The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] See also Figures 1 to 4A wire feeding device of the present invention includes: a frame 100, the frame 100 is provided with a translation mechanism 200 that can move back and forth in the left and right directions; a movable plate 300, which is arranged at the output end of the translation mechanism 200, and the movable plate 300 is connected to a first driving mechanism 310 that drives it to move back and forth in the front and back directions; at least two movable seats 400, which are distributed side by side on the movable plate 300 in the left and right directions, and the movable seats 400 are all connected to a second driving mechanism 500, and the second driving mechanism 500 is used to drive the movable seat 400 to move telescopically relative to the movable plate 300 in the front and back directions; the movable seat 400 is provided with a wire passing channel 410 for the wire to pass through and a tightening mechanism 600 for tightening the wire to the inner side wall of the wire passing channel 410.

[0032] When the wire feeding device of the above structure transports the wire, a wire is passed through each wire channel 410, and the wire is tightened and fixed by the tightening mechanism 600. The movable plate 300 is driven to move by the translation mechanism 200 so that each wire is aligned with the processing station in turn. The second driving mechanisms 500 are operated in turn to drive the wires on the corresponding movable seat 400 to extend one after another. When the wire needs to be stripped, the first driving mechanism 310 drives the movable plate 300 to move back and forth to realize the stripping function. The wire feeding device can transport multiple wires at the same time, can assist multiple wires to complete the processing process in turn, improve production and processing efficiency, and can match the subsequent automated wire plugging process to improve the degree of automation of the production line.

[0033] See also Figure 1 and Figure 2 In some embodiments of the present invention, a wire guide tube 420 is removably mounted on the front end of the movable base 400. The internal channel of the wire guide tube 420 interfaces with the wire passage 410, and the diameter of the internal channel of the wire guide tube 420 matches the diameter of the wire. It is understood that wire guide tubes 420 of different specifications can be replaced according to the diameter of the wire to be processed, thereby adapting to different production needs without having to completely replace the wire feeding device, simplifying the assembly and commissioning processes.

[0034] See also Figure 2 and Figure 3 In some embodiments of the present invention, the front end of the movable seat 400 is provided with a plug-in pipe 431, and one end of the wire tube 420 is movably inserted into the plug-in pipe 431. The movable seat 400 is provided with an elastic locking mechanism 700 that can extend into the plug-in pipe 431 to fix the wire tube 420. It is understandable that when the wire tube 420 is inserted into the plug-in pipe 431, the elastic locking mechanism 700 can automatically elastically fix the wire tube 420, which is conducive to improving the replacement efficiency of the wire tube 420, facilitating the operation of production personnel, and improving the convenience of use. It should be noted that in other embodiments, the wire tube 420 can also be disassembled and installed by screw locking and other methods, which will not be further described here.

[0035] See also Figure 2 and Figure 4 In some embodiments of the present invention, in order to further improve the efficiency of disassembly and assembly of the wire tube 420, the outer peripheral wall of the wire tube 420 is provided with a circle of radially inwardly recessed annular grooves 421, and the elastic locking mechanism 700 includes a pressing column 710 movably arranged on the movable seat 400, and the outer peripheral wall of the pressing column 710 is provided with an avoidance groove 711 for the wire tube 420 to pass through, and the pressing column 710 is connected to a first elastic member 720. The first elastic member 720 can drive the avoidance groove 711 to be misaligned with the wire tube 420 so that the pressing column 710 partially extends into the annular groove 421 to prevent the wire tube 420 from detaching from the plug-in pipe 431. It should be noted that when the user applies force to the pressing post 710 to compress the first elastic member 720, the avoidance groove 711 does not contact the outer peripheral wall of the wire tube 420, and the wire tube 420 can be smoothly withdrawn along the plug-in pipe 431. When the user no longer applies force to the pressing post 710, under the action of the first elastic member 720, at least a portion of the pressing post 710 can enter the annular groove 421, thereby preventing the wire tube 420 from being withdrawn along the plug-in pipe 431. In this embodiment, the pressing post 710 is arranged in the vertical direction, and the avoidance groove 711 is shaped like a hyperbolic paraboloid. The curvature radius of the avoidance groove 711 is consistent with the curvature radius of the outer cylindrical surface of the wire tube 420. When the avoidance groove 711 moves to a certain height, the wire tube 420 can be smoothly withdrawn along the plug-in pipe 431.

[0036] See also Figure 2 In some embodiments of the present invention, the front end of the movable seat 400 is provided with an embedding groove 470 arranged along the up-down direction, and a connecting seat 430 is installed in the embedding groove 470. The movable seat 400 is detachably connected to a lower pressure plate 440 that rests against the upper end surface of the connecting seat 430. A second elastic member 450 is provided between the movable seat 400 and the lower end of the connecting seat 430, which can drive the upper end surface of the connecting seat 430 to rest against the lower pressure plate 440. The plug-in pipe 431 is provided on the connecting seat 430, and the connecting seat 430 is provided with a mounting through hole 432 for the pressing column 710 to pass through. The mounting through hole 432 is connected to the side of the plug-in pipe 431 so that a part of the pressing column 710 can extend into the annular groove 421. Among them, the installation through hole 432 is arranged in the up and down direction, and the pressing column 710 can be raised and lowered in the installation through hole 432. When the avoidance groove 711 is aligned with the connection between the installation through hole 432 and the plug-in pipe 431, the wire tube 420 can be pulled out along the plug-in pipe 431.

[0037] It should be noted that the embedding groove 470 is a dovetail groove arranged up and down. Under the action of the second elastic member 450, the connecting seat 430 presses upward against the lower pressure plate 440 to align the plug-in pipe 431 with the wire pipe 420. The lower pressure plate 440 is configured in a detachable connection manner. A gasket can be set between the lower pressure plate 440 and the upper end face of the connecting seat 430 to adjust the height position of the plug-in pipe 431 to connect with the wire pipe 420.

[0038] See also Figure 3 In some embodiments of the present invention, a wire-passing channel 410 is provided through the movable seat 400 in the front-to-back direction. The movable seat 400 is provided with a bifurcated channel 460 connected to the side of the wire-passing channel 410. The tightening mechanism 600 includes a supporting cylinder, and the output end of the supporting cylinder is connected to a supporting member 610 that moves telescopically along the bifurcated channel 460. It should be noted that after the wire passes through the wire-passing channel 410, in order to prevent the wire from moving relative to each other and affecting the normal progress of the wire stripping process or the terminal riveting process, the output end of the supporting cylinder is extended along the bifurcated channel 460 to allow the supporting member 610 to press the side of the wire. The above tightening mechanism 600 has a simple structure and is easy to operate.

[0039] See also Figure 1 In some embodiments of the present invention, the output end of the translation mechanism 200 is fixedly connected to the translation plate 210, and the movable plate 300 is slidably arranged on the translation plate 210 along the front-to-back direction. The first driving mechanism 310 is a first screw mechanism arranged on the translation plate 210, and the output end of the first screw mechanism is connected to the movable plate 300. The movable plate 300 is provided with a plurality of slide rail grooves 320 at intervals along the left-right direction. The slide rail grooves 320 extend along the front-to-back direction, and each slide rail groove 320 is slidably provided with a movable seat 400. It is understandable that when wire stripping is required, the second drive mechanism 500 drives the corresponding movable seat 400 to extend forward along the slide rail groove 320. At this time, the end of the wire extends into the wire stripping device 800. After the two cutters of the wire stripping device 800 clamp the end of the wire, the first screw mechanism drives the movable plate 300 to move backward, thereby stripping the surface of the wire end. Then, the translation mechanism 200 drives the translation plate 210 to move in the left and right directions by the width distance between the two adjacent slide rail grooves 320, so that the wire on the other movable seat 400 is aligned with the wire stripping device 800. Then, the above operation steps are repeated until all wires complete the wire stripping process. It should be noted that the translation mechanism 200 is a second screw mechanism, and the second screw mechanism drives the translation plate 210 to move with higher precision and stability.

[0040] See also Figure 1In some embodiments of the present invention, the movable plate 300 is provided with a mounting bracket 330 located behind the slide rail slot 320. The second drive mechanism 500 is a push cylinder mounted on the mounting bracket 330. The output end of the push cylinder is connected to the movable seat 400 and is arranged parallel to the slide rail slot 320. The mounting bracket 330 is provided with a wire guide channel corresponding one-to-one with the wire guide channel 410. It will be understood that the mounting bracket 330 provides mounting space for multiple push cylinders, and the wire guide channel on the mounting bracket 330 is used to accommodate longer wires to prevent one end of the wires from becoming tangled.

[0041] See also Figure 1 In some embodiments of the present invention, the mounting bracket 330 is provided with a first threading plate 331 extending in the left-right direction. The first threading plate 331 is provided with a plurality of first threading holes 332 spaced apart. The mounting bracket 330 is provided with a plurality of second threading holes 333 corresponding to the first threading holes 332. The first threading holes 332, the second threading holes 333, and the wire passage 410 are aligned. It will be appreciated that the area between the first threading holes 332 and the second threading holes 333 constitutes the wire passage, eliminating the need for drilling to form the wire passage and simplifying its structure.

[0042] See also Figure 5 The present invention also discloses a wire stripping and terminal crimping machine, comprising the wire feeding device described above, wherein a frame 100 is provided with a wire stripping device 800 and a terminal riveting device 900 on the same side of the translation mechanism 200. The wire stripping device 800 and the terminal riveting device 900 are production and processing equipment well known to those skilled in the art and are not described in detail here. The wire stripping and terminal crimping machine with the above structure can simultaneously feed multiple wires, can assist in sequentially completing the wire stripping and terminal riveting processes for multiple wires, improve production and processing efficiency, and can be compatible with the subsequent automated wire insertion process, thereby facilitating an increase in the degree of automation of the production line.

[0043] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
