Description

Technical Field

[0001] This invention relates to the field of environmental protection box welding technology, and specifically to an automatic welding device for hanging ring type environmental protection boxes. Background Technology

[0002] With the increasing global awareness of environmental protection and the increasingly stringent environmental regulations, the environmental protection equipment manufacturing industry has ushered in rapid development. As a convenient and hygienic waste collection and transfer device, the hanging ring type environmental protection bin is widely used in urban and rural waste sorting and disposal points, industrial parks, communities and other scenarios. With its advantages such as contactless disposal and leak-proof sealing, it effectively reduces secondary pollution during waste transfer and has become an important part of the environmental governance system. In the existing technology, environmental protection bins usually need to have the four side plates welded together.

[0003] For example, patent document CN222176398U discloses an auxiliary positioning device for welding processing in the production of environmentally friendly boxes. It includes: a first limiting groove on the outward side of a front positioning plate; a first limiting block fixedly connected below the front positioning plate; a sliding block fixedly connected to the outward side of a magnetically attached positioning plate; and a threaded connection between the magnetically attached positioning plate and a threaded rod. The beneficial effects are: two environmentally friendly box side plates are adsorbed onto the left and right magnetically attached positioning plates, and another environmentally friendly box side plate is placed on the front positioning plate. Shaking the handle rotates the gears, causing the two front positioning plates to move and clamp the environmentally friendly box side plates. Starting the motor rotates the worm gear, causing the threaded rod to rotate, moving the magnetically attached positioning plate. Once the two environmentally friendly box side plates reach the appropriate position, the motor is turned off, the corner block is removed, and the side plates are welded. No manual positioning is required, improving the product qualification rate. It is applicable to welding environmentally friendly boxes of various sizes, and welding different sizes of environmentally friendly boxes does not require changing tooling, resulting in high coordination.

[0004] While the aforementioned patent achieves clamping and positioning of the side panels of the environmental protection box, the side panels are positioned solely by magnetic attraction, which is prone to displacement and misalignment, making it difficult to guarantee the assembly and fitting accuracy of the side panels. At the same time, the height of the positioning components is fixed, and the height of the magnetic side positioning plate is limited, making it difficult to flexibly adjust the usage height according to the height of the side panels, thus affecting the position adjustment of the side panels. In addition, after the four side panels of the environmental protection box are assembled and positioned, it is difficult to achieve continuous and orderly welding of each side, resulting in low overall welding efficiency and failing to meet the requirements of efficient and precise welding production.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic welding device for hanging ring type environmental protection boxes that can effectively solve the above-mentioned technical problems.

[0007] To achieve the objectives of this invention, the following technical solution is adopted: An automatic welding device for a hanging ring type environmental protection box includes: a fixed base and a welding robot arm disposed on one side of the fixed base; a rotating base rotatably disposed on the top of the fixed base; two sets of U-shaped seats arranged in a cross pattern on the rotating base; the rotating base is provided with a displacement mechanism for relative movement of the two sets of U-shaped seats; each U-shaped seat has a lifting mechanism in the middle, and the top of the U-shaped seat is connected to a top plate through the lifting mechanism; a clamping mechanism for limiting the position of the environmental protection box is movably disposed on one side of the top plate.

[0008] Furthermore, the displacement mechanism includes a second mounting groove and a first mounting groove, which are formed in a cross shape on the upper surface of the rotating seat. A second bidirectional lead screw is rotatably connected to the inner wall of the second mounting groove, and a first bidirectional lead screw is rotatably connected to the inner wall of the first mounting groove. One end of the second bidirectional lead screw and one end of the first bidirectional lead screw both pass through the rotating seat and are fixedly connected to a handle. Two opposing movable sleeves are threaded onto the surfaces of the second bidirectional lead screw and the first bidirectional lead screw, and the movable sleeves are respectively connected to the bottom surface of the corresponding U-shaped seat. The first bidirectional lead screw and the second bidirectional lead screw can be rotated to control the relative movement of the two sets of U-shaped seats to ensure that the sides of the side plates can fit together smoothly.

[0009] Furthermore, the depth of the second mounting groove is greater than the depth of the first mounting groove, and the first bidirectional lead screw is located above the second bidirectional lead screw.

[0010] Furthermore, the bottom surface of the U-shaped seat is provided with two first rollers, and the U-shaped seat is slidably supported on the rotating seat through the first rollers.

[0011] Furthermore, a support plate is fixedly connected to the bottom of the U-shaped seat, and two second rollers are provided at the bottom of the support plate. The second rollers slide on the rotating seat, which facilitates the side plate to move and adjust together with the U-shaped seat on the support plate, and avoids friction between the bottom of the side plate and the rotating seat.

[0012] Furthermore, the lifting mechanism includes an electric telescopic rod, the bottom end of which is fixed to the middle of the U-shaped seat, and the telescopic end of which is connected to the bottom surface of the top plate. The height of the top plate can be adjusted according to the height of the side plate to facilitate the precise clamping and positioning of the side plate using the clamping mechanism.

[0013] Furthermore, guide grooves are provided at both ends of the U-shaped seat, and guide rods are fixedly connected to both ends of the top plate, with the guide rods slidably disposed in the corresponding guide grooves.

[0014] Furthermore, the clamping mechanism includes a U-shaped plate, with its two ends hinged to the two ends of the top plate. A screw is rotatably connected to the middle of the U-shaped plate, and guide rods are provided on both sides of the screw, which are connected to the U-shaped plate. A throttle is fixedly connected to one end of the screw, and a U-shaped clamping plate is threaded onto the surface of the screw. The U-shaped clamping plate is slidably fitted onto the surfaces of the two guide rods, and the distance between the U-shaped clamping plate and the U-shaped seat can be adaptively adjusted according to the side plates of different thicknesses.

[0015] Furthermore, a motor is installed in the middle of the fixed base, and the output end of the motor is connected to the middle of the bottom surface of the rotating base. The rotation of the motor can drive the rotating base to rotate, thereby changing the welding position of the environmental protection box.

[0016] Furthermore, the bottom surface of the rotating seat is embedded with several universal balls, and the rotating seat is slidably supported on the fixed seat by the universal balls.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention, through the coordinated arrangement of a rotating seat, a U-shaped seat, a displacement mechanism, a lifting mechanism, a top plate, and a clamping mechanism, can position and clamp the side panels of environmental protection boxes of different sizes. The side panel of the environmental protection box is placed against the inner side of the U-shaped seat, and the U-shaped plate is rotated 180° inward. Then, the operator rotates the handle of the screw to control the U-shaped clamping plate to move closer to the side panel of the environmental protection box until the side panel is pressed onto the U-shaped seat, thereby ensuring that the side panel will not move arbitrarily. When the bottom of the top plate is lower than the top of the side panel, the top plate can be raised and lowered using an electric telescopic rod to position the top plate above the top of the side panel, thereby ensuring accurate positioning of the side panel. This invention, through the coordinated arrangement of a fixed base, a welding robot arm, a rotating base, a motor, and universal joints, enables the rotating base to be rotated by the motor, thereby changing the welding position of the environmental protection box on the rotating base. After the position is changed, the welding robot arm is used to weld the two sides of the environmental protection box in sequence, thus eliminating the need to move the position of the welding robot arm. After the four side plates are fixed and positioned, the four sides of the environmental protection box can be welded in an orderly manner, improving the welding efficiency of the environmental protection box.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention.

When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 8As shown, this invention relates to an automatic welding device for a ring-type environmental protection bin, comprising: a fixed base 100 and a welding robot arm 200 disposed on one side of the fixed base 100. The welding robot arm 200 is a mature existing technology, and its working principle and internal structure will not be described in detail here. It also includes: a rotating base 300, which is rotatably disposed on top of the fixed base 100, allowing the rotating base 300 to rotate on the fixed base 100, facilitating subsequent repositioning of the side panel of the environmental protection bin without requiring replacement of the welding robot arm 200. The four sides of the environmental protection box are conveniently located for welding. Two sets of U-shaped seats 501 are arranged in a cross pattern on the rotating base 300. Specifically, the four U-shaped seats 501 are positioned in four positions (front, back, left, and right) to position the four side panels of the rectangular environmental protection box. The rotating base 300 is equipped with a displacement mechanism for relative movement of the two sets of U-shaped seats 501. This mechanism allows for position adjustment of the U-shaped seats 501, enabling adaptive adjustments for side panels of different sizes of environmental protection boxes without the need to replace the U-shaped seats 501. 01. Each U-shaped base 501 is equipped with a lifting mechanism in the middle, and the top of the U-shaped base 501 is connected to a top plate 502 through the lifting mechanism. A clamping mechanism for limiting the position of the environmental protection box is movably installed on one side of the top plate 502. With the cooperation of the lifting mechanism, the top plate 502, and the clamping mechanism, when the side plate of the environmental protection box is placed inside the U-shaped base 501, observe whether the bottom of the top plate 502 is above the side plate. When the bottom of the top plate 502 is lower than the top of the side plate, the lifting mechanism can be used to move the top plate 502. Move upwards until the bottom of the top plate 502 is higher than the top of the side plate. Then swing the clamping mechanism to one side of the side plate and position the side plate to prevent it from moving randomly. This facilitates the subsequent welding of the environmental protection box side plate. In addition, the clamping mechanism and the U-shaped seat 501 can clamp side plates of different thicknesses. The machinery, parts and equipment in this device are all conventional models in the existing technology. The circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0024] The displacement mechanism includes a second mounting groove 403 and a first mounting groove 401. The second mounting groove 403 and the first mounting groove 401 are formed in a cross shape on the upper surface of the rotary seat 300. A second bidirectional lead screw 404 is rotatably connected to the inner wall of the second mounting groove 403, and a first bidirectional lead screw 402 is rotatably connected to the inner wall of the first mounting groove 401. One end of the second bidirectional lead screw 404 and one end of the first bidirectional lead screw 402 both pass through the rotary seat 300 and are fixedly connected to a handle. Two opposing movable sleeves 405 are threaded onto the surfaces of the second bidirectional lead screw 404 and the first bidirectional lead screw 402, and the movable sleeves 405 are respectively connected to the bottom surface of the corresponding U-shaped seat 501.

[0025] The relative movement of the two sets of U-shaped seats 501 can be controlled by rotating the first bidirectional lead screw 402 and the second bidirectional lead screw 404 respectively, which facilitates the combination of side panels into an environmentally friendly box and makes the operation more convenient. It can be operated according to the side panels of different sizes of environmentally friendly boxes. When the handle of the second bidirectional lead screw 404 is rotated, the two U-shaped seats 501 on the left and right sides of the rotating seat 300 are moved relative to each other. When the handle of the first bidirectional lead screw 402 is rotated, the two U-shaped seats 501 on the front and rear sides of the rotating seat 300 are moved relative to each other, so as to ensure that the side edges between the side panels can be smoothly fitted.

[0026] The depth of the second mounting groove 403 is greater than the depth of the first mounting groove 401, and the first bidirectional lead screw 402 is located above the second bidirectional lead screw 404.

[0027] It can easily separate the first bidirectional lead screw 402 and the second bidirectional lead screw 404, so that the first bidirectional lead screw 402 and the second bidirectional lead screw 404 can be rotated separately, and the rotation of the first bidirectional lead screw 402 and the second bidirectional lead screw 404 will not affect each other.

[0028] The bottom surface of the U-shaped seat 501 is provided with two first rollers 507, and the U-shaped seat 501 is slidably supported on the rotating seat 300 through the first rollers 507.

[0029] The first roller 507 ensures stable movement of the U-shaped seat 501, reduces contact friction between the U-shaped seat 501 and the rotating seat 300, and facilitates the adjustment of the position of the side of the environmental protection box.

[0030] The bottom of the U-shaped seat 501 is fixedly connected to a support plate 701. The bottom of the support plate 701 is provided with two second rollers 702, and the second rollers 702 slide on the rotating seat 300.

[0031] The side panel of the environmental protection box can be placed on the support plate 701, which facilitates subsequent movement and position adjustment along with the U-shaped seat 501. Furthermore, the second roller 702 ensures the stability of the support plate 701's movement on the rotating seat 300.

[0032] The lifting mechanism includes an electric telescopic rod 601, the bottom end of which is fixed to the middle of the U-shaped seat 501, and the telescopic end of the electric telescopic rod 601 is connected to the bottom surface of the top plate 502.

[0033] When the height of the top plate 502 needs to be adjusted, the operation of the electric telescopic rod 601 is used to raise and lower the top plate 502 by extending the telescopic end of the electric telescopic rod 601. This can be used to adjust the height of the clamping mechanism, so as to accommodate the positioning of environmental protection boxes of different heights. This makes it more flexible and convenient to use. In addition, since the rotating seat 300 will rotate on the fixed seat 100, after the electric telescopic rod 601 rotates 180° with the rotating seat 300, the rotating seat 300 will rotate 180° in the opposite direction to prevent the power cord of the electric telescopic rod 601 from getting tangled.

[0034] like Figure 5 , Figure 6 and Figure 8 As shown, guide grooves 603 are provided at both ends of the U-shaped seat 501, and guide rods 602 are fixedly connected to both ends of the top plate 502, and the guide rods 602 are slidably disposed in the corresponding guide grooves 603.

[0035] The top plate 502 and the U-shaped seat 501 can be integrated into one piece, so that the top plate 502 is stable when the U-shaped seat 501 moves. When the top plate 502 is raised or lowered by the electric telescopic rod 601, the guide rod 602 will slide up and down in the guide groove 603, thereby ensuring the stability of the raising and lowering of the top plate 502 and preventing the top plate 502 from shaking randomly.

[0036] like Figure 1 , Figure 2 , Figures 4 to 6 As shown, the clamping mechanism includes a U-shaped plate 503, with both ends of the U-shaped plate 503 hinged to both ends of the top plate 502. A screw 505 is rotatably connected to the middle of the U-shaped plate 503. Guide rods 506 are provided on both sides of the screw 505 and are connected to the U-shaped plate 503. A throttle is fixedly connected to one end of the screw 505. A U-shaped clamping plate 504 is threaded onto the surface of the screw 505 and slides on the surface of the two guide rods 506.

[0037] When the side panel of the environmental protection box rests against the inner side of the U-shaped base 501, the U-shaped plate 503 can be directly flipped outwards, thus not obstructing the side panel of the environmental protection box. Furthermore, after welding is completed, the environmental protection box can be directly removed from the rotating base 300. When the side panel rests against the inner side of the U-shaped base 501, it can be supported on the support plate 701, facilitating subsequent movement. Then, the U-shaped plate 503 is flipped inwards, and the U-shaped clamp 504 rotates at a 180° angle, allowing the U-shaped plate 503 to be stably supported. Supported on the top plate 502, the U-shaped plate 503 also rotates 180° when it flips outward. Then, the operator rotates the handle of the screw 505 to control the bottom of the U-shaped clamp 504 to approach the side plate of the environmental protection box until the side plate is pressed against the U-shaped seat 501, thus ensuring that the side plate will not move arbitrarily. Repeating the above steps, the other three side plates can be positioned on the three U-shaped seats 501 respectively, so that the side plates of each side plate are in contact, which facilitates the subsequent welding process by the welding robot arm 200.

[0038] like Figure 3 As shown, a motor 302 is installed in the middle of the fixed base 100, and the output end of the motor 302 is connected to the middle of the bottom surface of the rotating base 300.

[0039] The operation of motor 302 can drive the rotation of rotating seat 300, thereby changing the welding position of the environmental protection box on rotating seat 300. The side of the replaced environmental protection box is then welded by welding robot arm 200. There is no need to move the position of welding robot arm 200, and the four sides of the environmental protection box can be welded in sequence.

[0040] like Figure 2 As shown, a number of universal balls 301 are embedded in the bottom surface of the rotating seat 300, and the rotating seat 300 is slidably supported on the fixed seat 100 through the universal balls 301.

[0041] When the starter motor 302 drives the rotating seat 300 to rotate on the fixed seat 100, the universal ball 301 will slide on the fixed seat 100, thereby ensuring the rotational stability of the rotating seat 300 and also ensuring the stable support of the rotating seat 300.

[0042] The working principle and usage process of this invention are as follows: First, place the four side plates of the environmental protection box inside the four U-shaped seats 501 respectively, and observe whether the bottom of the top plate 502 is higher than the side plates. When the top plate 502 is lower than the top of the side plates, use the operation of the electric telescopic rod 601 to lift the top plate 502 upwards, ensuring that the top plate 502 is higher than the top of the side plates, so that each top plate 502 is higher than the top of the side plates. Then, rotate each U-shaped plate 503 inwards by 180°, so that each U-shaped clamp 504 is inside the side plate. Then, rotate the handle on the screw 505 in sequence to control the U-shaped clamp 504 to press and fix the side plates, thereby completing the positioning of the four side plates. Then, the operator rotates the first bidirectional screw 402. The throttle handle and the throttle handle of the second bidirectional lead screw 404 control the displacement of the two sets of U-shaped seats 501, so that the side plates between the four side plates are in contact. Finally, the welding robot arm 200 is used to weld the side plates between the two side plates. After one side plate is finished, the adjacent side plates are welded. When the side plate of one set is finished, the rotating seat 300 is rotated 180° by the operation of the motor 302, and the other set of side plates is rotated to be close to the welding robot arm 200. The welding robot arm 200 is then used to weld the remaining set of side plates. After the side plate welding is finished, each U-shaped plate 503 can be flipped 180° outward to release the positioning of the side plate. Finally, the welded environmental protection box can be removed.

[0043] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
