Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, in particular to a vertical annular seam welding device for a thin-walled container. Background Art

[0002] Thin-walled container is a type of container with thin and uniform wall thickness. During the production and processing of thin-walled containers, it is usually necessary to use vertical circumferential welding to weld two identical thin-walled containers into a whole. Vertical circumferential welding refers to the welding gun performing circumferential welding along the joint of the two workpieces to achieve full-position welding.

[0003] The patent with announcement number CN222492866U discloses a vertical circumferential seam welding device for thin-walled containers, including a base and a welding bracket, wherein the welding bracket is fixedly installed on one side of the upper end of the base, and a rotating motor is provided on the other side of the upper end of the base, and a rotating mounting plate is provided on the upper end of the rotating motor, and an adjusting welding structure is provided in the welding bracket; the patent relates to the technical field of welding equipment, and the adjusting welding structure adopted in the patent can firstly realize the stable installation of two annular containers through the arranged rotating mounting plate and the lifting and fixing assembly, ensure the gap at the position of the annular seam, and make it rotate at a uniform speed through the motor, so as to perform the circumferential seam welding operation on it, and through the cooperation of the arranged screw rod and the electric push rod, the height and lateral position of the welding gun can be adjusted, which can meet the welding operation of annular containers of different specifications.

[0004] However, the above technical solution still has the following deficiencies in practical application: When the welding points of the two containers are fitted together, the two containers are driven to rotate at the same time so that the welding gun is welded along the joints of the two containers. Although the welding work of the containers can be realized in this way, the welding points of the two containers need to be accurately aligned before the welding work begins. In some cases, the number of containers that need to be welded is large and they are in a scattered and stacked state. For example, the containers are stacked on the conveyor belt after the previous process and move to the welding process with the conveyor belt. At this time, the workers need to manually place the containers accurately at the welding points and adjust the orientation of the containers to ensure that the welding points of the two containers are accurately fitted together. The whole process is relatively time-consuming and labor-intensive. In addition, when the containers are automatically placed by the robot, the stacking of the containers will make it difficult for the robot to grab the containers, which also affects the smooth progress of the welding work.

[0029] Specifically, when the existing thin-wall container vertical circumferential seam welding device is used, after the welding points of the two containers are fitted, the two containers are driven to rotate simultaneously so that the welding gun 6 is welded along the joints of the two containers. Although the welding work of the container can be realized in this way, before the welding work starts, the welding points of the two containers need to be accurately aligned. In some cases, the number of containers to be welded is large and they are in a scattered and stacked state. For example, the containers are stacked on the conveyor belt after the previous process and move to the welding process with the conveyor belt. At this time, the worker needs to manually place the container accurately at the welding point and adjust the orientation of the container to ensure that the welding points of the two containers are accurately fitted. The whole process is relatively time-consuming and labor-intensive. In addition, when the container is automatically placed by a robot, it is difficult for the robot to grab the container due to the accumulation of the container, which also affects the smooth progress of the welding work. Therefore, in order to solve the above problem, the working principle of this embodiment is as follows: This embodiment is applied to welding two conical thin-walled containers of the same specifications into one body, and the welding point is the seam when the surfaces with the largest diameters of the two conical containers are fitted together. This type of container is relatively common. According to the taper of the container, the cylinder 5 37 is used to drive the adjusting ring 40 to rise and fall, so that the multiple connecting rods 41 drive the multiple adjusting rods 55 to move radially at the same time, so that the collecting plate 38 can be moved. When the collecting plate 38 moves, since the collecting cloth 39 is made of elastic material, when the collecting plate 38 moves, the size of the collecting cloth 39 between the two collecting plates 38 will also change, so that the narrowest part of the entire feeding channel matches the container specifications. The containers can only be arranged vertically through the feeding channel, but cannot pass side by side. Then, multiple containers are poured in uniformly from the top of the material discharge channel. The containers will move downward under the action of gravity until they are arranged vertically at the narrowest part of the material discharge channel. At the same time, the container at the bottom will fall onto the placement seat 25, and the bottom of the container will contact the upper end of the placement seat 25. The height of the placement seat 25 can be controlled by driving the motor 6 22 to rotate the threaded rod 23, so that part of the upper end of the container is still in the material discharge channel. At this time, the height of the cylinder 6 53 is adjusted by driving the motor 8 52 to rotate the threaded rod 3 50, so that the positioning block 54 is aligned with the second container from the bottom, and the positioning block 54 is driven to move by the cylinder 6 53, so that the positioning blocks 54 on both sides pass through the through holes 56 to position the container in the material discharge channel. The container is fixed. At this time, the placement seat 25 is driven to descend so that the container on the placement seat 25 is completely separated from the unloading channel. At this time, the opening of the container on the placement seat 25 may be facing upward or downward. Then, the cylinder 11 drives the lifting plate 13 to rise and fall, and the height of the clamping block 20 is adjusted so that the clamping block 20 is aligned with the upper side of the container. Since the container is conical, the diameters of the two ends of the container are different. Then, the cylinder 2 19 is started at the same time. The cylinder 2 19 drives the clamping block 20 to contact the container until the container is clamped. At this time, it can be detected whether the container is in an opening-up state according to the movement stroke of the two clamping blocks 20. If the opening is upward, the movement stroke of the clamping block 20 is shorter, otherwise, it is larger. If the container is open, the clamping block 20 moves upward. When the container is facing upward, the clamping block 20 clamps the container and moves the container upward so that the bottom of the container is separated from the placement seat 25, and then the motor 2 9 drives the threaded rod 10 to rotate, so that the displacement plate 3 moves horizontally on the base 1 and approaches the welding gun 6, and then the motor 3 14 drives the flip plate 26 to rotate 90 degrees, and then the motor 1 7 drives the bidirectional threaded rod 8 to rotate, so that the slide seats 4 on both sides move simultaneously and approach each other, so that the surfaces with the largest diameters of the two containers fit together, and the joint is aligned with the welding gun 6, and then the welding gun 6 is turned on to weld the joint. At the same time, the motor 4 15 drives the turntable 16 to rotate, so that the two containers can rotate synchronously, so that the joint and the welding gun 6 form a relative movement, and surrounding welding is performed;If the container opening on the placement seat 25 faces downward, the stroke information of the clamp block 20 is transmitted to the controller. After the clamp block 20 clamps the container, the motor 5 18 drives the container to flip 180 degrees, and then the container is placed on the placement seat 25 again. At this time, the above-mentioned clamp block 20 fixes the container and moves the container to weld the container. When the two containers are welded into one, the clamp block 20 is reset, and the container in the material discharge channel falls into the placement seat 25 again, and then the above-mentioned operation is repeated, and all the containers in the material discharge channel can be welded in recent years; thus, under the cooperation of the clamping and flipping mechanism and the taper adaptive material control mechanism, a plurality of messy stacked containers to be welded can be orderly separated, and the opening directions of the containers can be distinguished, so that the openings of the two containers are accurately fitted, and then the welding work is carried out, avoiding the situation that the number of containers to be welded is large and they are in a scattered and stacked state, and the workers need to manually place the containers accurately at the welding position, saving manpower, and also avoiding the situation that when the container is automatically placed by the robot, the robot is difficult to grab the container due to the accumulation of the container, thereby affecting the smooth progress of the welding work. ;

[0030] In this embodiment, Figure 4-Figure 6 , Figure 8 , Fig. 9 As shown, the placement seat 25 is also provided with a groove alignment auxiliary mechanism; The groove alignment auxiliary mechanism includes a rotating ring 24 which is sleeved on the outer ring of the placement seat 25 and rotatably connected thereto, a connecting plate 30 is fixedly connected to one side of the upper end surface of the rotating ring 24, a cylinder four 31 is fixedly connected to one side of the upper end of the connecting plate 30, a connecting block 32 is fixedly connected to the piston end of the cylinder four 31, two spring dampers 33 are fixedly connected to one side of the connecting block 32, a surrounding plate 34 is fixedly connected to the piston end of the spring damper 33, an embedded block 35 is fixedly connected to one side of the surrounding plate 34, a fixing ring 2 42 is fixedly connected to the upper end surface of the placement seat 25, a plurality of radial rods 47 are radially distributed and slidably connected to the fixing ring 2 42, and a limiting ball 48 is rotatably provided at one end of the radial rod 47.

[0031] A gear 57 is rotatably provided on one side of the lower end surface of the placement seat 25, and tooth blocks are evenly provided on the inner ring of the rotating ring 24. The gear 57 is meshed with the tooth blocks on the inner ring of the rotating ring 24. A motor 7 49 is fixedly connected to one side of the lower end surface of the placement seat 25, and the output end of the motor 7 49 is fixedly connected to the gear 57.

[0032] A connecting rod 24 is rotatably provided at one end of the radial rod 47, an adjusting ring 24 is rotatably provided at one end of the connecting rod 24, a sliding column 45 is fixedly connected to one side of the adjusting ring 243, the sliding column 45 is slidably connected to the fixing ring 242, a spring 46 is sleeved on one side of the sliding column 45, the upper end of the spring 46 is fixedly connected to the adjusting ring 243, and the lower end is fixedly connected to the fixing ring 242, both sides of the upper end surface of the base 1 are fixedly connected to fixing rods 27, one side of the upper end of the fixing rod 27 is fixedly connected to a cylinder 3 28, a pressure block 29 is fixedly connected to the piston end of the cylinder 3 28, and the pressure block 29 is aligned with the edge of one side of the adjusting ring 243.

[0033] Specifically, in the above embodiment, although the two container end faces can be precisely aligned, in some cases, grooves are provided on the surface of some containers, and the grooves can facilitate the installation of the container and other components. During welding, the grooves of the two containers also need to be aligned and form a complete groove. In the above embodiment, when the container end faces are precisely aligned, the grooves on the surface may not be aligned, thereby affecting the welding effect. Therefore, in order to solve the above problem, the working principle of this embodiment is as follows: Before the container falls onto the placement seat 25, the cylinder three 28 drives the pressure block 29 to move downward and squeeze the adjusting ring two 43, and the sliding column 45 slides on the fixed ring two 42, then the multiple connecting rods two 44 simultaneously drive the multiple radial rods 47 to move, so that the limiting ball 48 is away from the axis of the placement seat 25. When the container falls onto the placement seat 25, the pressure block 29 is driven to move away from the adjusting ring two 43, and the adjusting ring two 43 is reset under the action of the spring 46, so that the limiting ball 48 fits with the outer wall of the container, and the container is limited by the limiting ball 48. Then, the cylinder four 31 is used to drive the connecting block 32 to move, so that the embedded block 35 fits with the surface of the container, and the spring damper 33 is deformed due to the mutual compression between the embedded block 35 and the surface of the container, and then the motor seven 49 is used to drive the gear 57 to rotate, so that the rotating ring 24 rotates. The embedded block 35 rotates, and slides along the surface of the container. When the embedded block 35 moves to the groove of the container, the embedded block 35 will be embedded in the groove under the action of the spring damper 33. At this time, the embedded block 35 continues to make a circular motion, and the embedded block 35 will drive the container to rotate due to the abutment between the container groove, and the container is limited between a plurality of limiting balls 48, which can not only ensure that the axis of the container is aligned with the axis of the placement seat 25, but also does not affect the rotation of the container. After the embedded block 35 rotates one circle, the position of the embedded block 35 is the position of the groove. At this time, through the container orientation adjustment work in the above embodiment, when the two container end faces are fitted, their grooves are also aligned to form a completed groove, thereby avoiding the situation where welding is performed due to the misalignment of the two container grooves, thereby affecting the welding quality.

[0034] Working principle: According to the taper of the container, the cylinder 5 37 is used to drive the adjustment ring 40 to rise and fall, so that multiple connecting rods 41 drive multiple adjustment rods 55 to move radially at the same time, so that the collecting plate 38 can move. When the collecting plate 38 moves, since the collecting cloth 39 is made of elastic material, when the collecting plate 38 moves, the size of the collecting cloth 39 between the two collecting plates 38 will also change, so that the narrowest part of the entire feeding channel matches the container specifications. The containers can only be arranged vertically through the feeding channel, but cannot pass side by side. Then, multiple containers are poured in uniformly from the top of the feeding channel, and the containers will move downward under the action of gravity until they are arranged vertically at the bottom. The narrowest part of the material channel, at the same time, the lowermost container will fall onto the placement seat 25, the bottom of the container will contact the upper end of the placement seat 25, and the height of the placement seat 25 can be controlled by the motor 6 22 driving the threaded rod 23 to rotate, so that the upper part of the container is still in the material channel. At this time, the height of the cylinder 6 53 is adjusted by the motor 8 52 driving the threaded rod 3 50 to rotate, so that the positioning block 54 is aligned with the second container from the bottom, and the positioning block 54 is driven by the cylinder 6 53 to move, so that the positioning blocks 54 on both sides pass through the through hole 56 to fix the container in the material channel. At this time, the placement seat 25 is driven to descend, so that the container on the placement seat 25 The container on the loading platform is completely separated from the unloading channel. At this time, the opening of the container on the placement seat 25 may be facing upward or downward. Then, the cylinder 11 drives the lifting plate 13 to rise and fall, and the height of the clamping block 20 is adjusted to align the clamping block 20 with the upper side of the container. Since the container is conical, the diameters of the two ends of the container are different. Then, the cylinder 2 19 is started at the same time. The cylinder 2 19 drives the clamping block 20 to contact the container until the container is clamped. At this time, it can be detected whether the container is in the opening upward state according to the movement stroke of the two clamping blocks 20. If the opening is upward, the movement stroke of the clamping block 20 is shorter, otherwise, it is larger. If the container opening is upward, the clamping block 20 clamps the container. The container is moved upward so that the bottom of the container is separated from the placement seat 25, and then the motor 2 9 drives the threaded rod 10 to rotate, so that the displacement plate 3 moves horizontally on the base 1 and approaches the welding gun 6, and then the motor 3 14 drives the flip plate 26 to rotate 90 degrees, and then the motor 1 7 drives the bidirectional threaded rod 8 to rotate, so that the slide seats 4 on both sides move simultaneously and approach each other, so that the surfaces with the largest diameters of the two containers fit together, and the joint is aligned with the welding gun 6, and then the welding gun 6 is turned on to weld the joint. At the same time, the motor 4 15 drives the turntable 16 to rotate, so that the two containers can rotate synchronously, so that the joint and the welding gun 6 form a relative movement, and surrounding welding is performed;If the container opening on the placement seat 25 faces downward, the stroke information of the clamp block 20 is transmitted to the controller. After the clamp block 20 clamps the container, the motor 5 18 drives the container to flip 180 degrees, and then the container is placed on the placement seat 25 again. At this time, the above-mentioned operations of fixing the container with the clamp block 20 and moving the container are repeated to weld the container. When the two containers are welded into one, the clamp block 20 is reset, and the container in the material discharge channel falls into the placement seat 25 again, and then the above-mentioned operations are repeated, and all the containers in the material discharge channel can be welded in recent years; thereby, under the cooperation of the clamping and flipping mechanism and the taper adaptive material control mechanism, multiple messily stacked containers to be welded can be separated in order, and The opening directions of the containers are distinguished so that the openings of the two containers are accurately fitted together before welding, thereby avoiding the situation where a large number of containers to be welded are in a scattered and piled state, and workers need to manually place the containers accurately at the welding position, saving manpower, and also avoiding the situation where the robot is difficult to grab the containers due to the accumulation of containers when the containers are automatically placed by the robot, thereby affecting the smooth progress of the welding work. In addition, before the container falls onto the placement seat 25, the cylinder 3 28 drives the pressure block 29 to move downward and squeeze the adjustment ring 2 43, and the sliding column 45 slides on the fixed ring 2 42, then the multiple connecting rods 2 44 simultaneously drive the multiple radial The rod 47 moves to make the limiting ball 48 away from the axis of the placement seat 25. When the container falls onto the placement seat 25, the pressing block 29 is driven to move away from the adjusting ring 23. The adjusting ring 23 is reset under the action of the spring 46, and the limiting ball 48 fits with the outer wall of the container. The container is limited by the limiting ball 48. Then, the cylinder 431 is used to drive the connecting block 32 to move, so that the embedding block 35 fits with the surface of the container, and the spring damper 33 is deformed due to the mutual compression between the embedding block 35 and the surface of the container. Then, the motor 7 49 drives the gear 57 to rotate, so that the rotating ring 24 rotates, and the embedding block 35 slides along the surface of the container. When the embedding block 35 moves to the groove of the container, the embedding The block 35 will be embedded in the groove under the action of the spring damper 33. At this time, the embedded block 35 continues to make a circular motion, and the container will be driven to rotate due to the abutment between the embedded block 35 and the container groove, and the container is limited between the multiple limiting balls 48, which can ensure that the axis of the container is aligned with the axis of the placement seat 25 without affecting the rotation of the container. After the embedded block 35 rotates one circle, the position of the embedded block 35 is the position of the groove. At this time, through the container orientation adjustment work in the above embodiment, when the two container end faces are fitted, their grooves are also aligned to form a completed groove, thereby avoiding the situation where welding is performed due to the misalignment of the two container grooves, thereby affecting the welding quality. ;
