Description

Technical Field

[0001] This utility model belongs to the technical field of feeding mechanisms, specifically relating to a feeding mechanism for a pearl punching machine. Background Technology

[0002] In pearl drilling machines, the suction cup structure of the feeding mechanism is crucial. Previously, manual feeding was inefficient and prone to damaging the pearls. The suction cup structure was developed to automate the feeding process. It utilizes negative pressure, with the suction cups adhering tightly to the pearl's surface to hold it in place. This method allows for precise pearl gripping and flexible adjustment of suction force based on factors such as pearl size. Furthermore, compared to traditional methods, it significantly increases feeding speed and reduces the likelihood of pearl damage during handling, thereby improving the overall efficiency of pearl drilling.

[0003] Traditional pearl feeding mechanisms are typically designed for pearls of specific shapes and sizes. To handle pearls of different shapes, frequent changes of specialized clamps are required. This is not only cumbersome but also costly. A new structure is needed that can pick up and hold pearls of various shapes and sizes, addressing the limitations of existing technologies in terms of narrow applicability, operational complexity, and high cost. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism for a pearl drilling machine, which solves the problem that traditional feeding mechanisms in the prior art are usually designed for pearls of specific shapes and sizes. If pearls of different shapes need to be processed, special clamps need to be changed frequently. This is not only cumbersome to operate, but also costly. A structure that can pick up and fix pearls of different shapes and sizes is needed to solve the problems of narrow applicability, complex operation and high cost of the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a pearl drilling machine, comprising a suction cup body, a connecting rod disposed on the upper side of the suction cup body, and a fixing rod disposed on the lower side of the suction cup body;

[0006] A rubber suction cup is provided at the lower end of the fixing rod;

[0007] An air suction chamber is provided at the inner middle position of the rubber suction cup, the fixing rod, the suction cup body and the connecting rod;

[0008] An outer rubber sleeve is provided on the outer side of the rubber suction cup, and an outer spring is provided on the upper side of the outer rubber sleeve and at the connection position between the upper and lower plate bodies.

[0009] An inner spring is provided at the outer side of the fixing rod.

[0010] Preferably, the outer rubber is connected to the rubber suction cup via a nested connection method, and the outer rubber is specifically in the shape of a corrugated tube.

[0011] Preferably, the outer spring is connected to the outer rubber via an adhesive connection, and the outer spring is connected to the fixing rod via a bolt connection.

[0012] Preferably, the outer spring has its elastic direction facing downwards, and the inner spring is connected at both ends by welding, a fixing rod, and a rubber suction cup.

[0013] Preferably, a connecting plate is connected to the upper right side of the suction cup body, and the suction cup body is connected to the feeding robotic arm of the pearl drilling machine through the connecting plate by bolt connection.

[0014] Preferably, the upper end of the connecting rod is connected to the air pipe of an external air pump, and a dust-proof mesh is provided at the inner middle position of the rubber suction cup.

[0015] Compared with the prior art, the present invention provides a feeding mechanism for a pearl drilling machine, which has the following beneficial effects:

[0016] 1. The outer spring continuously applies elastic force during the adsorption process, ensuring that the outer rubber sleeve remains tightly adhered to the pearl's surface. This makes the connection between the pearl and the rubber suction cup more secure, effectively preventing the pearl from falling off due to shaking or bumps during handling. Whether in smooth movement or under slight vibrations that may occur during equipment operation, it ensures that the pearl is firmly gripped, greatly improving the reliability of feeding and reducing the risk of production interruptions or product damage caused by pearls falling off.

[0017] 2. The corrugated shape of the rubber outer tube gives it excellent deformability, allowing for comprehensive wrapping of pearls of different shapes and sizes. Whether it's common round pearls or irregularly shaped baroque pearls, a suitable wrapping method can be found. This wide adaptability eliminates the need for the feeding mechanism to equip itself with multiple special clamps for different pearl shapes, greatly improving the equipment's versatility and reducing production costs and operational complexity.

[0018] 3. The outer spring acts as an elastic buffer when the pearl comes into contact with the rubber suction cup. When the pearl is attracted, the outer spring effectively mitigates the impact caused by excessive instantaneous contact force, preventing scratches, cracks, and other damage to the pearl's surface. This protective mechanism is particularly important for pearls, which are relatively fragile, helping to improve the product yield and reduce economic losses caused by pearl damage.

[0019] 4. The synergistic effect of the outer rubber and the outer spring enables the feeding mechanism to quickly and accurately grasp and release pearls. When approaching a pearl, the outer spring rapidly pushes the outer rubber to unfold; when releasing a pearl, the outer spring also allows the outer rubber to quickly detach from the pearl. The entire feeding process is smooth and efficient, reducing the feeding time, improving the overall production efficiency of the pearl punching machine, and bringing higher economic benefits to the enterprise.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-5 The feeding mechanism of a pearl punching machine shown includes a suction cup body 1, a connecting rod 2 located on the upper side of the suction cup body 1, and a fixing rod 4 located on the lower side of the suction cup body 1.

[0028] A rubber suction cup 5 is provided at the lower end of the fixing rod 4;

[0029] An air suction chamber 3 is provided at the inner middle position of the rubber suction cup 5, the fixing rod 4, the suction cup body 1 and the connecting rod 2;

[0030] An outer rubber 6 is provided on the outer side of the rubber suction cup 5, and an outer spring 7 is provided on the upper side of the outer rubber 6 and at the connection position between the lower plate body;

[0031] An inner spring 8 is provided at the outer side of the fixing rod 4.

[0032] In this embodiment, during the connection and preparation phase, the suction cup body 1 is securely connected to the loading robotic arm via bolts using the connecting plate 9, ensuring that it will not shift or fall off during subsequent operations. Simultaneously, the upper end of the connecting rod 2 is connected to an external air pump hose, providing an air source for generating suction. The dust filter inside the rubber suction cup 5 is always on standby to prevent dust and impurities from entering the suction chamber 3, ensuring stable operation of the air pump.

[0033] When approaching the pearl, the loading robotic arm uses its power to precisely move the entire loading mechanism directly above the pearl. At this point, the outer spring 7 comes into contact with the pearl first. Because its elastic direction is downward, it is compressed after being subjected to the reverse force of the pearl. This compression force then pushes the outer rubber 6, which has a corrugated tube shape, to begin to spread downward, preparing for the next step of wrapping the pearl.

[0034] Entering the pearl adsorption stage, as the feeding mechanism continues to descend, the outer rubber 6 gradually conforms to the contour of the pearl, tightly enveloping it. At this time, the external air pump starts, generating strong suction through the suction chamber 3 to the rubber suction cup 5. During this process, the elasticity of the outer spring 7 continues to play a role, ensuring that the outer rubber 6 remains tightly attached to the pearl surface. At the same time, the inner spring 8 also plays a role in buffering and assisting in fixation, further enhancing the connection and stability between the rubber suction cup 5 and the pearl, ensuring that the pearl is firmly adsorbed.

[0035] During the pearl handling stage, the loading robotic arm carries the loading mechanism that holds the pearls and moves smoothly to the drilling position of the pearl drilling machine, making full preparations for the upcoming drilling operation.

[0036] Finally, during the pearl release phase, once the pearl reaches the designated position, the air pump stops working, and the suction force of the rubber suction cup 5 disappears. The loading robotic arm rises upward, during which the outer spring 7 and inner spring 8 return to their initial state, the outer rubber 6 separates smoothly from the pearl, and the pearl is precisely placed at the punched position. Thus, the entire loading process is perfectly completed.

[0037] like Figure 1-5As shown, the outer rubber 6 is connected to the rubber suction cup 5 by a nested connection method, and the outer rubber 6 is specifically corrugated. The outer spring 7 is connected to the outer rubber 6 by an adhesive connection method, and the outer spring 7 is connected to the fixing rod 4 by a bolt connection method. The elastic direction of the outer spring 7 is downward. The inner spring 8 is connected to the fixing rod 4 and the rubber suction cup 5 by welding at both ends. A connecting plate 9 is connected to the upper right side of the suction cup body 1, and the suction cup body 1 is connected to the feeding robot arm of the pearl punching machine by bolt connection through the connecting plate 9. The upper end of the connecting rod 2 is connected to the air pipe of the external air pump. A dust-proof net is set at the middle inner side of the rubber suction cup 5.

[0038] Preferably, the outer spring 7 takes effect first when approaching the pearl. Because its elastic direction is downward, as the entire feeding mechanism moves above the pearl with the feeding arm and gradually descends, the outer spring 7 is the first to contact the pearl. Upon being subjected to the reverse force of the pearl, the outer spring 7 is compressed, and the force generated by this compression pushes the corrugated rubber outer sleeve 6 to begin spreading downwards. This pushing action of the outer spring 7 provides the initial propulsion for the outer rubber sleeve 6 to adapt to the contours of pearls of different shapes and sizes.

[0039] Entering the pearl adsorption stage, the outer rubber 6 demonstrates its unique adaptability. As the feeding mechanism continues to descend, the outer rubber 6, with its deformable corrugated shape, gradually and tightly conforms to the pearl's contour, completely enveloping it. At this point, the external air pump activates, and the rubber suction cup 5 generates suction to adsorb the pearl. Throughout this process, the outer spring 7 continuously applies elastic force, ensuring that the outer rubber 6 remains firmly attached to the pearl's surface, enhancing the connection stability between the pearl and the rubber suction cup 5. Whether it's a regularly shaped round pearl or irregularly shaped pearls, the outer rubber 6 can effectively envelop it, greatly improving the success rate of grasping pearls of different shapes and sizes.

[0040] Meanwhile, the outer spring 7 also acts as a buffer during the adsorption process. When the pearl comes into contact with the rubber suction cup 5, the elastic buffer of the outer spring 7 can prevent damage to the pearl due to excessive instantaneous contact force, and also prevent impact on the entire feeding mechanism.

[0041] During the pearl release phase, the outer spring 7 and the outer rubber 6 exhibit different behaviors. When the air pump stops working and the loading robotic arm rises, the outer spring 7 returns to its original state, and its elasticity causes the outer rubber 6 to gradually separate from the pearl. Due to the resetting action of the outer spring 7, the outer rubber 6 can quickly and smoothly detach from the pearl surface, ensuring that the pearl can be accurately placed at the drilling position, while also preparing for the next loading operation.

[0042] Optionally, the outer spring 7 passes through the outer rubber 6 and is connected to the bottom inner side of the corrugated outer rubber 6.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
