Description

Technical Field

[0001] This invention belongs to the field of fire-fighting equipment manufacturing technology, and specifically relates to a fire hose connector sealing gasket assembly device based on an industrial robot. Background Technology

[0002] A fire hose set typically consists of a fire hose, connectors, nozzles, and related accessories. The connectors are used to connect the hoses to other hoses, fire hydrants, fire pumps, nozzles, etc., and the sealing ring seat of the connector interface usually needs to be fitted with a sealing gasket, located inside the interface. When two connectors are connected, the sealing gasket plays a sealing role at the connection point of the interface.

[0003] A search revealed that Chinese Patent Publication No. CN117182506B, published on January 2, 2024, discloses a sealing gasket assembly device for fire hose connectors. The device includes an assembly machine tool with a support frame fixedly mounted on it. It also includes a lifting platform, one end of which is slidably connected to the support frame, and a sealing gasket assembly box fixedly mounted on the lifting platform. A feeding cylinder is located in the center of the sealing gasket assembly box. Multiple rotating plates are circumferentially distributed within the sealing gasket assembly box and rotatably connected to the inner wall of the box via torque seats. An inclined smooth plate is fixedly mounted at the bottom of each rotating plate, and a connector body is positioned between the multiple inclined smooth plates. This fire hose connector sealing gasket assembly device avoids tilting when the sealing gasket contacts the connector body, improving the sealing effect and preventing damage to the sealing ring or compression device due to misalignment.

[0015] Furthermore, each set of extension plates has a set of racks on its outer wall; each set of racks is fan-shaped and moves through the telescopic cavity; several sets of guide gears are evenly spaced on the inner wall of the telescopic cavity on the side away from the central axis of the guide plate; each set of racks is meshed with the corresponding several sets of guide gears.

[0019] The beneficial effects of this invention are:

[0020] 1. By controlling the industrial robotic arm to move the clamping block to the corresponding position, and then controlling two sets of clamping plates to clamp the fire hose connector, several sets of limiting rollers abut against the outer wall of the connector. After flipping the connector, the drive wheel is controlled to abut against the outer wall of the connector to drive the connector to rotate, which can connect the two connectors. Then, the jet nozzle is controlled to enter the corresponding connector to deliver gas. Then, by monitoring whether there is air leakage at the connection, the assembly effect of the sealing gasket is judged. This realizes the integrated drive effect of loading, unloading and sorting of fire hose connectors, optimizes the assembly process, and improves the assembly effect of the assembly equipment while improving the sealing detection efficiency of fire hose connectors.

[0021] 2. By controlling the annular sealing gasket on the sealing gasket assembly box to be pressed into the sealing ring seat of the connector interface, the lifting plate is then controlled to rise, and then several sets of electric folding rods at the bottom of the rotating ring are controlled to move the detector to the assembled sealing gasket, so that several sets of telescopic probes abut against the top of the sealing gasket. Then, the rotating ring is controlled to drive several sets of detectors to rotate continuously. By monitoring and recording the feedback pressure of the telescopic probes, it is confirmed whether the sealing gasket is flat. When the sealing gasket is not flat, the pressure ring on the detector is controlled to abut against the top of the sealing gasket, and the telescopic probe is pressed into the detector. Then, several sets of pressure rings are controlled to rotate one revolution to flatten the sealing gasket, which improves the assembly quality of the connector sealing gasket of the assembly equipment.

[0022] 3. The fire hose connector assembled by the loading and unloading mechanism is unloaded and flipped. Then, the loading and unloading mechanism connects the flipped connector to the next set of connectors to maintain communication. Gas is then introduced into the connector. Since the bottom of the connector below can be sealed, several sets of first and second air pressure sensors installed on the guide plate and the inner walls of the two sets of extension plates detect air leakage at the connection point of the two sets of connectors. The two sets of extension plates can be controlled by guide gears to retract into the telescopic cavity. Without affecting the loading and unloading of fire hose connectors, the quality of the assembly equipment's detection of the airtightness of the assembled fire hose connectors is improved.

[0023] 4. The loading and unloading mechanism sequentially transfers the fire hose connectors into several sets of assembly slots on the circulating transfer mechanism. The interface of the connector is secured to the support plate, and a corresponding lifting baffle can be installed below the support plate to support the bottom of the connector. Subsequently, two sets of limit rods are controlled to limit and fix the connector to prevent displacement during assembly. When the fire hose connector completes the sealing gasket assembly on the rotating plate and moves back to the loading and unloading robot, the loading and unloading mechanism unloads the assembled fire hose connector and installs a new fire hose connector. This ensures the continuity of the sealing gasket assembly work of the fire hose connector and improves the working efficiency of the assembly equipment.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0037] This invention provides a fire hose connector sealing gasket assembly device based on an industrial robot, including an assembly machine tool 1. For example, as shown... Figure 1 As shown, a sealing gasket assembly mechanism 2 is provided at one edge of the top of the assembly machine tool 1; a circulating transfer mechanism 3 is provided at the center of the top of the assembly machine tool 1; an industrial robotic arm 4 is provided at one edge of the top of the assembly machine tool 1 away from the sealing gasket assembly mechanism 2; a loading and unloading mechanism 5 is connected to the output end of the industrial robotic arm 4; the industrial robotic arm 4 and the loading and unloading mechanism 5 are combined to form a loading and unloading robot; a set of storage boxes 6 are provided on both sides of the loading and unloading mechanism 5.

[0038] As the driving part of the loading and unloading robot, the industrial robotic arm 4 drives the loading and unloading mechanism 5 to perform the loading and unloading work when assembling the sealing gasket of the fire hose connector. The fire hose connector is transferred to the circulating transfer mechanism 3 in sequence. When the fire hose connector completes the sealing gasket assembly on the circulating transfer mechanism 3 and moves back to the loading and unloading robot, the loading and unloading mechanism 5 unloads the assembled fire hose connector and inserts a new fire hose connector, thereby ensuring the continuity of the sealing gasket assembly work of the fire hose connector.

[0039] For example, such as Figure 2 and Figure 3 As shown, the sealing gasket assembly mechanism 2 includes a mounting plate 201; a lifting guide rail 202 is provided on one side wall of the mounting plate 201 near the circulating transfer mechanism 3; a lifting plate 203 is drivenly connected to the lifting guide rail 202; a sealing gasket assembly box 204 is provided on the top of the lifting plate 203; the output end of the sealing gasket assembly box 204 extends to the bottom of the lifting plate 203, and a guide ring 205 is sleeved on its outer wall; a rotating ring 206 is drivenly connected to the outer wall of the guide ring 205; the rotating ring... Several sets of first movable slots 207 are arranged in a ring array at the bottom edge of 206; each set of first movable slots 207 is provided with a set of electric folding rods 208; each set of electric folding rods 208 is provided with a set of detectors 209 at the end away from the rotating ring 206; each set of detectors 209 is provided with a set of pressure rings 210 on one side wall; each set of detectors 209 is provided with a set of telescopic probes 211 on one side wall; each set of telescopic probes 211 moves through the pressure rings 210.

[0040] When assembling the sealing gasket of the fire hose connector, the lifting guide rail 202 is controlled to drive the lifting plate 203 to descend, so that the annular sealing gasket at the output end of the sealing gasket assembly box 204 is pressed into the sealing ring seat of the connector interface. Then, the lifting plate 203 is controlled to rise, and then several sets of electric folding rods 208 at the bottom of the rotating ring 206 are controlled to move the detector 209 to the assembled sealing gasket, so that several sets of telescopic probes 211 abut against the top of the sealing gasket. Then, the rotating ring 206 is controlled to drive several sets of detectors 209 to rotate continuously. By monitoring and recording the feedback pressure of the telescopic probes, it is confirmed whether the sealing gasket is flat. When the sealing gasket is not flat, the pressure ring 210 on the detector 209 is controlled to abut against the top of the sealing gasket, and the telescopic probes 211 are pressed into the detector 209. Then, the pressure rings 210 are controlled to rotate one revolution to flatten the sealing gasket, which improves the working quality of the assembly equipment.

[0041] For example, such as Figure 4 and Figure 5The circulating transfer mechanism 3 includes a rotating seat 301; a rotating disk 302 is drivenly connected to the top of the rotating seat 301; several sets of assembly slots 303 are arranged in a ring array on the side wall of the rotating disk 302; a set of support plates 304 are provided in each set of assembly slots 303; each set of support plates 304 is semi-circular and has a set of limiting stops 305 at both ends; a set of first sliding grooves 306 are provided on the inner wall of each set of assembly slots 303 in the direction close to the central axis of the rotating disk; a set of sealing detection components 307 are slidably connected in each set of first sliding grooves 306; a set of first lead screws 308 are provided in each set of first sliding grooves 306 in the vertical direction; a set of first sliders 309 are slidably connected in each set of first sliding grooves 306 in the vertical direction; and each set of first sliders 309 is threadedly connected to the corresponding set of first lead screws 308.

[0042] During the assembly of the sealing gasket for the fire hose connector, the loading and unloading mechanism 5 sequentially transfers the fire hose connector to several sets of assembly slots 303 on the circulating transfer mechanism 3. The interface of the connector is secured to the support plate 304. A corresponding lifting baffle can be installed below the support plate 304 to support the bottom of the connector. Subsequently, two sets of limit stops are controlled to limit and fix the connector to prevent displacement during assembly. When the fire hose connector completes the sealing gasket assembly on the rotating plate 302 and moves back to the loading and unloading robot, the loading and unloading mechanism 5 removes the assembled fire hose connector and inserts a new fire hose connector. This ensures the continuity of the sealing gasket assembly work for the fire hose connector and improves the working efficiency of the assembly equipment.

[0043] For example, such as Figure 6 and Figure 7 As shown, the sealing detection component 307 includes a guide plate 3071; the guide plate 3071 is semi-circular, and a plurality of first wind pressure sensors 3072 are evenly spaced on its inner wall; a telescopic cavity 3073 is provided inside the guide plate 3071; two sets of extension plates 3074 are symmetrically and movably inserted through both ends of the telescopic cavity 3073; each set of extension plates 3074 is fan-shaped, and a plurality of second wind pressure sensors 3075 are evenly spaced on its inner wall; a set of racks 3076 is provided on the outer wall of each set of extension plates 3074; each set of racks 3076 is fan-shaped and movably inserted through the telescopic cavity 3073; a plurality of guide gears 3077 are evenly spaced on the inner wall of the telescopic cavity 3073 on the side away from the central axis of the guide plate 3071; each set of racks 3076 is meshed with the corresponding plurality of guide gears 3077.

[0044] During the assembly of the sealing gasket for the fire hose connector, the assembled fire hose connector is unloaded and flipped by the loading and unloading mechanism 5. Then, the loading and unloading mechanism 5 connects the flipped connector to the next set of connectors to maintain communication. Gas is then introduced into the connector. Since the bottom of the connector below can be sealed, several sets of first air pressure sensors 3072 and second air pressure sensors 3075 set on the inner walls of the guide plate 3071 and the two sets of extension plates 3074 can detect air leakage at the connection point of the two sets of connectors. The two sets of extension plates 3074 can be controlled by the guide gear 3077 to retract into the telescopic cavity 3073. Without affecting the loading and unloading of the fire hose connector, the quality of the air tightness test of the assembled fire hose connector by the assembly equipment is improved.

[0045] For example, such as Figure 8 and Figure 9 As shown, the loading and unloading mechanism 5 includes an electric turntable 501; a clamping block 502 is drivenly connected to the output end of the electric turntable 501; two sets of second sliding grooves 503 are symmetrically opened on both sides of the side wall away from the electric turntable 501 of the clamping block 502; two sets of clamping plates 504 are symmetrically arranged in the two sets of second sliding grooves 503; each set of clamping plates 504 is fan-shaped, and several sets of limiting rollers 505 are evenly spaced on the inner wall; a second movable groove 506 is opened on the side wall of the clamping block 502 near the clamping plate 504; an electric push rod 507 is provided on the side wall of the second movable groove 506 near the electric turntable 501; a drive wheel 508 is drivenly connected to the output end of the electric push rod 507; a swing rod 509 is provided on the top of the clamping block 502; the swing rod 509 is drivenly connected to the output end of the electric push rod 507; the swing rod 509 is drivenly connected to the output end of the electric push rod 507; the swing rod 509 is drivenly connected to the output end of the electric push rod 507; the swing rod 509 is drivenly connected to the output end of the electric push rod 507; the swing rod 509 is drivenly connected to the output end of the electric push rod 501 ... The end of the moving rod 509 away from the clamping block 502 is connected to a jet head 510; a sealing airbag 511 is provided on the output end of the jet head 510; the sealing airbag 511 is annular and communicates with the jet head 510; an adjustment cavity 512 is provided inside the clamping block 502; two sets of second lead screws 513 are provided inside the adjustment cavity 512; one end of the two sets of second lead screws 513 is fixedly connected, and the other end is rotatably connected to the inner walls on both sides of the adjustment cavity 512; the thread directions of the two sets of second lead screws 513 are opposite, and their central axes are on the same straight line; two sets of second sliders 514 are slidably connected in the horizontal direction inside the adjustment cavity 512; each set of second sliders 514 is threadedly connected to a corresponding set of second lead screws 513 and is connected to a corresponding set of clamping plates 504.

[0046] During the assembly of the sealing gasket for the fire hose connector, the industrial robotic arm 4 moves the clamping block 502 to the corresponding position. Then, by controlling the rotation of two sets of second lead screws 513, and through the threaded connection between the two sets of second lead screws 513 and two sets of second sliders 514, the two sets of second sliders 514 drive the two sets of clamping plates 504 to clamp the fire hose connector. Several sets of limiting rollers 505 then abut against the outer wall of the connector. The connector is then transferred, and the electric turntable 501 rotates the connector, while the drive wheel 508 abuts against... The contact point on the outer wall of the connector drives the connector to rotate, connecting the two sets of connectors. Then, the swing rod 509 drives the sealing airbag 511 to rotate into the connector, and gas is delivered through the jet nozzle 510. Part of the gas is delivered into the sealing airbag 511, causing it to expand and seal the two sets of connectors. Then, by monitoring whether there is air leakage at the connection, the assembly effect of the sealing gasket is judged. This realizes the integrated drive effect of loading, unloading and sorting of fire hose connectors, optimizes the assembly process, and improves the assembly effect of the assembly equipment while improving the sealing detection efficiency of fire hose connectors.

[0047] By controlling the industrial robotic arm 4 to move the clamping block 502 to the corresponding position, and then controlling the two sets of clamping plates 504 to clamp the fire hose connector, several sets of limiting rollers 505 abut against the outer wall of the connector. After flipping the connector, the drive wheel 508 is controlled to abut against the outer wall of the connector to drive the connector to rotate, which can connect the two sets of connectors. Then, the jet nozzle 510 is controlled to enter the corresponding connector to deliver gas. Then, by monitoring whether there is air leakage at the connection, the assembly effect of the sealing gasket is judged. The integrated drive effect of loading, unloading and sorting of fire hose connectors is realized, the assembly process is optimized, and the assembly effect of the assembly equipment is improved while the sealing detection efficiency of the fire hose connector is improved.

[0048] By controlling the annular sealing gasket on the sealing gasket assembly box 204 to be pressed into the sealing ring seat of the connector interface, then controlling the lifting plate 203 to rise, and then controlling several sets of electric folding rods 208 at the bottom of the rotating ring 206 to move the detector 209 to the assembled sealing gasket, so that several sets of telescopic probes 211 abut against the top of the sealing gasket. Then, controlling the rotating ring 206 to drive several sets of detectors 209 to rotate continuously, by monitoring and recording the feedback pressure of the telescopic probes, it is confirmed whether the sealing gasket is flat. When the sealing gasket is not flat, controlling the pressure ring 210 on the detector 209 to abut against the top of the sealing gasket, the telescopic probes 211 are pressed into the detector 209. Then, controlling several sets of pressure rings 210 to rotate one revolution to flatten the sealing gasket, thereby improving the assembly quality of the connector sealing gasket of the assembly equipment.

[0049] The fire hose connector assembled by the loading and unloading mechanism 5 is unloaded and flipped. Then, the loading and unloading mechanism 5 connects the flipped connector to the next set of connectors to maintain communication. Gas is then introduced into the connector. Since the bottom of the lower connector can be sealed, several sets of first air pressure sensors 3072 and second air pressure sensors 3075 set on the inner walls of the guide plate 3071 and the two sets of extension plates 3074 can detect air leakage at the connection between the two sets of connectors. The two sets of extension plates 3074 can be controlled by the guide gear 3077 to retract into the telescopic cavity 3073. Without affecting the loading and unloading of the fire hose connector, the quality of the assembly equipment's detection of the airtightness of the assembled fire hose connector is improved.

[0050] By controlling the loading and unloading mechanism 5, the fire hose connectors are sequentially transferred to several sets of assembly slots 303 on the circulating transfer mechanism 3. The interface of the connector is locked onto the support plate 304. A corresponding lifting baffle can be set below the support plate 304 to support the bottom of the connector. Then, two sets of limit stops are controlled to limit and fix the connector to prevent displacement during assembly. When the fire hose connector completes the sealing gasket assembly on the rotating plate 302 and moves back to the loading and unloading robot, the loading and unloading mechanism 5 unloads the assembled fire hose connector and inserts a new fire hose connector. This ensures the continuity of the sealing gasket assembly work of the fire hose connector and improves the working efficiency of the assembly equipment.
