Detailed Implementation

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] like Figure 1 As shown, the improved duster head includes a main body a and two branched parts b (both made of non-woven fabric). Both sides of the main body a are covered with fluff c. The branched parts b are connected to the end edges d of the main body a, and fluff c is fixed to the opposing surfaces of the two branched parts b.

[0020] The difference between the duster head to be processed 8 and the improved duster head is that the two forked parts b have no fixed fluff c on their opposite surfaces. Example

[0021] The embodiment of the duster fork lint welding device includes a platform 1, a filament clamping mechanism 2, and a thermal bonding mechanism 3; the filament clamping mechanism 2 is removably disposed above the platform 1 and includes a first clamping member 201 and a second clamping member 202 spaced apart along a first direction; the thermal bonding mechanism 3 has a welding head opposite to the platform 1; the platform 1 has a plurality of unit placement areas arranged sequentially along the first direction, each unit placement area has a narrow opening 102, and a pair of duster clamping members 4 are fixedly connected to the unit placement area below the platform, the pair of duster clamping members 4 having a main duster body clamping space communicating with the narrow opening 102; the unit placement area includes two fork placement areas 101, the two fork placement areas 101 of the same unit placement area are symmetrically disposed on both sides of the length direction of the narrow opening 102.

[0022] The platform 1 provides a stable bearing surface for the junction of the forked portion b and the filament c. The first clamping member 201 and the second clamping member 202 of the filament clamping mechanism 2 respectively clamp the two ends of the filament 7. The filament clamping mechanism 2 has a welding station located between the welding head 12 and the platform 1 and a wire picking station located between the filament feeding mechanism 2. The displacement driving mechanism between the welding station and the wire picking station includes, but is not limited to, a linear driving mechanism such as a slide table or a robot. The thermal bonding mechanism 3 can be selected as thermal bonding or ultrasonic welding. The shape of the welding area and the arrangement of the welding heads are specifically determined according to the location of the dust piercing and the filament 3. The shape of a single welding area can be selected as a dot or a line.

[0023] Specifically, such as Figure 2 , Figure 5 , Figure 6 As shown, the platform 1 has multiple elongated openings 102 arranged in a straight line (along a first direction), and the two sides of the elongated openings 102 in the length direction of the platform 1 are forked portion placement areas 101. A pair of clamping dusters 4 are fixedly connected below the platform surface of the platform 1. The pair of clamping dusters 4 are used to clamp the main body a of the duster head 8 to be processed. Figure 2 The middle section consists of a pair of clamping folding plates.

[0024] In this embodiment, when the duster fork section fluff welding device is working, the fork section b of the duster head 8 to be processed is attached to the fork section placement area 101 on the table, and the main body a of the duster head 8 to be processed is clamped between the paired duster clamps 4. The filament clamping mechanism 2 is used to clamp the filament 7 (the filament 7 becomes fluff c after being cut short) and place the filament 7 above the fork section b. In the standby state, the welding head of the heat bonding mechanism 7 is located above the filament 11 and is used to push the filament 11 towards the fork section b until the filament 11 is pressed against the fork section b.

[0025] The steps for using the duster fork welding device of the present invention include: S0: Place the main body a of the duster 8 to be processed between the pair of clamping duster parts 4, and attach the two forked parts b of the duster 8 to the two forked parts placement areas 101 of the table surface 1 respectively; S1: The filament clamping mechanism 2 clamps the filament 7 and places the filament 7 above the fork b; S2: The welding head 12 of the thermal bonding mechanism 3 presses the filament 7 against the welding surface of the fork b and then welds it to obtain a welded connection structure between the filament 7 and the fork b.

[0026] In another preferred embodiment, the unit placement area is square, and the sides of adjacent bifurcation placement areas 101 are parallel or adjacent.

[0027] After the filament 7 is welded to the branch section b, adjacent branch sections b of different duster bodies are connected by the filament 7. Separating adjacent branch sections b of different duster heads requires removing these filaments 7, and the shorter these filaments 7 are, the more beneficial it is to reduce the consumption of filament 7 (thereby reducing costs). The unit placement area is square, and at this time, the branch section placement area 101 is an isosceles right triangle. The sides of adjacent branch section placement areas 101 are parallel or adjacent, and at this time, several branch section placement areas 101 can be regarded as a rectangular welding area, which is beneficial to reduce the consumption of filament 7.

[0028] Understandably, after the welding of the filaments 7, the filaments 7 between adjacent duster heads and between two forked sections b within the same duster head must be sheared to obtain the fluff c. Compared to adjacent forked section placement areas 101 having adjacent edges, parallel arrangement of the edges of the forked section placement areas 101 can obtain longer fluff c.

[0029] In another preferred embodiment, a cutting assembly is also included. The cutting assembly includes a fixed blade holder 5 and a movable blade holder 6, and a cutting blade 9 connected to the fixed blade holder 5 and the movable blade holder 6 respectively. The fixed blade holder 5 is disposed between the filament clamping mechanism 2 and the platform 1. The welding head has a first orthographic projection on the platform, and the cutting blade 9 has a second orthographic projection on the platform. There is a clearance area between the first orthographic projection and the second orthographic projection.

[0030] Specifically, the cutting assembly is used to cut the filament 7 between adjacent forks b. For example... Figure 7 and Figure 8 As shown, the fixed blade holder 5 of the cutting assembly includes a blade holder body, a cylinder mounting base located above the blade holder body, and four guide rods 501 connecting the blade holder body and the cylinder mounting base. The movable blade holder 6 is disposed between the blade holder body and the cylinder mounting base and slides along the guide rods 501. The cylinder mounting base is fixedly connected to the cylinder 10, and the piston rod of the cylinder 10 is fixedly connected to the movable blade holder 6. The cylinder 10 is used to drive the movable blade holder 6 to slide along the guide rods 501, thereby realizing the cutting of the filament 7 by the upper and lower cutting blades 9.

[0031] The welding head 12 has a first orthographic projection on the table, and the cutter 9 has a second orthographic projection on the table. There is a clearance area between the first orthographic projection and the second orthographic projection so that the welding head 12 does not interfere with the cutter 9 when it is working.

[0032] The steps for using the duster fork welding device equipped with a cutting blade assembly include: S0: Place the main body a of the duster 8 to be processed between the pair of clamping duster parts 4, and attach the two forked parts b of the duster 8 to the two forked parts placement areas 101 of the table surface 1 respectively; S1: The cutter assembly moves above the forked part b, and the lower surface of the fixed cutter holder 5 and the upper surface of the forked part b are in contact. S2: The filament clamping mechanism 2 clamps the filament 7 and places the filament 7 above the fork b. At this time, the lower surface of the filament 7 and the upper surface of the cutter 9 of the fixed cutter 5 abut against each other. S2: The welding head 12 of the heat bonding mechanism 3 presses the filament 7 against the welding surface of the fork b and then welds it to obtain a welded connection structure between the filament 7 and the fork b. S3: The cutter assembly starts and cuts the filament 7 between adjacent forks b.

[0033] In another preferred embodiment, the welding heads opposite the bifurcation placement area 101 are spaced apart and there are more than two of them. The cutter 9 includes a duster cutter and a duster inner cutter.

[0034] Specifically, the inter-cutting blade is used to cut the filaments 7 between different branch placement areas 101, and the internal cutting blade is used to cut the filaments 7 located within the branch placement area 101.

[0035] In another preferred embodiment, the inner cutting blade connected to the fixed blade holder 5 includes a first cutting blade and a second cutting blade. The height of the first cutting blade is greater than the height of the second cutting blade along the direction perpendicular to the table surface. This differentiated height of the inner cutting blades results in different fluff lengths c between the central and edge areas of the forked portion b, thus adapting to different cleaning scenarios.

[0036] Specifically, the cutter 9 along the first direction is positioned between two adjacent welding points (the welding positions of the filament 7 and the forked portion b). When the distance between these two adjacent welding points is constant, the length of the filament between the two welding points depends on the length of the filament 7 connecting the two welding points. The lower surface of the filament 7 abuts against the cutter of the fixed cutter holder 5. The higher the inner cutter, the longer the length of the filament 7 between the two welding points.

[0037] In another preferred embodiment, the thermal bonding mechanism 3 includes a welding guide rail 11 extending along a first direction, and the welding head 12 moves along the first direction. The filament clamping mechanism 2 further includes a mounting base, a clamping drive, a first guide rail 203 fixedly connected to the mounting base and extending along the first direction, a first clamping member 201 fixedly connected to the mounting base, and a second clamping member 202 connected to the first guide rail 203. The clamping drive is configured to drive the second clamping member 202 to move along the first guide rail 203.

[0038] Specifically, such as Figures 2-5 As shown, the welding head 12 is connected to the welding guide rail 11 via a slide block that is slidably connected to the welding guide rail 11. The clamping drive unit drives the second clamping member 202 to move along the first guide rail 203, so the distance between the first clamping member 201 and the second clamping member 202 is adjustable.

[0039] Before welding, the welding section (non-clamped area) of the filament 7 only abuts against the upper surface of the cutter 9 of the fixed tool holder 5, and is in a taut and straight state. The welding head 12 moves along the first direction to weld the filament 7 sequentially in different bifurcation placement areas 101. At this time, the filament 7 alternately abuts against the upper surface of the bifurcation b and the upper surface of the cutter 9 of the fixed tool holder 5, requiring the filament to have a predetermined bending allowance. By adjusting the distance between the first clamping member 201 and the second clamping member 202 (the welding head 12 and the second clamping member 202 move synchronously), the filament is supplied according to the allowance required for each welding, ensuring that after the welding head presses the filament against the bifurcation, the other parts of the filament are in a taut and straight state, avoiding problems such as loosening and bending of the fibers and slight displacement of the fiber bundle width direction. The filaments are evenly distributed so that the fibers in the bifurcation have a predetermined distribution density.

[0040] In another preferred embodiment, a pair of second guide rails 13 extending along a first direction and parallel to each other are further included. Each second guide rail 13 is provided with a plurality of clamping units 14 arranged at intervals along the first direction. The clamping units 14 located on different second guide rails 13 have opposing clamping surfaces. The long side of the narrow opening 102 is the upper edge of the clamping surface. The bifurcated placement area 101 is coplanar with the upper surface of the clamping unit 14. At least one of the pair of second guide rails 13 is connected to a horizontal drive member, which is used to adjust the spacing between the second guide rails 13.

[0041] Specifically, such as Figure 9 As shown, two second guide rails 13 are respectively fixedly connected to a plurality of clamping units 14 arranged at intervals along a first direction. One of the two second guide rails 13 is connected to the slide of the lead screw slide module 15, and the other is connected to the slide seat of the lead screw slide module 15. When the slide slides, it causes the two second guide rails to move away from each other and closer together, so that the spacing between the clamping units 14 connected to the two second guide rails 13 is adjustable. This allows the main body to be placed between the pairs of clamping units 14 in conjunction with the main body bracket, and also facilitates the adjustment of the clamping force of the clamping units 14 on the main body a.

[0042] In another preferred embodiment, the clamping unit 14 includes a plurality of movable clamping units 1401 and a fixed clamping unit 1402 fixedly connected to the second guide rail 13. The second guide rail 13 is connected to a push-drive member 16, which is located on the side of the plurality of movable clamping units 1401 opposite to the fixed clamping unit 1402. The push-drive member 16 is configured to drive the plurality of movable clamping units 1401 to reciprocate along the second guide rail 13, and a flexible cable 17 is provided between two adjacent clamping units 14 connected to the same second guide rail 13.

[0043] Specifically, such as Figure 10 and Figure 11As shown, the pushing drive 16 is a cylinder used to drive the nearest clamping unit 14 to slide back and forth along the second guide rail 13. The flexible cable 17 is used to limit the distance between two adjacent clamping units 14 on the same second guide rail 13. At the clamping station, the pushing drive 16 on both second guide rails 13 simultaneously pushes all movable clamping units 1401 towards the fixed clamping unit 1402 until the movable clamping units 1401 abut against the fixed clamping unit 1402 (at this time, all clamping units 14 cannot move). At the pre-clamping station, the pushing drive 16 on both second guide rails 13 simultaneously pulls the closest movable clamping unit 1401 away from the fixed clamping unit 1402 until all the flexible cables 17 are taut. At this time, the main body a can be placed between the clamping units 14 connected to the two second guide rails 13 respectively. (At this time, the clamping space between the clamping units 14 is open along the first direction.) In another preferred embodiment, a vacuum pump and a negative pressure pipe are also included. The bifurcation placement area 101 is provided with a negative pressure through hole 1011, and the vacuum pump is connected to the negative pressure through hole through the negative pressure pipe.

[0044] Specifically, such as Figure 6 As shown, the negative pressure through-hole 1011 is a through-hole opened in the bifurcation placement area 101. The upper opening of the negative pressure through-hole 1011 faces the bifurcation b during operation. The lower opening of the negative pressure through-hole 1011 is connected to a negative pressure pipe, which is connected to a vacuum pump. During operation of the duster bifurcation lint welding device of this embodiment, the inside of the negative pressure through-hole 1011 is under negative pressure, and the bifurcation b located in the bifurcation placement area 101 is positioned within the bifurcation placement area 101 due to the negative pressure.

[0045] The embodiment also provides a method of using the duster fork lint welding device, including the following steps: S1: Place the main body of the duster into the main duster clamping space, press the two forked ends of the duster onto the forked end placement area, and combine the forked ends of multiple dusters to form a welding area extending along the first direction. S2: The filament clamping mechanism fixes the filament to the side opposite to the bifurcation section and between the platform and the welding head; S3: The welding head presses the filament against the welding surface of the fork and then welds it to obtain a welded connection structure between the filament and the fork.

[0046] It is understandable that the multiple dusters obtained in S3 are connected by filaments 7.

[0047] Furthermore, it also includes: S4: The cutting assembly cuts the filaments 7 between adjacent duster bodies and the filaments 7 between two welding points in the same fork b, resulting in multiple independent duster bodies.

[0048] Furthermore, S3 includes: S31: The welding head 12 moves along the welding guide rail 11, and the second clamping member 202 moves along the first guide rail 203 until the filament 7 has a relaxation amount that satisfies a single welding operation. S32: The welding head 12 pushes the filament towards the fork b until the filament 7 comes into contact with the cutter 9, thus welding the filament 7 to the fork b.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
