Description

Technical Field

[0001] This utility model relates to the technical field of copper lead wire heading machines, specifically a wire feeding device for a copper lead wire heading machine. Background Technology

[0002] With the development of technology, electronic components are being used more and more, such as diodes and capacitors. Leads are the wires that extend from the inside out of electronic components. The length, precision, and flatness of the lead surface directly affect the product quality of molded electronic components.

[0003] After the wire is formed, the cutting device needs to be controlled to cut the wire. However, when using the traditional cutting device, the clamping block mold holding the wire needs to be opened before the cutting device is controlled to cut it. This method is cumbersome and makes it difficult to control the accuracy of the lead wire length, which affects the quality of the product.

[0004] As disclosed in Chinese Patent CN218982991U, a wire heading machine straightens the wire by feeding it into a straightening device, then feeding it into a wire feeding device. When the wire passes through a cutting mechanism and reaches a suitable length, a motor, a second rotating wheel, and a belt drive a large rotating wheel to rotate, which in turn drives a rotating rod to rotate cams one and two. First, cam two contacts a third rotating wheel on the side away from the threaded rod, causing a lever mounted above it to move a fixed block on one side forward. This moves the moving block forward, causing the heading device to head the wire. Then, a reset spring is used. Spring 2 resets the wire, while cam 1 contacts wheel 1. Through connecting rod 1, connecting rod 2, and connecting rod 3, the movable plate moves downward, thereby driving the cutting blade to cut the wire. After cutting, spring 1 resets the movable plate, and cam 2 rotates to the other side, contacting another wheel 3. This moves the lever installed on one side of the wheel, which in turn moves another fixed block, causing another moving block to move closer to the threaded rod. The rotating block rotates, causing the movable clamping block to move away from the wire, thereby moving a lever installed above it to feed the wire, so that the headed wire falls onto the feeding trough for feeding.

[0005] However, in the existing copper wire heading machine, the wire feeding device is not convenient for replacing and limiting the wire feeding wheel. At the same time, it lacks a guiding structure for the copper wire, making it difficult to guide the heading machine to feed the wire accurately.

[0006] Therefore, we urgently need to provide a wire feeding device for a copper lead wire heading machine. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides a technical solution:

[0029] Example 1:

[0030] A wire feeding device for a copper lead wire heading machine includes a support leg 1, a wire feeding guide structure on the top left side of the support leg 1, a wire exit structure in the middle of the top surface of the support leg 1, and a heading structure on the top right side of the support leg 1.

[0031] The wire feeding guide structure includes a wire feeding unit and a guide unit. The guide unit is installed on the top right side of the wire feeding unit. The wire feeding unit includes a wheel frame 101. A limit strip 102 is installed on the top of the wheel frame 101. A limit plate 103 is connected to the outer surface of the limit strip 102. A wire reel 104 is connected to the middle of the bottom surface of the limit plate 103. A fixing bolt 105 is installed near the left end of the middle of the top surface of the limit plate 103. The guide unit includes a mounting plate 106. A slide cylinder 107 is installed in the middle of the mounting plate 106. A slide rod 108 is connected to the end of the slide cylinder 107 away from the mounting plate 106. A spring 109 is connected to the end of the slide cylinder 107 near the slide rod 108. A limit block 110 is installed in the middle of the outer surface of the slide rod 108. A limit ring 111 is connected to the end of the slide rod 108 away from the slide cylinder 107. A fixing rod 112 is installed on the right end of the mounting plate 106. A limit ring 113 is connected to the two fixing rods 112 near each other.

[0032] The bottom surface of the limiting plate 103 is slidably connected to the top of the wheel frame 101, the outer surface of the wire reel 104 is rotatably connected to the inner wall of the limiting groove in the middle of the top surface of the wheel frame 101, the left end of the mounting plate 106 is fixedly connected to the top right side of the wheel frame 101, and the end of the spring 109 away from the slide cylinder 107 is fixedly connected to the outer surface of the limiting block 110.

[0033] By setting up the wire feeding structure and installing the limiting plate 103, the wire reel 104 can be limited, making it easy to replace the wire reel 104. At the same time, the wire output direction is limited by the first limiting ring 111 and the wire output direction is limited a second time by the second limiting ring 113, making the wire output more stable.

[0034] By placing the wire reel 104 inside the groove at the top of the reel frame 101, and then using the sliding connection between the limiting plate 103 and the limiting strip 102, the wire reel 104 is limited. The limiting plate 103 is detachably limited and fixed by the fixing bolt 105, which facilitates the assembly and disassembly of the wire reel 104. During the wire output process, the wire output is limited by the limiting ring 111. During the limiting process, the sliding rod 108 slides inside the sliding cylinder 107. During the sliding process, the limiting block 110 compresses the spring 109. The stress generated by the compression of the two springs 109 keeps the limiting ring 111 as close to the center line position as possible, thereby ensuring the accurate delivery of copper wire. At the same time, the copper wire is limited by the limiting ring 113, thereby further ensuring the stability of the copper wire output.

[0035] Example 2:

[0036] Based on Embodiment 1, the cable exit structure includes a workbench 205. A support frame 201 is installed in the middle of the top surface of the workbench 205. A lower wheel 202 is installed near the bottom of the support frame 201, and an upper wheel 203 is installed near the top of the support frame 201. An asynchronous motor 204 is detachably installed on the top front of the support frame 201. The bottom surface of the workbench 205 is fixedly connected to the top of the support leg 1. The outer surface of the lower wheel 202 abuts against the outer surface of the upper wheel 203. Grooves are formed in the middle of the outer surfaces of the lower wheel 202 and the upper wheel 203. The output end of the asynchronous motor 204 is connected to the upper wheel 203.

[0037] The heading structure includes a support rod 301, a frame 302 mounted on the top of the support rod 301, a processing table 303 mounted in the middle of the top surface of the bottom of the frame 302, an output rod 304 mounted in the middle of the bottom surface of the top of the frame 302, an output head 305 mounted on the output end of the output rod 304, and an operation box 306 mounted on the top of the frame 302. The bottom end of the support rod 301 is fixedly connected to the middle of the top surface of the worktable 205 near the right end, the bottom surface of the processing table 303 is fixedly connected to the bottom of the frame 302, and the output head 305 is detachably connected to the output rod 304.

[0038] By using the outgoing wire structure, the lower wheel 202 and the upper wheel 203 abut against each other and rotate, and the grooves on the outer surfaces of the lower wheel 202 and the upper wheel 203, the direction of the outgoing wire can be limited and guided, making the direction of the copper wire outgoing wire more accurate.

[0039] During the wire feeding process, the asynchronous motor 204 is started to drive the upper wheel 203 to rotate. The upper wheel 203 and the lower wheel 202 abut against each other, so that the upper wheel 203 rotates and drives the lower wheel 202 to rotate together. The grooves on the outer surfaces of the lower wheel 202 and the upper wheel 203 are used to convey the copper wire, thereby achieving the effect of wire feeding. The two sets of wire feeding structures limit the transmission of the copper wire, thereby effectively ensuring the accuracy of wire feeding. Afterwards, the heading structure is used to head the copper wire.
