Description

Technical Field

[0001] The present invention relates to wire harness processing equipment, and in particular to a multi-wire multi-terminal intelligent crimping system. Background Art

[0002] The crimping operation of wire harnesses and terminals has currently achieved a relatively high degree of automation through terminal crimping machines. The main raw materials include wire harnesses and terminals. After pre-processing operations such as stripping and inserting bolts (i.e., inserting waterproof bolts), the wire harnesses are introduced into the terminal crimping machine for crimping with the terminals.

[0003] Among them, there are usually two operation methods for the transfer of wire harness raw materials. One is that workers manually introduce the wire harnesses into the terminal crimping machine, and the other is to introduce the wire harnesses into the terminal crimping machine through an automatic clamping and feeding device. Currently, the operation of using an automatic clamping and feeding device to clamp wire harnesses is usually single-line, that is, only a single wire harness is grabbed, and it is impossible to switch to different types of wire harnesses for operation. Although the method of manually introducing wire harnesses can switch wire harness types, the process is cumbersome. Because there are many types of wire harnesses, it is also very easy to take the wrong wire harnesses, resulting in a decrease in the qualification rate.

[0004] At the same time, the transfer device for terminal raw materials is also single-line and can only transfer a specific type of terminal raw material. If different specifications of terminal raw materials need to be replaced, the entire roll of terminal raw materials needs to be replaced manually, and devices such as terminal cutting dies and terminal crimping dies also need to be replaced, which affects the working efficiency when switching different specifications of terminal raw materials.

[0005] Therefore, the terminal crimping machines in the prior art cannot flexibly and quickly switch the raw materials of wire harnesses and terminals, resulting in low manufacturing efficiency during process changes. Summary of the Invention

[0006] In view of the above problems, the present invention proposes a multi-wire multi-terminal intelligent crimping system.

[0007] The present invention is implemented by adopting the following technical solutions:

These attached drawings are part of the disclosure of the present invention, mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operation principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] Now, the present invention will be further described in combination with the attached drawings and specific implementation manners.

[0028] Refer to Figure 1-4 As shown, as a preferred embodiment of the present invention, a multi - wire and multi - terminal intelligent crimping system is provided for realizing the automatic crimping operation of wiring terminals and the ends of wire harnesses. The terminal crimping system includes: wire feeding device 1, wire - selecting device 2, one - side swing arm device 101, two - side swing arm device 102, wire harness pre - processing unit 103, terminal press 3, cutting device 104, terminal conveying device 4 and wire take - up device 5, where:

[0029] (1) Wire feeding device 1

[0030] The wire feeding device 1 is used to convey multiple wire harnesses to the wire - selecting device 2. In this embodiment, a plurality of wire threading guiding mechanisms (not shown in the figure, such as wire threading holes) are provided on the wire feeding device 1 in the vertical direction. A total of 12 wire harnesses of different specifications pass through the wire threading guiding mechanisms in sequence and are conveyed to the wire - selecting device 2. The wire feeding device 1 can be provided with a conveying mechanism to actively convey the wire harnesses to the wire - selecting device 2, or the wire feeding device 1 can also passively introduce the wire harnesses into the wire - selecting device 2 after the wire harness raw materials are extracted by the one - side swing arm device 101 or the two - side swing arm device 102 at the wire - selecting device 2.

[0031] (2) Wire - selecting device 2

[0032] The wire selection device 2 is used for arranging multiple wire harnesses in a split type, and the wire selection device 2 is configured to selectively provide any wire harness thereon to the one-side swing arm device 101 and the two-side swing arm device 102. As Figures 5-7 , the wire selection device 2 includes a moving seat 21 and a wire threading tube 23. The moving seat 21 is driven by a driving device to move up and down in the vertical direction. A plurality of pipe clamps 24 are arranged along the vertical direction on the moving seat 21. A plurality of wire threading tubes 23 are loaded on different pipe clamps 24. Different wire harnesses 300 pass through different wire threading tubes 23. By moving the moving seat 21, different wire threading tubes 23 are switched to a position facing the one-side swing arm device 101 or the two-side swing arm device 102, so that the one-side swing arm device 101 or the two-side swing arm device 102 can pick up and place the wire threading tubes 23 and the wire harnesses 300.

[0033] The wire threading tube 23, as a carrier of the wire harness 300, can be loaded on the pipe clamp 23 or grabbed. Using the wire threading tube 23 is beneficial to the neat arrangement of multiple different wire harnesses 300 and also beneficial to the switching of different wire harnesses 300. In this embodiment, the movement of the moving seat 21 is used to switch different wire harnesses 300 to a position facing the one-side swing arm device 101 or the two-side swing arm device 102. Therefore, multiple different types of wire harnesses can be arranged. For example, a total of 12 different wire harnesses are provided in this embodiment. When one of the wire harnesses needs to be processed, it can be quickly switched to this wire harness.

[0034] (III) One-side swing arm device 101 and two-side swing arm device 102

[0035] With the direction in which the wire feeding device 1 conveys the wire harness to the wire selecting device 2 as forward, the first side swing arm device 101 and the second side swing arm device 102 are respectively arranged on the left side and the rear side of the wire selecting device 2. The movement ranges of the first side swing arm device 101 and the second side swing arm device 102 are generally on the left and right sides of the wire selecting device 2. Claws for grasping the wire harness are provided on both the first side swing arm device 101 and the second side swing arm device 102. Both the first side swing arm device 101 and the second side swing arm device 102 are driven to swing by a swing driving device and can also be driven to slide and stretch by a sliding driving device. Therefore, the first side swing arm device 101 and the second side swing arm device 102 can freely move within the areas of the wire selecting device 2, the wire harness pre-processing unit 103, the terminal press 3, and the wire take-up device 5 to transfer the end of the wire harness. In other embodiments, the first side swing arm device 101 and the second side swing arm device 102 can be configured with more moving mechanisms. For example, the first side swing arm device 101 and the second side swing arm device 102 are configured as six-axis manipulators. It can be understood that if the first side swing arm device 101 and the second side swing arm device 102 can move away from or close to the wire selecting device 2 and can move in the up and down directions, the wire selecting device 2 can be set to be stationary, and the wire selecting device 2 waits for the first side swing arm device 101 and the second side swing arm device 102 to switch the height position to grasp the wire harness thereon. In other embodiments, the second side swing arm device 102 can also be arranged on the right side of the wire selecting device 2.

[0036] The first side swing arm device 101 grabs the selected wire harness and the wire threading tube 23 from the wire selecting device 2, drives the head of the wire harness through the first side swing arm device 101 to be processed in the wire harness pre-processing unit 103 on the left side and the terminal press 3, and then the first side swing arm device 101 puts the wire harness and the wire threading tube 23 back to the wire selecting device 2. Then, the wire feeding device 1 sends the wire harness forward out of the wire threading tube 23. A cutting device 104 is provided on the front side of the wire selecting device 2 for cutting the wire harness after the wire harness is drawn out from the wire selecting device 2, so that the continuous wire harness is cut into separate segments, and each segment of the wire harness has a head and a tail. The second side swing arm device 102 then grabs the tail of the wire harness and processes it in the wire harness pre-processing unit 103 on the right side and the terminal press 3. After the processing is completed, the second side swing arm device 102 transfers the wire harness to the wire take-up device 5. It can be understood that if the movement range of the first side swing arm device 101 or the second side swing arm device 102 is large enough, the work of drawing out the wire harness / taking up the wire by the wire take-up device 5 can also be completed by the first side swing arm device 101 or the second side swing arm device 102.

[0037] (IV) Cutting Device 104

[0038] The cutting device 104 is arranged on the front side of the wire selection device 2 and is used to cut the wire harness after the wire harness is drawn out from the wire selection device 2. The cutting device 104 can adopt any automated cutting device, such as a lifting cutting mechanism driven by a cylinder. The cutting device 104 can be configured to be able to move closer to or away from the wire harness, as long as a moving drive mechanism is added to the cutting device 104.

[0039] (V) Wire harness preprocessing unit 103

[0040] The wire harness preprocessing unit 103 is used to strip and insert bolts (i.e., insert waterproof bolts) into the wire harness. The wire harness preprocessing unit 103 can be implemented by using a stripping device and an inserting bolt device in the prior art. The number of the stripping device and the inserting bolt device can be determined according to actual needs. For example, each inserting bolt in this embodiment is equipped with two stations and can insert a total of four types of waterproof bolts. The stripping device is provided with a vision system in this embodiment, which can detect processes such as inserting bolts and crimping of the wire harness.

[0041] (VI) Terminal conveying device 4

[0042] The terminal conveying device 4 is used to provide terminal raw materials to the terminal press 3. Refer to Figure 8 , the terminal conveying device 4 includes a supply unit 41. There are 12 supply units 41 in total in this embodiment, and the 12 supply units 41 are arranged along the first direction T. Each supply unit 41 is used to supply different specifications of terminal monomers. Among them, the supply unit 41 further includes a storage part 412 and a material distribution part 411. As Figure 9 , the terminal raw material 400 is a structure in which several terminal monomers 401 are connected end to end to form a continuous strip. The terminal raw material 400 is stored in the storage part 412 in a wound manner. The terminal raw material 400 is also guided to the material distribution part 411, and the material distribution part 411 separates the terminal monomers 401 from the terminal raw material 400 one by one.

[0043] There are two pinch conveying units 42 in total. The two pinch conveying units 42 are respectively arranged on the upper and lower sides of the material distribution part 411. The pinch conveying unit 42 further includes a sliding track 421 and a clamping jaw 422. The sliding track 421 is arranged along the first direction T, and the clamping jaw 422 slides on the sliding track 421, so that the pinch conveying unit 42 has a conveying stroke of reciprocating movement along the first direction T. Both of the two clamping jaws 422 can clamp the terminal monomers 401 separated by the material distribution part 411 and carry away the terminal monomers 401, for example, carry the terminal monomers 401 to the terminal press. The range of the conveying stroke of the pinch conveying unit 42 covers the arrangement length of the supply unit 41, so that the pinch conveying unit can convey the terminal monomers 401 separated by the material distribution part 411 of any supply unit 41.

[0044] This embodiment is provided with 12 terminal supply lines. Therefore, in the automated crimping operation of the terminals, different specifications of terminals can be quickly switched for operation. When it is necessary to enable a certain terminal supply line (i.e., enable a certain supply unit 41), the clamping unit 42 can be moved to the position of the corresponding material distribution part 411 to grab the corresponding terminal monomer 401. In addition, in this embodiment, there are two conveying lines of the clamping unit 42, and these two conveying lines of the clamping unit 42 are independent of each other. Therefore, the terminal monomer 401 can be alternately clamped and transported, improving the efficiency of transporting the terminal monomer 401.

[0045] The arrangement direction of the multiple supply units 41 can be flexibly set according to the placement direction of the machine table. In this embodiment, the first direction T is the horizontal direction, and the sliding tracks 421 of the two clamping units 42 are respectively arranged on the upper side and the lower side of the material distribution part 411. Such a design can avoid the machine table occupying too much height space and also make the horizontal movement range of the clamping unit 42 wider.

[0046] The material distribution part 411 can be realized by structures such as cutting and stamping. For example, the material distribution part 411 of this embodiment includes a punch. With reference to Figure 9 , the terminal monomer 401 includes a sheet-shaped connecting part 402, and adjacent terminal monomers 401 are connected through the connecting part 402. By punching the connecting part 402 with the punch, the terminal monomers 401 are separated.

[0047] (Seven) Terminal press 3

[0048] The terminal press 3 is used to realize the crimping operation of the terminals and the wire harness. As Figure 10, the terminal press 3 includes a frame 33, a first cutter head assembly 31 and a second tool changing disc 320 mounted on the frame 33. The first cutter head assembly 31 includes a first tool changing disc 310. The first tool changing disc 310 and the second tool changing disc 320 are arranged opposite to each other and are respectively driven to rotate by different driving devices (such as motors). A plurality of first cutter heads 311 are distributed along the circumferential direction of the first tool changing disc 310, and a plurality of second cutter heads 321 are distributed along the circumferential direction of the second tool changing disc 320. Different first cutter heads 311 and second cutter heads 321 are switched by the rotation of the first tool changing disc 310 and the second tool changing disc 320 to cooperate in pressing the terminals. The specifications of each first cutter head 311 are different, and the specifications of each second cutter head 321 are different. Since the first tool changing disc 310 and the second tool changing disc 320 rotate independently, any first cutter head 311 can be matched with any second cutter head 321, so that different first cutter heads 311 and second cutter heads 321 can be flexibly selected according to the types of the wiring terminals and the wire harnesses. The first cutter heads 311 and the second cutter heads 321 are used as the pressing mechanisms for the terminals and the wire harnesses. When pressing the terminals, the terminals and the wire harnesses are introduced between the first cutter heads 311 and the second cutter heads 321, and the first cutter heads 311 and the second cutter heads 321 approach each other relatively to press the terminals onto the wire harnesses.

[0049] When pressing, the first cutter heads 311 and the second cutter heads 321 need to approach each other relatively. In other words, that is, the first tool changing disc 310 and the second tool changing disc 320 need to approach each other relatively. In this embodiment, the second tool changing disc 320 is set to have a fixed axis, and the first tool changing disc 310 is set to have a movable axis. On this basis, a first adjustment mechanism and a second adjustment mechanism for adjusting the height of the first tool changing disc 310 of the first cutter head assembly 31 can also be provided to respectively coarsely and finely adjust the first tool changing disc 310 to approach or move away from the second tool changing disc 320. Both the first adjustment mechanism and the second adjustment mechanism can adopt a driving device that drives the first tool changing disc 310 to move in the up and down directions. To achieve the fine adjustment function of the second adjustment mechanism, the movement range / amplitude of the second adjustment mechanism should be smaller than that of the first adjustment mechanism, and the movement should also be slower. For example, the second adjustment mechanism can adopt methods such as inclined plane cooperation and deceleration devices to achieve. By setting the first adjustment mechanism and the second adjustment mechanism, the terminal press of this embodiment can flexibly and accurately adjust the pressing height of the first cutter heads 311 according to different types of the first cutter heads 311 and the second cutter heads 321. Due to the cooperation of the coarse adjustment and fine adjustment mechanisms, while ensuring the adjustment speed of the pressing height of the first cutter heads 311, the accuracy can also be ensured to better cooperate with the multi-cutter head design in this embodiment.

[0050] It can be understood that the second tool changing disc 320 can also be provided with a first adjustment mechanism and a second adjustment mechanism with the same principle to enhance the flexibility of adjusting the working distance between the first cutter heads 311 and the second cutter heads 321.

[0051] (8) Take-up device 5

[0052] The take-up device 5 transfers and collects the processed wire harnesses. The take-up device 5 may be provided with a conveying mechanism, a wire merging mechanism, a receiving trough, etc. For example, a conveyor belt is used as the conveying mechanism of the take-up device 5. The processed wire harnesses are transferred to the conveyor belt by the two-side swing arm device 102 and then sent out. The take-up device 5 of this embodiment adopts the prior art, and for details, reference can be made to Patent CN119133982A.

[0053] In this embodiment, the wire selection device 2 is arranged at the central position. The one-side swing arm device 101 and the two-side swing arm device 102 are respectively arranged on the left side and the rear side of the wire selection device 2. The take-up device 5 and the wire feeding device 1 are respectively arranged on the front and rear sides of the wire selection device 2, thus forming a compact and reasonable layout. A set of wire harness processing devices are respectively arranged on the left and right sides of the wire selection device 2. The wire harness processing devices include a wire harness pre-processing unit 103 and a terminal press machine 3. The wire harness processing devices on the left and right sides respectively process the head and tail of the wire harness, so as to complete the processing operations at both ends of the wire harness at one time. The peeling device and the bolt threading device of the wire harness pre-processing unit 103 are arranged along the swinging direction of the one-side swing arm device 101 or the two-side swing arm device 102, so that the peeling and bolt threading of the wire harness can be realized more efficiently.

[0054] In this embodiment, both the one-side swing arm device 101 and the two-side swing arm device 102 can cooperate with the wire selection device 2 to switchably grab different wire harnesses on the wire selection device 2. The terminal conveying device 4 is provided with a plurality of supply units, and different supply units can be used to switchably supply different specifications of terminals to the terminal press machine. Corresponding to different specifications of terminals and wire harnesses, different pressing mechanisms that can be switched for operation are provided on the terminal press machine 3. For different processing situations, the multi-wire and multi-terminal intelligent pressing system of this embodiment can automatically and quickly switch the raw materials of different specifications of wire harnesses and terminals. The multi-wire and multi-terminal intelligent pressing system of this embodiment can provide 12 kinds of wire harnesses, 12 kinds of terminals, and thread 4 kinds of waterproof bolts, thus greatly improving the production efficiency during the process conversion.

[0055] During operation, the wire feeding device 1 feeds wires to the wire selection device 2. The head of the selected wire harness is grabbed from the wire selection device 2 by the one-side swing arm device 101, and the wire harness is transferred to the wire harness preprocessing unit 103 on the left side for peeling and bolt threading. Then, the wire harness is transferred to the terminal press 3 on the left side for crimping. After that, the one-side swing arm device 101 places the wire harness with the head processed back onto the wire selection device 2. The wire feeding device 1 continues to feed wires to the wire selection device 2 so that the head of the wire harness is sent out of the wire selection device 2. The cutting device 104 cuts the wire harness. The two-side swing arm device 102 then grabs the tail of the wire harness and transfers the tail of the wire harness to the wire harness processing device on the right side of the wire selection device 2 for the same processing. Finally, the wire harness with both the head and the tail processed is removed from the wire take-up device 5.
