Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, specifically an automated crimping device for wire harness terminals. Background Technology

[0002] Wire harnesses are an indispensable component of electrical equipment. They consist of multiple wires crimped together with connecting terminals. The quality of the terminal crimping directly affects the conductivity, mechanical strength, and reliability of the wire harness.

[0003] However, most of the wire harness terminal crimping equipment currently available on the market can only crimp one terminal to one end of a wire harness at a time, resulting in low work efficiency.

[0004] Chinese patent discloses a high-precision terminal crimping device for wire harnesses (authorization announcement number CN220209592U). This patented technology uses multiple lower pressing molds set in the middle of the upper surface of the second mounting plate and multiple upper pressing molds set in the middle of the lower surface of the first mounting plate to work together, which facilitates the crimping of multiple wire harness bodies and terminal bodies in a single operation. It also facilitates the replacement of different types of molds to complete different crimping operations of wire harness bodies and terminal bodies.

[0005] However, it has certain drawbacks: the terminal body undergoes plastic deformation under the strong pressure of the mold and will be tightly embedded in the second pressing groove on the upper surface of the pressing mold. As a result, after the crimping operation is completed, the terminal is very easy to get stuck in the second pressing groove and is difficult to remove. When the staff removes the material, they often need to use tools or apply a lot of force to pry it out or pull it out, which increases the labor intensity of the operators. Summary of the Invention

[0006] The purpose of this invention is to provide an automated crimping device for wire harness terminals to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automated crimping device for wire harness terminals includes a base, a bottom plate fixed to the upper surface of the base, and a plurality of grooves evenly formed on the upper surface of the bottom plate from left to right.

[0009] A U-shaped seat is fixed to the upper surface of the base outside the base plate. A telescopic cylinder is fixed to the upper surface of the U-shaped seat. A lifting plate is fixed to the telescopic end of the telescopic cylinder. Lifting rods are fixed to the upper surface of the lifting plate on both the left and right sides of the telescopic cylinder. Multiple pressing parts are evenly arranged on the lower surface of the lifting plate from left to right.

[0010] The upper surface of the base is provided with a lifting mechanism outside the base plate. The lifting mechanism includes two lifting plates, left and right. The front and rear ends of the two lifting plates are movably connected with support rods. The front and rear sides of the upper surface of the two lifting plates are fixed with lifting rods. The upper surface of the two lifting plates is provided with a snap-fit ​​component between the two lifting rods.

[0011] Both ends of the lifting plate are provided with snap-fit ​​components, and push plates are fixed to the inner left and right surfaces of the U-shaped seat.

[0012] As a further embodiment of the present invention: the first snap-fit ​​component includes a mounting plate, a plurality of mounting rods are movably connected through the inner side of the mounting plate, a first snap-fit ​​block is fixedly connected to one end of the plurality of mounting rods near the bottom plate, a spring is fixedly connected between the first snap-fit ​​block and the mounting plate, a second snap-fit ​​block is fixedly connected to one end of the plurality of mounting rods away from the bottom plate, and a second snap-fit ​​block is fixedly connected to the upper end of the mounting block.

[0013] As a further embodiment of the present invention: the two lifting plates are respectively located on the left and right sides of the base plate, the lower end of the support rod is fixed to the upper surface of the base, and the two lifting rods are respectively located on the front and rear sides of the base plate.

[0014] As a further embodiment of the present invention: the lower end of the mounting plate is fixed to the upper surface of the lifting plate, and the mounting plate is located between the two lifting rods.

[0015] As a further embodiment of the present invention: the second snap-fit ​​component includes two fixing plates, one at the front and one at the back. A fixing rod is fixedly connected to the inner side of the two fixing plates at the end away from the lifting plate. Fixing sleeves are fixedly sleeved on both the front and back sides of the fixing rod. A U-shaped rod is fixedly connected to the lower end of the two fixing sleeves.

[0016] As a further embodiment of the present invention: the ends of the two fixing plates away from the fixing rod are both fixed to one end of the lifting plate.

[0017] As a further embodiment of the present invention: the crimping member includes a support sleeve, one side surface of the support sleeve is threaded with a support bolt, and the inner side of the support sleeve is movably connected with a crimping connector.

[0018] As a further embodiment of the present invention: the upper end of the support sleeve is fixed to the lower surface of the lifting plate, and one end of the support bolt is attached to the crimp connector.

[0019] As a further embodiment of the present invention: the lifting plate is located inside the U-shaped seat, and the lifting rod moves through the upper surface of the U-shaped seat.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention utilizes a lifting mechanism linked to the crimping action. During the upward stroke after the crimping head is completed by the telescopic cylinder, a U-shaped hook that moves synchronously with the lifting plate catches the locking block one, which is locked due to the crimping descent. This automatically lifts the lifting rod, stably pushing out the wire harness terminal that was stuck in the groove due to the crimping deformation, thus achieving integrated operation of crimping and unloading. This process requires no additional power source or complex control, effectively solving the problem of low efficiency caused by manual removal in traditional operations. At the same time, through the cooperation of the push plate and the locking block two, the linkage can be automatically released and the lifting mechanism can be reset after unloading. In addition, the adjustable design of the crimping head within the support sleeve facilitates quick replacement and maintenance, allowing the device to flexibly adapt to the crimping requirements of different terminal models, enhancing its practicality and economy.

The stripped end of the wire harness is located in the crimping section and is waiting to be crimped. The insertion section of the terminal is located on the rear side of the base plate 2 and is in an unsupported state, leaving space for subsequent crimping deformation and avoiding interference with the base plate 2.

[0032] exist Figures 1-3 In the middle: A U-shaped seat 4 is fixedly connected to the upper surface of the base 1 on the outer side of the base plate 2;

[0033] The opening of the U-shaped base 4 faces downwards, and the two arms are distributed on the left and right sides, that is, the two arms are located on the left and right sides of the base 2 respectively.

[0034] A telescopic cylinder 5 is fixed to the upper surface of the U-shaped seat 4;

[0035] The telescopic cylinder 5 is preferably a pneumatic cylinder;

[0036] A lifting plate 6 is fixedly connected to the telescopic end of the telescopic cylinder 5. The lifting plate 6 is located inside the U-shaped seat 4. Lifting rods 7 are fixedly connected to the upper surface of the lifting plate 6 on both the left and right sides of the telescopic cylinder 5. The lifting rods 7 can move through the upper surface of the U-shaped seat 4.

[0037] The lifting rod 7 is used to improve the stability of the lifting plate 6 when it is raised or lowered;

[0038] Multiple pressing parts 8 are evenly arranged on the lower surface of the lifting plate 6 from left to right;

[0039] The number of crimping parts 8 and grooves 3 are the same, and they correspond one-to-one;

[0040] The crimping component 8 includes a support sleeve 9, the upper end of which is fixed to the lower surface of the lifting plate 6. A support bolt 10 is threaded through one side surface of the support sleeve 9, and a crimping connector 11 is movably connected to the inner side of the support sleeve 9.

[0041] The crimp connector 11 is used for crimping wire harness terminals;

[0042] The lower surface of the support sleeve 9 has a T-shaped sliding hole extending to the front and rear sides, and the upper end of the crimp connector 11 is T-shaped; the crimp connector 11 can be disassembled by loosening the support bolt 10.

[0043] exist Figure 1 , Figure 2 , Figures 4-6In the middle: The upper surface of the base 1 is provided with a lifting mechanism 12 outside the base plate 2. The lifting mechanism 12 includes two lifting plates 13 on the left and right sides respectively. The two lifting plates 13 are located on the left and right sides of the base plate 2. The front and rear ends of the two lifting plates 13 are movably connected with support rods 14. The lower end of the support rods 14 is fixed to the upper surface of the base 1.

[0044] The support rod 14 is used to ensure that the lifting plate 13 can be raised and lowered stably;

[0045] Lifting rods 15 are fixedly connected to both the front and rear sides of the upper surface of the two lifting plates 13, and the two lifting rods 15 are located on the front and rear sides of the base plate 2 respectively.

[0046] The front lifting rod 15 is attached to the front surface of the base plate 2, and the rear lifting rod 15 is attached to the rear surface of the base plate 2.

[0047] The upper surfaces of the two lifting plates 13 are provided with a snap-fit ​​component 16 between the two lifting rods 15. The snap-fit ​​component 16 includes a mounting plate 17. The lower end of the mounting plate 17 is fixed to the upper surface of the lifting plate 13, and the mounting plate 17 is located between the two lifting rods 15. Multiple mounting rods 18 are movably connected through the inner side of the mounting plate 17. The ends of the multiple mounting rods 18 near the bottom plate 2 are jointly fixed with a snap-fit ​​block 19.

[0048] The connection surface between the locking block 19 and the mounting rod 18 is a vertical surface, and the lower surface of the locking block 19 is a horizontal surface. A convex arc surface is formed between the vertical surface and the horizontal surface, that is, the side surface of the locking block 19 facing the base plate 2 is an arc surface.

[0049] A spring 20 is fixedly connected between the locking block 19 and the mounting plate 17;

[0050] The spring 20 is fixed to the locking block 19 and the mounting plate 17 by small screws, so that the spring 20 can be removed and replaced.

[0051] Multiple mounting rods 18 are fixedly connected to a mounting block 21 at their ends away from the base plate 2, and a second locking block 22 is fixedly connected to the upper end of the mounting block 21.

[0052] The connection surface between the second locking block 22 and the mounting block 21 is a horizontal surface, and the surface of the second locking block 22 away from the base plate 2 is a vertical surface. A convex arc surface is formed between the horizontal surface and the vertical surface, that is, the surface of the second locking block 22 facing the base plate 2 is an arc surface.

[0053] Both ends of the lifting plate 6 are provided with snap-fit ​​parts 23. The snap-fit ​​parts 23 include two fixing plates 24 at the front and rear. The inner side of the two fixing plates 24 away from the lifting plate 6 is fixedly connected to a fixing rod 25. Small screws are threaded through and connected to the fixing plates 24 and press against the fixing rod 25.

[0054] The ends of the two fixing plates 24 away from the fixing rod 25 are fixed to one end of the lifting plate 6. The front and rear sides of the fixing rod 25 are fixedly sleeved with fixing sleeves 26. Small screws are threaded through and connected to the fixing sleeves 26 and press against the fixing rod 25.

[0055] Two fixing sleeves 26 are located between two fixing plates 24;

[0056] The lower ends of the two fixing sleeves 26 are jointly fixed with a U-shaped rod 27;

[0057] The opening of the U-shaped rod 27 faces upward, and the two arms are distributed front and back, that is, the ends of the two arms are respectively fixed to the lower ends of the front and rear fixed sleeves 26.

[0058] During the crimping process, when the telescopic cylinder 5 lowers the lifting plate 6 to a certain height, the flat section of the U-shaped rod 27 contacts the locking block 19 and continues to descend, compressing the spring 20. When the crimping piece 8 completely crimps the wire harness terminal, the flat section of the U-shaped rod 27 just descends to the lower side of the locking block 19. After the crimping is completed, the telescopic cylinder 5 retracts, and the U-shaped rod 27 drives the locking block 19 to move upward, thereby driving the entire locking piece 16 to move upward, which in turn drives the two lifting rods 15 to rise. The front lifting rod 15 lifts the wire harness upward, and the rear lifting rod 15 lifts the insertion section of the terminal upward, pushing the wire harness terminal that was deformed by the crimping and stuck in the groove 3 upward.

[0059] exist Figure 1 , Figure 5 and Figure 6 In the middle: Push plates 28 are fixedly connected to the inner left and right surfaces of the U-shaped seat 4;

[0060] The push plate 28 consists of a horizontal section and a vertical section fixed to the downward side of the horizontal section; the end of the horizontal section away from the vertical section is fixed to the U-shaped seat 4, and the lower end of the vertical section is pointed;

[0061] When the U-shaped rod 27 moves the first locking piece 16 upward to a certain height, the push plate 28 contacts the arc-shaped surface of the second locking block 22, causing the second locking block 22 to produce a horizontal displacement and compress the spring 20. The first locking block 19 simultaneously produces a horizontal displacement, thus leaving the flat section of the U-shaped rod 27. The first locking piece 16 will then drive the lifting rod 15 to descend and reset.

[0062] The working principle of this invention is as follows: The operator first inserts the stripped wire harness end into the crimping section of the terminal, then places the assembly into the corresponding groove 3 on the base plate 2, ensuring the crimping section of the wire harness and terminal is stably positioned in the groove 3, while the terminal insertion section extends backward into a suspended state. After all the wire harness terminals to be crimped are positioned in this manner, the telescopic cylinder 5 is activated. Its telescopic end drives the lifting plate 6 and multiple crimping connectors 11 installed on its lower surface to descend synchronously. Each crimping connector 11 is precisely pressed into the corresponding groove 3, completing the plastic crimping of the wire harness and terminal crimping section. During the process, the U-shaped rod 27, which descends with the lifting plate 6, first presses down and locks onto the lower side of the locking block 19; after the pressing is completed, the telescopic cylinder 5 rises, and the U-shaped rod 27 drives the entire lifting mechanism 12 to rise by hooking the locking block 19. The lifting rod 15 then lifts the pressed wire harness terminal from the groove 3 to unload it; when the lifting plate 6 continues to rise to a certain height, the push plate 28 squeezes the locking block 22, forcing the locking block 19 to move horizontally and disengage from the U-shaped rod 27. The lifting mechanism 12 then descends and resets under the action of gravity, thus completing a complete automatic pressing and unloading cycle.
