Description

Technical Field

[0001] This application relates to the field of crimping technology, and more particularly to a crimping device. Background Technology

[0002] In the manufacturing process of modern electronic and electrical equipment, the crimping between comb components and terminals is a critical step in ensuring the proper functioning and reliability of the equipment. Combs are typically used to connect multiple circuits, ensuring the efficient transmission of signals and power.

[0003] As electronic device designs become more diverse and complex, market demands for comb components are constantly evolving. Beyond standard flat comb components, an increasing number of designs are incorporating irregularly shaped comb components, including those with flanges, bends, or other non-planar structures. These irregularly shaped comb components can better adapt to specific design requirements, improving device performance and space utilization.

[0004] However, due to their design limitations, traditional crimping equipment can usually only be used to process standard flat comb parts. When faced with irregularly shaped comb parts, these devices cannot effectively crimp them, resulting in reduced production efficiency, unstable product quality, increased production costs, and also limiting the innovation and diversification of electronic equipment design. Utility Model Content

[0005] This application provides a crimping device to at least partially solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this application provides a crimping device having intersecting first and second directions. The crimping device includes: a cylinder with a piston rod connected to one side in the first direction; a first connector connected to the side of the cylinder with the piston rod; a pull rod including a first rod portion and a second rod portion, the first rod portion extending along the first direction and partially passing through the first connector, the second rod portion extending along the second direction and located on the side of the first connector away from the cylinder, the two ends of the first rod portion in the first direction being connected to the second rod portion and the piston rod respectively; a first crimping assembly located on the side of the pull rod in the third direction and used for crimping a first crimped component; and a second crimping assembly located on the other side of the pull rod in the third direction and used for crimping a second crimped component and a third crimped component.

[0007] The crimping device of this application, by setting a first crimping component and a second crimping component, can crimp a first, a second, and a third component to be crimped, respectively. This design makes the crimping device suitable not only for crimping standard flat comb parts, but also for effectively crimping irregularly shaped comb parts, thereby greatly improving the compatibility of the crimping device. It eliminates the need to purchase multiple dedicated machines for different types of comb parts, reducing equipment procurement and maintenance costs. The crimping device can quickly adapt to different types of comb parts, reducing the time spent changing equipment or adjusting the device, thus significantly improving production efficiency and further reducing production costs.

[0057] In use, the crimping device 100 of this application pre-assembles the first terminal 202 and the first comb piece 201 to form a first crimped assembly 200, pre-assembles the second terminal 302 and the second comb piece 301 to form a second crimped assembly 300, and pre-assembles the third terminal 402 and the third comb piece 401 to form a third crimped assembly 400. The first crimped assembly 200 is placed in the gap between the second limiting part 431 and the first pressing connecting part 412, and in the gap between the second limiting part 431 and the first limiting connecting part 422; or the second crimped assembly 300 is placed in the gap between the support member 54 and the second pressing member 51, and in the gap between the first support part 522 and the first connecting member 2; or the third crimped assembly 400 is placed in the gap between the support member 54 and the second pressing member 51, the gap between the support member 54 and the first support part 522, and the gap between the first support part 522 and the first connecting part 531. Within the gap; when switch 9 is turned on, the piston rod 101 of cylinder 1 retracts, driving the pull rod 3 to move towards cylinder 1 along the first direction M. The pull rod 3 drives the first pressing part 411 to press the first terminal 202 towards the first comb piece 201 for crimping, or the pull rod 3 drives the second pressing part 511 to press the second terminal 302 towards the second comb piece 301 for crimping, or the pull rod 3 drives the second pressing part 511 to press the third terminal 402 towards the third comb piece 401 for crimping; when the detection element 8 detects that the terminals (first terminal 202, second terminal 302 and third terminal 402) and the comb pieces (first comb piece 201, second comb piece 301 and third comb piece 401) are crimped into place, after a delay, the piston rod 101 of cylinder 1 is automatically controlled to extend, and the operator can take out the crimped components (first crimped component 200, second crimped component 300 and third crimped component 400).

[0058] The crimping device 100 of this application, by providing a first crimping component 4 and a second crimping component 5, can respectively crimp a first crimped component 200, a second crimped component 300, and a third crimped component 400. This design allows the crimping device 100 to not only crimp standard flat-type comb parts but also effectively crimp irregularly shaped comb parts, thereby greatly improving the compatibility of the crimping device 100. It eliminates the need to purchase multiple dedicated devices for different types of comb parts, reducing equipment procurement and maintenance costs. The crimping device 100 can quickly adapt to different types of comb parts, reducing the time spent changing equipment or adjusting the device, thus significantly improving production efficiency and further reducing production costs.
