[0039] In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] Please see Figures 1 to 5As shown, this invention discloses a shelving upright welding device 100 for welding upright frame assemblies 200. The upright frame assembly 200 includes a frame body 210 and connecting pieces 220. The frame body 210 is constructed from multiple independent profiles, specifically including: an upper horizontal profile 211, a lower horizontal profile 212, multiple vertical profiles 213, and multiple diagonal profiles 214. The connecting pieces 220 are flat metal plates that need to be welded to the ends of the upper horizontal profile 211 and the lower horizontal profile 212. In this embodiment, the profiles are all rectangular cross-section steel pipes, but obviously, circular pipes, C-shaped steel, or other irregularly shaped cross-section profiles can also be used.

[0041] The shelving upright welding equipment 100 mainly includes: machine body 1, tilting frame 2, automatic feeding device 3, and welding device.

[0042] The tilting frame 2 is used to place the column frame assembly 200 and switch between a first position and a second position. The tilting frame 2 is rotatably mounted on the machine body 1 via a horizontal pivot 21.

[0043] The main body of the tilting frame 2 is a rectangular frame structure, and it is provided with at least two workstations. In this embodiment, two workstations are preferably provided, namely, the first workstation 22 and the second workstation 23. The first workstation 22 and the second workstation 23 are arranged symmetrically with respect to the axis of the horizontal rotating shaft 21 at 180°. When the tilting frame 2 rotates 180°, the positions of the first workstation 22 and the second workstation 23 are interchanged, thereby realizing continuous production.

[0044] Each workstation is equipped with multiple positioning structures to position the various independent profiles that make up the main frame 210. The following detailed description uses the first workstation 22 as an example; the structure of the second workstation 23 is exactly the same.

[0045] In the first position, the first workstation 22 includes a first profile positioning frame 24 arranged vertically opposite to each other and a second profile positioning frame 25 connecting the two first profile positioning frames 24.

[0046] The first profile positioning frame 24 is a long strip-shaped component extending horizontally. Two first profile positioning frames 24 are arranged parallel to each other vertically, with the upper one used to support the upper horizontal profile 211 and the lower one used to support the lower horizontal profile 212. The upper surface of each first profile positioning frame 24 has a mounting surface, the cross-sectional shape of which matches the surface contour of the horizontal profile. In this embodiment, since the surface of the horizontal profile is concave, a corresponding protrusion is provided on the mounting surface to ensure the stability of the horizontal profile placement.

[0047] The second profile positioning frame 25 is a vertically extending plate-shaped component, with its upper and lower ends connected to two first profile positioning frames 25 respectively. The second profile positioning frame 25 serves to connect the upper and lower first profile positioning frames 24. The second profile positioning frames 25 are located on the left and right sides of the first profile positioning frames 24 to enhance structural stability.

[0048] The retainer 241 is disposed on the side where the first profile positioning frame 24 and the second profile positioning frame 25 are connected. Specifically, the extending direction of the retainer 241 is the same as that of the second profile positioning frame 25, and the retainer 241 is located in the length direction of the transverse profile. The surface of the retainer 241 is a magnetic surface. When the automatic feeding device 3 places the connecting piece 220 on the positioning plane, the bottom surface of the connecting piece 220 is in contact with the positioning plane of the retainer 241, thereby achieving the positioning of the connecting piece 220.

[0049] The positioning structure includes a first positioning device 26, which is mounted on a first profile positioning frame 24 and located on the side of the horizontal profile opposite to the connecting piece 220. The first positioning device 26 includes a first positioning cylinder and a telescopic rod. The cylinder body of the first positioning cylinder is detachably fixed to the end of the first profile positioning frame 24, and its piston rod is the telescopic rod, the axis of which is coaxial with the length direction of the horizontal profile. When the first positioning cylinder is vented, the telescopic rod extends, its end pressing against the end face of the horizontal profile, pushing the horizontal profile along its length towards the connecting piece 220 at the other end, so that the end of the horizontal profile is tightly fitted against the connecting piece 220. The first positioning device 26 can also use an electric push rod or a hydraulic cylinder instead of a cylinder; this embodiment uses a cylinder to simplify the pneumatic system.

[0050] An auxiliary positioning frame 27 is also provided between the two first profile positioning frames 24. The auxiliary positioning frame 27 extends in the same direction as the first profile positioning frame 24 and is fixed to the second profile positioning frame 25 or the retainer 241 by bolts. The number of auxiliary positioning frames 27 is at least one; in this embodiment, two auxiliary positioning frames 27 are provided.

[0051] The positioning structure also includes a second positioning device 28, which is mounted on an auxiliary positioning frame 27. The second positioning device 28 includes a second positioning cylinder and a positioning rod. The cylinder body of the second positioning cylinder is fixed to the auxiliary positioning frame 27, and the extension direction of the positioning rod is perpendicular to the length direction of the horizontal profile. Specifically, for the upper first profile positioning frame 24, the positioning rod extends vertically upwards, pressing the lower surface of the upper horizontal profile 211 from below; for the lower first profile positioning frame 24, the positioning rod extends vertically upwards, pressing the upper surface of the lower horizontal profile 212 from above. When the positioning rod extends, it presses and fixes the horizontal profile onto the mounting surface of the first profile positioning frame 24, preventing the horizontal profile from jumping or shifting during welding.

[0052] The sensor is mounted on the first profile positioning frame 24 and / or the auxiliary positioning frame 27. In this embodiment, the sensor is a proximity switch, mounted on the first profile positioning frame 24. The detection end of the sensor faces the placement area of ​​the horizontal profile, and is used to detect whether the horizontal profile has been manually placed in the predetermined position. The sensor is electrically connected (via a PLC controller) to the solenoid valve of the first positioning cylinder of the first positioning device 26 and the solenoid valve of the second positioning cylinder of the second positioning device 28. When the sensor detects that the horizontal profile has been placed in place, the PLC controller first starts the first positioning device 26, and then starts the second positioning device 28 to ensure a proper clamping sequence.

[0053] The main frame 210 also includes multiple vertical profiles 213 and multiple diagonal profiles 214, which support and connect between the upper horizontal profile 211 and the lower horizontal profile 212. In order to position these profiles, the positioning structure also includes multiple positioning elements 20 disposed on the auxiliary positioning frame 27.

[0054] Each auxiliary positioning frame 27 has multiple positioning elements 20 spaced apart along its length. The positioning elements 20 are magnetic, specifically permanent magnets or electromagnets. The ends of each vertical profile 213 and each inclined profile 214 are respectively placed on the corresponding positioning element 20 and fixed by magnetic attraction.

[0055] Furthermore, a positioning group is formed between two positioning elements 20 oppositely arranged on the two auxiliary positioning frames 27. The positioning group includes a first positioning group and a second positioning group. The line connecting the two positioning elements 20 in the first positioning group is perpendicular to the first profile positioning frame 24, and this positioning group is used to position the vertical profile 213. The line connecting the two positioning elements 20 in the second positioning group forms a non-right angle with the first profile positioning frame 24, and this positioning group is used to position the inclined profile 214. With this geometric layout, the vertical profile 213 is naturally in a vertical state, and the inclined profile 214 is naturally in an inclined state, without the need for an additional angle adjustment mechanism, and installation is convenient.

[0056] The positioning member 20 preferably has a magnetic surface, so the magnetic surface is used to fit with the vertical profile 213 or the inclined profile 214. Therefore, the magnetic surface has different orientations depending on the vertical profile 213 or the inclined profile 214 being positioned. It can be vertically fitted to the vertical profile 213 or inclinedly fitted to the inclined profile 214.

[0057] When the positioning component 20 uses an electromagnet, it can be attracted by electricity after the vertical profile 213 and the inclined profile 214 are placed in place, and released by de-energizing after welding is completed, making it easy to remove the component. However, to reduce costs, a permanent magnet can be used, relying on slight pressure during manual placement to make the end of the profile adhere to the magnet, and the magnetic force is sufficient to keep the profile from falling off during the flipping process.

[0058] The first profile positioning frame 24 is movably connected to the second profile positioning frame 25 via a retainer 241. Specifically, the second profile positioning frame 25 is provided with a vertically extending guide rail 251, and the retainer 241 has a slider 242 that cooperates with the guide rail 251 on the side facing the second profile positioning frame 25. The slider 242 can slide on the guide rail 251, thereby driving the first profile positioning frame 24 to move vertically. The two first profile positioning frames 24 can move closer or further apart from each other along the extension direction of the second profile positioning frame 25 via corresponding retainers 241, thereby changing the spacing between the upper and lower horizontal profiles.

[0059] An automatic feeding device 3 is installed on the machine body 1 and close to the first position, for automatically placing the connecting piece 220 on the workstation located at the first position.

[0060] In this embodiment, the automatic feeding device 3 includes a base 31, a first driving component 32, a receiving component 33, a second driving component 34, and a disengagement mechanism 35.

[0061] The base 31 is a rectangular metal block with a through workpiece channel 311 inside. The cross-sectional shape of the workpiece channel 311 matches the outer contour of the connecting piece 220. One end of the workpiece channel 311 is a feed port, which connects to the direct vibration feeder of the vibratory feeder or is manually fed; the other end is a discharge port, facing the retainer 241 on the workstation.

[0062] The first drive assembly 32 includes a first drive cylinder and a push rod. The cylinder body of the first drive cylinder is fixed to the base 31 and located on one side of the workpiece channel 311. The push rod is connected to the piston rod of the first drive cylinder and can extend into the workpiece channel 311. After the first drive cylinder is vented, the push rod pushes the connecting piece 220 along the workpiece channel 311, pushing the connecting piece 220 from the feed port to the vicinity of the discharge port.

[0063] The receiving member 33 is disposed on the opposite side of the workpiece channel 311. The receiving member 33 is a plate-shaped component, and an adsorption element is provided on the side facing the workpiece channel 311. The adsorption element is a vacuum suction cup or an electromagnet. In this embodiment, a vacuum suction cup is used to gently adsorb the surface of the connecting piece 220 without causing scratches. The back side of the receiving member 33 is connected to the second drive assembly 34.

[0064] The second drive assembly 34 includes a second drive cylinder, the cylinder body of which is fixed to the base 31 or an external bracket, and the piston rod is fixedly connected to the receiving member 33. The extension and retraction direction of the piston rod of the second drive cylinder is perpendicular to the axis of the workpiece channel 311. In the initial state, the receiving member 33 is located directly in front of the outlet of the workpiece channel 311, blocking the outlet. When the first drive assembly 32 pushes the connecting piece 220 to the outlet, the front end of the connecting piece 220 contacts the adsorption member 331, and the adsorption member initiates vacuum adsorption, holding the connecting piece 220 on the receiving member 33. Then, the second drive cylinder drives the receiving member 33 and the connecting piece 220 to move together, opening the outlet of the workpiece channel 311, and simultaneously moving the connecting piece 220 out of the workpiece channel 311 area. At this time, the connecting piece 220 and the receiving member 33 enter above the first profile positioning frame 24 and are close to the retainer 241.

[0065] A release mechanism 35 is mounted on the receiving member 33. The release mechanism 35 includes a third drive cylinder and a push-pull member. One or more through holes are provided on the receiving member 33, and the push-pull member passes through these through holes and connects to the back of the adsorption member. The cylinder body of the third drive cylinder is fixed to the back of the receiving member 33, and its piston rod is connected to the push-pull member. Once the receiving member 33 has been moved into position, the third drive cylinder drives the push-pull member forward, pushing the adsorption member along with the connecting piece 220 forward relative to the receiving member 33 until the connecting piece 220 adheres to the adsorption surface of the retainer 241. At this point, the retainer 241 at the workstation is in place, and the connecting piece 220 is precisely positioned.

[0066] After placement, the third drive cylinder reverses its direction, pulling the adsorption component back to the position where it adheres to the receiving component 33; the second drive cylinder reverses its direction, moving the receiving component 33 back to the position where it blocks the outlet of the workpiece channel 311; the first drive assembly 32 can then push the next connecting piece 220. This cycle continues.

[0067] The automatic feeding device 3 is slidably connected to the machine body 1. Specifically, a sliding block is provided at the bottom of the base 31, and a linear guide rail is provided on the machine body 1. The sliding block and the linear guide rail are slidably engaged. In this way, when no material is being fed, the automatic feeding device 3 can be positioned on the outside of the first position, avoiding interference with the tilting frame 2.

[0068] To improve production efficiency, this embodiment includes two automatic feeding devices 3, which are respectively located near the upper and lower first profile positioning frames 24. Each automatic feeding device 3 operates independently, supplying connecting pieces 220 to the ends of the upper horizontal profile 211 and the lower horizontal profile 212.

[0069] Of course, existing automatic feeding devices, such as the combination of vibratory feeders and robotic arms, can also be used, and there are no restrictions on this.

[0070] The welding device is movably mounted on the machine body 1 and close to the second position. The welding device includes a first welding device 41 and a second welding device 42.

[0071] The first welding device 41 is used to weld the joints between multiple profiles, namely the welds between the upper horizontal profile 211 and the vertical profile 213, the upper horizontal profile 211 and the inclined profile 214, the lower horizontal profile 212 and the vertical profile 213, and the lower horizontal profile 212 and the inclined profile 214.

[0072] The second welding device 42 is used to weld the connection between the frame body 210 and the connecting piece 220, namely the weld between the end of the upper horizontal profile 211 and the connecting piece 220, and the weld between the end of the lower horizontal profile 212 and the connecting piece 220.

[0073] The sliding movements of the first welding device 41 and the second welding device 42 are coordinated and controlled by a PLC controller. After the tilting frame 2 rotates the frame body 210 to be welded to the second position, the first welding device 41 and the second welding device 42 automatically move to the welding starting point according to the preset welding program, and sequentially complete the welding of all welds. Since they can move along the length of the profile, they can cover the entire welding area of ​​the frame and adapt to products of different lengths. When welding is not required, they move to the outer periphery of the second position to avoid affecting the tilting.

[0074] In summary, the shelving column welding equipment 100 of the present invention, by setting up a flipping frame 2 and at least two workstations, and configuring an automatic feeding device 3 and a welding device corresponding to the first and second positions respectively, realizes parallel operation of feeding and welding, which greatly improves production efficiency. In addition, multiple positioning structures are set on each workstation, which can position multiple independent profiles respectively, thereby adapting to the erection and welding of bulk frame bodies, and solving the technical bottleneck of existing flipping frame welding equipment that can only handle single workpieces.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
