Description

Technical Field

[0001] This invention relates to machinery and equipment for manufacturing filters, and more specifically to a welding machine for end caps and filter paper used in the production of filter elements. Background Technology

[0002] Currently, automotive filters generally include components such as a housing, filter element assembly, screw plate, check valve, and bypass valve. The filter element assembly consists of end caps (divided into upper and lower end caps), filter paper, and a central tube. The filter paper is a hollow cylindrical product (used to house the central tube). The end caps are annular and made of metal (or plastic), hence the name metal end caps (or plastic end caps). These end caps consist of two pieces, upper and lower, which are respectively attached to the top and bottom of the filter paper. The bonding process generally involves gluing or heating (using lamps or heating wires). Currently, non-woven fabric end caps are being used (replacing metal or plastic end caps). This requires ultrasonic welding, which uses high-frequency ultrasonic friction to generate heat for feeding the filter paper, loading the end cap, welding (fusion), and unloading the finished product. This process is entirely manual or semi-automated, requiring manual operation in between. Its automation level is low, its efficiency is poor, and the processing quality is difficult to guarantee. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a fully automatic ultrasonic welding machine for nonwoven end caps and filter paper that can sequentially complete processes such as filter paper feeding and clamping, nonwoven end cap feeding, filter paper end cap welding, tooling fixture flipping, and finished product discharge, with a high degree of automation and no need for intermediate operation.

[0004] The objective of this invention is achieved through the following technical solution: a fully automatic ultrasonic welding machine for nonwoven fabric end caps and filter paper, comprising a frame and a turntable rotation mechanism. Several sets of filter paper end cap tooling fixtures are mounted on the periphery of the turntable. A support plate is mounted on the turntable, and a tooling fixture positioning assembly is mounted on the support plate. On the outer periphery of the turntable, corresponding to the positions of the filter paper end cap tooling fixtures, a filter paper feeding tooling opening and closing mechanism, a first nonwoven fabric end cap feeding mechanism, a first welding mechanism, a tooling fixture flipping mechanism, a second nonwoven fabric end cap feeding mechanism, a second welding mechanism, and an end cap filter paper finished product discharge mechanism are sequentially mounted.

The filter paper end cap tooling fixture includes a tilting bearing seat mounted on the periphery of the turntable. The tilting bearing seat is connected to the tooling assembly frame through a tilting shaft. A feeding opening and closing assembly is installed in the tooling assembly frame. One side of the tooling assembly frame is movably connected to a tooling positioning shaft. The tooling positioning shaft is mounted on the periphery of the turntable through a positioning shaft mounting bracket. The tooling fixture positioning assembly includes a tooling positioning fork mounted above the tooling positioning shaft. The tooling positioning fork is connected to a fork lateral movement force source. The fork lateral movement force source is connected to a fork lifting power source. The fork lifting power source is mounted on a support plate.

[0005] A flip-in sensing plate is installed at the tail of the flip shaft, and a positioning sensor is installed on the support plate and on the side of the tooling fixture positioning assembly. The feeding opening and closing assembly includes a filter paper clamping moving block installed in the tooling assembly frame. The tooling assembly frame has an inner groove that mates with the filter paper clamping moving block. End cap positioning plates are installed on the inner groove of the tooling assembly frame and on the filter paper clamping moving block. The filter paper clamping moving block is connected to the outside of the tooling assembly frame through the moving block guide rod and the feeding opening and closing shaft, respectively. A compression spring is installed on the moving block guide rod.

[0006] The filter paper feeding fixture opening and closing mechanism includes a feeding lifting power source installed below the filter paper end cap fixture fixture. The feeding lifting power source is connected to the feeding lifting opening and closing seat. The feeding lifting opening and closing seat is equipped with a filter paper support plate and a feeding opening and closing power source. The feeding opening and closing power source is connected to a feeding opening and closing fork. The feeding opening and closing fork is located below the filter paper end cap fixture fixture.

[0007] The first feeding mechanism for nonwoven end caps includes a feeding frame, on which are mounted a nonwoven end cap storage assembly, a nonwoven end cap lifting assembly, and a nonwoven end cap gripping and conveying assembly that are connected to each other. The nonwoven end cap gripping and conveying assembly includes a conveying power source mounted on the feeding frame, which is connected to a gripping mounting plate. A gripping lifting power source is mounted on the gripping mounting plate and is connected to the gripping power source. The gripping power source is connected to a gripping claw, which is a needle-shaped, extendable type. A stripping plate is mounted around the gripping claw, and the stripping plate is connected to the stripping power source through a stripping guide rod.

[0008] The first welding mechanism includes a welding frame. A transducer lifting and pressing power source is mounted on the top of the welding frame. A transducer and an ultrasonic welding head are connected below the transducer lifting and pressing power source. The ultrasonic welding head is connected to a cooler via a combination of a cold air cover and a cold air pipe connector. A filter element top plate is mounted below the ultrasonic welding head and is connected to an upper lifting power source. The tooling fixture flipping mechanism includes a flipping frame. A pressing and leveling power source is mounted on the top outer end of the flipping frame. A leveling block is connected to the pressing and leveling power source below the pressing and leveling power source via a leveling plate. A tooling flipping power source is mounted in the middle of the flipping frame and is connected to a clamping power source. The clamping power source is connected to a clamping block.

[0009] The end cap filter paper finished product discharging mechanism includes a discharging frame connected to a discharging lifting power source. A discharging opening and closing power source is mounted on one side of the discharging frame, connected to a discharging opening and closing fork.

[0010] By adopting the technical solution of this invention, the filter paper is fed, clamped, and positioned sequentially by the filter paper end cap tooling fixture and the filter paper feeding fixture opening and closing mechanism through the automatic intermittent rotation of the turntable. The nonwoven fabric end cap first feeding mechanism feeds the nonwoven fabric end cap onto the filter paper (i.e., initial feeding), the first welding mechanism welds the filter paper and the nonwoven fabric end cap together, the tooling fixture flipping mechanism flips and flattens the filter paper end cap tooling fixture, the nonwoven fabric end cap second feeding mechanism feeds the nonwoven fabric end cap onto the flipped filter paper (i.e., second feeding), the second welding mechanism welds the filter paper and the nonwoven fabric end cap together again, and the end cap filter paper finished product discharge mechanism discharges the finished product.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 8 As shown, the present invention relates to a fully automatic ultrasonic welding machine for nonwoven fabric end caps and filter paper used in the production of filter cartridges. It includes a frame 1 and a turntable rotation mechanism 10 (including a turntable and a turntable rotation control assembly, which are known technologies). Several sets of filter paper end cap tooling fixtures 2 are mounted around the turntable 11 of the turntable rotation mechanism 10. A support plate 13 (fixed and non-rotating) is mounted on the turntable 11 (its center position is supported by a support rod 12). Tooling fixture positioning assemblies 3 (as a set) are mounted sequentially around the outer periphery of the turntable 11 (on the frame, on the support plate, or outside the frame) and at the corresponding positions of the filter paper end cap tooling fixtures (above, below, or to the side). These mechanisms include a filter paper feeding tooling opening and closing mechanism 4, a first nonwoven fabric end cap feeding mechanism 5, a first welding mechanism 6, a tooling fixture flipping mechanism 7, a second nonwoven fabric end cap feeding mechanism 15, a second welding mechanism 16, and a finished end cap filter paper discharge mechanism 8. The turntable rotation mechanism 10, the filter paper feeding fixture opening and closing mechanism 4, the nonwoven fabric end cap first feeding mechanism 5, the first welding mechanism 6, the fixture flipping mechanism 7, the nonwoven fabric end cap second feeding mechanism 15, the second welding mechanism 16, and the end cap filter paper finished product discharge mechanism 8 are all electrically connected to the microcomputer control mechanism 9 and are uniformly controlled by it. The nonwoven fabric end cap second feeding mechanism 15 has the same structure as the nonwoven fabric end cap first feeding mechanism 5, and the second welding mechanism 16 has the same structure as the first welding mechanism 6. The center position of the turntable 11 does not rotate and is used for installation control.

[0023] Through the automatic intermittent rotation of the turntable rotation mechanism 10 and its turntable 11, the filter paper is fed, clamped, and positioned sequentially by the filter paper end cap tooling fixture 2 and tooling fixture positioning component 3, and the filter paper feeding tooling opening and closing mechanism 4. The non-woven fabric end cap first feeding mechanism 5 completes the feeding of the non-woven fabric end cap onto the filter paper (i.e., initial feeding). The first welding mechanism 6 completes the welding of the filter paper and the non-woven fabric end cap. The tooling fixture flipping mechanism 7 completes the flipping of the filter paper end cap tooling fixture and flattens the filter paper. The non-woven fabric end cap second feeding mechanism 15 completes the feeding of the non-woven fabric end cap onto the flipped filter paper (i.e., second feeding). The second welding mechanism 16 completes the second welding of the filter paper and the non-woven fabric end cap. The end cap filter paper finished product discharge mechanism 8 completes the finished product discharge. Thus, the entire process of welding the filter paper and the non-woven fabric end cap to form the filter element finished product is completed automatically.

[0024] like Figure 1 , Figure 2 As shown, the filter paper end cap tooling fixture 2 includes a flip bearing seat 20 mounted on the periphery of the turntable. The flip bearing seat 20 is connected to the tooling assembly frame 22 via a flip shaft 21. A feeding opening and closing assembly is installed inside the tooling assembly frame 22. One side of the tooling assembly frame 22 is movably connected to a tooling positioning shaft 23. The tooling positioning shaft 23 is mounted on the periphery of the turntable 11 via a positioning shaft mounting bracket 24. The tooling fixture positioning assembly 3 includes a tooling positioning fork 31 mounted above the tooling positioning shaft 23. The tooling positioning fork 31 is connected to a fork lateral movement force source 32 (a fork lateral movement cylinder). The fork lateral movement force source 32 is connected to a fork lifting power source 33 (a fork lifting cylinder). The fork lifting power source 33 is mounted on a support plate 13. The feeding opening and closing assembly includes a filter paper clamping moving block 26 (located on the outer side) installed in the tooling assembly frame. The tooling assembly frame has an inner groove 221 that mates with the filter paper clamping moving block 26 (which has a groove) (the two mate to form the shape of the filter paper for positioning). End cap positioning pieces 25 (two pieces in opposite positions, each with a groove that mates with the end cap and filter paper) are installed on both the inner groove 221 of the tooling assembly frame 22 and the filter paper clamping moving block 26. The filter paper clamping moving block 26 is connected to the outer side of the tooling assembly frame 22 via two moving block guide rods 27 (located on both sides) and a feeding opening and closing shaft 28 (located in the center). A compression spring 29 is installed on the moving block guide rods 27. The moving block guide rods 27 and the feeding opening and closing shaft 28 are arranged side-by-side. The space formed between the two end cap positioning pieces and between the inner groove 221 and the filter paper clamping moving block 26 is just enough to accommodate the upper and lower assembly of the non-woven end cap and the filter paper. The flip bearing seat 20, flip shaft 21, tooling assembly frame 22 (with inner groove 221), tooling positioning shaft 23, positioning shaft mounting bracket 24, and feeding opening and closing assembly (composed of filter paper clamping moving block 26, end cap positioning piece 25, moving block guide rod 27, feeding opening and closing shaft 28, and compression spring 29) constitute the filter paper end cap tooling fixture 2.

[0025] A flip-in-positioning sensor 34 is mounted on the tail of the flip shaft 20, and a positioning sensor 35 is mounted on the support plate 13 and on the side of the tooling fixture positioning assembly 3. The flip-in-positioning sensor 34 can rotate with the flip shaft 21 and the rotation of the turntable makes the flip-in-positioning sensor 34 correspond to the positioning sensor 35, thereby sensing the horizontality of the tooling assembly frame after flipping (it cannot be tilted, otherwise the tooling positioning shaft cannot be inserted into the tooling assembly frame). That is, whether the tooling fixture flipping mechanism has flipped the tooling assembly frame and the flip shaft into place, so as to prepare the tooling positioning fork of the tooling fixture positioning assembly 3 to re-insert the tooling positioning shaft into the tooling assembly frame. The feeding opening and closing assembly is installed in the tooling assembly frame 22, with one set on the left and one on the right. It corresponds to the feeding opening and closing of the filter paper feeding tooling opening and closing mechanism 4, the first end cap feeding of the nonwoven end cap first feeding mechanism 5, the first end cap filter paper welding of the first welding mechanism 6, the flat pressing and flipping of the tooling fixture flipping mechanism 7, the second end cap feeding of the nonwoven end cap second feeding mechanism 15, the second end cap filter paper welding of the second welding mechanism 16, and the finished product discharge of the end cap filter paper finished product discharge mechanism 8. There are also two sets of related process stations, thereby improving the assembly volume and work efficiency of end cap filter paper.

[0026] like Figure 1 , Figure 3 As shown, the filter paper feeding fixture opening and closing mechanism 4 includes a feeding lifting power source 41 (a feeding lifting cylinder, which is mounted on the frame 1) installed below the filter paper end cap fixture 2 (its fixture assembly frame 22). The feeding lifting power source 41 is connected to the feeding lifting opening and closing seat 42 (longitudinal position). The feeding lifting opening and closing seat 42 is respectively equipped with a filter paper support plate 43 (facing inward, corresponding to the position of the end cap positioning piece and the filter paper clamping moving block) and a feeding opening and closing power source 44 (facing outward, a feeding opening and closing cylinder). The feeding opening and closing power source 44 (through the opening and closing fork mounting plate 46) is connected to the feeding opening and closing fork 45 (lateral position). The feeding opening and closing fork 45 is located below the filter paper end cap fixture 2 (its feeding opening and closing shaft 28). The filter paper support plate 43 is mounted on the feeding lifting and opening seat 42 via a height adjustment guide rod 47. A height adjustment knob 48 is installed 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 can be adjusted by the height adjustment guide rod 47 to accommodate different specifications of filter paper.

[0027] First, the tooling positioning shaft 23 is positioned inside one side of the tooling assembly frame 22, positioning the tooling assembly frame in a horizontal position. The turntable 11 rotates the tooling assembly frame 22 to directly above 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 activated and rise through the opening and closing fork mounting plate 46, driving the feeding opening and closing fork 45 to pull the feeding opening and closing shaft 28 of the filter paper end cap tooling fixture 2 (along the moving block guide rod 27) outward, clamping the filter paper to the moving block 26 and the tooling assembly frame. The inner groove 221 and the two end cap positioning pieces are separated and opened, allowing filter paper to be manually placed longitudinally between the filter paper clamping moving 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 feeding opening and closing fork 45 is released, and the filter paper clamping moving block 26 and the inner groove 221, and the two end cap positioning pieces 25 are automatically pressed together and closed by the pressure spring 29 on the moving block guide rod 27, clamping the filter paper. Then, the turntable rotates the filter paper end cap tooling fixture 2 with filter paper to the position of the nonwoven fabric end cap first feeding mechanism 5.

[0028] like Figure 1 , Figure 4 , Figure 5 As shown, the first feeding mechanism 5 for nonwoven end caps includes a feeding frame 50. The feeding frame 50 is equipped with interconnected nonwoven end cap storage components 51 (including a storage turntable 512 mounted on the feeding frame 50, and several circumferentially arranged storage rods 511 mounted around the storage turntable, with stacked nonwoven end caps 14 fitted onto the storage rods 511), a nonwoven end cap lifting component 52 (including a linear lifting transmission module 522 mounted on the feeding frame 50, a lifting fork 521, and an end cap positioning sleeve 523, etc., where the lifting fork 521 is positioned on the bottommost nonwoven end cap and performs a linear lifting motion on it, allowing the lifted nonwoven end cap to be positioned within the end cap positioning sleeve 523), and a nonwoven end cap gripping and transferring component 53. The nonwoven end cap gripping and transferring component 53 (such as...) Figure 5(As shown) includes a transfer power source 531 (a transfer cylinder) mounted on a loading rack 50. The transfer power source 531 is connected to a gripping mounting plate 532 (in a lateral position). A gripping lifting power source 533 (a gripping lifting cylinder) is mounted on the gripping mounting plate 532. The gripping lifting power source 533 is connected to a gripping power source 534 (a gripping cylinder) (in a longitudinal position). The gripping power source 534 is connected to a gripping claw 535 (in a longitudinal position). The gripping claw 535 is a needle-shaped, extendable type. A stripping plate 536 is mounted around the gripping claw 535. The stripping plate 536 is connected to a stripping power source 538 (a stripping cylinder, which is mounted on the gripping lifting power source 533) via a stripping guide rod 537. The lifting fork 521 is connected to the linear lifting transmission module 522 (including a linear lifting power source and a lifting transmission assembly). The end cap positioning sleeve 523 is mounted on the feeding rack 50 and is located above the storage rod 511 and to the side of the transfer power source 531. The gripping claw 535 is located 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 together. 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 enter the end cap positioning sleeve 523 (multiple pieces at a time). Next, the gripping lifting power source 533 and gripping power source 534 of the nonwoven fabric end cap gripping and transferring assembly 53 are activated. The gripping claw 535, which has descended to its position, reaches the end cap positioning sleeve 523 and performs a needle-like opening at the center of the nonwoven fabric end cap to grip (one piece at a time) from its inner wall. It rises and is then carried by the transfer power source 531, along with the gripping mounting plate 532 and the nonwoven fabric end cap, to the filter paper end cap fixture 2. The gripping claw 535 descends and is activated by the unloading power source 538, which drives the unloading plate 536. At the same time, the gripping claw 535 releases and places the nonwoven fabric end cap on the filter paper already loaded in the filter paper end cap fixture. Then, the turntable rotates the filter paper end cap fixture 2 with the filter paper and nonwoven fabric end cap to the position of the first welding mechanism 6.

[0029] like Figure 1 , Figure 6As shown, the first welding mechanism 6 includes a welding frame 61 (mounted on a support plate). A transducer lifting and pressing power source 62 (a transducer lifting and pressing cylinder) is mounted on the top of the welding frame 61. A transducer 63 (with a transducer protective cover 60) and an ultrasonic welding head 64 (connected to each other and located above the material feeding and opening assembly) are connected below the transducer lifting and pressing power source 62. The ultrasonic welding head 64 is connected to a cold air blower 67 through a combination of a cold air cover 65 and a cold air pipe 66 connector. A filter element top plate 68 is mounted below the ultrasonic welding head 64. The filter element top plate 68 is connected to an upper lifting power source 69 (an upper lifting cylinder mounted on the frame 1). The filter paper end cap fixture 2, with filter paper and non-woven fabric end caps, rotates into position. The transducer lifting and pressing power source 62 is activated, lowering the transducer 63 and ultrasonic welding head 64 into position. Simultaneously, the lifting power source 69 is activated, causing the filter element top plate 68 to rise, pressing against the bottom of the filter paper. The transducer then operates, and the ultrasonic welding head welds the non-woven fabric end cap to the filter paper. Then, the turntable rotates the filter paper end cap fixture 2 (with filter paper and non-woven fabric end caps welded together) to the fixture flipping mechanism 7 position.

[0030] like Figure 1 , Figure 7As shown, the tooling fixture flipping mechanism 7 includes a flipping frame 71. A pressing and leveling power source 72 (a pressing and leveling cylinder) is mounted on the top outer end of the flipping frame 71. A leveling block 74 is connected to the pressing and leveling power source 72 via a leveling mounting plate 73. A tooling flipping power source 75 (a tooling flipping cylinder) is mounted in the middle of the flipping frame 71. This tooling flipping power source 75 is connected to a clamping power source 76 (a clamping cylinder). The clamping power source 76 is connected to clamping blocks 77 (two blocks, upper and lower, for opening or closing). The clamping blocks 77 correspond in position to the filter paper end cap tooling fixture 2 (its tooling assembly frame 22). A leveling pressing guide rod 78 is mounted on the leveling mounting plate 73 to smoothly press down and flatten the filter paper after flipping. The filter paper end cap fixture 2, which has filter paper and non-woven fabric end caps (welded together), rotates into place. The clamping power source 76 is activated, which drives the clamping block 77 to clamp the fixture assembly frame 22 of the filter paper end cap fixture 2. At the same time, the fork lifting power source 33 of the fixture positioning component 3 is activated, which lowers the fork lateral movement power source 32 and the fixture positioning fork 31 into place. Then, the fork lateral movement power source 32 is activated, which drives the fixture positioning fork 31 to pull the fixture positioning shaft 23 out of the fixture assembly frame 22. Subsequently, the fixture flipping power source 75 is activated, which flips the clamping power source 76, the clamping block 77, and the fixture assembly frame of the filter paper end cap fixture 2 180 degrees along the flipping shaft 21, flipping the bottom of the original filter paper to face upward. Then, the pressing and flattening power source 72 is activated, which uses the flattening block 74 to press and flatten the flipped filter paper. Then, the turntable rotates the filter paper end cap fixture 2, which contains the flipped and flattened filter paper and non-woven fabric end cap, sequentially to the positions of the second non-woven fabric end cap feeding mechanism 15 and the second welding mechanism 16 to perform the same second feeding and welding of the non-woven fabric end cap. Then, the turntable rotates the filter paper end cap fixture 2, which contains the filter paper and non-woven fabric end cap (secondary welding), to the end cap filter paper finished product discharge mechanism 8.

[0031] like Figure 1 , Figure 8 , Figure 9 , Figure 10 As shown, the end cap filter paper finished product discharge mechanism 8 includes a discharge rack 80, which is connected to a discharge lifting power source 81 (a discharge lifting cylinder). A discharge opening and closing power source 82 (a discharge opening and closing cylinder) is mounted on one side of the discharge rack 80. This discharge opening and closing power source 82 (via a discharge opening and closing fork mounting plate 86) is connected to a discharge opening and closing fork 83 (located above the discharge opening and closing assembly). A filter element ejection power source 84 (a filter element ejection cylinder) is mounted on the other side of the discharge rack 80. This filter element ejection power source 84 (via a filter element ejection mounting plate 87) is connected to a filter element ejection shaft 85. A finished product receiving assembly 89 is mounted below the filter element ejection shaft 85. Figure 9As shown, the finished product receiving assembly 89 includes a receiving frame 90 (mounted on the frame 1), and a receiving plate 91 (for receiving the finished filter element 88) is movably connected to the receiving frame 90. The receiving plate 91 is connected to a receiving lifting power source 92 (a receiving lifting cylinder, mounted on the frame). A pushing power source 93 (a pushing cylinder) is mounted on the side of the receiving frame 91. The pushing power source 93 is connected to a pushing plate 94, which is located on the side of the receiving plate 91. The filter paper end cap fixture 2, consisting of filter paper and non-woven fabric end caps (formed by secondary welding), rotates into position. The discharge lifting power source 81 is activated, causing the discharge rack 80, discharge opening and closing power source 82, and filter element ejection power source 84 to descend into position. The discharge opening and closing power source 82 then activates the discharge opening and closing fork 83, and the filter element ejection power source 84 activates the filter element ejection shaft 85. The discharge opening and closing fork 83 pulls the discharge opening and closing shaft 28 of the filter paper end cap fixture 2 outwards (along the moving block guide rod 27). Open, the filter paper clamping moving block 26 is separated from the inner groove 221 in the tooling assembly frame and the two end cap positioning pieces are opened, the filter element ejection shaft 85 ejects the filter element finished product 88 formed by the secondary welding of filter paper and non-woven fabric end cap, and the receiving plate 91 receives the material (the receiving lifting power source 92 starts and controls the rise to the position), and lowers it onto the receiving rack 90. ​​Then the pushing power source 93 starts and drives the pushing plate 94 to push the filter element finished product from the receiving rack and send it to the filter element finished product box on the outside of the frame.
