[0045] In one embodiment of the present invention, Figures 1-2As shown, an automatic loading and unloading processing equipment for metal box bottoms is provided, comprising a metal box bottom processing machine 10, a metal box bottom stacking and loading device 20, and a metal box bottom linear feeding device 30. The metal box bottom processing machine 10 is provided with a processing cavity 11, and a processing platform 12 is formed below the processing cavity 11. The metal box bottom stacking and loading device 20 is provided on the side of the metal box bottom processing machine 10, and is used to supply metal box bottoms for processing on the processing platform 12 or stack the metal box bottoms processed on the processing platform 12. The metal box bottom linear feeding device 30 is installed in the metal box bottom processing machine 10, and picks up the stacked metal box bottoms in the metal box bottom stacking and loading device 20 and places them on the processing platform 12, or transports the metal box bottoms processed on the processing platform 12 and stacks them in the metal box bottom stacking and loading device 20. Specifically, if there is metal box bottom material on the metal box bottom pile loading device 20, the metal box bottom line linear feeding device 30 can extend to the metal box bottom pile loading device 20 to pick up the metal box bottom and put it into the metal box bottom processing machine 10 for processing, and then transport the processed metal box bottom to the metal box bottom pile loading device 20 for storage. For example, the metal box bottom pile loading device 20 can be arranged on both sides of the metal box bottom processing machine 10 respectively. Of course, the metal box bottom can also be taken out from other production processes through the metal box bottom linear feeding device 30 and put into the metal box bottom processing machine 10 for processing, and then the processed metal box bottom can be transported and stored on the metal box bottom pile loading device 20, thereby completing the processing of the metal box bottom.

[0046] Among them, the metal box bottom processing machine 10 can be a press, a rolling machine, a flanging machine, etc. Such mechanical equipment can realize the processing of the metal box bottom, and such mechanical equipment belongs to the existing technology and will not be described in detail here.

[0047] In one embodiment of the present invention, Figures 3-5As shown, the metal box bottom stacking loading device 20 includes a bottom plate 21, a first material rack 22, a second material rack 23 and a material rack lifting mechanism 24; the bottom plate 21 is arranged at the side and lower part of the metal box bottom processing machine 10, and the bottom plate 21 is divided into a first stacking area and a second stacking area arranged side by side, the first material rack 22 includes a first support plate 221 and a plurality of first blocking columns 222, the second material rack 23 includes a second support plate 231 and a plurality of second blocking columns 232, each of the first blocking columns 222 is vertically fixed on the first stacking area of ​​the bottom plate 21, and the first support The support plate 221 is located on the first stacking area and is provided with a first strip hole 2211 for each first blocking column 222 to pass through, and each second blocking column 232 is vertically fixed to the second stacking area of ​​the bottom plate 21. The second support plate 231 is located on the second stacking area and is provided with a second strip hole 2311 for each second blocking column 232 to pass through. In this way, the first support plate 221 can be moved up and down by the provision of the first strip hole 2211, and the second support plate 231 can be moved up and down by the provision of the second strip hole 2311. And because they are strip holes, the lengthwise positions of the first blocking column 222 and the second blocking column 232 in the first strip hole 2211 and the second strip hole 2311 can be adjusted respectively, thereby adjusting the area enclosed for stacking the metal box bottoms to meet the position limit requirements for metal box bottoms of different sizes or shapes. The material rack lifting mechanism 24 includes a material rack drive motor 241, a driving wheel 242, a driven wheel 243 and a vertical belt (not shown). The material rack drive motor 241 is fixed to the bottom of the base plate 21, the driving wheel 242 is fixed to the main shaft of the material rack drive motor 241, and the driven wheel 243 is located above the driving wheel 242 and positioned. The vertical belt is wound around the driving wheel 242 and the driven wheel 243. The first support plate 221 and the second support plate 231 are respectively connected and fixed to the two sides of the vertical belt and are arranged one above and one below. When the material rack drive motor 241 drives the vertical belt to rotate, the first support plate 221 and the second support plate 231 are driven by the vertical belt to move in opposite directions along the vertical direction. Specifically, the first support plate 221 in the first stacking area is used to stack the bottom of the metal box in the area surrounded by multiple first blocking columns 222. Similarly, the second support plate 231 in the second stacking area is used to stack metal box bottoms in the area surrounded by the plurality of second material blocking posts 232. When the first support plate 221 and the second support plate 231 are in a lower position, they can stack more metal box bottoms. The height of the first support plate 221 and the second support plate 231 is driven by the material rack lifting mechanism 24.When the rack drive motor 241 drives the driving wheel 242 to rotate, the cooperation of the driven wheel 243 can make the vertical belt rotate around the driving wheel 242 and the driven wheel 243. When the vertical belt rotates, it will pull the first support plate 221 and the second support plate 231 on the opposite sides and at a higher and lower position to move up and down. In this way, when the first support plate 221 is at the lowest position, it can be full of metal box bottoms. At this time, you can switch to the second support plate 231 to stack the metal box bottoms. In this way, the stacking position is switched to stack the metal box bottoms, ensuring the continuity and high efficiency of stacking. Similarly, the loading is the opposite. After the metal box bottoms of the first support plate 221 are loaded, the metal box bottoms of the second support plate 231 can be switched to load, achieving the continuity and high efficiency of stacking.

[0048] In this way, the metal box bottom linear feeding device 30 can pick up the metal box bottom from the first support plate 221 or the second support plate 231 to the processing platform 12 for processing, or pick up the processed metal box bottom from the processing platform 12 to the first support plate 221 or the second support plate 231 for stacking.

[0049] In one embodiment of the present invention, Figures 3-5 As shown, the material rack lifting mechanism 24 also includes a first guide column 244, a first guide sleeve 245, a second guide column 246 and a second guide sleeve 247. The first guide column 244 and the second guide column 246 are both vertically spaced and fixed between the first stacking area and the second stacking area of ​​the bottom plate 21. The top of the first guide column 244 and the second guide column 246 are connected and fixed by a top connecting block 248. The driven wheel 243 is installed at the bottom of the top connecting block 248 and is located between the first guide column 244 and the second guide column 246. The first guide sleeve 245 is slidably sleeved outside the first guide column 244 and is connected and fixed to the side of the first support plate 221. One side of the vertical belt is locked and connected to the first guide column 244. The second guide sleeve 247 is slidably sleeved outside the second guide column 246 and is connected and fixed to the side of the second support plate 231. The other side of the vertical belt is locked and connected to the second guide column 246. Specifically, the first guide post 244 and the first guide sleeve 245 cooperate to guide the lifting and lowering of the first support plate 221, while the second guide post 246 and the second guide sleeve 247 cooperate to guide the lifting and lowering of the second support plate 231. Thus, when one side of the vertical belt pulls the first guide sleeve 245 up or down along the first guide post 244, the other side of the vertical belt pulls the second guide sleeve 247 down or up along the second guide post 246, in an up-and-down motion. This allows the support plates on one side to complete their work before the support plates on the other layer can resume their work.

[0050] In one embodiment of the present invention, Figures 3-5As shown, there are two first guide posts 244, and the first guide sleeves 245 that are sleeved outside the two first guide posts 244 are connected and fixed by a first side connecting block 2451. The side of the first side connecting block 2451 is locked and connected to one side of the vertical belt. There are two second guide posts 246, and the second guide sleeves 247 that are sleeved outside the two second guide posts 246 are connected and fixed by a second side connecting block 2471. The side of the second side connecting block 2471 is locked and connected to the other side of the vertical belt. Specifically, the first side connecting block 2451 connects the two first guide posts 244 together, which can improve the stability of the guide on the one hand and increase the strength enough to pull the first support plate 221 piled with the metal box bottom up and down on the other hand. At the same time, it can also be locked and connected to the vertical belt. Similarly, the second side connecting block 2471 connects the two second guide columns 246 together, which can improve the stability of the guide on the one hand, and on the other hand, it can increase the strength enough to pull the second support plate 231 stacked with the bottom of the metal box up and down, and at the same time, it can also be locked and connected with the vertical belt.

[0051] In one embodiment of the present invention, Figures 3-5 As shown, a first notch 2212 for avoiding the second guide column 246 is provided on one side of the first support plate 221 close to the second support plate 231, and a second notch 2312 for avoiding the first guide column 244 is provided on one side of the second support plate 231 close to the first support plate 221. The second notch 2312 and the first notch 2212 are arranged to be staggered with each other in an upper and lower manner, and the downward projection of the top connecting block 248 falls into the first notch 2212, and the other part falls into the second notch 2312. Specifically, the setting of the first notch 2212 provides space for avoiding the second guide column 246. Similarly, the setting of the second notch 2312 provides space for avoiding the first guide column 244. In this way, the first support plate 221 and the second support plate 231 can cooperate with each other through the notch, so that the first support plate 221 and the second support plate 231 will not be too far apart due to the first guide column 244 and the second guide column 246 being set in the middle. The piles on the first support plate 221 and the second support plate 231 can be as close as possible to facilitate switching of working areas.

[0052] In one embodiment of the present invention, Figure 3As shown, the metal box bottom stack loading device 20 also includes a travel switch 25, which includes a movable arm 251 and a trigger member 252. The movable arm 251 is installed on the bottom plate 21, and the trigger member 252 is installed on the first support plate 221 or the second support plate 231, and is used to contact or sense the movable arm 251 to limit the minimum descending stroke of the first support plate 221 or the second support plate 231. Specifically, when the first support plate 221 or the second support plate 231 descends to a set height position, the trigger member 252 thereon will trigger the movable arm 251 at the corresponding position, thereby giving a signal to the feed rack drive motor 241 of the feed rack lifting mechanism 24, causing it to stop controlling the first support plate 221 or the second support plate 231 to continue descending, thereby meeting the requirements of safe production.

[0053] In one embodiment of the present invention, Figures 4-5 As shown, the metal box bottom stacking and loading device 20 also includes a rack translation mechanism 26, which includes a movable slider 261, a fixed guide rail 262, and a rack driving cylinder 263. The movable slider 261 is connected and fixed to the bottom of the bottom plate 21, the fixed guide rail 262 slides with the movable slider 261 and is arranged horizontally, and the rack driving cylinder 263 is arranged horizontally below the bottom plate 21. The piston rod end of the rack driving cylinder 263 is connected and fixed to the bottom of the bottom plate 21 via a bottom connecting block 264. Specifically, the purpose of the rack translation mechanism 26 is to control the movement of the entire bottom plate 21 in a horizontal position, thereby controlling the movement position of the first support plate 221 and the second support plate 231, and switching between stacking and loading. Among them, when the piston rod top and bottom connecting block 264 of the material rack driving cylinder 263 moves forward and backward, it can drive the bottom plate 21 to move forward and backward, guided by the cooperation of the moving slider 261 and the fixed guide rail 262, so that the bottom plate 21 can be stably translated. Then, when the position of the first support plate 221 cooperates with the metal box bottom line linear feeding device 30 to complete the work, the material rack driving cylinder 263 drives the bottom plate 21 to move and move the second support plate 231 to a suitable position to cooperate with the metal box bottom line linear feeding device 30 to continue to complete the work. Such switching allows production to maintain continuity and high efficiency.

[0054] In one embodiment of the present invention, Figures 3-5 As shown, the metal box bottom pile loading device 20 further includes a base frame 27, which is disposed below the base plate 21, and the fixed guide rail 262 is fixedly mounted on the base frame 27. Specifically, the base frame 27 provides installation space for the rack drive cylinder 263 and the fixed guide rail 262, which supports the entire metal box bottom pile loading device 20 and facilitates the movement of the metal box bottom pile loading device 20 by moving the base frame 27.

[0055] In one embodiment of the present application, as shown in Figure 3 The first fixing holes 211 for fixing the first blocking columns 222 are arranged on the first stacking area of the bottom plate 21, and the second fixing holes 212 for fixing the second blocking columns 232 are arranged on the second stacking area of the bottom plate 21. Specifically, the number and position of the first fixing holes 211 are varied to fix the first blocking columns 222 at different positions, so that the first blocking columns 222 fixed at different positions enclose different areas to limit the stacking of different metal box bottoms. Similarly, the number and position of the second fixing holes 212 are varied to fix the second blocking columns 232 at different positions, so that the second blocking columns 232 fixed at different positions enclose different areas to limit the stacking of different metal box bottoms.

[0056] In one embodiment of the present application, as shown in Figures 6-8As shown, the metal box bottom linear feeding device 30 includes a frame 31, a suction cup 32, a suction cup bracket 33, a material picking and unloading lifting mechanism 34 and a material picking and unloading translation mechanism 35. The frame 31 is installed in the metal box bottom processing machine 10 and extends to the processing cavity 11. The material picking and unloading lifting mechanism 34 is installed on the frame 31. The material picking and unloading translation mechanism 35 includes a mounting seat 35a, a translation drive motor 35b, a driving gear 35c, a driven gear 35d, a rack 35e, a first pulley 35f, a second pulley 35g and a horizontal belt 35h. The mounting seat 35a is connected to the driving end of the material picking and unloading lifting mechanism 34 and is driven by the material picking and unloading lifting mechanism 34 to achieve rising and falling. The translation drive motor 35b is vertically installed on the mounting seat 35a. The driving gear 35c is It is horizontally arranged below the mounting seat 35a and connected to the main shaft of the translation drive motor 35b, the driven gear 35d is meshed with the driving gear 35c, the rack 35e is horizontally arranged and meshed with the driven gear 35d, the first pulley 35f and the second pulley 35g are respectively installed at the two ends of the length direction of the rack 35e, the horizontal belt 35h is wound and connected between the first pulley 35f and the second pulley 35g, the upper side of the horizontal belt 35h is locked and connected to the mounting seat 35a, the suction cup bracket 33 is locked and connected to the lower side of the horizontal belt 35h and extends back to the rack 35e, the suction cup 32 is installed on the suction cup bracket 33 and is used to adsorb the bottom of the metal box, and the suction cup 32 is located above the processing platform 12. Specifically, the material picking and placing lifting mechanism 34 can control the entire material picking and placing translation mechanism 35 to achieve lifting in the height direction through its driving end, thereby driving the suction cup 32 on the suction cup bracket 33 to achieve lifting in the height direction. The purpose is to control the metal box bottom sucked by the suction cup 32 to be placed on the processing platform 12 or picked up from the processing platform 12. The gear 35a is driven by the gear 35b to move back and forth, and the gear 35b is driven by the gear 35c to move back and forth, so that the bottom of the metal box can be picked up by the gear 35a.

[0057] More specifically, placing the metal box bottom sucked by the suction cup 32 on the processing platform 12 or picking it up from the processing platform 12 means picking up the metal box bottom from the first support plate 221 or the second support plate 231 to the processing table for processing, or picking up the processed metal box bottom from the processing platform 12 and placing it on the first support plate 221 or the second support plate 231. The first support plate 221 and the second support plate 231 can be switched in position, and the continuity of stacking and loading is ensured by switching the first support plate 221 and the second support plate 231.

[0058] In one embodiment of the present invention, Figure 6 and 8 As shown, the material loading and unloading translation mechanism 35 also includes an upper guide rail 35i, a lower guide rail 35j, an upper slider 35k, and a lower slider 351. The upper guide rail 35i and the lower guide rail 35j are respectively fixed to the top and bottom of the rack 35e. The upper slider 35k and the lower slider 351 slide together with the upper guide rail 35i and the lower guide rail 35j, respectively. The upper slider 35k is connected and fixed to the bottom of the mounting seat 35a, and the lower slider 35l is locked to the lower side of the horizontal belt 35h. Specifically, the upper guide rail 35i and the lower guide rail 35j reciprocate left and right along with the rack 35e, and the reciprocating motion is guided by the upper slider 35k fixed to the mounting seat 35a. At the same time, the lower slider 351 located below also moves left and right, and it and the lower side of the horizontal belt 35h move back and forth with half of the litigation follower rack 35e, so that the suction cup 32 can be driven to move back and forth.

[0059] In one embodiment of the present invention, Figures 6-8As shown, the suction cup bracket 33 includes a central connecting block 331, a long strip block 332, a first cantilever bar 333, and a second cantilever bar 334. The central connecting block 331 is locked and connected between the lower slider 351 and the lower side of the horizontal belt 35h. The long strip block 332 is horizontally fixed to the front side of the central connecting block 331. The first cantilever bar 333 and the second cantilever bar 334 are respectively arranged horizontally and vertically connected to the long strip block 332 near its two ends. The bottom of the first cantilever bar 333 and the second cantilever are both equipped with the suction cup 32. Specifically, the central connecting block 331 is provided to centrally connect the lower slider 351 and the lower side of the horizontal belt 35h, thereby connecting the lower side of the horizontal belt 35h and the lower slider 351 into a whole, so as to achieve left and right reciprocating movement with the rack 35e. In addition, the long strip block 332 is of sufficient length for the installation of the first cantilever bar 333 and the second cantilever bar 334, so that the first cantilever bar 333 and the second cantilever bar 334 can be spaced apart by a sufficient distance. In this way, when the position of the suction cup 32 installed on the first cantilever bar 333 corresponds to the processing platform 12, the position of the suction cup 32 installed on the second cantilever bar 334 can correspond to the first support plate 221 or the second support plate 231, thereby realizing the reciprocating transportation of loading or stacking materials and the processing position.

[0060] In one embodiment of the present invention, Figures 6-8 As shown, there are two upper sliders 35k and two lower sliders 351. The arrangement of two upper sliders 35k and two lower sliders 351 can improve the stability and reliability of the guide.

[0061] In one embodiment of the present invention, Figures 6-8 As shown, the material loading and unloading lifting mechanism 34 includes a lifting drive motor 341, a lifting plate 342, a screw 343, and a movable nut 344. The screw 343 is vertically and rotatably mounted on the frame 31. The lifting drive motor 341 is disposed at the top of the frame 31 and connected to the screw 343. The movable nut 344 is threadedly connected to the screw 343. The lifting plate 342 is fixedly connected to the movable nut 344 and extends outside the frame 31. The mounting seat 35a is fixedly connected to the side of the lifting plate 342. Specifically, the lifting drive motor 341 drives the screw 343 to rotate, converting the rotational force into controlling the up and down movement of the movable nut 344. This drives the lifting plate 342 up and down through the movable nut 344, which in turn drives the mounting seat 35a up and down through the lifting plate 342. In this way, the up and down movement of the entire material loading and unloading translation mechanism 35 is controlled.
