Abstract
Description
Technical Field
[0001] The utility model relates to a wire end-twisting device, in particular to a wire end-twisting device for a long-short wire structure harness. Background Art
[0002] A twisted wire harness is a wire harness formed by twisting two or more wires. During the manufacturing process, terminals need to be installed at both ends of the wires (generally known as the terminal processing), and then the multiple wires are twisted to form a twisted wire harness.
[0003] Currently, some twisted harnesses require the ends of multiple wires to be staggered, creating a long-short wire structure to facilitate insertion into a specific plastic housing. This long-short wire structure refers to the lengths of the untwisted portions at each end of the wires, not the overall lengths of the wires.
[0004] However, due to the misalignment of the ends of multiple wires, the existing terminal and stranding equipment is unable to terminate the wire harness of this structure. Therefore, during production, terminal and stranding equipment need to be equipped separately. After the terminal equipment completes the terminal process at both ends of the wires, some wires are pulled manually or with wire pulling equipment to cause multiple wires to be misaligned, and then the multiple wires are placed in the stranding equipment for stranding. This method has low production efficiency, and multiple devices require a large space. Utility Model Content
[0005] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to design a terminal and stranding equipment for long and short wire structure harnesses, which can perform terminal and stranding processes on both ends of the long and short wire structure harnesses, thereby improving production efficiency and reducing the space occupied by the equipment.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a terminal and stranding equipment for a long and short wire structure harness, comprising: a wire feeding mechanism, a first terminal station, a stripping and shearing mechanism, a wire pulling mechanism, a wire shifting mechanism, a second terminal station and a wire stranding mechanism, wherein the wire feeding range of the wire feeding mechanism covers the first terminal station and the stripping and shearing mechanism, the stripping and shearing position of the stripping and shearing mechanism is opposite to the wire pulling position of the wire pulling mechanism in the front-to-back direction, and the wire feeding range of the wire shifting mechanism covers the stripping and shearing mechanism, the second terminal station and the wire stranding mechanism ; The end-stranding wire equipment also includes: a short wire stretching mechanism, the short wire stretching position of the short wire stretching mechanism is opposite to the wire pulling position of the wire pulling mechanism in the front-to-back direction, the short wire stretching mechanism includes: a first short wire stretching chuck, a second short wire stretching chuck and a short wire stretching longitudinal movement device, the first short wire stretching chuck and the second short wire stretching chuck are both arranged on the short wire stretching longitudinal movement device, and the wire clamping position of the first short wire stretching chuck and the wire clamping position of the second short wire stretching chuck are staggered in the left-right direction.
[0007] Furthermore, the first elongated short wire chuck includes: a first pneumatic finger, a first upper clamp block and a first lower clamp block, the first upper clamp block and the first lower clamp block are both arranged on the first pneumatic finger and are arranged opposite to each other up and down, the first upper clamp block and the first lower clamp block are both provided with a clearance groove and the clearance grooves of the two are arranged opposite to each other up and down; the second elongated short wire chuck includes: a second pneumatic finger, a second upper clamp block and a second lower clamp block, the second upper clamp block and the second lower clamp block are both arranged on the second pneumatic finger and are arranged opposite to each other up and down, the two upper clamp blocks and the second lower clamp block are both provided with a clearance groove and the clearance grooves of the two are arranged opposite to each other up and down. Among them, since the first elongated short wire chuck and the second elongated short wire chuck are both provided with a clearance position, it is possible to avoid the elongated short wire chuck from accidentally clamping another wire when processing multiple groups of wire harnesses, thereby ensuring that the multiple wires of the wire harness are effectively pulled into a front-to-back dislocated structure, that is, a long-short wire structure.
[0008] Furthermore, the wire pulling mechanism includes a wire pulling longitudinal displacement device and a wire pulling clamp. The wire pulling clamp is mounted on the wire pulling longitudinal displacement device, and the wire clamping position of the wire pulling clamp is aligned with the short wire extension position of the short wire extension mechanism in the front-to-back direction. The wire pulling clamp is used not only to pull the wire to a predetermined length but also to cooperate with a second short wire extension clamp to bend a second wire so that the B ends of the wires are aligned.
[0009] Furthermore, the short-line stretching mechanism further includes a short-line stretching transverse movement device, wherein the first short-line stretching clamp and the second short-line stretching clamp are both mounted on the short-line stretching transverse movement device, and the short-line stretching transverse movement device is mounted on the short-line stretching longitudinal movement device. The short-line stretching transverse movement device can drive the first short-line stretching clamp and the second short-line stretching clamp to move in the left-right direction, thereby avoiding interference when the wire pulling clamp moves in the front-back direction to pull the wire.
[0010] Furthermore, the wire feeding mechanism includes: a wire feeding wheel assembly, a wire feeding chuck, a wire feeding longitudinal displacement device, and a wire feeding transverse displacement device. The wire feeding wheel assembly is located in front of the wire feeding chuck, the wire feeding wheel assembly and the wire feeding chuck are both mounted on the wire feeding longitudinal displacement device, and the wire feeding longitudinal displacement device is mounted on the wire feeding transverse displacement device. The provision of the wire feeding wheel assembly can guide the wires and improve the smoothness of wire feeding.
[0011] Furthermore, the first terminal crimping station includes: a first terminal crimping machine, a first waterproof plugging machine, and a first visual inspection machine, wherein the first terminal crimping machine, the first waterproof plugging machine, and the first visual inspection machine are arranged in sequence along the left-right direction, and the first visual inspection machine is located closest to the stripping and shearing mechanism; the second terminal crimping station includes: a second terminal crimping machine, a second waterproof plugging machine, and a second visual inspection machine, wherein the second terminal crimping machine, the second waterproof plugging machine, and the second visual inspection machine are arranged in sequence along the left-right direction, and the second visual inspection machine is located closest to the stripping and shearing mechanism. The provision of the first waterproof plugging machine and the second waterproof plugging machine allows waterproof plugs to be installed at both ends of the wire, thereby providing a waterproof effect on both ends of the wire.
[0012] Furthermore, the stripping and shearing mechanism includes: an upper stripping and shearing head, a lower stripping and shearing head, a stripping and shearing lifting device, and a material pipe. The upper stripping and shearing head is arranged on the stripping and shearing lifting device, and the upper stripping and shearing head, the lower stripping and shearing head, and the material pipe are arranged in order from top to bottom. The material pipe can collect the cut wire sheath to prevent the wire sheath from being scattered.
[0013] Furthermore, the wire moving mechanism includes: a wire feeding robot at the B end, a wire feeding robot at the A end, a variable pitch robot at the B end, a variable pitch robot at the A end and a wire moving longitudinal movement device. The wire feeding robot at the B end and the wire feeding robot at the A end are arranged relative to each other front and back, and the variable pitch robot at the B end and the variable pitch robot at the A end are arranged relative to each other front and back. The wire feeding robot at the A end and the variable pitch robot at the A end are both arranged in the wire moving longitudinal movement device. The wire feeding range of the variable pitch robot at the B end covers the wire feeding robot at the B end and the wire twisting mechanism, and the wire feeding range of the variable pitch robot at the A end covers the wire feeding robot at the A end and the wire twisting mechanism. Among them, when terminalizing, minimizing the distance between multiple wires is conducive to using a small terminal machine to perform the terminalizing process on multiple wires at the same time. When twisting the wires, the distance between the multiple wires needs to be increased to provide clamping and rotation space. Since the wire moving mechanism is provided with a B-end variable pitch manipulator and an A-end variable pitch manipulator, the distance between the multiple wires can be increased before twisting the wires to cooperate with the twisting process; in addition, since the wire moving mechanism is provided with a wire longitudinal moving device, it can adapt to conductive wires of different lengths.
[0014] Furthermore, the B-end variable-pitch manipulator includes: a variable-pitch clamp, a recovery clamp, and a transfer and transverse movement device. The variable-pitch clamp and recovery clamp are both located in the transfer and transverse movement device. The variable-pitch clamp includes: a first variable-pitch clamp, a second variable-pitch clamp, and a variable-pitch transverse movement device. The clamping position of the first variable-pitch clamp and the clamping position of the second variable-pitch clamp are staggered in the left-right direction. The second variable-pitch clamp is located in the variable-pitch transverse movement device. The recovery clamp includes: a recovery clamp and a longitudinal movement recovery device. The recovery clamp is located in the longitudinal movement recovery device. The structure of the A-end variable-pitch manipulator is the same as that of the B-end variable-pitch manipulator. Since both the B-end variable-pitch manipulator and the A-end variable-pitch manipulator are equipped with a recovery clamp, the second wire can be straightened before stranding to facilitate the stranding process.
[0015] Furthermore, the stranding mechanism includes: a B-end stranding machine, an A-end stranding machine, and a stranding longitudinal displacement device. The B-end stranding machine and the A-end stranding machine are arranged in a front-to-rear relationship, and the A-end stranding machine is mounted on the stranding longitudinal displacement device. The stranding mechanism is equipped with the stranding longitudinal displacement device, so it can adapt to different wire lengths.
[0016] After adopting the above technical solution, the beneficial effect is: after completing the end-end process of multiple wires A ends, the end-end twisting equipment of the utility model can use the cooperation of the wire pulling mechanism and the short wire stretching mechanism to pull multiple wires into a staggered long-short wire structure between the two end-end processes, and make the B ends of multiple wires flush, thereby realizing the end-end process of multiple wires B ends, overcoming the problem that traditional end-end twisting equipment cannot perform the end-end process on both ends of the long-short wire structure harness, improving production efficiency, and reducing the space occupied by the production harness.

[0030] The technical solution of the present invention is further described below by way of embodiments:
[0031] The utility model provides a long and short wire structure wire harness end-twisting device, combined with Figures 1 to 3 As shown, the terminal and stranding equipment includes: a chassis 1, a wire feeding mechanism 2, a first terminal station 3, a stripping and shearing mechanism 4, a wire pulling mechanism 5, a short wire stretching mechanism 6, a wire moving mechanism 7, a second terminal station 8 and a wire stranding mechanism 9. The wire feeding mechanism 2, the first terminal station 3, the stripping and shearing mechanism 4, the wire pulling mechanism 5, the short wire stretching mechanism 6, the wire moving mechanism 7, the second terminal station 8 and the wire stranding mechanism 9 are all located inside the chassis 1. The wire feeding range of the wire feeding mechanism 2 covers the first terminal station 3 and the stripping and shearing mechanism 4. The stripping and shearing mechanism 4 is located between the first terminal station 3 and the second terminal station 8. The stripping and shearing position of the stripping and shearing mechanism 4, the wire pulling position of the wire pulling mechanism 5, and the short wire stretching position of the short wire stretching mechanism 6 are opposite in the front-to-back direction. The wire feeding range of the wire moving mechanism 7 covers the stripping and shearing mechanism 4, the second terminal station 8 and the wire stranding mechanism 9.
[0032] The following takes a wire harness including two electric wires as an example to illustrate the working principle of the terminal twisting equipment: when the terminal twisting equipment is working, first, the two electric wires are fed into the chassis 1 from the feeding device and clamped by the wire feeding mechanism 2, the wire feeding mechanism 2 transfers the two electric wires to the stripping and shearing position of the stripping and shearing mechanism 4, the wire feeding mechanism 2 cooperates with the stripping and shearing mechanism 4 to strip the A end of each electric wire, and after the stripping is completed, the wire feeding mechanism 2 transfers the two electric wires to the first terminal twisting station 3 to perform the terminal twisting process on the A end of each electric wire; then the wire feeding mechanism 2 is used to transfer the two electric wires to the stripping and shearing position of the stripping and shearing mechanism 4 and release the electric wires, and the wire pulling mechanism 5 is used to clamp and pull the electric wires backward until each electric wire reaches a predetermined length and the two electric wires are placed on the wire moving mechanism 7, the stripping and shearing mechanism 4 cuts each electric wire to form a B end, and the wire pulling mechanism 5 cooperates with the stripping and shearing mechanism 4 to twist each electric wire The B end of the wires is stripped; then the wire pulling mechanism 5 releases the two wires, and the short wire stretching mechanism 6 clamps and pulls the first wire backward, so that the two wires are dislocated front and back, and the wire pulling mechanism 5 re-clamps the two wires, and then uses the short wire stretching mechanism 6 to pull the second wire backward in front of the wire pulling mechanism 5, so that the second wire is bent due to being squeezed, and the B ends of the two wires are flush front and back. At this time, the wire moving mechanism 7 clamps the A end and B end of the two wires, and the wire pulling mechanism 5 and the short wire stretching mechanism 6 release the two wires; then the wire moving mechanism 7 is used to transfer the two wires to the second terminal station 8 to perform the terminal process on the B end of each wire; finally, the wire moving mechanism 7 is used to restore the second wire to a straight state, and the two wires are transferred to the stranding mechanism 9, and the stranding mechanism 9 is used to strand the two wires, thereby forming a set of wire harnesses.
[0033] Among them, the stripping and wire cutting position of the stripping and cutting mechanism 4, the wire pulling position of the wire pulling mechanism 5, and the short wire stretching position of the short wire stretching mechanism 6 all refer to the positions for operating the wires, that is, the stripping and wire cutting position and the clamping position, and the clamping position includes the set of all position points along the front-to-back direction; in addition, facing along the front-to-back direction means that the projections of the two in the front-to-back direction at least partially overlap.
[0034] It is worth mentioning that in this embodiment, the end-twisting equipment can realize the end-twisting process of two groups of wire harnesses, while in other embodiments, the end-twisting equipment can also realize the end-twisting process of one or more groups of wire harnesses.

A portion of the wire pulling mechanism 5, a portion of the wire moving mechanism 7, and a portion of the wire twisting mechanism 9 are all located in the splicing box 12. When using the end-breaking and wire twisting equipment, the working range of the wire pulling mechanism 5, the wire moving mechanism 7, and the wire twisting mechanism 9 in the front-to-back direction can be selected according to the actual length of the wire harness, and splicing boxes 12 of corresponding lengths can be spliced to accommodate different wire lengths.

[0052] It is worth mentioning that, although the rotating device 912 is a rotating cylinder in this embodiment, in other embodiments, the rotating device 912 may also be a device such as a motor that can drive a component to rotate.

[0054] It is worth mentioning that the chuck of the present invention can adopt a structure in which a pneumatic finger is connected to two clamping blocks, and the pneumatic finger controls the two clamping blocks to move closer or farther from each other; it can also adopt a structure in which a linear cylinder is connected to one movable clamping block and the other clamping block is fixed, and the linear cylinder controls the movable clamping block to move closer or farther from the fixed clamping block; it can also adopt a structure in which a linear cylinder, a toggle are connected to two clamping blocks, and the linear cylinder drives the toggle to move, causing the ends of the two clamping blocks to move closer or farther from each other. However, the chuck of the present invention is not limited to the above structures; any structure that can clamp wires can be used.
