Implementation

[0028] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0029] As used herein, the terms “parallel,” “perpendicular,” etc., are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0030] like Figures 1-11 As shown, a feeding device for wire harness production includes a feeding trough. The feeding end of the feeding trough is equipped with a feeding mechanism for adding plastic sleeves 01 into the trough. The middle of the feeding trough is equipped with a rejection mechanism for removing plastic sleeves 01 that do not meet preset posture requirements. The unloading end of the feeding trough is equipped with an assembly mechanism for inserting and assembling plastic sleeves 01 with wire harnesses 02. The plastic sleeve 01 is composed of an elastic plastic tube, which includes a corrugated tube body and a straight tube section. The outer diameter of the corrugated tube body is larger than the outer diameter of the straight tube section. The cross-section of the feeding trough cavity perpendicular to the trough length direction is an inverted "U" shape. The trough cavity cross-section includes upper and lower arranged regions A and B. The size of region A matches the size of the corrugated tube body, and the size of region B matches the size of the straight tube section. The preset posture is that the length direction of the plastic sleeve 01 is consistent with the depth direction of the feeding trough, the corrugated tube body is located in region A, and the straight tube section is located in region B. The aforementioned feeding device can reliably and automatically feed the plastic sleeve 01 and assemble it with the wire harness 02, thereby improving production efficiency.

[0031] A further embodiment is as follows: The feeding mechanism includes a horizontally arranged feeding barrel 20. Feeding plates are provided on the inner wall of the feeding barrel 20, spaced apart circumferentially. One end of a feeding chute is inserted into the feeding barrel 20. The feeding barrel 20 is mounted on a feeding support, which is equipped with a barrel drive mechanism for rotating the feeding barrel 20. The feeding support includes two opposing support shafts 81, rotatably mounted on a frame. Support wheels 82 are provided at both ends of the support shafts 81, supporting both ends of the barrel. The barrel drive mechanism includes a barrel drive motor, which is connected to the support shafts 81. The barrel drive motor can be connected to both support shafts 81 separately, or to one support shaft 81.

[0032] The preferred embodiment is as follows: an annular groove is provided on the outer surface of the support wheel 82, and a rubber ring 83 is provided inside the annular groove, with a portion of the rubber ring 83 protruding from the outer surface of the support wheel 82. The annular groove is spaced apart along the length of the centerline of the support wheel 82. The part on the outer wall 22 of the feeding barrel 20 corresponding to the support wheel 82 is designated as the support part, and grooves are provided on the outer surface of the support part. The grooves and the rubber ring 83 are mainly designed to increase the friction between the roller and the drive wheel, preventing slippage during the rotation of the feeding barrel 20.

[0033] like Figure 3 , 4 As shown in Figure 5, a baffle 15 is provided on the conveying trough 10 to prevent the plastic sleeve 01 from being moved out of the feeding hopper 20. Specifically, the baffle 15 can be fixedly assembled with the conveying trough 10. A ring cover is provided at the opening of the feeding hopper 20, and the baffle 15 is arranged corresponding to the material opening in the middle of the ring cover. The shape of the baffle 15 is set to match the shape of the opening of the feeding hopper 20, specifically, it can be circular.

[0034] In specific operation, the feeding hopper 20 can be arranged at an angle or horizontally. One embodiment is that the feeding hopper 20 is arranged at an angle on the feeding support, with the height of one end of the feeding hopper opening greater than the height of the other end, such as... Figure 11 As shown. This method is adapted for feeding hoppers 20 with single-layer cylindrical wall structures, facilitating the removal of recycled plastic shells and refeeding within the single-layer feeding hopper 20. Preferably, the method used is as follows... Figure 4The scheme shown is implemented in such a way that the feeding hopper 20 is arranged horizontally. The cylinder wall of the feeding hopper 20 includes an inner cylinder wall 21 and an outer cylinder wall 22. The inner and outer cylinders are composed of concentrically arranged tubes. The inner diameter of the inner cylinder wall 21 gradually decreases along the direction a, which is the conveying direction of the conveying trough 10. The two ends of the inner cylinder wall 21 are respectively connected to the bottom and the opening of the cylinder with ring covers. The feeding plate is fixedly set on the inner cylinder wall 21. The feeding plate is composed of folded plates, including a first plate part 23 and a second plate part 24. The first plate part 23 and the second plate part 24 are arranged sequentially and at an angle to each other. The second plate part 24 is arranged closer to the bottom of the feeding hopper 20 than the first plate part 23. The bottom of the feeding hopper 20 is fixedly connected to the end edge of the second plate part 24. The first plate part 23 is fixedly set on the inner cylinder wall 21 with ring covers at the bottom and the opening of the cylinder 22. The inner diameter of the inner cylinder wall 21 gradually decreases along the direction a, which is the conveying direction of the conveying trough 10. The two ends of the inner cylinder wall 21 are respectively connected to the bottom and the opening of the cylinder 22. The feeding plate is fixedly set on the inner cylinder wall 21 with ring covers at ... The feeding plate is arranged with its plane coinciding with the center line of the feeding hopper 20. The state when the first plate portion 23 of the feeding plate is horizontally arranged is denoted as state A. When the feeding plate flips from sideways to topways in state A, the second plate portion 24 is located above the upper surface of the first plate portion 23. The feed section at the feeding end of the feeding trough is denoted as the feeding section. A cantilevered guide plate 11 extends obliquely upwards and outwards from the feeding trough 10 at one side of the feeding section's opening. A downwardly bent arc-shaped baffle plate 12 is provided on the outer edge of the cantilevered guide plate 11. The arc of the arc-shaped baffle plate 12 matches the included angle α, which is the angle between the first plate portion 23 and the guide plate 11 in state A. When the first plate portion 23 rotates outside the arc-shaped baffle plate 12, the edge of the first plate portion 23 and the outer surface of the arc-shaped baffle plate 12 are arranged with a gap. This gap size is designed so that the plastic sleeve 01 cannot pass through the gap. The curvature of the arc-shaped baffle 12 matches the angle between the first plate body 23 and the guide plate 11 in state A. Simply put, the curvature of the projection of the arc-shaped baffle onto the bottom of the feeding hopper 20 is consistent with the angle α, where angle α is the projection of the first plate body 23 and the guide plate 11 onto the bottom of the feeding hopper 20 in state A. The inner cylinder wall 21 has a mesh structure, and the middle of the outer cylinder wall 22 and the middle of the bottom plate also use mesh structures. Specifically, the bottom plate of the feeding hopper 20 is composed of an annular mesh plate, with the feeding port 27 formed in the middle of the annular mesh plate.

[0035] A feeding port 27 is provided at the bottom of the feeding hopper 20, and the feeding port 27 is connected to the feeding mechanism. The feeding device includes a feeding pipe 71, one end of which is rotatably assembled to the bottom of the feeding hopper 20 or inserted loosely at the feeding port 27, and the other end of the feeding pipe 71 is provided with a hopper 70 connected thereto. A push plate is also provided inside the feeding pipe 71, which is assembled to one end of a push tube. The push tube and the feeding pipe 71 are slidably assembled, and the other end of the push tube is connected to a push rod 72 that pushes it to move. A more preferred embodiment is that the feeding pipe 71 is connected to a blower, which blows air from the plastic shell inside the feeding pipe 71 into the feeding hopper 20. This method is more convenient to operate.

[0036] A material-removing section 13 is provided on the conveying trough 10. One side of the trough wall forming area A on the material-removing section 13 is left empty, and air distribution vents 14 are provided on the other side of the trough wall forming area A. The air distribution vents 14 are arranged at intervals along the length of the material-removing section 13, and the air outlet direction of the air distribution vents 14 points towards the empty side. The material-removing mechanism includes air distribution boxes 16 arranged corresponding to the material-removing section 13. The air distribution boxes 16 are connected to each air distribution vent 14 and are connected to a blower through an air pipe. The material-removing section 13 is located between the material distribution section and the material-blocking member 15. The material-removing section 13 and the material distribution section are located inside the feeding hopper 20. The material-blocking member 15 is provided with mounting holes for assembling the air pipe. The blower and the aforementioned air-blowing device can be the same component or different components. The corresponding feeding section and material-removing section 13 are arranged on the first plate body 23. A feeding assembly 30 is provided at the other end of the feeding trough. The assembly mechanism includes a pick-up needle, a transfer needle, a first transfer assembly, and a second transfer assembly.

[0037] The aforementioned material-removing section 13, conical inner cylinder, and second plate section 24 ensure that plastic sleeves 01 that do not conform to the desired posture can be reliably recycled back into the feeding hopper 20 for refeeding. Simultaneously, even when there are few plastic sleeves 01 in the feeding hopper 20, they can be reliably and quickly fed onto the conveying trough 10 for transport. This solves the problem of low utilization rate and efficiency of plastic sleeves 01 when material is scarce, avoiding situations where reliable retrieval is impossible when there are very few plastic sleeves 01 in the feeding hopper 20. The aforementioned material-removing device ensures that plastic sleeves 01 that do not conform to the preset posture can be removed and reliably recycled, while plastic sleeves 01 that conform to the preset posture can be reliably retained because the straight pipe section is reliably clamped by area B. The structure is simple and the implementation cost is low. The feeding device eliminates the need to stop the machine and remove the feeding hopper 20 to replenish plastic shells; simply pour new plastic shells into the hopper 70, making operation more convenient and time-saving. The end of the conveying trough 10 can be set to stop at the junction of the first and second plate sections. The upper surface of the slot wall at the vacancy is inclined, with a greater height on the side closer to the slot cavity. This facilitates the rejection and reuse of plastic sleeves 01 that do not conform to the preset posture.

[0038] The present invention also provides a process for assembling a plastic sleeve onto a wire harness, comprising arranging and conveying the plastic sleeve 01, arranging and picking up the plastic sleeve 01 corresponding to the arranged and conveyed plastic sleeve 01, adjusting the arrangement of the picking up needle 41 and the transfer needle 42 in a corresponding and sequential manner, using a first transfer assembly 50 to transfer the plastic sleeve 01 fitted on the picking needle 41 to the transfer needle 42, adjusting the arrangement of the transfer needle 42 in a sequential manner with the assembly end of the wire harness 02 to which the plastic sleeve 01 is to be assembled, and using a second transfer assembly 60 to transfer the plastic sleeve 01 fitted on the transfer needle 42 to the assembly end of the wire harness 02.

[0039] A further solution involves setting a material-taking section on the material-taking needle 41, with the plastic sleeve 01 fitted onto the material-taking section, and setting a material-transferring section on the material-transferring needle 42, with the plastic sleeve 01 fitted onto the material-transferring section. The diameter of the material-transferring section is set to be larger than the diameter of the material-taking section. This makes it easier to fit the plastic sleeve 01 and the end of the wire harness 02.

[0040] Plastic sleeves 01 are conveyed via a horizontally arranged conveyor trough 10. The conveyor trough 10 is mounted on a linear vibrator 17 (vibrating plate base). A picking needle 41 is suspended on a picking seat, positioned corresponding to the unloading end of the conveyor trough 10. The plastic sleeves 01 conveyed on the conveyor trough 10 are picked up by adjusting the downward movement of the picking needle 41. The conveyor trough 10 can be tilted so that the upper end of the inlet is higher than the unloading end. The picking seat is slidably mounted vertically on the frame and is connected to a picking adjustment cylinder that adjusts its height.

[0041] A feeding assembly 30 is provided at the unloading end of the conveying trough 10. The feeding assembly 30 includes a baffle plate 33 that prevents the plastic sleeve 01 from moving out along the conveying direction of the conveying trough 10. A first material support mounting member 32 and a second material support mounting member are arranged at relatively intervals on the inner side of the baffle plate 33. A first material support member 31 and a second material support member 31 are respectively provided on the inner side plate of the first material support mounting member 32 and the second material support mounting member. The first material support member 31 and the second material support member 31 can be switched between a first state and a second state by adjusting the state of the first material support member 31 and the second material support member 31. The first state is: the first material support member 31 and the second material support member 31 support the plastic sleeve 01; the second state is: the first material support member 31 and the second material support member 31 avoid the movement of the plastic sleeve 01.

[0042] Specifically, there are two implementation methods. The first method is to use a material support plate to form a first material support 31 and a second material support 31. The ends of the first material support 31 and the second material support 31 that are far apart from each other are respectively assembled by a hinge shaft and a coiled spring. The adjacent ends of the first material support 31 and the second material support 31 are arranged in a cantilevered manner with intervals. In the first state, the upper surface of the cantilevered end of the material support plate is flush with the shoulder surface (the platform formed at the junction of area A and area B) in the conveying trough 10 and extends to receive a plastic sleeve 01 at the very end of the conveying trough 10. In the second state, the picking needle 41 moves downward and inserts into the plastic shell and pushes the plastic shell against the first material support 31 and the second material support 31 to flip it over, so that the first material support 31 and the second material support 31 avoid the removal of the plastic sleeve 01. Secondly, the first and second material support components 31 are constructed using elastic plastic sheets. The ends of the first and second material support components 31 are fixedly assembled away from each other. The adjacent ends of the first and second material support components 31 are arranged in a cantilevered, spaced-apart configuration. In the first state, the upper surface of the cantilevered end of the elastic plastic sheet is flush with the inner shoulder surface of the conveying trough 10 and extends along the trough, receiving the plastic sleeve 01 at the very end of the conveyed material within the conveying trough 10. In the second state, the picking needle 41 moves downwards, inserts into the plastic shell, and pushes the plastic shell against the first and second material support components 31, causing elastic bending. This allows the first and second material support components 31 to avoid the removal of the plastic sleeve 01. This configuration can be selected according to specific requirements.

[0043] A rotating shaft 43 is installed below the unloading end of the conveying trough 10. A rotating needle 42 is mounted on the rotating shaft 43. The rotating shaft 43 is adjusted to rotate so that the rotating needle 42 is vertical and opposite to the picking needle 41, or horizontal and corresponding to the assembly end of the wire harness 02 of the horizontally shaped plastic sleeve 01 to be assembled. The wire harness 02 to be assembled can be assembled manually or using an automated conveyor line. The choice depends on the specific situation. The rotating shaft 43 can be connected to a servo motor.

[0044] A first material transfer assembly 50 is composed of A1 transfer components 51 and A2 transfer components arranged opposite to each other. A1 and A2 transfer components are movably mounted on a first material transfer seat. A1 and A2 transfer components are connected to an A1 material transfer adjustment assembly, which adjusts the A1 and A2 transfer components to move closer or further apart. The first material transfer seat is connected to an A2 material transfer adjustment assembly, which adjusts the first material transfer seat to move along the length of the picking needle 41. The A1 and A2 transfer components have the same structure. The A1 transfer component 51 includes an A transfer plate 52 arranged horizontally on the plate surface and an A correction block 53 located below the A transfer plate 52. The A transfer plate 52 is provided with an A-gap portion, which is used to push the plastic sleeve 01 to move on the picking needle 41. The A correction block 53 is provided with a semi-conical A-conical groove, the size of which gradually increases from top to bottom. The A-conical groove is used to align the picking needle 41 and the transfer needle 42. In specific operation, the A1 and A2 transfer components can be slidably assembled on the first transfer seat in a horizontal direction perpendicular to the a direction. The A1 transfer adjustment assembly can be composed of A1 cylinders connected to the A1 and A2 transfer components respectively. The first transfer seat is slidably mounted on the frame in a vertical direction. The A2 transfer adjustment assembly can be composed of A2 cylinders connected to the first transfer seat. The specific operation process is as follows: Figure 7 , 8 As shown. The first transfer assembly of the above structure forms an A-gap for accommodating the material-taking section through two A-gap portions, allowing the two A-transfer plates 52 to clamp (empty clamp) the material-taking section. Thus, when the A-transfer plates 52 move along the length of the material-taking needle, they push the plastic sleeve 10 onto the transfer needle. The two A-conical grooves form a conical A-correction cavity, ensuring that the needle tip of the material-taking needle and the needle tip of the transfer needle can be reliably aligned, guaranteeing reliable transfer of the plastic sleeve between the material-taking needle and the transfer needle.

[0045] A second material transfer assembly 60 is formed by two relatively arranged transfer components, B1 61 and B2. The transfer components 61 and B2 are movably mounted on a second material transfer seat. The transfer components 61 and B2 are connected to a B1 material transfer adjustment assembly, which adjusts the transfer components 61 and B2 to move closer together or further apart. The second material transfer seat is connected to the B2 material transfer adjustment assembly, which adjusts the second material transfer seat along a horizontal direction perpendicular to the material picking needle 41 (the conveying direction of the conveying trough 10). (Direction) Movement: The B1 and B2 transfer components have the same structure. The B1 transfer component 61 includes a vertically arranged B transfer plate 62 and a B correction block 63 located outside the B transfer plate 62. The B transfer plate 62 has a B gap, which is used to push the plastic sleeve 01 to move on the transfer needle 42. The B correction block 63 has a semi-conical B conical groove, the size of which gradually increases along the a direction. The B conical groove is used to align the end of the wire harness 02 with the transfer needle 42. In specific operation, the B1 and B2 transfer components can be slidably assembled on the second transfer seat in a horizontal direction perpendicular to the a direction. The B1 transfer adjustment assembly can be composed of B1 cylinders connected to the B1 and B2 transfer components respectively. The second transfer seat is slidably mounted on the frame along the a direction. The B2 transfer adjustment assembly can be composed of B2 cylinders connected to the second transfer seat. Figure 9 As shown, the specific operation of the second transfer assembly 60 is similar to that of the first transfer component. A plastic sleeve 01 is added to the feed end of the conveying trough 10 via a rotating feeding bucket 20. In the above-described second transfer assembly, two B-shaped gaps form a B-shaped cavity to accommodate the transfer section, allowing the two B-shaped transfer plates 62 to clamp the transfer section. Thus, when the B-shaped transfer plates 52 move along the conveying direction of the conveying trough, they push the plastic sleeve 10 onto the wire harness. Two B-shaped conical grooves form a conical B-shaped correction cavity, guiding the exposed wire core at the end of the wire harness, ensuring a reliable correspondence between the exposed wire core and the tip of the transfer needle. This allows the plastic sleeve to be reliably transferred from the transfer needle onto the wire harness, improving the reliability of the sleeve application.

[0046] In summary, by adopting the above-described solution of the present invention, the reliability and production efficiency of the installation of the plastic sleeve 01 and the wire harness 02 can be effectively improved. Components and structures not described in detail above can be implemented with reference to existing wire harness production equipment.

[0047] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
