Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

The gantry double-arm mechanism 4 is fixedly arranged in the middle of the frame 1. The glue-wrapping mechanism 5 and the bushing feeding device 2 are sequentially arranged on the frame 1 based on the front side of the gantry double-arm mechanism 4. The winding spindle three-coordinate mechanism 6 is fixedly arranged below the gantry double-arm mechanism 4. The right-angle pressing mechanism 7 is arranged on the winding spindle three-coordinate mechanism 6. The line-up device 3 is fixedly arranged on the gantry double-arm mechanism 4.

[0033] Figure 4 The overall structure of the gantry double-arm mechanism is shown schematically. Figure 4 As shown, the gantry double-arm mechanism 4 includes a gantry, and a wire feeding mechanism is fixedly arranged above the gantry. Movable arms are relatively arranged on both sides of the gantry, and the movable arms include a first movable arm 41 and a second movable arm 42. The first movable arm 41 and the second movable arm 42 are both driven by separate servo motors, and the servo motor is fixedly arranged on the motor screw linear module. The position of the first movable arm 41 and the second movable arm 42 is adjusted by the motor screw linear module. Therefore, the aforementioned motor screw linear module is fixed on both sides of the gantry, and a plurality of clamping claw assemblies are fixedly arranged on the aforementioned first movable arm 41 for clamping the wire and completing the wire feeding process, and a cutting mechanism is fixedly arranged on the second movable arm 42 for cutting the wire after the winding is completed. The aforementioned cutting mechanism can be a pneumatic scissors, and the utility model does not specifically limit it here, as long as it can complete the cutting of the wire harness.

[0034] The following describes the aforementioned first movable arm 41 and second movable arm 42 in detail. The first movable arm 41 has a wire hole extending through its thickness, and the aforementioned clamping assembly is fixedly positioned axially along the wire hole. Specifically, the clamping assembly is fixedly positioned below the wire hole and is used to grip the end of the wire passing through the wire hole from above the first movable arm 41. The wire end is then brought to the winding station via the movement of the motor-screw linear module. The second movable arm 42 has a wire conduit fixed perpendicularly to its side, and a pneumatic shear is fixed perpendicularly to the conduit. The wire is first guided through the conduit, then clamped by the clamping assembly located above the first movable arm 41 and transferred to the winding station to complete the winding process. After the winding process is completed, the servo motor is activated, and the pneumatic shears located above the second movable arm 42 cut the wire. The wire then retracts under the action of the wire feed mechanism, facilitating the next winding process.

[0035] The motor screw linear module described above is described in detail below. The motor screw linear module includes a first motor screw linear module 43, a second motor screw linear module 44, and a third motor screw linear module 45. The first motor screw linear module 43 is fixed on the gantry, the second motor screw linear module 44 is vertically fixed on the first motor screw linear module 43, and the third motor screw linear module 45 is vertically fixed on the second motor screw linear module 44. The movement directions of the first motor screw linear module 43, the second motor screw linear module 44, and the third motor screw linear module 45 are perpendicular to each other, thereby taking into account the position adjustment requirements of the first movable arm 41 and the second movable arm 42 controlled by the servo motor in space.

[0036] The aforementioned motor screw linear module includes a slide rail and a click fixed along the length direction of the slide rail. A movable plate is arranged on the slide rail, and the plate can reciprocate along the length direction of the slide rail. A screw is fixed along the axial direction of the rotating shaft of the aforementioned motor, and the screw is threadedly matched with the movable block fixed on the movable plate.

[0037] In actual application, the wire is fed by the wire feeding mechanism, and then the first movable arm 41 or the second movable arm 42 fixed to the joint control position of the first motor screw linear module 43 and the third motor screw linear module 45 grabs the end of the wire to feed the wire to the winding mechanism 61 and assist in completing the winding process. The first movable arm 41 and the second movable arm 42 are driven by the servo motor to rotate 90 degrees clockwise or counterclockwise around the rotating shaft of the servo motor, and the first motor screw linear module 43 is set based on the height direction of the gantry, so the third motor screw linear module 45 can be controlled to reciprocate vertically, and the third motor screw linear module 45 is fixed to the first motor screw linear module 43 along the horizontal direction of the gantry through the connecting plate 511, so the third motor screw linear module 45 can reciprocate horizontally, thereby completing the position adjustment of the first movable arm 41 and the second movable arm 42.

[0038] Figure 5 The schematic diagram shows the overall structure of the winding spindle three-coordinate mechanism. Figure 5 As shown, the winding spindle three-coordinate mechanism 6 includes a winding mechanism 61 and a position moving mechanism. The aforementioned winding mechanism 61 is movably fixed on the position moving mechanism. The winding mechanism 61 is adjusted to different positions through the position moving mechanism to complete the work of obtaining the sleeve and winding, and can assist in completing the encapsulation process.

[0039] The aforementioned winding mechanism 61 includes a winding spindle 611 and a motor. The winding spindle 611 is coaxially fixed on the aforementioned motor and is driven to rotate by the motor. A groove for fixing a sleeve is provided on the end of the winding spindle 611 facing away from the motor. The aforementioned groove is radially opened along the end of the winding spindle 611 away from the motor, and the sleeve is fixedly embedded in the groove.

[0040] The aforementioned position moving mechanism includes a first position moving mechanism 62, a second position moving mechanism 63 and a third position moving mechanism 64. The aforementioned first position moving mechanism 62 is fixedly arranged on the workbench, the second position moving mechanism 63 is vertically fixed on the first position moving mechanism 62, and the third position moving mechanism 64 is vertically fixed on the second position moving mechanism 63. The first position moving mechanism 62, the second position moving mechanism 63 and the third position moving mechanism 64 are perpendicular to each other and are used to complete the three-way position adjustment of the winding mechanism 61.

[0041] The aforementioned first position moving mechanism 62, second position moving mechanism 63 or third position moving mechanism 64 includes a slide rail fixed on the frame 1, a slider is arranged on the slide rail, a movable plate is fixed on the slider, and a displacement motor is also fixed on the frame 1. A screw rod is coaxially fixed based on the axial direction of the displacement motor. The screw rod remains parallel to the slide rail and is threadedly engaged with the connecting block fixed under the movable plate. The screw rod is driven to rotate by the displacement motor, so that the connecting block moves along the length direction of the first screw rod, driving the movable plate to reciprocate based on the length direction of the first slide rail.

[0042] Through the aforementioned first position moving mechanism 62, second position moving mechanism 63 and third position moving mechanism 64, the spatial three-dimensional position adjustment of the winding mechanism 61 can be completed, and the winding mechanism 61 can be adjusted to different positions to complete the work of obtaining the sleeve and winding, and can assist in completing the glue wrapping process, which is conducive to the automation of the sleeve winding and glue wrapping process, effectively improving the production efficiency of the sleeve winding and glue wrapping, and increasing production capacity.

[0043] Figure 6 The overall structure of the right-angle pressing mechanism is shown schematically. Figure 6As shown, the right-angle pressing mechanism 7 includes a positioning plate 71 arranged based on the winding spindle 611, and the winding spindle 611 passes through the center of the positioning plate 71. A first moving mechanism 72 is arranged on one side of the positioning plate 71 for regulating the reciprocating motion of the pressing block based on the up and down directions of the positioning plate 71. The aforementioned first moving mechanism 72 is fixedly arranged on the second moving mechanism 73, and the lateral reciprocating motion of the aforementioned pressing block is regulated by the second moving mechanism 73, and the signed second moving mechanism 73 is fixedly arranged on the third moving mechanism 74, and the reciprocating motion of the pressing block based on the front and back directions of the winding spindle 611 is regulated by the third moving mechanism 74. Based on the aforementioned first moving mechanism 72, the second moving mechanism 73 and the third moving mechanism 74, the three-way position control of the pressing block is completed, so that it can move freely in three directions, thereby straightening the winding process of the sleeve fixed on the spindle. Figure 7 The diagram shows the coordination between the winding spindle three-coordinate mechanism and the right-angle pressing mechanism.

[0044] The aforementioned first moving mechanism 72, second moving mechanism 73 and third moving mechanism 74 include slide rails, on which are arranged movable blocks that can reciprocate along the length direction of the slide rails, and the movable blocks are driven by cylinders fixed on the movable plates; it is worth noting that in the first moving mechanism, a steering block is fixed on the movable plate, and the pressure block is set on the first moving mechanism through the steering block, wherein the steering block can be an L-shaped part, so that the pressure block on the first moving mechanism arranged on one side of the winding spindle 611 can be pressed toward the sleeve from the upper side or the lower side of the sleeve respectively.

[0045] In addition, the first moving mechanisms 72 located on both sides of the winding main shaft 611 are symmetrical based on the center of the winding main shaft 611, so that the direction of the pressure block set thereon is also symmetrical based on the center of the winding main shaft 611, which is used to complete the right-angle pressing process of different positions of the sleeve. In addition to the first moving mechanism 72, the corresponding second moving mechanism 73 and the third movable plate and other structures are completely symmetrical based on the central axis of the positioning plate 71.

[0046] The pressure blocks set on both sides of the winding spindle 611 are symmetrical based on the center of the winding spindle 611 and are used to straighten the upper and lower sides of the sleeve. The moving mechanism is used to adjust the position of the pressure blocks to adapt to the winding spindle 611 of different sizes, and the pressure blocks are moved to the sleeve position to assist in completing the flying wire bending process.

[0047] Figure 8 The overall structure of the encapsulation mechanism is shown schematically. Figure 9 The schematic diagram shows the main structure of the right side of the rubber encapsulation mechanism. Figure 10 The rear view structure of the right side encapsulation mechanism is shown schematically. Figure 8-10As shown, the gluing mechanism 5 includes a left-side gluing mechanism 5 and a right-side gluing mechanism 5 that are relatively arranged. The aforementioned gluing mechanism 5 includes a movable component 51 fixed to the front side of the frame 1, and a movable plate 52 that can reciprocate in the transverse direction is provided on the movable component 51. A plurality of rollers 53, a cutting component and a feeding fixing component are fixedly provided on the movable plate 52, wherein the cutting component and the feeding fixing component are distributed on the left and right sides of the aforementioned plurality of rollers 53. A tensioning mechanism 56 is also fixedly provided on the movable plate 52, and the tensioning mechanism 56 is fixedly provided between the rollers 53 for adjusting the tension of the tape;

[0048] The aforementioned tensioning mechanism 56 includes a bending piece, which is movably fixed on the movable plate 52 based on its bending part. Rollers 53 are movably fixed at the bending part and one end of the bending piece. The other end of the bending piece is driven up and down by a first cylinder 562 fixed on the movable plate 52, thereby changing the position of the roller located at one end above the bending piece, thereby completing the adjustment of the tensioning force of the tape.

[0049] The following is a detailed description of the fixing method of the first cylinder 562 and the bending member. The first cylinder 562 is fixed to the side of the movable plate 52 facing the movable assembly 51, that is, the first cylinder 562 is fixed to the back side of the movable plate 52. The aforementioned plurality of rollers 53 and the bending member are fixedly provided on the front side of the movable plate 52. The telescopic rod of the aforementioned first cylinder 562 and one end of the bending member are movably fixed by a connecting rod 563. A limiting hole is provided on the movable plate 52 that passes through the thickness direction of the movable plate 52. The limiting hole is a long hole. The connecting rod 563 can reciprocate in the aforementioned limiting hole. The telescopic movement of the first cylinder 562 drives one end of the bending member to change its longitudinal position. Because its bending part is movably fixed on the movable plate 52, the roller 53 located at the other end thereof can change its longitudinal and lateral positions accordingly. To facilitate the return of the bending piece, an elastic component can be fixedly installed at the bending part of the bending piece. By using the connecting rod 563 to push one end of the bending piece, when the connecting rod 563 returns, the return of the bending piece can be regulated by the elastic component.

[0050] The cutting assembly is fixedly arranged on one side of the moving direction of the movable plate 52. The cutting assembly includes a second cylinder 541 fixed vertically and a cutter 542. The cutter 542 is fixedly arranged at the end of the telescopic rod of the second cylinder 541 for completing the cutting of the tape.

[0051] The present invention also includes a feeding assembly, which is fixedly arranged on one side of the movable plate 52 in the direction of movement, just like the aforementioned cutting assembly, and includes a locking mechanism and a movable clamping mechanism, while the aforementioned cutting assembly is fixedly arranged between the locking mechanism and the clamping mechanism. The aforementioned locking mechanism includes a stopper 5711 fixed on the movable plate 52 and a movable block 5712 coaxially arranged with the stopper 5711, so that the movable block 5712 can be located above or below the stopper 5711. The movable block 5712 is driven by a third cylinder 5713 to move it closer to or further away from the stopper 5711, thereby tightening or loosening the tape. The aforementioned third cylinder 5713 is also fixedly arranged on the movable plate 52. The movable clamping mechanism includes a clamping cylinder 5721 and a movable cylinder 5722. The clamping cylinder 5721 is fixed on the connecting block 5723 facing the aforementioned block 5711. The connecting block 5723 is fixedly connected to the end of the telescopic rod of the movable cylinder 5722. Under the action of the movable cylinder 5722, the clamping cylinder 5721 fixed on the aforementioned connecting block 5723 can approach or move away from the block 5711. During the feeding process, the locking mechanism first locks the end of the tape. Driven by the movable cylinder 5722, the clamping cylinder 5721 approaches the stop block 5711, and the clamping cylinder 5721 clamps the end of the tape. At this time, the third cylinder 5713 drives the movable block 5712 to move downward. After loosening the tape, the clamping cylinder 5721, driven by the movable cylinder 5722, pulls out the end of the tape to complete the feeding process; further, when the tape needs to be cut, after the clamping cylinder clamps the end of the tape, the movable block 5712 moves upward under the action of the third cylinder 5713, and is in close contact with the stop block 5711 to complete the locking of the tape, and then the cutting mechanism completes the cutting of the tape.

[0052] It also includes a tensioning assembly 58, which is arranged between the aforementioned cutting assembly and the locking mechanism. The tensioning assembly 58 includes a fourth cylinder 581 fixed vertically on the movable plate 52, and a tensioning wheel is fixedly provided at the end of the movable rod of the fourth cylinder 581. The fourth cylinder 581 drives the tensioning wheel to move close to or away from the tape. When the tensioning wheel is in a position close to the tape, the tensioning wheel adjusts the tension of the tape to facilitate the cutting process or the encapsulation process.

[0053] The movable component 51 includes a connecting plate 511 fixed to the front side of the workbench, a slide rail 512 is fixedly provided on the connecting plate 511 along the length direction of the connecting plate 511, and a slider matching the slide rail 512 is fixedly provided on the rear side of the movable plate 52. The movable plate 52 is movably fixed to the slide rail 512 by the slider. The movable plate 52 can be driven by a cylinder fixed on the workbench to reciprocate along the length direction of the guide rail, thereby completing the adjustment of the lateral position of the movable plate 52 to facilitate the encapsulation process.

[0054] The aforementioned loading and fixing assembly is fixed to the side of the movable plate 52, facing away from the cutting assembly. It includes a plate 551 and limiting posts 552 fixed between the plates 551. Limiting blocks 553 are mounted on the limiting posts 552, securing the roll of adhesive tape. During the actual encapsulation process, the loading and fixing assembly is used to secure the tape. The ends of the tape are sequentially wound around rollers 53, which tension and transport the tape. The ends are then placed in a locking mechanism. A movable clamping mechanism then grips the ends of the tape to assist in completing the encapsulation process. After encapsulation is complete, the tape is cut by the cutting mechanism. The entire process is fully automated, requiring no additional human assistance. In addition, by setting up a completely symmetrical rubber wrapping mechanism 5 on the left and right, the rubber wrapping process of the sleeve can be carried out multiple times, and the continuous rubber wrapping process can be ensured. That is, when the tape on one side is used up, the rubber wrapping mechanism 5 on the other side can be used in time to continue the rubber wrapping process. At this time, the used tape can be replenished, avoiding the stop of the production process due to the need to replenish materials, thereby improving production efficiency.
