Description

Technical Field

[0001] This utility model relates to a welding device, specifically a welding device for the uprights of a flip-type shelf. Background Technology

[0002] Storage racks are an indispensable piece of equipment in modern warehouses, used to store various goods, improve warehouse space utilization, and facilitate the storage, retrieval, and management of goods. For example... Figure 2 As shown, the upright plate 4 is an important component of the shelf, consisting of uprights 41, horizontal braces 42 and diagonal braces 43. Uprights 41 are the main supporting components of the shelf, while horizontal braces 42 and diagonal braces 43 serve to connect and reinforce uprights 41, making the upright plate 4 more stable.

[0003] Uprights, cross braces, and diagonal braces are generally manufactured using welding processes. Welding points are distributed along the extension direction and on both sides of the uprights. Conventionally, each point is welded manually, which is time-consuming and labor-intensive. The applicant disclosed a warehouse upright welding machine in the text of Chinese Patent Publication No. CN218426411U. The uprights are fixed on a rotating platform, and welding guns controlled by two sets of horizontal modules sequentially weld the welding points on one side of the upright. Then, the rotating platform flips the upright flat, and the two sets of welding guns perform targeted welding on the other side. This invention can complete the welding of all points on the upright, achieving a high degree of automation. However, the rotating platform's positioning capability for the upright is insufficient; the upright's position may shift during rotation, causing deviations in the target weld point positions, thus affecting the overall strength of the upright. Simultaneously, completing the welding of all points on the upright requires the movement of two horizontal modules. There is room for further improvement in the efficiency and accuracy of the welding equipment for uprights. Utility Model Content

[0005] At least two sets of material positioning frames are connected to the tilting beam, and each set of material positioning frames positions a set of upright plates. Each set of material positioning frames includes two sets of material support beams and two sets of material positioning beams extending along the first direction. The material support beams are used to support the upright plates, and each set of material positioning beams is connected to at least one set of clamping components for positioning the upright plates on the surface of the material support beams.

[0006] The welding assembly includes four sets of welding torches disposed longitudinally and on the upper and lower sides of the welding station, and a welding torch moving mechanism that drives the welding torches to move. The welding torch moving mechanism includes a welding torch support beam and a first transverse drive module. The frame is provided with a first track extending along a first direction on the upper and lower sides of the welding station. The four sets of welding torches are connected to the first track through the welding torch support beam. The first transverse drive module drives the welding torch support beam to move along the first track from one side of the welding station to the other side.

[0007] Furthermore, the inner longitudinal side of the material support beam is provided with a baffle to prevent the column piece from falling.

[0008] Furthermore, the material support beam is equipped with a sensor to monitor whether the upright plate is in place.

[0009] Furthermore, each set of material positioning frames includes two sets of material support longitudinal beams located at both ends of the two sets of material support crossbeams. The material support longitudinal beams are provided with vertical slide rails, and the ends of the material support crossbeams are slidably connected to the vertical slide rails.

[0010] Furthermore, the first transverse drive module includes drive wheels disposed at both ends of the first track and a chain connected between the two sets of drive wheels. The drive wheels are driven to rotate by a first servo motor, and the chain is fixedly connected to the welding torch support beam.

[0011] Furthermore, the welding torch moving mechanism also includes a first vertical moving module arranged on both sides of the welding torch support beam. Each first vertical moving module is provided with a horizontal moving module along a second direction, the second direction being perpendicular to the first direction. The welding torch is connected to the output end of the horizontal moving module.

[0012] Furthermore, the frame is provided with second tracks extending along the first direction on the upper and lower sides of the welding station. A sliding plate is connected to the second track via a second transverse drive module. The welding assembly includes a wire feeder on the sliding plate.

[0013] Furthermore, the second transverse drive module includes a second servo motor mounted on a sliding plate and a rack mounted along a second track. The drive end of the second servo motor is connected to a gear, which is connected to the rack in a transmission connection.

[0014] Furthermore, the clamping assembly includes a clamping cylinder whose driving direction extends along the longitudinal beam of the material support and a pressure block connected to the drive shaft of the clamping cylinder. The fixed end of the clamping cylinder is connected to the material positioning beam.

[0015] Furthermore, the frame includes gantry columns arranged on both sides of the flip beam along the first direction, and the two ends of the flip beam are connected to the rotating shaft of the flip motor and connected to the gantry columns on both sides through bearings.

[0016] This utility model provides a welding device for uprights of a flip-type shelving unit, including a flip beam and at least two sets of material positioning frames connected to the flip beam. The material positioning frames move from the loading station to the welding station along with the flip beam. Material support beams are provided on the material positioning frames to support the uprights. A clamping component is provided on the material positioning beams to press the uprights firmly against the surface of the material support beams, ensuring that the uprights do not shift position during the flipping process. A welding assembly is also provided, comprising four sets of welding torches located above, below, and on both sides of the welding station.

[0017] The welding device provided by this utility model can complete the welding of all points of the column piece within one stroke of the welding gun moving mechanism. It has high precision and high cycle rate. When one set of material positioning frames is in the welding state, the material positioning frame of the loading station can simultaneously load and unload materials, which halves the welding time in the prior art and can significantly improve the processing efficiency of the column piece.

[0028] Column plate 4, column 41, horizontal brace 42, diagonal brace 43. Detailed Implementation

[0029] like Figure 1 The illustrated flip-type shelf upright welding device includes a frame 1 with a flip beam 112 connected to the frame 1 at both ends. The flip beam 112 extends along a first direction and can rotate around its own central axis under the drive of a flipping drive mechanism 11. The two sides of the flip beam 112 are a welding station and a loading station, respectively. A support unit includes at least two sets of material positioning frames 2 arranged in a ring around the flip beam 112. Each set of material positioning frames 2 is connected to the flip beam 112 and positions one set of uprights 4. The uprights 4 are installed at the loading station and welded at the welding station. Each set of material positioning frames 2 moves between the welding station and the loading station along with the flip beam 112. In this embodiment, two sets of material positioning frames 2 are connected to the flip beam 112 and symmetrically arranged on both sides of the flip beam 112. When one set of material positioning frames 2 is located at the welding station, the other set of material positioning frames 2 is located at the loading station.

[0030] like Figure 3 As shown, in this embodiment, the frame 1 includes gantry columns 12 arranged on both sides of the tilting beam 112 along a first direction. An electrical cabinet 13 is located outside the gantry columns 12, used to store various electrical components of the welding device. The tilting drive mechanism 11 is a tilting motor 111 mounted on the gantry columns 12. Both ends of the tilting beam 112 are connected to the rotating shaft of the tilting motor 111 and connected to the two gantry columns 12 via bearings, and are driven to rotate by the tilting motor 111.

[0031] like Figure 4As shown, each set of material positioning frames 2 includes two sets of material support beams 21 extending along the first direction, and material support longitudinal beams 22 located at both ends of the material support beams 21. The material support beams 21 and the material support longitudinal beams 22 enclose the storage area of ​​the column piece 4. The extension direction of the column 41 is the first direction. The inner surface of the material support beams 21 is flush with the outer surface of the column 41 of the column piece 4. The column piece 4 is inserted from the side area of ​​the material positioning frame 2. One set of columns 41 is placed on the material support beams 21. The column piece 4 is pushed along the first direction until one end of the column piece 4 contacts the inner surface of the material support longitudinal beam 22, thus determining the basic position of the end of the column piece 4 in the welding process. The column 41 can be moved on the material support beam 21 by manual pushing, or an electrically controlled push plate can be installed on the inner side of the material support beam 22 to automatically push the column piece 4 into contact with the material support beam 22 and position the reference welding position of the column piece 4.

[0032] The material support longitudinal beam 22 has vertical slide rails 24 on both sides of the tilting beam 112. The end of the material support crossbeam 21 is slidably connected to the vertical slide rails 24 via a lifting plate 23. The end of the material support crossbeam 21 is connected to the lifting plate 23 and moves synchronously with the lifting plate 23. The lifting plate 23 can drive the upper and lower sets of material support crossbeams 21 to move relative to each other until the two sets of material support crossbeams 21 contact the surfaces of the two sets of columns 41 respectively, so as to adjust for column pieces 4 of different specifications. The vertical movement of the lifting plate 23 can be adjusted manually or automatically controlled by setting a corresponding moving module.

[0033] Each set of material positioning frames 2 is further equipped with two sets of material positioning beams 25 located between the two sets of material support beams 21. The extension direction of the two sets of material positioning beams 25 is parallel to the first direction. Each end of each set of material positioning beams 25 is connected to a lifting plate 23, which is driven by a vertical slide rail 24 to move synchronously with the material support beams 21. The material positioning beams 25 are preferably installed on the inner side of the lifting plate 23, and the column pieces 4 are inserted from the outer side of the material positioning frame 2. The material positioning beams 25 can position the inner side of the column pieces 4 to a certain extent, further enhancing the positioning accuracy of each welding point.

[0034] Each set of material positioning frames 2 is equipped with at least one set of clamping components 26, including a clamping cylinder extending in the driving direction along the longitudinal beam 22 of the material support and a pressure block connected to the drive shaft of the clamping cylinder. The fixed end of the clamping cylinder is connected to the material positioning crossbeam 25. The clamping components 26 are used to fix the position of the column piece 4 on the material positioning frame 2. The setting position of the clamping cylinder is arranged to avoid the diagonal brace 43 and cross brace 42 to be welded. The pressure block applies a certain clamping force to the inner surface of the column 41 under the drive of the clamping cylinder. This ensures that during the flipping process of the material positioning frame 2, the position of the column 41 is strictly limited between the clamping components 26 and the material support crossbeam 21, and will not fall off the material positioning frame 2. Furthermore, a baffle 27 is provided on the longitudinal inner side of the material support crossbeam 21. The column piece 4 is inserted from the outside of the material positioning frame 2 and abuts against the surface of the baffle 27. The baffle 27 can prevent the column piece 4 from falling off during the loading stage.

[0035] Furthermore, sensors are installed on the end faces of the material support beam 21 opposite to the column plate 4. These sensors can be pressure sensors or photoelectric sensors, used to detect whether the column 41 of the column plate 4 on the support beam is in position. When the transmitter detects that the column 41 is in position, the control center sends a command to the clamping cylinder to position the column 41. Multiple sets of sensors can be set on each material support beam 21 corresponding to the length direction of the column 41. When each sensor detects that the column 41 is in position, the clamping cylinder begins positioning.

[0036] like Figure 5 and Figure 6 As shown, it also includes a welding assembly 3 for processing the welding points of the column pieces 4 on the welding station, and a welding gun moving mechanism 33 for controlling the displacement of the welding gun 31. The welding assembly 3 includes four sets of welding guns 31 disposed on the longitudinal direction and the upper and lower sides of the welding station. The upper and lower sets of welding guns 31 correspond to the connection positions of the horizontal brace 42, the diagonal brace 43 and the two sets of columns 41, respectively. The two sets of welding guns 31 on the longitudinal direction correspond to the welding points on both sides of the same connection position. Welding is performed simultaneously from both sides of the connection position to ensure the strength of the connection position.

[0037] The frame 1 has a first track 14 extending along a first direction on both the upper and lower sides of the welding station. The two ends of the first track 14 are respectively connected to the gantry column 12. Each set of first track 14 is connected to a welding gun moving mechanism 33. The welding gun moving mechanism 33 includes a welding gun support beam 34 slidably connected to the first track 14 and a first transverse drive module 35. Under the action of the first transverse drive module 35, the welding gun support beam 34 moves along the first track 14 from one end of the material to the other end. Four sets of welding components 3 are respectively connected to the two sides of the two sets of welding gun support beams 34. When the welding gun support beams 34 move, they weld each target point in sequence.

[0038] In this embodiment, the first transverse drive module 35 includes a transmission wheel 353 disposed at both ends of the first track 14 and a chain 351 connected between the two sets of transmission wheels 353. The transmission wheel 353 is driven to rotate by the first servo motor 352, and the chain 351 is fixedly connected to the welding gun support beam 34. The rotation stroke of the first servo motor 352 drives the welding gun support beam 34 to move along the first track 14.

[0039] Furthermore, the welding torch moving mechanism 33 also includes first vertical moving modules 36 arranged on both sides of the welding torch support beam 34. Each set of first vertical moving modules 36 is provided with a horizontal moving module 37 along a second direction, which is perpendicular to the first direction. The welding torch 31 is connected to the output end of the horizontal moving module 37. The vertical and horizontal moving trajectories of each set of welding torches 31 are adjusted by the first vertical moving module 36 and the horizontal moving module 37, respectively. Then, in conjunction with the first lateral moving drive module 35, the welding torch 31 is driven to move along the first direction, thereby enabling the welding torch 31 to move in any direction at each welding point position. Both the first vertical moving module 36 and the horizontal moving module 37 are linear motors.

[0040] Furthermore, in this embodiment, a second vertical moving module 38 is provided on both sides of the welding torch support beam 34. The second vertical moving module 38 adopts a screw drive structure and is driven by a manual wheel provided on the welding torch support beam 34. A first vertical moving module 36 is connected to the second vertical moving module 38. The first vertical moving module 36 is used to fine-tune the position of the welding torch 31 during the welding process, and the second vertical moving module 38 is used to manually adjust the position of the welding torch 31 to improve the adaptability of the welding torch 31 to the environment.

[0041] like Figure 7 As shown, the frame 1 is further provided with second tracks 15 extending along a first direction on the upper and lower sides of the welding station. A sliding plate is connected to the second track 15 via a second transverse drive module 39. The second transverse drive module 39 includes a second servo motor 392 mounted on the sliding plate and a rack 391 mounted along the second track 15. A gear is connected to the drive end of the second servo motor 392, and the gear 392 is drively connected to the rack 391. The sliding plate is used to place other functional components of the welding torch 31 assembly, such as the wire feed spool 32, the welding torch 31 control valve, and the cable chain. During the welding process, the sliding plate moves together with the welding torch support beam 34. The integration of all components on the sliding plate effectively prevents the solder delivery cable and other electrical cables from tangling, thereby maintaining the stability of the welding process.

[0042] In this utility model, the control valve of the welding torch 31, the welding torch moving mechanism 33, and the flipping drive mechanism 11 are all connected to the control center, and the feeding of the welding material, the movement of the welding torch 31, and the flipping of the material positioning frame 2 are adjusted according to a preset program. Based on this, the working process of this embodiment is described as follows:

[0043] S1. Loading: The flipping drive mechanism 11 is started, and the position of one set of material positioning frames 2 is adjusted to the welding station, and the position of the other set of material positioning frames 2 is adjusted to the loading station. The worker places the column plate 4 on the material support beam 21 of the material positioning frame 2, and pushes the column plate 4 along the material support beam 21 manually or mechanically until one end of the column plate 4 contacts the end of the material support beam 22.

[0044] S2, Positioning and Flipping: The sensor detects that the material is in place on the material support beam 21. Based on the sensor information, the clamping cylinder is activated to fix the position of the column piece 4. The flipping drive mechanism 11 drives the flipping beam 112 to rotate, and the column piece 4 at the loading station is flipped to the welding station.

[0045] S3, Welding: The welding torch moving mechanism 33 on both sides of the welding station starts, driving the welding torch 31 to move along the first direction from the beginning of the stroke to the end of the stroke. During the movement of the welding torch 31, the four sets of welding torches 31 weld the target points in sequence until each welding point on the column plate 4 is completed. Meanwhile, the two sets of welding torches 31 connected to the same welding torch support beam 34 weld the longitudinal sides of a welding position simultaneously.

[0046] Since the position of the column piece 4 is strictly defined, the welding torch moving mechanism 33 can move and weld according to the instructions of the predetermined program, ensuring the accuracy and consistency of the welding effect. While welding is being performed at the welding station, technicians can unload and load the column piece 4 at the loading station. Welding of all points on the column piece 4 is completed within one stroke of the welding torch moving mechanism 33. Furthermore, the welding torch moving mechanism 33 in this embodiment adopts a single-stroke cycle mode. During the welding process of one welding station, the welding torch support beam 34 moves from the beginning of the stroke to the end of the stroke and stays at the end of the stroke. During the welding process of the next welding station, it returns from the end of the stroke to the beginning of the stroke. The welding process of two column pieces 4 is considered as a complete cycle, thereby improving the operating efficiency of the entire device.

[0047] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
