Detailed implementation manners

[0024] The following will Figures 1 to 8 describe the present utility model in detail with reference to the attached drawings.

[0025] The double-layer multi-axis wire rack of a terminal machine of the utility model includes a fixed rack 1. The fixed rack 1 is successively provided with a bottom plate 11, a layer plate 12, and a top plate 13, so that the fixed rack 1 has a double-layer structure for placing terminal wire coils. The space between the bottom plate 11 and the layer plate 12 is the first layer, and the space between the layer plate 12 and the top plate 13 is the second layer. A number of positioning cylinders 14 are provided on the bottom plate 11 and the layer plate 12. The positioning cylinders 14 in the first layer are staggered with the positioning cylinders 14 in the second layer. A crank arm 2 is provided above the positioning cylinder 14. An inlet wire wheel 21, a first guide wheel 22, and a first directional wheel are successively arranged on the crank arm 2. An inlet wire hole 24 is provided near the inlet wire wheel 21. The layer plate 12 is provided with a first wire passing hole 121, and the top plate 13 is provided with a second wire passing hole 131. A second directional wheel 132 is provided at the top of the top plate 13 at the second wire passing hole 131. A positioning plate a 15 is provided on one side of the top plate 13. A number of third wire passing holes 151 are provided on the positioning plate a 15. A wire releasing rack 3 is provided on one side of the fixed rack 1. The wire releasing rack 3 is provided with a second guide wheel 3123 corresponding to the third positioning hole, and a lifting wheel 32 corresponding to the second guide wheel 3123. A counterweight 33 is provided on the lifting wheel 32. A positioning plate b 34 is provided at the top of the wire releasing rack 3. The positioning plate b 34 is provided with third directional wheels 341 corresponding to the lifting wheel 32 and arranged in an inclined order. A number of fourth wire passing holes 35 corresponding to the height of the third directional wheels 341 are provided on one side of the positioning plate b 34. The terminal wire coil is sleeved on the positioning cylinder 14. The terminal wire material passes through the inlet wire hole 24, is positioned by the inlet wire wheel 21, and the direction is calibrated by the first guide wheel 22, and then is guided to the first wire passing hole 121 or the second wire passing hole 131 through the first directional wheel. The terminal wire material enters the second directional wheel 132 through the second wire passing hole 131, is guided by the second directional wheel 132 to the third wire passing hole 151. After the terminal wire material passes through the corresponding third wire passing hole 151, it successively passes through the second guide wheel 3123, the lifting wheel 32, the third directional wheel 341, and finally passes through the fourth wire passing hole 35 and enters the terminal machine. During the wire releasing process, the terminal machine pulls the terminal wire material to generate a pulling force. The lifting wheel 32 moves upward under the influence of the pulling force. The counterweight 33 provides weight for the lifting wheel 32, so that the lifting wheel 32 pulls the terminal wire material towards the fixed rack 1. This structure enables the terminal machine to indirectly pull the terminal wire material in the fixed rack 1 to form a flexible wire pulling structure, which can prevent the terminal wire material from being broken due to excessive pulling force of the terminal machine. In the scheme of the utility model, the fixed rack has a double-layer structure for placing terminal wire coils, and can release a large amount of wires at the same time. The terminal wire material enters the wire releasing rack 3 through multi-axis guiding. The wire releasing rack 3 then synchronously releases multiple terminal wire materials in sequence through multi-wheel linkage. The number of wires released is large and the efficiency is high.

[0026] A vertical plate 122 is provided at the bottom of the laminated board 12 and the top plate 13. A cross beam plate 123 is provided at the bottom of the vertical plate 122. A rotary disc device 25 is provided on the cross beam plate 123. The rotary disc device 25 can be rotated passively. The crank arm 2 is connected to the bottom of the rotary disc device 25. The rotary disc device 25 is provided with a guide hole 251 that can cooperate with the first wire passing hole 121 and the second wire passing hole 131. During the process of unwinding the terminal wire coil, the terminal wire material is wound around the terminal wire coil. The connection between the crank arm 2 and the rotary disc device 25 enables the crank arm 2 to rotate in cooperation with the terminal wire material. The terminal wire material passes through the rotary disc device 25 through the guide hole 251. The rotation of the rotary disc device 25 will not affect the terminal wire material, and the structural stability is high.

[0027] A resistor 124 that can abut against the top of the rotary disc device 25 is provided on the vertical plate 122. Since the crank arm 2 has a certain volume and weight, during the rapid wire pulling process of the terminal punching device, the rotation speed of the crank arm 2 is fast, and rotational inertia will be generated after rotation. The resistor 124 can brake the rotary disc device 25 to eliminate this rotational inertia. More specifically, the resistor 124 is externally connected with an electric signal wire. When the terminal punching device stops pulling the wire, the resistor 124 is activated to brake and stop the rotary disc device 25, and then release it, so that the lifting wheel 32 can slowly pull the terminal wire material during the reset process.

[0028] A driving wheel 125 is provided on the vertical plate 122. A driven wheel 126 is provided on one side of the driving wheel 125. A motor 127 is provided at the rear end of the driving wheel 125. The driving wheel 125 and the driven wheel 126 cooperate to clamp the terminal wire material. Since the diameter of the terminal wire coil will continuously decrease after unwinding, and the required pulling force will increase after reaching a certain level, the pulling force during the reset process of the lifting wheel 32 to pull the terminal wire material cannot be adjusted adaptively. In this solution, the driving wheel 125 can provide a certain amount of power to assist the lifting wheel 32 in pulling the terminal wire material.

[0029] A number of protective shells 133 are provided between the laminated board 12 and the top plate 13. Both ends of the protective shell 133 are fixed outside the first wire passing hole 121 and the second wire passing hole 131. The protective shell 133 can isolate and limit the position of the terminal wire material, preventing the terminal wire materials on the upper and lower layers from touching and knotting, and the safety performance is high.

[0030] The wire unwinding rack 3 is provided with a number of guide posts 36. Each counterweight 33 is movably connected to two guide posts 36. A buffer spring 37 is provided at the bottom of each guide post 36. The buffer spring 37 can support the counterweight 33 to prevent the counterweight 33 from contacting the bottom of the wire unwinding rack 3.

[0031] On one side of the fixing frame 1, several first sensors 16 are arranged near the position of the positioning plate a15. The first sensors 16 are provided with limit blocks 161 at positions corresponding to the counterweight 33. The first sensors 16 are trigger-type sensors. Generally, when the wire terminal equipment is pulling the wire, the lifting wheel 32 of the solution of the present utility model should be in the middle position of the wire pay-off frame 3 and should have good up and down movement space. After the terminal wire coil is consumed, or when the terminal wire material is stuck somewhere on the fixing frame 1, the terminal wire material is no longer pulled. Under the pulling force of the wire terminal equipment, the lifting wheel 32 will continuously rise until the counterweight 33 touches the limit block 161, the first sensor 16 is triggered, the wire terminal equipment stops pulling the wire, and alarms the staff to remind the staff to check the wire pay-off situation of the terminal wire material.

[0032] On one side of the fixing frame 1, several second sensors 17 are arranged near the bottom position of the wire pay-off frame 3. The second sensors 17 can sense the counterweight 33. The second sensors 17 are infrared sensors. During the reset process of the lifting wheel 32, the motor 127 drives the driving wheel 125 to assist in pulling the wire. When the lifting wheel 32 is reset, the second sensor 17 senses the counterweight 33, and the motor 127 stops operating. The structural linkage is high, and it is convenient and safe to use.

[0033] A rotatable connecting piece 141 is arranged on the positioning cylinder 14, and a wire positioning hole 142 is arranged on the connecting piece 141. After the terminal wire coil is placed on the positioning cylinder 14, one end of the terminal wire material passes through the inlet hole 24, and the other end of the terminal wire material is bound to the wire positioning hole 142. After the terminal wire coil is consumed, the terminal wire material can no longer be pulled. At this time, the connecting piece 141 cooperates with the pulling force generated by the wire terminal equipment to lift the lifting wheel 32 until the first sensor 16 is triggered.

[0034] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
