[0040] Combination Figures 1 to 9 An automatic sheath insertion device shown includes a sheath positioning mechanism 3, a line dividing mechanism 1, a line whole positioning mechanism 2 and a servo clamping and inserting mechanism 4.

[0041] Specifically, Figure 3As shown, the sleeve positioning mechanism 3 includes an intermediate base plate 311, a sleeve positioning channel 316, a block 317 and a claw 318. The intermediate base plate 311 is arranged parallel to the horizontal plane, and is used to support and fix the entire sleeve positioning mechanism 3. A third slide cylinder 314 and a block 317 are fixed above the intermediate base plate 311. The output shaft of the third slide cylinder 314 is fixedly connected to a cylinder connecting plate 312. The sleeve positioning channel 316 and a positioning cylinder 315 are fixed on the cylinder connecting plate 312. The positioning cylinder 315 is located at one end of the sleeve positioning channel 316. The output shaft of the positioning cylinder 315 is fixedly connected to a claw 318. The claw 318 can move on the sleeve positioning channel 316 relative to the block 317, and the moving direction of the claw 318 is parallel to the sleeve positioning channel 316.

[0042] In the above structure, the surface opposite to the block 317 and the claw 318 becomes the sleeve contact surface. Under the action of the third slide cylinder 314, the cylinder connecting plate 312 can make a linear motion parallel to the sleeve contact surface and parallel to the horizontal plane. Under the action of the positioning cylinder 315, the claw 318 can make a linear motion perpendicular to the sleeve contact surface.

[0043] Thus, the sleeve is placed on the sleeve positioning channel 316, the third slide cylinder 314 is started, and the end of the sleeve positioning channel 316 on the cylinder connecting plate 312 is moved to a position directly opposite to the sleeve contact surface of the block 317, and the positioning cylinder 315 is started. The output shaft of the positioning cylinder 315 pushes the claw 318, thereby pushing the sleeve on the sleeve positioning channel 316 to the sleeve contact surface of the block 317, thereby fixing the position of the sleeve.

[0044] like Figure 1 and Figure 6 As shown, the line dividing mechanism 1 is close to the end of the sleeve positioning channel 316 and close to the claw 318. The line dividing mechanism 1 includes a first slide cylinder fixing block 111, a line dividing needle fixing block 113 and a line dividing needle 114.

The first slide cylinder fixing block 111 is fixed with the first slide cylinder 112. The output shaft of the first slide cylinder 112 is fixedly connected with the line dividing needle fixing block 113. The line dividing needle fixing block 113 is fixedly connected with the line dividing needle 114 arranged perpendicular to the horizontal plane.

[0045] like Figure 2 and Figure 5 and Figure 8As shown, the whole-line positioning mechanism 2 is located above the line-dividing mechanism 1, and the whole-line positioning mechanism 2 includes a first clamping cylinder fixing block 212, a second slide cylinder fixing block 215, a line-dividing positioning block 216 and a shaping positioning block 213. The second slide cylinder fixing block 215 is arranged perpendicular to the horizontal plane to support and fix the entire whole-line positioning mechanism 2. The second slide cylinder 214 and the first clamping cylinder fixing block 212 are fixed on the second slide cylinder 214. The output shaft of the second slide cylinder 214 is fixedly connected to the line-dividing positioning block 216, and the output end of the first clamping cylinder 211 is connected to two shaping positioning blocks 213.

[0046] like Figure 5 and Figure 8 As shown, the line dividing positioning block 216 and the shaping positioning block 213 are located on the side of the line dividing needle 114 close to the sheath positioning mechanism 3. The line dividing positioning block 216 can move perpendicular to the horizontal plane under the action of the second slide cylinder 214. The line positioning mechanism 2 also has a first slide rail 217. The first slide rail 217 is located at the end of the output shaft of the first clamping cylinder 211 and is vertically fixed on the first clamping cylinder fixing block 212. The two shaping positioning blocks 213 are connected to the output shaft of the first clamping cylinder 211 and are slidably connected to the first slide rail 217. The shaping positioning blocks 213 are symmetrically arranged on both sides of the line dividing positioning block 216 and can move relative to each other or towards each other at the same time.

[0047] like Figure 5 and Figure 8 As shown, under the action of the second slide cylinder 214, the line dividing positioning block 216 can move in a direction perpendicular to the horizontal plane to just above the line dividing needle fixing block 113 and contact it.

[0048] In the above structure, the dividing line needle 114 moves in a direction perpendicular to the horizontal plane under the action of the first slide cylinder 112, and the dividing line positioning block 216 can move in a direction perpendicular to the horizontal plane under the action of the second slide cylinder 214, and can contact the upper surface of the dividing line needle fixing block 113, and does not interfere with the dividing line needle 114 during movement.

[0049] Thus, the wire harness with crimped terminals is transferred from the end of the wire splitting needle 114 away from the sheath positioning mechanism 3 to the top of the wire splitting mechanism 1, the first slide cylinder 112 is started, and the wire splitting needle 114 moves vertically upward, thereby separating the two wires with crimped terminals, and the two wires are placed on the upper surface of the wire splitting needle fixing block 113, and then the second slide cylinder 214 is started, and the wire splitting positioning block 216 moves vertically downward until it contacts the two wires on the upper surface of the wire splitting needle fixing block 113 and flattens the terminals on the two wires, and then the first clamping jaw cylinder 211 is started, and the two shaping positioning blocks 213 move close to the wire splitting positioning block 216 on the first slide rail 217 until the terminals of the two wires are pressed tightly so that the spacing between the two terminals is consistent with the inlet size of the sheath to be plugged in.

[0050] like Figure 4 and Figure 5 and Figure 7 As shown, the servo clamping and insertion mechanism 4 is located above the sheath positioning mechanism 3, and the servo clamping and insertion mechanism 4 and the sheath positioning mechanism 3 are arranged on the same side relative to the branching mechanism 1. The servo clamping and insertion mechanism 4 includes a servo module base plate 411, a single-axis driver base plate 413, a fourth slide cylinder base plate 418, a second clamping claw cylinder fixing block 420, and a sheath clamping claw 422. The servo module base plate 411 is located at the bottom of the entire servo clamping and insertion mechanism 4, and a vertical plate 412 is vertically fixed on the servo module base plate 411. The servo module base plate 411 and the vertical plate 412 are used to support and fix the servo clamping and insertion mechanism 4. A single-axis drive base plate is fixed above the vertical plate 412, and a single-axis driver 414, a shading plate 415 and a photoelectric switch 416 are fixed on the single-axis drive base plate. The shading plate 415 is used to block or To reduce the penetration of light, the photoelectric switch 416 uses the photoelectric principle to detect the existence or position of an object. In the assembly line production, the electric switch is used to detect the number of products passing through to achieve automatic counting and control. A servo motor 417 is also fixed on the single-axis drive base plate. The output shaft of the servo motor 417 is fixedly connected to the fourth slide cylinder base plate 418. A fourth slide cylinder 419 is fixed on the fourth slide cylinder base plate 418 perpendicular to the horizontal plane. The output shaft of the fourth slide cylinder 419 is fixedly connected to the second clamping cylinder fixing block 420. The second clamping cylinder 421 is fixed to the bottom of the second clamping cylinder fixing block 420, and the second clamping cylinder 421 is arranged parallel to the horizontal plane. The output shaft of the second clamping cylinder 421 is oriented in the direction of the line dividing mechanism 1, and the output shaft is connected to the sheath clamping jaw 422.

[0051] like Figure 4 As shown, the servo clamping and insertion mechanism 4 also has a second slide rail 423, which is located at the end of the output shaft of the second clamping cylinder 421 and is perpendicular to the horizontal plane. The sheath clamping jaw 422 includes two clamping jaws, which are slidably connected to the second slide rail 423.

[0052] like Figure 5 As shown, under the action of the servo motor 417, the sheath clamp 422 moves in a direction parallel to the horizontal plane, under the action of the fourth slide cylinder 419, the sheath clamp 422 moves in a direction perpendicular to the horizontal plane, and under the action of the second clamp cylinder 421, the two clamps of the sheath clamp 422 move relative to or towards each other on the second slide rail 423 at the same time.

[0053] In the above structure, under the action of the servo motor 417 and the fourth slide cylinder 419 , the sheath clamp 422 can move to just above the sheath positioning channel 316 , and the sheath clamp 422 can move to the branch line positioning block 216 and the shaping positioning block 213 .

[0054] When in use, the sheath is placed on the sheath positioning channel 316, the third slide cylinder 314 and the positioning cylinder 315 are started, the claw 318 pushes the sheath on the sheath positioning channel 316, thereby fixing the position of the sheath, and the wire harness with the crimped terminals is moved from the end of the branching needle 114 away from the sheath positioning mechanism 3 to the top of the branching mechanism 1, the first slide cylinder 112 is started, the branching needle 114 moves vertically upward, thereby separating the two wires with the crimped terminals, and then the second slide cylinder 214 and the first clamping claw cylinder 211 are started, the branching positioning block 216 flattens the terminals on the two wires, and the two shaping positioning blocks 213 press the terminals of the two wires so that the distance between the two terminals is larger than the inlet of the sheath to be plugged in. After the sheath positioning process and the branching and flattening terminal processes are completed, the servo motor 417 and the fourth slide cylinder 419 are started, and the sheath clamp 422 moves to the top of the sheath positioning channel 316, and the second clamp cylinder 421 is started. The two clamps of the sheath clamp 422 move relative to each other at the same time, so as to clamp the sheath on the sheath positioning channel 316. After the sheath clamp 422 clamps the sheath, it is moved to the branching positioning block 216 again under the action of the servo motor 417 and the fourth slide cylinder 419 to ensure that the sheath inlet is opposite to the terminals of the two wires, and then the servo motor 417 drives the sheath clamp 422 to move toward the branching positioning block 216 again, so as to automatically insert the sheath into the terminals of the two wires.
