Description

Technical Field

[0001] This invention relates to the field of wire feeding device technology, and more specifically to a wire terminal crimping and feeding device. Background Technology

[0002] In the prior art, equipment for crimping terminals includes a wire feeding device, a terminal crimping mechanism, and a wire cutting device. The terminal crimping mechanism and the wire cutting device are often integrated, with the wire being cut immediately after crimping the terminal. However, the aforementioned devices have the following drawbacks:

[0003] (1) The wire cutting process occupies the terminal crimping station. Therefore, the terminal crimping station can only perform the terminal feeding operation after the wire cutting, which affects the efficiency of terminal crimping.

[0004] (2) During the crimping process, the guided wires are prone to displacement, which reduces the accuracy of the crimping. Summary of the Invention

[0005] Therefore, the present invention provides a wire terminal crimping and feeding device to solve the above-mentioned defects in the prior art.

[0006] A wire terminal crimping and feeding device, comprising:

[0007] A guiding mechanism, installed on the conveyor platform, provides guidance for the wire.

[0008] The wire feeding mechanism includes a turntable disposed at the end of the guide mechanism, a fixed plate disposed on the turntable, and a hinge plate hinged to the fixed plate at its inner end. The fixed plate and the hinge plate are connected by a return spring. The hinge plate is provided with a guide assembly for driving the wire forward. A wire tube is disposed at the front end of the hinge plate, and a U-shaped groove is disposed at the rear end of the hinge plate. A pressing block that can cooperate with the U-shaped groove is disposed on the fixed plate. A wire roller is disposed on the fixed plate at the rear end of the U-shaped groove. The wire passing around the side of the wire roller passes sequentially through the U-shaped groove, the guide assembly, and the wire tube. The turntable drives the fixed plate to rotate back and forth between the tangent position and the crimping position. When the fixed plate rotates to the tangent position, the wire on it is parallel to the wire feeding direction of the guide mechanism. When the fixed plate rotates to the crimping position, the wire on it forms an angle with the wire feeding direction of the guide mechanism. A pressure guide is disposed above the crimping position to press down the far end of the hinge plate.

[0009] Preferably, the guiding mechanism includes a limiting component and a wire assembly arranged sequentially along the conveying direction. The wire assembly is located near the turntable. The wire assembly includes a guide rail arranged perpendicular to the wire conveying direction on the conveying table and a bidirectional lead screw that is rotatably driven to rotate by a knob and arranged parallel to the direction of the guide rail. Two sliding blocks are slidably arranged on the guide rail. The two sliding blocks are set on the screws of the bidirectional lead screw with different directions of rotation through a lead screw nut (not shown in the figure). A plurality of first pressure rollers are arranged equidistantly on the sliding blocks, and the first pressure rollers on the two sliding blocks are staggered.

[0010] Preferably, the limiting assembly includes two vertically arranged limiting rods, and the conveyed wire passes through the gap between the two limiting rods.

[0011] Preferably, the guiding assembly includes two wheel sets arranged parallel to each other on the hinge plate. Each wheel set includes two guide rollers driven to rotate by a motor. The shafts of the two guide rollers in the same set are connected by a synchronous belt. The two guide rollers are connected by a conveyor belt. The inner sides of the two conveyor belts run in the same direction. The guide wire is clamped between the two conveyor belts for transport.

[0012] Preferably, a plurality of second pressure rollers are further provided on the hinge plate between the two guide rollers in the same group, and the inner wall of the second pressure rollers is tangent to the corresponding conveyor belt.

[0013] Preferably, the pressure guide is a convex rail disposed on one side of the pressing device, and a pressure plate is connected above the far end of the hinge plate, and a guide wheel that can interact with the convex rail is disposed on the pressure plate.

[0014] The present invention has the following advantages:

[0015] (1) The present invention can automatically clamp and relax the wire during the rotation of the turntable between the tangent station and the crimping station. When clamping the wire, it can prevent the wire from being displaced during the crimping process and improve the crimping accuracy of the terminal. When the wire is not clamped, the wire parallel to the conveying direction can achieve smooth adjustment of the wire cutting length.

[0016] (2) The wire of the present invention can automatically adjust the angle in the height direction during the rotation process. When the wire rotates to the crimping station, the guide is first positioned above the terminal card interface, and the wire is positioned relative to the terminal during the pressing process. During the lifting process of the wire moving away from the crimping station, the wire connected to the terminal can be pulled away from the terminal carding station. The device of the present invention improves the efficiency of wire terminal crimping and wire feeding as a whole. Attached Figure Description

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 4 As shown, the present invention provides a wire terminal crimping and feeding device, including a guiding mechanism 2 and a feeding mechanism 3.

[0027] The guiding mechanism 2 is mounted on the conveyor table 1 to guide the guide wire 10. Specifically:

[0028] The guiding mechanism 2 includes a limiting component and a guide wire assembly arranged sequentially along the conveying direction. The guide wire assembly is located near the turntable 301. The guide wire assembly includes a guide rail 202 arranged on the conveying table 1 perpendicular to the conveying direction of the guide wire 10 and a bidirectional lead screw 205 rotatably driven to rotate by a knob 206 and arranged parallel to the direction of the guide rail 202. Two sliding blocks 203 are slidably arranged on the guide rail 202. The two sliding blocks 203 are set on the screws of the bidirectional lead screw 205 with different directions of rotation through a lead screw nut (not shown in the figure). A plurality of first pressure rollers 204 are arranged equidistantly on the sliding blocks 203, and the first pressure rollers 204 on the two sliding blocks 203 are staggered.

[0029] The limiting assembly includes two vertically arranged limiting rods 201, and the conveying wire 10 passes through the gap between the two limiting rods 201.

[0030] The wire feeding mechanism 3 includes a turntable 301 disposed at the conveying end of the guide mechanism 2, a fixed plate 302 disposed on the turntable 301, and a hinge plate 303 hinged to the fixed plate 302 at its inner end. The fixed plate 302 and the hinge plate 303 are connected by a return spring 313. The hinge plate 303 is provided with a guide component for driving the wire 10 forward. The front end of the hinge plate 303 is provided with a wire tube 309, and the rear end of the hinge plate 303 is provided with a U-shaped groove block 215. The fixed plate 302 is provided with a component that can cooperate with the U-shaped groove block 215. The pressing top block 214, the fixed plate 302 is located at the rear end of the U-shaped groove block 215 and is provided with a guide roller 216. The guide 10 passing around the guide roller 216 passes sequentially through the U-shaped groove block 215, the guide assembly and the guide tube 309. The turntable 301 drives the fixed plate 302 to rotate back and forth between the tangent station 20 and the crimping station 30. When the fixed plate 302 rotates to the tangent station 20, the guide 10 on it is parallel to the guide mechanism 2 guide 10 conveying direction; when the fixed plate 302 rotates to the crimping station 30, the guide 10 on it forms an angle with the guide mechanism 2 guide 10 conveying direction.

[0031] Above the crimping station 30, a pressure guide is provided to press down the distal end of the hinge plate 303. The pressure guide is a convex rail 311 provided on one side of the crimping device. A pressure plate 312 is connected above the distal end of the hinge plate 303. The pressure plate 312 is provided with a guide wheel 310 that can interact with the convex rail 311.

[0032] The guiding assembly includes two wheel sets arranged parallel to each other on the hinge plate 303. Each wheel set includes two guide rollers 305 driven to rotate by a motor 307. The shafts of the two guide rollers 305 in the same group are connected by a synchronous belt 308, and the two guide rollers 305 are connected by a conveyor belt 306. The inner sides of the two conveyor belts 306 run in the same direction, and the guide wire 10 is clamped between the two conveyor belts 306 for transport. Several second pressure rollers 304 are also provided on the hinge plate 303 between the two guide rollers 305 in the same group. The inner wall of the second pressure rollers 304 is tangent to the corresponding conveyor belt 306, which enhances the friction between the conveyor belt 306 and the guide wire 10.

[0033] The working principle of the device of the present invention includes the following steps:

[0034] 1. Terminal crimping:

[0035] The guide roller 305 is driven to rotate by the motor 307, so that the guide roller 305 connected to the synchronous belt 308 rotates synchronously. The wire 10 clamped inside the conveyor belt 306 is clamped, conveyed and passes through the wire tube 309.

[0036] Then, the drive turntable 301 is rotated, and the stretched wire 10 on the turntable 301 rotates from the tangent station 20 to the crimping station 30. During the rotation, the guide wheel 310 at the upper end of the hinge plate 303 contacts the convex rail 311 that protrudes downward on the side of the terminal crimping device. The guide wheel 310 is squeezed by the convex rail 311, thereby pressing down the pressure plate 312 connected to the guide wheel 310 and the hinge plate 303 connected to it. When the hinge plate 303 is pressed down to a horizontal state, the wire 10 at the front end of the wire tube 309 will be crimped into the bayonet at the upper end opening of the terminal and the crimping operation will be completed.

[0037] Furthermore, when the hinge plate 303 presses down on the fixed plate 302, the pressing block 214 on the fixed plate 302 presses the wire 10 tightly against the lower end of the U-shaped groove block 215, preventing the wire 10 from shifting during the terminal crimping process, thereby affecting the crimping accuracy.

[0038] II. Cutting:

[0039] Then, the drive turntable 301 rotates the head end of the wire 10 of the crimped terminal from the crimping station 30 to the cutting station 20. During the rotation, the top of the pressure plate 312 is no longer under force. Under the elastic action of the return spring 313, the hinge plate 303 and the wire 10 on it are lifted relative to the fixed plate 302, and the wire 10 is no longer pressed. When the wire 10 turns back to the conveying direction (the conveying direction of the guide component is consistent with the wire direction of the guide mechanism 2), the drive motor 307 drives the wire 10 to be conveyed a certain distance in the direction of the cutting device, and the cutting device cuts the wire 10 of a fixed length.

[0040] The present invention enables the automatic clamping and loosening of the wire 10 during the rotation of the turntable 301 between the tangent station 20 and the crimping station 30. When the wire 10 is clamped, displacement of the wire 10 during the crimping process can be avoided, thereby improving the accuracy of the crimping. When the wire is not clamped, the wire 10 parallel to the conveying direction can achieve smooth adjustment of the cutting length of the wire 10.

[0041] During the rotation of the wire, the height angle can be automatically adjusted. When the wire 10 rotates to the crimping station 30, the guide is first positioned above the terminal card interface, and the positioning of the wire relative to the terminal is completed during the pressing process. During the lifting process of the wire 10 moving away from the crimping station 30, the wire connecting the terminal can be pulled away from the terminal carding station. The device of the present invention improves the efficiency of wire terminal crimping and wire feeding as a whole.

[0042] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
