Description

Technical Field

[0001] This utility model relates to the field of industrial equipment parts installation and commissioning technology, and in particular to a quick-change component and a material suction module. Background Technology

[0002] In industrial equipment, suction cups are commonly used to grip, move, or secure workpieces. In existing technology, suction cups are typically connected to a mounting base using screws. The screws pass through the mounting holes of the suction cup and are screwed into the threaded holes of the mounting base. The engagement force of the threads secures the suction cup to the mounting base. The mounting holes of the suction cup are usually designed to be circular or elongated to accommodate different installation requirements. The specifications and number of screws are selected based on the size of the suction cup and the load requirements. While this fixing method provides strong stability and reliability, it has some significant drawbacks in practical applications, especially in scenarios where frequent replacement or adjustment of the suction cup is required:

[0003] (1) Cumbersome disassembly and assembly: Each time the suction cup is replaced or adjusted, tools (such as screwdrivers or wrenches) are required to tighten or loosen the screws, which involves many steps and takes a long time; (2) Strong tool dependence: The disassembly and assembly process must rely on specific tools. If the tools are not complete or lost, disassembly and assembly cannot be carried out; (3) Screws are easy to lose: During frequent disassembly and assembly, screws are easy to lose or be damaged, which increases maintenance costs; (4) High installation accuracy requirements: Screw fixing requires precise alignment of the mounting holes, especially when multiple screws are fixed. Deviations are easy to occur during installation, affecting the stability of the suction cup; (5) Damage to the base: Frequent tightening of screws may cause wear on the threaded holes of the base, resulting in loose screws or inability to tighten them.

[0015] In an optional embodiment, the elastic limiting component includes a first component and a second component, the first component and the second component respectively including a spring and a limiting pin, the spring being sleeved on the outside of the limiting pin;

[0016] The mounting base has two first limiting holes on the side wall opposite to the side opening of the base, and the quick-change block has two second limiting holes on the outer side wall opposite to the side opening of the base. The rod of the limiting pin of the first component passes through one of the first limiting holes and is inserted and slidably installed in one of the second limiting holes along the axial direction of the limiting pin. The rod of the limiting pin of the second component passes through the other first limiting hole and is inserted and slidably installed in the other of the second limiting holes along the axial direction of the limiting pin.

[0017] In an optional embodiment, the rod portion of the limiting pin includes a main rod and a protrusion fixedly connected to one end of the main rod facing the quick-change block.

The protrusion is inserted into and slidably installed inside the corresponding second limiting hole, and the main rod is limited to the outside of the second limiting hole by the shoulder structure.

[0018] In an optional embodiment, the elastic limiting assembly further includes a central spring. A limiting groove is provided on the inner sidewall of the mounting base on the side opposite to the side opening of the base. The limiting groove is located between the two first limiting holes. One end of the central spring abuts against the outer sidewall of the quick-change block on the side opposite to the side opening of the base, and the other end is inserted into the limiting groove.

[0019] In an optional embodiment, the positioning groove on the outer wall of the insertion end of the suction module dock is an annular groove surrounding the circumference of the insertion end; the inner wall of the positioning protrusion on the inner side of the card block insertion hole has an arc-shaped surface that matches the annular groove.

[0020] Secondly, this utility model provides a material suction module, including a threaded connecting pipe fitting and a quick-change assembly for the material suction module as described in any optional embodiment of the first aspect; wherein:

[0021] The threaded connector is installed inside the base socket and one end of it protrudes from the mounting base.

[0022] In an optional embodiment, the quick-change assembly of the suction module further includes a rotary motor and an air connector;

[0023] The rotary motor has a hollow shaft, which is threadedly connected to one end of the threaded connector protruding from the mounting base. The air connector is fixedly connected to the housing of the rotary motor and is connected to the hollow shaft. The gas passages provided in the cavity of the threaded connector and the air connector are all in communication with the inner cavity of the hollow shaft.

[0024] This utility model can achieve at least the following beneficial effects:

[0025] In use, the end of the suction module docking seat away from the plug-in end is used to connect the suction cup. The mounting base is used to fix it on the robotic arm or the adapter connected to the robotic arm, and it is connected to the air pipe connector. The gas channel inside the air pipe connector is connected to the base socket. As shown in Figure 1-2, when the suction module quick-change assembly is in the docking state: the plug-in end is inserted into the card block socket and the base socket. The positioning protrusion is positioned inside the positioning groove under the elastic force of the elastic limiting component. The gas channel inside the plug-in end is connected to the gas channel inside the air pipe connector. When disassembling, as shown in Figure 2-3, when the suction module quick-change assembly is in the disassembly state: press the quick-change card block into the inner cavity of the base. The elastic limiting component is compressed, so that the positioning protrusion is disengaged from the positioning groove. Then the plug-in end of the suction module docking seat can be removed from the base socket and the card block socket.

[0026] This invention, through a uniquely designed quick-change latch and elastic limiting component, enables rapid docking and disassembly between the suction cup and a robotic arm or an adapter connected to the robotic arm. Specifically, in the docked state, the positioning protrusion is positioned inside the positioning groove under the elastic force of the elastic limiting component, ensuring a secure connection between the suction module docking seat and the suction cup. During disassembly, simply pressing the quick-change latch into the base cavity compresses the elastic limiting component, allowing the positioning protrusion to disengage from the positioning groove and easily exit the connector. This design significantly improves operational efficiency and provides precise and reliable alignment. The disassembly and assembly process does not damage components, making it particularly suitable for scenarios requiring frequent suction cup replacements.

[0027] The quick-change suction module assembly provided by this utility model can be flexibly applied to various industrial automation scenarios, such as robot gripping systems and material handling equipment. Whether it's suction cups of different sizes or different types of robotic arms or adapters, diverse needs can be met simply by adapting the corresponding mounting base and suction module docking seat. Furthermore, its modular design facilitates maintenance and upgrades, reducing long-term operating costs. Attached Figure Description

[0051] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0052] First aspect

[0053] This embodiment provides a quick-change component for a material suction module, see reference. Figures 1 to 13 The quick-change assembly of the suction module includes a mounting base 1, a quick-change block 2, and a suction module docking seat 3. Specifically, the mounting base 1 has an inner cavity, a longitudinally penetrating base insertion hole 11, and a base side opening 12 communicating with the inner cavity; the quick-change block 2 is inserted into the inner cavity of the mounting base 1 through the base side opening 12; an elastic limiting component 4 is provided between the quick-change block 2 and the inner wall of the mounting base 1. The quick-change block 2 has a longitudinally penetrating block insertion hole 21; a positioning protrusion 22 is provided on the inner side of the block insertion hole 21. The suction module docking seat 3 includes a docking seat body 31 and an insertion end 32 connected axially, and a positioning groove 321 is provided on the outer side wall of the insertion end 32; an air channel 301 axially penetrating the docking seat body 31 and the insertion end 32 is provided inside the suction module docking seat 3.

[0054] In the assembled state, the plug end 32 is inserted into the card block socket 21 and the base socket 11. The positioning protrusion 22 is positioned inside the positioning groove 321 under the elastic force of the elastic limiting component 4. The elastic limiting component 4 can be compressed when the quick-change card block 2 is pressed into the inner cavity of the base, so that the positioning protrusion 22 is disengaged from the positioning groove 321.

[0055] In use, the end of the docking body 31 of the suction module docking seat 3 furthest from the insertion end 32 is used to connect to the suction cup. The mounting base 1 is used to fix it on the robotic arm or the adapter connected to the robotic arm, and it is connected to the air pipe connector. The gas channel inside the air pipe connector communicates with the base insertion hole 11. Figures 10-14 As shown, when the quick-change assembly of the suction module is in the docking state: the plug end 32 is inserted into the card block socket 21 and the base socket 11, and the positioning protrusion 22 is positioned inside the positioning groove 321 under the elastic force of the elastic limiting component 4. The gas channel 301 provided inside the plug end 32 is connected to the gas channel provided inside the air pipe connector; when disassembling, as Figures 6-9As shown, the quick-change assembly of the suction module is in a disassembled working state: when the quick-change block 2 is pressed into the inner cavity of the base, the elastic limiting component 4 is compressed, so that the positioning protrusion 22 is disengaged from the positioning groove 321, and the insertion end 32 of the suction module docking seat 3 can be removed from the base insertion hole 11 and the block insertion hole 21.

[0056] This embodiment, through the unique design of the quick-change latch 2 and the elastic limiting component 4, enables rapid docking and disassembly between the suction cup and the robotic arm or the adapter connected to the robotic arm. Specifically, in the docked state, the positioning protrusion 22 is positioned inside the positioning groove 321 under the elastic force of the elastic limiting component 4, ensuring a secure connection between the suction module docking seat 3 and the suction module docking seat 3. During disassembly, simply pressing the quick-change latch 2 into the base cavity compresses the elastic limiting component 4, allowing the positioning protrusion 22 to disengage from the positioning groove 321 and easily exit the insertion end 32. This design significantly improves operational efficiency and provides precise and reliable alignment. The disassembly and assembly process does not damage components, making it particularly suitable for scenarios requiring frequent suction cup replacements.

[0057] The quick-change suction module assembly provided in this embodiment can be flexibly applied to various industrial automation scenarios, such as robot gripping systems and material handling equipment. Whether it's suction cups of different sizes or different types of robotic arms or adapters, simply adapting the corresponding mounting base 1 and suction module docking seat 3 can meet diverse needs. Furthermore, its modular design facilitates maintenance and upgrades, reducing long-term operating costs.

[0058] In an optional embodiment of this example, the quick-change assembly of the suction module further includes a tubular seal 5 made of elastic material. The tubular seal 5 is press-fitted into and communicates with the gas channel 301, with one end of the tubular seal 5 protruding from the insertion end 32 and facing away from the end surface of the docking seat body 31. This optional embodiment effectively reduces the possibility of gas leakage by press-fitting the tubular seal 5 into and communicating with the gas channel 301. The elastic properties of the tubular seal 5 allow it to fit tightly against the inner wall of the gas channel 301, thereby significantly improving the airtightness of the entire quick-change assembly of the suction module. Furthermore, since one end of the tubular seal 5 protrudes from the insertion end 32 and faces away from the end surface of the docking seat body 31, during the process of the gas channel inside the gas pipe connector connecting to the gas channel 301 via a pipe connector or hollow shaft, the exposed portion of the tubular seal 5 provides guidance and buffering, preventing damage caused by hard contact during connection, and further ensuring the sealing and stable reliability of the connection.

[0059] In an optional embodiment of this invention, the quick-change assembly of the suction module further includes a sealing ring 6. The sealing ring 6 is fixedly connected to the end surface of the docking seat body 31 opposite to the insertion end 32. The opening of the gas channel 301 on the docking seat body 31 is located inside the space surrounded by the sealing ring 6. Since the sealing ring 6 surrounds the opening of the gas channel 301, it ensures that no gas leakage occurs during the docking of the suction cup and the docking seat body 31, further enhancing the airtightness.

[0060] In an optional embodiment of this example, the elastic limiting component 4 includes at least one spring; one end of the spring abuts against the outer side wall of the quick-change block 2 opposite to the base-side opening 12, and the other end abuts against the inner side wall of the mounting base 1 opposite to the base-side opening 12. In this optional embodiment, an elastic connection is established between the quick-change block 2 and the mounting base 1 by at least one spring, ensuring that the quick-change block 2 can still maintain a stable connection under external vibration or impact. This design effectively avoids connection failure caused by mechanical loosening.

[0061] Optionally, the elastic limiting component 4 includes a first component 41 and a second component 42. The first component 41 and the second component 42 each include their own springs and limiting pins, with the springs fitted around the limiting pins. Two first limiting holes 101 are provided on the side wall of the mounting base 1 opposite to the base side opening 12. Two second limiting holes 201 are provided on the outer side wall of the quick-change block 2 opposite to the base side opening 12. The rod of the limiting pin of the first component 41 passes through one first limiting hole 101 and is inserted and slidably installed in one second limiting hole 201 along the pin's axial direction. The rod of the limiting pin of the second component 42 passes through the other first limiting hole 101 and is inserted and slidably installed in the other second limiting hole 201 along the pin's axial direction. The first component 41 and the second component 42, through their respective springs and limiting pins, enable quick installation and disassembly between the quick-change block 2 and the mounting base 1, allowing the structure to adapt to different installation scenarios and load conditions. For example, under heavy loads, the first component 41 and the second component 42 can work together to provide greater elastic support.

[0062] Optionally, the shank of the limiting pin includes a main body and a protrusion fixedly connected to the end of the main body facing the quick-change block 2. The diameter of the protrusion is smaller than the diameter of the main body to form a shoulder structure at the connection between the main body and the protrusion. The protrusion is inserted into and slidably installed inside the corresponding second limiting hole 201, and the main body is limited to the outside of the second limiting hole 201 by the shoulder structure. The shank design of the limiting pin (including the main body, the protrusion, and the shoulder structure) allows the limiting pin to slide axially between the first limiting hole 101 and the second limiting hole 201, while the shoulder structure restricts its excessive sliding out, thereby achieving a flexible and reliable limiting function.

[0063] Optionally, the elastic limiting assembly 4 further includes a central spring 43. A limiting groove 102 is provided on the inner wall of the mounting base 1 on the side opposite to the base side opening 12. The limiting groove 102 is located between the two first limiting holes 101. One end of the central spring 43 abuts against the outer wall of the quick-change block 2 on the side opposite to the base side opening 12, and the other end is inserted into the limiting groove 102. The introduction of the central spring 43 further enhances the connection strength between the quick-change block 2 and the mounting base 1. One end of the central spring 43 abuts against the outer wall of the quick-change block 2, and the other end is inserted into the limiting groove 102, forming additional elastic support. This design not only improves the overall structure's impact resistance but also reduces the direct rigid contact between the quick-change block 2 and the mounting base 1, thereby reducing the risk of wear.

[0064] In an optional embodiment of this invention, the positioning groove 321 on the outer wall of the insertion end 32 of the suction module docking seat 3 is an annular groove surrounding the insertion end 32; the inner wall of the positioning protrusion 22 on the inner side of the locking block insertion hole 21 has an arc-shaped surface that matches the annular groove. The design of the positioning groove 321 as an annular groove allows the insertion end 32 to be effectively locked at any rotation angle. Since the annular groove does not need to be precisely aligned with a specific direction to complete insertion and locking, it greatly reduces the assembly difficulty, improves production efficiency, and enhances the flexibility and adaptability of the system, making it particularly suitable for application scenarios that require frequent adjustments to angles or directions.

[0065] Second aspect

[0066] This utility model also provides a material suction module, see reference. Figure 14 and Figure 15 The suction module includes a threaded connector 7 and a quick-change assembly for the suction module provided in any of the optional embodiments of the first aspect. The threaded connector 7 is installed inside the base insertion hole 11 with one end protruding from the mounting base 1. The cavity of the threaded connector 7 is connected to the gas channel 301. The outer circumferential surface of the end of the threaded connector 7 protruding from the mounting base 1 is provided with an external thread. Thus, the gas channel inside the gas pipe connector can be threadedly connected to the threaded connector 7 through a pipe fitting or hollow shaft, etc., to ensure the sealing and stable reliability of the connection path between the gas channel inside the gas pipe connector and the gas channel 301. This design can effectively reduce the risk of gas leakage and improve the stability of system operation.

[0067] Optionally, the quick-change assembly of the material suction module also includes a rotary motor 8 and an air connector 9. The rotary motor 8 has a hollow shaft 81, which is threadedly connected to one end of a threaded connector 7 exposed on the mounting base 1. The air connector 9 is fixedly connected to the housing of the rotary motor 8 and mates with the hollow shaft 81. The gas channels provided in the cavity of the threaded connector 7 and inside the air connector 9 are interconnected with the inner cavity of the hollow shaft 81. By introducing the rotary motor 8 and its hollow shaft 81, dynamic support for the air path is achieved during the operation of the material suction module. Specifically, the threaded connection between the hollow shaft 81 and the threaded connector 7 not only ensures unobstructed air path but also supports rotational operation, expanding the application scenarios of the module.

[0068] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to mutually. The above embodiments in this specification are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model.
