Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a vacuum nozzle assembly for a gripping robot arm on a board. Background Technology

[0002] In modern industrial production, the loading machine is a key piece of equipment for realizing automated production processes, and the performance of its gripping robot directly affects production efficiency and product quality. With the increasing demand for automated and intelligent manufacturing in the manufacturing industry, loading machine gripping robots have been widely used in many industries such as electronics, semiconductors, and automobile manufacturing. They can quickly and accurately grip and transport materials such as sheet metal, reducing manual intervention and improving the continuity and stability of production.

[0003] Existing gripping robots require specific models for different workpiece types, necessitating the preparation of multiple models and increasing costs. Furthermore, their operational stability is insufficient. Significant vibrations occur during high-speed movement and frequent starts and stops, affecting gripping accuracy, leading to inaccurate workpiece positioning, and potentially damaging robot components, thus shortening the equipment's lifespan. Additionally, existing gripping methods struggle to maintain reliable adhesion for workpieces of varying materials and surface conditions, leading to gripping failures and impacting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a vacuum nozzle assembly for a board-mounted gripper robot, in order to solve the problem of poor adaptability of existing board-mounted gripper robots mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The vacuum nozzle assembly for the grasping robot of the board-mounting machine includes a grasping robot arm for the board-mounting machine. The fixed end of the grasping robot arm is equipped with a fixed base, and the movable end of the grasping robot arm is equipped with a vacuum negative pressure pump. The air inlet end of the vacuum negative pressure pump is equipped with a suction cup-shaped negative pressure nozzle. The air inlet end of the vacuum negative pressure pump is connected to an external threaded pipe. The top of the negative pressure nozzle is equipped with an internal threaded connector that is adapted to the size of the external threaded pipe and is threadedly connected. The top of the vacuum negative pressure pump is the air outlet end, and the air outlet end is equipped with a detachable mesh cover.

[0007] Preferably, the bottom of the mounting base is equipped with a shock-absorbing pad, which effectively buffers the vibrations generated by the gripping robotic arm during operation. Because vibrations are transmitted throughout the entire device during frequent starts, stops, and high-speed movements of the robotic arm, affecting its stability and gripping accuracy, the shock-absorbing pad reduces this adverse effect and ensures smooth operation of the device.

[0008] Preferably, the shock-absorbing pad is made of rubber with a thickness of 1-4mm. Rubber has good elasticity and shock absorption performance, which can effectively absorb vibration energy. The thickness range of 1-4mm ensures the shock absorption effect while taking into account the installation space and cost of the shock-absorbing pad, thus achieving a good balance between practicality and economy.

[0009] Preferably, the bottom of the mesh cover is fitted with a plug-in ring seat that matches the inner diameter of the outlet end of the vacuum negative pressure pump, allowing the mesh cover to be securely installed at the outlet end of the vacuum negative pressure pump. This plug-in method facilitates installation and disassembly, ensures a tight connection between the mesh cover and the outlet end, prevents the mesh cover from loosening, effectively blocks debris from entering the pump, and protects the normal operation of the pump.

[0010] Preferably, a sealing gasket is provided at the connection between the externally threaded pipe and the air inlet of the vacuum pump to fill the tiny gaps at the connection and enhance the sealing performance. Poor sealing at the connection can lead to gas leakage, affecting the vacuum pump's ability to generate sufficient negative pressure and consequently impacting the gripping effect. The sealing gasket effectively prevents this problem.

[0011] Preferably, the sealing gasket is a silicone gasket with a thickness of 3-5mm. Silicone has good flexibility and sealing properties, and can adapt to a certain degree of deformation to ensure a sealing effect. The thickness of 3-5mm provides sufficient sealing pressure without affecting the stability of the installation and connection structure due to excessive thickness.

[0012] Preferably, the outer wall of the internally threaded connector is fitted with a shock-absorbing shell, which protects the internally threaded connector during equipment operation. Since the internally threaded connector is a key component connecting the negative pressure nozzle and the vacuum pump, it is susceptible to impacts in the working environment. The shock-absorbing shell reduces damage caused by impacts and extends the component's service life.

[0013] Preferably, the impact-resistant shell is made of metal and coated with anti-corrosion paint. Metal has high strength and impact resistance, effectively resisting collisions. The anti-corrosion paint coating prevents the metal shell from rusting and corroding in harsh environments such as humid and corrosive conditions, further improving the protective performance and service life of the impact-resistant shell.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: In the vacuum nozzle assembly of this upper-trigger gripping robot, the gripping robot arm, as the support and motion execution part of the entire assembly, can move and position flexibly, allowing the vacuum nozzle assembly to accurately reach the target position for gripping operations; the fixed base is installed at the fixed end of the gripping robot arm, playing a role in stable connection and support, enabling the gripping robot arm to work stably; the vacuum negative pressure pump is installed at the movable end of the gripping robot arm, and its air inlet end is connected to an external threaded pipe, which can generate vacuum negative pressure to provide power for sucking up objects; the air outlet end is equipped with a detachable mesh cover to prevent debris from entering the pump, and at the same time facilitates cleaning and maintenance; the top of the negative pressure nozzle is equipped with an internal threaded connector that is adapted to the size of the external threaded pipe and threadedly connected. This connection method makes the negative pressure nozzle and the vacuum negative pressure pump tightly connected and easy to disassemble and replace. The negative pressure nozzle is shaped like a suction cup, which can better fit the surface of the object being sucked up, improving the stability and reliability of suction; the overall structure works in concert, enabling the vacuum nozzle assembly of the upper-trigger gripping robot to complete the gripping task efficiently and stably.

[0025] The vacuum nozzle assembly of the upper-plate gripper robotic arm, such as... Figures 1-3 As shown, the assembly includes a gripping robotic arm 10 for mounting the upper plate. A fixed base 20 is mounted on the fixed end of the gripping robotic arm 10, and a vacuum negative pressure pump 30 is mounted on the movable end. A suction cup-shaped negative pressure nozzle 40 is mounted on the air inlet end of the vacuum negative pressure pump 30. An external threaded pipe 33 is connected to the air inlet end of the vacuum negative pressure pump 30. An internal threaded connector 42, matching the size of the external threaded pipe 33 and threadedly connected, is mounted on the top of the negative pressure nozzle 40. The top of the vacuum negative pressure pump 30 is the air outlet end, which is equipped with a detachable mesh cover 31. The gripping robotic arm 10, serving as the support and motion execution part of the entire assembly, can move and position flexibly, allowing the vacuum nozzle assembly to accurately reach the target position for gripping operations. The fixed base 20 is mounted on the fixed end of the gripping robotic arm 10, serving as... The vacuum pump 30 provides a stable connection and support, enabling the gripping robotic arm 10 to operate stably. Its inlet end is connected to an external threaded pipe 33, generating a vacuum to power the suction of objects. A removable mesh cover 31 at the outlet prevents debris from entering the pump and facilitates cleaning and maintenance. The top of the negative pressure suction nozzle 40 is fitted with an internal threaded connector 42 that matches the size of the external threaded pipe 33. This connection method ensures a tight connection between the negative pressure suction nozzle 40 and the vacuum pump 30, facilitating disassembly and replacement. The suction nozzle 40, shaped like a suction cup, better conforms to the surface of the object being gripped, improving suction stability and reliability. The coordinated operation of the entire structure allows the vacuum suction nozzle assembly of the upper-plate gripping robotic arm to efficiently and stably complete the gripping task.

[0026] Furthermore, a shock-absorbing pad 21 is installed at the bottom of the fixed base 20. The shock-absorbing pad 21 is made of rubber and has a thickness of 1-4mm, which can effectively buffer the vibration generated during the operation of the gripping robotic arm 10, reduce the impact of vibration on the overall stability and accuracy of the equipment, and improve the smoothness of equipment operation.

[0027] Specifically, the bottom of the mesh cover 31 is equipped with a plug-in ring seat 32 that is compatible with the inner diameter of the outlet end of the vacuum negative pressure pump 30 and fits into place. This allows the mesh cover 31 to be securely installed at the outlet end of the vacuum negative pressure pump 30, making installation and disassembly convenient and effectively preventing the mesh cover 31 from loosening and falling off, thus ensuring the blocking effect on debris.

[0028] A sealing gasket 34 is provided at the connection between the external threaded pipe 33 and the air inlet end of the vacuum negative pressure pump 30. The sealing gasket 34 is a silicone gasket with a thickness of 3-5mm, which significantly improves the sealing performance between the external threaded pipe 33 and the internal threaded connector 42, effectively preventing gas leakage and ensuring that the vacuum negative pressure pump 30 can generate sufficient negative pressure for gripping operations.

[0029] In addition, an anti-collision shell 43 is installed on the outer wall of the internal thread connector 42. The anti-collision shell 43 is made of metal and coated with anti-corrosion paint, which can effectively protect the internal thread connector 42 during equipment operation and prevent damage due to collision. At the same time, the anti-corrosion paint can prevent the metal shell from rusting and corroding, and extend the service life of the equipment.

[0030] Working principle of the vacuum nozzle assembly of the trigger gripper robot:

[0031] First, the gripping robotic arm 10 is securely installed in the predetermined position by the mounting base 20. The shock-absorbing pad 21 at its bottom can effectively reduce vibration during operation, providing a foundation for subsequent stable operation.

[0032] Next, select the corresponding size of the negative pressure suction nozzle 40 according to the model of the workpiece. Different models of workpieces may require different shapes and sizes of suction nozzles to ensure good adsorption effect. After selecting the appropriate negative pressure suction nozzle 40, connect the internal threaded connector 42 at the top of it to the external threaded pipe 33 at the air inlet end of the vacuum negative pressure pump 30. The sealing gasket 34 at the connection between the external threaded pipe 33 and the air inlet end of the vacuum negative pressure pump 30 can ensure the sealing of the connection and prevent gas leakage. During this process, the anti-collision shell 43 on the outer wall of the internal threaded connector 42 can protect it and avoid collision damage during installation.

[0033] Then, the vacuum negative pressure pump 30 is started, and the negative pressure suction nozzle 40 generates a strong suction force to adsorb the workpiece; the mesh cover 31 at the air outlet of the vacuum negative pressure pump 30 is securely installed through the plug-in ring seat 32 to prevent foreign objects from entering the pump and affecting its normal operation. Then, the gripping robotic arm 10 moves the adsorbed workpiece to the designated position.

[0034] Finally, the vacuum negative pressure pump 30 stops working, the negative pressure disappears, and the workpiece is placed in the designated position, completing one gripping operation; the various structures in the entire process work together to efficiently complete the workpiece gripping task.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
