The problem of difficult processing of mobile phone wire harnesses has also become a problem to be solved in mobile phone production.

[0030] A multi-directional wire harness clamping device comprises an annular gear seat 3, one end surface of which is provided with an annular raised track 32, and the side wall of which is circumferentially provided with saw teeth 31; a support frame 4, used to support the annular gear seat 3; a wire clamping device 5, which is installed on the annular gear seat 3 and slides in annularly on the annular gear seat 3 through the annular raised track 32 and the circumferentially provided saw teeth 31, so as to clamp the wire harness to be processed 360°.

[0031] Among them, the specific implementation parties in this embodiment include: the overall structure of the annular gear seat 3 is annular, and serrations 31 are provided on the outer side wall of the annular ring. The serrations 31 are evenly arranged on the side wall and circumferentially cover the side wall of the annular gear seat 3. The annular gear seat 3 is installed on the support member, and the wire clamping device 5 can slide circumferentially on the annular gear seat 3 through the serrations 31 and the annular raised track 32. Since the wire clamping device 5 can slide circumferentially, the wire clamping device 5 can identify and clamp the wire harness to be processed 360°.

[0032] In a preferred embodiment, the wire clamping device 5 includes a mounting panel 52, a wire clamping assembly 51, a gear 53, and a driving motor 54; the wire clamping assembly 51, the gear 53, and the driving motor 54 are mounted on the mounting panel 52; the mounting panel 52 is provided with a roller assembly 521 adapted to the annular raised track 32, and the outer side walls of the roller assembly 521 are respectively engaged with the sides of the annular gear seat 3, and the arrangement of the roller assembly 521 is specifically shown in the structure shown in the figure, and will not be described in detail. The driving motor 54 drives the gear 53 to rotate, and the gear 53 is adapted to the sawtooth 31 and drives the mounting panel 52 to move along the annular raised track 32; the wire clamping assembly 51 is used to clamp the wires in the lantern-shaped wire harness.

[0033] In this embodiment, the mounting panel 52 is a bridge connecting the wire clamping device 5 and the annular gear seat 3. A slide groove is provided on the mounting panel 52. The wire clamping device 5 is adapted to the annular raised track 32 through the slide groove so that the mounting panel 52 slides along the annular raised track 32 of the annular gear seat 3. The annular gear seat 3 is a track concentrically arranged with the annular gear seat 3, and its radius is larger than the inner ring wall radius of the annular gear seat 3 and smaller than the outer ring wall radius of the annular gear seat 3. In order to drive the mounting panel 52 to move along the annular raised track 32, a gear 53 adapted to the sawtooth 31 is provided. The gear 53 rotates and meshes with the sawtooth 31, so that the mounting panel 52 has multiple power to move.

[0034] The roller assembly 521 includes four rollers clamped on both sides of the annular gear seat 3, and the rollers are used to carry the mounting panel 52 and drive the mounting panel 52 to slide on the annular gear seat 3.

[0035] In a preferred embodiment, the drive motor 54 is a stepper motor or a servo motor. The present invention is not limited to these two embodiments, and other motors that can control the rotation direction of the gear 53, rotate and freeze quickly, and have a brake function are also acceptable.

[0036] Among them, a roller assembly 521 that engages with the annular gear seat 3 is provided on the installation panel 52. The roller assembly 521 is not only used to guide the movement of the installation panel 52, but also to install the installation panel 52 on the annular gear seat 3.

[0037] In a preferred embodiment, the wire clamping assembly 51 includes a wire clamp 511, a power platform that is tilted and used to drive the wire clamp 511 to clamp the wire, and a power assembly 513 that drives the power platform to move; the motion trajectory of the power assembly 513 driving the wire clamp 511 to complete a wire harness clamping through the power platform is a parallelogram.

[0038] In a preferred embodiment, the wire clamping assembly 51 includes a wire clamp 511, a power platform that is tilted and used to drive the wire clamp 511 to clamp the wire, and a power assembly 513 that drives the power platform to move; the power assembly 513 includes a driver mounting plate 5131 that is slidably connected to the power platform, a first linear driver 5132 that is vertically connected to the power platform and drives the power platform to slide on the driver mounting plate 5131, and a second linear driver 5133 that is mounted on the wire clamping base adapter plate and abuts against the driver mounting plate 5131 and is tilted in the same direction as the power platform; the first linear driver 5132 is used to drive the power platform to move linearly in the vertical direction; the second linear driver 5133 is used to drive the power platform to move linearly in the tilted direction. The power platform is slidably connected to the driver mounting plate 5131, and the power platform is used to drive the wire clamp 511 to open and close the pneumatic clamping finger 512, wherein the finger of the pneumatic clamping finger 512 is the clamping claw of the wire clamp 511.

[0039] The pneumatic clamping finger 512 is arranged obliquely, which means that the overall arrangement of the pneumatic clamping finger 512 forms an acute angle with the y-axis shown in the figure, and the acute angle can be 30°, 45° or 60°, which can be designed according to the needs of the present invention. The clamping claw of the wire clamp 511 is used to drive the opening and closing of the wire clamp 511. When the wire clamp 511 is opened, the wire clamp 511 is extended to both sides of the target wire in the wire harness. For example, if the target wire is a ground wire, the wire clamp 511 is extended to both sides of the ground wire, and then the clamping claw of the wire clamp 511 clamps the wire clamp 511, and the tip of the wire clamp 511 is closed to clamp the ground wire.

[0040] The power assembly 513 includes a driving member mounting plate 5131 which is slidably connected to the pneumatic clamping finger 512, a first linear driving member 5132 which is slidably connected to the upper end surface of the driving member mounting plate 5131 and vertically connected to the pneumatic clamping finger 512, and a second linear driving member 5133 which is mounted on the wire clamping base adapter plate, abuts against the driving member mounting plate 5131 and is inclined in the same direction as the pneumatic clamping finger 512. The second linear driving member 5133 which is inclined in the same direction here means that the overall linear direction of the second linear driving member 5133 is in a straight line with the overall direction of the pneumatic clamping finger 512, so the overall directions of the driving member mounting plate 5131, the pneumatic clamping finger 512 and the second linear driving member 5133 are in a straight line; the driving member mounting plate is a rectangular plate, the upper surface of the driving member mounting plate 5131 is slidably mounted on the first linear driving member 5132, and the lower surface of the driving member mounting plate is fixedly mounted on the second linear driving member 5133. The first linear driving member 5132 is used to drive the clamping jaw of the wire clamp 511 to move in a vertical direction; the second linear driving member 5133 is used to drive the clamping jaw of the wire clamp 511 to move in a linear direction in an inclined direction.

[0041] The first linear driving member 5132 includes a first adapter plate 51321 slidably connected to the driving member mounting plate 5131, and a first linear cylinder 51322 connected to the first adapter plate 51321 and used to drive the first adapter plate 51321 to move vertically. When the first adapter plate 51321 is installed with the pneumatic clamping finger 512, its installation part is sleeved on the pneumatic clamping finger 512 and has a part extending vertically downward from the side wall of the pneumatic clamping finger 512 on which the first adapter plate 51321 is fixed, and the part is the first linear cylinder 51322 mounting plate, and the first linear cylinder 51322 is fixed to the first linear cylinder 51322 mounting plate. When the first linear cylinder 51322 reciprocates up and down, it drives the pneumatic clamping finger 512 to move up and down; for example, the first linear power cylinder moves vertically upward, driving the first linear cylinder 51322 mounting plate to move upward, and the first linear cylinder 51322 mounting plate drives the overall first adapter plate 51321 to move upward. Since the pneumatic clamping finger 512 and the first adapter plate 51321 are fixed and the pneumatic clamping finger 512 is slidably connected to the drive member mounting plate 5131, the upward movement of the first linear cylinder 51322 will cause the first adapter plate 51321 to drive the pneumatic clamping finger 512 to slide obliquely upward on the upper surface of the drive member mounting plate 5131 as shown in the figure. The oblique upward direction is the inclination direction of the upper surface of the drive member mounting plate 5131 in the figure. It can also be seen from the structure in the figure that when the pneumatic clamping finger 512 slides upward in the inclination direction of the plane, the pneumatic clamping finger 512 drives the clamp 511 jaw to perform a fine-tuning and rise.

[0042] The second linear drive member 5133 includes a second linear cylinder 51331 whose fixed end is mounted on the clamping base adapter plate, and a second adapter plate 51332 mounted on the output end of the second linear cylinder 51331. The fixed end of the first linear cylinder is fixed on the second adapter plate 51332. The second adapter plate 51332 is arranged at the output end of the second linear cylinder 51331 to ensure that the first linear drive member 5132 can be driven to move in the coarse position adjustment link on the pneumatic clamping finger 512, so as to facilitate the subsequent fine adjustment of the pneumatic clamping finger 512 by the first linear drive member 5132.

[0043] The fixed end of the first linear cylinder 51322 of the first linear drive member 5132 can also be on a separate bracket, and the bracket can be provided with a slide rail in the X and Y directions. A lifting structure is provided on the bracket and fixedly connected with the clamping claw of the clamping base clamp 511. The slide rails in the X and Y directions and the lifting structure adjustable in the Z direction can make the lifting structure move with the movement of the pneumatic clamping finger 512, and then fine-tune the pneumatic clamping finger 512 in the Z direction.

[0044] The clamping jaws of the wire clamp 511 include clamping fingers arranged on pneumatic clamping fingers 512, and the pneumatic clamping fingers 512 can drive the clamping fingers to open and close. The clamping fingers can be composed of two rectangular blocks with an obtuse angle, and the pneumatic clamping fingers 512 can drive the clamping fingers to close and open. The specific driving method can be that the pneumatic clamping fingers 512 are two cylinder structures, the output end of one cylinder is connected to the left clamping piece, and the output end of the other cylinder is connected to the right clamping piece. Of course, this wire clamping base can also be a screw nut structure, and the clamping fingers are provided with threaded holes and are sleeved on two opposite screws, and when the screws rotate, the clamping fingers are driven to clamp or loosen.

[0045] The driver mounting plate 5131 is provided with a groove slide rail, and the pneumatic gripper finger 512 is provided with a protrusion that slides on the groove slide rail. In order to allow the pneumatic gripper finger 512 to slide on the mounting plate, a slide rail structure can be set at both ends, and preferably a slide groove, that is, a groove slide rail, is set on the mounting plate.

[0046] The wire clamp 511 includes a left clamp 5111 and a right clamp 5112. The left clamp 5111 and the right clamp 5112 include a clamp root installed on the pneumatic clamp finger 512 and a tip for clamping the wire harness. The opening and closing of the clamp jaws of the wire clamp 511 is used to drive the opening and closing of the left clamp 5111 and the right clamp 5112. As shown in the figure, the wire clamp 511 is provided with two groups. Due to work needs, when two groups of wires, that is, two groups of ground wires, need to be removed, the two groups of wire clamps 511 can be installed on the lower surface of the pneumatic clamp finger 512 at the same time, that is, the clamps present an L shape from the root to the tip. The left clamp 5111 and the right clamp 5112 can also be arranged in a cross-arrangement. Here, the cross-arrangement refers to an "×" arrangement. When the clamp jaws of the wire clamp 511 are closed, the upper part of the intersection is clamped, so that the left clamp 5111 and the right clamp 5112 clamp the wire group.

[0047] The parallelogram motion trajectory of the wire clamping assembly 51 is specifically as follows: when the device is moving, it first drives the second linear cylinder 51331 to drive the clamping jaws of the wire clamp 511 to make a rough adjustment in a position, so that the clamping jaws of the wire clamp 511 move to the bottom of the wire harness and are very close to the wire harness in the vertical direction, and then drives the first linear cylinder to move vertically upward so that the clamping jaws of the wire clamp 511 drive the wire clamp 511 to penetrate into the gap between the wires, and the pneumatic clamping fingers 512 close the clamping fingers so that the wire clamp 511 clamps the wires; then drives the second linear cylinder 51331 to move obliquely downward, the target wire is pulled out, and then the second linear cylinder 51331 moves downward to completely pull down the pulled out wire to separate it from the wire harness.

[0048] Among them, the specific operation of the clamping part includes the following steps:

[0049] The second linear cylinder 51331 is driven to drive the power platform to move upwards in an inclined manner until the wire clamp 511 on the power platform moves to the position directly below the wire harness to be processed;

[0050] The first linear cylinder 51322 is driven to drive the power platform to move vertically upward until the left clamping piece 5111 and the right clamping piece 5112 of the wire clamp 511 penetrate into the wire harness;

[0051] The power platform drives the left clamping piece 5111 and the right clamping piece 5112 to clamp the wire;

[0052] The second linear cylinder 51331 is driven to drive the power platform to tilt downward and drive the wire clamp 511 to pull out the clamped wire;

[0053] Driving the first linear cylinder 51322 to drive the power platform vertically downward and drive the wire clamp 511 to separate the wire from the wire bundle;

[0054] The power platform drives the wire clamp 511 to open and obtain the wire.

[0055] A preferred embodiment further includes a limit assembly 6 and a twisting harness module 2; the twisting harness module 2 is arranged on the twisting harness base 1, the twisting harness module 2 includes a first sliding assembly 21 installed on the twisting harness base 1, and a twisting assembly 22 slidably connected to the first sliding assembly 21, the twisting assembly 22 presses the other end of the harness toward the clamped end under the drive of the first sliding assembly 21 until the harness is pressed into a lantern shape; the limit assembly 6 is installed at the center of the cavity of the annular gear seat 3 through a connecting member 7, and is used to clamp one end of the harness to keep it stationary. The first sliding assembly 21 includes a base slider 211 sleeved on the twisting assembly 22, a slider track 212 slidably connected to the base slider 211, and a first sliding assembly 21 cylinder that drives the base slider 211 to reciprocate linearly on the slider track 212.

[0056] The first sliding component 21 includes a base slider 211 sleeved on the wire twisting component 22 , a slider track 212 slidably connected to the base slider 211 , and a first sliding component motor 213 driving the base slider 211 to move back and forth linearly on the slider track 212 .

[0057] The twisted wire harness base 1 may be a cubic support, or may be composed of two support columns arranged between an upper panel and a lower panel, wherein the upper panel is used to install the limit assembly 6 and the twisted wire assembly 22 .

[0058] In a preferred embodiment, the wire twisting assembly 22 includes an electric clamping finger 222, a first clamping jaw assembly 221 and a rotating motor 223 respectively installed at both ends of the electric clamping finger 222, the rotating motor 223 is used to drive the first clamping jaw assembly 221 to twist the wire harness, and the second clamping jaw assembly 224, the second clamping jaw assembly 224 includes an upper clamping block 2241, a lower clamping block 2242, and a second power assembly 2243 that drives the upper clamping block 2241 and the lower clamping block 2242 to close and clamp the wire harness.

[0059] In a preferred embodiment, the first clamping jaw assembly 221 includes a left clamping block 2211 and a right clamping block 2212, and the left clamping block 2211 and the right clamping block 2212 form a first cavity for clamping the wiring harness when they are closed; the upper clamping block 2241 and the lower clamping block 2242 form a second cavity for clamping the wiring harness when they are closed; the inner wall of the first cavity is rougher than the inner wall of the second cavity; the direction in which the second clamping jaw assembly 224 twists the wiring harness is opposite to the direction in which the first clamping jaw assembly 221 twists the wiring harness.

[0060] A preferred embodiment further includes an L-shaped bracket arranged on the annular gear seat 3, the limiting assembly 6 includes a transmission mechanism 62 installed on the L-shaped bracket and a third clamping jaw assembly 61 driven to open and close by the transmission mechanism 62, and the third clamping jaw assembly 61 includes a left clamping jaw 611 and a right clamping jaw 612.

[0061] The transmission mechanism 62 includes a power source, a fixed block 621, a first transmission rod 623, a second transmission rod 624, a vertical slider, a vertical slide rail 627, a third transmission rod 625 and a fourth transmission rod 626; wherein, a power rod 622 extends from the lower part of the fixed block 621, one end of the first transmission rod 623 and the second transmission rod 624 are respectively connected to the power rod 622, the other ends of the first transmission rod 623 and the second transmission rod 624 are respectively hinged to one end of the third transmission rod 625 and the fourth transmission rod 626, the other ends of the third transmission rod 625 and the fourth transmission rod 626 are respectively hinged to the vertical slider, the vertical slider slides on the vertical slide rail 627 and is fixedly connected to the power source.

[0062] Among them, the limit assembly 6 is mainly used to fix the wire harness, because when processing the wire harness, the wire harness needs to be twisted and pressed into a lantern shape, and one end of the wire harness to be processed needs to be kept stationary. The stationary mentioned here means neither rotating nor moving. When the twisting assembly 22 twists the wire harness, one end of the wire harness needs to remain stationary, so the limit assembly 6 is used to clamp the critical position of the non-processing end and the processing end of the wire harness to be processed, and then the twisting assembly 22 begins to twist the wire harness. The twisting assembly 22 performs the first twist according to the winding direction of the wire harness. If the wire harness is wound clockwise, the wire harness is twisted clockwise, that is, the original winding direction of the wire harness is pre-tightened, because if the wire harness is not pre-tightened, the wire harness is twisted counterclockwise directly. When the wire harness already shows signs of spreading, it is twisted counterclockwise, so that the wire harness is twisted into a wire harness wound in another direction again. The wire harness is not opened, so the wire harness needs to be pre-tightened first, and then the wire harness is twisted in the opposite direction to loosen the wire harness. The first clamping jaw assembly 221 in the wire twisting assembly 22 can complete the pre-tightening and loosening of the wire harness.

[0063] In order to better complete the pre-tightening of the wire harness in the original winding direction, the twisting assembly 22 also includes a second clamping jaw assembly 224, which includes an upper clamping block 2241, a lower clamping block 2242, and a second power assembly 2243 that drives the upper clamping block 2241 and the lower clamping block 2242 to close and clamp the wire harness. When the upper clamping block 2241 and the lower clamping block 2242 are closed, a columnar second cavity for clamping the wire harness is formed. The first clamping jaw assembly 221 includes a left clamping block 2211 and a right clamping block 2212, and the left clamping block 2211 and the right clamping block 2212 also form a first cavity for clamping the wire harness. The inner wall of the first cavity is not smooth and the inner wall of the second cavity is not smooth, but the inner wall of the first cavity is rougher than the inner wall of the second cavity, that is, the second cavity is more suitable for pre-tightening the wire harness. If only the first clamping jaw assembly 221 is used to pre-tighten the wire harness, when rotating, the wire harness may be too hard, and when rotating in the opposite direction, the wire harness is easily damaged. Therefore, the second clamping jaw assembly 224 in the twisting assembly 22 is required to pre-tighten the wire harness in the original direction. The second power assembly 2243 is the second clamping jaw assembly 224 cylinder, and the second clamping jaw assembly 224 cylinder drives the upper clamping block 2241 and the lower clamping block 2242 to clamp the wire harness. The clamping method is: when the upper clamping block 2241 and the lower clamping block 2242 are closed, a cylindrical second cavity will be formed. The diameter of this second cavity is slightly smaller than the wire harness. The inner wall of the second cavity is smoother than the inner wall of the first cavity, so that the clamping force on the wire harness is not as strong as the first clamping jaw assembly 221, so the damage to the wire harness caused by repeated twisting will not be great. In order to enhance the effect of pre-tightening the wire harness, a thread or multiple protrusions that enhance friction are provided on the inner wall of the second cavity to increase the friction between the inner wall of the second cavity and the wire harness. The first clamping jaw assembly 221 includes a left clamping block 2211 and a right clamping block 2212, and a first power assembly 2213 that drives the left clamping block 2211 and the right clamping block 2212 to clamp the wire harness. The first power assembly 2213 is a linear pneumatic finger, and the linear pneumatic finger includes two fingers for driving the left clamping block 2211 and the right clamping block 2212 to open and close. The left clamping block 2211 and the right clamping block 2212 are closed to clamp the wire harness.

[0064] The second power assembly 2243 is a cylinder of the second clamping jaw assembly 224 installed on the side wall of the electric clamping finger 222. Since the second clamping jaw assembly 224 clamps the wire harness in the up and down directions, in order to facilitate the installation of the first clamping jaw assembly 221, the clamping blocks of the second clamping jaw assembly 224 are arranged on the left and right sides, and a cavity is formed when the left clamping block 2211 and the right clamping block 2212 are closed, which is the first cavity. The diameter of the cavity is much smaller than the diameter of the second cavity, and the wire harness can be completely clamped, and the force applied to the wire harness will be greater.

[0065] In this embodiment, the specific structure of the limit assembly 6 is as follows: the power source is a cylinder or other linear motion structure on which a linear slide rail is arranged as a vertical slide rail 627. For example, the power source is a vertically arranged cylinder, and a slide groove is arranged on the surface of the cylinder as the vertical slide rail 627. The fixed block 621 is fixed to the twist and press harness base 1 through a bracket. The vertical slide rail 627 can be driven by the power source through the structure of the slide rail and cooperate with the fixed block 621 to complete the up and down sliding of the vertical slide rail 627. A power rod 622 extends out of the fixed block 621 to install the first transmission rod 623 and the second transmission rod 624. As shown in the figure, the right end of the power rod 622 is hinged to one end of the first transmission rod 623, and the left end of the power rod 622 is hinged to one end of the second transmission rod 624; then, one end of the fourth transmission rod 626 is hinged to the end of the first transmission rod 623 away from the power rod 622, and one end of the second transmission rod 624 away from the power rod 622 is hinged to one end of the third transmission rod 625, and one end of the fourth transmission rod 626 away from the first transmission rod 623 is hinged to the vertical slider. One end away from the second transmission rod 624 is hinged to the vertical slider, the fourth transmission rod 626 coincides with the hinge point of the third transmission rod 625 and the vertical slide rail 627, and the vertical slide rail 627 is hidden between the fixing block 621 and the vertical slide rail 627. When the wire harness is clamped, the first transmission rod 623, the second transmission rod 624, the third transmission rod 625, and the fourth transmission rod 626 form an isosceles triangle with the first transmission rod 623 and the second transmission rod 624 as the base; when the wire harness is released, the first transmission rod 623, the second transmission rod 624, the third transmission rod 625, and the fourth transmission rod 626 form a quadrilateral.

[0066] The specific operation of the present device in practical application is that first, the limit assembly 6 and the twisting harness module 2 complete the twisting of the harness into a lantern shape, and then drive the wire clamping device 5 to rotate 360° on the annular gear seat 3 to find the clamping target. The wire clamp 511 in the wire clamping device 5 completes the clamping of the wire once through a parallelogram path. Among them, the annular gear seat 3 is also provided with an identification device 8. In order to identify the target wire in the harness and to operate the wire clamping device 5 to rotate to the target position, the specific operation principle of the identification device 8 can be seen in the patent application document CN110246156A, wherein three identification devices 8 are evenly arranged on the back plate of the annular gear seat 3, and the harness can be accurately identified. In addition, as assembled as shown in the figure, the present device does not interfere with the work of other structures due to position reasons.

[0067] In order to efficiently complete the wire harness identification and clamping work, a plurality of wire clamping devices 5 can be provided on the annular gear seat 3, and each of the wire clamping devices 5 can work and be controlled independently.

[0068] In addition, the drawings of the present device can provide a more accurate description of the structure of the present device, and the description of the present device needs to be combined with the drawings.

[0069] The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments can be combined with each other to form new embodiments. The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any modification or equivalent replacement that does not deviate from the spirit and scope of the present invention shall be included in the scope of the technical solutions of the present invention.
