Description

Technical Field

[0001] The device relates to the field of electronic product processing machinery, and specifically is a manual wire cutting device for a network filter. Background Art

[0002] In the network filter manufacturing process, winding the enameled wire onto the inner pins is a critical step. However, the traditional method of cutting the enameled wire is to manually cut the wire using stainless steel tweezers during the winding process. Some mechanical devices are also used, but various problems arise during use, resulting in a large number of poor quality and high scrap rates. Currently, the main problems with both manual and existing mechanical devices are: ① Manual cutting of the enameled wire using stainless steel tweezers is inefficient and significantly affected by human factors, which can easily lead to quality issues such as burrs and looseness; ② Existing mechanical devices are inefficient and have low versatility. They can only be used for a single product and are also significantly affected by human factors, which can easily lead to various quality issues such as burrs, looseness, over-cutting, under-cutting, and can cause tinning during subsequent immersion tinning. Summary of the Invention

[0003] To address the above issues, a technical solution is proposed: a manual tangent device for a network filter, comprising a base, left and right sliders that can slide horizontally on the base, a slide mechanism that can swing up and down using a bearing mounted on the base as a pivot point, pressure rods mounted on either side of the slide mechanism driven by a semi-circular slider, and a slider mechanism that can move horizontally on a crossbar. The device is characterized in that a longitudinal groove is provided on the upper end surface of the base, and a base for securing the bearings is provided at one end of the base. Two sets of bearings are positioned opposite each other. The left and right sliders are positioned within the grooves on the upper end surface of the base. A tightening screw extending horizontally through the grooves of the base adjusts and secures the left and right sliders, respectively. The outer surfaces of the left and right sliders are inclined, and each has a lower anti-slip strip on its inclined surface, opposite the upper anti-slip strip. The slider mechanisms are paired and mirror-imaged on either side of the horizontal vertical bar, flexibly connected to each other via a steel wire rope mounted on a fixed pulley.

[0004] The sliding rod frame mechanism is arranged at the upper end of the base and includes: a horizontal vertical rod, a cross rod, a support leg, a fixed pulley, a handle, a pressure strip, and a support rod. The two cross rods are fixedly connected to a horizontal vertical rod. The left cross rod extends outward to form an axis and is movably connected to two sets of bearings. The right cross rod extends outward to form a handle. The inner side surfaces of the two cross rods are provided with sliding grooves. A fixed pulley is provided in the middle of the upper end surface of the left cross rod, and a support leg is provided on the lower end surface of the right cross rod. The support rods are fixed and arranged parallel to both sides of the horizontal vertical rod. The pressure strip is arranged below the horizontal vertical rod and can be vertically displaced up and down at both ends of the horizontal vertical rod. A rubber pad is fixedly provided through the lower end surface of the pressure strip. The semi-moon sliders are paired and mirrored and movably connected to the two ends of the support rods at both ends of the slide rod frame mechanism. There are arc-shaped sliding holes in the middle of the two semi-moon sliders, and their outer ends are fixedly connected to two pressure rods parallel to the support rods. The lower end surface of the pressure rod is penetrated by an upper anti-slip strip. The inner ends of the two semi-moon sliders are movably connected to each other by a connecting rod, and a connecting rod spring is provided between the connecting rod and the handle.

[0005] The slider mechanism is set between the two horizontal bars and is parallel to the horizontal vertical bar. It includes: a needle roller slider, a slide bar, a knife groove, a blade, a paddle, and a handle. The needle roller slider can slide on the slide bar.

The paddle is provided. The handle is provided on the upper end face of the needle roller slider. A reset spring is fixed on one side of the needle roller slider, and the other end of the reset spring is fixed to one end of the slide bar. Several groups of slider mechanisms can be set in pairs and mirrored on both sides of the horizontal vertical bar on the inner side of the horizontal bar. The movement direction of the slider mechanism on the right is: from the bearing to the handle, and the movement direction of the slider mechanism on the left is opposite to that of the slider mechanism on the right.

DETAILED DESCRIPTION

[0014] The following is a clear and complete description of the technical solutions, operating methods and processes in the embodiments of the present device in conjunction with the drawings in the embodiments of the present device. Obviously, the described embodiments are only part of the embodiments of the present device, rather than all the embodiments. Based on the embodiments of the present device, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present device.

[0015] A manual tangent device for a network filter comprises a base 1, a left slider 3 and a right slider 4 that can slide horizontally on the base 1, a slide bar mechanism 7 that can swing up and down with a bearing 2 mounted on the base 1 as its pivot point, a pressure rod 9 mounted on either side of the slide bar mechanism 7 driven by a semi-circular slider 8, and a slider mechanism 13 that can move horizontally on a crossbar 702. The device is characterized by a longitudinal slot on the upper end surface of the base 1, a base for securing the bearing 2 at one end of the base 1, and two sets of bearings 2 positioned opposite each other. The left and right sliders 3 and 4 are positioned within the slot on the upper end surface of the base 1, and a tightening screw 5 extends horizontally through the slot of the base 1 to adjust and secure the left and right sliders 3 and 4, respectively. The outer surfaces of the left and right sliders 3 and 4 are inclined, and each has a lower anti-slip strip 6 positioned opposite the upper anti-slip strip 10 on its inclined surface. The slider mechanisms 13 are arranged in pairs, mirror images, on either side of a horizontal vertical bar 701 and are flexibly connected to each other via a steel wire rope 15 mounted on a fixed pulley 704.

[0016] The slide frame mechanism 7 is located at the top of the base 1 and comprises a horizontal vertical bar 701, a cross bar 702, support legs 703, a fixed pulley 704, a handle 705, a pressure strip 706, and support rods 707. Two cross bars 702 are fixedly connected to one horizontal vertical bar 701. The left cross bar 702 extends outward to form an axis and is movably connected to two sets of bearings 2. The right cross bar 702 extends outward to form a handle 705. Slide grooves are provided on the opposing inner surfaces of the two cross bars 702. A fixed pulley 704 is provided in the middle of the upper end surface of the left cross bar 702, and two support legs 703 are provided on the lower end surface of the right cross bar 702. The support rods 707 are fixed and parallel to either side of the horizontal vertical bar 701. The pressure strip 706 is located below the horizontal vertical bar 701 and can move vertically up and down at both ends of the horizontal vertical bar 701. A rubber pad is fixedly provided through the lower end surface of the pressure strip 706. The semi-moon sliders 8 are paired and mirrored and movably connected to the two ends of the support rod 707 at both ends of the slide frame mechanism 7. There are arc-shaped sliding holes in the middle of the two semi-moon sliders 8, and their outer ends are fixedly connected to two pressure rods 9 parallel to the support rod 707. The lower end surface of the pressure rod 9 is penetrated by an upper anti-slip strip 10. The inner ends of the two semi-moon sliders 8 are movably connected to each other by a connecting rod 11, and a connecting rod spring 12 is set between the connecting rod 11 and the handle 705.

[0017] Slider mechanism 13 is positioned between two horizontal bars 702 and parallel to horizontal vertical bars 701. It comprises a needle roller slider 1301, a slide bar 1302, a knife groove 1303, a blade 1304, a paddle 1305, and a handle 1306. Needle roller slider 1301 slides on slide bar 1302. Knife groove 1303 is tilted toward the product side of needle roller slider 1301. A replaceable, single-sided open blade 1304 with the same inclination is located within knife groove 1303. Paddle 1305 is positioned on the bottom end of needle roller slider 1301, facing toward knife groove 1303. Handle 1306 is located on the top end of needle roller slider 1301. A return spring 14 is fixed to one side of needle roller slider 1301, the other end of which is fixed to one end of slide bar 1302.

[0018] Several sets of slider mechanisms 13 are mounted in pairs and mirror images on either side of the horizontal vertical bar 701 on the inner side of the crossbar 702. The right slider mechanism 13 moves from the bearing 2 toward the handle 705, while the left slider mechanism 13 moves in the opposite direction. One end of the paddle 1305 is bolted to the bottom surface of the needle roller slider 1301, while the other end tilts downward and curls outward. The movement of the slider frame mechanism 7, slider mechanism 13, and connecting rod 11 can be fully automated by adding a motor or pneumatic cylinder.

[0019] The manual operation process is as follows:

[0020] 1. Preparation: ① Adjust the product placement height so that the bottom end of the product's internal PIN pin is level with the top end of the left and right sliders 3 and 4. ② Adjust the spacing between the left and right sliders 3 and 4 to ensure stable product placement. ③ Adjust the height of the hold-down bar 706 so that it can hold the product in place when horizontal. ④ Adjust the position of the slider mechanism 13 within the grooves of the two crossbars 702 and tighten it so that the height of the blade 1304 is lower than the enameled wire on the internal PIN pin and the distance between the blade 1304 and the internal PIN pin is less than the diameter of the internal PIN pin.

[0021] 2. Start working: Place the product with unbroken enameled wire between the left slider 3 and the right slider 4, half-grip the handle 705 with your left hand, and drive the slide frame mechanism 7 to press downward with the bearing 2 as the rotation point until the rubber pad on the lower end surface of the pressure strip 706 completely presses the upper end surface of the product, and the two support legs 703 are in full contact with the upper end surfaces of the left slider 3 and the right slider 4. At this time, half-grip the left hand and then fully grip the connecting rod 11, allowing the connecting rod 11 to move closer to the handle 705. As the connecting rod 11 moves towards the handle 705, it drives the half-moon slider 8 to slide with the two ends of the support rod 707 as the fulcrum, and then drives the two pressure rods 9 to move outward and downward, so that the upper anti-slip strips 10 on the lower end surfaces of the two pressure rods 9 contact the lower anti-slip strips 6 on the outer inclined surfaces of the left slider 3 and the slider 4, clamping the enameled wire on both sides of the product and straightening and tightening it. At this point, the product and the enameled wires on both sides of the product are fixed. With your right hand, push the handle 1306 on the slider mechanism 13 on the right side of the horizontal vertical rod 701, driving the needle roller slider 1301 to slide along the slide rod 1302 from the bearing 2 toward the handle 1306. During the sliding process, the blade 1304 cuts the enameled wire, and the paddle 1305 behind the blade 1304 smoothes the enameled wire ends on the inner pins. Because the slider mechanism 13 on the right side of the horizontal vertical rod 701 is flexibly connected to the slider mechanism 13 on the left side via the wire rope 15 and the fixed pulley 704, as the slider mechanism 13 on the right side of the horizontal vertical rod 701 slides, the slider mechanism 13 on the left side of the horizontal vertical rod 701 simultaneously completes the wire cutting and wiping work in the same working manner and in the opposite sliding direction. At this point, the wire trimming process is complete. The left hand switches from a full grip to a half grip, releasing connecting rod 11. Connecting rod spring 12 automatically resets connecting rod 11, and reset spring 14 automatically returns the needle roller sliders 1301 of the slider mechanism 13 on both sides to their starting positions. Simultaneously, the upper anti-slip strip 10 and the lower anti-slip strip 6 disengage, and the scrapped enameled wire falls along the outer inclined surfaces of the left and right sliders 3 and 4. At this point, the half-gripped left hand lifts the lifting handle 705 upward, and the right hand removes the finished enameled wire, smoothing the wire ends from the inner pins. This completes one cycle, and the next begins.

[0022] Beneficial effects

[0023] ① Improve efficiency: This device can reduce manual workload, save manual wire breaking time, and increase production. ② Improve quality: Manual wire breaking will inevitably lead to various problems such as thread ends, burrs, loose coils, etc., which will increase the workload of quality inspection. It will also cause a large amount of tin connection, excessive tin packages, poor tinning, etc. during the later tinning process. This device clamps and straightens the enameled wire through the upper anti-slip strip 10 and the lower anti-slip strip 6 on the lower end face of the pressure rod 9. When cutting the enameled wire, the paddle 1305 set behind the blade 1304 is used to smooth the thread ends. After cutting, this device has no burrs, no wire ends, no loose coils, and other problems. ③ Simple operation and efficient output: This device is simple and easy to operate. Ordinary workers with no disabilities in their hands can operate it. At the same time, the needle roller sliders 1301 on both sides of the product drive the other side to work simultaneously by sliding on one side, greatly improving efficiency. ④ High versatility: The left slider 3, right slider 4, pressure rod 9, and slider mechanism 13 of this device are all adjustable, meeting the needs of all products on the market with non-curved inner pins, including single, multiple, single-row, and multi-row inner pins. ⑤ Multi-purpose: This device is suitable for both manual winding and automatic winding machine tangent operations.
