Description

Technical Field

[0001] This application relates to the field of power equipment manufacturing, and in particular to an automated shielding ring installation device. Background Technology

[0002] In the modern automotive industry, electronic cables are responsible for connecting and transmitting power and signals between various electronic control units, sensors, and actuators in a vehicle. Electromagnetic compatibility (EMC) design is crucial to ensure the stable and reliable operation of electronic systems in complex electromagnetic environments. Adding shielding rings to critical signals (such as radio frequency lines and high-frequency data lines) is a widely used and efficient solution. Shielding rings are typically made of high-permeability metal materials, and their function is equivalent to a common-mode choke, effectively suppressing high-frequency common-mode noise and preventing its propagation or radiation along the cable, thereby purifying and enhancing the signal.

[0003] Currently, in the installation of automotive cables, shielding rings are mostly installed manually or semi-automatically. Operators need to manually thread the cable through the shielding ring, then position and secure it. However, this method is inconvenient, as workers need to thread the shielding ring through each cable sequentially. Therefore, a shielding ring pre-installation device is designed. This device has a first gripper, a second gripper, a feeding structure, and a transfer structure. The feeding structure is used to transport the shielding ring, the first gripper is used to hold the cable, the second gripper is used to hold the shielding ring, and the transfer component is used to move the second gripper so that the shielding ring can be fitted onto the outer wall of the cable.

[0004] In this process, the cable needs to be placed on the first clamp, and then the second clamp is used to put the shielding ring on the outer wall of the cable. However, since the cable is flexible and the movement direction of the second clamp is fixed, it is difficult to put the shielding ring on its outer wall if the end of the cable falls due to its own weight. This needs to be improved. Utility Model Content

[0005] To facilitate the installation of the shielding ring on the outer wall of the cable, this application provides an automated shielding ring installation device.

[0006] The automated shielding ring installation device provided in this application adopts the following technical solution: An automated shielding ring installation device includes a frame and a first clamping assembly, a second clamping assembly, and a feeding assembly mounted on the frame. The second clamping assembly is used to clamp cables; the feeding assembly is used to feed shielding rings; the first clamping assembly includes a first thumb cylinder, two first clamping plates, and two guide plates; the frame is provided with a linear module for mounting the first thumb cylinder; the two first clamping plates and the two guide plates are respectively mounted on the two output shafts of the first thumb cylinder. The two first clamping plates are used to clamp the shielding ring. The two guide plates have half holes on their sides that are close to each other. The two half holes enclose each other to form a guide hole. The inner diameter of the guide hole on the side away from the first clamping plate is larger than the inner diameter of the guide hole on the side close to the first clamping plate, and the inner diameter of the guide hole on the side close to the first clamping plate matches the inner diameter of the shielding ring.

[0007] By adopting the above technical solution, the guide holes formed by the two guide plates in the second clamping assembly have a tapered structure. Even if the cable is slightly offset or tilted, the cable can be captured on the large inner diameter side of the guide hole, and the position can be gradually corrected by the small inner diameter side; thereby guiding the cable end into the correct position during the shielding ring sleeve process.

[0008] Optionally, the guide plate is connected to the first thumb cylinder by bolts.

[0009] By adopting the above technical solution, the guide plate is connected to the first thumb cylinder by bolts, which facilitates the installation and disassembly of the guide plate, and the guide plate can guide cables of different outer diameters.

[0010] Optionally, the movable plug of the first thumb cylinder is provided with a plug-in block, and the guide plate is provided with a plug-in groove for the plug-in block to be inserted into; the plug-in block is provided with a first magnetic sheet, and a second magnetic sheet is provided in the plug-in groove, and the first magnetic sheet and the second magnetic sheet cooperate with each other.

[0011] By adopting the above technical solution, the installation and disassembly of the guide plate are facilitated, and the guide plate can guide cables of different outer diameters.

[0012] Optionally, the second clamping assembly is movably mounted with a positioning plate for abutting against the end of the cable.

[0013] By adopting the above technical solution, the positioning plate can ensure that the end of each cable is at the same distance relative to the second clamping component, so that the moving path length of the first clamping component remains the same each time it works, and the movement path of the first clamping component is standardized.

[0014] Optionally, the second clamping assembly includes a mounting base mounted on the frame and a second thumb cylinder mounted on the upper surface of the mounting base. The second thumb cylinder is used to clamp the cable. The upper surface of the mounting base is provided with a movable groove. The positioning plate is movably mounted in the movable groove. The positioning plate and the inner wall of the movable groove are provided with springs. The elastic force of the springs is used to drive the positioning plate to move away from the mounting base.

[0015] By adopting the above technical solution, when it is necessary to fit the shielding ring onto the end of the cable, the positioning plate is pressed down to move away from the movement path of the first clamping component, so that the shielding ring can be easily fitted onto the end of the cable; and the structure is simple, avoiding the need for workers to press down the positioning plate.

[0016] Optionally, the positioning plate is provided with a guide surface for guiding itself to move toward one side of the movable groove, the guide surface being used to abut against the guide plate.

[0017] By adopting the above technical solution, when the guide plate moves forward and contacts the guide surface of the positioning plate, the guide surface guides the positioning plate to compress into the movable groove so that the shielding ring can be fitted onto the end of the cable; and the retraction action of the positioning plate is directly triggered and executed by the forward movement of the guide plate. This structure is simple and convenient for workers to process the positioning plate.

[0018] Optionally, the two movable plugs of the second thumb cylinder are provided with second clamping plates, one of which has a triangular groove and the other has a triangular protrusion for interlocking with the triangular groove.

[0019] By adopting the above technical solution, when the cable is clamped by the two second clamping plates, the cable is guided by the inner wall of the triangular groove, clamped in the middle of the second clamping plate, and there is a gap between the mounting base, which facilitates the installation of the shielding ring.

[0020] Optionally, the side of the triangular protrusion closest to the triangular groove is set as an arc surface.

[0021] By adopting the above technical solution, the cable can be protected from damage when the two second clamping plates clamp it.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The guide holes formed by the two guide plates in the second clamping assembly have a tapered structure. Even if the cable is slightly offset or tilted, the cable can be captured on the larger inner diameter side of the guide hole, and the position can be gradually corrected by the smaller inner diameter side; thereby guiding the cable end into the correct position during the installation of the shielding ring. 2. The positioning plate ensures that the end of each cable is at the same distance relative to the second clamping component, thereby keeping the movement path length of the first clamping component the same each time it works, and standardizing the movement path of the first clamping component.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] Example 1: This application discloses an automated shielding ring installation device.

[0027] Reference Figure 1 An automated shielding ring installation device includes a frame 1 and a first clamping component 2, a second clamping component 3 and a feeding component 4 installed on the frame 1. The second clamping component 3 is used to clamp the cable, the feeding component 4 is used to feed the shielding ring, and the first clamping component 2 is used to clamp the shielding ring and sleeve it on the end of the cable.

[0028] The feeding assembly 4 includes a vibrating ring and a feeding track 42. The feeding track 42 is installed on the frame 1 and can be a long and narrow channel. The shielding rings are arranged in sequence and conveyed forward in the track. The vibrating plate 41 can arrange the shielding rings in an orderly manner and convey them to the feeding track 42. Since the vibrating plate 41 is existing technology, it will not be described in detail here.

[0029] Reference Figure 2The frame 1 is equipped with a mounting bracket 11, and the mounting bracket 11 is provided with a linear module 12. The linear module 12 is used to drive the first clamping assembly 2 to move, so that the first clamping assembly 2 clamps the shielding ring and puts it on the end of the cable. The first clamping assembly 2 includes a first thumb cylinder 21, two first clamping plates 22 and two guide plates 23. The first thumb cylinder 21 is mounted on the slider of the linear module 12. The two first clamping plates 22 and the two guide plates 23 are respectively mounted on the two output shafts of the first thumb cylinder 21. The two output shafts are used to drive the two first clamping plates 22 and the two guide plates 23 to achieve opening and closing actions.

[0030] Two first clamping plates 22 are used to clamp the shielding ring. The first clamping plates 22 can be made of metal, and rubber pads can be provided on their inner sides to increase the friction with the shielding ring and prevent the shielding ring from slipping during clamping.

[0031] Simultaneously refer to Figure 3 Two guide plates 23 are provided with half holes 25 on their sides that are close to each other. The two half holes 25 together form a guide hole 26. The inner diameter of the guide hole 26 on the side away from the first clamping plate 22 is larger than the inner diameter of the guide hole 26 on the side close to the first clamping plate 22. The inner diameter of the guide hole 26 on the side close to the first clamping plate 22 is the same as the inner diameter of the shielding ring, so that the shielding ring can be fitted onto the outer wall of the cable.

[0032] Reference Figure 3 In this embodiment, the guide plate 23 is connected to the output shaft of the thumb cylinder by bolts 24; the guide plate 23 is connected to the first thumb cylinder 21 by bolts 24, which facilitates the installation and disassembly of the guide plate 23, and the structure is simple and reduces production costs.

[0033] Reference Figure 1 and Figure 4 The frame 1 is equipped with a belt conveyor mechanism 13, and multiple sets of second clamping components 3 are provided. All second clamping components 3 are installed on the belt of the belt conveyor mechanism 13. The belt conveyor mechanism 13 is used to drive each second clamping component 3 to the installation position of the shielding ring. Since the belt conveyor mechanism 13 is existing technology, it will not be described in detail here.

[0034] Reference Figure 4 The second clamping assembly 3 includes a mounting base 31 mounted on the frame 1 and a second thumb cylinder 32 mounted on the upper surface of the mounting base 31. The two output shafts of the second thumb cylinder 32 are provided with second clamping plates 33. One of the second clamping plates 33 has a triangular groove 34, and the other second clamping plate 33 has a triangular protrusion 35 for interlocking with the triangular groove 34. In other embodiments, the side of the triangular protrusion 35 near the triangular groove 34 can be set as an arc surface.

[0035] When the two second clamping plates 33 clamp the cable, the cable is guided by the inner wall of the triangular groove 34, clamped in the middle of the second clamping plates 33, and there is a gap between them and the mounting base 31, which facilitates the installation of the shielding ring; and the arc surface can prevent the cable from being damaged when the two second clamping plates 33 clamp the cable.

[0036] The implementation principle of Embodiment 1 of this application is as follows: First, the cable is placed on the first clamping assembly 2, which clamps and secures the cable. The feeding assembly 4 then transports the shielding ring to the designated position. The first thumb cylinder 21 of the second clamping assembly 3 drives the two first clamping plates 22 to clamp the shielding ring. Then, the linear module 12 moves the second clamping assembly 3 towards the cable. Because the guide hole 26 has a tapered structure, even if the cable is slightly offset or tilted, the large inner diameter side of the guide hole 26 can capture the cable and gradually correct its position through the small inner diameter side; thus guiding the cable end into the correct position during the installation of the shielding ring; greatly improving the installation efficiency and quality of the shielding ring and reducing the inconvenience and error of manual operation.

[0037] Example 2: This application discloses an automated shielding ring installation device.

[0038] Reference Figure 5 The difference between Embodiment 2 and Embodiment 1 of this application is that: the output shaft of the first thumb cylinder 21 is provided with a plug-in block 27, and the guide plate 23 is provided with a plug-in groove 28 for the plug-in block 27 to be plugged in; the plug-in block 27 is provided with a first magnetic sheet, and a second magnetic sheet is provided in the plug-in groove 28, and the first magnetic sheet and the second magnetic sheet cooperate with each other.

[0039] This connection method makes the connection between the guide plate 23 and the first thumb cylinder 21 more stable, and also facilitates installation and disassembly. When the guide plate 23 needs to be installed, simply insert the plug block 27 into the plug slot 28. Under the attraction of the magnetic sheet, the guide plate 23 can be accurately fixed to the first thumb cylinder 21. When disassembly is required, simply apply a certain external force to overcome the attraction of the magnetic sheet. Example 3: This application discloses an automated shielding ring installation device.

[0040] Reference Figure 6 The difference between Embodiment 3 and Embodiment 1 of this application is that: a movable groove 51 is provided on the upper surface of the mounting base 31, and a positioning plate 5 is movably installed in the movable groove 51. The positioning plate 5 is used to abut against the end of the cable; a spring 52 is provided on the positioning plate 5 and the inner wall of the movable groove 51, and the elastic force of the spring 52 is used to drive the positioning plate 5 to move away from the mounting base 31.

[0041] The positioning plate 5 ensures that the end of each cable is at the same distance relative to the second clamping component 3, thus keeping the moving path length of the first clamping component 2 the same each time it works.

[0042] In this embodiment, the positioning plate 5 is provided with a guide surface 53 for guiding itself to move toward the movable groove 51. The guide surface 53 is inclined and is used to abut against the guide plate 23. When the guide plate 23 moves with the first thumb cylinder 21, the guide plate 23 abuts against the guide surface 53, pushing the positioning plate 5 into the movable groove 51 to make room for the installation of the shielding ring.

[0043] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
