Description

Technical Field

[0001] This invention belongs to the field of wire harness fixing technology, specifically referring to a robot wire harness fixing device. Background Technology

[0002] In the field of robotics, the structure of the fixing bracket for robot wiring harnesses is relatively simple, generally using cable ties, buckles, and clips, and their function is relatively singular. However, for some robot components with moving functions, such as robotic arms and robotic grippers, after the two ends of the wiring harness are fixed, it is necessary to leave room for joint movement; otherwise, it will affect joint movement and signal transmission. When the room for movement is too large, the wiring harness that needs to move cannot be fixed, and it will be loosely stored inside the robot, resulting in messy wiring, occupying a lot of space, and the wiring harness is particularly prone to getting caught on other components. When the room for movement is too small, the movement of the moving joints will pull on the wiring harness, causing damage. When maintenance is required, all the wiring harnesses are bundled together, making it impossible to distinguish them and making it difficult to repair or replace faulty lines.

[0003] Therefore, a robot harness fixing device is needed to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a robot wire harness fixing device. When the two wire harness guide heads are in the binding cylinder, they can drive the wire harness to twist at a certain angle, which can ensure that the wire harness is in a straight state and also ensure that the wire harness has a certain amount of reserved slack. When the two wire harness guide heads are pulled out from the binding cylinder, it is convenient for the installation, disassembly and maintenance of the wire harness.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a robot wire harness fixing device, including a binding cylinder. The inner wall of the binding cylinder is symmetrically provided with retaining rings. A buffer connection mechanism is provided through the binding cylinder. The buffer connection mechanism consists of two buffer support components and a torsion component. The torsion component connects the two buffer support components together. Wire harness guiding components are respectively provided at both ends of the binding cylinder. Each wire harness guiding component consists of a wire harness guiding head and a sleeve. The wire harness guiding head is a hollow cylinder and is rotatably disposed within the sleeve. The sleeve is divided into multiple shells. The wire harness guiding head is divided into multiple wire harness guiding blocks. The wire harness guiding blocks are fan-shaped with the same shape. The wire harness guiding blocks are divided into multiple concentric fan-shaped wire harness placement blocks. Each wire harness placement block has equally spaced wire grooves on its outer wall. An automatic opening component is provided in the hollow part of the wire harness guiding head. The automatic opening component is disposed on the buffer support components and the innermost wire harness placement block.

[0006] Furthermore, the inner edges of both end faces of the housing and each of the wire harness placement blocks (excluding the innermost layer) are provided with limiting grooves, and each limiting groove is arranged in a concentric arc shape. The outer edges of both end faces of each wire harness placement block are provided with limiting plates, which are located between the wire grooves. The end of the limiting plate on the end face of the outermost wire harness placement block is located in the limiting groove on the end face of the housing, and the end of the limiting plate on the end face of the wire harness placement blocks of the remaining layers is located in the limiting groove on the end face of the wire harness placement block of the layer above it.

[0007] Furthermore, the buffer support assembly includes a central cylinder, a sliding shaft, and a spring. The central cylinder is located on the center line of the restraint cylinder. The central cylinder is a cylinder with one end open. One end of the sliding shaft is slidably disposed inside the central cylinder. The spring is disposed inside the central cylinder, with its two ends respectively disposed on the inner bottom wall of the central cylinder and the inner end of the sliding shaft.

[0008] Furthermore, the automatic opening assembly includes a sliding ring, a second spring, a first swing arm, a second swing arm, a connecting block, and a baffle. The baffle is located at the outer end of the sliding shaft, the sliding ring is slidably mounted on the sliding shaft, the connecting block is fixed to the inner wall of the innermost wire harness guide head, one end of the first swing arm is hinged to the baffle, one end of the second swing arm is hinged to the sliding ring, and the other ends of the first and second swing arms are respectively hinged to the connecting block. The second spring is sleeved on the sliding shaft, with its two ends respectively located on the baffle and the sliding ring.

[0009] Furthermore, the torsion assembly includes a torsion spring and a connecting shaft. The two ends of the connecting shaft are rotatably disposed at the closed ends of the two central cylinders, and the torsion spring is sleeved on the connecting shaft. The two ends of the torsion spring are respectively disposed at the closed ends of the two central cylinders.

[0010] Furthermore, the wire groove is arranged along the axial direction of the wire harness guide head and passes through both ends of the wire harness placement block.

[0011] Furthermore, the outer wall of the binding cylinder is provided with a fixing frame.

[0012] Furthermore, the inner diameter of the retaining ring is equal to the inner diameter of the sleeve, and the outer end face of the retaining ring is provided with an array of universal balls around the axial direction.

[0013] Furthermore, each of the housings has a number on its outer wall.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. When the wire harness guide block and one end of the housing are inserted into the binding cylinder, the two wire harness guide components drive the wire harness to twist at an angle. When the robot's movable joint pulls the wire harness, the wire harness drives the wire harness guide components to rotate at an angle, which can ensure that the wire harness is in a straight state and also ensure that the wire harness has a certain amount of reserved slack. 2. When the wire harness guide block and the housing are pulled out of the binding cylinder, the sleeve is no longer bound by the binding cylinder. Spring 2 pulls the sliding ring toward the baffle side. The sliding ring drives the swing arm 2 and the swing arm 1 to rotate. The connecting block pushes the wire harness guide block outward. The adjacent wire harness guide blocks separate. Except for the innermost wire harness placement block, each layer of wire harness placement block and housing can slide, which is convenient for installing and fixing the wire harness or disassembling and repairing the wire harness.

Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1-6 As shown, this invention proposes a robot wire harness fixing device, including a binding cylinder 1. The inner wall of the binding cylinder 1 is symmetrically provided with retaining rings 2. A buffer connecting mechanism 3 is provided through the binding cylinder 1. The buffer connecting mechanism 3 consists of two buffer support components 4 and a torsion component 5. The torsion component 5 connects the two buffer support components 4 together. Wire harness guiding components 6 are respectively provided at both ends of the binding cylinder 1. The wire harness guiding component 6 consists of a wire harness guiding head 7 and a sleeve 8. The wire harness guiding head 7 is a hollow cylinder. The wire harness guide head 7 is rotatably disposed inside the sleeve 8. The sleeve 8 is divided into multiple housings 9. The wire harness guide head 7 is divided into multiple wire harness guide blocks 10. The wire harness guide blocks 10 are fan-shaped with the same shape. The wire harness guide blocks 10 are divided into multiple concentric fan-shaped wire harness placement blocks 11. Each wire harness placement block 11 has wire grooves 12 at equal intervals on its outer wall. The hollow part of the wire harness guide head 7 is provided with an automatic opening component 13. The automatic opening component 13 is disposed on the buffer support component 4 and the innermost wire harness placement block 11.

[0021] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the inner edges of both end faces of the housing 9 and each of the wire harness placement blocks 11 (excluding the innermost layer) are provided with limiting grooves 14. Each limiting groove 14 is arranged in a concentric arc shape. The outer edges of both end faces of each wire harness placement block 11 are provided with limiting plates 15. The limiting plates 15 are located between the wire grooves 12. The end of the limiting plate 15 on the end face of the outermost wire harness placement block 11 is located in the limiting groove 14 on the end face of the housing 9. The end of the limiting plate 15 on the end face of the remaining wire harness placement blocks 11 is located in the limiting groove 14 on the end face of the wire harness placement block 11 above it. There is a certain frictional resistance between the limiting plate 15 and the limiting groove 14, so that the wire harness placement blocks 11 can maintain any angular position.

[0022] like Figure 3 , Figure 7 and Figure 8 As shown, the buffer support assembly 4 includes a central cylinder 16, a sliding shaft 17, and a spring 18. The central cylinder 16 is located on the center line of the restraint cylinder 1. The central cylinder 16 is a cylinder with one end open. One end of the sliding shaft 17 is slidably disposed inside the central cylinder 16. The spring 18 is disposed inside the central cylinder 16, with its two ends respectively disposed on the inner bottom wall of the central cylinder 16 and the inner end of the sliding shaft 17. In the initial state, the spring 18 is in a tensioned state.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the automatic spreading assembly 13 includes a sliding ring 19, a second spring 20, a first swing arm 21, a second swing arm 22, a connecting block 23, and a baffle 24. The baffle 24 is located at the outer end of the sliding shaft 17. The sliding ring 19 is slidably mounted on the sliding shaft 17. The connecting block 23 is fixed to the inner wall of the innermost wire harness placement block 11. One end of the first swing arm 21 is hinged to the baffle 24. One end of the second swing arm 22 is hinged to the sliding ring 19. The other ends of the first swing arm 21 and the second swing arm 22 are respectively hinged to the connecting block 23. The second spring 20 is sleeved on the sliding shaft 17, with its two ends respectively located on the baffle 24 and the sliding ring 19. When the wire harness guide assembly 6 is inside the binding cylinder 1, the second spring 20 is in a stretched state.

[0024] like Figure 3 , Figure 7 and Figure 8 As shown, the torsion assembly 5 includes a torsion spring 25 and a connecting shaft 26. The two ends of the connecting shaft 26 are respectively rotatably disposed at the closed ends of the two central cylinders 16. The torsion spring 25 is sleeved on the connecting shaft 26, and the two ends of the torsion spring 25 are respectively disposed at the closed ends of the two central cylinders 16.

[0025] like Figure 5 and Figure 6 As shown, the wire groove 12 is arranged along the axial direction of the wire harness guide head 7 and passes through both ends of the wire harness placement block 11, and the robot wire harness 30 passes through the wire groove 12.

[0026] like Figure 1 and Figure 2 As shown, the inner diameter of the retaining ring 2 is equal to the inner diameter of the sleeve 8. The outer end face of the retaining ring 2 is provided with universal ball bearings 28 arranged around the axis. The two wire harness guide components 6 are pressed at both ends of the restraint cylinder 1. When the wire harness is pulled by the robot's movable joint, the two wire harness guide components 6 can rotate freely inside the restraint cylinder 1.

[0027] like Figure 1 and Figure 2 As shown, the outer side wall of the binding cylinder 1 is provided with a fixing frame 27.

[0028] like Figure 1 , Figure 4 and Figure 9 As shown, each of the housings 9 has a number 29 on its outer wall. In the initial state, under the action of the torsion assembly 5, the two buffer support assemblies 4 are offset by a certain angle, so that the two housings 9 with the same number 29 are offset by a certain angle.

[0029] In practical use, when it is necessary to pass the wire harness 30 through the wire harness guide head 7, the wire harness guide assembly 6 is pulled out from the binding cylinder 1. The automatic opening assembly 13 and the wire harness guide assembly 6 are pulled out together as a whole. At this time, the sleeve 8 is no longer bound by the binding cylinder 1. The second spring 20 pulls the sliding ring 19 toward the baffle 24. The sliding ring 19 drives the second swing arm 22 and the first swing arm 21 to rotate. The included angle between the first swing arm 21 and the second swing arm 22 decreases, which pushes the connecting block 23 outward. The connecting block 23 pushes the wire harness placement block 11 outward. All the wire harness placement blocks 11 are in the open state. Except for the innermost wire harness placement block 11, the wire harnesses of each layer are open. The placement block 11 and the housing 9 are slidable, so that the wire groove 12 on the wire harness placement block 11 corresponding to the number 29 can be exposed. Place the wire harness 30 in the wire groove 12 and remember the position of the wire groove 12 on the wire harness placement block 11. Then pass the wire harness 30 through the binding tube 1 and place the wire harness 30 in the wire groove 12 on the wire harness placement block 11 with the same number 29. The position of this wire groove 12 on this wire harness placement block 11 is the same as the position of the wire groove 12 on the previous wire harness placement block 11. Repeat the above operation to complete the placement of all wire harnesses 30 in the wire groove 12. The above process also facilitates the disassembly and maintenance of the wire harness 30. Then, each wire harness guide block 10 and housing 9 is pressed inward, and the wire harness placement block 11 presses the connecting block 23 inward. The connecting block 23 drives the first swing arm 21 and the second swing arm 22 to rotate. The second swing arm 22 pushes the sliding ring 19 to move, the sliding ring 19 stretches the second spring 20, and the first spring 18 pulls the sliding shaft 17 back. The sliding shaft 17 drives the baffle 24 to move, and the baffle 24 drives the first swing arm 21, the second swing arm 22, and the connecting block 23 to move. The connecting block 23 drives one end of the wire harness guide block 10 and housing 9 into the binding cylinder 1. At this time, the two wire harness guide assemblies 6 drive the wire harness 30 to rotate at an angle, which can be referred to Figure 9 and Figure 10 When the robot's movable joints pull on the wire harness 30, the wire harness 30 drives the wire harness guide assembly 6 to rotate at an angle, which can ensure that the wire harness 30 is in a straight state and also ensure that the wire harness 30 has a certain amount of reserved slack.
