Description

Technical Field

[0001] This application relates to the technical field of terminal crimping, and more particularly to a multi-station crimping machine. Background Technology

[0002] Terminal crimping is one of the most important steps in wire harness manufacturing. Crimping a type of terminal generally requires a corresponding set of molds. Traditional terminal crimping machines only have one set of molds and can only crimp one type of terminal. If certain wire harnesses need to crimp multiple types of terminals, multiple terminal crimping machines must be used, which is costly. Alternatively, if a terminal crimping machine is used, after processing one type of terminal, the mold needs to be disassembled and replaced with another mold for crimping, which is cumbersome and not suitable for assembly line production.

[0003] Therefore, it is necessary to provide a low-cost, multi-station crimping machine that does not require disassembly or mold replacement. Utility Model Content

[0032] Please refer to Figures 1-6This utility model provides a multi-station crimping machine, which includes a rotating table 10, a pressing assembly 20, and a crimping assembly 30. The pressing assembly 20 includes a first drive source 21 and a pressing head 22. The crimping assembly 30 includes an upper die 31 and a lower die 32. The upper die 31 presses against the lower die 32 to achieve terminal crimping. There are multiple crimping assemblies 30, which are distributed circumferentially on the rotating table 10. The upper die 31 and lower die 32 of each crimping assembly 30 are of different types. When one of the crimping assemblies 30 rotates to below the pressing head 22, the first drive source 21 can drive the pressing head 22 to press the upper die 31 against the lower die 32 to crimp the corresponding type of terminal.

[0033] In this embodiment, the rotary table 10 is provided with multiple crimping components 30, and the upper mold 31 and lower mold 32 of each crimping component 30 are of different models, so that the multi-station crimping machine can crimp various terminals without disassembling and changing the molds, thus making it more applicable. Each crimping component 30 can be adjusted in position by means of the rotation of the rotary table 10, so that the multi-station crimping machine only needs to be set with one pressing mechanism, which can save costs. Furthermore, the design of setting multiple crimping components 30 on the rotary table 10 for transmission can further reduce the space occupied by the multi-station crimping machine compared with the solution of linear transmission of multiple crimping components 30, so that the processing plant can place more multi-station crimping machines or other equipment in a limited space.

[0034] In a preferred embodiment, reference may be made to Figure 1 Preferably, there are six crimping components 30, which are evenly distributed around the circumference of the rotating table 10 and spaced apart from each other. Of course, in other embodiments, the number of crimping components 30 may be two or more, and no further limitation is made here.

[0035] In a more specific embodiment, see reference to Figure 2 The pressing assembly 30 also includes a first housing 33 and a first sliding member 34. The first sliding member 34 is slidably connected to the first housing 33, the upper mold 31 is fixed to the first sliding member 34, and the pressing head 22 applies pressure to the top of the first sliding member 34, which can drive the first sliding member 34 to slide relative to the first housing 33 and cause the upper mold 31 to press down on the lower mold 32.

[0036] Preferably, the first sliding member 34 includes a main body 341 and an extension 342. The main body 341 is slidably connected to the first housing 33, and the extension 342 is connected to the top of the main body 341. When the pressure head 22 presses down, it abuts against the extension 342 to drive the upper mold 31 to press down. The design of the extension 342 can reduce the distance between it and the pressure head 22, and the smaller volume of the extension 342 can further reduce the weight of the first sliding member 34.

[0037] In a preferred embodiment, when the pressure head 22 rises, it magnetically attracts the top of the extension 342 to drive the upper mold 31 to rise. The extension 342 or its top is a first magnetic attractor to magnetically attract the pressure head 22, and the pressure head 22 or its bottom is a second magnetic attractor.

[0038] In a preferred embodiment, reference may continue to be made to Figure 2 The first sliding member 34 also includes a limiting part 342, which is connected to the side wall of the main body 341. The first housing 33 includes a first sliding groove 331 and a limiting groove 332. The limiting groove 332 is formed in the side wall of the first sliding groove 331. The first sliding groove 331 is used for sliding of the main body 341, and the limiting groove 332 is used for sliding of the limiting part 342. When the main body 341 slides up and down along the first sliding groove 331, it drives the limiting part 342 to slide in the limiting groove 332. The sliding stroke of the limiting part 342 in the limiting groove 332 is limited, thereby limiting the sliding stroke of the main body 341 and the upper mold 31, which can prevent the upper mold 31 from being damaged due to excessive downward pressure.

[0039] In one feasible embodiment, an elastic element (not shown in the figure) is provided in the limiting groove 332. The elastic element is preferably a spring. When the pressure head 22 rises, the elastic element is used to drive the first sliding member 34 and the upper mold 31 to rise.

[0040] In a preferred embodiment, since different wire harnesses have different terminal crimping requirements, especially wire harnesses that require crimping multiple terminals and have multiple corresponding branches, the crimping assembly 30 further includes a wire splitter 35 to facilitate wire splitting and terminal crimping. The top of the wire splitter 35 is provided with multiple wire splitting grooves 351. Specifically, the wire splitter 35 is located at the front end of the lower mold 32, and the wire splitter 35 and the lower mold 32 are spaced apart.

[0041] In a preferred embodiment, reference may be made to Figure 1 , Figure 4 Especially Figure 3 To make the multi-station crimping machine more compact and further reduce the height space it occupies, the pressing assembly 20 also includes a reversing component 24. The reversing component 24 includes a connecting plate 241, a connecting shaft 242, and an eccentric shaft 243. The connecting shaft 242 is fixed to one side of the connecting plate 241, and the eccentric shaft 243 is fixed to the other side of the connecting plate 241. The connecting shaft 242 is fixed to the output shaft of the first drive source 21, and the eccentric shaft 243 is eccentrically positioned to drive the pressing head 22 to press down.

[0042] In this embodiment, the first drive source 21 can be a motor. The first drive source 21 can be placed horizontally, meaning its output shaft is horizontally positioned. When the first drive source 21 is running, it can drive the commutator 24 to rotate. The eccentric shaft 243 is eccentrically positioned with respect to the output shaft of the first drive source 21, thereby outputting a downward force through the eccentric shaft 243 to drive the pressure head 22 downward. Compared to a scheme where the first drive source 21 is a cylinder or electric cylinder and is vertically positioned above the pressure head 22, the structure in this embodiment is more compact, further reducing the height space occupied by the multi-station crimping machine.

[0043] Furthermore, to ensure smooth transmission between the reversing member 24 and the pressure head 22, the pressing assembly 20 also includes a second housing 23, a second sliding member 25, and a slider 26. The second housing 23 has a second sliding groove 231, the second sliding member 25 is slidably connected to the second sliding groove 231, and the second sliding member 25 has a third sliding groove 251. The slider 26 is rotatably connected to the eccentric shaft 243, and the slider 26 is slidably connected to the third sliding groove 251. The pressure head 22 is fixed to the bottom of the second sliding member 25.

[0044] In this embodiment, when the first drive source 21 is running, it drives the reversing member 24 to rotate, thereby causing the eccentric shaft 243 to rotate relative to the slider 26, and driving the slider 26 to slide relative to the third sliding groove, and driving the second sliding member 25 to slide relative to the second sliding groove 231, so as to drive the pressure head 22 to press against the upper die 31. In this process, the stroke of the eccentric shaft 243 is converted into the horizontal sliding of the slider 26 and the vertical sliding of the second sliding member 25. The connection between the reversing member 24 and the pressure head 22 is reliable and the transmission is smooth.

[0045] Of course, in some other embodiments that do not use the commutator 24, the first drive source 21 may also be a vertically arranged electric cylinder or pneumatic cylinder.

[0046] In a preferred embodiment, reference may be made to Figure 1 and Figure 5 To drive the rotation of the rotating table 10, the multi-station crimping machine also includes a gear ring 41, a transmission gear 42, and a second drive source 43. The gear ring 41 is fixed to the bottom of the rotating table 10, and the inner circumference of the gear ring 41 is provided with multiple transmission teeth. The transmission gear 42 meshes with the inner circumference of the gear ring 41. The second drive source 43 is used to drive the transmission gear 42 to rotate, thereby driving the gear ring 41 and the rotating table 10 to rotate.

[0047] Preferably, to reduce the weight of the rotary table 10 and facilitate wiring and material feeding for the multi-station crimping machine, it can be combined with... Figure 6The rotating platform 10 has multiple recesses 11 and vertically connected openings 13. The recesses 11 are distributed around the outer periphery of the rotating platform 10 and extend radially inwards. A placement portion 12 for placing the pressing assembly 30 is formed between two adjacent recesses 11. The openings 13 can be located either inwards from the recesses 11 or in the placement portion 12.

[0048] In one specific embodiment, see reference Figure 3 and Figure 6 The rotating platform 10 is also provided with a connecting cylinder in the middle. The connecting cylinder is used to install the cylindrical bottom of the second housing 23, and the middle part of the connecting cylinder is connected vertically, which also facilitates wiring.

[0049] In one specific embodiment, see reference Figure 4 and Figure 5 The multi-station crimping machine also includes a housing 44 and a surrounding plate 45. The housing 44 is located on the bottom side of the rotating table 10, and the surrounding plate 45 is located on the top of the housing 44, and on the outer periphery of the rotating table 10. Preferably, the surrounding plate 45 is also located on the outer periphery of the gear ring 41, and the cross-section of the surrounding plate 45 is annular.

[0050] Furthermore, the multi-station crimping machine also includes a feeding tray 50. The feeding tray 50 is located inside the housing 44, and the number of feeding trays 50 corresponds to the number of crimping assemblies 30. The feeding trays 50 are used to feed materials to the crimping assemblies 30 above. The terminals supplied by each feeding tray 50 are of different types to match the corresponding type of terminals crimped by each crimping assembly 30.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
