[0002] The bowl basket is a crucial component of a dishwasher, placed inside to support and secure dishes and other tableware. It's typically constructed from a metal bracket, which is then coated with a coating such as PA or PP to protect the surface and prevent rust.

[0003] At present, in the process of processing and manufacturing bowl baskets, it is usually necessary to weld hooks and other pendants on the bowl baskets to hang the bowl baskets on the bowl basket paint coating production line, facilitate the transportation of the bowl basket paint coating production line and more comprehensively paint and coat the surface of the bowl baskets to ensure the quality of the bowl basket paint and coating.

[0004] However, during the current welding process of the bowl basket and the hook, a worker usually uses a clamping tool with one hand to clamp the hook connection end and abut it against the bowl basket welding position, and uses a welding gun with the other hand to weld the welding position between the bowl basket and the hook connection end. The above welding method has the problems of low welding efficiency and poor welding quality, and cannot achieve standardized and large-scale welding operations.

[0005] In addition, during the processing and production of the hooks welded to the bowl basket, the staff usually places a vertical iron bar or rod on the hook bending device for bending and forming.

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-10As shown, the present invention is an automatic welding and hanging machine for a bowl and basket paint baking line, comprising a frame, on which are provided a rod conveying device 1, a hook online forming device 2, a bowl and basket clamping jig, and a welding device 3; the rod conveying device 1 is used to store the rod 100 and to convey the rod 100 to the hook online forming device 2; the hook online forming device 2 is located next to the rod conveying device 1 and is used to bend the bent portion of the rod 100 to form a hook 200; the bowl and basket clamping jig is located next to the hook online forming device 2 and is used to clamp and position the bowl basket 300, thereby making the bowl basket 300 abut against the connecting end of the hook 200 on the hook online forming device 2; the welding device 3 is located next to the hook online forming device 2 and the bowl and basket clamping jig and is used to weld the welding position between the connecting end of the bowl basket 300 and the hook 200, thereby fixedly connecting the bowl basket 300 and the connecting end of the hook 200. When the present invention is working, the rod conveying device conveys the required number of rods to the hook online forming device according to demand, and then the hook online forming device bends the bent part of the rod online to form a hook. At the same time, the staff or the robot places the bowl basket to be processed on the bowl basket clamping fixture for clamping and positioning. At this time, the bowl basket to be processed abuts against the connecting end of the hook, and the welding device welds the welding position between the bowl basket to be processed and the connecting end of the hook, and then welds and fixes the hook to the bowl basket. Finally, the bowl basket that has been welded can be removed. For this purpose, the present invention is equipped with a rod conveying device, a hook online forming device, a bowl basket clamping fixture, and a welding device on the frame, which can automatically realize the hook online forming operation and the hook and bowl basket welding operation, and has the characteristics of high welding efficiency, high degree of automation, and small space occupation.

[0038] like Figure 1-9 As shown, the hook of the present invention is formed by bending on the sub-line and integrated on the frame, avoiding the conventional method of bending and forming the split line body or purchasing the finished product hook. Because no matter whether the split line body is bent and formed or the finished product hook is purchased, there is an intermediate turnover and transportation process, which can easily cause the hook to be deformed or damaged, affecting the quality of the finished product and causing a large workload. For this reason, the present invention can ensure that the welding operation can be carried out immediately after the hook is bent and formed, and there is no turnover problem, making the present invention more integrated and having the advantages of saving labor transportation costs and simplifying process procedures.

[0039] like Figure 1-4 As shown in Figures 7-9, the rod conveying device 1 includes a storage bin 11 provided on a frame for storing the rods 100. The storage bin 11 is provided with a discharge channel 12 for discharging the rods 100 in sequence, ensuring that only one rod is conveyed by the conveying component, avoiding the simultaneous delivery of multiple rods to the hook online forming device, ensuring the normal operation of subsequent hook online forming and welding operations, and having a reasonable design.

[0040] like Figure 1-4 As shown in Figures 7-9, the rod conveying device 1 also includes a conveying component 13 provided on the frame and located between the storage bin 11 and the hook-on-line forming device 2 for conveying the rod 100 at the discharge channel 12 to the hook-on-line forming device 2.

[0041] like Figure 1-4 As shown in Figures 7-9, in order to improve the conveying efficiency, the conveying component 13 includes a conveying base plate 131 provided under the storage bin 11, and a conveying groove 132 for receiving the rod 100 discharged from the discharge channel 12 is provided on the conveying base plate 131 and located at the lower side of the discharge channel 12; the conveying component 13 also includes a pushing rod 134 that can move relative to the conveying base plate 131 to convey the rod 100 in the conveying groove 132 to the hook on the online forming device 2, and a pushing drive cylinder 133 provided on the conveying base plate 131 for driving the pushing rod 134 to move. During conveying, the pushing drive cylinder 133 drives the pushing rod 134 to push the rod 100 located in the conveying groove 132 toward the side of the hook online forming device 2 until the rod 100 is located on the hook online forming device 2, and then the pushing drive cylinder 133 drives the pushing rod 134 to reset, and a rod 200 located in the discharge channel 12 and above the conveying groove 132 falls into the output groove 132, which is convenient for the next conveying and realizes automatic blanking.

[0042] In order to enable the push rod to accurately and stably push the rod in the output groove, the driving end of the push drive cylinder 133 is provided with a push mounting plate, and the push rod 134 is provided on the push mounting plate; a guide assembly is provided between the push mounting plate and the conveying base plate 131, and the guide assembly includes a guide connecting rod provided on the conveying base plate 131 and a guide sleeve provided on the push mounting plate and capable of sliding along the length direction of the guide connecting rod, which is not shown in the figure.

[0043] like Figure 1-4 As shown in Figures 7-9, the storage bin 11 is provided with a shifting assembly 14 for shifting the rod 100 in the storage bin 11 so that the rod 100 can move toward the side of the discharge channel 12. The shifting assembly 14 can shift the rods in the storage bin to avoid the phenomenon of multiple rods being stuck in the storage bin and affecting normal material discharge, thereby facilitating material discharge.

[0044] like Figure 1-4As shown in Figures 7-9, the toggle assembly 14 includes toggle blocks 142 spaced apart and oppositely disposed on the inner sidewall of the storage bin 11, and toggle cylinders 141 disposed on the storage bin 11 and respectively configured to drive the toggle blocks 142 to move up and down relative to the storage bin 11. A discharge gap is formed between the two toggle blocks 142 to connect the inner cavity of the storage bin 11 with the discharge channel 12. During toggle operation, the toggle cylinders 141 drive the toggle blocks 142 to repeatedly move up and down relative to the storage bin 11, thereby causing the rod 100 in the storage bin 11 to move relative to the storage bin 11, thereby facilitating the rod 100 to pass through the discharge gap and enter the discharge channel 12.

[0045] like Figure 7-9 As shown, in order to facilitate the discharge of materials, each of the toggle blocks 142 is provided with an inclined toggle surface for toggling the rod 100 , and a V-shaped structure is formed between the two inclined toggle surfaces.

[0046] like Figure 9 As shown, a guide structure 15 is provided between the toggle block 142 and the storage bin 11, which enables the toggle block to move stably and smoothly along the set direction, and also enables the connection between the toggle block and the storage bin to be more stable.

[0047] like Figure 9 As shown, the guide structure 15 includes a guide protrusion 151 provided on the inner wall of the storage bin 11 and a guide groove 152 provided on the toggle block 142 and capable of allowing the guide protrusion 151 to enter and cooperate with the guide protrusion 151 for guidance.

[0048] like Figure 1-6 As shown, the hook online forming device 2 includes a mounting base 21 provided on a frame, a forming fixed die 22 provided on the mounting base 21, a forming movable die 23 rotatably provided on the mounting base 21 and located next to the forming fixed die 22 to cooperate with the forming fixed die 22 to bend and form the bending portion of the rod 100, and a movable die driving assembly 24 provided on the mounting base 21 for driving the forming movable die 23 to rotate. A conveying aisle for placing the rod 100 is formed on the mounting base 21 and between the forming fixed die 22 and the forming movable die 23; the hook online forming device 2 also includes a rod clamping assembly 25 provided on the mounting base 21 for clamping and positioning the rod 100. During bending and forming, the rod conveying device 1 conveys the rod 100 to the conveying aisle. At this time, the rod clamping assembly 25 works to clamp and position the rod, so that the rod is relatively fixed on the mounting base 21. Then the movable mold driving assembly 24 drives the forming movable mold 23 to move to press against the bending part of the rod 100 and bend it around the forming fixed mold 22 to form a hook 200, which can ensure the quality of the finished hook and the standardized bending and forming of the hook.

[0049] like Figure 1-6As shown, the movable mold drive assembly 24 includes a rotating shaft 244 rotatably mounted on the mounting base 21, the upper end of the rotating shaft 244 being relatively fixedly connected to a rotating disk 245 that rotates therewith, and the lower end of the rotating shaft 244 being relatively fixedly connected to a driven gear 243. The movable mold drive assembly 24 also includes an active rack 242 slidably mounted on the mounting base 21 and meshing with the driven gear 243 for transmission, and a rack drive cylinder 241 mounted on the mounting base 21 for driving the active rack 242 to slide. The forming movable mold 23 is eccentrically mounted on the upper surface of the rotating disk 245, and the forming fixed mold 22 is located above the rotating disk 245. The present invention uses a rack drive cylinder to drive the active rack to rotate the driven gear, thereby driving the forming movable mold to rotate relative to the forming fixed mold to cooperate with the forming fixed mold to perform online bending of the rod bent portion into a hook. The invention has the characteristics of high transmission accuracy, high load-bearing capacity, and stable and reliable operation.

[0050] In order to make the structure of the movable mold driving assembly 24 more stable, the upper end of the rotating shaft 244 is rotatably connected to the forming fixed mold 22. Figure 1-6 shown.

[0051] like Figure 1-6 As shown, in order to better clamp and position the rod and ensure that the rod is fixed relative to the mounting base for easy bending and forming, the rod clamping assembly 25 includes a clamping block 251 relatively fixedly mounted on the mounting base 21 and a clamping movable block 253 slidably mounted on the mounting base 21 and used to cooperate with the clamping block 251 to clamp and position the rod 100. The mounting base 21 is provided with a clamping drive cylinder 252 for driving the clamping movable block 253 to slide. In this embodiment, the clamping block 251 serves as a reference for the rod 100, ensuring the quality of the finished hook.

[0052] A guide mechanism is provided between the clamping movable block 253 and the mounting base 21, which is not shown in the figure. It can ensure that the clamping movable block 253 slides stably and smoothly, and ensure that the clamping movable block 253 slides along the set direction and cooperates with the clamping fixed block 251 to clamp the rod.

[0053] In order to make the clamping movable block slide more stably and smoothly relative to the mounting base, the guide mechanism includes a guide rail provided on the mounting base 21 and a guide slider provided on the clamping movable block 253 and slidably connected to the guide rail, which is not shown in the figure.

[0054] Furthermore, the cross section of the guide rail is T-shaped, and the corresponding cross section of the guide slider is adapted to the cross section of the guide rail.

[0055] In order to clamp the rod more firmly, the end of the clamping movable block 253 is provided with a limiting groove 2531 which can accommodate the rod 100 when the clamping movable block 253 abuts against the clamping fixed block 251. Figure 5 When clamping the rod, the end wall of the clamping block 251 restricts the rod from moving leftward relative to the mounting base, the upper wall and side walls of the restriction groove 2531 restrict the rod from moving upward and rightward relative to the mounting base, and the upper surface of the mounting base restricts the rod from moving downward relative to the mounting base, thus ensuring that the rod is fixed relative to the mounting base for easy bending and forming.

[0056] like Figure 1-6 As shown, for the convenience of unloading, the mounting base 21 is provided with a hook unloading device 26 for unloading the hook 200 from the hook in-line forming device 2. The hook unloading device 26 includes a unloading push rod 262 slidably mounted on the mounting base 21 and capable of pushing the hook 200 to move upward relative to the mounting base 21 and to separate from the forming fixed die 22, and an unloading driving cylinder 261 mounted on the mounting base 21 for driving the unloading push rod 262 to move. When the die is unloaded, the unloading driving cylinder 261 drives the unloading push rod 262 to push the hook 200 to move upward relative to the mounting base 21, so that the hook is upwardly removed from the forming fixed die.

[0057] The mounting base 21 is provided with a limiting hole sleeve 210 for the unloading push rod 262 to pass through, which can enable the unloading push rod 262 to move stably relative to the mounting base 21, and at the same time ensure that the unloading push rod moves along the set direction to accurately push the hook.

[0058] In order to improve welding efficiency, the welding device 3 includes a lower electrode 33 arranged on the frame and an upper electrode 32 arranged above the lower electrode 33 and capable of moving relative to the lower electrode 33. A welding space for the bowl basket and the hook to enter is formed between the lower electrode 33 and the upper electrode 32. The welding device 3 also includes an electrode driving cylinder 31 arranged on the frame for driving the upper electrode 32 to move.

[0059] Working principle:

[0060] First, the rods in the storage bin pass through the discharge channel and fall into the output groove 132. Then, the push drive cylinder 133 drives the push rod 134 to push the rod 100 in the conveying groove 132 toward the side of the hook-on online forming device 2 until the rod 100 is located on the conveying aisle of the mounting base 21. At this time, the rod 100 abuts against the side wall of the forming fixed mold 22, and the forming fixed mold 22 acts as a reference.

[0061] Then, the clamping drive cylinder 252 drives the clamping movable block 253 to move relative to the mounting base 21 toward the clamping fixed block 251 until the clamping movable block 253 cooperates with the clamping fixed block 251 to clamp the rod 100, and the rod is fixed relative to the mounting base.

[0062] Then, the rack drive cylinder 241 drives the active rack 242 to drive the driven gear 243 and the rotating shaft 244 to rotate, that is, the rotating disk 245 rotates to drive the forming movable mold 23 to rotate around the forming fixed mold 22. In the above process, the bent portion of the rod 100 of the forming movable mold 23 rotates around the forming fixed mold 22 and bends to form the hook 200.

[0063] At the same time, a worker or a robot places the basket on a basket clamping fixture for clamping and positioning. At this point, the basket abuts against the hook connection end, so that the welding position between the basket and the hook connection end is within the welding space. Then, the electrode driving cylinder drives the upper electrode 32 toward the lower electrode 31 to cooperate with the lower electrode 31 to perform welding on the welding position between the basket and the hook connection end. After welding is completed, the electrode driving cylinder drives the upper electrode 32 to move away from the lower electrode 31 to reset.

[0064] Finally, the unloading drive cylinder 261 drives the unloading push rod 262 to push the hook 200 to move upward relative to the mounting base 21, so that the hook 200 exits the forming mold. At this time, the staff or the robot can remove the bowl basket that has completed the welding operation from the bowl basket clamping fixture. For this reason, the present invention can realize automatic conveying of rods, automatic online forming of hooks, and automatic welding, and has the characteristics of high work efficiency, high degree of automation, and small space occupation.
