Description

Technical Field

[0001] The utility model relates to the technical field of multi-axis motion controllers, in particular to a multi-axis motion controller based on wire harness processing. Background Art

[0002] Wire harness processing is a field that requires precise control and synchronized multi-axis motion. Multi-axis motion controllers play an important role in this field. During the wire harness processing, there is a high demand for processes such as short-circuit winding and heat shrinkage. In the multi-axis motion control system, the multi-axis motion controller itself may have one or more built-in CAN interfaces. The CANopen protocol can be implemented to more precisely control components such as motors, sensors and actuators. However, in the existing technology, installing CAN lines is more troublesome. The H / L lines need to be inserted into the ports separately, and then micro bolts are used to apply pressure to the locking iron sheet to limit the H\L lines. Utility Model Content

[0003] The utility model provides a multi-axis motion controller based on wire harness processing, which can lock the CAN line more efficiently and can also quickly unlock and unplug the CAN line, thereby improving the user experience of the multi-axis motion controller.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0005] A multi-axis motion controller based on wire harness processing, comprising:

[0006] A motion controller housing and multiple CAN interface devices thereon; the CAN interface device comprises a terminal housing and a wire trough opened inside the terminal housing, wherein the interior of the wire trough is designed as a signal contact terminal; the interior of the terminal housing is also provided with an assembly cavity connected to the wire trough, wherein a switch paddle is hingedly assembled inside the assembly cavity, and a functional shaft is installed on the outer wall of the switch paddle, and when the switch paddle is pressed inward, the functional shaft can apply pressure to the enameled layer of the CAN line to limit the offset or displacement of the CAN line; a lock is designed on the terminal housing to limit the rotation of the switch paddle.

[0007] Optionally, the locker includes a screw fixedly connected to the hinged end of the switch paddle, the screw is hinged on the inner wall of the assembly cavity, the outer wall of the terminal housing is provided with a limiting groove, a threaded sleeve is slidably installed in the limiting groove, the inner wall of the threaded sleeve is threadedly connected to the outer wall of the screw, and when the screw rotates, the threaded sleeve can be driven to slide in the limiting groove, and the inner wall of the limiting groove is designed with a damping design to increase the sliding friction of the threaded sleeve.

[0008] Optionally, the functional shaft is rotatably mounted on the outer wall of the switch paddle through a bearing seat, a rotating shaft is mounted on the bearing seat, the rotating shaft is coaxially fixed with the functional shaft, a worm gear is fixedly mounted on the outer wall of the rotating shaft, a worm is rotatably mounted on the switch paddle, the worm gear is meshed with the worm gear, and when the worm gear rotates, the functional shaft can be controlled to rotate to push the CAN line outward.

[0009] Optionally, the anti-slip coefficient between the threaded sleeve and the screw is greater than 0.45.

[0010] Optionally, the wire trough is a rectangular slot, and a sealing portion is installed at the connection between the wire trough and the assembly cavity. The sealing portion is composed of multiple petals, and the multiple petals are combined into a rectangular dustproof sheet.

[0014] The utility model provides a multi-axis motion controller based on wire harness processing, which has the following advantages:

[0015] 1. Through the coordination of the wire trough and the assembly cavity, the wire trough is designed for the insertion of the exposed end or the twisted end of the CAN line, completing the connection of the CAN line and also completing the protection of the CAN line.

[0016] 2. Through the cooperation between the functional shaft, the switch paddle and the locker, the CAN wire with the enameled layer will enter the assembly cavity. By pressing the switch paddle inward, the functional shaft on the switch paddle will apply pressure to the enameled layer, increasing the friction between the two and enhancing the locking ability of the CAN wire.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 9 The utility model provides a technical solution: a multi-axis motion controller based on wire harness processing, comprising:

[0030] A motion controller housing 1 and multiple CAN interface devices thereon; the CAN interface device includes a terminal housing 2 and a wire groove 5 opened therein, the interior of the wire groove 5 is designed as a signal contact end; the interior of the terminal housing 2 is also provided with an assembly cavity 6 connected to the wire groove 5, the interior of the assembly cavity 6 is hingedly equipped with a switch paddle 3, the outer wall of the switch paddle 3 is installed with a functional shaft 4, and when the switch paddle 3 is pressed inward, the functional shaft 4 can apply pressure to the enameled layer of the CAN line to limit the offset or displacement of the CAN line; a lock is designed on the terminal housing 2 to limit the rotation of the switch paddle 3.

[0031] In the prior art, the CAN line is directly inserted into the port, and then the iron sheet is pressed and deformed by bolts to fix the CAN line to complete signal connection and transmission. In this case, a more convenient way is used to lock the CAN line. Please refer to Figures 2 to 8 In this technical solution, the wire groove 5 is designed for inserting the exposed end or twisted end of the CAN line to complete the connection of the CAN line, and the CAN line with the enameled layer will enter the assembly cavity 6. By pressing the switch paddle 3 inward, the functional shaft 4 on the switch paddle 3 will apply pressure to the enameled layer. During the pressure application process, the contact area between the functional shaft 4 and the enameled layer of the CAN line will increase and the contact will be closer, thereby increasing the friction between the two and enhancing the locking ability of the CAN line. Therefore, compared with the existing technology, the utility model can lock the CAN line more efficiently and protect the exposed part of the CAN line at the same time.

[0032] The rotation of the switch paddle 3 is controlled by a locker, so that it can be adjusted according to actual conditions.

[0033] In a more preferred embodiment, the lock includes a screw 7 fixedly connected to the hinged end of the switch paddle 3, the screw 7 is hinged on the inner wall of the assembly cavity 6, and a limit groove is provided on the outer wall of the terminal housing 2. A threaded sleeve 8 is slidably installed in the limit groove. The inner wall of the threaded sleeve 8 is threadedly connected to the outer wall of the screw 7. When the screw 7 rotates, the threaded sleeve 8 can be driven to slide in the limit groove. The inner wall of the limit groove is designed with a damping design to increase the sliding friction of the threaded sleeve 8. Please refer to Figures 2 to 8 In this embodiment, by utilizing the cooperation between the screw rod 7 and the threaded sleeve 8, the switch paddle 3 can drive the threaded sleeve 8 to slide in the limit groove during the pressing or resetting process, and the threaded sleeve 8 can limit the free rotation of the screw rod 7, thereby ensuring the locking stability. Secondly, the restoring ability of the enamel layer of the CAN line is not enough to rotate the screw rod 7, and the damping design will increase the sliding friction of the threaded sleeve 8 in the limit groove, further limiting the free rotation of the screw rod 7 or the promotion of the restoring force of the CAN line, thereby ensuring the locking ability of the functional shaft 4 to the CAN line.

[0034] Based on the embodiment of the locker, the functional shaft 4 is rotatably mounted on the outer wall of the switch paddle 3 via a bearing seat. The bearing seat is mounted with a rotating shaft 9, which is coaxially fixed with the functional shaft 4. A worm gear 11 is fixedly mounted on the outer wall of the rotating shaft 9. A worm 12 is rotatably mounted on the switch paddle 3, and the worm 12 is meshed with the worm gear 11. When the worm 12 rotates, it can control the functional shaft 4 to rotate and push the CAN line outward. In the embodiment of the locker, the functional shaft 4 can complete the locking and limiting of the CAN line. However, there are two situations for disconnection: one is to completely unplug the CAN line, and the other is to temporarily disconnect the CAN line from the signal connection, which will be reconnected after a short period of time. When complete unplugging is required, the switch paddle 3 only needs to be reset to release the locking of the CAN line by the functional shaft 4. When temporary disconnection is required, the worm 12 can be rotated. The rotation of the worm 12 causes the worm gear 11 to drive the functional shaft 4 to rotate, causing the functional shaft 4 to push the CAN line outward by a corresponding distance, thereby displacing the exposed end of the CAN line outward, thereby disconnecting the CAN line from the signal contact end.

[0035] Furthermore, the anti-slip coefficient between the threaded sleeve 8 and the screw 7 is greater than 0.45. The value of the anti-slip coefficient, i.e., the anti-slip coefficient, should meet certain standards to ensure the stability of the threaded connection and prevent the screw from rotating. In this embodiment, in order to ensure that the displacement of the threaded sleeve does not drive the screw to rotate, the anti-slip coefficient should be at least 0.45 or higher to meet design and safety requirements.

[0036] In a more preferred embodiment, the wire slot 5 is a rectangular slot, and a sealing portion 13 is installed at the connection between the wire slot 5 and the assembly cavity 6. The sealing portion 13 is composed of multiple petals, and the multiple petals are combined into a rectangular dustproof sheet. The CAN line can break through the multiple petals and enter the interior of the wire slot 5. Please refer to Figure 9 Through the cooperation between multiple petals, the cable trough 5 can maintain a relatively high degree of sealing when not in use, preventing external dust and water from entering. At the same time, the petals are generally made of resettable flexible materials, which can allow the insertion of CAN lines, making it easier for CAN lines to access the system.

[0037] In order to improve the efficiency and stability of pushing out the CAN line during temporary disconnection, two implementation plans are proposed.

[0038] Example 1:

[0039] The circumferential array of the outer wall of the functional shaft 4 has multiple puncture groups, and the puncture groups include multiple linearly arranged cone thorns, see Figure 7In this embodiment, a puncture method is adopted. This method is used for long-term connection. In occasional situations where the line needs to be disconnected, such as serious situations such as line failure or damage, the CAN line needs to be disconnected. At this time, the execution success rate must be ensured. The puncture method can be used to limit the CAN line. The puncture method can also better ensure that the CAN line can be pushed out by the rotation of the functional shaft 4.

[0040] Example 2:

[0041] The circumferential outer wall of the functional shaft 4 has a plurality of ribs arranged in a circular array. The ribs are staggered or parallel to the axis of the functional shaft 4. Figure 8 In this embodiment, slipping is prevented by adding ribs. The ribs can be parallel to the axis of the functional shaft 4 or staggered with the axis of the functional shaft 4 to further improve the anti-slip ability. Secondly, the ribs can also be irregular.

[0042] Furthermore, the switch paddle 3 is a stepped structure, and the free end of the switch paddle 3 faces outward, which is convenient for the user to press and obtain better pressing feedback.

[0043] By utilizing the cooperation of the above structures, the utility model can lock the CAN line more efficiently, and can also quickly unlock and unplug the CAN line.

[0044] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
