Description
Technical Field
[0001] This invention relates to the technical field of stamping parts processing, specifically to an automatic stacking mechanism for loading and unloading industrial robots. Background Technology
[0002] Mobile phone back panel stamping technology, as a core component of precision manufacturing, is developed in close alignment with material innovation (such as fiberglass boards, metal alloys, and composite materials), process upgrades (high-pressure forming, CNC precision carving), and market demands in the 5G era. Through the coordinated operation of customized vacuum suction cup arrays and robotic arms, fully automated loading, unloading, and stacking of stamped parts can be achieved, thereby improving yield rates, reducing labor costs, and accelerating the industry's evolution towards intelligence and efficiency.
[0003] Traditional stamping equipment, with its fixed molds and transfer structure, is inadequate for meeting the production needs of stamped parts with different specifications. When product models need to be changed, it is often necessary to readjust the movement path of the robotic arm or replace the clamping tools. This not only increases the complexity of production line changeover but also significantly prolongs the changeover time, making it difficult to meet the flexible needs of multi-variety, small-batch production.

[0037] (III) Beneficial Effects
[0038] Compared with the prior art, the present invention provides an automatic stacking mechanism for loading and unloading industrial robots, which has the following beneficial effects:
[0039] 1. This industrial robotic arm-based automatic stacking mechanism automates the material handling process. The robotic arm picks up blanks from the blank placement area in a predetermined sequence, processes them sequentially through multiple stamping machines, and finally places the finished products in an orderly manner into the finished product placement area. This achieves automation and continuity of the production process, significantly improving production efficiency. Furthermore, the precise coordination between the automatic stacking structure and the robotic arm effectively reduces the error rate and failure rate during operation, minimizing production interruptions and losses caused by human factors or mechanical malfunctions, thereby improving overall production quality and stability.
[0040] 2. This industrial robot's automatic stacking mechanism for loading and unloading materials allows for precise docking with the moving or rotating components by pressing or pulling the shaft three during blank model changes. Rotating the shaft three then adjusts the lateral and longitudinal movement range of the vacuum suction cup two. This design effectively avoids situations where operators need to control a specific range individually, significantly reducing operational difficulty.
[0041] 3. This industrial robot's automatic loading and unloading stacking mechanism places the blanks to be processed onto a transfer platform. Adjustment components on the platform align the blanks, and fixed baffles on both sides of the platform form an adjustable limiting structure. Combined with the linkage mechanism between the bottom slider and screw, this ensures precise positioning of blanks of different specifications. This dynamic adjustment method not only eliminates the cumbersome steps of changing fixtures in traditional equipment but also reduces production line changeover time to one-third of the original mode, significantly improving the flexibility of multi-variety mixed-line production.
[0042] 4. This industrial robot's automatic stacking mechanism for loading and unloading materials achieves automated drive of the adjustment components through the coordinated design of the transmission and lifting components and the torque conversion via gear sets and commutators. When the screw five of the lifting component rotates, it drives the gear three to rotate synchronously. After two-stage speed change via the gear four of the transmission component, the telescopic tube, and the commutator, it is finally converted into the linear reciprocating motion of the baffle two. This mechanical energy transmission method ensures the power synchronization between the transfer platform and the stacking mechanism, maintaining a high degree of consistency in the vertical lifting and horizontal positioning of the billet, effectively avoiding material deviation caused by uncoordinated movements.
[0043] 5. This industrial robot's automatic stacking mechanism for loading and unloading materials utilizes a four-bar positioning structure with limit components. Through the coordinated adjustment of sliders three and four on guide rails one and two, it can quickly adapt to the boundary constraints of blanks of different sizes. In particular, the double-threaded design of screws three and four allows the operator to simultaneously adjust the spacing between the limit bars on both sides simply by rotating the adjustment handle, doubling the efficiency compared to the traditional single-sided adjustment mode.

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0064] As attached Figure 1 , 8 As shown in Figure 9, an embodiment of the present invention provides an automatic stacking mechanism for loading and unloading industrial robots, including a robotic arm 600, an adsorption component 2 700 connected to the robotic arm 600, a platform 100 disposed on one side of the robotic arm 600, a transfer platform 110 disposed on the top of the platform 100, and an adjustment component 200, as well as an adsorption component 300 disposed on the adjustment component 200.
[0065] Specifically, the robotic arm 600, in conjunction with the adsorption component 700, can precisely and efficiently complete the gripping and placement of materials, greatly improving the efficiency of loading and unloading. The adsorption component 300, mounted on the adjustment component 200, can flexibly adjust its adsorption position and angle according to the size, shape, and stacking requirements of different materials, ensuring stable and reliable adsorption for various materials. This effectively prevents materials from slipping during handling, improving the accuracy and stability of stacking. Simultaneously, the platform 100 and transfer station 110 provide convenient space for temporary storage and transfer of materials, making the entire loading, unloading, and stacking process smoother and more orderly, reducing waiting time in production, and further improving overall production efficiency. Moreover, this automated stacking mechanism reduces manual operation, lowers labor costs, and avoids errors and safety hazards that may arise from manual operation, improving production safety and reliability.
[0066] The second adsorption component 700 includes: a box 710, which is mounted on the robotic arm 600, and a rotating shaft 720 is rotatably connected to the box 710; a slider 750, which slides inside the box 710, and a rotating component and a moving component are provided inside the slider 750, which are connected to the rotating shaft 720; and a bracket 770, which is rotatably connected to the slider 750, and a vacuum suction cup 780 is provided on the bracket 770. Pressing or pulling the rotating shaft 720 causes the rotating shaft 720 to engage with the rotating component or the moving component. Rotating the rotating shaft 720 drives the rotating component or the moving component, causing the bracket 770 to rotate on the slider 750 or the slider 750 to move inside the box 710, thereby changing the adsorption range of the vacuum suction cup 780.
[0067] Specifically, firstly, by pressing or pulling the rotating shaft 720 and rotating it, the adsorption range of the vacuum suction cup 780 can be flexibly and precisely changed. This allows it to adapt to the material gripping needs of different sizes, shapes, and positions, greatly enhancing the adaptability and versatility of the robotic arm 600 in loading, unloading, and stacking processes. Secondly, after flexibly adjusting the adsorption range, the vacuum suction cup 780 can more stably and reliably adsorb materials, effectively reducing the risk of material shaking and falling during handling, further improving the quality and efficiency of stacking, and also reducing the probability of equipment damage and safety accidents that may be caused by material slippage.
[0068] As attached Figure 8 and 9 As shown, in some embodiments, the rotating assembly includes:
[0069] Worm gear 3 751 is provided on the outer wall of shaft 3 720. Worm wheel 3 752 and gear 2 753 are rotatably connected to the inner wall of slider 5 750. Worm wheel 3 752 and gear 2 753 are connected by a shaft. Worm wheel 3 752 is meshed with worm gear 3 751. One end of the shaft is connected to bracket 770.
[0070] Specifically, through the meshing connection of worm gear 3 751 and worm wheel 3 752, a precise transmission ratio can be achieved, allowing the rotation of shaft 3 720 to be accurately converted into the rotation of bracket 770. This enables more precise control of the position and angle of vacuum suction cup 2 780, further improving the gripping accuracy of different materials. On the other hand...
[0071] As attached Figure 8 and 9As shown, in some embodiments, the moving component includes: a second worm gear 730, which is rotatably connected to a fifth slider 750; a second worm wheel 740, which is disposed on one side of the fifth slider 750 and meshes with the second worm gear 730; a second rack 760, which is disposed on the inner bottom surface of the housing 710 and meshes with the second worm wheel 740; and a third rotating shaft 720, whose outer side wall is provided with two protrusions, which engage with the third worm gear 751 or the second worm gear 730 when the third rotating shaft 720 is pulled or pressed.
[0072] Specifically, when worm gear 2 730 rotates, it drives worm wheel 2 740, which in turn meshes with rack 2 760, causing slider 5 750 to move along the direction of rack 2 760, thus achieving precise horizontal movement of vacuum suction cup 2 780. The two protrusions on the outer wall of rotating shaft 3 720 engage with worm gear 3 751 or worm gear 2 730 when rotating shaft 3 720 is pulled or pressed. This design allows operators to easily and quickly adjust the position and state of vacuum suction cup 2 780 according to actual work needs, improving the operational flexibility and work efficiency of the entire stacking mechanism.
[0073] As attached Figure 2-4 As shown, in some embodiments, an adjustment assembly 400 is provided on the top of the transfer platform 110. The adjustment assembly 400 includes: a first baffle 410, which is disposed on the top of the transfer platform 110. A through groove 111 is provided on the top of the transfer platform 110. A second baffle 420 is provided on the top of the transfer platform 110; a first slider 430, which slides on the through groove 111 and is connected to the second baffle 420; a first rotating shaft 460, which is rotatably connected to the transfer platform 110. A first bearing seat 440 is provided on the top of the first rotating shaft 460. A first screw 450 is threadedly connected to the first bearing seat 440. One end of the first screw 450 is rotatably connected to the second baffle 420.
[0074] Specifically, when the position of baffle 420 needs to be adjusted, the operator only needs to rotate screw 450. Since screw 450 is threadedly connected to bearing housing 440 and one end is rotatably connected to baffle 420, the rotation of screw 450 will drive baffle 420 to move along the through groove 111, thereby causing the connected slider 430 to slide on the through groove 111. This design allows the position of baffle 420 to be flexibly adjusted according to actual working needs to meet the requirements of different sized blanks. At the same time, the baffle 410 also plays a role in assisting positioning and limiting the range of material movement, further improving the accuracy and stability of stacking.
[0075] The top of the transfer platform 110 is equipped with two fixed baffles 410 and two movable baffles 420 to restrict the movement of the billet. This arrangement effectively prevents the billet from shifting or slipping during stacking, ensuring the stability and safety of the stacking process. Furthermore, the movable nature of the baffles 420 allows the mechanism to accommodate billets of different sizes, greatly improving its versatility and flexibility.
[0076] As attached Figure 2-5 As shown, in some embodiments, a limiting component 500 is provided at the bottom of the platform 100. The limiting component 500 includes: a first limiting rod 540, which is disposed at the top of the platform 100; and a second limiting rod 580, which is disposed at the top of the platform 100. At least four limiting rods 540 and 580 are provided, which are respectively disposed on the outer side wall of the billet to limit the position of the billet.
[0077] Specifically, when the billet is placed on the transfer table 110, the first limiting rod 540 and the second limiting rod 580 can effectively restrict its position from four outer directions. This restriction method can prevent the billet from shifting due to external forces during the stacking process, ensuring that the billet is always in the predetermined stacking position.
[0078] The limiting assembly 500 also includes: a guide rail 510, which is located on the top of the platform 100, and a slider 520 is slidably connected to the guide rail 510; a screw 530, which is threadedly connected to the inner wall of the slider 520 and has one end abutting against the outer wall of the guide rail 510; and a guide rail 560, which is located on the top of the platform 100, and a slider 570 is slidably connected to the guide rail 560, and a screw 550 is rotatably connected inside the guide rail 560, with the screw 550 threadedly connected to the slider 570.
[0079] Specifically, through the sliding connection between guide rail 1 510 and slider 3 520, and the threaded contact design of screw 3 530, the lateral position of limit rod 1 540 on the platform 100 can be precisely adjusted; similarly, the sliding engagement between guide rail 2 560 and slider 4 570, and the adjustment function of the positive and negative threads of screw 4 550, can precisely control the longitudinal position of limit rod 2 580. This structure allows the limit component 500 to be flexibly adjusted according to blanks of different sizes, further improving the adaptability of the stacking mechanism to blanks of different specifications and the stacking accuracy.
[0080] As attached Figure 2-5As shown, in some embodiments, a lifting assembly 800 is provided on the platform 100 inside the limiting assembly 500. The lifting assembly 800 includes: a support frame 840, which is fixed inside the platform 100. A threaded sleeve 860 is rotatably connected to the support frame 840. A screw 830 is threadedly connected to the inner wall of the threaded sleeve 860. A support plate 810 is provided on the top of the screw 830. A gear 910 is provided on the outer wall of the threaded sleeve 860; a slide rod 820, which is located at the bottom of the support plate 810 and is slidably connected to the support frame 840; and a motor 850, which is located at the bottom of the support frame 840. The output shaft of the motor 850 is provided with a gear that engages with the gear 910.
[0081] Specifically, after the motor 850 starts, its output shaft drives the gear to rotate. Since this gear cooperates with gear three 910, it drives the threaded sleeve 860 to rotate on the support frame 840. As the threaded sleeve 860 rotates, the screw five 830, threaded to its inner wall, moves up or down, thereby driving the support plate 810 to rise and fall synchronously. During this process, the slide rod 820 slides at the bottom of the support plate 810 and is connected to the support frame 840, providing stable guidance for the lifting and lowering of the support plate 810 and ensuring smooth lifting. This design allows the lifting assembly 800 to precisely adjust the height of the support plate 810 according to actual needs. A photoelectric sensor is installed on the outer wall of the limit rod one 540 or the limit rod two 580. This photoelectric sensor is used to detect whether there is a blank at that position and, in conjunction with the adjustment assembly 400, the adjustment assembly 400 promptly adsorbs and transfers the blank. This photoelectric sensor is not shown in the attached drawings.
[0082] As attached Figure 4As shown, in some embodiments, a transmission assembly 900 is provided inside the platform 100. The transmission assembly 900 is connected to the adjustment assembly 400 and the lifting assembly 800 respectively. When the screw 830 is working, the torque is transmitted to the adjustment assembly 400 through the transmission assembly 900, which drives the baffle 420 to reciprocate. The transmission assembly 900 includes: a fourth gear 920, rotatably connected to the bottom of the support frame 840, with a telescopic tube 930 mounted on the fourth gear 920; a second commutator 940, located inside the platform 100, with its input and output connected to the telescopic tube 930, and its output shaft connected to a fourth rotating shaft 950; a second bearing seat 470 located on the inner bottom surface of the platform 100, with two second sliders 490 mounted on the second bearing seat 470, connected to a first rotating shaft 460; a second rotating shaft 480 rotatably connected to the second bearing seat 470; and a first commutator 491 located on the top of the second bearing seat 470, with its input and output connected to the first commutator 491. The output shaft is connected to a rotating shaft 480, one of which is connected to a rotating shaft 950, and the other is threaded to a slider 490. A frame 250 is provided on one side of the adsorption component 300. A baffle 240 is rotatably connected to the frame 250 and a worm gear 252 is provided on it. A worm 251 is rotatably connected inside the frame 250 and meshes with the worm gear 252. A gear 253 is provided on the outer wall of the worm 251. A through groove is provided on the frame 250. A rack 260 is provided on the top of the platform 100. A toothed structure is provided on one side of the rack 260 near the top.
[0083] The adjustment component 200 includes a track 210, which is located on the top of the platform 100. A slide block 220 is slidably connected to the track 210. The slide block 220 is driven by a drive device, which can be a belt-driven gantry. The drive device is not shown in the attached drawings and belongs to the prior art. A cylinder 230 is fixed on the slide block 220. A connecting plate 310 is provided on the output shaft of the cylinder 230. A vacuum suction cup 320 is provided at the bottom end of the connecting plate 310.
[0084] Specifically, when screw 5 830 starts, the torque it generates is first transmitted to gear 4 920. Gear 4 920 then transmits power to commutator 2 940 via telescopic tube 930. Rotation is restricted between the two rods in telescopic tube 930 by a convex strip. After commutator 2 940 adjusts the power direction, it is transmitted to commutator 1 491 via shaft 4 950. Commutator 1 491 further distributes the power to two shafts 2 480. Shaft 2 480 drives slider 2 490 to reciprocate linearly on bearing seat 2 470, thereby driving baffle 2 420 in adjustment assembly 400 to move synchronously, achieving precise adjustment of the material position. The slide block 220 moves to drive the lateral position of the vacuum suction cup 320, and the cylinder 230 changes the longitudinal position, so as to facilitate the transfer of the blank on the lifting assembly 800 to the adjusting assembly 400. The adjusted blank is then moved into the stamping machine by the adsorption assembly 700 on the robotic arm 600.
[0085] When the blanks on the lifting assembly 800 are exhausted, the blanks can be pre-stacked into the frame 250, and the frame 250 can be installed into the connecting plate 310. The frame 250 containing the blanks is moved above the lifting assembly 800 by the movement of the slide 220 on the track 210. At this time, the support plate 810 is at its highest point, and the control cylinder 230 is activated, causing the frame 250 to descend. The rack 260 then moves into the groove of the frame 250 and meshes with the gear 253. The gear 253 drives the worm gear 251 to rotate, which in turn drives the worm wheel 252 to rotate, thereby pushing the stop bar 240 to rotate to a vertical position. In this state, the blanks inside the frame 250 are unloaded onto the support plate 810 under gravity. After the stop bar 240 opens, the frame 250 and the support plate 810 descend synchronously. After the support plate 810 is lowered to its lowest point, the frame 250 is raised by controlling the cylinder 230. The rack 260 and gear 253 then mesh again, causing the stop bar 240 to return to a vertical position. The self-locking function of the worm gear ensures that the stop bar 240 is maintained at a certain angle.
[0086] Working principle:
[0087] First, the motor 850 is started. The output shaft of the motor 850 drives the gear to rotate, which in turn drives the mating gear three 910 to rotate, thereby causing the threaded sleeve 860 to rotate on the support frame 840. The rotation of the threaded sleeve 860 causes the screw five 830 to rise or fall, and the support plate 810 at the top of the screw five 830 rises or falls accordingly. The slide rod 820 is slidably connected to the support frame 840 at the bottom of the support plate 810, providing stable guidance for the rise and fall of the support plate 810 and ensuring smooth lifting. At the same time, the limiting rod one 540 and the limiting rod two 580 restrict the position of the billet from the four outer directions, preventing it from shifting due to external forces during stacking. The photoelectric sensor (not shown in the attached figure) detects whether there is billet at the outer wall position of the limiting rod one 540 or the limiting rod two 580. If there is billet, the adjusting component 400 promptly adsorbs and transfers the billet.
[0088] Secondly, when screw 830 starts, the generated torque is transmitted to gear 920. Gear 920 transmits power to commutator 940 via telescopic tube 930. Commutator 940 adjusts the direction of power and transmits it to commutator 491 via shaft 950. Commutator 491 distributes power to two shafts 480. Shaft 480 drives slider 490 to reciprocate linearly on bearing seat 470. Simultaneously, slider 490 drives shaft 460 to move linearly, which in turn moves baffle 420 on bearing seat 440, thereby achieving precise adjustment of the material position. The robotic arm 600 picks up the adjusted blank and processes it sequentially through multiple stamping machines. Finally, the finished product is placed in an orderly manner in the finished product placement area, realizing the automation and continuity of the production process.
[0089] Finally, when the blanks on the lifting assembly 800 are used up, the blanks are pre-stacked into the frame 250 and the frame 250 is installed into the connecting plate 310. By moving the slide 220 on the track 210, the frame 250 containing the blank is moved above the lifting assembly 800. At this time, the support plate 810 is at its highest point. The control cylinder 230 is activated, driving the frame 250 to descend. The rack 260 moves into the groove of the frame 250 and meshes with the gear 253. The gear 253 drives the worm gear 251 to rotate, which in turn drives the worm wheel 252 to rotate, pushing the stop bar 240 to rotate to a vertical position. The blank in the frame 250 is unloaded onto the support plate 810 under the action of gravity. After the stop bar 240 is opened, the frame 250 and the support plate 810 descend synchronously. When the support plate 810 reaches its lowest point, the control cylinder 230 lifts the frame 250. The meshing of the rack 260 and the gear 253 again resets the stop bar 240 to a vertical position. With the help of the self-locking function of the worm wheel and worm, the stop bar 240 is kept at a certain angle.
