Description

Technical Field

[0001] This utility model belongs to the field of refrigerator liner molding technology, and specifically relates to a double feeding suction cup assembly for the feeding station of a refrigerator liner molding machine. Background Technology

[0002] Currently, the semi-finished refrigerator liner at the unloading station of the refrigerator liner forming machine is in an upside-down state. It needs to be transferred to the press at the next station for punching to form the finished refrigerator liner. Then, the finished refrigerator liner is transferred to the conveyor belt for transport to the next process.

[0003] In existing technologies, a translational robot is typically used in conjunction with a single suction cup assembly to adsorb and transfer semi-finished or finished refrigerator liners. However, using a translational robot means that the finished refrigerator liner can only be adsorbed and removed from the press and placed on the conveyor belt before it can return to the unloading station to adsorb and move the semi-finished refrigerator liner to the press for punching operations. This means that the material handling operations at the press station cannot be carried out continuously, increasing time costs and affecting production progress. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a double-feeding suction cup assembly for the unloading station of a box liner forming machine. The specific technical solution is as follows:

[0005] This utility model provides a double unloading suction cup assembly for the unloading station of a box liner forming machine, including a multi-axis robotic arm. The end face of the multi-axis robotic arm is vertically connected to a mounting plate, and unloading suction cup assemblies are symmetrically arranged on both sides of the mounting plate.

[0006] The feeding suction cup assembly includes a horizontally arranged first connecting plate, with horizontal support rods symmetrically mounted on the bottom surfaces of both ends of the first connecting plate. The end faces of the two horizontal support rods on the same side are perpendicularly connected to the corresponding side of the mounting plate. A second connecting plate is symmetrically connected horizontally and vertically between the bottom surfaces of the two horizontal support rods, and a material support assembly is provided on the bottom surface of the second connecting plate.

[0007] The support assembly includes two longitudinal support rods that intersect the two transverse support rods perpendicularly in space, and the longitudinal support rods are slidably suspended from the bottom surface of the corresponding second connecting plate along the long side of the transverse support rods; two cylinders are arranged laterally opposite to each other on the top surface of the second connecting plate, and the piston rod of each cylinder is drivenly connected to the longitudinal support rod corresponding to it in the same direction; multiple vertical rods are vertically connected at equal intervals along the long side of the bottom surface of the longitudinal support rods, and pneumatic suction cups are arranged vertically at the lower part of the vertical rods along the extension direction of the piston rod of the corresponding cylinder.

[0008] As a preferred technical solution of this utility model, the piston rod end face of the cylinder is vertically connected to a linkage block, and the bottom end of the linkage block is vertically connected to the top surface of the corresponding longitudinal support rod; the bottom surface of the end of the second connecting plate is symmetrically mounted with linear slide rails along the long side of the corresponding transverse support rod, and two sliders are laterally sliding and engaging on the linear slide rails, and the bottom surface of each slider is vertically connected to the top surface of the corresponding longitudinal support rod.

[0009] As a preferred embodiment of this utility model, the pneumatic suction cup on the inner side of the material support assembly is higher than the pneumatic suction cup on its outer side.

[0010] As a preferred technical solution of this utility model, the lower part of the vertical rod has a long strip hole through it, and the inner end of the pneumatic suction cup is axially connected to an air support tube. The tail of the air support tube passes through the long strip hole corresponding to the vertical rod and is clamped and fixed by positioning nuts screwed on both sides of the long strip hole.

[0011] In a preferred embodiment of this invention, both the horizontal and vertical struts are made of industrial aluminum profiles.

[0012] As a preferred embodiment of this utility model, the multi-axis robotic arm adopts a six-axis design.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, two independent unloading suction cup assemblies are symmetrically arranged on both sides of the mounting plate. This allows the multi-axis robotic arm to simultaneously carry a semi-finished product to be placed into the press and a finished product just removed from the press. When the multi-axis robotic arm moves to the press station, it does not need to first remove the finished product and place it back on the conveyor belt, and then return to retrieve the semi-finished product and place it into the press, as is required by existing translational robotic arms. Instead, it can directly use the idle unloading suction cup assembly to remove the finished product from the press, then rotate 180° in place to place the semi-finished product it is carrying into the press, and then move the finished product onto the conveyor belt. This eliminates the idle waiting time in the existing technology's cycle of "retrieving the finished product from the press → placing it on the conveyor belt → returning to retrieve the semi-finished product → placing it into the press," enabling continuous and efficient unloading and retrieval operations of the press, thus improving production progress.

[0015] 2. In this invention, the multi-axis robotic arm can flip the two suction cup assemblies, allowing the supporting assembly to penetrate deep into the refrigerator liner. A cylinder drives the corresponding longitudinal support rod to slide outwards, causing the pneumatic suction cup at the end of the vertical rod to contact the inner wall of the refrigerator liner. This utilizes both the suction force of the pneumatic suction cup and the opposing supporting force of the supporting assembly on both sides, significantly enhancing the suction force. This strong suction force enables the multi-axis robotic arm to reliably move the finished product above the waste collection box for shaking off waste, effectively removing residual waste from drilling and improving the cleanliness and quality of the finished product.

[0016] 3. In this invention, each suction cup assembly includes two support components, and the position of the longitudinal support rods can be adjusted by a cylinder. For a single-compartment refrigerator liner, the outermost longitudinal support rods on the two support components can be adjusted so that the corresponding two sets of suction cups jointly adhere and support the inner end wall of a single refrigerator liner space, providing a more balanced support force. For a double-compartment refrigerator liner, the two support components can be inserted into the corresponding compartments, and then the two longitudinal support rods on the same support component can be adjusted so that the four sets of suction cups respectively adhere and support the inner end walls of two independent compartments in pairs. This adjustable dual support component design allows the same suction cup device to flexibly adapt to refrigerator liners with different internal compartment structures, greatly improving the versatility of the equipment and the flexibility of the production line.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0023] Example

[0024] To address the technical problems in the background section, the following dual-feeding suction cup assembly for the unloading station of a box liner forming machine is provided:

[0025] Combination Figures 1-3As shown, a double-feeding suction cup assembly for the unloading station of a box liner forming machine includes a multi-axis robotic arm 1. The end face of the multi-axis robotic arm 1 is vertically connected to a mounting plate 11, and unloading suction cup assemblies 2 are symmetrically arranged on both sides of the mounting plate 11.

[0026] The feeding suction cup assembly 2 includes a horizontally arranged first connecting plate 21. Horizontal support rods 22 are symmetrically mounted on the bottom surfaces of both ends of the first connecting plate 21. The end faces of the two horizontal support rods 22 on the same side are perpendicularly connected to the corresponding side of the mounting plate 11. A second connecting plate 23 is symmetrically connected horizontally and vertically between the bottom surfaces of the two horizontal support rods 22. A material support assembly 24 is provided on the bottom surface of the second connecting plate 23.

[0027] The support assembly 24 includes two longitudinal support rods 241 that are perpendicular to both horizontal support rods 22 in space, and the longitudinal support rods 241 are slidably suspended with the bottom surface of the corresponding second connecting plate 23 along the long side of the horizontal support rods 22; the top surface of the second connecting plate 23 is provided with two cylinders 25 arranged laterally opposite to each other, and the piston rod of each cylinder 25 is drivenly connected to the longitudinal support rod 241 in the same direction; the bottom surface of the longitudinal support rod 241 is vertically connected with multiple vertical rods 242 at equal intervals along its long side, and the lower part of the vertical rod 242 is provided with a pneumatic suction cup 243 vertically along the extension direction of the piston rod of the corresponding cylinder 25.

[0028] like Figure 2 and Figure 3 As shown, preferably, both the horizontal support rod 22 and the vertical support rod 241 are made of industrial aluminum profiles.

[0029] like Figure 1 As shown, preferably, the multi-axis robotic arm 1 adopts a six-axis design.

[0030] In the above technical solution, two independent feeding suction cup assemblies 2 are symmetrically arranged on both sides of the mounting plate 11 in the dual feeding suction cup assembly. This allows the multi-axis robotic arm 1 to simultaneously carry a semi-finished product to be placed into the press and a finished product just removed from the press. When the multi-axis robotic arm 1 moves to the press station, it does not need to first remove the finished product and place it back on the conveyor belt, then return to retrieve the semi-finished product and place it into the press, as is required by existing translational robotic arms. Instead, it can directly use the idle feeding suction cup assembly 2 to remove the finished product from the press, then rotate 180° in place to place the semi-finished product it is carrying into the press, and then move the finished product onto the conveyor belt. This eliminates the idle waiting time in the existing technology's cycle of "retrieving finished product from press → placing it on conveyor belt → returning to retrieve semi-finished product → placing it into press," enabling continuous and efficient feeding and retrieval operations of the press, thus improving production progress.

[0031] In this dual-feeding suction cup assembly, the multi-axis robotic arm 1 can flip the two feeding suction cup assemblies 2, allowing the supporting assembly 24 to penetrate deep into the refrigerator liner. The cylinder 25 drives the corresponding longitudinal support rod 241 to slide outward, causing the pneumatic suction cup 243 at the end of the vertical rod 242 to contact the inner wall of the refrigerator liner. This utilizes both the suction force of the pneumatic suction cup 243 and the opposing supporting force of the supporting assembly 24 to both sides, significantly enhancing the suction force. The strong suction force enables the multi-axis robotic arm 1 to reliably move the finished product above the waste collection box for shaking off the waste, effectively removing residual waste from drilling and improving the cleanliness and quality of the finished product.

[0032] Each suction cup assembly 2 in this dual-feeding suction cup system includes two supporting components 24, and the position of the longitudinal support rods 241 can be adjusted by a cylinder 25. For a single-compartment refrigerator liner, the outermost longitudinal support rods 241 on the two supporting components 24 can be adjusted so that the corresponding two sets of suction cups 243 jointly adhere and support the inner end wall of a single refrigerator liner space, providing more balanced support. For a double-compartment refrigerator liner, the two supporting components 24 can be inserted into the corresponding compartments, and then the two longitudinal support rods 241 on the same supporting component 24 can be adjusted so that the four sets of suction cups 243 respectively adhere and support the inner end walls of two independent compartments in pairs. This adjustable dual-support component design allows the same suction cup device to flexibly adapt to refrigerator liners with different internal compartment structures (single / double compartment), greatly improving the versatility of the equipment and the flexibility of the production line.

[0033] This dual-feed suction cup assembly uses industrial aluminum profiles as the horizontal support rods 22 and the vertical support rods 241. Utilizing the advantages of industrial aluminum profiles—lightweight, high strength, good rigidity, and ease of processing and connection—it ensures the structural stability of the entire dual-feed suction cup assembly frame, enabling it to withstand the weight of the refrigerator liner and the inertial forces during vibration operation. At the same time, the standardized profiles facilitate the manufacturing, assembly, and maintenance of the assembly.

[0034] In this dual-feeding suction cup assembly, the multi-axis robotic arm 1 is preferably designed as a six-axis robot. Because the six-axis robotic arm provides extremely high degrees of freedom, it can realize complex spatial trajectory movements (such as accurately reaching the feeding station and the inside of the press, performing 180° rotation, and performing specific shaking actions to shake off waste materials) as well as precise attitude control (such as flipping the suction cup assembly into the inner liner and ensuring that the suction cup is facing the adsorption surface). This is the basic guarantee for realizing the above-mentioned continuous operation, internal adsorption and waste shaking functions.

[0035] This dual-feed suction cup assembly solves the bottleneck of continuous material handling at the press station by employing a symmetrical dual-feed suction cup design, achieving seamless connection between processes and significantly improving production progress. Simultaneously, the adjustable support assembly 24, the internal suction method, and the flexibility of the multi-axis robotic arm 1 significantly enhance suction stability, unlock the crucial "waste removal" function to improve quality, and improve adaptability to inner liner sizes.

[0036] like Figure 2 and Figure 3 As shown, the piston rod end face of the cylinder 25 is vertically connected to a linkage block 251, and the bottom end of the linkage block 251 is vertically connected to the top surface of the corresponding longitudinal support rod 241; the bottom surface of the end of the second connecting plate 23 is symmetrically mounted with linear slide rails 252 along the long side of the corresponding transverse support rod 22, and two sliders 253 are laterally slidably engaged on the linear slide rail 252, and the bottom surface of each slider 253 is vertically connected to the top surface of the corresponding longitudinal support rod 241.

[0037] In the above technical solution, the linear guide rail 252 and the slider 253 constitute a linear guiding system. When the piston rod of the cylinder 25 extends or retracts, it drives the longitudinal support rod 241 to move through the linkage block 251. This guiding system constrains the movement trajectory of the longitudinal support rod 241, so that it can only slide along the long side of the transverse support rod 22, avoiding possible deviation, shaking or jamming during the movement.

[0038] like Figures 2-4 As shown, the pneumatic suction cup 243 inside the material support assembly 24 is higher than the pneumatic suction cup 243 outside it.

[0039] like Figure 4 As shown, the lower part of the vertical rod 242 has a vertically penetrating elongated hole 2421, and the inner end of the pneumatic suction cup 243 is axially connected to an air support tube 2431. The tail of the air support tube 2431 passes through the elongated hole 2421 corresponding to the vertical rod 242, and is clamped and fixed by positioning nuts 2432 screwed on both sides of the elongated hole 2421.

[0040] In the above technical solution, the elongated hole 2421 provides vertical adjustment stroke. After loosening the positioning nut 2432, the air support tube 2431 can be slid up and down along the elongated hole 2421, thereby adjusting the installation height of the pneumatic suction cup 243 relative to the vertical rod 242. This design allows the height of each pneumatic suction cup 243 to be adjusted independently, providing a structural basis for meeting the staggered layout requirement of "inner suction cup higher than outer suction cup".

[0041] The pneumatic suction cup 243 inside the support assembly 24 is designed to be higher than the pneumatic suction cup 243 outside. For the inner liner of a double-compartment refrigerator, this stepped adsorption layout makes the adsorption force generated by the pneumatic suction cup 243 form a spatial support effect, which significantly enhances the overall gripping stability and balance of the inner liner of the double-compartment refrigerator and effectively prevents the inner liner from shaking or falling off during transportation or shaking off waste materials.

[0042] Working principle and usage process of this utility model:

[0043] The use of this utility model involves the following steps:

[0044] 1. Initial state preparation

[0045] The multi-axis robotic arm 1 moves two symmetrically installed unloading suction cup assemblies 2 to the unloading station. The cylinder 25 drives the piston rod to retract, which pulls the longitudinal support rod 241 along the linear slide rail 252 to slide inward through the linkage block 251, so that the support assembly 24 is in a retracted state to adapt to the space inside the refrigerator.

[0046] 2. Semi-finished product handling and transfer

[0047] The multi-axis robotic arm 1 flips over, allowing the support assembly 24 to extend into the inverted refrigerator liner semi-finished product. The cylinder 25 pushes the longitudinal support rod 241 to slide outward along the linear slide rail 252. Multiple pneumatic suction cups 243 at the bottom of the longitudinal support rod 241 contact the inner end wall of the liner. After the pneumatic suction cups 243 adsorb the material, the multi-axis robotic arm 1 lifts the semi-finished product and moves it to the press to wait.

[0048] 3. Continuous material handling and rotation operation

[0049] The multi-axis robotic arm 1 uses its idle feeding suction cup assembly 2 to pick up the pre-punched finished product from the press; similarly, the cylinder 25 unfolds the supporting assembly 24, and the pneumatic suction cup 243 picks up the inner end wall of the finished product. The multi-axis robotic arm 1 rotates 180°, and the feeding suction cup assembly 2 carrying the semi-finished product turns towards the press, placing the semi-finished product into the press for punching; the feeding suction cup assembly 2 carrying the finished product synchronously turns towards the conveyor belt direction.

[0050] 4. Finished product waste removal and unloading

[0051] The multi-axis robotic arm 1 moves the finished product to the top of the waste collection box. Utilizing the flexibility of the multi-axis robotic arm 1, it performs a shaking action. After shaking is completed, the multi-axis robotic arm 1 transfers the finished product to the conveyor belt. The cylinder 25 retracts the longitudinal support rod 241, and the pneumatic suction cup 243 releases the suction, allowing the finished product to fall onto the conveyor belt.

[0052] 5. Reset and Cycling

[0053] The multi-axis robotic arm 1 returns to the unloading station and repeats the above steps, carrying the new semi-finished product and the next finished product at the same time, realizing continuous operation of material picking and unloading at the press station.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
