[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] In order to solve the technical problems of low efficiency and easy crooked insertion when manually aligning the needle sleeves of the pins and plugging them in, the utility model provides a manual wire crimping device that can achieve convenient plugging and quick connection of wire crimping.

[0036] It should be noted that the manual wire crimping device described in the present invention is used for but not limited to crimping pins and wires. For the sake of convenience, in the present invention, only the manual wire crimping device is used for crimping pins and wires as an example. The principle of using the manual wire crimping device in other types of equipment is essentially the same as the principle of using it for crimping wire harnesses and end terminals, so they will not be described in detail here.

[0037] See also Figure 1-7The present invention provides a manual wire crimping device for crimping a pin with a needle sleeve with a wire, and the needle sleeve is connected to the wire sleeve, wherein one end of the wire exposes the wire core, and the manual wire crimping device comprises a feeding mechanism 1, a clamping assembly 2, a guide assembly 4 and a pressing assembly 3. The feeding mechanism 1 has a discharge end 101 for pointing the needle sleeve of the pin toward the discharge direction and loading the material from the discharge end 101, so as to face the insertion port of the needle sleeve outward for feeding and connecting the subsequent steps with the wire core 7; the clamping assembly 2 is arranged on the discharge end 101 of the feeding mechanism 1, and is used to clamp the needle sleeve 6 of the discharged pin, and push the needle sleeve of the pin to the discharge end 101 in the feeding mechanism 1, and feed it into the clamping assembly 2 from the discharge end 101, and then be clamped and positioned for wire crimping; the guide assembly 4 is coaxially arranged on the other side of the pressing assembly 3, and has a semi-openable and closable The conical mouth 41, the end of the semi-conical mouth 41 is provided with a semi-circular notch 4101 matching the outer diameter of the wire, which is used to guide the wire to be inserted into the closed semi-circular notch 4101. When the semi-conical mouth 41 is closed, it forms a conical trough body, and the conical surface inside it guides the center of insertion when inserting the wire 7, so that it can slide into the circular hole formed by the closure of the two semi-circular notches 4101 located in the center, thereby accurately inserting it into the needle sleeve of the pin, improving the accuracy of the plugging in the manual plugging operation, and avoiding the error of crooked insertion; the pressing component 3 is coaxially arranged on the other side of the clamping component 2, located between the wire component 4 and the clamping component 2, for pressing the needle sleeve of the pin and the wire core of the wire 7, the needle sleeve is exposed in the pressing component 3, the wire core is inserted into the needle sleeve, and the pressing component 3 is started to perform wire crimping to complete the connection between the needle sleeve and the wire.

[0038] In this embodiment, the feeding mechanism 1 feeds the needle sleeves of the plug pins one by one toward the discharge end 101, pushes them into the clamping assembly 2 to be clamped and positioned, and exposes the end portion in the pressing assembly 3. At this time, the wire 7 is manually held, and the stripped and exposed wire core end is inserted into the guide assembly 4. During the insertion step, the two semi-conical nozzles 41 of the guide assembly 4 are in a closed state to guide the insertion of the wire 7. After insertion, it is pressed through the pressing assembly 3, and then the two semi-conical nozzles 41 are separated, the clamping assembly 2 is loosened, and the wire crimped with the pin sleeve can be pulled out.

[0039] Furthermore, it also includes a workbench body 5, and the feeding mechanism 1, the clamping assembly 2 and the pressing assembly 3 are all installed on the top of the workbench body 5 through a base frame.

[0040] In one embodiment, see Figure 3 and Figure 4In order to form a crimping connection between the needle sleeve of the pin and the wire core of the wire, the pressing assembly 3 includes a driving member 31 and a pressing head 32. Several of the pressing heads 32 are arranged in a circle with the discharge end 101 of the feeding mechanism 1 as the axis. There are four pressing heads 32. The output end of the driving member 31 is connected to the pressing head 32, which is used to drive the multiple pressing heads 32 to gather or disperse toward the axis of the circumferential distribution, thereby forming a four-sided pressing effect.

[0041] In this embodiment, in order to simultaneously drive multiple pressure heads 32 to gather and disperse, the driving member 31 includes a linear driving mechanism 311, an outer ring 312 and an elastic member 313. A connecting rod 314 is hinged on the movable end of the linear driving mechanism 311. The connecting rod 314 is connected to the outer ring 312. When the linear driving mechanism 311 moves up and down, it can drive the connecting rod 314 to drive the outer ring 312 to rotate around the base 23. The inner side of the outer ring 312 is provided with an outer expansion groove 315 corresponding to the pressure head 32. One side of the elastic member 313 is provided with an outer expansion groove 315. The ends of the pressing heads 32 are connected one-to-one with the pressing heads 32, and the other ends are connected with the base 23. When not pressed initially, the tail end of the pressing head 32 abuts against the inner wall of the outward expansion groove 315. Under the rotation of the outer ring 312, the inner wall of the outer ring 312 abuts against the tail end of the pressing head 32, thereby pushing the pressing head 32 toward the center of the circle to form a gathering. When the outer ring 312 rotates in the opposite direction until the tail end of the pressing head 32 returns to the outward expansion groove 315, the elastic member 313 elastically pushes back to disperse the pressing heads 32, thereby achieving the purpose of driving multiple pressing heads 32 to gather or disperse toward the axis of the circumferential distribution.

[0042] It can be understood that the linear drive mechanism 311 can adopt a linear guide pair or a screw guide pair.

[0043] Furthermore, in order to provide position limiting guidance during the sliding movement of the pressing head 32 , a plurality of first through slots 2301 are provided on the base 23 , and the pressing head 32 is slidably connected to the first through slots 2301 in a one-to-one correspondence.

[0044] In one embodiment, see Figure 2 and Figure 3In order to clamp the needle sleeve part of the pin, the clamping assembly 2 includes a telescopic mechanism 21, a chuck 22 and a base 23. The base 23 is arranged adjacent to the discharge end 101 of the feeding mechanism 1. The telescopic mechanism 21 is installed on the base 23 through a bracket. The chuck 22 is arranged at the telescopic end of the telescopic mechanism 21, and is used to drive the chuck 22 to retract and retract, and clamp or loosen the needle sleeve of the pin on the base 23. The top of the base 23 is provided with a recess, which is opposite to the discharge end 101. The needle sleeve part of the pin is pushed into the recess and is blocked by the closed semi-conical mouth 41 to form a limit. At this time, the telescopic mechanism 21 pushes the chuck 22 to move downward, thereby cooperating with the base 23 to clamp the needle sleeve part of the pin.

[0045] It is understandable that the inner diameter of the semicircular notch 4101 is smaller than the outer diameter of the needle sleeve, so when the semi-conical mouth 41 is closed, it can form a stop for the needle sleeve and limit its position. The telescopic mechanism 21 can use a hydraulic push rod or a pneumatic push rod.

[0046] In one embodiment, see Figure 4 and Figure 6 In order to close during guidance, the guide assembly 4 includes an elastic telescopic member 42 and a pushing mechanism 43. The elastic telescopic member 42 is installed on the base 23, and the semi-conical nozzle 41 is installed at the telescopic end of the elastic telescopic member 42. The pushing mechanism 43 is installed on the base 23, and its movable end abuts against the semi-conical nozzle 41, which is used to push the two semi-conical nozzles 41 together or away from each other.

[0047] Specifically, the pushing mechanism 43 includes a pneumatic push rod 431 and a pulling head 432. The pulling head 432 is arranged at the telescopic end of the pneumatic push rod 431. The end of the pulling head 432 has two pull rods 433. The two pull rods 433 are provided with an inverted slope 434 on the opposite side. The top of the semi-conical mouth 41 is provided with a through opening 4102. The pull rod 433 is slidably connected in the corresponding through opening 4102, and is used to push the two semi-conical mouths 41 away from each other with the inverted slope 434 when moving downward.

[0048] Furthermore, in order to improve the stability of the telescopic movement, a second through slot 2302 corresponding to the elastic telescopic member 42 is opened on the base 23, and the elastic telescopic member 42 is slidably connected in the first through slot 2301.

[0049] It can be understood that the elastic telescopic part 42 has a fixed end and a telescopic end, and the fixed end and the telescopic end are connected by a spring to form elastic expansion and contraction, and has an elastic thrust to push the two semi-conical mouths 41 to close, and when the pull rod 433 moves downward, the two semi-conical mouths 41 are separated. Conversely, when the pull rod 433 moves upward, the elastic telescopic part 42 elastically pushes the two semi-conical mouths 41 to close.

[0050] In one embodiment, see Figure 1 and Figure 2 The feeding mechanism 1 includes a circular vibration plate 11, a vibrator and a feeding pipe 12. The circular vibration plate 11 is fixed on the vibrator. A spiral track is provided on the circular vibration plate 11. One end of the feeding pipe 12 is connected to the spiral track. The discharge end is arranged at the other end of the feeding pipe 12. The vibrator can drive the circular vibration plate 11 to vibrate in the vertical direction and torsional vibration around its vertical axis, so that the stranded wire pins in the circular vibration plate 11 rise along the spiral track and are fed into the feeding pipe 12. The stranded wire pins entering from the front and back are arranged at one time and abutted head to tail to form a pushing effect.

[0051] It is understandable that the vibrator can be a composite vibrator, which is usually equipped with two or more excitation units, each unit is responsible for generating a vibration mode. This type of vibrator is designed to generate two vibration modes at the same time to meet the needs of specific applications. It is an existing mature equipment; for the positive and negative orientation of the stranded wire pins, machine vision can be used to make a judgment, and a pneumatic mechanism can be used to spray air to blow the stranded wire pins with incorrect directions off the spiral track. I will not go into details here.

[0052] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the present invention is described in detail: the feeding mechanism 1 feeds the needle sleeves of the plug pins one by one toward the discharge end 101, pushes them into the clamping assembly 2 to be clamped and positioned, and exposes the end portion in the pressing assembly 3. At this time, the wire 7 is manually held, and the stripped and exposed wire core end is inserted into the guide assembly 4. During the insertion step, the two semi-conical nozzles 41 of the guide assembly 4 are in a closed state to guide the insertion of the wire 7. After insertion, the pressing assembly 3 drives the structural pressure head 32 to close for pressing. Then, the two semi-conical nozzles 41 are separated, and the clamping assembly 2 is loosened, and the wire crimped with the pin sleeve can be pulled out.

[0053] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
