Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

The production process of the flexible cable is simply introduced, the production of the flexible cable needs to be carried out through a plurality of processes such as blanking, carrying, forming, fixing, mounting of accessory parts and packaging, the blanking process can be completed by using automatic blanking equipment at present, but the blanking process still needs to be carried out manually in the forming process, because the forming process involves bending, the machine is difficult to realize, and the flexible cable has certain flexibility and is difficult to form.

Further, the continuity of the above-described steps is relatively poor, and for example, in three steps of blanking, molding, and attaching accessory parts, it is necessary to circulate between different facilities.

Referring to fig. 1 to 3, a flexible cable constraint molding system disclosed in an embodiment of the present application is mainly composed of a working platform 11, a first working platform 12, a second working platform 13, a cable feeding device 14, a first beam-shaped portion 21, and a second beam-shaped portion 22.

First workstation 12 and second workstation 13 are all installed on work platform 11, and wherein first workstation 12 is fixed mounting on work platform 11, and unable removal, second workstation 13 and work platform 11 are sliding connection, can move to the direction that is close to and keeps away from first workstation 12.

The thread feeding device 14 is located between the first work table 12 and the second work table 13, and is also fixedly mounted on the work table 11.

The first bundling part 21 and the second bundling part 22 are respectively installed on the first workbench 12 and the second workbench 13, in the working process, the wire feeding device 14 feeds one end of the flexible cable into the first bundling part 21, one end of the flexible cable starts to be molded along with the continuous entering of the flexible cable, then the second workbench 13 moves towards the direction close to the wire feeding device 14, at the moment, the other end of the flexible cable enters the second bundling part 22, and one end of the flexible cable located in the second bundling part 22 starts to be molded along with the continuous moving of the second workbench 13.

After the second workbench 13 stops moving, the two ends of the flexible cable are all finished with molding work, at the moment, the manipulator can fix the wire clip on the flexible cable, fix the shape of the flexible cable, and finally take down the flexible cable.

In the whole production process, the subsequent forming and fixing processes can be automatically completed only by placing the flexible cable on the cable feeding device 14, and compared with a manual production mode, the production efficiency is obviously higher, and the accuracy degree is higher.

It has integrated beam type and subsequent fixed process, namely, can directly carry out fixing work after beam type is accomplished, and it should be understood that fixed process is exactly to use the line checkpost to fix the part that flexible cable contacted, and this is just can accomplish automatically with the manipulator.

From the perspective of the production process, the production of the flexible cable is divided into three processes of blanking, constraint forming and packaging, and compared with the original production process, the production process has the advantages of obviously fewer process steps, higher automation degree and higher production speed.

Referring to fig. 2 and 3, as an embodiment of the flexible cable constraint forming system provided by the application, the wire feeding device 14 mainly comprises four parts, namely a bracket 141, a rotating shaft 142, a friction wheel 143 and a driving device 144, wherein the bracket 141 is fixedly installed on the working platform 11. The rest of the bracket 141 of the rotating shaft 142 is rotatably connected and can rotate under the action of external force, and the friction wheel 143 is fixedly installed on the rotating shaft 142 and can rotate along with the rotation of the rotating shaft 142.

The driving device 144 is fixedly installed on the working platform 11 or the bracket 141, and is used for driving the rotating shaft 142 to rotate, in some possible implementation modes, the driving device 144 is composed of a servo motor and a precision servo speed reducer, an output end of the servo motor is connected to an input end of the precision servo speed reducer, and an output end of the precision servo speed reducer is connected to the rotating shaft 142.

It should be understood that the flexible cable is static friction between the two during the rotation of the friction wheel 143, that is, the advancing speed of the flexible cable is equal to the maximum linear speed of the friction wheel 143, and the position of the flexible cable is required during the bundling process, so that a servo motor is required for precise control.

Referring to fig. 4, the number of the rotating shafts 142 is two, and similarly, the number of the friction wheels 143 is two, and a gap is formed between the two friction wheels 143 for the flexible cable to pass through. During operation, the two friction wheels 143 simultaneously apply pressure to the flexible cable in contact therewith, causing it to move.

Further, the number of the wire feeding devices 14 is increased to two, and after the number of the wire feeding devices is increased to two, the two sets of friction wheels 143 can clamp the flexible cable at the same time, so that the possibility that the flexible cable slides relative to the friction wheels 143 in the moving process (the sliding occurs in the moving direction perpendicular to the flexible cable) is effectively reduced, and one end of the flexible cable cannot accurately enter the second beam-shaped portion 22.

Referring to fig. 4, further, the annular groove 145 is added to the friction wheel 143, so that the flexible cable passes through the channel formed by the two annular grooves 145, on one hand, the contact area with the friction wheel 143 is larger, and relative sliding (the sliding occurs in a direction parallel to the moving direction of the flexible cable) is less likely to occur, and on the other hand, the possibility of relative sliding (the sliding occurs in a direction perpendicular to the moving direction of the flexible cable) between the flexible cable and the friction wheel 143 can also be reduced.

Referring to fig. 5, as a specific embodiment of the flexible cable constraint molding system provided by the application, the first beam-shaped portion 21 mainly includes a base 211 and a beam-shaped cavity 212, the base 211 is fixedly mounted on the first worktable 12, the beam-shaped cavity 212 is located in the base 211, an input end and an output end of the beam-shaped cavity are both open ends, that is, the input end and the output end are communicated with an outer side surface of the base 211, and after the flexible cable enters the beam-shaped cavity 212 through the input end, the flexible cable starts to deform under the constraint of the beam-shaped cavity 212, and finally, one end of the flexible cable extends out from the output end.

In some possible implementations, the input and output ends of the bundle cavity 212 are a through hole.

In some possible implementations, the top end of the beam cavity 212 communicates with the top surface of the base 211, and the fixed flexible cable can be directly taken out of the beam cavity 212 after the beam is completed. Of course, a cover plate may be added to the base 211, the bundling cavity 212 is covered by the cover plate during the bundling process, and after the bundling is completed, the cover plate is removed, and then the fixed flexible cable is directly taken out from the bundling cavity 212.

Referring to fig. 6, as an embodiment of the flexible cable constraint molding system provided by the application, a beam rod 213 is additionally installed in the beam cavity 212, and the beam rod 213 is slidably connected to the beam cavity 212 and can move toward and away from the center of the beam cavity 212, so as to adjust the moving track of the flexible cable.

It should be understood that the dimensions of the bundle cavity 212 are fixed, so that only one specification or one type of product can be produced, the range of application is narrow, and after the bundle rod 213 is added, the shape of the bundle cavity 212 can be changed, so that the deformed cables of various specifications can be produced.

The power for the movement of the bunching rod 213 is provided by the telescopic device 214 on the base 211, the main body of the telescopic device 214 is fixedly installed on the base 211, the telescopic end of the telescopic device 214 is connected to the bunching rod 213, and when the telescopic end of the telescopic device 214 moves, the bunching rod 213 can be pulled to slide in the bunching cavity 212, so as to realize automatic adjustment.

In some possible implementations, the expansion device 214 uses an electric cylinder or an adjustable stroke cylinder.

Of course, it is also contemplated that the diameters of the flexible cables are different, and the height of the bundle cavity 212 may be increased appropriately for flexible cables with larger diameters, but it is not possible to effectively bundle flexible cables with smaller diameters because the flexible cables with smaller diameters are deformed within the bundle cavity 212 and the controller length cannot be precisely controlled.

Therefore, as an embodiment of the flexible cable constraint molding system provided by the application, please refer to fig. 7, a limiting post 215 is added on the middle portion of the bundle rod 213, the limiting post 215 divides the bundle rod 213 into two portions, each of the two portions is provided with a pressing block 216 and a spring 217, the spring 217 is sleeved on the bundle rod 213, and the pressing block 216 is slidably connected with the bundle rod 213 and is located between the limiting post 215 and the spring 217.

The spring 217 can push the pressing block 216 to press on the limiting column 215, so that after the flexible cable is contacted with the limiting column 215, the pressing blocks 216 on the two sides of the flexible cable are pushed to move towards the directions away from each other, but due to the limitation of the spring 217, the pressing blocks 216 can be tightly attached to the flexible cable, and therefore, for the flexible cable with different diameters, the moving track of the flexible cable can be limited by the pressing blocks 216.

The embodiment of the application also discloses a flexible cable production system, which comprises any one of the flexible cable constraint forming systems.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
