Description

Technical Field

[0001] The invention relates to the technical field of double-head terminal machines, and in particular to a fully automatic multifunctional double-head terminal machine. Background Art

[0002] A double-head terminal machine is a device used for wire processing. It can perform terminal crimping operations on both ends of the wire at the same time, greatly improving production efficiency. Double-head terminal machines usually have multiple functions. In addition to the basic double-end crimping terminal function, they also often have wire cutting, stripping, half stripping, twisting and other functions. Multiple processes can be completed on one device, reducing equipment investment and production space, and improving the integration and automation of production.

[0003] The patent application document with publication number CN118712840A discloses a double-head terminal crimping machine for wire harnesses, which clamps and limits the wire harness in the cutting mechanism through a clamping and stretching assembly. The cutting mechanism is provided with a shifting assembly to drive the clamping and stretching assembly to move back and forth. The clamping and stretching assembly reciprocates the wire harness in the cutting mechanism and the crimping mechanism. The cut wire harness is transmitted to two sets of crimping mechanisms, so that the crimping operation can be completed synchronously at both ends of the wire harness, further improving the efficiency of preparing the wire harness.

[0004] In the patent application document with announcement number CN222082093U, a wire harness transport device for a double-head fully automatic terminal machine is disclosed. The distance between the first transport mechanism and the second transport mechanism can be adjusted according to the thickness of the wire harness through a spring, and the first transport mechanism and the second transport mechanism can clamp the wire harness. When the first transport mechanism moves, the slider slides along the slide groove. The movement trajectory of the first transport mechanism can be limited by the slider and the slide groove, and the limit ring can further prevent the wire harness from being separated from the first transport mechanism and the second transport mechanism. The output shaft of the motor can drive the transport roller to rotate, thereby transporting the wire harness, solving the problem of only being able to push wire harnesses of the same thickness.

[0005] When crimping and conveying wire harnesses, wire harnesses of different diameters require different conveying forces. Thin wires need to control the conveying pressure to avoid deformation, while thick wires are heavier and require greater friction to drive them forward.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Embodiment 1, this embodiment proposes a fully automatic multifunctional double-end terminal machine, such as Figure 1 As shown, it includes a workbench 1, a wire harness feeding bin 2 is fixedly installed at the head end of the workbench 1, and a control device 3 is fixedly installed at the tail end and at the side of the workbench 1.

[0038] like Figure 1 As shown, a guide feeding device 4 is provided on the top of the workbench 1. Figure 2 and Figure 3As shown, the guide feeding device 4 includes a fixed shaft 41, a merging plate 42, a torque spring 43, a slider 44 and a guide plate group. The bottom end of the fixed shaft 41 is fixedly installed on the top of the workbench 1. The fixed shaft 41 is rotatably connected to the merging plate 42 at the rod body. The end of the merging plate 42 is elastically connected to the fixed shaft 41. The slider 44 is fixedly installed on the top of the torque spring 43 and close to the end position. Two fixed shafts 41 are set and symmetrically distributed on the top of the workbench 1. The torque springs 43 connected to the two fixed shafts 41 form a V-shaped structure. By moving the end of the wire harness to the torque spring 43, the wire harness passes through the center of the V-shaped structure formed by the two torque springs 43, so that the two torque springs 43 are separated.

[0039] like Figure 3 As shown, a guide plate group for conveying the wire harness is arranged on the side of the slider 44, and a rotating wheel 48 is rotatably connected to the bottom end of the slider 44. Initially, the outer arc surfaces of the rotating wheels 48 connected to the two fixed shafts 41 are in contact. The rotating wheels 48 are used to reduce the friction force on the wire harness, and due to the existence of the merging plate 42, the pressure from the rotating wheels 48 on both sides of the wire harness is the same, so that the wire harness is centered so that the wire harness enters the guide plate group.

[0040] The slider 44 adopts a convex structure, and the side of the slider 44 is slidably connected to a support block 45. The support block 45 is provided with a strip slideway on one side facing the slider 44, and the slider 44 slides in the strip slideway.

[0041] Further, the guide plate group includes two conveying wheel support plates 46 and four guide rods 47. The conveying wheel support plates 46 slide on the top of the workbench 1. The guide rods 47 are fixedly installed on the opposite sides of the two conveying wheel support plates 46. Two symmetrically arranged guide rods 47 are installed on the side of one conveying wheel support plate 46. The fixed part of the guide rod 47 is installed on the top of the workbench 1. The end of the conveying wheel support plate 46 is fixedly connected to the support block 45. A cutting device 7 is arranged on the top of the workbench 1 and at the end of the conveying wheel support plate 46.

[0042] After the torque spring 43 is opened, the torque spring 43 drives the support block 45 to move by means of the slider 44. Due to the existence of the guide rod 47, the conveying wheel support plate 46 can only move in a straight line. The two torque springs 43 are used to avoid the wire harness, so that the torque spring 43 is opened. The torque spring 43 separates the two conveying wheel support plates 46 by means of the slider 44 and the support block 45. The slider 44 and the support block 45 cooperate to prevent the torque spring 43 from being stuck when moving, so as to adjust the opening size of the two conveying wheel support plates 46 by means of the wire harness diameter, so as to guide the wire harnesses with different diameters.

[0043] like Figure 4 and Figure 5As shown, the bottom of the conveying wheel support plate 46 is provided with a friction component 5, including a main conveying wheel 51 and a branch arc block 53. The top of the main conveying wheel 51 is rotatably connected to the guide plate group. The arc surface of the main conveying wheel 51 is slidably connected to a plurality of annular branch arc blocks 53 distributed at equal angles. The main conveying wheel 51 and the branch arc block 53 form a feeding wheel. The outer arc surfaces of the main conveying wheel 51 and the branch arc block 53 are in contact with the wire harness. The wire harness is conveyed by the main conveying wheel 51 and the branch arc block 53, and the distance between the two conveying wheel support plates 46 is adjusted to change the pressure applied by the main conveying wheel 51 and the branch arc block 53 to the wire harness.

[0044] In this embodiment, two torque springs 43 are used to avoid the wire harness so that the torque spring 43 is opened. The torque spring 43 uses a slider 44 and a support block 45 to separate the two conveying wheel support plates 46. The slider 44 and the support block 45 cooperate to prevent the torque spring 43 from moving and getting stuck, so that the opening size of the two conveying wheel support plates 46 is adjusted according to the diameter of the wire harness, and the pressure applied to the wire harness by the main delivery wheel 51 and the branch arc block 53 is changed to apply different conveying forces to wire harnesses of different diameters.

[0045] Embodiment 2, based on embodiment 1, this embodiment proposes a fully automatic multifunctional double-head terminal machine, such as Figure 4 and Figure 5 As shown, the main delivery wheel 51 is provided with a plurality of annular chute grooves 52 distributed at equal angles, and a plurality of branch arc blocks 53 are provided, the number of which is the same as the number of chute grooves 52, and the branch arc blocks 53 slide at the chute grooves 52. When conveying a thin wire bundle, the outer arc surfaces of the main delivery wheel 51 and the branch arc blocks 53 are aligned, and the main delivery wheel 51 and the branch arc blocks 53 jointly transmit the wire bundle; when conveying a thick wire bundle, the branch arc blocks 53 are received in the main delivery wheel 51, and the main delivery wheel 51 generates edges and corners by using the chute grooves 52 thereon. When conveying a thick wire bundle, the edges and corners on the main delivery wheel 51 increase the friction between it and the wire bundle.

[0046] A guide rod 54 is fixedly installed at the inner center of the main feeding wheel 51, and the middle part of the guide rod 54 is slidably connected to the upper ring 55 up and down. The upper ring 55 is hinged to the branch arc block 53 through a hinge rod 56. A magnetic strip 59 is fixedly installed on the top of the workbench 1 and located on the moving path of the conveying wheel support plate 46. A magnetic attraction component is fixedly installed on the bottom of the upper ring 55, and the magnetic attraction component is perpendicular to the magnetic strip 59.

[0047] The magnetic attraction component includes a lower ring 57, a magnetic ring 58 and a reset spring 510. The bottom of the upper ring 55 is rotatably connected to the lower ring 57, and the bottom of the lower ring 57 is fixedly installed with the magnetic ring 58. The magnetic ring 58 adopts a magnetic metal cylinder structure. The reset spring 510 is elastically connected between the top of the upper ring 55 and the main sending wheel 51. The reset spring 510 is used to reset the upper ring 55.

[0048] When the two conveying wheel support plates 46 are opened and moved to the set position, the magnetic ring 58 is now directly above the magnetic strip 59, and the magnetic strip 59 attracts the magnetic ring 58, so that the magnetic ring 58 moves downward, and the magnetic ring 58 drives the lower ring 57 and the upper ring 55 to move downward, and the upper ring 55 uses the hinge rod 56 to pull the branch arc block 53 into the interior of the main conveying wheel 51.

[0049] In this embodiment, when the wiring harness is a thick wiring harness, the distance between the two conveying wheel support plates 46 is large. At this time, when the magnetic ring 58 moves to the top of the magnetic strip 59, the magnetic strip 59 attracts the magnetic ring 58, so that the branch arc block 53 is received in the inside of the main feeding wheel 51, and the main feeding wheel 51 forms the corners of the slide groove 52 to convey the wiring harness, thereby increasing the friction force. When the wiring harness is a thin wiring harness, the magnetic ring 58 is misaligned with the magnetic strip 59, and the outer arc surfaces of the main feeding wheel 51 and the branch arc block 53 are flush, thereby reducing the friction force.

[0050] Embodiment 3, based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a fully automatic multifunctional double-head terminal machine, such as Figure 6 and Figure 7 As shown, a crimping assembly 6 is provided on the top of the workbench 1 and located on the extension line of the end of the conveying wheel support plate 46. The crimping assembly 6 includes a transmission member, an adjustment gear 65, a hydraulic telescopic rod 66, a crimping rod 67 and a gantry 68. The gantry 68 is fixedly installed on the top of the workbench 1. The hydraulic telescopic rod 66 is fixedly installed at the top center of the gantry 68. The telescopic part of the hydraulic telescopic rod 66 is threadedly connected to the crimping rod 67. The adjusting gear 65 is fixedly installed on the outer arc surface of the crimping rod 67. A transmission connection meshing with the adjusting gear 65 is provided on the top of the workbench 1. The crimping rod 67 is used for crimping wire harnesses and terminals.

[0051] like Figure 8 As shown, the crimping rod 67 is rotated by turning the adjusting gear 65, thereby moving the crimping rod 67 upward. Under the condition that the extended length of the hydraulic telescopic rod 66 remains unchanged, the minimum height to which the crimping rod 67 moves is increased. According to the diameter of the wire harness, the height to which the crimping rod 67 can be lowered is adjusted, thereby adjusting the pressure of the crimping rod 67 on the crimping terminal and the wire harness.

[0052] The transmission parts include a transmission shaft 61, a chain 62, a support shaft 63 and a transmission gear 64. The bottom end of the transmission shaft 61 is rotatably connected to the workbench 1, the end of the transmission shaft 61 is meshed with the guide rod 47 through a gear, the top of the transmission shaft 61 is connected to the support shaft 63 through the chain 62, and gears are set at the connection between the transmission shaft 61, the support shaft 63 and the chain 62. The support shaft 63 passes through the gantry 68 and extends to the top of the transmission gear 64.

[0053] The movement is generated by opening the conveying wheel support plate 46, which drives the guide rod 47 to contract, and the guide rod 47 drives the gear to rotate the transmission shaft 61. The transmission shaft 61, the chain 62 and the support shaft 63 cooperate so that the transmission gear 64 rotates, and the transmission gear 64 drives the adjustment gear 65 to rotate to adjust the movable range of the crimping rod 67.

[0054] The transmission gear 64 is meshed and connected with the adjustment gear 65, and the spacing between the upper and lower surfaces of the transmission gear 64 is longer than the spacing between the upper and lower surfaces of the adjustment gear 65. Even if the adjustment gear 65 moves up and down, the transmission gear 64 is always meshed and connected with the adjustment gear 65.

[0055] In this embodiment, the conveying wheel support plate 46 is opened so that the transmission gear 64 rotates, and the transmission gear 64 is used to change the angle of the adjustment gear 65, so that the crimping rod 67 rotates along the thread to change its movable range, and different crimping heights and forces are applied to wire harnesses of different diameters.

[0056] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
