Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment for furniture columns, and specifically to an intelligent welding equipment for metal furniture columns. Background Technique

[0002] Metal furniture is iron art furniture with metal columns, plates or rods as the main framework. Metal fittings in metal furniture, such as columns, mainly play a role in support and load-bearing. In order to facilitate the subsequent assembly of the column with other fittings of the metal furniture, generally, a welding method is used to weld multiple connectors to the column for subsequent connection and assembly. When welding, an intelligent welding equipment for metal furniture columns is usually used to melt and connect the side of the connector and the end of the column together by the high temperature generated by the electric arc.

[0003] However, when the existing intelligent welding equipment for metal furniture columns welds the column and the negative film connector, a small amount of waste residue will be generated. The long-term adhesion of these waste residues at the welding joint of the column and the negative film will reduce the processing quality. Usually, after the welding work is completed by the intelligent welding equipment for metal furniture columns, the column will be placed in a special cleaning area for cleaning. It is not convenient to transport the column and clean the waste residue at the end of the column at the same time, which increases the working time and labor consumption and prolongs the downtime. For this reason, we have proposed an intelligent welding equipment for metal furniture columns. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent welding equipment for metal furniture columns to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present invention provides the following technical solution: An intelligent welding device for metal furniture columns, including a machine body and a waste residue tank. One side of the machine body is connected with a discharge platform. The waste residue tank is opened on the surfaces at both ends of the discharge platform. A cleaning mechanism is installed inside the discharge platform and the waste residue tank. In the slot in the middle of the discharge platform, a driven synchronous roller and a driving synchronous roller are installed through bearings. A transmission synchronous belt is sleeved outside the driven synchronous roller and the driving synchronous roller. Push plates are fixedly installed at equal intervals on the outside of the transmission synchronous belt. Both ends of the driving synchronous roller are fixedly connected with transmission shafts. A cleaning motor connected to the transmission shaft through a coupling is installed outside the discharge platform. A mounting seat is fixed on the surface of the discharge platform close to the cleaning mechanism, and one side of the mounting seat is connected to the cleaning mechanism. The cleaning mechanism includes a turntable connected to the mounting seat through a bearing. A cleaning brush is installed through a bearing on the inner side of the turntable away from the mounting seat. A small gear is fixedly sleeved at one end of the cleaning brush. A toothed disc is fixedly connected to the surface of the mounting seat close to the small gear. A driven sprocket is fixedly sleeved at one end of the turntable close to the mounting seat. A chain is meshed and sleeved outside the driven sprocket. One end of the chain away from the driven sprocket is meshed and sleeved with a driving sprocket. A discharge guide plate is fixed at the connection between the machine body and the discharge platform.

[0006] Preferably, the driving sprocket is fixedly sleeved with the transmission shaft. A conveying mechanism is arranged above the machine body. The conveying mechanism includes an electric slide rail opened above the machine body.

[0007] Preferably, a sliding frame is electrically slidably connected inside the electric slide rail. Cylinders are fixed at both ends of the sliding frame. The output ends of the cylinders are fixedly connected with brackets.

[0008] Preferably, a gantry is welded on the surface of the machine body. Welding components are installed at both ends of the gantry. Support frames are installed through bearings on the surfaces at both ends of the gantry close to the welding components. A placement rack is fixed on one side surface of the support frame. A rotating motor connected to the support frame through a coupling is installed on the outer wall of the gantry.

[0009] Preferably, an ejecting mechanism is installed inside the placement rack and the support frame. The ejecting mechanism includes a telescopic groove opened inside the support frame.

[0010] Preferably, a ejecting rod slidably penetrates through the inside of the telescopic groove. An ejecting spring is sleeved outside the ejecting rod. One end of the ejecting rod is fixedly connected with an ejecting plate.

[0011] Preferably, guide blocks are fixedly connected to both ends of the ejecting plate. Guide grooves are opened on the inner wall of the placement rack close to the guide blocks.

[0012] Preferably, the guide block is slidably connected to the guide groove. A through opening is provided on one side of the placement rack. Both ends of the support frame are movably connected to a stop block through a rotating seat.

[0013] Preferably, one side of the stop block is connected to an electric push rod through a movable shaft, and the other end of the electric push rod is connected to the support frame through a movable shaft.

[0014] Preferably, a column base plate is provided inside the placement rack. One side of the column base plate is welded with a column body, and the column body is located inside the bracket.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This intelligent welding equipment for metal furniture columns can place multiple column base plates at one time. The ejection mechanism is used to push the column base plates. When the column body drives the column base plate to reach above the unloading table, the cleaning mechanism sweeps and brushes the waste residue at the welding joint of the column base plate and the column body through a series of transmissions, making the waste residue loose. Finally, most of the waste residue falls into the waste residue tank for collection, which can reduce the adhesion of waste residue on the column body. Moreover, the conveying mechanism and the conveyor synchronously convey the column body, facilitating the taking of the welded column body, which can minimize the equipment downtime, maintain the continuity of the production line, and is beneficial to improving the working efficiency of the intelligent welding equipment for metal furniture columns.

[0016] 1. For this intelligent welding equipment for metal furniture columns, after the column body drives the column base plate to reach above the unloading table, the cleaning mechanism makes the turntable drive the cleaning brush to perform a circular rotational motion around the column base plate through a series of transmissions. And through the meshing connection of the gear disk and the small gear, the small gear drives the cleaning brush to rotate self - rotationally, which can sweep and brush the waste residue at the welding joint of the column base plate and the column body, making the waste residue loose. Finally, most of the waste residue falls into the waste residue tank for collection, which can reduce the adhesion of waste residue on the column body, reduce labor consumption, and improve the working quality of the intelligent welding equipment for metal furniture columns; 2. For this intelligent welding equipment for metal furniture columns, after welding the column base plates at both ends of the column body, the conveying mechanism drives the column body to reach the upper surface of the unloading guide plate. Subsequently, the column body rolls down along the inclined surface of the unloading guide plate. Finally, the column body rolls onto the conveyor synchronous belt. Then, while the cleaning mechanism is moving, the transmission shaft makes the driving synchronous roller drive the conveyor synchronous belt to rotate. The conveyor synchronous belt pushes the column body away from the unloading guide plate through the push plate, facilitating the taking of the column body. The cleaning mechanism, the conveying mechanism, and the conveyor synchronous belt cooperate with each other, which can clean and collect the waste residue while stably unloading, can minimize the equipment downtime, maintain the continuity of the production line, and is beneficial to improving the working efficiency of the intelligent welding equipment for metal furniture columns; 3. For this intelligent welding equipment for the metal furniture column, multiple column negatives are inserted into the placement rack. Since the surface of the ejector plate in contact with the column negative is an inclined structure, it is convenient for the column negative to squeeze the ejector plate and enter the placement rack. After the welding work is completed, the column body is moved to the unloading guide plate through the bracket. At the same time, the electric push rod drives the block located at the through-port to rotate. Subsequently, the column body drives the column negative to move out from the through-port. Then, a gap for one column negative will be vacated in the placement rack. The ejector mechanism then pushes the column negative, and the staff can put multiple column negatives into the placement rack at one time, reducing the working time and improving the convenience of the intelligent welding equipment for the metal furniture column.

Detailed implementation manners

[0019] 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 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.

[0020] Please refer to Figures 1 - 3 , Figure 5 and Figures 7 - 10 , the present invention provides a technical solution: an intelligent welding device for metal furniture columns, including a machine body 1 and a waste residue tank 7. A unloading platform 2 is connected to one side of the machine body 1. A gantry 3 is welded on the surface of the machine body 1. Welding assemblies 4 are installed at both ends of the gantry 3. Support frames 6 are installed on the surfaces of both ends of the gantry 3 close to the welding assemblies 4 through bearings. A placing rack 10 is fixed on one side surface of the support frame 6. A rotating motor 5 connected to the support frame 6 through a coupling is installed on the outer wall of the gantry 3.

[0021] Please refer to Figures 1 - 6, the waste residue tank 7 is opened on the surfaces at both ends of the unloading platform 2. A cleaning mechanism 8 is installed inside the unloading platform 2 and the waste residue tank 7. A cleaning motor 11 connected to the transmission shaft 24 through a coupling is installed outside the unloading platform 2. A mounting seat 21 is fixed on the surface of the unloading platform 2 close to the cleaning mechanism 8, and one side of the mounting seat 21 is connected to the cleaning mechanism 8. The cleaning mechanism 8 includes a turntable 802 connected to the mounting seat 21 through a bearing. A cleaning brush 801 is installed inside the turntable 802 away from the mounting seat 21 through a bearing. A small gear 22 is fixedly sleeved at one end of the cleaning brush 801. A toothed disc 803 is fixedly connected to the surface of the mounting seat 21 close to the small gear 22. A driven sprocket 806 is fixedly sleeved at one end of the turntable 802 close to the mounting seat 21. A chain 804 is meshed and sleeved outside the driven sprocket 806. One end of the chain 804 away from the driven sprocket 806 is meshed and sleeved with a driving sprocket 805. The surface height of the transmission synchronous belt 20 is lower than the surface height of the unloading platform 2. The diameter of the circular rotation trajectory of the cleaning brush 801 is greater than the distance from the center of the turntable 802 to the corner of the bottom plate 15 of the column. The brush hair material of the cleaning brush 801 is selected as synthetic fiber.

[0022] During specific implementation, a small amount of waste residue will be generated when the column of the metal furniture is welding the bottom plate workpiece. If these waste residues are not cleaned in time, it will affect the processing quality, and subsequent centralized cleaning is time-consuming. When the column body 16 drives the column bottom plate 15 to roll onto the upper part of the transmission synchronous belt 20 from the unloading guide plate 17, it is blocked by the push plate 19. Then, the cleaning motor 11 drives the driving sprocket 805 to rotate through the transmission shaft 24. The driving sprocket 805 pulls the chain 804 to drive the driven sprocket 806 to rotate. Subsequently, the driven sprocket 806 drives the turntable 802 to rotate, so that the turntable 802 drives the cleaning brush 801 to perform a circular rotation movement around the column bottom plate 15. At the same time, the cleaning brush 801 drives the small gear 22 to be meshed and connected with the toothed disc 803, and the small gear 22 drives the cleaning brush 801 to rotate self. By rotating self while performing a circular rotation movement, the waste residue at the welding joint of the column bottom plate 15 and the column body 16 can be swept and brushed, making the waste residue loose. Finally, most of the waste residue falls into the waste residue tank 7 for collection, which can reduce the adhesion of waste residue on the column body 16, reduce labor consumption, and improve the working quality of the intelligent welding equipment for the column of the metal furniture.

[0023] Please refer to Figures 1 - 6, a driven synchronous roller 25 and a driving synchronous roller 23 are installed in the slot in the middle of the unloading table 2 through bearings. A transmission synchronous belt 20 is sleeved outside the driven synchronous roller 25 and the driving synchronous roller 23. Push plates 19 are fixedly installed on the outside of the transmission synchronous belt 20 at equal intervals. Both ends of the driving synchronous roller 23 are fixedly connected with transmission shafts 24. A discharge guide plate 17 is fixed at the connection between the machine body 1 and the unloading table 2. The driving sprocket 805 is fixedly sleeved with the transmission shaft 24. A conveying mechanism 18 is arranged above the machine body 1. The conveying mechanism 18 includes an electric slide rail 1802 opened above the machine body 1. A slide carriage 1801 is electrically slidably connected inside the electric slide rail 1802. Cylinders 1803 are fixed at both ends of the slide carriage 1801. The output ends of the cylinders 1803 are fixedly connected with brackets 1804. The discharge guide plate 17 is provided with a three-section continuous inclined structure.

[0024] During specific implementation, after welding the column base plates 15 at both ends of the column body 16, the electric slide rail 1802 drives the slide carriage 1801 to slide. The slide carriage 1801 drives the cylinders 1803 to move. The cylinders 1803 drive the column body 16 to move towards the discharge guide plate 17 through the brackets 1804. When the column body 16 reaches the upper surface of the discharge guide plate 17, the cylinders 1803 contract downward and drive the brackets 1804 to move downward. At this time, the surface of the discharge guide plate 17 is higher than the brackets 1804, and the column body 16 contacts the surface of the discharge guide plate 17. Subsequently, the column body 16 rolls down through the inclined surface of the discharge guide plate 17. The inclined surface of the discharge guide plate 17 is provided with three sections, which can reduce the impact when the column body 16 rolls down. Finally, the column body 16 rolls onto the transmission synchronous belt 20. Then, while the cleaning motor 11 drives the cleaning mechanism 8 to clean the waste slag at the welding part of the column body 16, the transmission shaft 24 drives the driving synchronous roller 23 to rotate. The driving synchronous roller 23 pulls the transmission synchronous belt 20 to drive the driven synchronous roller 25 to rotate. When the driving synchronous roller 23 rotates one week, the turntable 802 also drives the cleaning brush 801 to rotate one week. At the same time, the transmission synchronous belt 20 drives the push plate 19 located on its bottom surface to reach one side of the column body 16. The driving synchronous roller 23 continues to rotate. The transmission synchronous belt 20 pushes the column body 16 away from the discharge guide plate 17 through the push plate 19. And the rotation trajectory of the cleaning brush 801 is the same as the movement trajectory of the transmission synchronous belt 20, and the cleaning brush 801 will not affect the movement of the column body 16. During the movement of the column body 16, the waste slag can continue to fall into the waste slag tank 7. The staff can take the column body 16 from the transmission synchronous belt 20. The settings of the cleaning mechanism 8, the conveying mechanism 18 and the transmission synchronous belt 20 can clean and collect the waste slag while stably discharging, can minimize the equipment downtime, maintain the continuity of the production line, and are beneficial to improving the working efficiency of the intelligent welding equipment for metal furniture columns.

[0025] Please refer toFigure 1 , Figure 2 and Figures 7 - 11 , a ejecting mechanism 9 is installed inside the placing rack 10 and the support frame 6. The ejecting mechanism 9 includes a telescopic groove 907 opened inside the support frame 6. A ejecting rod 906 slides through the inner side of the telescopic groove 907. A ejecting spring 905 is sleeved outside the ejecting rod 906. One end of the ejecting rod 906 is fixedly connected to a ejecting plate 903. Guide blocks 904 are fixedly connected to both ends of the ejecting plate 903. Guide grooves 902 are opened on the inner wall of the placing rack 10 close to the guide blocks 904. The guide blocks 904 are slidably connected with the guide grooves 902. A through opening 901 is opened on one side of the placing rack 10. Both ends of the support frame 6 are movably connected with a stop block 14 through a rotating seat 12. One side of the stop block 14 is connected with an electric push rod 13 through a movable shaft. The other end of the electric push rod 13 is connected with the support frame 6 through a movable shaft. A column bottom plate 15 is arranged inside the placing rack 10. A column body 16 is welded on one side of the column bottom plate 15, and the column body 16 is located inside the bracket 1804. One side of the ejecting plate 903 is of an inclined structure. The material of the ejecting spring 905 is selected as an alloy.

[0026] During specific implementation, before welding work, it is necessary for the staff to put the column bottom plate 15 into the tooling. After the column bottom plate 15 and the column body 16 are welded, it is necessary for the staff to put another column bottom plate 15 into the tooling again, which is not convenient enough. The electric push rod 13 can be started to make the electric push rod 13 contract to pull the stop block 14. Then one end of the stop block 14 rotates around the rotating seat 12 to directly insert a plurality of column bottom plates 15 into the placing rack 10. Since the surface of the ejecting plate 903 in contact with the column bottom plate 15 is of an inclined structure, it is convenient for the column bottom plate 15 to squeeze the ejecting plate 903 and enter the placing rack 10. At the same time, the ejecting plate 903 drives the ejecting rod 906 to slide in the telescopic groove 907 and squeeze the ejecting spring 905. After the welding work is completed, the column body 16 is moved to the unloading guide plate 17 through the bracket 1804. At the same time, the electric push rod 13 drives the stop block 14 located at the through opening 901 to rotate. Then the column body 16 drives the column bottom plate 15 to move out from the through opening 901. Then a gap for one column bottom plate 15 will be vacated inside the placing rack 10. The ejecting spring 905 will rebound to drive the ejecting rod 906 to slide. The ejecting rod 906 drives the ejecting plate 903 to squeeze the column bottom plate 15 to make the two ends of the column bottom plate 15 close to the column body 16. At the same time, the ejecting plate 903 drives the guide blocks 904 to slide in the guide grooves 902, which is beneficial to the stable movement of the ejecting plate 903. Due to the extrusion of the ejecting plate 903, the staff can put a plurality of column bottom plates 15 into the placing rack 10 at one time, reducing the working time and improving the convenience of the intelligent welding equipment for the columns of metal furniture.

[0027] In summary, when using this intelligent welding equipment for metal furniture columns, multiple column negatives 15 are placed in the placement rack 10. Subsequently, the column body 16 is placed on the bracket 1804, and the conveying mechanism 18 conveys the column body 16 to the position of the column negative 15. The welding assembly 4 welds the column body 16 and the column negative 15. At the same time, the rotating motor 5 drives the support frame 6 to rotate, so as to perform circumferential welding. After welding, the conveying mechanism 18 drives the column body 16 to reach above the unloading platform 2. The cleaning mechanism 8 sweeps the waste residue, making the waste residue loose. Subsequently, the waste residue falls into the waste residue tank 7, and the cleaning mechanism 8 drives the conveyor synchronous belt 20 to rotate to convey the cleaned column body 16, facilitating the operator to unload the materials, which can minimize the equipment downtime and maintain the continuity of the production line, and is beneficial to improving the working efficiency of the intelligent welding equipment for metal furniture columns.
