[0002] Currently, during the welding process of filter candles, mainly manual loading and unloading are carried out. The welding device has a simple structure, and the welding parameters cannot be automatically adjusted according to voltage changes, resulting in unstable welding strength.

The structure of the clamping device for the filter candle top seat is unreasonable, resulting in the coaxiality and perpendicularity of the welding with the filter tube not meeting the product yield requirements, causing a large amount of waste. In addition, the process cannot achieve automatic production, with low production efficiency, and manual operation is very dangerous with a high safety risk, easily causing safety accidents.

[0013] Further, both the pneumatic self-centering jaw and the self-centering jaw II are made of copper materials.

[0014] Advantages of the present invention: The present invention realizes the rapid automatic welding action of the filter candle filter tube and the filter candle top seat, can realize automatic feeding, welding, and unloading, and automatically collect semi-finished products and finished products, solves the problem of poor coaxiality in the welding of the filter tube and the top seat during the welding process and the digitization of welding parameters, improves the welding strength, realizes welding automation, and improves production efficiency.

[0015] Through the design of the filter tube feeding device of the present invention, during use, several filter tubes are placed between the two side bins. At the same time, because the number of filter tubes placed is large, it is easy to have the situation of messy and irregular placement of the filter tubes. In this way, the filter tubes cannot match the discharge bin openings at the bottom of the granary. At this time, the lifting cylinder I is started through the electric control box. The output end of the lifting cylinder I reciprocates to drive the tremor plate to move reciprocally, and then tremor several filter tubes, so that the filter tubes can be sorted while trembling, and the filter tubes can be neatly placed in the two side bins. The filter tubes fall to the side of the three groups of baffles under the guidance of the discharge bin openings and the feeding slide rails.

[0016] Through the design of the feeding mechanism of the present invention, when the filter tubes fall on the two receiving plates, the pneumatic jaw I is driven by the feeding servo electric cylinder I to move to match the filter tubes, and the pneumatic jaw I clamps and fixes the filter tubes. Then, the receiving cylinder near the feeding servo electric cylinder I is driven. The receiving cylinder at this position drives the receiving plate to descend. At this time, the movement of the pneumatic jaw I is no longer restricted. Then, the feeding servo electric cylinder I is started, and the feeding servo electric cylinder I drives the pneumatic jaw I and the filter tubes to move horizontally, so that the end of the filter tube moves to the clamping and positioning mechanism for clamping and fixing.

[0017] Through the design of the lifting cylinder and the lifting plate, after the filter tube drops to the side of the baffle, the telescopic movement of the output end of the lifting cylinder drives the lifting plate to move vertically, and then the filter tube is pushed vertically upward by the lifting plate located at the bottom of the filter tube. The filter tube will rise to the top height of the baffle. Without the abutting and limiting of the baffle, the filter tube will tilt and fall along the guide plate, and then fall on the two receiving plates.

[0018] Through the design of the top seat base feeding device, the pushing cylinder is started to push one of the top seats and bases in the top seat magazine and the base magazine. Only one is pushed at a time for the welding action. Subsequently, the pushed top seat or base will move to the positioning block. At this time, the pushed top seat or base is clamped by the pneumatic gripper II. Here, the pneumatic gripper II is pre-moved to the positioning block. Then, the feeding servo cylinder II drives the clamped top seat or base to move to the clamping and positioning mechanism.

[0019] Through the design of the clamping and positioning mechanism, the filter tube is clamped and fixed by the self-centering gripper I and the self-centering gripper II. The pneumatic self-centering gripper clamps and fixes the top seat or base sent by the top seat base feeding device, so as to ensure that the filter tube can be welded to the top seat or base.

[0020] Through the design of the centering adjustment component, when the axis of the pneumatic self-centering gripper is not aligned with the axis of the self-centering gripper II, at this time, the horizontal and vertical adjustment of the horizontal adjustment plate and the vertical adjustment plate is realized by rotating the vertical adjustment screw and the horizontal adjustment screw, so as to achieve the purpose of adjusting the axis of the pneumatic self-centering gripper.

[0021] Through the design of the resistance welding structure, the pneumatic self-centering gripper advances again to drive the top seat or base to fit with the end of the filter tube at the self-centering gripper II. At the moment of contact, because the conductive copper bars on both sides are the positive and negative copper bars respectively, and at the same time, the grippers on both sides are also made of copper, so at the moment of contact, current and voltage will be released to complete the welding action.

[0022] Through the design of the blanking mechanism, after the welding is completed, the self-centering gripper I, the self-centering gripper II, and the pneumatic self-centering gripper all reset and loosen. The pneumatic gripper I is still in the clamping state with the filter tube. Then, the feeding servo cylinder I is started to drive the filter tube to reset and move to the side of the inclined material rack. Subsequently, the originally lowered receiving cylinder drives the receiving plate to reset and rise, and then the filter tube is supported by the two receiving plates. The pneumatic gripper I then loosens. Then, the two receiving cylinders synchronously descend to drive the filter tube to realize the blanking action. When the receiving plate descends to below the locking plate, the filter tube will be abutted by the two locking plates and will no longer move with the receiving plate. Subsequently, the filter tube will descend along the inclined surface of the locking plate to the blanking slide rail.

[0023] The present invention realizes automatic feeding, welding, and discharging through a complete set of equipment with manual feeding (raw materials), and automatically collects semi-finished products and finished products. A corresponding sound and light alarm device is provided, and in the case of equipment failure, production end, or the need for manual intervention, the equipment gives an alarm prompt.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 11, the present invention provides a technical solution for an automatic welding device for filter candles, including a filter tube workpiece feeding device, a top seat base feeding device, a clamping and positioning mechanism, and a resistance welding structure. The filter tube feeding device includes an inclined material rack 1, and two material bins 2 are symmetrically arranged on the top inclined surface of the inclined material rack 1. The bottom of the material bin 2 is provided with a discharge bin opening 3 that matches the filter tube. Between the two material bins 2 and on the top of the inclined material rack 1, there is a feeding slide rail 4. At the lower ends of the feeding slide rail 4 and the discharge bin opening 3, there are baffles 5. On the top of the baffle 5, there is a guide plate 6. On both sides of the top of the inclined material rack 1, there is a groove respectively. An elevating cylinder 1 is arranged in the groove. The top telescopic end of the elevating cylinder 1 is connected with a vibrating plate 7. On one side of the top of the inclined material rack 1, there is a feeding mechanism that matches the guide plate 6. Inside the inclined material rack 1, there is a feeding mechanism that matches the feeding mechanism; through the design of the filter tube feeding device, during use, several filter tubes are placed between the two side material bins 2. At the same time, because the number of filter tubes placed is large, it is easy to have the situation of messy and irregular placement of filter tubes. In this way, the filter tubes cannot match the discharge bin opening 3 at the bottom of the material bin 2. At this time, the elevating cylinder 1 is started through the electric control box. The output end of the elevating cylinder 1 reciprocates telescopically to drive the vibrating plate 7 to move reciprocally, and then vibrates several filter tubes, so that the filter tubes can be sorted while vibrating, and the filter tubes can be neatly placed in the two side material bins 2. The filter tubes fall to the side of the three baffles 5 under the guidance of the discharge bin opening 3 and the feeding slide rail 4.

[0029] Refer to Figure 2 , Figure 4 , the feeding mechanism includes a mounting plate 8 arranged on one side of the inclined material rack 1. An adjusting slide rail 9 is arranged on the mounting plate 8. A sliding seat 10 is slidably connected to the adjusting slide rail 9. A locking plate 11 is arranged on the side of the sliding seat 10. Two locking seats 12 are symmetrically arranged on the top of the mounting plate 8. The locking plate 11 and the locking seat 12 are connected and fixed through a pin 13. The tops of the two sliding seats 10 on both sides are connected with a feeding servo cylinder 1 50. A pneumatic gripper 1 14 is slidably connected to the feeding servo cylinder 1 50; through the design of the feeding mechanism, when the filter tubes fall on the two receiving plates 18, the feeding servo cylinder 1 50 drives the pneumatic gripper 1 14 to move to match the filter tubes, and the pneumatic gripper 1 14 clamps and fixes the filter tubes. Then, the receiving cylinder 15 close to the feeding servo cylinder 1 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 1 14 is no longer restricted. Then, the feeding servo cylinder 1 50 is started, and the feeding servo cylinder 1 50 drives the pneumatic gripper 1 14 and the filter tubes to move horizontally, so that the end of the filter tube moves to the clamping and positioning mechanism for clamping and fixing.

[0030] Refer to Figures 1 - 3, the blanking mechanism includes two groups of receiving cylinders 15 and two groups of blanking baffles 16 arranged at the top side of the inclined material rack 1 and located between the mounting plate 8 and the guide plate 6, and lifting cylinders located on both sides of the loading slide rail 4. The top output end of the lifting cylinder is connected with 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 telescopic movement of the output end of the lifting cylinder drives the lifting plate 17 to move vertically, and then the filter tube is pushed vertically upward by the lifting plate 17 located at the bottom of the filter tube. The filter tube will rise to the height of the top of the baffle 5. Without the abutting and limiting of the baffle 5, the filter tube will fall obliquely along the guide plate 6 and then fall on the two receiving plates 18; a blanking slide rail 19 is connected below the blanking baffle 16, and a limiting plate 20 is arranged at the bottom end of the blanking slide rail 19; proximity sensors 52 and 53 are respectively arranged on the sides of the two receiving plates 18; through the setting of the proximity sensor 52, it can be detected whether the filter tube has dropped onto the receiving plate 18, and through the setting of the proximity sensor 53, it can be detected whether the filter tube moves along with the feeding servo cylinder 50; through the design of the blanking mechanism, after the welding is completed, the self-centering jaw 30, the self-centering jaw 31, and the pneumatic self-centering jaw 35 all reset and loosen, and the pneumatic jaw 14 is still in the clamping state with the filter tube. Then, the feeding servo cylinder 50 is started to drive the filter tube to reset and move to the side of the inclined material rack 1. Subsequently, the originally lowered receiving cylinder 15 drives the receiving plate 18 to reset and rise, and then the filter tube is supported by the two receiving plates 18. The pneumatic jaw 14 then loosens. Then, the two receiving cylinders 15 synchronously descend to drive the filter tube to achieve the blanking action. When the receiving plate 18 descends below the locking plate 11, the filter tube will be abutted by the two locking plates 11 and will no longer move along with the receiving plate 18. Subsequently, the filter tube will descend along the inclined surface of the locking plate 11 onto the blanking slide rail 19.

[0031] Refer to Figures 5 - 7, the top base feeding device includes a base 21, two groups of mounting seats are symmetrically arranged on the top of the base 21, a top seat magazine 22 and a base magazine 23 are installed on the side of the mounting seat, vertical plates are provided at the side openings of both the top seat magazine 22 and the base magazine 23, and discharge ports are formed between the bottoms of the vertical plates on both sides and 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 respectively cooperating with the top seat magazine 22 and the base magazine 23 are arranged on the top of the base 21. The output end of the pushing cylinder 25 penetrates into the discharge port. A feeding servo cylinder two 26 is arranged on the side of the base 21. A base is slidably connected to the feeding servo cylinder two 26. A pneumatic gripper two 27 is arranged on the base. The pneumatic gripper two 27 is adapted to the discharge port; through the design of the top base feeding device, the pushing cylinder 25 is started to push one of the top seats and bases in the top seat magazine 22 and the base magazine 23, and only one is pushed at a time for the welding operation. Subsequently, the pushed top seat or base will move to the positioning block 24. At this time, the pushed top seat or base is clamped by the pneumatic gripper two 27. Here, the pneumatic gripper two 27 is pre-moved to the positioning block 24. Then, the feeding servo cylinder two 26 drives the clamped top seat or base to move to the clamping and positioning mechanism.

[0032] Refer to Figure 8 , Figure 9 , Figure 11 , the clamping and positioning mechanism includes a pneumatic chuck 28 and a fixed seat 32. An air inlet valve 29 is provided on the pneumatic chuck 28. A self-centering gripper one 30 and a self-centering gripper two 31 are respectively arranged on both sides of the pneumatic chuck 28. A guide rail 33 is arranged on the fixed seat 32. A moving seat 34 is slidably connected to the guide rail 33. A drag chain 51 is connected to the side of the moving seat 34. A centering adjustment component is arranged on the outer surface of the moving seat 34 near the side of the self-centering gripper two 31.

The other side of the moving seat 34 is connected to a servo cylinder three 36; through the design of the clamping and positioning mechanism, the filter tube is clamped and fixed by the self-centering gripper one 30 and the self-centering gripper two 31, and the pneumatic self-centering gripper 35 clamps and fixes the top seat or base sent by the top base feeding device, so as to ensure that the filter tube can be welded to the top seat or base.

[0033] Refer to Figure 10, the centering adjustment assembly includes a lateral adjustment plate 37 that is laterally slidably connected to the side of the moving seat 34. A vertical adjustment plate 38 is vertically slidably connected to the lateral adjustment plate 37. The middle of the vertical adjustment plate 38 is connected to the pneumatic self-centering chuck 35. Two screw hole ear plates one 39 are symmetrically arranged vertically on the moving seat 34. A vertical adjustment screw 40 is threadedly connected to the screw hole ear plate one 39. The end of the vertical adjustment screw 40 is pressed against the vertical adjustment plate 38. Two screw hole ear plates two 41 are symmetrically arranged horizontally on the moving seat 34. A lateral adjustment screw 42 is threadedly connected to the screw hole ear plate two 41. The end of the lateral adjustment screw 42 is pressed against the lateral adjustment plate 37. Through the design of the centering adjustment assembly, when the axis of the pneumatic self-centering chuck 35 is not aligned with the axis of the self-centering chuck two 31, at this time, by rotating the vertical adjustment screw 40 and the lateral adjustment screw 42, the lateral and vertical movement of the lateral adjustment plate 37 and the vertical adjustment plate 38 can be realized, so as to achieve the purpose of adjusting the axis of the pneumatic self-centering chuck 35.

[0034] Refer to Figure 8 , Figure 9 , Figure 11 , the resistance welding structure includes a power distribution cabinet 43. Warning lights 44 and air storage tanks 45 are respectively arranged on both sides of the top of the power distribution cabinet 43. An air circuit distribution box 46 is connected to the side of the power distribution cabinet 43. One conductive copper bar 47 is respectively connected to the output end of the power distribution cabinet 43. The conductive copper bar 47 is connected to the conductive disc 48. The two conductive discs 48 on both sides are respectively connected to the self-centering chuck two 31 and the pneumatic self-centering chuck 35 through flexible copper bar connections 49. The conductive copper bar 47 on one side of the pneumatic self-centering chuck 35 is the positive pole, and the conductive copper bar 47 on one side of the self-centering chuck two 31 is the negative pole. Both the pneumatic self-centering chuck 35 and the self-centering chuck two 31 are made of copper materials, so as to facilitate current conduction to achieve the welding action. Through the design of the resistance welding structure, the pneumatic self-centering chuck 35 advances again to drive the top seat or the base to be adapted to the end of the filter pipe at the self-centering chuck two 31. At the moment of contact, because the two conductive copper bars 47 on both sides are positive and negative copper bars respectively, and at the same time, the two chucks on both sides are also made of copper, so at the moment of contact, current and voltage will be released to complete the welding action.

[0035] During use, several filter tubes are placed between the silos 2 on both sides. At the same time, because the number of filter tubes placed is large, it is easy to have a situation where the filter tubes are messy and irregularly placed. In this way, the filter tubes cannot match the discharge openings 3 at the bottom of the silos 2. At this time, the lifting cylinder 1 is started through the electric control box. The output end of the lifting cylinder 1 reciprocates to drive the vibration plate 7 to move reciprocally, thereby vibrating several filter tubes, so that the filter tubes can be sorted while vibrating, and the filter tubes can be neatly placed in the silos 2 on both sides. The filter tubes fall to the side of the three groups of baffles 5 under the guidance of the discharge opening 3 and the feeding slide rail 4. At this time, the output end of the lifting cylinder extends and retracts to drive the lifting plate 17 to move vertically, and then the filter tubes are pushed vertically upward by the lifting plate 17 located at the bottom of the filter tubes. The filter tubes will rise to the height of the top of the baffle 5. Without the abutting and limiting of the baffle 5, the filter tubes will fall obliquely along the guide plate 6 and then fall on the two receiving plates 18. Subsequently, the feeding servo cylinder 1 50 drives the pneumatic gripper 1 14 to move to match the filter tubes. The pneumatic gripper 1 14 clamps and fixes the filter tubes. Then, the receiving cylinder 15 near the feeding servo cylinder 1 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 1 14 is no longer restricted. Then, the feeding servo cylinder 1 50 is started. The feeding servo cylinder 1 50 drives the pneumatic gripper 1 14 and the filter tubes to move horizontally, so that the end of the filter tube moves into the clamping groove in the pneumatic chuck 28, and the end extends to the self-centering gripper 2 31. The filter tube is clamped and fixed by the self-centering gripper 1 30 and the self-centering gripper 2 31. Then, the pushing cylinder 25 is started to push one of the top seat and the base in the top seat magazine 22 and the base magazine 23. Only one is pushed at a time for the welding operation. Subsequently, the pushed top seat or base will move to the positioning block 24. At this time, the pushed top seat or base is clamped by the pneumatic gripper 2 27. Here, the pneumatic gripper 2 27 is pre-moved to the positioning block 24. Then, the feeding servo cylinder 2 26 drives the clamped top seat or base to move to the axial position of the pneumatic self-centering gripper 35. Then, the servo cylinder 3 36 is used to push the pneumatic self-centering gripper 35 to move horizontally, so that the pneumatic self-centering gripper 35 is docked with the top seat or base and clamped and fixed. After clamping and fixing, the pneumatic self-centering gripper 35 is controlled to retreat a certain distance, so that the feeding servo cylinder 2 26 drives the pneumatic gripper 2 27 to move back to its original position. Then, the pneumatic self-centering gripper 35 moves forward again to drive the top seat or base to fit with the end of the filter tube at the self-centering gripper 2 31. At the moment of contact, because the conductive copper bars 47 on both sides are positive and negative copper bars respectively, and the grippers on both sides are also made of copper, so at the moment of contact, current and voltage will be released to complete the welding operation;After welding is completed, the self-centering jaw 1 30, the self-centering jaw 2 31, and the pneumatic self-centering jaw 35 all reset and release. The pneumatic jaw 1 14 still remains in the clamping state with the filter tube. Then, the feeding servo cylinder 1 50 is started to drive the filter tube to reset and move to the side of the inclined material rack 1. Subsequently, the receiving cylinder 15 that originally descended drives the receiving plate 18 to reset and rise, and then the support action for the filter tube is realized through the two receiving plates 18. The pneumatic jaw 1 14 then releases. Then, the two receiving cylinders 15 synchronously descend to drive the filter tube to realize the blanking 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 to the blanking slide rail 19. At this time, the staff only needs to take out the filter tube, turn it 180 degrees, and put it into the material bin 2 again, then the above operations can be repeated to complete the welding action of the other end of the filter tube.;
