Description

Technical Field

[0001] This invention belongs to the field of filter media keel welding technology, and particularly relates to a welding device for processing filter media keels. Background Technology

[0002] The automated welding machine tool for filter media keels of specific workpieces is an intelligent equipment designed for the efficient manufacturing of filter media keels, the core support component in industrial filtration equipment. As the skeleton structure of filtration equipment such as bag dust collectors, the design precision, material properties, and welding quality of the filter media keel directly determine the support stability, filtration efficiency, and overall lifespan of the equipment. Among them, the circular keel, as one of the most commonly used types, is made of longitudinal ribs and annular ribs welded together. The top is fixed to the filter bag by a venturi tube or clamp. It needs to withstand the impact of airflow, the gravity of dust, and the reverse force of pulse cleaning. Therefore, it has extremely high requirements for welding strength, structural symmetry, and surface flatness.

[0003] Existing technologies disclose several invention patents in the field of filter media keel welding technology. Among them, patent CN117359171B discloses a metal plate main keel welding equipment and welding method, including a frame. The frame includes a drive wheel and a driven wheel for conveying the main keel, and fixed frames located on both sides of the main keel. Welding execution components are elastically mounted on both the upper and lower sides of the fixed frames for welding U-shaped cold-formed thin-walled steel sections to the main keel. A drive component is used to intermittently push the U-shaped cold-formed thin-walled steel sections into contact with the main keel and move the welding execution components for welding. The component includes a transmission element connected to the driven wheel and an elliptical turntable located at the output end of the transmission element. A feeding plate, movably connected to the elliptical turntable and slidably connected to a fixed frame, pushes the welding execution component upwards. Through the cooperation of two sets of driving wheels, two sets of driven wheels, the drive component, and the feeding plate, automatic equidistant welding is achieved. The process is simple, eliminating the need for prior measurement and welding, thus improving work efficiency. Automatic feeding during welding is also possible, making it more convenient. However, this technical solution still has some shortcomings in its application. Existing welding processes have the following significant defects: First, the lack of effective positioning fixtures makes the keel components prone to shifting during the welding process, resulting in inaccurate weld point positions and poor product quality consistency. Secondly, to ensure connection strength, full welding is usually used. However, when working in a fixed position on the ground, only the upper surface of the keel can be welded. After the upper surface welding is completed, the entire keel must be flipped over before the lower surface welding can be carried out. This process not only reduces production efficiency but also increases the risk of errors caused by secondary positioning.

[0004] Based on this, the present invention designs a welding device for processing filter media keel to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the following significant defects in existing welding processes: First, the lack of effective positioning fixtures makes the keel components prone to displacement during welding, resulting in inaccurate weld point positions and poor product quality consistency. Second, to ensure connection strength, a full welding process is usually adopted, but when operating in a fixed ground state, only the upper surface of the keel can be welded. After completing the upper surface welding, the entire structure must be flipped over before the lower surface welding can be carried out. This process not only reduces production efficiency but also increases the risk of errors caused by secondary positioning.

It greatly reduces the time and cost of changing tooling and readjusting the machine, and is particularly suitable for flexible production of small batches and multiple varieties.

[0015] 2. In this invention, the unique design of combining the self-weight of the longitudinal ribs with the welding table surface enables automatic and rapid synchronous alignment of the bottom ends of multiple longitudinal ribs. This correction process does not require complex sensors or additional drive mechanisms. The structure is ingenious and highly reliable, fundamentally ensuring the verticality and bottom flatness of the keel assembly, laying a solid foundation for subsequent precise welding.

[0016] 3. In this invention, the clamping mechanism combines the advantages of elastic pre-tightening and rigid braking.

[0020] Please see the appendix Figure 1 - Appendix Figure 8 The present invention provides a technical solution: a welding device for processing filter media keel, comprising a welding table 1, wherein the welding table 1 is provided with: The transverse component 2 spans across the top of the welding table 1; At least one set of welding execution components 3 is mounted on the transverse component 2 and driven by the transverse component 2 to move laterally along the welding table 1; The loading robotic arm 4 is located on one side of the welding table 1; The positioning and clamping robotic arm 5 is located on the welding table 1 and works in conjunction with the loading robotic arm 4.

The output shaft of the first motor 2034 is connected to one end of the first threaded rod 2033. The welding execution assembly 3 includes a gantry frame 301 spanning the welding table 1. The two ends of the inner side of the gantry frame 301 are respectively connected to two first slide blocks 202. A second slide rail 302 is installed on its inner side. A second slide block 303 is slidably connected on the second slide rail 302. A bridging block 304 is connected to the outer side of the second slide block 303. A second threaded nut 305 is embedded at the end of the bridging block 304. The internal thread surface of the second threaded nut 305 is threaded with... The second lead screw 306 is driven at one end by the second motor 307 installed at the end of the gantry 301. The top of the bridging block 304 is equipped with a lifting component 308, which includes a third nut 3081 embedded in the bridging block 304 and a third lead screw 3085 threadedly engaged with the third nut 3081. The side of the bridging block 304 is equipped with a third slide block 3082, and the inner side of the third slide block 3082 is slidably connected to a third slide rail 3083. The outer side of the third slide block 3082 is fixed with a lifting seat 3084, and the top of the lifting seat 3084 is equipped with a third motor 3086 for driving the third lead screw 3085. A six-degree-of-freedom welding robot 309 is installed on the outer end face of the lifting seat 3084.

[0022] The specific implementation method is as follows: control the feeding robot arm 4 to send multiple ring ribs into the inner side of multiple longitudinal ribs, and finally feed the top cover and bottom cover. During this process, control the high degree of freedom welding robot 309 to perform welding, and control the first motor 2034, the second motor 307 and the third motor 3086 to work together to complete the welding process of the filter material keel.

[0023] Specifically, the adapter component 6 includes a compensation shaft 601 connected to the free end of the positioning and gripping robotic arm 5. The other end of the compensation shaft 601 is provided with a combination groove 602. An inner ring 603 is engaged in the groove of the combination groove 602. Multiple directional sleeves 604 arranged in a ring array are engaged on the ring surface of the inner ring 603. A directional shaft 605 is sleeved in each of the multiple directional sleeves 604. An umbrella-shaped shaft 606 is rotatably connected to the inner side of the end of the directional shaft 605. An outer ring 608 is embedded in the combination groove 602 corresponding to the outer periphery of the inner ring 603. Multiple adapter frames 607 arranged in a ring array are connected to the inner arc surface of the outer ring 608. The other ends of the multiple umbrella-shaped shafts 606 are rotatably connected to the inner side of the multiple adapter frames 607 respectively.

[0024] The specific implementation method is as follows: According to the filter media keel model, the fourth motor 9 is controlled to run. The output end of the fourth motor 9 drives the drive gear 8 to rotate through the gear shaft. The rotation of the drive gear 8 on the inner tooth surface 7 will drive the outer ring 608 to rotate inside the combination groove 602. Since the outer ring 608 will also drive multiple adapters 607 to perform circular motion synchronously during the rotation, the ends of multiple adapters 607 and multiple directional shafts 605 will move relative to each other. Multiple adapters 1005 will generate pushing or pulling force on multiple directional shafts 605 through multiple umbrella-shaped shafts 606, thereby changing the relative position between multiple clamping components 10. By adjusting the spacing between multiple longitudinal ribs, filter media keels with different inner diameters can be produced. According to the filter media keel model, select an appropriate amount of longitudinal ribs and ring ribs, as well as a top cover and a bottom cover. First, control the feeding robot arm 4 to insert multiple longitudinal ribs into the inner side of multiple sets of pre-clamping wheels 1102 in sequence, and the multiple longitudinal ribs are arranged in a ring array. Then, control the positioning and clamping robot arm 5 to drive multiple longitudinal ribs to move vertically downward with the welding table 1 as the horizontal plane. When the bottom end of the longitudinal rib contacts the top of the welding table 1 and can no longer move downward, since the longitudinal rib is rolled and connected to the two pre-clamping wheels 1102 of a set, the two pre-clamping wheels 1102 of a set will roll downward on the corresponding longitudinal rib until the bottom end of multiple longitudinal ribs contacts the top of the welding table 1 and the ends of multiple longitudinal ribs are aligned, thereby quickly completing the correction of the arrangement of multiple longitudinal ribs.

[0025] Specifically, the inner bottom of the combination groove 602 is provided with an adapter hole 12, and a gear shaft is rotatably connected in the adapter hole 12. A drive gear 8 is fitted at the end of the gear shaft. The inner ring 603 of the outer ring 608 is provided with an internal tooth surface 7. The outer ring 608 meshes with the drive gear 8 through the internal tooth surface 7. A fourth motor 9 is installed at the bottom of the compensation shaft 601. The output end of the fourth motor 9 is connected to the other end of the gear shaft. The clamping assembly 10 includes a connector 1001 connected to the other end of the directional shaft 605. The other end of the connector 1001 is connected to a fourth slide rail 1002. Two second slide blocks 303 are slidably connected on the fourth slide rail 1002. The top of each of the two second slide blocks 303 is connected to an adapter 1005. The other end of each of the two adapters 1005 is rotatably connected to an arc-shaped connecting plate 1006. An inner side of the connector 1001 is installed with... The fifth motor 1008 has a torsion bar 1007 mounted on its output end. The two ends of the torsion bar 1007 are rotatably connected to the ends of the two arc-shaped connecting plates. The other side of each of the two second slide blocks 303 is connected to a chuck 1004. A pre-clamping assembly 11 is snapped into the inner side of the chuck 1004. The pre-clamping assembly 11 includes an inner liner box 1101 snapped into the inner side of the chuck 1004. A pre-clamping wheel 1102 is embedded in the inner side of the inner liner box 1101. Multiple support holes are opened on the end face of the pre-clamping wheel 1102. A support shaft 1103 is sleeved in each of the multiple support holes. The end of the support shaft 1103 is connected to the inner wall of the inner liner box 1101. A support spring 1104 is sleeved on the support shaft 1103. The pre-clamping wheel 1102 is elastically supported and connected to the inner wall of the inner liner box 1101 through multiple support springs 1104. The end face of the pre-clamping wheel 1102 is provided with a brake hole, and a brake shaft 1105 is sleeved in the brake hole. The end of the brake shaft 1105 is connected to the inner wall of the inner liner box 1101.

[0026] The specific implementation method is as follows: After the arrangement and alignment of multiple longitudinal ribs, the fifth motor 1008 is controlled to run. The fifth motor 1008 drives the torsion bar 1007 to rotate. The two ends of the torsion bar 1007 simultaneously apply lateral tension to the two connectors 1001 through two arc-shaped connecting plates 1006. The two connectors 1001 drive the two second slide blocks 303 to slide on the fourth slide rail 1002, thereby driving the two clamps 1004 to move closer to each other. During the process of the two clamps 1004 moving closer to each other, the force between the pre-clamping wheel 1102 and the longitudinal ribs gradually increases. The pre-clamping wheel 1102 is connected to multiple support shafts 110 through multiple support holes. 3. The roller slides upward and compresses the support spring 1104 to cause it to deform elastically. During this process, the pre-clamping wheel 1102 also slides on the brake shaft 1105 through the brake hole. The anti-slip end of the brake shaft 1105 contacts the wheel surface of the pre-clamping wheel 1102. By using the support of the brake shaft 1105 and the anti-slip surface, the pre-clamping wheel 1102 is prevented from rotating, thereby ensuring the stability of the longitudinal rib. This not only improves the connection strength but also improves the welding efficiency. At the same time, the roller moves through the feeding robot arm 4, eliminating the need for manual position adjustment, making it more convenient to use. Furthermore, the moving and positioning distance can be adjusted, facilitating the positioning of keels with different spacings.

[0027] Working principle and usage: Flexible clamping and diameter adjustment: Based on the model of the target filter media keel, the fourth motor 9 is started. The output end of the fourth motor 9 drives the drive gear 8, which meshes with it, to rotate through the gear shaft. Since the drive gear 8 is fixed on the inner tooth surface 7 of the combination groove 602, its rotation will drive the outer ring 608 to rotate within the combination groove 602. The outer ring 608 pushes each umbrella shaft 606 to move through the adapter frame 607 of its inner annular array. The umbrella shaft 606 converts the circumferential motion into an axial thrust or pull on the directional shaft 605, thereby driving each clamping component 10 to move synchronously in the radial direction. Through this linkage mechanism, the annular distribution diameter between multiple longitudinal ribs can be precisely adjusted to adapt to the production needs of filter media keels with different inner diameter specifications. For longitudinal rib feeding and automatic alignment, after selecting a specified number of longitudinal ribs, ring ribs, top cover, and bottom cover, follow these steps: control the feeding robot arm 4 to feed multiple longitudinal ribs sequentially into the corresponding pre-clamping wheel 1102 group, so that they are arranged in a ring array; control the positioning and clamping robot arm 5 to drive the entire set of longitudinal ribs vertically downward along the welding table 1; when the bottom end of the longitudinal rib is blocked from contacting the surface of the welding table 1, since the pre-clamping wheel 1102 is in rolling connection with the longitudinal rib, the clamping wheel will roll down along the surface of the longitudinal rib until the bottom end of all longitudinal ribs is in contact with the table surface, thereby achieving end-face alignment and completing rapid correction. After clamping, locking, and feeding of the ring ribs, and aligning the longitudinal ribs, the clamping procedure is executed. The fifth motor 1008 is started, driving the torsion bar 1007 to rotate. The arc-shaped connecting plates 1006 at both ends of the torsion bar 1007 simultaneously pull the two connecting heads 1001, causing the second slide block 303 to slide towards each other along the fourth slide rail 1002, so that the two sets of clamps 1004 move closer together. As the clamps 1004 close, the pressure of the pre-clamping wheel 1102 on the longitudinal ribs gradually increases, and the support spring 1104 is deformed under pressure to provide continuous clamping force. At the same time, the pre-clamping wheel 1102 slides along the brake shaft 1105 until its anti-slip end is in close contact with the wheel surface, forming a brake. This structure effectively suppresses the displacement of the longitudinal ribs, and significantly improves the work efficiency while ensuring the connection strength and welding accuracy. After welding and forming, and completing the positioning and clamping of the longitudinal ribs, the loading robotic arm 4 is controlled to send the ring ribs one by one into the inner side of the longitudinal rib ring. Then, the top cover and bottom cover are loaded in sequence. The high-degree-of-freedom welding robot 309 is started, and the first motor 2034 is moved horizontally, the second motor 307 is moved horizontally and vertically, and the third motor 3086 is lifted and lowered in linkage to realize the automated welding of the intersection of the longitudinal rib and the ring rib, and finally complete the overall forming process of the filter material keel.
