Description

Technical Field

[0001] The invention relates to the technical field of filter welding, and more specifically to a sealed filter screen port welding device based on automobile filter processing. Background Art

[0002] Automobile filter is a filter that filters impurities or gases. Among them, automobile air filter is the guardian of the engine. In the processing of automobile air filter, the connection between the filter port and the upper and lower shell end covers is an important link. Sealant is often used for connection. This connection method is prone to uneven glue coating and poor sealing.

[0003] After searching, the patent number CN104960194B discloses "A filter element welding machine". During the welding process, the filter paper tube is first put on the central mesh tube and installed on the filter paper tube fixture. At the same time, the two end covers are respectively fixed on two positioning mounting plates symmetrically arranged at the two horizontal and horizontal ends. After that, the longitudinal driving cylinder drives the crossbeam to slide horizontally and longitudinally to the heating station, and the heating device starts to work so that the end covers are evenly heated and the adhesive melts. After the heating is completed, the longitudinal driving cylinder drives the crossbeam to slide horizontally and longitudinally to the welding station. After that, the piston rods of the two horizontal driving cylinders located on both sides of the filter paper tube fixture extend out and act on the driven friction wheels at the corresponding ends respectively until the two end covers are respectively in contact with the two end surfaces of the filter paper tube on the filter paper tube fixture, and the two end covers are welded and fixed to the filter paper tube.

[0004] However, the patent adopts the method of melting the adhesive on the end cap in advance, and then moving the end cap with the melted adhesive to the two ends of the filter paper tube that have been positioned in advance. Before welding, each workpiece needs to be manually installed and positioned. The end cap is heated separately, and then the heated end cap is moved to the filter paper tube that has not been heated for direct butt welding. The whole operation process is not only cumbersome and difficult to realize automated production, but also it is not easy to ensure the welding quality by using adhesive bonding;

[0005] In addition, only the end annular ring of the filter paper tube is welded to the end cap. Therefore, when the end cap is heated by a heating device, the molten adhesive is more likely to drool during movement, resulting in uneven distribution of the adhesive on the end cap, affecting the subsequent welding quality.

[0006] Therefore, a sealed filter port welding device based on automobile filter processing is proposed to address the above-mentioned practical production and processing problems. Summary of the invention

[0011] Furthermore, the filter positioning tooling includes a positioning frame fixed on the welding table, a pair of bidirectional screws are rotatably installed between the upper end walls of the positioning frame, and the pair of bidirectional screws are installed with clamping blocks threadedly connected to them in the upper and lower directions. The pair of clamping blocks are used to clamp and position the filter cylinder.

[0012] Furthermore, the horizontal moving mechanism includes a pair of electric guide rails 1 embedded in the welding table, a supporting plate is installed on the pair of electric guide rails 1 for moving in the front and rear directions based on the electric guide rails 1, a pair of electric guide rails 2 are fixed on the supporting plate and are arranged vertically to the electric guide rails 1, and the pair of electric guide rails 2 are used to transport the moving seat horizontally in the left and right directions.

[0013] Furthermore, a loading chamber is provided inside the loading bin, which is connected to the interior of the stacking barrel and adapted to the end cover structure. The width of the loading chamber is consistent with the thickness of the end cover. The telescopic end of the push rod passes through the interior of the stacking barrel and is fixed with a mosaic plate that fits the outer end wall of the end cover.

[0014] Furthermore, a telescopic guide rod penetrating the interior of the stacking barrel is movably embedded in the end wall on the side away from the electric push cylinder in the upper and lower directions, and a tension spring is sleeved on the end of the telescopic guide rod located on the outside of the stacking barrel, and both ends of the tension spring are fixed between the outer end wall of the telescopic guide rod and the outer end wall of the stacking barrel.

[0015] Furthermore, the bracket is L-shaped, and a positioning block for clamping and installing the welding gun is fixed at the front end of the bracket. A pair of welding guns are symmetrically arranged about the axis of the positioning tube and the welding ends are inclined toward the adsorption end of the positioning tube.

[0016] Optionally, a welding layer extrusion structure is installed at opposite end walls of the upper and lower positioning blocks, and the welding layer extrusion structure includes an extrusion block located on the side of the welding gun fixed by a moving component.

[0017] Optionally, the moving assembly includes a horizontal push rod fixed on the bracket, a sliding block slidably mounted on the end wall of the positioning block is fixed to the telescopic end of the horizontal push rod, and a vertical push rod connected to the extrusion block at the telescopic end is fixed to the sliding block.

During welding, the filter cylinder only needs to be placed on the filter positioning fixture, and the filter cylinder is automatically clamped by the filter positioning fixture. The end cap loading fixture is used to push the stacked end caps to the adsorption end of the positioning cylinder for loading and positioning, and then the positioning cylinder is moved to the two ends of the filter cylinder by a horizontal moving mechanism. Finally, a pair of welding guns on the positioning cylinder are used to perform annular bidirectional hot-melt welding on the connection between the filter cylinder and the end cap along the circumferential direction. The entire process realizes automated loading, positioning, and welding, which is conducive to industrial production and ensures welding quality.

[0021] (2) This scheme also improves the welding process by adding an extrusion block at the welding gun through a moving assembly, and sleeves annular welding rods on both ends of the filter cylinder. During the welding process, firstly, a pair of upper and lower welding guns are used to perform preliminary heat melting on the connection between the filter cylinder and the end cover in a circular direction, and then the moving assembly is used to push the extrusion block outward, and the pair of extrusion blocks push the annular welding rod to the heat melting point between the filter cylinder and the end cover. Then, a pair of welding guns continue to move in a circular motion to heat melt the annular welding rod, so that the annular welding rod is tightly connected with the initially heat-melted connection between the filter cylinder and the end cover after heat melting. In this process, the synchronously rotating extrusion block is used to extrude the weld layer at the weld to form a regular weld layer, which effectively improves the welding quality between the filter positioning tooling and the filter cylinder.

DETAILED DESCRIPTION

[0038] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0039] Example 1: The present invention discloses a sealed filter port welding device based on automobile filter processing, please refer to Figure 1 , Figure 2 , including a filter positioning tool 2 fixedly installed at the middle of the upper end of the welding platform 1 and used to clamp and position the filter cylinder 3, the filter positioning tool 2 includes a positioning frame 21 fixed on the welding platform 1, a pair of bidirectional screws 22 are rotatably installed between the upper end walls of the positioning frame 21, and the pair of bidirectional screws 22 are installed with clamping blocks 23 threadedly connected thereto in the upper and lower directions, and the pair of clamping blocks 23 are used to clamp and position the filter cylinder 3;

[0040] A rotary motor for driving the bidirectional screw 22 to rotate synchronously is provided at the bottom of the positioning frame 21. Before welding, the filter cylinder 3 is directly placed on the clamping block 23 below, and the rotary motor is started. A pair of clamping blocks 23 move toward each other to realize bidirectional clamping of the filter cylinder 3.

[0041] See also Figure 1 , horizontal moving mechanisms are fixed on the left and right sides of the welding table 1, a moving seat 6 is installed on the horizontal moving mechanism, a positioning cylinder 7 for adsorbing and positioning the end cover 8 is fixedly embedded on the moving seat 6, and the axis of the positioning cylinder 7 is consistent with the center between a pair of clamping blocks 23, the horizontal moving mechanism includes a pair of electric guide rails 4 embedded and installed on the welding table 1, a pair of electric guide rails 4 are installed on the support plate based on the front and rear directions of the electric guide rails 4, a pair of electric guide rails 2 5 vertically arranged with the electric guide rails 4 are fixed on the support plate, and the pair of electric guide rails 2 5 are used to transport the positioning cylinder 7 on the moving seat 6 in the horizontal left and right directions.

[0042] See also Figure 3 The positioning cylinder 7 is located on the end wall of the inner side of the moving seat 6, and a rotating sleeve 9 is fixedly sleeved. The rotating sleeve 9 is fixedly installed with a welding gun 12 extending to the outer side of the adsorption end of the positioning cylinder 7 through a bracket 11 in the upper and lower directions. The bracket 11 is an L-shaped structure, and a positioning block 111 for clamping and installing the welding gun 12 is fixed at the front end of the bracket 11. A pair of welding guns 12 are symmetrically arranged about the axis of the positioning cylinder 7, and the welding ends are inclined toward the adsorption end of the positioning cylinder 7;

[0043] See also Figure 8 A driving motor 10 for rotating the positioning cylinder 7 is embedded on the movable seat 6, and the driving end of the driving motor 10 and the rotating sleeve 9 are embedded on the end wall of the movable seat 6 and are fixedly sleeved with gears that mesh with each other, so that the driving motor 10 drives the upper and lower welding guns 12 to rotate in the circumferential direction;

[0044] When a pair of end covers 8 are connected to both ends of the filter cylinder 3, a pair of welding guns 12 arranged on both sides are respectively placed in the upper and lower directions of the joint between the filter cylinder 3 and the end cover 8. During the rotation of the rotating sleeve 9, the pair of welding guns 12 perform annular bidirectional hot-melt welding on the joint between the filter cylinder 3 and the end cover 8, thereby shortening the welding path of a single welding gun 12.

[0045] Embodiment 2: Based on Embodiment 1, this embodiment adds a pair of end cap loading fixtures adapted to the positioning cylinder 7 and used for loading the end cap 8 on the welding table 1, so as to realize the automatic loading of the end cap 8 one by one without manual positioning and installation, as follows:

[0046] See also Figure 1 and Figure 4 The end cap loading tooling includes a stacking barrel 13 fixed on the welding table 1 and used for stacking a plurality of end caps 8 in the horizontal direction. A stacking opening is provided at the outer end of the stacking barrel 13, and an electric push cylinder 15 for pushing the end caps 8 inward is fixed at the stacking opening. A loading bin 14 connected to the end of the stacking barrel 13 away from the electric push cylinder 15 is fixed inside. A pushing rod 16 for pushing the end cap 8 located at the inner end of the stacking barrel 13 into the loading bin 14 is embedded and installed on the rear end wall of the stacking barrel 13;

[0047] See also Figure 4-Figure 7 A loading chamber is provided inside the loading bin 14, which is connected to the inside of the end side of the stacking barrel 13 and matched with the structure of the end cover 8. The width of the loading chamber is consistent with the thickness of the end cover 8. The telescopic end of the push rod 16 penetrates into the inside of the stacking barrel 13 and is fixed with a fitting plate 161 that fits the outer end wall of the end cover 8. In the initial state, the fitting plate 161 is embedded in the inner wall of the stacking barrel 13.

[0048] When the innermost end cover 8 abuts against the inner end wall of the stacking cylinder 13, the horizontal moving mechanism is used to move the positioning cylinder 7 until the adsorption end of the positioning cylinder 7 moves to the outer end of the loading chamber of the loading bin 14. At this time, the pushing rod 16 is started to push the interlocking plate 161 toward the loading bin 14. The interlocking plate 161 pushes the end cover 8 from the stacking cylinder 13 to the loading chamber of the loading bin 14 and contacts the adsorption end of the positioning cylinder 7. At this time, the electric moving rod installed in the positioning cylinder 7 is used to drive the moving piston 701 to the side away from the loading bin 14, so that the adsorption end of the positioning cylinder 7 is in a negative pressure state to adsorb and position the end cover 8, and then the horizontal moving mechanism is used to separate the end cover 8 from the loading bin 14 and move it to the outside of the end of the filter cylinder 3.

[0049] It should also be added that the end wall of the stacking barrel 13 away from the electric push cylinder 15 is movably embedded with a telescopic guide rod 131 penetrating therein in the upper and lower directions, and the end of the telescopic guide rod 131 located outside the stacking barrel 13 is sleeved with a tension spring, and the two ends of the tension spring are fixed between the outer end wall of the telescopic guide rod 131 and the outer end wall of the stacking barrel 13;

[0050] A pair of telescopic guide rods 131 are added, and the pair of telescopic guide rods 131 are arranged away from the interlocking plate 161, and are used to guide and limit the end cover 8 at the inner end. When the innermost end cover 8 is pushed out of the stacking tube 13, the pair of telescopic guide rods 131 are separated from the end cover 8 in the loading process, and extend inward under the action of the tension spring to continue to squeeze and limit the end cover 8 to be loaded, so as to prevent the end cover 8 to be loaded from tipping over due to the lack of a limiting structure after the innermost end cover 8 is pushed out of the stacking tube 13. When the pair of telescopic guide rods 131 limit the end cover 8 to be loaded, the interlocking plate 161 retreats to the inner wall of the stacking tube 13;

[0051] At this time, the electric push cylinder 15 is used to push the end cover 8 as a whole inward until the innermost end cover 8 is against the inner end wall of the stacking tube 13, and the telescopic guide rod 131 is squeezed to the inner wall of the telescopic guide rod 131. At this time, the pushing rod 16 is used to push the end cover 8 pushed to the innermost end of the stacking tube 13 to the upper silo 14 for loading. The end cover 8 located at the loading cavity of the loading silo 14 is consistent with the axis of the positioning tube 7 that moves and stays outside the loading silo 14, so as to facilitate the positioning tube 7 to directly contact and adsorb and position the outer end wall of the end cover 8. This cycle is repeated to achieve automatic positioning and loading of the end cover 8.

[0052] See also Figure 8 , Fig. 9 , and then use the horizontal moving mechanism to move the positioning cylinder 7 with the end cover 8 adsorbed and positioned to the end of the filter positioning tooling 2, and rely on the relative movement of the positioning cylinder 7 to correct the filter cylinder 3 until a pair of end covers 8 are respectively against the left and right ends of the filter cylinder 3, thereby simplifying the feeding and positioning process of the filter cylinder 3 and the end cover 8.

[0053] Finally, a pair of welding guns 12 on the positioning cylinder 7 are used to perform annular bidirectional hot-melt welding on the connection between the filter cylinder 3 and the end cover 8 along the circumferential direction. The entire process realizes automated loading, positioning, and welding, which is conducive to industrial production and ensures welding quality.

[0054] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment adds a welding layer extrusion structure matched with the welding gun 12, and pre-mounts an annular welding rod 301 on the end of the filter cylinder 3, and performs the process processing on the welding process, as follows:

[0055] See also Figure 9-13 , the upper and lower positioning blocks 111 are both provided with welding layer extrusion structures at opposite end walls, the welding layer extrusion structure includes an extrusion block 19 located on the side of the welding gun 12 fixed by a moving assembly, the moving assembly includes a horizontal push rod 17 fixed on the bracket 11, the telescopic end of the horizontal push rod 17 is fixed with a slider slidably installed on the end wall of the positioning block 111, and the slider is fixed with a vertical push rod 18 whose telescopic end is connected to the extrusion block 19;

[0056] The left and right ends of the filter cylinder 3 are movably sleeved with an annular welding rod 301, and a pair of extrusion blocks 19 arranged above and below extend to the inside of the annular welding rod 301. The annular welding rod 301 is in a quarter-circular ring structure. The bottom end wall of the extrusion block 19 away from the vertical push rod 18 is provided with an extrusion groove. The cross section of the extrusion groove is a wave-shaped structure with the middle protruding outward and the upper and lower sides extending outward.

[0057] During the welding process, firstly, a pair of upper and lower welding guns 12 are used to perform preliminary heat melting on the connection between the filter cylinder 3 and the end cover 8 in an annular direction, and then the moving assembly is used to push the extrusion block 19 outward, and the pair of extrusion blocks 19 push the annular welding rod 301 to the heat melting point between the filter cylinder 3 and the end cover 8. Then, the extrusion block 19 is separated from the annular welding rod 301 outward, and the pair of welding guns 12 continue to move in an annular manner to heat melt the annular welding rod 301, so that the annular welding rod 301 is closely connected with the connection between the filter cylinder 3 and the end cover 8 after heat melting, and the horizontal push rod 17 is located behind the rotation direction of the welding gun 12;

[0058] During this process, when the extrusion block 19 moves to the welding layer formed by the initial hot melting of the annular welding rod 301, the extrusion block 19 is moved outward again, and the welding layer at the weld is extruded by the synchronously rotating extrusion block 19. The extrusion groove with a wavy inner cross-section is beneficial for squeezing and rolling the flux at the weld to fully extend the weld and form a regular welding layer, thereby effectively improving the welding quality between the filter positioning tooling 2 and the filter cylinder 3.

[0059] When the welding work is completed, the clamping block 23 is retracted up and down, and the combined structure of the filter cylinder 3 and the end cover 8 is moved toward the side away from the end cover feeding tooling by using the horizontal moving mechanism, and a downwardly inclined material guide platform is added at the outer end 1. When the filter cylinder 3 moves to the material guide platform, the pair of welding guns 12 are turned over to prevent the welding guns 12 and the extrusion block 19 located below from cooperating and affecting the movement of the filter cylinder 3 to the top of the material guide platform. After the filter cylinder 3 is transported to the top of the material guide platform, the extrusion block 19 is retracted outward to release the negative pressure state of the positioning cylinder end cover 8, and the assembly structure of the filter cylinder 3 and the end cover 8 is separated from the pair of positioning cylinders 7 and transported out by the material guide platform;

[0060] When the next round of welding is carried out, each component returns to its initial position, and the operator places the next filter cylinder 3 to be processed on the clamping block 23 below. In this process, the filter cylinder 3 can be loaded and placed by a robot, and then the end cover loading tooling loads the end cover onto the positioning cylinder 7. The pair of positioning cylinders 7 are moved to the two ends of the filter cylinder 3 through the horizontal moving mechanism. After the positioning and docking are completed, the subsequent welding work is carried out.

[0061] In summary: during welding, the operator only needs to place the filter cylinder 3 on the filter positioning fixture 2, use the filter positioning fixture 2 to automatically clamp the filter cylinder 3, use the end cover feeding fixture to push the stacked end covers 8 to the adsorption end of the positioning cylinder 7 for feeding and positioning, and then use the horizontal moving mechanism to move the positioning cylinder 7 to the end of the filter positioning fixture 2, and rely on the relative movement of the positioning cylinder 7 to correct the filter cylinder 3 until a pair of end covers 8 are respectively against the left and right ends of the filter cylinder 3, and finally use a pair of welding guns 12 on the positioning cylinder 7 to perform annular bidirectional hot melting on the connection between the filter cylinder 3 and the end cover 8 along the circumferential direction;

[0062] The moving assembly is then used to push the extrusion block 19 outward, and a pair of extrusion blocks 19 push the annular welding rod 301 to the hot-melt position of the filter cylinder 3 and the end cover 8. Then, a pair of welding guns 12 continue to make circular motion to hot-melt the annular welding rod 301, so that the annular welding rod 301 is tightly connected with the initial hot-melt connection between the filter cylinder 3 and the end cover 8 after hot-melting. In this process, the synchronously rotating extrusion block 19 is used to extrude the weld layer at the weld to form a regular weld layer, which effectively improves the welding quality between the filter positioning tooling 2 and the filter cylinder 3. The entire process realizes automated loading, positioning, and welding, which is conducive to industrial production and ensures welding quality.

[0063] The above are only preferred specific implementation modes of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered within the protection scope of the present invention.
