[0035] Specifically, the wire harness processing device includes: a first driver 200 , an adapter 300 , a clamping mechanism 100 and a clamping unit 400 .

[0036] Specifically, the adapter 300 is transmission-connected to the power output end of the first driver 200 ; the clamping mechanism 100 is disposed on the adapter 300 ; and the clamping unit 400 is disposed on the adapter 300 .

[0037] The first driver 200 is used to drive the adapter 300 to move along the first direction X, so as to synchronously drive the clamping mechanism 100 and the clamping unit 400 to move along the first direction X, adjust the relative positions of the clamping mechanism 100 and the clamping unit 400, and at the same time, the clamping mechanism 100 and the clamping unit 400 cooperate to clamp and organize the wire harness.

[0038] The first driver 200 may be a driving cylinder or a driving motor. For example, in this application, the first driver 200 is a driving cylinder.

[0039] Specifically, refer to Figures 4 and 5 The clamping mechanism 100 includes: a first clamping driver 110 , a first transmission member 120 , a second transmission member 130 and a first clamping unit 140 .

[0040] Specifically, the first clamping driver 110 is arranged along the first direction X; the first transmission member 120 extends along the second direction Z, the first transmission member 120 is transmission-connected to the power output end of the first clamping driver 110, and at least two first transmission grooves 121 are provided on the first transmission member 120, and the first transmission grooves 121 are arranged at an angle relative to the second direction Z, that is, the first transmission grooves 121 are arranged obliquely relative to the second direction Z; at least two second transmission members 130 are provided. At least two second transmission members 130 are both arranged on the side of the first transmission member 120 away from the first clamping driver 110, and the second transmission member 130 includes: a first main body portion 131 and a first cam portion 132, the first cam portion 132 is connected to the side of the first main body portion 131 close to the first transmission member 120, and each first cam portion 132 can be movably arranged in a corresponding first transmission groove 121 to form a cam transmission structure between the first transmission member 120 and the second transmission member 130; the first clamping unit 140 includes: a first clamping member 141 and a second clamping member 142, the first clamping member 141 and the second clamping member 142 are respectively connected to a corresponding first main body portion 131, and the first clamping driver 110 drives the first clamping member 141 and the second clamping member 142 to approach or move away from each other through the cooperation between the first transmission member 120 and the second transmission member 130.

[0041] The first clamping driver 110 may be a driving cylinder or a driving motor. For example, in the present application, the first clamping driver 110 is a driving cylinder.

[0042] Among them, the first main body 131 and the first cam portion 132 can be integrally formed, that is, the first main body 131 and the first cam portion 132 are an integrated structure; the first main body 131 and the first cam portion 132 can also be separately provided, and the two are fixedly connected. For example, the first cam portion 132 is fixedly connected to the first main body 131 by riveting or screwing. This is not specifically limited in this application and can be specifically set according to actual circumstances. For example, the first main body 131 and the first cam portion 132 are separately provided, and the first cam portion 132 is screwed to the side of the first main body 131 close to the first transmission member 120 by bolts to facilitate assembly and molding between the two.

[0043] It can be understood that the first clamping driver 110 drives the first transmission member 120 to move along the first direction X through its own power output end. Due to the cam structure between the first transmission groove 121 and the first cam portion 132 between the first transmission member 120 and the second transmission member 130, the first cam portion 132 and the first transmission member 120 are relatively displaced. At the same time, since the first transmission groove 121 is set at an angle relative to the second direction Z, the first cam portion 132 is relatively displaced between the first transmission member 120 in the second direction Z, driving the two second transmission members 130 to approach or move away from each other, so as to drive the first clamping member 141 and the second clamping member 142 to approach or move away from each other, so that the first clamping driver 110 converts the movement of the driving transmission member in the first direction X into driving the first clamping member 141 and the second clamping member 142 to approach or move away from each other in the second direction Z.

[0044] The present application forms a cam transmission structure between the first transmission member 120 and the second transmission member 130, so that when the first clamping driver 110 drives the first transmission member 120 to move along the first direction X, the cam transmission structure is used to synchronously drive the two second transmission members 130 to approach or move away from each other in the second direction Z, thereby driving the first clamping member 141 and the second clamping member 142 to approach or move away from each other in the second direction Z, so as to enhance the clamping strength of the first clamping member 141 and the second clamping member 142 through the angle change of the cam angle, enhance the self-locking force of the clamping mechanism 100, and ensure the clamping effect of the clamping mechanism 100; at the same time, the cam transmission structure occupies a small space, ensures the structural strength of the first transmission member 120 and the second transmission member 130, increases the stability of the mechanism, and increases the service life of the first transmission member 120 and the second transmission member 130.

[0045] In one embodiment, referring to Figures 4 and 5 The two first transmission grooves 121 are mirror-imaged in the second direction Z to ensure the synchronization of the two second transmission members 130 driven by the cam transmission structure, to ensure the synchronization of the first clamping member 141 and the second clamping member 142, and thus to ensure the clamping strength of the first clamping member 141 and the second clamping member 142, to enhance the self-locking force of the clamping mechanism 100, and to ensure the clamping effect of the clamping mechanism 100.

[0046] In one embodiment, referring to Figures 4 and 5 The wire harness processing device has a reference plane P perpendicular to the third direction Y; along the third direction Y, the orthographic projection of the groove wall of the first transmission groove 121 on the reference plane P is either a straight line or an arc shape, that is, the orthographic projection of the groove wall of the first transmission groove 121 on the reference plane P can be a straight line or an arc shape, but is not limited to this, so as to facilitate the processing and forming of the first transmission groove 121, and then facilitate the overall assembly of the clamping mechanism 100.

[0047] In one embodiment, a positioning groove 1411 is provided on one side of the first clamping member 141 close to the second clamping member 142, and a positioning portion 1421 is provided on one side of the second clamping member 142 close to the first clamping member 141. The positioning portion 1421 is adapted to the positioning groove 1411, and the positioning portion 1421 can be selectively embedded in the positioning groove 1411.

[0048] In this application, the positioning portion 1421 cooperates with the positioning groove 1411 to facilitate the first clamping driver 110 to drive the first clamping member 141 and the second clamping member 142 to clamp the linear speed, thereby ensuring the clamping strength of the first clamping member 141 and the second clamping member 142.

[0049] In one embodiment, referring to Figures 4 and 5 The clamping mechanism 100 further includes: a connecting member 150, which is arranged between the first clamping driver 110 and the first transmission member 120, and the first transmission member 120 is transmission-connected to the power output end of the first clamping driver 110 through the connecting member 150.

[0050] It is understandable that if the first transmission member 120 is directly connected to the power output end of the first clamping driver 110 , the first cam portion 132 may directly rub against the first clamping driver 110 when the first transmission slot 121 moves, causing damage to the first clamping driver 110.

[0051] In this application, the first transmission member 120 is connected to the power output end of the first clamping driver 110 through the connecting member 150 to avoid direct contact between the first cam portion 132 and the first clamping driver 110, thereby avoiding damage to the first clamping driver 110; at the same time, the connection strength between the first clamping driver 110 and the first transmission member 120 is ensured to ensure the overall structural stability of the clamping mechanism 100.

[0052] In one embodiment, referring to Figures 4 and 5 The clamping mechanism 100 also includes: a fixed bracket 160 and a guide member 170; the fixed bracket 160 is provided with a accommodating cavity 161, the first clamping driver 110, the first transmission member 120 and the second transmission member 130 are all arranged in the accommodating cavity 161, and the first clamping driver 110 is fixedly connected to the fixed bracket 160; the guide member 170 is arranged between the fixed bracket 160 and the second transmission member 130, the guide member 170 extends along the second direction Z, and the second transmission member 130 is fixedly connected to the movable part of the guide member 170.

[0053] It can be understood that the present application arranges the first clamping driver 110, the first transmission member 120 and the second transmission member 130 in the accommodating cavity 161 to ensure the compactness of the overall structure of the clamping mechanism 100 and reduce the space occupied by the clamping mechanism 100; at the same time, by fixedly connecting the second transmission member 130 with the movable part of the guide member 170, the guide member 170 is used to guide the second transmission member 130, and then to guide the first clamping member 141 and the second clamping member 142, so as to prevent the first clamping member 141 and the second clamping member 142 from moving at will, thereby ensuring the accuracy of the clamping action of the first clamping member 141 and the second clamping member 142.

[0054] In one embodiment, the wire harness processing device further includes: a second driver 500, the second driver 500 is arranged on the adapter 300, and the second driver 500 is arranged along the first direction X, and the power output end of the second driver 500 is transmission-connected to the clamping mechanism 100; specifically, the power output end of the second driver 500 is transmission-connected to the fixed bracket 160, and the second driver 500 is used to drive the clamping mechanism 100 to move along the first direction X to adjust the relative position of the clamping mechanism 100, so as to facilitate the clamping mechanism 100 to clamp the wire harness.

[0055] The second driver 500 may be a driving cylinder or a driving motor. For example, in this application, the second driver 500 is a driving cylinder.

[0056] In one embodiment, referring to Figures 6 and 7 The clamping unit 400 includes: a second clamping driver 410 , a third transmission member 420 , at least two fourth transmission members 430 and at least two second clamping units 440 .

[0057] Specifically, the third transmission member 420 extends along the first direction X, the third transmission member 420 is transmission-connected to the power output end of the second clamping driver 410, and at least two second transmission grooves 421 are opened on the third transmission member 420, and the second transmission grooves 421 are arranged at an angle relative to the first direction X, that is, the second transmission grooves 421 are inclined relative to the second direction Z; at least two fourth transmission members 430 are arranged on the side of the third transmission member 420 away from the second clamping driver 410, and the fourth transmission member 430 includes: a second main body portion 431 and a second cam portion 432, the second cam portion 432 is connected to the side of the second main body portion 431 close to the third transmission member 420, and each second cam portion 432 can be movably arranged in a corresponding second transmission groove 421 to form a cam transmission structure between the third transmission member 420 and the fourth transmission member 430; at least two second clamping units 440 are respectively connected to a corresponding second main body portion 431, and the second clamping driver 410 drives the two second clamping units 440 to approach or move away from each other through the cooperation between the third transmission member 420 and the fourth transmission member 430.

[0058] The second clamping driver 410 can be any one of a driving cylinder and a driving motor. For example, in this application, the second clamping driver 410 is a driving cylinder.

[0059] It can be understood that the second clamping driver 410 drives the third transmission member 420 to move along the first direction X through its own power output end. Due to the cam structure between the second transmission groove 421 and the second cam portion 432 between the third transmission member 420 and the fourth transmission member 430, the second cam portion 432 and the third transmission member 420 are relatively displaced. At the same time, the second transmission groove 421 is set at an angle relative to the first direction X, so that the second cam portion 432 and the third transmission member 420 are relatively displaced in the third direction Y, driving the two fourth transmission members 430 to approach or move away from each other in the third direction Y, so as to drive the two second clamping units 440 to approach or move away from each other in the third direction Y, so that the second clamping driver 410 converts the movement of the driving transmission member in the first direction X into driving the two second clamping units 440 to approach or move away from each other in the third direction Y.

[0060] The present application forms a cam transmission structure between the third transmission member 420 and the fourth transmission member 430, so that when the second clamping driver 410 drives the third transmission member 420 to move along the first direction X, the cam transmission structure is used to synchronously drive the two fourth transmission members 430 to approach or move away from each other in the third direction Y, so as to drive the two second clamping units 440 to approach or move away from each other in the third direction Y, thereby ensuring the structural strength of the third transmission member 420 and the fourth transmission member 430, increasing the stability of the mechanism, and increasing the service life of the third transmission member 420 and the fourth transmission member 430.

[0061] In one embodiment, referring to Figures 6 and 7 The second clamping unit 440 includes: a third clamping driver 441 and at least two third clamping members 442; the two third clamping members 442 are both transmission-connected to the power output end of the third clamping driver 441, and the third clamping driver 441 is used to drive the two third clamping members 442 to move closer to or away from each other.

[0062] The third clamping driver 441 may be a driving cylinder or a driving motor. For example, in the present application, the third clamping driver 441 is a driving cylinder.

[0063] It can be understood that the present application drives the two third clamping members 442 to move closer to or away from each other through the third clamping driver 441, so as to utilize the third clamping members 442 to clamp and organize the wire harness, so that the second clamping unit 440 and the clamping mechanism 100 cooperate synchronously to clamp and organize the wire harness, thereby improving the working efficiency of the wire harness processing device.

[0064] The above steps are merely provided to help understand the method, structure, and core concept of the present application. A person skilled in the art may make several improvements and modifications to the present application without departing from the principles of the present application, and such improvements and modifications also fall within the scope of protection of the claims of the present application.
