Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a stencil welding production line. Background Art

[0002] Pet cages are usually surrounded by stencils on all sides. Usually, the stencils have rectangular holes. The stencils are formed by superimposing multiple groups of steel wires arranged horizontally and multiple groups of steel wires arranged vertically, and are welded at the overlapping joints. At present, it is necessary to manually place the steel wires one by one at equal intervals on the fixed area, and it is easy to have errors in the spacing of the steel wires arranged in the same direction. Then, the intersections of the horizontally and vertically staggered steel wires are welded manually in sequence. The above processing is time-consuming. In addition, if it is necessary to form diamond-shaped spaces by combining horizontal and vertical steel wires, it is necessary to manually rotate the steel wires to a certain angle so that the steel wires in different directions form acute angles. However, there will be errors between the angle moved manually each time and the angle of the previous group of placed steel wires, resulting in different sizes of the finally formed diamond-shaped stencils, low yield rate, and affecting the appearance.

The docking track pushes the tray to rise, causing the docking track to dock with the second track. The tray moves along the docking track and the second track to the lower side of the receiving groove of the second track, and the second bracket receives the steel wire. Since the first track and the second track are perpendicular, the steel wires on the first bracket and the second bracket are perpendicular to each other, saving the cost of manual placement. At the same time, the rotating shaft drives the feeding wheel to rotate. The openings between the blade parts receive the steel wires falling out of the receiving groove and drive the steel wires to be sent onto the first bracket and the second bracket below. The feeding wheel rotates at a constant speed, enabling the steel wires to sequentially break away from the feeding wheel and fall downward at the same time interval. Finally, the welding assembly welds the steel wires in different directions together. Since the tray drives the first bracket and the second bracket to move at a constant speed, the steel wires falling on the first bracket and the second bracket can be arranged at equal intervals, improving the consistency of the spacing arrangement between the steel wires and reducing errors.

[0026] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model and not to limit the present utility model. Additionally, it should be noted that for the sake of convenience in description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0027] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above the", and "on the" second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the", and "under the" second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0029] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] Under the prior art, the steel wires are manually arranged horizontally and vertically to form a grid in the shape of a well. However, manually arranging multiple groups of steel wires is time-consuming. At the same time, the error of the arrangement spacing of the same-direction steel wires is likely to be inconsistent, resulting in inconsistent spacing of the finally welded mesh plate. The coincidence points of the horizontal and vertical steel wires need to be welded one by one manually, which is time-consuming.

[0031] To solve the above problems, as Figures 1 to 7 shown, the present utility model provides a mesh plate welding production line, including a conveying component, a welding component and a feeding component. The conveying component includes a first track 1, a second track 2 and a tray 3. The first track 1 passes through the welding component. The tray 3 slides on the first track 1. The second track 2 is perpendicular to the first track 1 and is higher than the first track 1. A track cylinder and a docking track 46 are installed between the first tracks 1. The track cylinder pushes the docking track 46 to move. The second track 2 is connected to the docking track 46. The tray 3 slides on the second track 2 and the docking track 46.

[0032] The tray 3 is rectangular. Rollers are installed on all four sides of the tray 3. The rollers on the opposite sides of the tray 3 can reciprocally roll on the first track 1. If it is necessary to switch to the second track 2, the docking track 46 under the rollers on the other two sides of the tray 3 needs to be aligned. Then the track cylinder rises until the tray 3 is lifted by the lower rollers and the docking track 46 is docked with the second track 2. The tray 3 can then slide from the docking track 46 into the second track 2. On the contrary, when the tray 3 returns from the second track 2 to the first track 1, the tray 3 moves onto the docking track 46. The docking track 46 descends. The rollers on the side of the tray 3 on the first track 1 contact the first track 1. Then the docking track 46 continues to descend and separates. Since the first track 1 and the second track 2 are perpendicular to each other, the steel wires 44 received on the first track 1 and the steel wires 44 received on the second track 2 will be perpendicular to each other, making the steel wires 44 placed on the tray 3 in a grid shape. By switching the tray 3 between the two tracks, the placement of the steel wires 44 is realized, saving costs instead of manual placement.

[0033] The feeding assembly includes a receiving groove 4, a rotating shaft 5, a first motor 6 and a feeding wheel 7. The first motor 6 drives the rotating shaft 5 to rotate. The feeding wheel 7 is circumferentially formed with blade portions 8. The openings 9 between the blade portions 8 are overlapped with steel wires 44. At least two groups of feeding wheels 7 are passed through the rotating shaft 5. The rotating shaft 5 is installed on the lower side of the conveying port at the bottom of the receiving groove 4. The feeding assemblies are respectively installed on the first track 1 and the second track 2. The rotating shaft 5 on the first track 1 is perpendicular to the first track 1, and the rotating shaft 5 on the second track 2 is perpendicular to the second track 2.

[0034] The storage groove 4 is filled with steel wires 44. The steel wires 44 of the storage groove 4 in the first track 1 are perpendicular to the first track 1, and the steel wires 44 of the storage groove 4 in the second track 2 are perpendicular to the second track 2. When the tray 3 moves to the lower side of the feeding assembly, the first motor 6 drives the rotating shaft 5 to rotate, and the rotating shaft 5 is also perpendicular to the track. Each group of openings 9 between the blade portions 8 faces upward. At this time, the openings 9 face the conveying port at the bottom of the storage groove 4 to receive the steel wires 44. After the steel wires 44 enter the openings 9, they rotate with the blade portions 8. When the openings 9 face downward, the steel wires 44 fall onto the first bracket 10 or the second bracket 11 on the lower side. Since the first bracket 10 moves at a uniform speed at this time, and the rotating shaft 5 also rotates at a uniform speed, the openings 9 between the blade portions 8 fall downward one by one, and the time intervals at which the steel wires 44 on the feeding wheel 7 fall are consistent, which will make the spacing between the steel wires 44 the same, thereby reducing the error caused by manual placement of the steel wires 44 and improving welding accuracy. The first motor 6 can increase the rotation speed of the rotating shaft 5, so that the arrangement of the steel wires 44 is denser and the placement forms are more diverse.

[0035] A first bracket 10 and a second bracket 11 are installed on the upper side of the pallet 3, and the loading wheel 7 is installed on the upper sides of the first bracket 10 and the second bracket 11. The first bracket 10 is parallel to the first track 1, and the second bracket 11 is parallel to the second track 2. The steel wire 44 in the storage groove 4 on the first track 1 falls onto the first bracket 10, and the steel wire 44 in the storage groove 4 on the second track 2 falls onto the second bracket 11, and the welding assembly welds the steel wire 44 on the pallet 3.

[0036] The first bracket 10 and the second bracket 11 are both provided with a groove 12, and the steel wire 44 is embedded in the groove 12. After the steel wire 44 falls from the feeding wheel 7, it will directly enter the groove 12. The groove 12 limits the steel wire 44 to prevent the steel wire 44 from shaking during welding, thereby improving the welding quality.

[0037] The second bracket 11 includes two groups, one group of second brackets 11 is fixed on the side of the tray 3 away from the welding assembly, and the other group of second brackets 11 is slidably installed on the side of the tray 3 close to the welding assembly. The second brackets 11 are parallel to each other, and both ends of the first bracket 10 are rotatably connected to the second brackets 11. A second motor 13 is installed on the side of the tray 3 close to the welding assembly. The second motor 13 drives the rotating wheel 14 to rotate, and the rotating wheel 14 abuts against the second bracket 11.

[0038] When the second motor 13 drives the rotating wheel 14 to rotate, the rotating wheel 14 will drive the second bracket 11 to move linearly along its own length direction. It should be particularly noted that a long hole is provided on the side of the first bracket 10 close to the second bracket 11 with sliding ability, and the screw passes through the long hole and is fixed on the second bracket 11. The first bracket 10 is rotationally connected to the second bracket 11 through the long hole, so that when the second bracket 11 moves, it is avoided being limited by the first bracket 10, and the first bracket 10 between the second brackets 11 can rotate accordingly. When steel wires 44 are placed on both the first bracket 10 and the second bracket 11, through the movement of the second bracket 11, the included angle between the steel wires 44 on the first bracket 10 and the second bracket 11 is an acute angle, and the grid is in a rhombus shape, making the grid shape patterns produced by the mesh plate welding production line of the present utility model more abundant; at the same time, since the steel wires 44 on the second bracket 11 are parallel to each other, when one group of the second brackets 11 moves, all the steel wires 44 will rotate by the same angle, making the included angles between all the steel wires 44 on the second bracket 11 and the steel wires 44 on the first bracket 10 the same, and changing the grid between the steel wires 44 into a rhombus shape, eliminating the error of manually placing the steel wires 44 and improving the processing accuracy.

[0039] A first slide rail 15 is installed inside the first track 1. The length direction of the first slide rail 15 is parallel to the first track 1. A third motor 16 is installed at the end of the first slide rail 15. The third motor 16 drives the first conveyor belt 17 to rotate. A first bracket 18 is installed on the first conveyor belt 17. The first bracket 18 is installed on the first slide rail 15. A first through hole is formed at the top of the first bracket 18. A first telescopic cylinder 19 is installed at the bottom of the tray 3. The first telescopic rod in the first telescopic cylinder 19 extends out and is inserted into the first through hole.

[0040] The third motor 16 drives the first conveyor belt 17 to rotate and drives the first bracket 18 to move along the first slide rail 15. When it is necessary for the tray 3 to move along the first track 1, the first telescopic rod in the first telescopic cylinder 19 extends out and is inserted into the first through hole, so that the first bracket 18 drags the tray 3 to move. By adjusting the moving speed of the first bracket 18 by the third motor 16, the distance between the steel wires 44 on the first bracket 10 can also be adjusted.

[0041] A second slide rail 20 is installed inside the second track 2. The length direction of the second slide rail 20 is parallel to the second track 2. A fourth motor 21 is installed at the end of the second slide rail 20. The fourth motor 21 drives the second conveyor belt 22 to rotate. A second bracket 23 is installed on the second conveyor belt 22. The second bracket 23 is installed on the second slide rail 20. A second through hole is formed at the top of the second bracket 23. A second telescopic cylinder 24 is installed at the bottom of the tray 3. The second telescopic rod in the second telescopic cylinder 24 extends out and is inserted into the second through hole.

[0042] When the tray 3 needs to be switched from the first track 1 to the second track 2, the first telescopic rod retracts to separate the first bracket 18 from the tray 3. Then the track cylinder rises to lift the tray 3. The second conveyor belt drives the second bracket 23 to move, aligning the second through-hole with the second telescopic rod. The second telescopic rod extends and is inserted into the second through-hole to achieve connection. Then the fourth motor 21 can drive the tray 3 to move on the second track 2. After that, the fourth motor 21 sends the tray 3 back to the docking track 46. The second telescopic rod retracts, the track cylinder descends, and the tray 3 drops onto the first track 1. The first telescopic rod continues to extend and is inserted into the first through-hole, and the first bracket 18 continues to drag the tray 3 towards the welding assembly. When the fourth motor 21 drives the tray 3 to move, the fourth can adjust the moving speed of the tray 3, and thus can adjust the spacing of the steel wires 44 on the second bracket 11, making the arrangement form of the steel wires 44 more diverse.

[0043] The welding assembly includes an upper welding head 25 and a lower welding head 26. The steel wire 44 is conveyed between the upper welding head 25 and the lower welding head 26. The upper welding head 25 is installed at the lower end of the telescopic cylinder 27. The telescopic cylinder 27 drives the upper welding head 25 to move perpendicular to the horizontal plane, sending the intersection of the steel wires 44 between the upper welding head 25 and the lower welding head 26 for welding.

[0044] The lower welding head 26 is installed on the cross beam 28. A support wheel 29 is installed on the lower side of the cross beam 28. An abutting block 30 is installed on the lower side of the support wheel 29. The abutting block 30 is in the shape of a shovel, and an inclined surface 31 is formed on the abutting block 30. The support wheel 29 abuts against the inclined surface 31. The support wheel 29 is fixed within the limit plate 32. A limit rail 45 is installed on the lower side of the limit plate 32. The propulsion cylinder pushes the abutting block 30 to move along the limit rail 45. A vertical groove 33 is formed within the limit plate 32. The abutting block 30 slides in a straight line, and the inclined surface 31 pushes the support wheel 29 to move along the vertical groove 33. The deeper the propulsion cylinder pushes the abutting block 30 to move, the higher the height of the support wheel 29, and the inclined surface 31 on the lower side of the support wheel 29 will push the support wheel 29 to move upward along the vertical groove 33, and vice versa.

[0045] The telescopic cylinder 27 enables the upper welding head 25 to move perpendicular to the horizontal plane. The propulsion cylinder pushes or retracts the limit block, causing the support wheel 29 abutting against the inclined surface 31 to move vertically up and down perpendicular to the horizontal plane, and different heights of steel wires 44 can be processed according to different heights.

[0046] The telescopic cylinder 27 is slidably installed on the top beam 34. The telescopic cylinder 27 is equipped with a first motor, which drives the first gear 35 to rotate. A first rack is installed on the top beam 34. The first gear 35 meshes with the first rack, and the length direction of the first rack is perpendicular to the first track 1.

[0047] By rotating the first motor, the upper welding head 25 can be moved along the length direction of the top beam 34. By driving the rotating wheel 14 to rotate through the second motor 13, the upper welding head 25 is moved along the length direction of the top beam 34. A second rack 37 is installed on the cross beam 28, and a second motor is installed on one side of the lower welding head 26. The second motor drives the second gear 36 to rotate, and the second gear 36 meshes with the second rack 37, enabling the lower welding head 26 to move along the cross beam 28. Through the flexible adjustment of the upper welding head 25 and the lower welding head 26, when the second bracket 11 drives the steel wire 44 on the tray 3 to overlap in a diamond shape under the drive of the rotating wheel 14, it will be necessary to adjust the welding positions of the upper welding head 25 and the lower welding head 26 in real time so that the overlapping parts of the steel wire 44 can all be welded.

[0048] The welding assembly includes two groups of fixed boxes 38. Welding elements are installed inside the fixed boxes 38. Both ends of the top beam 34 are installed on the fixed boxes 38. Vertical guide rails 39 are installed on the fixed boxes 38. The cross beam 28 is slidably installed on the vertical guide rails 39. A third rack 41 is installed on the cross beam 28, and the third rack 41 is perpendicular to the horizontal plane. A limiting shaft 40 is rotatably installed between the fixed boxes 38, and a third gear 42 is installed on the limiting shaft 40. The third gear 42 meshes with the third rack 41.

[0049] By setting the limiting shaft 40, the cross beam 28 is more stable when moving up and down. A total of four groups of the upper welding head 25 and the lower welding head 26 of the present utility model are installed, welding the steel wire 44 on the tray 3 simultaneously, improving the welding efficiency, making the processing time shorter. The first motor can independently control each group of upper welding heads 25, and the second motor can independently control each group of lower welding heads 26.

[0050] A camera 43 is installed on the fixed box 38. The camera 43 can identify the welding position. The camera 43 is connected to a controller, and the controller is electrically connected to the first motor, the second motor, the telescopic cylinder 27, and the propulsion cylinder respectively.

[0051] By flexibly controlling the first motor, the second motor, the telescopic cylinder 27, and the propulsion cylinder through the controller to adjust the positions of the upper welding head 25 and the lower welding head 26, the welding position can be automatically aligned, improving the welding accuracy.

[0052] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
