Description

Technical Field

[0001] This invention is an automated welding device for filter candles, belonging to the field of rapid automated welding of filter candle tubes and filter candle top seats. Background Technology

[0002] Currently, the welding process for filter candles mainly relies on manual loading and unloading. The welding equipment has a simple structure, and the welding parameters cannot be automatically adjusted according to voltage changes, resulting in unstable welding strength. The cylinder clamping of the filter tube and the top seat of the filter candle is not precise enough, and the unreasonable structure of the top seat clamping device causes the coaxiality and perpendicularity of the welding with the filter tube to fail to meet the product yield requirements, resulting in a lot of waste. In addition, the process cannot be automated, resulting in low production efficiency. Manual operation is dangerous and poses a great safety risk, which can easily lead to safety accidents. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automated welding equipment for filter candles.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] An automated filter tube welding device includes a filter tube feeding device, a top base feeding device, a clamping and positioning mechanism, and a resistance welding structure.

The bottoms of the vertical plates on both sides form discharge ports between the bottoms of the top seat clip hopper and the base clip hopper, respectively. A positioning block is provided at the top of the discharge port. The top of the base has two pushing cylinders that cooperate with the top seat clip hopper and the base clip hopper, respectively. The output end of the pushing cylinder extends into the discharge port. A second feeding servo electric cylinder is provided on the side of the base. A base is slidably connected to the second feeding servo electric cylinder. A second pneumatic gripper is provided on the base. The second pneumatic gripper is adapted to the discharge port.

[0009] Furthermore, the clamping and positioning mechanism includes a pneumatic chuck and a fixed base. The pneumatic chuck is equipped with an air inlet valve. Self-centering jaw one and self-centering jaw two are respectively provided on both sides of the pneumatic chuck. A guide rail is provided on the fixed base, and a movable base is slidably connected to the guide rail. A drag chain is connected to the side of the movable base. A centering adjustment component is provided on the outer surface of the movable base near the self-centering jaw two.

[0013] Furthermore, the conductive copper busbar on one side of the pneumatic self-centering gripper is the positive electrode, and the conductive copper busbar on one side of the self-centering gripper is the negative electrode.

[0014] Furthermore, both the pneumatic self-centering gripper and the second self-centering gripper are made of copper.

[0015] The beneficial effects of this invention are:

[0016] This invention enables rapid and automated welding of the filter tube and the filter top seat, allowing for automatic feeding, welding, and unloading, as well as automatic collection of semi-finished and finished products. It solves the problems of poor coaxiality between the filter tube and the top seat during welding, as well as the digitalization of welding parameters, thereby improving welding strength, automating welding, and increasing production efficiency.

[0017] This invention utilizes a filter tube feeding device. During use, several filter tubes are placed between the two hoppers. However, due to the large number of filter tubes, they can easily become disorganized and irregularly placed, making it difficult for them to align with the discharge outlet at the bottom of the grain hopper. In this situation, the electrical control box activates a lifting cylinder. The output of the lifting cylinder reciprocates, causing the vibrating plate to move back and forth, thus vibrating the filter tubes. This vibration helps to organize the filter tubes, ensuring they are neatly placed within the two hoppers. The filter tubes then fall to the sides of three sets of baffles, guided by the discharge outlet and the feeding rail.

[0018] This invention, through the design of the feeding mechanism, allows the filter tube to fall onto the two receiving plates. A feeding servo cylinder drives a pneumatic gripper to move and match the filter tube, securing it in place. Next, the receiving cylinder near the feeding servo cylinder is driven, causing the receiving plate to descend. At this point, the movement of the pneumatic gripper is unrestricted. The feeding servo cylinder is then activated, causing the pneumatic gripper and the filter tube to move horizontally, bringing the end of the filter tube to the clamping and positioning mechanism for secure clamping.

[0019] This invention utilizes a lifting cylinder and lifting plate design. When the filter tube falls to the side of the baffle, the lifting cylinder's output end extends and retracts, causing the lifting plate to move vertically. This, in turn, pushes the filter tube vertically upward via the lifting plate located at the bottom of the filter tube. The filter tube rises to the top height of the baffle. Without the baffle's resistance, the filter tube tilts and falls along the guide plate, eventually landing on the two receiving plates.

[0020] This invention utilizes a top seat and base feeding device design. A pusher cylinder is activated to push one of the top seat and base in the top seat and base clip hoppers, performing welding only one at a time. The top seat or base pushed by the pusher cylinder then moves to the positioning block. At this point, a pneumatic gripper two clamps the pushed top seat or base. Here, the pneumatic gripper two is pre-positioned at the positioning block. Next, a feeding servo cylinder two drives the clamped top seat or base to the clamping and positioning mechanism.

[0021] The present invention uses a clamping and positioning mechanism to clamp and fix the filter tube by self-centering jaw one and self-centering jaw two. The pneumatic self-centering jaw clamps and fixes the top seat or base sent by the top seat or base feeding device, thereby ensuring that the filter tube can be welded to the top seat or base.

[0022] This invention, through the design of the centering adjustment component, allows for the adjustment of the horizontal and vertical adjustment plates by rotating the vertical and horizontal adjustment screws when the axis of the pneumatic self-centering gripper is not aligned with the axis of the second self-centering gripper. This achieves the purpose of adjusting the axis of the pneumatic self-centering gripper.

[0023] This invention utilizes a resistance welding structure design. The pneumatic self-centering gripper moves forward again, causing the top seat or base to mate with the end of the filter tube located at the second position of the self-centering gripper. At the moment of contact, because the conductive copper bars on both sides are positive and negative copper bars respectively, and the grippers on both sides are also made of copper, current and voltage are released at the moment of contact, completing the welding action.

[0024] This invention, through the design of the unloading mechanism, ensures that after welding, all self-centering grippers (first, second, and pneumatic self-centering grippers) are reset and released, while pneumatic gripper first remains in the gripping state of the filter tube. Next, the feeding servo cylinder first is activated, moving the filter tube back to the side of the inclined fabric rack. Subsequently, the previously descending receiving cylinder moves the receiving plate back to the top, thus supporting the filter tube through the two receiving plates. Pneumatic gripper first then releases. Then, the two receiving cylinders descend synchronously, unloading the filter tube. When the receiving plate descends below the locking plate, the filter tube is held in place by the two locking plates and no longer moves with the receiving plate. The filter tube then descends along the inclined surface of the locking plate onto the unloading slide rail.

[0025] This invention achieves automatic feeding, welding, and unloading of materials by manually feeding the entire set of equipment, and automatically collects semi-finished and finished products. It is also equipped with corresponding audible and visual alarm devices, which will provide alarm prompts in case of equipment failure, production completion, or when manual intervention is required.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-11This invention provides a technical solution for automated filter tube welding equipment, including a filter tube feeding device, a top base feeding device, a clamping and positioning mechanism, and a resistance welding structure. The filter tube feeding device includes an inclined feed frame 1, with two symmetrically arranged hoppers 2 on the top inclined surface of the feed frame 1. Each hopper 2 has a discharge port 3 at its bottom that cooperates with the filter tube. A feeding slide rail 4 is located between the two hoppers 2 and at the top of the inclined feed frame 1. Both the feeding slide rail 4 and the discharge port 3 have baffles 5 at their lower ends. A guide plate 6 is located on the top of the baffles 5. A groove is formed on each of the two sides of the top of the inclined feed frame 1, and a lifting cylinder is installed within each groove. A vibrating plate 7 is connected to the top extension end of the lifting cylinder 1. A vibration plate 7 is provided on one side of the top of the inclined feed frame 1. The feeding mechanism cooperates with the guide plate 6, and the inclined fabric rack 1 is equipped with a feeding mechanism that cooperates with the feeding mechanism. Through the design of the filter tube feeding device, when in use, several filter tubes are placed between the two hoppers 2. At the same time, because the number of filter tubes is large, the filter tubes are prone to being placed messily and irregularly. This makes it impossible for the filter tubes to match the discharge port 3 at the bottom of the grain hopper 2. At this time, the lifting cylinder 1 is started by the electric control box. The output end of the lifting cylinder 1 reciprocates and extends, thereby driving the vibrating plate 7 to move back and forth, thereby vibrating several filter tubes. This allows the filter tubes to be combed while vibrating, so that the filter tubes can be neatly placed in the two hoppers 2. The filter tubes fall to the side of the three sets of baffles 5 through the guide of the discharge port 3 and the feeding slide rail 4.

[0041] See Figure 2 , Figure 4 The feeding mechanism includes a mounting plate 8 disposed on one side of the inclined fabric rack 1. An adjusting slide rail 9 is provided on the mounting plate 8, and a sliding seat 10 is slidably connected to the adjusting slide rail 9. A locking plate 11 is provided on the side of the sliding seat 10, and two locking seats 12 are symmetrically arranged on the top of the mounting plate 8. The locking plate 11 and the locking seats 12 are connected and fixed by a pin 13. A feeding servo cylinder 50 is connected to the top of the sliding seats 10 on both sides, and a pneumatic gripper 14 is slidably connected to the feeding servo cylinder 50. Through the design of the feeding mechanism… After the filter tube falls onto the two receiving plates 18, the pneumatic gripper 14 moves to match the filter tube via the feeding servo cylinder 50. The pneumatic gripper 14 clamps and fixes the filter tube. Then, the receiving cylinder 15 near the feeding servo cylinder 50 is driven. The receiving cylinder 15 at this position drives the receiving plate 18 to descend. At this time, the movement of the pneumatic gripper 14 is unrestricted. The feeding servo cylinder 50 is then started again. The feeding servo cylinder 50 drives the pneumatic gripper 14 and the filter tube to move horizontally, so that the end of the filter tube moves to the clamping and positioning mechanism for clamping and fixing.

[0042] See Figures 1-3The feeding mechanism includes two sets of receiving cylinders 15 and two sets of feeding baffles 16 disposed on the top side of the inclined fabric rack 1 and located between the mounting plate 8 and the guide plate 6, as well as lifting cylinders located on both sides of the feeding slide rail 4. The top output end of the lifting cylinder is connected to a lifting plate 17, and the top output end of the receiving cylinder 15 is provided with a receiving plate 18. Through the design of the lifting cylinder and the lifting plate 17, when the filter tube falls to the side of the baffle 5, the output end of the lifting cylinder extends and retracts to drive the lifting plate 18. The lifting plate 17 moves vertically, which in turn pushes the filter tube vertically upward through the lifting plate 17 located at the bottom of the filter tube. The filter tube will rise to the top height of the baffle 5. Without the baffle 5 to stop it, the filter tube will tilt and fall along the guide plate 6, and then fall onto the two receiving plates 18. A feeding slide rail 19 is connected below the feeding baffle 16. The bottom end of the feeding slide rail 19 is provided with a limiting plate 20. The sides of the two receiving plates 18 are respectively provided with proximity sensor 1 52 and proximity sensor 2 53. The sensor 52 is configured to detect whether the filter tube has descended onto the receiving plate 18. The proximity sensor 53 is configured to detect whether the filter tube moves with the feeding servo cylinder 50. Through the design of the unloading mechanism, after welding is completed, the self-centering grippers 30, 31, and 35 are all reset and released, while the pneumatic gripper 14 remains in the gripping state of the filter tube. Then, the feeding servo cylinder 50 is activated, causing the filter tube to reset and move to the inclined plane. On the side of the material rack 1, the receiving cylinder 15 that was originally descending then drives the receiving plate 18 to reset and rise, thereby supporting the filter tube through the two receiving plates 18. The pneumatic gripper 14 is then released. Then, the two receiving cylinders 15 descend synchronously, driving the filter tube to perform the unloading action. When the receiving plate 18 descends to below the locking plate 11, the filter tube will be held by the two locking plates 11 and will no longer move with the receiving plate 18. Subsequently, the filter tube will descend along the inclined surface of the locking plate 11 onto the unloading slide rail 19.

[0043] See Figures 5-7The top seat base feeding device includes a base 21. Two sets of mounting seats are symmetrically arranged on the top of the base 21. A top seat magazine 22 and a base magazine 23 are mounted on the sides of the mounting seats. Vertical plates are provided at the side openings of both the top seat magazine 22 and the base magazine 23. The bottoms of the vertical plates on both sides form discharge ports between the bottoms of the top seat magazine 22 and the base magazine 23, respectively. A positioning block 24 is provided at the top of the discharge port. Two pushing cylinders 25 are provided on the top of the base 21, respectively cooperating with the top seat magazine 22 and the base magazine 23. The output end of the pushing cylinder 25 extends into the discharge port. The sides of the base 21 are provided with… A second feeding servo cylinder 26 is provided, and a base is slidably connected to the second feeding servo cylinder 26. A second pneumatic gripper 27 is provided on the base, and the second pneumatic gripper 27 is adapted to the discharge port. Through the design of the top seat and base feeding device, the pusher cylinder 25 is activated to push one of the top seat and base in the top seat spring clip 22 and the base spring clip 23. Only one is pushed at a time for welding. Then, the top seat or base pushed by the pusher cylinder 25 will move to the positioning block 24. At this time, the pushed top seat or base is clamped by the second pneumatic gripper 27. Here, the second pneumatic gripper 27 is pre-moved to the positioning block 24. Then, the second feeding servo cylinder 26 drives the clamped top seat or base to move to the clamping and positioning mechanism.

[0044] See Figure 8 , Figure 9 , Figure 11 The clamping and positioning mechanism includes a pneumatic chuck 28 and a fixed base 32. The pneumatic chuck 28 is equipped with an air inlet valve 29. Self-centering jaw 1 30 and self-centering jaw 2 31 are respectively provided on both sides of the pneumatic chuck 28. A guide rail 33 is provided on the fixed base 32. A movable base 34 is slidably connected to the guide rail 33. A drag chain 51 is connected to the side of the movable base 34. A centering adjustment component is provided on the outer surface of the movable base 34 near the self-centering jaw 2 31. A pneumatic self-centering jaw 35 is connected to the centering adjustment component. The other side of the movable base 34 is connected to a servo cylinder 36. Through the design of the clamping and positioning mechanism, the filter tube is clamped and fixed by the self-centering jaw 1 30 and self-centering jaw 2 31. The pneumatic self-centering jaw 35 clamps and fixes the top seat or base sent by the top seat or base feeding device, thereby ensuring that the filter tube can be welded to the top seat or base.

[0045] See Figure 10The centering adjustment assembly includes a lateral adjustment plate 37 slidably connected laterally to the side of the movable base 34, a vertical adjustment plate 38 slidably connected vertically to the lateral adjustment plate 37, and the middle part of the vertical adjustment plate 38 connected to the pneumatic self-centering gripper 35. The movable base 34 has two screw-hole lugs 39 symmetrically arranged vertically, and a vertical adjustment screw 40 is threaded onto the screw-hole lugs 39. The end of the vertical adjustment screw 40 is pressed together with the vertical adjustment plate 38. The movable base 34 has two screw-hole lugs symmetrically arranged horizontally. There are two screw-hole lugs 41, and a transverse adjusting screw 42 is threaded onto each screw-hole lug 41. The end of the transverse adjusting screw 42 is pressed together with the transverse adjusting plate 37. Through the design of the centering adjustment component, when the axis of the pneumatic self-centering gripper 35 is not consistent with the axis of the self-centering gripper 31, the transverse adjusting plate 37 and the vertical adjusting plate 38 can be adjusted laterally and vertically by rotating the vertical adjusting screw 40 and the transverse adjusting screw 42, thereby achieving the purpose of adjusting the axis of the pneumatic self-centering gripper 35.

[0046] See Figure 8 , Figure 9 , Figure 11 The resistance welding structure includes a power distribution cabinet 43. Warning lights 44 and gas tanks 45 are respectively installed on the top two sides of the power distribution cabinet 43. A gas distribution box 46 is connected to the side of the power distribution cabinet 43. A conductive copper busbar 47 is connected to the output end of the power distribution cabinet 43. The conductive copper busbar 47 is connected to a conductive plate 48. The conductive plates 48 on both sides are connected to the self-centering gripper 31 and the pneumatic self-centering gripper 35 respectively via flexible copper busbars 49. The conductive copper busbar 47 on one side of the pneumatic self-centering gripper 35 is the positive electrode. The conductive copper busbar 47 on one side of the self-centering jaw 31 is the negative electrode. Both the pneumatic self-centering jaw 35 and the self-centering jaw 31 are made of copper, which facilitates current conduction to achieve the welding action. Through the design of the resistance welding structure, the pneumatic self-centering jaw 35 moves forward again to drive the top seat or base to match the end of the filter tube located at the self-centering jaw 31. At the moment of contact, because the conductive copper busbars 47 on both sides are positive and negative copper busbars respectively, and the jaws on both sides are also made of copper, current and voltage will be released at the moment of contact to complete the welding action.

[0047] During use, several filter tubes are placed between the two hoppers 2. Due to the large number of filter tubes, they may become disorganized and irregularly placed, making it difficult for them to align with the discharge outlet 3 at the bottom of the hopper 2. At this point, the lifting cylinder 1 is activated via the control box. The output end of the lifting cylinder 1 reciprocates, causing the vibrating plate 7 to move back and forth, thus vibrating the filter tubes. This vibration helps to organize the filter tubes, ensuring they are neatly placed within the hoppers 2. The filter tubes then fall to the sides of the three sets of baffles 5, guided by the discharge outlet 3 and the feeding slide rail 4. Simultaneously, the output end of the lifting cylinder extends and retracts, causing the lifting plate 17 to move vertically. The filter tube is then pushed vertically upward by the lifting plate 17 located at the bottom of the filter tube. The filter tube rises to the top height of the baffle 5. Without the baffle 5 to stop it, the filter tube tilts and falls down along the guide plate 6, landing on the two receiving plates 18. Then, the feeding servo cylinder 50 drives the pneumatic gripper 14 to move and match the filter tube, clamping and fixing it. Next, the receiving cylinder 15 near the feeding servo cylinder 50 is driven, causing the receiving plate 18 to descend. At this point, the movement of the pneumatic gripper 14 is unrestricted. The feeding servo cylinder 50 is then activated again, causing the pneumatic gripper 14 and the filter tube to move horizontally. The filter tube is moved so that its end moves into the clamping groove within the pneumatic chuck 28, extending to the self-centering jaw 31. The filter tube is clamped and fixed by the self-centering jaws 30 and 31. Next, the pusher cylinder 25 is activated to push one of the top seat or base in the top seat spring clip 22 and the base spring clip 23, pushing only one at a time for welding. The top seat or base pushed by the pusher cylinder 25 then moves to the positioning block 24. At this point, the pneumatic jaw 27 clamps the pushed top seat or base. Here, the pneumatic jaw 27 has been pre-moved to the positioning block 24. Then, the feeding servo cylinder 26 moves the clamped top seat or base to the pneumatic self-centering jaw 31. The pneumatic self-centering gripper 35 is moved laterally by the servo cylinder 36 to the axis of the gripper 35, so that the pneumatic self-centering gripper 35 docks with the top seat or base and clamps and fixes it. After clamping and fixing, the pneumatic self-centering gripper 35 is moved back one distance, so that the feeding servo cylinder 26 drives the pneumatic gripper 27 to reset and move. Then, the pneumatic self-centering gripper 35 moves forward again, so that the top seat or base matches the end of the filter tube located at the self-centering gripper 21. At the moment of contact, because the conductive copper busbars 47 on both sides are positive and negative copper busbars respectively, and the grippers on both sides are also made of copper, current and voltage will be released at the moment of contact, completing the welding action.After welding is completed, self-centering jaw 30, self-centering jaw 31, and pneumatic self-centering jaw 35 are all reset and released. Pneumatic jaw 14 remains in the clamping state with the filter tube. Then, the feeding servo cylinder 50 is activated, moving the filter tube back to the side of the inclined fabric rack 1. Subsequently, the receiving cylinder 15, which was originally descending, moves the receiving plate 18 back to the top, thus supporting the filter tube through the two receiving plates 18. Pneumatic jaw 14 is then released. Then, the two receiving cylinders 15 descend synchronously, moving the filter tube to unload. When the receiving plate 18 descends below the locking plate 11, the filter tube is held in place by the two locking plates 11 and no longer moves with the receiving plate 18. Subsequently, the filter tube descends along the inclined surface of the locking plate 11 onto the unloading slide rail 19. At this point, the operator only needs to remove the filter tube, rotate it 180 degrees, and put it back into the material bin 2 to repeat the above operation to complete the welding of the other end of the filter tube.

[0048] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

Pneumatic jaw 1 (14) is still clamped to the filter tube. Then, feeding servo cylinder 1 (50) is started, which drives the filter tube to reset and move to the side of the inclined fabric rack (1). Subsequently, the receiving cylinder (15) that was originally descending drives the receiving plate (18) to reset and rise, thereby supporting the filter tube through the two receiving plates (18). Pneumatic jaw 1 (14) is released. Then, the two receiving cylinders (15) descend synchronously, driving the filter tube to perform the unloading action. When the receiving plate (18) descends to below the locking plate (11), the filter tube will be abutted by the two locking plates (11) and will no longer move with the receiving plate (18). Subsequently, the filter tube will descend along the inclined surface of the locking plate (11) to the unloading slide rail (19).
