As shown in fig. 1, in the present embodiment, the automatic wire withdrawing device provided by the present invention is used for withdrawing the pin 220 in the connector 200, and the automatic wire withdrawing device includes a bracket 110, a fixing seat 120 and a needle withdrawing box 130. Referring to fig. 2-5 in combination, fig. 2 representatively illustrates a cross-sectional view taken along line a-a of fig. 1; an enlarged schematic view of the needle withdrawing magazine 130 in a state is representatively shown in fig. 3; an enlarged schematic view of the needle withdrawing magazine 130 in another state is representatively illustrated in fig. 4; fig. 5 representatively illustrates an enlarged schematic view of the needle ejecting magazine 130 mated with the connector 200 in a state;
an enlarged schematic view of the needle ejecting magazine 130 mated with the connector 200 in another state is representatively illustrated in fig. 6. The structure, connection mode and functional relationship of the main components of the automatic wire withdrawing device provided by the invention will be described in detail below with reference to the attached drawings.
As shown in fig. 1 to 4, in the present embodiment, the fixing base 120 is disposed at the bottom of the bracket 110, the fixing base 120 can fix the connector 200 to be disconnected, and the fixing base 120 can be, but is not limited to, in a bench clamp type working mode. The needle withdrawing box 130 is arranged at the top of the bracket 110 in a lifting manner through the driving mechanism 140, the needle withdrawing box 130 is positioned above the fixed seat 120, and the height of the bracket 110 can be calculated and determined according to the driving stroke of the driving mechanism 140 and the matching distance between the connector 200 and the insertion hole 211 (the step surface 2111). The needle withdrawing box 130 includes an upper support plate 131, a lower support plate 132 and an elastic member 135. The upper plate 131 is connected to the driving mechanism 140, and the upper plate 131 is provided with a plurality of pins 133 extending downward. The lower support plate 132 is located below the upper support plate 131, and the lower support plate 132 is provided with a plurality of downwardly extending sleeves 134, the top of the sleeves 134 being open at the top surface of the lower support plate 132. The plurality of thimbles 133 correspond to the plurality of sleeves 134 respectively, and the thimbles 133 are partially inserted into the corresponding sleeves 134. The inner diameter of the lumen of the sleeve 134 is larger than the aperture of the insertion hole 211 of the connector 200 through which the insertion pin 220 is fixedly inserted. The elastic element 135 is connected between the upper support plate 131 and the lower support plate 132, and can play a role in adjusting and buffering the pressure of the thimble 133, and realize automatic withdrawal of the thimble 133 after withdrawing the thimble.
Accordingly, when the connector 200 is withdrawn by using the automatic wire withdrawing device of the present invention, as shown in fig. 5, the needle withdrawing box 130 is substantially in the state shown in fig. 3, the needle withdrawing box 130 is respectively inserted into the accommodating cavities 210 of the connector 200 for accommodating the insertion needles 220 by the plurality of sleeves 134, and the insertion needles 220 of the connector 200 are partially inserted into the lumens of the sleeves 134. Since the inner diameter of the lumen of the sleeve 134 is larger than the aperture of the insertion hole 211 of the connector 200, the sleeve 134 cannot be inserted into the insertion hole 211 and abuts against the bottom step surface 2111 of the accommodating chamber 210. At this time, the driving mechanism 140 continues to drive the needle withdrawing box 130 to descend, that is, specifically, push the upper support plate 131 downward, so that the upper support plate 131 compresses the elastic member 135 to move downward close to the lower support plate 132, during which the relative position of the lower support plate 132 and the connector 200 is not changed. The ejector pins 133 move downward along with the upper support plate 131 until the lower ends of the ejector pins 133 contact the upper ends of the pins 220, and eject the pins 220 out of the connector 200 through the insertion holes 211, thereby completing the operation of ejecting the pins 220 from the connector 200. After the thread is withdrawn, the driving mechanism 140 retracts, the elastic member 135 releases the elastic potential energy to reset the upper support plate 131 relative to the lower support plate 132, and the driving mechanism 140 continues to retract to enable the needle withdrawing box 130 to be integrally withdrawn until the sleeve 134 is upwardly removed from the accommodating cavity 210.
Through the above design, the present invention can simultaneously implement the automatic withdrawing operation of the plurality of pins 220 of the connector 200. Therefore, the connector 200 is short in time and small in occupied manpower when the connector is completely withdrawn in the process of repairing the screen cabinet, artificial uncertain factors in the wire withdrawing operation are greatly reduced through the driving design of the driving mechanism 140 and are not easy to damage, so that the portable and automatic wire withdrawing is realized, the repairing efficiency of the locomotive screen cabinet is improved, the time and the labor are saved, the wire withdrawing is realized in batches, tools are protected, and the cost is saved.
Optionally, in this embodiment, the outer diameter of the thimble 133 may be equal to the inner diameter of the sleeve 134, so that the up-and-down movement of the thimble 133 in the sleeve 134 can be guided by the sleeve 134, and the thimble 133 is prevented from shaking in the sleeve 134. In some embodiments, the outer diameter of thimble 133 may also be slightly smaller than the inner diameter therethrough, but is not limited thereto.
Optionally, as shown in fig. 3 to 6, in this embodiment, the needle withdrawing box 130 may further include a supporting column 136. Specifically, one end of the supporting column 136 is connected to the upper support plate 131, and the lower support plate 132 is slidably sleeved on the other end of the supporting column 136. On this basis, the elastic member 135 may be a spring wound around the supporting column 136, and the spring is located between the upper support plate 131 and the lower support plate 132. Through the design, the invention can further enhance the connection strength between the upper support plate 131 and the lower support plate 132 by utilizing the design of the supporting column 136, thereby optimizing the overall structural strength of the needle withdrawing box 130. Further, the present invention can provide a guiding function and a disposition position of the elastic member 135 using the supporting column 136.

Accordingly, the upper end of the support column 136 may be fixed with the upper support plate 131 by a fastening nut 137. Through the design, the support column 136 and the upper support plate 131 are connected in a threaded connection mode, so that the assembly and disassembly are convenient, and the operation is simple. Furthermore, the present invention can adjust the relative fixing position of the supporting column 136 and the upper supporting plate 131 by adjusting the fastening nut 137, so as to provide different extending strokes of the thimble 133, thereby meeting the wire withdrawing requirements of different types of connectors 200.
Further, as shown in fig. 3 to 6, based on the design that the needle withdrawing box 130 includes the supporting column 136, in the present embodiment, the lower end of the supporting column 136 may be provided with a thread. Accordingly, the lower end of the support column 136 may be threaded with a limit nut 138, the limit nut 138 being located below the lower support plate 132. Through the design, the lower support plate 132 can be limited by the limiting nut 138. Furthermore, the invention can adjust the relative position of the lower support plate 132 and the upper support plate 131 by adjusting the limit nut 138, so as to meet the wire withdrawing requirements of different types of connectors 200.
Alternatively, as shown in fig. 5 and 6, in the present embodiment, thimble 133 may include a first connecting portion 1331 and a needle portion 1332. Specifically, the top of the first connection portion 1331 is provided with a screw hole, so that the first connection portion 1331 can be inserted into the through hole of the upper plate 131 and fixed to the upper bracket 110 by a fastening screw 1333 threadedly engaged with the screw hole. The needle section 1332 is connected to the lower end of the first connecting section 1331 and extends downward, and the needle section 1332 can be inserted into the cannula 134. On this basis, the outer diameter of the needle head section 1332 may be smaller than the outer diameter of the first connecting section 1331, so that the first connecting section 1331 with the larger outer diameter facilitates the arrangement of the screw hole, thereby improving the connection strength of the thimble 133 and the upper support plate 131.
Alternatively, as shown in fig. 5 and 6, in the present embodiment, the sleeve 134 may include a second connection portion 1341 and a tube body 1342, and the lumen of the sleeve 134 penetrates through the second connection portion 1341 and the tube body 1342. Specifically, the outer circumference of the second connection part 1341 is provided with external threads, so that the sleeve 134 can be screw-fixed to a screw hole provided in the lower bracket 110 through the second connection part 1341. A tube body portion 1342 is connected to a lower end of the second connecting portion 1341 and extends downward, and the tube body portion 1342 can be inserted into the receiving cavity 210 of the connector 200. On this basis, the outer diameter of the pipe body 1342 may be smaller than the outer diameter of the second connecting portion 1341, so that the second connecting portion 1341 with a larger outer diameter facilitates the arrangement of the external threads, thereby improving the connection strength between the sleeve 134 and the lower support plate 132.
In addition, based on the specific design of the needle withdrawing box 130, the present invention can selectively connect the thimble 133 with the required number and arrangement form in the plurality of through holes of the upper support plate 131 and select the corresponding screw hole in the plurality of screw holes of the lower support plate 132 to connect the sleeve 134 with the corresponding number and arrangement form for different types of connectors 200. Accordingly, the present invention can realize the adaptation to different types of connectors 200 by the detachable design of the thimble 133 and the sleeve 134, and further expand the application range of the present invention.
