Description

Technical Field

[0001] This utility model belongs to the technical field of terminal crimping mechanisms, specifically relating to a terminal crimping device capable of crimping multiple terminals. Background Technology

[0002] During the production process, the wire harness undergoes a terminal crimping process, as specified in the authorization announcement number CN117855998B. This process crimps the terminals onto the wires so that they can be electrically connected to other components after the wires are processed into a wire harness.

[0003] As electronic products become smaller and more multifunctional, many wire harness products (such as automotive wire harnesses and household wire harnesses) require the integration of terminals of various specifications, such as terminals of different sizes, shapes, or electrical characteristics. Existing terminal crimping machines can usually only be configured with a single terminal hopper, which makes it impossible for the equipment to flexibly switch or process multiple terminals simultaneously. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a crimping device that can crimp multiple terminals.

[0005] To achieve the above objectives, this utility model discloses a terminal crimping device capable of crimping multiple terminals, including a feeding mechanism, a conveying mechanism, and a crimping mechanism; the feeding mechanism is used to input terminal strips and cut them to form terminals; the feeding mechanism is located behind the crimping mechanism; the crimping mechanism includes an installation mechanism, and there are multiple feeding mechanisms and multiple installation mechanisms, all of which are arranged in a left-right direction; The handling mechanism includes a first handling component and a second handling component; The first conveying assembly includes a first slide that can move left and right and a first gripper disposed on the first slide. The first slide is located between the feeding mechanism and the end-cutting mechanism. The first slide can move to any position opposite to the feeding mechanism and clamp the terminal with the first gripper. The second transport component is located beside the feeding mechanism, and the second transport component can transport the terminals on the first gripper to the corresponding mounting mechanism.

[0006] Preferably, the end-cutting mechanism further includes a base that can move left and right, and a plurality of the mounting mechanisms are fixedly connected to the base. The base can be moved to a position where any of the mounting mechanisms is opposite to the second transport component.

[0007] Preferably, the first conveying assembly further includes a turntable, which is fixedly connected to the first slide, and the first gripper is fixedly connected to the turntable.

[0008] Preferably, a transfer clamp is provided between the first transport component and the terminal clamping mechanism, the transfer clamp being used to clamp the terminal on the first gripper.

[0009] Preferably, the turntable can be rotated so that the gripping portion of the first gripper is aligned left and right with the gripping portion of the intermediate frame.

[0010] Preferably, the second handling component includes a mounting frame, a second slide, and a second gripper. The mounting frame is located beside the feeding mechanism, the second slide is slidably connected to the mounting frame, and the second gripper is fixedly connected to the second slide.

[0011] Preferably, the second conveying component further includes a vertical moving component, which is fixedly connected to the second slide, and the second gripper is fixedly connected to the vertical moving component.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The device is equipped with multiple feeding mechanisms and a crimping mechanism, including multiple crimping installation mechanisms. Each feeding mechanism provides a terminal strip and cuts it to form a terminal. Under the action of a first transport component and a second transport component, the terminal is transported to the corresponding installation mechanism for crimping. This device can crimp various types of terminals with high efficiency, meeting the needs of existing wire harnesses for crimping multiple terminals.

[0013] The first slide is located between the feeding mechanism and the end-cutting mechanism, meaning the feeding mechanism, the first slide, and the mounting mechanism are arranged sequentially from back to front. The arrangement directions of the multiple feeding mechanisms, the multiple mounting mechanisms, and the movement direction of the first slide are all along the left-right direction, allowing for a compact front-back arrangement. The second handling component is located beside the feeding mechanism. No large space needs to be left between the feeding mechanism and the mounting mechanism to install the second handling component, ultimately ensuring a compact overall structure and reducing the floor space required.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] A crimping device capable of crimping multiple terminals, see [link to documentation]. Figures 1-8 It includes a feeding mechanism 200, a handling mechanism 300, and a cutting mechanism 400.

[0017] The feeding mechanism 200 is used to input the terminal strip 110 and cut off the terminal 120 at the head through the cutter 210. The terminal strip 110 can be fed using an existing structure such as a ratchet. The cutter 210 is located at the front end of the mechanism. During the cutting process, the terminal 120 is clamped and fixed by the conveying mechanism 300. After cutting, the conveying mechanism 300 transports the terminal 120.

[0018] For ease of subsequent explanation, terminal 120 will be described first. Terminal 120 includes a mating portion 121 and crimping tabs 122 extending outward from both sides of the mating portion 121. Before cutting, all the crimping tabs 122 of the terminals 120 are connected together, forming a terminal strip 110. During cutting, the terminal 120 is cut off at the position of the crimping tab 122.

[0019] During the handling of terminal 120, the handling mechanism 300 clamps and moves the crimping piece 122 of terminal 120.

[0020] The feeding mechanism 200 is located behind the crimping mechanism 400. The crimping mechanism 400 includes a mounting mechanism 410, which performs crimping processing to crimp and fix the terminal 120 to the wire. The mounting mechanism 410 adopts an existing crimping mounting mechanism. There are multiple feeding mechanisms 200 and mounting mechanisms 410, specifically three in total. Each of the three feeding mechanisms 200 provides a terminal strip 110, and the three mounting mechanisms 410 perform crimping processing on the corresponding terminal 120. The three feeding mechanisms 200 and the three mounting mechanisms 410 are all arranged in a left-right direction.

[0021] The conveying mechanism 300 includes a first conveying component 310 and a second conveying component 320. The first conveying component 310 includes a first connecting seat 311 arranged in a left-right direction, a first slide 312 sliding left-right on the connecting seat, and a first gripper 313 disposed on the first slide 312. The first connecting seat 311 is positioned between the feeding mechanism 200 and the terminal crimping mechanism 400. The first slide 312 is slidably connected to the first connecting seat 311 via a guide rail slider structure and is driven by a screw and nut structure. The first gripper 313 uses existing grippers, such as pneumatic grippers. The first slide 312, when driven, can move to a position opposite to either feeding mechanism 200 and grip the crimping tab 122 of the terminal 120 using the first gripper 313. The second conveying component 320 is located beside the feeding mechanism 200 and can transport the terminal 120 on the first gripper 313 to the corresponding mounting mechanism 410.

[0022] By setting up multiple feeding mechanisms 200 and a crimping mechanism 400 including multiple mounting mechanisms 410 for crimping and crimping, each feeding mechanism can provide a terminal strip 110 and cut it to form a terminal 120. Under the action of the first transport component 310 and the second transport component 320, the terminal 120 is transported to the corresponding mounting mechanism 410 for crimping. This device can crimp multiple types of terminals 120 with high efficiency, meeting the needs of existing wire harnesses for crimping multiple types of terminals 120.

[0023] The first slide 312 is located between the feeding mechanism 200 and the end-cutting mechanism 400, meaning the feeding mechanism 200, the first slide 312, and the mounting mechanism 410 are arranged sequentially from back to front. The arrangement directions of the multiple feeding mechanisms 200, the multiple mounting mechanisms 410, and the movement direction of the first slide 312 are all along the left-right direction, allowing for a compact arrangement along the front-back direction. The second handling assembly 320 is located beside the feeding mechanism 200. No large space needs to be left between the feeding mechanism 200 and the mounting mechanism 410 to install the second handling assembly 320, ultimately ensuring a compact layout and reducing the floor space required.

[0024] In this embodiment, for example, when the terminal strip 110 is fed, the mating portions 121 of all its terminals 120 are located on the right side, and the crimping tabs 122 are located on the left side. When the terminals are cut off, the two crimping tabs 122 need to be located on the front side, and the mating portions 121 need to be located on the rear side. The cut-off terminals 120 need to be repositioned. Therefore, the first conveying assembly 310 also includes a turntable 314, which is fixedly connected to the first slide block 312. The first gripper 313 is fixedly connected to the turntable 314 via a connecting rod 315. After clamping the terminals 120 cut off by the feeding mechanism, the turntable 314 rotates so that the first gripper 313 clamps the crimping tabs 122 of the terminals 120, and then rotates 90 degrees. In this embodiment, it is a 90° counterclockwise rotation. At this time, the mating portions 121 of the terminals 120 are located on the rear side, and the two crimping tabs 122 are located on the left and right sides of the front side (the first gripper 313 clamps the right crimping tab 122). Then the first slide 312 moves to the right to the next transport position.

[0025] A transfer clamp 500 is provided on the first connecting seat 311, opposite to the terminal crimping mechanism 400. The transfer clamp 500 is located between the first transport assembly 310 and the terminal crimping mechanism 400. After the turntable 314 rotates 90°, the clamping part of the first gripper 313 (that is, the position that clamps the crimping piece 122) is aligned left and right with the clamping part of the transfer clamp 500. During the movement of the first connecting seat 311, the transfer clamp 500 is in the open state, allowing the clamping part of the first gripper 313 to move through the transfer clamp 500. When the first slide 312 moves to the left side where the crimping piece 122 is opposite to the transfer clamp 500, the first crimping piece 122 stops moving, and the transfer clamp 500 clamps the left crimping piece 122 of the terminal 120. Then the turntable 314 continues to rotate counterclockwise to avoid interference with the transfer clamp 500, and the first slide 312 moves to the left to the initial position.

[0026] The second handling assembly 320 includes a mounting frame 321, a second slide 322, and a second gripper 323. The mounting frame 321 is a gantry frame, arranged front to back, and located beside the rightmost loading mechanism 200. The second slide 322 is slidably connected to the mounting frame 321, and the second gripper 323 is fixedly connected to the second slide 322. After the first slide 312 is removed, the second slide 322 moves forward until the gripping portion of the second gripper 323 is aligned with the right-side pressing plate 122, then clamps, and the transfer clamp 500 releases. The second slide 322 then continues to move forward until the terminal 120 is placed on the mounting mechanism 410.

[0027] The above-mentioned terminal 120 is transported and its posture adjusted by the first gripper 313, the intermediate gripper 500 and the second gripper 323, which are equipped with a turntable 314. The whole process is smooth and efficient.

[0028] In this embodiment, the second conveying assembly 320 further includes a vertical moving assembly 324, which is fixedly connected to the second slide 322, and the second gripper 323 is fixedly connected to the vertical moving assembly 324. The vertical moving assembly 324 allows for adjustment of the gripping height of the second gripper 323, improving its applicability, and also enables it to move upwards to avoid the second slide 322. The vertical moving assembly 324 can also be a lead screw and nut structure for transmission.

[0029] In this embodiment, the end-cutting mechanism 400 also includes a base 420 that can move left and right. Three mounting mechanisms 410 are fixedly connected side by side to the base 420. The base 420 can be moved so that any mounting mechanism 410 is opposite to the second conveying component 320. By moving the base 420, the position of any mounting mechanism 410 can be adjusted so that each mounting mechanism 410 can be opposite to the second gripper 323, thereby enabling the loading of each mounting mechanism 410. The left and right movement of the base 420 is also achieved through a screw and nut structure.

[0030] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
