided on the bottom wall of the protective box 9; The spacing adjustment mechanism includes: The second shaft seat 17 is fixedly arranged on the bottom wall of the protective box 9; The spacing adjustment motor 18 is fixedly arranged on the second shaft seat 17; The spacing adjustment screw 19 is a bidirectional screw.

Two sets of the spacing adjustment blocks 21 are symmetrically arranged at both ends of the spacing adjustment screw 19, and the two wire guide cylinders 4 are respectively connected to the two sets of spacing adjustment blocks 21.

[0031] During operation, under the action of the spacing adjustment motor 18, the spacing between the two sets of spacing adjustment blocks 21 is driven to be adjusted.

[0032] It should be noted that in the attached drawings of this embodiment, it is shown that the spacing adjustment motor 18 is located on the side perpendicular to the spacing adjustment screw 19, and the transmission direction of the adjustment can be changed through the transmission of bevel gears, so as to ensure the stable drive of the spacing adjustment motor 18 to the spacing adjustment screw 19.

[0033] Specifically, referring to Figure 2 、 Figure 3 and Figure 7 In this embodiment, the spacing adjustment mechanism is located on one side of the cutting and stripping mechanism 1. By arranging the spacing adjustment mechanism on one side of the cutting and stripping mechanism 1, the actions between the spacing adjustment mechanism and the cutting and stripping mechanism 1 are avoided from interfering with each other; The wire guide cylinder 4 is connected to the spacing adjustment block 21 through an L-shaped mounting bracket 22. Through the setting of the L-shaped mounting bracket 22, the position of the wire guide cylinder 4 can correspond to that of the cutting and stripping mechanism 1.

[0034] Specifically, referring to Figure 1 、 Figure 2 and Figure 7 In this embodiment, the conveying mechanism 2 includes: A bracket 23, on which a protective box 9 is fixedly arranged. The bracket 23 plays a role of bearing and supporting the protective box 9; A conveying assembly, including an upper conveying assembly and a lower conveying assembly. The upper conveying assembly is located above the lower conveying assembly, and the upper conveying assembly and the lower conveying assembly cooperate to convey the wire harness; The conveying assembly includes a fixing plate 24, a conveying shaft 25 and a conveyor belt 26. The fixing plate 24 is fixedly connected to the bracket 23. A plurality of groups of the conveying shafts 25 are rotatably arranged on the fixing plate 24, and the conveyor belt 26 is sleeved on the conveying shafts 25. The cooperation of the plurality of groups of conveying shafts 25 ensures that the conveyor belt 26 rotates stably in a tensioned state, and the wire harness is conveyed through the cooperation of the upper conveying assembly and the lower conveying assembly.

[0035] Specifically, referring to Figure 7 In this embodiment, an auxiliary roller shaft 27 is rotatably arranged on the fixing plate 24. The auxiliary roller shaft 27 is in contact with the conveyor belt 26. Through the setting of the auxiliary roller shaft 27, the lower surface of the upper conveying assembly and the upper surface of the lower conveying assembly are ensured to be in a horizontal state, and the clamping and conveying stability of the conveyor belt 26 for the wire harness is ensured.

[0036] Specifically, referring toFigure 1 , Figure 2 and Figure 4 , in this embodiment, there are two sets of drive shafts 16 corresponding to the conveying mechanism 2. One set of conveying shafts 25 of the drive shaft 16 and the lower conveying assembly are connected by a synchronous belt 28. The multiple sets of conveying shafts 25 of the conveying assembly are connected by a synchronous belt 28. One set of conveying shafts 25 of the upper conveying assembly and the lower conveying assembly are connected by a synchronous belt 28. Driven by the synchronous belt 28, the drive shaft 16 drives the lower conveying assembly to rotate and work, and the lower conveying assembly drives the upper conveying assembly to rotate and work.

[0037] It should be noted that synchronous discs are fixedly provided on both the conveying shaft 25 and the drive shaft 16, and the synchronous belt 28 is sleeved on the corresponding synchronous discs to realize the driving of the upper conveying assembly and the lower conveying assembly.

[0038] Specifically, referring to Figure 4 , in this embodiment, a lifting cylinder 29 is fixedly provided at the upper end of the bracket 23. The upper conveying assembly is fixedly connected to the free end of the lifting cylinder 29. Under the action of the lifting cylinder 29, the distance between the upper conveying assembly and the lower conveying assembly is adjusted. The wire guiding cylinder 4 is detachably connected to the mounting bracket 22 by bolts. With the adjustable-height upper conveying assembly and the detachable mounting bracket 22 provided, the stable cutting and stripping requirements of wire harnesses with different diameters are met.

[0039] Specifically, referring to Figure 1 , Figure 2 and Figure 4 , in this embodiment, a tension adjusting cylinder 30 is fixedly provided at the upper end of the bracket 23. A mounting plate 31 is fixedly provided at the free end of the tension adjusting cylinder 30. A tension adjusting shaft 32 is rotatably provided on the mounting plate 31. One set of output shafts of the upper conveying assembly, the lower conveying assembly and the tension adjusting shaft 32 are connected by a synchronous belt 28. When adjusting the height of the upper conveying assembly, the positions of the conveying shafts 25 connected by the synchronous belt 28 between the upper conveying assembly and the lower conveying assembly change, and the tension of the synchronous belt 28 changes. The tension of the synchronous belt 28 can be adjusted and controlled by adjusting the position of the tension adjusting shaft 32.

[0040] Specifically, referring to Figure 1 , Figure 2 , Figure 4 and Figure 6 , in this embodiment, both the cutting mechanism and the wire stripping mechanism include a first cylinder 33 and a second cylinder 34; A first cutting knife 35 is fixedly provided at the free end of the first cylinder 33 of the cutting mechanism. A second cutting knife 35 is fixedly provided at the free end of the second cylinder 34 of the cutting mechanism. The wire harness is cut under the combined action of the first cutting knife 35 and the second cutting knife 35; The free end of the first cylinder 33 of the wire stripping mechanism is fixedly provided with a first wire stripping knife 36, and the free end of the second cylinder 34 of the wire stripping mechanism is fixedly provided with a second wire stripping knife 36. The wire harness is cut under the combined action of the first wire stripping knife 36 and the second wire stripping knife 36, and the two ends of the wire harness are wire stripped by two wire stripping mechanisms.

[0041] During operation, when the driving mechanism 3 drives the two conveying mechanisms 2 to rotate in opposite directions, it drives the free ends of the coiled wire harness and the wire harness that has been cut to move in opposite directions respectively. During the movement of the wire harness, the wire stripping of the wire harness end is completed through the cooperation of the first wire stripping knife 36 and the second wire stripping knife 36.

[0042] It should be noted that in this solution, multiple sets of cutting and wire stripping mechanisms 1 can be arranged along the width direction of the protective box 9. Cooperating with the conveying mechanism 2 with a certain width, the cutting and wire stripping of multiple wire harnesses can be carried out simultaneously.

[0043] When this equipment is in use, a wire guiding roller group needs to be arranged outside the conveying mechanism 2 behind the cutting and wire stripping mechanism 1. The free end of the coiled wire harness is guided to the conveying mechanism 2 through the wire guiding roller group. The working principle of a charging gun wire harness cutting and wire stripping equipment provided in this embodiment is as follows: (1) First, introduce the free end of the coiled wire harness between the conveyor belts 26 of the conveying mechanism 2 in front of the cutting and wire stripping mechanism 1, and pass it through the wire threading cylinder corresponding to this group of conveying mechanisms 2. Start the lifting cylinder 29 to adjust the height position of the upper conveying component, so that the distance between the upper conveying component and the lower conveying component adapts to the diameter of the wire harness, and install a wire guiding cylinder 4 on the mounting frame 22 that adapts to the diameter of the wire harness. After the height adjustment of the upper conveying component is completed, under the action of the tension adjusting cylinder 30, drive the height of the tension adjusting shaft 32 to adjust the tension of the synchronous belt 28 connecting the upper conveying component and the lower conveying component, ensuring that the lower conveying component can stably drive the upper conveying component to rotate through the synchronous belt 28.

[0044] (2) In the initial state, the driving gear 6 meshes with the driven gear 8 on the transmission shaft 7 where the conical gear transmission groups are arranged in an array. Under the action of the driving motor 5, drive the driving gear 6 to rotate. The driving gear 6 and the driven gear 8 mesh to drive this group of transmission shafts 7 to rotate. The transmission shaft 7 drives the driving conical gear 14 to rotate. The driving conical gear 14 and the driven conical gear 15 mesh to drive the driving shaft 16 to rotate. Since the conical gear transmission groups at both ends of the transmission shaft 7 are arranged in an array, that is, the driven conical gears 15 are located on the same side of the corresponding driving conical gears 14, the rotation directions of the two driving shafts 16 are the same. Under the action of the synchronous belt 28, the driving shaft 16 drives the lower conveying assembly to rotate. The lower conveying assembly drives the upper conveying assembly to rotate in the same direction. The upper conveying assembly and the lower conveying assembly cooperate to convey the wire harness forward. And the setting of the auxiliary roller shaft 27 can improve the conveying stability of the wire harness by the conveyor belt 26.

[0045] (3) During the process of the upper conveying assembly and the lower conveying assembly cooperating to convey the wire harness forward, the driving distance adjustment motor 18 rotates forward. The driving distance adjustment motor 18 drives the distance adjustment screw 19 to rotate. Through the driving of the distance adjustment screw 19 and the guiding of the distance adjustment slide rod 20, the two groups of distance adjustment blocks 21 are driven to move towards each other. The two groups of distance adjustment blocks 21 drive the two groups of wire guide cylinders 4 to approach each other through the mounting frame 22. When the two groups of wire guide cylinders 4 come into contact, the driving distance adjustment motor 18 stops rotating. Under the action of the conveying mechanism 2, the wire harness passes through one group of wire guide cylinders 4 and enters the other group of wire guide cylinders 4.

[0046] (4) The driving distance adjustment motor 18 rotates in reverse, and the two groups of wire guide cylinders 4 move away from each other. And it is necessary to ensure that the moving linear speed of the wire guide cylinders 4 is the same as the linear speed of the conveyor belt 26. Under the action of the conveying mechanism 2, the wire harness continues to be conveyed forward. When the two groups of wire guide cylinders 4 approach the two groups of conveying mechanisms 2 respectively, the two groups of wire guide cylinders 4 stop the position movement. The free end of the wire harness enters between the conveyor belts 26 of a group of conveying mechanisms 2 located in the front through the wire guide cylinders 4. Since the speeds and directions of the two groups of conveying mechanisms 2 are the same, the stable conveying of the wire harness is completed under the combined action of the two groups of conveying mechanisms 2. During the above entire conveying process, there is always a group of wire guide cylinders 4 to support the free end of the wire harness, avoiding the free end of the wire harness from drooping and affecting the stable conveying of the wire harness.

[0047] (5) When the required length of the wire harness is conveyed, the driving mechanism 3 stops working, and the driving cutting knife 35 acts to complete the cutting of the wire harness.

[0048] (6) Then the position adjustment motor 11 is started. The position adjustment motor 11 drives the position adjustment screw 12 to rotate. Under the action of the position guiding slide rod 13, the driving motor 5 is driven to move. The driving motor 5 drives the driving gear 6 to mesh with the driven gear 8 on the transmission shaft 7 provided with a symmetrical bevel gear transmission group. Since the bevel gear transmission groups at both ends of the transmission shaft 7 are symmetrically arranged, that is, the driven bevel gear 15 is located on the opposite side of the corresponding driving bevel gear 14, the rotation directions of the two groups of driving shafts 16 are opposite. The conveying mechanism 2 located in front of the cutting and wire stripping mechanism 1 drives a section of the wire harness cut off forward, and the conveying mechanism 2 located behind the cutting and wire stripping mechanism 1 drives the free end of the coiled wire harness backward. After the wire harness is conveyed a corresponding length, the wire stripping knife 36 is driven to act to complete the wire stripping operation of the wire harness. The wire stripping length is determined by the above-mentioned "corresponding length of wire harness conveyance". When the wire harness conveyance length is long, the wire stripping length is relatively short; when the wire harness conveyance length is short, the wire stripping length is relatively long.

[0049] One set of wire stripping mechanisms cooperates with the conveying mechanism 2 to complete the wire stripping of the free end of the coiled wire harness, and the other set of wire stripping mechanisms cooperates with the conveying mechanism 2 to complete the wire stripping of the other end of the wire harness after cutting. By cooperating two sets of wire stripping mechanisms with the conveying mechanism 2 in opposite movement directions, the wire stripping operations at both ends of the wire harness can be completed simultaneously, improving the wire stripping efficiency of the wire harness.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
