Description

Technical Field

[0001] The invention relates to mechanical equipment for manufacturing filters, and in particular to a filter paper end cover positioning fixture used in the production of filter elements. Background Art

[0002] Currently, automotive filters typically include a housing, a filter element assembly, a screw-type plate, a check valve, and a bypass valve. The filter element assembly consists of end caps (upper and lower), filter paper, and a center tube. The filter paper is cylindrical with a hollow center (for accommodating the center tube). The end caps are ring-shaped and made of metal (or plastic), referred to as metal end caps (or plastic end caps). These end caps consist of two pieces, upper and lower, that attach to the top and bottom of the filter paper, respectively. These end caps are typically manufactured using glue or heating (using a lamp or heating wire). Currently, non-woven fabric end caps (instead of metal or plastic end caps) are typically used. Ultrasonic welding is required to position the non-woven end caps and filter paper using high-frequency ultrasonic friction to generate heat. This process involves manual or semi-automated equipment, with manual operation required at times. This results in a low degree of automation, poor efficiency, and difficult-to-guaranteed processing quality. Summary of the Invention

The non-woven fabric end cap lifting assembly includes a linear lift transmission module mounted on the loading rack, a lifting fork, and an end cap positioning sleeve. The lifting fork is positioned on the bottommost non-woven fabric end cap and lifts it linearly.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 、 Figure 2As shown, the present invention is applied to the filter paper end cap positioning fixture for filter element production, comprising a frame 1, a turntable rotating mechanism 10 (including a turntable and a turntable rotation control component, which is a well-known technology), a plurality of groups of flip bearing seats 20 are installed on the periphery of the turntable 11 of the turntable rotating mechanism 10, the flip bearing seats 20 are connected to the tool assembly frame 22 through a flip shaft 21, a material discharge opening and closing component is installed in the tool assembly frame 22, one side of the tool assembly frame 22 is movably connected to the tool positioning shaft 23, and the tool positioning shaft 23 is mounted on the tool through a positioning shaft mounting frame 24. The periphery of the turntable 11 is supported by a fixed, non-rotating support plate 13 (located at its center via support rods 12). A set of fixture positioning assemblies 3 are mounted on this support plate 13. These assemblies include a fixture positioning fork 31 mounted above the fixture positioning shaft 23. This fork 31 is connected to a fork lateral movement power source 32 (a fork lateral movement cylinder), which in turn is connected to a fork lift power source 33 (a fork lift cylinder), which is mounted on the support plate 13. The center of the turntable 11, which does not rotate, houses the control unit.

[0017] The unloading opening and closing assembly includes a filter paper clamping movable block 26 (located on the outside) mounted within a tooling assembly frame. The tooling assembly frame has an internal groove 221 that interfaces with the filter paper clamping movable block 26 (with a groove). The two interfaces form the filter paper shape and serve to position the filter paper. Both the internal groove 221 of the tooling assembly frame 22 and the filter paper clamping movable block 26 are equipped with end cap positioning pieces 25 (the two pieces are positioned opposite each other and each has a groove that interfaces with each other to position the end cap and filter paper). The filter paper clamping movable block 26 is connected to the outside of the tooling assembly frame 22 via two movable block guide rods 27 (located on either side) and a single unloading opening and closing shaft 28 (located in the center). A compression spring 29 is mounted on the movable block guide rods 27. The movable block guide rods 27 and the unloading opening and closing shaft 28 are arranged side by side and in the same row. The space formed between the two end cover positioning pieces and between the inner groove 221 and the filter paper clamping moving block 26 can just accommodate the upper and lower combination of the non-woven fabric end cover and the filter paper.

[0018] A flip-in-place sensing piece 34 is installed on the tail of the flip shaft 20, and a positioning sensor 35 is installed on the support plate 13 and on the side of the tooling fixture positioning assembly 3. The flip-in-place sensing piece 34 can rotate as the flip shaft 21 flips, and the turntable rotates to make the flip-in-place sensing piece 34 correspond to the positioning sensor 35, thereby sensing the horizontal degree of the tooling assembly frame after flipping (it cannot be tilted, if it is tilted, the tooling positioning shaft cannot be inserted into the tooling assembly frame), that is, the tooling fixture flipping mechanism works to flip the tooling assembly frame and the flip shaft into place, so as to prepare for the tooling positioning fork of the tooling fixture positioning assembly 3 to reinsert the tooling positioning shaft into the tooling assembly frame.

[0019] like Figure 1 、 Figure 2 As shown, the fully automatic ultrasonic welding machine for non-woven fabric end caps and filter paper used in the present invention is equipped with a filter paper discharging fixture opening and closing mechanism 4, a first non-woven fabric end cap feeding mechanism 5, a first welding mechanism 6 (including a cooling air blower 67), a fixture flipping mechanism 7, a second non-woven fabric end cap feeding mechanism 15, a second welding mechanism 16, and a finished end cap filter paper discharging mechanism 8 (including a finished product receiving assembly 89) in sequence on the outer periphery of the turntable 11 (on the frame, support plate, or outside the frame) and at the positions corresponding to the filter paper end cap positioning fixture 2 (above, below, or to the side thereof). The turntable rotating mechanism 10, the filter paper discharging fixture opening and closing mechanism 4, the first non-woven fabric end cap feeding mechanism 5, the first welding mechanism 6, the fixture flipping mechanism 7, the second non-woven fabric end cap feeding mechanism 15, the second welding mechanism 16, and the finished end cap filter paper discharging mechanism 8 are all electrically connected to a microcomputer control mechanism 9 for unified control. The second non-woven fabric end cover feeding mechanism 15 has the same structure as the first non-woven fabric end cover feeding mechanism 5 , and the second welding mechanism 16 has the same structure as the first welding mechanism 6 .

[0020] Through the automatic intermittent rotation of the turntable rotating mechanism 10 and its turntable 11, the tooling assembly frame 22 and the discharge opening and closing component, the tooling fixture positioning component 3, and the filter paper discharge tooling opening and closing mechanism 4 complete the discharge, clamping, and positioning of the filter paper in sequence, the first non-woven fabric end cover feeding mechanism 5 completes the feeding of the non-woven fabric end cover on the filter paper (i.e., the initial feeding), the first welding mechanism 6 completes the welding combination of the filter paper and the non-woven fabric end cover, the tooling fixture flipping mechanism 7 completes the flipping of the tooling assembly frame 22 and flattens the filter paper, and the second non-woven fabric end cover feeding mechanism 15 completes the feeding of the non-woven fabric end cover on the flipped filter paper (i.e., the second feeding), the second welding mechanism 16 completes the second welding combination of the filter paper and the non-woven fabric end cover, and the end cover filter paper finished product discharging mechanism 8 completes the finished product discharging, thereby fully automatically completing the whole process of welding the filter paper and the non-woven fabric end cover to form a finished filter element. The discharge opening and closing components are installed in the tooling assembly frame 22, with one set on the left and one on the right, corresponding to the discharge opening and closing of the filter paper discharge tooling opening and closing mechanism 4, the first end cover feeding of the non-woven fabric end cover first feeding mechanism 5, the first end cover filter paper welding of the first welding mechanism 6, the flattening and turning down of the tooling fixture flipping mechanism 7, the second end cover feeding of the non-woven fabric end cover second feeding mechanism 15, the second end cover filter paper welding of the second welding mechanism 16, the finished product discharging of the end cover filter paper finished product discharging mechanism 8 and other related process station operations are also two sets, thereby improving the end cover filter paper assembly volume and work efficiency.

[0021] like Figure 1 、 Figure 3 As shown, a filter paper unloading tooling opening and closing mechanism 4 is installed below the tooling assembly frame 22, and the filter paper unloading tooling opening and closing mechanism 4 includes a unloading lifting power source 41 (a unloading lifting cylinder, which is installed on the frame 1) installed below the tooling assembly frame 22, and the unloading lifting power source 41 is connected to a unloading lifting opening and closing seat 42 (longitudinal position), and a filter paper support plate 43 (facing inward, corresponding to the position of the end cover positioning piece and the filter paper clamping moving block) and a unloading opening and closing power source 44 (facing outward, a unloading opening and closing cylinder) are respectively installed on the unloading lifting opening and closing seat 42, and the unloading opening and closing power source 44 is connected to a unloading opening and closing fork 45 (lateral position) (through an opening and closing fork mounting plate 46), and the unloading opening and closing fork 45 is located below the unloading opening and closing shaft 28. The filter paper support plate 43 is mounted on the discharging lifting and closing base 42 via a height adjustment guide rod 47. A height adjustment knob 48 is mounted at the lower end of the height adjustment guide rod 47. By rotating the height adjustment knob 48, the height of the filter paper support plate 43 is adjusted by the height adjustment guide rod 47 to accommodate different filter paper specifications.

[0022] First, the tooling positioning shaft 23 is located on one side of the tooling assembly frame 22, so that the tooling assembly frame is positioned in a horizontal position. The turntable 11 rotates the tooling assembly frame 22 to the top of the filter paper feeding tooling opening and closing mechanism 4. The feeding lifting power source 41 and the feeding opening and closing power source 44 are started and the feeding fork mounting plate 46 is raised, and the feeding opening and closing fork 45 is driven to pull the feeding opening and closing shaft 28 on the tooling assembly frame 22 (along the moving block guide rod 27) outward, so that the filter paper clamping moving block 26 and the tooling assembly frame are clamped. The inner groove 221 and the two end cap positioning pieces are separated and opened, allowing the filter paper to be manually placed longitudinally between the filter paper clamping movable block 26 and the inner groove 221 and between the two end cap positioning pieces. The filter paper is supported from the bottom by the filter paper support plate 43. Then, the material discharge opening and closing fork 45 is released, and the filter paper clamping movable block 26 and the inner groove 221 and the two end cap positioning pieces 25 are automatically closed and clamped by the compression spring 29 on the movable block guide rod 27. Then, the turntable rotates the tooling assembly frame 22 with the filter paper to the position of the first non-woven end cap feeding mechanism 5.

[0023] like Figure 1 、 Figure 4 、 Figure 5 As shown, a first non-woven fabric end cover feeding mechanism 5 is installed on the outer periphery of the turntable 11 and on the side of the filter paper feeding tool opening and closing mechanism 4, including a feeding rack 50, on which are mounted non-woven fabric end cover storage components 51 that are docked with each other (including a storage turntable 512 mounted on the feeding rack 50, a plurality of circumferentially arranged storage rods 511 mounted on the periphery of the storage turntable, etc., the storage rods 511 are sleeved with non-woven fabric end covers 14 stacked up and down), a non-woven fabric end cover lifting component 52 (including a linear lifting transmission module 522, a lifting fork 521, an end cover positioning sleeve 523, etc. mounted on the feeding rack 50, the lifting fork 521 is on the bottom non-woven fabric end cover and lifts it linearly together, and the non-woven fabric end cover lifted into place enters the end cover positioning sleeve 523 for positioning), a non-woven fabric end cover grabbing and transferring component 53, the non-woven fabric end cover grabbing and transferring component 53 (such as Figure 5As shown) includes a transfer power source 531 (a transfer cylinder) installed on the loading rack 50, and the transfer power source 531 is connected to the grabbing mounting plate 532 (horizontal position), and a grabbing lifting power source 533 (a grabbing lifting cylinder) is installed on the grabbing mounting plate 532, and the grabbing lifting power source 533 is connected to the grabbing power source 534 (a grabbing cylinder) (longitudinal position), and the grabbing power source 534 is connected to the grabbing claw 535 (longitudinal position), and the grabbing claw 535 is a needle-shaped, expandable and retractable type, and a stripping plate 536 is installed on the periphery of the grabbing claw 535, and the stripping plate 536 is connected to the stripping power source 538 (a stripping cylinder, which is installed on the grabbing lifting power source 533) through a stripping guide rod 537. The lifting fork 521 is connected to a linear lifting transmission module 522 (comprising a linear lifting power source and a lifting transmission assembly). The end cap positioning sleeve 523 is mounted on the loading rack 50, above the storage rod 511 and to the side of the transfer power source 531. The grab claw 535 is positioned above the end cap positioning sleeve 523. The linear lifting transmission module 522 controls the lifting fork 521 to linearly lift the stacked non-woven fabric end caps 14 on the storage rod 511. The stacked non-woven fabric end caps 14 on the storage rod 511 of the non-woven fabric end cap storage assembly 51 are lifted one by one by the lifting fork 521 and placed into the end cap positioning sleeve 523 (multiple pieces at a time). Then, the grabbing and lifting power sources 533 and 534 of the non-woven end cap grabbing and transferring assembly 53 are activated, and the grasping claw 535, which has been lowered into position, reaches the end cap positioning sleeve 523 and spreads out in a needle-like manner at the center of the non-woven end cap, grabbing it from its inner wall (one piece at a time), and then rises. Then, the transfer power source 531 carries the grabbing mounting plate 532 and the non-woven end cap to the filter paper in the filter paper end cap positioning fixture 2. The grasping claw 535 descends and is activated by the stripping power source 538, driving the stripping plate 536. At the same time, the grasping claw 535 is released, and the non-woven end cap is placed on the filter paper already installed in the filter paper end cap positioning fixture. Then, the turntable rotates the fixture assembly frame 22 with the filter paper and non-woven end cap to the position of the first welding mechanism 6.
